Distinctly less crummy day. Had a good project meeting. Talked about this type system for differential privacy a bit, and Benjamin's questions cleared up a few things that were fuzzy about it to me before. Discovered I did not lose one of my gloves. Went to a talk by a consummate engineer dude from Berkeley about power monitoring in buildings, and electrical power consumption in general, and how awful (desktop) computers tend to be at idle power consumption compared to, say, printers, which are actually very good about it.
