My list: sets, graph theory, combinatorics, linear algebra.

Differential equations and calculus don't help much other than conceptually; for example, if you're writing a computer simulation that models partial differential equations, then you're not going to solve it the way they teach in general diff eq as an undergrad.

Finite automata and cellular automata are also very useful to know.
