Sorry, I don't comment very often and not trolling. I had GitHub open to the repo on my phone and seeing that it had been taken down grabbed a screenshot of the page

The repo as I and many other people cloned it has the first commit ("first commit", not "initial commit") at Oct 12 23:20 Z, and the "done" commit at Oct 15 19:37 Z.
A likely explanation is that pixelmelt squashed both commits at or after they put up the blog post, but didn't force-push the rewritten history to github until it hit HN and blew up.
