Sometimes, you want to initialize a variable to some value only if that variable is equal to nil. If you like to write your methods as short, clean and readable as possible, you can do that task in a single line instead of taking the traditionnal 3 lines approach. You have two options :

\n\n

1) You can use the if modifier 1. x = get_some_object if x.nil?Very easy to read. This is my favorite.

\n\n

2) Or you can use the ||= operator 1. x ||= get_some_object This one is even shorter. The ||= operator is a little bit less verbose and might confuse a ruby newcomer… but I’m not saying that it should be a reason for not using it. This is more a matter of personal taste than anything else.Both of these methods are better than this :

\n\n
    \n

  1. #eeww… we don’t like this one.

    2. \n

  2. if(x.nil?)

    3. \n
  3. x = get_some_object   4.  end\n

\n但是值得说的是，libmmseg本来是被作者用来实现Sphinx全文检索软件的中文分词功能，因此作者给Sphinx提供了一个补丁文件，可以让Sphinx集成libmmseg，从而支持对于中文文章的全文检索功能，关于这一点可以看《Rails程序员Sphinx中文全文检索安装指南》的介绍。
\n所以，如果你要在Rails中做全文检索的话，我推荐您使用的是Sphinx + libmmseg + Ultrasphinx来实现，其简单高效，且支持并发，再仔细说一下：
\n1、Sphinx，是俄罗斯的Andrew Aksyonoff 开发的，被人叫做“狮身人面”，关于其高效的介绍，你可以参考《JavaEye3.0开发手记之三 － 狮身人面》，其性能出色，和架构清晰，学习成本很低，且其和数据库结合的很棒。其他相关介绍可以参考“coreseek对Sphinx的就介绍”，也可以参考其发布的《Coreseek 全文检索服务器 2.0 (Sphinx 0.9.8)参考手册》，其Coreseek就是基于Sphinx的一个全文搜索服务器。
\n2、libmmseg，就是前面说的中文分词程序，当前最新版本是0.73，采用C++开发，同时支持Linux平台和Windows平 台，切分速度大约在300K/s（PM-1.2G），libmmseg从0.7.2版本开始，作者提供了ruby调用的接口，所以我们可以直接在ruby 程序里面调用libmmseg进行分词，相当方便。
\n3、Ultrasphinx，是一个Rails插件，Rails开发人员可以使用它来很方便地调用Sphinx的功能。其他类似的插件有acts_as_sphinx，使用其可以很方便的在Rails中整合Sphinx。

\n\n

以上三个的安全不是很复杂，推荐是在Unix上，请参考《Rails程序员Sphinx中文全文检索安装指南》，这个文章就是基于以上三个组件的安装和使用说明。我会在近期发布出一些笔记和文档，以帮助需要的朋友更好的实现自己的全文检索。

Rails在WEB开发中独树一帜，取得相当大的成功，但是其内核中尚未支持WML，于是查找了一些资料，如果你使用Rails开发的系统向添加WAP支持，这或许对你有用。
\n\n
总的来看，有两个方式来实现对WML的支持，单独支持和整合支持，下面详细的说。
\n\n
一、按照一般方式支持
\n\n
这个方式和做PC WEB方式是一样的，有个单独的controller或者action，指定特有的layout和页面模板，而这些模板中采用WML语言编写，在请求到来的时候，按照URL中特有的特征字符（比如二级域名）或者Http Head中的标识转向Wap的action，进而显示。详细的步骤基本上是这样的：
\n\n
1、在app/controllers/application.rb中增加对WAP格式输出的支持
\n
\nRuby代码
\n
\n    before_filter :set_wap_content_type, :only => :wap  
\n      
\n    def set_wap_content_type  
\n      @headers["Content-Type"] = “text/vnd.wap.wml; charset=iso-8859-1″  
\n    end  
\n
\n
\n2、添加一个WAP的全局布局模板app/views/layouts/wap.rhtm
\n
\nXML/HTML代码
\n
\n    <?xml version=”1.0″?>  
\n    <!DOCTYPE wml PUBLIC “-//WAPFORUM//DTD WML 1.1//EN” “http://www.wapforum.org/DTD/wml_1.1.xml”>  
\n    <wml>  
\n    <card title=”<%= @title %>”>  
\n    <p align=”center”>  
\n    <%= @content_for_layout %>  
\n    </p>  
\n    </card>  
\n    </wml>  
\n
\n
\n3、在我的controller中（index）中增加一个action用来响应WAP请求。
\n
\nRuby代码
\n
\n    def wap  
\n      @title = "San Francisco Sailing Weather"  
\n      render(:layout => "wml")  
\n    end  
\n
\n
\n4、添加相应的view模板app/views/index/wap.rhtml
\n
\nXML/HTML代码
\n
\n    <%= link_to 'NOAA Marine Forecast', { :controller => '/marine/forecast', :action => 'wap' } %><br/>  
\n    <%= link_to 'Wind Readings', { :controller => '/marine/wind', :action => 'wap' } %><br/>  
\n    <%= link_to 'Current Predictions', { :controller => '/marine/tide', :action => 'wap' } %>  
\n
\n
\n 
\n\n
二、使用Rails2支持的多模板类型支持
\n\n
在Rails2以后，Rails支持多种格式的输出，比如Html，RSS，JS等，当然你还可以定制自己的格式，比如我们这里说的WML，Iphone等，使用起来更简单、自然。
\n\n
1、添加MIME格式支持
\n\n
在config/environment.rb中增加MIME的格式支持，方式如下：
\n
\nRuby代码
\n
\n    Mime::Type.register "text/vnd.wap.wml", :wml  
\n
\n
\n
\n2、判断请求类型
\n<div class="codeText">
\n<div class="codeHead">Ruby代码</div>
\n<ol class="dp-rb" start="1">
\n    <li class="alt"><span><span class="comment"># application.rb</span><span>  </span></span></li>
\n    <li><span>before_filter <span class="symbol">:adjust_format_for_beta</span><span>  </span></span></li>
\n    <li class="alt"><span>  </span></li>
\n    <li><span>...  </span></li>
\n    <li class="alt"><span>  </span></li>
\n    <li><span><span class="keyword">def</span><span> adjust_format_for_beta  </span></span></li>
\n    <li class="alt"><span>  request.format = <span class="symbol">:beta</span><span> </span><span class="keyword">if</span><span> beta_request?   </span></span></li>
\n    <li><span><span class="keyword">end</span><span>  </span></span></li>
\n    <li class="alt"><span>  </span></li>
\n    <li><span><span class="keyword">def</span><span> beta_request?  </span></span></li>
\n    <li class="alt"><span>  <span class="keyword">return</span><span> (request.subdomains.first == </span><span class="string">"beta"</span><span> || params[</span><span class="symbol">:format</span><span>] == </span><span class="string">"beta"</span><span>)  </span></span></li>
\n    <li><span><span class="keyword">end</span><span>  </span></span></li>
\n</ol>
\n</div>
\n<pre style="font-size: 90%;">
\n<strong>3、添加相应的view代码</strong>比较简单，就是写XML或者WML模板<strong>show.wml.erb</strong>
\n
\nXML/HTML代码
\n
\n    xml.instruct! :xml, :version => "1.0"  
\n    xml.wml "xml:lang" => "en-gb" do  
\n      xml.card :title => "My title here" do  
\n        xml.p "Something interesting here"  
\n        xml.p "Something else interesting here."  
\n      end  
\n    end  
\n
\n
\n
\n4、添加输出类型支持
\n<div class="codeText">
\n<div class="codeHead">Ruby代码</div>
\n<ol class="dp-rb" start="1">
\n    <li class="alt"><span><span class="keyword">def</span><span> index  </span></span></li>
\n    <li><span>  respond_to <span class="keyword">do</span><span> |format|  </span></span></li>
\n    <li class="alt"><span>    format.html  </span></li>
\n    <li><span>    format.wml  </span></li>
\n    <li class="alt"><span>  <span class="keyword">end</span><span>  </span></span></li>
\n    <li><span><span class="keyword">end</span><span>  </span></span></li>
\n</ol>
\n</div>
\n<pre style="font-size: 90%;">

\r\n
Java代码
\r\n
    \r\n\t
  1. public String getIpAddr(HttpServletRequest request) { 
    2. \r\n\t
  2.  String ip = request.getHeader(\"x-forwarded-for\"); 
    3. \r\n\t
  3.  if(ip == null || ip.length() == 0 || \"unknown\".equalsIgnoreCase(ip)) { 
    4. \r\n\t
  4.  ip = request.getHeader(\"Proxy-Client-IP\"); 
    5. \r\n\t
  5.  } 
    6. \r\n\t
  6.  if(ip == null || ip.length() == 0 || \"unknown\".equalsIgnoreCase(ip)) { 
    7. \r\n\t
  7.  ip = request.getHeader(\"WL-Proxy-Client-IP\");

    14. \r\n
\r\n

\n\n
我找到那块的代码，跟了一遍流程发现逻辑没有啥问题，但是最终的结果却还是鉴权不通过，实在有些诡异。其基本逻辑为先取得配置的IP列表，然后通过request.getRemoteAddr()取得客户端的IP地址，做鉴权和校验，逻辑没问题，那么肯定是request.getRemoteAddr()出了问题，google下，发现有人遇到类似的问题。
\n\n
最终定位为request.getRemoteAddr()这种方法在大部分情况下都是有效的。但是在通过了Apache,Squid等反向代理软件就不能获取到客户端的真实IP地址了。
\n\n
如果使用了反向代理软件，将http://192.168.1.110:2046/ 的URL反向代理为http://www.xxx.com/ 的URL时，用request.getRemoteAddr()方法获取的IP地址是：127.0.0.1　或　192.168.1.110，而并不是客户端的真实ＩＰ。
\n\n
经过代理以后，由于在客户端和服务之间增加了中间层，因此服务器无法直接拿到客户端的IP，服务器端应用也无法直接通过转发请求的地址返回给客户端。但是在转发请求的HTTP头信息中，增加了X－FORWARDED－FOR信息用以跟踪原有的客户端IP地址和原来客户端请求的服务器地址。
\n原来如此，我们的项目中正好是有前置apache，将一些请求转发给后端的weblogic，看来就是这样导致的咯。
\n\n
给出一份还算靠谱的代码，如下：
\n
\nJava代码
\n
\n    public String getIpAddr(HttpServletRequest request) { 
\n     String ip = request.getHeader("x-forwarded-for"); 
\n     if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { 
\n     ip = request.getHeader("Proxy-Client-IP"); 
\n     } 
\n     if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { 
\n     ip = request.getHeader("WL-Proxy-Client-IP"); 
\n     } 
\n     if(ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) { 
\n     ip = request.getRemoteAddr(); 
\n     } 
\n     return ip; 
\n    } 
\n
\n
\n如果有人遇到类似问题，请多加留意，呵呵。
\n\n
PS：可是，如果通过了多级反向代理的话，X-Forwarded-For的值并不止一个，而是一串Ｉｐ值，究竟哪个才是真正的用户端的真实IP呢？
\n答案是取X-Forwarded-For中第一个非unknown的有效IP字符串。如：X-Forwarded-For：192.168.1.110, 192.168.1.120, 192.168.1.130, 192.168.1.100,用户真实IP为： 192.168.1.110

\n-----------------使用---------------
\n好,下面来个简单教程.标准的 git 教程是行不通的(要加些东西),因为这是windows.主要是没有用户信息.好我的git安装在 c:\\git 以下为命令行.
\n
\n1.创建git的数据库
\nC:\\Git\\bin>git init-db
\n\n
2.生成一个文件xxx并加入到git中
\nC:\\Git\\bin>echo hello > xxx
\nC:\\Git\\bin>git add xxx
\n\n
3.提交[以上两步与标准教程还是一样的,关键是这一步]
\nC:\\Git\\bin>set home=c:\\
\nC:\\Git\\bin>git config --global user.name "clq"
\nC:\\Git\\bin>git commit -m "test"
\n\n
一共三个命令,其中第1个是设置用户路径,第2个是设置用户名.而且是每次打开dos命令行后都要有这两个命令,当然你可以写成 bat 文件.第3个才是提交,不能直接写 git commit 因为这个版本好象一定要有注释,那个 "test" 就是我加的注释了.
\n\n
4.改一下xxx文件
\necho world >> xxx
\n\n
5.查看一下它和我们原来对比的有什么不同
\nC:\\Git\\bin>git diff
\n\n
结果如下
\ndiff --git a/xxx b/xxx
\nindex 907cd4b..360c7f4 100644
\n--- a/xxx
\n+++ b/xxx
\n@@ -1 +1,2 @@
\nhello
\n+world
\n(END)
\n\n
用过cvs的都明白了吧.另外这个显示的还得退出,退出命令和vi一样
\n提交可以用一个命令来完成
\ngit commit -m "" -a xxx
\n\n
省去git add
\n\n
C:\\Git\\bin>git show xxx
\n查看最近一次提交的信息.
\n\n
C:\\Git\\bin>git commit -a -m"aa"
\n\n
提交全部更改过的文件.

    12. \r\n\t
  12.     shows output from conversion tool.  
    13. \r\n\t
  13. -p or --pretend  
    14. \r\n\t
  14.     don't convert anything. sneetchalizer will go through the motions and print out the commands it would run. Useful for preview- ing a complex command line to ensure it does what you intend. You should interpret this option's output with a grain of salt. For example, if you include the '--sanitize' option, the files will not really be renamed when using --pretend, and as such the command's output will not reflect that the filenames would be changed during an actual run.  
    15. \r\n\t
  15. -t or --terminate  
    16. \r\n\t
  16.     terminate sneetchalizer options. This is useful if you have to convert '--coolDir' or '-groovySong.mp3'. This is the only option whose order on the command line is significant.  
    17. \r\n\t
  17. -D ARG or --out-directory=ARG  
    18. \r\n\t
  18.     write all outfiles to a directory argument. This is useful if you want to (re)encode files directly to a mounted portable device.  
    19. \r\n\t
  19. --strict and --pedantic  
    20. \r\n\t
  20.     many errors that sneetchalizer may encounter are recoverable, such as specifying a directory as argument that contains no files to convert, or conversion failures in general. By default the script will print an error message and move on to the next file. If you use '--strict' then sneetchalizer will bail out at the first sign of trouble except for tag errors. With '--pedantic' the script will stop even on tag errors.   
    21. \r\n\t
  21. --stasis  
    22. \r\n\t
  22.     Preserve timestamp (mtime) of original file.  
    23. \r\n\t
  23. --threads [N]  
    24. \r\n\t
  24.     Experimental. Use threads to create concurrent jobs. This option takes an optional integer argument which represents the number of threads to launch. The default is two. Preliminary tests suggest there is little advantage (and even diminishing returns) when setting this number greater than the number of cores/CPUs you have. Due to the asychronous nature of threads the --verbose and --show-output flags will be silently disabled and most screen output is supressed.   
    25. \r\n\t
  25. --sanitize  
    26. \r\n\t
  26.     Removes ,, ;, :, ', \", %, @, #, and ` from filenames and tags.  
    27. \r\n\t
  27. -n [FORMAT] or --rename[=FORMAT]  
    28. \r\n\t
  28.     rename all outfiles (and temporary wavs) according to FORMAT. FORMAT is a string with special designators to be pulled from the file tags. The following options are available:  
    29. \r\n\t
  29.   
    30. \r\n\t
  30.         * %t Song title

  45.     mp3/ogg quality.  
    46. \r\n\t
  46.   
    47. \r\n\t
  47. quality and bitrate are passed directly to lame or oggenc depending on mp3 or ogg output format respectively. Both tools can handle either a bitrate or quality argument, so it is important to understand what values are valid for the underlying tool in your specific use case. faac will accept a bitrate argument, but not a quality argument. These options will be silently ignored for any output formats other than mp3, ogg or m4a. Make sure you know what you are doing if you decide to use both in one run, and read each tools manpage for valid values. If these options are omitted the tools builtin defaults are used (-q3 for oggenc and -q5 for lame).

    51. \r\n\t
  51.   
    52. \r\n\t
  52. this option allows you to pass a compression argument to flac and mac. See 'flac --help' and/or 'mac --help' if you don't know what this means.

    60. \r\n\t
  60.   
    61. \r\n\t
  61. Valid output formats are: \"aac\", \"aif\", \"aifc\", \"aiff\", \"aiffc\", \"ape\", \"au\", \"cdr\", \"cdda\", \"copy\", \"flac\", \"m4a\", \"m4b\", \"mpc\", \"mp4\", \"mpp\", \"mp3\", \"mp2\", \"ofr\", \"ofs\", \"ogg\", \"snd\", \"spx\", \"tta\", \"wav\", \"wv\". Valid input formats are all of the above plus \"wma\". You can specify multiple input formats using a comma: 'mp3,m4a,wma'. Input format is only neccesary when passing directory arguments, as file arguments are handled by context (read: file extension). The \"copy\" output option copies files directly, bypassing decoding/encoding steps (useful in conjunction with --rename).  
    62. \r\n\t
  62.   
    63. \r\n\t
  63. Tagging Options:

    88. \r\n\t
  88.   
    89. \r\n\t
  89. The default is still 'lame'. If 'lame' is not found, the script will search for one of these two encoders regardless if these options are passed or not.  
    90. \r\n\t

\r\n另外，你可以运行sneetchalizer -h看到简要的使用说明，也可以使用sneetchalizer --help看到详细的使用信息。\r\n\r\n3、使用示例\r\n\r\n如下简要的写几个使用的示例：\r\n
\r\n
使用示例：
\r\n
    \r\n\t
  1. $ sneetchalizer song.mp3  
    2. \r\n\t
  2.   
    3. \r\n\t
  3. The most simple possible example, creates 'song.wav'.  
    4. \r\n\t
  4.   
    5. \r\n\t
  5. $ sneetchalizer --out=ogg --in=flac -q5 /some/music/dir  
    6. \r\n\t
  6.   
    7. \r\n\t
  7. This example converts every flac file in '/some/music/dir' to ogg format at quality 5.  
    8. \r\n\t
  8.   
    9. \r\n\t
  9. $ sneetchalizer -d --out=mp3 --in=ogg,m4a,wma -b 160 .  
    10. \r\n\t
  10.   
    11. \r\n\t
  11. Converts every ogg, m4a, and wma file in the current directory to a 160 kbps constant bitrate mp3 file. The original files are deleted.  
    12. \r\n\t
  12.   
    13. \r\n\t
  13. $ sneetchalizer --out=mp3 --out-optionhook=\"--preset extreme\" /some/wavs  
    14. \r\n\t
  14.   
    15. \r\n\t
  15. Here we encode every wav in '/some/wavs' to mp3 format passing '--preset extreme' directly to lame.  
    16. \r\n\t
  16.   
    17. \r\n\t
  17. $ sneetchalizer --in=ogg --out=ogg --quality=1 norvegianWood.ogg /some/more/oggs  
    18. \r\n\t
  18.   
    19. \r\n\t
  19. Using the same --in and --out format allows us to resample/encode the file at a different bitrate or quality. Note that this will overwrite the original file so only do this on a copy, or use '-D' to write files to another directory.  
    20. \r\n\t
  20.   
    21. \r\n\t
  21. $ sneetchalizer --in=ogg --out=m4a -D /mnt/ipod/ /some/oggs  
    22. \r\n\t
  22.   
    23. \r\n\t
  23. Here we re-encode some ogg files to m4a format and write them to our mounted iPod.   
    24. \r\n

\r\n4、注意事项\r\n\r\n本脚本只是粘合剂，其他的tool还是需要另外安装的。\r\n\r\n其他信息请参考其主页说明,如果您有这个方面的问题或经验，欢迎和我讨论。\r\n\r\n\r\n\r\n\r\n ", "created_at"=>2008-10-09 02:49:27 UTC, "updated_at"=>2012-06-24 15:35:09 UTC, "body_html"=>"
前几天写了“采用Ruby提取MP3的metadata信息”后，就在寻找成熟的Ruby代码做差不多的事情，今天找到一个sneetchalizer，仔细的看了下，非常强大。
\n\n\n
sneetchalizer其实只是个粘合剂，因为在*unix下，audio格式转换的lib已经非常丰富和成熟，例如lame,gogo,bladeenc,mplayer等等就非常好用；另外，关于audio的tag信息和metadata信息的提取也有比较成熟的lib了，类似id3lib-ruby library,wmainfo-rb library,ruby-ogginfo library等等。而sneetchalizer只是把这些tools粘合起来。
\n\n
其支持的格式有:'aac' 'aif' 'aifc' 'aiff' 'aiffc' 'ape' 'au' 'caf' 'cdda' 'cdr' 'copy' 'fap' 'flac' 'gsm''ircam' 'm4a' 'm4b' 'mat' 'mat4' 'mat5' 'mp2' 'mp3' 'mp4' 'mpc' 'mpp' 'nist' 'ofr''ofs' 'ogg' 'paf' 'pvf' 'raw' 'sd2' 'sds' 'sf' 'snd' 'spx' 'svx' 'tta' 'voc''vox' 'w64' 'wav' 'wma' 'wv' 'xi'
\n\n
使用sneetchalizer可以实现audio文件的格式转换和tag信息提取和写入，详细使用方法参考其主页上说明，下面简要的说说起安装方法和使用参数：
\n\n
1、安装方法

\n\n
2、参数解释
\n\n
不翻译了，都挺简单明了的，如下：
\n
\nXML/HTML代码
\n
\n    General options:

\n        shows output from conversion tool.  
\n    -p or --pretend  
\n        don't convert anything. sneetchalizer will go through the motions and print out the commands it would run. Useful for preview- ing a complex command line to ensure it does what you intend. You should interpret this option's output with a grain of salt. For example, if you include the '--sanitize' option, the files will not really be renamed when using --pretend, and as such the command's output will not reflect that the filenames would be changed during an actual run.  
\n    -t or --terminate  
\n        terminate sneetchalizer options. This is useful if you have to convert '--coolDir' or '-groovySong.mp3'. This is the only option whose order on the command line is significant.  
\n    -D ARG or --out-directory=ARG  
\n        write all outfiles to a directory argument. This is useful if you want to (re)encode files directly to a mounted portable device.  
\n    --strict and --pedantic  
\n        many errors that sneetchalizer may encounter are recoverable, such as specifying a directory as argument that contains no files to convert, or conversion failures in general. By default the script will print an error message and move on to the next file. If you use '--strict' then sneetchalizer will bail out at the first sign of trouble except for tag errors. With '--pedantic' the script will stop even on tag errors.   
\n    --stasis  
\n        Preserve timestamp (mtime) of original file.  
\n    --threads [N]  
\n        Experimental. Use threads to create concurrent jobs. This option takes an optional integer argument which represents the number of threads to launch. The default is two. Preliminary tests suggest there is little advantage (and even diminishing returns) when setting this number greater than the number of cores/CPUs you have. Due to the asychronous nature of threads the --verbose and --show-output flags will be silently disabled and most screen output is supressed.   
\n    --sanitize  
\n        Removes ,, ;, :, ', ", %, @, #, and ` from filenames and tags.  
\n    -n [FORMAT] or --rename[=FORMAT]  
\n        rename all outfiles (and temporary wavs) according to FORMAT. FORMAT is a string with special designators to be pulled from the file tags. The following options are available:  
\n      
\n            * %t Song title  
\n            * %b Album title  
\n            * %n Track number  
\n            * %a Artist name  
\n            * %y Year  
\n            * %g Genre  
\n            * %c Comment field  
\n      
\n        Directories may be created with this command, as in "%b/%n - %t". The default value of FORMAT is "%n %t".   
\n      
\n    Bitrate/Quality/Compression options:  
\n      
\n    -b or --bitrate  
\n        mp3/ogg/m4a bitrate.  
\n    -q or --quality  
\n        mp3/ogg quality.  
\n      
\n    quality and bitrate are passed directly to lame or oggenc depending on mp3 or ogg output format respectively. Both tools can handle either a bitrate or quality argument, so it is important to understand what values are valid for the underlying tool in your specific use case. faac will accept a bitrate argument, but not a quality argument. These options will be silently ignored for any output formats other than mp3, ogg or m4a. Make sure you know what you are doing if you decide to use both in one run, and read each tools manpage for valid values. If these options are omitted the tools builtin defaults are used (-q3 for oggenc and -q5 for lame).  
\n      
\n    -c or --compression  
\n        flac/mac compression level.  
\n      
\n    this option allows you to pass a compression argument to flac and mac. See 'flac --help' and/or 'mac --help' if you don't know what this means.  
\n      
\n    Format Options:  
\n      
\n    --out=format  
\n        output format. Default is wav.  
\n    --in=format[,format..]  
\n        input format(s). Default is wav.  
\n      
\n    Valid output formats are: "aac", "aif", "aifc", "aiff", "aiffc", "ape", "au", "cdr", "cdda", "copy", "flac", "m4a", "m4b", "mpc", "mp4", "mpp", "mp3", "mp2", "ofr", "ofs", "ogg", "snd", "spx", "tta", "wav", "wv". Valid input formats are all of the above plus "wma". You can specify multiple input formats using a comma: 'mp3,m4a,wma'. Input format is only neccesary when passing directory arguments, as file arguments are handled by context (read: file extension). The "copy" output option copies files directly, bypassing decoding/encoding steps (useful in conjunction with --rename).  
\n      
\n    Tagging Options:  
\n      
\n    --tt or --title  
\n        Set 'title' tag.  
\n    --ta or --artist  
\n        Set 'artist' tag.  
\n    --tl or --album  
\n        Set 'album' tag.  
\n    --ty or --year  
\n        Set 'year' tag.  
\n    --tc or --comment  
\n        Set 'comment' tag.  
\n    --tg or --genre  
\n        Set 'genre' tag.  
\n    --tn or --trackn  
\n        Set 'track number' tag.  
\n      
\n    The short and long versions are different in an important way: Using the long version will clobber any existing tags. The short version will only set the tag if the existing tag has no value. Note that these tags will be placed in _every_ outfile during the run.  
\n      
\n    Alternative Encoder/Decoder Options:  
\n      
\n    --gogo  
\n        use gogo to encode mp3 files.  
\n    --bladeenc  
\n        use bladeenc to encode mp3 files.  
\n      
\n    The default is still 'lame'. If 'lame' is not found, the script will search for one of these two encoders regardless if these options are passed or not.  
\n      
\n    Special Options:  
\n      
\n    --in-optionhook=ARG  
\n        add ARG to infile conversion command. Possibly dangerous!  
\n    --out-optionhook=ARG  
\n        add ARG to outfile conversion command. Possibly dangerous!   
\n

\n另外，你可以运行sneetchalizer -h看到简要的使用说明，也可以使用sneetchalizer --help看到详细的使用信息。
\n\n
3、使用示例
\n\n
如下简要的写几个使用的示例：
\n
\n使用示例：
\n
\n    $ sneetchalizer song.mp3  
\n      
\n    The most simple possible example, creates 'song.wav'.  
\n      
\n    $ sneetchalizer --out=ogg --in=flac -q5 /some/music/dir  
\n      
\n    This example converts every flac file in '/some/music/dir' to ogg format at quality 5.  
\n      
\n    $ sneetchalizer -d --out=mp3 --in=ogg,m4a,wma -b 160 .  
\n      
\n    Converts every ogg, m4a, and wma file in the current directory to a 160 kbps constant bitrate mp3 file. The original files are deleted.  
\n      
\n    $ sneetchalizer --out=mp3 --out-optionhook="--preset extreme" /some/wavs  
\n      
\n    Here we encode every wav in '/some/wavs' to mp3 format passing '--preset extreme' directly to lame.  
\n      
\n    $ sneetchalizer --in=ogg --out=ogg --quality=1 norvegianWood.ogg /some/more/oggs  
\n      
\n    Using the same --in and --out format allows us to resample/encode the file at a different bitrate or quality. Note that this will overwrite the original file so only do this on a copy, or use '-D' to write files to another directory.  
\n      
\n    $ sneetchalizer --in=ogg --out=m4a -D /mnt/ipod/ /some/oggs  
\n      
\n    Here we re-encode some ogg files to m4a format and write them to our mounted iPod.

当网站访问量大到一定程度后，其web server会有大量的访问和错误日志，比如apache，nginx等就常常很容易的达到几个G的日志文件，这个时候就会导致诸如磁盘空间紧张，系统反应迟钝等等系列的问题，需要手工清理日志。
\n\n
其实我们可以采取一些方法使得其日志自动回滚和删除，这里大概说说，后续再补充。
\n\n
1、Nginx Log Rotation
\n\n
Nginx有个Log Rotation模块，nginx will re-open it's logs in response to the USR1 signal.参考如下脚本：
\n`$ mv access.log access.log.0$ kill -USR1cat master.nginx.pid`$ sleep 1$ gzip access.log.0    # do something with access.log.0
\n\n
2、自己写脚本#!/bin/shlog_dir="/var/log/httpd"yesterday=date +%Y%m%d -d '-1 day'lastday =date +%Y%m%d -d '-1 month'/bin/rm ${log_dir}/access.${lastday}.log/bin/rm ${log_dir}/error.${lastday}.log/bin/mv ${log_dir}/access.log ${log_dir}/access.${yesterday}.log/bin/mv ${log_dir}/error.log ${log_dir}/error.${yesterday}.logkill -USR1 cat /var/run/nginx.pid/bin/gzip ${log_dir}/access.${yesterday}.log &/bin/gzip ${log_dir}/error.${yesterday}.log &本脚本来自“Nginx的日志回滚”然后将该脚本保存在/etc/cron.daily目录里，或者在crontab里每日0点时运行。另外，还可以结合awstats进行日志分析，这里就不详细说了，可以参考车东的相关文章。```

在Android中使用GoogleMap非常方便，但是有些小技巧或者注意事项你必须牢记，否则调试半天你也不会找到啥线索，浪费时间不说，更让你狂抓，以下技巧都是我在实际项目中遇到的，不断更新和维护，如果你有类似技巧，欢迎分享：
\n
（以下技巧是基于SDK 1.0的）
\n
一、申请Apikey，并放在正确的位置
\n
这个应该都知道，但是是申请得到的key放哪里很多人不知道，可以放在
\n
1、XML布局文件中
\n
<view android:id="@+id/mv"
\n   class="com.google.android.maps.MapView"
\n   android:layout_width="fill_parent"
\n   android:layout_height="fill_parent"
\n   android:layout_weight="1" 
\n   android:apiKey="01Yu9W3X3vbpYT3x33chPXXX7U1Z6jy8WYZXNFA" 
\n   />
\n
2、java中
\n
        mMapView = new MapView(this, "01Yu9W3X3vbpYT3x33chPxxx7U1Z6jy8WYZXNFA");
\n
二、记得导入uses-library 
\n
 由于1.0版本的修改，使得map包不再是默认的了，使用的时候需要在manifest中的application节点下加入
\n
<uses-library android:name="com.google.android.maps" /> 
\n
\n
否则，你将遇到可恶的“java.lang.NoClassDefFoundError: ”，切记！
\n
三、需要给予一定的权限
\n
因为要使用GoogleMAP的service，所以需要
\n<uses-permission android:name="android.permission.INTERNET"></uses-permission>
\n
如果需要GPS等应用，还需要
\n
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
\n
四、Activity需要继承自MapActivity
\n
类似如下代码；
\n
package com.iceskysl.showmap;
\n
\nimport com.google.android.maps.MapActivity;
\n
\nimport android.os.Bundle;
\n
\npublic class ShowMap extends MapActivity {
\n    /** Called when the activity is first created. */
\n    @Override
\n    public void onCreate(Bundle savedInstanceState) {
\n        super.onCreate(savedInstanceState);
\n        setContentView(R.layout.main);
\n    }
\n
\n    @Override
\n    protected boolean isRouteDisplayed() {
\n        // TODO Auto-generated method stub
\n        return false;
\n    }
\n}
\n

早就见过Rails2中增加的Scope功能，但是一直没在意，今天遇到一个需求，想在@user.topics中按照条件返回指定的数量或者排序，发现按照以往的处理方法比较麻烦，也不够优雅，经一朋友指点，觉得Scope应该有戏，仔细看了下，果然适合我的这个场景，代码非常优雅，如下：
\n
    @albums =Album.scoped_by_singer_id(@artist.id).find(:all, :limit => 5)
\n不多说，应该都看得懂，如果你想了解更加详细的使用方法，你可以去下面的参考资料地址去看看，再举个例子：
\n
\n
Order.scoped_by_customer_id(12)
Order.scoped_by_customer_id(12).find(:all,
  :conditions => "status = 'open'")
Order.scoped_by_customer_id(12).scoped_by_status("open")```\n

早就见过Rails2中增加的Scope功能，但是一直没在意，今天遇到一个需求，想在@user.topics中按照条件返回指定的数量或者排序，发现按照以往的处理方法比较麻烦，也不够优雅，经一朋友指点，觉得Scope应该有戏，仔细看了下，果然适合我的这个场景，代码非常优雅，如下：
\n    @albums =Album.scoped_by_singer_id(@artist.id).find(:all, :limit => 5)
\n不多说，应该都看得懂，如果你想了解更加详细的使用方法，你可以去下面的参考资料地址去看看，再举个例子：
\n
\nOrder.scoped_by_customer_id(12)Order.scoped_by_customer_id(12).find(:all,  :conditions => "status = 'open'")Order.scoped_by_customer_id(12).scoped_by_status("open")```

Garry Tan, cofounder of Posterous, lists 12 lessons for scaling that apply to more than just Rails,and i mark some word below.
\n
\n
  • Use cloud storage for static files. --S3,I do not care it 's fine in china.
    • \n
  • Use HTTP Cache Control to tell the browser what it can cache.  --this is true,etag is great.
    • \n
  • Use Sphinx for text search.  --sometimes,you do have others chose.
    • \n
  • Use InnoDB for more crash resistant and faster writes.  --maybe it's right.
    • \n
  • Don't use textbook Rails ActiveRecord objects. Use New Relic to find exactly what is slow in your system. --yep
    • \n
  • Use memcache later so you find your database bottlenecks now. --this is very important.
    • \n
  • Use mongrel proctitle to find your slow queries. You are only as fast as your slowest queries. -maybe mongrel is not only chose,think about thin,ok?
    • \n
  • Use asynchronous job queuing to do work in parallel.  --yes,but sometimes crontab is enough.
    • \n
  • Use monitoring so you'll know when your site went down and why. --that's it,just do it.
    • \n
  • Learn by reading the source code, fixing problems, and submitting them back to the community.  --very userfull when you got some strange questions..
    • \n
  • Use new plugins. Old plugins can't be trusted. --and check chang histroy carefully.
    • \n
  • Use new information. Old information can't be trusted.  --and what's this?

    \n1.DYNAMICALLY LOADING CONFIG FILES INTO AN ALREADY RUNNING GOD
    \n
    \n
    God allows you to load or reload configurations into an already running instance. There are a few things to consider when doing this:
    \n
      \n    
    • Existng Watches with the same name``` as the incoming Watches will be overidden by the new config.
      • \n    
    • All paths must be either absolute or relative to the path from which god was started.
      • \n
    \n
    To load a config into a running god, issue the following command:
    \n
    $ sudo god load path/to/config.god
    # god load /data/www/api/config/config_thin_api.god```\n
    Config files that are loaded dynamically can contain anything that a normal config file contains, however, global options such as God.pid_file_directory``` blocks will be ignored (and produce a warning in the logs).

    出错了，这边表貌似被MERGE用了，查了一下，果然是被rails_logs这个表MERGE着用了，那我直接truncate这个rails_logs试试看。
    \n

    \n
    ERROR 1 (HY000): Can't create/write to file './iceskysl_beta_log/rails_logs.MRG' (Errcode: 17)
    \n
    \n
    呀，还是出错，文件不可写？Errcode: 17
    \n
    查下资料，原来：
    \n
    System error: 17 = File exists
    \n
    \n
    这咋回事，再查资料，原来.MRG是创建MERGE表的时候创建的，已经存在了。
    \n
    \n
    那就先把这个MERGE表干掉，再创建：
    \n
    先看下这个表是咋定义的：
    \n
    mysql>  show create table rails_logs;
    \n
    \n
    记录下SQL，接着drop掉。
    \n
    mysql> DROP  table rails_logs;
    \n
    Query OK, 0 rows affected (0.36 sec)
    \n
    \n
    再truncate我的目标表
    \n
    mysql> truncate table  rails_logs_081023;
    \n
    Query OK, 0 rows affected (4.22 sec)
    \n
    \n
    \n
    够快的，11042292条数据4S搞定，接着再创建下这个MERGE表，执行下上面记录的SQL就好了。
    \n
    \n
    最后确认下这表没啥问题：
    \n
    \n
    mysql> select count(id) from rails_logs;
    \n
    +-----------+
    \n
    | count(id) |

    \n
    +-----------+
    \n
    1 row in set (0.00 sec)

    OK，搞定，空间有了，天下太平了。

    \n
    \n
    问题：有一个拥有1亿条数据的表，只需要保留其中的5条，其他删除，如何做？
    \n
    这就需要用truncate table来搞定了，如下：
    \n
    select 5条数据 into #临时表 from 1亿条数据的牛X表
    \n
    truncate table 1亿条数据的牛X表
    \n
    --让它牛X，不到10毫秒干掉它。
    \n
    insert 1亿条数据的牛X表 select * from #临时表
    \n
    drop table #临时表

    \n   longest                                         #=> "sheep"
    \n\n
    # find the length of the longest word
    \n   longest = %w{ cat sheep bear }.inject(0) do |memo,word|
    \n      memo >= word.length ? memo : word.length
    \n   end
    \n   longest                                         #=> 5
    \n```
    \n\n
    然后根据我得需求，写出一个函数如下：
    \n`
    \n  # find the min abs size
    \n  def self.select_h(h)
    \n    if ALL_FORMATS.include?(h)
    \n      return h
    \n    else
    \n      ok_size = ALL_FORMATS.inject do |i,j|
    \n        (i-h).abs < (j-h).abs ? i : j
    \n      end
    \n      return ok_size
    \n    end
    \n  end
    \n
    \n首先看是否包含这个变量，如果又，直接返回，如果没有就inject来取一个最合适得。

At least I can still see what's happening. The main loop being in Ruby helps a lot too (especially if this were a much bigger program). How much of a difference does it make? time says: $ time ./cprimes.rb > /dev/null

    An order of magnitude improvement. Not too shabby.
    \nWhat's the lesson here? Optimize what you need to (and only what you need to), profile find out what that is (it may be slow, but profiling is your friend), and use the right tools (rewriting a bit of code with RubyInline is way better than rewriting the whole app in C).

    Example MySQL config file for large systems.
    \n\n
    This is for a large system with memory = 512M where the system runs mainly
    \n\n
    MySQL.
    \n\n
    You can copy this file to
    \n\n
    /etc/my.cnf to set global options,
    \n\n
    mysql-data-dir/my.cnf to set server-specific options (in this
    \n\n
    installation this directory is /var/lib/mysql) or
    \n\n
    ~/.my.cnf to set user-specific options.
    \n\n
    In this file, you can use all long options that a program supports.
    \n\n
    If you want to know which options a program supports, run the program
    \n\n
    with the "--help" option.
    \n\n
    The following options will be passed to all MySQL clients
    \n\n
    [client]

    配置
    \n\n
    那么应该怎样来配置成我喜欢的颜色呢？下面我们就来详细说一些这些配置。
    \n\n
    ~/.bash_profile是bash shell中当前登录用户的配置文件。bash是“终端”中默认的shell。
    \n\n
    alias ls=”ls -G”是给”ls -G”起了一个别名，当执行ls时，就相当于执行了ls -G。
    \n\n
    CLICOLOR是用来设置是否进行颜色的显示。CLI是Command Line Interface的缩写。
    \nLSCOLORS是用来设置当CLICOLOR被启用后，各种文件类型的颜色。LSCOLORS的值中每两个字母为一组，分别设置某个文件类型的文字颜色和背景颜色。LSCOLORS中一共11组颜色设置，按照先后顺序，分别对以下的文件类型进行设置：
    \n\n
    directory
    \nsymbolic link
    \nsocket
    \npipe
    \nexecutable
    \nblock special
    \ncharacter special
    \nexecutable with setuid bit set
    \nexecutable with setgid bit set
    \ndirectory writable to others, with sticky bit
    \ndirectory writable to others, without sticky bit
    \nLSCOLORS中，字母代表的颜色如下：
    \n\n
    a 黑色
    \nb 红色
    \nc 绿色
    \nd 棕色
    \ne 蓝色
    \nf 洋红色
    \ng 青色
    \nh 浅灰色
    \nA 黑色粗体
    \nB 红色粗体
    \nC 绿色粗体
    \nD 棕色粗体
    \nE 蓝色粗体
    \nF 洋红色粗体
    \nG 青色粗体
    \nH 浅灰色粗体
    \nx 系统默认颜色
    \n所以，如果我们想把目录显示成红色，就可以把LSCOLORS设置为bxfxaxdxcxegedabagacad就可以了

    \n我修改了send_file函数，并做了一个plugin 将起解压到vendor/plugins/就可以了
    \n（必要的地方我都写了注释，欢迎大家提出建议和意见）
    \n记录一下相关的code：
    \n 
    \nmodule ActionController
    \n  module Streaming
    \n    protected
    \n      def send_file(path, options = {})
    \n        raise MissingFile, "Cannot read file \#{path}" unless File.file?(path) and File.readable?(path)
    \n
        options[:length]   ||= File.size(path) # 文件长度\n    options[:filename] ||= File.basename(path) # 文件名称\n\n    options[:from] ||= 0 # 首偏移量（从哪里开始下载）\n    options[:to] ||= options[:length] # 结束位置\n\n    m_send_file_headers! options # 设置必要的 http 头\n\n    @performed_render = false\n\n    if options[:stream]\n      render :status => options[:status], :text => Proc.new { |response, output|\n        logger.info "Streaming file \#{path}" unless logger.nil?\n        len = options[:buffer_size] || 8192 # 原来的实现是4K， 不过APUE 上说，8K 要好一些，所有我调整了一下\n        File.open(path, 'rb') do |file|\n          file.seek(options[:from].to_i, IO::SEEK_SET) if options[:status] == 206 # 如果是多线程下载，则将流定位到首偏移量位置，从此处开始传输\n          while buf = file.read(len)\n            output.write(buf)\n          end\n        end\n      }\n    else\n      logger.info "Sending file \#{path}" unless logger.nil?\n      File.open(path, 'rb') { |file| render :status => options[:status], :text => file.read }\n    end\n  end\n\nprivate\n  def m_send_file_headers!(options)\n    options.update(DEFAULT_SEND_FILE_OPTIONS.merge(options))\n    [:length, :type, :disposition].each do |arg|\n      raise ArgumentError, ":\#{arg} option required" if options[arg].nil?\n    end\n\n    disposition = options[:disposition].dup || 'attachment'\n\n    disposition <<= %(; filename="\#{options[:filename]}") if options[:filename]\n\n# 先输出一些通用的HTTP头\n    headers.update(\n      'Content-Type'              => options[:type].strip,  # fixes a problem with extra '\\r' with some browsers\n      'Content-Disposition'       => disposition,\n      'Content-Transfer-Encoding' => 'binary'\n    )\n\n# 判断是否存在Range头，并使用正则表达式匹配 from 和 to\n# 如果匹配成功，则表示客户端使用多线程下载，同时一定要将http status 设置为 206\n    if request.env['HTTP_RANGE'] =~ /bytes=(\\d+)-(\\d*)/ then # 注意后一个\\d*，有一些多线程客户端并不完全符合http协议的要求（例如FlashGet）\n      options[:from] = $1\n      options[:to] = $2 unless $2.nil? # 如果客户端不标准，就将 to 设置为文件末尾\n\n  # 匹配成功，设置status 为 206\n      options[:status] = 206\n\n  # 一下3个http 头仅在多线程下载是有用\n      headers['Accept-Ranges'] = 'bytes'\n      headers['content-Range'] = "bytes \#{options[:from]}-\#{options[:to]}/\#{options[:length]}" # 格式为 bytes from-to/total\n      headers['Content-Length'] = options[:to].to_i - options[:from].to_i + 1 # 注意 在多线程下载下，Content-Length 为传输的实际字节数（从0开始算起，所有要+1）\n    else\n  # 非多现场下载\n      options[:status] = 200 # 请求正常标志\n      headers['Content-Length'] = options[:length] # 非多线程下载下，Content-Length为文件长度\n    end\n\n    headers['Cache-Control'] = 'private' if headers['Cache-Control'] == 'no-cache'\n  end\n
    \n
    \n\n
    end
    \nend
    \n```
    \n\n
    用法：
    \n 
    \nclass FileController 〈 ApplicationController
    \ndef download
    \n\n
    logger.debug request.env['Range'];
    \n\n
    request.env.each do |key, value|
    \n\n
    logger.debug key + '--------' + value
    \n\n
    end
    \n\n
    send_file 'public/jdk.tgz'
    \nend
    \nend

    现就相关事宜申明如下：
    \n一、我开发的所有程序都没有侵犯到用户的隐私。\n\n在这个应用中，申请的全部权限为：\n
    <uses-permission android:name=\"android.permission.INTERNET\" />
    \n
    <uses-permission android:name=\"android.permission.ACCESS_NETWORK_STATE\" />
    \n
    <uses-permission android:name=\"android.permission.WRITE_EXTERNAL_STORAGE\" />
    \n
    <uses-permission android:name=\"android.permission.SET_WALLPAPER\" />
    \n
    <uses-permission android:name=\"android.permission.READ_PHONE_STATE\" />
    \n
    <uses-permission android:name=\"android.permission.ACCESS_COARSE_LOCATION\" />
    \n懂点Android技术的都知道，这些权限都是为了让该软件的功能，能够正常工作所必须的权限（连接网络，获取网络状态，下载壁纸时读写SD卡，设置壁纸，读取手机状态）和Admob的广告精准推送所需要的权限（位置信息，读取手机状态）。\n至于获取用户浏览历史记录、短信、语音邮件密码的这些明显侵犯用户隐私的行为，完全是子虚乌有。一方面并没要申请相关的权限；另一方面我还真不知道怎样获取这些敏感信息。另外，admob的精准广告服务中可能是会针对用户的地理位置等信息推送更准确的广告服务。\n关于这款应用能获取的设备标识号是用来区分设备的唯一性，免去用户注册的麻烦，而能给用户提供收藏图片的功能；而诸如获取手机屏幕大小是为了能够智能适配合适的图片。在这些设备信息中，请问哪一条会侵犯到用户的隐私。\n另外说我可以获取浏览历史信息，这简直就是个天大的笑话。如果懂一点程序的就会知道，要获取浏览器信息必须在程序里申请com.android.browser.permission.READ_HISTORY_BOOKMARKS权限。我的程序完全没有获取到权限，怎么能够获取到历史信息，真是笑话！！！\n\n二、Android手机的权限管理，在任何没有刷过第三方rom的手机上是很严格的。\n Android手机的权限管理，在任何没有刷过第三方rom的手机上是很严格的，在没有相关权限的情况下，要获取那些信息，是完全不可能的。就算是被刷过Rom的手机，也只有具有该ROM制作人的加密签名的程序，才能完成一些不安全的操作。\n我所需要的权限在用户安装的时候会很明确的告诉用户，下面我就给大家展示一下我应用申请的权限和另外一个著名的壁纸的应用background和一款管理短信的应用申请的权限。\n\n我的软件需要的权限：\n\"\"\n\n看看background（另外一款壁纸的应用）申请的权限：\n\"\"\n\nHandcent SMS申请的权限：\n\n\"\"\n\n短信有短信的权限，联系人有联系人的权限，我都没要申请，请问我如何获取相关的信息。\n\n三、应用主要面向外国用户，但绝对没有获取那些高敏感度的隐私信息！\n\n该应用主要面向外国用户（国内由于网络原因无法正常使用），连接服务器端能够获取到精确适配终端的图片，这是一款非常有用，也深受用户喜爱的应用。它确实拥有数量众多（几百万）的用户，但绝对没有获取那些高敏感度的隐私信息！我每天都收到很多用户的反馈邮件告诉我这个软件多么棒，给他们带来多少乐趣！\n\n四、我本人始终与业界同仁一道，希望建立诚实守信、和谐共生的Android产业生态系统。\n\n随着Android开放性操作平台手机的广泛使用，其应用软件开发市场正呈现蓬勃发展景象。对于提醒用户警惕来自手机上的威胁，我本人向来都是强烈支持的！本人一直始终与业界同仁一道，一直为共建诚实守信、和谐共生的Android产业生态系统而努力，将力量专注于用户需求和技术创新，创造更被用户喜欢的软解，并致力于推动手机应用软件产业持续健康发展。\n\n在此，本人郑重申明，该应用没有获取任何诸如“浏览历史记录，短信，语音邮件密码等”这种高敏感度的信息，并和国外的原作者取得联系，让其修正自己的言论并发布公开道歉，同时对于这种不负责任的言论和评价观点，对我及与我相关的应用进行不负责任的报道造成的影响给予补偿，我将保留追究其法律责任的权利。\n\nps：\n\n如果您有其他的疑问或者问题，欢迎你在我sina微博客（http://t.sina.com.cn/iceskysl）或者sohu微博（http://t.sohu.com/iceskysl）给我沟通！\n
    update：
    \n写完申明后，去看消息出处看到其竟然做了修改，我早料到其会做相关的行为，所有早些时候截了屏幕如下：\n\n\"\"\n\n而现在的文章被修改为：\n\n\"\"\n\n看我用鼠标标识的地方，对关键信息进行了修改，感兴趣的人可以去 http://mobile.venturebeat.com/2010/07/28/android-wallpaper-app-that-steals-your-data-was-downloaded-by-millions/ 查看原文，对于这种标题党用子虚乌有的事情炒作，等消息传播后再修改自己的内容算什么行为！而对国内部分媒体在传播时不但不对真实性进行验证，还添油加醋，歪曲意思的报道，我非常无奈（看到有人还说可以获取信用卡信息，还加密传输，我实在无语）。\n\n按照我个人的感觉，他们应该紧接着要开始拿这个事件来炒作自己的产品了，我个人懒得去关注，如果有人发现有人借此炒作自己的产品，请帮忙分析分析，看看到底是什么人用这样手法。\n\n再次update！！！\n\n通过email和mylookout的人取得联系，说明我取得诸如设备号，手机屏幕大小是为了更智能的给设备适配图片，而获取部分的sim卡号是后来用户反馈说自己换了手机还想使用之前的收藏记录才使用的，这些信息只在该应用中使用，并没提供给任何第三方！\n\n同时让其确认venturebeat上文章中说到的获取浏览器历史，短信息，密码等高敏感性信息是否是他们说的还是写文章的人自己写的（Lots of my users send me the email ask me why I collect their text message and voicemail passward, I just want to make sure whether you and your ceo said that  I collected browsing history,text message ,voicemail passward during the meeting.）。\n\n其cto给我回复说他们没有说过我的应用获取过诸如text messages or browsing history这些信息（ We never stated that the wallpaper applications gathered users text messages or browsing history.），是媒体在撰写和传播的时候错误报道了（A member of the press misreported our research and he has since corrected it. ）。\n\n我非常无语～\n\n2010年8月4日第二次次update！\n\n多谢这些天很多朋友的关心，我很好，谢谢！这些天和google android组，lookout公司和venturebeat的作者，以及国内外很多媒体，博客们，记者们都有很多的接触。\n\n1. google就前段时间将应用暂停和我一起分析了这个应用，今天发来调查的结果：\n\nOur investigation has concluded that there's no obvious malicious code in your apps, though the implementation accesses data that it doesn't need to.  We've restored your apps (and they'll be available on Market again once you publish them), and are looking forward to seeing them updated to use ANDROID_ID.  We are likely to make a statement about this issue this week--I'll let you know.\n\n我早就说过，我配合调查，我把代码提供给他们，google也做出了公正的评判，另外也给我提了一些建议（ANDROID_ID）。\n\n2. 当时写这篇报道的venturebeat记者Dean Takahashi发来了mail，为自己犯的错误道歉，并道歉该事带来的恶劣影响，会再写一篇文章澄清这个事情以消除影响。\n\n3. 那个安全公司lookout的人写邮件来要于我一起“ We wanted to coordinate with you to prevent further misunderstandings. ”。\n\n4.好几个不认识的国外记者很负责任，发邮件和gt和我交流询问事情的真相，并帮我喊冤，谢谢这些有职业精神的记者们。\n\n这个事情到这差不多就结束了，其中看到很多假丑恶，也看到很多真善美！谢谢所有帮助过我的人（很多很多，就不一一列举）。", "created_at"=>2010-07-29 08:41:39 UTC, "updated_at"=>2012-06-24 15:35:10 UTC, "body_html"=>"

    “拉斯维加斯黑帽大会上，Lookout 的安全人员指出，一个伪装成Android手机壁纸应用的偷窃个人信息程序已经被下载了百万次，它会收集您的个人资料，并将其发送到一个来自中国深圳的神秘网站imnet.us中。安全人员(Kevin MaHaffey)估计这款程序是由正常的壁纸应用修改而来，黑客将其上传到Android Market，希望装饰自己手机的用户因此而中招。泄漏的数据包括浏览历史记录，短信，手机的SIM卡号码，用户识别号，语音邮件，甚至是密码，他警告称每个人都应该警惕来自手机上的威胁。”
    \n\n
    在看完这条消息后，我立马检查了所有代码，防止这款应用在我不知情的情况下，被他人加入恶意代码，但我一无所获。
    \n现就相关事宜申明如下：
    \n一、我开发的所有程序都没有侵犯到用户的隐私。
    \n\n
    在这个应用中，申请的全部权限为：
    \n<uses-permission android:name="android.permission.INTERNET" />
    \n<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    \n<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    \n<uses-permission android:name="android.permission.SET_WALLPAPER" />
    \n<uses-permission android:name="android.permission.READ_PHONE_STATE" />
    \n<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    \n懂点Android技术的都知道，这些权限都是为了让该软件的功能，能够正常工作所必须的权限（连接网络，获取网络状态，下载壁纸时读写SD卡，设置壁纸，读取手机状态）和Admob的广告精准推送所需要的权限（位置信息，读取手机状态）。
    \n至于获取用户浏览历史记录、短信、语音邮件密码的这些明显侵犯用户隐私的行为，完全是子虚乌有。一方面并没要申请相关的权限；另一方面我还真不知道怎样获取这些敏感信息。另外，admob的精准广告服务中可能是会针对用户的地理位置等信息推送更准确的广告服务。
    \n关于这款应用能获取的设备标识号是用来区分设备的唯一性，免去用户注册的麻烦，而能给用户提供收藏图片的功能；而诸如获取手机屏幕大小是为了能够智能适配合适的图片。在这些设备信息中，请问哪一条会侵犯到用户的隐私。
    \n另外说我可以获取浏览历史信息，这简直就是个天大的笑话。如果懂一点程序的就会知道，要获取浏览器信息必须在程序里申请com.android.browser.permission.READ_HISTORY_BOOKMARKS权限。我的程序完全没有获取到权限，怎么能够获取到历史信息，真是笑话！！！
    \n\n
    二、Android手机的权限管理，在任何没有刷过第三方rom的手机上是很严格的。
    \n Android手机的权限管理，在任何没有刷过第三方rom的手机上是很严格的，在没有相关权限的情况下，要获取那些信息，是完全不可能的。就算是被刷过Rom的手机，也只有具有该ROM制作人的加密签名的程序，才能完成一些不安全的操作。
    \n我所需要的权限在用户安装的时候会很明确的告诉用户，下面我就给大家展示一下我应用申请的权限和另外一个著名的壁纸的应用background和一款管理短信的应用申请的权限。
    \n\n
    我的软件需要的权限：
    \n\n
    看看background（另外一款壁纸的应用）申请的权限：
    \n\n
    Handcent SMS申请的权限：
    \n\n\n
    短信有短信的权限，联系人有联系人的权限，我都没要申请，请问我如何获取相关的信息。
    \n\n
    三、应用主要面向外国用户，但绝对没有获取那些高敏感度的隐私信息！
    \n\n
    该应用主要面向外国用户（国内由于网络原因无法正常使用），连接服务器端能够获取到精确适配终端的图片，这是一款非常有用，也深受用户喜爱的应用。它确实拥有数量众多（几百万）的用户，但绝对没有获取那些高敏感度的隐私信息！我每天都收到很多用户的反馈邮件告诉我这个软件多么棒，给他们带来多少乐趣！
    \n\n
    四、我本人始终与业界同仁一道，希望建立诚实守信、和谐共生的Android产业生态系统。
    \n\n
    随着Android开放性操作平台手机的广泛使用，其应用软件开发市场正呈现蓬勃发展景象。对于提醒用户警惕来自手机上的威胁，我本人向来都是强烈支持的！本人一直始终与业界同仁一道，一直为共建诚实守信、和谐共生的Android产业生态系统而努力，将力量专注于用户需求和技术创新，创造更被用户喜欢的软解，并致力于推动手机应用软件产业持续健康发展。
    \n\n
    在此，本人郑重申明，该应用没有获取任何诸如“浏览历史记录，短信，语音邮件密码等”这种高敏感度的信息，并和国外的原作者取得联系，让其修正自己的言论并发布公开道歉，同时对于这种不负责任的言论和评价观点，对我及与我相关的应用进行不负责任的报道造成的影响给予补偿，我将保留追究其法律责任的权利。
    \n\n
    ps：
    \n\n
    如果您有其他的疑问或者问题，欢迎你在我sina微博客（http://t.sina.com.cn/iceskysl）或者sohu微博（http://t.sohu.com/iceskysl）给我沟通！
    \nupdate：
    \n写完申明后，去看消息出处看到其竟然做了修改，我早料到其会做相关的行为，所有早些时候截了屏幕如下：
    \n\n\n
    而现在的文章被修改为：
    \n\n\n
    看我用鼠标标识的地方，对关键信息进行了修改，感兴趣的人可以去 http://mobile.venturebeat.com/2010/07/28/android-wallpaper-app-that-steals-your-data-was-downloaded-by-millions/ 查看原文，对于这种标题党用子虚乌有的事情炒作，等消息传播后再修改自己的内容算什么行为！而对国内部分媒体在传播时不但不对真实性进行验证，还添油加醋，歪曲意思的报道，我非常无奈（看到有人还说可以获取信用卡信息，还加密传输，我实在无语）。
    \n\n
    按照我个人的感觉，他们应该紧接着要开始拿这个事件来炒作自己的产品了，我个人懒得去关注，如果有人发现有人借此炒作自己的产品，请帮忙分析分析，看看到底是什么人用这样手法。
    \n\n
    再次update！！！
    \n\n
    通过email和mylookout的人取得联系，说明我取得诸如设备号，手机屏幕大小是为了更智能的给设备适配图片，而获取部分的sim卡号是后来用户反馈说自己换了手机还想使用之前的收藏记录才使用的，这些信息只在该应用中使用，并没提供给任何第三方！
    \n\n
    同时让其确认venturebeat上文章中说到的获取浏览器历史，短信息，密码等高敏感性信息是否是他们说的还是写文章的人自己写的（Lots of my users send me the email ask me why I collect their text message and voicemail passward, I just want to make sure whether you and your ceo said that  I collected browsing history,text message ,voicemail passward during the meeting.）。
    \n\n
    其cto给我回复说他们没有说过我的应用获取过诸如text messages or browsing history这些信息（ We never stated that the wallpaper applications gathered users text messages or browsing history.），是媒体在撰写和传播的时候错误报道了（A member of the press misreported our research and he has since corrected it. ）。
    \n\n
    我非常无语～
    \n\n
    2010年8月4日第二次次update！
    \n\n
    多谢这些天很多朋友的关心，我很好，谢谢！这些天和google android组，lookout公司和venturebeat的作者，以及国内外很多媒体，博客们，记者们都有很多的接触。
    \n\n
    1. google就前段时间将应用暂停和我一起分析了这个应用，今天发来调查的结果：
    \n\n
    Our investigation has concluded that there's no obvious malicious code in your apps, though the implementation accesses data that it doesn't need to.  We've restored your apps (and they'll be available on Market again once you publish them), and are looking forward to seeing them updated to use ANDROID_ID.  We are likely to make a statement about this issue this week--I'll let you know.
    \n\n
    我早就说过，我配合调查，我把代码提供给他们，google也做出了公正的评判，另外也给我提了一些建议（ANDROID_ID）。
    \n\n
    2. 当时写这篇报道的venturebeat记者Dean Takahashi发来了mail，为自己犯的错误道歉，并道歉该事带来的恶劣影响，会再写一篇文章澄清这个事情以消除影响。
    \n\n
    3. 那个安全公司lookout的人写邮件来要于我一起“ We wanted to coordinate with you to prevent further misunderstandings. ”。
    \n\n
    4.好几个不认识的国外记者很负责任，发邮件和gt和我交流询问事情的真相，并帮我喊冤，谢谢这些有职业精神的记者们。
    \n\n
    这个事情到这差不多就结束了，其中看到很多假丑恶，也看到很多真善美！谢谢所有帮助过我的人（很多很多，就不一一列举）。

The data can be retrieved as JSON by appending \"?json\" to the end of location on which the module was set to work on (see configuration instructions below).
    \r\n看上去正是我需要的，有时间试试看～（为啥nginx不学haproxy官方自带一个详细statistics的页面呢～haproxy那个statistics很详细很好用～）\r\n详细使用指南：http://code.google.com/p/ustats/\r\n\r\n\"\"", "created_at"=>2012-01-03 05:59:10 UTC, "updated_at"=>2012-06-24 15:35:10 UTC, "body_html"=>"

    其中upstream的这段配置：
    \nupstream unicon_v2_www {
    \n\n
    This is the socket we configured in unicorn.rb
    \n\n
    server unix:/var/www/v2/tmp/sockets/unicorn.sock backup;
    \nserver 192.168.0.1:5000 weight=9 max_fails=2 fail_timeout=30s;
    \nserver 192.168.0.2:5000 weight=3 max_fails=2 fail_timeout=30s;
    \n}
    \n\n
    我们了解到socket模式的这个是backup，其他两个机器分别weight=3和weight=9,于是我们想监控下upstream每个后端具体处理了多少请求，有没有问题等，这个好像就不好监控了，nginx自带的status模块只能监控总的请求数，无法区分每个upstream的具体情况。
    \n找到一个ustats（http://code.google.com/p/ustats/），其介绍是：NGINX basic upstream statistics module，具体的如下：<!--more-->
    \nUSTATS module provides basic statistics for each backend in nginx upstreams:
    \n\n
    Number of requests
    \nHttp 499/500/503 errors count
    \nTcp errors
    \nHttp read/write timeouts
    \nFail timeout
    \nMax fails count
    \nLast failed access time
    \nTotal fails count
    \nBlacklisted backend highlighting
    \nDown backends highlighting
    \nThe module allows you to sort values in some columns for each separate upstream. The data can be retrieved as JSON by appending "?json" to the end of location on which the module was set to work on (see configuration instructions below).
    \n看上去正是我需要的，有时间试试看～（为啥nginx不学haproxy官方自带一个详细statistics的页面呢～haproxy那个statistics很详细很好用～）
    \n详细使用指南：http://code.google.com/p/ustats/

    \n2. 需要支持子任务（最好是不限制级的，目前能用到3级别）
    \n3. 界面简洁，再简洁
    \n4. 支持多端访问，至少在电脑和手机（android&iphone)可以使用
    \n5. 可以打印或者email给朋友
    \n\n
    最终还是回到了Google Task，经过一段时间的使用，我现在已经非常喜欢Google Task，也给我的效率带来很大帮助，我可以把我的方式分享下。
    \n1. 每天开电脑的第一件事情就是开gmail，处理完邮件开始工作，顺手把gmail里把Google Task打开，并pop up出一个单独的窗口，拖拉到合适的大小；（我工作的时候是两个显示器，就把这个窗口一直放在外接显示器的边上，抬眼可见）
    \n2. 每周一个list，名字是时间范围，比如2012.02.06－2012.02.12；
    \n3. 周一的时候会尽量把本周要做的事情列进去（按照事情的类型或者项目，比如公司事务，eoemarket相关），再把要做的事情一个一个输入进去，Google Task的输入很方便，用好tab键和shift tab键来调整层级；用好Ctrl + Up和Ctrl + Down来调整顺序，用Shift + Enter进入到具体的事情中撰写详细，写完再Shift + Enter回到列表；
    \n4. 每次做事情的时候，可以用Tab再细分，一个一个执行掉；完成后回到Google Task，用Option + Enter 标识这个完成（Option + Enter这个快捷键在官方帮助文档和tips里都没，我自己找出来的，mac电脑）；另外勾选上级条目可以把下级条目都标记完成～
    \n5. 每次遇到新的事情直接添加进去，经常review，如此反复就好了～
    \n6. 有的时候还通过打印和发送邮件通知其他人我都做了什么；
    \n\n
    此外，Google Task提供如下方式的使用，我个人觉得足够了
    \n1. gmail中集成/igoogle集成
    \n2. iphone客户端，android客户端（第三方开发的）
    \n3. chrome插件
    \n4. 桌面客户端（没找到，也不怎么用）
    \n5. api接口（或者自己写）
    \n\n
    如果硬说还可以有些期待的话，我的是这样的：
    \n1. 谁写个更好用的iphone客户端（现在app store上的质量一般，而且收费，哪天我心血来潮我来写一个去～）
    \n2. 可以把一个list里没完成的复制到另外一个list中
    \n3. 真木了
    \n\n
    我的个人建议是：必须用好快捷键！
    \n\n
    希望我的这篇介绍能让你喜欢Google Task，并对自己有所帮助

    Those of us running Ruby 1.8.4 or earlier must upgrade to 1.8.5 or later for a fix. Those on 1.8.5-7 can grab the latest patchlevel release for a fix.
    \n\n
    (Please note: Ruby 1.8.7 breaks backward compatibility and is only compatible with Rails 2.1 and later, so don’t go overboard!)
    \n虽然暂时还没看到具体的细节公布出来，也没看到0day放出来，但是从其描述上不难看出，这些bug是ruby一致以来都有的，或许还有更多的bug，ruby走向成熟，离不开这样的检验。

    现在很多人应该都开始使用Rails2.1了吧，如果你还没有升级到Rails2.1版，那么看看前段时间，我和其他几个RoRer翻译的《Rails 2.1中文文档翻译完成[已发布]》中其所增加的新功能。如果这些新功能还不能说服你升级到Rails2.1的话，那么请接着看，在Rails2.1之前，Rails1.X和Rails2.0中都存在如下漏洞。

    大家可以看看Rails2.1之前的 ActiveRecord 中，其允许在:offset中任意构造SQL语句，也就是说，如果可能的话，我们可以利用:offset来构造SQL注射。

    \n\n
    总的来看，有两个方式来实现对WML的支持，单独支持和整合支持，下面详细的说。
    \n\n
    一、按照一般方式支持
    \n\n
    这个方式和做PC WEB方式是一样的，有个单独的controller或者action，指定特有的layout和页面模板，而这些模板中采用WML语言编写，在请求到来的时候，按照URL中特有的特征字符（比如二级域名）或者Http Head中的标识转向Wap的action，进而显示。详细的步骤基本上是这样的：
    \n\n
    1、在app/controllers/application.rb中增加对WAP格式输出的支持
    \n
    \nRuby代码
    \n
    \n    before_filter :set_wap_content_type, :only => :wap  
    \n      
    \n    def set_wap_content_type  
    \n      @headers["Content-Type"] = “text/vnd.wap.wml; charset=iso-8859-1″  
    \n    end  
    \n
    \n
    \n2、添加一个WAP的全局布局模板app/views/layouts/wap.rhtm
    \n
    \nXML/HTML代码
    \n
    \n    <?xml version=”1.0″?>  
    \n    <!DOCTYPE wml PUBLIC “-//WAPFORUM//DTD WML 1.1//EN” “http://www.wapforum.org/DTD/wml_1.1.xml”>  
    \n    <wml>  
    \n    <card title=”<%= @title %>”>  
    \n    <p align=”center”>  
    \n    <%= @content_for_layout %>  
    \n    </p>  
    \n    </card>  
    \n    </wml>  
    \n
    \n
    \n3、在我的controller中（index）中增加一个action用来响应WAP请求。
    \n
    \nRuby代码
    \n
    \n    def wap  
    \n      @title = "San Francisco Sailing Weather"  
    \n      render(:layout => "wml")  
    \n    end  
    \n
    \n
    \n4、添加相应的view模板app/views/index/wap.rhtml
    \n
    \nXML/HTML代码
    \n
    \n    <%= link_to 'NOAA Marine Forecast', { :controller => '/marine/forecast', :action => 'wap' } %><br/>  
    \n    <%= link_to 'Wind Readings', { :controller => '/marine/wind', :action => 'wap' } %><br/>  
    \n    <%= link_to 'Current Predictions', { :controller => '/marine/tide', :action => 'wap' } %>  
    \n
    \n
    \n 
    \n\n
    二、使用Rails2支持的多模板类型支持
    \n\n
    在Rails2以后，Rails支持多种格式的输出，比如Html，RSS，JS等，当然你还可以定制自己的格式，比如我们这里说的WML，Iphone等，使用起来更简单、自然。
    \n\n
    1、添加MIME格式支持
    \n\n
    在config/environment.rb中增加MIME的格式支持，方式如下：
    \n
    \nRuby代码
    \n
    \n    Mime::Type.register "text/vnd.wap.wml", :wml  
    \n
    \n
    \n
    \n2、判断请求类型
    \n<div class="codeText">
    \n<div class="codeHead">Ruby代码</div>
    \n<ol class="dp-rb" start="1">
    \n    <li class="alt"><span><span class="comment"># application.rb</span><span>  </span></span></li>

    \n    <li><span><span class="keyword">end</span><span>  </span></span></li>
    \n</ol>
    \n</div>
    \n<pre style="font-size: 90%;">
    \n<strong>3、添加相应的view代码</strong>比较简单，就是写XML或者WML模板<strong>show.wml.erb</strong>
    \n
    \nXML/HTML代码
    \n
    \n    xml.instruct! :xml, :version => "1.0"  
    \n    xml.wml "xml:lang" => "en-gb" do  
    \n      xml.card :title => "My title here" do  
    \n        xml.p "Something interesting here"  
    \n        xml.p "Something else interesting here."  
    \n      end  
    \n    end  
    \n
    \n
    \n
    \n4、添加输出类型支持
    \n<div class="codeText">
    \n<div class="codeHead">Ruby代码</div>
    \n<ol class="dp-rb" start="1">
    \n    <li class="alt"><span><span class="keyword">def</span><span> index  </span></span></li>

    1. General options:  
      2. \r\n\t
    2.   
      3. \r\n\t
    3. -h or --help  
      4. \r\n\t
    4.     Print quick or full usage details respectively.  
      5. \r\n\t
    5. -r or --recursive  
      6. \r\n\t
    6.     Search directory arguments recursively for files to convert.  
      7. \r\n\t
    7. -d or --delete  
      8. \r\n\t
    8.     delete input files after successful conversion. May not be safe yet!!!  
      9. \r\n\t
    9. -v or --verbose  
      10. \r\n\t
    10.     makes sneetchalizer more chatty.  
      11. \r\n\t
    11. -s or --show-output  
      12. \r\n\t
    12.     shows output from conversion tool.  
      13. \r\n\t
    13. -p or --pretend  
      14. \r\n\t
    14.     don't convert anything. sneetchalizer will go through the motions and print out the commands it would run. Useful for preview- ing a complex command line to ensure it does what you intend. You should interpret this option's output with a grain of salt. For example, if you include the '--sanitize' option, the files will not really be renamed when using --pretend, and as such the command's output will not reflect that the filenames would be changed during an actual run.  
      15. \r\n\t
    15. -t or --terminate  
      16. \r\n\t
    16.     terminate sneetchalizer options. This is useful if you have to convert '--coolDir' or '-groovySong.mp3'. This is the only option whose order on the command line is significant.  
      17. \r\n\t
    17. -D ARG or --out-directory=ARG  
      18. \r\n\t
    18.     write all outfiles to a directory argument. This is useful if you want to (re)encode files directly to a mounted portable device.  
      19. \r\n\t
    19. --strict and --pedantic  
      20. \r\n\t
    20.     many errors that sneetchalizer may encounter are recoverable, such as specifying a directory as argument that contains no files to convert, or conversion failures in general. By default the script will print an error message and move on to the next file. If you use '--strict' then sneetchalizer will bail out at the first sign of trouble except for tag errors. With '--pedantic' the script will stop even on tag errors.   
      21. \r\n\t
    21. --stasis  
      22. \r\n\t
    22.     Preserve timestamp (mtime) of original file.  
      23. \r\n\t
    23. --threads [N]  
      24. \r\n\t
    24.     Experimental. Use threads to create concurrent jobs. This option takes an optional integer argument which represents the number of threads to launch. The default is two. Preliminary tests suggest there is little advantage (and even diminishing returns) when setting this number greater than the number of cores/CPUs you have. Due to the asychronous nature of threads the --verbose and --show-output flags will be silently disabled and most screen output is supressed.   
      25. \r\n\t
    25. --sanitize  
      26. \r\n\t
    26.     Removes ,, ;, :, ', \", %, @, #, and ` from filenames and tags.  
      27. \r\n\t
    27. -n [FORMAT] or --rename[=FORMAT]  
      28. \r\n\t
    28.     rename all outfiles (and temporary wavs) according to FORMAT. FORMAT is a string with special designators to be pulled from the file tags. The following options are available:

    \r\n
    使用示例：
    \r\n
      \r\n\t
    1. $ sneetchalizer song.mp3  
      2. \r\n\t
    2.   
      3. \r\n\t
    3. The most simple possible example, creates 'song.wav'.  
      4. \r\n\t
    4.   
      5. \r\n\t
    5. $ sneetchalizer --out=ogg --in=flac -q5 /some/music/dir  
      6. \r\n\t
    6.   
      7. \r\n\t
    7. This example converts every flac file in '/some/music/dir' to ogg format at quality 5.  
      8. \r\n\t
    8.   
      9. \r\n\t
    9. $ sneetchalizer -d --out=mp3 --in=ogg,m4a,wma -b 160 .  
      10. \r\n\t
    10.   
      11. \r\n\t
    11. Converts every ogg, m4a, and wma file in the current directory to a 160 kbps constant bitrate mp3 file. The original files are deleted.  
      12. \r\n\t
    12.   
      13. \r\n\t
    13. $ sneetchalizer --out=mp3 --out-optionhook=\"--preset extreme\" /some/wavs  
      14. \r\n\t
    14.   
      15. \r\n\t
    15. Here we encode every wav in '/some/wavs' to mp3 format passing '--preset extreme' directly to lame.  
      16. \r\n\t
    16.   
      17. \r\n\t
    17. $ sneetchalizer --in=ogg --out=ogg --quality=1 norvegianWood.ogg /some/more/oggs  
      18. \r\n\t
    18.   
      19. \r\n\t
    19. Using the same --in and --out format allows us to resample/encode the file at a different bitrate or quality. Note that this will overwrite the original file so only do this on a copy, or use '-D' to write files to another directory.  
      20. \r\n\t
    20.   
      21. \r\n\t
    21. $ sneetchalizer --in=ogg --out=m4a -D /mnt/ipod/ /some/oggs  
      22. \r\n\t
    22.   
      23. \r\n\t
    23. Here we re-encode some ogg files to m4a format and write them to our mounted iPod.

    \r\n4、注意事项\r\n\r\n本脚本只是粘合剂，其他的tool还是需要另外安装的。\r\n\r\n其他信息请参考其主页说明,如果您有这个方面的问题或经验，欢迎和我讨论。\r\n\r\n\r\n\r\n\r\n ", "created_at"=>2008-10-09 02:49:27 UTC, "updated_at"=>2012-06-24 15:43:51 UTC, "body_html"=>"
    前几天写了“采用Ruby提取MP3的metadata信息”后，就在寻找成熟的Ruby代码做差不多的事情，今天找到一个sneetchalizer，仔细的看了下，非常强大。
    \n\n\n
    sneetchalizer其实只是个粘合剂，因为在*unix下，audio格式转换的lib已经非常丰富和成熟，例如lame,gogo,bladeenc,mplayer等等就非常好用；另外，关于audio的tag信息和metadata信息的提取也有比较成熟的lib了，类似id3lib-ruby library,wmainfo-rb library,ruby-ogginfo library等等。而sneetchalizer只是把这些tools粘合起来。
    \n\n
    其支持的格式有:'aac' 'aif' 'aifc' 'aiff' 'aiffc' 'ape' 'au' 'caf' 'cdda' 'cdr' 'copy' 'fap' 'flac' 'gsm''ircam' 'm4a' 'm4b' 'mat' 'mat4' 'mat5' 'mp2' 'mp3' 'mp4' 'mpc' 'mpp' 'nist' 'ofr''ofs' 'ogg' 'paf' 'pvf' 'raw' 'sd2' 'sds' 'sf' 'snd' 'spx' 'svx' 'tta' 'voc''vox' 'w64' 'wav' 'wma' 'wv' 'xi'
    \n\n
    使用sneetchalizer可以实现audio文件的格式转换和tag信息提取和写入，详细使用方法参考其主页上说明，下面简要的说说起安装方法和使用参数：
    \n\n
    1、安装方法
    \n\n
    直接下载其gz包，sneetchalizer-0.9.0是现在的最新版本。下载解包后可以看到：
    \n
    \nManifest:
    \n
    \n    README                - You're reading it now.  
    \n    LICENSE               - A copy of the GPL, under which sneetchalizer is released.  
    \n    CHANGES               - sneetchalizer's cvs/svn commit log.  
    \n    sneetchalizer         - The script itself.  
    \n    sneetchalizer.1       - The manpage for sneetchalizer.  
    \n    sneetchalizer.desktop - A KDE service menu for converting with Konqueror.  
    \n    install.rb            - A quick and dirty script to install the sneetchalizer.  
    \n
    \n
    \n如果有root权限，可以直接运行install.rb，其会将sneetchalizer拷贝到/usr/bin下，将sneetchalizer.1拷贝到/usr/share/man/man1下。
    \n\n
    2、参数解释
    \n\n
    不翻译了，都挺简单明了的，如下：
    \n
    \nXML/HTML代码
    \n
    \n    General options:  
    \n      
    \n    -h or --help  
    \n        Print quick or full usage details respectively.  
    \n    -r or --recursive  
    \n        Search directory arguments recursively for files to convert.  
    \n    -d or --delete  
    \n        delete input files after successful conversion. May not be safe yet!!!  
    \n    -v or --verbose  
    \n        makes sneetchalizer more chatty.  
    \n    -s or --show-output  
    \n        shows output from conversion tool.  
    \n    -p or --pretend  
    \n        don't convert anything. sneetchalizer will go through the motions and print out the commands it would run. Useful for preview- ing a complex command line to ensure it does what you intend. You should interpret this option's output with a grain of salt. For example, if you include the '--sanitize' option, the files will not really be renamed when using --pretend, and as such the command's output will not reflect that the filenames would be changed during an actual run.  
    \n    -t or --terminate  
    \n        terminate sneetchalizer options. This is useful if you have to convert '--coolDir' or '-groovySong.mp3'. This is the only option whose order on the command line is significant.  
    \n    -D ARG or --out-directory=ARG  
    \n        write all outfiles to a directory argument. This is useful if you want to (re)encode files directly to a mounted portable device.  
    \n    --strict and --pedantic  
    \n        many errors that sneetchalizer may encounter are recoverable, such as specifying a directory as argument that contains no files to convert, or conversion failures in general. By default the script will print an error message and move on to the next file. If you use '--strict' then sneetchalizer will bail out at the first sign of trouble except for tag errors. With '--pedantic' the script will stop even on tag errors.   
    \n    --stasis  
    \n        Preserve timestamp (mtime) of original file.  
    \n    --threads [N]  
    \n        Experimental. Use threads to create concurrent jobs. This option takes an optional integer argument which represents the number of threads to launch. The default is two. Preliminary tests suggest there is little advantage (and even diminishing returns) when setting this number greater than the number of cores/CPUs you have. Due to the asychronous nature of threads the --verbose and --show-output flags will be silently disabled and most screen output is supressed.   
    \n    --sanitize  
    \n        Removes ,, ;, :, ', ", %, @, #, and ` from filenames and tags.  
    \n    -n [FORMAT] or --rename[=FORMAT]  
    \n        rename all outfiles (and temporary wavs) according to FORMAT. FORMAT is a string with special designators to be pulled from the file tags. The following options are available:  
    \n      
    \n            * %t Song title  
    \n            * %b Album title  
    \n            * %n Track number  
    \n            * %a Artist name  
    \n            * %y Year  
    \n            * %g Genre  
    \n            * %c Comment field  
    \n      
    \n        Directories may be created with this command, as in "%b/%n - %t". The default value of FORMAT is "%n %t".   
    \n      
    \n    Bitrate/Quality/Compression options:  
    \n      
    \n    -b or --bitrate  
    \n        mp3/ogg/m4a bitrate.  
    \n    -q or --quality  
    \n        mp3/ogg quality.  
    \n      
    \n    quality and bitrate are passed directly to lame or oggenc depending on mp3 or ogg output format respectively. Both tools can handle either a bitrate or quality argument, so it is important to understand what values are valid for the underlying tool in your specific use case. faac will accept a bitrate argument, but not a quality argument. These options will be silently ignored for any output formats other than mp3, ogg or m4a. Make sure you know what you are doing if you decide to use both in one run, and read each tools manpage for valid values. If these options are omitted the tools builtin defaults are used (-q3 for oggenc and -q5 for lame).  
    \n      
    \n    -c or --compression  
    \n        flac/mac compression level.  
    \n      
    \n    this option allows you to pass a compression argument to flac and mac. See 'flac --help' and/or 'mac --help' if you don't know what this means.  
    \n      
    \n    Format Options:  
    \n      
    \n    --out=format  
    \n        output format. Default is wav.  
    \n    --in=format[,format..]  
    \n        input format(s). Default is wav.  
    \n      
    \n    Valid output formats are: "aac", "aif", "aifc", "aiff", "aiffc", "ape", "au", "cdr", "cdda", "copy", "flac", "m4a", "m4b", "mpc", "mp4", "mpp", "mp3", "mp2", "ofr", "ofs", "ogg", "snd", "spx", "tta", "wav", "wv". Valid input formats are all of the above plus "wma". You can specify multiple input formats using a comma: 'mp3,m4a,wma'. Input format is only neccesary when passing directory arguments, as file arguments are handled by context (read: file extension). The "copy" output option copies files directly, bypassing decoding/encoding steps (useful in conjunction with --rename).  
    \n      
    \n    Tagging Options:  
    \n      
    \n    --tt or --title  
    \n        Set 'title' tag.  
    \n    --ta or --artist  
    \n        Set 'artist' tag.

    \n    $ sneetchalizer -d --out=mp3 --in=ogg,m4a,wma -b 160 .  
    \n      
    \n    Converts every ogg, m4a, and wma file in the current directory to a 160 kbps constant bitrate mp3 file. The original files are deleted.  
    \n      
    \n    $ sneetchalizer --out=mp3 --out-optionhook="--preset extreme" /some/wavs  
    \n      
    \n    Here we encode every wav in '/some/wavs' to mp3 format passing '--preset extreme' directly to lame.  
    \n      
    \n    $ sneetchalizer --in=ogg --out=ogg --quality=1 norvegianWood.ogg /some/more/oggs  
    \n      
    \n    Using the same --in and --out format allows us to resample/encode the file at a different bitrate or quality. Note that this will overwrite the original file so only do this on a copy, or use '-D' to write files to another directory.  
    \n      
    \n    $ sneetchalizer --in=ogg --out=m4a -D /mnt/ipod/ /some/oggs  
    \n      
    \n    Here we re-encode some ogg files to m4a format and write them to our mounted iPod.

    生产环境下，需要对环境持续监控以尽快的发现问题，找到耗费资源较多的地方加以改进，比较常见的做法是使用moint或者God实时监控；另外，还可以定期分析日志找到特定的请求，虽然可以是shell来做这件事，但是何必再造轮子呢，因为我们已经有了Request log analyzer ：
    \n``简介：This is a simple command line tool to analyze request log files of both Rails andMerb. Its purpose is to find what actions are best candidates for optimization.This tool will parse all requests in the logfile and aggregate theinformation. Once it is finished parsing the log file, it will show therequests that take op most server time. Different metrics are used (cumulativetime, average time, blockers, DB time, etc)

    Ruby可以很方便的解析XML格式的文档，目前用的比较多的lib主要有三个，分别是：REXML, Hpricot, libxml-ruby，如下选取两个XML文档，分别使用这三个lib解析，感受下各自的速度和易用性。
    \n一、原料
    \n
    \n    posts.xml – Uses xml element for object (post) and xml attributes for object attributes
    \n    timeline.xml – Uses xml element for object (status) and child xml elements for attributes
    \n
    \n二、解析过程
    \n1、REXML
    \n\n
    Pros: In the standard library
    \nCons: Slow, I don’t like the name

    在Android中使用GoogleMap非常方便，但是有些小技巧或者注意事项你必须牢记，否则调试半天你也不会找到啥线索，浪费时间不说，更让你狂抓，以下技巧都是我在实际项目中遇到的，不断更新和维护，如果你有类似技巧，欢迎分享：
    \n
    （以下技巧是基于SDK 1.0的）
    \n
    一、申请Apikey，并放在正确的位置
    \n
    这个应该都知道，但是是申请得到的key放哪里很多人不知道，可以放在
    \n
    1、XML布局文件中
    \n
    <view android:id="@+id/mv"
    \n   class="com.google.android.maps.MapView"
    \n   android:layout_width="fill_parent"
    \n   android:layout_height="fill_parent"
    \n   android:layout_weight="1" 
    \n   android:apiKey="01Yu9W3X3vbpYT3x33chPXXX7U1Z6jy8WYZXNFA" 
    \n   />
    \n
    2、java中
    \n
            mMapView = new MapView(this, "01Yu9W3X3vbpYT3x33chPxxx7U1Z6jy8WYZXNFA");
    \n
    二、记得导入uses-library 
    \n
     由于1.0版本的修改，使得map包不再是默认的了，使用的时候需要在manifest中的application节点下加入
    \n
    <uses-library android:name="com.google.android.maps" /> 
    \n
    \n
    否则，你将遇到可恶的“java.lang.NoClassDefFoundError: ”，切记！
    \n
    三、需要给予一定的权限
    \n
    因为要使用GoogleMAP的service，所以需要
    \n<uses-permission android:name="android.permission.INTERNET"></uses-permission>
    \n
    如果需要GPS等应用，还需要
    \n
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
    \n
    四、Activity需要继承自MapActivity
    \n
    类似如下代码；
    \n
    package com.iceskysl.showmap;
    \n
    \nimport com.google.android.maps.MapActivity;
    \n
    \nimport android.os.Bundle;
    \n
    \npublic class ShowMap extends MapActivity {
    \n    /** Called when the activity is first created. */
    \n    @Override
    \n    public void onCreate(Bundle savedInstanceState) {
    \n        super.onCreate(savedInstanceState);
    \n        setContentView(R.layout.main);
    \n    }
    \n
    \n    @Override
    \n    protected boolean isRouteDisplayed() {
    \n        // TODO Auto-generated method stub
    \n        return false;
    \n    }
    \n}

  • Use Sphinx for text search.  --sometimes,you do have others chose.
    • \n
  • Use InnoDB for more crash resistant and faster writes.  --maybe it's right.
    • \n
  • Don't use textbook Rails ActiveRecord objects. Use New Relic to find exactly what is slow in your system. --yep
    • \n
  • Use memcache later so you find your database bottlenecks now. --this is very important.
    • \n
  • Use mongrel proctitle to find your slow queries. You are only as fast as your slowest queries. -maybe mongrel is not only chose,think about thin,ok?
    • \n
  • Use asynchronous job queuing to do work in parallel.  --yes,but sometimes crontab is enough.
    • \n
  • Use monitoring so you'll know when your site went down and why. --that's it,just do it.
    • \n
  • Learn by reading the source code, fixing problems, and submitting them back to the community.  --very userfull when you got some strange questions..
    • \n
  • Use new plugins. Old plugins can't be trusted. --and check chang histroy carefully.

    I konw,you can dev app and test it on the simulator,but if you had a real driver,G1,you can do debug on it,very great,here is the tips for this:\n
      \n    
    1. On your G1, go to Settings \"Arrow\" Applications \"Arrow\" Development \"Arrow\" [X] USB debugging 
      2. \n    
    2. Download this file: android_usb_windows.zip 
      3. \n    
    3. Unzip it to a folder 
      4. \n    
    4. Connect your G1 with your PC 
      5. \n    
    5. When it asks for driver location choose the unzipped folder and install the driver for it.
      6. \n    
    6. You'll see sth like "HTC Dream Composite ADB Interface" on success 
      7. \n    
    7. (Re)Start Eclipse 
      8. \n    
    8. Your G1 should now be listed in the DDMS-Perspective under Devices 
      9. \n    
    9. Go to the AndroidManifest.xml of your App and modify it to contain android:debuggable="true" in the <application ... >-Tag ,look like this:<application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="true">
      10. \n    
    10. Go Debug as usual.

    I konw,you can dev app and test it on the simulator,but if you had a real driver,G1,you can do debug on it,very great,here is the tips for this:
    \n
    \n    On your G1, go to Settings  Applications  Development  [X] USB debugging 
    \n    Download this file: android_usb_windows.zip 
    \n    Unzip it to a folder 
    \n    Connect your G1 with your PC 
    \n    When it asks for driver location choose the unzipped folder and install the driver for it.
    \n    You'll see sth like "HTC Dream Composite ADB Interface" on success 
    \n    (Re)Start Eclipse 
    \n    Your G1 should now be listed in the DDMS-Perspective under Devices 
    \n    Go to the AndroidManifest.xml of your App and modify it to contain android:debuggable="true" in the <application ... >-Tag ,look like this:<application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="true">
    \n    Go Debug as usual.

    \n1.DYNAMICALLY LOADING CONFIG FILES INTO AN ALREADY RUNNING GOD
    \n
    \n
    God allows you to load or reload configurations into an already running instance. There are a few things to consider when doing this:
    \n
      \n    
    • Existng Watches with the same name``` as the incoming Watches will be overidden by the new config.
      • \n    
    • All paths must be either absolute or relative to the path from which god was started.
      • \n
    \n
    To load a config into a running god, issue the following command:
    \n
    $ sudo god load path/to/config.god
    # god load /data/www/api/config/config_thin_api.god```\n
    Config files that are loaded dynamically can contain anything that a normal config file contains, however, global options such as God.pid_file_directory``` blocks will be ignored (and produce a warning in the logs).

    《Google API大全：编程·开发·实例》这本书是国内的第一本较为完整的介绍Google API的书，内容囊括了所有主要的Google API，并用大量的实例展示了Google API的应用方法。想更快的了解这些强大的API，本书无疑是个很好的枕边书。

    wow，千万级的，看来够大，这个没啥用，先备份下数据文件，然后truncate掉

    \n
    \n
    出错了，这边表貌似被MERGE用了，查了一下，果然是被rails_logs这个表MERGE着用了，那我直接truncate这个rails_logs试试看。
    \n
    mysql> truncate table  rails_logs;
    \n
    ERROR 1 (HY000): Can't create/write to file './iceskysl_beta_log/rails_logs.MRG' (Errcode: 17)
    \n
    \n
    呀，还是出错，文件不可写？Errcode: 17
    \n
    查下资料，原来：
    \n
    System error: 17 = File exists
    \n
    \n
    这咋回事，再查资料，原来.MRG是创建MERGE表的时候创建的，已经存在了。
    \n
    \n
    那就先把这个MERGE表干掉，再创建：
    \n
    先看下这个表是咋定义的：
    \n
    mysql>  show create table rails_logs;
    \n
    \n
    记录下SQL，接着drop掉。
    \n
    mysql> DROP  table rails_logs;
    \n
    Query OK, 0 rows affected (0.36 sec)
    \n
    \n
    再truncate我的目标表
    \n
    mysql> truncate table  rails_logs_081023;
    \n
    Query OK, 0 rows affected (4.22 sec)
    \n
    \n
    \n
    够快的，11042292条数据4S搞定，接着再创建下这个MERGE表，执行下上面记录的SQL就好了。
    \n
    \n
    最后确认下这表没啥问题：
    \n
    \n
    mysql> select count(id) from rails_logs;
    \n
    +-----------+
    \n
    | count(id) |

    \n
    +-----------+
    \n
    1 row in set (0.00 sec)
    \n
    \n
    OK，搞定，空间有了，天下太平了。

    \n
    问题：有一个拥有1亿条数据的表，只需要保留其中的5条，其他删除，如何做？
    \n
    这就需要用truncate table来搞定了，如下：
    \n
    select 5条数据 into #临时表 from 1亿条数据的牛X表
    \n
    truncate table 1亿条数据的牛X表
    \n
    --让它牛X，不到10毫秒干掉它。

    drop table #临时表

    然后有过了不记得多少时间，用了一个杭州的3G联通的卡，在G1手机上，没感觉啥时3G，只是相同资费，多点流量的感觉。
    \n\n
    然后再过了记不清多少时间，我自己在深圳电信营业厅买了一个电信3G无线上网卡，为啥选电信，也是大致比较了下3家，无疑这款不分漫游，不限流量按时间计费的无线网卡适合我的需求，只是电信的无线数据终端贵的离谱（好像也是市场价），淘宝了一个华为EC1261的，便宜不少，顺风送的，很快，第二天早上就送到了。
    \n\n
    插卡，连USB，测试，很顺利，本来比较担心mac下支持的不好，还好只碰到了“找不到设备”，Google一把，又乱找了一通，找到一个设置的地方，新建一个连接，号码#777,密码用户名card（都默认填写好了），点击连接就连上了。
    \n\n
    关了wifi，测试速度，比我预想的要好，参考图：
    \n\n\n
    下了一个100M的东西，花了7分多，速度在200K之上，还比较稳定，如下

    \n\n
    然后在测试下我本地wifi（电信4M带宽）速度，惨不忍睹，如下

    \n\n
    竟然不如无线上网卡的速度～
    \n\n
    用上无线上网卡，应该算进入3G时代了。
    \n\n
    PS：
    \n唯一不满意的地方就是这个无线网卡的设备有点大，我mac就2USB，被他占了一个后，另外一个耶盖住一点点，鼠标的USB插不进去了，难道还要买个USB分线器，冏～

    Example MySQL config file for large systems.
    \n\n
    This is for a large system with memory = 512M where the system runs mainly
    \n\n
    MySQL.
    \n\n
    You can copy this file to
    \n\n
    /etc/my.cnf to set global options,
    \n\n
    mysql-data-dir/my.cnf to set server-specific options (in this
    \n\n
    installation this directory is /var/lib/mysql) or
    \n\n
    ~/.my.cnf to set user-specific options.
    \n\n
    In this file, you can use all long options that a program supports.
    \n\n
    If you want to know which options a program supports, run the program
    \n\n
    with the "--help" option.
    \n\n
    The following options will be passed to all MySQL clients
    \n\n
    [client]
    \nport            = 3306
    \nsocket          = /var/lib/mysql/mysql.sock

    By default, the wait_timeout value is 28800. Unless you want MySQL to keep waiting for 28800 seconds (480 minutes or 8 hours),
    \n\n
    please decrease its value according to your application needs.

