I second Human Resources Machine. I just finished all the optimization challenges last weekend and it was extremely rewarding.
I'd say it's more about assembly language than general programming. You never (really) get enough power, with the 9 opcodes it gives you, to set up subroutines or functions. And many of the monstrosities that end up solving the problem would probably horrify Dijkstra in his grave. :)
