UC Berkeley's eighteen hour hackathon

I don't really get these things... why code all night when you could just as easily code all day without entirely throwing off your biorhythms and feeling like crap the next day? It seems to me that I'd be a lot more productive when I didn't feel like burying my forehead in the desk (see 9:15 AM).

Full disclosure: I was a judge. Trevor Blackwell (from yc/anybots) was too.

My career path might have taken some much more interesting twists when I was at Berkeley... I never discovered a hackathon happening then with punch-cards.