    Don't listen on a TCP/IP port at all. This can be a security enhancement,
    \n\n
    if all processes that need to connect to mysqld run on the same host.
    \n\n
    All interaction with mysqld must be made via Unix sockets or named pipes.

    \n新风格：让人眼前一亮的涂鸦风格，很能还原手绘效果；
    \n可中文：在菜单栏 View 里将 Use System Fonts 勾上，就能完美支持中文输入（注：非 Balsamiq Mockups 中文版）；
    \n其它点：Balsamiq Mockups 使用 xml 记录，方便移植、二次利用；可导出为 png 格式图片。
    \n\n
    另外还有跨平台与多版本两个优点：
    \n跨平台：Balsamiq Mockups 基于 Air ，因此能同时在 Windows、Mac OS 及 Linux 下使用；
    \n多版本：包括桌面版本，以及集成于 Confluence、JIRA、XWiki、FogBugz 中的版本

    配置
    \n\n
    那么应该怎样来配置成我喜欢的颜色呢？下面我们就来详细说一些这些配置。
    \n\n
    ~/.bash_profile是bash shell中当前登录用户的配置文件。bash是“终端”中默认的shell。
    \n\n
    alias ls=”ls -G”是给”ls -G”起了一个别名，当执行ls时，就相当于执行了ls -G。
    \n\n
    CLICOLOR是用来设置是否进行颜色的显示。CLI是Command Line Interface的缩写。
    \nLSCOLORS是用来设置当CLICOLOR被启用后，各种文件类型的颜色。LSCOLORS的值中每两个字母为一组，分别设置某个文件类型的文字颜色和背景颜色。LSCOLORS中一共11组颜色设置，按照先后顺序，分别对以下的文件类型进行设置：
    \n\n
    directory
    \nsymbolic link
    \nsocket
    \npipe
    \nexecutable
    \nblock special
    \ncharacter special
    \nexecutable with setuid bit set
    \nexecutable with setgid bit set
    \ndirectory writable to others, with sticky bit
    \ndirectory writable to others, without sticky bit
    \nLSCOLORS中，字母代表的颜色如下：
    \n\n
    a 黑色
    \nb 红色
    \nc 绿色
    \nd 棕色
    \ne 蓝色
    \nf 洋红色
    \ng 青色
    \nh 浅灰色
    \nA 黑色粗体
    \nB 红色粗体
    \nC 绿色粗体
    \nD 棕色粗体
    \nE 蓝色粗体
    \nF 洋红色粗体
    \nG 青色粗体
    \nH 浅灰色粗体
    \nx 系统默认颜色
    \n所以，如果我们想把目录显示成红色，就可以把LSCOLORS设置为bxfxaxdxcxegedabagacad就可以了

    现就相关事宜申明如下：
    \n一、我开发的所有程序都没有侵犯到用户的隐私。\n\n在这个应用中，申请的全部权限为：\n
    <uses-permission android:name=\"android.permission.INTERNET\" />
    \n
    <uses-permission android:name=\"android.permission.ACCESS_NETWORK_STATE\" />
    \n
    <uses-permission android:name=\"android.permission.WRITE_EXTERNAL_STORAGE\" />

    <uses-permission android:name=\"android.permission.READ_PHONE_STATE\" />
    \n
    <uses-permission android:name=\"android.permission.ACCESS_COARSE_LOCATION\" />
    \n懂点Android技术的都知道，这些权限都是为了让该软件的功能，能够正常工作所必须的权限（连接网络，获取网络状态，下载壁纸时读写SD卡，设置壁纸，读取手机状态）和Admob的广告精准推送所需要的权限（位置信息，读取手机状态）。\n至于获取用户浏览历史记录、短信、语音邮件密码的这些明显侵犯用户隐私的行为，完全是子虚乌有。一方面并没要申请相关的权限；另一方面我还真不知道怎样获取这些敏感信息。另外，admob的精准广告服务中可能是会针对用户的地理位置等信息推送更准确的广告服务。\n关于这款应用能获取的设备标识号是用来区分设备的唯一性，免去用户注册的麻烦，而能给用户提供收藏图片的功能；而诸如获取手机屏幕大小是为了能够智能适配合适的图片。在这些设备信息中，请问哪一条会侵犯到用户的隐私。\n另外说我可以获取浏览历史信息，这简直就是个天大的笑话。如果懂一点程序的就会知道，要获取浏览器信息必须在程序里申请com.android.browser.permission.READ_HISTORY_BOOKMARKS权限。我的程序完全没有获取到权限，怎么能够获取到历史信息，真是笑话！！！\n\n二、Android手机的权限管理，在任何没有刷过第三方rom的手机上是很严格的。\n Android手机的权限管理，在任何没有刷过第三方rom的手机上是很严格的，在没有相关权限的情况下，要获取那些信息，是完全不可能的。就算是被刷过Rom的手机，也只有具有该ROM制作人的加密签名的程序，才能完成一些不安全的操作。\n我所需要的权限在用户安装的时候会很明确的告诉用户，下面我就给大家展示一下我应用申请的权限和另外一个著名的壁纸的应用background和一款管理短信的应用申请的权限。\n\n我的软件需要的权限：\n\"\"\n\n看看background（另外一款壁纸的应用）申请的权限：\n\"\"\n\nHandcent SMS申请的权限：\n\n\"\"\n\n短信有短信的权限，联系人有联系人的权限，我都没要申请，请问我如何获取相关的信息。\n\n三、应用主要面向外国用户，但绝对没有获取那些高敏感度的隐私信息！\n\n该应用主要面向外国用户（国内由于网络原因无法正常使用），连接服务器端能够获取到精确适配终端的图片，这是一款非常有用，也深受用户喜爱的应用。它确实拥有数量众多（几百万）的用户，但绝对没有获取那些高敏感度的隐私信息！我每天都收到很多用户的反馈邮件告诉我这个软件多么棒，给他们带来多少乐趣！\n\n四、我本人始终与业界同仁一道，希望建立诚实守信、和谐共生的Android产业生态系统。\n\n随着Android开放性操作平台手机的广泛使用，其应用软件开发市场正呈现蓬勃发展景象。对于提醒用户警惕来自手机上的威胁，我本人向来都是强烈支持的！本人一直始终与业界同仁一道，一直为共建诚实守信、和谐共生的Android产业生态系统而努力，将力量专注于用户需求和技术创新，创造更被用户喜欢的软解，并致力于推动手机应用软件产业持续健康发展。\n\n在此，本人郑重申明，该应用没有获取任何诸如“浏览历史记录，短信，语音邮件密码等”这种高敏感度的信息，并和国外的原作者取得联系，让其修正自己的言论并发布公开道歉，同时对于这种不负责任的言论和评价观点，对我及与我相关的应用进行不负责任的报道造成的影响给予补偿，我将保留追究其法律责任的权利。\n\nps：\n\n如果您有其他的疑问或者问题，欢迎你在我sina微博客（http://t.sina.com.cn/iceskysl）或者sohu微博（http://t.sohu.com/iceskysl）给我沟通！\n

    \n\n
    在看完这条消息后，我立马检查了所有代码，防止这款应用在我不知情的情况下，被他人加入恶意代码，但我一无所获。
    \n现就相关事宜申明如下：
    \n一、我开发的所有程序都没有侵犯到用户的隐私。
    \n\n
    在这个应用中，申请的全部权限为：
    \n<uses-permission android:name="android.permission.INTERNET" />
    \n<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

    \n懂点Android技术的都知道，这些权限都是为了让该软件的功能，能够正常工作所必须的权限（连接网络，获取网络状态，下载壁纸时读写SD卡，设置壁纸，读取手机状态）和Admob的广告精准推送所需要的权限（位置信息，读取手机状态）。
    \n至于获取用户浏览历史记录、短信、语音邮件密码的这些明显侵犯用户隐私的行为，完全是子虚乌有。一方面并没要申请相关的权限；另一方面我还真不知道怎样获取这些敏感信息。另外，admob的精准广告服务中可能是会针对用户的地理位置等信息推送更准确的广告服务。
    \n关于这款应用能获取的设备标识号是用来区分设备的唯一性，免去用户注册的麻烦，而能给用户提供收藏图片的功能；而诸如获取手机屏幕大小是为了能够智能适配合适的图片。在这些设备信息中，请问哪一条会侵犯到用户的隐私。
    \n另外说我可以获取浏览历史信息，这简直就是个天大的笑话。如果懂一点程序的就会知道，要获取浏览器信息必须在程序里申请com.android.browser.permission.READ_HISTORY_BOOKMARKS权限。我的程序完全没有获取到权限，怎么能够获取到历史信息，真是笑话！！！
    \n\n
    二、Android手机的权限管理，在任何没有刷过第三方rom的手机上是很严格的。
    \n Android手机的权限管理，在任何没有刷过第三方rom的手机上是很严格的，在没有相关权限的情况下，要获取那些信息，是完全不可能的。就算是被刷过Rom的手机，也只有具有该ROM制作人的加密签名的程序，才能完成一些不安全的操作。
    \n我所需要的权限在用户安装的时候会很明确的告诉用户，下面我就给大家展示一下我应用申请的权限和另外一个著名的壁纸的应用background和一款管理短信的应用申请的权限。
    \n\n
    我的软件需要的权限：
    \n\n
    看看background（另外一款壁纸的应用）申请的权限：
    \n\n
    Handcent SMS申请的权限：
    \n\n\n
    短信有短信的权限，联系人有联系人的权限，我都没要申请，请问我如何获取相关的信息。
    \n\n
    三、应用主要面向外国用户，但绝对没有获取那些高敏感度的隐私信息！
    \n\n
    该应用主要面向外国用户（国内由于网络原因无法正常使用），连接服务器端能够获取到精确适配终端的图片，这是一款非常有用，也深受用户喜爱的应用。它确实拥有数量众多（几百万）的用户，但绝对没有获取那些高敏感度的隐私信息！我每天都收到很多用户的反馈邮件告诉我这个软件多么棒，给他们带来多少乐趣！
    \n\n
    四、我本人始终与业界同仁一道，希望建立诚实守信、和谐共生的Android产业生态系统。
    \n\n
    随着Android开放性操作平台手机的广泛使用，其应用软件开发市场正呈现蓬勃发展景象。对于提醒用户警惕来自手机上的威胁，我本人向来都是强烈支持的！本人一直始终与业界同仁一道，一直为共建诚实守信、和谐共生的Android产业生态系统而努力，将力量专注于用户需求和技术创新，创造更被用户喜欢的软解，并致力于推动手机应用软件产业持续健康发展。
    \n\n
    在此，本人郑重申明，该应用没有获取任何诸如“浏览历史记录，短信，语音邮件密码等”这种高敏感度的信息，并和国外的原作者取得联系，让其修正自己的言论并发布公开道歉，同时对于这种不负责任的言论和评价观点，对我及与我相关的应用进行不负责任的报道造成的影响给予补偿，我将保留追究其法律责任的权利。

    \nupdate：
    \n写完申明后，去看消息出处看到其竟然做了修改，我早料到其会做相关的行为，所有早些时候截了屏幕如下：
    \n\n\n
    而现在的文章被修改为：
    \n\n\n
    看我用鼠标标识的地方，对关键信息进行了修改，感兴趣的人可以去 http://mobile.venturebeat.com/2010/07/28/android-wallpaper-app-that-steals-your-data-was-downloaded-by-millions/ 查看原文，对于这种标题党用子虚乌有的事情炒作，等消息传播后再修改自己的内容算什么行为！而对国内部分媒体在传播时不但不对真实性进行验证，还添油加醋，歪曲意思的报道，我非常无奈（看到有人还说可以获取信用卡信息，还加密传输，我实在无语）。
    \n\n
    按照我个人的感觉，他们应该紧接着要开始拿这个事件来炒作自己的产品了，我个人懒得去关注，如果有人发现有人借此炒作自己的产品，请帮忙分析分析，看看到底是什么人用这样手法。
    \n\n
    再次update！！！
    \n\n
    通过email和mylookout的人取得联系，说明我取得诸如设备号，手机屏幕大小是为了更智能的给设备适配图片，而获取部分的sim卡号是后来用户反馈说自己换了手机还想使用之前的收藏记录才使用的，这些信息只在该应用中使用，并没提供给任何第三方！
    \n\n
    同时让其确认venturebeat上文章中说到的获取浏览器历史，短信息，密码等高敏感性信息是否是他们说的还是写文章的人自己写的（Lots of my users send me the email ask me why I collect their text message and voicemail passward, I just want to make sure whether you and your ceo said that  I collected browsing history,text message ,voicemail passward during the meeting.）。
    \n\n
    其cto给我回复说他们没有说过我的应用获取过诸如text messages or browsing history这些信息（ We never stated that the wallpaper applications gathered users text messages or browsing history.），是媒体在撰写和传播的时候错误报道了（A member of the press misreported our research and he has since corrected it. ）。

    1. google就前段时间将应用暂停和我一起分析了这个应用，今天发来调查的结果：
    \n\n
    Our investigation has concluded that there's no obvious malicious code in your apps, though the implementation accesses data that it doesn't need to.  We've restored your apps (and they'll be available on Market again once you publish them), and are looking forward to seeing them updated to use ANDROID_ID.  We are likely to make a statement about this issue this week--I'll let you know.

    我早就说过，我配合调查，我把代码提供给他们，google也做出了公正的评判，另外也给我提了一些建议（ANDROID_ID）。
    \n\n
    2. 当时写这篇报道的venturebeat记者Dean Takahashi发来了mail，为自己犯的错误道歉，并道歉该事带来的恶劣影响，会再写一篇文章澄清这个事情以消除影响。

    \r\n以上两中方式，我个人更加喜欢Rails2的多模板支持模式，更加自然和清晰。实用工具：wmlbrowser add-on for Firefox ：可以在FF下直接查看WML网页Opera：支持WML格式显示```\r\n参考资文章：\r\n\r\n1、Making your Rails app mobile with WAP and WML\r\n2、Ruby on Rails (and some WAP)\r\n3、Redesign your site in place using Rails custom mime types\r\n\r\n参考资料：\r\n\r\nW3schools WAP tutorial\r\nW3schools WML reference\r\nWeb based WAP Emulator\r\n\r\n ", "created_at"=>2008-07-01 06:51:55 UTC, "updated_at"=>2012-06-24 15:45:29 UTC, "body_html"=>"
    Rails在WEB开发中独树一帜，取得相当大的成功，但是其内核中尚未支持WML，于是查找了一些资料，如果你使用Rails开发的系统向添加WAP支持，这或许对你有用。
    \n\n
    总的来看，有两个方式来实现对WML的支持，单独支持和整合支持，下面详细的说。
    \n\n
    一、按照一般方式支持
    \n\n
    这个方式和做PC WEB方式是一样的，有个单独的controller或者action，指定特有的layout和页面模板，而这些模板中采用WML语言编写，在请求到来的时候，按照URL中特有的特征字符（比如二级域名）或者Http Head中的标识转向Wap的action，进而显示。详细的步骤基本上是这样的：
    \n\n
    1、在app/controllers/application.rb中增加对WAP格式输出的支持
    \n
    \nRuby代码
    \n
    \n    before_filter :set_wap_content_type, :only => :wap  
    \n      
    \n    def set_wap_content_type  
    \n      @headers["Content-Type"] = “text/vnd.wap.wml; charset=iso-8859-1″  
    \n    end  
    \n
    \n
    \n2、添加一个WAP的全局布局模板app/views/layouts/wap.rhtm
    \n
    \nXML/HTML代码
    \n
    \n    <?xml version=”1.0″?>  
    \n    <!DOCTYPE wml PUBLIC “-//WAPFORUM//DTD WML 1.1//EN” “http://www.wapforum.org/DTD/wml_1.1.xml”>  
    \n    <wml>  
    \n    <card title=”<%= @title %>”>  
    \n    <p align=”center”>  
    \n    <%= @content_for_layout %>  
    \n    </p>  
    \n    </card>  
    \n    </wml>  
    \n
    \n
    \n3、在我的controller中（index）中增加一个action用来响应WAP请求。
    \n
    \nRuby代码
    \n
    \n    def wap  
    \n      @title = "San Francisco Sailing Weather"  
    \n      render(:layout => "wml")  
    \n    end  
    \n
    \n
    \n4、添加相应的view模板app/views/index/wap.rhtml
    \n
    \nXML/HTML代码
    \n
    \n    <%= link_to 'NOAA Marine Forecast', { :controller => '/marine/forecast', :action => 'wap' } %><br/>  
    \n    <%= link_to 'Wind Readings', { :controller => '/marine/wind', :action => 'wap' } %><br/>  
    \n    <%= link_to 'Current Predictions', { :controller => '/marine/tide', :action => 'wap' } %>  
    \n
    \n
    \n 
    \n\n
    二、使用Rails2支持的多模板类型支持
    \n\n
    在Rails2以后，Rails支持多种格式的输出，比如Html，RSS，JS等，当然你还可以定制自己的格式，比如我们这里说的WML，Iphone等，使用起来更简单、自然。
    \n\n
    1、添加MIME格式支持
    \n\n
    在config/environment.rb中增加MIME的格式支持，方式如下：
    \n
    \nRuby代码
    \n
    \n    Mime::Type.register "text/vnd.wap.wml", :wml  
    \n
    \n
    \n
    \n2、判断请求类型
    \n<div class="codeText">
    \n<div class="codeHead">Ruby代码</div>
    \n<ol class="dp-rb" start="1">
    \n    <li class="alt"><span><span class="comment"># application.rb</span><span>  </span></span></li>
    \n    <li><span>before_filter <span class="symbol">:adjust_format_for_beta</span><span>  </span></span></li>
    \n    <li class="alt"><span>  </span></li>
    \n    <li><span>...  </span></li>
    \n    <li class="alt"><span>  </span></li>
    \n    <li><span><span class="keyword">def</span><span> adjust_format_for_beta  </span></span></li>
    \n    <li class="alt"><span>  request.format = <span class="symbol">:beta</span><span> </span><span class="keyword">if</span><span> beta_request?   </span></span></li>
    \n    <li><span><span class="keyword">end</span><span>  </span></span></li>
    \n    <li class="alt"><span>  </span></li>
    \n    <li><span><span class="keyword">def</span><span> beta_request?  </span></span></li>
    \n    <li class="alt"><span>  <span class="keyword">return</span><span> (request.subdomains.first == </span><span class="string">"beta"</span><span> || params[</span><span class="symbol">:format</span><span>] == </span><span class="string">"beta"</span><span>)  </span></span></li>
    \n    <li><span><span class="keyword">end</span><span>  </span></span></li>
    \n</ol>
    \n</div>
    \n<pre style="font-size: 90%;">
    \n<strong>3、添加相应的view代码</strong>比较简单，就是写XML或者WML模板<strong>show.wml.erb</strong>
    \n
    \nXML/HTML代码
    \n
    \n    xml.instruct! :xml, :version => "1.0"  
    \n    xml.wml "xml:lang" => "en-gb" do  
    \n      xml.card :title => "My title here" do  
    \n        xml.p "Something interesting here"  
    \n        xml.p "Something else interesting here."  
    \n      end  
    \n    end  
    \n
    \n
    \n
    \n4、添加输出类型支持
    \n<div class="codeText">
    \n<div class="codeHead">Ruby代码</div>
    \n<ol class="dp-rb" start="1">
    \n    <li class="alt"><span><span class="keyword">def</span><span> index  </span></span></li>
    \n    <li><span>  respond_to <span class="keyword">do</span><span> |format|  </span></span></li>
    \n    <li class="alt"><span>    format.html  </span></li>
    \n    <li><span>    format.wml  </span></li>
    \n    <li class="alt"><span>  <span class="keyword">end</span><span>  </span></span></li>
    \n    <li><span><span class="keyword">end</span><span>  </span></span></li>
    \n</ol>
    \n</div>
    \n<pre style="font-size: 90%;">

    \n如果有人遇到类似问题，请多加留意，呵呵。
    \n\n
    PS：可是，如果通过了多级反向代理的话，X-Forwarded-For的值并不止一个，而是一串Ｉｐ值，究竟哪个才是真正的用户端的真实IP呢？
    \n答案是取X-Forwarded-For中第一个非unknown的有效IP字符串。如：X-Forwarded-For：192.168.1.110, 192.168.1.120, 192.168.1.130, 192.168.1.100,用户真实IP为： 192.168.1.110

    \n找到一个msysgit ，按照里面的说明下载安装就OK了，下面看看如何使用：
    \n-----------------使用---------------
    \n好,下面来个简单教程.标准的 git 教程是行不通的(要加些东西),因为这是windows.主要是没有用户信息.好我的git安装在 c:\\git 以下为命令行.
    \n
    \n1.创建git的数据库
    \nC:\\Git\\bin>git init-db
    \n\n
    2.生成一个文件xxx并加入到git中
    \nC:\\Git\\bin>echo hello > xxx
    \nC:\\Git\\bin>git add xxx
    \n\n
    3.提交[以上两步与标准教程还是一样的,关键是这一步]
    \nC:\\Git\\bin>set home=c:\\
    \nC:\\Git\\bin>git config --global user.name "clq"
    \nC:\\Git\\bin>git commit -m "test"
    \n\n
    一共三个命令,其中第1个是设置用户路径,第2个是设置用户名.而且是每次打开dos命令行后都要有这两个命令,当然你可以写成 bat 文件.第3个才是提交,不能直接写 git commit 因为这个版本好象一定要有注释,那个 "test" 就是我加的注释了.
    \n\n
    4.改一下xxx文件
    \necho world >> xxx
    \n\n
    5.查看一下它和我们原来对比的有什么不同
    \nC:\\Git\\bin>git diff
    \n\n
    结果如下
    \ndiff --git a/xxx b/xxx
    \nindex 907cd4b..360c7f4 100644
    \n--- a/xxx
    \n+++ b/xxx
    \n@@ -1 +1,2 @@
    \nhello
    \n+world
    \n(END)
    \n\n
    用过cvs的都明白了吧.另外这个显示的还得退出,退出命令和vi一样
    \n提交可以用一个命令来完成
    \ngit commit -m "" -a xxx
    \n\n
    省去git add
    \n\n
    C:\\Git\\bin>git show xxx
    \n查看最近一次提交的信息.
    \n\n
    C:\\Git\\bin>git commit -a -m"aa"
    \n\n
    提交全部更改过的文件.

    \r\n
    XML/HTML代码
    \r\n
      \r\n\t
    1. General options:  
      2. \r\n\t
    2.   
      3. \r\n\t
    3. -h or --help  
      4. \r\n\t
    4.     Print quick or full usage details respectively.  
      5. \r\n\t
    5. -r or --recursive  
      6. \r\n\t
    6.     Search directory arguments recursively for files to convert.  
      7. \r\n\t
    7. -d or --delete  
      8. \r\n\t
    8.     delete input files after successful conversion. May not be safe yet!!!  
      9. \r\n\t
    9. -v or --verbose  
      10. \r\n\t
    10.     makes sneetchalizer more chatty.  
      11. \r\n\t
    11. -s or --show-output  
      12. \r\n\t
    12.     shows output from conversion tool.  
      13. \r\n\t
    13. -p or --pretend  
      14. \r\n\t
    14.     don't convert anything. sneetchalizer will go through the motions and print out the commands it would run. Useful for preview- ing a complex command line to ensure it does what you intend. You should interpret this option's output with a grain of salt. For example, if you include the '--sanitize' option, the files will not really be renamed when using --pretend, and as such the command's output will not reflect that the filenames would be changed during an actual run.  
      15. \r\n\t
    15. -t or --terminate  
      16. \r\n\t
    16.     terminate sneetchalizer options. This is useful if you have to convert '--coolDir' or '-groovySong.mp3'. This is the only option whose order on the command line is significant.  
      17. \r\n\t
    17. -D ARG or --out-directory=ARG  
      18. \r\n\t
    18.     write all outfiles to a directory argument. This is useful if you want to (re)encode files directly to a mounted portable device.  
      19. \r\n\t
    19. --strict and --pedantic  
      20. \r\n\t
    20.     many errors that sneetchalizer may encounter are recoverable, such as specifying a directory as argument that contains no files to convert, or conversion failures in general. By default the script will print an error message and move on to the next file. If you use '--strict' then sneetchalizer will bail out at the first sign of trouble except for tag errors. With '--pedantic' the script will stop even on tag errors.   
      21. \r\n\t
    21. --stasis  
      22. \r\n\t
    22.     Preserve timestamp (mtime) of original file.  
      23. \r\n\t
    23. --threads [N]  
      24. \r\n\t
    24.     Experimental. Use threads to create concurrent jobs. This option takes an optional integer argument which represents the number of threads to launch. The default is two. Preliminary tests suggest there is little advantage (and even diminishing returns) when setting this number greater than the number of cores/CPUs you have. Due to the asychronous nature of threads the --verbose and --show-output flags will be silently disabled and most screen output is supressed.   
      25. \r\n\t
    25. --sanitize  
      26. \r\n\t
    26.     Removes ,, ;, :, ', \", %, @, #, and ` from filenames and tags.  
      27. \r\n\t
    27. -n [FORMAT] or --rename[=FORMAT]  
      28. \r\n\t
    28.     rename all outfiles (and temporary wavs) according to FORMAT. FORMAT is a string with special designators to be pulled from the file tags. The following options are available:  
      29. \r\n\t
    29.

      46. \r\n\t
    46.   
      47. \r\n\t
    47. quality and bitrate are passed directly to lame or oggenc depending on mp3 or ogg output format respectively. Both tools can handle either a bitrate or quality argument, so it is important to understand what values are valid for the underlying tool in your specific use case. faac will accept a bitrate argument, but not a quality argument. These options will be silently ignored for any output formats other than mp3, ogg or m4a. Make sure you know what you are doing if you decide to use both in one run, and read each tools manpage for valid values. If these options are omitted the tools builtin defaults are used (-q3 for oggenc and -q5 for lame).  
      48. \r\n\t
    48.

      51. \r\n\t
    51.   
      52. \r\n\t
    52. this option allows you to pass a compression argument to flac and mac. See 'flac --help' and/or 'mac --help' if you don't know what this means.

      60. \r\n\t
    60.   
      61. \r\n\t
    61. Valid output formats are: \"aac\", \"aif\", \"aifc\", \"aiff\", \"aiffc\", \"ape\", \"au\", \"cdr\", \"cdda\", \"copy\", \"flac\", \"m4a\", \"m4b\", \"mpc\", \"mp4\", \"mpp\", \"mp3\", \"mp2\", \"ofr\", \"ofs\", \"ogg\", \"snd\", \"spx\", \"tta\", \"wav\", \"wv\". Valid input formats are all of the above plus \"wma\". You can specify multiple input formats using a comma: 'mp3,m4a,wma'. Input format is only neccesary when passing directory arguments, as file arguments are handled by context (read: file extension). The \"copy\" output option copies files directly, bypassing decoding/encoding steps (useful in conjunction with --rename).

    \r\n另外，你可以运行sneetchalizer -h看到简要的使用说明，也可以使用sneetchalizer --help看到详细的使用信息。\r\n\r\n3、使用示例\r\n\r\n如下简要的写几个使用的示例：\r\n
    \r\n
    使用示例：
    \r\n
      \r\n\t
    1. $ sneetchalizer song.mp3  
      2. \r\n\t
    2.   
      3. \r\n\t
    3. The most simple possible example, creates 'song.wav'.  
      4. \r\n\t
    4.   
      5. \r\n\t
    5. $ sneetchalizer --out=ogg --in=flac -q5 /some/music/dir  
      6. \r\n\t
    6.   
      7. \r\n\t
    7. This example converts every flac file in '/some/music/dir' to ogg format at quality 5.  
      8. \r\n\t
    8.   
      9. \r\n\t
    9. $ sneetchalizer -d --out=mp3 --in=ogg,m4a,wma -b 160 .  
      10. \r\n\t
    10.   
      11. \r\n\t
    11. Converts every ogg, m4a, and wma file in the current directory to a 160 kbps constant bitrate mp3 file. The original files are deleted.  
      12. \r\n\t
    12.   
      13. \r\n\t
    13. $ sneetchalizer --out=mp3 --out-optionhook=\"--preset extreme\" /some/wavs  
      14. \r\n\t
    14.   
      15. \r\n\t
    15. Here we encode every wav in '/some/wavs' to mp3 format passing '--preset extreme' directly to lame.  
      16. \r\n\t
    16.   
      17. \r\n\t
    17. $ sneetchalizer --in=ogg --out=ogg --quality=1 norvegianWood.ogg /some/more/oggs  
      18. \r\n\t
    18.   
      19. \r\n\t
    19. Using the same --in and --out format allows us to resample/encode the file at a different bitrate or quality. Note that this will overwrite the original file so only do this on a copy, or use '-D' to write files to another directory.  
      20. \r\n\t
    20.   
      21. \r\n\t
    21. $ sneetchalizer --in=ogg --out=m4a -D /mnt/ipod/ /some/oggs  
      22. \r\n\t
    22.   
      23. \r\n\t
    23. Here we re-encode some ogg files to m4a format and write them to our mounted iPod.   
      24. \r\n
    \r\n
    \r\n4、注意事项\r\n\r\n本脚本只是粘合剂，其他的tool还是需要另外安装的。\r\n\r\n其他信息请参考其主页说明,如果您有这个方面的问题或经验，欢迎和我讨论。\r\n\r\n\r\n\r\n\r\n ", "created_at"=>2008-10-09 02:49:27 UTC, "updated_at"=>2012-06-24 15:45:30 UTC, "body_html"=>"
    前几天写了“采用Ruby提取MP3的metadata信息”后，就在寻找成熟的Ruby代码做差不多的事情，今天找到一个sneetchalizer，仔细的看了下，非常强大。
    \n\n\n
    sneetchalizer其实只是个粘合剂，因为在*unix下，audio格式转换的lib已经非常丰富和成熟，例如lame,gogo,bladeenc,mplayer等等就非常好用；另外，关于audio的tag信息和metadata信息的提取也有比较成熟的lib了，类似id3lib-ruby library,wmainfo-rb library,ruby-ogginfo library等等。而sneetchalizer只是把这些tools粘合起来。
    \n\n
    其支持的格式有:'aac' 'aif' 'aifc' 'aiff' 'aiffc' 'ape' 'au' 'caf' 'cdda' 'cdr' 'copy' 'fap' 'flac' 'gsm''ircam' 'm4a' 'm4b' 'mat' 'mat4' 'mat5' 'mp2' 'mp3' 'mp4' 'mpc' 'mpp' 'nist' 'ofr''ofs' 'ogg' 'paf' 'pvf' 'raw' 'sd2' 'sds' 'sf' 'snd' 'spx' 'svx' 'tta' 'voc''vox' 'w64' 'wav' 'wma' 'wv' 'xi'
    \n\n
    使用sneetchalizer可以实现audio文件的格式转换和tag信息提取和写入，详细使用方法参考其主页上说明，下面简要的说说起安装方法和使用参数：
    \n\n
    1、安装方法
    \n\n
    直接下载其gz包，sneetchalizer-0.9.0是现在的最新版本。下载解包后可以看到：
    \n
    \nManifest:
    \n
    \n    README                - You're reading it now.  
    \n    LICENSE               - A copy of the GPL, under which sneetchalizer is released.  
    \n    CHANGES               - sneetchalizer's cvs/svn commit log.  
    \n    sneetchalizer         - The script itself.  
    \n    sneetchalizer.1       - The manpage for sneetchalizer.  
    \n    sneetchalizer.desktop - A KDE service menu for converting with Konqueror.  
    \n    install.rb            - A quick and dirty script to install the sneetchalizer.  
    \n
    \n
    \n如果有root权限，可以直接运行install.rb，其会将sneetchalizer拷贝到/usr/bin下，将sneetchalizer.1拷贝到/usr/share/man/man1下。
    \n\n
    2、参数解释
    \n\n
    不翻译了，都挺简单明了的，如下：
    \n
    \nXML/HTML代码
    \n
    \n    General options:

    \n        Print quick or full usage details respectively.  
    \n    -r or --recursive  
    \n        Search directory arguments recursively for files to convert.  
    \n    -d or --delete  
    \n        delete input files after successful conversion. May not be safe yet!!!  
    \n    -v or --verbose  
    \n        makes sneetchalizer more chatty.  
    \n    -s or --show-output  
    \n        shows output from conversion tool.  
    \n    -p or --pretend  
    \n        don't convert anything. sneetchalizer will go through the motions and print out the commands it would run. Useful for preview- ing a complex command line to ensure it does what you intend. You should interpret this option's output with a grain of salt. For example, if you include the '--sanitize' option, the files will not really be renamed when using --pretend, and as such the command's output will not reflect that the filenames would be changed during an actual run.  
    \n    -t or --terminate  
    \n        terminate sneetchalizer options. This is useful if you have to convert '--coolDir' or '-groovySong.mp3'. This is the only option whose order on the command line is significant.  
    \n    -D ARG or --out-directory=ARG  
    \n        write all outfiles to a directory argument. This is useful if you want to (re)encode files directly to a mounted portable device.  
    \n    --strict and --pedantic  
    \n        many errors that sneetchalizer may encounter are recoverable, such as specifying a directory as argument that contains no files to convert, or conversion failures in general. By default the script will print an error message and move on to the next file. If you use '--strict' then sneetchalizer will bail out at the first sign of trouble except for tag errors. With '--pedantic' the script will stop even on tag errors.   
    \n    --stasis  
    \n        Preserve timestamp (mtime) of original file.  
    \n    --threads [N]  
    \n        Experimental. Use threads to create concurrent jobs. This option takes an optional integer argument which represents the number of threads to launch. The default is two. Preliminary tests suggest there is little advantage (and even diminishing returns) when setting this number greater than the number of cores/CPUs you have. Due to the asychronous nature of threads the --verbose and --show-output flags will be silently disabled and most screen output is supressed.   
    \n    --sanitize  
    \n        Removes ,, ;, :, ', ", %, @, #, and ` from filenames and tags.  
    \n    -n [FORMAT] or --rename[=FORMAT]  
    \n        rename all outfiles (and temporary wavs) according to FORMAT. FORMAT is a string with special designators to be pulled from the file tags. The following options are available:  
    \n      
    \n            * %t Song title  
    \n            * %b Album title  
    \n            * %n Track number  
    \n            * %a Artist name  
    \n            * %y Year  
    \n            * %g Genre  
    \n            * %c Comment field  
    \n      
    \n        Directories may be created with this command, as in "%b/%n - %t". The default value of FORMAT is "%n %t".   
    \n      
    \n    Bitrate/Quality/Compression options:  
    \n      
    \n    -b or --bitrate  
    \n        mp3/ogg/m4a bitrate.  
    \n    -q or --quality  
    \n        mp3/ogg quality.  
    \n      
    \n    quality and bitrate are passed directly to lame or oggenc depending on mp3 or ogg output format respectively. Both tools can handle either a bitrate or quality argument, so it is important to understand what values are valid for the underlying tool in your specific use case. faac will accept a bitrate argument, but not a quality argument. These options will be silently ignored for any output formats other than mp3, ogg or m4a. Make sure you know what you are doing if you decide to use both in one run, and read each tools manpage for valid values. If these options are omitted the tools builtin defaults are used (-q3 for oggenc and -q5 for lame).  
    \n      
    \n    -c or --compression  
    \n        flac/mac compression level.  
    \n      
    \n    this option allows you to pass a compression argument to flac and mac. See 'flac --help' and/or 'mac --help' if you don't know what this means.  
    \n      
    \n    Format Options:  
    \n      
    \n    --out=format  
    \n        output format. Default is wav.  
    \n    --in=format[,format..]  
    \n        input format(s). Default is wav.  
    \n      
    \n    Valid output formats are: "aac", "aif", "aifc", "aiff", "aiffc", "ape", "au", "cdr", "cdda", "copy", "flac", "m4a", "m4b", "mpc", "mp4", "mpp", "mp3", "mp2", "ofr", "ofs", "ogg", "snd", "spx", "tta", "wav", "wv". Valid input formats are all of the above plus "wma". You can specify multiple input formats using a comma: 'mp3,m4a,wma'. Input format is only neccesary when passing directory arguments, as file arguments are handled by context (read: file extension). The "copy" output option copies files directly, bypassing decoding/encoding steps (useful in conjunction with --rename).  
    \n      
    \n    Tagging Options:  
    \n      
    \n    --tt or --title  
    \n        Set 'title' tag.  
    \n    --ta or --artist  
    \n        Set 'artist' tag.  
    \n    --tl or --album  
    \n        Set 'album' tag.  
    \n    --ty or --year  
    \n        Set 'year' tag.  
    \n    --tc or --comment  
    \n        Set 'comment' tag.  
    \n    --tg or --genre  
    \n        Set 'genre' tag.  
    \n    --tn or --trackn  
    \n        Set 'track number' tag.  
    \n      
    \n    The short and long versions are different in an important way: Using the long version will clobber any existing tags. The short version will only set the tag if the existing tag has no value. Note that these tags will be placed in _every_ outfile during the run.  
    \n      
    \n    Alternative Encoder/Decoder Options:  
    \n      
    \n    --gogo  
    \n        use gogo to encode mp3 files.  
    \n    --bladeenc  
    \n        use bladeenc to encode mp3 files.  
    \n      
    \n    The default is still 'lame'. If 'lame' is not found, the script will search for one of these two encoders regardless if these options are passed or not.  
    \n      
    \n    Special Options:  
    \n      
    \n    --in-optionhook=ARG  
    \n        add ARG to infile conversion command. Possibly dangerous!  
    \n    --out-optionhook=ARG  
    \n        add ARG to outfile conversion command. Possibly dangerous!

    3、使用示例
    \n\n
    如下简要的写几个使用的示例：
    \n
    \n使用示例：
    \n
    \n    $ sneetchalizer song.mp3  
    \n      
    \n    The most simple possible example, creates 'song.wav'.  
    \n      
    \n    $ sneetchalizer --out=ogg --in=flac -q5 /some/music/dir  
    \n      
    \n    This example converts every flac file in '/some/music/dir' to ogg format at quality 5.  
    \n      
    \n    $ sneetchalizer -d --out=mp3 --in=ogg,m4a,wma -b 160 .  
    \n      
    \n    Converts every ogg, m4a, and wma file in the current directory to a 160 kbps constant bitrate mp3 file. The original files are deleted.  
    \n      
    \n    $ sneetchalizer --out=mp3 --out-optionhook="--preset extreme" /some/wavs  
    \n      
    \n    Here we encode every wav in '/some/wavs' to mp3 format passing '--preset extreme' directly to lame.  
    \n      
    \n    $ sneetchalizer --in=ogg --out=ogg --quality=1 norvegianWood.ogg /some/more/oggs  
    \n      
    \n    Using the same --in and --out format allows us to resample/encode the file at a different bitrate or quality. Note that this will overwrite the original file so only do this on a copy, or use '-D' to write files to another directory.  
    \n      
    \n    $ sneetchalizer --in=ogg --out=m4a -D /mnt/ipod/ /some/oggs  
    \n      
    \n    Here we re-encode some ogg files to m4a format and write them to our mounted iPod.   
    \n
    \n

    Ruby可以很方便的解析XML格式的文档，目前用的比较多的lib主要有三个，分别是：REXML, Hpricot, libxml-ruby，如下选取两个XML文档，分别使用这三个lib解析，感受下各自的速度和易用性。
    \n一、原料
    \n
    \n    posts.xml – Uses xml element for object (post) and xml attributes for object attributes
    \n    timeline.xml – Uses xml element for object (status) and child xml elements for attributes
    \n
    \n二、解析过程
    \n1、REXML
    \n\n
    Pros: In the standard library
    \nCons: Slow, I don’t like the name

    \n
    \n
    \n<code class="ruby"><strong>2、Hpricot</strong><strong>Pros:</strong> Cool name, created by _why, faster than <span class="caps">REXML</span>, also does <span class="caps">HTML</span>, creative <span class="caps">API</span><strong>Cons:</strong> Not as fast as libxml-ruby, more of an <span class="caps">HTML</span> parser linguistically (ie: uses innerHTML instead of text or content, etc.)``

    \n3、libxml-ruby

    \nCons: Hpricot has cooler name, REXML and Hpricot both feel easier to use out of the box

    在Android中使用GoogleMap非常方便，但是有些小技巧或者注意事项你必须牢记，否则调试半天你也不会找到啥线索，浪费时间不说，更让你狂抓，以下技巧都是我在实际项目中遇到的，不断更新和维护，如果你有类似技巧，欢迎分享：
    \n
    （以下技巧是基于SDK 1.0的）
    \n
    一、申请Apikey，并放在正确的位置
    \n
    这个应该都知道，但是是申请得到的key放哪里很多人不知道，可以放在
    \n
    1、XML布局文件中
    \n
    <view android:id="@+id/mv"
    \n   class="com.google.android.maps.MapView"
    \n   android:layout_width="fill_parent"
    \n   android:layout_height="fill_parent"
    \n   android:layout_weight="1" 
    \n   android:apiKey="01Yu9W3X3vbpYT3x33chPXXX7U1Z6jy8WYZXNFA" 
    \n   />
    \n
    2、java中
    \n
            mMapView = new MapView(this, "01Yu9W3X3vbpYT3x33chPxxx7U1Z6jy8WYZXNFA");
    \n
    二、记得导入uses-library 
    \n
     由于1.0版本的修改，使得map包不再是默认的了，使用的时候需要在manifest中的application节点下加入
    \n
    <uses-library android:name="com.google.android.maps" /> 
    \n
    \n
    否则，你将遇到可恶的“java.lang.NoClassDefFoundError: ”，切记！
    \n
    三、需要给予一定的权限
    \n
    因为要使用GoogleMAP的service，所以需要
    \n<uses-permission android:name="android.permission.INTERNET"></uses-permission>
    \n
    如果需要GPS等应用，还需要
    \n
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
    \n
    四、Activity需要继承自MapActivity
    \n
    类似如下代码；
    \n
    package com.iceskysl.showmap;
    \n
    \nimport com.google.android.maps.MapActivity;
    \n
    \nimport android.os.Bundle;
    \n
    \npublic class ShowMap extends MapActivity {
    \n    /** Called when the activity is first created. */
    \n    @Override
    \n    public void onCreate(Bundle savedInstanceState) {
    \n        super.onCreate(savedInstanceState);
    \n        setContentView(R.layout.main);
    \n    }
    \n
    \n    @Override
    \n    protected boolean isRouteDisplayed() {
    \n        // TODO Auto-generated method stub
    \n        return false;
    \n    }
    \n}

    在Android中使用GoogleMap非常方便，但是有些小技巧或者注意事项你必须牢记，否则调试半天你也不会找到啥线索，浪费时间不说，更让你狂抓，以下技巧都是我在实际项目中遇到的，不断更新和维护，如果你有类似技巧，欢迎分享：
    \n（以下技巧是基于SDK 1.0的）
    \n一、申请Apikey，并放在正确的位置
    \n这个应该都知道，但是是申请得到的key放哪里很多人不知道，可以放在
    \n1、XML布局文件中
    \n<view android:id="@+id/mv"
    \n   class="com.google.android.maps.MapView"
    \n   android:layout_width="fill_parent"
    \n   android:layout_height="fill_parent"
    \n   android:layout_weight="1" 
    \n   android:apiKey="01Yu9W3X3vbpYT3x33chPXXX7U1Z6jy8WYZXNFA" 
    \n   />
    \n2、java中
    \n        mMapView = new MapView(this, "01Yu9W3X3vbpYT3x33chPxxx7U1Z6jy8WYZXNFA");
    \n二、记得导入uses-library

    • \n
  • Use HTTP Cache Control to tell the browser what it can cache.  --this is true,etag is great.
    • \n
  • Use Sphinx for text search.  --sometimes,you do have others chose.
    • \n
  • Use InnoDB for more crash resistant and faster writes.  --maybe it's right.
    • \n
  • Don't use textbook Rails ActiveRecord objects. Use New Relic to find exactly what is slow in your system. --yep
    • \n
  • Use memcache later so you find your database bottlenecks now. --this is very important.
    • \n
  • Use mongrel proctitle to find your slow queries. You are only as fast as your slowest queries. -maybe mongrel is not only chose,think about thin,ok?
    • \n
  • Use asynchronous job queuing to do work in parallel.  --yes,but sometimes crontab is enough.
    • \n
  • Use monitoring so you'll know when your site went down and why. --that's it,just do it.
    • \n
  • Learn by reading the source code, fixing problems, and submitting them back to the community.  --very userfull when you got some strange questions..
    • \n
  • Use new plugins. Old plugins can't be trusted. --and check chang histroy carefully.

    • All paths must be either absolute or relative to the path from which god was started.
      • \n

    To load a config into a running god, issue the following command:
    \n
    $ sudo god load path/to/config.god
    # god load /data/www/api/config/config_thin_api.god```\n
    Config files that are loaded dynamically can contain anything that a normal config file contains, however, global options such as God.pid_file_directory``` blocks will be ignored (and produce a warning in the logs).

    \n1.DYNAMICALLY LOADING CONFIG FILES INTO AN ALREADY RUNNING GOD
    \n
    \nGod allows you to load or reload configurations into an already running instance. There are a few things to consider when doing this:
    \n
    \n    Existng Watches with the same name<span class="Apple-converted-space">&nbsp;</span>as the incoming Watches will be overidden by the new config.</li>
    \n    <li style="margin: 0px; font-size: 13px;">All paths must be either absolute or relative to the path from which god was started.</li>
    \n</ul>
    \n<p style="margin: 0px 0px 1em; font-size: 13px;">To load a config into a running god, issue the following command:</p>
    \n<pre style="border: 1px solid rgb(204, 204, 204); margin: 1em 0px; padding: 1em; font-size: 10px; line-height: 1.3; background-color: rgb(239, 239, 239);">$ sudo god load path/to/config.god<br /># god load /data/www/api/config/config_thin_api.god
    \nConfig files that are loaded dynamically can contain anything that a normal config file contains, however, global options such as God.pid_file_directory``` blocks will be ignored (and produce a warning in the logs).

    System error: 17 = File exists
    \n
    \n
    这咋回事，再查资料，原来.MRG是创建MERGE表的时候创建的，已经存在了。
    \n
    \n
    那就先把这个MERGE表干掉，再创建：
    \n
    先看下这个表是咋定义的：
    \n
    mysql>  show create table rails_logs;
    \n
    \n
    记录下SQL，接着drop掉。
    \n
    mysql> DROP  table rails_logs;
    \n
    Query OK, 0 rows affected (0.36 sec)
    \n
    \n
    再truncate我的目标表
    \n
    mysql> truncate table  rails_logs_081023;
    \n
    Query OK, 0 rows affected (4.22 sec)
    \n
    \n
    \n
    够快的，11042292条数据4S搞定，接着再创建下这个MERGE表，执行下上面记录的SQL就好了。
    \n
    \n
    最后确认下这表没啥问题：
    \n
    \n
    mysql> select count(id) from rails_logs;
    \n
    +-----------+
    \n
    | count(id) |
    \n
    +-----------+
    \n
    |         0 |
    \n
    +-----------+
    \n
    1 row in set (0.00 sec)
    \n
    \n
    OK，搞定，空间有了，天下太平了。

    \n
    \n
    问题：有一个拥有1亿条数据的表，只需要保留其中的5条，其他删除，如何做？
    \n
    这就需要用truncate table来搞定了，如下：
    \n
    select 5条数据 into #临时表 from 1亿条数据的牛X表
    \n
    truncate table 1亿条数据的牛X表
    \n
    --让它牛X，不到10毫秒干掉它。
    \n
    insert 1亿条数据的牛X表 select * from #临时表
    \n
    drop table #临时表
    \n

    在项目里用了memcached和cache_fu，其默认的 get_cache(id)还是非常方便的，但是对于另外一个用的比较多的find_by_xx这样的，貌似没看到有现成的方法可以使用。
    \n看到其提供了caches方法，其可以接收参数with参数，那么就可以直接利用了，方法如下
    \n@client =Client.caches(:find_by_api_key,:with => api_key)

As a result, it is possible for the extra I/O to make the modified approach slower, not faster. To avoid a slowdown, the optimization is used only if the total size of the extra columns in the sort tuple does not exceed the value of the max_length_for_sort_data system variable. (A symptom of setting the value of this variable too high is that you should see high disk activity and low CPU activity.)

    \n+---------------------------+------------+
    \n| Variable_name             | Value      |
    \n+---------------------------+------------+
    \n| max_length_for_sort_data  | 1024       |
    \n| max_sort_length           | 1024       |
    \n| myisam_max_sort_file_size | 2146435072 |
    \n| myisam_sort_buffer_size   | 67108864   |
    \n| sort_buffer_size          | 8388608    |
    \n+---------------------------+------------+
    \n5 rows in set (0.00 sec)
    \n\n
    不晓得是做啥用的，查了下资料：
    \nhttp://forge.mysql.com/wiki/MySQL_Internals_Algorithms
    \n\n
    Using the modified filesort algorithm, the tuples are longer than the pairs used in the original method, and fewer of them fit in the sort buffer (the size of which is given by sort_buffer_size). As a result, it is possible for the extra I/O to make the modified approach slower, not faster. To avoid a slowdown, the optimization is used only if the total size of the extra columns in the sort tuple does not exceed the value of the max_length_for_sort_data system variable. (A symptom of setting the value of this variable too high is that you should see high disk activity and low CPU activity.)
    \n\n
    mysql的filesort有两个方法,MySQL 4.1之前是使用方法A, 之后版本会使用改进的算法B, 但使用方法B的前提是列长度的值小于max_length_for_sort_data, 但我们系统中的列的长度的值会大于1024. 因此也就是说在sort的时候, 是在使用方法A, 而方法A的性能比较差

    配置
    \n\n
    那么应该怎样来配置成我喜欢的颜色呢？下面我们就来详细说一些这些配置。
    \n\n
    ~/.bash_profile是bash shell中当前登录用户的配置文件。bash是“终端”中默认的shell。
    \n\n
    alias ls=”ls -G”是给”ls -G”起了一个别名，当执行ls时，就相当于执行了ls -G。
    \n\n
    CLICOLOR是用来设置是否进行颜色的显示。CLI是Command Line Interface的缩写。
    \nLSCOLORS是用来设置当CLICOLOR被启用后，各种文件类型的颜色。LSCOLORS的值中每两个字母为一组，分别设置某个文件类型的文字颜色和背景颜色。LSCOLORS中一共11组颜色设置，按照先后顺序，分别对以下的文件类型进行设置：
    \n\n
    directory
    \nsymbolic link
    \nsocket
    \npipe
    \nexecutable
    \nblock special
    \ncharacter special
    \nexecutable with setuid bit set
    \nexecutable with setgid bit set
    \ndirectory writable to others, with sticky bit
    \ndirectory writable to others, without sticky bit
    \nLSCOLORS中，字母代表的颜色如下：
    \n\n
    a 黑色
    \nb 红色
    \nc 绿色
    \nd 棕色
    \ne 蓝色
    \nf 洋红色
    \ng 青色
    \nh 浅灰色
    \nA 黑色粗体
    \nB 红色粗体
    \nC 绿色粗体
    \nD 棕色粗体
    \nE 蓝色粗体
    \nF 洋红色粗体
    \nG 青色粗体
    \nH 浅灰色粗体
    \nx 系统默认颜色
    \n所以，如果我们想把目录显示成红色，就可以把LSCOLORS设置为bxfxaxdxcxegedabagacad就可以了

    现就相关事宜申明如下：
    \n一、我开发的所有程序都没有侵犯到用户的隐私。\n\n在这个应用中，申请的全部权限为：\n
    <uses-permission android:name=\"android.permission.INTERNET\" />
    \n
    <uses-permission android:name=\"android.permission.ACCESS_NETWORK_STATE\" />
    \n
    <uses-permission android:name=\"android.permission.WRITE_EXTERNAL_STORAGE\" />
    \n
    <uses-permission android:name=\"android.permission.SET_WALLPAPER\" />
    \n
    <uses-permission android:name=\"android.permission.READ_PHONE_STATE\" />
    \n
    <uses-permission android:name=\"android.permission.ACCESS_COARSE_LOCATION\" />
    \n懂点Android技术的都知道，这些权限都是为了让该软件的功能，能够正常工作所必须的权限（连接网络，获取网络状态，下载壁纸时读写SD卡，设置壁纸，读取手机状态）和Admob的广告精准推送所需要的权限（位置信息，读取手机状态）。\n至于获取用户浏览历史记录、短信、语音邮件密码的这些明显侵犯用户隐私的行为，完全是子虚乌有。一方面并没要申请相关的权限；另一方面我还真不知道怎样获取这些敏感信息。另外，admob的精准广告服务中可能是会针对用户的地理位置等信息推送更准确的广告服务。\n关于这款应用能获取的设备标识号是用来区分设备的唯一性，免去用户注册的麻烦，而能给用户提供收藏图片的功能；而诸如获取手机屏幕大小是为了能够智能适配合适的图片。在这些设备信息中，请问哪一条会侵犯到用户的隐私。\n另外说我可以获取浏览历史信息，这简直就是个天大的笑话。如果懂一点程序的就会知道，要获取浏览器信息必须在程序里申请com.android.browser.permission.READ_HISTORY_BOOKMARKS权限。我的程序完全没有获取到权限，怎么能够获取到历史信息，真是笑话！！！\n\n二、Android手机的权限管理，在任何没有刷过第三方rom的手机上是很严格的。\n Android手机的权限管理，在任何没有刷过第三方rom的手机上是很严格的，在没有相关权限的情况下，要获取那些信息，是完全不可能的。就算是被刷过Rom的手机，也只有具有该ROM制作人的加密签名的程序，才能完成一些不安全的操作。\n我所需要的权限在用户安装的时候会很明确的告诉用户，下面我就给大家展示一下我应用申请的权限和另外一个著名的壁纸的应用background和一款管理短信的应用申请的权限。\n\n我的软件需要的权限：\n\"\"\n\n看看background（另外一款壁纸的应用）申请的权限：\n\"\"\n\nHandcent SMS申请的权限：\n\n\"\"\n\n短信有短信的权限，联系人有联系人的权限，我都没要申请，请问我如何获取相关的信息。\n\n三、应用主要面向外国用户，但绝对没有获取那些高敏感度的隐私信息！\n\n该应用主要面向外国用户（国内由于网络原因无法正常使用），连接服务器端能够获取到精确适配终端的图片，这是一款非常有用，也深受用户喜爱的应用。它确实拥有数量众多（几百万）的用户，但绝对没有获取那些高敏感度的隐私信息！我每天都收到很多用户的反馈邮件告诉我这个软件多么棒，给他们带来多少乐趣！\n\n四、我本人始终与业界同仁一道，希望建立诚实守信、和谐共生的Android产业生态系统。\n\n随着Android开放性操作平台手机的广泛使用，其应用软件开发市场正呈现蓬勃发展景象。对于提醒用户警惕来自手机上的威胁，我本人向来都是强烈支持的！本人一直始终与业界同仁一道，一直为共建诚实守信、和谐共生的Android产业生态系统而努力，将力量专注于用户需求和技术创新，创造更被用户喜欢的软解，并致力于推动手机应用软件产业持续健康发展。\n\n在此，本人郑重申明，该应用没有获取任何诸如“浏览历史记录，短信，语音邮件密码等”这种高敏感度的信息，并和国外的原作者取得联系，让其修正自己的言论并发布公开道歉，同时对于这种不负责任的言论和评价观点，对我及与我相关的应用进行不负责任的报道造成的影响给予补偿，我将保留追究其法律责任的权利。\n\nps：\n\n如果您有其他的疑问或者问题，欢迎你在我sina微博客（http://t.sina.com.cn/iceskysl）或者sohu微博（http://t.sohu.com/iceskysl）给我沟通！\n
    update：

    \n\n
    “拉斯维加斯黑帽大会上，Lookout 的安全人员指出，一个伪装成Android手机壁纸应用的偷窃个人信息程序已经被下载了百万次，它会收集您的个人资料，并将其发送到一个来自中国深圳的神秘网站imnet.us中。安全人员(Kevin MaHaffey)估计这款程序是由正常的壁纸应用修改而来，黑客将其上传到Android Market，希望装饰自己手机的用户因此而中招。泄漏的数据包括浏览历史记录，短信，手机的SIM卡号码，用户识别号，语音邮件，甚至是密码，他警告称每个人都应该警惕来自手机上的威胁。”
    \n\n
    在看完这条消息后，我立马检查了所有代码，防止这款应用在我不知情的情况下，被他人加入恶意代码，但我一无所获。
    \n现就相关事宜申明如下：
    \n一、我开发的所有程序都没有侵犯到用户的隐私。
    \n\n
    在这个应用中，申请的全部权限为：
    \n<uses-permission android:name="android.permission.INTERNET" />
    \n<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    \n<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    \n<uses-permission android:name="android.permission.SET_WALLPAPER" />
    \n<uses-permission android:name="android.permission.READ_PHONE_STATE" />
    \n<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    \n懂点Android技术的都知道，这些权限都是为了让该软件的功能，能够正常工作所必须的权限（连接网络，获取网络状态，下载壁纸时读写SD卡，设置壁纸，读取手机状态）和Admob的广告精准推送所需要的权限（位置信息，读取手机状态）。
    \n至于获取用户浏览历史记录、短信、语音邮件密码的这些明显侵犯用户隐私的行为，完全是子虚乌有。一方面并没要申请相关的权限；另一方面我还真不知道怎样获取这些敏感信息。另外，admob的精准广告服务中可能是会针对用户的地理位置等信息推送更准确的广告服务。
    \n关于这款应用能获取的设备标识号是用来区分设备的唯一性，免去用户注册的麻烦，而能给用户提供收藏图片的功能；而诸如获取手机屏幕大小是为了能够智能适配合适的图片。在这些设备信息中，请问哪一条会侵犯到用户的隐私。
    \n另外说我可以获取浏览历史信息，这简直就是个天大的笑话。如果懂一点程序的就会知道，要获取浏览器信息必须在程序里申请com.android.browser.permission.READ_HISTORY_BOOKMARKS权限。我的程序完全没有获取到权限，怎么能够获取到历史信息，真是笑话！！！
    \n\n
    二、Android手机的权限管理，在任何没有刷过第三方rom的手机上是很严格的。
    \n Android手机的权限管理，在任何没有刷过第三方rom的手机上是很严格的，在没有相关权限的情况下，要获取那些信息，是完全不可能的。就算是被刷过Rom的手机，也只有具有该ROM制作人的加密签名的程序，才能完成一些不安全的操作。
    \n我所需要的权限在用户安装的时候会很明确的告诉用户，下面我就给大家展示一下我应用申请的权限和另外一个著名的壁纸的应用background和一款管理短信的应用申请的权限。
    \n\n
    我的软件需要的权限：
    \n\n
    看看background（另外一款壁纸的应用）申请的权限：
    \n\n
    Handcent SMS申请的权限：
    \n\n\n
    短信有短信的权限，联系人有联系人的权限，我都没要申请，请问我如何获取相关的信息。
    \n\n
    三、应用主要面向外国用户，但绝对没有获取那些高敏感度的隐私信息！
    \n\n
    该应用主要面向外国用户（国内由于网络原因无法正常使用），连接服务器端能够获取到精确适配终端的图片，这是一款非常有用，也深受用户喜爱的应用。它确实拥有数量众多（几百万）的用户，但绝对没有获取那些高敏感度的隐私信息！我每天都收到很多用户的反馈邮件告诉我这个软件多么棒，给他们带来多少乐趣！
    \n\n
    四、我本人始终与业界同仁一道，希望建立诚实守信、和谐共生的Android产业生态系统。
    \n\n
    随着Android开放性操作平台手机的广泛使用，其应用软件开发市场正呈现蓬勃发展景象。对于提醒用户警惕来自手机上的威胁，我本人向来都是强烈支持的！本人一直始终与业界同仁一道，一直为共建诚实守信、和谐共生的Android产业生态系统而努力，将力量专注于用户需求和技术创新，创造更被用户喜欢的软解，并致力于推动手机应用软件产业持续健康发展。
    \n\n
    在此，本人郑重申明，该应用没有获取任何诸如“浏览历史记录，短信，语音邮件密码等”这种高敏感度的信息，并和国外的原作者取得联系，让其修正自己的言论并发布公开道歉，同时对于这种不负责任的言论和评价观点，对我及与我相关的应用进行不负责任的报道造成的影响给予补偿，我将保留追究其法律责任的权利。
    \n\n
    ps：
    \n\n
    如果您有其他的疑问或者问题，欢迎你在我sina微博客（http://t.sina.com.cn/iceskysl）或者sohu微博（http://t.sohu.com/iceskysl）给我沟通！
    \nupdate：
    \n写完申明后，去看消息出处看到其竟然做了修改，我早料到其会做相关的行为，所有早些时候截了屏幕如下：
    \n\n\n
    而现在的文章被修改为：
    \n\n\n
    看我用鼠标标识的地方，对关键信息进行了修改，感兴趣的人可以去 http://mobile.venturebeat.com/2010/07/28/android-wallpaper-app-that-steals-your-data-was-downloaded-by-millions/ 查看原文，对于这种标题党用子虚乌有的事情炒作，等消息传播后再修改自己的内容算什么行为！而对国内部分媒体在传播时不但不对真实性进行验证，还添油加醋，歪曲意思的报道，我非常无奈（看到有人还说可以获取信用卡信息，还加密传输，我实在无语）。
    \n\n
    按照我个人的感觉，他们应该紧接着要开始拿这个事件来炒作自己的产品了，我个人懒得去关注，如果有人发现有人借此炒作自己的产品，请帮忙分析分析，看看到底是什么人用这样手法。
    \n\n
    再次update！！！
    \n\n
    通过email和mylookout的人取得联系，说明我取得诸如设备号，手机屏幕大小是为了更智能的给设备适配图片，而获取部分的sim卡号是后来用户反馈说自己换了手机还想使用之前的收藏记录才使用的，这些信息只在该应用中使用，并没提供给任何第三方！
    \n\n
    同时让其确认venturebeat上文章中说到的获取浏览器历史，短信息，密码等高敏感性信息是否是他们说的还是写文章的人自己写的（Lots of my users send me the email ask me why I collect their text message and voicemail passward, I just want to make sure whether you and your ceo said that  I collected browsing history,text message ,voicemail passward during the meeting.）。
    \n\n
    其cto给我回复说他们没有说过我的应用获取过诸如text messages or browsing history这些信息（ We never stated that the wallpaper applications gathered users text messages or browsing history.），是媒体在撰写和传播的时候错误报道了（A member of the press misreported our research and he has since corrected it. ）。
    \n\n
    我非常无语～
    \n\n
    2010年8月4日第二次次update！
    \n\n
    多谢这些天很多朋友的关心，我很好，谢谢！这些天和google android组，lookout公司和venturebeat的作者，以及国内外很多媒体，博客们，记者们都有很多的接触。
    \n\n
    1. google就前段时间将应用暂停和我一起分析了这个应用，今天发来调查的结果：
    \n\n
    Our investigation has concluded that there's no obvious malicious code in your apps, though the implementation accesses data that it doesn't need to.  We've restored your apps (and they'll be available on Market again once you publish them), and are looking forward to seeing them updated to use ANDROID_ID.  We are likely to make a statement about this issue this week--I'll let you know.
    \n\n
    我早就说过，我配合调查，我把代码提供给他们，google也做出了公正的评判，另外也给我提了一些建议（ANDROID_ID）。
    \n\n
    2. 当时写这篇报道的venturebeat记者Dean Takahashi发来了mail，为自己犯的错误道歉，并道歉该事带来的恶劣影响，会再写一篇文章澄清这个事情以消除影响。
    \n\n
    3. 那个安全公司lookout的人写邮件来要于我一起“ We wanted to coordinate with you to prevent further misunderstandings. ”。
    \n\n
    4.好几个不认识的国外记者很负责任，发邮件和gt和我交流询问事情的真相，并帮我喊冤，谢谢这些有职业精神的记者们。
    \n\n
    这个事情到这差不多就结束了，其中看到很多假丑恶，也看到很多真善美！谢谢所有帮助过我的人（很多很多，就不一一列举）。

    其实我的需求蛮简单的，大概如下：
    \n1. 需要支持快捷键（最好是手不离开键盘能完成全部操作，或者是纪录，整理list的主要工作）
    \n2. 需要支持子任务（最好是不限制级的，目前能用到3级别）
    \n3. 界面简洁，再简洁
    \n4. 支持多端访问，至少在电脑和手机（android&iphone)可以使用
    \n5. 可以打印或者email给朋友
    \n\n
    最终还是回到了Google Task，经过一段时间的使用，我现在已经非常喜欢Google Task，也给我的效率带来很大帮助，我可以把我的方式分享下。
    \n1. 每天开电脑的第一件事情就是开gmail，处理完邮件开始工作，顺手把gmail里把Google Task打开，并pop up出一个单独的窗口，拖拉到合适的大小；（我工作的时候是两个显示器，就把这个窗口一直放在外接显示器的边上，抬眼可见）
    \n2. 每周一个list，名字是时间范围，比如2012.02.06－2012.02.12；
    \n3. 周一的时候会尽量把本周要做的事情列进去（按照事情的类型或者项目，比如公司事务，eoemarket相关），再把要做的事情一个一个输入进去，Google Task的输入很方便，用好tab键和shift tab键来调整层级；用好Ctrl + Up和Ctrl + Down来调整顺序，用Shift + Enter进入到具体的事情中撰写详细，写完再Shift + Enter回到列表；
    \n4. 每次做事情的时候，可以用Tab再细分，一个一个执行掉；完成后回到Google Task，用Option + Enter 标识这个完成（Option + Enter这个快捷键在官方帮助文档和tips里都没，我自己找出来的，mac电脑）；另外勾选上级条目可以把下级条目都标记完成～
    \n5. 每次遇到新的事情直接添加进去，经常review，如此反复就好了～
    \n6. 有的时候还通过打印和发送邮件通知其他人我都做了什么；
    \n\n
    此外，Google Task提供如下方式的使用，我个人觉得足够了
    \n1. gmail中集成/igoogle集成
    \n2. iphone客户端，android客户端（第三方开发的）
    \n3. chrome插件
    \n4. 桌面客户端（没找到，也不怎么用）
    \n5. api接口（或者自己写）
    \n\n
    如果硬说还可以有些期待的话，我的是这样的：
    \n1. 谁写个更好用的iphone客户端（现在app store上的质量一般，而且收费，哪天我心血来潮我来写一个去～）
    \n2. 可以把一个list里没完成的复制到另外一个list中
    \n3. 真木了
    \n\n
    我的个人建议是：必须用好快捷键！
    \n\n
    希望我的这篇介绍能让你喜欢Google Task，并对自己有所帮助

    大家知道，全文检索（特别是中文全文检索）中有两个比较重要的指标，性能和中文分词技术，由于性能要求，使得其必须采用C/C++的检索引擎才有生存的空间，其二是中文分词等，这也是个难题。
    \n在Java中lucene是绝对的权威和首选，虽然其对中文分词支持也不是很好，但是有很多第三方的程序可以集成起来实现相关功能，而在Rails中，至今尚无权威的解决方案，最开始的时候是Ferret一枝独秀，现在另外一个很优秀的Sphinx。

    \n
    \n    # vulnerable controller code  
    \n    User.find(:all, :limit => params[:limit])  
    \n      
    \n    User.find(:all, :limit => 10, :offset => params[:offset])  
    \n      
    \n    # with params[:offset] or params[:limit] set to '; DROP TABLE users;'  
    \n    # you got a big problem ...  
    \n
    \n
    \n如上，我们直接从Http的params中取得limit或者offset参数，直接放在SQL的find中，如果在offset中构造邪恶代码的话，肯定会造成大问题。
    \n\n
    幸好，Mysql默认的是不许一次API调用执行多条SQL，但是这个问题还是存在的，但是PostgreSQL和 SQLite就没那么幸运了，按照上面说的，你可以自己测试下。
    \n\n
    现在的Rails2.1版本中已经修复了PostgreSQL 和SQLite中存在的问题，但是并没有其在Mysql中存在的问题（虽然现在尚且无法利用），后面的Rails2.1.1版本中已经修复了。

    \n\n
    一、按照一般方式支持
    \n\n

    \n    </wml>  
    \n
    \n
    \n3、在我的controller中（index）中增加一个action用来响应WAP请求。
    \n
    \nRuby代码
    \n
    \n    def wap  
    \n      @title = "San Francisco Sailing Weather"

    \n    end  
    \n
    \n
    \n4、添加相应的view模板app/views/index/wap.rhtml
    \n
    \nXML/HTML代码
    \n
    \n    <%= link_to 'NOAA Marine Forecast', { :controller => '/marine/forecast', :action => 'wap' } %><br/>  
    \n    <%= link_to 'Wind Readings', { :controller => '/marine/wind', :action => 'wap' } %><br/>

    在Rails2以后，Rails支持多种格式的输出，比如Html，RSS，JS等，当然你还可以定制自己的格式，比如我们这里说的WML，Iphone等，使用起来更简单、自然。
    \n\n
    1、添加MIME格式支持
    \n\n
    在config/environment.rb中增加MIME的格式支持，方式如下：
    \n
    \nRuby代码
    \n
    \n    Mime::Type.register "text/vnd.wap.wml", :wml  
    \n
    \n
    \n
    \n2、判断请求类型

    \n</ol>
    \n</div>
    \n<pre style="font-size: 90%;">
    \n<strong>3、添加相应的view代码</strong>比较简单，就是写XML或者WML模板<strong>show.wml.erb</strong>
    \n
    \nXML/HTML代码
    \n
    \n    xml.instruct! :xml, :version => "1.0"  
    \n    xml.wml "xml:lang" => "en-gb" do  
    \n      xml.card :title => "My title here" do  
    \n        xml.p "Something interesting here"  
    \n        xml.p "Something else interesting here."  
    \n      end  
    \n    end  
    \n
    \n
    \n
    \n4、添加输出类型支持
    \n<div class="codeText">
    \n<div class="codeHead">Ruby代码</div>
    \n<ol class="dp-rb" start="1">

    1. General options:  
      2. \r\n\t
    2.   
      3. \r\n\t
    3. -h or --help  
      4. \r\n\t
    4.     Print quick or full usage details respectively.  
      5. \r\n\t
    5. -r or --recursive  
      6. \r\n\t
    6.     Search directory arguments recursively for files to convert.  
      7. \r\n\t
    7. -d or --delete  
      8. \r\n\t
    8.     delete input files after successful conversion. May not be safe yet!!!  
      9. \r\n\t
    9. -v or --verbose  
      10. \r\n\t
    10.     makes sneetchalizer more chatty.  
      11. \r\n\t
    11. -s or --show-output  
      12. \r\n\t
    12.     shows output from conversion tool.  
      13. \r\n\t
    13. -p or --pretend  
      14. \r\n\t
    14.     don't convert anything. sneetchalizer will go through the motions and print out the commands it would run. Useful for preview- ing a complex command line to ensure it does what you intend. You should interpret this option's output with a grain of salt. For example, if you include the '--sanitize' option, the files will not really be renamed when using --pretend, and as such the command's output will not reflect that the filenames would be changed during an actual run.  
      15. \r\n\t
    15. -t or --terminate  
      16. \r\n\t
    16.     terminate sneetchalizer options. This is useful if you have to convert '--coolDir' or '-groovySong.mp3'. This is the only option whose order on the command line is significant.  
      17. \r\n\t
    17. -D ARG or --out-directory=ARG  
      18. \r\n\t
    18.     write all outfiles to a directory argument. This is useful if you want to (re)encode files directly to a mounted portable device.  
      19. \r\n\t
    19. --strict and --pedantic  
      20. \r\n\t
    20.     many errors that sneetchalizer may encounter are recoverable, such as specifying a directory as argument that contains no files to convert, or conversion failures in general. By default the script will print an error message and move on to the next file. If you use '--strict' then sneetchalizer will bail out at the first sign of trouble except for tag errors. With '--pedantic' the script will stop even on tag errors.   
      21. \r\n\t
    21. --stasis  
      22. \r\n\t
    22.     Preserve timestamp (mtime) of original file.  
      23. \r\n\t
    23. --threads [N]  
      24. \r\n\t
    24.     Experimental. Use threads to create concurrent jobs. This option takes an optional integer argument which represents the number of threads to launch. The default is two. Preliminary tests suggest there is little advantage (and even diminishing returns) when setting this number greater than the number of cores/CPUs you have. Due to the asychronous nature of threads the --verbose and --show-output flags will be silently disabled and most screen output is supressed.   
      25. \r\n\t
    25. --sanitize  
      26. \r\n\t
    26.     Removes ,, ;, :, ', \", %, @, #, and ` from filenames and tags.  
      27. \r\n\t
    27. -n [FORMAT] or --rename[=FORMAT]  
      28. \r\n\t
    28.     rename all outfiles (and temporary wavs) according to FORMAT. FORMAT is a string with special designators to be pulled from the file tags. The following options are available:

      47. \r\n\t
    47. quality and bitrate are passed directly to lame or oggenc depending on mp3 or ogg output format respectively. Both tools can handle either a bitrate or quality argument, so it is important to understand what values are valid for the underlying tool in your specific use case. faac will accept a bitrate argument, but not a quality argument. These options will be silently ignored for any output formats other than mp3, ogg or m4a. Make sure you know what you are doing if you decide to use both in one run, and read each tools manpage for valid values. If these options are omitted the tools builtin defaults are used (-q3 for oggenc and -q5 for lame).

    \r\n
    使用示例：
    \r\n
      \r\n\t
    1. $ sneetchalizer song.mp3  
      2. \r\n\t
    2.   
      3. \r\n\t
    3. The most simple possible example, creates 'song.wav'.  
      4. \r\n\t
    4.   
      5. \r\n\t
    5. $ sneetchalizer --out=ogg --in=flac -q5 /some/music/dir  
      6. \r\n\t
    6.   
      7. \r\n\t
    7. This example converts every flac file in '/some/music/dir' to ogg format at quality 5.  
      8. \r\n\t

      10. \r\n\t
    10.   
      11. \r\n\t
    11. Converts every ogg, m4a, and wma file in the current directory to a 160 kbps constant bitrate mp3 file. The original files are deleted.  
      12. \r\n\t

      13. \r\n\t
    13. $ sneetchalizer --out=mp3 --out-optionhook=\"--preset extreme\" /some/wavs  
      14. \r\n\t
    14.   
      15. \r\n\t
    15. Here we encode every wav in '/some/wavs' to mp3 format passing '--preset extreme' directly to lame.  
      16. \r\n\t
    16.

      19. \r\n\t
    19. Using the same --in and --out format allows us to resample/encode the file at a different bitrate or quality. Note that this will overwrite the original file so only do this on a copy, or use '-D' to write files to another directory.

    \r\n4、注意事项\r\n\r\n本脚本只是粘合剂，其他的tool还是需要另外安装的。\r\n\r\n其他信息请参考其主页说明,如果您有这个方面的问题或经验，欢迎和我讨论。\r\n\r\n\r\n\r\n\r\n ", "created_at"=>2008-10-09 02:49:27 UTC, "updated_at"=>2012-06-24 15:45:36 UTC, "body_html"=>"
    前几天写了“采用Ruby提取MP3的metadata信息”后，就在寻找成熟的Ruby代码做差不多的事情，今天找到一个sneetchalizer，仔细的看了下，非常强大。
    \n\n\n
    sneetchalizer其实只是个粘合剂，因为在*unix下，audio格式转换的lib已经非常丰富和成熟，例如lame,gogo,bladeenc,mplayer等等就非常好用；另外，关于audio的tag信息和metadata信息的提取也有比较成熟的lib了，类似id3lib-ruby library,wmainfo-rb library,ruby-ogginfo library等等。而sneetchalizer只是把这些tools粘合起来。
    \n\n
    其支持的格式有:'aac' 'aif' 'aifc' 'aiff' 'aiffc' 'ape' 'au' 'caf' 'cdda' 'cdr' 'copy' 'fap' 'flac' 'gsm''ircam' 'm4a' 'm4b' 'mat' 'mat4' 'mat5' 'mp2' 'mp3' 'mp4' 'mpc' 'mpp' 'nist' 'ofr''ofs' 'ogg' 'paf' 'pvf' 'raw' 'sd2' 'sds' 'sf' 'snd' 'spx' 'svx' 'tta' 'voc''vox' 'w64' 'wav' 'wma' 'wv' 'xi'
    \n\n
    使用sneetchalizer可以实现audio文件的格式转换和tag信息提取和写入，详细使用方法参考其主页上说明，下面简要的说说起安装方法和使用参数：
    \n\n
    1、安装方法
    \n\n
    直接下载其gz包，sneetchalizer-0.9.0是现在的最新版本。下载解包后可以看到：
    \n
    \nManifest:
    \n
    \n    README                - You're reading it now.  
    \n    LICENSE               - A copy of the GPL, under which sneetchalizer is released.  
    \n    CHANGES               - sneetchalizer's cvs/svn commit log.  
    \n    sneetchalizer         - The script itself.  
    \n    sneetchalizer.1       - The manpage for sneetchalizer.  
    \n    sneetchalizer.desktop - A KDE service menu for converting with Konqueror.  
    \n    install.rb            - A quick and dirty script to install the sneetchalizer.  
    \n
    \n
    \n如果有root权限，可以直接运行install.rb，其会将sneetchalizer拷贝到/usr/bin下，将sneetchalizer.1拷贝到/usr/share/man/man1下。
    \n\n
    2、参数解释
    \n\n
    不翻译了，都挺简单明了的，如下：
    \n
    \nXML/HTML代码
    \n
    \n    General options:  
    \n      
    \n    -h or --help  
    \n        Print quick or full usage details respectively.  
    \n    -r or --recursive  
    \n        Search directory arguments recursively for files to convert.  
    \n    -d or --delete  
    \n        delete input files after successful conversion. May not be safe yet!!!  
    \n    -v or --verbose  
    \n        makes sneetchalizer more chatty.  
    \n    -s or --show-output  
    \n        shows output from conversion tool.  
    \n    -p or --pretend  
    \n        don't convert anything. sneetchalizer will go through the motions and print out the commands it would run. Useful for preview- ing a complex command line to ensure it does what you intend. You should interpret this option's output with a grain of salt. For example, if you include the '--sanitize' option, the files will not really be renamed when using --pretend, and as such the command's output will not reflect that the filenames would be changed during an actual run.  
    \n    -t or --terminate  
    \n        terminate sneetchalizer options. This is useful if you have to convert '--coolDir' or '-groovySong.mp3'. This is the only option whose order on the command line is significant.  
    \n    -D ARG or --out-directory=ARG  
    \n        write all outfiles to a directory argument. This is useful if you want to (re)encode files directly to a mounted portable device.  
    \n    --strict and --pedantic  
    \n        many errors that sneetchalizer may encounter are recoverable, such as specifying a directory as argument that contains no files to convert, or conversion failures in general. By default the script will print an error message and move on to the next file. If you use '--strict' then sneetchalizer will bail out at the first sign of trouble except for tag errors. With '--pedantic' the script will stop even on tag errors.   
    \n    --stasis  
    \n        Preserve timestamp (mtime) of original file.  
    \n    --threads [N]  
    \n        Experimental. Use threads to create concurrent jobs. This option takes an optional integer argument which represents the number of threads to launch. The default is two. Preliminary tests suggest there is little advantage (and even diminishing returns) when setting this number greater than the number of cores/CPUs you have. Due to the asychronous nature of threads the --verbose and --show-output flags will be silently disabled and most screen output is supressed.   
    \n    --sanitize  
    \n        Removes ,, ;, :, ', ", %, @, #, and ` from filenames and tags.  
    \n    -n [FORMAT] or --rename[=FORMAT]  
    \n        rename all outfiles (and temporary wavs) according to FORMAT. FORMAT is a string with special designators to be pulled from the file tags. The following options are available:  
    \n      
    \n            * %t Song title  
    \n            * %b Album title  
    \n            * %n Track number  
    \n            * %a Artist name  
    \n            * %y Year  
    \n            * %g Genre  
    \n            * %c Comment field  
    \n      
    \n        Directories may be created with this command, as in "%b/%n - %t". The default value of FORMAT is "%n %t".   
    \n      
    \n    Bitrate/Quality/Compression options:  
    \n      
    \n    -b or --bitrate  
    \n        mp3/ogg/m4a bitrate.  
    \n    -q or --quality  
    \n        mp3/ogg quality.  
    \n      
    \n    quality and bitrate are passed directly to lame or oggenc depending on mp3 or ogg output format respectively. Both tools can handle either a bitrate or quality argument, so it is important to understand what values are valid for the underlying tool in your specific use case. faac will accept a bitrate argument, but not a quality argument. These options will be silently ignored for any output formats other than mp3, ogg or m4a. Make sure you know what you are doing if you decide to use both in one run, and read each tools manpage for valid values. If these options are omitted the tools builtin defaults are used (-q3 for oggenc and -q5 for lame).  
    \n      
    \n    -c or --compression  
    \n        flac/mac compression level.  
    \n      
    \n    this option allows you to pass a compression argument to flac and mac. See 'flac --help' and/or 'mac --help' if you don't know what this means.  
    \n      
    \n    Format Options:  
    \n      
    \n    --out=format  
    \n        output format. Default is wav.  
    \n    --in=format[,format..]  
    \n        input format(s). Default is wav.  
    \n      
    \n    Valid output formats are: "aac", "aif", "aifc", "aiff", "aiffc", "ape", "au", "cdr", "cdda", "copy", "flac", "m4a", "m4b", "mpc", "mp4", "mpp", "mp3", "mp2", "ofr", "ofs", "ogg", "snd", "spx", "tta", "wav", "wv". Valid input formats are all of the above plus "wma". You can specify multiple input formats using a comma: 'mp3,m4a,wma'. Input format is only neccesary when passing directory arguments, as file arguments are handled by context (read: file extension). The "copy" output option copies files directly, bypassing decoding/encoding steps (useful in conjunction with --rename).  
    \n      
    \n    Tagging Options:  
    \n      
    \n    --tt or --title  
    \n        Set 'title' tag.  
    \n    --ta or --artist  
    \n        Set 'artist' tag.  
    \n    --tl or --album  
    \n        Set 'album' tag.  
    \n    --ty or --year  
    \n        Set 'year' tag.  
    \n    --tc or --comment  
    \n        Set 'comment' tag.  
    \n    --tg or --genre  
    \n        Set 'genre' tag.  
    \n    --tn or --trackn  
    \n        Set 'track number' tag.  
    \n      
    \n    The short and long versions are different in an important way: Using the long version will clobber any existing tags. The short version will only set the tag if the existing tag has no value. Note that these tags will be placed in _every_ outfile during the run.  
    \n      
    \n    Alternative Encoder/Decoder Options:  
    \n      
    \n    --gogo  
    \n        use gogo to encode mp3 files.  
    \n    --bladeenc  
    \n        use bladeenc to encode mp3 files.  
    \n      
    \n    The default is still 'lame'. If 'lame' is not found, the script will search for one of these two encoders regardless if these options are passed or not.  
    \n      
    \n    Special Options:

    3、使用示例
    \n\n
    如下简要的写几个使用的示例：
    \n
    \n使用示例：
    \n
    \n    $ sneetchalizer song.mp3  
    \n      
    \n    The most simple possible example, creates 'song.wav'.  
    \n      
    \n    $ sneetchalizer --out=ogg --in=flac -q5 /some/music/dir  
    \n      
    \n    This example converts every flac file in '/some/music/dir' to ogg format at quality 5.  
    \n      
    \n    $ sneetchalizer -d --out=mp3 --in=ogg,m4a,wma -b 160 .  
    \n      
    \n    Converts every ogg, m4a, and wma file in the current directory to a 160 kbps constant bitrate mp3 file. The original files are deleted.  
    \n      
    \n    $ sneetchalizer --out=mp3 --out-optionhook="--preset extreme" /some/wavs  
    \n      
    \n    Here we encode every wav in '/some/wavs' to mp3 format passing '--preset extreme' directly to lame.  
    \n      
    \n    $ sneetchalizer --in=ogg --out=ogg --quality=1 norvegianWood.ogg /some/more/oggs  
    \n      
    \n    Using the same --in and --out format allows us to resample/encode the file at a different bitrate or quality. Note that this will overwrite the original file so only do this on a copy, or use '-D' to write files to another directory.  
    \n      
    \n    $ sneetchalizer --in=ogg --out=m4a -D /mnt/ipod/ /some/oggs  
    \n      
    \n    Here we re-encode some ogg files to m4a format and write them to our mounted iPod.

    生产环境下，需要对环境持续监控以尽快的发现问题，找到耗费资源较多的地方加以改进，比较常见的做法是使用moint或者God实时监控；另外，还可以定期分析日志找到特定的请求，虽然可以是shell来做这件事，但是何必再造轮子呢，因为我们已经有了Request log analyzer ：
    \n``简介：This is a simple command line tool to analyze request log files of both Rails andMerb. Its purpose is to find what actions are best candidates for optimization.This tool will parse all requests in the logfile and aggregate theinformation. Once it is finished parsing the log file, it will show therequests that take op most server time. Different metrics are used (cumulativetime, average time, blockers, DB time, etc)
    \n\n
    安装：gem sources -a http://gems.github.comsudo gem install wvanbergen-request-log-analyzer

    Ruby可以很方便的解析XML格式的文档，目前用的比较多的lib主要有三个，分别是：REXML, Hpricot, libxml-ruby，如下选取两个XML文档，分别使用这三个lib解析，感受下各自的速度和易用性。
    \n一、原料
    \n
    \n    posts.xml – Uses xml element for object (post) and xml attributes for object attributes
    \n    timeline.xml – Uses xml element for object (status) and child xml elements for attributes
    \n
    \n二、解析过程
    \n1、REXML
    \n\n
    Pros: In the standard library
    \nCons: Slow, I don’t like the name

    在Android中使用GoogleMap非常方便，但是有些小技巧或者注意事项你必须牢记，否则调试半天你也不会找到啥线索，浪费时间不说，更让你狂抓，以下技巧都是我在实际项目中遇到的，不断更新和维护，如果你有类似技巧，欢迎分享：
    \n
    （以下技巧是基于SDK 1.0的）
    \n
    一、申请Apikey，并放在正确的位置
    \n
    这个应该都知道，但是是申请得到的key放哪里很多人不知道，可以放在
    \n
    1、XML布局文件中
    \n
    <view android:id="@+id/mv"
    \n   class="com.google.android.maps.MapView"
    \n   android:layout_width="fill_parent"
    \n   android:layout_height="fill_parent"
    \n   android:layout_weight="1" 
    \n   android:apiKey="01Yu9W3X3vbpYT3x33chPXXX7U1Z6jy8WYZXNFA" 
    \n   />
    \n
    2、java中
    \n
            mMapView = new MapView(this, "01Yu9W3X3vbpYT3x33chPxxx7U1Z6jy8WYZXNFA");
    \n
    二、记得导入uses-library 
    \n
     由于1.0版本的修改，使得map包不再是默认的了，使用的时候需要在manifest中的application节点下加入
    \n
    <uses-library android:name="com.google.android.maps" /> 
    \n
    \n
    否则，你将遇到可恶的“java.lang.NoClassDefFoundError: ”，切记！
    \n
    三、需要给予一定的权限
    \n
    因为要使用GoogleMAP的service，所以需要
    \n<uses-permission android:name="android.permission.INTERNET"></uses-permission>
    \n
    如果需要GPS等应用，还需要
    \n
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
    \n
    四、Activity需要继承自MapActivity
    \n
    类似如下代码；
    \n
    package com.iceskysl.showmap;
    \n
    \nimport com.google.android.maps.MapActivity;
    \n
    \nimport android.os.Bundle;
    \n
    \npublic class ShowMap extends MapActivity {
    \n    /** Called when the activity is first created. */
    \n    @Override
    \n    public void onCreate(Bundle savedInstanceState) {
    \n        super.onCreate(savedInstanceState);
    \n        setContentView(R.layout.main);
    \n    }
    \n
    \n    @Override
    \n    protected boolean isRouteDisplayed() {
    \n        // TODO Auto-generated method stub
    \n        return false;
    \n    }
    \n}

  • Use Sphinx for text search.  --sometimes,you do have others chose.
    • \n
  • Use InnoDB for more crash resistant and faster writes.  --maybe it's right.
    • \n
  • Don't use textbook Rails ActiveRecord objects. Use New Relic to find exactly what is slow in your system. --yep
    • \n
  • Use memcache later so you find your database bottlenecks now. --this is very important.
    • \n
  • Use mongrel proctitle to find your slow queries. You are only as fast as your slowest queries. -maybe mongrel is not only chose,think about thin,ok?
    • \n
  • Use asynchronous job queuing to do work in parallel.  --yes,but sometimes crontab is enough.
    • \n
  • Use monitoring so you'll know when your site went down and why. --that's it,just do it.
    • \n
  • Learn by reading the source code, fixing problems, and submitting them back to the community.  --very userfull when you got some strange questions..
    • \n
  • Use new plugins. Old plugins can't be trusted. --and check chang histroy carefully.

    I konw,you can dev app and test it on the simulator,but if you had a real driver,G1,you can do debug on it,very great,here is the tips for this:\n
      \n    
    1. On your G1, go to Settings \"Arrow\" Applications \"Arrow\" Development \"Arrow\" [X] USB debugging 
      2. \n    
    2. Download this file: android_usb_windows.zip 
      3. \n    
    3. Unzip it to a folder 
      4. \n    
    4. Connect your G1 with your PC 
      5. \n    
    5. When it asks for driver location choose the unzipped folder and install the driver for it.
      6. \n    
    6. You'll see sth like "HTC Dream Composite ADB Interface" on success 
      7. \n    
    7. (Re)Start Eclipse 
      8. \n    
    8. Your G1 should now be listed in the DDMS-Perspective under Devices 
      9. \n    
    9. Go to the AndroidManifest.xml of your App and modify it to contain android:debuggable="true" in the <application ... >-Tag ,look like this:<application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="true">
      10. \n    
    10. Go Debug as usual.

    I konw,you can dev app and test it on the simulator,but if you had a real driver,G1,you can do debug on it,very great,here is the tips for this:
    \n
    \n    On your G1, go to Settings  Applications  Development  [X] USB debugging 
    \n    Download this file: android_usb_windows.zip 
    \n    Unzip it to a folder 
    \n    Connect your G1 with your PC 
    \n    When it asks for driver location choose the unzipped folder and install the driver for it.
    \n    You'll see sth like "HTC Dream Composite ADB Interface" on success 
    \n    (Re)Start Eclipse 
    \n    Your G1 should now be listed in the DDMS-Perspective under Devices 
    \n    Go to the AndroidManifest.xml of your App and modify it to contain android:debuggable="true" in the <application ... >-Tag ,look like this:<application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="true">
    \n    Go Debug as usual.

    \n1.DYNAMICALLY LOADING CONFIG FILES INTO AN ALREADY RUNNING GOD
    \n
    \n
    God allows you to load or reload configurations into an already running instance. There are a few things to consider when doing this:
    \n
      \n    
    • Existng Watches with the same name``` as the incoming Watches will be overidden by the new config.
      • \n    
    • All paths must be either absolute or relative to the path from which god was started.
      • \n
    \n
    To load a config into a running god, issue the following command:
    \n
    $ sudo god load path/to/config.god
    # god load /data/www/api/config/config_thin_api.god```\n
    Config files that are loaded dynamically can contain anything that a normal config file contains, however, global options such as God.pid_file_directory``` blocks will be ignored (and produce a warning in the logs).

