Machine learning: I ♥ decision trees. Oh, wait, no I don't. 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.
