Finished [sic] rewriting the introduction to the first-year Python book we've been working on.
Lost a game of chess (came out on the short end of a messy trade).
I'm now heading out to the pub with students and colleagues. Life isn't bad.
Later: about forty people showed up at the pub. Madeleine was, of course, the hit of the party ;-) Thanks to Serguei for the photo below.
