 Didn't sleep after dinner, played Civilization until midnight. Then started to work, on rewriting based on new ideas. Finally got a simple unit test to work at 4, I may add some unit tests to existing codes while developing new features at the same time. Played piano for a while after that. Didn't sleep immediately after breakfast, played Civilization instead. Fell asleep around 9:30, I guess. Didn't skip the lunch and slept in the afternoon, until dinner. Completed 10 pomodoroes today - one for learning and nine for work.
