This is a simply program to track time spent on deep work (hacking, learning a language, research, etc). It is inspired by the following anecdote.
I remember Carmack talking about productivity measurement. While working he would play a CD, and if he was not being productive, he'd pause the CD player. This meant any time someone came into his office to ask him a question or he checked email he'd pause the CD player. He'd then measure his output for the day by how many times he played the CD (or something like that -- maybe it was how far he got down into his CD stack). I distinctly remember him saying "So if I get up to go to the bathroom, I pause the player".
- When you launch the program it starts a timer
- If you press space the timer pauses
- If you press space again the timer resumes
That's it! At least initially. Other planned features are:
- making it usable as a physical interface with a microcontroller
- multiple timer
- persistent state
