As some feel that LtU is too math bound, there's only one solution for us underachievers - a Theoretical Computer Science Cheat Sheet.

(Most of it is vaguely familiar, as I've taken a lot of math courses over the years. Sadly though I'd need a much longer set of crib notes to jog my memory. Personally I think most CS based math is really simple, but it also is quite terse - much like many PLs.)
