Actually had a great object lesson in figuring out where my code could be better. My development machine went belly up on me a week ago, and because my office has been pretty ravaged by the flu, it took about a week to get a new one up and running.

Coming back to it afterward, there were quite a few places where I found I had to work through some code in my head. Needless to say, I've been spending some time getting those nasty patches in better shape.
