Long time no update

It is a long time since my last update to my blog.
Why? Basically, i am super busy and there is nothing much worthy to update.
Recently, I am studying a course "Introduction to Algorithms" from MIT network.
Wow, it is so impressive that I download the eBook and Video of the courses.
Doing the homework, listening to the prof. and thinking by myself are the best life in campus, I guess.
And it is so great to know that I sitll can involved in class after one year leaving the campus.

Nice day, gentelmen and ladies.
