Armstrong: Well, as an undergraduate some of the courses involved writing programs and I really enjoyed that. And I got to be very good at debugging. If all else failed, I would debug people's programs. The standard debugging was one beer. Then it would go up—a two-beer problem or a three-beer problem or something like that.

Seibel: That was in terms of how many beers they had to buy you when you debugged their program?

Armstrong: Yeah, when I fixed their program. I used to read programs and think, “Why are they writing it this way; this is very complicated,” and I'd just rewrite them to simplify them. It used to strike me as strange that people wrote complicated programs. I could see how to do things in a few lines and they'd written tens of lines and I'd sort of wonder why they didn't see the simple way. I got quite good at that.
