Archive for the 'Programming' CategoryIt took me a while to find out how to perform programmatic login using repoze.who.here is the source code:
rememberer = request.environ['repoze.who.plugins']['cookie']
identity = {'repoze.who.userid': user.username}
response.headerlist = response.headerlist + \
rememberer.remember(request.environ, identity)
No words can express how much I love you from the day you were born until now,you have held a special place in my heart, one that is irreplaceable and invaluable.
Happy birthday, My sweet little EQ.
很多应用都需要高性能的多关键词搜索功能，网络”扫黄”开始后更是如此，如何在文本内容中快速地搜索出敏感关键字变得越来越重要。
Wu-Manber算法是一个不错的解决方案，尤其是针对包含有大量关键词的搜索。Wu-Manber算法的C语言实现非常丰富，为了方便如C#，VB.net等编程语言使用该算法，我用C/C++写了一个基于改进的Wu-Manber算法的多关键词搜索组件：wu-manber-com。
使用方法
以vb.net/c#为例，使用前，先运行regsvr32 stringsearch.dll注册该组件，然后将stringsearch.dll添加到项目引用中。调用示例代码如下：
StringSearchLib.WuManber s = new StringSearchLib.WuManber();
s.AddPatterns("keyword1,keyword2,keyword3", ",", false);
int index = s.Search("... some text for searching...");
Console.WriteLine(index);
该控件不会搜寻所有存在的关键词，碰到第一个匹配的关键词，即返回该匹配的关键词在原文中的位置索引,没有找到则返回-1。
The most interesting feature I like in VC 2008 is the parallel build capability.
The /MP option can reduce the total time to compile the source files on the command line. The /MP option causes the compiler to create one or more copies of itself, each in a separate process. Then these copies simultaneously compile the source files. Consequently, the total time to build the source files can be significantly reduced.
I have encountered problem when attempting to compile VC projects created by QT 4.5.2,VC always rebuilds the whole project when I start to run or build the project, even though I didn’t make any modifications to the code.the project is always “out of date”.
Recently,I have rewritten the logging engine for LogMicroscope,using circular-buffer in log writing threads,and WriteFileGather in file writing thread to gathers up the data from these discrete buffers in memory and transfers them "in place" as a single operation.
