Ask HN: What's the best, but relatively unknown use of Git you've seen?

The use of git to track timeseries data is pretty neat. I have one private git repo which a machine will periodically update with it's public IP.

Here is a group that tracks public data sources in git: https://github.com/datasets

I haven't seen this, maybe it was done before but at least I haven't seen it widespread but I'd love to: tutorials.

think that each step is either a branch or a commit. whenever you're done, just switch to the next branch. even if you're git-illiterate, you could have a next.sh for pointing to the next step in the tutorial. same logic for check.sh to verify completion. you have built-in diff for changes between steps, you could work in whatever IDE you like, and it may not be limited to just code, too.

It's the data layer of https://www.passwordstore.org/.
