The Red Strings Club OST and the calmer Deus Ex soundtracks are really excellent for programming too. The mood I attribute it to is "competent thoughtfulness with light pressure toward action". I know that is a silly way to put it, but that is music for you.

Similarly good are parts of the Fallout OSTs and Minecraft OST. I have listend to a bunch of game and movie OSTs for films and games I haven't even watched, it's a great source of programming backing tracks.