    \n
    \n
    出错了，这边表貌似被MERGE用了，查了一下，果然是被rails_logs这个表MERGE着用了，那我直接truncate这个rails_logs试试看。
    \n
    mysql> truncate table  rails_logs;
    \n
    ERROR 1 (HY000): Can't create/write to file './iceskysl_beta_log/rails_logs.MRG' (Errcode: 17)
    \n
    \n
    呀，还是出错，文件不可写？Errcode: 17
    \n
    查下资料，原来：
    \n
    System error: 17 = File exists
    \n
    \n
    这咋回事，再查资料，原来.MRG是创建MERGE表的时候创建的，已经存在了。
    \n
    \n
    那就先把这个MERGE表干掉，再创建：
    \n
    先看下这个表是咋定义的：
    \n
    mysql>  show create table rails_logs;
    \n
    \n
    记录下SQL，接着drop掉。
    \n
    mysql> DROP  table rails_logs;
    \n
    Query OK, 0 rows affected (0.36 sec)
    \n
    \n
    再truncate我的目标表
    \n
    mysql> truncate table  rails_logs_081023;
    \n
    Query OK, 0 rows affected (4.22 sec)
    \n
    \n
    \n
    够快的，11042292条数据4S搞定，接着再创建下这个MERGE表，执行下上面记录的SQL就好了。
    \n
    \n
    最后确认下这表没啥问题：
    \n
    \n
    mysql> select count(id) from rails_logs;
    \n
    +-----------+
    \n
    | count(id) |

    \n
    +-----------+
    \n
    1 row in set (0.00 sec)
    \n

    OK，搞定，空间有了，天下太平了。

    \n
    问题：有一个拥有1亿条数据的表，只需要保留其中的5条，其他删除，如何做？
    \n
    这就需要用truncate table来搞定了，如下：
    \n
    select 5条数据 into #临时表 from 1亿条数据的牛X表
    \n
    truncate table 1亿条数据的牛X表
    \n
    --让它牛X，不到10毫秒干掉它。

    drop table #临时表

    然后有过了不记得多少时间，用了一个杭州的3G联通的卡，在G1手机上，没感觉啥时3G，只是相同资费，多点流量的感觉。
    \n\n
    然后再过了记不清多少时间，我自己在深圳电信营业厅买了一个电信3G无线上网卡，为啥选电信，也是大致比较了下3家，无疑这款不分漫游，不限流量按时间计费的无线网卡适合我的需求，只是电信的无线数据终端贵的离谱（好像也是市场价），淘宝了一个华为EC1261的，便宜不少，顺风送的，很快，第二天早上就送到了。
    \n\n
    插卡，连USB，测试，很顺利，本来比较担心mac下支持的不好，还好只碰到了“找不到设备”，Google一把，又乱找了一通，找到一个设置的地方，新建一个连接，号码#777,密码用户名card（都默认填写好了），点击连接就连上了。
    \n\n
    关了wifi，测试速度，比我预想的要好，参考图：
    \n\n\n
    下了一个100M的东西，花了7分多，速度在200K之上，还比较稳定，如下

    然后在测试下我本地wifi（电信4M带宽）速度，惨不忍睹，如下

    \n\n
    竟然不如无线上网卡的速度～
    \n\n
    用上无线上网卡，应该算进入3G时代了。
    \n\n
    PS：
    \n唯一不满意的地方就是这个无线网卡的设备有点大，我mac就2USB，被他占了一个后，另外一个耶盖住一点点，鼠标的USB插不进去了，难道还要买个USB分线器，冏～

    Example MySQL config file for large systems.
    \n\n
    This is for a large system with memory = 512M where the system runs mainly
    \n\n
    MySQL.
    \n\n
    You can copy this file to
    \n\n
    /etc/my.cnf to set global options,
    \n\n
    mysql-data-dir/my.cnf to set server-specific options (in this
    \n\n
    installation this directory is /var/lib/mysql) or
    \n\n
    ~/.my.cnf to set user-specific options.
    \n\n
    In this file, you can use all long options that a program supports.
    \n\n
    If you want to know which options a program supports, run the program
    \n\n
    with the "--help" option.
    \n\n
    The following options will be passed to all MySQL clients
    \n\n
    [client]
    \nport            = 3306
    \nsocket          = /var/lib/mysql/mysql.sock

    By default, the wait_timeout value is 28800. Unless you want MySQL to keep waiting for 28800 seconds (480 minutes or 8 hours),
    \n\n
    please decrease its value according to your application needs.

    Don't listen on a TCP/IP port at all. This can be a security enhancement,
    \n\n
    if all processes that need to connect to mysqld run on the same host.
    \n\n
    All interaction with mysqld must be made via Unix sockets or named pipes.

    \n控件足：Balsamiq Mockups 软件包括 50 多个控件， 70 多个图标。基本自带了所有常用的小控件，并在导航处进行分类；图标设计赏心悦目。要是 Balsamiq Mockups 允许用户导入自定义的控件就更好了，当然现有的也足够了 -
    \n新风格：让人眼前一亮的涂鸦风格，很能还原手绘效果；
    \n可中文：在菜单栏 View 里将 Use System Fonts 勾上，就能完美支持中文输入（注：非 Balsamiq Mockups 中文版）；
    \n其它点：Balsamiq Mockups 使用 xml 记录，方便移植、二次利用；可导出为 png 格式图片。
    \n\n
    另外还有跨平台与多版本两个优点：
    \n跨平台：Balsamiq Mockups 基于 Air ，因此能同时在 Windows、Mac OS 及 Linux 下使用；
    \n多版本：包括桌面版本，以及集成于 Confluence、JIRA、XWiki、FogBugz 中的版本
    \n\n
    软件可以从其网站上下载，其中桌面版本售价是$79。但作者非常厚道，提供了几种免费使用的方式：http://www.balsamiq.com/products/mockups/desktop

    配置
    \n\n
    那么应该怎样来配置成我喜欢的颜色呢？下面我们就来详细说一些这些配置。
    \n\n
    ~/.bash_profile是bash shell中当前登录用户的配置文件。bash是“终端”中默认的shell。
    \n\n
    alias ls=”ls -G”是给”ls -G”起了一个别名，当执行ls时，就相当于执行了ls -G。
    \n\n
    CLICOLOR是用来设置是否进行颜色的显示。CLI是Command Line Interface的缩写。
    \nLSCOLORS是用来设置当CLICOLOR被启用后，各种文件类型的颜色。LSCOLORS的值中每两个字母为一组，分别设置某个文件类型的文字颜色和背景颜色。LSCOLORS中一共11组颜色设置，按照先后顺序，分别对以下的文件类型进行设置：
    \n\n
    directory
    \nsymbolic link
    \nsocket
    \npipe
    \nexecutable
    \nblock special
    \ncharacter special
    \nexecutable with setuid bit set
    \nexecutable with setgid bit set
    \ndirectory writable to others, with sticky bit
    \ndirectory writable to others, without sticky bit
    \nLSCOLORS中，字母代表的颜色如下：
    \n\n
    a 黑色
    \nb 红色
    \nc 绿色
    \nd 棕色
    \ne 蓝色
    \nf 洋红色
    \ng 青色
    \nh 浅灰色
    \nA 黑色粗体
    \nB 红色粗体
    \nC 绿色粗体
    \nD 棕色粗体
    \nE 蓝色粗体
    \nF 洋红色粗体
    \nG 青色粗体
    \nH 浅灰色粗体
    \nx 系统默认颜色
    \n所以，如果我们想把目录显示成红色，就可以把LSCOLORS设置为bxfxaxdxcxegedabagacad就可以了

    现就相关事宜申明如下：
    \n一、我开发的所有程序都没有侵犯到用户的隐私。\n\n在这个应用中，申请的全部权限为：\n
    <uses-permission android:name=\"android.permission.INTERNET\" />
    \n
    <uses-permission android:name=\"android.permission.ACCESS_NETWORK_STATE\" />
    \n
    <uses-permission android:name=\"android.permission.WRITE_EXTERNAL_STORAGE\" />

    <uses-permission android:name=\"android.permission.READ_PHONE_STATE\" />
    \n
    <uses-permission android:name=\"android.permission.ACCESS_COARSE_LOCATION\" />
    \n懂点Android技术的都知道，这些权限都是为了让该软件的功能，能够正常工作所必须的权限（连接网络，获取网络状态，下载壁纸时读写SD卡，设置壁纸，读取手机状态）和Admob的广告精准推送所需要的权限（位置信息，读取手机状态）。\n至于获取用户浏览历史记录、短信、语音邮件密码的这些明显侵犯用户隐私的行为，完全是子虚乌有。一方面并没要申请相关的权限；另一方面我还真不知道怎样获取这些敏感信息。另外，admob的精准广告服务中可能是会针对用户的地理位置等信息推送更准确的广告服务。\n关于这款应用能获取的设备标识号是用来区分设备的唯一性，免去用户注册的麻烦，而能给用户提供收藏图片的功能；而诸如获取手机屏幕大小是为了能够智能适配合适的图片。在这些设备信息中，请问哪一条会侵犯到用户的隐私。\n另外说我可以获取浏览历史信息，这简直就是个天大的笑话。如果懂一点程序的就会知道，要获取浏览器信息必须在程序里申请com.android.browser.permission.READ_HISTORY_BOOKMARKS权限。我的程序完全没有获取到权限，怎么能够获取到历史信息，真是笑话！！！\n\n二、Android手机的权限管理，在任何没有刷过第三方rom的手机上是很严格的。\n Android手机的权限管理，在任何没有刷过第三方rom的手机上是很严格的，在没有相关权限的情况下，要获取那些信息，是完全不可能的。就算是被刷过Rom的手机，也只有具有该ROM制作人的加密签名的程序，才能完成一些不安全的操作。\n我所需要的权限在用户安装的时候会很明确的告诉用户，下面我就给大家展示一下我应用申请的权限和另外一个著名的壁纸的应用background和一款管理短信的应用申请的权限。\n\n我的软件需要的权限：\n\"\"\n\n看看background（另外一款壁纸的应用）申请的权限：\n\"\"\n\nHandcent SMS申请的权限：\n\n\"\"\n\n短信有短信的权限，联系人有联系人的权限，我都没要申请，请问我如何获取相关的信息。\n\n三、应用主要面向外国用户，但绝对没有获取那些高敏感度的隐私信息！\n\n该应用主要面向外国用户（国内由于网络原因无法正常使用），连接服务器端能够获取到精确适配终端的图片，这是一款非常有用，也深受用户喜爱的应用。它确实拥有数量众多（几百万）的用户，但绝对没有获取那些高敏感度的隐私信息！我每天都收到很多用户的反馈邮件告诉我这个软件多么棒，给他们带来多少乐趣！\n\n四、我本人始终与业界同仁一道，希望建立诚实守信、和谐共生的Android产业生态系统。\n\n随着Android开放性操作平台手机的广泛使用，其应用软件开发市场正呈现蓬勃发展景象。对于提醒用户警惕来自手机上的威胁，我本人向来都是强烈支持的！本人一直始终与业界同仁一道，一直为共建诚实守信、和谐共生的Android产业生态系统而努力，将力量专注于用户需求和技术创新，创造更被用户喜欢的软解，并致力于推动手机应用软件产业持续健康发展。\n\n在此，本人郑重申明，该应用没有获取任何诸如“浏览历史记录，短信，语音邮件密码等”这种高敏感度的信息，并和国外的原作者取得联系，让其修正自己的言论并发布公开道歉，同时对于这种不负责任的言论和评价观点，对我及与我相关的应用进行不负责任的报道造成的影响给予补偿，我将保留追究其法律责任的权利。\n\nps：\n\n如果您有其他的疑问或者问题，欢迎你在我sina微博客（http://t.sina.com.cn/iceskysl）或者sohu微博（http://t.sohu.com/iceskysl）给我沟通！\n

    \n\n
    在看完这条消息后，我立马检查了所有代码，防止这款应用在我不知情的情况下，被他人加入恶意代码，但我一无所获。
    \n现就相关事宜申明如下：
    \n一、我开发的所有程序都没有侵犯到用户的隐私。
    \n\n
    在这个应用中，申请的全部权限为：
    \n<uses-permission android:name="android.permission.INTERNET" />
    \n<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

    \n关于这款应用能获取的设备标识号是用来区分设备的唯一性，免去用户注册的麻烦，而能给用户提供收藏图片的功能；而诸如获取手机屏幕大小是为了能够智能适配合适的图片。在这些设备信息中，请问哪一条会侵犯到用户的隐私。
    \n另外说我可以获取浏览历史信息，这简直就是个天大的笑话。如果懂一点程序的就会知道，要获取浏览器信息必须在程序里申请com.android.browser.permission.READ_HISTORY_BOOKMARKS权限。我的程序完全没有获取到权限，怎么能够获取到历史信息，真是笑话！！！
    \n\n
    二、Android手机的权限管理，在任何没有刷过第三方rom的手机上是很严格的。
    \n Android手机的权限管理，在任何没有刷过第三方rom的手机上是很严格的，在没有相关权限的情况下，要获取那些信息，是完全不可能的。就算是被刷过Rom的手机，也只有具有该ROM制作人的加密签名的程序，才能完成一些不安全的操作。
    \n我所需要的权限在用户安装的时候会很明确的告诉用户，下面我就给大家展示一下我应用申请的权限和另外一个著名的壁纸的应用background和一款管理短信的应用申请的权限。
    \n\n
    我的软件需要的权限：
    \n\n
    看看background（另外一款壁纸的应用）申请的权限：
    \n\n
    Handcent SMS申请的权限：
    \n\n\n
    短信有短信的权限，联系人有联系人的权限，我都没要申请，请问我如何获取相关的信息。
    \n\n
    三、应用主要面向外国用户，但绝对没有获取那些高敏感度的隐私信息！
    \n\n
    该应用主要面向外国用户（国内由于网络原因无法正常使用），连接服务器端能够获取到精确适配终端的图片，这是一款非常有用，也深受用户喜爱的应用。它确实拥有数量众多（几百万）的用户，但绝对没有获取那些高敏感度的隐私信息！我每天都收到很多用户的反馈邮件告诉我这个软件多么棒，给他们带来多少乐趣！
    \n\n
    四、我本人始终与业界同仁一道，希望建立诚实守信、和谐共生的Android产业生态系统。
    \n\n
    随着Android开放性操作平台手机的广泛使用，其应用软件开发市场正呈现蓬勃发展景象。对于提醒用户警惕来自手机上的威胁，我本人向来都是强烈支持的！本人一直始终与业界同仁一道，一直为共建诚实守信、和谐共生的Android产业生态系统而努力，将力量专注于用户需求和技术创新，创造更被用户喜欢的软解，并致力于推动手机应用软件产业持续健康发展。
    \n\n
    在此，本人郑重申明，该应用没有获取任何诸如“浏览历史记录，短信，语音邮件密码等”这种高敏感度的信息，并和国外的原作者取得联系，让其修正自己的言论并发布公开道歉，同时对于这种不负责任的言论和评价观点，对我及与我相关的应用进行不负责任的报道造成的影响给予补偿，我将保留追究其法律责任的权利。

    \nupdate：
    \n写完申明后，去看消息出处看到其竟然做了修改，我早料到其会做相关的行为，所有早些时候截了屏幕如下：
    \n\n\n
    而现在的文章被修改为：
    \n\n\n
    看我用鼠标标识的地方，对关键信息进行了修改，感兴趣的人可以去 http://mobile.venturebeat.com/2010/07/28/android-wallpaper-app-that-steals-your-data-was-downloaded-by-millions/ 查看原文，对于这种标题党用子虚乌有的事情炒作，等消息传播后再修改自己的内容算什么行为！而对国内部分媒体在传播时不但不对真实性进行验证，还添油加醋，歪曲意思的报道，我非常无奈（看到有人还说可以获取信用卡信息，还加密传输，我实在无语）。
    \n\n
    按照我个人的感觉，他们应该紧接着要开始拿这个事件来炒作自己的产品了，我个人懒得去关注，如果有人发现有人借此炒作自己的产品，请帮忙分析分析，看看到底是什么人用这样手法。
    \n\n
    再次update！！！
    \n\n
    通过email和mylookout的人取得联系，说明我取得诸如设备号，手机屏幕大小是为了更智能的给设备适配图片，而获取部分的sim卡号是后来用户反馈说自己换了手机还想使用之前的收藏记录才使用的，这些信息只在该应用中使用，并没提供给任何第三方！
    \n\n
    同时让其确认venturebeat上文章中说到的获取浏览器历史，短信息，密码等高敏感性信息是否是他们说的还是写文章的人自己写的（Lots of my users send me the email ask me why I collect their text message and voicemail passward, I just want to make sure whether you and your ceo said that  I collected browsing history,text message ,voicemail passward during the meeting.）。
    \n\n
    其cto给我回复说他们没有说过我的应用获取过诸如text messages or browsing history这些信息（ We never stated that the wallpaper applications gathered users text messages or browsing history.），是媒体在撰写和传播的时候错误报道了（A member of the press misreported our research and he has since corrected it. ）。

    1. google就前段时间将应用暂停和我一起分析了这个应用，今天发来调查的结果：
    \n\n
    Our investigation has concluded that there's no obvious malicious code in your apps, though the implementation accesses data that it doesn't need to.  We've restored your apps (and they'll be available on Market again once you publish them), and are looking forward to seeing them updated to use ANDROID_ID.  We are likely to make a statement about this issue this week--I'll let you know.
    \n\n
    我早就说过，我配合调查，我把代码提供给他们，google也做出了公正的评判，另外也给我提了一些建议（ANDROID_ID）。
    \n\n
    2. 当时写这篇报道的venturebeat记者Dean Takahashi发来了mail，为自己犯的错误道歉，并道歉该事带来的恶劣影响，会再写一篇文章澄清这个事情以消除影响。

    这个世界有意思，多大的idea都可以做成网站，以前看过缩址的网站，现在有看到一个省份标识的网站， Gravatars，看他的介绍：
    \nA gravatar, or globally recognized avatar, is quite simply an avatar image that follows you from weblog to weblog appearing beside your name when you comment on gravatar enabled sites. Avatars help identify your posts on web forums, so why not on weblogs?
    \n看明白了么，就是一个你输入自己的Email，然后上传自己的图片标识，然后在其他支持 Gravatars的网站（blog居多）中发表评论的时候输入自己的Email地址，就可以在Gravatars上找到其对应的图片来显示了。
    \n\n
    这确实是个不错的Idea，相当简单，但是也做得有声有色的，有点意思。
    \n\n
    使用也很方便，其在“How the URL is constructed”上介绍了其URL的组成，中可以这么使用（来源Gravatars on Rails）：
    \n\n
    <!--more-->
    \n\n
    1、首先在`application_helper.rb中增加一个helper方法
    \n
    \nRuby代码
    \n
    \n    require 'digest/md5'    
    \n    #增加一个Helper方法    
    \n    def gravatar_url_for(email, options = {})        
    \n       url_for({ :gravatar_id => Digest::MD5.hexdigest(email), :host => 'www.gravatar.com',          
    \n                :protocol => 'http://', :only_path => false, :controller => 'avatar.php'        
    \n           }.merge(options))      
    \n    end    
    \n
    \n
    \n 
    \n\n
    2、然后就可以在view里面直接使用了
    \n
    \nRuby代码
    \n
    \n    # plain old gravatar url      
    \n    <%= gravatar_url_for 'iceskysl@gmail.com' %>        
    \n        
    \n    # gravatar url with a rating threshold       
    \n    <%= gravatar_url_for 'iceskysl@gmail.com', { :rating => 'R' } %>        
    \n        
    \n    # show the avatar       
    \n    <%= image_tag(gravatar_url_for 'iceskysl@gmail.com')%>       
    \n        
    \n    # show the avatar with size specified, in case it's served slowly      
    \n    <%= image_tag(gravatar_url_for('iceskysl@gmail.com'), { :width => 80, :height => 80 }) %>      
    \n      
    \n    # link the avatar to some/url    
    \n    <%= link_to(image_tag(gravatar_url_for 'iceskysl@gmail.com'), 'some/url')%>    
    \n
    \n
    \nPS：果然不出所料，还有Gem可以使用" Ruby Avatar Gem"

    \r\n
    Ruby代码
    \r\n
      \r\n\t
    1. before_filter :set_wap_content_type, :only => :wap  
      2. \r\n\t

      5. \r\n\t
    5. end  
      6. \r\n
    \r\n
    \r\n2、添加一个WAP的全局布局模板app/views/layouts/wap.rhtm\r\n
    \r\n
    XML/HTML代码
    \r\n
      \r\n\t
    1. <?xml version=”1.0″?>  
      2. \r\n\t
    2. <!DOCTYPE wml PUBLIC “-//WAPFORUM//DTD WML 1.1//EN” “http://www.wapforum.org/DTD/wml_1.1.xml”>  
      3. \r\n\t
    3. <wml>  
      4. \r\n\t
    4. <card title=”<%= @title %>”>  
      5. \r\n\t
    5. <p align=”center”>  
      6. \r\n\t
    6. <%= @content_for_layout %>

      8. \r\n\t
    8. </card>  
      9. \r\n\t
    9. </wml>  
      10. \r\n
    \r\n
    \r\n3、在我的controller中（index）中增加一个action用来响应WAP请求。\r\n
    \r\n
    Ruby代码
    \r\n
      \r\n\t
    1. def wap  
      2. \r\n\t
    2.   @title = \"San Francisco Sailing Weather\"  
      3. \r\n\t
    3.   render(:layout => \"wml\")  
      4. \r\n\t
    4. end  
      5. \r\n
    \r\n
    \r\n4、添加相应的view模板app/views/index/wap.rhtml\r\n
    \r\n
    XML/HTML代码
    \r\n
      \r\n\t
    1. <%= link_to 'NOAA Marine Forecast', { :controller => '/marine/forecast', :action => 'wap' } %><br/>  
      2. \r\n\t
    2. <%= link_to 'Wind Readings', { :controller => '/marine/wind', :action => 'wap' } %><br/>  
      3. \r\n\t
    3. <%= link_to 'Current Predictions', { :controller => '/marine/tide', :action => 'wap' } %>  
      4. \r\n
    \r\n
    \r\n \r\n\r\n二、使用Rails2支持的多模板类型支持\r\n\r\n在Rails2以后，Rails支持多种格式的输出，比如Html，RSS，JS等，当然你还可以定制自己的格式，比如我们这里说的WML，Iphone等，使用起来更简单、自然。\r\n\r\n1、添加MIME格式支持\r\n\r\n在config/environment.rb中增加MIME的格式支持，方式如下：\r\n
    \r\n
    Ruby代码
    \r\n
      \r\n\t
    1. Mime::Type.register \"text/vnd.wap.wml\", :wml  
      2. \r\n
    \r\n
    \r\n
    \r\n2、判断请求类型```\r\n
    \r\n
    Ruby代码
    \r\n
      \r\n\t
    1. # application.rb  
      2. \r\n\t
    2. before_filter :adjust_format_for_beta  
      3. \r\n\t
    3.   
      4. \r\n\t
    4. ...  
      5. \r\n\t
    5.   
      6. \r\n\t
    6. def adjust_format_for_beta  
      7. \r\n\t
    7.   request.format = :beta if beta_request?   
      8. \r\n\t
    8. end  
      9. \r\n\t
    9.   
      10. \r\n\t
    10. def beta_request?  
      11. \r\n\t
    11.   return (request.subdomains.first == \"beta\" || params[:format] == \"beta\")  
      12. \r\n\t
    12. end  
      13. \r\n
    \r\n
    \r\n
    \r\n3、添加相应的view代码比较简单，就是写XML或者WML模板show.wml.erb```\r\n
    \r\n
    XML/HTML代码
    \r\n
      \r\n\t
    1. xml.instruct! :xml, :version => \"1.0\"  
      2. \r\n\t
    2. xml.wml \"xml:lang\" => \"en-gb\" do  
      3. \r\n\t
    3.   xml.card :title => \"My title here\" do  
      4. \r\n\t
    4.     xml.p \"Something interesting here\"  
      5. \r\n\t
    5.     xml.p \"Something else interesting here.\"  
      6. \r\n\t
    6.   end  
      7. \r\n\t
    7. end  
      8. \r\n
    \r\n
    \r\n
    \r\n4、添加输出类型支持```\r\n
    \r\n
    Ruby代码
    \r\n
      \r\n\t
    1. def index  
      2. \r\n\t
    2.   respond_to do |format|  
      3. \r\n\t
    3.     format.html  
      4. \r\n\t
    4.     format.wml  
      5. \r\n\t
    5.   end  
      6. \r\n\t
    6. end  
      7. \r\n
    \r\n
    \r\n
    \r\n以上两中方式，我个人更加喜欢Rails2的多模板支持模式，更加自然和清晰。实用工具：wmlbrowser add-on for Firefox ：可以在FF下直接查看WML网页Opera：支持WML格式显示```\r\n参考资文章：\r\n\r\n1、Making your Rails app mobile with WAP and WML\r\n2、Ruby on Rails (and some WAP)\r\n3、Redesign your site in place using Rails custom mime types\r\n\r\n参考资料：\r\n\r\nW3schools WAP tutorial\r\nW3schools WML reference\r\nWeb based WAP Emulator\r\n\r\n ", "created_at"=>2008-07-01 06:51:55 UTC, "updated_at"=>2012-06-24 15:46:46 UTC, "body_html"=>"
    Rails在WEB开发中独树一帜，取得相当大的成功，但是其内核中尚未支持WML，于是查找了一些资料，如果你使用Rails开发的系统向添加WAP支持，这或许对你有用。

    总的来看，有两个方式来实现对WML的支持，单独支持和整合支持，下面详细的说。
    \n\n
    一、按照一般方式支持
    \n\n

    \n      @headers["Content-Type"] = “text/vnd.wap.wml; charset=iso-8859-1″  
    \n    end  
    \n
    \n
    \n2、添加一个WAP的全局布局模板app/views/layouts/wap.rhtm
    \n
    \nXML/HTML代码
    \n
    \n    <?xml version=”1.0″?>  
    \n    <!DOCTYPE wml PUBLIC “-//WAPFORUM//DTD WML 1.1//EN” “http://www.wapforum.org/DTD/wml_1.1.xml”>  
    \n    <wml>  
    \n    <card title=”<%= @title %>”>  
    \n    <p align=”center”>  
    \n    <%= @content_for_layout %>  
    \n    </p>  
    \n    </card>  
    \n    </wml>  
    \n
    \n
    \n3、在我的controller中（index）中增加一个action用来响应WAP请求。
    \n
    \nRuby代码
    \n
    \n    def wap  
    \n      @title = "San Francisco Sailing Weather"  
    \n      render(:layout => "wml")  
    \n    end  
    \n
    \n
    \n4、添加相应的view模板app/views/index/wap.rhtml
    \n
    \nXML/HTML代码
    \n
    \n    <%= link_to 'NOAA Marine Forecast', { :controller => '/marine/forecast', :action => 'wap' } %><br/>  
    \n    <%= link_to 'Wind Readings', { :controller => '/marine/wind', :action => 'wap' } %><br/>  
    \n    <%= link_to 'Current Predictions', { :controller => '/marine/tide', :action => 'wap' } %>  
    \n
    \n
    \n 
    \n\n
    二、使用Rails2支持的多模板类型支持
    \n\n
    在Rails2以后，Rails支持多种格式的输出，比如Html，RSS，JS等，当然你还可以定制自己的格式，比如我们这里说的WML，Iphone等，使用起来更简单、自然。
    \n\n
    1、添加MIME格式支持
    \n\n
    在config/environment.rb中增加MIME的格式支持，方式如下：
    \n
    \nRuby代码
    \n
    \n    Mime::Type.register "text/vnd.wap.wml", :wml  
    \n
    \n
    \n
    \n2、判断请求类型
    \n<div class="codeText">
    \n<div class="codeHead">Ruby代码</div>
    \n<ol class="dp-rb" start="1">
    \n    <li class="alt"><span><span class="comment"># application.rb</span><span>  </span></span></li>
    \n    <li><span>before_filter <span class="symbol">:adjust_format_for_beta</span><span>  </span></span></li>
    \n    <li class="alt"><span>  </span></li>
    \n    <li><span>...  </span></li>
    \n    <li class="alt"><span>  </span></li>
    \n    <li><span><span class="keyword">def</span><span> adjust_format_for_beta  </span></span></li>
    \n    <li class="alt"><span>  request.format = <span class="symbol">:beta</span><span> </span><span class="keyword">if</span><span> beta_request?   </span></span></li>
    \n    <li><span><span class="keyword">end</span><span>  </span></span></li>
    \n    <li class="alt"><span>  </span></li>
    \n    <li><span><span class="keyword">def</span><span> beta_request?  </span></span></li>
    \n    <li class="alt"><span>  <span class="keyword">return</span><span> (request.subdomains.first == </span><span class="string">"beta"</span><span> || params[</span><span class="symbol">:format</span><span>] == </span><span class="string">"beta"</span><span>)  </span></span></li>
    \n    <li><span><span class="keyword">end</span><span>  </span></span></li>
    \n</ol>
    \n</div>
    \n<pre style="font-size: 90%;">
    \n<strong>3、添加相应的view代码</strong>比较简单，就是写XML或者WML模板<strong>show.wml.erb</strong>
    \n
    \nXML/HTML代码
    \n
    \n    xml.instruct! :xml, :version => "1.0"  
    \n    xml.wml "xml:lang" => "en-gb" do  
    \n      xml.card :title => "My title here" do  
    \n        xml.p "Something interesting here"  
    \n        xml.p "Something else interesting here."  
    \n      end  
    \n    end  
    \n
    \n
    \n
    \n4、添加输出类型支持
    \n<div class="codeText">
    \n<div class="codeHead">Ruby代码</div>
    \n<ol class="dp-rb" start="1">
    \n    <li class="alt"><span><span class="keyword">def</span><span> index  </span></span></li>
    \n    <li><span>  respond_to <span class="keyword">do</span><span> |format|  </span></span></li>
    \n    <li class="alt"><span>    format.html  </span></li>
    \n    <li><span>    format.wml  </span></li>
    \n    <li class="alt"><span>  <span class="keyword">end</span><span>  </span></span></li>
    \n    <li><span><span class="keyword">end</span><span>  </span></span></li>
    \n</ol>
    \n</div>
    \n<pre style="font-size: 90%;">
    \n以上两中方式，我个人更加喜欢Rails2的多模板支持模式，更加自然和清晰。<strong>实用工具：</strong><a href="http://addons.mozilla.org/firefox/addon/62">wmlbrowser add-on for Firefox</a> ：可以在FF下直接查看WML网页<a href="http://cn.opera.com/">Opera</a>：支持WML格式显示

    \n找到一个msysgit ，按照里面的说明下载安装就OK了，下面看看如何使用：
    \n-----------------使用---------------
    \n好,下面来个简单教程.标准的 git 教程是行不通的(要加些东西),因为这是windows.主要是没有用户信息.好我的git安装在 c:\\git 以下为命令行.
    \n
    \n1.创建git的数据库
    \nC:\\Git\\bin>git init-db
    \n\n
    2.生成一个文件xxx并加入到git中
    \nC:\\Git\\bin>echo hello > xxx
    \nC:\\Git\\bin>git add xxx
    \n\n
    3.提交[以上两步与标准教程还是一样的,关键是这一步]
    \nC:\\Git\\bin>set home=c:\\
    \nC:\\Git\\bin>git config --global user.name "clq"
    \nC:\\Git\\bin>git commit -m "test"
    \n\n
    一共三个命令,其中第1个是设置用户路径,第2个是设置用户名.而且是每次打开dos命令行后都要有这两个命令,当然你可以写成 bat 文件.第3个才是提交,不能直接写 git commit 因为这个版本好象一定要有注释,那个 "test" 就是我加的注释了.
    \n\n
    4.改一下xxx文件
    \necho world >> xxx
    \n\n
    5.查看一下它和我们原来对比的有什么不同
    \nC:\\Git\\bin>git diff
    \n\n
    结果如下
    \ndiff --git a/xxx b/xxx
    \nindex 907cd4b..360c7f4 100644
    \n--- a/xxx
    \n+++ b/xxx
    \n@@ -1 +1,2 @@
    \nhello
    \n+world
    \n(END)
    \n\n
    用过cvs的都明白了吧.另外这个显示的还得退出,退出命令和vi一样
    \n提交可以用一个命令来完成
    \ngit commit -m "" -a xxx
    \n\n
    省去git add
    \n\n
    C:\\Git\\bin>git show xxx
    \n查看最近一次提交的信息.
    \n\n
    C:\\Git\\bin>git commit -a -m"aa"
    \n\n
    提交全部更改过的文件.

    12.     shows output from conversion tool.  
      13. \r\n\t
    13. -p or --pretend  
      14. \r\n\t
    14.     don't convert anything. sneetchalizer will go through the motions and print out the commands it would run. Useful for preview- ing a complex command line to ensure it does what you intend. You should interpret this option's output with a grain of salt. For example, if you include the '--sanitize' option, the files will not really be renamed when using --pretend, and as such the command's output will not reflect that the filenames would be changed during an actual run.  
      15. \r\n\t
    15. -t or --terminate  
      16. \r\n\t
    16.     terminate sneetchalizer options. This is useful if you have to convert '--coolDir' or '-groovySong.mp3'. This is the only option whose order on the command line is significant.  
      17. \r\n\t
    17. -D ARG or --out-directory=ARG  
      18. \r\n\t
    18.     write all outfiles to a directory argument. This is useful if you want to (re)encode files directly to a mounted portable device.  
      19. \r\n\t
    19. --strict and --pedantic  
      20. \r\n\t
    20.     many errors that sneetchalizer may encounter are recoverable, such as specifying a directory as argument that contains no files to convert, or conversion failures in general. By default the script will print an error message and move on to the next file. If you use '--strict' then sneetchalizer will bail out at the first sign of trouble except for tag errors. With '--pedantic' the script will stop even on tag errors.   
      21. \r\n\t
    21. --stasis  
      22. \r\n\t
    22.     Preserve timestamp (mtime) of original file.

    27. -n [FORMAT] or --rename[=FORMAT]  
      28. \r\n\t
    28.     rename all outfiles (and temporary wavs) according to FORMAT. FORMAT is a string with special designators to be pulled from the file tags. The following options are available:

    \r\n
    使用示例：
    \r\n
      \r\n\t
    1. $ sneetchalizer song.mp3  
      2. \r\n\t
    2.   
      3. \r\n\t
    3. The most simple possible example, creates 'song.wav'.  
      4. \r\n\t
    4.   
      5. \r\n\t
    5. $ sneetchalizer --out=ogg --in=flac -q5 /some/music/dir  
      6. \r\n\t
    6.   
      7. \r\n\t
    7. This example converts every flac file in '/some/music/dir' to ogg format at quality 5.  
      8. \r\n\t
    8.   
      9. \r\n\t
    9. $ sneetchalizer -d --out=mp3 --in=ogg,m4a,wma -b 160 .  
      10. \r\n\t
    10.   
      11. \r\n\t
    11. Converts every ogg, m4a, and wma file in the current directory to a 160 kbps constant bitrate mp3 file. The original files are deleted.  
      12. \r\n\t
    12.   
      13. \r\n\t
    13. $ sneetchalizer --out=mp3 --out-optionhook=\"--preset extreme\" /some/wavs  
      14. \r\n\t
    14.   
      15. \r\n\t
    15. Here we encode every wav in '/some/wavs' to mp3 format passing '--preset extreme' directly to lame.  
      16. \r\n\t
    16.   
      17. \r\n\t
    17. $ sneetchalizer --in=ogg --out=ogg --quality=1 norvegianWood.ogg /some/more/oggs  
      18. \r\n\t
    18.   
      19. \r\n\t
    19. Using the same --in and --out format allows us to resample/encode the file at a different bitrate or quality. Note that this will overwrite the original file so only do this on a copy, or use '-D' to write files to another directory.  
      20. \r\n\t
    20.   
      21. \r\n\t
    21. $ sneetchalizer --in=ogg --out=m4a -D /mnt/ipod/ /some/oggs  
      22. \r\n\t
    22.   
      23. \r\n\t
    23. Here we re-encode some ogg files to m4a format and write them to our mounted iPod.   
      24. \r\n

    \r\n4、注意事项\r\n\r\n本脚本只是粘合剂，其他的tool还是需要另外安装的。\r\n\r\n其他信息请参考其主页说明,如果您有这个方面的问题或经验，欢迎和我讨论。\r\n\r\n\r\n\r\n\r\n ", "created_at"=>2008-10-09 02:49:27 UTC, "updated_at"=>2012-06-24 15:46:47 UTC, "body_html"=>"
    前几天写了“采用Ruby提取MP3的metadata信息”后，就在寻找成熟的Ruby代码做差不多的事情，今天找到一个sneetchalizer，仔细的看了下，非常强大。
    \n\n\n
    sneetchalizer其实只是个粘合剂，因为在*unix下，audio格式转换的lib已经非常丰富和成熟，例如lame,gogo,bladeenc,mplayer等等就非常好用；另外，关于audio的tag信息和metadata信息的提取也有比较成熟的lib了，类似id3lib-ruby library,wmainfo-rb library,ruby-ogginfo library等等。而sneetchalizer只是把这些tools粘合起来。
    \n\n
    其支持的格式有:'aac' 'aif' 'aifc' 'aiff' 'aiffc' 'ape' 'au' 'caf' 'cdda' 'cdr' 'copy' 'fap' 'flac' 'gsm''ircam' 'm4a' 'm4b' 'mat' 'mat4' 'mat5' 'mp2' 'mp3' 'mp4' 'mpc' 'mpp' 'nist' 'ofr''ofs' 'ogg' 'paf' 'pvf' 'raw' 'sd2' 'sds' 'sf' 'snd' 'spx' 'svx' 'tta' 'voc''vox' 'w64' 'wav' 'wma' 'wv' 'xi'
    \n\n
    使用sneetchalizer可以实现audio文件的格式转换和tag信息提取和写入，详细使用方法参考其主页上说明，下面简要的说说起安装方法和使用参数：
    \n\n
    1、安装方法
    \n\n
    直接下载其gz包，sneetchalizer-0.9.0是现在的最新版本。下载解包后可以看到：
    \n
    \nManifest:
    \n
    \n    README                - You're reading it now.  
    \n    LICENSE               - A copy of the GPL, under which sneetchalizer is released.  
    \n    CHANGES               - sneetchalizer's cvs/svn commit log.  
    \n    sneetchalizer         - The script itself.  
    \n    sneetchalizer.1       - The manpage for sneetchalizer.  
    \n    sneetchalizer.desktop - A KDE service menu for converting with Konqueror.  
    \n    install.rb            - A quick and dirty script to install the sneetchalizer.  
    \n
    \n
    \n如果有root权限，可以直接运行install.rb，其会将sneetchalizer拷贝到/usr/bin下，将sneetchalizer.1拷贝到/usr/share/man/man1下。
    \n\n
    2、参数解释
    \n\n
    不翻译了，都挺简单明了的，如下：
    \n
    \nXML/HTML代码
    \n
    \n    General options:  
    \n      
    \n    -h or --help  
    \n        Print quick or full usage details respectively.  
    \n    -r or --recursive  
    \n        Search directory arguments recursively for files to convert.  
    \n    -d or --delete  
    \n        delete input files after successful conversion. May not be safe yet!!!  
    \n    -v or --verbose  
    \n        makes sneetchalizer more chatty.  
    \n    -s or --show-output  
    \n        shows output from conversion tool.  
    \n    -p or --pretend  
    \n        don't convert anything. sneetchalizer will go through the motions and print out the commands it would run. Useful for preview- ing a complex command line to ensure it does what you intend. You should interpret this option's output with a grain of salt. For example, if you include the '--sanitize' option, the files will not really be renamed when using --pretend, and as such the command's output will not reflect that the filenames would be changed during an actual run.  
    \n    -t or --terminate  
    \n        terminate sneetchalizer options. This is useful if you have to convert '--coolDir' or '-groovySong.mp3'. This is the only option whose order on the command line is significant.  
    \n    -D ARG or --out-directory=ARG  
    \n        write all outfiles to a directory argument. This is useful if you want to (re)encode files directly to a mounted portable device.  
    \n    --strict and --pedantic  
    \n        many errors that sneetchalizer may encounter are recoverable, such as specifying a directory as argument that contains no files to convert, or conversion failures in general. By default the script will print an error message and move on to the next file. If you use '--strict' then sneetchalizer will bail out at the first sign of trouble except for tag errors. With '--pedantic' the script will stop even on tag errors.   
    \n    --stasis  
    \n        Preserve timestamp (mtime) of original file.  
    \n    --threads [N]  
    \n        Experimental. Use threads to create concurrent jobs. This option takes an optional integer argument which represents the number of threads to launch. The default is two. Preliminary tests suggest there is little advantage (and even diminishing returns) when setting this number greater than the number of cores/CPUs you have. Due to the asychronous nature of threads the --verbose and --show-output flags will be silently disabled and most screen output is supressed.   
    \n    --sanitize  
    \n        Removes ,, ;, :, ', ", %, @, #, and ` from filenames and tags.  
    \n    -n [FORMAT] or --rename[=FORMAT]  
    \n        rename all outfiles (and temporary wavs) according to FORMAT. FORMAT is a string with special designators to be pulled from the file tags. The following options are available:  
    \n      
    \n            * %t Song title  
    \n            * %b Album title  
    \n            * %n Track number  
    \n            * %a Artist name  
    \n            * %y Year  
    \n            * %g Genre  
    \n            * %c Comment field  
    \n      
    \n        Directories may be created with this command, as in "%b/%n - %t". The default value of FORMAT is "%n %t".   
    \n      
    \n    Bitrate/Quality/Compression options:  
    \n      
    \n    -b or --bitrate  
    \n        mp3/ogg/m4a bitrate.  
    \n    -q or --quality  
    \n        mp3/ogg quality.  
    \n      
    \n    quality and bitrate are passed directly to lame or oggenc depending on mp3 or ogg output format respectively. Both tools can handle either a bitrate or quality argument, so it is important to understand what values are valid for the underlying tool in your specific use case. faac will accept a bitrate argument, but not a quality argument. These options will be silently ignored for any output formats other than mp3, ogg or m4a. Make sure you know what you are doing if you decide to use both in one run, and read each tools manpage for valid values. If these options are omitted the tools builtin defaults are used (-q3 for oggenc and -q5 for lame).  
    \n      
    \n    -c or --compression  
    \n        flac/mac compression level.  
    \n      
    \n    this option allows you to pass a compression argument to flac and mac. See 'flac --help' and/or 'mac --help' if you don't know what this means.  
    \n      
    \n    Format Options:  
    \n      
    \n    --out=format  
    \n        output format. Default is wav.  
    \n    --in=format[,format..]  
    \n        input format(s). Default is wav.  
    \n      
    \n    Valid output formats are: "aac", "aif", "aifc", "aiff", "aiffc", "ape", "au", "cdr", "cdda", "copy", "flac", "m4a", "m4b", "mpc", "mp4", "mpp", "mp3", "mp2", "ofr", "ofs", "ogg", "snd", "spx", "tta", "wav", "wv". Valid input formats are all of the above plus "wma". You can specify multiple input formats using a comma: 'mp3,m4a,wma'. Input format is only neccesary when passing directory arguments, as file arguments are handled by context (read: file extension). The "copy" output option copies files directly, bypassing decoding/encoding steps (useful in conjunction with --rename).  
    \n      
    \n    Tagging Options:  
    \n      
    \n    --tt or --title  
    \n        Set 'title' tag.  
    \n    --ta or --artist  
    \n        Set 'artist' tag.  
    \n    --tl or --album  
    \n        Set 'album' tag.  
    \n    --ty or --year  
    \n        Set 'year' tag.  
    \n    --tc or --comment  
    \n        Set 'comment' tag.  
    \n    --tg or --genre  
    \n        Set 'genre' tag.  
    \n    --tn or --trackn  
    \n        Set 'track number' tag.  
    \n      
    \n    The short and long versions are different in an important way: Using the long version will clobber any existing tags. The short version will only set the tag if the existing tag has no value. Note that these tags will be placed in _every_ outfile during the run.  
    \n      
    \n    Alternative Encoder/Decoder Options:  
    \n      
    \n    --gogo  
    \n        use gogo to encode mp3 files.  
    \n    --bladeenc  
    \n        use bladeenc to encode mp3 files.  
    \n      
    \n    The default is still 'lame'. If 'lame' is not found, the script will search for one of these two encoders regardless if these options are passed or not.  
    \n      
    \n    Special Options:  
    \n      
    \n    --in-optionhook=ARG  
    \n        add ARG to infile conversion command. Possibly dangerous!  
    \n    --out-optionhook=ARG  
    \n        add ARG to outfile conversion command. Possibly dangerous!

    3、使用示例
    \n\n
    如下简要的写几个使用的示例：
    \n
    \n使用示例：
    \n
    \n    $ sneetchalizer song.mp3  
    \n      
    \n    The most simple possible example, creates 'song.wav'.  
    \n      
    \n    $ sneetchalizer --out=ogg --in=flac -q5 /some/music/dir  
    \n      
    \n    This example converts every flac file in '/some/music/dir' to ogg format at quality 5.  
    \n      
    \n    $ sneetchalizer -d --out=mp3 --in=ogg,m4a,wma -b 160 .  
    \n      
    \n    Converts every ogg, m4a, and wma file in the current directory to a 160 kbps constant bitrate mp3 file. The original files are deleted.  
    \n      
    \n    $ sneetchalizer --out=mp3 --out-optionhook="--preset extreme" /some/wavs  
    \n      
    \n    Here we encode every wav in '/some/wavs' to mp3 format passing '--preset extreme' directly to lame.  
    \n      
    \n    $ sneetchalizer --in=ogg --out=ogg --quality=1 norvegianWood.ogg /some/more/oggs  
    \n      
    \n    Using the same --in and --out format allows us to resample/encode the file at a different bitrate or quality. Note that this will overwrite the original file so only do this on a copy, or use '-D' to write files to another directory.  
    \n      
    \n    $ sneetchalizer --in=ogg --out=m4a -D /mnt/ipod/ /some/oggs  
    \n      
    \n    Here we re-encode some ogg files to m4a format and write them to our mounted iPod.   
    \n

    在Android中使用GoogleMap非常方便，但是有些小技巧或者注意事项你必须牢记，否则调试半天你也不会找到啥线索，浪费时间不说，更让你狂抓，以下技巧都是我在实际项目中遇到的，不断更新和维护，如果你有类似技巧，欢迎分享：
    \n
    （以下技巧是基于SDK 1.0的）
    \n
    一、申请Apikey，并放在正确的位置
    \n
    这个应该都知道，但是是申请得到的key放哪里很多人不知道，可以放在
    \n
    1、XML布局文件中
    \n
    <view android:id="@+id/mv"
    \n   class="com.google.android.maps.MapView"
    \n   android:layout_width="fill_parent"
    \n   android:layout_height="fill_parent"
    \n   android:layout_weight="1" 
    \n   android:apiKey="01Yu9W3X3vbpYT3x33chPXXX7U1Z6jy8WYZXNFA" 
    \n   />
    \n
    2、java中
    \n
            mMapView = new MapView(this, "01Yu9W3X3vbpYT3x33chPxxx7U1Z6jy8WYZXNFA");
    \n
    二、记得导入uses-library 
    \n
     由于1.0版本的修改，使得map包不再是默认的了，使用的时候需要在manifest中的application节点下加入
    \n
    <uses-library android:name="com.google.android.maps" /> 
    \n
    \n
    否则，你将遇到可恶的“java.lang.NoClassDefFoundError: ”，切记！
    \n
    三、需要给予一定的权限
    \n
    因为要使用GoogleMAP的service，所以需要
    \n<uses-permission android:name="android.permission.INTERNET"></uses-permission>
    \n
    如果需要GPS等应用，还需要
    \n
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
    \n
    四、Activity需要继承自MapActivity
    \n
    类似如下代码；
    \n
    package com.iceskysl.showmap;
    \n
    \nimport com.google.android.maps.MapActivity;
    \n
    \nimport android.os.Bundle;
    \n
    \npublic class ShowMap extends MapActivity {
    \n    /** Called when the activity is first created. */
    \n    @Override
    \n    public void onCreate(Bundle savedInstanceState) {
    \n        super.onCreate(savedInstanceState);
    \n        setContentView(R.layout.main);
    \n    }
    \n
    \n    @Override
    \n    protected boolean isRouteDisplayed() {
    \n        // TODO Auto-generated method stub
    \n        return false;
    \n    }
    \n}

    \n
  • Use cloud storage for static files. --S3,I do not care it 's fine in china.
    • \n
  • Use HTTP Cache Control to tell the browser what it can cache.  --this is true,etag is great.
    • \n
  • Use Sphinx for text search.  --sometimes,you do have others chose.
    • \n
  • Use InnoDB for more crash resistant and faster writes.  --maybe it's right.
    • \n
  • Don't use textbook Rails ActiveRecord objects. Use New Relic to find exactly what is slow in your system. --yep
    • \n
  • Use memcache later so you find your database bottlenecks now. --this is very important.
    • \n
  • Use mongrel proctitle to find your slow queries. You are only as fast as your slowest queries. -maybe mongrel is not only chose,think about thin,ok?
    • \n
  • Use asynchronous job queuing to do work in parallel.  --yes,but sometimes crontab is enough.
    • \n
  • Use monitoring so you'll know when your site went down and why. --that's it,just do it.
    • \n
  • Learn by reading the source code, fixing problems, and submitting them back to the community.  --very userfull when you got some strange questions..
    • \n
  • Use new plugins. Old plugins can't be trusted. --and check chang histroy carefully.
    • \n
  • Use new information. Old information can't be trusted.  --and what's this?

    \n1.DYNAMICALLY LOADING CONFIG FILES INTO AN ALREADY RUNNING GOD
    \n
    \n
    God allows you to load or reload configurations into an already running instance. There are a few things to consider when doing this:
    \n
      \n    
    • Existng Watches with the same name``` as the incoming Watches will be overidden by the new config.
      • \n    
    • All paths must be either absolute or relative to the path from which god was started.
      • \n
    \n
    To load a config into a running god, issue the following command:
    \n
    $ sudo god load path/to/config.god
    # god load /data/www/api/config/config_thin_api.god```\n
    Config files that are loaded dynamically can contain anything that a normal config file contains, however, global options such as God.pid_file_directory``` blocks will be ignored (and produce a warning in the logs).

    \n1.DYNAMICALLY LOADING CONFIG FILES INTO AN ALREADY RUNNING GOD
    \n
    \nGod allows you to load or reload configurations into an already running instance. There are a few things to consider when doing this:
    \n
    \n    Existng Watches with the same name<span class="Apple-converted-space">&nbsp;</span>as the incoming Watches will be overidden by the new config.</li>
    \n    <li style="margin: 0px; font-size: 13px;">All paths must be either absolute or relative to the path from which god was started.</li>
    \n</ul>
    \n<p style="margin: 0px 0px 1em; font-size: 13px;">To load a config into a running god, issue the following command:</p>
    \n<pre style="border: 1px solid rgb(204, 204, 204); margin: 1em 0px; padding: 1em; font-size: 10px; line-height: 1.3; background-color: rgb(239, 239, 239);">$ sudo god load path/to/config.god<br /># god load /data/www/api/config/config_thin_api.god
    \nConfig files that are loaded dynamically can contain anything that a normal config file contains, however, global options such as God.pid_file_directory``` blocks will be ignored (and produce a warning in the logs).

    本书的撰写过程得益Google自身的很多服务，比如Google Doc，Google Group等等，在撰写的过程中，可以非常顺利、自然、流畅的协作。
    \n\n
    《Google API大全：编程·开发·实例》这本书是国内的第一本较为完整的介绍Google API的书，内容囊括了所有主要的Google API，并用大量的实例展示了Google API的应用方法。想更快的了解这些强大的API，本书无疑是个很好的枕边书。

    “Google改变了我的生活方式，Google API改变了我的工作方式，感谢Google，感谢一起编写本书的朋友们。”是我写给本书的一句话，做为一个比较活跃的技术工作者，我被Google深深的影响着。

    | count(id) |

    \n
    |  11042292 |
    \n
    +-----------+
    \n
    1 row in set (0.00 sec)
    \n
    \n
    wow，千万级的，看来够大，这个没啥用，先备份下数据文件，然后truncate掉
    \n
    mysql> truncate table  rails_logs_081023;
    \n
    ERROR 1105 (HY000): MyISAM table 'rails_logs_081023' is in use (most likely by a MERGE table). Try FLUSH TABLES.
    \n
    \n
    出错了，这边表貌似被MERGE用了，查了一下，果然是被rails_logs这个表MERGE着用了，那我直接truncate这个rails_logs试试看。
    \n
    mysql> truncate table  rails_logs;
    \n
    ERROR 1 (HY000): Can't create/write to file './iceskysl_beta_log/rails_logs.MRG' (Errcode: 17)
    \n
    \n
    呀，还是出错，文件不可写？Errcode: 17
    \n
    查下资料，原来：
    \n
    System error: 17 = File exists
    \n
    \n
    这咋回事，再查资料，原来.MRG是创建MERGE表的时候创建的，已经存在了。
    \n
    \n
    那就先把这个MERGE表干掉，再创建：
    \n
    先看下这个表是咋定义的：
    \n
    mysql>  show create table rails_logs;
    \n
    \n
    记录下SQL，接着drop掉。
    \n
    mysql> DROP  table rails_logs;
    \n
    Query OK, 0 rows affected (0.36 sec)
    \n
    \n
    再truncate我的目标表
    \n
    mysql> truncate table  rails_logs_081023;
    \n
    Query OK, 0 rows affected (4.22 sec)
    \n
    \n
    \n
    够快的，11042292条数据4S搞定，接着再创建下这个MERGE表，执行下上面记录的SQL就好了。
    \n
    \n
    最后确认下这表没啥问题：
    \n
    \n
    mysql> select count(id) from rails_logs;
    \n
    +-----------+
    \n
    | count(id) |
    \n
    +-----------+
    \n
    |         0 |
    \n
    +-----------+
    \n
    1 row in set (0.00 sec)
    \n
    \n
    OK，搞定，空间有了，天下太平了。
    \n
    \n
    附录：如何删除大表
    \n
    \n
    问题：有一个拥有1亿条数据的表，只需要保留其中的5条，其他删除，如何做？
    \n
    这就需要用truncate table来搞定了，如下：
    \n
    select 5条数据 into #临时表 from 1亿条数据的牛X表
    \n
    truncate table 1亿条数据的牛X表
    \n
    --让它牛X，不到10毫秒干掉它。
    \n
    insert 1亿条数据的牛X表 select * from #临时表
    \n
    drop table #临时表
    \n

    \nwow，千万级的，看来够大，这个没啥用，先备份下数据文件，然后truncate掉
    \nmysql> truncate table  rails_logs_081023;
    \nERROR 1105 (HY000): MyISAM table 'rails_logs_081023' is in use (most likely by a MERGE table). Try FLUSH TABLES.
    \n
    \n出错了，这边表貌似被MERGE用了，查了一下，果然是被rails_logs这个表MERGE着用了，那我直接truncate这个rails_logs试试看。
    \nmysql> truncate table  rails_logs;
    \nERROR 1 (HY000): Can't create/write to file './iceskysl_beta_log/rails_logs.MRG' (Errcode: 17)
    \n
    \n呀，还是出错，文件不可写？Errcode: 17
    \n查下资料，原来：
    \nSystem error: 17 = File exists
    \n
    \n这咋回事，再查资料，原来.MRG是创建MERGE表的时候创建的，已经存在了。
    \n
    \n那就先把这个MERGE表干掉，再创建：
    \n先看下这个表是咋定义的：
    \nmysql>  show create table rails_logs;
    \n
    \n记录下SQL，接着drop掉。
    \nmysql> DROP  table rails_logs;
    \nQuery OK, 0 rows affected (0.36 sec)
    \n
    \n再truncate我的目标表
    \nmysql> truncate table  rails_logs_081023;
    \nQuery OK, 0 rows affected (4.22 sec)
    \n
    \n
    \n够快的，11042292条数据4S搞定，接着再创建下这个MERGE表，执行下上面记录的SQL就好了。
    \n
    \n最后确认下这表没啥问题：
    \n
    \nmysql> select count(id) from rails_logs;
    \n+-----------+
    \n| count(id) |
    \n+-----------+
    \n|         0 |
    \n+-----------+
    \n1 row in set (0.00 sec)
    \n
    \nOK，搞定，空间有了，天下太平了。
    \n
    \n附录：如何删除大表
    \n
    \n问题：有一个拥有1亿条数据的表，只需要保留其中的5条，其他删除，如何做？
    \n这就需要用truncate table来搞定了，如下：
    \nselect 5条数据 into #临时表 from 1亿条数据的牛X表
    \ntruncate table 1亿条数据的牛X表
    \n--让它牛X，不到10毫秒干掉它。
    \ninsert 1亿条数据的牛X表 select * from #临时表
    \ndrop table #临时表

    Swap space in Linux is used when the amount of physical memory (RAM) is full. If the system needs more memory resources and the RAM is full, inactive pages in memory are moved to the swap space. While swap space can help machines with a small amount of RAM, it should not be considered a replacement for more RAM.

    Swap space can be a dedicated swap partition (recommended), a swap file, or a combination of swap partitions and swap files.

    Swap should equal 2x physical RAM for up to 2 GB of physical RAM, and then an additional 1x physical RAM for any amount above 2 GB, but never less than 32 MB.

    \n\n
    This is for a large system with memory = 512M where the system runs mainly
    \n\n
    MySQL.
    \n\n
    You can copy this file to
    \n\n
    /etc/my.cnf to set global options,
    \n\n
    mysql-data-dir/my.cnf to set server-specific options (in this

    If you want to know which options a program supports, run the program
    \n\n
    with the "--help" option.

    The usual answer is something like “rows are being placed into a temporary table which is too big to fit in memory, so it gets sorted on disk.” Unfortunately, this is not the same thing. First of all, this is Using temporary. Secondly, temporary tables may go to disk if they are too big, but EXPLAIN doesn’t show that. (If I interview you, I might ask you what “too big” means, or I might ask you the other reason temporary tables go to disk!)
    \n通常的解释是：选择出来的记录太多了，需要排序时内存中放不下了，所以会存储在磁盘中，并通过操作磁盘的文件的方式来排序。但是呢，这是不对的。\n\n
    The truth is, filesort is badly named. Anytime a sort can’t be performed from an index, it’s a filesort. It has nothing to do with files. Filesort should be called “sort.” It is quicksort at heart.
    \n正解是，filesort这个名字有问题，容易给人误解，在mysql中，任何不能通过index进行的sort都称之为filesort，这里的filesort和文件没有任何关系，应该称之为“sort”而不是“filesort”，它的内部实现就是快速排序。\n\n参考资料：\nWhat does Using filesort mean in MySQL?\nhttp://www.mysqlperformanceblog.com/2009/03/05/what-does-using-filesort-mean-in-mysql/\n\nHow MySQL executes ORDER BY\nhttp://s.petrunia.net/blog/?p=24", "created_at"=>2010-02-03 03:51:36 UTC, "updated_at"=>2012-06-24 15:46:47 UTC, "body_html"=>"

    \nThe usual answer is something like “rows are being placed into a temporary table which is too big to fit in memory, so it gets sorted on disk.” Unfortunately, this is not the same thing. First of all, this is Using temporary. Secondly, temporary tables may go to disk if they are too big, but EXPLAIN doesn’t show that. (If I interview you, I might ask you what “too big” means, or I might ask you the other reason temporary tables go to disk!)
    \n通常的解释是：选择出来的记录太多了，需要排序时内存中放不下了，所以会存储在磁盘中，并通过操作磁盘的文件的方式来排序。但是呢，这是不对的。
    \n\n
    The truth is, filesort is badly named. Anytime a sort can’t be performed from an index, it’s a filesort. It has nothing to do with files. Filesort should be called “sort.” It is quicksort at heart.
    \n正解是，filesort这个名字有问题，容易给人误解，在mysql中，任何不能通过index进行的sort都称之为filesort，这里的filesort和文件没有任何关系，应该称之为“sort”而不是“filesort”，它的内部实现就是快速排序。

    配置
    \n\n
    那么应该怎样来配置成我喜欢的颜色呢？下面我们就来详细说一些这些配置。
    \n\n
    ~/.bash_profile是bash shell中当前登录用户的配置文件。bash是“终端”中默认的shell。
    \n\n
    alias ls=”ls -G”是给”ls -G”起了一个别名，当执行ls时，就相当于执行了ls -G。
    \n\n
    CLICOLOR是用来设置是否进行颜色的显示。CLI是Command Line Interface的缩写。
    \nLSCOLORS是用来设置当CLICOLOR被启用后，各种文件类型的颜色。LSCOLORS的值中每两个字母为一组，分别设置某个文件类型的文字颜色和背景颜色。LSCOLORS中一共11组颜色设置，按照先后顺序，分别对以下的文件类型进行设置：
    \n\n
    directory
    \nsymbolic link
    \nsocket
    \npipe
    \nexecutable
    \nblock special
    \ncharacter special
    \nexecutable with setuid bit set
    \nexecutable with setgid bit set
    \ndirectory writable to others, with sticky bit
    \ndirectory writable to others, without sticky bit
    \nLSCOLORS中，字母代表的颜色如下：
    \n\n
    a 黑色
    \nb 红色
    \nc 绿色
    \nd 棕色
    \ne 蓝色
    \nf 洋红色
    \ng 青色
    \nh 浅灰色
    \nA 黑色粗体
    \nB 红色粗体
    \nC 绿色粗体
    \nD 棕色粗体
    \nE 蓝色粗体
    \nF 洋红色粗体
    \nG 青色粗体
    \nH 浅灰色粗体
    \nx 系统默认颜色
    \n所以，如果我们想把目录显示成红色，就可以把LSCOLORS设置为bxfxaxdxcxegedabagacad就可以了

    现就相关事宜申明如下：
    \n一、我开发的所有程序都没有侵犯到用户的隐私。\n\n在这个应用中，申请的全部权限为：\n
    <uses-permission android:name=\"android.permission.INTERNET\" />
    \n
    <uses-permission android:name=\"android.permission.ACCESS_NETWORK_STATE\" />
    \n
    <uses-permission android:name=\"android.permission.WRITE_EXTERNAL_STORAGE\" />

    <uses-permission android:name=\"android.permission.READ_PHONE_STATE\" />
    \n
    <uses-permission android:name=\"android.permission.ACCESS_COARSE_LOCATION\" />
    \n懂点Android技术的都知道，这些权限都是为了让该软件的功能，能够正常工作所必须的权限（连接网络，获取网络状态，下载壁纸时读写SD卡，设置壁纸，读取手机状态）和Admob的广告精准推送所需要的权限（位置信息，读取手机状态）。\n至于获取用户浏览历史记录、短信、语音邮件密码的这些明显侵犯用户隐私的行为，完全是子虚乌有。一方面并没要申请相关的权限；另一方面我还真不知道怎样获取这些敏感信息。另外，admob的精准广告服务中可能是会针对用户的地理位置等信息推送更准确的广告服务。\n关于这款应用能获取的设备标识号是用来区分设备的唯一性，免去用户注册的麻烦，而能给用户提供收藏图片的功能；而诸如获取手机屏幕大小是为了能够智能适配合适的图片。在这些设备信息中，请问哪一条会侵犯到用户的隐私。\n另外说我可以获取浏览历史信息，这简直就是个天大的笑话。如果懂一点程序的就会知道，要获取浏览器信息必须在程序里申请com.android.browser.permission.READ_HISTORY_BOOKMARKS权限。我的程序完全没有获取到权限，怎么能够获取到历史信息，真是笑话！！！\n\n二、Android手机的权限管理，在任何没有刷过第三方rom的手机上是很严格的。\n Android手机的权限管理，在任何没有刷过第三方rom的手机上是很严格的，在没有相关权限的情况下，要获取那些信息，是完全不可能的。就算是被刷过Rom的手机，也只有具有该ROM制作人的加密签名的程序，才能完成一些不安全的操作。\n我所需要的权限在用户安装的时候会很明确的告诉用户，下面我就给大家展示一下我应用申请的权限和另外一个著名的壁纸的应用background和一款管理短信的应用申请的权限。\n\n我的软件需要的权限：\n\"\"\n\n看看background（另外一款壁纸的应用）申请的权限：\n\"\"\n\nHandcent SMS申请的权限：\n\n\"\"\n\n短信有短信的权限，联系人有联系人的权限，我都没要申请，请问我如何获取相关的信息。\n\n三、应用主要面向外国用户，但绝对没有获取那些高敏感度的隐私信息！\n\n该应用主要面向外国用户（国内由于网络原因无法正常使用），连接服务器端能够获取到精确适配终端的图片，这是一款非常有用，也深受用户喜爱的应用。它确实拥有数量众多（几百万）的用户，但绝对没有获取那些高敏感度的隐私信息！我每天都收到很多用户的反馈邮件告诉我这个软件多么棒，给他们带来多少乐趣！\n\n四、我本人始终与业界同仁一道，希望建立诚实守信、和谐共生的Android产业生态系统。\n\n随着Android开放性操作平台手机的广泛使用，其应用软件开发市场正呈现蓬勃发展景象。对于提醒用户警惕来自手机上的威胁，我本人向来都是强烈支持的！本人一直始终与业界同仁一道，一直为共建诚实守信、和谐共生的Android产业生态系统而努力，将力量专注于用户需求和技术创新，创造更被用户喜欢的软解，并致力于推动手机应用软件产业持续健康发展。\n\n在此，本人郑重申明，该应用没有获取任何诸如“浏览历史记录，短信，语音邮件密码等”这种高敏感度的信息，并和国外的原作者取得联系，让其修正自己的言论并发布公开道歉，同时对于这种不负责任的言论和评价观点，对我及与我相关的应用进行不负责任的报道造成的影响给予补偿，我将保留追究其法律责任的权利。\n\nps：\n\n如果您有其他的疑问或者问题，欢迎你在我sina微博客（http://t.sina.com.cn/iceskysl）或者sohu微博（http://t.sohu.com/iceskysl）给我沟通！\n

    \n\n
    在看完这条消息后，我立马检查了所有代码，防止这款应用在我不知情的情况下，被他人加入恶意代码，但我一无所获。
    \n现就相关事宜申明如下：
    \n一、我开发的所有程序都没有侵犯到用户的隐私。
    \n\n
    在这个应用中，申请的全部权限为：
    \n<uses-permission android:name="android.permission.INTERNET" />
    \n<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

    \n懂点Android技术的都知道，这些权限都是为了让该软件的功能，能够正常工作所必须的权限（连接网络，获取网络状态，下载壁纸时读写SD卡，设置壁纸，读取手机状态）和Admob的广告精准推送所需要的权限（位置信息，读取手机状态）。
    \n至于获取用户浏览历史记录、短信、语音邮件密码的这些明显侵犯用户隐私的行为，完全是子虚乌有。一方面并没要申请相关的权限；另一方面我还真不知道怎样获取这些敏感信息。另外，admob的精准广告服务中可能是会针对用户的地理位置等信息推送更准确的广告服务。
    \n关于这款应用能获取的设备标识号是用来区分设备的唯一性，免去用户注册的麻烦，而能给用户提供收藏图片的功能；而诸如获取手机屏幕大小是为了能够智能适配合适的图片。在这些设备信息中，请问哪一条会侵犯到用户的隐私。
    \n另外说我可以获取浏览历史信息，这简直就是个天大的笑话。如果懂一点程序的就会知道，要获取浏览器信息必须在程序里申请com.android.browser.permission.READ_HISTORY_BOOKMARKS权限。我的程序完全没有获取到权限，怎么能够获取到历史信息，真是笑话！！！
    \n\n
    二、Android手机的权限管理，在任何没有刷过第三方rom的手机上是很严格的。
    \n Android手机的权限管理，在任何没有刷过第三方rom的手机上是很严格的，在没有相关权限的情况下，要获取那些信息，是完全不可能的。就算是被刷过Rom的手机，也只有具有该ROM制作人的加密签名的程序，才能完成一些不安全的操作。
    \n我所需要的权限在用户安装的时候会很明确的告诉用户，下面我就给大家展示一下我应用申请的权限和另外一个著名的壁纸的应用background和一款管理短信的应用申请的权限。
    \n\n
    我的软件需要的权限：
    \n\n
    看看background（另外一款壁纸的应用）申请的权限：
    \n\n
    Handcent SMS申请的权限：
    \n\n\n
    短信有短信的权限，联系人有联系人的权限，我都没要申请，请问我如何获取相关的信息。
    \n\n
    三、应用主要面向外国用户，但绝对没有获取那些高敏感度的隐私信息！
    \n\n
    该应用主要面向外国用户（国内由于网络原因无法正常使用），连接服务器端能够获取到精确适配终端的图片，这是一款非常有用，也深受用户喜爱的应用。它确实拥有数量众多（几百万）的用户，但绝对没有获取那些高敏感度的隐私信息！我每天都收到很多用户的反馈邮件告诉我这个软件多么棒，给他们带来多少乐趣！
    \n\n
    四、我本人始终与业界同仁一道，希望建立诚实守信、和谐共生的Android产业生态系统。
    \n\n
    随着Android开放性操作平台手机的广泛使用，其应用软件开发市场正呈现蓬勃发展景象。对于提醒用户警惕来自手机上的威胁，我本人向来都是强烈支持的！本人一直始终与业界同仁一道，一直为共建诚实守信、和谐共生的Android产业生态系统而努力，将力量专注于用户需求和技术创新，创造更被用户喜欢的软解，并致力于推动手机应用软件产业持续健康发展。
    \n\n
    在此，本人郑重申明，该应用没有获取任何诸如“浏览历史记录，短信，语音邮件密码等”这种高敏感度的信息，并和国外的原作者取得联系，让其修正自己的言论并发布公开道歉，同时对于这种不负责任的言论和评价观点，对我及与我相关的应用进行不负责任的报道造成的影响给予补偿，我将保留追究其法律责任的权利。

    \nupdate：
    \n写完申明后，去看消息出处看到其竟然做了修改，我早料到其会做相关的行为，所有早些时候截了屏幕如下：
    \n\n\n
    而现在的文章被修改为：
    \n\n\n
    看我用鼠标标识的地方，对关键信息进行了修改，感兴趣的人可以去 http://mobile.venturebeat.com/2010/07/28/android-wallpaper-app-that-steals-your-data-was-downloaded-by-millions/ 查看原文，对于这种标题党用子虚乌有的事情炒作，等消息传播后再修改自己的内容算什么行为！而对国内部分媒体在传播时不但不对真实性进行验证，还添油加醋，歪曲意思的报道，我非常无奈（看到有人还说可以获取信用卡信息，还加密传输，我实在无语）。
    \n\n
    按照我个人的感觉，他们应该紧接着要开始拿这个事件来炒作自己的产品了，我个人懒得去关注，如果有人发现有人借此炒作自己的产品，请帮忙分析分析，看看到底是什么人用这样手法。
    \n\n
    再次update！！！
    \n\n
    通过email和mylookout的人取得联系，说明我取得诸如设备号，手机屏幕大小是为了更智能的给设备适配图片，而获取部分的sim卡号是后来用户反馈说自己换了手机还想使用之前的收藏记录才使用的，这些信息只在该应用中使用，并没提供给任何第三方！
    \n\n
    同时让其确认venturebeat上文章中说到的获取浏览器历史，短信息，密码等高敏感性信息是否是他们说的还是写文章的人自己写的（Lots of my users send me the email ask me why I collect their text message and voicemail passward, I just want to make sure whether you and your ceo said that  I collected browsing history,text message ,voicemail passward during the meeting.）。
    \n\n
    其cto给我回复说他们没有说过我的应用获取过诸如text messages or browsing history这些信息（ We never stated that the wallpaper applications gathered users text messages or browsing history.），是媒体在撰写和传播的时候错误报道了（A member of the press misreported our research and he has since corrected it. ）。

    1. google就前段时间将应用暂停和我一起分析了这个应用，今天发来调查的结果：
    \n\n
    Our investigation has concluded that there's no obvious malicious code in your apps, though the implementation accesses data that it doesn't need to.  We've restored your apps (and they'll be available on Market again once you publish them), and are looking forward to seeing them updated to use ANDROID_ID.  We are likely to make a statement about this issue this week--I'll let you know.
    \n\n
    我早就说过，我配合调查，我把代码提供给他们，google也做出了公正的评判，另外也给我提了一些建议（ANDROID_ID）。
    \n\n
    2. 当时写这篇报道的venturebeat记者Dean Takahashi发来了mail，为自己犯的错误道歉，并道歉该事带来的恶劣影响，会再写一篇文章澄清这个事情以消除影响。

I'm not an expert here, but I've put together some notes on how to start working on a Rails application whilst being test-driven all the time.As an example I will use a word-learning web application. The simplest use case is to display a random word object (with its polish translation) from the database.Every time we refresh we want to see a different word.1. Create a new Rails applicationsrails my_appcd my_appRun tests with 'rake test'. It fails due to missing database configuration.2. Set up the databases - config/database.ymlThe code below assumes sqlite3 databases. development:   adapter: sqlite3   database: db/my_app_development.sqlite test:   adapter: sqlite3   database: db/my_app_test.sqlite'rake test' now runs fine.3. Create a Word class with a corresponding unit testscript/generate model Word4. Write a unit test for the Word class. Edit the test/unit/word_test.rb. def test_word_is_english_and_polish   word = Word.new :eng=>'never', :pl=>'nigdy'   assert_equal 'never', word.eng   assert_equal 'nigdy', word.pl end'rake test' now fails due to missing words table.5. Edit db/migrate/001_create_words.rbWe are using a migration here in order to create a table. It's a recommended way of dealing with database changes.  def self.up    create_table :words do |t|      t.column :eng, :string      t.column :pl, :string    end        Word.new(:eng=>'yes', :pl=>'tak').save    Word.new(:eng=>'no', :pl=>'nie').save    Word.new(:eng=>'everything', :pl=>'wszystko').save  end  def self.down    drop_table :words  endThe sample words that we are adding use Word.new .. lines, will be added to the development database. It's important to distinguish the 'test' and 'development' database. The first one is only used during tests. The latter is used by default when you start the application.Apply the migration with 'rake db:migrate'.'rake test' now succeeds with the following:'1 tests, 2 assertions, 0 failures, 0 errors'6. Fixtures and test for word.random. Edit word_test again.It's not easy to test a method which behaves randomly. Let's assume that it's enough to test that if we have only two words in our database then one of them should be called at least once per 10 calls.fixtures :wordsdef test_random results = [] 10.times {results << Word.random.eng} assert results.include?("yes")endNote the 'fixtures :words' line. Edit the 'words.yml' file.yes: id: 1 pl: 'tak' eng: 'yes'no: id: 2 pl: 'nie' eng: 'no'This will be loaded to the test database before every run of tests.7. Implement the Word.random method  def self.random    all = Word.find :all    all[rand(all.size)]  endWarning: The code above could be slow for many words in a database (we retrieve all words only for selecting a random element). It's good enough for our needs.8. Generate the Words controller with a 'learn' actionscript/generate controller Words learn9. Write a test for the learn methodJust as there is a one-to-one ratio between unit tests and models, so there is between functional tests and controllers. The Controller's responsibility is to retrieve objects from the Model layer and pass them to the View. Let's test the View part first. We use the 'assigns' collection which contains all the objects passed to the View.def test_learn_passes_a_random_word  get 'learn'  assert_kind_of Word, assigns('word')end10. Make the Test Passdef learn  @word = Word.newend11. Write more tests in the words_controller_testHow can we test that controller uses the Word.random method? We don't want to duplicate the tests for the Word.random method.Mocks to the rescue! We will only test that the controller calls the Word.random method. The returned value will be faked with a prepared word.Let's install the mocha framework:gem install mochaNow we can use 'expects' and 'returns' methods.'expects' is used for setting an expectation on an object or a class. In this case we expect that the 'random' method will be called. We also set a return value by using 'returns' method. Setting a return value means faking (stubbing) the real method. The real Word.random won't be called. If an expectation isn't met the test fails.require 'mocha'def test_learn_passes_a_random_word  random_word = Word.new  Word.expects(:random).returns(random_word)  get 'learn'  assert_equal random_word, assigns('word')end'rake test' now fails. The Word.method wasn't called.12. Rewrite the implementationdef learn  @word = Word.randomend'rake test' now passes.13. Test that a word is displayed:Extend the existing test with assert_tag calls.def test_learn_passes_a_random_word  random_word = Word.new(:pl=>'czesc', :eng=>'hello')  Word.expects(:random).returns(random_word)  get 'learn'  assert_equal random_word, assigns('word')  assert_tag :tag=>'div', :child => /czesc/  assert_tag :tag=>'div', :child => /hello/end14. Implement the view - learn.rhtml  <div>    <%= word.eng %>    <%= word.pl %>  </div>15.

That said, be sure to sudo gem install hpricot --source http://code.whytheluckystiff.net -v 0.4.86 and uninstall any hpricot versions 0.5+.

    有的时候，我们可能想吧满足某个条件的记录随机的选几条出来，比如用户查看一篇文章的时候，我们想再旁边随机的列出与这个文章相关的几篇文章，我们就有如下几个方法：
    \n\n
    1.在Ruby中一次实现
    \n\n
    things = Thing.find(:all)
    \nrandom_things = []
    \n3.times do
    \nrandom_things << things[rand(things.size)]
    \nend
    \n\n
    上面这个方法是可以的，但是有个缺点，它把整个表都查询出来,再随机的取三个，缺点很明显，如果数据库表太大，效率很差（内存等消耗很大）；且可能取出两条相同的记录（尽管概率不大），第二个问题比较好修复，如下代码即可解决：
    \n\n
    things = Thing.find(:all)
    \nrandom_things = []
    \nwhile random_things.size < 3
    \nrandom_things |= things[rand(things.size)]
    \nend
    \n\n
    2.Ruby查询两次
    \n\n
    thing_ids = Thing.find(:all, :select => 'id').map(&:id)
    \nrandom_ids = []
    \nwhile random_ids.size < 3  random_things |= things[rand(things.size)] end random_things = Thing.find(:all, :conditions => ['id IN (?)', random_ids])
    \n\n
    这个方法只是先随机取出ids较，然后再取ids对应的记录，比前面说的那个有个好处就是不会消耗太多的系统资源，比起第一种方法会快很多。
    \n\n
    3.在数据库层面上做
    \n\n
    <code>random_things = Thing.find(:all, :limit => 3, :order => 'random()')</code>
    \n\n
    是不是神奇呢，我们直接把:random(如果是MySQL则需要使用 rand()) 传给Find方法就可以了，这个方法看似比较好，其实不然，其构造出来的SQL比较变形，且对于不同的数据库不能通用。且类似与order by rand() limit 1这样的语句是很畸形的。并且这个sql效率奇低！！
    \n\n
    4.使用offset进一步改进
    \n\n
    <code>Thing.find :first, :offset => rand(Thing.count)</code>
    \n\n
    上面这个方法好多了，但是只能取一条，你可以按照第一种办法构造一个取多条的，页很简单，不是么？以上四个方法，请按照自己的实际情况使用，对于不同的需求，效率是不一样的，如果你有更好的方法，欢迎留言讨论。

    以前在JavaEye的一个讨论里，有位同志说“简历嘛，大家都知道，肯定是有水分的”。于是我在另一个blog里说到，简历里唯一有意义的，就是工作经历。认真回想一下，我在看应聘者的简历时，也基本上不看基本信息、自我评价之类的，只看工作经历：做过什么项目，用过什么技术，比说什么“熟练”、“精通”要有意义得多。我的期望、我的评估、整个后续的面试过程都是围绕着工作经历来展开的。
    \n
    求职者的工作经历，这份信息对于潜在雇主有价值。但这份价值在求职者自己身上实现了多少？作为软件开发者，不妨问问自己：还有谁记得你几年前完成的那些“不可能的任务”？还有谁记得你通宵加班为项目做出的贡献？还有谁记得客户和领导曾给你的赞扬？有多少求贤若渴的潜在雇主想要知道你曾经那些了不起的成就，却无从获取这些信息？那么这份信息的价值去了哪里？我们把工作经历告诉了谁？是的，我们把工作经历写在简历里，把简历放在了招聘网站；而招聘网站把我们的简历锁起来，把我们的工作经历信息卖给潜在雇主。我们的工作经历，去给招聘网站创造价值了。
    \n
    并非所有行业都是这样的。就拿电影来说吧，除了导演和演员以外，一部好电影离不开无数的幕后英雄：灯光、音乐、武指、剪辑……不过这些幕后英雄并没有因为身处幕后而被埋没，他们的名字出现在影片的演职员表里，展现在所有观众的眼前。当大导演想要拍下一部大影片时，他立即就能想到自己喜欢哪部影片里的配乐，然后立即就能找出这个配乐的人。幕后英雄们的每一段工作经历不仅给自己带来收入，还积累成为自己的声望，为自己打开了未来的门。
    \n
    iTechTag的目标就是让软件开发者的工作经历真正成为自己的声望，让声望给我们自己创造价值。我们希望记录下自己辛勤工作的成果，并与他人分享我们的骄傲。我们希望让别人知道我们掌握什么技能、参与过什么项目、帮助过什么客户、做出过什么贡献。我们希望让自己、让同事、让朋友、让所有关注我们的人有机会了解：我们是多么优秀的软件开发者。

    The easiest and fastest way to install Ruby gems is to install them in your local directory, you will need shell access. To install your own gems use the following steps:
    \n
    \n1) Using File Manager in your cPanel make a copy of the .bashrc file in your root directory, name it .bashrc.bak.
    \n2) Now edit the .bashrc file and add the following to the end of the file:

    lunix代码
    \n
      \n    
    1. export PATH="$PATH:$HOME/packages/bin:$HOME/.gems/bin"  
      2. \n    
    2. export GEM_HOME="$HOME/.gems"  
      3. \n    
    3. export GEM_PATH="$GEM_HOME:/usr/lib/ruby/gems/1.8"  
      4. \n

      5. \n    
    5. export GEM_CACHE=”$GEM_HOME/cache”  
      \n    
      6. \n
    \n
    \n
    3) Using your favorite SSH client connect to your site.
    \n
    \n4) at the prompt type:
    \n
    \ncp /usr/lib/ruby/gems/1.8/cache/sources-0.0.1.gem ./
    \ngem install sources-0.0.1.gem
    \ngem update -y
    \n
    \nThis will update rails to the latest version and install it to your local gem directory.
    \n
    \n5) When using a rails application, make sure you add the following to your ./config/environment.rb:
    \n
    \nENV['GEM_PATH'] = '/path/to/your/home/.gems:/usr/lib/ruby/gems/1.8'

    另外：还可以把在本地安装好gem后把其copy到Vendor目录下，但是这个方法我不喜欢，不晓得能不能直接把gem包copy到Vendor目录下？试过的告诉下下，多谢！

    注：在下面做的介绍都是以Weblogic8.1为例的，其它版本的Weblogic可能会有些许不同。
    \n
    \n1) 设置JAVA参数；
    \na) 编辑Weblogic Server启动脚本文件；
    \nBEA_HOME\\user_projects\\domains\\domain-name\\startWebLogic.cmd(startWebLogic.sh on Unix)  
    \nBEA_HOME\\user_projects\\domains\\domain-name\\startManagedWebLogic.cmd(startManagedWebLogic.sh on Unix) --这个是做集群的时候用的
    \nb) 编辑set JAVA_OPTIONS命令，如：set JAVA_OPTIONS=-Xms256m –Xmx256m；
    \n（在UNIX下把MEM_ARGS="-Xms1024m -Xmx1024m -Xmn128m"加到上述两个.sh文件中即可）
    \nc) 保存，重启即可。
    \n注：在WebLogic中，为了获得更好的性能，BEA公司推荐最小Java堆等于最大Java堆。
    \n（这个偶们的设置都是1024M的，反正偶们内存大大的4G呢）
    \n
    \n2) 开发模式 vs. 产品模式；
    \n开发模式和产品模式的一些参数的默认值不同，可能会对性能造成影响，下面是对性能有影响的参数列表：
    \n
    \n\n    \n        \n            \n            \n            \n        \n        \n            \n            \n            \n        \n        \n            \n            \n            \n        \n    \n
    参数开发模式默认值产品模式默认值
    Execute Queue: Thread Count15 threads25 threads
    JDBC Connection Pool: MaxCapacity15 connnections25 connections
    \n
    \n通过启动管理控制台，在域（如：mydomain）> 配置 > 常规选择产品模式。
    \n（这个在创建weblogic的domain的时候是有选择的，选择“产品”模式就可以了，如果后期需要修改，可以按照上面的方法修改）
    \n
    \n3) 尽量开启本地I/O；
    \n通过启动管理控制台，在域（如：mydomain）> 服务器 > server实例（如：myserver）> 配置 > 调整选择启用本地I/O。
    \n注：此值也可通过手动的修改config.xml配置文件。
    \n（这个没有试验过，不晓得有什么效果和好处，知道的告诉偶下下。）
    \n
    \n4) 调优执行队列线程；
    \na) 修改默认执行线程数
    \n在这里，执行队列的线程数表示执行队列能够同时执行的操作的数量。但此值不是设的越大越好，应该恰到好处的去设置它，太小了，执行队列中将会积累很多待处理的任务，太大了，则会消耗大量的系统资源从而影响整体的性能。在产品模式下默认为25个执行线程。
    \n（点：一般来说，其上限是每个CPU对应50个线程，其按照CPU个数线性增长.）
    \n
    \n为了设置理想的执行队列的线程数，我们可以启动管理控制台，在域（如：mydomain）> 服务器 > server实例（如：myserver）> 监视 > 性能中监控最大负载时执行队列的吞吐量和队列中的等待请求数，据此确定理想的数值。
    \n理想的默认执行线程数是由多方面的因素决定的，比如机器CPU性能、总体体系架构、I/O、操作系统的进程调度机制、JVM的线程调度机制。随着CPU个数的增加，WebLogic可以近乎线性地提高线程数。线程数越多，花费在线程切换的时间也就越多；线程数越小，CPU可能无法得到充分的利用。为获取一个理想的线程数，需要经过反复的测试。在测试中，可以以25*CPU个数为基准进行调整。当空闲线程较少，CPU利用率较低时，可以适当增加线程数的大小（每五个递增）。对于PC Server和Windows 2000，则最好每个CPU小于50个线程，以CPU利用率为90%左右为最佳。
    \n通过启动管理控制台，在域（如：mydomain）> 服务器 > server实例（如：myserver）> Execute Queue > weblogic.kernel.Defalt > 配置中修改线程计数。
    \n
    \nb) 设定执行队列的溢出条件；
    \n    Weblogic Server提供给默认的执行队列或用户自定义的执行队列自定义溢出条件的功能，当满足此溢出条件时，服务器改变其状态为“警告”状态，并且额外的再分配一些线程去处理在队列中的请求，而达到降低队列长度的目的。
    \n    通过启动管理控制台，在域（如：mydomain）> 服务器 > server实例（如：myserver）> Execute Queue > weblogic.kernel.Defalt > 配置下面几项：
    \n●队列长度：此值表示执行队列中可容纳的最大请求数，默认值是65536，最后不要手动改变此值。
    \n●队列长度阈值百分比：此值表示溢出条件，在此服务器指出队列溢出之前可以达到的队列长度大小的百分比。
    \n●线程数增加：当检测到溢出条件时，将增加到执行队列中的线程数量。如果CPU和内存不是足够的高，尽量不要改变默认值“0”。因为Weblogic一旦增加后不会自动缩减，虽然最终可能确实起到了降低请求的作用，但在将来的运行中将影响程序的性能。
    \n●最大线程数：为了防止创建过多的线程数量，可以通过设定最大的线程数进行控制。
    \n在实际的应用场景中，应根据具体情况适当的调整以上参数。
    \n
    \nc) 设定执行队列监测行为
    \nWeblogic Server能够自动监测到当一个执行线程变为“阻塞”。变为“阻塞”状态的执行线程将无法完成当前的工作，也无法再执行新请求。如果执行队列中的所有执行线程都变为“阻塞”状态，Weblogic server可能改变状态为“警告”或“严重”状态。如果Weblogic server变为“严重”状态，可以通过Node Manager来自动关闭此服务器并重新启动它。具体请参考：Node Manager Capabilities文档。
    \n通过启动管理控制台，在域（如：mydomain）> 服务器 > server实例（如：myserver）>配置 > 调整下可配置下面几项：
    \n●阻塞线程最长时间：在此服务器将线程诊断为阻塞线程之前，线程必须连续工作的时间长度(秒)。默认情况下，WebLogic Server 认为线程在连续工作 600 秒后成为阻塞线程。
    \n●阻塞线程计时器间隔：WebLogic Server 定期扫描线程以查看它们是否已经连续工作了 "阻塞线程最长时间" 字段中指定的时间长度的间隔时间(秒)。默认情况下，WebLogic Server 将此时间间隔设置为 600 秒。
    \n
    \n5) 调优TCP连接缓存数；
    \nWebLogic Server用Accept Backlog参数规定服务器向操作系统请求的队列大小，默认值为50。当系统重载负荷时,这个值可能过小,日志中报Connection Refused,导致有效连接请求遭到拒绝,此时可以提高Accept Backlog 25%直到连接拒绝错误消失。对于Portal类型的应用,默认值往往是不够的。
    \nLogin Timeout和SSL Login Timeout参数表示普通连接和SSL连接的超时时间,如果客户连接被服务器中断或者SSL容量大,可以尝试增加该值。
    \n通过启动管理控制台，在域（如：mydomain）> 服务器 > server实例（如：myserver）>配置 > 调整下可配置“接受预备连接”。
    \n
    \n6) 改变Java编译器；
    \n标准的Java编译器是javac，但编译JSP servlets速度太慢，为了提高编译速度，可以使用sj或jikes编译器取代javac编译器。下面说说更改Java编译器：
    \n通过启动管理控制台，在域（如：mydomain）> 服务器 > server实例（如：myserver）>配置 > 常规下改变Java 编译器，默认为javac。输入完整路径，如：c:\\visualcafe31\\bin\\sj.exe。然后打开高级选项，在预规划到类路径填写编译 Java 代码时为 Java 编译器类路径预规划的选项，如：BEA_HOME\\jdk141_02\\jre\\lib\\rt.jar。
    \n
    \n7) 使用Webogic Server集群提高性能；
    \n具体关于如何配置Weblogic集群，我就不细说了。详情可参考：Introduction to WebLogic Server Clustering。
    \n
    \n8) Weblogic EJB调优
    \n由于EJB2.0已经很少项目在用了，EJB3.0再成熟一点，我再补充这一部分吧！
    \n
    \n9) JDBC应用调优
    \nJDBC Connection Pool的调优受制于WebLogic Server线程数的设置和数据库进程数,游标的大小。通常我们在一个线程中使用一个连接,所以连接数并不是越多越好,为避免两边的资源消耗，建议设置连接池的最大值等于或者略小于线程数。同时为了减少新建连接的开销,将最小值和最大值设为一致。
    \n增加Statement Cache Size对于大量使用PreparedStatement对象的应用程序很有帮助,WebLogic能够为每一个连接缓存这些对象,此值默认为10。在保证数据库游标大小足够的前提下,可以根据需要提高Statement Cache Size。比如当你设置连接数为25,Cache Size为10时,数据库可能需要打开25*10=250个游标。不幸的是,当遇到与PreparedStatement Cache有关的应用程序错误时,你需要将Cache Size设置为0。
    \n尽管JDBC Connection Pool提供了很多高级参数,在开发模式下比较有用,但大部分在生产环境下不需调整。这里建议最好不要设置测试表, 同时Test Reserved Connections和Test Released Connections也无需勾上。 当然如果你的数据库不稳定,时断时续,你就可能需要上述的参数打开。
    \n最后提一下驱动程序类型的选择,以Oracle为例,Oracle提供thin驱动和oci驱动,从性能上来讲,oci驱动强于thin驱动,特别是大数据量的操作。但在简单的数据库操作中,性能相差不大,随着thin驱动的不断改进,这一弱势将得到弥补。而thin驱动的移植性明显强于oci驱动。所以在通常情况下建议使用thin驱动。而最新驱动器由于WebLogic server/bin目录下的类包可能不是最新的,请以Oracle网站为准: http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/htdocs/jdbc9201.html。
    \n
    \n10) JSP调优
    \n设置jsp-param pageCheckSeconds=-1；
    \n设置serlet-reload-check=-1或ServletReloadCheckSecs=-1；
    \n设置jsp-param precompile=true，关闭JSP预编译选项。

