**Other activities.**I am a big fan of the American Mathematical Monthly's Problem Section. Take a look at this page.

I also like to "waste" my time on earning reputation points (and learning new things) on math.stackexchange under alias Robert Z.

Every now and then I try the problems of Ponder This proposed by IBM Research.
