Although we may start discussing migration tomorrow, I'm unlikely to have revised notes posted before lecture. (You can look at the old ones by following the link from the "Notes" page, rather than the non-existent link from the lecture detail page.) I apologize for not having them ready, but I'm going to be spending the rest of my afternoon and evening grading papers from Project #1. I want to hand them back and to talk a little about the results tomorrow.
