Can't agree more about the value of Discrete Math. Any programming worth his salt can wax about combinatorics and counting problems at a moment's notice. I'm thoroughly convinced I'd be a few years further along as a programmer had I learned discrete math at an early age.

But anyway, the Teaching Company offers a phenomenal course on Discrete Math, taught by none other than the "Math Magician" Arthur Benjamin (seriously, this guy is magic. He can do 5 digit squares in his head!). It's easily torrent-able / available through more traditional means.
