Went early to bed with a head full of stuff and woke twice through the night processing, processing! Result was to get up early and get some of it (conference paper beta) down in a coherent fashion. No Sudoku this morning, but a productive couple of hours in the cool, pre-dawn air with good coffee. It occurred to me that using Tumblr as a presentation tool and substitute for the Power Point might be an interesting experiment. One to try.
