GitHub Actions isn't a CI system. It's a runner, and the industry spent a decade mistaking one for the other. I spent years inside OpenStack's gate and five more building merge queues at Mergify. The difference is not academic.

alembic-git-revisions v10 is out! Second release with new contributors, pretty proud of this lib!

For fifteen years the smart move in developer tooling was to build on top of GitHub. That's over. Not because GitHub is dying. Because the primitives you were renting stopped being maintained.

Everyone assumes AI-written code breaks your build more often. We looked at 200K+ merges across 477 teams. It's the opposite. AI-assisted PRs break main HALF as often as human ones. 1.9% vs 4.4%. And no, it's not because they're smaller.

Mitchell Hashimoto says merge queues fall apart once AI agents flood your repo. I sell merge queues for a living. He's half right, and the dishonest move is pretending he isn't.
