@mort "Possibly more evidence that sorting the heating out really could have some useful impact on energy consumption". My Lab office is so cold I havent worked out of there for four years, so I guess fixing that would increase energy consumption?

if anyone's still in the unlikely situation of using opam 2.0.x rather than a newer version in OCaml land, please chime in here https://discuss.ocaml.org/t/proposal-make-the-minimum-tested-opam-2-1-and-higher/17736
Proposal: make the minimum tested opam 2.1 and higher
Much as we did a while back with raising the minimum version of OCaml tested to 4.08, it’s now time to raise the minimum version of opam that we test in the CI matrix. opam 2.0.0 was released in 2018, and ever since then the Docker images have built every version, with the default being the minimum version (2.0.x) all the way through to 2.5.x. I now propose that we raise the minimum tested version of opam to 2.1.x. Looking in repology/opam, the only notable distro still shipping opam 2.0 is Ub...

Kind of surreal seeing Claude Code Cowork use the same Linux-as-a-library-VM trick on macOS we first shipped in Docker for Desktop a decade ago (https://anil.recoil.org/papers/2025-docker-icfp.pdf). Looks like the architecture of embedding Linux on any non-Linux desktop is now everywhere!

macOS having memory tagging in mmap(2) caught my attention the blog post on fixing ghostty's memory leaks. Looks like it's used heavily in macOS already, but I can't find a Linux arm64 equivalent anywhere

I've built "unpac" today to make it possible to vendor _all_ (OCaml or other) package dependencies in a single git repo, using 100s of orphan branches and git worktrees. This makes agentic programming way more reliable as the agent has access to all the OCaml/OxCaml code.
