some words about this blog.

I have been thinking of opening a blog to enable me to write my understanding of things. And now this is idea is finally put into effect.

This blog is planned to be a technical one. I will wrote more posts about interesting technical problems I find than about going to karaoke stuff. After I recently decided to transfer from PH.D. program to Master program, I am beginning a long period of studying and reviewing of all the core knowledge in computer science, including data structures, algorithms, operating systems, and also more advanced subject like data mining and machine learning.  I am looking for a summer software developer intern this year, and will be looking for full time position starting from the end of this year to next summer.

Some of the posts will be written in Chinese most of which will be non-technical.