    \n1) 设置JAVA参数；
    \na) 编辑Weblogic Server启动脚本文件；
    \nBEA_HOME\\user_projects\\domains\\domain-name\\startWebLogic.cmd(startWebLogic.sh on Unix)  
    \nBEA_HOME\\user_projects\\domains\\domain-name\\startManagedWebLogic.cmd(startManagedWebLogic.sh on Unix) --这个是做集群的时候用的
    \nb) 编辑set JAVA_OPTIONS命令，如：set JAVA_OPTIONS=-Xms256m –Xmx256m；
    \n（在UNIX下把MEM_ARGS="-Xms1024m -Xmx1024m -Xmn128m"加到上述两个.sh文件中即可）
    \nc) 保存，重启即可。
    \n注：在WebLogic中，为了获得更好的性能，BEA公司推荐最小Java堆等于最大Java堆。
    \n（这个偶们的设置都是1024M的，反正偶们内存大大的4G呢）
    \n
    \n2) 开发模式 vs. 产品模式；
    \n开发模式和产品模式的一些参数的默认值不同，可能会对性能造成影响，下面是对性能有影响的参数列表：
    \n
    \n
    \n    
    \n        
    \n            参数
    \n            开发模式默认值
    \n            产品模式默认值
    \n        
    \n        
    \n            Execute Queue: Thread Count
    \n            15 threads
    \n            25 threads
    \n        
    \n        
    \n            JDBC Connection Pool: MaxCapacity
    \n            15 connnections
    \n            25 connections
    \n        
    \n    
    \n
    \n
    \n通过启动管理控制台，在域（如：mydomain）> 配置 > 常规选择产品模式。
    \n（这个在创建weblogic的domain的时候是有选择的，选择“产品”模式就可以了，如果后期需要修改，可以按照上面的方法修改）
    \n
    \n3) 尽量开启本地I/O；
    \n通过启动管理控制台，在域（如：mydomain）> 服务器 > server实例（如：myserver）> 配置 > 调整选择启用本地I/O。
    \n注：此值也可通过手动的修改config.xml配置文件。
    \n（这个没有试验过，不晓得有什么效果和好处，知道的告诉偶下下。）
    \n
    \n4) 调优执行队列线程；
    \na) 修改默认执行线程数
    \n在这里，执行队列的线程数表示执行队列能够同时执行的操作的数量。但此值不是设的越大越好，应该恰到好处的去设置它，太小了，执行队列中将会积累很多待处理的任务，太大了，则会消耗大量的系统资源从而影响整体的性能。在产品模式下默认为25个执行线程。
    \n（点：一般来说，其上限是每个CPU对应50个线程，其按照CPU个数线性增长.）
    \n
    \n为了设置理想的执行队列的线程数，我们可以启动管理控制台，在域（如：mydomain）> 服务器 > server实例（如：myserver）> 监视 > 性能中监控最大负载时执行队列的吞吐量和队列中的等待请求数，据此确定理想的数值。
    \n理想的默认执行线程数是由多方面的因素决定的，比如机器CPU性能、总体体系架构、I/O、操作系统的进程调度机制、JVM的线程调度机制。随着CPU个数的增加，WebLogic可以近乎线性地提高线程数。线程数越多，花费在线程切换的时间也就越多；线程数越小，CPU可能无法得到充分的利用。为获取一个理想的线程数，需要经过反复的测试。在测试中，可以以25*CPU个数为基准进行调整。当空闲线程较少，CPU利用率较低时，可以适当增加线程数的大小（每五个递增）。对于PC Server和Windows 2000，则最好每个CPU小于50个线程，以CPU利用率为90%左右为最佳。
    \n通过启动管理控制台，在域（如：mydomain）> 服务器 > server实例（如：myserver）> Execute Queue > weblogic.kernel.Defalt > 配置中修改线程计数。
    \n
    \nb) 设定执行队列的溢出条件；
    \n    Weblogic Server提供给默认的执行队列或用户自定义的执行队列自定义溢出条件的功能，当满足此溢出条件时，服务器改变其状态为“警告”状态，并且额外的再分配一些线程去处理在队列中的请求，而达到降低队列长度的目的。
    \n    通过启动管理控制台，在域（如：mydomain）> 服务器 > server实例（如：myserver）> Execute Queue > weblogic.kernel.Defalt > 配置下面几项：
    \n●队列长度：此值表示执行队列中可容纳的最大请求数，默认值是65536，最后不要手动改变此值。
    \n●队列长度阈值百分比：此值表示溢出条件，在此服务器指出队列溢出之前可以达到的队列长度大小的百分比。
    \n●线程数增加：当检测到溢出条件时，将增加到执行队列中的线程数量。如果CPU和内存不是足够的高，尽量不要改变默认值“0”。因为Weblogic一旦增加后不会自动缩减，虽然最终可能确实起到了降低请求的作用，但在将来的运行中将影响程序的性能。
    \n●最大线程数：为了防止创建过多的线程数量，可以通过设定最大的线程数进行控制。
    \n在实际的应用场景中，应根据具体情况适当的调整以上参数。
    \n
    \nc) 设定执行队列监测行为
    \nWeblogic Server能够自动监测到当一个执行线程变为“阻塞”。变为“阻塞”状态的执行线程将无法完成当前的工作，也无法再执行新请求。如果执行队列中的所有执行线程都变为“阻塞”状态，Weblogic server可能改变状态为“警告”或“严重”状态。如果Weblogic server变为“严重”状态，可以通过Node Manager来自动关闭此服务器并重新启动它。具体请参考：Node Manager Capabilities文档。
    \n通过启动管理控制台，在域（如：mydomain）> 服务器 > server实例（如：myserver）>配置 > 调整下可配置下面几项：
    \n●阻塞线程最长时间：在此服务器将线程诊断为阻塞线程之前，线程必须连续工作的时间长度(秒)。默认情况下，WebLogic Server 认为线程在连续工作 600 秒后成为阻塞线程。
    \n●阻塞线程计时器间隔：WebLogic Server 定期扫描线程以查看它们是否已经连续工作了 "阻塞线程最长时间" 字段中指定的时间长度的间隔时间(秒)。默认情况下，WebLogic Server 将此时间间隔设置为 600 秒。
    \n
    \n5) 调优TCP连接缓存数；
    \nWebLogic Server用Accept Backlog参数规定服务器向操作系统请求的队列大小，默认值为50。当系统重载负荷时,这个值可能过小,日志中报Connection Refused,导致有效连接请求遭到拒绝,此时可以提高Accept Backlog 25%直到连接拒绝错误消失。对于Portal类型的应用,默认值往往是不够的。
    \nLogin Timeout和SSL Login Timeout参数表示普通连接和SSL连接的超时时间,如果客户连接被服务器中断或者SSL容量大,可以尝试增加该值。
    \n通过启动管理控制台，在域（如：mydomain）> 服务器 > server实例（如：myserver）>配置 > 调整下可配置“接受预备连接”。
    \n
    \n6) 改变Java编译器；
    \n标准的Java编译器是javac，但编译JSP servlets速度太慢，为了提高编译速度，可以使用sj或jikes编译器取代javac编译器。下面说说更改Java编译器：
    \n通过启动管理控制台，在域（如：mydomain）> 服务器 > server实例（如：myserver）>配置 > 常规下改变Java 编译器，默认为javac。输入完整路径，如：c:\\visualcafe31\\bin\\sj.exe。然后打开高级选项，在预规划到类路径填写编译 Java 代码时为 Java 编译器类路径预规划的选项，如：BEA_HOME\\jdk141_02\\jre\\lib\\rt.jar。
    \n
    \n7) 使用Webogic Server集群提高性能；
    \n具体关于如何配置Weblogic集群，我就不细说了。详情可参考：Introduction to WebLogic Server Clustering。
    \n
    \n8) Weblogic EJB调优
    \n由于EJB2.0已经很少项目在用了，EJB3.0再成熟一点，我再补充这一部分吧！
    \n
    \n9) JDBC应用调优
    \nJDBC Connection Pool的调优受制于WebLogic Server线程数的设置和数据库进程数,游标的大小。通常我们在一个线程中使用一个连接,所以连接数并不是越多越好,为避免两边的资源消耗，建议设置连接池的最大值等于或者略小于线程数。同时为了减少新建连接的开销,将最小值和最大值设为一致。
    \n增加Statement Cache Size对于大量使用PreparedStatement对象的应用程序很有帮助,WebLogic能够为每一个连接缓存这些对象,此值默认为10。在保证数据库游标大小足够的前提下,可以根据需要提高Statement Cache Size。比如当你设置连接数为25,Cache Size为10时,数据库可能需要打开25*10=250个游标。不幸的是,当遇到与PreparedStatement Cache有关的应用程序错误时,你需要将Cache Size设置为0。
    \n尽管JDBC Connection Pool提供了很多高级参数,在开发模式下比较有用,但大部分在生产环境下不需调整。这里建议最好不要设置测试表, 同时Test Reserved Connections和Test Released Connections也无需勾上。 当然如果你的数据库不稳定,时断时续,你就可能需要上述的参数打开。
    \n最后提一下驱动程序类型的选择,以Oracle为例,Oracle提供thin驱动和oci驱动,从性能上来讲,oci驱动强于thin驱动,特别是大数据量的操作。但在简单的数据库操作中,性能相差不大,随着thin驱动的不断改进,这一弱势将得到弥补。而thin驱动的移植性明显强于oci驱动。所以在通常情况下建议使用thin驱动。而最新驱动器由于WebLogic server/bin目录下的类包可能不是最新的,请以Oracle网站为准: http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/htdocs/jdbc9201.html。
    \n
    \n10) JSP调优
    \n设置jsp-param pageCheckSeconds=-1；
    \n设置serlet-reload-check=-1或ServletReloadCheckSecs=-1；
    \n设置jsp-param precompile=true，关闭JSP预编译选项。

    透明同学说需要给技能云一个”自动登录“的功能，于是下午睡觉起来google了些资料，也大概问了下几个朋友，思路就有了，思路很多种，这里采取的是这篇文章介绍的方式。
    \n
    基本步骤如下：
    \n
    1、首先创建一个用来保存用户信息的表modle（PersistentLogin），代码如下：
    \n
    \n
    Ruby代码
    \n
      \n    
    1. class CreatePersistentLogins < ActiveRecord::Migration  
      2. \n    
    2.   def self.up  
      3. \n    
    3.     
      4. \n    
    4.     create_table :persistent_logins do |t|  
      5. \n    
    5.       t.column :uid, :string, :null => false  
      6. \n    
    6.       t.column :user_id, :integer, :null => false  
      7. \n    
    7.       t.column :created_on, :datetime, :null => false  
      8. \n    
    8.     end  
      9. \n    
    9.           
      10. \n    
    10.     add_index :persistent_logins, :uid, :name => "uid"  
      11. \n    
    11.     add_index :persistent_logins, :created_on, :name => "created_on"      
      12. \n    
    12.       
      13. \n    
    13.   end  
      14. \n    
    14.   
      15. \n    
    15.   def self.down  
      16. \n    
    16.     drop_table :persistent_logins  
      17. \n    
    17.   end  
      18. \n    
    18. end  
      19. \n
    \n
    \n
    2、然后写这个modle，代码如下：
    \n
    \n
    Ruby代码
    \n
      \n    
    1. class PersistentLogin < ActiveRecord::Base  
      2. \n

      3. \n    
    3.   belongs_to :user  
      4. \n    
    4.   before_create :assign_uid  
      5. \n    
    5.     
      6. \n    
    6.   private  
      7. \n    
    7.     
      8. \n    
    8.   def assign_uid  
      9. \n    
    9.     self.uid = UUID.random_create.to_s  
      10. \n    
    10.   end  
      11. \n    
    11. end  
      12. \n
    \n
    \n
    3、紧接着在登录的页面加一个chechk_box用来供用户选择是否保存自己的信息以实现自动登录，代码如下：
    \n
    \n
    XML/HTML代码
    \n
      \n    
    1. <%=check_box_tag("persist", value = "1", checked = true, options = {})%>    记住我吧.  
      2. \n
    \n
    \n
    4、接着在你原来的验证登录的地方，添加如下代码：
    \n
    \n
    Ruby代码
    \n
      \n    
    1. # inside your 'login' code after you have validated the credentials  
      2. \n    
    2. if params[:persist]  
      3. \n    
    3.   p = PersistentLogin.create(:user=>u)  
      4. \n    
    4.   cookies[:p_session_id] = {:value => p.uid, :expires => Time.now + 7.days}  
      5. \n    
    5. end  
      6. \n
    \n
    \n
    5、写一个前置过滤器，判断用户是否存在cookie，如下：
    \n
    \n
    Ruby代码
    \n
      \n    
    1. def get_current_user  
      2. \n    
    2.   if session[:user].nil?  
      3. \n    
    3.     if cookies[:p_session_id] && p = PersistentLogin.find_by_uid(cookies[:p_session_id])  
      4. \n    
    4.       session[:user] = c_user.id  
      5. \n    
    5.     end  
      6. \n    
    6.   end  
      7. \n    
    7. end  
      8. \n
    \n
    \n
    6、最后用户点了退出登录以后，删除cookie和表中记录，代码如下：
    \n
    \n
    Ruby代码
    \n
      \n    
    1. def logout  
      2. \n    
    2.   session[:user] = nil  
      3. \n    
    3.     
      4. \n    
    4.   if cookies[:p_session_id] && p = PersistentLogin.find_by_uid(cookies[:p_session_id])  
      5. \n    
    5.     p.destroy  
      6. \n    
    6.   end  
      7. \n    
    7.   
      8. \n    
    8.   cookies.delete :p_session_id   
      9. \n    
    9. end  
      10. \n
    \n

    透明同学说需要给技能云一个”自动登录“的功能，于是下午睡觉起来google了些资料，也大概问了下几个朋友，思路就有了，思路很多种，这里采取的是这篇文章介绍的方式。
    \n基本步骤如下：
    \n1、首先创建一个用来保存用户信息的表modle（PersistentLogin），代码如下：
    \n
    \nRuby代码
    \n
    \n    class CreatePersistentLogins < ActiveRecord::Migration  
    \n      def self.up  
    \n        
    \n        create_table :persistent_logins do |t|  
    \n          t.column :uid, :string, :null => false  
    \n          t.column :user_id, :integer, :null => false  
    \n          t.column :created_on, :datetime, :null => false  
    \n        end  
    \n              
    \n        add_index :persistent_logins, :uid, :name => "uid"  
    \n        add_index :persistent_logins, :created_on, :name => "created_on"      
    \n          
    \n      end  
    \n      
    \n      def self.down  
    \n        drop_table :persistent_logins  
    \n      end  
    \n    end  
    \n
    \n
    \n2、然后写这个modle，代码如下：
    \n
    \nRuby代码
    \n
    \n    class PersistentLogin < ActiveRecord::Base  
    \n        
    \n      belongs_to :user  
    \n      before_create :assign_uid  
    \n        
    \n      private  
    \n        
    \n      def assign_uid  
    \n        self.uid = UUID.random_create.to_s  
    \n      end  
    \n    end  
    \n
    \n
    \n3、紧接着在登录的页面加一个chechk_box用来供用户选择是否保存自己的信息以实现自动登录，代码如下：
    \n
    \nXML/HTML代码
    \n
    \n    <%=check_box_tag("persist", value = "1", checked = true, options = {})%>    记住我吧.  
    \n
    \n
    \n4、接着在你原来的验证登录的地方，添加如下代码：
    \n
    \nRuby代码
    \n
    \n    # inside your 'login' code after you have validated the credentials  
    \n    if params[:persist]  
    \n      p = PersistentLogin.create(:user=>u)  
    \n      cookies[:p_session_id] = {:value => p.uid, :expires => Time.now + 7.days}  
    \n    end  
    \n
    \n
    \n5、写一个前置过滤器，判断用户是否存在cookie，如下：
    \n
    \nRuby代码
    \n
    \n    def get_current_user  
    \n      if session[:user].nil?  
    \n        if cookies[:p_session_id] && p = PersistentLogin.find_by_uid(cookies[:p_session_id])  
    \n          session[:user] = c_user.id  
    \n        end  
    \n      end  
    \n    end  
    \n
    \n
    \n6、最后用户点了退出登录以后，删除cookie和表中记录，代码如下：
    \n
    \nRuby代码
    \n
    \n    def logout  
    \n      session[:user] = nil  
    \n        
    \n      if cookies[:p_session_id] && p = PersistentLogin.find_by_uid(cookies[:p_session_id])  
    \n        p.destroy  
    \n      end  
    \n      
    \n      cookies.delete :p_session_id   
    \n    end  
    \n

    多人协作的时候版本控制是很重要的，我以前公司使用的VSS或者CC&CQ，这些都是比较重量级的，做大项目的控制比较合适，但是做一些 rails的比较小的项目的时候就没有这个必要，也没有这个必要；
    \n
    相反，SVN和CVS可能更适合一点，因为CVS比较老，现在SVN比较主流，使用起来 也很方便，于是做Rails项目自然选择SVN，以前使用不多，虽然也会用，但是做了不少无用功，今天看到一篇介绍的文章，改吧改吧记录下。
    \n
    \n
    \n
    第一步，创建Rails应用并做基础设置
    \n
      \n    
    1. mkdir project //创建工程目录，在此目录下设置基础的导入数据  
      2. \n    
    2. cd project    //进入project目录  
      3. \n    
    3. rails test    //生成rails应用，名字为test  
      4. \n    
    4. cd test       //进入rails应用目录  
      5. \n    
    5. mv config/database.yml config/database_example.yml //修改数据库配置文件的名字，因为这个配置文件可能每个开发人员的都不一样  
      6. \n    
    6. rm -r log/*   //删除log目录下的所有文件，这个目录下的文件不需要加入到版本控制  
      7. \n    
    7. rm -r tmp/*   //同上，临时目录也不要加入版本控制  
      8. \n    
    8. cd ..         //回到project目录  
      9. \n    
    9. mv test trunk //修改rails应用test目录的名字为trunk，这是svn的惯例，相当与CVS的HEAD，是开发主目录  
      10. \n    
    10. mkdir tags    //惯例，保存tag  
      11. \n    
    11. mkdir branches//惯例，保存分支第二步，生成将项目文件导入SVN   
      12. \n
    \n
    \n没个项目的SVN库所使用的协议可能个不相同，这里假设你已经创建好了SVN库并可以使用了 。
    \n
    \n
    \n
    第二步：导入

    多人协作的时候版本控制是很重要的，我以前公司使用的VSS或者CC&CQ，这些都是比较重量级的，做大项目的控制比较合适，但是做一些 rails的比较小的项目的时候就没有这个必要，也没有这个必要；
    \n相反，SVN和CVS可能更适合一点，因为CVS比较老，现在SVN比较主流，使用起来 也很方便，于是做Rails项目自然选择SVN，以前使用不多，虽然也会用，但是做了不少无用功，今天看到一篇介绍的文章，改吧改吧记录下。
    \n
    \n
    \n第一步，创建Rails应用并做基础设置
    \n
    \n    mkdir project //创建工程目录，在此目录下设置基础的导入数据  
    \n    cd project    //进入project目录  
    \n    rails test    //生成rails应用，名字为test  
    \n    cd test       //进入rails应用目录  
    \n    mv config/database.yml config/database_example.yml //修改数据库配置文件的名字，因为这个配置文件可能每个开发人员的都不一样  
    \n    rm -r log/   //删除log目录下的所有文件，这个目录下的文件不需要加入到版本控制  
    \n    rm -r tmp/       //同上，临时目录也不要加入版本控制  
    \n    cd ..         //回到project目录  
    \n    mv test trunk //修改rails应用test目录的名字为trunk，这是svn的惯例，相当与CVS的HEAD，是开发主目录  
    \n    mkdir tags    //惯例，保存tag  
    \n    mkdir branches//惯例，保存分支第二步，生成将项目文件导入SVN   
    \n
    \n
    \n没个项目的SVN库所使用的协议可能个不相同，这里假设你已经创建好了SVN库并可以使用了 。
    \n
    \n
    \n第二步：导入
    \n
    \n    cd project 在project目录下执行  
    \n    svn import . http://your_domain/svn/test -m "初始化导入" --username your_name  
    \n
    \n
    \n如果没有错误，项目就导入成功了，现在我们到自己的rails项目工作目录checkout刚刚创建的项目
    \n
    \n
    \n
    \n第三步：签出
    \n
    \n    cd /rails //进入你的rails工作目录  
    \n    svn co http://your_domain/svn/test/trunk test //checkout代码到test  
    \n    cd test  
    \n    cp config/database_example.yml config/database.yml //创建自己的数据库配置文件  
    \n    svn propset svn:ignore database.yml config/        //忽略database.yml文件，也就是不将此文件纳入版本控制  
    \n    svn propset svn:ignore "" log/                    //忽略log下的所有文件  
    \n    svn propset svn:ignore "    " tmp/                    //忽略tmp目录下的所有文件  
    \n    svn commit -m "忽略文件"                           //提交配置好了，到现在基本的项目初始化  
    \n    
    \n

    做为一个安全爱好者，我可以负责任的告诉你，这些东西非常危险，恶意的人总是能想办法（这个办法很多，比如旁注等）拿到你的日志文件，而这个日志文件比起加密的数据库文件还要危险，于是肯定是需要做一些工作的。
    \n
    ActionController#filter_parameter_logging 就是我们需要的东西，它可以用来过滤那些你不想保存在日志中的数据，它可以阻止一些敏感数据赤裸裸的暴露在日志文件中，比如密码，或者信用卡帐号。也可以防止一些大块的数据占用日志文件，等等。
    \n如果你的应用用到passwords，复制下面这行到你的ApplicaitonController  Class:
    \n
    \n
    Ruby代码
    \n
      \n    
    1. filter_parameter_logging "password"  
      \n    
      2. \n
    \n
    \n
    这样就可以阻止任何匹配/password/i模式的数据被写入日志，诸如：[user][password] 或 [user][password_confirmation]
    \n
    \n另外，如果想在开发环境下显示POST logging,但是在产品环境下完全不显示，如何做呢？
    \n
    \n
    Ruby代码
    \n
      \n    
    1. filter_parameter_logging("password") if RAILS_ENV == "production"  
      \n    
      2. \n
    \n
    \n
    如果想完全禁止POST logging，则可以在production.rb中修改：config.log_level = :warn

    \n
    \n这样就可以阻止任何匹配/password/i模式的数据被写入日志，诸如：[user][password] 或 [user][password_confirmation]
    \n
    \n另外，如果想在开发环境下显示POST logging,但是在产品环境下完全不显示，如何做呢？
    \n
    \nRuby代码
    \n
    \n    filter_parameter_logging("password") if RAILS_ENV == "production"  
    \n    
    \n
    \n
    \n如果想完全禁止POST logging，则可以在production.rb中修改：config.log_level = :warn

    说来惭愧，写了这么久的Ruby，做了那么多的网站，也写过不少使用Rmagick来处理图片的代码，但是自己的机子上始终安装不成功，折腾了好几 次，我记得都没有最终完全搞定。本来准备使用Ubuntu上，但是很多东西在Win下使用惯了，所以还是安心的在WIN下做开发吧。

    \n

    \n
    2、先解压，然后输入命令安装：gem install rmagick-1.13.0-win32.gem
    \n
    3、然后再点ImageMagick-6.2.9-3-Q8-windows-dll.exe安装，并且把这个的安装路径放到path环境变量里面去，否则会出现CORE_RL_magick_.dll找不到的错误（需要注意，加入后CMD需要重新打开下，否则不行）。
    \n然后试试这段代码，如下：
    \n
    \n
    示例代码
    \n
      \n    
    1. require 'RMagick'

    \n### 你是：典型的“(G)激烈的电吉他”类型\n
    G类型（反叛型）音乐DNA呈显性的人，认为音乐是情绪表达的最好出口。音乐于你来讲就如同一项刺激的探险旅行，你期待在音乐中获得异于他人的新鲜体验。
    \n
      \n    
    • 速度偏爱
      • \n    
      在大多数情况下，偏爱节拍速度较快的音乐（BPM ”Beat per Minute”>80）。在歌曲节奏性与旋律性的对比上，你更倾向于节奏性较强的音乐表达和充满能量的速度感体验。
      \n    
    • 歌词偏爱
      • \n    
      简单直接，甚至带有一些无所谓何般抵抗的词汇才是脑中所想，反叛性的歌词亦是这类听者的最爱“我不愿相信真的有魔鬼,也不愿与任何人作对”，“噢姐 姐，我想回家，牵着我的手，我有些困了……”。“你会看见雾、看见云、看见太阳，纪念和大地重复着悲伤……”你完全不喜欢千篇一律的情感描述词句。
      \n    
    • 歌曲情绪体现
      • \n    
      在你看来，情绪表达是一首歌的重要内容之一。你会十分在意一首歌的情绪是否与你心情合拍，并倾向于较为直接和激烈的情绪表达。
      \n    
    • 人声体现
      • \n    
      喜欢不一样的声音，喜欢嗓子里像粘上碎玻璃的声音；喜欢人声随着乐器越来越猛烈的嘶喊，混乱、躁动，不安现状的声音会得到青睐；不喜欢做作和感情扭捏造作的口水式演唱。
      \n    
    • 曲风偏好
      • \n    
      在纷繁的音乐类型中，这种类型的爱好者会偏爱硬摇滚、另类、朋克（PUNK）、重金属Heavy metal、流行金属等能量较高的音乐。
      \n    
    • 乐器偏好
      • \n    
      偏爱电声乐器（什么是？）：如失真电吉他、电贝司、架子鼓、饱满的木吉他扫弦或是一段精彩的乐器SOLO（什么是？）中那充满延伸的电子合成器；喜欢原始却不失热情的配器，
      \n    
    • 能量消耗
      • \n    
      无论从演奏者还是演唱者，都会有极度消耗能量的倾向，而这样的倾向，会获得典型此类型人的极大共鸣
      \n    
    • 音乐人偏好
      • \n    
      Beyond、F.I.R、蔡健雅、信乐团、孙燕姿、崔健、莫文蔚、谢天啸、Metallica 、Nirvana、Korn、Green Day、Coldplay、X-Japan

    注：关于测评结果，你需要了解，
    \n
      \n    
    • YOBO 根据人们对音乐偏好的差异，将每个人的音乐DNA分为4种倾向性。你的音乐DNA可能在其中一类上尤为突出，也有可能同时倾向于2－3类不同的音乐偏好。 YOBO的前期调查显示，每个人都具有其最明显的显性倾向和相对较为隐蔽的隐性倾向，然而，没有会对4类音乐偏好都同时具有明显倾向性的人—当然，你也有 可能是最例外的一位
      • \n    
    • 在音乐心理测评报告中，我们描述你的音乐喜好所举的实例，包括歌词、歌曲、人名等等，有可能因为一些不可预计的因素而存在个体差异，请你更关注整体描述
      • \n    
    • 除了针对音乐元素的心理分析报告，我们还将分析你的性格特征和情感体现

    你是：典型的“(G)激烈的电吉他”类型
    \n\n
    G类型（反叛型）音乐DNA呈显性的人，认为音乐是情绪表达的最好出口。音乐于你来讲就如同一项刺激的探险旅行，你期待在音乐中获得异于他人的新鲜体验。
    \n
    \n    速度偏爱
    \n    在大多数情况下，偏爱节拍速度较快的音乐（BPM ”Beat per Minute”>80）。在歌曲节奏性与旋律性的对比上，你更倾向于节奏性较强的音乐表达和充满能量的速度感体验。
    \n    歌词偏爱
    \n    简单直接，甚至带有一些无所谓何般抵抗的词汇才是脑中所想，反叛性的歌词亦是这类听者的最爱“我不愿相信真的有魔鬼,也不愿与任何人作对”，“噢姐 姐，我想回家，牵着我的手，我有些困了……”。“你会看见雾、看见云、看见太阳，纪念和大地重复着悲伤……”你完全不喜欢千篇一律的情感描述词句。
    \n    歌曲情绪体现
    \n    在你看来，情绪表达是一首歌的重要内容之一。你会十分在意一首歌的情绪是否与你心情合拍，并倾向于较为直接和激烈的情绪表达。
    \n    人声体现
    \n    喜欢不一样的声音，喜欢嗓子里像粘上碎玻璃的声音；喜欢人声随着乐器越来越猛烈的嘶喊，混乱、躁动，不安现状的声音会得到青睐；不喜欢做作和感情扭捏造作的口水式演唱。
    \n    曲风偏好
    \n    在纷繁的音乐类型中，这种类型的爱好者会偏爱硬摇滚、另类、朋克（PUNK）、重金属Heavy metal、流行金属等能量较高的音乐。
    \n    乐器偏好
    \n    偏爱电声乐器（什么是？）：如失真电吉他、电贝司、架子鼓、饱满的木吉他扫弦或是一段精彩的乐器SOLO（什么是？）中那充满延伸的电子合成器；喜欢原始却不失热情的配器，
    \n    能量消耗
    \n    无论从演奏者还是演唱者，都会有极度消耗能量的倾向，而这样的倾向，会获得典型此类型人的极大共鸣
    \n    音乐人偏好
    \n    Beyond、F.I.R、蔡健雅、信乐团、孙燕姿、崔健、莫文蔚、谢天啸、Metallica 、Nirvana、Korn、Green Day、Coldplay、X-Japan
    \n

    \n
    \n
    \n注：关于测评结果，你需要了解，
    \n
    \n    YOBO 根据人们对音乐偏好的差异，将每个人的音乐DNA分为4种倾向性。你的音乐DNA可能在其中一类上尤为突出，也有可能同时倾向于2－3类不同的音乐偏好。 YOBO的前期调查显示，每个人都具有其最明显的显性倾向和相对较为隐蔽的隐性倾向，然而，没有会对4类音乐偏好都同时具有明显倾向性的人—当然，你也有 可能是最例外的一位
    \n    在音乐心理测评报告中，我们描述你的音乐喜好所举的实例，包括歌词、歌曲、人名等等，有可能因为一些不可预计的因素而存在个体差异，请你更关注整体描述
    \n    除了针对音乐元素的心理分析报告，我们还将分析你的性格特征和情感体现

    Google放出来的AJAX feed API我老早就关注到了，也试用了一些，感觉还真的不错，现在又添加了一些东西，如下：
    \n其API都很简单，详细的可以看这个页面上的介绍：
    \nhttp://code.google.com/apis/ajaxfeeds/documentation/reference.html#FeedControl
    \n只有一个构造器：FeedControl
    \n四个函数：
    \n1.addFeed(url, label) //添加需要显示的FEED的URL
    \n2.addFeed(element, opt_options?)；//这个其实就是draw方法，指定显示的方式，例如：
    \n\n

    \ndocument.getElementById("feedControl"),
    \n{
    \ndrawMode : google.feeds.FeedControl.DRAW_MODE_TABBED
    \n});
    \n\n
    feedControl这个是页面的DOM的ID名称，google.feeds.FeedControl.DRAW_MODE_TABBED 就是指定的显示方式，默认值是：google.feeds.FeedControl.DRAW_MODE_LINEAR.
    \n\n
    3.setNumEntries(num)； //设定显示的条数（貌似只能统一指定，不能为各个FEED单独指定）
    \n4.setLinkTarget(linkTarget) //设定链接的打开方式，其值分别如下：
    \n\n

    • google.feeds.LINK_TARGET_TOP - links will open in the topmost frame

    This morning we added a new class to the Google AJAX Feed API designed to allow you to more easily add a collection of feeds to your pages. The FeedControl is pretty simple:
    \n\n
    var feedControl = new google.feeds.FeedControl();
    \nfeedControl.addFeed("http://www.digg.com/rss/index.xml", "Digg");
    \nfeedControl.addFeed("http://feeds.feedburner.com/Techcrunch", "TechCrunch");
    \nfeedControl.draw(document.getElementById("feedControl"));
    \n\n
    In addition to the formal documentation, we have put together a few samples to help you quickly come up to speed.

      • \n    
    • backport array and hash query parameters
      • \n    
    • fix in place editor’s setter action with non-string fields
      • \n    
    • updated config/boot.rb to correctly recognize RAILS_GEM_VERSION
      • \n

    \nAll users of Rails 1.2.4 or earlier are advised to upgrade to 1.2.5, though it isn’t strictly necessary if you aren’t working with JSON. For more information the JSON vulnerability, see CVE-2007-3227.
    \nSummary of changes:
    \n
    \n    acts_as_list: fixed an edge case where removing an item from the list then destroying the item leads to incorrect item positioning
    \n    deprecated calling .create on has_many associations with an unsaved owner (like post = Post.new; post.comments.create)
    \n    backport array and hash query parameters
    \n    fix in place editor’s setter action with non-string fields
    \n    updated config/boot.rb to correctly recognize RAILS_GEM_VERSION
    \n
    \nTo upgrade, gem install rails, set RAILS_GEM_VERSION to ‘1.2.5’ in config/environment.rb, and rake rails:update:configs.

    在infoQ上看到一篇关于软件构架的文章，说了一个软件构架中可能存在的一些错误，有些错误在现有的软件，项目构架中是普遍存在的问题，转载记录一二。
    \n
    虽然我不是构架师，但是在做RoR项目的时候，这些角色都是混杂起来的，必须是全部了解，因为没有那么多的空闲资源，所以了解还是很有必要的。
    \n
    原文开始：
    \n
    IASA成员Eoin Woods发表了一篇文章讲述他所认为的十大软件架构错误——常常要碰得头破血流才会得到的一些教训。这十大错误简要总结如下：
    \n
      \n    
    1. 不能界定项目范围。“在这种情况发生时，一个简单的出差登记系统结果变成内建了完整的花费报销管理系统，项目费用、时间跨度和质量都留下不可避免的烂摊子……除了简单的登录真的不需要安全措施了？用户登录系统后真的不能够执行任何系统操作吗？”
      2. \n    
    2. 网撒得不够宽。“我们都曾经犯过的一个错误是，只关注系统所有利益相关者中的一两方——通常受让人（为系统出钱的人）和最终用户得到了全部的关注。”
      3. \n    
    3. 只关注功能。“……除非系统表现出了全面的高质量（诸如性能、安全、可维护性等等），否则不太可能成功。”
      4. \n    
    4. 用方框和线条来描述。“[一个无所不包的]巨大的Visio图无法成为有效的架构描述，有两个原因：第一，它试图在单一表示中呈现太多信息；第二，没人真正清楚地知道你画的各种符号到底表示什么意思。”
      5. \n    
    5. 忘了需要培养的过程。“在建造系统的时候常常需要小心的事物包括：开发者和测试者没法真正理解设计，他们不热衷或者没时间学习技术，以及还没有很好的工具支持的新技术，或者新技术会强迫人们以新的不熟悉的方式工作。”
      6. \n    
    6. 平台定义不精确。“光用‘需要Unix和Oracle’来描述你的平台是不足够的。你需要精确地说明每一部分具体的版本和配置，才能保证得到你所需的平台。不然如果有人好心为平台的某一部分升级了一个库，就可能导致某些东西停止运作。精确定义平台你才能在部署中避免这样的情形。”
      7. \n    
    7. 对性能和伸缩能力想当然。“及早开始考虑性能和伸缩性，构建性能模型尝试预测关键的性能指标并定位瓶颈，在设计逐渐成型的同时投入到一些实际的验证性工作中去。这会帮助你提高对设计中不存在严重性能和伸缩性缺陷的信心。”
      8. \n    
    8. 自己发明安全技术。“多 年来许多系统所犯的一个错误是试图加入自己发明的安全技术来提高系统安全性。比如定制的加密算法，开发者自己编写的审核系统，甚至完全DIY的访问控制系 统。自家开发的安全方案基本上都是不明智的。虽然很多人都以为自己可以马上搞出一些聪明的安全技术，但通常都只是自作聪明。”
      9. \n    
    9. 没有灾难恢复。“要想得到资源来实现系统的灾难恢复机制，其关键在于在若干真实的场景中，具体衡量系统不可用所导致的损失。如果你还能估算这些场景发生的概率，你就可以用这两组数据去说服人们灾难恢复的重要性，并获得合理的预算去实现它。”
      10. \n    
    10. 没有撤退计划。“确保无论在系统部署或升级的过程中发生任何事，你都有一份书面的、经过审查的、一致同意的撤退计划，允许你将整个环境恢复到部署之前的状态。”

    主题Web 2.0,Ruby on Rails
    \n
    编者按：因 为Ruby on Rails的出现，借用互联网创业的人越来越多，虽然不能说全是RoR的功劳，但至少说明技术门槛的降低加速了互联网的发展。从前从一个点子的产生到实现 可能要耗费少则几个月，多则几年的时间，而现在，只要你的点子够新，有实践的可能，几天几周就可以看到原型。而后面的维护也比较方便，几乎可以说是实时进 行。本文通过采访技能云网站的策划人熊节和主设计师Iceskysl就是想证明前文所述，据两人介绍，这两个到现在还没有见过面的年轻人通过网络，在不到两周的时间里，将一个创意点子变成了现实。
    \n
    InfoQ中文站：这个项目发布后，你被人问到的最多的三个问题是什么？
    \n
    InfoQ中文站：介绍一下你自己和你的团队？ 
    \n
    IceskYsl：我是IceskYsl，目前还是靠Java吃饭，ROR是暂时还是业余活动，很享受这种方 式；1sters!暂时还是个虚拟的、我自己心中理想中的团队模式，也正一步步的走向成熟。我接触RoR有一段时间了，期间被它的灵活吸引，有事没事的就 会写写代码，时间不多，写了好几个像模像样的系统如：
    \n
      \n    
    1. byeloo.cn（毕业咯）：一个开源的多班级同学录系统，趴在床上用笔画出大概的模块以及基本的数据结构后；利用一个通宵写完了整个框架，而后就上线使用，根据同学们的要求，主键完善。目前功能都很实用；
      2. \n    
    2. 然后是1stlog，一个针对国内用户的基于ROR的blog程序，功能强大可定制，方便扩展，已经发布两个版本，马上即将发布第三个版本；
      3. \n    
    3. 1sters.com：一个集新闻，产品展示，官方blog，已经产品缺陷跟踪管理于一体的CMS系统；
      4. \n    
    4. 1stimes：第一次是一个分享你我第一次经历的Web 2.0的系统；
      5. \n    
    5. itechtag：技能云。
      6. \n
    \n
    熊节：我是熊节，网名叫"透明"的。先后干过媒体、程序员、咨询师三种职业，所以有一堆Web 2.0的点子。可惜每天忙忙叨叨的，这些点子落地的很少。
    \n
    InfoQ中文站：技能云的创意是从何而来？
    \n
    IceskYsl：项目的创意随着时间逐步演化，起初只是为程序员及其相关的人提供一个展现自我的平台，为国内的程序员赢得更多的他曾被无形剥夺的东西；进而发展为项目展示、交流、经验分享及其人脉的一个平台。
    \n
    熊节：这个东西的想法很简单：我要有一个widget挂 在我的blog上，告诉别人我有些什么技能，譬如说我Ruby很不错、Java很不错、JavaScript也有经验，等等。为什么我想给别人show这 些呢？因为我觉得骄傲，为自己骄傲。我在过去的8年里一直在编程，我掌握了那么多的技能，我觉得很骄傲。说白了就是，我要向别人炫耀自己的技能。
    \n
    东西很简单，但背后可以有引申。这个炫耀的widget一展开，就引出了别的东西，那就是从哪里得到这些技能的信息。当然了，只有从项目经验里来。 只有真正在项目里做过，用过一种技术，你才能说你掌握了这种技能。而且一般来说，技能掌握的熟练程度还是和使用的时间成正比的。所以iTechTag是以 项目为基础的。你不能说自己"精通"、"熟练掌握"什么技能，你必须证明，证据就是真实的项目经验。
    \n
    那么有了一个炫耀的widget，有了一堆项目经验，就可以很方便的导出简历了。（这是我们下一步的重点功能。）技能－经验－简历，这个三位一体就 构成了一个程序员的声望（reputation）。谁对这些声望感兴趣呢？当然是正在招人的潜在雇主。换句话说iTechTag的注册用户在炫耀的同时顺 手得到了直接面对潜在雇主的机会。这就是我一开始说的，“释放程序员声望的价值”。如果说开源软件是把源代码的价值还给程序员（和用户），那么 iTechTag这个模式就像是人才招聘领域的开源，把程序员的价值还给程序员（和潜在雇主）。

    \nInfoQ中文站：这个项目的开发过程是怎么样子的，比如时间、人力等？
    \nInfoQ中文站：敏捷开发方法在你们的开发过程中有没有得到什么实践？
    \nInfoQ中文站：类似于用RoR开发技能云这样的项目，有什么经验和教训和大家分享？

    "Freezing Rails is recommended if you are using a Rails application for a business site or another production environment where stability is the most important concern (if you don't freeze your application, there is a small possibility that your application might stop working due to compatibility problems when a new version of Rails is installed on our servers)."
    \n
    方法很简单：rake rails:freeze:gems等几个命令就ok，会把rails单独拷贝到你的 vender下，而rails启动的时候先看这个目录，如果有就加载，没有的话再加载系统的。

    至于为什么这么做，你可以参考他写的文章：http://support.tigertech.net/freeze-rails

    \n按照作者给出的用法，如下：

    It can be run with 2 optional parameters: “atime”, which defines the time in minutes that will be compared against the last access time of a session file and “ctime” which defines the time in minutes that will be compared against the creation time of a session file. The default values are: ctime = 120 (minutes) and atime = 20 (miuntes) which means that the session files not accessed in the last 20 minutes and created earlier than 2 hours ago will be removed when the script runs.
    \n
    保存到你的lib/tasks目录下，然后用rake -T就可以看到这个rake命令，可以接受两个参数，举个例子，如下：
    \n
    \n
    \n
    Ruby代码
    \n
      \n    
    1. rake tmp:sessions:clear_expired atime=15 ctime=60  
      2. \n
    \n
    \n另外，还google到一段直接配置的脚本，如下：
    \n
    Here's a cron-only one liner which, every 30 min, removes all session files that haven't been accessed in 4 hours.  10,40 * * * * /usr/bin/find /u/apps/*/current/tmp/sessions -name "ruby_sess*" -amin +240 -exec rm {} \\;

    当使用了svn版本控制系统后每个目录下都会有一个.svn目录存在，开发完当交付产品或者上传到服务器时一般要把这些目录删除，这里总结了一下在linux和win下的办法。
    \n
    一、在linux下
    \n
    删除这些目录是很简单的，命令如下
    \n
    \nfind . -type d -name ".svn"|xargs rm -rf
    \n
    或者
    \n
    find . -type d -iname ".svn" -exec rm -rf {} \\;  
    \n
    全部搞定。(http://tech.techweb.com.cn/redirect.php?fid=26&tid=205673&goto=nextnewset)
    \n
     
    \n
    二、在windows下用以下法子：
    \n
    1、在项目平级的目录，执行dos命令： 
    \nxcopy project_dir project_dir_1 /s /i
    \n
     
    \n
    2、或者在项目根目录执行以下dos命令 
    \nfor /r . %%a in (.) do @if exist "%%a\\.svn" rd /s /q "%%a\\.svn"
    \n
    其实第二种方法可以用来干很多事的，比如把代码中的.svn替换为任意其他文件名并在硬盘根目录下执行，就可以从硬盘上删除所有的这个文件啦。
    \n
    3、加注册表
    \n
    Jon Galloway提供了一段注册表代码，可以将”Delete SVN Folders”命名增加到资源管理器的右键上，这样，鼠标点两下就能把选中目录下的所有.svn目录干掉了。Works just great!
    \n

    等到网站有第一批用户，为了牢牢抓住他们，及利用他们带更多用户 进来，必须更加揣摩他们的心思甚或社交习惯。结果更深化了这样的 发展，更加走向某一种文化氛围或者社会阶层，再也无法回头。

    \n
    本职工作，公司的项目我貌似完成的相当不错，开发和运维做的都不错的，电信级的产品让自己也学到了不少东西，虽然都是点点滴滴的，但每每需要用到什么东西的时候，我都可以搞定的差不多。有些机会，没有真正抓住，但是也促使了其他的一些新的机会，貌似很不错。
    \n
    课余活动，貌似真的很丰富，我能用Rails实现了很多自己以前想到却无法实现的东西，做了一批我心目中的网站，虽然没有取得巨大的成功，但是看看技能云（iTechTag）、1.s.t，以及byeloo，1stlog，第一次等等，我自己都不敢相信，这些都是我做的。构建自己理想的团队模式和氛围1sters.com，做为国内第一批专业的ROR技术团队，虽然我们不曾实际运转，但其让我积累足够的经验。
    \n
    晓得了什么是敏捷开发，什么是rails，什么是mogrel，ngnix等等等。。晓得了代码还可以这么优雅和舒服。
    \n
    继续了天马行空的梦想，虽然遇到了不少困难和挫折，但是我们挺过来了，还是有那么多的安全爱好者兄弟，浪子，小A，丰初，心雨以及其他几个朋友，让我保持了对安全领域兴趣和爱好。
    \n
    协助Tudou编辑nohack杂志，nohack中我还算是元老吧，从创办到现在，风风雨雨，虽然我不曾尽全力，但是始终关注，尽自己的一份绵薄之力，虽然还不成见过那群很神秘的TUdou、裤子，LCX等等。对nohack的热爱，使得自己也对网络安全保存自己的特有视觉。
    \n
    另外认识了一些创业界的朋友，看着朋友的网站“圈内”，“公益街”，“recity”，“善学”，“菜盘子”等等，看着他们为自己的理想工作，实在不错;接触到ROR世界中的一些活跃者，看到未来的趋势。认识了一起扯蛋、讨论的reacoo，公益街那个心怀梦想的monty，上海recity的创者，透明、infoQ的老霍（泰稳）、不曾见面却提供很多帮助的fengbo，给我很多建议cash.zhao，一起讨论问题的tails， 在我故乡的创建自己善学的jouy、来自德国的maxime、在家过着我向往的节奏生活的snowzhang，javaeye的robbin前辈，国内ROR实践的先行者dongbing、rails的布道者caiwangqin、道喜以及程序员杂志社的朋友们。
    \n
    还有伴着我已经5年风雨的shine，虽然没有多少惊喜，但是我们一起走过，琐碎的生活，让我们学会更多，虽然也曾惹你生气、流泪，但请相信，我们的未来肯定是美好的，相伴一生。
    \n
    一年时间不算太长，我忙忙碌碌的没有停歇，回首过去，点点滴滴。
    \n
    已经到来的2008,是充满希望的一年，虽然说不上雄伟的计划，但是2008中还是心怀梦想的，希望2008年，我们的’技能云‘能爆发全面的威力;希望朋友们的梦想都能成真，还有诸多暂时不能说的秘密。

    \n课余活动，貌似真的很丰富，我能用Rails实现了很多自己以前想到却无法实现的东西，做了一批我心目中的网站，虽然没有取得巨大的成功，但是看看技能云（iTechTag）、1.s.t，以及byeloo，1stlog，第一次等等，我自己都不敢相信，这些都是我做的。构建自己理想的团队模式和氛围1sters.com，做为国内第一批专业的ROR技术团队，虽然我们不曾实际运转，但其让我积累足够的经验。
    \n晓得了什么是敏捷开发，什么是rails，什么是mogrel，ngnix等等等。。晓得了代码还可以这么优雅和舒服。
    \n继续了天马行空的梦想，虽然遇到了不少困难和挫折，但是我们挺过来了，还是有那么多的安全爱好者兄弟，浪子，小A，丰初，心雨以及其他几个朋友，让我保持了对安全领域兴趣和爱好。
    \n协助Tudou编辑nohack杂志，nohack中我还算是元老吧，从创办到现在，风风雨雨，虽然我不曾尽全力，但是始终关注，尽自己的一份绵薄之力，虽然还不成见过那群很神秘的TUdou、裤子，LCX等等。对nohack的热爱，使得自己也对网络安全保存自己的特有视觉。
    \n另外认识了一些创业界的朋友，看着朋友的网站“圈内”，“公益街”，“recity”，“善学”，“菜盘子”等等，看着他们为自己的理想工作，实在不错;接触到ROR世界中的一些活跃者，看到未来的趋势。认识了一起扯蛋、讨论的reacoo，公益街那个心怀梦想的monty，上海recity的创者，透明、infoQ的老霍（泰稳）、不曾见面却提供很多帮助的fengbo，给我很多建议cash.zhao，一起讨论问题的tails， 在我故乡的创建自己善学的jouy、来自德国的maxime、在家过着我向往的节奏生活的snowzhang，javaeye的robbin前辈，国内ROR实践的先行者dongbing、rails的布道者caiwangqin、道喜以及程序员杂志社的朋友们。
    \n还有伴着我已经5年风雨的shine，虽然没有多少惊喜，但是我们一起走过，琐碎的生活，让我们学会更多，虽然也曾惹你生气、流泪，但请相信，我们的未来肯定是美好的，相伴一生。
    \n一年时间不算太长，我忙忙碌碌的没有停歇，回首过去，点点滴滴。
    \n已经到来的2008,是充满希望的一年，虽然说不上雄伟的计划，但是2008中还是心怀梦想的，希望2008年，我们的’技能云‘能爆发全面的威力;希望朋友们的梦想都能成真，还有诸多暂时不能说的秘密。
    \n期待我们完美的2008..还没有盘点的XDJM该盘点下再前行啦。。

    \n
    Fast, simple, designed to mirror the style of memcached. Rails plugin available, or usable with a simple Ruby-based API. Server written in C, but is very easy to install. Memory only…jobs are not persistent. New, so the internal protocol may change. Workers may be difficult to manage.
    \n
    bj
    \n
    Rails plugin. Self-spawning. Can only send shell commands. Jobs start a full copy of your Rails app on every execution.
    \n
    BackgroundRB
    \n
    Ruby-based. Can be polled for incremental feedback on the progress of a job. Recently rewritten.
    \n
    Amazon SQS
    \n
    Runs on Amazon’s cluster, so it can handle a ton of traffic.  Operated by Amazon, so it doesn’t run locally. Not open source.
    \n
    Apache ActiveMQ
    \n
    Well-known. Persistent. Requires several installation steps and database tables.

    ActiveMessaging

    在本地装多少gems都无所谓，但是当在服务器上或者是 share host的时候，有的时候并不是您需要的gems都有安装的，这个时候，我们在想最好是在本地把需要的gems打包到vendor里面去，这样怎么迁移都不怕了。
    \n于是google了一番，发现老外们已经实践过了，方法其实也不难，主要是要区分一些gems是无法做大的，但是其他的貌似都是可以的。
    \n具体做法请参考如下这几个文章：

    I ported the php code for open flash chart to ruby and so far it has worked quite well with Rails. Just ported the latest 1.9.6 version – see the many graph examples below. To install and use the open flash chart plugin for Rails do the following:
    \n
    \n
      \n    
    1. script/plugin install http://svn.pullmonkey.com/plugins/trunk/open_flash_chart/
      2. \n    
    2. Move the open_flash_chart.swf file into your RAILS_ROOT/public directory
      3. \n    
    3. Create a controller and a view as in my examples below.
      4. \n

    \n
    \n于是乎开始google，找到有类似问题的文章如下：

    \n错误基本上是一样的，但是这个文章没有仔细说是什么原因，只说了：
    \n
      And the problem was almost solved - problem with log rotation.  
    \nSo, if you face the same problem, try to perform few operations in your rails console... and if you are lucky, you will find the bug.
    \n
    也就是说是日志rotation的时候的问题。
    \n2、Rails Logging Tips
    \n这篇文章说了一些Rails中使用logger的技巧，没有说到这个问题，只是让我更清楚logg的机制。
    \n3、Strange logger rotation failure
    \n这个邮件列表说了基本上类似的问题，他的原因是由于配置了多个cronb，而导致的，说的比较详细。
    \n
    \n以上只是我的分析过程，而我遇到的这个问题，还有待进一步的分析和排查，有后续进展再补充。
    \n如果有遇到类似问题的朋友，还请指教一二，别让我重复造轮子，谢谢！

    最近技能云遇到一个很奇怪的问题，每天凌晨的时候，转换日志的时候都会出现一些问题，导致应用程序无法访问，每次都是重启后才能恢复，相当怪异。
    \n理了下，应该是从我使用backgroundrb任务队列以后开始的，原来是没有问题的，每天凌晨的时候会自动切换日志文件名称。
    \n而我在backgroundrb里面是定时的同步用户的Feeds用的，会调用相关的model中的方法解析RSS，入库等操作，自然这个过程中也是有日志的。

    1、升级Rails2.02的时候遇到的
    \n
    升级前，版本如下：
    \n
    iceskysl@IceskYsl:~$ gem -v
    \n0.93
    \niceskysl@IceskYsl:~$ rails -v

    前天晚上，把‘技能云’升级到Rails2.02版本后，只是大概的测试了下功能，把发现的问题予以修复，但是由于时间比肩紧急，没能全部覆盖到，昨天发现了不少遗留问题，都陆续的解决了，只有一个使用attachment_fu上传用户头像的地方还有些问题，下面是具体的分析和过程。

    错误日志
    \n
      \n    
    1. Parameters: {"commit"=>"涓婁紶..", "action"=>"upload_user_pic", "controller"=>"user", "asset"=>{"uploaded_data"=>#<ActionController::UploadedStringIO:0xb6435ee8>, "user_id"=>"1"}}

    2. Error:undefined method `callbacks_for' for #<Asset:0xb643149c>銆傘€?  
      3. \n
    \n
    \n从上面的作物日志可以看到，是调用callbacks_for的时候出的问题，而我当时使用的attachment_fu是比较老的版本，作者在后面更新过一次，于是：
    \n
    1、首先更新版本，发现依然无法使用，还是类似的错误
    \n
    2、在COR上发个帖子，大家都说自己的rmagick没有问题，奇怪的很。
    \n
    3、Google下，找到有人遇到类似问题，如下：
    \n\n
    而上面两个地址都给了另外一个页面的链接地址“Edge callback refactorings && attachment_fu" ,看来找到问题了，在其页面上说到：\n
    \n
    引用
    \n
      \n    
    1. Edge changeset 8664 introduces ActiveSupport::Callbacks.  
      2. \n    
    2. This currently breaks attachment_fu's callback internals and may affect other plugins as well ...  
      3. \n
    \n
    \n
    \n
    哦，原来是Rails中的改动影响了这个插件，\n
    \n
    改动message说明
    \n
      \n    
    1. Extract ActiveSupport::Callbacks from Active Record, test case setup and teardown, and ActionController::Dispatcher. Closes #10727.   
      2. \n
    \n
    \n
    \n
    详细的你可以参考这个页面，我就不多说了，下面主要说说怎么解决。

    按照上面给出的俄那个页面上的方法，做如下处理，将下面这段代码中的三个方法copy到attachment_fu中的attachment_fu.rb 中，覆盖其原来的callback_with_args方法。

    前天晚上，把‘技能云’升级到Rails2.02版本后，只是大概的测试了下功能，把发现的问题予以修复，但是由于时间比肩紧急，没能全部覆盖到，昨天发现了不少遗留问题，都陆续的解决了，只有一个使用attachment_fu上传用户头像的地方还有些问题，下面是具体的分析和过程。
    \n
    \n
    \n错误日志
    \n
    \n    Parameters: {"commit"=>"涓婁紶..", "action"=>"upload_user_pic", "controller"=>"user", "asset"=>{"uploaded_data"=>#<ActionController::UploadedStringIO:0xb6435ee8>, "user_id"=>"1"}}  
    \n    Error:undefined method `callbacks_for' for #<Asset:0xb643149c>銆傘€?  
    \n
    \n
    \n从上面的作物日志可以看到，是调用callbacks_for的时候出的问题，而我当时使用的attachment_fu是比较老的版本，作者在后面更新过一次，于是：
    \n1、首先更新版本，发现依然无法使用，还是类似的错误
    \n2、在COR上发个帖子，大家都说自己的rmagick没有问题，奇怪的很。
    \n3、Google下，找到有人遇到类似问题，如下：
    \n
    \n    attachment_fu: undefined method 'callbacks_for': updated
    \n    Побился attachment_fu
    \n
    \n而上面两个地址都给了另外一个页面的链接地址“Edge callback refactorings && attachment_fu" ,看来找到问题了，在其页面上说到：
    \n
    \n引用
    \n
    \n    Edge changeset 8664 introduces ActiveSupport::Callbacks.  
    \n    This currently breaks attachment_fu's callback internals and may affect other plugins as well ...  
    \n
    \n
    \n
    \n哦，原来是Rails中的改动影响了这个插件，
    \n
    \n改动message说明
    \n
    \n    Extract ActiveSupport::Callbacks from Active Record, test case setup and teardown, and ActionController::Dispatcher. Closes #10727.   
    \n
    \n
    \n
    \n详细的你可以参考这个页面，我就不多说了，下面主要说说怎么解决。
    \n按照上面给出的俄那个页面上的方法，做如下处理，将下面这段代码中的三个方法copy到attachment_fu中的attachment_fu.rb 中，覆盖其原来的callback_with_args方法。
    \n

    \n      
    \n          def callback_with_args(method, arg = self)  
    \n             notify(method)  
    \n      
    \n              result = run_callbacks(method, { :object => arg }) { |result, object| result == false }  
    \n      
    \n              if result != false && respond_to_without_attributes?(method)  
    \n                result = send(method)  
    \n              end  
    \n      
    \n              return result  
    \n          end        
    \n      
    \n          def run_callbacks(kind, options = {}, &block)  
    \n            options.reverse_merge!( :object => self )  
    \n            ::ActiveSupport::Callbacks::Callback.run(self.class.send("\#{kind}_callback_chain"), options[:object], options, &block)

    也就是，生成链接地址，但是当遇到这个字段为空的时候，就挂了，也就是上面这个错误的原因了。

    查看了下link_to 的源代码，如下：

    2. 66         case options

    \n2.5号赶上长沙会合肥的飞机，第一次坐飞机，好小的的飞机哦，呵呵，天上飞的果然比地上跑的快，1个小时10分钟就降落在合肥机场，快！
    \n在合肥找到前天晚上到合肥的哥哥，坐上比平时价格翻了三倍的汽车，2.5号下午6.30分终于到家了。
    \n家里都还挺好，新盖的房子也挺好的，希望父母能住着舒服安心，我也可以安心了。
    \n好心的同时帮我预定了2.10号合肥到深圳的机票，一大早从家里出发，赶车到合肥，走的比较快，遭到了3个小时，竟然不能提前办理登机手续，又没吃饭，可恶的机场里面一盒大饼都要25元，真是强盗。寄存了行李，坐上一块钱的公交回合肥市找东西吃，路上遇到一个超市，下车买了填肚子的东西，真便宜，再BS下机场里面卖东西的。
    \n2.10下午5点抵达深圳机场，这次飞机好大，大的有点恐怖，呵呵。。
    \n我终于回来了，尽管背了本本，无奈没有网络，只能处于离网状态，回来后，一切恢复，新年新气象，本命年的我，今年要实现哪些目标呢？
    \n嘻嘻～流水帐～～

    春节回家时，在逛街的时候，才买了4个月的手机丢了（联想i908），回来后第一件事情就是再选一款合适的手机，说实在的，选手机我真不是行家，上次买i908的时候就选了好久，最后还是买贵了不少，呵呵。这次按照我的需要关注了如下几个手机。
    \n
    一、个人需求
    \n
    个人对手机的需求不是很赶“潮流”，认为够用就可以了，价格自然是越低越好，第一次用的是联想的i716，折叠的，而后就是丢掉的i908，直板的。目前认为直板的比较方便，不喜欢滑盖的。喜欢简约大气的类型，不喜欢花里胡哨的。
    \n
    个人喜欢在坐公交车的时候看看电子书（以前就是把PDF转成TXT直接看了不少技术文档）或者做些行程规划、事务处理（最好是联网的，以前手机不支持，非常喜欢这个功能），处理电子邮件（用的是Gmail，需要只是SSL和XHTML，以前的i908就不支持）。最好是有个拍照功能，喜欢随手拍些东西。最好有音乐功能（这两个貌似一般手机都支持了）。
    \n
    我还是比较看重手机品牌的，联想的我用过两个，质量还行，诺基亚的市场份额说明其质量不错。
    \n
    二、筛选过程
    \n
    1、联想i908
    \n
     
    \n
    \"\"
    \n
    最先看的是丢掉的那款，联想i908，我买的时候是1500多，现在商场报价大概在1100左右，网络报价有的只有900的样子，价格降了不少。加上我还剩余其配件（电板一块，耳机，充电器啥的都还在），选择这款的原因是这些配件不会浪费掉（因为都还比较新，浪费了实在可惜）。
    \n
    2、诺基亚N70
    \n
    \"\"
    \n
    这款机子我哥哥在用，试了下还是不错的，布局和功能都基本符合我的需求，且是一款智能手机（虽然不晓得用到的有多少，有朋友说 智能只是玩具，呵呵），价格大概在1700的样子，性价比还是挺不错的，
    \n
    3、诺基亚N73
    \n
    \"\"
    \n
    这款机子应该是很经典的啦，号称街机王，目前报价应该是2K以上，功能相当强大，也是一款智能手机。虽然上市有一段时间了，但是依然相当火爆。
    \n
    4、诺基亚 5310 XpressMusic
    \n
    \"\"
    \n
    这个手机我昨天在卖场看了下，商场给的价格还是2K以上，不过网上已经给出1900的价格，可是感觉太薄了，容易丢失。
    \n
    5、联想i909
    \n
    \"\"
    \n
    这个和i908差不多，估计原来的电池啥的还可以使用，屏幕大小也差不多，但是其定位是在“游戏手机”，我玩的不多。
    \n
    6、联想i968
    \n
    \"\"
    \n
    号称可以和N73相抗衡的手机，但是那个 蓝色的颜色我不是很喜欢。
    \n
    7、iphone
    \n
    \"\"
    \n
    这个只有看看的份，比较贵，且对其中文支持不放心，我不是mac迷，呵呵。
    \n
    其他的都还没来得及看，也没没有最终确定，有谁使用过如上手机的，说说感受哈，也希望能有人推荐其他的哈。

    Do you get annoyed when you have a SSH session open, visit your browser for a while, and then return only to find you were disconnected? Most home NAT routers are the cause of this. If your router doesn’t offer an option to not shut off idle connections, you are probably better off by setting a keep-alive setting.
    \n
    To do this, just open /etc/ssh/ssh_config on your home (client) computer. Add the following line:
    \n
     
    \n
    \n
    配置代码
    \n
      \n    
    1. ServerAliveInterval 180  
      2. \n
    \n
    \nThere you have it! Just remember now, if you leave SSH open accidentally, anyone else can get on it. Remember to close your session when finished.PS：If you’re using AbsoluteTelnet (for Windows), you can do this from the Options->Properties->Connection page. There is an option there to enable keepalives and you can specify the duration between them.

    不管我是使用linux的的SSH还是windows下的putty、SecureCRT还是AbsoluteTelnet，当我连接到服务器端 后，离开一会或者做点其他的事情，再回到SSH的时候，常常发现客户端自动掉出来了；有的时候甚至跑一个需要时间比较长的JOB的时候，还没跑完就掉出来 了，导致JOB跑了一半，等等。。
    \n所以一直在找解决这个问题的办法，今天在googleReader上找到了一个解决办法，如下：

    个人在线声望真的越来越被看重了，我一直在做的“技能云”的目的就是建立良好的个人声望，虽然目前国内的很多人还没有意识到这点，但毋庸置疑的是，真的越来越重要了，前段时间MR.6就写过一篇文章，几天又发现了一个文章专门说这个问题的，我也顺着这个思路说说看。
    \n
    先来看这篇文章“How To Manage Your Online Reputation”，文章中说到：You've spent a lot of time building up your reputation and image both online and off, so it's important to make sure that someone isn't out there dragging it through the mud. The latest tool for reputation management is Trackur, but its bottom-level price is $88/month, so the question on my mind, is: "Is it worth it?" There are already many different ways to monitor your online reputation as it is. Let's see how they stack up. 
    \n
    而后列举了几个可以使用的工具（网站）来管理自己的在线声望，其中提到了一个网站http://www.trackur.com/竟然是收费的，而且还不便宜，最便宜的还88美刀/月，另外还有像google通知等。详细的可以去看这篇文章：http://www.readwriteweb.com/archives/how_to_manage_your_online_reputation.php
    \n
    接着看上面说到的这个收费的网站，真的是个监视、管理个人在线声望的网站，价格也真不便宜，呵呵，看看他是怎么说个人声望的：
    \n
    Did you know that 52% of individuals put their trust in what others have to say about you?
    \n
    \nDid you know that 87% of consumers look at the reputation of your CEO, when judging your company's reputation?
    \n
    \nDid you know that 59% of hiring managers are influenced by your online reputation?
    \n
    \nDid you know that Trackur will monitor the web 24/7 and alert you whenever your reputation is being discussed?( 这条是宣传自己网站的）
    \n
    看看上面列举的几个数据，怎么来的，我们无法得知，但是其在一定程度上说明了个人声望是如何的重要，可能国外会更普及一点；但是对于国内来说，其他行业我不了解，至少和互联网沾边的，不如软件开发行业等，会比较看重的。
    \n
    都说国内什么都要落后老外们几年时间，但是值得我们高兴的事，我们这次我们的意识并没有晚，我们与2007年中开始做的”技能云“正是在这个方面的体现，我们希望的是通过用户的努力，创建良好的个人声望，并勇敢的把自己的声望show出去；此外，我们还将创建公司和项目的声望。
    \n
    虽然我们才刚刚起步，虽然很多人还不能意识到这点的重要性，但是我们相信，随着时间的推移，随着个人不断的体会和经历，加上技能云平台的不断完善，我们肯定会让所有的对自己声望在意的朋友建立起自己的”技能云“。

    转义正则表达式中的特殊字符
    \n===========================================
    \n使用Regexp.escape方法(别名方法是Regexp.quote)，可以把正则表达式中的特殊字符统统转义：
    \nstr1 = "[*?]"
    \nstr2 = Regexp.escape(str1)    # "\\[\\*\\?\\]"
    \n
    \nescape会转义掉[*?]这几个特殊的字符，但是其没有对另外一个字符‘/’进行任何处理，这个作为正则表达式的分隔符(//)中的字符难道不是特殊字符么。
    \n
    \n 看个例子：
    \npages="http://www.taojer.com/id=1&name=help"
    \nputs Regexp.escape(pages)
    \n
    \n 输出：
    \nE:\\Ysl\\Test>ruby exp.rb
    \nhttp://www\\.taojer\\.com/id=1&name=help
    \n
    \n可以看到其对/字符是没有进行处理的。
    \n
    \n这个可能会给如下这个需求带来一些问题：
    \n我想在一段String中找到所有以一个指定的URL开头的链接地址，程序大概是这样的：
    \nurl="http://www.taojer.com"
    \n按照我们的思路，可能会这么写：

    \nstr.scan(/<a href="(e_url)">(.+?)<\\/a>/m)
    \n但是这样就会因为/字符存在而异常咯？
    \n
    \n正确是应该是：

    在linux与windows平台间交换压缩包文件，如果文件名中含有中文，有时候就会遇到乱码问题，给平台间的文件交换带来麻烦。今天仔细研究了一下，总结下面一些经验，供大家分享
    \n
    1. 7zip和rar（我用的是3.50，好像rar的旧版本不行）会对文件名编码进行转换，内部文件名编码使用
    \n
    unicode，所以使用这两种格式在linux和windows平台间交换不会有乱码问题，其他格式（比如tar.gz, tar.bz2)似乎不进行转换，所以不适合平台间交换。但鉴于linux的自由精神，不推荐使用商业软件rar，而推荐自由的7zip。但是，我发现用 Ubuntu中（我的是Edge）file-roller处理7zip文件还是会存在问题，而用命令行就没有问题，所以推荐大家用命令行的7zip。
    \n

    \n按照找到的资料，应该只有文件名会出现乱码，正文内容不会乱码的呀，真是奇怪。

    \n1. 7zip和rar（我用的是3.50，好像rar的旧版本不行）会对文件名编码进行转换，内部文件名编码使用
    \nunicode，所以使用这两种格式在linux和windows平台间交换不会有乱码问题，其他格式（比如tar.gz, tar.bz2)似乎不进行转换，所以不适合平台间交换。但鉴于linux的自由精神，不推荐使用商业软件rar，而推荐自由的7zip。但是，我发现用 Ubuntu中（我的是Edge）file-roller处理7zip文件还是会存在问题，而用命令行就没有问题，所以推荐大家用命令行的7zip。
    \n
    \n按照找到的资料，应该只有文件名会出现乱码，正文内容不会乱码的呀，真是奇怪。
    \n
    \n我本地测试用7zip或者rar压缩以后，中文的文件名正常了，但是内部的数据文件中的中文还是乱码，奇怪呀。。。
    \n有高手指点一下，多谢了哦。

    这几天，项目上遇到一个很奇怪的问题，由于项目比较庞大，使用了3台独立的主机做服务器，前端用了硬件的radware采用轮询算法做了三台服务器的负载均衡，每台服务上部署了一台weblogic和一个前置apache做proxy，并且启用了apache的支持weblogic的集群功能，二次向三台weblogic做负载均衡（虽然这里我觉得没啥必要，但是原先他们就这么做了，我就不改了）。
    \n
    apache使用的是prefork模块，开了800个最大连接，配置了超时机制；后端的weblogic除了线程池和队列，文件句柄等做了修改外，其他的貌似没怎么修改。
    \n
    出现的问题的现象是，apache的线程全部用完（802个），weblogic相对比较空闲，内存消耗一般，CPU（4颗的）的idea也在50%左右；前端表现是页面打开速度相当慢，基本不可用。
    \n
    问题的分析过程是，先看到apache的error的log里面很多“文件找不到”错误，由于编辑做的页面上引了一些并不存在的资源，导致的，怀疑此类错误太多，会影响性能，于是找出错误页面，让编辑修复其中巍峨文件引用。但是效果不是很明显，虽然error少了很多。
    \n
    继续分析，使用netstat -an看到很多端口被占用，且很多处于CLOSE_WAIT状态，找个脚本统计下，如下：
    \n
    [wwwpps@IceskYsl]$ netstat -n | awk '/^tcp/ {++S[$NF]} END {for(a in S)  print a, S[a]}'
    \nLAST_ACK 1
    \nSYN_RECV 15
    \nCLOSE_WAIT 7729
    \nESTABLISHED  471
    \nFIN_WAIT1 3
    \nFIN_WAIT2 52
    \nSYN_SENT 1
    \nTIME_WAIT 725
    \n
    可以看到，确实很多，感觉这里是有问题，google得到一些资料，说到这个问题会导致：“大量的CLOSE_WAIT连接，直接占满TCP队列，导致Apache失去响应。”
    \n
    解决这个问题的方法是修改系统的参数，系统默认超时时间的是7200秒，也就是2小时，这个太大了，对于我们这样的负荷来说，于是修改如下几个参数：
    \n
    sysctl -w net.ipv4.tcp_keepalive_time=30
    \nsysctl -w net.ipv4.tcp_keepalive_probes=2
    \nsysctl -w net.ipv4.tcp_keepalive_intvl=2
    \n
    然后，执行sysctl命令使修改生效，基本上就算完成了。目前正在观察中，看看下午高峰时候效果如何，就可以基本上得出结论了。

    \n出现的问题的现象是，apache的线程全部用完（802个），weblogic相对比较空闲，内存消耗一般，CPU（4颗的）的idea也在50%左右；前端表现是页面打开速度相当慢，基本不可用。
    \n问题的分析过程是，先看到apache的error的log里面很多“文件找不到”错误，由于编辑做的页面上引了一些并不存在的资源，导致的，怀疑此类错误太多，会影响性能，于是找出错误页面，让编辑修复其中巍峨文件引用。但是效果不是很明显，虽然error少了很多。
    \n继续分析，使用netstat -an看到很多端口被占用，且很多处于CLOSE_WAIT状态，找个脚本统计下，如下：
    \n[wwwpps@IceskYsl]$ netstat -n | awk '/^tcp/ {++S[$NF]} END {for(a in S)  print a, S[a]}'
    \nLAST_ACK 1
    \nSYN_RECV 15
    \nCLOSE_WAIT 7729
    \nESTABLISHED  471
    \nFIN_WAIT1 3
    \nFIN_WAIT2 52
    \nSYN_SENT 1
    \nTIME_WAIT 725
    \n可以看到，确实很多，感觉这里是有问题，google得到一些资料，说到这个问题会导致：“大量的CLOSE_WAIT连接，直接占满TCP队列，导致Apache失去响应。”
    \n解决这个问题的方法是修改系统的参数，系统默认超时时间的是7200秒，也就是2小时，这个太大了，对于我们这样的负荷来说，于是修改如下几个参数：
    \nsysctl -w net.ipv4.tcp_keepalive_time=30
    \nsysctl -w net.ipv4.tcp_keepalive_probes=2
    \nsysctl -w net.ipv4.tcp_keepalive_intvl=2
    \n然后，执行sysctl命令使修改生效，基本上就算完成了。目前正在观察中，看看下午高峰时候效果如何，就可以基本上得出结论了。
    \n参考文章：

    今天看看如何在Rails中实现类似的功能,思路是一样的,可以缓存在数组或者Hash里面,这里为了查找方便,我们选择使用Hash.
    \n
    也就是:如何创建一个变量从rails开始运行时初始化，一直维持到rails终止，而且对于每一个request都能共享的变量？
    \n
    1,首先在environment.rb里面(如果您使用的Rails2以上版本,建议放在initializers目录里面,自己创建一个文件即可)定义一个ruby中的全局变量即可，例如$actions_in_mem在ruby里面，以$开头的变量即自动申明为全局变量）。在rails启动的时候，执行在environment.rb和initializers里面的文件，初始化$actions_in_mem,这样$actions_in_mem即可持续使用了,如:
    \n
    \n
    Ruby代码
    \n
      \n    
    1. $actions_in_mem = Hash.new  
      \n    
      2. \n
    \n
    \n
     
    \n
    2,然后在controller或者model或者view里面都是可用的了,比如在model里面实现刷新:
    \n
     
    \n
    \n
    Ruby代码
    \n
      \n    
    1. #刷新缓存  
      2. \n    
    2. def Action.refresh  
      3. \n    
    3.   Action.get_actions(1).each do |ac|  
      4. \n    
    4.     put_into_hash(ac.controller+"_"+ac.action,ac.id)  
      5. \n    
    5.   end  
      6. \n    
    6. end  
      7. \n    
    7.   
      8. \n    
    8. def Action.put_into_hash(key,value)  
      9. \n    
    9.   $actions_in_mem.store(key, value)  
      10. \n    
    10.   logger.info("@@actions_in_mem.size=\#{$actions_in_mem.size}---\#{key}=>\#{value}")  
      11. \n    
    11. end  
      \n    
      12. \n
    \n
    \n
    3,当然,你可以在controller中定义一个方法手工刷新这个全局变量,或者定时刷新即可,如下代码实现手工刷新.
    \n
     
    \n
     
    \n
    \n
    Ruby代码
    \n
      \n    
    1. #刷新缓存数据  
      2. \n    
    2. def refresh_actions  
      3. \n    
    3.   Action.refresh  
      4. \n    
    4. end  
      \n    
      5. \n
    \n
    \n
     
    \n
    4,最后是在view里面显示或者维护,如下代码段:
    \n
    \n
    XML/HTML代码
    \n
      \n    
    1. <ul>  
      2. \n    
    2.   <% $actions_in_mem.each do |key,value|%>  
      3. \n    
    3.     <li><%=key%>=><%=value%></li>  
      4. \n    
    4.   <%end%>  
      5. \n    
    5. </ul>  
      6. \n
    \n
    \n
    如上,就可以理解的差不多啦..

    Scout是Highgroove Studios写的一个很有趣的应用，他提供了一个大的框架，使得其他人可以以插件（集成）的方式实现他的方法（run），进而按照他预定的格式，将采集到的数据发送到其中央服务器，进而可以存储，并以报表的形式展示出来。
    \n我大概了看了下起实现方式，和插件的编写方式，其实也挺简单的，其原理也就是在*unix上可以采用crob之类的做定时调度，采集数据（可以使用系统的一些命令，比如ps,top)等等，再把数据组合成他预定义的格式就可以了。

    Elastic IP addresses are static IP addresses designed for dynamic cloud computing.    An Elastic IP address is associated with your account, not a particular instance,    and you control that address until you choose to explicitly release it. Unlike    traditional static IP addresses, however, Elastic IP addresses allow you to    mask instance or availability zone failures by programmatically remapping your    public IP addresses to any instance associated with your account. Rather than    waiting on a data technician to reconfigure or replace your host, or waiting    for DNS to propagate to all of your customers, Amazon EC2 enables you to engineer    around problems with your instance or software by programmatically remapping    your Elastic IP address to a replacement instance.

    2、功能实用，但有不足

    把应用迁移到新的服务器上以后，发现经常有”超时“的错误信息，如/usr/lib/ruby/1.8/timeout.rb:54:in `rbuf_fill': execution expired (Timeout::Error)，恩，应该是网络不稳定或者是服务器响应太慢的结果，需要捕获下这个异常并做些处理，记录如下：

    经历了Java/Rails的乱码洗礼，经过Zip/RAR/7zip等等的搔扰，经过不懈的恶补，偶以为面对乱码问题可以应对自如了，然而不幸的是，这次又遇到了，下面看过程。
    \n
    问题现象：
    \n
    1、在Rails中，上传本地的文件到服务器，服务器接收到以后，保存到服务器并记录其所在的路径，然后使用Rails中的 send_file来实现下载功能。我在本地开发环境上一切正常，但是在服务器上发生“找不到文件”的错误，SSH连进去看了下，原来保存在硬盘上时，中文文件名出现乱码，类似“2008_03_25_07_54_27_娣樺疂瓒呯骇鐢ㄦ埛鎼滅储寮曟搸.rar”这样的。
    \n
    2、在Rails中使用Ruby的File.new()、File.open()函数创建的文件，在硬盘上显示的中文名也是乱码。（这个人和我发现的问题类似：http://www.javaeye.com/topic/66371）
    \n
    问题分析及其定位：
    \n
    经过查找和分析，偶认为这与系统的字符集设置有关，因为在我本地开发机器上是可以正常显示和查看的，但是在服务器上就不可以，着重了解字符集的设置。
    \n
    分析过程：
    \n

    恩，是linux的系统。
    \n
    2、再看看目前的字符集
    \n

    \nLC_IDENTIFICATION="POSIX"
    \nLC_ALL=
    \n
    这是默认的POSIX。
    \n
    3、查看下系统支持的字符集
    \n
    locale -a
    \n
    修改方法：
    \n
    在/etc/bashrc中加入
    \nexport LC_ALL="zh_CN.utf8"

    最近有点蹊跷,老是遇到一些莫名其妙的问题,呵呵,折腾吧.今天要说的问题是,在ruby中调用系统(*UNIX)中的shell命令来做些事情,本来没啥难度的事情,我却遇到了一个费解的问题.
    \n
    问题描述:
    \n
    由于需要给用户打包下载一系列的文件(图片),为了方便,我在ruby中调用系统的rar来打包需要下载的资源,然后再send_file下载下去,但是这里却遇到了奇怪的问题,调用系统命令的那句出现问题.
    \n
    关于在RUby中调用系统的shell,大家可以参考如下文章( 6 Ways to Run Shell Commands in Ruby: http://pasadenarb.com/2007/03/ruby-shell-commands.html#comment-1886),我就不多废话了.直接看我的相关代码,如下:

      4. \n    
    4. logger.info("oo=\#{oo}")  
      5. \n
    \n
    \n上面的那个变量是按照时间取的唯一标识.这里使用的 %x{}(`)来获取执行的结果,以方便查看及问题定位,在本地机器(Ubuntu 7.10)上,一切正常,输出如下:\n

    最近有点蹊跷,老是遇到一些莫名其妙的问题,呵呵,折腾吧.今天要说的问题是,在ruby中调用系统(*UNIX)中的shell命令来做些事情,本来没啥难度的事情,我却遇到了一个费解的问题.
    \n问题描述:
    \n由于需要给用户打包下载一系列的文件(图片),为了方便,我在ruby中调用系统的rar来打包需要下载的资源,然后再send_file下载下去,但是这里却遇到了奇怪的问题,调用系统命令的那句出现问题.
    \n关于在RUby中调用系统的shell,大家可以参考如下文章( 6 Ways to Run Shell Commands in Ruby: http://pasadenarb.com/2007/03/ruby-shell-commands.html#comment-1886),我就不多废话了.直接看我的相关代码,如下:
    \n
    \n
    \nRuby代码
    \n
    \n    local_dir_name=1207667932_2  
    \n    logger.info("rar a \#{local_dir_name} \#{local_dir_name}")  
    \n    oo= %x{rar a \#{local_dir_name} \#{local_dir_name}}  
    \n    logger.info("oo=\#{oo}")  
    \n
    \n
    \n上面的那个变量是按照时间取的唯一标识.这里使用的 %x{}(`)来获取执行的结果,以方便查看及问题定位,在本地机器(Ubuntu 7.10)上,一切正常,输出如下:
    \n
    \n本地输出日志
    \n
    \n    rar a 1207667932_2 1207667932_2  
    \n    oo=  
    \n    RAR 3.70 beta 1 Copyright (c) 1993-2007 Alexander Roshal 8 Jan 2007  
    \n    Shareware version Type RAR -? for help  
    \n      
    \n    Evaluation copy. Please register.  
    \n      
    \n    Creating archive 1207667932_2.rar  
    \n      
    \n    Adding 1207667932_2/datas.csv OK  
    \n    Adding 1207667932_2/images OK  
    \n    Adding 1207667932_2 OK  
    \n    Done  
    \n
    \n
    \n
    \n但是在服务器上 (这里使用的是DH的PS服务器),其不能正常运行,如下:
    \n
    \n
    \n服务器输出日志
    \n
    \n    rar a 1207666290_2 1207666290_2  
    \n    oo=  
    \n    Program aborted  
    \n
    \n
    \n可以看到,如上发生了异常,但是原因无法得知.
    \n问题分析:
    \n奇怪的很,查了下环境,没啥不一样的呀,唯一发现不一样的是rar的版本不咋一致,DH上的rar版本比较老,分别如下:

    时常还是要在另外一台电脑上使用windows，也只能使用putty或者SecureCRT,连接到服务器上，但是一直以来，都存在一些小问题，这里以SecureCRT为例把解决方法汇总下。
    \n
    1、中文显示乱码的问题
    \n
    该问题的现象是用SecureCRT连接到服务器上，比如tail应用日志的时候，其日志中的中文不能很好的显示（也就是乱码）。这个问题的根本原因是双方的编码方式不一致，因为一般的来说，服务器上的编码是UTF-8（我的服务器是这样的，或者被我设定为这样的）你可以在服务器上使用locale 查看，而SecureCRT的默认设置的字符编码是保持系统一致的，在中文windows上就是GBK或者其他编码；
    \n
    知道原因修改起来就比较简单了，分为两个部分：
    \n
    1）修改远程linux机器的配置
    \nvim /etc/sysconfig/i18n
    \n把LANG改成支持UTF-8的字符集
    \n如：
    \nLANG=”zh_CN.UTF-8″
    \n或者是
    \nLANG=”en_US.UTF-8″
    \n
    或者是修改指定用户的locale，编辑.bashrc文件，导入以上的编码即可。
    \n
    2）然后再改Secure CRT的设置
    \nOptions -> Session Options ->  Apperance -> Fonts -> Character（选项->会话选项->外观->字符编码->uft-8）
    \n
    \n退出，再重新登录。发现utf8的文件都能正确读了，utf8的文件名也能正确显示了。
    \n
    2、显示颜色
    \n
    显示颜色是个好习惯，一来直观明了，二来增加美感，对视力也有好处，在Secure CRT中设置显示颜色也比较简单，如下：
    \nOptions -> Session Options ->Terminal ->Emulation ->ANSI Color 选中就可以了。
    \n
    3、字体选择
    \n
    选择不同的字体，可以显示不同的效果，按照个人喜好，比如我自己就喜欢细一点的，清晰一点的字体，而这个字体在Secure CRT是可以设置的，其默认的是vt100，我个人比较喜欢“新宋体”的显示效果。（PS.很多人喜欢fixedsys 字体）。设置方法也很简单，如下：Options -> Session Options ->  Apperance -> Fonts 选择你需要的字体即可。

    今天在月光的blog上看到其对DreamHost的抱怨，说起存在“过度销售”的现象，具体的可以看这里（http://www.williamlong.info/archives/1301.html）。
    \n
    这里说说我自己使用过的和了解到的国外服务器提供商的个人感受，纯属个人感受，请不要乱扣帽子。我选空间的用途主要是有2个，其一是运行一些我开发的开源的系统（比如1stlog，byeloo！等）的Demo，用来演示或者流量不大的应用；其二是为客户选择的跑商业化的RoR应用。所以我选择的服务区必须可以支持RubyOnRails应用。
    \n
    我使用过的国外提供商有BlueHost，DreamHost和SliceHost，我试用过的有亚马逊的EC2，RaislHost,hostingrails和railsplayground；我了解过的有mt和Railsmeches，如下分别说说个人感受：
    \n
    1、BlueHost：这个是我最开始使用的国外的服务器，当时是从朋友那分了一些空间过来使用的，因为最开始的时候，Rails的服务器并不多，貌似只有BH和DH吧，呵呵，BH虽然支持Rails，但是限制相当多，我记得当时我写的“技能云”就放上面，那次被InfoQ报道了下后，那天流量稍微大些，就撑不住了。且速度一般般，映像不咋好，后来就撤离了。
    \n
    2、DreamHost：这个我使用的时间比较长，包括现在这个blog也是放在上面的，总的来说，马马虎虎，只能用来放个人blog和一些Demo等，不适合做商业站点使用；我开始使用的是Share模式的，但是后来开发的一个系统需要在后台跑一些定时JOB，其不支持，就只能开通其PS服务（这个速度相当慢，我等了20多天，来来回回的交互了好多次邮件，他们都说申请开通PS的客户太多，他们忙不过来，需要耐心的等，后来最后我怒了，说再不搞好，我就给我所有的客户选择SliceHost，这招见效，立马搞定，推荐大家使用，哈哈）。
    \n
    其Share模式的用户非常的多，月光说他的那个服务器上有380个shell用户和1600多的FTP，都是很正常的，主要是其销售模式，带来巨量的用户群，而其宣称的500G空间和5T的月流量，无限子域名，无限MYSQL库等等，都是扯淡的，为了吸引眼球和骗那些新入手的朋友，他们对CPU和内存的限制非常严格（这就是他们的高明之处），一旦超过内存和CPU，你必须升级到PS模式。
    \n
    而升级到PS模式（最低是150M内存/150MHZCPU/15美刀/月，以此随自己调解，以10MHZcpu/10M内存/1美刀/月的价格）以后，他会再三提醒您，如果mem不够，请增加自己的内存等。
    \n
    虽然PS号称是”私有服务器“，其效果和许诺的CPU和MEM都可以得到保证，但是也不是很稳定，毕竟用户群那么大，出问题的小概率事件也会很多的。
    \n
    值得称道的是，他们的技术支持还是不错的，我每次发邮件问，基本上很快就给我比较明确的答复；另外，DH的网速还是不错的（就我使用的那个服务器看）；其操作面板比较容易操作，也非常强大。付款比较方便，支持信用卡，paypal以及google checkout等。
    \n
    总的来说：DH的share模式比较适合流量小的和一些demo演示之类的应用，不适合商业化的服务；PS模式稍微好点，但是要做好down机的准备，呵呵。
    \n
    3、SliceHost：这个应该是最便宜的VPN提供商了，其比较专业，以VPN的方式提供服务，可以选择的种类最低是256M独立内存，可以自己选择操作系统类型，自己装web服务器等，其技术文档比较多且可操作性比较好，但是其技术支持不是很到位，我只在chat里和他们沟通过，没发过邮件。
    \n
    SliceHost我上次使用的是256M的ubuntu7.10+nginx+mogrel集群跑的一个Rails应用，用apache的ab压力测了下，效果还不错，且没有出现down机等不稳定现象的出现，比较令人满意。
    \n
    但是有个问题，需要注意，我当时需要在程序里么net/http 取国内一些网站上的资源，速度很让人郁闷，有时候竟然只有900B/秒，相当慢。我曾和他们的技术支持沟通，他们给的解释是“SliceHsot在美国，而您要取得资源在中国，这个网路上的事情，我们也无能为力”，所以，如果您有类似需求，请千万注意。
    \n
    其他几个，类似EC2和Mt等，由于我没有实际长时间使用过，这里就不评价了，最近会逐一试试，以后再补充这个文章。
    \n
    如果您使用过其他的国外的服务器，还请分享一二；或者想更多的了解我使用过的这些服务器，请留言即可。

    \npre_match和post_match这两个方法以前没使用过，他们分别是用来获取当前匹配结果的前一个和后一个匹配结果,看个例子既可以明白了. 
    \n
    \nRuby代码
    \n
    \n    # #这个是分析URI的    
    \n     def self.split_uri( uri_str )    
    \n         m = %r<http://([^/]+)>.match(uri_str) or raise ArgumentError, "cannot parse URI: \#{uri_str}"    
    \n         host = m[1].strip    
    \n         path = m.post_match    
    \n         path = '/' if path.empty?    
    \n         puts host, path    
    \n    # end  
    \n      
    \n    url = http://www.1sters.com:80/this_is_a_string/and_this_is_too    
    \n    puts(split_uri(url))  
    \n    #  
    \n    #Outout:  
    \n    #www.1sters.com:80,this_is_a_string/and_this_is_too    
    \n
    \n
    \n如上这段代码很好的说明了post_match的作用.

