Python检测生僻字的实现方法

解决思路首先想到的就是利用python的正则表达式来匹配非法字符，然后找出非法记录。然而理想总是丰满的，现实却是残酷的。在实现的过程中，才发现自己对于字符编码、以及python内部字符串表示的相关知识的缺乏。在这期间，踩过了不少坑，到最后虽然还有些模糊的地方，但总算有一个总体清晰的了解。在此记录下心得，避免以后在同一个地方跌倒。以下的测试环境是ArcGIS10.3自带的python2.7.8环境，不保证其他python环境也适用。python正则表达式py

qt webkit

arora是一个很不错的开源的浏览器,我说它不错并不见得它的性能很好,但它代码确实通俗易懂,在我的gcc4.7.2下编译只有一个warning,很多东西给出了不错的解决方案.我的downloadMgr还"借鉴"了它的代码随便吐槽一下qwebview之类的东东,居然下载还要程序员自己写qtwebkit

DWR框架入门

dwr框架(菜鸟入门)该文可以看做是作者的学习笔记，部分内容可以认为是个人理解，请读者注意辨别。DWR（DirectWebRemoting）是一个开源的类库,可以帮助开发人员开发包含AJAX技术的网站.它可以允许在浏览器里的代码使用运行在WEB服务器上的JAVA函数,就像它就在浏览器里一样.DWR采取了一个类似AJAX的新方法来动态生成基于JAVA类的JavaScript代码.这样WEB开发人员就可以在JavaScript里使用Java代码就像它们是浏览器
