Bobclass: Module systems are cool. I think I will continue to sit in on this.
Complexity theory: Rudich actually gave the lecture this time. The "sea of zeroes" argument.
Sleep: Uh, not so much. Somehow I continue with my habit of staying up late and waking up just before sunrise. This time waking up with lyrics flowing into my head in that weird coming-from-some-unknown-source feeling. Had to write them down and, having slept a couple of restless hours more, find a melody to fit them to.
