I am currently a second year PhD student at City University of Hong Kong. And I am working on Covert Channel related projects (mainly for cross-VM covert channels in the cloud).

I am maintaining two blogs: 
As a Tech Recorder: blog.qiwen.name
As a Life Observer: life.qiwen.name

And some gadgets developed by me (several years ago..)
Sina Weibo Shortcut. Code Download in Chrome Store
Douban Music Parser. Code Download in Chrome Store
Sina Weibo Shell.    Code Demo
