A quick note: I will be out of town this week, giving a lecture in Berkeley. I realize I have not made provisions for blogging in this short—or our several others. Ordinarily, I’d say all blog posts are due on Tuesday, but that’s not enough lead time on my end. So: please ensure that you post this week on your blog before 1:30pm on Wednesday. If you are writing a retrospective blog post, please be sure to address some element of our classroom discussion in your post. Pingbacks, of course, as usual.
