Day of work at PIT-BAK google office. Wrestling with not entirely gratifying problems, but lots of fun seeing old friends; had lunch with several of them. Meeting with Frank and Carsten Schürmann and simrob in the afternoon trying to track down a bug in my thesis code. There were functions in there that I just had literally no memory of writing. Got some dinner at chipotle. Tried to work on sigbovik stuff and did not really succeed; went back to the apartment and crashed early.
