A keycounter, made to record one-dimensional data of computer usage for the purpose of visualization and analysis.
Use it with
minute is the original - it uses d3js to render minute output in-browser with some interactivity.
Sleep Chart calculates hours of sleep based on keystroke gaps. Depressing, right?
basically.js is a non-interactive but faster minute visualization based on node-canvas.
weekgram.js draws keystroke frequency per minute for a week, showing patterns in sleeping hours, etc.
How to Use it
Download the binary (see below), and run it. It'll record keystrokes at ~/Documents/minute/keystrokes.log in a
CSV document. In order for this to work, you need to grant hihowareyou Accessibility access under Security & Privacy of your System Preferences.
Remember: when you upgrade OSX, your accessibility permissions can get wonky. Remember to re-enable access after updating.
Developers
You can compile from source here, but you probably want to just download a pre-built binary to get this working.

What it Does, Technically
It fills in a log at ~/Documents/minute/keystrokes.log with
the number of keystrokes you make every minute.
All it does is count keystrokes. Unlike a keylogger, it doesn't steal your money, or do anything amusing that gains national attention. If you don't trust me, read the horribly constructed Objective-C yourself, or don't use it.
It requires the Accessibility API to enabled, or for you to trust the application.
