好久没有学习Qt了，因为研究生开学，各种杂事，使得qt学习之路中断了一段时间，最近良心发现，要重拾qt，qt封装好了socket库，这使得我们我们调用socket库来创建网络应用相当快捷。比如用qt来下载一个文件，访问webserver都可以方便的使用。 » Read more: Qt学习之路——QHttp，QTcpSocket与QAbstractSocket

Open Source on Github: Your First Contribution (Repost)

August 22nd, 2013 by JasonLe's Tech 1,627 views

As a senior Computer Science student, I am constantly hearing about how great it is to contribute to open source projects on github. Many job listings list it as a qualification or a “plus”, and it is casually thrown around in conversation at all kinds of seminars and events at school. Sounds great, I should do that! The only problem is: I’m a huge noob! I’ve done well in my computer science classes at school, sure, and I’ve built some projects that my family and friends think are cool, yes, but surely I can’t contribute in any meaningful way to a project with real users, right?

error LNK1123: 转换到 COFF 期间失败

August 16th, 2013 by JasonLe's Tech 1,130 views

原来机器上安装了VS2010非常正常，安装VS2012后，出现提示
错误 13 error LNK1123: 转换到 COFF 期间失败: 文件无效或损坏，如图：

1345426628_5950

出现的具体原因是微软的链接文件的格式变了（让人无语的微软）
微软官方给出的具体解决方法是给VS2010打SP1补丁。
