 Slept for a short time after dinner, and got up at 10 to play FC as usual. Got some watermelon to eat around midnight, and drunk some rice.. wine? Didn't want to work then, had been confused about what to do next. Finally decided to focus on the "core" part currently, since there are a lot of trivial things to handle with UI. It should work conceptually, or in memory, then UI just provides a way to provide inputs and display outputs. It didn't have to be screen, keyboard or something like that. Played piano for a short time around 4. Went to sleep after breakfast and got up at noon to have lunch. Slept afterwards. Got up at 2 but still didn't want to work, so played Civilization instead. Slept again after dinner. Completed 1 pomodoro for learning today. Completed 56 pomodoroes last week, by the way.
