Chatted during a break in it with Marcelo Fiore a bit, the guy who gave the imaginary types talk. He gave me some pointers to some of the material behind Day's presheaf category construction from the BI semantics. Unfortunately, when I returned to my seat, my laptop was just dead. Plugged in, non-depleted battery, just refused to turn on. Suck, suck, suck.
lincoln3 recently ordered the appropriate cable to connect a laptop hard drives to a desktop, for his own reasons, though, so maybe once it comes in the mail I can get all my stuff off of it at least.
