My name is Yong Sun, a software engineer in Beijing, China. I love coding, and my favorite programming languages are C/C++, Python, and I have some programming experiences of Java, Objective-C/Cocoa, Ruby, Perl, and shell. I had been working on Linux/Unix about 10 years, though I’m working on Windows right now ;)

I’m one of the lead contributors of SunPinyin project, which is a statistical language model based Chinese input method. SunPinyin had been ported to various input method frameworks or operating systems. On developing SunPinyin, I studied some NLP knowledge, like n-gram modeling, VMM/HMM, MaxEnt and CRF etc, in which I really have interests.

My biggest strength, as well as my biggest weakness, is probably that I have too much interests, even in my personal life. I love taking photos, especially for my son, you could visit my album on flickr. I’m an Apple fans, that’s also the reason pushing me to port SunPinyin onto Mac OS :) And I like singing, most sports …

That’s me, welcome visiting :)
