 Went to sleep after dinner and woke up around 1. Got up to work on unit tests for a while and then did a cycling exercise around 4:30. Didn't work on unit tests in the morning and afternoon, but discussed a important feature with ChatGPT. Orginally I didn't plan to put it in the first version, but after several hours' discussion, I became more confident about that. Moreover, a feature the first version must have wil do similar things, which makes it easier to implement. Let me think more about this. The work is actually much more than I expected, but I can think more about tough stuff while doing some trivial work. Slept around 7 hours and completed 14 pomodoroes today - three for exercise and eleven for work.
