 Again, started to work after midnight and became sleepy after 4. Skipped the breakfast and got up at noon to have lunch. Played piano for a while after that. Tried to update my https certificates but encountered some problems, included but not limited to docker hub problem, next cloud upgrade problem (always a pain)... didn't solve all of them and turned to working. Also worked for a while after dinner. Completed 11 pomodoroes today - one for learning, three for research and seven for work.
