I second Aikido for a software developer martial art. It requires no physical force to apply techniques and control opponents (if you're a big burly guy your learning of Aikido will actually be hampered because the technique will work even if you don't do it properly), which is probably what you want if you're of average programmer build. If you like attacking, Aikido is not for you though. The movements are strictly defensive.
