Homework 10 is now on the web site.
Also, I've committed the example files from last night's lecture to the example repository.
Last, if you are looking for a tool to make nicer class diagrams, you might want to check out UMLet. It can run either as a standalone application or as an Eclipse plug-in. I played with the standalone version for about 5 minutes and it seems ok. Kindly note that the handwritten class diagrams are fine, and I don't want you to waste a lot of time making them prettier. But if you feel the lack of a tool, here's one to check out. Thanks to Denis and Chander for the tip.
