 Fell asleep soon after midnight, and got up at 7 to have breakfast. Worked in the morning to finish this round of refactoring, and fixed unit tests in the afternoon. Finally merged this branch, with 33k+/11k- lines, in around 5 weeks. Well, it's OK since no one else is working on this, I guess. Will review the entire project and add TODOs in the rest of this week. Played piano for a short time after lunch, and did a cycling exercise around 3. Slept around 6.5 hours and completed 12 pomodoreos today - one for learning, five for exercise, and six for work.