    由于打算将我的第一个开源项目1stlog重构和完善，看了下以前的实现方式，除了用到了很对rails2不支持的方法和插件外（正在着手修改），还用到了Rails中的component的。而这正是被很多railser们告诫要小心的地方，甚至有人说component是evil的，新版1stlog发布在即，我得好好了解下component为什么evil。
    \n
    一、为什么当时选择component
    \n
    选择component是根据当时的设计需求来的，1stlog设计的时候是作为一个只有基本blog功能的大框架，而其他的一些个性化功能，需要由其他开发人员或者爱好者来按照一定的规范开发和编写，当时认为，使用component时自简单有效的策略，您可以参考我当时编写”1stlog插件开发指南“。
    \n
    二、为什么说component是邪恶的
    \n
    有人说Rails中的component是邪恶的，千万不要使用，原因呢，还真不清楚，看到有人这么写：\n
    \n
    Using Components  
    \n
    \n \n
      \n    
    1. Components don’t belong in Rails. Don’t use them. They weren’t an 
      \n    
      2. \n    
    2. extraction. They weren’t well planned. When you want to use a 
      \n    
      3. \n    
    3. component it is probably because you misunderstand them or 
      \n    
      4. \n    
    4. really want a partial. Rethink what you’re doing. 
      \n    
      5. \n    
    5. The rest of the Rails world has written off components for a 
      \n    
      6. \n    
    6. reason and they’ll probably be deprecated by 2.0. Resist.  
      7. \n
    \n
    \n
    \n
    也有人拿typo中使用component导致响应很迟钝的数据说明，可以参考“Components may not be evil, but they sure can be slow”，再看看Rails的DHH咋说的呢？哦，他说”Why engines and components are not evil but distracting“
    \n
    这么看来，component并不邪恶了，只是慢一点，有些小问题罢了。
    \n
    三、还用不用？
    \n
    竟然大家都持谨慎态度，那么我们还用不用呢？用！但是或许得换个方式用。此话怎么讲？因为有一个既可以实现component功能，又不evil的东西出现了，那就是Cells，何谓Cells？还是看他的自白好了：
    \n
    \"\"
    \n
    \n
    A rails plugin to push things towards component-oriented architecture. Controller logic and views are encapsulated in lightweight cells and can be rendered like render_component.
    \n
    \n
    哦，看来是个好东西，还想多了解点，看看这些文章吧，"Cells: Bringing Components Back Into Rails 3"或者中文简要版本”插件Cells：把模块化带入Rails 应用中，组件导向轻量级的开发“，还可以看看道喜的简介”Rails框架：组件理念是否重返Rails框架“，或者看看中文的一个简单那的例子”有人用过cell么？“，如果想更深入的了解，可以看看”Ruby Component Web Frameworks“
    \n
    四、还有更好的？
    \n
    我是不知道了，您要是知道的话，还请告诉我。

    \n二、为什么说component是邪恶的
    \n有人说Rails中的component是邪恶的，千万不要使用，原因呢，还真不清楚，看到有人这么写：
    \n
    \nUsing Components  
    \n
    \n 
    \n
    \n    Components don’t belong in Rails. Don’t use them. They weren’t an 
    \n    
    \n    extraction. They weren’t well planned. When you want to use a 
    \n    
    \n    component it is probably because you misunderstand them or 
    \n    
    \n    really want a partial. Rethink what you’re doing. 
    \n    
    \n    The rest of the Rails world has written off components for a 
    \n    
    \n    reason and they’ll probably be deprecated by 2.0. Resist.  
    \n
    \n
    \n
    \n也有人拿typo中使用component导致响应很迟钝的数据说明，可以参考“Components may not be evil, but they sure can be slow”，再看看Rails的DHH咋说的呢？哦，他说”Why engines and components are not evil but distracting“
    \n这么看来，component并不邪恶了，只是慢一点，有些小问题罢了。
    \n三、还用不用？
    \n竟然大家都持谨慎态度，那么我们还用不用呢？用！但是或许得换个方式用。此话怎么讲？因为有一个既可以实现component功能，又不evil的东西出现了，那就是Cells，何谓Cells？还是看他的自白好了：
    \n
    \n
    \nA rails plugin to push things towards component-oriented architecture. Controller logic and views are encapsulated in lightweight cells and can be rendered like render_component.
    \n
    \n哦，看来是个好东西，还想多了解点，看看这些文章吧，"Cells: Bringing Components Back Into Rails 3"或者中文简要版本”插件Cells：把模块化带入Rails 应用中，组件导向轻量级的开发“，还可以看看道喜的简介”Rails框架：组件理念是否重返Rails框架“，或者看看中文的一个简单那的例子”有人用过cell么？“，如果想更深入的了解，可以看看”Ruby Component Web Frameworks“
    \n四、还有更好的？
    \n我是不知道了，您要是知道的话，还请告诉我。

    开始写这个之前，我不得不佩服下Amazon，不用说别的，就其SimpleDB，S3,EC2这几个就足以让业界大为惊叹，这些都比较熟悉了，今天说的是另外一个类似的东西，Amazon Simple Queue Service（SQS）。
    \n
    看名字，大概就可以猜出大概的意思了，对，就是队列服务，SQS就是一个简单的队列服务，你可以创建一个队列，然后从不同的地方往里面放东西，然后又可以在不同的地方不停的往外取东西，想想看，这不就是分布式协作么。
    \n
    但是需要注意的是，往里面放的时候，消息必须是txet，也就是是说不能放Hash或者数组啥的，如果您有类似需求，请接着往后看，我将提供一个变通的方法。
    \n
    一、简介SQS
    \n
    Amazon Simple Queue Service (Amazon SQS) offers a reliable, highly scalable, hosted queue for storing messages as they travel between computers. By using Amazon SQS, developers can simply move data between distributed components of their applications that perform different tasks, without losing messages or requiring each component to be always available.
    \n
    二、如何使用
    \n
    Ruby的社区足够活跃，每个应用都能找到对应的Gem或者插件，这给了我们足够的方便，针对SQS，我推荐的两个gem，分别是：
    \n
    1、SQS Gem
    \n
    \n
    这个插件是Amazon SQS官方站点写的教程《Using Amazon S3, EC2, SQS, Lucene, and Ruby for Web Spidering》上使用的，足够的简单，但是其主页貌似访问不了了，只能通过Google Cach看看。
    \n
    使用非常方便，流程如下
    \n
    1）安装：gem install SQS
    \n
    2）测试：ruby test/all_tests.rb
    \n
    3）使用示例\n
    \n
    Ruby代码
    \n
      \n    
    1. require 'rubygems'  
      2. \n    
    2. require 'sqs'  
      3. \n    
    3.   
      4. \n    
    4. SQS.access_key_id = 'YOURACCESSKEYID'  
      5. \n    
    5. SQS.secret_access_key = 'YOURSECRETACCESSKEY'  
      6. \n    
    6.   
      7. \n    
    7. q = SQS.create_queue 'myFantasticQ'  
      8. \n    
    8. puts q.url  
      9. \n    
    9.   
      10. \n    
    10. SQS.each_queue do |q|  
      11. \n    
    11.   puts q.name  
      12. \n    
    12. end  
      13. \n    
    13.   
      14. \n    
    14. q = SQS.get_queue 'myFantasticQ'  
      15. \n    
    15.   
      16. \n    
    16. q.send_message 'This is a message!'  
      17. \n    
    17.   
      18. \n    
    18. m = q.receive_message  
      19. \n    
    19. puts m.body  
      20. \n    
    20. m.delete  
      21. \n    
    21.   
      22. \n    
    22. q.each_message do |m|  
      23. \n    
    23.   # note that #each_message is an infinite loop!  
      24. \n    
    24.   # you must either break out of it, or delete each message you receive  
      25. \n    
    25.   m.delete  
      26. \n

    32. q.delete  
      33. \n
    \n
    \n其他文章，可以自己Google。
    \n
    2、RightScale gems
    \n
    RightScale gems是RightScale 从其产品里面提取出来的，这个现象很常见，就像Shopify 中提取的Active Merchant一样，从一个成熟的产品中提取出来一个gem，其可用性是相当高的。
    \n
    使用方法大同小异，不再赘述，如果感兴趣，请到上面的地址上自行查看。
    \n
    三、如何扩展
    \n
    前面我们说了，SQS中容纳的消息是text的，但是看其文档表述，是这样写的：
    \n
    \n
    New messages can be added to a queue at any time. The message body can contain up to 8 KB of text in any format.
    \n
    \n
    any time？啥意思？奇怪。
    \n
    我认为一种可行的办法是，把Hash转成ymal格式的（.to_yaml），然后放进去后；取出的时候，直接YAML.load(message.body)，然后再还原即可了。
    \n
    看段代码，如下：
    \n
    \n
    \n
    Ruby代码
    \n
      \n    
    1. require 'SQS'  
      2. \n    
    2. class Tsqs  
      3. \n    
    3. SQS.conf_file = 'sqs_conf.yml'  
      4. \n    
    4. s = SQS.new  
      5. \n    
    5. puts s.api_version  
      6. \n    
    6. puts s.conf_file  
      7. \n    
    7. puts s.url_for_query  
      8. \n    
    8. iceskysl = s.get_queue('iceskysl_message')  
      9. \n    
    9. books_to_update = { 'bookid'=>"1",'url'=>"url1",'queue'=>"queue1"}  
      10. \n    
    10. iceskysl.send_message(books_to_update.to_yaml)  
      11. \n    
    11.   
      12. \n    
    12. iceskysl_messages = iceskysl.receive_messages  
      13. \n    
    13. puts iceskysl_messages.size  
      14. \n    
    14. iceskysl_messages.each do |message|  
      15. \n    
    15.  params = YAML.load(message.body)  
      16. \n    
    16.  puts "bookid=" + params[:bookid] + ",url=" + params[:url] +  ",queue=" + params[:queue]  
      17. \n    
    17.   message.delete  
      18. \n    
    18. end  
      19. \n    
    19. end  
      20. \n
    \n
    \n看明白了么，没问题吧，呵呵。另外，这里还有一篇文章使用的是RightScale gems。
    \n

    \n 
    \nGoogle Docs now allows you to view and edit your documents offline, without an internet connection. To do all of this, Google Docs uses Google Gears, an open source browser extension that adds offline functionality directly to the browser.

    \n
    Dear Amazon Web Services developers,\n
    We've often told you that one of our goals is to drive down costs continuously and to pass those savings on to you. We have been able to reduce our costs for data transfer, so we're pleased to announce that we're lowering our pricing for data transfer, effective May 1, 2008. You'll notice below that we've reduced price at every existing usage tier of transfer out, as well as added an additional tier for the heaviest users.
    \n
    Current data transfer price (through April 30, 2008)
    \n$0.100 per GB - data transfer in
    \n$0.180 per GB - first 10 TB / month data transfer out
    \n$0.160 per GB - next 40 TB / month data transfer out
    \n$0.130 per GB - data transfer out / month over 50 TB
    \n
    Data transfer "in" and "out" refers to transfer into and out of the Amazon service. Data transferred between Amazon EC2 and Amazon S3-US, Amazon SimpleDB and Amazon SQS is free of charge (i.e., $0.00 per GB). Data transferred between Amazon EC2 and Amazon S3-Europe will be charged at regular rates.
    \n
    New data transfer price (effective May 1, 2008)
    \n$0.100 per GB - data transfer in
    \n$0.170 per GB - first 10 TB / month data transfer out
    \n$0.130 per GB - next 40 TB / month data transfer out
    \n$0.110 per GB - next 100 TB / month data transfer out
    \n$0.100 per GB - data transfer out / month over 150 TB
    \n
    Data transfer "in" and "out" refers to transfer into and out of the Amazon service. Data transferred between Amazon EC2 and Amazon S3-US, Amazon SimpleDB and Amazon SQS is free of charge (i.e., $0.00 per GB). Data transferred between Amazon EC2 and Amazon S3-Europe will be charged at regular rates.
    \n
    The result of this pricing change is that all customers will see a reduction in the price of transfer out. For example, a customer transferring 50TB a month will save 16% and a customer transferring 500TB a month will save 26% on transfer with the new pricing. Please see http://aws.amazon.com for full pricing information for each service.
    \n

    \nThe Amazon Web Services Team

    AWS越来越成熟,在继支持静态IP和固定存储后,这又是一个大的变化,如果啥时能使得国内的访问速度提上去的话,对国内的WEB人员将是最大的幸福了.继续期待...

    由于我是使用Xfce的,所以最开始升级的时候忘记升级相应的xfce了,导致后来启动的时候,没有UI界面,并遇到了scree not found的问题;然后修复了小企鹅输入法的方块问题,并做了些美化.
    \n
    这些问题google都是可以找到答案的,我也没具体记是咋整的,呵呵,反正是可以解决的.
    \n
    4.安装了NB6.1版本
    \n
    差不多搞了一下午,,中途睡了一觉,遇到一些问题都解决了,呵呵,但没感觉到8.04的有啥不一样的地方,哈哈..

    正如前面的这篇文章说的,Ubuntu8.04和NB6.1都发布了,我自然得抓紧升级了,正好今天调班在家休息,一觉睡到12点多,起来开始升级,先把重要的资料备份到另外一台电脑上,然后按照google出来的资料升级,我是用命令行升级的.
    \n1.修改源地址
    \n我以前的源很乱,正好这次一并清理下,把以前的 710的时候的源备份下,然后测了下google出来的那些源,选了个台湾的最快,(后来升级的时候发现这个源上有几个包当时下载不了,后来又加了一组上海电信的源)

    上面这个图片来源于slideshare上的一个PPT“Using Amazon SimpleDB with Ruby on Rails”，正如我上面截取的这个图片说的：
    \n
      \n    
    • 静态文件存储在S3上；
      • \n    
    • App server使用课余无限扩展的EC2；
      • \n    
    • 结构化数据存储在SimpleDB上；
      • \n    
    • 客户端/服务端的交互使用SQS；
      • \n
    \n
    看看AWS的几个应用，正好覆盖了WebApp的整个过程，以下逐一介绍下这几个服务：
    \n
    1、S3看上去就是一个大的硬盘，你可以把App中的所有数据都放上去，取回来，展示等等，是个比较安全的存储服务，省略了自己买磁盘阵列，维护等等费用，且号称是安全的。
    \n
    2、EC2的最大卖点就是其可以无限伸缩的，号称可以扩展到“云”上去，不用因为您的服务器压力过重而购买一批一批的机器，免得找机房，等等，可谓相当方便，在其推出固定IP和固态存储之后，使得EC2相当成熟；
    \n
    3、SimpleDB推出的最早，但是一直没仔细看，以为其和S3差不多，今天仔细看了下，其实不然，看其名字是SimpleDB，是用来替代DB的，但是比普通的DB更加Simple，其实也就是一个结构化的存储，你可以把DB的东西（表，行）组合一下放进去，然后根据其有的API查询和存贮，省了维护数据库的人力物力，但是速度不晓得如何。
    \n
    4、SQS是前段时间了解的，不晓得这个服务当初推出的典型应用场景是什么样的，就我的理解，其就是一个队列，相当于一个缓冲队列，用在分布式处理或者作用同步上相当不错，有兴趣的可以看我以前的文章“Amazon SQS,分布式作业不再费心”。
    \n
    总的来说，AWS的几个服务都是将WebApp开发中涉及到的几个方面分拆出来做成服务，以来提供便捷，二来自己赚了一大笔，真是聪明，不过这些应用的维护不晓得Amazon 是怎么处理的，肯定不会是我们常见的人工维护，估计和Google存储差不多的自维护系统。
    \n
    如果您对AWS感兴趣，如果您和笔者一样使用的是RubyOnRails，你可以使用RightAws插件，其包含了以上4个应用的实现，相当不错。
    \n
    但是其不足之处依然存在，例如多国内用户，速度不敢恭维；也有人列举了“Top 10 Reasons to Avoid the SimpleDB Hype”,当然也有人针锋相对的回应了这10个问题“ Top 10 Reasons to Avoid Document Databases FUD  4 ”；另外还有其价格是否真的划算（现在支付美刀比较划算），以及其曾经出现过的问题，所以您在决定使用之前还请仔细考量，这几个应用我都有过尝试，虽然没有大规模的使用，但是基本上比较了解了，如果您有问题，或者其他的经验，欢迎和我交流。

    1、Gmail与Google在线办公结合
    \n
    可以通过设置Gmail的过滤器为“有附件”且包含“DOC or XML”关键字的邮件转发到您的GoogleDoc的“Email-In Your Documents and Files"中，详细说明可以参考”Gmail过滤器妙用 之与Google在线办公结合“。

    2、Gmail Labels和过滤器结合在备份中的妙用
    \n
    Gmail的lable功能很强大，和上面说的过滤器结合可以做很好的备份用，例如我订阅了很多的邮件列表，想nginx，mogrel等等，这些邮件列表相当活跃，如果每次都如inbox，会严重干扰我其他的邮件，这时lable和过滤器就可以结合来做归档了，详细的操作方法请参考”Gmail Labels在备份中的妙用“

    \n好消息，发现一名学生了  
    \n绮梦 10:28:00

    \n绮梦  10:28:33 
    \n拖出来了，医生在抢救 
    \n绮梦 10:28:56

    \n绮梦 10:29:07  
    \n交通太困难 
    \n绮梦 10:29:42 
    \n现在还不一定，这个看样子看活着，吊瓶氧气都挂上了 
    \n绮梦 10:31:06  
    \n啊，又塌了 
    \n绮梦 10:31:28 
    \n突击队一个人被埋进去了

    \n绮梦 10:37:16  
    \n最新消息，彭州被困的10万群众危险！！！ 
    \n绮梦 10:38:49  
    \n由于大雨的影响，工程兵几次架桥失败，附近已经出现泥石流迹象，电话直接是叫通总理的，情况很危险！！！ 
    \n绮梦 10:39:19  
    \n由于桥梁倒塌，彭州市10万群众被堵在山中，救灾人员和物资无法运人。已经出现泥石流迹象 
    \n绮梦 10:41:11  
    \n总理电话里大喊，我不管你们怎么样，我只要这10万群众月兑险，这是命令。他把电话摔了 
    \n绮梦 10:41:33  
    \n头一次看见老爷子这么厉害 
    \n绮梦 10:41:54 
    \n汶川现在还没通知去，估计情况不是很好

    \n我现在在直升机上，估计一个小时后就到什肪了 
    \n绮梦 11:34:40  
    \n最新消息，汶川的映秀、漩口、卧龙三镇通讯信号很弱，至今也无法联系。估计三镇有将近两万多人被困，余震不断，大雨连绵，情况非常严峻，由于能见度太差，无法判断准确情况。总参命令，当空降部队到达汶川上空时，如果条件不允许，就不惜代价强行伞降！  
    \n绮梦 11:36:38 
    \n没有，飞机要进人雷区了，我要关机了，等会再和你们聊。

    \n
    \n
    CSRF这种攻击方式虽然提出来很久（在2006年的时候就有了）了，但是这个沉睡的攻击巨人直到前不久才逐渐走入我们的视线，到底CSRF是啥，危害到底有多大？常见的利用方式是如何的，今天作为“安全相关 | Security”分类的第一篇文章，我按照自己的理解告诉你，不要低估了CSRF危害性和攻击能力。
    \n
    \n一、什么是CSRF
    \n先看看CSRF的原文说明，如下：
    \n
    \n
    Cross Site Reference Forgery works by including malicious code or a link in a page that accesses a web application that the user is believed to have authenticated. If the session for that web application has not timed out, an attacker may execute unauthorized commands.
    \n
    二、CSRF案例说明和分析
    \n自然，这里拿Rails程序来举例子说明这些问题，大家知道Rails2之前是把session放在服务器端（文件或者DB或者缓存中），客户但在 cookie中保存sessionid；而到了Rails2后，还有一种方式是把session放在基于cookie的客户端中。当然这两样都各有道理， 各有优劣，不在我们这次说的范围之内。我们继续说，当我们向一个域名发送一个请求的时候，如果本店存在这个域名的cookie，浏览器会自动的把 cookie附带上。这样本来没有啥问题，也是我们为了解决http无状态记录的解决方案，但是有个问题出现了，如果出现一个到其他域名的请求，浏览区在 加载的时候，也把cookie给带上了，会有什么问题？我们举个简单的也很常见的例子来说明这个问题。
    \n-----------------------------案例------------------------------
    \n1、Bob在自己的电脑上刚刚查看完自己的银行A账户余额，然后比较无聊就跑到一个公开的BBS上灌水，当他看到一篇“银行A的内部照片”的帖子，很有兴趣的打开这个帖子想看看自己信任的银行A的内部图片是啥样子的，殊不知，这其实是一个attacker精心设计的骗局。
    \n2、在这个帖子中确实有几个图片，看上去真的像是银行A的照片，但是其中有个图片没显示出来，Bob以为是自己网速太慢，导致这个图片没有加载进来，也没在意。只是对这些并不是十分满意的照片摇摇头，就关了这个帖子。
    \n3、几天后，Bob猛然发现自己在银行A的账户上少了1000元，到底是怎么了？
    \n
    \n分析：
    \n为什么钱少了呢？我们得分析一下上面这个案例，好记得当时Bob说有个图片没显示么，是的，我们来看看这个图片的地址,惊奇的发现是：<img .src="http://www.banka.com/transfer?account=myself&amount=1000&destination=attacker">，这是一个什么地址？聪明的您一定很快就能明白，这个地址是邪恶的，看上去，他的意思是打开这个地址的人，给attacker转了1000元。
    \n这怎么可能？你肯定急了，我怎么能随便给一个人转1000元呢，而且我都不知道呀！但是，注意了，这其实是完全有可能的。还记得当时Bob刚刚查看完整及的帐号信息，基于银行A的cookie并不过期，当出现如上链接出现在src的时候（    note that .src is meant to be src），浏览器尝试着按照本地的cookie去加载上面这个URL，而银行A验证了来源请求的cookie是可以的，所以就这样事情就悄悄的发生了。
    \n    -------------------------------案例结束---------------------------
    \n
    \n    ok，看明白了么，这就是CSRF，一句话给他下个定义就是：借你的cookie在你不知道的时候悄悄的做了一些你不愿意做 的事情。恶日期这里有个更要命的是，这个包含上述URL的图片或者链接，并不需要一定是放在银行A的服务器上，相反可以在任一地方，比如blog，公开的 BBS，或者一些群发的Mail中等等，如此多的场合下，这些都有可能存在陷阱。
    \n再看一副图片吧，其说明的正是CSRF的攻击原理。
    \n\"\"
    \n
    \n 三、CSRF的预防
    \n看上去很恐怖吧，是的，确实恐怖，意识到恐怖是个好事情，这样会促使你接着往下看如何改进和防止类似的漏洞出现。
    \n总体来说，预防CSRF主要从2个方面入手，分别是：
    \n1、正确使用GET,POST和Cookie；
    \n2、在non-GET请求中使用Security token；
    \n
    \n    一般上，大家知道的浏览器发送请求的方式有GET或者POST，但是还有一种比较常用的是Cookie，至于其他的HTTP协议请求方式，你可以google，一般按照W3C的规范：
    \n1、GET常用在查看，列举，展示的时候；
    \n2、POST常用在下达订单，改变一个资源的属性或者做其他一些事情    ；
    \n
    \nok，我们这里拿Rails按照前面列举的2种预防手段做说明，首先，我们可以在Rails的控制权中（controller）将一些方法（action）限定（verify）为只能使用POST或者GET，例如：\n
    \n
    Ruby代码
    \n
      \n    
    1. verify :method => :post, :only => [ :transfer ], :redirect_to => { :action => :list }   
      2. \n
    \n
    \n恩，很好，这样做下限制以后，前面案例中的方法就失效了，因为这里我们限定了transfer必须使用POST来提交请求，当GET请求来的时候并不会被响应。
    \n万事大吉了？NO！因为POST的请求也是可以被构造出来后自动发送的，如何实现，看下面吧，你肯定会吃惊的。
    \n
    \n
    XML/HTML代码
    \n
      \n    
    1. <a .href="http://www.1sters.com/" onclick="var f = document.createElement('form'); f.style.display = 'none'; this.parentNode.appendChild(f); f.method = 'POST'; f.action = 'http://www.example.com/account/destroy'; f.submit();return false;">点我试试</a>  
      2. \n
    \n
    \n是的，这就是一个活生生的例子(.href is meant to be href)，使用link的href或者img的src都可以的，再想想一个Attacher放了一个图片，然后写了一个    onmouseover方法，执行上述的那段JS，如下，或者使用AJAX。\n
    \n
    XML/HTML代码
    \n
      \n    
    1. <img .src="http://www.harmless.com/img" width="400" height="400" onmouseover="…" />  
      \n    
      2. \n
    \n
    \n所以，限定为POST后还不是非常的保险，怎么办？不急，我们还有第二步，给non-GET的请求设置 security token，如何实现，在Rails2以后非常简单（也是默认的），我们只需要在environment.rb中添加如下代码：
    \n
    \n
    Ruby代码
    \n
      \n    
    1. config.action_controller.session = {  
      2. \n    
    2.   :session_key => '_csrf_session',  
      3. \n    
    3.   :secret      => 'ae4b43dda38ff78bb50898b2935da76d1e224061ab72a9399d34cea4c6178eee6dae815fff920a20642f27abda83b793da4e9b6cf20c4838805e80abf53e318a'  
      4. \n    
    4. }  
      5. \n
    \n
    \n然后    在application controller中包含如下security token设置：
    \n
    \n
    Ruby代码
    \n
      \n    
    1. protect_from_forgery  :secret => '053cef294a333f72c3584311799c69d2'  
      2. \n
    \n
    \nok，基本上安全了，如果这时POST请求过去，但是    security token和session计算出来的secret和服务端的secret匹配不上的话，就会返回一个ActionController::InvalidAuthenticityToken错误，防止该类缺陷的出现。
    \n安全了，也许你要说，那我如果能破解出    protect_from_forgery，不进OK了么，按照理论上是，但是实际是破解是基本上不可能的，因为有人曾计算过，暴力破解该串大概需要2的11次方时间，后续我将再写一篇文章详细的介绍，这里不再赘述。
    \n
    \n    四、总结
    \n总的来说，CSRF的兴起刚刚开始，网络上肯定会有一股热潮，Railser们一定要注意自己的程序的安全性，CSRF比你我能想到的更有威胁，千万别小瞧了它。

    \n2、在这个帖子中确实有几个图片，看上去真的像是银行A的照片，但是其中有个图片没显示出来，Bob以为是自己网速太慢，导致这个图片没有加载进来，也没在意。只是对这些并不是十分满意的照片摇摇头，就关了这个帖子。
    \n3、几天后，Bob猛然发现自己在银行A的账户上少了1000元，到底是怎么了？
    \n
    \n分析：
    \n为什么钱少了呢？我们得分析一下上面这个案例，好记得当时Bob说有个图片没显示么，是的，我们来看看这个图片的地址,惊奇的发现是：<img .src="http://www.banka.com/transfer?account=myself&amount=1000&destination=attacker;">，这是一个什么地址？聪明的您一定很快就能明白，这个地址是邪恶的，看上去，他的意思是打开这个地址的人，给attacker转了1000元。
    \n这怎么可能？你肯定急了，我怎么能随便给一个人转1000元呢，而且我都不知道呀！但是，注意了，这其实是完全有可能的。还记得当时Bob刚刚查看完整及的帐号信息，基于银行A的cookie并不过期，当出现如上链接出现在src的时候（note that .src is meant to be src），浏览器尝试着按照本地的cookie去加载上面这个URL，而银行A验证了来源请求的cookie是可以的，所以就这样事情就悄悄的发生了。
    \n-------------------------------案例结束---------------------------
    \n
    \nok，看明白了么，这就是CSRF，一句话给他下个定义就是：借你的cookie在你不知道的时候悄悄的做了一些你不愿意做 的事情。恶日期这里有个更要命的是，这个包含上述URL的图片或者链接，并不需要一定是放在银行A的服务器上，相反可以在任一地方，比如blog，公开的 BBS，或者一些群发的Mail中等等，如此多的场合下，这些都有可能存在陷阱。
    \n再看一副图片吧，其说明的正是CSRF的攻击原理。
    \n
    \n
    \n 三、CSRF的预防
    \n看上去很恐怖吧，是的，确实恐怖，意识到恐怖是个好事情，这样会促使你接着往下看如何改进和防止类似的漏洞出现。
    \n总体来说，预防CSRF主要从2个方面入手，分别是：
    \n1、正确使用GET,POST和Cookie；
    \n2、在non-GET请求中使用Security token；
    \n
    \n一般上，大家知道的浏览器发送请求的方式有GET或者POST，但是还有一种比较常用的是Cookie，至于其他的HTTP协议请求方式，你可以google，一般按照W3C的规范：
    \n1、GET常用在查看，列举，展示的时候；
    \n2、POST常用在下达订单，改变一个资源的属性或者做其他一些事情；
    \n
    \nok，我们这里拿Rails按照前面列举的2种预防手段做说明，首先，我们可以在Rails的控制权中（controller）将一些方法（action）限定（verify）为只能使用POST或者GET，例如：
    \n
    \nRuby代码
    \n
    \n    verify :method => :post, :only => [ :transfer ], :redirect_to => { :action => :list }   
    \n
    \n
    \n恩，很好，这样做下限制以后，前面案例中的方法就失效了，因为这里我们限定了transfer必须使用POST来提交请求，当GET请求来的时候并不会被响应。
    \n万事大吉了？NO！因为POST的请求也是可以被构造出来后自动发送的，如何实现，看下面吧，你肯定会吃惊的。
    \n
    \nXML/HTML代码
    \n
    \n    <a .href="http://www.1sters.com/" onclick="var f = document.createElement('form'); f.style.display = 'none'; this.parentNode.appendChild(f); f.method = 'POST'; f.action = 'http://www.example.com/account/destroy f.submit();return false';;">点我试试</a>  
    \n
    \n
    \n是的，这就是一个活生生的例子(.href is meant to be href)，使用link的href或者img的src都可以的，再想想一个Attacher放了一个图片，然后写了一个onmouseover方法，执行上述的那段JS，如下，或者使用AJAX。
    \n
    \nXML/HTML代码
    \n
    \n    <img .src="http://www.harmless.com/img" width="400" height="400" onmouseover="…" />  
    \n    
    \n
    \n
    \n所以，限定为POST后还不是非常的保险，怎么办？不急，我们还有第二步，给non-GET的请求设置 security token，如何实现，在Rails2以后非常简单（也是默认的），我们只需要在environment.rb中添加如下代码：
    \n
    \nRuby代码
    \n
    \n    config.action_controller.session = {  
    \n      :session_key => '_csrf_session',  
    \n      :secret      => 'ae4b43dda38ff78bb50898b2935da76d1e224061ab72a9399d34cea4c6178eee6dae815fff920a20642f27abda83b793da4e9b6cf20c4838805e80abf53e318a'  
    \n    }  
    \n
    \n
    \n然后在application controller中包含如下security token设置：
    \n
    \nRuby代码
    \n
    \n    protect_from_forgery  :secret => '053cef294a333f72c3584311799c69d2'  
    \n
    \n
    \nok，基本上安全了，如果这时POST请求过去，但是security token和session计算出来的secret和服务端的secret匹配不上的话，就会返回一个ActionController::InvalidAuthenticityToken错误，防止该类缺陷的出现。
    \n安全了，也许你要说，那我如果能破解出protect_from_forgery，不进OK了么，按照理论上是，但是实际是破解是基本上不可能的，因为有人曾计算过，暴力破解该串大概需要2的11次方时间，后续我将再写一篇文章详细的介绍，这里不再赘述。
    \n
    \n四、总结
    \n总的来说，CSRF的兴起刚刚开始，网络上肯定会有一股热潮，Railser们一定要注意自己的程序的安全性，CSRF比你我能想到的更有威胁，千万别小瞧了它。

    前面已经说了“与时俱进,使用Git”，用了几天git后，越来越觉得不错，如下说说SVN和Git的主要区别：
    \n
    \n
    Git是分布式SCM，而SVN是基于服务器的，也就是说每个开发者本地都有一套git库，每个人维护自己的版本（或者合并其他人的版本），而SVN是每个人写完代码后都及时的checkin到服务器上，进行合并。
    \n
    \n
    如果上面这段话还不能让你真正了解Git的好处，而不想使用git来替代你的svn的话，那么我再列举几个我认为不错的比较直观的场景：
    \n
    1、可以在本地（离线）就做好版本控制，而不用时刻连网，特别是Soho一族或者喜欢经常到处跑，又喜欢在路上、车上或者马路旁边的小凳子上coding的人；这个时候你可以在自己的Git库上进行版本控制，而不用到处找网络把代码搞到svn上去。
    \n
    2、分布式的SCM更加安全和健壮，有没有想过，如果你的SVN版本服务器挂掉了（硬盘坏了或者网络不可用等等），你会咋样，能修复的好么，一旦修复不好，资料都完蛋了，而Git的分布式SCM，其中的几个节点挂掉影响并不大。
    \n
    3、速度，你如果使用GoogleCode或者其他的SVN服务的话，不知道你是否有呆呆的等待chenkin完成的情况（我是经常有的），而Git，毫无疑问，速度快的多，（就算是使用GitHub也快），究其原因，应该是Git是打包好了上传，而不像SVN单个文件上传。
    \n
    4、版本、分支管理
    \n
    还有啥？想不来了，差不多就这样了，视个人情况而定，但是我认为Git会让你更加满意。
    \n
    但是有人可能会有这样的想法，我本地使用git，然后定时的checkin到SVN上，这样岂不是更好，啊哈，好吧，你还不习惯或者还有其他的特殊情况（比如其他开发者不喜欢git，或者原来的代码在svn上等等），这里看看如何把git和svn结合起来一起使用。
    \n
    1、比较笨的方法
    \n
    同时使用Git和SVN，然后再各自的“忽略”列表里面加加上对方的版本库，比如在svn的忽略列表中加上.git，而同时在git的.gitignore中加上.svn；然后执行各自的命令。
    \n
    2、比较靠谱的方法
    \n
    使用git-svn应该算更加科学和靠谱的方法，安装好git-svn（这个是需要单独安装的）后，就可以使用啦，基本上是这样的：
    \n
    mkdir 1stlog
    \ncd 1stlog && git-svn init http://1stlog.googlecode.com/svn/trunk/

    很早前就说过，我非常喜欢使用GoogleDoc来写技术文章，其好处有很多：
    \n
    \"\"
    \n
    1、编辑、组织、协作、维护方便
    \n
    GoogleDoc的编辑器我非常喜欢，去掉Word中那些我基本上用不上的功能，而只提供需要的功能，这是比较难得可贵的，“不要让用户思考”是一种好的用户体验，而我深信，google在这个方面比盖茨大叔做的更符合我的需求。
    \n
    我可以按照不同的文件夹或者Tag来组织我的文章，可以快速方便的索引和搜索到需要找到的文档。
    \n
    GoogleDoc的协助功能也非常的榜，我经常和其他人一起完成一份文档的编写，这比在本地写一份文档传来传去要方便，合理的多。我们经常一起编写，在意见不一致的地方批注，等待其他人的确认等等。
    \n
    另外，每次修改都有历史版本信息，可以很轻松的找到以前的版本，这点相当的好呀。
    \n
    2、在线存储，更加方便
    \n
    GoogleDoc是在线存储的，按照google和amazon的“云计算”的概念，这应该算云计算的一种了，其强大的云存储能力，我相信比存在我本地或者我自己的服务器上更加安全和可靠，且我可以随时随地的联网更新和查看，而不需要随身拿个U盘带来带去，还要提防丢失U盘的噩梦。
    \n
    另外，这样比直接发布在自己的Blog要可靠的多，谁知道您的blog服务商或者自己的blog服务器会不会那天罢工，或者哪天你的域名失效，或者那天您的数据库崩溃了，还有。。。
    \n
    3、离线功能，锦上添花
    \n
    以前有人说“要是我上不了网，那我岂不是死翘翘了！”，呵呵，现在有了离线功能，可以在本地编辑，然后在有网络的时候再传上去就OK了。
    \n
    4、不一安装，且自动更新，不断完善
    \n
    GoogleDoc还有个好处是，其不用每次修复一个漏洞或者增加一个新功能都要down下来重新安装，他在服务端更新了，我就可以即刻体验，免去一切不必要的麻烦。另外，他的功能还在不断的增加，比如我就很期待一个可以自动给代码着色的功能，那样我写文章里面的代码就可以更加直观了。只是我不知道谁还有和我类似的需求，也没有找到反馈的地方，有人有类似需求的么？帮我一起反馈上去吧 :)
    \n
    相信随着网速的越来越快，所谓的云计算都能得到很好的应用。我现在只有工作的时候写相关文档才被迫使用Word，虽然在家的本本上的Ubuntu下有Openoffice，但是写自己的一些技术文章的时候，我还都是使用GoogleDoc。且可以利用其它的技术（比如GoogleSite）来整合、组织和展示文档。大家可以在IceskYsl@Docs上看到我分享出来的一些技术文档。

    今天在看一篇比较不错的文章“ 从LiveJournal后台发展看大规模网站性能优化方法”，该文章说了其LiveJournal发展过程中的几个阶段，逐渐的扩展和完善架构，从一个真实的环境中看出其架构的基本趋势。文中提到了memcached，原来memcached就诞生于此，很有兴趣的再多了解一些，memcached属于Danga，旗下还有其他几个很著名的东西，比如MogileFS等。
    \nMemcached 是高效、快速的分布式内存对象缓存系统，主要用于加速 WEB 动态应用程序。关于Memcached的安装等，可以参考“PHP & memcached”这篇文章的说明，基本上和其他unix下的程序安装差不多，下载源码、编译等等，不再赘述。
    \n
    其使用非常简单，直接就一个命令，连配置文件都省了，如下：
    \n
    /usr/bin/memcached -d -m 128 -l 192.168.10.1 -p 11211 -u httpd
    \n
    其参数分别代表：
    \n
     
    \n
    \n
    XML/HTML代码
    \n
      \n    
    1. -d 以守护程序（daemon）方式运行 memcached；  
      2. \n    
    2. -m 设置 memcached 可以使用的内存大小，单位为 M；  
      3. \n    
    3. -l 设置监听的 IP 地址，如果是本机的话，通常可以不设置此参数；  
      4. \n    
    4. -p 设置监听的端口，默认为 11211，所以也可以不设置此参数；  
      5. \n    
    5. -u 指定用户，如果当前为 root 的话，需要使用此参数指定用户。  
      6. \n
    \n
    \n
    如果你想了解在Rails中如何使用，请参cai同学翻译的”Ruby on Rails + Memcached“，或者直接去看原文；另外，如果你和我一样比较喜欢Nginx做webserver，你可以看看我写的Nginx在Ubuntu上的一系列文章，马上会加上Memcached的相关内容。

    \n今天在看一篇比较不错的文章“ 从LiveJournal后台发展看大规模网站性能优化方法”，该文章说了其LiveJournal发展过程中的几个阶段，逐渐的扩展和完善架构，从一个真实的环境中看出其架构的基本趋势。文中提到了memcached，原来memcached就诞生于此，很有兴趣的再多了解一些，memcached属于Danga，旗下还有其他几个很著名的东西，比如MogileFS等。
    \nMemcached 是高效、快速的分布式内存对象缓存系统，主要用于加速 WEB 动态应用程序。关于Memcached的安装等，可以参考“PHP & memcached”这篇文章的说明，基本上和其他unix下的程序安装差不多，下载源码、编译等等，不再赘述。
    \n其使用非常简单，直接就一个命令，连配置文件都省了，如下：
    \n/usr/bin/memcached -d -m 128 -l 192.168.10.1 -p 11211 -u httpd
    \n其参数分别代表：
    \n 
    \n
    \nXML/HTML代码
    \n
    \n    -d 以守护程序（daemon）方式运行 memcached；  
    \n    -m 设置 memcached 可以使用的内存大小，单位为 M；  
    \n    -l 设置监听的 IP 地址，如果是本机的话，通常可以不设置此参数；  
    \n    -p 设置监听的端口，默认为 11211，所以也可以不设置此参数；  
    \n    -u 指定用户，如果当前为 root 的话，需要使用此参数指定用户。  
    \n
    \n
    \n如果你想了解在Rails中如何使用，请参cai同学翻译的”Ruby on Rails + Memcached“，或者直接去看原文；另外，如果你和我一样比较喜欢Nginx做webserver，你可以看看我写的Nginx在Ubuntu上的一系列文章，马上会加上Memcached的相关内容。

    当MYSQL成为越来越多的web2站点的选择的DB的时候，当站点越来越大，流量越来越多，用户越来越多的时候，数据库往往第一个成为系统的瓶颈，如何提升DB的性能成为系统成败的关键点，本文只是从自己的认识上说说可以从几个方面提升MYSQL的性能，以及可以采取的扩展方式。但是不会详细的阐述，详细的说明和操作，分析方法以后有时间再仔细分享。
    \n
    一、选择合适的数据库存贮引擎
    \n
    MYSQL支持的引擎很多，例如MyISAM，MEMORY，InnoDB等等类型，每个类型试用的场景是不一样的，恰当的选择存储引擎可以节省你不少时间，详细的介绍你可以参考”第15章：存储引擎和表类型“。
    \n
    二、优化SQL语句
    \n
    不要以为SQL语句关系不大，按照以往的经验，往往几个畸形的SQL就可以拖垮一个DB，决定不是危言耸听，在从系统优化和DB优化及其扩展之前，请仔细检查系统中用到的SQL，先解决SQL可能带来的问题，而经验是，做好这步，就可以解决很多初期的性能问题。
    \n
    三、建立索引
    \n
    这和前面的SQL优化有一定的联系，仔细查看你的SQL语言，尽可能的优化他，然后建立必须的索引，千万不要忽视了索引的威力，我们曾经有过测试，2W条的基本数据，生成页面，没有索引前，推算其全部生成需要的时间是81个小时，而加上索引后，只需要12分钟，多大的性能提升，各位可以自己那计算器粗略的算算。
    \n
    四、建立分区&表空间
    \n
    很多人以为只有Oracle才有表空间，分区这些东西，不想到MYSQL中也有类似的东西吧，尽管这个东西是mysql5才引入的，尽管其还不是很成熟，但是毫无疑问，这是一个好的信号，在我们使用MYSQL的时候就有了更多的方案来提升性能了。
    \n
    分区一般分为水平分区和垂直分区，MYSQL目前只支持水平分区，有RANGE,LIST,HASH,KEY等等分区方式，详细说明以后再说，你可以参考”第18章：分区“，"通过分区（Partition）提升MySQL性能"等文章。
    \n
    表空间的相关话题，可以参考”第17章：MySQL簇“，不在赘述。
    \n
    五、调整MYSQL和系统参数
    \n
    这个方案是伴随着整个性能提升过程的，你的不时的调整参数以得到更好的性能，这个比较复杂，没有啥成文的规定，都是靠经验或者实践得到的。
    \n
    六、集群或者proxy
    \n
    到这里为止，单机的MYSQL基本上可以优化调整的都涉及到了，如果这个时候还是顶不住压力，该考虑水平扩展或者垂直扩展了，垂直扩展比较容易，只要针对单机的性能得到瓶颈的所在，增加CPU或者内存或者换比较强劲的设备就可以很快得到立竿见影的效果。
    \n
    但是垂直扩展能力有限，不可能得到无限级的扩展，风险也比较大，除了垂直扩展，大家选择较多的是水平扩展，也就是通过增加服务器，无限的得到性能的扩展，当然这个里面内容是很多的，如何做到数据库的备份，同步等都是需要考虑和解决的问题，而且还要考虑这么多机器间的数据重复成都等问题；除此之外，还有可能将数据库缓存到memcached或者使用mysql proxy等实现连接池之类的方案，都是需要考虑和抉择的。
    \n
    以上每个分类都是个大的话题，这么一篇文章只是说明了优化的思路和基本流程，其中涉及到很多东西，例如诊断和分析等都是很有技术含量的，我们下次会一个专题一个专题的仔细分析，力求将MYSQL的性能达到尽可能的榜。

    以前说过，我最喜欢的一个跑Rails的方式是Nginx在前面，后端采用mongrel或者thin，采用nginx的原因不在多说，想详细了解 nginx的参考我以前的文章，按照道理来说，这样的方案已经很不错了，如果再加上memcached做cach，应该可以顶住不小的压力了。
    \n但是其当时也说到，Nginx的负载均衡到目前为止还是比较简单的轮训算法，他不会检测后端的mongrel是否压力过大，或者是否已经down下去了，这样就会初选，如果其中的一个mongrel挂掉了，nginx还是会把请求分过去的，这样就存在一个问题。
    \n
    \n于是就有这么一个需求，能不能监控到后端的mongrel的状况，做智能分发呢？啊哈，是的，可以，HAProxy就可以做到这点。先看个改进版的架构。
    \n\"\"
    \nok，比较清晰吧，Nginx接收到请求后，放到RequestQueue中，然后HAProxy从queue中取请求，智能的分发给后端的 App.Server。如此处理的好处就是HAProxy可以判断后端App.Server的负载情况以及是否down机情况，然后做智能分发。
    \n

    以前说过，我最喜欢的一个跑Rails的方式是Nginx在前面，后端采用mongrel或者thin，采用nginx的原因不在多说，想详细了解 nginx的参考我以前的文章，按照道理来说，这样的方案已经很不错了，如果再加上memcached做cach，应该可以顶住不小的压力了。
    \n但是其当时也说到，Nginx的负载均衡到目前为止还是比较简单的轮训算法，他不会检测后端的mongrel是否压力过大，或者是否已经down下去了，这样就会初选，如果其中的一个mongrel挂掉了，nginx还是会把请求分过去的，这样就存在一个问题。
    \n
    \n于是就有这么一个需求，能不能监控到后端的mongrel的状况，做智能分发呢？啊哈，是的，可以，HAProxy就可以做到这点。先看个改进版的架构。
    \n
    \nok，比较清晰吧，Nginx接收到请求后，放到RequestQueue中，然后HAProxy从queue中取请求，智能的分发给后端的 App.Server。如此处理的好处就是HAProxy可以判断后端App.Server的负载情况以及是否down机情况，然后做智能分发。
    \nOK,比较清晰了，我们再把Memcached加上，再加上智能判断一台服务器Down掉的情况，我再画个图片，如下：

    WillPaginate这个插件很棒，以至于其取代了Rails中原有的Paginate方法，虽然看上其很简单，其实还是有不少技巧的，本篇用来记录我遇到的或者使用到的一些tips。
    \n
    \n1.直接使用paginate
    \n这个比较简单，也是使用的最多的，如下：
    \n
    \n
    Ruby代码
    \n
      \n    
    1. def self.get_all_items_in_catelog( catelog_id,page,per_page="10")  
      2. \n    
    2.   paginate :per_page => per_page, :page => page,  
      3. \n    
    3.     :conditions =>["catelog_id = ? and caiji > 0",catelog_id],  
      4. \n    
    4.     :order => 'created_at DESC ,updated_at  DESC'  
      5. \n    
    5. end  
      \n    
      6. \n
    \n
    \n
     2.使用Model.paginate_by_sql
    \n有的时候，你需要的SQL用Rails拼的时候有些不方便，这个时候可以考虑使用paginate_by_sql来实现，这个没啥好说的，你需要什么样的SQL直接写就可以了，例如：
    \n  #排行榜列表
    \n
    \n
    Ruby代码
    \n
      \n    
    1. def self.get_all_items_in_rank(rank_id, page,per_page="10")  
      2. \n    
    2.     Book.paginate_by_sql ["SELECT DISTINCT `books`.* FROM `books` LEFT OUTER JOIN `ranksorts` 
      \n    
      3. \n    
    3. ON (`books`.`prodid` = `ranksorts`.`prodid`) LEFT OUTER JOIN `ranks`  
      \n    
      4. \n    
    4. ON (`ranks`.`id` = `ranksorts`.`rank_id`) WHERE (ranks.id = ?) 
      \n    
      5. \n    
    5. ORDER BY books.updated_at DESC,books.created_at DESC", rank_id],  
      6. \n    
    6.       :page => page, :per_page => per_page  
      7. \n    
    7. end  
      8. \n
    \n

    还有其他的一些小技巧，慢慢添加，你如果有类似的技巧，期待您的分享。。

    Q. How do I install Ubuntu ftp service or server?
    \n
    A. Ubuntu Linux comes with various ftp servers to setup FTP service such as:
    \n=> proftpd - Versatile, virtual-hosting FTP daemon
    \n
    => vsftpd - The Very Secure FTP Daemon
    \n
    => ftpd - FTP server
    \n
    => wu-ftpd - powerful and widely used FTP server
    \n
    => wzdftpd - A portable, modular, small and efficient ftp server
    \n
    => pure-ftpd - Pure-FTPd FTP server
    \n
    其中vsftpd相当优秀，其配置简单方便，且非常安全，如下是其主页上的说明：
    \n
    vsftpd is the Very Secure File Transfer Protocol Daemon. The server can be launched via a super-server such as inetd or xinetd. Alternatively, vsftpd can be launched in standalone mode, in which case vsftpd itself will listen on the network.
    \n
    => Default ftp port : 21
    \n=> Default configuration file : /etc/vsftpd.conf
    \n
    Q：如何安装vsftpd
    \n
    很简单，即可搞，如下：
    \n
    \n### Step # 1: Install vsftpd\n
    Type apt-get command to install vsftpd
    \n````$ sudo apt-get install vsftpd```
    \nOutput:
    \n
    \n``Password:

    Adding system user `ftp' with uid 106...
    Adding new user `ftp' (106) with group `nogroup'.
    Not creating home directory `/home/ftp'.
     * Starting FTP server: vsftpd```\n
    \n### Step # 2: Configure /etc/vsftpd.conf\n
    The default vsftpd configuration file is /etc/vsftpd.conf. You need to edit this file using text editor such as vi:
    \n````$ sudo vi /etc/vsftpd.conf```
    \n
    Add the following line (uncomment line) to the vsftpd configuration file:
    \n````local_enable=YES```
    \nAbove config directive will allow local users to log in via ftp
    \n
    If you would like to allow users to upload file, add the following to the file:
    \n````write_enable=YES```
    \n
    For security you may restrict local users to their home directories. Add the following to the file:
    \n````chroot_local_user=YES```
    \n
    Save and close the file.
    \n### Step # 3: Restart vsftpd\n
    To restart vsftpd type the command :
    \n````$ sudo /etc/init.d/vsftpd restart```
    \nOutput:
    \n``* Stopping FTP server: vsftpd                                                                                       [ ok ]
     * Starting FTP server: vsftpd                                                                                       [ ok ]

    add following rules to your iptables script. Assuming that default
    incoming policy is drop. If protocol is TCP and destination port is 21
    (ftp):

    ````iptables -A INPUT -p tcp -m tcp --dport 21 -j ACCEPT```

    See - How do I open open ftp port 21 using iptables for more information.```\n
    There are a large number of other configuration options available for vsftpd that can be used to fine tune ftp server. Read vsftpd.conf man page by typing following command:
    \n````$ man vsftpd.conf```

    Step # 2: Configure /etc/vsftpd.conf
    \n\n
    The default vsftpd configuration file is /etc/vsftpd.conf. You need to edit this file using text editor such as vi:
    \n$ sudo vi /etc/vsftpd.conf```</strong></p>
    \n<p>Add the following line (uncomment line) to the vsftpd configuration file:<br />
    \n<strong>    local_enable=YES</strong><br />
    \nAbove config directive will allow local users to log in via ftp</p>
    \n<p>If you would like to allow users to upload file, add the following to the file:<br />
    \n<strong>    write_enable=YES</strong></p>
    \n<p>For security you may restrict local users to their home directories. Add the following to the file:<br />
    \n<strong>    chroot_local_user=YES`
    \nSave and close the file.
    \n\n
    Step # 3: Restart vsftpd
    \n\n
    To restart vsftpd type the command :
    \n$ sudo /etc/init.d/vsftpd restart```</strong><br />
    \nOutput:</p>

    \n1、Sphinx，是俄罗斯的Andrew Aksyonoff 开发的，被人叫做“狮身人面”，关于其高效的介绍，你可以参考《JavaEye3.0开发手记之三 － 狮身人面》，其性能出色，和架构清晰，学习成本很低，且其和数据库结合的很棒。其他相关介绍可以参考“coreseek对Sphinx的就介绍”，也可以参考其发布的《Coreseek 全文检索服务器 2.0 (Sphinx 0.9.8)参考手册》，其Coreseek就是基于Sphinx的一个全文搜索服务器。
    \n2、libmmseg，就是前面说的中文分词程序，当前最新版本是0.73，采用C++开发，同时支持Linux平台和Windows平 台，切分速度大约在300K/s（PM-1.2G），libmmseg从0.7.2版本开始，作者提供了ruby调用的接口，所以我们可以直接在ruby 程序里面调用libmmseg进行分词，相当方便。
    \n3、Ultrasphinx，是一个Rails插件，Rails开发人员可以使用它来很方便地调用Sphinx的功能。其他类似的插件有acts_as_sphinx，使用其可以很方便的在Rails中整合Sphinx。
    \n\n
    以上三个的安全不是很复杂，推荐是在Unix上，请参考《Rails程序员Sphinx中文全文检索安装指南》，这个文章就是基于以上三个组件的安装和使用说明。我会在近期发布出一些笔记和文档，以帮助需要的朋友更好的实现自己的全文检索。

    总的来看，有两个方式来实现对WML的支持，单独支持和整合支持，下面详细的说。
    \n\n
    一、按照一般方式支持
    \n\n
    这个方式和做PC WEB方式是一样的，有个单独的controller或者action，指定特有的layout和页面模板，而这些模板中采用WML语言编写，在请求到来的时候，按照URL中特有的特征字符（比如二级域名）或者Http Head中的标识转向Wap的action，进而显示。详细的步骤基本上是这样的：

    \n      @headers["Content-Type"] = “text/vnd.wap.wml; charset=iso-8859-1″  
    \n    end  
    \n
    \n
    \n2、添加一个WAP的全局布局模板app/views/layouts/wap.rhtm
    \n
    \nXML/HTML代码
    \n
    \n    <?xml version=”1.0″?>

    \n    <p align=”center”>  
    \n    <%= @content_for_layout %>  
    \n    </p>  
    \n    </card>  
    \n    </wml>  
    \n
    \n
    \n3、在我的controller中（index）中增加一个action用来响应WAP请求。
    \n
    \nRuby代码
    \n
    \n    def wap  
    \n      @title = "San Francisco Sailing Weather"  
    \n      render(:layout => "wml")  
    \n    end  
    \n
    \n
    \n4、添加相应的view模板app/views/index/wap.rhtml
    \n
    \nXML/HTML代码
    \n
    \n    <%= link_to 'NOAA Marine Forecast', { :controller => '/marine/forecast', :action => 'wap' } %><br/>  
    \n    <%= link_to 'Wind Readings', { :controller => '/marine/wind', :action => 'wap' } %><br/>  
    \n    <%= link_to 'Current Predictions', { :controller => '/marine/tide', :action => 'wap' } %>  
    \n
    \n
    \n

    \n\n
    在Rails2以后，Rails支持多种格式的输出，比如Html，RSS，JS等，当然你还可以定制自己的格式，比如我们这里说的WML，Iphone等，使用起来更简单、自然。
    \n\n
    1、添加MIME格式支持
    \n\n
    在config/environment.rb中增加MIME的格式支持，方式如下：
    \n
    \nRuby代码
    \n
    \n    Mime::Type.register "text/vnd.wap.wml", :wml  
    \n
    \n
    \n
    \n2、判断请求类型
    \n<div class="codeText">

    \n</ol>
    \n</div>
    \n<pre style="font-size: 90%;">
    \n<strong>3、添加相应的view代码</strong>比较简单，就是写XML或者WML模板<strong>show.wml.erb</strong>
    \n
    \nXML/HTML代码
    \n
    \n    xml.instruct! :xml, :version => "1.0"  
    \n    xml.wml "xml:lang" => "en-gb" do  
    \n      xml.card :title => "My title here" do  
    \n        xml.p "Something interesting here"  
    \n        xml.p "Something else interesting here."  
    \n      end  
    \n    end  
    \n
    \n
    \n
    \n4、添加输出类型支持
    \n<div class="codeText">
    \n<div class="codeHead">Ruby代码</div>
    \n<ol class="dp-rb" start="1">
    \n    <li class="alt"><span><span class="keyword">def</span><span> index  </span></span></li>

    很明显，Pandora受限后，其他做音乐的会有一个比较好的机会来迅速填补这个空缺，强占一定的用户，但问题是，谁有能力顶起这片天呢？让我们看看在中国的情况。
    \n\n
    中国的在线音乐网站非常多，但是形式都普遍的很单一，主要有三种形式：
    \n\n
    1、大部分都是首页上横七竖八的堆一堆排行榜，点了直接就听歌，其代表者有一听，九天等。
    \n\n
    2、另外一个代表者是Baidu MP3下载，虽然人气不错，但是其损害的是唱片公司或者是艺人的利益，一直以来都是官司缠身。
    \n\n
    3、还有一种是新兴的web2模式的音乐网站，有yobo.com，8box等等网站，其加入社区和互动，yobo甚至还有点Pandora的味道，主推音乐DNA。就目前我用到的，我最看好的还是YOBO，虽然最近他们也遇到一些问题。
    \n\n
    YOBO成立于2006年12月，从1.0到2.0到3.0，和现在正在开发的4.0版本中，在一步步的完善，用户口碑也越来越好。其上的电台和频道功能相当不错，很多定制化的东西可以很容易的找到需要的歌曲，如果你习惯Pandora的智能推荐模式，那么你可以设置让其自动推荐，虽然有的时候结果可能并不能让你满意，但是，请注意，YOBO还不到2岁，他还在不断的完善。
    \n\n
    另外就是最近老是遇到服务器不能及时响应的事情，就我感觉，不排除有人使坏，还是流量真的大的顶不住。
    \n\n
    对了，还有一个last.fm，其现在推出的中版主打中国市场，但是其和其他舶来品差不多，有点水土不服，加上速度一直被人诟病，中文歌曲质量不高等，暂时还不是很看好。

    大家都知道，在Rails中比较常见的做法是使用“auto increment”的id做为主键，虽然很便捷，但是也存在以下问题：
    \n\n
    1）敏感信息泄漏 --比如注册用户数，发表文章数等，内行一眼就看出你系统的规模；
    \n\n
    2）分布式DB存在冲突 --一个DB不够了，需要多个DB的时候，可能会存在ID冲突的情况；
    \n\n
    3）旧数据库影响  --导入、导出的时候可能存在一些问题（rake db:schema:dump）
    \n\n
    由于这些问题都是很关键的，所以很有必要做一些改变，思路很简单，使用UUID做主键，可以保证主键的唯一性（类似12f186e6-687e-11ad-843e-001b632783f1，全世界唯一），又能隐藏敏感信息，且实现很简单，如下：

    在Linux下面部署应用的时候，有时候会遇上Socket/File: Can’t open so many files的问题，其实Linux是有文件句柄限制的，而且默认不是很高，一般都是1024，作为一台生产服务器，其实很容易就达到这个数量，因此我们需 要把这个值改大一些。
    \n\n
    我们可以用ulimit -a来查看所有限制值，我只关心文件句柄数量的问题
    \nopen files (-n) 1024
    \n这个就是限制数量 ，其指的是当前用户准备要运行的程序的限制。比较推荐的修改方法是：
    \n\n
    正确的做法，应该是修改/etc/security/limits.conf

    \r\n
    \r\n深入分析
    \r\n今天，另外一个负责主机维护的同事发现其/var/log/messages.x中有如下信息：
    \r\n    \r\n
    Jul 30 17:36:15 www login(pam_unix)[11819]: session opened for user siteview by (uid=0)
    \r\nJul 30 17:36:15 www  -- siteview[11819]: LOGIN ON pts/0 BY siteview FROM 192.168.168.42
    \r\nJul 30 17:36:15 www login(pam_unix)[11819]: session closed for user siteview
    \r\nJul 30 17:47:17 www syslogd: /var/log/secure: No space left on device
    \r\nJul 30 19:11:58 www PAM-securetty[1611]: Couldn't open /etc/securetty
    \r\n 经过查找发现其原因是内核中开启的审核子系统LauS (Linux Auditing System)写的日志太多，把/var空间占了，再次登陆的时候，由于无法写日志导致挂在那里，出现假死现象。
    \r\n
    \r\n解决方法：
    \r\n定位到问题以后，就可以想办法解决了，目前可行的办法由四种，分别如下：
    \r\n1、定期手工删除/var/log/audit.d下的日志文件\r\n
    #删除7天前的
    \r\nfind ./ -mtime +7 -type f -exec rm {} \\;
    \r\n2、配置crob自动删除或者备份\r\n
    SEVEN_DAYS_OLD=`/usr/locale/ebin/date '+%d' --date '7 days ago'`
    \r\nif [ -f /var/log/audit/bin/bin.${SEVEN_DAYS_OLD} ]
    \r\nthen
    \r\nrm /var/log/audit/bin.${SEVEN_DAYS_OLD}
    \r\nfi
    \r\n
    \r\n3、修改/etc/audit/audit.conf配置文件
    \r\n可以通过修改audit.conf来配置，让其自动处理
    \r\n1）修改为自动删除的：
    \r\n    notify = \"/usr/sbin/audbin -S /var/log/audit.d/save.%u -C -T 20% -N 'rm -f %f'\";
    \r\n[The notify line as above should (according to the docs) remove old 'save' files when the filesystem comes within 20% of full (change the figure after -T to specify how close to full you want to start deleting old files).]
    \r\n
    \r\n    2）修改为自动备份的：（/backup 是另外您想保存数据的分区）\r\n

    现象描述
    \n项目中有台服务器，其操作系统为RHEL 3 ，主要用途是实验室环境以及和第三方系统的FTP服务器，最近出现经常出现“假死”的情况，具体表现是Ping的通，但是ssh、ftp、telnet等都无法登陆，从lan console上看服务器运行正常。每次都是远程重启暂时解决问题。
    \n
    \n深入分析
    \n今天，另外一个负责主机维护的同事发现其/var/log/messages.x中有如下信息：
    \n
    \nJul 30 17:36:15 www login(pam_unix)[11819]: session opened for user siteview by (uid=0)
    \nJul 30 17:36:15 www  -- siteview[11819]: LOGIN ON pts/0 BY siteview FROM 192.168.168.42
    \nJul 30 17:36:15 www login(pam_unix)[11819]: session closed for user siteview
    \nJul 30 17:47:17 www syslogd: /var/log/secure: No space left on device
    \nJul 30 19:11:58 www PAM-securetty[1611]: Couldn't open /etc/securetty
    \n 经过查找发现其原因是内核中开启的审核子系统LauS (Linux Auditing System)写的日志太多，把/var空间占了，再次登陆的时候，由于无法写日志导致挂在那里，出现假死现象。
    \n
    \n解决方法：
    \n定位到问题以后，就可以想办法解决了，目前可行的办法由四种，分别如下：
    \n1、定期手工删除/var/log/audit.d下的日志文件
    \n#删除7天前的
    \nfind ./ -mtime +7 -type f -exec rm {} \\;
    \n2、配置crob自动删除或者备份
    \nSEVEN_DAYS_OLD=/usr/locale/ebin/date '+%d' --date '7 days ago'
    \nif [ -f /var/log/audit/bin/bin.${SEVEN_DAYS_OLD} ]
    \nthen
    \nrm /var/log/audit/bin.${SEVEN_DAYS_OLD}
    \nfi
    \n
    \n3、修改/etc/audit/audit.conf配置文件
    \n可以通过修改audit.conf来配置，让其自动处理
    \n1）修改为自动删除的：
    \nnotify = "/usr/sbin/audbin -S /var/log/audit.d/save.%u -C -T 20% -N 'rm -f %f'";
    \n[The notify line as above should (according to the docs) remove old 'save' files when the filesystem comes within 20% of full (change the figure after -T to specify how close to full you want to start deleting old files).]
    \n
    \n2）修改为自动备份的：（/backup 是另外您想保存数据的分区）
    \nnotify = "/usr/sbin/audbin -S /var/log/audit.d/save.%u -C -T 20% -N 'mv %f /backup'"; 
    \n
    \n4、禁用audtid服务
    \n如 果您不需要审核信息，禁用audtid服务 ("chkconfig --del auditd"),系统性能会有所提高. 如果想要彻底禁用内核中的audit，可以删除 /dev/audit文件，重新启动。以后可以通过在grub.conf 里kernel行最后加入audit=1来启用。

    SimpleConfig looks nice, but it definitely has a few differences from Configatron. The first big difference is that SimpleConfig is limited to use with Rails. Configatron can be used with any framework, any application, and any script. Configatron also seems a bit easier to use. There are no mixins needed to use it. The configatron method lives in Kernel, which means it’s available everywhere, no ‘configuration’ needed. \":)\" Different strokes, eh? There are a few other configuration systems out there, I always encourage people to check out the options before they decide on a piece of software to use.
    \r\n其实我们自己也可以写，只是没有必要再搞一套，功能上来说，上述这两个足够了，下面简单的看看Configatron 的用法：\r\n1、安装\r\n$ sudo gem install configatron\r\n2、定义（支持namespace）\r\n
    \r\n
    Ruby代码
    \r\n
      \r\n\t
    1. configatron do |config|

      16. \r\n\t
    16. end  
      17. \r\n
    \r\n
    \r\n3、使用\r\n
    \r\n
    Ruby代码
    \r\n
      \r\n\t
    1. configatron.mems.iceskysl.email # => \"iceskysl@1sters.com\"  
      2. \r\n\t
    2. configatron.mems.shine.blog_url # => \"http://shine.1sters.com\"  
      3. \r\n\t
    3. configatron.website_url # => \"http://www.1sters.com\"  
      4. \r\n
    \r\n
    \r\n4、重写\r\n
    \r\n
    Ruby代码
    \r\n
      \r\n\t
    1. configatron do |config|  
      2. \r\n\t
    2.   config.website_url = \"http://www.1sters.com/index\"

    搞Java的人应该很习惯把一些配置（数据库连接、个性化配置等）写到配置文件中，一般会使用XML或者TXT文件中，在启动的时候读取配置，初始化等等。
    \nRails中也可以实现类似的功能，虽然Rails提倡“零配置”，但有的时候开发一个系统，比如Blog系统等还是需要一些个性化的配置，我们原来的实现方式是：增加一个配置文件，启动的时候读取，并保存为全局变量，用的时候直接使用。也很方便。
    \n其实还可以使用插件或者gem来做，Configatron就是这么一个gem，另外还有一个插件版的SimpleConfig，两者还是有些不同的，按照Configatron 作者的说法，其不同点在于：
    \nSimpleConfig looks nice, but it definitely has a few differences from Configatron. The first big difference is that SimpleConfig is limited to use with Rails. Configatron can be used with any framework, any application, and any script. Configatron also seems a bit easier to use. There are no mixins needed to use it. The configatron method lives in Kernel, which means it’s available everywhere, no ‘configuration’ needed.  Different strokes, eh? There are a few other configuration systems out there, I always encourage people to check out the options before they decide on a piece of software to use.
    \n其实我们自己也可以写，只是没有必要再搞一套，功能上来说，上述这两个足够了，下面简单的看看Configatron 的用法：
    \n1、安装
    \n$ sudo gem install configatron
    \n2、定义（支持namespace）
    \n
    \nRuby代码
    \n
    \n    configatron do |config|  
    \n      config.website_url = "http://www.1sters.com"  
    \n      config.namespace(:mems) do |mem|  
    \n        email.namespace(:iceskysl) do |iceskysl|  
    \n          iceskysl.email = "iceskysl@1sters.com"  
    \n          pop.blog_url = "http://iceskysl.1sters.com"  
    \n          # etc ...  
    \n        end  
    \n        email.namespace(:shine) do |shine|  
    \n          smtp.email = "shine@1sters.com"  
    \n          smtp.blog_url = "http://shine.1sters.com"  
    \n          # etc ...  
    \n        end  
    \n      end  
    \n      # etc...  
    \n    end  
    \n
    \n
    \n3、使用
    \n
    \nRuby代码
    \n
    \n    configatron.mems.iceskysl.email # => "iceskysl@1sters.com"  
    \n    configatron.mems.shine.blog_url # => "http://shine.1sters.com"  
    \n    configatron.website_url # => "http://www.1sters.com"  
    \n
    \n
    \n4、重写
    \n
    \nRuby代码
    \n
    \n    configatron do |config|  
    \n      config.website_url = "http://www.1sters.com/index"  
    \n    end  
    \n

    Rails丰富的插件真是强大，幻想着把各个功能都做出插件，以后开发系统就像搭积木一样堆积就好啦，呵呵。
    \n开发个Rails插件其实不难，或者说很简单，流程基本如下：
    \n1、生成骨架
    \n在Rails的script下有个generate，可以直接生成骨架，执行：
    \n\n
    ruby script/generate plugin foo
    \n\n
    就会在$RAILS_ROOT/vendor/plugins下生成一个foo目录，如下：
    \n
    \nRuby代码
    \n
    \n    /1stlog$ruby script/generate plugin foo  
    \n          create  vendor/plugins/foo/lib  
    \n          create  vendor/plugins/foo/tasks  
    \n          create  vendor/plugins/foo/test  
    \n          create  vendor/plugins/foo/README  
    \n          create  vendor/plugins/foo/MIT-LICENSE  
    \n          create  vendor/plugins/foo/Rakefile  
    \n          create  vendor/plugins/foo/init.rb  
    \n          create  vendor/plugins/foo/install.rb  
    \n          create  vendor/plugins/foo/uninstall.rb  
    \n          create  vendor/plugins/foo/lib/foo.rb  
    \n          create  vendor/plugins/foo/tasks/foo_tasks.rake  
    \n          create  vendor/plugins/foo/test/foo_test.rb  
    \n
    \n
    \n2、编写相关代码
    \n在lib/foo.rb 下编写你的插件代码即可。
    \n
    \nRuby代码
    \n
    \n    module Foo  
    \n      def say_hello name  
    \n        "hello \#{name}"  
    \n      end  
    \n    end  
    \n
    \n
    \n3、混入到core中去
    \n在init.rb中编写混入代码即可。
    \n
    \nRuby代码
    \n
    \n    require 'foo'    
    \n    ActionController::Base.send :include, Foo
    \n

    \n我住的地方有两台电脑，通过一台无线路由，经猫用ADSL上网，一直以来都用的好好的，前不久搬家到7楼（以前住3楼），河隔壁合用一个ADSL，一共四台电脑（两个本本，两个台式机），本本通过无线连接，两个台式机通过有线连接到路由器，用的挺好。

    \n\n
    初步分析：
    \n1、猫的DSL灯不亮，说明信号没进来，看来猫坏了，联系电信的来换了个猫，DSL灯亮了，可以通过本本连接有线上网，猫的问题解除；
    \n2、接下来按照以前的方式走路由器，发现路由器的WAN还是不亮，然后本本有线到路由器上，无法上网，怀疑路由器挂了，幸好买了不久，拿回去换了一个，路由器问题解决；
    \n3、换了路由器后，本本有线连接可以使用，上网正常，但是突然发现两台台式机均无法连接到路由器，还是现实“网线被拔出”的红叉叉，电脑的网卡灯也不亮。
    \n\n
    深入分析：
    \n1、调换本本和台式机的网线，还是老样子，看来不是网线的问题；
    \n2、重装了台式机的网卡驱动，还是老样子，看来不是驱动的问题；
    \n3、两台台式机症状类似，看来是和打雷有关，google了一下，果然，很多人遇到过这样的问题（我还真是第一次遇到），貌似说打雷的时候出现电涌现象，导致网卡损坏。甚至有的会导致主板、显示器都坏掉。
    \n\n
    解决问题：
    \n1、先可以试试是否是主版屏蔽了网卡，在BIOS里面重新加载下板载网卡，是否可以；
    \n2、如果不行，就只能换网卡了，如果用PCI的，得在BIOS里面把板载网卡禁用掉；如果使用USB的，则可以直接使用。
    \n\n
    注意事项：
    \n1、打雷、闪电的时候关闭计算机，拔掉电源，拔掉ADSL线，关掉猫、路由器的电源；
    \n2、晚上睡前，拔掉ADSL，关闭计算机电源。

    \n-n sets the maximum total # of connections (2000)
    \n-m limits the usable amount of memory (in MB)
    \n-N sets the default, per-proxy maximum # of connections (2000)
    \n-p writes pids of all children to this file
    \n-de disables epoll() usage even when available
    \n-ds disables speculative epoll() usage even when available
    \n-dp disables poll() usage even when available
    \n-sf/-st [pid ]* finishes/terminates old pids. Must be last arguments.

    对于Rails开发者来说，总觉得一大堆的CSS代码非常碍眼，写起来也不是很优雅，有没有更优雅的方法，毫无疑问，是有的。
    \n\n
    先看一段正常的CSS代码：
    \n
    \nCSS代码
    \n
    \n    div.article div.title {  
    \n      font-weight: bold;  
    \n    }  
    \n    div.article div.title a.author {  
    \n      padding-left: 12px;  
    \n      background: url('user.png') no-repeat left;  
    \n    }  
    \n    div.article div.text {  
    \n      border: 1px solid #EEE;  
    \n      background: #FEF;  
    \n    }  
    \n
    \n
    \n再看一段有那么点不一样的代码：
    \n
    \nCSS代码
    \n
    \n    div.article {  
    \n      div.title {  
    \n        font-weight: bold;  
    \n          
    \n        a.author {  
    \n          padding-left: 12px;  
    \n          background: url('user.png') no-repeat left;  
    \n        }  
    \n      }  
    \n      div.text {  
    \n        border: 1px solid #EEE;  
    \n        background: #FEF;  
    \n      }  
    \n    }  
    \n
    \n
    \n有啥不一样了么？是否有点发懵呢，呵呵，下面这个写法更清晰和优雅，不是么！但是这样写的话，我们的浏览器是不认识的，怎么办，可以采用第三方的类库来转换即可。现在看到的可以做这个事情的有FrontCompiler和css_dryer，除了这个功能外，还有其他的功能，例如FrontCompiler还可以合并多个JS/CSS文件，代码如下：
    \n
    \nRuby代码
    \n
    \n    @c = FrontCompiler.new  
    \n    @library_code = @c.compact_files(%w{  
    \n      src/lib.js  
    \n      src/lib/something.js  
    \n      src/lib/another.js  
    \n    })  
    \n
    \n
    \n其他的功能请参考其各自的主页。

    歌词如下：
    \n\n
    「稻 香」
    \n作词：周杰伦 作曲：周杰伦
    \n\n
    对这个世界如果你有太多的抱怨
    \n跌倒了就不敢继续往前走
    \n为什么人要这么的脆弱 堕落
    \n请你打开电视看看
    \n多少人为生命在努力勇敢的走下去
    \n我们是不是该知足
    \n珍惜一切 就算没有拥有
    \n\n
    还记得你说家是唯一的城堡 随着稻香河流继续奔跑
    \n微微笑 小时候的梦我知道
    \n不要哭让萤火虫带着你逃跑 乡间的歌谣永远的依靠
    \n回家吧 回到最初的美好
    \n\n
    不要这么容易就想放弃 就像我说的
    \n追不到的梦想 换个梦不就得了
    \n为自己的人生鲜艳上色 先把爱涂上喜欢的颜色
    \n笑一个吧 功成名就不是目的
    \n让自己快乐快乐这才叫做意义
    \n童年的纸飞机 现在终于飞回我手里
    \n\n
    所谓的那快乐 赤脚在田里追蜻蜓追到累了
    \n偷摘水果被蜜蜂给叮到怕了 谁在偷笑呢
    \n我靠着稻草人吹着风唱着歌睡着了
    \n哦 哦 午后吉它在虫鸣中更清脆
    \n哦 哦 阳光洒在路上就不怕心碎
    \n珍惜一切 就算没有拥有
    \n\n

    昨天有幸认识了terry，看到其blog上有篇文章”消费者对音乐内容Metadata的需求“，其中写到”音乐Metadata是所有数字音乐服务的根基，它的完备性也将直接影响服务的可扩展性。“，最基础也是应用最普遍的是”2.音乐目录元数据，例如歌曲名、专辑名、词曲作者等直接描述音乐作品的信息。这些信息通常会直接体现在各种数字音乐服务上。“。其给出一份消费者对metadata需求的调查研究，如下：

    \n今天突然来了兴趣，分析一首歌曲，找到其对应的metadata信息，经过资料查找和分析，目前已经基本完成，主要是读取MP3文件的ID3信息（ID3v1，ID3v1.1以及ID3v2），ID3v1的信息比较好读取，下面会给出一段ruby代码，ID3v2比较复杂，也有比较成熟的开源库，这里就不详细说了，我写在GoogleDoc里了，有感兴趣的可以自行研究或者找我要。

    \r\n
    XML/HTML代码
    \r\n
      \r\n\t
    1. General options:  
      2. \r\n\t
    2.   
      3. \r\n\t
    3. -h or --help  
      4. \r\n\t
    4.     Print quick or full usage details respectively.  
      5. \r\n\t
    5. -r or --recursive  
      6. \r\n\t
    6.     Search directory arguments recursively for files to convert.  
      7. \r\n\t
    7. -d or --delete  
      8. \r\n\t
    8.     delete input files after successful conversion. May not be safe yet!!!  
      9. \r\n\t
    9. -v or --verbose  
      10. \r\n\t
    10.     makes sneetchalizer more chatty.  
      11. \r\n\t
    11. -s or --show-output  
      12. \r\n\t
    12.     shows output from conversion tool.  
      13. \r\n\t
    13. -p or --pretend  
      14. \r\n\t
    14.     don't convert anything. sneetchalizer will go through the motions and print out the commands it would run. Useful for preview- ing a complex command line to ensure it does what you intend. You should interpret this option's output with a grain of salt. For example, if you include the '--sanitize' option, the files will not really be renamed when using --pretend, and as such the command's output will not reflect that the filenames would be changed during an actual run.  
      15. \r\n\t
    15. -t or --terminate  
      16. \r\n\t
    16.     terminate sneetchalizer options. This is useful if you have to convert '--coolDir' or '-groovySong.mp3'. This is the only option whose order on the command line is significant.  
      17. \r\n\t
    17. -D ARG or --out-directory=ARG  
      18. \r\n\t
    18.     write all outfiles to a directory argument. This is useful if you want to (re)encode files directly to a mounted portable device.  
      19. \r\n\t
    19. --strict and --pedantic  
      20. \r\n\t
    20.     many errors that sneetchalizer may encounter are recoverable, such as specifying a directory as argument that contains no files to convert, or conversion failures in general. By default the script will print an error message and move on to the next file. If you use '--strict' then sneetchalizer will bail out at the first sign of trouble except for tag errors. With '--pedantic' the script will stop even on tag errors.   
      21. \r\n\t
    21. --stasis  
      22. \r\n\t
    22.     Preserve timestamp (mtime) of original file.  
      23. \r\n\t
    23. --threads [N]  
      24. \r\n\t
    24.     Experimental. Use threads to create concurrent jobs. This option takes an optional integer argument which represents the number of threads to launch. The default is two. Preliminary tests suggest there is little advantage (and even diminishing returns) when setting this number greater than the number of cores/CPUs you have. Due to the asychronous nature of threads the --verbose and --show-output flags will be silently disabled and most screen output is supressed.   
      25. \r\n\t
    25. --sanitize  
      26. \r\n\t
    26.     Removes ,, ;, :, ', \", %, @, #, and ` from filenames and tags.  
      27. \r\n\t
    27. -n [FORMAT] or --rename[=FORMAT]  
      28. \r\n\t
    28.     rename all outfiles (and temporary wavs) according to FORMAT. FORMAT is a string with special designators to be pulled from the file tags. The following options are available:  
      29. \r\n\t

      46. \r\n\t
    46.   
      47. \r\n\t
    47. quality and bitrate are passed directly to lame or oggenc depending on mp3 or ogg output format respectively. Both tools can handle either a bitrate or quality argument, so it is important to understand what values are valid for the underlying tool in your specific use case. faac will accept a bitrate argument, but not a quality argument. These options will be silently ignored for any output formats other than mp3, ogg or m4a. Make sure you know what you are doing if you decide to use both in one run, and read each tools manpage for valid values. If these options are omitted the tools builtin defaults are used (-q3 for oggenc and -q5 for lame).

      51. \r\n\t
    51.   
      52. \r\n\t
    52. this option allows you to pass a compression argument to flac and mac. See 'flac --help' and/or 'mac --help' if you don't know what this means.

      60. \r\n\t
    60.   
      61. \r\n\t
    61. Valid output formats are: \"aac\", \"aif\", \"aifc\", \"aiff\", \"aiffc\", \"ape\", \"au\", \"cdr\", \"cdda\", \"copy\", \"flac\", \"m4a\", \"m4b\", \"mpc\", \"mp4\", \"mpp\", \"mp3\", \"mp2\", \"ofr\", \"ofs\", \"ogg\", \"snd\", \"spx\", \"tta\", \"wav\", \"wv\". Valid input formats are all of the above plus \"wma\". You can specify multiple input formats using a comma: 'mp3,m4a,wma'. Input format is only neccesary when passing directory arguments, as file arguments are handled by context (read: file extension). The \"copy\" output option copies files directly, bypassing decoding/encoding steps (useful in conjunction with --rename).

    \r\n另外，你可以运行sneetchalizer -h看到简要的使用说明，也可以使用sneetchalizer --help看到详细的使用信息。\r\n\r\n3、使用示例\r\n\r\n如下简要的写几个使用的示例：\r\n
    \r\n
    使用示例：
    \r\n
      \r\n\t
    1. $ sneetchalizer song.mp3  
      2. \r\n\t
    2.   
      3. \r\n\t
    3. The most simple possible example, creates 'song.wav'.  
      4. \r\n\t
    4.   
      5. \r\n\t
    5. $ sneetchalizer --out=ogg --in=flac -q5 /some/music/dir  
      6. \r\n\t
    6.   
      7. \r\n\t
    7. This example converts every flac file in '/some/music/dir' to ogg format at quality 5.  
      8. \r\n\t
    8.   
      9. \r\n\t
    9. $ sneetchalizer -d --out=mp3 --in=ogg,m4a,wma -b 160 .  
      10. \r\n\t
    10.   
      11. \r\n\t
    11. Converts every ogg, m4a, and wma file in the current directory to a 160 kbps constant bitrate mp3 file. The original files are deleted.  
      12. \r\n\t
    12.   
      13. \r\n\t
    13. $ sneetchalizer --out=mp3 --out-optionhook=\"--preset extreme\" /some/wavs  
      14. \r\n\t
    14.   
      15. \r\n\t
    15. Here we encode every wav in '/some/wavs' to mp3 format passing '--preset extreme' directly to lame.  
      16. \r\n\t
    16.   
      17. \r\n\t
    17. $ sneetchalizer --in=ogg --out=ogg --quality=1 norvegianWood.ogg /some/more/oggs  
      18. \r\n\t
    18.   
      19. \r\n\t
    19. Using the same --in and --out format allows us to resample/encode the file at a different bitrate or quality. Note that this will overwrite the original file so only do this on a copy, or use '-D' to write files to another directory.  
      20. \r\n\t
    20.   
      21. \r\n\t
    21. $ sneetchalizer --in=ogg --out=m4a -D /mnt/ipod/ /some/oggs  
      22. \r\n\t
    22.   
      23. \r\n\t
    23. Here we re-encode some ogg files to m4a format and write them to our mounted iPod.   
      24. \r\n
    \r\n
    \r\n4、注意事项\r\n\r\n本脚本只是粘合剂，其他的tool还是需要另外安装的。\r\n\r\n其他信息请参考其主页说明,如果您有这个方面的问题或经验，欢迎和我讨论。\r\n\r\n\r\n\r\n\r\n ", "created_at"=>2008-10-09 02:49:27 UTC, "updated_at"=>2012-06-24 15:47:03 UTC, "body_html"=>"
    前几天写了“采用Ruby提取MP3的metadata信息”后，就在寻找成熟的Ruby代码做差不多的事情，今天找到一个sneetchalizer，仔细的看了下，非常强大。
    \n\n\n
    sneetchalizer其实只是个粘合剂，因为在*unix下，audio格式转换的lib已经非常丰富和成熟，例如lame,gogo,bladeenc,mplayer等等就非常好用；另外，关于audio的tag信息和metadata信息的提取也有比较成熟的lib了，类似id3lib-ruby library,wmainfo-rb library,ruby-ogginfo library等等。而sneetchalizer只是把这些tools粘合起来。
    \n\n
    其支持的格式有:'aac' 'aif' 'aifc' 'aiff' 'aiffc' 'ape' 'au' 'caf' 'cdda' 'cdr' 'copy' 'fap' 'flac' 'gsm''ircam' 'm4a' 'm4b' 'mat' 'mat4' 'mat5' 'mp2' 'mp3' 'mp4' 'mpc' 'mpp' 'nist' 'ofr''ofs' 'ogg' 'paf' 'pvf' 'raw' 'sd2' 'sds' 'sf' 'snd' 'spx' 'svx' 'tta' 'voc''vox' 'w64' 'wav' 'wma' 'wv' 'xi'
    \n\n
    使用sneetchalizer可以实现audio文件的格式转换和tag信息提取和写入，详细使用方法参考其主页上说明，下面简要的说说起安装方法和使用参数：
    \n\n
    1、安装方法
    \n\n
    直接下载其gz包，sneetchalizer-0.9.0是现在的最新版本。下载解包后可以看到：
    \n
    \nManifest:
    \n
    \n    README                - You're reading it now.  
    \n    LICENSE               - A copy of the GPL, under which sneetchalizer is released.  
    \n    CHANGES               - sneetchalizer's cvs/svn commit log.  
    \n    sneetchalizer         - The script itself.  
    \n    sneetchalizer.1       - The manpage for sneetchalizer.  
    \n    sneetchalizer.desktop - A KDE service menu for converting with Konqueror.  
    \n    install.rb            - A quick and dirty script to install the sneetchalizer.  
    \n
    \n
    \n如果有root权限，可以直接运行install.rb，其会将sneetchalizer拷贝到/usr/bin下，将sneetchalizer.1拷贝到/usr/share/man/man1下。
    \n\n
    2、参数解释
    \n\n
    不翻译了，都挺简单明了的，如下：
    \n
    \nXML/HTML代码
    \n
    \n    General options:  
    \n

    \n        Search directory arguments recursively for files to convert.  
    \n    -d or --delete  
    \n        delete input files after successful conversion. May not be safe yet!!!  
    \n    -v or --verbose  
    \n        makes sneetchalizer more chatty.  
    \n    -s or --show-output  
    \n        shows output from conversion tool.  
    \n    -p or --pretend  
    \n        don't convert anything. sneetchalizer will go through the motions and print out the commands it would run. Useful for preview- ing a complex command line to ensure it does what you intend. You should interpret this option's output with a grain of salt. For example, if you include the '--sanitize' option, the files will not really be renamed when using --pretend, and as such the command's output will not reflect that the filenames would be changed during an actual run.  
    \n    -t or --terminate  
    \n        terminate sneetchalizer options. This is useful if you have to convert '--coolDir' or '-groovySong.mp3'. This is the only option whose order on the command line is significant.  
    \n    -D ARG or --out-directory=ARG  
    \n        write all outfiles to a directory argument. This is useful if you want to (re)encode files directly to a mounted portable device.  
    \n    --strict and --pedantic  
    \n        many errors that sneetchalizer may encounter are recoverable, such as specifying a directory as argument that contains no files to convert, or conversion failures in general. By default the script will print an error message and move on to the next file. If you use '--strict' then sneetchalizer will bail out at the first sign of trouble except for tag errors. With '--pedantic' the script will stop even on tag errors.   
    \n    --stasis  
    \n        Preserve timestamp (mtime) of original file.  
    \n    --threads [N]  
    \n        Experimental. Use threads to create concurrent jobs. This option takes an optional integer argument which represents the number of threads to launch. The default is two. Preliminary tests suggest there is little advantage (and even diminishing returns) when setting this number greater than the number of cores/CPUs you have. Due to the asychronous nature of threads the --verbose and --show-output flags will be silently disabled and most screen output is supressed.   
    \n    --sanitize  
    \n        Removes ,, ;, :, ', ", %, @, #, and ` from filenames and tags.  
    \n    -n [FORMAT] or --rename[=FORMAT]  
    \n        rename all outfiles (and temporary wavs) according to FORMAT. FORMAT is a string with special designators to be pulled from the file tags. The following options are available:  
    \n      
    \n            * %t Song title  
    \n            * %b Album title  
    \n            * %n Track number  
    \n            * %a Artist name  
    \n            * %y Year  
    \n            * %g Genre  
    \n            * %c Comment field  
    \n      
    \n        Directories may be created with this command, as in "%b/%n - %t". The default value of FORMAT is "%n %t".   
    \n      
    \n    Bitrate/Quality/Compression options:  
    \n      
    \n    -b or --bitrate  
    \n        mp3/ogg/m4a bitrate.  
    \n    -q or --quality  
    \n        mp3/ogg quality.  
    \n      
    \n    quality and bitrate are passed directly to lame or oggenc depending on mp3 or ogg output format respectively. Both tools can handle either a bitrate or quality argument, so it is important to understand what values are valid for the underlying tool in your specific use case. faac will accept a bitrate argument, but not a quality argument. These options will be silently ignored for any output formats other than mp3, ogg or m4a. Make sure you know what you are doing if you decide to use both in one run, and read each tools manpage for valid values. If these options are omitted the tools builtin defaults are used (-q3 for oggenc and -q5 for lame).  
    \n      
    \n    -c or --compression  
    \n        flac/mac compression level.  
    \n      
    \n    this option allows you to pass a compression argument to flac and mac. See 'flac --help' and/or 'mac --help' if you don't know what this means.  
    \n      
    \n    Format Options:  
    \n      
    \n    --out=format  
    \n        output format. Default is wav.  
    \n    --in=format[,format..]  
    \n        input format(s). Default is wav.  
    \n      
    \n    Valid output formats are: "aac", "aif", "aifc", "aiff", "aiffc", "ape", "au", "cdr", "cdda", "copy", "flac", "m4a", "m4b", "mpc", "mp4", "mpp", "mp3", "mp2", "ofr", "ofs", "ogg", "snd", "spx", "tta", "wav", "wv". Valid input formats are all of the above plus "wma". You can specify multiple input formats using a comma: 'mp3,m4a,wma'. Input format is only neccesary when passing directory arguments, as file arguments are handled by context (read: file extension). The "copy" output option copies files directly, bypassing decoding/encoding steps (useful in conjunction with --rename).  
    \n      
    \n    Tagging Options:  
    \n      
    \n    --tt or --title  
    \n        Set 'title' tag.  
    \n    --ta or --artist  
    \n        Set 'artist' tag.  
    \n    --tl or --album  
    \n        Set 'album' tag.  
    \n    --ty or --year  
    \n        Set 'year' tag.  
    \n    --tc or --comment  
    \n        Set 'comment' tag.  
    \n    --tg or --genre  
    \n        Set 'genre' tag.  
    \n    --tn or --trackn  
    \n        Set 'track number' tag.  
    \n      
    \n    The short and long versions are different in an important way: Using the long version will clobber any existing tags. The short version will only set the tag if the existing tag has no value. Note that these tags will be placed in _every_ outfile during the run.  
    \n      
    \n    Alternative Encoder/Decoder Options:  
    \n      
    \n    --gogo  
    \n        use gogo to encode mp3 files.  
    \n    --bladeenc  
    \n        use bladeenc to encode mp3 files.  
    \n      
    \n    The default is still 'lame'. If 'lame' is not found, the script will search for one of these two encoders regardless if these options are passed or not.  
    \n      
    \n    Special Options:  
    \n      
    \n    --in-optionhook=ARG  
    \n        add ARG to infile conversion command. Possibly dangerous!  
    \n    --out-optionhook=ARG  
    \n        add ARG to outfile conversion command. Possibly dangerous!

