Earned my B.S. in Computer Science at the University of California Santa Cruz (UCSC)

Programmer, amateur mathematician, gamer.

I'm mainly interested in the theoretical side of computer science, but pretty much anything relating to programming/engineering is interesting to me.
Awards, Diplomas etc (how to win them?):

Currently nothing here :(
