chess: I play 1. e4 as white, sicilian or benko's gambit as black. Willing to learn some other opening combinations in the future.
parenting: I am a husband and a father. My son was born in October 2012.
tex: I use LaTeX to prepare my teaching, create problem sets, etc (I am a math and physics teacher in zenius.net by the way). And I also use LaTeX to prepare meeting documents (I have a lot of meetings as the CEO of Zenius Education).