    3、使用示例
    \n\n
    如下简要的写几个使用的示例：
    \n
    \n使用示例：
    \n
    \n    $ sneetchalizer song.mp3  
    \n      
    \n    The most simple possible example, creates 'song.wav'.  
    \n      
    \n    $ sneetchalizer --out=ogg --in=flac -q5 /some/music/dir  
    \n      
    \n    This example converts every flac file in '/some/music/dir' to ogg format at quality 5.  
    \n      
    \n    $ sneetchalizer -d --out=mp3 --in=ogg,m4a,wma -b 160 .  
    \n      
    \n    Converts every ogg, m4a, and wma file in the current directory to a 160 kbps constant bitrate mp3 file. The original files are deleted.  
    \n      
    \n    $ sneetchalizer --out=mp3 --out-optionhook="--preset extreme" /some/wavs  
    \n      
    \n    Here we encode every wav in '/some/wavs' to mp3 format passing '--preset extreme' directly to lame.  
    \n      
    \n    $ sneetchalizer --in=ogg --out=ogg --quality=1 norvegianWood.ogg /some/more/oggs  
    \n      
    \n    Using the same --in and --out format allows us to resample/encode the file at a different bitrate or quality. Note that this will overwrite the original file so only do this on a copy, or use '-D' to write files to another directory.  
    \n      
    \n    $ sneetchalizer --in=ogg --out=m4a -D /mnt/ipod/ /some/oggs  
    \n      
    \n    Here we re-encode some ogg files to m4a format and write them to our mounted iPod.   
    \n
    \n

    Ruby可以很方便的解析XML格式的文档，目前用的比较多的lib主要有三个，分别是：REXML, Hpricot, libxml-ruby，如下选取两个XML文档，分别使用这三个lib解析，感受下各自的速度和易用性。
    \n一、原料
    \n
    \n    posts.xml – Uses xml element for object (post) and xml attributes for object attributes
    \n    timeline.xml – Uses xml element for object (status) and child xml elements for attributes
    \n
    \n二、解析过程
    \n1、REXML
    \n\n
    Pros: In the standard library
    \nCons: Slow, I don’t like the name

    \n      end  
    \n      # pp posts

    \n      # pp statuses  
    \n    }  
    \n
    \n
    \n<code class="ruby"><strong>2、Hpricot</strong><strong>Pros:</strong> Cool name, created by _why, faster than <span class="caps">REXML</span>, also does <span class="caps">HTML</span>, creative <span class="caps">API</span><strong>Cons:</strong> Not as fast as libxml-ruby, more of an <span class="caps">HTML</span> parser linguistically (ie: uses innerHTML instead of text or content, etc.)``

    \n
    \n
    \n3、libxml-ruby 
    \n\n
    Pros: Blistering fast
    \nCons: Hpricot has cooler name, REXML and Hpricot both feel easier to use out of the box

    然后拖着行李（一个箱子，一个背包，一本电脑包，还有一个袋子装了一双球鞋和运动鞋）换乘10号线到国贸，找到SOHO小区，找到落脚点。
    \n\n
    一路下来还算顺利。

    晚上同事带去吃饺子，北京的饺子真大呀，比深圳的三个还大，赞。

    接下来就要尽快进入状态了，还有几个朋友要见，还有些事情要处理，终于来到北京了，一个新起点。

    \n7.  定义在它上面的约束没有任何作用，约束是由基本表控制的，例如两个基本表中存在着同样的一个Key值，那么在MERGE表中会有两个一样的Key值。

    需要时不时的看看memcached的状态，其自身只提供了get、set等方法啊我们需要使用其提供的方法遍历一下其缓存的内容，其原理请参考《如何对memcache的数据(key-value)进行遍历操作 》和《贴一段遍历memcached缓存对象的小脚本》。
    \n
    memcache的stats命令包括：
    \n
    \n1.        stats  
    \n2.        stats reset  
    \n3.        stats malloc  
    \n4.        stats maps

    \n8.        stats cachedump slab_id limit_num  
    \n9.        stats detail [on|off|dump] 
    \n
    \n
    说说其实现遍历的原理：
    \n
      \n    
    1. telnet到192.168.15.225（局域网测试机器）的memcache服务器;
      2. \n    
    2. 执行stats items命令，可以看到出现 很多的items行。
      3. \n    
    3. 执行stats cachedump 3 0命令。这里的3表示上面图中items后面的数字，0标示显示全部的数据，如果是1就标示只显示1条。 
      \n    下图为执行后的结果，item后面的字符串为key
      4. \n    
    4.  通过上面列出的key我们就可以遍历所有的数据了，下面我们取出某一条数据，key为Uc!uLh的数据。

    做web开发的都知道用户上传大文件（比如照片，MP3等）需求有如下难题：
    \n1、文件的存储 -这个不难，买个NAS，规划好目录结构，在mount下就可以了；
    \n
    2、上传速度  --这个问题受限与用户带宽、服务器带宽以及服务器的处理时间，用户带宽无法控制，服务器端的带宽需要监控下，只要未达到上限，也不存在问题；还存在的一个问题就是服务器的处理。
    \n
    3、服务端处理 --这个处理包括请求的接收，文件的校验、存放等，如果文件比较大，在Rails中或许就存在一些问题，请求到web服务器，如Nginx后，达到其设定的缓存大小就发给后端的Rails，这样就会占一个链接直到处理完毕，而后端的thin或者其他的app服务器一共就那么点并发，导致上传比较频繁的时候，压力很大。
    \n
    一个比较不错的解决方案是使用Nginx的upload module，其用C编写的，其处理完上传后，将文件存在在设定的临时目录中，然后将文件路径和你设定的一次哦参数透传给后端的Rails；再用Rails处理一些基本的信息，返回处理结果就可以了，如此一个请求的处理时间也就10ms的样子，开2个thin就可以承受很大的压力了。
    \n
    这个实现还是挺简单，需要注意的upload module非默认的Nginx的module，需要另外下载和编译进去，另外还要注意文件存放的临时文件名可能出现同名的现象，在存取的时候需要留意下。

    说句题外话，Erlang这个名字我很有亲切感，要是熟悉我的人肯定不会奇怪，呵呵。
    \n
    Erlang概述
    \n
    \nErlang不但是一种编程语言，而且它具有比编程语言更加贴近操作系统的一些特性：并发线程、作业调度、内存管理、分布式、网络化等。据说使用Erlang编写的Yaws Web服务器，其并发性能是apache的15倍！（这个没啥好炫耀的吧～）
    \n
    \n这个Erlang初始开源版本包含了Erlang的实现，同时它也是用于构建分布式高可用性系统的Ericsson中间件的最大组成部分。
    \n
    \nErlang具有以下特性：
    \n
    \n并发性 - Erlang具有超强的轻量级进程，这种进程对内存的需求是动态变化的，并且它没有共享内存和通过异步消息传送的通讯。Erlang支持超大量级的并发线程，并且不需要操作系统具有并发机制。
    \n
    \n分布式 - Erlang被设计用于运行在分布式环境下。一个Erlang虚拟机被成为Erlang节点。一个分布式Erlang系统是多个Erlang节点组成的网络（通常每个处理器被作为一个节点）。一个Erlang节点能够创建运行在其它节点上的并行线程，而其它节点可以使用其它操作系统。线程依赖不同节点之间的通讯，这完全和它依赖于单一节点一样。
    \n
    \n健壮性 - Erlang具有多种基本的错误检测能力，它们能够用于构建容错系统。例如，进程能够监控其它进程的状态和活动，甚至这些进程是在其它节点上执行。在分布式系统中的线程能够配置为在其它节点故障的情况下自动进行故障恢复，并在故障节点恢复时自动迁移回到恢复节点。
    \n
    \n软实时性 - Erlang支持可编程的“软”实时系统，这种系统需要反应时间在毫秒级。而在这种系统中，长时间的垃圾收集（garbage collection）延迟是无法接受的，因此Erlang使用了递增式垃圾收集技术。
    \n
    \n热代码升级 - 一些系统不能够由于软件维护而停止运行。Erlang允许程序代码在运行系统中被修改。旧代码能被逐步淘汰而后被新代码替换。在此过渡期间，新旧代码是共存的。这也使得安装bug补丁、在运行系统上升级而不干扰系统操作成为了可能。
    \n
    \n递增式代码装载 - 用户能够控制代码如何被装载的细节。在嵌入式系统中，所有代码通常是在启动时就被完全装载。而在开发系统中，代码是按需装载的，甚至在系统运行时被装载的。如果测试到了未覆盖的bug，那么只有具有bug的代码需要被替换。
    \n
    \n外部接口 - Erlang进程与外部世界之间的通讯使用和在Erlang进程之间相同的消息传送机制。这种机制被用于和操作系统通讯、与其它语言编写的程序交互。如果出于高效率的需要，这种机制的一个特殊版本也允许例如C程序这样的代码直接链接到Erlang运行时系统中来。

    A:you'll need to brush up on your trigonometry, and first compute the Haversine function (this is the standard way of doing it). In order to use the Java trig functions, you'll have to first convert all your angles from degrees to radians. 
    \nGiven two longitude/latitude pairs, and the earth's average radius (assume 6356.78km for your calculations), 
    \nyou can calculate the distance between the 2 points via this Java code: 
    \n
    \n     \tdouble EarthRad = 6356.78;\t// in km ! 
    \n// first convert to radians... 
    \ndouble geo1_lat = geo1.getLatitude()*java.lang.Math.PI/360; 
    \ndouble geo1_lng = geo1.getLongitude()*java.lang.Math.PI/360; 
    \ndouble geo2_lat = geo2.getLatitude()*java.lang.Math.PI/360; 
    \ndouble geo2_lng = geo2.getLongitude()*java.lang.Math.PI/360; 
    \n
    \ndouble deltaLat = java.lang.Math.abs(java.lang.Math.abs(geo2_lat) - java.lang.Math.abs(geo1_lat)); 
    \ndouble deltaLng = java.lang.Math.abs(java.lang.Math.abs(geo2_lng) - java.lang.Math.abs(geo1_lng)); 
    \n
    \ndouble dist = 2*EarthRad*java.lang.Math.asin(java.lang.Math.sqrt(haversine(deltaLat) 
    \n+ java.lang.Math.cos(pair1_lat) 
    \n*java.lang.Math.cos(pair1_lng)*haversine(deltaLng))); 
    \n
    \nWhere "dist" now contains the distance between along the earth's surface. 
    \nYou can find the Haversine function trig equation by Googling it, then construct a method that returns the appropriate value.
    \n
    Computing the speed is straightforward: you know your sampling frequency, and you now know the distance between the most recent two points, so, employee speed = distance / sampling interval

    在Android中使用GoogleMap非常方便，但是有些小技巧或者注意事项你必须牢记，否则调试半天你也不会找到啥线索，浪费时间不说，更让你狂抓，以下技巧都是我在实际项目中遇到的，不断更新和维护，如果你有类似技巧，欢迎分享：
    \n
    （以下技巧是基于SDK 1.0的）
    \n
    一、申请Apikey，并放在正确的位置
    \n
    这个应该都知道，但是是申请得到的key放哪里很多人不知道，可以放在
    \n
    1、XML布局文件中
    \n
    <view android:id="@+id/mv"
    \n   class="com.google.android.maps.MapView"
    \n   android:layout_width="fill_parent"
    \n   android:layout_height="fill_parent"
    \n   android:layout_weight="1" 
    \n   android:apiKey="01Yu9W3X3vbpYT3x33chPXXX7U1Z6jy8WYZXNFA" 
    \n   />
    \n
    2、java中
    \n
            mMapView = new MapView(this, "01Yu9W3X3vbpYT3x33chPxxx7U1Z6jy8WYZXNFA");
    \n
    二、记得导入uses-library 
    \n
     由于1.0版本的修改，使得map包不再是默认的了，使用的时候需要在manifest中的application节点下加入
    \n
    <uses-library android:name="com.google.android.maps" /> 
    \n
    \n
    否则，你将遇到可恶的“java.lang.NoClassDefFoundError: ”，切记！
    \n
    三、需要给予一定的权限
    \n
    因为要使用GoogleMAP的service，所以需要
    \n<uses-permission android:name="android.permission.INTERNET"></uses-permission>
    \n
    如果需要GPS等应用，还需要
    \n
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
    \n
    四、Activity需要继承自MapActivity
    \n
    类似如下代码；
    \n
    package com.iceskysl.showmap;
    \n
    \nimport com.google.android.maps.MapActivity;
    \n
    \nimport android.os.Bundle;
    \n
    \npublic class ShowMap extends MapActivity {
    \n    /** Called when the activity is first created. */
    \n    @Override
    \n    public void onCreate(Bundle savedInstanceState) {
    \n        super.onCreate(savedInstanceState);
    \n        setContentView(R.layout.main);
    \n    }
    \n
    \n    @Override
    \n    protected boolean isRouteDisplayed() {
    \n        // TODO Auto-generated method stub
    \n        return false;
    \n    }

    1. def URLDecode(str)

    在一些API接口传递参数的时候，需要对URL做一些编码，有人写了两个脚本，如下：
    \n
    \n
    \nRuby代码
    \n
    \n    def URLDecode(str)  
    \n       str.gsub!(/%[a-fA-F0-9]{2}/) { |x| x = x[1..2].hex.chr }  
    \n    end  
    \n       
    \n    def URLEncode(str)  
    \n       str.gsub!(/[^\\w$&-+.,\\/:;=?@]/) { |x| x = format("%%%x", x[0]) }  
    \n    end  
    \n
    \n
    \n其实不需要这么麻烦，在Ruby中提供了现成的函数，比如CGI::escape, CGI::inescape, CGI::escapeHTML, CGI::inescapeHTML，CGI::unescape()等，详细的可以看：http://www.ruby-doc.org/core/classes/CGI.html

    Garry Tan, cofounder of Posterous, lists 12 lessons for scaling that apply to more than just Rails,and i mark some word below.
    \n
    \n
  • Use cloud storage for static files. --S3,I do not care it 's fine in china.
    • \n
  • Use HTTP Cache Control to tell the browser what it can cache.  --this is true,etag is great.
    • \n
  • Use Sphinx for text search.  --sometimes,you do have others chose.
    • \n
  • Use InnoDB for more crash resistant and faster writes.  --maybe it's right.
    • \n
  • Don't use textbook Rails ActiveRecord objects. Use New Relic to find exactly what is slow in your system. --yep
    • \n
  • Use memcache later so you find your database bottlenecks now. --this is very important.
    • \n
  • Use mongrel proctitle to find your slow queries. You are only as fast as your slowest queries. -maybe mongrel is not only chose,think about thin,ok?
    • \n
  • Use asynchronous job queuing to do work in parallel.  --yes,but sometimes crontab is enough.
    • \n
  • Use monitoring so you'll know when your site went down and why. --that's it,just do it.
    • \n
  • Learn by reading the source code, fixing problems, and submitting them back to the community.  --very userfull when you got some strange questions..
    • \n
  • Use new plugins. Old plugins can't be trusted. --and check chang histroy carefully.
    • \n
  • Use new information. Old information can't be trusted.  --and what's this?

    \n1.DYNAMICALLY LOADING CONFIG FILES INTO AN ALREADY RUNNING GOD
    \n
    \n
    God allows you to load or reload configurations into an already running instance. There are a few things to consider when doing this:
    \n
      \n    
    • Existng Watches with the same name``` as the incoming Watches will be overidden by the new config.
      • \n    
    • All paths must be either absolute or relative to the path from which god was started.
      • \n
    \n
    To load a config into a running god, issue the following command:
    \n
    $ sudo god load path/to/config.god
    # god load /data/www/api/config/config_thin_api.god```\n
    Config files that are loaded dynamically can contain anything that a normal config file contains, however, global options such as God.pid_file_directory``` blocks will be ignored (and produce a warning in the logs).

    wow，千万级的，看来够大，这个没啥用，先备份下数据文件，然后truncate掉
    \n
    mysql> truncate table  rails_logs_081023;
    \n

    \n
    \n
    出错了，这边表貌似被MERGE用了，查了一下，果然是被rails_logs这个表MERGE着用了，那我直接truncate这个rails_logs试试看。
    \n
    mysql> truncate table  rails_logs;
    \n
    ERROR 1 (HY000): Can't create/write to file './iceskysl_beta_log/rails_logs.MRG' (Errcode: 17)
    \n
    \n
    呀，还是出错，文件不可写？Errcode: 17
    \n
    查下资料，原来：
    \n
    System error: 17 = File exists
    \n
    \n
    这咋回事，再查资料，原来.MRG是创建MERGE表的时候创建的，已经存在了。
    \n
    \n
    那就先把这个MERGE表干掉，再创建：
    \n
    先看下这个表是咋定义的：
    \n
    mysql>  show create table rails_logs;
    \n
    \n
    记录下SQL，接着drop掉。
    \n
    mysql> DROP  table rails_logs;
    \n
    Query OK, 0 rows affected (0.36 sec)
    \n
    \n
    再truncate我的目标表
    \n
    mysql> truncate table  rails_logs_081023;
    \n
    Query OK, 0 rows affected (4.22 sec)
    \n
    \n
    \n
    够快的，11042292条数据4S搞定，接着再创建下这个MERGE表，执行下上面记录的SQL就好了。
    \n
    \n
    最后确认下这表没啥问题：
    \n
    \n
    mysql> select count(id) from rails_logs;
    \n
    +-----------+
    \n
    | count(id) |

    \n
    +-----------+
    \n
    1 row in set (0.00 sec)
    \n
    \n
    OK，搞定，空间有了，天下太平了。

    \n
    \n
    问题：有一个拥有1亿条数据的表，只需要保留其中的5条，其他删除，如何做？
    \n
    这就需要用truncate table来搞定了，如下：
    \n
    select 5条数据 into #临时表 from 1亿条数据的牛X表
    \n
    truncate table 1亿条数据的牛X表
    \n
    --让它牛X，不到10毫秒干掉它。
    \n
    insert 1亿条数据的牛X表 select * from #临时表
    \n
    drop table #临时表

    在项目里用了memcached和cache_fu，其默认的 get_cache(id)还是非常方便的，但是对于另外一个用的比较多的find_by_xx这样的，貌似没看到有现成的方法可以使用。

    \n\n
    This is for a large system with memory = 512M where the system runs mainly

    MySQL.
    \n\n
    You can copy this file to
    \n\n
    /etc/my.cnf to set global options,
    \n\n
    mysql-data-dir/my.cnf to set server-specific options (in this

    installation this directory is /var/lib/mysql) or
    \n\n
    ~/.my.cnf to set user-specific options.
    \n\n
    In this file, you can use all long options that a program supports.
    \n\n
    If you want to know which options a program supports, run the program
    \n\n
    with the "--help" option.
    \n\n
    The following options will be passed to all MySQL clients
    \n\n
    [client]

    Mozilla/Firefox and Safari 3 users should see a nicely rounded box, with a nicely rounded border.
    \nThe code for this example above is actually quite simple:
    \n
    \nThese different corners can also each be handled on their own, Mozilla has other names for the feature than the spec says it should have though, as it has f.i. -moz-border-radius-topright as opposed to -webkit-border-top-right-radius:
    \n\n
    Mozilla/Firefox and Safari 3 users should see a box with a rounded left upper corner.
    \nMozilla/Firefox and Safari 3 users should see a box with a rounded right upper corner.
    \nMozilla/Firefox and Safari 3 users should see a box with a rounded left lower corner.
    \nMozilla/Firefox and Safari 3 users should see a box with a rounded right lower corner.
    \nThese are handled by / should be handled by:
    \n\n
    `-moz-border-radius-topleft / -webkit-border-top-left-radius
    \n-moz-border-radius-topright / -webkit-border-top-right-radius
    \n-moz-border-radius-bottomleft / -webkit-border-bottom-left-radius

    \n\n
    那么应该怎样来配置成我喜欢的颜色呢？下面我们就来详细说一些这些配置。
    \n\n
    ~/.bash_profile是bash shell中当前登录用户的配置文件。bash是“终端”中默认的shell。
    \n\n
    alias ls=”ls -G”是给”ls -G”起了一个别名，当执行ls时，就相当于执行了ls -G。
    \n\n
    CLICOLOR是用来设置是否进行颜色的显示。CLI是Command Line Interface的缩写。
    \nLSCOLORS是用来设置当CLICOLOR被启用后，各种文件类型的颜色。LSCOLORS的值中每两个字母为一组，分别设置某个文件类型的文字颜色和背景颜色。LSCOLORS中一共11组颜色设置，按照先后顺序，分别对以下的文件类型进行设置：
    \n\n
    directory
    \nsymbolic link
    \nsocket
    \npipe
    \nexecutable
    \nblock special
    \ncharacter special
    \nexecutable with setuid bit set
    \nexecutable with setgid bit set
    \ndirectory writable to others, with sticky bit
    \ndirectory writable to others, without sticky bit
    \nLSCOLORS中，字母代表的颜色如下：
    \n\n
    a 黑色
    \nb 红色
    \nc 绿色
    \nd 棕色
    \ne 蓝色
    \nf 洋红色
    \ng 青色
    \nh 浅灰色
    \nA 黑色粗体
    \nB 红色粗体
    \nC 绿色粗体
    \nD 棕色粗体
    \nE 蓝色粗体
    \nF 洋红色粗体
    \nG 青色粗体
    \nH 浅灰色粗体
    \nx 系统默认颜色
    \n所以，如果我们想把目录显示成红色，就可以把LSCOLORS设置为bxfxaxdxcxegedabagacad就可以了

    现就相关事宜申明如下：
    \n一、我开发的所有程序都没有侵犯到用户的隐私。\n\n在这个应用中，申请的全部权限为：\n
    <uses-permission android:name=\"android.permission.INTERNET\" />
    \n
    <uses-permission android:name=\"android.permission.ACCESS_NETWORK_STATE\" />
    \n
    <uses-permission android:name=\"android.permission.WRITE_EXTERNAL_STORAGE\" />
    \n
    <uses-permission android:name=\"android.permission.SET_WALLPAPER\" />
    \n
    <uses-permission android:name=\"android.permission.READ_PHONE_STATE\" />
    \n
    <uses-permission android:name=\"android.permission.ACCESS_COARSE_LOCATION\" />
    \n懂点Android技术的都知道，这些权限都是为了让该软件的功能，能够正常工作所必须的权限（连接网络，获取网络状态，下载壁纸时读写SD卡，设置壁纸，读取手机状态）和Admob的广告精准推送所需要的权限（位置信息，读取手机状态）。\n至于获取用户浏览历史记录、短信、语音邮件密码的这些明显侵犯用户隐私的行为，完全是子虚乌有。一方面并没要申请相关的权限；另一方面我还真不知道怎样获取这些敏感信息。另外，admob的精准广告服务中可能是会针对用户的地理位置等信息推送更准确的广告服务。\n关于这款应用能获取的设备标识号是用来区分设备的唯一性，免去用户注册的麻烦，而能给用户提供收藏图片的功能；而诸如获取手机屏幕大小是为了能够智能适配合适的图片。在这些设备信息中，请问哪一条会侵犯到用户的隐私。\n另外说我可以获取浏览历史信息，这简直就是个天大的笑话。如果懂一点程序的就会知道，要获取浏览器信息必须在程序里申请com.android.browser.permission.READ_HISTORY_BOOKMARKS权限。我的程序完全没有获取到权限，怎么能够获取到历史信息，真是笑话！！！\n\n二、Android手机的权限管理，在任何没有刷过第三方rom的手机上是很严格的。\n Android手机的权限管理，在任何没有刷过第三方rom的手机上是很严格的，在没有相关权限的情况下，要获取那些信息，是完全不可能的。就算是被刷过Rom的手机，也只有具有该ROM制作人的加密签名的程序，才能完成一些不安全的操作。\n我所需要的权限在用户安装的时候会很明确的告诉用户，下面我就给大家展示一下我应用申请的权限和另外一个著名的壁纸的应用background和一款管理短信的应用申请的权限。\n\n我的软件需要的权限：\n\"\"\n\n看看background（另外一款壁纸的应用）申请的权限：\n\"\"\n\nHandcent SMS申请的权限：\n\n\"\"\n\n短信有短信的权限，联系人有联系人的权限，我都没要申请，请问我如何获取相关的信息。\n\n三、应用主要面向外国用户，但绝对没有获取那些高敏感度的隐私信息！\n\n该应用主要面向外国用户（国内由于网络原因无法正常使用），连接服务器端能够获取到精确适配终端的图片，这是一款非常有用，也深受用户喜爱的应用。它确实拥有数量众多（几百万）的用户，但绝对没有获取那些高敏感度的隐私信息！我每天都收到很多用户的反馈邮件告诉我这个软件多么棒，给他们带来多少乐趣！\n\n四、我本人始终与业界同仁一道，希望建立诚实守信、和谐共生的Android产业生态系统。\n\n随着Android开放性操作平台手机的广泛使用，其应用软件开发市场正呈现蓬勃发展景象。对于提醒用户警惕来自手机上的威胁，我本人向来都是强烈支持的！本人一直始终与业界同仁一道，一直为共建诚实守信、和谐共生的Android产业生态系统而努力，将力量专注于用户需求和技术创新，创造更被用户喜欢的软解，并致力于推动手机应用软件产业持续健康发展。\n\n在此，本人郑重申明，该应用没有获取任何诸如“浏览历史记录，短信，语音邮件密码等”这种高敏感度的信息，并和国外的原作者取得联系，让其修正自己的言论并发布公开道歉，同时对于这种不负责任的言论和评价观点，对我及与我相关的应用进行不负责任的报道造成的影响给予补偿，我将保留追究其法律责任的权利。\n\nps：\n\n如果您有其他的疑问或者问题，欢迎你在我sina微博客（http://t.sina.com.cn/iceskysl）或者sohu微博（http://t.sohu.com/iceskysl）给我沟通！\n

    今天在GoogleTalk上朋友发来消息，说有人撰写文章指出我以前开发的一款更换手机壁纸的应用（嵌入了admob和google的广告）中存在偷窃用户隐私数据行为时，我简直不敢相信这是真的；当看到新闻的详细内容时，我更是被震惊了。以下是那段转载文章的原话：
    \n\n
    “拉斯维加斯黑帽大会上，Lookout 的安全人员指出，一个伪装成Android手机壁纸应用的偷窃个人信息程序已经被下载了百万次，它会收集您的个人资料，并将其发送到一个来自中国深圳的神秘网站imnet.us中。安全人员(Kevin MaHaffey)估计这款程序是由正常的壁纸应用修改而来，黑客将其上传到Android Market，希望装饰自己手机的用户因此而中招。泄漏的数据包括浏览历史记录，短信，手机的SIM卡号码，用户识别号，语音邮件，甚至是密码，他警告称每个人都应该警惕来自手机上的威胁。”
    \n\n
    在看完这条消息后，我立马检查了所有代码，防止这款应用在我不知情的情况下，被他人加入恶意代码，但我一无所获。
    \n现就相关事宜申明如下：
    \n一、我开发的所有程序都没有侵犯到用户的隐私。
    \n\n
    在这个应用中，申请的全部权限为：
    \n<uses-permission android:name="android.permission.INTERNET" />
    \n<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    \n<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    \n<uses-permission android:name="android.permission.SET_WALLPAPER" />
    \n<uses-permission android:name="android.permission.READ_PHONE_STATE" />
    \n<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    \n懂点Android技术的都知道，这些权限都是为了让该软件的功能，能够正常工作所必须的权限（连接网络，获取网络状态，下载壁纸时读写SD卡，设置壁纸，读取手机状态）和Admob的广告精准推送所需要的权限（位置信息，读取手机状态）。
    \n至于获取用户浏览历史记录、短信、语音邮件密码的这些明显侵犯用户隐私的行为，完全是子虚乌有。一方面并没要申请相关的权限；另一方面我还真不知道怎样获取这些敏感信息。另外，admob的精准广告服务中可能是会针对用户的地理位置等信息推送更准确的广告服务。
    \n关于这款应用能获取的设备标识号是用来区分设备的唯一性，免去用户注册的麻烦，而能给用户提供收藏图片的功能；而诸如获取手机屏幕大小是为了能够智能适配合适的图片。在这些设备信息中，请问哪一条会侵犯到用户的隐私。
    \n另外说我可以获取浏览历史信息，这简直就是个天大的笑话。如果懂一点程序的就会知道，要获取浏览器信息必须在程序里申请com.android.browser.permission.READ_HISTORY_BOOKMARKS权限。我的程序完全没有获取到权限，怎么能够获取到历史信息，真是笑话！！！
    \n\n
    二、Android手机的权限管理，在任何没有刷过第三方rom的手机上是很严格的。
    \n Android手机的权限管理，在任何没有刷过第三方rom的手机上是很严格的，在没有相关权限的情况下，要获取那些信息，是完全不可能的。就算是被刷过Rom的手机，也只有具有该ROM制作人的加密签名的程序，才能完成一些不安全的操作。
    \n我所需要的权限在用户安装的时候会很明确的告诉用户，下面我就给大家展示一下我应用申请的权限和另外一个著名的壁纸的应用background和一款管理短信的应用申请的权限。
    \n\n
    我的软件需要的权限：
    \n\n
    看看background（另外一款壁纸的应用）申请的权限：
    \n\n
    Handcent SMS申请的权限：
    \n\n\n
    短信有短信的权限，联系人有联系人的权限，我都没要申请，请问我如何获取相关的信息。
    \n\n
    三、应用主要面向外国用户，但绝对没有获取那些高敏感度的隐私信息！
    \n\n
    该应用主要面向外国用户（国内由于网络原因无法正常使用），连接服务器端能够获取到精确适配终端的图片，这是一款非常有用，也深受用户喜爱的应用。它确实拥有数量众多（几百万）的用户，但绝对没有获取那些高敏感度的隐私信息！我每天都收到很多用户的反馈邮件告诉我这个软件多么棒，给他们带来多少乐趣！
    \n\n
    四、我本人始终与业界同仁一道，希望建立诚实守信、和谐共生的Android产业生态系统。
    \n\n
    随着Android开放性操作平台手机的广泛使用，其应用软件开发市场正呈现蓬勃发展景象。对于提醒用户警惕来自手机上的威胁，我本人向来都是强烈支持的！本人一直始终与业界同仁一道，一直为共建诚实守信、和谐共生的Android产业生态系统而努力，将力量专注于用户需求和技术创新，创造更被用户喜欢的软解，并致力于推动手机应用软件产业持续健康发展。
    \n\n
    在此，本人郑重申明，该应用没有获取任何诸如“浏览历史记录，短信，语音邮件密码等”这种高敏感度的信息，并和国外的原作者取得联系，让其修正自己的言论并发布公开道歉，同时对于这种不负责任的言论和评价观点，对我及与我相关的应用进行不负责任的报道造成的影响给予补偿，我将保留追究其法律责任的权利。

    \nupdate：
    \n写完申明后，去看消息出处看到其竟然做了修改，我早料到其会做相关的行为，所有早些时候截了屏幕如下：
    \n\n\n
    而现在的文章被修改为：
    \n\n\n
    看我用鼠标标识的地方，对关键信息进行了修改，感兴趣的人可以去 http://mobile.venturebeat.com/2010/07/28/android-wallpaper-app-that-steals-your-data-was-downloaded-by-millions/ 查看原文，对于这种标题党用子虚乌有的事情炒作，等消息传播后再修改自己的内容算什么行为！而对国内部分媒体在传播时不但不对真实性进行验证，还添油加醋，歪曲意思的报道，我非常无奈（看到有人还说可以获取信用卡信息，还加密传输，我实在无语）。
    \n\n
    按照我个人的感觉，他们应该紧接着要开始拿这个事件来炒作自己的产品了，我个人懒得去关注，如果有人发现有人借此炒作自己的产品，请帮忙分析分析，看看到底是什么人用这样手法。
    \n\n
    再次update！！！
    \n\n
    通过email和mylookout的人取得联系，说明我取得诸如设备号，手机屏幕大小是为了更智能的给设备适配图片，而获取部分的sim卡号是后来用户反馈说自己换了手机还想使用之前的收藏记录才使用的，这些信息只在该应用中使用，并没提供给任何第三方！
    \n\n
    同时让其确认venturebeat上文章中说到的获取浏览器历史，短信息，密码等高敏感性信息是否是他们说的还是写文章的人自己写的（Lots of my users send me the email ask me why I collect their text message and voicemail passward, I just want to make sure whether you and your ceo said that  I collected browsing history,text message ,voicemail passward during the meeting.）。
    \n\n
    其cto给我回复说他们没有说过我的应用获取过诸如text messages or browsing history这些信息（ We never stated that the wallpaper applications gathered users text messages or browsing history.），是媒体在撰写和传播的时候错误报道了（A member of the press misreported our research and he has since corrected it. ）。
    \n\n
    我非常无语～
    \n\n
    2010年8月4日第二次次update！
    \n\n
    多谢这些天很多朋友的关心，我很好，谢谢！这些天和google android组，lookout公司和venturebeat的作者，以及国内外很多媒体，博客们，记者们都有很多的接触。
    \n\n
    1. google就前段时间将应用暂停和我一起分析了这个应用，今天发来调查的结果：
    \n\n
    Our investigation has concluded that there's no obvious malicious code in your apps, though the implementation accesses data that it doesn't need to.  We've restored your apps (and they'll be available on Market again once you publish them), and are looking forward to seeing them updated to use ANDROID_ID.  We are likely to make a statement about this issue this week--I'll let you know.
    \n\n
    我早就说过，我配合调查，我把代码提供给他们，google也做出了公正的评判，另外也给我提了一些建议（ANDROID_ID）。
    \n\n
    2. 当时写这篇报道的venturebeat记者Dean Takahashi发来了mail，为自己犯的错误道歉，并道歉该事带来的恶劣影响，会再写一篇文章澄清这个事情以消除影响。
    \n\n
    3. 那个安全公司lookout的人写邮件来要于我一起“ We wanted to coordinate with you to prevent further misunderstandings. ”。
    \n\n
    4.好几个不认识的国外记者很负责任，发邮件和gt和我交流询问事情的真相，并帮我喊冤，谢谢这些有职业精神的记者们。

    个人认为，如果StDev很大，表示各个包的延时的差别很大，网络不太稳定。不过由于中间点是路由器，一般路由器可能会对icmp包做限制或者优先丢弃，所以中间节点的StDev可以忽略不看。

    nginx的upstream目前支持5种方式的分配
    \n\n
    1、轮询（默认）
    \n每个请求按时间顺序逐一分配到不同的后端服务器，如果后端服务器down掉，能自动剔除。
    \n\n
    2、weight
    \n指定轮询几率，weight和访问比率成正比，用于后端服务器性能不均的情况。
    \n例如：
    \n`upstream bakend {
    \nserver 192.168.0.14 weight=10;
    \nserver 192.168.0.15 weight=10;
    \n}
    \n\n
    3、ip_hash 
    \n每个请求按访问ip的hash结果分配，这样每个访客固定访问一个后端服务器，可以解决session的问题。
    \n例如：
    \nupstream bakend {
    \nip_hash;
    \nserver 192.168.0.14:88;
    \nserver 192.168.0.15:80;
    \n}
    \n\n
    4、fair（第三方）
    \n按后端服务器的响应时间来分配请求，响应时间短的优先分配。
    \n`upstream backend {
    \nserver server1;
    \nserver server2;
    \nfair;
    \n}
    \n\n
    5、url_hash（第三方）
    \n按访问url的hash结果来分配请求，使每个url定向到同一个后端服务器，后端服务器为缓存时比较有效。
    \n例：在upstream中加入hash语句，server语句中不能写入weight等其他的参数，hash_method是使用的hash算法<!--more-->
    \n\n
    `upstream backend {
    \nserver squid1:3128;
    \nserver squid2:3128;
    \nhash $request_uri;
    \nhash_method crc32;
    \n}
    \n\n
    tips:
    \n`upstream bakend{#定义负载均衡设备的Ip及设备状态
    \nip_hash;
    \nserver 127.0.0.1:9090 down;
    \nserver 127.0.0.1:8080 weight=2;
    \nserver 127.0.0.1:6060;
    \nserver 127.0.0.1:7070 backup;
    \n}
    \n在需要使用负载均衡的server中增加
    \nproxy_pass http://bakend/;
    \n\n
    每个设备的状态设置为:
    \n1.down 表示单前的server暂时不参与负载
    \n2.weight 默认为1.weight越大，负载的权重就越大。
    \n3.max_fails ：允许请求失败的次数默认为1.当超过最大次数时，返回proxy_next_upstream 模块定义的错误
    \n4.fail_timeout:max_fails次失败后，暂停的时间。
    \n5.backup： 其它所有的非backup机器down或者忙的时候，请求backup机器。所以这台机器压力会最轻。
    \nnginx支持同时设置多组的负载均衡，用来给不用的server来使用。
    \n\n
    client_body_in_file_only 设置为On 可以讲client post过来的数据记录到文件中用来做debug
    \nclient_body_temp_path 设置记录文件的目录 可以设置最多3层目录
    \nlocation 对URL进行匹配.可以进行重定向或者进行新的代理 负载均衡

    \nsqlInsert = "INSERT logs_downloads.....balalaalala
    \n5. 写到sql文件里
    \nsqlfile.puts( sqlInsert )
    \n6. 调mysql直接导入sql
    \n里面还有一些数据的清洗和排重工作～
    \n每天的日志文件差不多500w行，解析生成sql的过程不理想（其中没用数据库操作）～ 难道是我磁盘性能很糟糕～～
    \n过程看到基本上都没问题，无外乎解析文件，写文件的操作，不应该慢成这样的，最后把目光放在了数据的清洗和排重工作种，这个过程是想在入库的时候就把一些虚假的量排除掉，于是我们自己设计了一个算法来过滤，算法的逻辑很简单，根据一些参赛md5出一个key，然后把这个key丢在Array中，然后用include?来判断这个key是否已经存在，问题就出在这里！
    \n\n
    ruby的Array中的include?是需要很小心的，我之前想当然的认为这个方法应该很快，也没仔细看就用了，结果发现问题就在这个方法上，直接上下源码看看：
    \n
    \n当看到:
    \n`
    \nfor (i=0; i #blalalal
    \n}
    \n
    \n\n
    这个的时候我就明白了，果然，这个方法直接遍历Array，然后你可以想想当我有个500w大小的Array的时候，再用include?是何等的情景啦～
    \n修改方案很容易了，改用hash就好了，不多说～～

    \n1. 需要支持快捷键（最好是手不离开键盘能完成全部操作，或者是纪录，整理list的主要工作）
    \n2. 需要支持子任务（最好是不限制级的，目前能用到3级别）
    \n3. 界面简洁，再简洁
    \n4. 支持多端访问，至少在电脑和手机（android&iphone)可以使用
    \n5. 可以打印或者email给朋友
    \n\n
    最终还是回到了Google Task，经过一段时间的使用，我现在已经非常喜欢Google Task，也给我的效率带来很大帮助，我可以把我的方式分享下。
    \n1. 每天开电脑的第一件事情就是开gmail，处理完邮件开始工作，顺手把gmail里把Google Task打开，并pop up出一个单独的窗口，拖拉到合适的大小；（我工作的时候是两个显示器，就把这个窗口一直放在外接显示器的边上，抬眼可见）
    \n2. 每周一个list，名字是时间范围，比如2012.02.06－2012.02.12；
    \n3. 周一的时候会尽量把本周要做的事情列进去（按照事情的类型或者项目，比如公司事务，eoemarket相关），再把要做的事情一个一个输入进去，Google Task的输入很方便，用好tab键和shift tab键来调整层级；用好Ctrl + Up和Ctrl + Down来调整顺序，用Shift + Enter进入到具体的事情中撰写详细，写完再Shift + Enter回到列表；
    \n4. 每次做事情的时候，可以用Tab再细分，一个一个执行掉；完成后回到Google Task，用Option + Enter 标识这个完成（Option + Enter这个快捷键在官方帮助文档和tips里都没，我自己找出来的，mac电脑）；另外勾选上级条目可以把下级条目都标记完成～
    \n5. 每次遇到新的事情直接添加进去，经常review，如此反复就好了～
    \n6. 有的时候还通过打印和发送邮件通知其他人我都做了什么；
    \n\n
    此外，Google Task提供如下方式的使用，我个人觉得足够了
    \n1. gmail中集成/igoogle集成
    \n2. iphone客户端，android客户端（第三方开发的）
    \n3. chrome插件
    \n4. 桌面客户端（没找到，也不怎么用）
    \n5. api接口（或者自己写）
    \n\n
    如果硬说还可以有些期待的话，我的是这样的：
    \n1. 谁写个更好用的iphone客户端（现在app store上的质量一般，而且收费，哪天我心血来潮我来写一个去～）
    \n2. 可以把一个list里没完成的复制到另外一个list中
    \n3. 真木了
    \n\n
    我的个人建议是：必须用好快捷键！
    \n\n
    希望我的这篇介绍能让你喜欢Google Task，并对自己有所帮助
    \n如果你有兴趣，可以看看它的官方帮助页面

    \n\n
    第一阶段：这是个大家庭（2009年）
    \n社区创建之初，android在国内还很不活跃，社区人数不多，仅有几个好朋友开始活跃，开始摸索android是个什么，可以做什么，社区人不多，但是大家都蛮熟悉，社区象一个大家庭，大家经常熬夜研究文档，代码，试验。

    第二阶段：曲折的发展之路（2010年）
    \n到了2010年前后，有了第二批做android的人，社区得到大家的认可和口碑相传，很快服务器就开始吃紧，开始不稳定，那会服务器还托管在上海一个机房，而后就遭受其他网站的牵连，机房被封，服务器被拔线，几经折腾，后来索性搬迁到国外，虽然一些地方速度慢一些，但是终于稳定了；这段时间很曲折，在国内换从上海换到成都，又换到北京，险些万劫不复，幸好那会备份转移做的比较勤，只丢了一点点数据，万幸！
    \n\n
    第三阶段：蓬勃发展，开拓思路（2011年）
    \n迁往国外后的一段日子，android终于爆发了，开发者数量也开始爆发了，越来越多的人加入android技术阵营，社区一次一次的加带宽，加内存，加磁盘，一次一次的升级，优化，最后我们再次迁回国内，有了自己的机房和专属服务器；社区也做过一次大的升级成开发者门户，想给大家提供更多的内容。
    \n\n
    第四阶段：新起点，新目标
    \n2011底，我们酝酿新的改版，我们一直在思考如何把eoeAndroid社区做好，让更多的人得到帮助，让更多的人踏入android行业的大门；我们设计和讨论过n多方案，最终我们选择的方向是“[color=Red]源于内心，回归更纯粹的技术[/color]”，或许是因为技术出身，对技术有着特殊的感情，我们觉得eoeAndroid一直都有这么一些精神：专业 专注 自由 开放 分享 。我们大家都专注android技术领域，都是专业的人才，我们会积累沉淀好的资源和文章，用心运营；我们也崇尚自由的氛围，开放的态度，乐于分享我们的经验和知识。

    \nreal    0m0.974s
    \nuser    0m0.813s
    \nsys 0m0.063s

    有些人可能对我多少有些了解，应该算国内第一批开始搞android相关的人，09年创办的android开发社区（eoeandroid.com）现在也是国内android开发人员最活跃的社区，我写过一些代码，也写过一些技术的文章，也做过android应用，也见过很多android的技术，也给公司（eoe）招了不少android技术人员，也给不少朋友奇特推荐过android技术的人，我下面会分享我对android技术人员招聘的一些看法。
    \n\n
    1. 首先看为人：品性很重要
    \n\n
    或许是因为我们是创业公司，会严格选择每一个进来的人，特别是技术的人。技术很重要，但是在我这边不是第一位的，人品和性格是第一的，创业公司唯一不变的就是变化，如果人品不过关的人肯定待不住，如果性格合不来的人肯定待不久。有人说这个很虚，见一面怎么可能看出品性，其实不难，一举一动，言语措辞都很简单就可以看出一个人的内在（因为技术的人为人真的很简单），所以，如果你去面熟，表现真实的自己，对公司，对个人都是有好处的，合得来就是合得来，合不来强求也没用，这本是个双向选择的事情，不存在谁强势谁弱势。积极，主动，自信，阳光是比较好的品格～
    \n\n
    2. 接着看技术：基本功需要有体系，够扎实，思维要跳跃
    \n\n
    如果来eoe面试过的人应该知道，我们面android有一套笔试题，但是java的，很多人不理解可能会问我来面android的为啥让我做java的题？其实很简单，java是基础，我们的笔试题会涉及到基础的，算法的，开放性的试题，我们需要全面的了解一个人。每个题目都很重要，所以，如果去面试，如果对方是精心设计的题，请认真一点回答，记住认真不是死板，答题看的是基础和思维，细节无所谓，因为有真正干活的时候有google，有api～
    \n\n
    3. 然后看经验：经验很重要，你必须对你做过的项目了如指掌
    \n\n
    做完题目，我们一般就正式面试了，会问问笔试题目上你的感觉和具体一个问题的思路，然后才开始问之前的经验，我们的要求是必须真正做过项目，如果没项目，应用也行，其实需要的就是一个关键点：你真正操作过一个应用，对你做过的模块必须了如指掌，我们不会问太多项目，让你一个最熟悉的或者最喜欢的项目，问的很细节，细节到你证明这个项目自己之前是用心做的，或者证明你在这个项目就是个打酱油的。
    \n\n
    然后会问点和android相关的东西，一般容易的，中等的和比较刁钻的问题都会问一些，刁钻的比如会问你现场保护的机制，方式，为什么要现场保护等等问题，如果你是个做技术爱思考的人，这些问题应该不难，如果你虽然做过1－2年android，但是每个方面都很泛泛，那你肯定会被问的傻傻的。
    \n\n
    最后会问一些开放性的问题，都是很随机的题目，比如桌子上的一个杯子等等都可能会被问～～这个地方主要看整体的思维和分析问题的能力。
    \n\n
    4. 做决定：合适还是不合适，或者留题目，做个小测试
    \n\n
    如此过程，我们基本上就能判断一个人是否符合我们要求，如果不满足，我们基本会很直接告诉原因是什么，哪个地方我们觉得不合适，你以后应该注意什么？如果我们觉得满足预期，可能就收了；如果我们拿不准，但是觉得你潜力很好，可能会留个题目，做个小东西，不会很难，做的时候请注意自己的编码风格，整体项目结构等等，这些是关键因素～
    \n\n
    如上过程，就是我在招android技术人员的一些思路和过程，我们是创业公司，相对看的更全面的能力，但是我个人觉得企业的思维或许都差不多，如果你要找android相关的工作，请参考～
    \n\n
    另外，android开发社区 里有很多企业招聘android技术人员，大家可以多关注，希望大家能找到自己满意android工作～记得经常来android开发社区活动～
    \n\n
    再顺便提一下，我们（eoe）长期招合适的android技术，如果你有兴趣，可以联系我～

    这本书是国内第一本android的技术的书，当时的android sdk还是1.5版，上市快3年了，内容相对偏老的，出版社一再催我能更新到最新的sdk版本，再把之前用户反馈比较多的问题完善下～是不是真的需要抽点时间来出第二版了呢？

I'm not an expert here, but I've put together some notes on how to start working on a Rails application whilst being test-driven all the time.As an example I will use a word-learning web application. The simplest use case is to display a random word object (with its polish translation) from the database.Every time we refresh we want to see a different word.1. Create a new Rails applicationsrails my_appcd my_appRun tests with 'rake test'. It fails due to missing database configuration.2. Set up the databases - config/database.ymlThe code below assumes sqlite3 databases. development:   adapter: sqlite3   database: db/my_app_development.sqlite test:   adapter: sqlite3   database: db/my_app_test.sqlite'rake test' now runs fine.3. Create a Word class with a corresponding unit testscript/generate model Word4. Write a unit test for the Word class. Edit the test/unit/word_test.rb. def test_word_is_english_and_polish   word = Word.new :eng=>'never', :pl=>'nigdy'   assert_equal 'never', word.eng   assert_equal 'nigdy', word.pl end'rake test' now fails due to missing words table.5. Edit db/migrate/001_create_words.rbWe are using a migration here in order to create a table. It's a recommended way of dealing with database changes.  def self.up    create_table :words do |t|      t.column :eng, :string      t.column :pl, :string    end        Word.new(:eng=>'yes', :pl=>'tak').save    Word.new(:eng=>'no', :pl=>'nie').save    Word.new(:eng=>'everything', :pl=>'wszystko').save  end  def self.down    drop_table :words  endThe sample words that we are adding use Word.new .. lines, will be added to the development database. It's important to distinguish the 'test' and 'development' database. The first one is only used during tests. The latter is used by default when you start the application.Apply the migration with 'rake db:migrate'.'rake test' now succeeds with the following:'1 tests, 2 assertions, 0 failures, 0 errors'6. Fixtures and test for word.random. Edit word_test again.It's not easy to test a method which behaves randomly. Let's assume that it's enough to test that if we have only two words in our database then one of them should be called at least once per 10 calls.fixtures :wordsdef test_random results = [] 10.times {results << Word.random.eng} assert results.include?("yes")endNote the 'fixtures :words' line. Edit the 'words.yml' file.yes: id: 1 pl: 'tak' eng: 'yes'no: id: 2 pl: 'nie' eng: 'no'This will be loaded to the test database before every run of tests.7. Implement the Word.random method  def self.random    all = Word.find :all    all[rand(all.size)]  endWarning: The code above could be slow for many words in a database (we retrieve all words only for selecting a random element). It's good enough for our needs.8. Generate the Words controller with a 'learn' actionscript/generate controller Words learn9. Write a test for the learn methodJust as there is a one-to-one ratio between unit tests and models, so there is between functional tests and controllers. The Controller's responsibility is to retrieve objects from the Model layer and pass them to the View. Let's test the View part first. We use the 'assigns' collection which contains all the objects passed to the View.def test_learn_passes_a_random_word  get 'learn'  assert_kind_of Word, assigns('word')end10. Make the Test Passdef learn  @word = Word.newend11. Write more tests in the words_controller_testHow can we test that controller uses the Word.random method? We don't want to duplicate the tests for the Word.random method.Mocks to the rescue! We will only test that the controller calls the Word.random method. The returned value will be faked with a prepared word.Let's install the mocha framework:gem install mochaNow we can use 'expects' and 'returns' methods.'expects' is used for setting an expectation on an object or a class. In this case we expect that the 'random' method will be called. We also set a return value by using 'returns' method. Setting a return value means faking (stubbing) the real method. The real Word.random won't be called. If an expectation isn't met the test fails.require 'mocha'def test_learn_passes_a_random_word  random_word = Word.new  Word.expects(:random).returns(random_word)  get 'learn'  assert_equal random_word, assigns('word')end'rake test' now fails. The Word.method wasn't called.12. Rewrite the implementationdef learn  @word = Word.randomend'rake test' now passes.13. Test that a word is displayed:Extend the existing test with assert_tag calls.def test_learn_passes_a_random_word  random_word = Word.new(:pl=>'czesc', :eng=>'hello')  Word.expects(:random).returns(random_word)  get 'learn'  assert_equal random_word, assigns('word')  assert_tag :tag=>'div', :child => /czesc/  assert_tag :tag=>'div', :child => /hello/end14.

    \n\n

    \n\n
    things = Thing.find(:all)
    \nrandom_things = []
    \n3.times do
    \nrandom_things << things[rand(things.size)]

    \nrandom_things = []
    \nwhile random_things.size < 3

    这个方法只是先随机取出ids较，然后再取ids对应的记录，比前面说的那个有个好处就是不会消耗太多的系统资源，比起第一种方法会快很多。
    \n\n
    3.在数据库层面上做
    \n\n
    <code>random_things = Thing.find(:all, :limit => 3, :order => 'random()')</code>
    \n\n
    是不是神奇呢，我们直接把:random(如果是MySQL则需要使用 rand()) 传给Find方法就可以了，这个方法看似比较好，其实不然，其构造出来的SQL比较变形，且对于不同的数据库不能通用。且类似与order by rand() limit 1这样的语句是很畸形的。并且这个sql效率奇低！！

    4.使用offset进一步改进

    \n看看Jsonifier的自我介绍：
    \nJsonifier is a Rails plugin that adds options to the ActiveRecord#to_json method similar to ActiveRecord#to_xml. It's time to treat the JSON encoding of AR objects with more respect ;)The :only, :except, :methods, and :include options are supported. Check out the examples below.

    由于一个系统需要对外提供数据，自然使用widget来实现，JS中自然是对json支持最好，也是就可以吧数据组装成json格式的，再用JS解析显示，于是就有了这个需求：在rails中生成JSON，尽管rails1.1版本就增加了对json的支持，但要想更加灵活，自然使用插件来实现了，而Jsonifier 正是我们需要的。
    \n看看Jsonifier的自我介绍：
    \nJsonifier is a Rails plugin that adds options to the ActiveRecord#to_json method similar to ActiveRecord#to_xml. It's time to treat the JSON encoding of AR objects with more respect ;)The :only, :except, :methods, and :include options are supported. Check out the examples below. 
    \n
    \n安装：
    \n很简单，script/plugin install svn://svn.codefront.net/jsonifier/trunk
    \n
    \n使用：
    \n
    \nRuby代码
    \n
    \n    david = User.find(1)  
    \n    david.to_json # {id: 1, name: "David", awesome: true, created_at: "07/01/2007"}

/>和我一样许多习惯了java的程序员在刚刚开始接触ruby的时候对ruby当中的方法声名以及调用的方式会感到非常的奇怪和别扭。比如我们在ruby当中经常可以看到类似的方法声名 method(arg1, *args), 又如这样的方法 method2(arg2, &block), 等等。相比于java那明确简单的方法声名方式，ruby中的方法声名要灵活许多，下面就ruby当中常见的几种方法声名的形式，以及方法调用的方式做一个简要的总结：1. 首先，不同于java的方法声名，ruby中的方法可以接收的参数是可变的，而不是像java那样必须和方法声名中的参数类型相等，个数相等。当你希望ruby方法接收一个或者多个参数的时候，可在普通的参数名前放置一个星号(*),比如：<div class="typocode"><pre><code class="typocode_ruby "><notextile><span class="keyword">def </span><span class="method">varargs</span><span class="punct">(</span><span class="ident">arg1</span><span class="punct">,</span> <span class="punct">*</span><span class="ident">rest</span><span class="punct">)</span>  “<span class="constant">Received</span> <span class="comment">\#{arg1} and \#{rest.join(', ')}”</span><span class="keyword">end</span><span class="ident">varargs</span><span class="punct">(&quot;</span><span class="string">one</span><span class="punct">&quot;)</span> <span class="comment">#=&gt;&quot;Received one and &quot;</span><span class="ident">varargs</span><span class="punct">(&quot;</span><span class="string">one</span><span class="punct">&quot;,&quot;</span><span class="string">two</span><span class="punct">&quot;)</span> <span class="comment">#=&gt;&quot;Received one and two&quot;</span><span class="ident">varargs</span><span class="punct">(&quot;</span><span class="string">one</span><span class="punct">&quot;,&quot;</span><span class="string">two</span><span class="punct">&quot;,&quot;</span><span class="string">three</span><span class="punct">&quot;)</span> <span class="comment">#=&gt;&quot;Received one and two, three&quot;</span>以上代码出自《<span class="ident">programming</span> <span class="ident">ruby</span> 中文版》<span class="ident">p80</span></notextile></code></pre></div>在这里，varargs方法的第二个形参前有一个星号，表示将方法中第二个以后的所有参数都装到一个数组当中，然后赋值给rest. 所以当方法声名的参数前边又一个*的时候，代表：将方法调用时传入的所有<b>除之前已匹配完毕的参数外的剩余参数</b>放入一个Array并将其赋值给*后边的形参。2. 我们也经常会见到在方法声名的参数当中有“&args”的形式，比如<div class="typocode"><pre><code class="typocode_ruby "><notextile><span class="keyword">class </span><span class="class">TaxCalculator</span>  <span class="keyword">def </span><span class="method">initialize</span><span class="punct">(</span><span class="ident">name</span><span class="punct">,&amp;</span><span class="ident">block</span><span class="punct">)</span>    <span class="attribute">@name</span><span class="punct">,</span><span class="attribute">@block</span> <span class="punct">=</span> <span class="ident">name</span><span class="punct">,</span> <span class="ident">block</span>  <span class="keyword">end</span>  <span class="keyword">def </span><span class="method">get_tax</span><span class="punct">(</span><span class="ident">amount</span><span class="punct">)</span>    <span class="punct">&quot;</span><span class="string"><span class="expr">\#{@name}</span> on <span class="expr">\#{amount}</span> = <span class="expr">\#{@block.call(amount)}</span></span><span class="punct">&quot;</span>  <span class="keyword">end</span><span class="keyword">end</span><span class="ident">tc</span> <span class="punct">=</span> <span class="constant">TaxCalculator</span><span class="punct">.</span><span class="ident">new</span><span class="punct">(&quot;</span><span class="string">Sales tax</span><span class="punct">&quot;){|</span><span class="ident">amt</span><span class="punct">|</span> <span class="ident">amt</span> <span class="punct">*</span> <span class="number">0.075</span><span class="punct">}</span><span class="ident">tc</span><span class="punct">.</span><span class="ident">get_tax</span><span class="punct">(</span><span class="number">100</span><span class="punct">)</span> <span class="comment">#=&gt;&quot;Sales tax on 100 = 7.5&quot;</span><span class="ident">tc</span><span class="punct">.</span><span class="ident">get_tax</span><span class="punct">(</span><span class="number">200</span><span class="punct">)</span> <span class="comment">#=&gt;&quot;Sales tax on 250 = 18.75&quot;</span>以上代码出自《<span class="ident">programming</span> <span class="ident">ruby</span> 中文版》<span class="ident">p81</span></notextile></code></pre></div>当方法的<b>最后一个参数</b>前缀为&,那么改方法调用的后边可以跟一个block，同时方法会将block转换为一个Proc对象，然后赋值给该参数。3. 我们经常可以在rails的文档中看到这种方法声名：<div class="typocode"><pre><code class="typocode_ruby "><\nno\ntextile><span class="keyword">def </span><span class="method">method</span><span class="punct">(</span><span class="ident">id</span><span class="punct">,</span><span class="ident">option</span><span class="punct">={})</span>  <span class="punct">...</span><span class="keyword">end</span></notextile></code></pre></div>然后我们调用的时候可以以任意的顺序传入key=>value hash pair 如：<div class="typocode"><pre><code class="typocode_ruby "><notextile><span class="ident">method</span><span class="punct">(</span><span class="number">5</span><span class="punct">,</span><span

    引言:张雪同学blog上的这个文章很是不错，从一个侧面展示了Ruby的一些和别的不一样的特性，显出了其灵活和强大，很值得仔细看看～会使得你对ruby中的方法调用更加理解～<br/><br />来源:*for each_day in life: ruby中的方法调用<br />*地址:*http://blog.snowonrails.com/articles/2007/05/15/ruby%E4%B8%AD%E7%9A%84%E6%96%B9%E6%B3%95%E8%B0%83%E7%94%A8<br; />*标题:*ruby中的方法调用<br />*内容摘要:<br />和我一样许多习惯了java的程序员在刚刚开始接触ruby的时候对ruby当中的方法声名以及调用的方式会感到非常的奇怪和别扭。比如我们在ruby当中经常可以看到类似的方法声名 method(arg1, args), 又如这样的方法 method2(arg2, &block), 等等。相比于java那明确简单的方法声名方式，ruby中的方法声名要灵活许多，下面就ruby当中常见的几种方法声名的形式，以及方法调用的方式做一个简要的总结：1. 首先，不同于java的方法声名，ruby中的方法可以接收的参数是可变的，而不是像java那样必须和方法声名中的参数类型相等，个数相等。当你希望ruby方法接收一个或者多个参数的时候，可在普通的参数名前放置一个星号(),比如：<div class="typocode"><pre><code class="typocode_ruby "><notextile><span class="keyword">def </span><span class="method">varargs</span><span class="punct">(</span><span class="ident">arg1</span><span class="punct">,</span> <span class="punct"></span><span class="ident">rest</span><span class="punct">)</span>  “<span class="constant">Received</span> <span class="comment">\#{arg1} and \#{rest.join(', ')}”</span><span class="keyword">end</span><span class="ident">varargs</span><span class="punct">(&quot;</span><span class="string">one</span><span class="punct">&quot;)</span> <span class="comment">#=&gt;&quot;Received one and &quot;</span><span class="ident">varargs</span><span class="punct">(&quot;</span><span class="string">one</span><span class="punct">&quot;,&quot;</span><span class="string">two</span><span class="punct">&quot;)</span> <span class="comment">#=&gt;&quot;Received one and two&quot;</span><span class="ident">varargs</span><span class="punct">(&quot;</span><span class="string">one</span><span class="punct">&quot;,&quot;</span><span class="string">two</span><span class="punct">&quot;,&quot;</span><span class="string">three</span><span class="punct">&quot;)</span> <span class="comment">#=&gt;&quot;Received one and two, three&quot;</span>以上代码出自《<span class="ident">programming</span> <span class="ident">ruby</span> 中文版》<span class="ident">p80</span></notextile></code></pre></div>在这里，varargs方法的第二个形参前有一个星号，表示将方法中第二个以后的所有参数都装到一个数组当中，然后赋值给rest. 所以当方法声名的参数前边又一个*的时候，代表：将方法调用时传入的所有<b>除之前已匹配完毕的参数外的剩余参数</b>放入一个Array并将其赋值给*后边的形参。2. 我们也经常会见到在方法声名的参数当中有“&args”的形式，比如<div class="typocode"><pre><code class="typocode_ruby "><notextile><span class="keyword">class </span><span class="class">TaxCalculator</span>  <span class="keyword">def </span><span class="method">initialize</span><span class="punct">(</span><span class="ident">name</span><span class="punct">,&amp;</span><span class="ident">block</span><span class="punct">)</span>    <span class="attribute">@name</span><span class="punct">,</span><span class="attribute">@block</span> <span class="punct">=</span> <span class="ident">name</span><span class="punct">,</span> <span class="ident">block</span>  <span class="keyword">end</span>  <span class="keyword">def </span><span class="method">get_tax</span><span class="punct">(</span><span class="ident">amount</span><span class="punct">)</span>    <span class="punct">&quot;</span><span class="string"><span class="expr">\#{@name}</span> on <span class="expr">\#{amount}</span> = <span class="expr">\#{@block.call(amount)}</span></span><span class="punct">&quot;</span>  <span class="keyword">end</span><span class="keyword">end</span><span class="ident">tc</span> <span class="punct">=</span> <span class="constant">TaxCalculator</span><span class="punct">.</span><span class="ident">new</span><span class="punct">(&quot;</span><span class="string">Sales tax</span><span class="punct">&quot;){|</span><span class="ident">amt</span><span class="punct">|</span> <span class="ident">amt</span> <span class="punct"></span> <span class="number">0.075</span><span class="punct">}</span><span class="ident">tc</span><span class="punct">.</span><span class="ident">get_tax</span><span class="punct">(</span><span class="number">100</span><span class="punct">)</span> <span class="comment">#=&gt;&quot;Sales tax on 100 = 7.5&quot;</span><span class="ident">tc</span><span class="punct">.</span><span class="ident">get_tax</span><span class="punct">(</span><span class="number">200</span><span class="punct">)</span> <span class="comment">#=&gt;&quot;Sales tax on 250 = 18.75&quot;</span>以上代码出自《<span class="ident">programming</span> <span class="ident">ruby</span> 中文版》<span class="ident">p81</span></notextile></code></pre></div>当方法的<b>最后一个参数</b>前缀为&,那么改方法调用的后边可以跟一个block，同时方法会将block转换为一个Proc对象，然后赋值给该参数。3. 我们经常可以在rails的文档中看到这种方法声名：<div class="typocode"><pre><code class="typocode_ruby "><
    \nno
    \ntextile><span class="keyword">def </span><span class="method">method</span><span class="punct">(</span><span class="ident">id</span><span class="punct">,</span><span class="ident">option</span><span class="punct">={})</span>  <span class="punct">...</span><span class="keyword">end</span></notextile></code></pre></div>然后我们调用的时候可以以任意的顺序传入key=>value hash pair 如：<div class="typocode"><pre><code class="typocode_ruby "><notextile><span class="ident">method</span><span class="punct">(</span><span class="number">5</span><span class="punct">,</span><span class="ident">key1</span><span class="punct">=&gt;</span><span class="ident">value1</span><span class="punct">,</span><span class="ident">key2</span><span class="punct">=&gt;</span><span class="ident">value2</span><span class="punct">,...)</span></notextile></code></pre></div>在参数列表中，<b>当hash参数在正常参数之后,并且位于任何数组或block参数之前</b>，我们就可以直接用key=>value对，而不用加{}。所有的这些key=>value对会被集合到一个hash，然后赋值给形参，传入方法。

    \n按照和透明同学讨论的结果，生成简历属于紧急需求，于是经过简单的规划设计就开始了，在技能云的简历是按照技能云记载的你参与的项目自动生成的，辅助其他一些信息，比如你掌握的技能和扮演过的角色，生成一份能真实的展现自我实力的简历。
    \n目前还不允许个人编辑自己的简历，这个后期看情况可能会加入（还要看情况），目前看不到这个需求。针对这个功能，还请各位提提意见和建议，以更加符合大家的口味，谢谢。
    \n如想看看效果，可以看这里是我的简历，其他人的简历，你可以在他们的介绍页面看到，登录后在最上方可以看到自己简历的链接，希望大家喜欢这个功能。

    以前在JavaEye的一个讨论里，有位同志说“简历嘛，大家都知道，肯定是有水分的”。于是我在另一个blog里说到，简历里唯一有意义的，就是工作经历。认真回想一下，我在看应聘者的简历时，也基本上不看基本信息、自我评价之类的，只看工作经历：做过什么项目，用过什么技术，比说什么“熟练”、“精通”要有意义得多。我的期望、我的评估、整个后续的面试过程都是围绕着工作经历来展开的。
    \n
    求职者的工作经历，这份信息对于潜在雇主有价值。但这份价值在求职者自己身上实现了多少？作为软件开发者，不妨问问自己：还有谁记得你几年前完成的那些“不可能的任务”？还有谁记得你通宵加班为项目做出的贡献？还有谁记得客户和领导曾给你的赞扬？有多少求贤若渴的潜在雇主想要知道你曾经那些了不起的成就，却无从获取这些信息？那么这份信息的价值去了哪里？我们把工作经历告诉了谁？是的，我们把工作经历写在简历里，把简历放在了招聘网站；而招聘网站把我们的简历锁起来，把我们的工作经历信息卖给潜在雇主。我们的工作经历，去给招聘网站创造价值了。
    \n

    本文是透明同学为“技能云”写的介绍，看完热血沸腾，转过来激励不断的完善技能云。
    \n以前在JavaEye的一个讨论里，有位同志说“简历嘛，大家都知道，肯定是有水分的”。于是我在另一个blog里说到，简历里唯一有意义的，就是工作经历。认真回想一下，我在看应聘者的简历时，也基本上不看基本信息、自我评价之类的，只看工作经历：做过什么项目，用过什么技术，比说什么“熟练”、“精通”要有意义得多。我的期望、我的评估、整个后续的面试过程都是围绕着工作经历来展开的。
    \n求职者的工作经历，这份信息对于潜在雇主有价值。但这份价值在求职者自己身上实现了多少？作为软件开发者，不妨问问自己：还有谁记得你几年前完成的那些“不可能的任务”？还有谁记得你通宵加班为项目做出的贡献？还有谁记得客户和领导曾给你的赞扬？有多少求贤若渴的潜在雇主想要知道你曾经那些了不起的成就，却无从获取这些信息？那么这份信息的价值去了哪里？我们把工作经历告诉了谁？是的，我们把工作经历写在简历里，把简历放在了招聘网站；而招聘网站把我们的简历锁起来，把我们的工作经历信息卖给潜在雇主。我们的工作经历，去给招聘网站创造价值了。

    \n
    The easiest and fastest way to install Ruby gems is to install them in your local directory, you will need shell access. To install your own gems use the following steps:
    \n
    \n1) Using File Manager in your cPanel make a copy of the .bashrc file in your root directory, name it .bashrc.bak.
    \n2) Now edit the .bashrc file and add the following to the end of the file:
    \n
    \n
    lunix代码
    \n
      \n    
    1. export PATH="$PATH:$HOME/packages/bin:$HOME/.gems/bin"  
      2. \n    
    2. export GEM_HOME="$HOME/.gems"  
      3. \n    
    3. export GEM_PATH="$GEM_HOME:/usr/lib/ruby/gems/1.8"

    5. export GEM_CACHE=”$GEM_HOME/cache”  
      \n    
      6. \n
    \n
    \n
    3) Using your favorite SSH client connect to your site.
    \n
    \n4) at the prompt type:
    \n
    \ncp /usr/lib/ruby/gems/1.8/cache/sources-0.0.1.gem ./
    \ngem install sources-0.0.1.gem
    \ngem update -y
    \n
    \nThis will update rails to the latest version and install it to your local gem directory.
    \n
    \n5) When using a rails application, make sure you add the following to your ./config/environment.rb:
    \n
    \nENV['GEM_PATH'] = '/path/to/your/home/.gems:/usr/lib/ruby/gems/1.8'

    注：在下面做的介绍都是以Weblogic8.1为例的，其它版本的Weblogic可能会有些许不同。
    \n
    \n1) 设置JAVA参数；
    \na) 编辑Weblogic Server启动脚本文件；
    \nBEA_HOME\\user_projects\\domains\\domain-name\\startWebLogic.cmd(startWebLogic.sh on Unix)  
    \nBEA_HOME\\user_projects\\domains\\domain-name\\startManagedWebLogic.cmd(startManagedWebLogic.sh on Unix) --这个是做集群的时候用的
    \nb) 编辑set JAVA_OPTIONS命令，如：set JAVA_OPTIONS=-Xms256m –Xmx256m；
    \n（在UNIX下把MEM_ARGS="-Xms1024m -Xmx1024m -Xmn128m"加到上述两个.sh文件中即可）
    \nc) 保存，重启即可。
    \n注：在WebLogic中，为了获得更好的性能，BEA公司推荐最小Java堆等于最大Java堆。
    \n（这个偶们的设置都是1024M的，反正偶们内存大大的4G呢）
    \n
    \n2) 开发模式 vs. 产品模式；
    \n开发模式和产品模式的一些参数的默认值不同，可能会对性能造成影响，下面是对性能有影响的参数列表：
    \n
    \n\n    \n        \n            \n            \n            \n        \n        \n            \n            \n            \n        \n        \n            \n            \n            \n        \n    \n
    参数开发模式默认值产品模式默认值
    Execute Queue: Thread Count15 threads25 threads
    JDBC Connection Pool: MaxCapacity15 connnections25 connections
    \n
    \n通过启动管理控制台，在域（如：mydomain）> 配置 > 常规选择产品模式。
    \n（这个在创建weblogic的domain的时候是有选择的，选择“产品”模式就可以了，如果后期需要修改，可以按照上面的方法修改）
    \n
    \n3) 尽量开启本地I/O；
    \n通过启动管理控制台，在域（如：mydomain）> 服务器 > server实例（如：myserver）> 配置 > 调整选择启用本地I/O。
    \n注：此值也可通过手动的修改config.xml配置文件。
    \n（这个没有试验过，不晓得有什么效果和好处，知道的告诉偶下下。）
    \n
    \n4) 调优执行队列线程；
    \na) 修改默认执行线程数
    \n在这里，执行队列的线程数表示执行队列能够同时执行的操作的数量。但此值不是设的越大越好，应该恰到好处的去设置它，太小了，执行队列中将会积累很多待处理的任务，太大了，则会消耗大量的系统资源从而影响整体的性能。在产品模式下默认为25个执行线程。
    \n（点：一般来说，其上限是每个CPU对应50个线程，其按照CPU个数线性增长.）
    \n
    \n为了设置理想的执行队列的线程数，我们可以启动管理控制台，在域（如：mydomain）> 服务器 > server实例（如：myserver）> 监视 > 性能中监控最大负载时执行队列的吞吐量和队列中的等待请求数，据此确定理想的数值。
    \n理想的默认执行线程数是由多方面的因素决定的，比如机器CPU性能、总体体系架构、I/O、操作系统的进程调度机制、JVM的线程调度机制。随着CPU个数的增加，WebLogic可以近乎线性地提高线程数。线程数越多，花费在线程切换的时间也就越多；线程数越小，CPU可能无法得到充分的利用。为获取一个理想的线程数，需要经过反复的测试。在测试中，可以以25*CPU个数为基准进行调整。当空闲线程较少，CPU利用率较低时，可以适当增加线程数的大小（每五个递增）。对于PC Server和Windows 2000，则最好每个CPU小于50个线程，以CPU利用率为90%左右为最佳。
    \n通过启动管理控制台，在域（如：mydomain）> 服务器 > server实例（如：myserver）> Execute Queue > weblogic.kernel.Defalt > 配置中修改线程计数。
    \n
    \nb) 设定执行队列的溢出条件；
    \n    Weblogic Server提供给默认的执行队列或用户自定义的执行队列自定义溢出条件的功能，当满足此溢出条件时，服务器改变其状态为“警告”状态，并且额外的再分配一些线程去处理在队列中的请求，而达到降低队列长度的目的。
    \n    通过启动管理控制台，在域（如：mydomain）> 服务器 > server实例（如：myserver）> Execute Queue > weblogic.kernel.Defalt > 配置下面几项：
    \n●队列长度：此值表示执行队列中可容纳的最大请求数，默认值是65536，最后不要手动改变此值。
    \n●队列长度阈值百分比：此值表示溢出条件，在此服务器指出队列溢出之前可以达到的队列长度大小的百分比。
    \n●线程数增加：当检测到溢出条件时，将增加到执行队列中的线程数量。如果CPU和内存不是足够的高，尽量不要改变默认值“0”。因为Weblogic一旦增加后不会自动缩减，虽然最终可能确实起到了降低请求的作用，但在将来的运行中将影响程序的性能。
    \n●最大线程数：为了防止创建过多的线程数量，可以通过设定最大的线程数进行控制。
    \n在实际的应用场景中，应根据具体情况适当的调整以上参数。
    \n
    \nc) 设定执行队列监测行为
    \nWeblogic Server能够自动监测到当一个执行线程变为“阻塞”。变为“阻塞”状态的执行线程将无法完成当前的工作，也无法再执行新请求。如果执行队列中的所有执行线程都变为“阻塞”状态，Weblogic server可能改变状态为“警告”或“严重”状态。如果Weblogic server变为“严重”状态，可以通过Node Manager来自动关闭此服务器并重新启动它。具体请参考：Node Manager Capabilities文档。
    \n通过启动管理控制台，在域（如：mydomain）> 服务器 > server实例（如：myserver）>配置 > 调整下可配置下面几项：
    \n●阻塞线程最长时间：在此服务器将线程诊断为阻塞线程之前，线程必须连续工作的时间长度(秒)。默认情况下，WebLogic Server 认为线程在连续工作 600 秒后成为阻塞线程。
    \n●阻塞线程计时器间隔：WebLogic Server 定期扫描线程以查看它们是否已经连续工作了 "阻塞线程最长时间" 字段中指定的时间长度的间隔时间(秒)。默认情况下，WebLogic Server 将此时间间隔设置为 600 秒。
    \n
    \n5) 调优TCP连接缓存数；
    \nWebLogic Server用Accept Backlog参数规定服务器向操作系统请求的队列大小，默认值为50。当系统重载负荷时,这个值可能过小,日志中报Connection Refused,导致有效连接请求遭到拒绝,此时可以提高Accept Backlog 25%直到连接拒绝错误消失。对于Portal类型的应用,默认值往往是不够的。
    \nLogin Timeout和SSL Login Timeout参数表示普通连接和SSL连接的超时时间,如果客户连接被服务器中断或者SSL容量大,可以尝试增加该值。
    \n通过启动管理控制台，在域（如：mydomain）> 服务器 > server实例（如：myserver）>配置 > 调整下可配置“接受预备连接”。
    \n
    \n6) 改变Java编译器；
    \n标准的Java编译器是javac，但编译JSP servlets速度太慢，为了提高编译速度，可以使用sj或jikes编译器取代javac编译器。下面说说更改Java编译器：
    \n通过启动管理控制台，在域（如：mydomain）> 服务器 > server实例（如：myserver）>配置 > 常规下改变Java 编译器，默认为javac。输入完整路径，如：c:\\visualcafe31\\bin\\sj.exe。然后打开高级选项，在预规划到类路径填写编译 Java 代码时为 Java 编译器类路径预规划的选项，如：BEA_HOME\\jdk141_02\\jre\\lib\\rt.jar。
    \n
    \n7) 使用Webogic Server集群提高性能；
    \n具体关于如何配置Weblogic集群，我就不细说了。详情可参考：Introduction to WebLogic Server Clustering。
    \n
    \n8) Weblogic EJB调优
    \n由于EJB2.0已经很少项目在用了，EJB3.0再成熟一点，我再补充这一部分吧！
    \n
    \n9) JDBC应用调优
    \nJDBC Connection Pool的调优受制于WebLogic Server线程数的设置和数据库进程数,游标的大小。通常我们在一个线程中使用一个连接,所以连接数并不是越多越好,为避免两边的资源消耗，建议设置连接池的最大值等于或者略小于线程数。同时为了减少新建连接的开销,将最小值和最大值设为一致。
    \n增加Statement Cache Size对于大量使用PreparedStatement对象的应用程序很有帮助,WebLogic能够为每一个连接缓存这些对象,此值默认为10。在保证数据库游标大小足够的前提下,可以根据需要提高Statement Cache Size。比如当你设置连接数为25,Cache Size为10时,数据库可能需要打开25*10=250个游标。不幸的是,当遇到与PreparedStatement Cache有关的应用程序错误时,你需要将Cache Size设置为0。
    \n尽管JDBC Connection Pool提供了很多高级参数,在开发模式下比较有用,但大部分在生产环境下不需调整。这里建议最好不要设置测试表, 同时Test Reserved Connections和Test Released Connections也无需勾上。 当然如果你的数据库不稳定,时断时续,你就可能需要上述的参数打开。
    \n最后提一下驱动程序类型的选择,以Oracle为例,Oracle提供thin驱动和oci驱动,从性能上来讲,oci驱动强于thin驱动,特别是大数据量的操作。但在简单的数据库操作中,性能相差不大,随着thin驱动的不断改进,这一弱势将得到弥补。而thin驱动的移植性明显强于oci驱动。所以在通常情况下建议使用thin驱动。而最新驱动器由于WebLogic server/bin目录下的类包可能不是最新的,请以Oracle网站为准: http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/htdocs/jdbc9201.html。
    \n
    \n10) JSP调优
    \n设置jsp-param pageCheckSeconds=-1；
    \n设置serlet-reload-check=-1或ServletReloadCheckSecs=-1；
    \n设置jsp-param precompile=true，关闭JSP预编译选项。

    注：在下面做的介绍都是以Weblogic8.1为例的，其它版本的Weblogic可能会有些许不同。
    \n
    \n1) 设置JAVA参数；
    \na) 编辑Weblogic Server启动脚本文件；
    \nBEA_HOME\\user_projects\\domains\\domain-name\\startWebLogic.cmd(startWebLogic.sh on Unix)  
    \nBEA_HOME\\user_projects\\domains\\domain-name\\startManagedWebLogic.cmd(startManagedWebLogic.sh on Unix) --这个是做集群的时候用的
    \nb) 编辑set JAVA_OPTIONS命令，如：set JAVA_OPTIONS=-Xms256m –Xmx256m；
    \n（在UNIX下把MEM_ARGS="-Xms1024m -Xmx1024m -Xmn128m"加到上述两个.sh文件中即可）
    \nc) 保存，重启即可。
    \n注：在WebLogic中，为了获得更好的性能，BEA公司推荐最小Java堆等于最大Java堆。
    \n（这个偶们的设置都是1024M的，反正偶们内存大大的4G呢）
    \n
    \n2) 开发模式 vs. 产品模式；
    \n开发模式和产品模式的一些参数的默认值不同，可能会对性能造成影响，下面是对性能有影响的参数列表：
    \n
    \n
    \n    
    \n        
    \n            参数
    \n            开发模式默认值
    \n            产品模式默认值
    \n        
    \n        
    \n            Execute Queue: Thread Count
    \n            15 threads
    \n            25 threads
    \n        
    \n        
    \n            JDBC Connection Pool: MaxCapacity
    \n            15 connnections
    \n            25 connections
    \n        
    \n    
    \n
    \n
    \n通过启动管理控制台，在域（如：mydomain）> 配置 > 常规选择产品模式。
    \n（这个在创建weblogic的domain的时候是有选择的，选择“产品”模式就可以了，如果后期需要修改，可以按照上面的方法修改）
    \n
    \n3) 尽量开启本地I/O；
    \n通过启动管理控制台，在域（如：mydomain）> 服务器 > server实例（如：myserver）> 配置 > 调整选择启用本地I/O。
    \n注：此值也可通过手动的修改config.xml配置文件。
    \n（这个没有试验过，不晓得有什么效果和好处，知道的告诉偶下下。）
    \n
    \n4) 调优执行队列线程；
    \na) 修改默认执行线程数
    \n在这里，执行队列的线程数表示执行队列能够同时执行的操作的数量。但此值不是设的越大越好，应该恰到好处的去设置它，太小了，执行队列中将会积累很多待处理的任务，太大了，则会消耗大量的系统资源从而影响整体的性能。在产品模式下默认为25个执行线程。
    \n（点：一般来说，其上限是每个CPU对应50个线程，其按照CPU个数线性增长.）
    \n
    \n为了设置理想的执行队列的线程数，我们可以启动管理控制台，在域（如：mydomain）> 服务器 > server实例（如：myserver）> 监视 > 性能中监控最大负载时执行队列的吞吐量和队列中的等待请求数，据此确定理想的数值。
    \n理想的默认执行线程数是由多方面的因素决定的，比如机器CPU性能、总体体系架构、I/O、操作系统的进程调度机制、JVM的线程调度机制。随着CPU个数的增加，WebLogic可以近乎线性地提高线程数。线程数越多，花费在线程切换的时间也就越多；线程数越小，CPU可能无法得到充分的利用。为获取一个理想的线程数，需要经过反复的测试。在测试中，可以以25*CPU个数为基准进行调整。当空闲线程较少，CPU利用率较低时，可以适当增加线程数的大小（每五个递增）。对于PC Server和Windows 2000，则最好每个CPU小于50个线程，以CPU利用率为90%左右为最佳。
    \n通过启动管理控制台，在域（如：mydomain）> 服务器 > server实例（如：myserver）> Execute Queue > weblogic.kernel.Defalt > 配置中修改线程计数。
    \n
    \nb) 设定执行队列的溢出条件；
    \n    Weblogic Server提供给默认的执行队列或用户自定义的执行队列自定义溢出条件的功能，当满足此溢出条件时，服务器改变其状态为“警告”状态，并且额外的再分配一些线程去处理在队列中的请求，而达到降低队列长度的目的。
    \n    通过启动管理控制台，在域（如：mydomain）> 服务器 > server实例（如：myserver）> Execute Queue > weblogic.kernel.Defalt > 配置下面几项：

    \n●线程数增加：当检测到溢出条件时，将增加到执行队列中的线程数量。如果CPU和内存不是足够的高，尽量不要改变默认值“0”。因为Weblogic一旦增加后不会自动缩减，虽然最终可能确实起到了降低请求的作用，但在将来的运行中将影响程序的性能。
    \n●最大线程数：为了防止创建过多的线程数量，可以通过设定最大的线程数进行控制。
    \n在实际的应用场景中，应根据具体情况适当的调整以上参数。

    1. 在互联网里面让一个东西火起来，聚集更多的人气并不是一件想得到做不到的事情，只要去做了效果是立杆见影的。但是我觉得一个互联网上的东西吸引人的东西只有两种：内容和服务。有些网站靠内容，如javaeye，有些网站靠服务，如自称要转向服务的IBM。而技能云，我觉得是偏向内容的，当然一个好的网站内容和服务都是不可或缺的。  
      2. \n    
    2.   
      3. \n    
    3.         技能云的初衷是好的，但是最终能不能作出预期的模样，还看当事人是否奈得住寂寞。在我看来，技能云提倡的保持程序员的一种骨子里面的骄傲，勇敢的 show，勇敢的show出真实的自己。技能云中技能的来源的基础来自于从事过的项目，而项目本身的状态是公开的，面向所有人的，受到所有人监督的，这样会起到一定的约束力。进而想通过这种约束力，形成一种公正诚信的氛围，在这种氛围中提取有价值的信息作为网站的自养之道。诚然，社会舆论和监督是一种巨大的力量。但是这对于技能云是个双刃剑，正面维护了网站内容的公正和诚信，负面隔绝了那些还需要通过通过一纸简历来养家糊口，给孩子卖奶粉的从业者。基于这点技能云不可能有太大的规模，毕竟程序员数量有限，能坦诚的交代自己的程序员就更有限了。记得几天前上技能云发现上面注册的用户的大多是些大牛，还有很大一部分是些只留下了ID，其他什么也没有留下的人。我觉得这些人也是值得我们尊敬，他们或基于现实的考虑，或受困于自身的经历，没有能在技能云上面留下什么，但是一个简单的ID表明了作为一个程序员的骄傲。  
      4. \n    
    4.   
      5. \n    
    5.             维护技能云信息的公正诚信很大一方面靠的的技能云本身提供的监督机制，而另外程序员本身的诚信。这种诚信最为可贵。古语云：诚信是金，而且在当前这种现实环境中这句话太惨白。据闻某彩票点把500W归还某代买彩票的人，一般听众的反应是：彩票点的人傻了。这就是现实。但是我想说的是技能云做的不错，在那个小的环境里面，我个人愿意相信所有的信息都是真实的。这可能就是技能云想要的氛围。而我个人的感觉也就是这种氛围影响了我。留下一个ID后就悄悄的离开的，回到自己的地方小声的吼了一下。话说，打江山不易，守江山更难。形成一种氛围固然不容易，但是要巩固它，加深它的影响自然是难上加难。虽然上面说的都很难，但是容易的事情也很容易，就是吹散这种氛围。  
      6. \n    
    6.   
      7. \n    
    7.             如何维护这种氛围，我本无发言权。但是我觉得javaeye做的很不错。一件小事情可以看出来，前不久javaeye更改了论坛的积分规则，把只要回帖就有的两分给取消了。自然，这样少了论坛的人气，但是同时也少了论坛里面的无意义内容。这符合javaeye的口号：做最棒的软件开发交流社区。正是这样的手段，隔离了那些看似的热闹，才有了javaeye上面的激烈的讨论和质量颇高的原创文章。这方面的问题，你自可以和robbin交流去，看上去他是个相当热心的人。  
      8. \n    
    8.   
      9. \n    
    9.     （BWT：我以前也在javaeye上面写Blog，可是感觉力不从心，任何一个问题似乎都没有人看的明白和透彻，看着一山又比一山高，压力实在太大，所以我就到这里来了。这里自由，写写自己看的，听的，想的，挺好。当然，我还是时不时的回去看看，毕竟那很吸引人。）  
      10. \n    
    10.   
      11. \n    
    11.         看看现在的javaeye，每天是3WIP，15W左右的PV。而技能云要做到这个现在似乎很难，但是javaeye可能很难复制了，不可能再有一个 rubyeye，perleye了。但是技能云还有这个潜力，不仅仅是程序员会对自己的工作产生自豪感，任何一个行业对有一群人狂热的爱着自己的工作。古语云：360行，行行出状元。只要技能云能够把握好自己，耐住了寂寞，维护建站的初衷和理想。可以想见：总有一天技能云会看起来像核弹引爆后的蘑菇云的。  
      12. \n    
    12.   
      13. \n    
    13.         副标题里面说这是“困惑”，这只是应景的一个说法。或许在IceskYsl心里面另有高谋。说的不好，还请IceskYsl自酌。

    \n            技能云的初衷是好的，但是最终能不能作出预期的模样，还看当事人是否奈得住寂寞。在我看来，技能云提倡的保持程序员的一种骨子里面的骄傲，勇敢的 show，勇敢的show出真实的自己。技能云中技能的来源的基础来自于从事过的项目，而项目本身的状态是公开的，面向所有人的，受到所有人监督的，这样会起到一定的约束力。进而想通过这种约束力，形成一种公正诚信的氛围，在这种氛围中提取有价值的信息作为网站的自养之道。诚然，社会舆论和监督是一种巨大的力量。但是这对于技能云是个双刃剑，正面维护了网站内容的公正和诚信，负面隔绝了那些还需要通过通过一纸简历来养家糊口，给孩子卖奶粉的从业者。基于这点技能云不可能有太大的规模，毕竟程序员数量有限，能坦诚的交代自己的程序员就更有限了。记得几天前上技能云发现上面注册的用户的大多是些大牛，还有很大一部分是些只留下了ID，其他什么也没有留下的人。我觉得这些人也是值得我们尊敬，他们或基于现实的考虑，或受困于自身的经历，没有能在技能云上面留下什么，但是一个简单的ID表明了作为一个程序员的骄傲。  
    \n      
    \n                维护技能云信息的公正诚信很大一方面靠的的技能云本身提供的监督机制，而另外程序员本身的诚信。这种诚信最为可贵。古语云：诚信是金，而且在当前这种现实环境中这句话太惨白。据闻某彩票点把500W归还某代买彩票的人，一般听众的反应是：彩票点的人傻了。这就是现实。但是我想说的是技能云做的不错，在那个小的环境里面，我个人愿意相信所有的信息都是真实的。这可能就是技能云想要的氛围。而我个人的感觉也就是这种氛围影响了我。留下一个ID后就悄悄的离开的，回到自己的地方小声的吼了一下。话说，打江山不易，守江山更难。形成一种氛围固然不容易，但是要巩固它，加深它的影响自然是难上加难。虽然上面说的都很难，但是容易的事情也很容易，就是吹散这种氛围。  
    \n      
    \n                如何维护这种氛围，我本无发言权。但是我觉得javaeye做的很不错。一件小事情可以看出来，前不久javaeye更改了论坛的积分规则，把只要回帖就有的两分给取消了。自然，这样少了论坛的人气，但是同时也少了论坛里面的无意义内容。这符合javaeye的口号：做最棒的软件开发交流社区。正是这样的手段，隔离了那些看似的热闹，才有了javaeye上面的激烈的讨论和质量颇高的原创文章。这方面的问题，你自可以和robbin交流去，看上去他是个相当热心的人。  
    \n      
    \n        （BWT：我以前也在javaeye上面写Blog，可是感觉力不从心，任何一个问题似乎都没有人看的明白和透彻，看着一山又比一山高，压力实在太大，所以我就到这里来了。这里自由，写写自己看的，听的，想的，挺好。当然，我还是时不时的回去看看，毕竟那很吸引人。）  
    \n      
    \n            看看现在的javaeye，每天是3WIP，15W左右的PV。而技能云要做到这个现在似乎很难，但是javaeye可能很难复制了，不可能再有一个 rubyeye，perleye了。但是技能云还有这个潜力，不仅仅是程序员会对自己的工作产生自豪感，任何一个行业对有一群人狂热的爱着自己的工作。古语云：360行，行行出状元。只要技能云能够把握好自己，耐住了寂寞，维护建站的初衷和理想。可以想见：总有一天技能云会看起来像核弹引爆后的蘑菇云的。  
    \n      
    \n            副标题里面说这是“困惑”，这只是应景的一个说法。或许在IceskYsl心里面另有高谋。说的不好，还请IceskYsl自酌。

    透明同学说需要给技能云一个”自动登录“的功能，于是下午睡觉起来google了些资料，也大概问了下几个朋友，思路就有了，思路很多种，这里采取的是这篇文章介绍的方式。
    \n
    基本步骤如下：
    \n
    1、首先创建一个用来保存用户信息的表modle（PersistentLogin），代码如下：
    \n
    \n
    Ruby代码
    \n
      \n    
    1. class CreatePersistentLogins < ActiveRecord::Migration  
      2. \n    
    2.   def self.up  
      3. \n    
    3.     
      4. \n    
    4.     create_table :persistent_logins do |t|  
      5. \n    
    5.       t.column :uid, :string, :null => false  
      6. \n    
    6.       t.column :user_id, :integer, :null => false  
      7. \n    
    7.       t.column :created_on, :datetime, :null => false  
      8. \n    
    8.     end  
      9. \n    
    9.           
      10. \n    
    10.     add_index :persistent_logins, :uid, :name => "uid"  
      11. \n    
    11.     add_index :persistent_logins, :created_on, :name => "created_on"      
      12. \n    
    12.       
      13. \n    
    13.   end  
      14. \n    
    14.   
      15. \n    
    15.   def self.down  
      16. \n    
    16.     drop_table :persistent_logins  
      17. \n    
    17.   end  
      18. \n    
    18. end  
      19. \n
    \n
    \n
    2、然后写这个modle，代码如下：
    \n
    \n
    Ruby代码
    \n
      \n    
    1. class PersistentLogin < ActiveRecord::Base  
      2. \n    
    2.     
      3. \n    
    3.   belongs_to :user  
      4. \n    
    4.   before_create :assign_uid  
      5. \n    
    5.     
      6. \n    
    6.   private  
      7. \n    
    7.     
      8. \n    
    8.   def assign_uid  
      9. \n    
    9.     self.uid = UUID.random_create.to_s  
      10. \n    
    10.   end  
      11. \n    
    11. end  
      12. \n
    \n
    \n
    3、紧接着在登录的页面加一个chechk_box用来供用户选择是否保存自己的信息以实现自动登录，代码如下：
    \n
    \n
    XML/HTML代码
    \n
      \n    
    1. <%=check_box_tag("persist", value = "1", checked = true, options = {})%>    记住我吧.  
      2. \n
    \n
    \n
    4、接着在你原来的验证登录的地方，添加如下代码：
    \n
    \n
    Ruby代码
    \n
      \n    
    1. # inside your 'login' code after you have validated the credentials  
      2. \n    
    2. if params[:persist]  
      3. \n    
    3.   p = PersistentLogin.create(:user=>u)  
      4. \n    
    4.   cookies[:p_session_id] = {:value => p.uid, :expires => Time.now + 7.days}  
      5. \n    
    5. end  
      6. \n
    \n
    \n
    5、写一个前置过滤器，判断用户是否存在cookie，如下：
    \n
    \n
    Ruby代码
    \n
      \n    
    1. def get_current_user  
      2. \n    
    2.   if session[:user].nil?  
      3. \n    
    3.     if cookies[:p_session_id] && p = PersistentLogin.find_by_uid(cookies[:p_session_id])  
      4. \n    
    4.       session[:user] = c_user.id  
      5. \n    
    5.     end  
      6. \n    
    6.   end  
      7. \n    
    7. end  
      8. \n
    \n
    \n
    6、最后用户点了退出登录以后，删除cookie和表中记录，代码如下：
    \n
    \n
    Ruby代码
    \n
      \n    
    1. def logout  
      2. \n    
    2.   session[:user] = nil  
      3. \n    
    3.     
      4. \n    
    4.   if cookies[:p_session_id] && p = PersistentLogin.find_by_uid(cookies[:p_session_id])  
      5. \n    
    5.     p.destroy  
      6. \n    
    6.   end  
      7. \n    
    7.   
      8. \n    
    8.   cookies.delete :p_session_id   
      9. \n    
    9. end  
      10. \n
    \n

    以前的时候只知道在Rails中建立多对多的关系可以把两个表的复数做表名，并去掉其主键ID，后来使用的过程中遇到不少问题，虽然当时也可以 hack过去了，但是心理一直觉得不爽，上次看《敏捷开发第二版》的时候，看到还有另外一个方法，刚好刚才在railscasts上也看到了，现在归纳记 录如下：
    \n
     
    \n

    多人协作的时候版本控制是很重要的，我以前公司使用的VSS或者CC&CQ，这些都是比较重量级的，做大项目的控制比较合适，但是做一些 rails的比较小的项目的时候就没有这个必要，也没有这个必要；
    \n
    相反，SVN和CVS可能更适合一点，因为CVS比较老，现在SVN比较主流，使用起来 也很方便，于是做Rails项目自然选择SVN，以前使用不多，虽然也会用，但是做了不少无用功，今天看到一篇介绍的文章，改吧改吧记录下。
    \n
    \n
    \n
    第一步，创建Rails应用并做基础设置
    \n
      \n    
    1. mkdir project //创建工程目录，在此目录下设置基础的导入数据  
      2. \n    
    2. cd project    //进入project目录  
      3. \n    
    3. rails test    //生成rails应用，名字为test  
      4. \n    
    4. cd test       //进入rails应用目录  
      5. \n    
    5. mv config/database.yml config/database_example.yml //修改数据库配置文件的名字，因为这个配置文件可能每个开发人员的都不一样  
      6. \n    
    6. rm -r log/*   //删除log目录下的所有文件，这个目录下的文件不需要加入到版本控制  
      7. \n    
    7. rm -r tmp/*   //同上，临时目录也不要加入版本控制  
      8. \n    
    8. cd ..         //回到project目录  
      9. \n    
    9. mv test trunk //修改rails应用test目录的名字为trunk，这是svn的惯例，相当与CVS的HEAD，是开发主目录  
      10. \n    
    10. mkdir tags    //惯例，保存tag  
      11. \n    
    11. mkdir branches//惯例，保存分支第二步，生成将项目文件导入SVN   
      12. \n
    \n
    \n没个项目的SVN库所使用的协议可能个不相同，这里假设你已经创建好了SVN库并可以使用了 。
    \n
    \n
    \n
    第二步：导入
    \n
      \n    
    1. cd project 在project目录下执行  
      2. \n    
    2. svn import . http://your_domain/svn/test -m "初始化导入" --username your_name  
      3. \n
    \n
    \n如果没有错误，项目就导入成功了，现在我们到自己的rails项目工作目录checkout刚刚创建的项目
    \n
    \n
    \n
    \n
    第三步：签出
    \n
      \n    
    1. cd /rails //进入你的rails工作目录  
      2. \n    
    2. svn co http://your_domain/svn/test/trunk test //checkout代码到test  
      3. \n    
    3. cd test  
      4. \n    
    4. cp config/database_example.yml config/database.yml //创建自己的数据库配置文件  
      5. \n    
    5. svn propset svn:ignore database.yml config/        //忽略database.yml文件，也就是不将此文件纳入版本控制  
      6. \n    
    6. svn propset svn:ignore "*" log/                    //忽略log下的所有文件  
      7. \n    
    7. svn propset svn:ignore "*" tmp/                    //忽略tmp目录下的所有文件  
      8. \n    
    8. svn commit -m "忽略文件"                           //提交配置好了，到现在基本的项目初始化  
      \n    
      9. \n
    \n
    \n工作即可告一段落了，以后的工作基本就是更新，编码，提交了，属于svn基本使用问题，我们就不详述了。

