 Played FC until midnight, then got nothing to do. Not very interested in the game, so played piano for a while. Started to watch football games around 4. Planned to do a cycling exercise in the morning, but I became sleepy. I will do nothing in the rest of today, so write journal now. And summarize my project. Part 1 had already been done, incluing UI for desktop and mobile apps. Tabs, sidebar, menus, pages, links and buttons are mostly in their position and function well, though they don't look very great. And also need unit tests to make sure they work as expected perfectly. Some UI job are scheduled for this week, but I may not work any more, to alleviate the stress from the two weeks completing more than 80 pomodoroes. Anyway, I will start to work on part 3 next week. It's clearly more difficult than part 1, but since a lot of codes can be reused, it's reasonable to expect part 3 could be done before April. At least I hope so. Then I will work on some advanced features: query, constraints, type cast and markdown. Sounds not very exciting? I got some great ideas about them. Of course, they are just ideas for now. Also need to develop core library and local api. Certainly it will not be able to connect to any devices for the first version...I admit it's misleading to say it's "all about signals", actually I hope, even without the ability to connect to devices and communicate with them, it could also be a great way to record something in a strutural way. And maybe I should integrate a chart library. I could also work on preparation for release at this phrase. These work are not so hard as part 3, but there are so many that they're likely to take longer.
