Ok, I have the blog running now. I sent out an email with this link already, but here it is posted on the blog as well. The second lecture is here, on YouTube. There is also a handout (PDF) that goes along with it (just a printout of the slides).

Particularly in these cases where there was no reading assigned, the expectation is that you will have watched these before class. I’ll assume it as background in the class discussions, and things that are covered there will be on the exams and homework. I might still give out readings sometimes, and there probably won’t be a video to watch before every single class, but they are to be considered required.