    \n先用content_for申明一个变量，接着可以在你需要的地方使用<%= yield :name %> 来调用，参考如上代码应该不难理解。

    做为一个安全爱好者，我可以负责任的告诉你，这些东西非常危险，恶意的人总是能想办法（这个办法很多，比如旁注等）拿到你的日志文件，而这个日志文件比起加密的数据库文件还要危险，于是肯定是需要做一些工作的。
    \n
    ActionController#filter_parameter_logging 就是我们需要的东西，它可以用来过滤那些你不想保存在日志中的数据，它可以阻止一些敏感数据赤裸裸的暴露在日志文件中，比如密码，或者信用卡帐号。也可以防止一些大块的数据占用日志文件，等等。
    \n如果你的应用用到passwords，复制下面这行到你的ApplicaitonController  Class:
    \n
    \n
    Ruby代码
    \n
      \n    
    1. filter_parameter_logging "password"  
      \n    
      2. \n
    \n
    \n
    这样就可以阻止任何匹配/password/i模式的数据被写入日志，诸如：[user][password] 或 [user][password_confirmation]
    \n
    \n另外，如果想在开发环境下显示POST logging,但是在产品环境下完全不显示，如何做呢？
    \n
    \n
    Ruby代码
    \n
      \n    
    1. filter_parameter_logging("password") if RAILS_ENV == "production"  
      \n    
      2. \n
    \n
    \n
    如果想完全禁止POST logging，则可以在production.rb中修改：config.log_level = :warn

    说来惭愧，写了这么久的Ruby，做了那么多的网站，也写过不少使用Rmagick来处理图片的代码，但是自己的机子上始终安装不成功，折腾了好几 次，我记得都没有最终完全搞定。本来准备使用Ubuntu上，但是很多东西在Win下使用惯了，所以还是安心的在WIN下做开发吧。
    \n
    言归正传，说说怎么在Win下安装Rmagick，其他的部分可以参考http://www.javaeye.com/post/167758和 http://blog.sina.com.cn/s/blog_4a6ae9750100076w.html这两文章，我大概说下步骤和可能会出现的问 题，记录一下：
    \n
    1、首先到这个地方去下载RMagick的最新Windows版本，到目前为止的最新版本是rmagick-win32-1.13.0_IM-6.2.9-3.zip。
    \n
    2、先解压，然后输入命令安装：gem install rmagick-1.13.0-win32.gem
    \n
    3、然后再点ImageMagick-6.2.9-3-Q8-windows-dll.exe安装，并且把这个的安装路径放到path环境变量里面去，否则会出现CORE_RL_magick_.dll找不到的错误（需要注意，加入后CMD需要重新打开下，否则不行）。
    \n然后试试这段代码，如下：
    \n
    \n
    示例代码
    \n
      \n    
    1. require 'RMagick'  
      2. \n    
    2. include Magick

    \n一眼看出问题所在，user_id这个字段保存的才是用户的ID，而前面那段代码取成了id 字段，真是疏忽呀～
    \n
    找到问题，自然好解决了，不在废话～

    \n
      \n    
    • 速度偏爱
      • \n    
      在大多数情况下，偏爱节拍速度较快的音乐（BPM ”Beat per Minute”>80）。在歌曲节奏性与旋律性的对比上，你更倾向于节奏性较强的音乐表达和充满能量的速度感体验。
      \n    
    • 歌词偏爱
      • \n    
      简单直接，甚至带有一些无所谓何般抵抗的词汇才是脑中所想，反叛性的歌词亦是这类听者的最爱“我不愿相信真的有魔鬼,也不愿与任何人作对”，“噢姐 姐，我想回家，牵着我的手，我有些困了……”。“你会看见雾、看见云、看见太阳，纪念和大地重复着悲伤……”你完全不喜欢千篇一律的情感描述词句。
      \n    
    • 歌曲情绪体现
      • \n    
      在你看来，情绪表达是一首歌的重要内容之一。你会十分在意一首歌的情绪是否与你心情合拍，并倾向于较为直接和激烈的情绪表达。
      \n    
    • 人声体现
      • \n    
      喜欢不一样的声音，喜欢嗓子里像粘上碎玻璃的声音；喜欢人声随着乐器越来越猛烈的嘶喊，混乱、躁动，不安现状的声音会得到青睐；不喜欢做作和感情扭捏造作的口水式演唱。
      \n    
    • 曲风偏好
      • \n    
      在纷繁的音乐类型中，这种类型的爱好者会偏爱硬摇滚、另类、朋克（PUNK）、重金属Heavy metal、流行金属等能量较高的音乐。
      \n    
    • 乐器偏好
      • \n    
      偏爱电声乐器（什么是？）：如失真电吉他、电贝司、架子鼓、饱满的木吉他扫弦或是一段精彩的乐器SOLO（什么是？）中那充满延伸的电子合成器；喜欢原始却不失热情的配器，
      \n    
    • 能量消耗
      • \n    
      无论从演奏者还是演唱者，都会有极度消耗能量的倾向，而这样的倾向，会获得典型此类型人的极大共鸣

    Google放出来的AJAX feed API我老早就关注到了，也试用了一些，感觉还真的不错，现在又添加了一些东西，如下：
    \n其API都很简单，详细的可以看这个页面上的介绍：
    \nhttp://code.google.com/apis/ajaxfeeds/documentation/reference.html#FeedControl
    \n只有一个构造器：FeedControl
    \n四个函数：
    \n1.addFeed(url, label) //添加需要显示的FEED的URL
    \n2.addFeed(element, opt_options?)；//这个其实就是draw方法，指定显示的方式，例如：
    \n\n
    feedControl.draw(
    \ndocument.getElementById("feedControl"),
    \n{
    \ndrawMode : google.feeds.FeedControl.DRAW_MODE_TABBED
    \n});
    \n\n
    feedControl这个是页面的DOM的ID名称，google.feeds.FeedControl.DRAW_MODE_TABBED 就是指定的显示方式，默认值是：google.feeds.FeedControl.DRAW_MODE_LINEAR.
    \n\n
    3.setNumEntries(num)； //设定显示的条数（貌似只能统一指定，不能为各个FEED单独指定）
    \n4.setLinkTarget(linkTarget) //设定链接的打开方式，其值分别如下：
    \n\n
      \n
    • google.feeds.LINK_TARGET_BLANK - links will open in a new window
      • \n
    • google.feeds.LINK_TARGET_SELF - links will open in the current window
      • \n
    • google.feeds.LINK_TARGET_TOP - links will open in the topmost frame
      • \n
    • google.feeds.LINK_TARGET_PARENT - links will open in either the topmost frame, or replace the current frame.
      • \n
    • anything-else - the value of target in the resulting anchor element is set to linkTarget
      • \n
    \n\n
    附录其网站上的说明：
    \n\n
    This morning we added a new class to the Google AJAX Feed API designed to allow you to more easily add a collection of feeds to your pages. The FeedControl is pretty simple:
    \n\n
    var feedControl = new google.feeds.FeedControl();
    \nfeedControl.addFeed("http://www.digg.com/rss/index.xml", "Digg");
    \nfeedControl.addFeed("http://feeds.feedburner.com/Techcrunch", "TechCrunch");
    \nfeedControl.draw(document.getElementById("feedControl"));
    \n\n
    In addition to the formal documentation, we have put together a few samples to help you quickly come up to speed.
    \n
    \n    Basic FeedControl - feedcontrol.html
    \n    Tabbed FeedControl - tabbed.html
    \n    Sidebar Style FeedControl - sidebar.html

    在infoQ上看到一篇关于软件构架的文章，说了一个软件构架中可能存在的一些错误，有些错误在现有的软件，项目构架中是普遍存在的问题，转载记录一二。

    虽然我不是构架师，但是在做RoR项目的时候，这些角色都是混杂起来的，必须是全部了解，因为没有那么多的空闲资源，所以了解还是很有必要的。

    原文开始：
    \n
    IASA成员Eoin Woods发表了一篇文章讲述他所认为的十大软件架构错误——常常要碰得头破血流才会得到的一些教训。这十大错误简要总结如下：
    \n
      \n    
    1. 不能界定项目范围。“在这种情况发生时，一个简单的出差登记系统结果变成内建了完整的花费报销管理系统，项目费用、时间跨度和质量都留下不可避免的烂摊子……除了简单的登录真的不需要安全措施了？用户登录系统后真的不能够执行任何系统操作吗？”
      2. \n    
    2. 网撒得不够宽。“我们都曾经犯过的一个错误是，只关注系统所有利益相关者中的一两方——通常受让人（为系统出钱的人）和最终用户得到了全部的关注。”
      3. \n    
    3. 只关注功能。“……除非系统表现出了全面的高质量（诸如性能、安全、可维护性等等），否则不太可能成功。”
      4. \n    
    4. 用方框和线条来描述。“[一个无所不包的]巨大的Visio图无法成为有效的架构描述，有两个原因：第一，它试图在单一表示中呈现太多信息；第二，没人真正清楚地知道你画的各种符号到底表示什么意思。”
      5. \n    
    5. 忘了需要培养的过程。“在建造系统的时候常常需要小心的事物包括：开发者和测试者没法真正理解设计，他们不热衷或者没时间学习技术，以及还没有很好的工具支持的新技术，或者新技术会强迫人们以新的不熟悉的方式工作。”
      6. \n    
    6. 平台定义不精确。“光用‘需要Unix和Oracle’来描述你的平台是不足够的。你需要精确地说明每一部分具体的版本和配置，才能保证得到你所需的平台。不然如果有人好心为平台的某一部分升级了一个库，就可能导致某些东西停止运作。精确定义平台你才能在部署中避免这样的情形。”
      7. \n    
    7. 对性能和伸缩能力想当然。“及早开始考虑性能和伸缩性，构建性能模型尝试预测关键的性能指标并定位瓶颈，在设计逐渐成型的同时投入到一些实际的验证性工作中去。这会帮助你提高对设计中不存在严重性能和伸缩性缺陷的信心。”
      8. \n    
    8. 自己发明安全技术。“多 年来许多系统所犯的一个错误是试图加入自己发明的安全技术来提高系统安全性。比如定制的加密算法，开发者自己编写的审核系统，甚至完全DIY的访问控制系 统。自家开发的安全方案基本上都是不明智的。虽然很多人都以为自己可以马上搞出一些聪明的安全技术，但通常都只是自作聪明。”
      9. \n    
    9. 没有灾难恢复。“要想得到资源来实现系统的灾难恢复机制，其关键在于在若干真实的场景中，具体衡量系统不可用所导致的损失。如果你还能估算这些场景发生的概率，你就可以用这两组数据去说服人们灾难恢复的重要性，并获得合理的预算去实现它。”
      10. \n    
    10. 没有撤退计划。“确保无论在系统部署或升级的过程中发生任何事，你都有一份书面的、经过审查的、一致同意的撤退计划，允许你将整个环境恢复到部署之前的状态。”

    \n
    社区Architecture,Ruby
    主题Web 2.0,Ruby on Rails
    \n
    编者按：因 为Ruby on Rails的出现，借用互联网创业的人越来越多，虽然不能说全是RoR的功劳，但至少说明技术门槛的降低加速了互联网的发展。从前从一个点子的产生到实现 可能要耗费少则几个月，多则几年的时间，而现在，只要你的点子够新，有实践的可能，几天几周就可以看到原型。而后面的维护也比较方便，几乎可以说是实时进 行。本文通过采访技能云网站的策划人熊节和主设计师Iceskysl就是想证明前文所述，据两人介绍，这两个到现在还没有见过面的年轻人通过网络，在不到两周的时间里，将一个创意点子变成了现实。
    \n
    InfoQ中文站：这个项目发布后，你被人问到的最多的三个问题是什么？
    \n
    InfoQ中文站：介绍一下你自己和你的团队？ 
    \n
    IceskYsl：我是IceskYsl，目前还是靠Java吃饭，ROR是暂时还是业余活动，很享受这种方 式；1sters!暂时还是个虚拟的、我自己心中理想中的团队模式，也正一步步的走向成熟。我接触RoR有一段时间了，期间被它的灵活吸引，有事没事的就 会写写代码，时间不多，写了好几个像模像样的系统如：
    \n
      \n    
    1. byeloo.cn（毕业咯）：一个开源的多班级同学录系统，趴在床上用笔画出大概的模块以及基本的数据结构后；利用一个通宵写完了整个框架，而后就上线使用，根据同学们的要求，主键完善。目前功能都很实用；
      2. \n    
    2. 然后是1stlog，一个针对国内用户的基于ROR的blog程序，功能强大可定制，方便扩展，已经发布两个版本，马上即将发布第三个版本；
      3. \n    
    3. 1sters.com：一个集新闻，产品展示，官方blog，已经产品缺陷跟踪管理于一体的CMS系统；
      4. \n    
    4. 1stimes：第一次是一个分享你我第一次经历的Web 2.0的系统；
      5. \n    
    5. itechtag：技能云。
      6. \n
    \n
    熊节：我是熊节，网名叫"透明"的。先后干过媒体、程序员、咨询师三种职业，所以有一堆Web 2.0的点子。可惜每天忙忙叨叨的，这些点子落地的很少。

    InfoQ中文站：技能云的创意是从何而来？
    \n
    IceskYsl：项目的创意随着时间逐步演化，起初只是为程序员及其相关的人提供一个展现自我的平台，为国内的程序员赢得更多的他曾被无形剥夺的东西；进而发展为项目展示、交流、经验分享及其人脉的一个平台。
    \n
    熊节：这个东西的想法很简单：我要有一个widget挂 在我的blog上，告诉别人我有些什么技能，譬如说我Ruby很不错、Java很不错、JavaScript也有经验，等等。为什么我想给别人show这 些呢？因为我觉得骄傲，为自己骄傲。我在过去的8年里一直在编程，我掌握了那么多的技能，我觉得很骄傲。说白了就是，我要向别人炫耀自己的技能。
    \n
    东西很简单，但背后可以有引申。这个炫耀的widget一展开，就引出了别的东西，那就是从哪里得到这些技能的信息。当然了，只有从项目经验里来。 只有真正在项目里做过，用过一种技术，你才能说你掌握了这种技能。而且一般来说，技能掌握的熟练程度还是和使用的时间成正比的。所以iTechTag是以 项目为基础的。你不能说自己"精通"、"熟练掌握"什么技能，你必须证明，证据就是真实的项目经验。
    \n
    那么有了一个炫耀的widget，有了一堆项目经验，就可以很方便的导出简历了。（这是我们下一步的重点功能。）技能－经验－简历，这个三位一体就 构成了一个程序员的声望（reputation）。谁对这些声望感兴趣呢？当然是正在招人的潜在雇主。换句话说iTechTag的注册用户在炫耀的同时顺 手得到了直接面对潜在雇主的机会。这就是我一开始说的，“释放程序员声望的价值”。如果说开源软件是把源代码的价值还给程序员（和用户），那么 iTechTag这个模式就像是人才招聘领域的开源，把程序员的价值还给程序员（和潜在雇主）。

    本文是infoQ中文站的采访帖，版权归infoQ所有，如需要查看原文，请到这里：
    \n作者          霍泰稳          发布于           2007年10月17日 上午3时7分
    \n社区Architecture,Ruby主题Web 2.0,Ruby on Rails
    \n编者按：因 为Ruby on Rails的出现，借用互联网创业的人越来越多，虽然不能说全是RoR的功劳，但至少说明技术门槛的降低加速了互联网的发展。从前从一个点子的产生到实现 可能要耗费少则几个月，多则几年的时间，而现在，只要你的点子够新，有实践的可能，几天几周就可以看到原型。而后面的维护也比较方便，几乎可以说是实时进 行。本文通过采访技能云网站的策划人熊节和主设计师Iceskysl就是想证明前文所述，据两人介绍，这两个到现在还没有见过面的年轻人通过网络，在不到两周的时间里，将一个创意点子变成了现实。
    \nInfoQ中文站：这个项目发布后，你被人问到的最多的三个问题是什么？
    \nInfoQ中文站：介绍一下你自己和你的团队？ 
    \nIceskYsl：我是IceskYsl，目前还是靠Java吃饭，ROR是暂时还是业余活动，很享受这种方 式；1sters!暂时还是个虚拟的、我自己心中理想中的团队模式，也正一步步的走向成熟。我接触RoR有一段时间了，期间被它的灵活吸引，有事没事的就 会写写代码，时间不多，写了好几个像模像样的系统如：
    \n
    \n    byeloo.cn（毕业咯）：一个开源的多班级同学录系统，趴在床上用笔画出大概的模块以及基本的数据结构后；利用一个通宵写完了整个框架，而后就上线使用，根据同学们的要求，主键完善。目前功能都很实用；
    \n    然后是1stlog，一个针对国内用户的基于ROR的blog程序，功能强大可定制，方便扩展，已经发布两个版本，马上即将发布第三个版本；
    \n    1sters.com：一个集新闻，产品展示，官方blog，已经产品缺陷跟踪管理于一体的CMS系统；
    \n    1stimes：第一次是一个分享你我第一次经历的Web 2.0的系统；
    \n    itechtag：技能云。
    \n
    \n熊节：我是熊节，网名叫"透明"的。先后干过媒体、程序员、咨询师三种职业，所以有一堆Web 2.0的点子。可惜每天忙忙叨叨的，这些点子落地的很少。
    \nInfoQ中文站：技能云的创意是从何而来？
    \nIceskYsl：项目的创意随着时间逐步演化，起初只是为程序员及其相关的人提供一个展现自我的平台，为国内的程序员赢得更多的他曾被无形剥夺的东西；进而发展为项目展示、交流、经验分享及其人脉的一个平台。

    \n
    方法很简单：rake rails:freeze:gems等几个命令就ok，会把rails单独拷贝到你的 vender下，而rails启动的时候先看这个目录，如果有就加载，没有的话再加载系统的。

    至于为什么这么做，你可以参考他写的文章：http://support.tigertech.net/freeze-rails

    晕，哪里出问题了呢？我刚才没有更新代码上去呀，看来是系统的问题，SSH上去，看日志没有任何有用的信息，调试一把，可以启动，难道是 sessions的问题（我的session还是保存在文件系统里面的），转到tmp/sessions下wc -l 了一下，寒，7W多个文件，恐怖，貌似我忘记清理了，直接rm * （保存密码的人别骂我哈），显示参数过长，郁闷，看来文件数太多了，文件貌似也没有什么规律，总不能一个一个删吧（傻瓜才这个干），于是寻找解决办法。

    \n按照作者给出的用法，如下：
    \n
    It can be run with 2 optional parameters: “atime”, which defines the time in minutes that will be compared against the last access time of a session file and “ctime” which defines the time in minutes that will be compared against the creation time of a session file. The default values are: ctime = 120 (minutes) and atime = 20 (miuntes) which means that the session files not accessed in the last 20 minutes and created earlier than 2 hours ago will be removed when the script runs.
    \n
    保存到你的lib/tasks目录下，然后用rake -T就可以看到这个rake命令，可以接受两个参数，举个例子，如下：
    \n
    \n
    \n
    Ruby代码
    \n
      \n    
    1. rake tmp:sessions:clear_expired atime=15 ctime=60  
      2. \n
    \n
    \n另外，还google到一段直接配置的脚本，如下：
    \n
    Here's a cron-only one liner which, every 30 min, removes all session files that haven't been accessed in 4 hours.  10,40 * * * * /usr/bin/find /u/apps/*/current/tmp/sessions -name "ruby_sess*" -amin +240 -exec rm {} \\;

    当使用了svn版本控制系统后每个目录下都会有一个.svn目录存在，开发完当交付产品或者上传到服务器时一般要把这些目录删除，这里总结了一下在linux和win下的办法。
    \n
    一、在linux下
    \n
    删除这些目录是很简单的，命令如下
    \n
    \nfind . -type d -name ".svn"|xargs rm -rf
    \n
    或者
    \n
    find . -type d -iname ".svn" -exec rm -rf {} \\;  
    \n
    全部搞定。(http://tech.techweb.com.cn/redirect.php?fid=26&tid=205673&goto=nextnewset)
    \n
     
    \n
    二、在windows下用以下法子：
    \n
    1、在项目平级的目录，执行dos命令： 
    \nxcopy project_dir project_dir_1 /s /i
    \n
     
    \n
    2、或者在项目根目录执行以下dos命令 
    \nfor /r . %%a in (.) do @if exist "%%a\\.svn" rd /s /q "%%a\\.svn"
    \n
    其实第二种方法可以用来干很多事的，比如把代码中的.svn替换为任意其他文件名并在硬盘根目录下执行，就可以从硬盘上删除所有的这个文件啦。
    \n
    3、加注册表
    \n
    Jon Galloway提供了一段注册表代码，可以将”Delete SVN Folders”命名增加到资源管理器的右键上，这样，鼠标点两下就能把选中目录下的所有.svn目录干掉了。Works just great!
    \n
    代码为：
    \n``Windows Registry Editor Version 5.00

    [HKEY_LOCAL_MACHINE\\SOFTWARE\\Classes\\Folder\\shell\\DeleteSVN]@=”Delete SVN Folders“

    [HKEY_LOCAL_MACHINE\\SOFTWARE\\Classes\\Folder\\shell\\DeleteSVN\\command]@=”cmd.exe /c \\”TITLE Removing SVN Folders in %1 && COLOR 9A && FOR /r \\”%1\\” %%f IN (.svn) DO RD /s /q \\”%%f\\” \\”“```\n
    将这段代码保存为一个.reg文件，双击确认导入注册表即可。

    \n其实第二种方法可以用来干很多事的，比如把代码中的.svn替换为任意其他文件名并在硬盘根目录下执行，就可以从硬盘上删除所有的这个文件啦。
    \n3、加注册表
    \nJon Galloway提供了一段注册表代码，可以将”Delete SVN Folders”命名增加到资源管理器的右键上，这样，鼠标点两下就能把选中目录下的所有.svn目录干掉了。Works just great!
    \n代码为：
    \nWindows Registry Editor Version 5.00<br /><br />[HKEY_LOCAL_MACHINE\\SOFTWARE\\Classes\\Folder\\shell\\DeleteSVN]@=&rdquo;<span style="color: rgb(139, 0, 0);">Delete SVN Folders</span>&ldquo;<br /><br />[HKEY_LOCAL_MACHINE\\SOFTWARE\\Classes\\Folder\\shell\\DeleteSVN\\command]@=&rdquo;<span style="color: rgb(139, 0, 0);">cmd.exe /c \\&rdquo;TITLE Removing SVN Folders in %1 &amp;&amp; COLOR 9A &amp;&amp; FOR /r \\&rdquo;%1\\&rdquo; %%f IN (.svn) DO RD /s /q \\&rdquo;%%f\\&rdquo; \\&rdquo;</span>&ldquo;`
    \n将这段代码保存为一个.reg文件，双击确认导入注册表即可。

    \n         scrot -cd 10 ~/abc.png
    \n
    \n5、生成缩略图，t 表示要生成缩略图， 20% 表示缩略图的比例， s 表示截取用户划定区域：
    \n         scrot -t 20% -s ~/abc.png
    \n
    \n6、启用某项操作 s 划定截图，-e 采用某项行为，这里用 gimp 打开截图图片，

    \n等到网站有第一批用户，为了牢牢抓住他们，及利用他们带更多用户 进来，必须更加揣摩他们的心思甚或社交习惯。结果更深化了这样的 发展，更加走向某一种文化氛围或者社会阶层，再也无法回头。

    I ported the php code for open flash chart to ruby and so far it has worked quite well with Rails. Just ported the latest 1.9.6 version – see the many graph examples below. To install and use the open flash chart plugin for Rails do the following:
    \n
    \n
      \n    
    1. script/plugin install http://svn.pullmonkey.com/plugins/trunk/open_flash_chart/
      2. \n    
    2. Move the open_flash_chart.swf file into your RAILS_ROOT/public directory
      3. \n    
    3. Create a controller and a view as in my examples below.
      4. \n

    \n
    升级前，版本如下：
    \n
    iceskysl@IceskYsl:~$ gem -v
    \n0.93
    \niceskysl@IceskYsl:~$ rails -v
    \nRails 1.2.5

    2. iceskysl@IceskYsl:~$ gem update rails --include-dependencies   
      3. \n

    \n升级完，看下版本
    \niceskysl@IceskYsl:~$ gem -v: 1.0.1
    \niceskysl@IceskYsl:~$ rails -v
    \n
    出现rubygems.rb:379:in `report_activate_error': RubyG
    \nem version error: activesupport(1.4.2 not = 2.0.2) (Gem::LoadError)错误，看来有点问题。
    \n
    紧接着执行：gem update activesupport即可。
    \n
    2、出现View的问题

    3、插件问题
    \n    
    类似auto_complete_for这个不在包含在Rails核心中，而是以插件的发布，需要安装一下，如下：

    \n从上面的作物日志可以看到，是调用callbacks_for的时候出的问题，而我当时使用的attachment_fu是比较老的版本，作者在后面更新过一次，于是：
    \n
    1、首先更新版本，发现依然无法使用，还是类似的错误
    \n
    2、在COR上发个帖子，大家都说自己的rmagick没有问题，奇怪的很。
    \n
    3、Google下，找到有人遇到类似问题，如下：
    \n\n
    而上面两个地址都给了另外一个页面的链接地址“Edge callback refactorings && attachment_fu" ,看来找到问题了，在其页面上说到：\n

    详细的你可以参考这个页面，我就不多说了，下面主要说说怎么解决。

    Ruby代码
    \n
      \n

    春节回家时，在逛街的时候，才买了4个月的手机丢了（联想i908），回来后第一件事情就是再选一款合适的手机，说实在的，选手机我真不是行家，上次买i908的时候就选了好久，最后还是买贵了不少，呵呵。这次按照我的需要关注了如下几个手机。
    \n
    一、个人需求
    \n
    个人对手机的需求不是很赶“潮流”，认为够用就可以了，价格自然是越低越好，第一次用的是联想的i716，折叠的，而后就是丢掉的i908，直板的。目前认为直板的比较方便，不喜欢滑盖的。喜欢简约大气的类型，不喜欢花里胡哨的。
    \n
    个人喜欢在坐公交车的时候看看电子书（以前就是把PDF转成TXT直接看了不少技术文档）或者做些行程规划、事务处理（最好是联网的，以前手机不支持，非常喜欢这个功能），处理电子邮件（用的是Gmail，需要只是SSL和XHTML，以前的i908就不支持）。最好是有个拍照功能，喜欢随手拍些东西。最好有音乐功能（这两个貌似一般手机都支持了）。
    \n
    我还是比较看重手机品牌的，联想的我用过两个，质量还行，诺基亚的市场份额说明其质量不错。
    \n
    二、筛选过程
    \n
    1、联想i908
    \n
     
    \n
    \"\"
    \n
    最先看的是丢掉的那款，联想i908，我买的时候是1500多，现在商场报价大概在1100左右，网络报价有的只有900的样子，价格降了不少。加上我还剩余其配件（电板一块，耳机，充电器啥的都还在），选择这款的原因是这些配件不会浪费掉（因为都还比较新，浪费了实在可惜）。
    \n
    2、诺基亚N70
    \n
    \"\"
    \n
    这款机子我哥哥在用，试了下还是不错的，布局和功能都基本符合我的需求，且是一款智能手机（虽然不晓得用到的有多少，有朋友说 智能只是玩具，呵呵），价格大概在1700的样子，性价比还是挺不错的，
    \n
    3、诺基亚N73
    \n
    \"\"
    \n
    这款机子应该是很经典的啦，号称街机王，目前报价应该是2K以上，功能相当强大，也是一款智能手机。虽然上市有一段时间了，但是依然相当火爆。
    \n
    4、诺基亚 5310 XpressMusic
    \n
    \"\"
    \n
    这个手机我昨天在卖场看了下，商场给的价格还是2K以上，不过网上已经给出1900的价格，可是感觉太薄了，容易丢失。
    \n
    5、联想i909
    \n
    \"\"
    \n
    这个和i908差不多，估计原来的电池啥的还可以使用，屏幕大小也差不多，但是其定位是在“游戏手机”，我玩的不多。
    \n
    6、联想i968
    \n
    \"\"
    \n
    号称可以和N73相抗衡的手机，但是那个 蓝色的颜色我不是很喜欢。
    \n
    7、iphone
    \n
    \"\"
    \n
    这个只有看看的份，比较贵，且对其中文支持不放心，我不是mac迷，呵呵。
    \n
    其他的都还没来得及看，也没没有最终确定，有谁使用过如上手机的，说说感受哈，也希望能有人推荐其他的哈。

    \n
    先来看这篇文章“How To Manage Your Online Reputation”，文章中说到：You've spent a lot of time building up your reputation and image both online and off, so it's important to make sure that someone isn't out there dragging it through the mud. The latest tool for reputation management is Trackur, but its bottom-level price is $88/month, so the question on my mind, is: "Is it worth it?" There are already many different ways to monitor your online reputation as it is. Let's see how they stack up. 
    \n
    而后列举了几个可以使用的工具（网站）来管理自己的在线声望，其中提到了一个网站http://www.trackur.com/竟然是收费的，而且还不便宜，最便宜的还88美刀/月，另外还有像google通知等。详细的可以去看这篇文章：http://www.readwriteweb.com/archives/how_to_manage_your_online_reputation.php
    \n
    接着看上面说到的这个收费的网站，真的是个监视、管理个人在线声望的网站，价格也真不便宜，呵呵，看看他是怎么说个人声望的：
    \n
    Did you know that 52% of individuals put their trust in what others have to say about you?
    \n
    \nDid you know that 87% of consumers look at the reputation of your CEO, when judging your company's reputation?
    \n
    \nDid you know that 59% of hiring managers are influenced by your online reputation?
    \n
    \nDid you know that Trackur will monitor the web 24/7 and alert you whenever your reputation is being discussed?( 这条是宣传自己网站的）
    \n
    看看上面列举的几个数据，怎么来的，我们无法得知，但是其在一定程度上说明了个人声望是如何的重要，可能国外会更普及一点；但是对于国内来说，其他行业我不了解，至少和互联网沾边的，不如软件开发行业等，会比较看重的。
    \n
    都说国内什么都要落后老外们几年时间，但是值得我们高兴的事，我们这次我们的意识并没有晚，我们与2007年中开始做的”技能云“正是在这个方面的体现，我们希望的是通过用户的努力，创建良好的个人声望，并勇敢的把自己的声望show出去；此外，我们还将创建公司和项目的声望。
    \n
    虽然我们才刚刚起步，虽然很多人还不能意识到这点的重要性，但是我们相信，随着时间的推移，随着个人不断的体会和经历，加上技能云平台的不断完善，我们肯定会让所有的对自己声望在意的朋友建立起自己的”技能云“。

    转义正则表达式中的特殊字符
    \n===========================================
    \n使用Regexp.escape方法(别名方法是Regexp.quote)，可以把正则表达式中的特殊字符统统转义：
    \nstr1 = "[*?]"
    \nstr2 = Regexp.escape(str1)    # "\\[\\*\\?\\]"
    \n
    \nescape会转义掉[*?]这几个特殊的字符，但是其没有对另外一个字符‘/’进行任何处理，这个作为正则表达式的分隔符(//)中的字符难道不是特殊字符么。
    \n
    \n 看个例子：
    \npages="http://www.taojer.com/id=1&name=help"
    \nputs Regexp.escape(pages)
    \n
    \n 输出：
    \nE:\\Ysl\\Test>ruby exp.rb
    \nhttp://www\\.taojer\\.com/id=1&name=help
    \n
    \n可以看到其对/字符是没有进行处理的。
    \n
    \n这个可能会给如下这个需求带来一些问题：
    \n我想在一段String中找到所有以一个指定的URL开头的链接地址，程序大概是这样的：
    \nurl="http://www.taojer.com"
    \n按照我们的思路，可能会这么写：

    转义正则表达式中的特殊字符
    \n===========================================
    \n使用Regexp.escape方法(别名方法是Regexp.quote)，可以把正则表达式中的特殊字符统统转义：
    \nstr1 = "[?]"
    \nstr2 = Regexp.escape(str1)    # "[    \\?]"
    \n
    \nescape会转义掉[*?]这几个特殊的字符，但是其没有对另外一个字符‘/’进行任何处理，这个作为正则表达式的分隔符(//)中的字符难道不是特殊字符么。
    \n
    \n 看个例子：
    \npages="http://www.taojer.com/id=1&name=help;"
    \nputs Regexp.escape(pages)
    \n
    \n 输出：
    \nE:\\Ysl\\Test>ruby exp.rb
    \nhttp://www.taojer.com/id=1&name=help
    \n
    \n可以看到其对/字符是没有进行处理的。
    \n
    \n这个可能会给如下这个需求带来一些问题：
    \n我想在一段String中找到所有以一个指定的URL开头的链接地址，程序大概是这样的：
    \nurl="http://www.taojer.com"
    \n按照我们的思路，可能会这么写：
    \ne_url = Regexp.escape(url)
    \n==》http://www.taojer.com
    \nstr.scan(/<a href="(e_url)">(.+?)<\\/a>/m)
    \n但是这样就会因为/字符存在而异常咯？
    \n
    \n正确是应该是：
    \nstr.scan(/<a href="(http:\\/\\/www.taojer.com)">(.+?)<\\/a>/m).each do |list|
    \n\n
    do something

    问题：
    \n我在rails中使用fasterCSV导出DB里面的东西，编码为UTF-8,在linux上查看一切正常，但是我先后采用了zip，gzip，tar，7zip，rar，以及biz等压缩后传送给windows，打开发现是乱码。
    \n
    具体表现为：
    \n
    1、zip，tar，gzip，biz等压缩出来的，中文文件名和数据文件均乱码;

    在linux与windows平台间交换压缩包文件，如果文件名中含有中文，有时候就会遇到乱码问题，给平台间的文件交换带来麻烦。今天仔细研究了一下，总结下面一些经验，供大家分享
    \n
    1. 7zip和rar（我用的是3.50，好像rar的旧版本不行）会对文件名编码进行转换，内部文件名编码使用
    \n
    unicode，所以使用这两种格式在linux和windows平台间交换不会有乱码问题，其他格式（比如tar.gz, tar.bz2)似乎不进行转换，所以不适合平台间交换。但鉴于linux的自由精神，不推荐使用商业软件rar，而推荐自由的7zip。但是，我发现用 Ubuntu中（我的是Edge）file-roller处理7zip文件还是会存在问题，而用命令行就没有问题，所以推荐大家用命令行的7zip。
    \n

    \n按照找到的资料，应该只有文件名会出现乱码，正文内容不会乱码的呀，真是奇怪。

    \n
    先看如果压缩文件,看代码,如下:
    \n
    \n
    \n
    Ruby代码
    \n
      \n    
    1. pwd = Dir.pwd  
      2. \n    
    2. logger.info("Dir.pwd=\#{pwd}")  
      3. \n    
    3. Dir.chdir("\#{cp_dir}") do  
      4. \n    
    4.   system "rar a  \#{local_dir_name} \#{local_dir_name}"  
      5. \n    
    5. end   
      6. \n
    \n
    \n
    \n
    使用了Ruby的Dir及其代码块的临时切换目录的功能,实在是棒,开始的时候,我还在想使用Tar或者rar用-C参数来去掉打包后的文件夹路径;
    \n
    至于这里为什么使用rar而没有使用比较传统的tar或者gzip,zip或则7zip等,主要是乱码的问题,详细的大家可以查看我以前的文章<linux和windows之间的压缩包乱码>.
    \n
    而后下载的过程中,再次感觉WIn下IE的可恶,乱码,呵呵,没关系,我们可以这样做,如下: 
    \n
    \n
    Ruby代码
    \n
      \n    
    1. res = Resource.find(params[:id])  
      2. \n    
    2. res.update_attribute(:downed_count, res.downed_count + 1)  
      3. \n    
    3. user_agent = request.user_agent.downcase  
      4. \n    
    4. filename = File.basename(res.path)  
      5. \n    
    5. if user_agent  =~ /msie/i  
      6. \n    
    6.   send_file(RAILS_ROOT + res.path,:buffer =>  
      7. \n    
    7.       "16384",:filename=>CGI::escape(filename))  
      8. \n

    由于项目需求,用户可以定制,下载一些数据和图片,于是乎就需要实现的功能有:打包,中文,以及下载等,这里大概的说一下,我也是测试了好久,查了好多资料踩搞明白一些问题,首先BS下window所谓的国际化.真是FT.
    \n先看如果压缩文件,看代码,如下:
    \n
    \n
    \nRuby代码
    \n
    \n    pwd = Dir.pwd  
    \n    logger.info("Dir.pwd=\#{pwd}")  
    \n    Dir.chdir("\#{cp_dir}") do  
    \n      system "rar a  \#{local_dir_name} \#{local_dir_name}"  
    \n    end   
    \n
    \n
    \n
    \n使用了Ruby的Dir及其代码块的临时切换目录的功能,实在是棒,开始的时候,我还在想使用Tar或者rar用-C参数来去掉打包后的文件夹路径;
    \n至于这里为什么使用rar而没有使用比较传统的tar或者gzip,zip或则7zip等,主要是乱码的问题,详细的大家可以查看我以前的文章<linux和windows之间的压缩包乱码>.
    \n而后下载的过程中,再次感觉WIn下IE的可恶,乱码,呵呵,没关系,我们可以这样做,如下: 
    \n
    \nRuby代码
    \n
    \n    res = Resource.find(params[:id])  
    \n    res.update_attribute(:downed_count, res.downed_count + 1)  
    \n    user_agent = request.user_agent.downcase  
    \n    filename = File.basename(res.path)  
    \n    if user_agent  =~ /msie/i  
    \n      send_file(RAILS_ROOT + res.path,:buffer =>  
    \n          "16384",:filename=>CGI::escape(filename))  
    \n    else  
    \n      send_file(RAILS_ROOT + res.path,:buffer => "16384")  
    \n    end

    这几天，项目上遇到一个很奇怪的问题，由于项目比较庞大，使用了3台独立的主机做服务器，前端用了硬件的radware采用轮询算法做了三台服务器的负载均衡，每台服务上部署了一台weblogic和一个前置apache做proxy，并且启用了apache的支持weblogic的集群功能，二次向三台weblogic做负载均衡（虽然这里我觉得没啥必要，但是原先他们就这么做了，我就不改了）。
    \n
    apache使用的是prefork模块，开了800个最大连接，配置了超时机制；后端的weblogic除了线程池和队列，文件句柄等做了修改外，其他的貌似没怎么修改。
    \n
    出现的问题的现象是，apache的线程全部用完（802个），weblogic相对比较空闲，内存消耗一般，CPU（4颗的）的idea也在50%左右；前端表现是页面打开速度相当慢，基本不可用。
    \n
    问题的分析过程是，先看到apache的error的log里面很多“文件找不到”错误，由于编辑做的页面上引了一些并不存在的资源，导致的，怀疑此类错误太多，会影响性能，于是找出错误页面，让编辑修复其中巍峨文件引用。但是效果不是很明显，虽然error少了很多。
    \n
    继续分析，使用netstat -an看到很多端口被占用，且很多处于CLOSE_WAIT状态，找个脚本统计下，如下：
    \n
    [wwwpps@IceskYsl]$ netstat -n | awk '/^tcp/ {++S[$NF]} END {for(a in S)  print a, S[a]}'

    \nFIN_WAIT1 3
    \nFIN_WAIT2 52
    \nSYN_SENT 1
    \nTIME_WAIT 725
    \n
    可以看到，确实很多，感觉这里是有问题，google得到一些资料，说到这个问题会导致：“大量的CLOSE_WAIT连接，直接占满TCP队列，导致Apache失去响应。”
    \n
    解决这个问题的方法是修改系统的参数，系统默认超时时间的是7200秒，也就是2小时，这个太大了，对于我们这样的负荷来说，于是修改如下几个参数：
    \n
    sysctl -w net.ipv4.tcp_keepalive_time=30
    \nsysctl -w net.ipv4.tcp_keepalive_probes=2
    \nsysctl -w net.ipv4.tcp_keepalive_intvl=2
    \n
    然后，执行sysctl命令使修改生效，基本上就算完成了。目前正在观察中，看看下午高峰时候效果如何，就可以基本上得出结论了。

    今天看看如何在Rails中实现类似的功能,思路是一样的,可以缓存在数组或者Hash里面,这里为了查找方便,我们选择使用Hash.
    \n
    也就是:如何创建一个变量从rails开始运行时初始化，一直维持到rails终止，而且对于每一个request都能共享的变量？
    \n
    1,首先在environment.rb里面(如果您使用的Rails2以上版本,建议放在initializers目录里面,自己创建一个文件即可)定义一个ruby中的全局变量即可，例如$actions_in_mem在ruby里面，以$开头的变量即自动申明为全局变量）。在rails启动的时候，执行在environment.rb和initializers里面的文件，初始化$actions_in_mem,这样$actions_in_mem即可持续使用了,如:
    \n
    \n
    Ruby代码
    \n
      \n    
    1. $actions_in_mem = Hash.new  
      \n    
      2. \n
    \n
    \n
     
    \n
    2,然后在controller或者model或者view里面都是可用的了,比如在model里面实现刷新:
    \n
     
    \n
    \n
    Ruby代码
    \n
      \n    
    1. #刷新缓存  
      2. \n    
    2. def Action.refresh  
      3. \n    
    3.   Action.get_actions(1).each do |ac|  
      4. \n    
    4.     put_into_hash(ac.controller+"_"+ac.action,ac.id)  
      5. \n    
    5.   end  
      6. \n    
    6. end  
      7. \n    
    7.   
      8. \n    
    8. def Action.put_into_hash(key,value)  
      9. \n    
    9.   $actions_in_mem.store(key, value)  
      10. \n    
    10.   logger.info("@@actions_in_mem.size=\#{$actions_in_mem.size}---\#{key}=>\#{value}")  
      11. \n    
    11. end  
      \n    
      12. \n
    \n
    \n
    3,当然,你可以在controller中定义一个方法手工刷新这个全局变量,或者定时刷新即可,如下代码实现手工刷新.
    \n
     
    \n
     
    \n
    \n
    Ruby代码
    \n
      \n    
    1. #刷新缓存数据  
      2. \n    
    2. def refresh_actions  
      3. \n    
    3.   Action.refresh  
      4. \n    
    4. end  
      \n    
      5. \n
    \n
    \n
     
    \n
    4,最后是在view里面显示或者维护,如下代码段:
    \n
    \n
    XML/HTML代码
    \n
      \n    
    1. <ul>  
      2. \n    
    2.   <% $actions_in_mem.each do |key,value|%>  
      3. \n    
    3.     <li><%=key%>=><%=value%></li>  
      4. \n    
    4.   <%end%>  
      5. \n

    wowo,真是个好东西,EC2一直以来都被人诟病之一的就是其IP地址的动态的,也就是当你重启您"镜像"后,你的IP地址会变化,也就是说,你的域名需要才信修改IP指向,或者采用一个老外写的一个插件(忘记脚啥名字了)来动态解析,比较不爽的很.现在EC2终于推出了"静态IP"功能,我粗略的看了下,其和账户是绑定的,也就是你重启自己的"镜像"后,并不失效.

    Elastic IP addresses are static IP addresses designed for dynamic cloud computing.    An Elastic IP address is associated with your account, not a particular instance,    and you control that address until you choose to explicitly release it. Unlike    traditional static IP addresses, however, Elastic IP addresses allow you to    mask instance or availability zone failures by programmatically remapping your    public IP addresses to any instance associated with your account. Rather than    waiting on a data technician to reconfigure or replace your host, or waiting    for DNS to propagate to all of your customers, Amazon EC2 enables you to engineer    around problems with your instance or software by programmatically remapping    your Elastic IP address to a replacement instance.

    \n
    1、界面不算简洁，比QQ有余，比Gtalk不足
    \n
    都说Hi的界面清爽，偶看了下，比起QQ或者MSN确实干净了不少，QQ的花里胡哨最让我受不了，用了一段时间TM后，还是觉得不爽，最后就不用QQ了；MSN的界面上的广告太嚣张，偶尔还会弹出来，哎，也不喜欢。Gtalk的节目最简洁，简洁到我一使用就喜欢上了。Hi的界面，有点MSN的风格，但是暂时没发现广告，不晓得还能干净多久。
    \n
    2、功能实用，但有不足
    \n
    IM作为最实用的工具（中国是这样的），有些功能是必须的，即时消息，文件传输这两个我觉得是必须的；语音和视频可有可无，如果能支持SMS就更好了，呵呵。Hi基本上具备了这些功能（SMS的没有）。但是我在使用过程发现，文件传输比较不正常，开始想试试传输速度，无奈的900K的东西，半天没反应，又自动断了，还提示双方“对方取消”，引起不少误解；后来试了一个小的图片，还是不行。看来这里有BUG..
    \n
    3、自身功能还有待加强
    \n
    我修改设定了自己的图片，无奈的是报告错误而无法完成，这应该也有Bug。
    \n
    其他的没兴趣试了，此次的Baidu的Hi体验，非常一般。

    \n都说Hi的界面清爽，偶看了下，比起QQ或者MSN确实干净了不少，QQ的花里胡哨最让我受不了，用了一段时间TM后，还是觉得不爽，最后就不用QQ了；MSN的界面上的广告太嚣张，偶尔还会弹出来，哎，也不喜欢。Gtalk的节目最简洁，简洁到我一使用就喜欢上了。Hi的界面，有点MSN的风格，但是暂时没发现广告，不晓得还能干净多久。
    \n2、功能实用，但有不足
    \nIM作为最实用的工具（中国是这样的），有些功能是必须的，即时消息，文件传输这两个我觉得是必须的；语音和视频可有可无，如果能支持SMS就更好了，呵呵。Hi基本上具备了这些功能（SMS的没有）。但是我在使用过程发现，文件传输比较不正常，开始想试试传输速度，无奈的900K的东西，半天没反应，又自动断了，还提示双方“对方取消”，引起不少误解；后来试了一个小的图片，还是不行。看来这里有BUG..
    \n3、自身功能还有待加强
    \n我修改设定了自己的图片，无奈的是报告错误而无法完成，这应该也有Bug。
    \n其他的没兴趣试了，此次的Baidu的Hi体验，非常一般。

    1、stop/start模式就是先stop掉，再启动，他会等到线程结束后stop，启动时会再次读取配置文件。

    经历了Java/Rails的乱码洗礼，经过Zip/RAR/7zip等等的搔扰，经过不懈的恶补，偶以为面对乱码问题可以应对自如了，然而不幸的是，这次又遇到了，下面看过程。
    \n
    问题现象：
    \n
    1、在Rails中，上传本地的文件到服务器，服务器接收到以后，保存到服务器并记录其所在的路径，然后使用Rails中的 send_file来实现下载功能。我在本地开发环境上一切正常，但是在服务器上发生“找不到文件”的错误，SSH连进去看了下，原来保存在硬盘上时，中文文件名出现乱码，类似“2008_03_25_07_54_27_娣樺疂瓒呯骇鐢ㄦ埛鎼滅储寮曟搸.rar”这样的。
    \n
    2、在Rails中使用Ruby的File.new()、File.open()函数创建的文件，在硬盘上显示的中文名也是乱码。（这个人和我发现的问题类似：http://www.javaeye.com/topic/66371）
    \n
    问题分析及其定位：
    \n
    经过查找和分析，偶认为这与系统的字符集设置有关，因为在我本地开发机器上是可以正常显示和查看的，但是在服务器上就不可以，着重了解字符集的设置。
    \n
    分析过程：
    \n
    1、先看看系统
    \n
    1sters@IceskYsl:~$ uname -a
    \nLinux 1sters 2.6.18-xen #1 SMP Fri Nov 2 06:14:54 UTC 2007 x86_64 GNU/Linux
    \n
    恩，是linux的系统。
    \n
    2、再看看目前的字符集
    \n
    1sters@IceskYsl:~$ locale
    \nLANG=
    \nLC_CTYPE="POSIX"
    \nLC_NUMERIC="POSIX"
    \nLC_TIME="POSIX"
    \nLC_COLLATE="POSIX"
    \nLC_MONETARY="POSIX"
    \nLC_MESSAGES="POSIX"
    \nLC_PAPER="POSIX"
    \nLC_NAME="POSIX"
    \nLC_ADDRESS="POSIX"
    \nLC_TELEPHONE="POSIX"
    \nLC_MEASUREMENT="POSIX"
    \nLC_IDENTIFICATION="POSIX"
    \nLC_ALL=
    \n
    这是默认的POSIX。
    \n
    3、查看下系统支持的字符集
    \n
    locale -a
    \n
    修改方法：
    \n
    在/etc/bashrc中加入
    \nexport LC_ALL="zh_CN.utf8"
    \nexport LANG="zh_CN.utf8"
    \n系统默认的locale变成了zh_CN.utf8

    \n经过查找和分析，偶认为这与系统的字符集设置有关，因为在我本地开发机器上是可以正常显示和查看的，但是在服务器上就不可以，着重了解字符集的设置。
    \n分析过程：
    \n1、先看看系统
    \n1sters@IceskYsl:~$ uname -a
    \nLinux 1sters 2.6.18-xen #1 SMP Fri Nov 2 06:14:54 UTC 2007 x86_64 GNU/Linux
    \n恩，是linux的系统。
    \n2、再看看目前的字符集
    \n1sters@IceskYsl:~$ locale
    \nLANG=
    \nLC_CTYPE="POSIX"
    \nLC_NUMERIC="POSIX"
    \nLC_TIME="POSIX"
    \nLC_COLLATE="POSIX"
    \nLC_MONETARY="POSIX"
    \nLC_MESSAGES="POSIX"
    \nLC_PAPER="POSIX"
    \nLC_NAME="POSIX"
    \nLC_ADDRESS="POSIX"
    \nLC_TELEPHONE="POSIX"
    \nLC_MEASUREMENT="POSIX"
    \nLC_IDENTIFICATION="POSIX"
    \nLC_ALL=
    \n这是默认的POSIX。
    \n3、查看下系统支持的字符集
    \nlocale -a
    \n修改方法：
    \n在/etc/bashrc中加入
    \nexport LC_ALL="zh_CN.utf8"
    \nexport LANG="zh_CN.utf8"
    \n系统默认的locale变成了zh_CN.utf8
    \n参考资料：

    时常还是要在另外一台电脑上使用windows，也只能使用putty或者SecureCRT,连接到服务器上，但是一直以来，都存在一些小问题，这里以SecureCRT为例把解决方法汇总下。
    \n
    1、中文显示乱码的问题
    \n
    该问题的现象是用SecureCRT连接到服务器上，比如tail应用日志的时候，其日志中的中文不能很好的显示（也就是乱码）。这个问题的根本原因是双方的编码方式不一致，因为一般的来说，服务器上的编码是UTF-8（我的服务器是这样的，或者被我设定为这样的）你可以在服务器上使用locale 查看，而SecureCRT的默认设置的字符编码是保持系统一致的，在中文windows上就是GBK或者其他编码；
    \n
    知道原因修改起来就比较简单了，分为两个部分：
    \n
    1）修改远程linux机器的配置
    \nvim /etc/sysconfig/i18n
    \n把LANG改成支持UTF-8的字符集
    \n如：
    \nLANG=”zh_CN.UTF-8″
    \n或者是
    \nLANG=”en_US.UTF-8″
    \n
    或者是修改指定用户的locale，编辑.bashrc文件，导入以上的编码即可。
    \n
    2）然后再改Secure CRT的设置
    \nOptions -> Session Options ->  Apperance -> Fonts -> Character（选项->会话选项->外观->字符编码->uft-8）
    \n
    \n退出，再重新登录。发现utf8的文件都能正确读了，utf8的文件名也能正确显示了。
    \n
    2、显示颜色
    \n
    显示颜色是个好习惯，一来直观明了，二来增加美感，对视力也有好处，在Secure CRT中设置显示颜色也比较简单，如下：
    \nOptions -> Session Options ->Terminal ->Emulation ->ANSI Color 选中就可以了。
    \n
    3、字体选择
    \n
    选择不同的字体，可以显示不同的效果，按照个人喜好，比如我自己就喜欢细一点的，清晰一点的字体，而这个字体在Secure CRT是可以设置的，其默认的是vt100，我个人比较喜欢“新宋体”的显示效果。（PS.很多人喜欢fixedsys 字体）。设置方法也很简单，如下：Options -> Session Options ->  Apperance -> Fonts 选择你需要的字体即可。

    今天在月光的blog上看到其对DreamHost的抱怨，说起存在“过度销售”的现象，具体的可以看这里（http://www.williamlong.info/archives/1301.html）。
    \n
    这里说说我自己使用过的和了解到的国外服务器提供商的个人感受，纯属个人感受，请不要乱扣帽子。我选空间的用途主要是有2个，其一是运行一些我开发的开源的系统（比如1stlog，byeloo！等）的Demo，用来演示或者流量不大的应用；其二是为客户选择的跑商业化的RoR应用。所以我选择的服务区必须可以支持RubyOnRails应用。
    \n
    我使用过的国外提供商有BlueHost，DreamHost和SliceHost，我试用过的有亚马逊的EC2，RaislHost,hostingrails和railsplayground；我了解过的有mt和Railsmeches，如下分别说说个人感受：
    \n
    1、BlueHost：这个是我最开始使用的国外的服务器，当时是从朋友那分了一些空间过来使用的，因为最开始的时候，Rails的服务器并不多，貌似只有BH和DH吧，呵呵，BH虽然支持Rails，但是限制相当多，我记得当时我写的“技能云”就放上面，那次被InfoQ报道了下后，那天流量稍微大些，就撑不住了。且速度一般般，映像不咋好，后来就撤离了。
    \n
    2、DreamHost：这个我使用的时间比较长，包括现在这个blog也是放在上面的，总的来说，马马虎虎，只能用来放个人blog和一些Demo等，不适合做商业站点使用；我开始使用的是Share模式的，但是后来开发的一个系统需要在后台跑一些定时JOB，其不支持，就只能开通其PS服务（这个速度相当慢，我等了20多天，来来回回的交互了好多次邮件，他们都说申请开通PS的客户太多，他们忙不过来，需要耐心的等，后来最后我怒了，说再不搞好，我就给我所有的客户选择SliceHost，这招见效，立马搞定，推荐大家使用，哈哈）。
    \n
    其Share模式的用户非常的多，月光说他的那个服务器上有380个shell用户和1600多的FTP，都是很正常的，主要是其销售模式，带来巨量的用户群，而其宣称的500G空间和5T的月流量，无限子域名，无限MYSQL库等等，都是扯淡的，为了吸引眼球和骗那些新入手的朋友，他们对CPU和内存的限制非常严格（这就是他们的高明之处），一旦超过内存和CPU，你必须升级到PS模式。
    \n
    而升级到PS模式（最低是150M内存/150MHZCPU/15美刀/月，以此随自己调解，以10MHZcpu/10M内存/1美刀/月的价格）以后，他会再三提醒您，如果mem不够，请增加自己的内存等。
    \n
    虽然PS号称是”私有服务器“，其效果和许诺的CPU和MEM都可以得到保证，但是也不是很稳定，毕竟用户群那么大，出问题的小概率事件也会很多的。
    \n
    值得称道的是，他们的技术支持还是不错的，我每次发邮件问，基本上很快就给我比较明确的答复；另外，DH的网速还是不错的（就我使用的那个服务器看）；其操作面板比较容易操作，也非常强大。付款比较方便，支持信用卡，paypal以及google checkout等。
    \n
    总的来说：DH的share模式比较适合流量小的和一些demo演示之类的应用，不适合商业化的服务；PS模式稍微好点，但是要做好down机的准备，呵呵。
    \n
    3、SliceHost：这个应该是最便宜的VPN提供商了，其比较专业，以VPN的方式提供服务，可以选择的种类最低是256M独立内存，可以自己选择操作系统类型，自己装web服务器等，其技术文档比较多且可操作性比较好，但是其技术支持不是很到位，我只在chat里和他们沟通过，没发过邮件。
    \n
    SliceHost我上次使用的是256M的ubuntu7.10+nginx+mogrel集群跑的一个Rails应用，用apache的ab压力测了下，效果还不错，且没有出现down机等不稳定现象的出现，比较令人满意。
    \n
    但是有个问题，需要注意，我当时需要在程序里么net/http 取国内一些网站上的资源，速度很让人郁闷，有时候竟然只有900B/秒，相当慢。我曾和他们的技术支持沟通，他们给的解释是“SliceHsot在美国，而您要取得资源在中国，这个网路上的事情，我们也无能为力”，所以，如果您有类似需求，请千万注意。
    \n
    其他几个，类似EC2和Mt等，由于我没有实际长时间使用过，这里就不评价了，最近会逐一试试，以后再补充这个文章。
    \n
    如果您使用过其他的国外的服务器，还请分享一二；或者想更多的了解我使用过的这些服务器，请留言即可。

    \n但是有个问题，需要注意，我当时需要在程序里么net/http 取国内一些网站上的资源，速度很让人郁闷，有时候竟然只有900B/秒，相当慢。我曾和他们的技术支持沟通，他们给的解释是“SliceHsot在美国，而您要取得资源在中国，这个网路上的事情，我们也无能为力”，所以，如果您有类似需求，请千万注意。
    \n其他几个，类似EC2和Mt等，由于我没有实际长时间使用过，这里就不评价了，最近会逐一试试，以后再补充这个文章。
    \n如果您使用过其他的国外的服务器，还请分享一二；或者想更多的了解我使用过的这些服务器，请留言即可。

    由于打算将我的第一个开源项目1stlog重构和完善，看了下以前的实现方式，除了用到了很对rails2不支持的方法和插件外（正在着手修改），还用到了Rails中的component的。而这正是被很多railser们告诫要小心的地方，甚至有人说component是evil的，新版1stlog发布在即，我得好好了解下component为什么evil。
    \n
    一、为什么当时选择component
    \n
    选择component是根据当时的设计需求来的，1stlog设计的时候是作为一个只有基本blog功能的大框架，而其他的一些个性化功能，需要由其他开发人员或者爱好者来按照一定的规范开发和编写，当时认为，使用component时自简单有效的策略，您可以参考我当时编写”1stlog插件开发指南“。
    \n
    二、为什么说component是邪恶的
    \n
    有人说Rails中的component是邪恶的，千万不要使用，原因呢，还真不清楚，看到有人这么写：\n

      7. \n
    \n
    \n
    \n
    也有人拿typo中使用component导致响应很迟钝的数据说明，可以参考“Components may not be evil, but they sure can be slow”，再看看Rails的DHH咋说的呢？哦，他说”Why engines and components are not evil but distracting“
    \n
    这么看来，component并不邪恶了，只是慢一点，有些小问题罢了。
    \n
    三、还用不用？
    \n
    竟然大家都持谨慎态度，那么我们还用不用呢？用！但是或许得换个方式用。此话怎么讲？因为有一个既可以实现component功能，又不evil的东西出现了，那就是Cells，何谓Cells？还是看他的自白好了：
    \n
    \"\"
    \n
    \n
    A rails plugin to push things towards component-oriented architecture. Controller logic and views are encapsulated in lightweight cells and can be rendered like render_component.
    \n
    \n
    哦，看来是个好东西，还想多了解点，看看这些文章吧，"Cells: Bringing Components Back Into Rails 3"或者中文简要版本”插件Cells：把模块化带入Rails 应用中，组件导向轻量级的开发“，还可以看看道喜的简介”Rails框架：组件理念是否重返Rails框架“，或者看看中文的一个简单那的例子”有人用过cell么？“，如果想更深入的了解，可以看看”Ruby Component Web Frameworks“
    \n
    四、还有更好的？
    \n
    我是不知道了，您要是知道的话，还请告诉我。

    开始写这个之前，我不得不佩服下Amazon，不用说别的，就其SimpleDB，S3,EC2这几个就足以让业界大为惊叹，这些都比较熟悉了，今天说的是另外一个类似的东西，Amazon Simple Queue Service（SQS）。
    \n
    看名字，大概就可以猜出大概的意思了，对，就是队列服务，SQS就是一个简单的队列服务，你可以创建一个队列，然后从不同的地方往里面放东西，然后又可以在不同的地方不停的往外取东西，想想看，这不就是分布式协作么。
    \n
    但是需要注意的是，往里面放的时候，消息必须是txet，也就是是说不能放Hash或者数组啥的，如果您有类似需求，请接着往后看，我将提供一个变通的方法。
    \n
    一、简介SQS
    \n
    Amazon Simple Queue Service (Amazon SQS) offers a reliable, highly scalable, hosted queue for storing messages as they travel between computers. By using Amazon SQS, developers can simply move data between distributed components of their applications that perform different tasks, without losing messages or requiring each component to be always available.
    \n
    二、如何使用
    \n
    Ruby的社区足够活跃，每个应用都能找到对应的Gem或者插件，这给了我们足够的方便，针对SQS，我推荐的两个gem，分别是：
    \n
    1、SQS Gem
    \n
    \n
    这个插件是Amazon SQS官方站点写的教程《Using Amazon S3, EC2, SQS, Lucene, and Ruby for Web Spidering》上使用的，足够的简单，但是其主页貌似访问不了了，只能通过Google Cach看看。
    \n
    使用非常方便，流程如下
    \n
    1）安装：gem install SQS
    \n
    2）测试：ruby test/all_tests.rb
    \n
    3）使用示例\n
    \n
    Ruby代码
    \n
      \n    
    1. require 'rubygems'  
      2. \n    
    2. require 'sqs'  
      3. \n    
    3.   
      4. \n    
    4. SQS.access_key_id = 'YOURACCESSKEYID'  
      5. \n    
    5. SQS.secret_access_key = 'YOURSECRETACCESSKEY'  
      6. \n    
    6.   
      7. \n    
    7. q = SQS.create_queue 'myFantasticQ'  
      8. \n    
    8. puts q.url  
      9. \n    
    9.   
      10. \n    
    10. SQS.each_queue do |q|  
      11. \n    
    11.   puts q.name  
      12. \n    
    12. end  
      13. \n    
    13.   
      14. \n    
    14. q = SQS.get_queue 'myFantasticQ'  
      15. \n    
    15.   
      16. \n    
    16. q.send_message 'This is a message!'  
      17. \n    
    17.   
      18. \n    
    18. m = q.receive_message  
      19. \n    
    19. puts m.body  
      20. \n    
    20. m.delete  
      21. \n    
    21.   
      22. \n    
    22. q.each_message do |m|  
      23. \n    
    23.   # note that #each_message is an infinite loop!  
      24. \n    
    24.   # you must either break out of it, or delete each message you receive  
      25. \n    
    25.   m.delete  
      26. \n    
    26. end  
      27. \n    
    27.   
      28. \n

    \n
    \n其他文章，可以自己Google。
    \n
    2、RightScale gems
    \n
    RightScale gems是RightScale 从其产品里面提取出来的，这个现象很常见，就像Shopify 中提取的Active Merchant一样，从一个成熟的产品中提取出来一个gem，其可用性是相当高的。
    \n
    使用方法大同小异，不再赘述，如果感兴趣，请到上面的地址上自行查看。
    \n
    三、如何扩展
    \n
    前面我们说了，SQS中容纳的消息是text的，但是看其文档表述，是这样写的：
    \n
    \n
    New messages can be added to a queue at any time. The message body can contain up to 8 KB of text in any format.
    \n
    \n
    any time？啥意思？奇怪。
    \n
    我认为一种可行的办法是，把Hash转成ymal格式的（.to_yaml），然后放进去后；取出的时候，直接YAML.load(message.body)，然后再还原即可了。
    \n
    看段代码，如下：
    \n
    \n
    \n
    Ruby代码
    \n
      \n    
    1. require 'SQS'  
      2. \n    
    2. class Tsqs  
      3. \n    
    3. SQS.conf_file = 'sqs_conf.yml'  
      4. \n    
    4. s = SQS.new  
      5. \n    
    5. puts s.api_version  
      6. \n    
    6. puts s.conf_file  
      7. \n    
    7. puts s.url_for_query  
      8. \n    
    8. iceskysl = s.get_queue('iceskysl_message')  
      9. \n    
    9. books_to_update = { 'bookid'=>"1",'url'=>"url1",'queue'=>"queue1"}  
      10. \n    
    10. iceskysl.send_message(books_to_update.to_yaml)  
      11. \n    
    11.   
      12. \n    
    12. iceskysl_messages = iceskysl.receive_messages  
      13. \n    
    13. puts iceskysl_messages.size  
      14. \n    
    14. iceskysl_messages.each do |message|  
      15. \n    
    15.  params = YAML.load(message.body)  
      16. \n    
    16.  puts "bookid=" + params[:bookid] + ",url=" + params[:url] +  ",queue=" + params[:queue]  
      17. \n    
    17.   message.delete  
      18. \n    
    18. end

    开始写这个之前，我不得不佩服下Amazon，不用说别的，就其SimpleDB，S3,EC2这几个就足以让业界大为惊叹，这些都比较熟悉了，今天说的是另外一个类似的东西，Amazon Simple Queue Service（SQS）。
    \n看名字，大概就可以猜出大概的意思了，对，就是队列服务，SQS就是一个简单的队列服务，你可以创建一个队列，然后从不同的地方往里面放东西，然后又可以在不同的地方不停的往外取东西，想想看，这不就是分布式协作么。
    \n但是需要注意的是，往里面放的时候，消息必须是txet，也就是是说不能放Hash或者数组啥的，如果您有类似需求，请接着往后看，我将提供一个变通的方法。
    \n一、简介SQS
    \nAmazon Simple Queue Service (Amazon SQS) offers a reliable, highly scalable, hosted queue for storing messages as they travel between computers. By using Amazon SQS, developers can simply move data between distributed components of their applications that perform different tasks, without losing messages or requiring each component to be always available.
    \n二、如何使用
    \nRuby的社区足够活跃，每个应用都能找到对应的Gem或者插件，这给了我们足够的方便，针对SQS，我推荐的两个gem，分别是：
    \n1、SQS Gem
    \n
    \n这个插件是Amazon SQS官方站点写的教程《Using Amazon S3, EC2, SQS, Lucene, and Ruby for Web Spidering》上使用的，足够的简单，但是其主页貌似访问不了了，只能通过Google Cach看看。
    \n使用非常方便，流程如下
    \n1）安装：gem install SQS
    \n2）测试：ruby test/all_tests.rb
    \n3）使用示例
    \n
    \nRuby代码
    \n
    \n    require 'rubygems'  
    \n    require 'sqs'  
    \n      
    \n    SQS.access_key_id = 'YOURACCESSKEYID'  
    \n    SQS.secret_access_key = 'YOURSECRETACCESSKEY'  
    \n      
    \n    q = SQS.create_queue 'myFantasticQ'  
    \n    puts q.url  
    \n      
    \n    SQS.each_queue do |q|  
    \n      puts q.name  
    \n    end  
    \n      
    \n    q = SQS.get_queue 'myFantasticQ'  
    \n      
    \n    q.send_message 'This is a message!'  
    \n      
    \n    m = q.receive_message  
    \n    puts m.body  
    \n    m.delete  
    \n      
    \n    q.each_message do |m|  
    \n      # note that #each_message is an infinite loop!  
    \n      # you must either break out of it, or delete each message you receive  
    \n      m.delete  
    \n    end  
    \n      
    \n    q.approximate_number_of_messages  
    \n    q.visibility_timeout  
    \n    q.visibiltit_timeout = 3  
    \n      
    \n    q.delete  
    \n
    \n
    \n其他文章，可以自己Google。
    \n2、RightScale gems
    \nRightScale gems是RightScale 从其产品里面提取出来的，这个现象很常见，就像Shopify 中提取的Active Merchant一样，从一个成熟的产品中提取出来一个gem，其可用性是相当高的。
    \n使用方法大同小异，不再赘述，如果感兴趣，请到上面的地址上自行查看。
    \n三、如何扩展
    \n前面我们说了，SQS中容纳的消息是text的，但是看其文档表述，是这样写的：
    \n
    \nNew messages can be added to a queue at any time. The message body can contain up to 8 KB of text in any format.
    \n
    \nany time？啥意思？奇怪。
    \n我认为一种可行的办法是，把Hash转成ymal格式的（.to_yaml），然后放进去后；取出的时候，直接YAML.load(message.body)，然后再还原即可了。
    \n看段代码，如下：
    \n
    \n
    \nRuby代码
    \n
    \n    require 'SQS'  
    \n    class Tsqs  
    \n    SQS.conf_file = 'sqs_conf.yml'  
    \n    s = SQS.new  
    \n    puts s.api_version  
    \n    puts s.conf_file  
    \n    puts s.url_for_query  
    \n    iceskysl = s.get_queue('iceskysl_message')  
    \n    books_to_update = { 'bookid'=>"1",'url'=>"url1",'queue'=>"queue1"}  
    \n    iceskysl.send_message(books_to_update.to_yaml)  
    \n      
    \n    iceskysl_messages = iceskysl.receive_messages  
    \n    puts iceskysl_messages.size  
    \n    iceskysl_messages.each do |message|  
    \n     params = YAML.load(message.body)  
    \n     puts "bookid=" + params[:bookid] + ",url=" + params[:url] +  ",queue=" + params[:queue]  
    \n      message.delete  
    \n    end  
    \n    end  
    \n
    \n
    \n看明白了么，没问题吧，呵呵。另外，这里还有一篇文章使用的是RightScale gems。

    \n
    Dear Amazon Web Services developers,\n
    We've often told you that one of our goals is to drive down costs continuously and to pass those savings on to you. We have been able to reduce our costs for data transfer, so we're pleased to announce that we're lowering our pricing for data transfer, effective May 1, 2008. You'll notice below that we've reduced price at every existing usage tier of transfer out, as well as added an additional tier for the heaviest users.
    \n
    Current data transfer price (through April 30, 2008)
    \n$0.100 per GB - data transfer in
    \n$0.180 per GB - first 10 TB / month data transfer out
    \n$0.160 per GB - next 40 TB / month data transfer out
    \n$0.130 per GB - data transfer out / month over 50 TB
    \n
    Data transfer "in" and "out" refers to transfer into and out of the Amazon service. Data transferred between Amazon EC2 and Amazon S3-US, Amazon SimpleDB and Amazon SQS is free of charge (i.e., $0.00 per GB). Data transferred between Amazon EC2 and Amazon S3-Europe will be charged at regular rates.
    \n
    New data transfer price (effective May 1, 2008)
    \n$0.100 per GB - data transfer in
    \n$0.170 per GB - first 10 TB / month data transfer out
    \n$0.130 per GB - next 40 TB / month data transfer out
    \n$0.110 per GB - next 100 TB / month data transfer out
    \n$0.100 per GB - data transfer out / month over 150 TB
    \n
    Data transfer "in" and "out" refers to transfer into and out of the Amazon service. Data transferred between Amazon EC2 and Amazon S3-US, Amazon SimpleDB and Amazon SQS is free of charge (i.e., $0.00 per GB). Data transferred between Amazon EC2 and Amazon S3-Europe will be charged at regular rates.
    \n
    The result of this pricing change is that all customers will see a reduction in the price of transfer out. For example, a customer transferring 50TB a month will save 16% and a customer transferring 500TB a month will save 26% on transfer with the new pricing. Please see http://aws.amazon.com for full pricing information for each service.
    \n

    \nThe Amazon Web Services Team

    在上次（2008.01.10）简单了写了一篇《RubyOnRails + S3 + EC2 = ? 》至今已经有段时间了，经过一段时间的发展，Amazon Web Services到今天已经相当成熟了，一整套的解决方案可以给Web App带来很多的便利，再一系列的改进措施后，AWS基本上是成熟了。
    \n
    \"\"
    \n
    上面这个图片来源于slideshare上的一个PPT“Using Amazon SimpleDB with Ruby on Rails”，正如我上面截取的这个图片说的：
    \n
      \n    
    • 静态文件存储在S3上；
      • \n    
    • App server使用课余无限扩展的EC2；
      • \n    
    • 结构化数据存储在SimpleDB上；
      • \n    
    • 客户端/服务端的交互使用SQS；
      • \n
    \n
    看看AWS的几个应用，正好覆盖了WebApp的整个过程，以下逐一介绍下这几个服务：
    \n
    1、S3看上去就是一个大的硬盘，你可以把App中的所有数据都放上去，取回来，展示等等，是个比较安全的存储服务，省略了自己买磁盘阵列，维护等等费用，且号称是安全的。
    \n
    2、EC2的最大卖点就是其可以无限伸缩的，号称可以扩展到“云”上去，不用因为您的服务器压力过重而购买一批一批的机器，免得找机房，等等，可谓相当方便，在其推出固定IP和固态存储之后，使得EC2相当成熟；
    \n
    3、SimpleDB推出的最早，但是一直没仔细看，以为其和S3差不多，今天仔细看了下，其实不然，看其名字是SimpleDB，是用来替代DB的，但是比普通的DB更加Simple，其实也就是一个结构化的存储，你可以把DB的东西（表，行）组合一下放进去，然后根据其有的API查询和存贮，省了维护数据库的人力物力，但是速度不晓得如何。
    \n
    4、SQS是前段时间了解的，不晓得这个服务当初推出的典型应用场景是什么样的，就我的理解，其就是一个队列，相当于一个缓冲队列，用在分布式处理或者作用同步上相当不错，有兴趣的可以看我以前的文章“Amazon SQS,分布式作业不再费心”。
    \n
    总的来说，AWS的几个服务都是将WebApp开发中涉及到的几个方面分拆出来做成服务，以来提供便捷，二来自己赚了一大笔，真是聪明，不过这些应用的维护不晓得Amazon 是怎么处理的，肯定不会是我们常见的人工维护，估计和Google存储差不多的自维护系统。
    \n
    如果您对AWS感兴趣，如果您和笔者一样使用的是RubyOnRails，你可以使用RightAws插件，其包含了以上4个应用的实现，相当不错。
    \n

    在上次（2008.01.10）简单了写了一篇《RubyOnRails + S3 + EC2 = ? 》至今已经有段时间了，经过一段时间的发展，Amazon Web Services到今天已经相当成熟了，一整套的解决方案可以给Web App带来很多的便利，再一系列的改进措施后，AWS基本上是成熟了。
    \n
    \n上面这个图片来源于slideshare上的一个PPT“Using Amazon SimpleDB with Ruby on Rails”，正如我上面截取的这个图片说的：
    \n
    \n    静态文件存储在S3上；
    \n    App server使用课余无限扩展的EC2；
    \n    结构化数据存储在SimpleDB上；
    \n    客户端/服务端的交互使用SQS；
    \n
    \n看看AWS的几个应用，正好覆盖了WebApp的整个过程，以下逐一介绍下这几个服务：
    \n1、S3看上去就是一个大的硬盘，你可以把App中的所有数据都放上去，取回来，展示等等，是个比较安全的存储服务，省略了自己买磁盘阵列，维护等等费用，且号称是安全的。
    \n2、EC2的最大卖点就是其可以无限伸缩的，号称可以扩展到“云”上去，不用因为您的服务器压力过重而购买一批一批的机器，免得找机房，等等，可谓相当方便，在其推出固定IP和固态存储之后，使得EC2相当成熟；
    \n3、SimpleDB推出的最早，但是一直没仔细看，以为其和S3差不多，今天仔细看了下，其实不然，看其名字是SimpleDB，是用来替代DB的，但是比普通的DB更加Simple，其实也就是一个结构化的存储，你可以把DB的东西（表，行）组合一下放进去，然后根据其有的API查询和存贮，省了维护数据库的人力物力，但是速度不晓得如何。
    \n4、SQS是前段时间了解的，不晓得这个服务当初推出的典型应用场景是什么样的，就我的理解，其就是一个队列，相当于一个缓冲队列，用在分布式处理或者作用同步上相当不错，有兴趣的可以看我以前的文章“Amazon SQS,分布式作业不再费心”。
    \n总的来说，AWS的几个服务都是将WebApp开发中涉及到的几个方面分拆出来做成服务，以来提供便捷，二来自己赚了一大笔，真是聪明，不过这些应用的维护不晓得Amazon 是怎么处理的，肯定不会是我们常见的人工维护，估计和Google存储差不多的自维护系统。
    \n如果您对AWS感兴趣，如果您和笔者一样使用的是RubyOnRails，你可以使用RightAws插件，其包含了以上4个应用的实现，相当不错。
    \n但是其不足之处依然存在，例如多国内用户，速度不敢恭维；也有人列举了“Top 10 Reasons to Avoid the SimpleDB Hype”,当然也有人针锋相对的回应了这10个问题“ Top 10 Reasons to Avoid Document Databases FUD  4 ”；另外还有其价格是否真的划算（现在支付美刀比较划算），以及其曾经出现过的问题，所以您在决定使用之前还请仔细考量，这几个应用我都有过尝试，虽然没有大规模的使用，但是基本上比较了解了，如果您有问题，或者其他的经验，欢迎和我交流。

    1、Gmail与Google在线办公结合
    \n
    可以通过设置Gmail的过滤器为“有附件”且包含“DOC or XML”关键字的邮件转发到您的GoogleDoc的“Email-In Your Documents and Files"中，详细说明可以参考”Gmail过滤器妙用 之与Google在线办公结合“。

    2、Gmail Labels和过滤器结合在备份中的妙用
    \n
    Gmail的lable功能很强大，和上面说的过滤器结合可以做很好的备份用，例如我订阅了很多的邮件列表，想nginx，mogrel等等，这些邮件列表相当活跃，如果每次都如inbox，会严重干扰我其他的邮件，这时lable和过滤器就可以结合来做归档了，详细的操作方法请参考”Gmail Labels在备份中的妙用“

    \n绮梦 10:20:47  
    \n啊 总理摔到了， 
    \n绮梦 10:21:35 
    \n照片我正在传给北京，不经过审核的是不允许发布的 
    \n绮梦 10:22:21  
    \n我和几个同行现在开了9台电脑，同时在传消息 
    \n绮梦 10:22:37

    \n老爷子的手臂受伤出血了，他把要给他包扎的医务人员推开了 
    \n绮梦 10:27:09 
    \n好消息，发现一名学生了  
    \n绮梦 10:28:00 
    \n总理跑到塌方点了，在帮忙呢 
    \n绮梦 10:28:13 
    \n向峨乡中学 
    \n绮梦  10:28:33 
    \n拖出来了，医生在抢救 
    \n绮梦 10:28:56 
    \n部队上来的人还不是很多 
    \n绮梦 10:29:07  
    \n交通太困难 
    \n绮梦 10:29:42 
    \n现在还不一定，这个看样子看活着，吊瓶氧气都挂上了 
    \n绮梦 10:31:06  
    \n啊，又塌了 
    \n绮梦 10:31:28 
    \n突击队一个人被埋进去了 
    \n绮梦 10:31:40  
    \n等等，我到前面看看 
    \n绮梦 10:36:24 
    \n我回来了，抢救出来了 
    \n绮梦 10:37:16  
    \n最新消息，彭州被困的10万群众危险！！！ 
    \n绮梦 10:38:49  
    \n由于大雨的影响，工程兵几次架桥失败，附近已经出现泥石流迹象，电话直接是叫通总理的，情况很危险！！！ 
    \n绮梦 10:39:19  
    \n由于桥梁倒塌，彭州市10万群众被堵在山中，救灾人员和物资无法运人。已经出现泥石流迹象 
    \n绮梦 10:41:11  
    \n总理电话里大喊，我不管你们怎么样，我只要这10万群众月兑险，这是命令。他把电话摔了 
    \n绮梦 10:41:33  
    \n头一次看见老爷子这么厉害 
    \n绮梦 10:41:54 
    \n汶川现在还没通知去，估计情况不是很好 
    \n绮梦 10:42:16  
    \n我现在在通讯帐篷里 
    \n绮梦 10:43:54 
    \n汶川最新消息，雨开始小了，空投物资已经扔下去了，空降兵已经在外围机场登机了  
    \n绮梦 10:45:19 
    \n现在所有的国外记者都在关注号称中国最精锐的特种部队首次公开亮相

    \n绮梦 11:12:51  
    \n我现在在直升机上，估计一个小时后就到什肪了 
    \n绮梦 11:34:40  
    \n最新消息，汶川的映秀、漩口、卧龙三镇通讯信号很弱，至今也无法联系。估计三镇有将近两万多人被困，余震不断，大雨连绵，情况非常严峻，由于能见度太差，无法判断准确情况。总参命令，当空降部队到达汶川上空时，如果条件不允许，就不惜代价强行伞降！  
    \n绮梦 11:36:38 
    \n没有，飞机要进人雷区了，我要关机了，等会再和你们聊。

    \n
    CSRF这种攻击方式虽然提出来很久（在2006年的时候就有了）了，但是这个沉睡的攻击巨人直到前不久才逐渐走入我们的视线，到底CSRF是啥，危害到底有多大？常见的利用方式是如何的，今天作为“安全相关 | Security”分类的第一篇文章，我按照自己的理解告诉你，不要低估了CSRF危害性和攻击能力。
    \n
    \n一、什么是CSRF
    \n先看看CSRF的原文说明，如下：
    \n
    \n
    Cross Site Reference Forgery works by including malicious code or a link in a page that accesses a web application that the user is believed to have authenticated. If the session for that web application has not timed out, an attacker may execute unauthorized commands.
    \n
    二、CSRF案例说明和分析
    \n自然，这里拿Rails程序来举例子说明这些问题，大家知道Rails2之前是把session放在服务器端（文件或者DB或者缓存中），客户但在 cookie中保存sessionid；而到了Rails2后，还有一种方式是把session放在基于cookie的客户端中。当然这两样都各有道理， 各有优劣，不在我们这次说的范围之内。我们继续说，当我们向一个域名发送一个请求的时候，如果本店存在这个域名的cookie，浏览器会自动的把 cookie附带上。这样本来没有啥问题，也是我们为了解决http无状态记录的解决方案，但是有个问题出现了，如果出现一个到其他域名的请求，浏览区在 加载的时候，也把cookie给带上了，会有什么问题？我们举个简单的也很常见的例子来说明这个问题。
    \n-----------------------------案例------------------------------
    \n1、Bob在自己的电脑上刚刚查看完自己的银行A账户余额，然后比较无聊就跑到一个公开的BBS上灌水，当他看到一篇“银行A的内部照片”的帖子，很有兴趣的打开这个帖子想看看自己信任的银行A的内部图片是啥样子的，殊不知，这其实是一个attacker精心设计的骗局。
    \n2、在这个帖子中确实有几个图片，看上去真的像是银行A的照片，但是其中有个图片没显示出来，Bob以为是自己网速太慢，导致这个图片没有加载进来，也没在意。只是对这些并不是十分满意的照片摇摇头，就关了这个帖子。
    \n3、几天后，Bob猛然发现自己在银行A的账户上少了1000元，到底是怎么了？
    \n
    \n分析：
    \n为什么钱少了呢？我们得分析一下上面这个案例，好记得当时Bob说有个图片没显示么，是的，我们来看看这个图片的地址,惊奇的发现是：<img .src="http://www.banka.com/transfer?account=myself&amount=1000&destination=attacker">，这是一个什么地址？聪明的您一定很快就能明白，这个地址是邪恶的，看上去，他的意思是打开这个地址的人，给attacker转了1000元。
    \n这怎么可能？你肯定急了，我怎么能随便给一个人转1000元呢，而且我都不知道呀！但是，注意了，这其实是完全有可能的。还记得当时Bob刚刚查看完整及的帐号信息，基于银行A的cookie并不过期，当出现如上链接出现在src的时候（    note that .src is meant to be src），浏览器尝试着按照本地的cookie去加载上面这个URL，而银行A验证了来源请求的cookie是可以的，所以就这样事情就悄悄的发生了。
    \n    -------------------------------案例结束---------------------------
    \n
    \n    ok，看明白了么，这就是CSRF，一句话给他下个定义就是：借你的cookie在你不知道的时候悄悄的做了一些你不愿意做 的事情。恶日期这里有个更要命的是，这个包含上述URL的图片或者链接，并不需要一定是放在银行A的服务器上，相反可以在任一地方，比如blog，公开的 BBS，或者一些群发的Mail中等等，如此多的场合下，这些都有可能存在陷阱。
    \n再看一副图片吧，其说明的正是CSRF的攻击原理。
    \n\"\"
    \n
    \n 三、CSRF的预防
    \n看上去很恐怖吧，是的，确实恐怖，意识到恐怖是个好事情，这样会促使你接着往下看如何改进和防止类似的漏洞出现。
    \n总体来说，预防CSRF主要从2个方面入手，分别是：
    \n1、正确使用GET,POST和Cookie；
    \n2、在non-GET请求中使用Security token；
    \n
    \n    一般上，大家知道的浏览器发送请求的方式有GET或者POST，但是还有一种比较常用的是Cookie，至于其他的HTTP协议请求方式，你可以google，一般按照W3C的规范：
    \n1、GET常用在查看，列举，展示的时候；
    \n2、POST常用在下达订单，改变一个资源的属性或者做其他一些事情    ；
    \n
    \nok，我们这里拿Rails按照前面列举的2种预防手段做说明，首先，我们可以在Rails的控制权中（controller）将一些方法（action）限定（verify）为只能使用POST或者GET，例如：\n
    \n
    Ruby代码
    \n
      \n    
    1. verify :method => :post, :only => [ :transfer ], :redirect_to => { :action => :list }   
      2. \n
    \n
    \n恩，很好，这样做下限制以后，前面案例中的方法就失效了，因为这里我们限定了transfer必须使用POST来提交请求，当GET请求来的时候并不会被响应。
    \n万事大吉了？NO！因为POST的请求也是可以被构造出来后自动发送的，如何实现，看下面吧，你肯定会吃惊的。
    \n
    \n
    XML/HTML代码
    \n
      \n    
    1. <a .href="http://www.1sters.com/" onclick="var f = document.createElement('form'); f.style.display = 'none'; this.parentNode.appendChild(f); f.method = 'POST'; f.action = 'http://www.example.com/account/destroy'; f.submit();return false;">点我试试</a>  
      2. \n
    \n
    \n是的，这就是一个活生生的例子(.href is meant to be href)，使用link的href或者img的src都可以的，再想想一个Attacher放了一个图片，然后写了一个    onmouseover方法，执行上述的那段JS，如下，或者使用AJAX。\n
    \n
    XML/HTML代码
    \n
      \n    
    1. <img .src="http://www.harmless.com/img" width="400" height="400" onmouseover="…" />  
      \n    
      2. \n
    \n
    \n所以，限定为POST后还不是非常的保险，怎么办？不急，我们还有第二步，给non-GET的请求设置 security token，如何实现，在Rails2以后非常简单（也是默认的），我们只需要在environment.rb中添加如下代码：
    \n
    \n
    Ruby代码
    \n
      \n    
    1. config.action_controller.session = {  
      2. \n    
    2.   :session_key => '_csrf_session',  
      3. \n    
    3.   :secret      => 'ae4b43dda38ff78bb50898b2935da76d1e224061ab72a9399d34cea4c6178eee6dae815fff920a20642f27abda83b793da4e9b6cf20c4838805e80abf53e318a'  
      4. \n    
    4. }  
      5. \n
    \n
    \n然后    在application controller中包含如下security token设置：
    \n
    \n
    Ruby代码
    \n
      \n    
    1. protect_from_forgery  :secret => '053cef294a333f72c3584311799c69d2'  
      2. \n
    \n
    \nok，基本上安全了，如果这时POST请求过去，但是    security token和session计算出来的secret和服务端的secret匹配不上的话，就会返回一个ActionController::InvalidAuthenticityToken错误，防止该类缺陷的出现。
    \n安全了，也许你要说，那我如果能破解出    protect_from_forgery，不进OK了么，按照理论上是，但是实际是破解是基本上不可能的，因为有人曾计算过，暴力破解该串大概需要2的11次方时间，后续我将再写一篇文章详细的介绍，这里不再赘述。
    \n
    \n    四、总结
    \n总的来说，CSRF的兴起刚刚开始，网络上肯定会有一股热潮，Railser们一定要注意自己的程序的安全性，CSRF比你我能想到的更有威胁，千万别小瞧了它。

    CSRF这种攻击方式虽然提出来很久（在2006年的时候就有了）了，但是这个沉睡的攻击巨人直到前不久才逐渐走入我们的视线，到底CSRF是啥，危害到底有多大？常见的利用方式是如何的，今天作为“安全相关 | Security”分类的第一篇文章，我按照自己的理解告诉你，不要低估了CSRF危害性和攻击能力。
    \n
    \n一、什么是CSRF
    \n先看看CSRF的原文说明，如下：
    \n
    \nCross Site Reference Forgery works by including malicious code or a link in a page that accesses a web application that the user is believed to have authenticated. If the session for that web application has not timed out, an attacker may execute unauthorized commands.
    \n二、CSRF案例说明和分析
    \n自然，这里拿Rails程序来举例子说明这些问题，大家知道Rails2之前是把session放在服务器端（文件或者DB或者缓存中），客户但在 cookie中保存sessionid；而到了Rails2后，还有一种方式是把session放在基于cookie的客户端中。当然这两样都各有道理， 各有优劣，不在我们这次说的范围之内。我们继续说，当我们向一个域名发送一个请求的时候，如果本店存在这个域名的cookie，浏览器会自动的把 cookie附带上。这样本来没有啥问题，也是我们为了解决http无状态记录的解决方案，但是有个问题出现了，如果出现一个到其他域名的请求，浏览区在 加载的时候，也把cookie给带上了，会有什么问题？我们举个简单的也很常见的例子来说明这个问题。
    \n-----------------------------案例------------------------------

    前面已经说了“与时俱进,使用Git”，用了几天git后，越来越觉得不错，如下说说SVN和Git的主要区别：
    \n
    \n
    Git是分布式SCM，而SVN是基于服务器的，也就是说每个开发者本地都有一套git库，每个人维护自己的版本（或者合并其他人的版本），而SVN是每个人写完代码后都及时的checkin到服务器上，进行合并。
    \n
    \n
    如果上面这段话还不能让你真正了解Git的好处，而不想使用git来替代你的svn的话，那么我再列举几个我认为不错的比较直观的场景：
    \n
    1、可以在本地（离线）就做好版本控制，而不用时刻连网，特别是Soho一族或者喜欢经常到处跑，又喜欢在路上、车上或者马路旁边的小凳子上coding的人；这个时候你可以在自己的Git库上进行版本控制，而不用到处找网络把代码搞到svn上去。
    \n
    2、分布式的SCM更加安全和健壮，有没有想过，如果你的SVN版本服务器挂掉了（硬盘坏了或者网络不可用等等），你会咋样，能修复的好么，一旦修复不好，资料都完蛋了，而Git的分布式SCM，其中的几个节点挂掉影响并不大。
    \n
    3、速度，你如果使用GoogleCode或者其他的SVN服务的话，不知道你是否有呆呆的等待chenkin完成的情况（我是经常有的），而Git，毫无疑问，速度快的多，（就算是使用GitHub也快），究其原因，应该是Git是打包好了上传，而不像SVN单个文件上传。
    \n
    4、版本、分支管理
    \n
    还有啥？想不来了，差不多就这样了，视个人情况而定，但是我认为Git会让你更加满意。
    \n
    但是有人可能会有这样的想法，我本地使用git，然后定时的checkin到SVN上，这样岂不是更好，啊哈，好吧，你还不习惯或者还有其他的特殊情况（比如其他开发者不喜欢git，或者原来的代码在svn上等等），这里看看如何把git和svn结合起来一起使用。
    \n
    1、比较笨的方法
    \n
    同时使用Git和SVN，然后再各自的“忽略”列表里面加加上对方的版本库，比如在svn的忽略列表中加上.git，而同时在git的.gitignore中加上.svn；然后执行各自的命令。
    \n
    2、比较靠谱的方法
    \n
    使用git-svn应该算更加科学和靠谱的方法，安装好git-svn（这个是需要单独安装的）后，就可以使用啦，基本上是这样的：
    \n
    mkdir 1stlog
    \ncd 1stlog && git-svn init http://1stlog.googlecode.com/svn/trunk/
    \n
    其他的就不多说了，可以参考“git and subversion”和“Howto use Git and svn together”以及“git-svn 常用功能示例”。

    很早前就说过，我非常喜欢使用GoogleDoc来写技术文章，其好处有很多：
    \n
    \"\"
    \n
    1、编辑、组织、协作、维护方便
    \n
    GoogleDoc的编辑器我非常喜欢，去掉Word中那些我基本上用不上的功能，而只提供需要的功能，这是比较难得可贵的，“不要让用户思考”是一种好的用户体验，而我深信，google在这个方面比盖茨大叔做的更符合我的需求。
    \n
    我可以按照不同的文件夹或者Tag来组织我的文章，可以快速方便的索引和搜索到需要找到的文档。
    \n
    GoogleDoc的协助功能也非常的榜，我经常和其他人一起完成一份文档的编写，这比在本地写一份文档传来传去要方便，合理的多。我们经常一起编写，在意见不一致的地方批注，等待其他人的确认等等。
    \n
    另外，每次修改都有历史版本信息，可以很轻松的找到以前的版本，这点相当的好呀。
    \n
    2、在线存储，更加方便
    \n
    GoogleDoc是在线存储的，按照google和amazon的“云计算”的概念，这应该算云计算的一种了，其强大的云存储能力，我相信比存在我本地或者我自己的服务器上更加安全和可靠，且我可以随时随地的联网更新和查看，而不需要随身拿个U盘带来带去，还要提防丢失U盘的噩梦。
    \n
    另外，这样比直接发布在自己的Blog要可靠的多，谁知道您的blog服务商或者自己的blog服务器会不会那天罢工，或者哪天你的域名失效，或者那天您的数据库崩溃了，还有。。。
    \n
    3、离线功能，锦上添花
    \n
    以前有人说“要是我上不了网，那我岂不是死翘翘了！”，呵呵，现在有了离线功能，可以在本地编辑，然后在有网络的时候再传上去就OK了。
    \n
    4、不一安装，且自动更新，不断完善
    \n
    GoogleDoc还有个好处是，其不用每次修复一个漏洞或者增加一个新功能都要down下来重新安装，他在服务端更新了，我就可以即刻体验，免去一切不必要的麻烦。另外，他的功能还在不断的增加，比如我就很期待一个可以自动给代码着色的功能，那样我写文章里面的代码就可以更加直观了。只是我不知道谁还有和我类似的需求，也没有找到反馈的地方，有人有类似需求的么？帮我一起反馈上去吧 :)
    \n
    相信随着网速的越来越快，所谓的云计算都能得到很好的应用。我现在只有工作的时候写相关文档才被迫使用Word，虽然在家的本本上的Ubuntu下有Openoffice，但是写自己的一些技术文章的时候，我还都是使用GoogleDoc。且可以利用其它的技术（比如GoogleSite）来整合、组织和展示文档。大家可以在IceskYsl@Docs上看到我分享出来的一些技术文档。

