Wow, this is surprising.

I’m happy for the founders, they’re great folks. I contributed to CirrusCI a bit in the past and it was a great experience. I even advocated for Cirrus in a couple of my last $DAYJOBs (with varied success). Congrats Fedor!

I’m very sad they’re shutting down, though. IMHO CirrusCI was very close to a perfect CI system (I wrote a blogpost about it [0]). I’ll now have to find something to replace it with in my personal projects. I guess I’ll run their cirrus-cli in GitHub Actions for a while. But GitHub Actions is really poor. I heard some good things about Buildkite.

A pity. Cirrus has been providing quite decent CI facilities, for free. One of the advantages (among many) compared to GitHub Actions is the large variety of runner images, e.g., Debian, Fedora, Alpine, FreeBSD, ...

I don't think people have been keeping track but OpenAI has been hiring a murderer's row of developers for their Codex team.

Tart is an amazing tool, and I have been very grateful for it. There's almost no other way I've found to stand up ephemeral CI/CD macOS VMs for self-hosted Git forge solutions. I really hope this doesn't mean that Tart will eventually die the death of unmaintained projects (e.g. Realm post-Mongo-acquisition.)

The level of aqui-hires is getting interesting - at this point, it appears that if one wants one's career to progress, you need to start some kind of tiny startup like Astral or Bun and hope to be notable enough you can get acquired by someone like OpenAI or Anthropic.

It certainly makes the idea of a career progression / promotion more challenging than it used to be, but perhaps it also opens up some new opportunities. It becomes far more "high stakes" since you have to take the risk of starting and running a startup that ultimately fails if it does not get acqui-hired.

Cirrus gave a ton of support for years to open source projects. I congratulate them on cashing out. Running a business like Cirrus did is always a hard road and I will never fault folks who gave time and resources on their platform away for taking the money.

I wish Fedor and everyone at Cirrus the best of luck and OpenAI and thank them immensely for the years of free CI they gave to us in the Pony programming language despite it not having any marketing value to them.

As a tart cli user, I'd love to know more about their "more open" licensing of that particular project that they call out that will follow the merger.

That said, I find their aqui-hire by OpenAI disappointing for a number of (mostly personal) reasons. However, I wish them the best regardless.

Why are they acquiring seemingly random things, they acquired Astral and now this

That is a bit sudden, it would be great if it was possible to get an extra month for migration.
