We just moved to a new site.

Hello All,

After being silent in posting for a long time, I have finally decided to resume my knowledge sharing practice. If you are interested in seeing the new posts, please go to the new site:

All the old posts have been ported to the new site. You are welcome to leave comments there and I will reply them. I am not going to reply to comments in this old site. Thanks.
