Watched something until midnight, then turned to working as yesterday. Planned to do a cycling exercise at 4 but couldn't stop working at that time. Also worked in the moring, ans finished this round of rewriting, mostly. Had changed the foundamental data structure, to make it easier to write transforming functions for them, and as a result there were a lot to rewrite. I saw there would be no big changes on part 1, so designed a better data structure. Broke a lot of things, but unit tests made sure the core part worked as expected, although they needed to be updated slightly. Still need to fix something next week. Won't work but have a rest tomorrow. Slept in the afternoon and did the planned cycling exercise in the evening. Slept around 5.5 hours, as yesterday, and completed 21 pomodoroes today - five for exercise and sixteen for work.
