- I've automated taking screenshots of my laptop screen + webcam and fuse them and organise by year/month/day/hour. This gives me a nice lookback at what I was doing on a particular day (assuming I was at my laptop, which I mostly am).
- I also send my GPS location each 30 minutes, again from my laptop, into a database for a nice visualisation where I was at some time.
- Automatically move files from my laptop into various folders which are stages of "stagnation" of the file, makes it easy to keep stuff clean.
