If you're making a game, please, please, please remember to turn off the idle timer. The Force Unleashed, a big-budget game loosely modeled after the console game of the same name, is a moderately fun, very polished game, but the screen constantly dims during the game in cutscenes and other places where you're not touching the screen for a while.
I'm a programmer, author, and one of the founders of MartianCraft, a software development shop doing both contract and in-house software development.
My iPhone books (both written with Dave Mark) are published by Apress. My first book, Beginning iPhone Development (currently in its 6th edition) is the all-time best-selling book on learning to program the iPhone and iPad.
I also sculpt and take pictures when I need to engage the other side of my brain a little more.
