Ask HN: What's the oldest publicly-available repo with different versions?
What is the oldest collection of code out there, including different versions of the same project, where someone could access it and compare the changes between versions to get a sense of what changed?
By publicly-available, I mean where it is made available for anyone who requested it to somehow access it (e.g. from the internet, from a library).
With "repo," I'm not imagining it using version-control software per se, just that it could be compared and clearly show some kind of iteration of the same piece of code. Emacs source code goes quite far back, with extensive changelog between every 2 functions, if you don't fancy rifling through commit log itself: https://git.savannah.gnu.org/cgit/emacs.git/log/ Earliest commit is from 1985: https://git.savannah.gnu.org/cgit/emacs.git/commit/?h=emacs-... Log starting from 1985: https://git.savannah.gnu.org/cgit/emacs.git/log/?h=emacs-19.... The Python source - https://github.com/python/cpython/ - with full commit history back to 1990. The Unix source - https://github.com/dspinellis/unix-history-repo - with quite a number of releases dating back to 1970. Had no idea the Unix source was out there, very cool. Weird to see "53 years ago" on GitHub. Thanks!
