The Ultimate Hardcore Computer Geek Test

Hi! So I saw that OKCupid was holding a contest for the best geek test, and I thought, come on, Napoleon Dynamite?  That's not geeky, that's... dweeby.  So, I figured I'd contribute something geeky.

Warning: if you're not a serious computer geek, most of these questions will be completely unintelligible.  If you are a serious computer geek, some of these questions may still be unfamiliar.  If you think Napoleon Dynamite is a geek, go find a different test to take.
