If you found this blog by using Google, you probably noticed that everything sort of stopped in September. This was because the course was actually meeting and the blog was less necessary. (I did delete some very specific end-of-semester information just now too.) Up until this morning, the class had very few people signed up, and it wasn't at all clear that I would be teaching it. That's all changed now, and over the next couple of days, I'll put the blog into shape for the Spring semester.