    当MYSQL成为越来越多的web2站点的选择的DB的时候，当站点越来越大，流量越来越多，用户越来越多的时候，数据库往往第一个成为系统的瓶颈，如何提升DB的性能成为系统成败的关键点，本文只是从自己的认识上说说可以从几个方面提升MYSQL的性能，以及可以采取的扩展方式。但是不会详细的阐述，详细的说明和操作，分析方法以后有时间再仔细分享。
    \n
    一、选择合适的数据库存贮引擎
    \n
    MYSQL支持的引擎很多，例如MyISAM，MEMORY，InnoDB等等类型，每个类型试用的场景是不一样的，恰当的选择存储引擎可以节省你不少时间，详细的介绍你可以参考”第15章：存储引擎和表类型“。
    \n
    二、优化SQL语句
    \n
    不要以为SQL语句关系不大，按照以往的经验，往往几个畸形的SQL就可以拖垮一个DB，决定不是危言耸听，在从系统优化和DB优化及其扩展之前，请仔细检查系统中用到的SQL，先解决SQL可能带来的问题，而经验是，做好这步，就可以解决很多初期的性能问题。
    \n
    三、建立索引
    \n
    这和前面的SQL优化有一定的联系，仔细查看你的SQL语言，尽可能的优化他，然后建立必须的索引，千万不要忽视了索引的威力，我们曾经有过测试，2W条的基本数据，生成页面，没有索引前，推算其全部生成需要的时间是81个小时，而加上索引后，只需要12分钟，多大的性能提升，各位可以自己那计算器粗略的算算。
    \n
    四、建立分区&表空间
    \n
    很多人以为只有Oracle才有表空间，分区这些东西，不想到MYSQL中也有类似的东西吧，尽管这个东西是mysql5才引入的，尽管其还不是很成熟，但是毫无疑问，这是一个好的信号，在我们使用MYSQL的时候就有了更多的方案来提升性能了。
    \n
    分区一般分为水平分区和垂直分区，MYSQL目前只支持水平分区，有RANGE,LIST,HASH,KEY等等分区方式，详细说明以后再说，你可以参考”第18章：分区“，"通过分区（Partition）提升MySQL性能"等文章。
    \n
    表空间的相关话题，可以参考”第17章：MySQL簇“，不在赘述。
    \n
    五、调整MYSQL和系统参数
    \n
    这个方案是伴随着整个性能提升过程的，你的不时的调整参数以得到更好的性能，这个比较复杂，没有啥成文的规定，都是靠经验或者实践得到的。
    \n
    六、集群或者proxy
    \n
    到这里为止，单机的MYSQL基本上可以优化调整的都涉及到了，如果这个时候还是顶不住压力，该考虑水平扩展或者垂直扩展了，垂直扩展比较容易，只要针对单机的性能得到瓶颈的所在，增加CPU或者内存或者换比较强劲的设备就可以很快得到立竿见影的效果。
    \n
    但是垂直扩展能力有限，不可能得到无限级的扩展，风险也比较大，除了垂直扩展，大家选择较多的是水平扩展，也就是通过增加服务器，无限的得到性能的扩展，当然这个里面内容是很多的，如何做到数据库的备份，同步等都是需要考虑和解决的问题，而且还要考虑这么多机器间的数据重复成都等问题；除此之外，还有可能将数据库缓存到memcached或者使用mysql proxy等实现连接池之类的方案，都是需要考虑和抉择的。
    \n
    以上每个分类都是个大的话题，这么一篇文章只是说明了优化的思路和基本流程，其中涉及到很多东西，例如诊断和分析等都是很有技术含量的，我们下次会一个专题一个专题的仔细分析，力求将MYSQL的性能达到尽可能的榜。

    WillPaginate这个插件很棒，以至于其取代了Rails中原有的Paginate方法，虽然看上其很简单，其实还是有不少技巧的，本篇用来记录我遇到的或者使用到的一些tips。
    \n
    \n1.直接使用paginate
    \n这个比较简单，也是使用的最多的，如下：
    \n
    \n
    Ruby代码
    \n
      \n    
    1. def self.get_all_items_in_catelog( catelog_id,page,per_page="10")  
      2. \n    
    2.   paginate :per_page => per_page, :page => page,  
      3. \n    
    3.     :conditions =>["catelog_id = ? and caiji > 0",catelog_id],  
      4. \n    
    4.     :order => 'created_at DESC ,updated_at  DESC'  
      5. \n    
    5. end  
      \n    
      6. \n
    \n
    \n
     2.使用Model.paginate_by_sql
    \n有的时候，你需要的SQL用Rails拼的时候有些不方便，这个时候可以考虑使用paginate_by_sql来实现，这个没啥好说的，你需要什么样的SQL直接写就可以了，例如：
    \n  #排行榜列表
    \n
    \n
    Ruby代码
    \n
      \n    
    1. def self.get_all_items_in_rank(rank_id, page,per_page="10")  
      2. \n    
    2.     Book.paginate_by_sql ["SELECT DISTINCT `books`.* FROM `books` LEFT OUTER JOIN `ranksorts` 
      \n    
      3. \n    
    3. ON (`books`.`prodid` = `ranksorts`.`prodid`) LEFT OUTER JOIN `ranks`  
      \n    
      4. \n    
    4. ON (`ranks`.`id` = `ranksorts`.`rank_id`) WHERE (ranks.id = ?) 
      \n    
      5. \n    
    5. ORDER BY books.updated_at DESC,books.created_at DESC", rank_id],  
      6. \n    
    6.       :page => page, :per_page => per_page  
      7. \n    
    7. end  
      8. \n

    \n1.SliceHost（生产系统性价比最高）
    \nSliceHost是一家很棒的VPS服务商提供诸如Ubuntu（提供好几个版本）、CentOS、Debian 4.0、Fedora 9、Gentoo好几种系统发行版选择，可以选择256M、512M、1G等好几种方案，拥有root权限，完全自主，非常稳定且价格在VPS中是最便宜 的，适合做生产环境，极力推荐。
    \n如果你感兴趣，按照如下两个方式得到最大优惠：
    \n1.点击优惠的SliceHost过去注册；
    \n2.注册时“Referral email address”输入"iceskysl@gmail.com"即可。
    \n另外，值得一提的是，其可以重新rebuild发行版（会丢失数据，切记备份），使用Slicehost的感觉就是自己除了物理接触外，完全拥有。且其相关的教材、文章非常详细，我在其上部署的Nginx+Mongrel+Vlad+MySQL非常棒。

    \n
    2.DreamHost（Demo演示类性价比最高）
    \n
    DreamHost在Rails和PHP的支持上还是不错的，部署和定制都很方便，其支持无限域名绑定，500G硬盘和无限流量，虽然有赚取眼球的嫌疑，但是用来给客户做Demo演示、个人Blog等等非常适合，你可以按照如下两个中的任意方式得到其允许的最大优惠额度：

    \n再次感受到社区的力量，很多朋友一般是不怎么联系的，但是这事情一发动就得到大家的积极响应，人多力量果然很大。
    \n相信，这本书很快就可以和大家见面了,:)
    \n这是个不错的模式，希望以后还能有机会找到好资料，大家协作完成。

    Q. How do I install Ubuntu ftp service or server?
    \n
    A. Ubuntu Linux comes with various ftp servers to setup FTP service such as:
    \n=> proftpd - Versatile, virtual-hosting FTP daemon
    \n
    => vsftpd - The Very Secure FTP Daemon
    \n
    => ftpd - FTP server
    \n
    => wu-ftpd - powerful and widely used FTP server
    \n
    => wzdftpd - A portable, modular, small and efficient ftp server
    \n
    => pure-ftpd - Pure-FTPd FTP server
    \n
    其中vsftpd相当优秀，其配置简单方便，且非常安全，如下是其主页上的说明：
    \n
    vsftpd is the Very Secure File Transfer Protocol Daemon. The server can be launched via a super-server such as inetd or xinetd. Alternatively, vsftpd can be launched in standalone mode, in which case vsftpd itself will listen on the network.
    \n
    => Default ftp port : 21
    \n=> Default configuration file : /etc/vsftpd.conf
    \n
    Q：如何安装vsftpd
    \n
    很简单，即可搞，如下：
    \n
    \n### Step # 1: Install vsftpd\n
    Type apt-get command to install vsftpd
    \n````$ sudo apt-get install vsftpd```
    \nOutput:
    \n

    Adding new user `ftp' (106) with group `nogroup'.
    Not creating home directory `/home/ftp'.
     * Starting FTP server: vsftpd```\n
    \n### Step # 2: Configure /etc/vsftpd.conf\n
    The default vsftpd configuration file is /etc/vsftpd.conf. You need to edit this file using text editor such as vi:
    \n````$ sudo vi /etc/vsftpd.conf```
    \n
    Add the following line (uncomment line) to the vsftpd configuration file:
    \n````local_enable=YES```
    \nAbove config directive will allow local users to log in via ftp
    \n
    If you would like to allow users to upload file, add the following to the file:
    \n````write_enable=YES```
    \n
    For security you may restrict local users to their home directories. Add the following to the file:
    \n````chroot_local_user=YES```
    \n
    Save and close the file.
    \n### Step # 3: Restart vsftpd\n
    To restart vsftpd type the command :
    \n````$ sudo /etc/init.d/vsftpd restart```
    \nOutput:
    \n``* Stopping FTP server: vsftpd                                                                                       [ ok ]
     * Starting FTP server: vsftpd                                                                                       [ ok ]

    add following rules to your iptables script. Assuming that default
    incoming policy is drop. If protocol is TCP and destination port is 21
    (ftp):

    ````iptables -A INPUT -p tcp -m tcp --dport 21 -j ACCEPT```

    See - How do I open open ftp port 21 using iptables for more information.```\n
    There are a large number of other configuration options available for vsftpd that can be used to fine tune ftp server. Read vsftpd.conf man page by typing following command:
    \n````$ man vsftpd.conf```

    \n\n
    总的来看，有两个方式来实现对WML的支持，单独支持和整合支持，下面详细的说。
    \n\n
    一、按照一般方式支持
    \n\n
    这个方式和做PC WEB方式是一样的，有个单独的controller或者action，指定特有的layout和页面模板，而这些模板中采用WML语言编写，在请求到来的时候，按照URL中特有的特征字符（比如二级域名）或者Http Head中的标识转向Wap的action，进而显示。详细的步骤基本上是这样的：
    \n\n
    1、在app/controllers/application.rb中增加对WAP格式输出的支持
    \n
    \nRuby代码
    \n
    \n    before_filter :set_wap_content_type, :only => :wap  
    \n      
    \n    def set_wap_content_type  
    \n      @headers["Content-Type"] = “text/vnd.wap.wml; charset=iso-8859-1″  
    \n    end  
    \n
    \n
    \n2、添加一个WAP的全局布局模板app/views/layouts/wap.rhtm
    \n
    \nXML/HTML代码
    \n
    \n    <?xml version=”1.0″?>  
    \n    <!DOCTYPE wml PUBLIC “-//WAPFORUM//DTD WML 1.1//EN” “http://www.wapforum.org/DTD/wml_1.1.xml”>  
    \n    <wml>  
    \n    <card title=”<%= @title %>”>  
    \n    <p align=”center”>  
    \n    <%= @content_for_layout %>  
    \n    </p>  
    \n    </card>  
    \n    </wml>  
    \n
    \n
    \n3、在我的controller中（index）中增加一个action用来响应WAP请求。
    \n
    \nRuby代码
    \n
    \n    def wap  
    \n      @title = "San Francisco Sailing Weather"  
    \n      render(:layout => "wml")  
    \n    end  
    \n
    \n
    \n4、添加相应的view模板app/views/index/wap.rhtml
    \n
    \nXML/HTML代码
    \n
    \n    <%= link_to 'NOAA Marine Forecast', { :controller => '/marine/forecast', :action => 'wap' } %><br/>  
    \n    <%= link_to 'Wind Readings', { :controller => '/marine/wind', :action => 'wap' } %><br/>  
    \n    <%= link_to 'Current Predictions', { :controller => '/marine/tide', :action => 'wap' } %>  
    \n
    \n
    \n 
    \n\n
    二、使用Rails2支持的多模板类型支持
    \n\n
    在Rails2以后，Rails支持多种格式的输出，比如Html，RSS，JS等，当然你还可以定制自己的格式，比如我们这里说的WML，Iphone等，使用起来更简单、自然。
    \n\n
    1、添加MIME格式支持
    \n\n
    在config/environment.rb中增加MIME的格式支持，方式如下：
    \n
    \nRuby代码
    \n
    \n    Mime::Type.register "text/vnd.wap.wml", :wml  
    \n
    \n
    \n
    \n2、判断请求类型
    \n<div class="codeText">
    \n<div class="codeHead">Ruby代码</div>
    \n<ol class="dp-rb" start="1">
    \n    <li class="alt"><span><span class="comment"># application.rb</span><span>  </span></span></li>
    \n    <li><span>before_filter <span class="symbol">:adjust_format_for_beta</span><span>  </span></span></li>
    \n    <li class="alt"><span>  </span></li>
    \n    <li><span>...  </span></li>
    \n    <li class="alt"><span>  </span></li>
    \n    <li><span><span class="keyword">def</span><span> adjust_format_for_beta  </span></span></li>
    \n    <li class="alt"><span>  request.format = <span class="symbol">:beta</span><span> </span><span class="keyword">if</span><span> beta_request?   </span></span></li>
    \n    <li><span><span class="keyword">end</span><span>  </span></span></li>
    \n    <li class="alt"><span>  </span></li>
    \n    <li><span><span class="keyword">def</span><span> beta_request?  </span></span></li>
    \n    <li class="alt"><span>  <span class="keyword">return</span><span> (request.subdomains.first == </span><span class="string">"beta"</span><span> || params[</span><span class="symbol">:format</span><span>] == </span><span class="string">"beta"</span><span>)  </span></span></li>
    \n    <li><span><span class="keyword">end</span><span>  </span></span></li>
    \n</ol>
    \n</div>
    \n<pre style="font-size: 90%;">
    \n<strong>3、添加相应的view代码</strong>比较简单，就是写XML或者WML模板<strong>show.wml.erb</strong>
    \n
    \nXML/HTML代码
    \n
    \n    xml.instruct! :xml, :version => "1.0"  
    \n    xml.wml "xml:lang" => "en-gb" do  
    \n      xml.card :title => "My title here" do  
    \n        xml.p "Something interesting here"  
    \n        xml.p "Something else interesting here."  
    \n      end  
    \n    end  
    \n
    \n
    \n
    \n4、添加输出类型支持
    \n<div class="codeText">
    \n<div class="codeHead">Ruby代码</div>
    \n<ol class="dp-rb" start="1">
    \n    <li class="alt"><span><span class="keyword">def</span><span> index  </span></span></li>
    \n    <li><span>  respond_to <span class="keyword">do</span><span> |format|  </span></span></li>
    \n    <li class="alt"><span>    format.html  </span></li>
    \n    <li><span>    format.wml  </span></li>
    \n    <li class="alt"><span>  <span class="keyword">end</span><span>  </span></span></li>
    \n    <li><span><span class="keyword">end</span><span>  </span></span></li>
    \n</ol>
    \n</div>
    \n<pre style="font-size: 90%;">
    \n以上两中方式，我个人更加喜欢Rails2的多模板支持模式，更加自然和清晰。<strong>实用工具：</strong><a href="http://addons.mozilla.org/firefox/addon/62">wmlbrowser add-on for Firefox</a> ：可以在FF下直接查看WML网页<a href="http://cn.opera.com/">Opera</a>：支持WML格式显示

    说明打开响应页面的类型，如果403的类型过多，那可能要注意是否系统遇到了瓶颈。
    \n特殊说明：这里，我们一般会关注到的指标是fetches/sec、msecs/connect
    \n他们分别对应的常用性能指标参数
    \nQpt-每秒响应用户数和response time，每连接响应用户时间。
    \n测试的结果主要也是看这两个值。当然仅有这两个指标并不能完成对性能的分析，我们还需要对服务器的cpu、men进行分析，才能得出结论

    大家都知道，在Rails中比较常见的做法是使用“auto increment”的id做为主键，虽然很便捷，但是也存在以下问题：

    dnsbl_check是个很有意思的插件，它其实就是一个前置过滤器，在请求第一次到来的时候，会根据DNS Blackhole Lists来判断来源IP是否合法，如果合法，放行，并在其session中标识已经被checked，而后再来源就不会再去校验（省了不少资源）；如果来源IP在DBL内，就会显示“Access denied”页面，同时阻止其进一步访问。
    \n\n
    安装和使用：
    \n
    \n    在Rails项目的根目录下执行"script/plugin install http://www.spacebabies.nl/svn/dnsbl_check" ；
    \n    在需要早检查的controllers 中添加"before_filter :dnsbl_check" ；
    \n    重启应用程序.
    \n
    \n在 vendor/plugins 目录下需要包含如下结构文件：
    \n\n
    <site name>/vendor/plugins/dnsbl_check/
    \n|-- 403.html
    \n|-- README
    \n|-- init.rb
    \n|-- install.rb
    \n-- lib
    \n    -- dnsbl_check.rb
    \n\n
    代码示例：
    \n```````
    \n
    \nRuby代码
    \n
    \n    class CommentsController < ApplicationController  
    \n      before_filter :dnsbl_check

    \nJay Pignata已经用Ruby写了一个类库BOSSMan,使用非常方便，步骤如下：
    \n1、安装gem
    \n
    \nRuby代码
    \n
    \n    gem sources -a http://gems.github.com  
    \n    gem install jpignata-bossman
    \n
    \n
    \n
    \n2、编写代码
    \n
    \nRuby代码
    \n
    \n    require 'rubygems'  
    \n    require 'bossman'  
    \n    include BOSSMan  
    \n      
    \n    BOSSMan.application_id = "Your Application ID here"  
    \n      
    \n    news = BOSSMan::Search.news("IceskYsl", 0, 3)  
    \n    news.results.each do |result|  
    \n      puts "\#{result.title} [from \#{result.source}]"  
    \n    end

    \r\nJul 30 19:11:58 www PAM-securetty[1611]: Couldn't open /etc/securetty
    \r\n 经过查找发现其原因是内核中开启的审核子系统LauS (Linux Auditing System)写的日志太多，把/var空间占了，再次登陆的时候，由于无法写日志导致挂在那里，出现假死现象。
    \r\n
    \r\n解决方法：
    \r\n定位到问题以后，就可以想办法解决了，目前可行的办法由四种，分别如下：
    \r\n1、定期手工删除/var/log/audit.d下的日志文件\r\n
    #删除7天前的
    \r\nfind ./ -mtime +7 -type f -exec rm {} \\;
    \r\n2、配置crob自动删除或者备份\r\n
    SEVEN_DAYS_OLD=`/usr/locale/ebin/date '+%d' --date '7 days ago'`
    \r\nif [ -f /var/log/audit/bin/bin.${SEVEN_DAYS_OLD} ]
    \r\nthen
    \r\nrm /var/log/audit/bin.${SEVEN_DAYS_OLD}
    \r\nfi
    \r\n
    \r\n3、修改/etc/audit/audit.conf配置文件
    \r\n可以通过修改audit.conf来配置，让其自动处理
    \r\n1）修改为自动删除的：
    \r\n    notify = \"/usr/sbin/audbin -S /var/log/audit.d/save.%u -C -T 20% -N 'rm -f %f'\";
    \r\n[The notify line as above should (according to the docs) remove old 'save' files when the filesystem comes within 20% of full (change the figure after -T to specify how close to full you want to start deleting old files).]
    \r\n
    \r\n    2）修改为自动备份的：（/backup 是另外您想保存数据的分区）\r\n
    notify = \"/usr/sbin/audbin -S /var/log/audit.d/save.%u -C -T 20% -N 'mv %f /backup'\"; 
    \r\n
    \r\n4、    禁用audtid服务
    \r\n如 果您不需要审核信息，禁用audtid服务 (\"chkconfig --del auditd\"),系统性能会有所提高. 如果想要彻底禁用内核中的audit，可以删除 /dev/audit文件，重新启动。以后可以通过在grub.conf 里kernel行最后加入audit=1来启用。

    SimpleConfig looks nice, but it definitely has a few differences from Configatron. The first big difference is that SimpleConfig is limited to use with Rails. Configatron can be used with any framework, any application, and any script. Configatron also seems a bit easier to use. There are no mixins needed to use it. The configatron method lives in Kernel, which means it’s available everywhere, no ‘configuration’ needed. \":)\" Different strokes, eh? There are a few other configuration systems out there, I always encourage people to check out the options before they decide on a piece of software to use.
    \r\n其实我们自己也可以写，只是没有必要再搞一套，功能上来说，上述这两个足够了，下面简单的看看Configatron 的用法：\r\n1、安装\r\n$ sudo gem install configatron\r\n2、定义（支持namespace）\r\n

    搞Java的人应该很习惯把一些配置（数据库连接、个性化配置等）写到配置文件中，一般会使用XML或者TXT文件中，在启动的时候读取配置，初始化等等。
    \nRails中也可以实现类似的功能，虽然Rails提倡“零配置”，但有的时候开发一个系统，比如Blog系统等还是需要一些个性化的配置，我们原来的实现方式是：增加一个配置文件，启动的时候读取，并保存为全局变量，用的时候直接使用。也很方便。
    \n其实还可以使用插件或者gem来做，Configatron就是这么一个gem，另外还有一个插件版的SimpleConfig，两者还是有些不同的，按照Configatron 作者的说法，其不同点在于：
    \nSimpleConfig looks nice, but it definitely has a few differences from Configatron. The first big difference is that SimpleConfig is limited to use with Rails. Configatron can be used with any framework, any application, and any script. Configatron also seems a bit easier to use. There are no mixins needed to use it. The configatron method lives in Kernel, which means it’s available everywhere, no ‘configuration’ needed.  Different strokes, eh? There are a few other configuration systems out there, I always encourage people to check out the options before they decide on a piece of software to use.
    \n其实我们自己也可以写，只是没有必要再搞一套，功能上来说，上述这两个足够了，下面简单的看看Configatron 的用法：
    \n1、安装
    \n$ sudo gem install configatron
    \n2、定义（支持namespace）
    \n
    \nRuby代码
    \n
    \n    configatron do |config|  
    \n      config.website_url = "http://www.1sters.com"  
    \n      config.namespace(:mems) do |mem|  
    \n        email.namespace(:iceskysl) do |iceskysl|  
    \n          iceskysl.email = "iceskysl@1sters.com"  
    \n          pop.blog_url = "http://iceskysl.1sters.com"  
    \n          # etc ...  
    \n        end  
    \n        email.namespace(:shine) do |shine|  
    \n          smtp.email = "shine@1sters.com"  
    \n          smtp.blog_url = "http://shine.1sters.com"  
    \n          # etc ...  
    \n        end  
    \n      end  
    \n      # etc...  
    \n    end  
    \n
    \n
    \n3、使用
    \n
    \nRuby代码
    \n
    \n    configatron.mems.iceskysl.email # => "iceskysl@1sters.com"  
    \n    configatron.mems.shine.blog_url # => "http://shine.1sters.com"  
    \n    configatron.website_url # => "http://www.1sters.com"  
    \n
    \n
    \n4、重写
    \n
    \nRuby代码
    \n
    \n    configatron do |config|  
    \n      config.website_url = "http://www.1sters.com/index"  
    \n    end

    说句实在话，我不是很喜欢iphone，虽然也试了下，但是我还是不是很喜欢，因为我生活中用到的Mac的东西太少了，与之相比，我认为在iphone和blackberry之间选择的话，我会选择BB，虽然我的第一款BB8100寿命不长，但是我非常喜欢，近期已经在联系入手一款升级版的BB8110。
    \n相比BB和iphone，我更加期待GooglePhone的上市，虽然Iphone在大陆上市一波三折，可能Gphone会吸取教训，更迅速的打开国内市场。
    \n为什么更加期待Google Phone，应该归于与生活中使用到Google的东西太多了，GoogleReader，GoogleDoc，Gmail，Google日历等等，都是必不可少的东西，若干Google手机上可以很好的把这些东西都整合进来，又能保证不会太笨重的话，我会买一部。
    \n期待赶快来吧，详细介绍请移步“iPhone也得低头 万众期待超炫Google手机现身”.

    \n    导入xsstcx.js(未压缩版xsstc.js)
    \n    添加一个id=”Xsstc”的空DIV。
    \n    在JS中调用Xsstc.exec(functionURL, callback)，使用的内容作为callback的参数传入callback中
    \n
    \n其中CSS的定义也有要求，下面是Hello World中CSS的定义
    \n
    \nCSS代码
    \n
    \n&lt;pre lang="css"&gt; ```
    \nXsstc {
    \n background-image: url('about:blank#Hello%20World');
    \n}```
    \n    </pre>``````
    \n
    \n
    \n
    \nJavaScript代码
    \n
    \n    Xsstc.exec('http://lbs.tralfamadore.com/test.css', showResponse)

    \n1、猫的DSL灯不亮，说明信号没进来，看来猫坏了，联系电信的来换了个猫，DSL灯亮了，可以通过本本连接有线上网，猫的问题解除；
    \n2、接下来按照以前的方式走路由器，发现路由器的WAN还是不亮，然后本本有线到路由器上，无法上网，怀疑路由器挂了，幸好买了不久，拿回去换了一个，路由器问题解决；
    \n3、换了路由器后，本本有线连接可以使用，上网正常，但是突然发现两台台式机均无法连接到路由器，还是现实“网线被拔出”的红叉叉，电脑的网卡灯也不亮。
    \n\n
    深入分析：
    \n1、调换本本和台式机的网线，还是老样子，看来不是网线的问题；
    \n2、重装了台式机的网卡驱动，还是老样子，看来不是驱动的问题；
    \n3、两台台式机症状类似，看来是和打雷有关，google了一下，果然，很多人遇到过这样的问题（我还真是第一次遇到），貌似说打雷的时候出现电涌现象，导致网卡损坏。甚至有的会导致主板、显示器都坏掉。
    \n\n
    解决问题：
    \n1、先可以试试是否是主版屏蔽了网卡，在BIOS里面重新加载下板载网卡，是否可以；
    \n2、如果不行，就只能换网卡了，如果用PCI的，得在BIOS里面把板载网卡禁用掉；如果使用USB的，则可以直接使用。
    \n\n
    注意事项：
    \n1、打雷、闪电的时候关闭计算机，拔掉电源，拔掉ADSL线，关掉猫、路由器的电源；
    \n2、晚上睡前，拔掉ADSL，关闭计算机电源。

    经常遇到一些新功能开发完了，需要测试一些指标，比如性能测试等等，这个时候如果人工填充数据会非常囧的，你可以写rake来自己构造填充数据，你需要处理随机产生等情况，现在不必费心了，使用Faker Gem和populator可以快速的构造需要的数据。

    自从用了一段时间blackberry以后，再也用不习惯其他的传统手机，但是又被第一个夭折的黑莓搞得后怕，一直没有入手新的，本来打算前几天去买BB8110的，无奈懒得跑路，又耽搁了。看中G1的网络功能，因为我的手机多半是用来上网，看文档，处理mail等等，加上习惯了Google的很多在线服务，我认为G1会把Google的很多服务集成进去的，所以就一直等待。
    \n\n\n
    有报道说美国运营商T-Mobile将会在今天（9月17日）面向消费者预售这款Google手机，然后会在9月23日在美国纽约正式发布上市。
    \n\n
    值得担心的有两点：不要像iphone一样，被阻挡在门外；不要太贵。
    \n\n
    2、新版的MacBook
    \n\n
    我只是半个mac迷，我买MB是为了更快捷的工作，虽然用了Ubuntu一年多，也还觉得挺满意，但是追求更加高效的工作环境是我梦寐以求的，新版的MB应该会更加轻薄和环保，价格应该不会贵的离谱，可能会比以前的MB更便宜。
    \n\n\n
    有报道称新一代 MacBook 采用超薄铝制外壳、LED 背光显示屏，并且价格是极具冲击力的“入门级价格”。且在10.14号发布，看看表，时间也没多少了。

    对于Rails开发者来说，总觉得一大堆的CSS代码非常碍眼，写起来也不是很优雅，有没有更优雅的方法，毫无疑问，是有的。
    \n\n
    先看一段正常的CSS代码：
    \n
    \nCSS代码
    \n
    \n    div.article div.title {  
    \n      font-weight: bold;  
    \n    }  
    \n    div.article div.title a.author {  
    \n      padding-left: 12px;  
    \n      background: url('user.png') no-repeat left;  
    \n    }  
    \n    div.article div.text {  
    \n      border: 1px solid #EEE;  
    \n      background: #FEF;  
    \n    }  
    \n
    \n
    \n再看一段有那么点不一样的代码：
    \n
    \nCSS代码
    \n
    \n    div.article {  
    \n      div.title {  
    \n        font-weight: bold;  
    \n          
    \n        a.author {  
    \n          padding-left: 12px;  
    \n          background: url('user.png') no-repeat left;  
    \n        }  
    \n      }  
    \n      div.text {  
    \n        border: 1px solid #EEE;  
    \n        background: #FEF;  
    \n      }  
    \n    }  
    \n
    \n
    \n有啥不一样了么？是否有点发懵呢，呵呵，下面这个写法更清晰和优雅，不是么！但是这样写的话，我们的浏览器是不认识的，怎么办，可以采用第三方的类库来转换即可。现在看到的可以做这个事情的有FrontCompiler和css_dryer，除了这个功能外，还有其他的功能，例如FrontCompiler还可以合并多个JS/CSS文件，代码如下：

    \n\n
     
    \n\n\n\n
    歌词如下：
    \n\n
    「稻 香」
    \n作词：周杰伦 作曲：周杰伦
    \n\n
    对这个世界如果你有太多的抱怨
    \n跌倒了就不敢继续往前走
    \n为什么人要这么的脆弱 堕落
    \n请你打开电视看看
    \n多少人为生命在努力勇敢的走下去
    \n我们是不是该知足
    \n珍惜一切 就算没有拥有
    \n\n
    还记得你说家是唯一的城堡 随着稻香河流继续奔跑
    \n微微笑 小时候的梦我知道
    \n不要哭让萤火虫带着你逃跑 乡间的歌谣永远的依靠
    \n回家吧 回到最初的美好
    \n\n
    不要这么容易就想放弃 就像我说的
    \n追不到的梦想 换个梦不就得了
    \n为自己的人生鲜艳上色 先把爱涂上喜欢的颜色
    \n笑一个吧 功成名就不是目的
    \n让自己快乐快乐这才叫做意义
    \n童年的纸飞机 现在终于飞回我手里
    \n\n
    所谓的那快乐 赤脚在田里追蜻蜓追到累了
    \n偷摘水果被蜜蜂给叮到怕了 谁在偷笑呢
    \n我靠着稻草人吹着风唱着歌睡着了
    \n哦 哦 午后吉它在虫鸣中更清脆
    \n哦 哦 阳光洒在路上就不怕心碎
    \n珍惜一切 就算没有拥有
    \n\n
    还记得你说家是唯一的城堡 随着稻香河流继续奔跑
    \n微微笑 小时候的梦我知道

    2.   
      3. \r\n\t
    3. -h or --help  
      4. \r\n\t
    4.     Print quick or full usage details respectively.  
      5. \r\n\t
    5. -r or --recursive  
      6. \r\n\t

      7. \r\n\t
    7. -d or --delete  
      8. \r\n\t
    8.     delete input files after successful conversion. May not be safe yet!!!  
      9. \r\n\t
    9. -v or --verbose

      13. \r\n\t
    13. -p or --pretend  
      14. \r\n\t
    14.     don't convert anything. sneetchalizer will go through the motions and print out the commands it would run. Useful for preview- ing a complex command line to ensure it does what you intend. You should interpret this option's output with a grain of salt. For example, if you include the '--sanitize' option, the files will not really be renamed when using --pretend, and as such the command's output will not reflect that the filenames would be changed during an actual run.  
      15. \r\n\t
    15. -t or --terminate  
      16. \r\n\t
    16.     terminate sneetchalizer options. This is useful if you have to convert '--coolDir' or '-groovySong.mp3'. This is the only option whose order on the command line is significant.  
      17. \r\n\t
    17. -D ARG or --out-directory=ARG  
      18. \r\n\t
    18.     write all outfiles to a directory argument. This is useful if you want to (re)encode files directly to a mounted portable device.  
      19. \r\n\t
    19. --strict and --pedantic  
      20. \r\n\t
    20.     many errors that sneetchalizer may encounter are recoverable, such as specifying a directory as argument that contains no files to convert, or conversion failures in general. By default the script will print an error message and move on to the next file. If you use '--strict' then sneetchalizer will bail out at the first sign of trouble except for tag errors. With '--pedantic' the script will stop even on tag errors.   
      21. \r\n\t
    21. --stasis  
      22. \r\n\t
    22.     Preserve timestamp (mtime) of original file.  
      23. \r\n\t
    23. --threads [N]  
      24. \r\n\t
    24.     Experimental. Use threads to create concurrent jobs. This option takes an optional integer argument which represents the number of threads to launch. The default is two. Preliminary tests suggest there is little advantage (and even diminishing returns) when setting this number greater than the number of cores/CPUs you have. Due to the asychronous nature of threads the --verbose and --show-output flags will be silently disabled and most screen output is supressed.   
      25. \r\n\t
    25. --sanitize  
      26. \r\n\t
    26.     Removes ,, ;, :, ', \", %, @, #, and ` from filenames and tags.  
      27. \r\n\t
    27. -n [FORMAT] or --rename[=FORMAT]  
      28. \r\n\t
    28.     rename all outfiles (and temporary wavs) according to FORMAT. FORMAT is a string with special designators to be pulled from the file tags. The following options are available:

    47. quality and bitrate are passed directly to lame or oggenc depending on mp3 or ogg output format respectively. Both tools can handle either a bitrate or quality argument, so it is important to understand what values are valid for the underlying tool in your specific use case. faac will accept a bitrate argument, but not a quality argument. These options will be silently ignored for any output formats other than mp3, ogg or m4a. Make sure you know what you are doing if you decide to use both in one run, and read each tools manpage for valid values. If these options are omitted the tools builtin defaults are used (-q3 for oggenc and -q5 for lame).

    \r\n
    使用示例：
    \r\n
      \r\n\t
    1. $ sneetchalizer song.mp3  
      2. \r\n\t
    2.   
      3. \r\n\t
    3. The most simple possible example, creates 'song.wav'.  
      4. \r\n\t
    4.   
      5. \r\n\t
    5. $ sneetchalizer --out=ogg --in=flac -q5 /some/music/dir  
      6. \r\n\t
    6.   
      7. \r\n\t
    7. This example converts every flac file in '/some/music/dir' to ogg format at quality 5.  
      8. \r\n\t
    8.   
      9. \r\n\t
    9. $ sneetchalizer -d --out=mp3 --in=ogg,m4a,wma -b 160 .  
      10. \r\n\t
    10.   
      11. \r\n\t
    11. Converts every ogg, m4a, and wma file in the current directory to a 160 kbps constant bitrate mp3 file. The original files are deleted.  
      12. \r\n\t
    12.   
      13. \r\n\t
    13. $ sneetchalizer --out=mp3 --out-optionhook=\"--preset extreme\" /some/wavs  
      14. \r\n\t
    14.   
      15. \r\n\t
    15. Here we encode every wav in '/some/wavs' to mp3 format passing '--preset extreme' directly to lame.  
      16. \r\n\t
    16.   
      17. \r\n\t
    17. $ sneetchalizer --in=ogg --out=ogg --quality=1 norvegianWood.ogg /some/more/oggs  
      18. \r\n\t
    18.   
      19. \r\n\t
    19. Using the same --in and --out format allows us to resample/encode the file at a different bitrate or quality. Note that this will overwrite the original file so only do this on a copy, or use '-D' to write files to another directory.  
      20. \r\n\t
    20.   
      21. \r\n\t
    21. $ sneetchalizer --in=ogg --out=m4a -D /mnt/ipod/ /some/oggs  
      22. \r\n\t
    22.   
      23. \r\n\t
    23. Here we re-encode some ogg files to m4a format and write them to our mounted iPod.   
      24. \r\n

    \r\n4、注意事项\r\n\r\n本脚本只是粘合剂，其他的tool还是需要另外安装的。\r\n\r\n其他信息请参考其主页说明,如果您有这个方面的问题或经验，欢迎和我讨论。\r\n\r\n\r\n\r\n\r\n ", "created_at"=>2008-10-09 02:49:27 UTC, "updated_at"=>2012-06-24 15:53:14 UTC, "body_html"=>"
    前几天写了“采用Ruby提取MP3的metadata信息”后，就在寻找成熟的Ruby代码做差不多的事情，今天找到一个sneetchalizer，仔细的看了下，非常强大。
    \n\n\n
    sneetchalizer其实只是个粘合剂，因为在*unix下，audio格式转换的lib已经非常丰富和成熟，例如lame,gogo,bladeenc,mplayer等等就非常好用；另外，关于audio的tag信息和metadata信息的提取也有比较成熟的lib了，类似id3lib-ruby library,wmainfo-rb library,ruby-ogginfo library等等。而sneetchalizer只是把这些tools粘合起来。
    \n\n
    其支持的格式有:'aac' 'aif' 'aifc' 'aiff' 'aiffc' 'ape' 'au' 'caf' 'cdda' 'cdr' 'copy' 'fap' 'flac' 'gsm''ircam' 'm4a' 'm4b' 'mat' 'mat4' 'mat5' 'mp2' 'mp3' 'mp4' 'mpc' 'mpp' 'nist' 'ofr''ofs' 'ogg' 'paf' 'pvf' 'raw' 'sd2' 'sds' 'sf' 'snd' 'spx' 'svx' 'tta' 'voc''vox' 'w64' 'wav' 'wma' 'wv' 'xi'

    \n\n
    直接下载其gz包，sneetchalizer-0.9.0是现在的最新版本。下载解包后可以看到：
    \n
    \nManifest:
    \n
    \n    README                - You're reading it now.  
    \n    LICENSE               - A copy of the GPL, under which sneetchalizer is released.  
    \n    CHANGES               - sneetchalizer's cvs/svn commit log.  
    \n    sneetchalizer         - The script itself.  
    \n    sneetchalizer.1       - The manpage for sneetchalizer.  
    \n    sneetchalizer.desktop - A KDE service menu for converting with Konqueror.  
    \n    install.rb            - A quick and dirty script to install the sneetchalizer.  
    \n
    \n
    \n如果有root权限，可以直接运行install.rb，其会将sneetchalizer拷贝到/usr/bin下，将sneetchalizer.1拷贝到/usr/share/man/man1下。
    \n\n
    2、参数解释
    \n\n
    不翻译了，都挺简单明了的，如下：
    \n
    \nXML/HTML代码
    \n
    \n    General options:  
    \n      
    \n    -h or --help  
    \n        Print quick or full usage details respectively.  
    \n    -r or --recursive  
    \n        Search directory arguments recursively for files to convert.  
    \n    -d or --delete  
    \n        delete input files after successful conversion. May not be safe yet!!!  
    \n    -v or --verbose  
    \n        makes sneetchalizer more chatty.  
    \n    -s or --show-output  
    \n        shows output from conversion tool.  
    \n    -p or --pretend  
    \n        don't convert anything. sneetchalizer will go through the motions and print out the commands it would run. Useful for preview- ing a complex command line to ensure it does what you intend. You should interpret this option's output with a grain of salt. For example, if you include the '--sanitize' option, the files will not really be renamed when using --pretend, and as such the command's output will not reflect that the filenames would be changed during an actual run.  
    \n    -t or --terminate  
    \n        terminate sneetchalizer options. This is useful if you have to convert '--coolDir' or '-groovySong.mp3'. This is the only option whose order on the command line is significant.  
    \n    -D ARG or --out-directory=ARG  
    \n        write all outfiles to a directory argument. This is useful if you want to (re)encode files directly to a mounted portable device.  
    \n    --strict and --pedantic  
    \n        many errors that sneetchalizer may encounter are recoverable, such as specifying a directory as argument that contains no files to convert, or conversion failures in general. By default the script will print an error message and move on to the next file. If you use '--strict' then sneetchalizer will bail out at the first sign of trouble except for tag errors. With '--pedantic' the script will stop even on tag errors.   
    \n    --stasis  
    \n        Preserve timestamp (mtime) of original file.  
    \n    --threads [N]  
    \n        Experimental. Use threads to create concurrent jobs. This option takes an optional integer argument which represents the number of threads to launch. The default is two. Preliminary tests suggest there is little advantage (and even diminishing returns) when setting this number greater than the number of cores/CPUs you have. Due to the asychronous nature of threads the --verbose and --show-output flags will be silently disabled and most screen output is supressed.   
    \n    --sanitize  
    \n        Removes ,, ;, :, ', ", %, @, #, and ` from filenames and tags.  
    \n    -n [FORMAT] or --rename[=FORMAT]  
    \n        rename all outfiles (and temporary wavs) according to FORMAT. FORMAT is a string with special designators to be pulled from the file tags. The following options are available:  
    \n      
    \n            * %t Song title  
    \n            * %b Album title  
    \n            * %n Track number  
    \n            * %a Artist name  
    \n            * %y Year  
    \n            * %g Genre  
    \n            * %c Comment field  
    \n      
    \n        Directories may be created with this command, as in "%b/%n - %t". The default value of FORMAT is "%n %t".   
    \n      
    \n    Bitrate/Quality/Compression options:  
    \n      
    \n    -b or --bitrate  
    \n        mp3/ogg/m4a bitrate.  
    \n    -q or --quality  
    \n        mp3/ogg quality.  
    \n      
    \n    quality and bitrate are passed directly to lame or oggenc depending on mp3 or ogg output format respectively. Both tools can handle either a bitrate or quality argument, so it is important to understand what values are valid for the underlying tool in your specific use case. faac will accept a bitrate argument, but not a quality argument. These options will be silently ignored for any output formats other than mp3, ogg or m4a. Make sure you know what you are doing if you decide to use both in one run, and read each tools manpage for valid values. If these options are omitted the tools builtin defaults are used (-q3 for oggenc and -q5 for lame).  
    \n      
    \n    -c or --compression  
    \n        flac/mac compression level.  
    \n      
    \n    this option allows you to pass a compression argument to flac and mac. See 'flac --help' and/or 'mac --help' if you don't know what this means.  
    \n      
    \n    Format Options:  
    \n      
    \n    --out=format  
    \n        output format. Default is wav.  
    \n    --in=format[,format..]  
    \n        input format(s). Default is wav.  
    \n      
    \n    Valid output formats are: "aac", "aif", "aifc", "aiff", "aiffc", "ape", "au", "cdr", "cdda", "copy", "flac", "m4a", "m4b", "mpc", "mp4", "mpp", "mp3", "mp2", "ofr", "ofs", "ogg", "snd", "spx", "tta", "wav", "wv". Valid input formats are all of the above plus "wma". You can specify multiple input formats using a comma: 'mp3,m4a,wma'. Input format is only neccesary when passing directory arguments, as file arguments are handled by context (read: file extension). The "copy" output option copies files directly, bypassing decoding/encoding steps (useful in conjunction with --rename).  
    \n      
    \n    Tagging Options:  
    \n      
    \n    --tt or --title  
    \n        Set 'title' tag.  
    \n    --ta or --artist  
    \n        Set 'artist' tag.  
    \n    --tl or --album  
    \n        Set 'album' tag.  
    \n    --ty or --year  
    \n        Set 'year' tag.  
    \n    --tc or --comment  
    \n        Set 'comment' tag.  
    \n    --tg or --genre  
    \n        Set 'genre' tag.  
    \n    --tn or --trackn  
    \n        Set 'track number' tag.  
    \n      
    \n    The short and long versions are different in an important way: Using the long version will clobber any existing tags. The short version will only set the tag if the existing tag has no value. Note that these tags will be placed in _every_ outfile during the run.  
    \n      
    \n    Alternative Encoder/Decoder Options:  
    \n      
    \n    --gogo  
    \n        use gogo to encode mp3 files.  
    \n    --bladeenc  
    \n        use bladeenc to encode mp3 files.  
    \n      
    \n    The default is still 'lame'. If 'lame' is not found, the script will search for one of these two encoders regardless if these options are passed or not.  
    \n      
    \n    Special Options:  
    \n      
    \n    --in-optionhook=ARG  
    \n        add ARG to infile conversion command. Possibly dangerous!  
    \n    --out-optionhook=ARG  
    \n        add ARG to outfile conversion command. Possibly dangerous!   
    \n

    \n\n
    3、使用示例
    \n\n
    如下简要的写几个使用的示例：
    \n
    \n使用示例：
    \n
    \n    $ sneetchalizer song.mp3  
    \n      
    \n    The most simple possible example, creates 'song.wav'.  
    \n      
    \n    $ sneetchalizer --out=ogg --in=flac -q5 /some/music/dir  
    \n      
    \n    This example converts every flac file in '/some/music/dir' to ogg format at quality 5.  
    \n      
    \n    $ sneetchalizer -d --out=mp3 --in=ogg,m4a,wma -b 160 .  
    \n      
    \n    Converts every ogg, m4a, and wma file in the current directory to a 160 kbps constant bitrate mp3 file. The original files are deleted.  
    \n      
    \n    $ sneetchalizer --out=mp3 --out-optionhook="--preset extreme" /some/wavs  
    \n      
    \n    Here we encode every wav in '/some/wavs' to mp3 format passing '--preset extreme' directly to lame.  
    \n      
    \n    $ sneetchalizer --in=ogg --out=ogg --quality=1 norvegianWood.ogg /some/more/oggs  
    \n      
    \n    Using the same --in and --out format allows us to resample/encode the file at a different bitrate or quality. Note that this will overwrite the original file so only do this on a copy, or use '-D' to write files to another directory.  
    \n      
    \n    $ sneetchalizer --in=ogg --out=m4a -D /mnt/ipod/ /some/oggs  
    \n      
    \n    Here we re-encode some ogg files to m4a format and write them to our mounted iPod.   
    \n
    \n
    \n4、注意事项
    \n\n
    本脚本只是粘合剂，其他的tool还是需要另外安装的。

    Ruby可以很方便的解析XML格式的文档，目前用的比较多的lib主要有三个，分别是：REXML, Hpricot, libxml-ruby，如下选取两个XML文档，分别使用这三个lib解析，感受下各自的速度和易用性。
    \n一、原料
    \n
    \n    posts.xml – Uses xml element for object (post) and xml attributes for object attributes
    \n    timeline.xml – Uses xml element for object (status) and child xml elements for attributes
    \n
    \n二、解析过程
    \n1、REXML
    \n\n
    Pros: In the standard library
    \nCons: Slow, I don’t like the name

    MYSQL的引擎不是一般的多，这次说到的是MERGE，这个引擎有很多特殊的地方：
    \n
    MERGE引擎类型允许你把许多结构相同的表合并为一个表。然后，你可以执行查询，从多个表返回的结果就像从一个表返回的结果一样。每一个合并的表必须有同样的表定义。
    \n
    \nMERGE存储引擎在下面这种使用场合会最为有用，如果需要把日志纪录不停的录入MySQL数据库，并且每天、每周或者每个月都创建一个单一的表，而且要制作来自多个表的合计查询，MERGE表这时会非常有效。然而，这项功能有局限性。你只能合并MyISAM表而且必须严格遵守相同的表定义的限制。虽然这看起来好像是一个大问题，但是，如果你使用另外一种表类型(例如InnoDB)，这种合并可能就不需要了。
    \n
    其创建方法如下：
    \n
    他将多个表在逻辑上当作一个表来查询。他建立后有两个文件， 
    \n.frm 表结构定义 
    \n.mrg union表的名字清单 
    \n
    \n两个基本表:  
    \nCREATE TABLE TEST_MERGE_1( 
    \nID INT(5) NOT NULL, 
    \nVALUE VARCHAR(100)  NOT NULL, 
    \nPRIMARY KEY(ID) 
    \n) ENGINE=MyISAM DEFAULT CHARSET=utf8 
    \nCREATE TABLE TEST_MERGE_2( 
    \nID INT(5)  NOT NULL, 
    \nVALUE VARCHAR(100) NOT NULL, 
    \nPRIMARY KEY(ID) 
    \n)  ENGINE=MyISAM DEFAULT CHARSET=utf8 
    \n
    \nMERGE表的建立： 
    \nCREATE TABLE TEST_MERGE( 
    \nID INT(5) NOT NULL,  
    \nVALUE VARCHAR(100) NOT NULL, 
    \nPRIMARY KEY(ID) 
    \n) ENGINE=MRG_MyISAM DEFAULT CHARSET=utf8 INSERT_METHOD=LAST UNION=(TEST_MERGE_1,TEST_MERGE_2) ;
    \n

    \n1.  此表类似于SQL中的union机制。 
    \n2. 此表结构必须与基本表完全一致，包括列名、顺序。UNION表必须同属一个DATABASE。 
    \n3.  基本表类型必须是MyISAM。 
    \n4. 可以通过修改.mrg文件来修改MERGE表，每个基本表的名字占一行。注意：修改后要通过FLUSH  TABLES刷新表缓存。 
    \n5. 对基本表的更改可以直接反映在此表上。 
    \n6. INSERT_METHOD的取值可以是： 0 不允许插入 FIRST  插入到UNION中的第一个表 LAST 插入到UNION中的最后一个表。(4.0之后可用) 
    \n7.  定义在它上面的约束没有任何作用，约束是由基本表控制的，例如两个基本表中存在着同样的一个Key值，那么在MERGE表中会有两个一样的Key值。

    \nMERGE引擎类型允许你把许多结构相同的表合并为一个表。然后，你可以执行查询，从多个表返回的结果就像从一个表返回的结果一样。每一个合并的表必须有同样的表定义。
    \n
    \nMERGE存储引擎在下面这种使用场合会最为有用，如果需要把日志纪录不停的录入MySQL数据库，并且每天、每周或者每个月都创建一个单一的表，而且要制作来自多个表的合计查询，MERGE表这时会非常有效。然而，这项功能有局限性。你只能合并MyISAM表而且必须严格遵守相同的表定义的限制。虽然这看起来好像是一个大问题，但是，如果你使用另外一种表类型(例如InnoDB)，这种合并可能就不需要了。
    \n其创建方法如下：
    \n他将多个表在逻辑上当作一个表来查询。他建立后有两个文件， 
    \n.frm 表结构定义 
    \n.mrg union表的名字清单 
    \n
    \n两个基本表:  
    \nCREATE TABLE TEST_MERGE_1( 
    \nID INT(5) NOT NULL, 
    \nVALUE VARCHAR(100)  NOT NULL, 
    \nPRIMARY KEY(ID) 
    \n) ENGINE=MyISAM DEFAULT CHARSET=utf8 
    \nCREATE TABLE TEST_MERGE_2( 
    \nID INT(5)  NOT NULL, 
    \nVALUE VARCHAR(100) NOT NULL, 
    \nPRIMARY KEY(ID) 
    \n)  ENGINE=MyISAM DEFAULT CHARSET=utf8 
    \n
    \nMERGE表的建立： 
    \nCREATE TABLE TEST_MERGE( 
    \nID INT(5) NOT NULL,  
    \nVALUE VARCHAR(100) NOT NULL, 
    \nPRIMARY KEY(ID) 
    \n) ENGINE=MRG_MyISAM DEFAULT CHARSET=utf8 INSERT_METHOD=LAST UNION=(TEST_MERGE_1,TEST_MERGE_2) ;
    \n
    \n1.  此表类似于SQL中的union机制。 
    \n2. 此表结构必须与基本表完全一致，包括列名、顺序。UNION表必须同属一个DATABASE。 
    \n3.  基本表类型必须是MyISAM。 
    \n4. 可以通过修改.mrg文件来修改MERGE表，每个基本表的名字占一行。注意：修改后要通过FLUSH  TABLES刷新表缓存。 
    \n5. 对基本表的更改可以直接反映在此表上。 
    \n6. INSERT_METHOD的取值可以是： 0 不允许插入 FIRST  插入到UNION中的第一个表 LAST 插入到UNION中的最后一个表。(4.0之后可用) 
    \n7.  定义在它上面的约束没有任何作用，约束是由基本表控制的，例如两个基本表中存在着同样的一个Key值，那么在MERGE表中会有两个一样的Key值。

    \n
    memcache的stats命令包括：
    \n
    \n1.        stats  
    \n2.        stats reset  
    \n3.        stats malloc  
    \n4.        stats maps

    \n9.        stats detail [on|off|dump]

    \n
    说说其实现遍历的原理：
    \n
      \n    
    1. telnet到192.168.15.225（局域网测试机器）的memcache服务器;
      2. \n    
    2. 执行stats items命令，可以看到出现 很多的items行。
      3. \n    
    3. 执行stats cachedump 3 0命令。这里的3表示上面图中items后面的数字，0标示显示全部的数据，如果是1就标示只显示1条。 
      \n    下图为执行后的结果，item后面的字符串为key
      4. \n    
    4.  通过上面列出的key我们就可以遍历所有的数据了，下面我们取出某一条数据，key为Uc!uLh的数据。

    做web开发的都知道用户上传大文件（比如照片，MP3等）需求有如下难题：
    \n1、文件的存储 -这个不难，买个NAS，规划好目录结构，在mount下就可以了；
    \n
    2、上传速度  --这个问题受限与用户带宽、服务器带宽以及服务器的处理时间，用户带宽无法控制，服务器端的带宽需要监控下，只要未达到上限，也不存在问题；还存在的一个问题就是服务器的处理。
    \n
    3、服务端处理 --这个处理包括请求的接收，文件的校验、存放等，如果文件比较大，在Rails中或许就存在一些问题，请求到web服务器，如Nginx后，达到其设定的缓存大小就发给后端的Rails，这样就会占一个链接直到处理完毕，而后端的thin或者其他的app服务器一共就那么点并发，导致上传比较频繁的时候，压力很大。
    \n
    一个比较不错的解决方案是使用Nginx的upload module，其用C编写的，其处理完上传后，将文件存在在设定的临时目录中，然后将文件路径和你设定的一次哦参数透传给后端的Rails；再用Rails处理一些基本的信息，返回处理结果就可以了，如此一个请求的处理时间也就10ms的样子，开2个thin就可以承受很大的压力了。
    \n
    这个实现还是挺简单，需要注意的upload module非默认的Nginx的module，需要另外下载和编译进去，另外还要注意文件存放的临时文件名可能出现同名的现象，在存取的时候需要留意下。

    \n
    Erlang概述
    \n
    \nErlang不但是一种编程语言，而且它具有比编程语言更加贴近操作系统的一些特性：并发线程、作业调度、内存管理、分布式、网络化等。据说使用Erlang编写的Yaws Web服务器，其并发性能是apache的15倍！（这个没啥好炫耀的吧～）
    \n
    \n这个Erlang初始开源版本包含了Erlang的实现，同时它也是用于构建分布式高可用性系统的Ericsson中间件的最大组成部分。
    \n
    \nErlang具有以下特性：
    \n
    \n并发性 - Erlang具有超强的轻量级进程，这种进程对内存的需求是动态变化的，并且它没有共享内存和通过异步消息传送的通讯。Erlang支持超大量级的并发线程，并且不需要操作系统具有并发机制。
    \n
    \n分布式 - Erlang被设计用于运行在分布式环境下。一个Erlang虚拟机被成为Erlang节点。一个分布式Erlang系统是多个Erlang节点组成的网络（通常每个处理器被作为一个节点）。一个Erlang节点能够创建运行在其它节点上的并行线程，而其它节点可以使用其它操作系统。线程依赖不同节点之间的通讯，这完全和它依赖于单一节点一样。
    \n
    \n健壮性 - Erlang具有多种基本的错误检测能力，它们能够用于构建容错系统。例如，进程能够监控其它进程的状态和活动，甚至这些进程是在其它节点上执行。在分布式系统中的线程能够配置为在其它节点故障的情况下自动进行故障恢复，并在故障节点恢复时自动迁移回到恢复节点。
    \n
    \n软实时性 - Erlang支持可编程的“软”实时系统，这种系统需要反应时间在毫秒级。而在这种系统中，长时间的垃圾收集（garbage collection）延迟是无法接受的，因此Erlang使用了递增式垃圾收集技术。
    \n
    \n热代码升级 - 一些系统不能够由于软件维护而停止运行。Erlang允许程序代码在运行系统中被修改。旧代码能被逐步淘汰而后被新代码替换。在此过渡期间，新旧代码是共存的。这也使得安装bug补丁、在运行系统上升级而不干扰系统操作成为了可能。
    \n
    \n递增式代码装载 - 用户能够控制代码如何被装载的细节。在嵌入式系统中，所有代码通常是在启动时就被完全装载。而在开发系统中，代码是按需装载的，甚至在系统运行时被装载的。如果测试到了未覆盖的bug，那么只有具有bug的代码需要被替换。
    \n
    \n外部接口 - Erlang进程与外部世界之间的通讯使用和在Erlang进程之间相同的消息传送机制。这种机制被用于和操作系统通讯、与其它语言编写的程序交互。如果出于高效率的需要，这种机制的一个特殊版本也允许例如C程序这样的代码直接链接到Erlang运行时系统中来。

    Q:how to get distance between two GeoPoints in sdk 1.0 ? MapPoint.distanceSquared(MapPoint) is gone \"Sad\"

    A:you'll need to brush up on your trigonometry, and first compute the Haversine function (this is the standard way of doing it). In order to use the Java trig functions, you'll have to first convert all your angles from degrees to radians. 
    \nGiven two longitude/latitude pairs, and the earth's average radius (assume 6356.78km for your calculations), 
    \nyou can calculate the distance between the 2 points via this Java code: 
    \n
    \n     \tdouble EarthRad = 6356.78;\t// in km ! 
    \n// first convert to radians... 
    \ndouble geo1_lat = geo1.getLatitude()*java.lang.Math.PI/360; 
    \ndouble geo1_lng = geo1.getLongitude()*java.lang.Math.PI/360; 
    \ndouble geo2_lat = geo2.getLatitude()*java.lang.Math.PI/360; 
    \ndouble geo2_lng = geo2.getLongitude()*java.lang.Math.PI/360; 
    \n
    \ndouble deltaLat = java.lang.Math.abs(java.lang.Math.abs(geo2_lat) - java.lang.Math.abs(geo1_lat)); 
    \ndouble deltaLng = java.lang.Math.abs(java.lang.Math.abs(geo2_lng) - java.lang.Math.abs(geo1_lng)); 
    \n
    \ndouble dist = 2*EarthRad*java.lang.Math.asin(java.lang.Math.sqrt(haversine(deltaLat) 
    \n+ java.lang.Math.cos(pair1_lat) 
    \n*java.lang.Math.cos(pair1_lng)*haversine(deltaLng))); 
    \n
    \nWhere "dist" now contains the distance between along the earth's surface. 
    \nYou can find the Haversine function trig equation by Googling it, then construct a method that returns the appropriate value.
    \n
    Computing the speed is straightforward: you know your sampling frequency, and you now know the distance between the most recent two points, so, employee speed = distance / sampling interval

    在Android中使用GoogleMap非常方便，但是有些小技巧或者注意事项你必须牢记，否则调试半天你也不会找到啥线索，浪费时间不说，更让你狂抓，以下技巧都是我在实际项目中遇到的，不断更新和维护，如果你有类似技巧，欢迎分享：
    \n
    （以下技巧是基于SDK 1.0的）
    \n
    一、申请Apikey，并放在正确的位置
    \n
    这个应该都知道，但是是申请得到的key放哪里很多人不知道，可以放在
    \n
    1、XML布局文件中
    \n
    <view android:id="@+id/mv"
    \n   class="com.google.android.maps.MapView"
    \n   android:layout_width="fill_parent"
    \n   android:layout_height="fill_parent"
    \n   android:layout_weight="1" 
    \n   android:apiKey="01Yu9W3X3vbpYT3x33chPXXX7U1Z6jy8WYZXNFA" 
    \n   />
    \n
    2、java中
    \n
            mMapView = new MapView(this, "01Yu9W3X3vbpYT3x33chPxxx7U1Z6jy8WYZXNFA");
    \n
    二、记得导入uses-library 
    \n
     由于1.0版本的修改，使得map包不再是默认的了，使用的时候需要在manifest中的application节点下加入
    \n
    <uses-library android:name="com.google.android.maps" /> 
    \n
    \n
    否则，你将遇到可恶的“java.lang.NoClassDefFoundError: ”，切记！
    \n
    三、需要给予一定的权限
    \n
    因为要使用GoogleMAP的service，所以需要
    \n<uses-permission android:name="android.permission.INTERNET"></uses-permission>
    \n
    如果需要GPS等应用，还需要
    \n
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
    \n
    四、Activity需要继承自MapActivity
    \n
    类似如下代码；
    \n
    package com.iceskysl.showmap;
    \n
    \nimport com.google.android.maps.MapActivity;
    \n
    \nimport android.os.Bundle;
    \n
    \npublic class ShowMap extends MapActivity {
    \n    /** Called when the activity is first created. */
    \n    @Override
    \n    public void onCreate(Bundle savedInstanceState) {
    \n        super.onCreate(savedInstanceState);
    \n        setContentView(R.layout.main);
    \n    }
    \n
    \n    @Override
    \n    protected boolean isRouteDisplayed() {
    \n        // TODO Auto-generated method stub
    \n        return false;
    \n    }

    \n
  • Use cloud storage for static files. --S3,I do not care it 's fine in china.
    • \n
  • Use HTTP Cache Control to tell the browser what it can cache.  --this is true,etag is great.
    • \n
  • Use Sphinx for text search.  --sometimes,you do have others chose.
    • \n
  • Use InnoDB for more crash resistant and faster writes.  --maybe it's right.
    • \n
  • Don't use textbook Rails ActiveRecord objects. Use New Relic to find exactly what is slow in your system. --yep
    • \n
  • Use memcache later so you find your database bottlenecks now. --this is very important.
    • \n
  • Use mongrel proctitle to find your slow queries. You are only as fast as your slowest queries. -maybe mongrel is not only chose,think about thin,ok?
    • \n
  • Use asynchronous job queuing to do work in parallel.  --yes,but sometimes crontab is enough.
    • \n
  • Use monitoring so you'll know when your site went down and why. --that's it,just do it.
    • \n
  • Learn by reading the source code, fixing problems, and submitting them back to the community.  --very userfull when you got some strange questions..
    • \n
  • Use new plugins. Old plugins can't be trusted. --and check chang histroy carefully.
    • \n
  • Use new information. Old information can't be trusted.  --and what's this?

    \n1.DYNAMICALLY LOADING CONFIG FILES INTO AN ALREADY RUNNING GOD
    \n
    \n
    God allows you to load or reload configurations into an already running instance. There are a few things to consider when doing this:
    \n
      \n    
    • Existng Watches with the same name``` as the incoming Watches will be overidden by the new config.
      • \n    
    • All paths must be either absolute or relative to the path from which god was started.
      • \n
    \n
    To load a config into a running god, issue the following command:
    \n
    $ sudo god load path/to/config.god
    # god load /data/www/api/config/config_thin_api.god```\n
    Config files that are loaded dynamically can contain anything that a normal config file contains, however, global options such as God.pid_file_directory``` blocks will be ignored (and produce a warning in the logs).

    \n\n
    本书的撰写过程得益Google自身的很多服务，比如Google Doc，Google Group等等，在撰写的过程中，可以非常顺利、自然、流畅的协作。
    \n\n
    《Google API大全：编程·开发·实例》这本书是国内的第一本较为完整的介绍Google API的书，内容囊括了所有主要的Google API，并用大量的实例展示了Google API的应用方法。想更快的了解这些强大的API，本书无疑是个很好的枕边书。

    \n

    \n

    wow，千万级的，看来够大，这个没啥用，先备份下数据文件，然后truncate掉
    \n
    mysql> truncate table  rails_logs_081023;
    \n
    ERROR 1105 (HY000): MyISAM table 'rails_logs_081023' is in use (most likely by a MERGE table). Try FLUSH TABLES.
    \n
    \n
    出错了，这边表貌似被MERGE用了，查了一下，果然是被rails_logs这个表MERGE着用了，那我直接truncate这个rails_logs试试看。
    \n
    mysql> truncate table  rails_logs;
    \n
    ERROR 1 (HY000): Can't create/write to file './iceskysl_beta_log/rails_logs.MRG' (Errcode: 17)
    \n
    \n
    呀，还是出错，文件不可写？Errcode: 17
    \n
    查下资料，原来：
    \n
    System error: 17 = File exists
    \n
    \n
    这咋回事，再查资料，原来.MRG是创建MERGE表的时候创建的，已经存在了。
    \n
    \n
    那就先把这个MERGE表干掉，再创建：
    \n
    先看下这个表是咋定义的：
    \n
    mysql>  show create table rails_logs;
    \n
    \n
    记录下SQL，接着drop掉。
    \n
    mysql> DROP  table rails_logs;
    \n
    Query OK, 0 rows affected (0.36 sec)
    \n
    \n
    再truncate我的目标表
    \n
    mysql> truncate table  rails_logs_081023;
    \n
    Query OK, 0 rows affected (4.22 sec)
    \n
    \n
    \n
    够快的，11042292条数据4S搞定，接着再创建下这个MERGE表，执行下上面记录的SQL就好了。
    \n
    \n
    最后确认下这表没啥问题：
    \n
    \n
    mysql> select count(id) from rails_logs;
    \n
    +-----------+
    \n
    | count(id) |
    \n
    +-----------+
    \n
    |         0 |
    \n
    +-----------+
    \n
    1 row in set (0.00 sec)
    \n
    \n
    OK，搞定，空间有了，天下太平了。

    \n
    问题：有一个拥有1亿条数据的表，只需要保留其中的5条，其他删除，如何做？
    \n
    这就需要用truncate table来搞定了，如下：
    \n
    select 5条数据 into #临时表 from 1亿条数据的牛X表
    \n
    truncate table 1亿条数据的牛X表
    \n
    --让它牛X，不到10毫秒干掉它。

    drop table #临时表

    在项目里用了memcached和cache_fu，其默认的 get_cache(id)还是非常方便的，但是对于另外一个用的比较多的find_by_xx这样的，貌似没看到有现成的方法可以使用。

    This is for a large system with memory = 512M where the system runs mainly

    MySQL.
    \n\n
    You can copy this file to
    \n\n
    /etc/my.cnf to set global options,
    \n\n
    mysql-data-dir/my.cnf to set server-specific options (in this

    ~/.my.cnf to set user-specific options.
    \n\n
    In this file, you can use all long options that a program supports.
    \n\n
    If you want to know which options a program supports, run the program
    \n\n
    with the "--help" option.
    \n\n
    The following options will be passed to all MySQL clients
    \n\n

    \n\n
    那么应该怎样来配置成我喜欢的颜色呢？下面我们就来详细说一些这些配置。
    \n\n
    ~/.bash_profile是bash shell中当前登录用户的配置文件。bash是“终端”中默认的shell。
    \n\n
    alias ls=”ls -G”是给”ls -G”起了一个别名，当执行ls时，就相当于执行了ls -G。
    \n\n
    CLICOLOR是用来设置是否进行颜色的显示。CLI是Command Line Interface的缩写。
    \nLSCOLORS是用来设置当CLICOLOR被启用后，各种文件类型的颜色。LSCOLORS的值中每两个字母为一组，分别设置某个文件类型的文字颜色和背景颜色。LSCOLORS中一共11组颜色设置，按照先后顺序，分别对以下的文件类型进行设置：
    \n\n
    directory
    \nsymbolic link
    \nsocket
    \npipe
    \nexecutable
    \nblock special
    \ncharacter special
    \nexecutable with setuid bit set
    \nexecutable with setgid bit set
    \ndirectory writable to others, with sticky bit
    \ndirectory writable to others, without sticky bit
    \nLSCOLORS中，字母代表的颜色如下：
    \n\n
    a 黑色
    \nb 红色
    \nc 绿色
    \nd 棕色
    \ne 蓝色
    \nf 洋红色
    \ng 青色
    \nh 浅灰色
    \nA 黑色粗体
    \nB 红色粗体
    \nC 绿色粗体
    \nD 棕色粗体
    \nE 蓝色粗体
    \nF 洋红色粗体
    \nG 青色粗体
    \nH 浅灰色粗体
    \nx 系统默认颜色
    \n所以，如果我们想把目录显示成红色，就可以把LSCOLORS设置为bxfxaxdxcxegedabagacad就可以了

    一个项目用到了图片上传，不想自己写处理过程了，于是就找找可以使用的插件，看到了Paperclip，大概了看了下代码和使用介绍，比较简洁。
    \n\n
    装上测试了下，整个过程比较顺利，很快就集成了需要的功能，但是具体到我的需求 上，花了点时间，我的需求也比较常见，就是大量的图片不能就存在一个文件夹下（否则这么多的小文件会带来很多的隐患），于是看代码找找其是否支持分目录的方案，我直接基本上都是按时间来分成诸如"2010/0428/"这样的目录，但是找了一圈，发现其提供了timestamp的一个变量，但是其结果比较糟糕，文件夹中还会根据当代的locale出现一些等下，不太合适；
    \n\n
    然后看到其提供了一个：id_partition的参数，其意思是：
    \n# Returns the id of the instance in a split path form. e.g. returns
    \n\n
    000/001/234 for an id of 1234.
    \n\n
    和我预期的差不多，如果决定这个数字还不够，可以修改其代码，如下：
    \n
    \ndef id_partition attachment, style_name
    \n("%09d" % attachment.instance.id).scan(/\\d{3}/).join("/")
    \nend
    \n你可以再加3位（这下应该足够了，千亿级别的了），分成四个等级
    \n
    \ndef id_partition attachment, style_name
    \n("%12d" % attachment.instance.id).scan(/\\d{3}/).join("/")
    \nend
    \n
    \n
    \n然后我们可以按照这个方式专辑实现安装日期类分目录的，代码如下：
    \n
    \n# Returns the timestamp of the instance in a split path form. e.g. returns
    \n# 2010/0428 for an id of 2010.04.28
    \ndef timestamp_partition attachment, style_name
    \nattachment.instance_read(:updated_at).strftime("%Y/%m%d/")
    \n# ("%09d" % attachment.instance.id).scan(/\\d{3}/).join("/")
    \nend
    \n
    \n然后给model加上：
    \n
    \nhas_attached_file :logo, :styles => {:thumb => '64x64>', :small => "150x150>" },

    今天在GoogleTalk上朋友发来消息，说有人撰写文章指出我以前开发的一款更换手机壁纸的应用（嵌入了admob和google的广告）中存在偷窃用户隐私数据行为时，我简直不敢相信这是真的；当看到新闻的详细内容时，我更是被震惊了。以下是那段转载文章的原话：
    \n\n
    “拉斯维加斯黑帽大会上，Lookout 的安全人员指出，一个伪装成Android手机壁纸应用的偷窃个人信息程序已经被下载了百万次，它会收集您的个人资料，并将其发送到一个来自中国深圳的神秘网站imnet.us中。安全人员(Kevin MaHaffey)估计这款程序是由正常的壁纸应用修改而来，黑客将其上传到Android Market，希望装饰自己手机的用户因此而中招。泄漏的数据包括浏览历史记录，短信，手机的SIM卡号码，用户识别号，语音邮件，甚至是密码，他警告称每个人都应该警惕来自手机上的威胁。”
    \n\n
    在看完这条消息后，我立马检查了所有代码，防止这款应用在我不知情的情况下，被他人加入恶意代码，但我一无所获。
    \n现就相关事宜申明如下：
    \n一、我开发的所有程序都没有侵犯到用户的隐私。
    \n\n
    在这个应用中，申请的全部权限为：
    \n<uses-permission android:name="android.permission.INTERNET" />
    \n<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    \n<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    \n<uses-permission android:name="android.permission.SET_WALLPAPER" />
    \n<uses-permission android:name="android.permission.READ_PHONE_STATE" />
    \n<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    \n懂点Android技术的都知道，这些权限都是为了让该软件的功能，能够正常工作所必须的权限（连接网络，获取网络状态，下载壁纸时读写SD卡，设置壁纸，读取手机状态）和Admob的广告精准推送所需要的权限（位置信息，读取手机状态）。
    \n至于获取用户浏览历史记录、短信、语音邮件密码的这些明显侵犯用户隐私的行为，完全是子虚乌有。一方面并没要申请相关的权限；另一方面我还真不知道怎样获取这些敏感信息。另外，admob的精准广告服务中可能是会针对用户的地理位置等信息推送更准确的广告服务。
    \n关于这款应用能获取的设备标识号是用来区分设备的唯一性，免去用户注册的麻烦，而能给用户提供收藏图片的功能；而诸如获取手机屏幕大小是为了能够智能适配合适的图片。在这些设备信息中，请问哪一条会侵犯到用户的隐私。
    \n另外说我可以获取浏览历史信息，这简直就是个天大的笑话。如果懂一点程序的就会知道，要获取浏览器信息必须在程序里申请com.android.browser.permission.READ_HISTORY_BOOKMARKS权限。我的程序完全没有获取到权限，怎么能够获取到历史信息，真是笑话！！！
    \n\n
    二、Android手机的权限管理，在任何没有刷过第三方rom的手机上是很严格的。
    \n Android手机的权限管理，在任何没有刷过第三方rom的手机上是很严格的，在没有相关权限的情况下，要获取那些信息，是完全不可能的。就算是被刷过Rom的手机，也只有具有该ROM制作人的加密签名的程序，才能完成一些不安全的操作。
    \n我所需要的权限在用户安装的时候会很明确的告诉用户，下面我就给大家展示一下我应用申请的权限和另外一个著名的壁纸的应用background和一款管理短信的应用申请的权限。
    \n\n
    我的软件需要的权限：
    \n\n
    看看background（另外一款壁纸的应用）申请的权限：
    \n\n
    Handcent SMS申请的权限：
    \n\n\n
    短信有短信的权限，联系人有联系人的权限，我都没要申请，请问我如何获取相关的信息。
    \n\n
    三、应用主要面向外国用户，但绝对没有获取那些高敏感度的隐私信息！
    \n\n
    该应用主要面向外国用户（国内由于网络原因无法正常使用），连接服务器端能够获取到精确适配终端的图片，这是一款非常有用，也深受用户喜爱的应用。它确实拥有数量众多（几百万）的用户，但绝对没有获取那些高敏感度的隐私信息！我每天都收到很多用户的反馈邮件告诉我这个软件多么棒，给他们带来多少乐趣！
    \n\n
    四、我本人始终与业界同仁一道，希望建立诚实守信、和谐共生的Android产业生态系统。
    \n\n
    随着Android开放性操作平台手机的广泛使用，其应用软件开发市场正呈现蓬勃发展景象。对于提醒用户警惕来自手机上的威胁，我本人向来都是强烈支持的！本人一直始终与业界同仁一道，一直为共建诚实守信、和谐共生的Android产业生态系统而努力，将力量专注于用户需求和技术创新，创造更被用户喜欢的软解，并致力于推动手机应用软件产业持续健康发展。
    \n\n
    在此，本人郑重申明，该应用没有获取任何诸如“浏览历史记录，短信，语音邮件密码等”这种高敏感度的信息，并和国外的原作者取得联系，让其修正自己的言论并发布公开道歉，同时对于这种不负责任的言论和评价观点，对我及与我相关的应用进行不负责任的报道造成的影响给予补偿，我将保留追究其法律责任的权利。
    \n\n

    \nupdate：
    \n写完申明后，去看消息出处看到其竟然做了修改，我早料到其会做相关的行为，所有早些时候截了屏幕如下：
    \n\n\n
    而现在的文章被修改为：
    \n\n\n
    看我用鼠标标识的地方，对关键信息进行了修改，感兴趣的人可以去 http://mobile.venturebeat.com/2010/07/28/android-wallpaper-app-that-steals-your-data-was-downloaded-by-millions/ 查看原文，对于这种标题党用子虚乌有的事情炒作，等消息传播后再修改自己的内容算什么行为！而对国内部分媒体在传播时不但不对真实性进行验证，还添油加醋，歪曲意思的报道，我非常无奈（看到有人还说可以获取信用卡信息，还加密传输，我实在无语）。
    \n\n
    按照我个人的感觉，他们应该紧接着要开始拿这个事件来炒作自己的产品了，我个人懒得去关注，如果有人发现有人借此炒作自己的产品，请帮忙分析分析，看看到底是什么人用这样手法。
    \n\n
    再次update！！！
    \n\n
    通过email和mylookout的人取得联系，说明我取得诸如设备号，手机屏幕大小是为了更智能的给设备适配图片，而获取部分的sim卡号是后来用户反馈说自己换了手机还想使用之前的收藏记录才使用的，这些信息只在该应用中使用，并没提供给任何第三方！
    \n\n
    同时让其确认venturebeat上文章中说到的获取浏览器历史，短信息，密码等高敏感性信息是否是他们说的还是写文章的人自己写的（Lots of my users send me the email ask me why I collect their text message and voicemail passward, I just want to make sure whether you and your ceo said that  I collected browsing history,text message ,voicemail passward during the meeting.）。
    \n\n
    其cto给我回复说他们没有说过我的应用获取过诸如text messages or browsing history这些信息（ We never stated that the wallpaper applications gathered users text messages or browsing history.），是媒体在撰写和传播的时候错误报道了（A member of the press misreported our research and he has since corrected it. ）。
    \n\n
    我非常无语～
    \n\n
    2010年8月4日第二次次update！
    \n\n
    多谢这些天很多朋友的关心，我很好，谢谢！这些天和google android组，lookout公司和venturebeat的作者，以及国内外很多媒体，博客们，记者们都有很多的接触。
    \n\n
    1. google就前段时间将应用暂停和我一起分析了这个应用，今天发来调查的结果：
    \n\n
    Our investigation has concluded that there's no obvious malicious code in your apps, though the implementation accesses data that it doesn't need to.  We've restored your apps (and they'll be available on Market again once you publish them), and are looking forward to seeing them updated to use ANDROID_ID.  We are likely to make a statement about this issue this week--I'll let you know.
    \n\n
    我早就说过，我配合调查，我把代码提供给他们，google也做出了公正的评判，另外也给我提了一些建议（ANDROID_ID）。
    \n\n
    2. 当时写这篇报道的venturebeat记者Dean Takahashi发来了mail，为自己犯的错误道歉，并道歉该事带来的恶劣影响，会再写一篇文章澄清这个事情以消除影响。
    \n\n
    3. 那个安全公司lookout的人写邮件来要于我一起“ We wanted to coordinate with you to prevent further misunderstandings. ”。

    4.好几个不认识的国外记者很负责任，发邮件和gt和我交流询问事情的真相，并帮我喊冤，谢谢这些有职业精神的记者们。

    nginx的upstream目前支持5种方式的分配
    \n\n
    1、轮询（默认）
    \n每个请求按时间顺序逐一分配到不同的后端服务器，如果后端服务器down掉，能自动剔除。
    \n\n
    2、weight
    \n指定轮询几率，weight和访问比率成正比，用于后端服务器性能不均的情况。
    \n例如：
    \n`upstream bakend {
    \nserver 192.168.0.14 weight=10;
    \nserver 192.168.0.15 weight=10;
    \n}
    \n\n
    3、ip_hash 
    \n每个请求按访问ip的hash结果分配，这样每个访客固定访问一个后端服务器，可以解决session的问题。
    \n例如：
    \nupstream bakend {
    \nip_hash;
    \nserver 192.168.0.14:88;
    \nserver 192.168.0.15:80;
    \n}
    \n\n
    4、fair（第三方）
    \n按后端服务器的响应时间来分配请求，响应时间短的优先分配。
    \n`upstream backend {
    \nserver server1;
    \nserver server2;
    \nfair;
    \n}
    \n\n
    5、url_hash（第三方）
    \n按访问url的hash结果来分配请求，使每个url定向到同一个后端服务器，后端服务器为缓存时比较有效。
    \n例：在upstream中加入hash语句，server语句中不能写入weight等其他的参数，hash_method是使用的hash算法<!--more-->
    \n\n
    `upstream backend {
    \nserver squid1:3128;
    \nserver squid2:3128;
    \nhash $request_uri;
    \nhash_method crc32;
    \n}
    \n\n
    tips:
    \n`upstream bakend{#定义负载均衡设备的Ip及设备状态
    \nip_hash;
    \nserver 127.0.0.1:9090 down;
    \nserver 127.0.0.1:8080 weight=2;
    \nserver 127.0.0.1:6060;
    \nserver 127.0.0.1:7070 backup;
    \n}
    \n在需要使用负载均衡的server中增加
    \nproxy_pass http://bakend/;
    \n\n
    每个设备的状态设置为:
    \n1.down 表示单前的server暂时不参与负载
    \n2.weight 默认为1.weight越大，负载的权重就越大。
    \n3.max_fails ：允许请求失败的次数默认为1.当超过最大次数时，返回proxy_next_upstream 模块定义的错误
    \n4.fail_timeout:max_fails次失败后，暂停的时间。
    \n5.backup： 其它所有的非backup机器down或者忙的时候，请求backup机器。所以这台机器压力会最轻。
    \nnginx支持同时设置多组的负载均衡，用来给不用的server来使用。
    \n\n
    client_body_in_file_only 设置为On 可以讲client post过来的数据记录到文件中用来做debug
    \nclient_body_temp_path 设置记录文件的目录 可以设置最多3层目录
    \nlocation 对URL进行匹配.可以进行重定向或者进行新的代理 负载均衡

    \nFile.open("../log/apps.log.\#{LOG_POSTFIX_FOR_YESTERDAY}").each do |line|
    \n3.提取需要的数据
    \nid, apk_id, ip, client_id, channel_id, uniquely_code ,track = line.split(" : ")[1].split(",")
    \n4. 生成sql串
    \nsqlInsert = "INSERT logs_downloads.....balalaalala
    \n5. 写到sql文件里
    \nsqlfile.puts( sqlInsert )
    \n6. 调mysql直接导入sql
    \n里面还有一些数据的清洗和排重工作～
    \n每天的日志文件差不多500w行，解析生成sql的过程不理想（其中没用数据库操作）～ 难道是我磁盘性能很糟糕～～
    \n过程看到基本上都没问题，无外乎解析文件，写文件的操作，不应该慢成这样的，最后把目光放在了数据的清洗和排重工作种，这个过程是想在入库的时候就把一些虚假的量排除掉，于是我们自己设计了一个算法来过滤，算法的逻辑很简单，根据一些参赛md5出一个key，然后把这个key丢在Array中，然后用include?来判断这个key是否已经存在，问题就出在这里！
    \n\n
    ruby的Array中的include?是需要很小心的，我之前想当然的认为这个方法应该很快，也没仔细看就用了，结果发现问题就在这个方法上，直接上下源码看看：
    \n
    \n当看到:
    \n`
    \nfor (i=0; i #blalalal
    \n}
    \n
    \n\n
    这个的时候我就明白了，果然，这个方法直接遍历Array，然后你可以想想当我有个500w大小的Array的时候，再用include?是何等的情景啦～
    \n修改方案很容易了，改用hash就好了，不多说～～

    其实我的需求蛮简单的，大概如下：
    \n1. 需要支持快捷键（最好是手不离开键盘能完成全部操作，或者是纪录，整理list的主要工作）
    \n2. 需要支持子任务（最好是不限制级的，目前能用到3级别）
    \n3. 界面简洁，再简洁
    \n4. 支持多端访问，至少在电脑和手机（android&iphone)可以使用
    \n5. 可以打印或者email给朋友
    \n\n
    最终还是回到了Google Task，经过一段时间的使用，我现在已经非常喜欢Google Task，也给我的效率带来很大帮助，我可以把我的方式分享下。
    \n1. 每天开电脑的第一件事情就是开gmail，处理完邮件开始工作，顺手把gmail里把Google Task打开，并pop up出一个单独的窗口，拖拉到合适的大小；（我工作的时候是两个显示器，就把这个窗口一直放在外接显示器的边上，抬眼可见）
    \n2. 每周一个list，名字是时间范围，比如2012.02.06－2012.02.12；
    \n3. 周一的时候会尽量把本周要做的事情列进去（按照事情的类型或者项目，比如公司事务，eoemarket相关），再把要做的事情一个一个输入进去，Google Task的输入很方便，用好tab键和shift tab键来调整层级；用好Ctrl + Up和Ctrl + Down来调整顺序，用Shift + Enter进入到具体的事情中撰写详细，写完再Shift + Enter回到列表；
    \n4. 每次做事情的时候，可以用Tab再细分，一个一个执行掉；完成后回到Google Task，用Option + Enter 标识这个完成（Option + Enter这个快捷键在官方帮助文档和tips里都没，我自己找出来的，mac电脑）；另外勾选上级条目可以把下级条目都标记完成～
    \n5. 每次遇到新的事情直接添加进去，经常review，如此反复就好了～
    \n6. 有的时候还通过打印和发送邮件通知其他人我都做了什么；
    \n\n
    此外，Google Task提供如下方式的使用，我个人觉得足够了
    \n1. gmail中集成/igoogle集成
    \n2. iphone客户端，android客户端（第三方开发的）
    \n3. chrome插件
    \n4. 桌面客户端（没找到，也不怎么用）
    \n5. api接口（或者自己写）
    \n\n
    如果硬说还可以有些期待的话，我的是这样的：
    \n1. 谁写个更好用的iphone客户端（现在app store上的质量一般，而且收费，哪天我心血来潮我来写一个去～）
    \n2. 可以把一个list里没完成的复制到另外一个list中
    \n3. 真木了
    \n\n
    我的个人建议是：必须用好快捷键！
    \n\n
    希望我的这篇介绍能让你喜欢Google Task，并对自己有所帮助
    \n如果你有兴趣，可以看看它的官方帮助页面

    \n\n
    记忆中我们的eoeAndroid已经经过了这么几个阶段
    \n\n
    第一阶段：这是个大家庭（2009年）
    \n社区创建之初，android在国内还很不活跃，社区人数不多，仅有几个好朋友开始活跃，开始摸索android是个什么，可以做什么，社区人不多，但是大家都蛮熟悉，社区象一个大家庭，大家经常熬夜研究文档，代码，试验。
    \n\n
    第二阶段：曲折的发展之路（2010年）
    \n到了2010年前后，有了第二批做android的人，社区得到大家的认可和口碑相传，很快服务器就开始吃紧，开始不稳定，那会服务器还托管在上海一个机房，而后就遭受其他网站的牵连，机房被封，服务器被拔线，几经折腾，后来索性搬迁到国外，虽然一些地方速度慢一些，但是终于稳定了；这段时间很曲折，在国内换从上海换到成都，又换到北京，险些万劫不复，幸好那会备份转移做的比较勤，只丢了一点点数据，万幸！
    \n\n
    第三阶段：蓬勃发展，开拓思路（2011年）
    \n迁往国外后的一段日子，android终于爆发了，开发者数量也开始爆发了，越来越多的人加入android技术阵营，社区一次一次的加带宽，加内存，加磁盘，一次一次的升级，优化，最后我们再次迁回国内，有了自己的机房和专属服务器；社区也做过一次大的升级成开发者门户，想给大家提供更多的内容。
    \n\n
    第四阶段：新起点，新目标
    \n2011底，我们酝酿新的改版，我们一直在思考如何把eoeAndroid社区做好，让更多的人得到帮助，让更多的人踏入android行业的大门；我们设计和讨论过n多方案，最终我们选择的方向是“[color=Red]源于内心，回归更纯粹的技术[/color]”，或许是因为技术出身，对技术有着特殊的感情，我们觉得eoeAndroid一直都有这么一些精神：专业 专注 自由 开放 分享 。我们大家都专注android技术领域，都是专业的人才，我们会积累沉淀好的资源和文章，用心运营；我们也崇尚自由的氛围，开放的态度，乐于分享我们的经验和知识。

    2. 直接写，示范代码如下
    \nf = File.open("foo.xml", "w")
    \nf.puts("<?xml version=\\"1.0\\" encoding=\\"gbk\\"?>")
    \nf.puts('')

    \nreal    0m0.974s
    \nuser    0m0.813s
    \nsys 0m0.063s

    有些人可能对我多少有些了解，应该算国内第一批开始搞android相关的人，09年创办的android开发社区（eoeandroid.com）现在也是国内android开发人员最活跃的社区，我写过一些代码，也写过一些技术的文章，也做过android应用，也见过很多android的技术，也给公司（eoe）招了不少android技术人员，也给不少朋友奇特推荐过android技术的人，我下面会分享我对android技术人员招聘的一些看法。
    \n\n
    1. 首先看为人：品性很重要
    \n\n
    或许是因为我们是创业公司，会严格选择每一个进来的人，特别是技术的人。技术很重要，但是在我这边不是第一位的，人品和性格是第一的，创业公司唯一不变的就是变化，如果人品不过关的人肯定待不住，如果性格合不来的人肯定待不久。有人说这个很虚，见一面怎么可能看出品性，其实不难，一举一动，言语措辞都很简单就可以看出一个人的内在（因为技术的人为人真的很简单），所以，如果你去面熟，表现真实的自己，对公司，对个人都是有好处的，合得来就是合得来，合不来强求也没用，这本是个双向选择的事情，不存在谁强势谁弱势。积极，主动，自信，阳光是比较好的品格～
    \n\n
    2. 接着看技术：基本功需要有体系，够扎实，思维要跳跃
    \n\n
    如果来eoe面试过的人应该知道，我们面android有一套笔试题，但是java的，很多人不理解可能会问我来面android的为啥让我做java的题？其实很简单，java是基础，我们的笔试题会涉及到基础的，算法的，开放性的试题，我们需要全面的了解一个人。每个题目都很重要，所以，如果去面试，如果对方是精心设计的题，请认真一点回答，记住认真不是死板，答题看的是基础和思维，细节无所谓，因为有真正干活的时候有google，有api～
    \n\n
    3. 然后看经验：经验很重要，你必须对你做过的项目了如指掌
    \n\n
    做完题目，我们一般就正式面试了，会问问笔试题目上你的感觉和具体一个问题的思路，然后才开始问之前的经验，我们的要求是必须真正做过项目，如果没项目，应用也行，其实需要的就是一个关键点：你真正操作过一个应用，对你做过的模块必须了如指掌，我们不会问太多项目，让你一个最熟悉的或者最喜欢的项目，问的很细节，细节到你证明这个项目自己之前是用心做的，或者证明你在这个项目就是个打酱油的。
    \n\n
    然后会问点和android相关的东西，一般容易的，中等的和比较刁钻的问题都会问一些，刁钻的比如会问你现场保护的机制，方式，为什么要现场保护等等问题，如果你是个做技术爱思考的人，这些问题应该不难，如果你虽然做过1－2年android，但是每个方面都很泛泛，那你肯定会被问的傻傻的。
    \n\n
    最后会问一些开放性的问题，都是很随机的题目，比如桌子上的一个杯子等等都可能会被问～～这个地方主要看整体的思维和分析问题的能力。
    \n\n
    4. 做决定：合适还是不合适，或者留题目，做个小测试
    \n\n
    如此过程，我们基本上就能判断一个人是否符合我们要求，如果不满足，我们基本会很直接告诉原因是什么，哪个地方我们觉得不合适，你以后应该注意什么？如果我们觉得满足预期，可能就收了；如果我们拿不准，但是觉得你潜力很好，可能会留个题目，做个小东西，不会很难，做的时候请注意自己的编码风格，整体项目结构等等，这些是关键因素～
    \n\n
    如上过程，就是我在招android技术人员的一些思路和过程，我们是创业公司，相对看的更全面的能力，但是我个人觉得企业的思维或许都差不多，如果你要找android相关的工作，请参考～
    \n\n
    另外，android开发社区 里有很多企业招聘android技术人员，大家可以多关注，希望大家能找到自己满意android工作～记得经常来android开发社区活动～
    \n\n
    再顺便提一下，我们（eoe）长期招合适的android技术，如果你有兴趣，可以联系我～

    这本书当时写的还是比较匆忙的，主要是针对android入门开发者的，很多地方也写的不仔细，比如代码有点多，代码没有很好的格式化，内容偏简单，系统化不够等等～ 书中的例子也有点比较老了，例如yobo的api已经不能使用了，豆瓣的api也有了更新等等～每次读者在社区问书上一些问题的时候，我都觉得蛮愧疚的，毕竟内容比较老，会误导一些读者～
    \n\n
    这本书是国内第一本android的技术的书，当时的android sdk还是1.5版，上市快3年了，内容相对偏老的，出版社一再催我能更新到最新的sdk版本，再把之前用户反馈比较多的问题完善下～是不是真的需要抽点时间来出第二版了呢？
