 Didn't go to sleep after dinner as usual. Headed to the living room to play FC until 11, then made some hot dry noodles to eat. Started to work afterwards, on some simple refactoring. Stopped working around 3 and then played FC and watched anime. Slept before and after breakfast, and got up at noon to have lunch and play piano as usual. Checked the code base to see if there were some simple refactoring I could do. This part was mostly done. Compared to the prototype I had written by the end of last November, this version supports less data type, but with better code quality, I could publish it if this is all I want to do. Oh, UI is still rough. And better with some unit tests. The core part is written in plain typescript, depend on nothing more than effect-ts's Option, Either, Effect (basically ReaderTaskEither) and their related functions. So writing some unit tests should be easy. Next week, I would start to develop some completely new features, compared to the last prototype, and was unthinkable at that time. Completed 9 pomodoroes today - one for learning and eight for work.
