I couldn't recall how I got started in open-source, so I've used GitHub API to find the very first pubic commit. Turns out it was some JavaScript based game, committed all mostly in one go.<p>I made the script available for others to use:<p>https://gitspo.com/gajus/first-commits<p>Replace "gajus" with your GitHub username to find your first commit.
For anyone wondering, this is the relevant API <a href="https://developer.github.com/v3/search/#search-commits" rel="nofollow">https://developer.github.com/v3/search/#search-commits</a>.
