There are 11 kinds of people. Those who understand binary, those who don't, and those who did and are really glad they haven't had anything to do with it for a long time.
(Forgive me. For most of the day I've been staring at hex microcode and trying to decypher various binary flags out of various hex words while trying to stumble my way through a moderately complex emulator package. Ugh.)
Apologies to the ThinkGeek t-shirt.
