Igalia's post on self-hosting CI runners is a masterclass in build engineering. It shows dealing with weird API constraints, but still finding good designs.
I also learnt that some CI systems use OCR on Apple's installers to automate!
I see that *up has become an increasingly common name for toolchain installers: rustup, ghcup, even juliaup.
I think Rust was the first to use this terminology? I'm curious how similar the different *up tools are.
