 Watched something until around 10, then watched a football game. Fell asleep after the game was over, and got up at 7 to have breakfast. Started to work on markdown around 8:30. It doesn't rely on part 3, so I decide to implement it firstly. Basically completed all the features I want for desktop app, with the help of an open source project. Played piano for a short time after lunch, then worked on markdown again, and fixed some bugs. Slept around 7 hours today and completed 14 pomodoroes - one for learning and thirteen for work.
