It's Donkey Day. Today in history.
I've taken a couple of days off work since Christine got home on Thursday from the hospital. Her total knee replacement surgery, performed a week ago today, though she still has to take pain meds. She left the house today for the first time since Thursday. I took her to Longmont Clinic to get her blood drawn (she's on warfarin, aka coumadin), then to Lowe's. Our neighbor Ray the Handyman started painting our house today - just in time, as we're expecting our first frost tonight, and possibly our first snow next weekend.
This afternoon I read Planet Migration through a Self-Gravitating Planetesimal Disk, a preprint by a group at the University of Rochester. The main interest of the paper is that they performed N-body simulations on a GPU. We've talked about doing this at SwRI. It sounds like Moore, Quillen, and Edgar have figured out how to do it, using a C development environment from NVIDIA called CUDA. There's no connection with Sarah Palin, so far as I know.
