Summary

I do $random_contributions around the Rust project, based on $vibes². My style of contribution is probably most accurately described as "efforts towards enabling other contributors", since I mostly work on the test infrastructure (compiletest and friends), the build system (bootstrap), and the rust-lang/rust CI. I guess I'm also involved in a lot of firefighting, from CI problems to compiler beta regressions. And your usual maintenance activities, like triaging, reviewing release notes, prioritizing regressions, updating contribution docs, etc.

During this year I became employed full-time, and so I contribute during my free time, which means I have less bandwidth than I used to. My contributions mostly then manifests in helping with review bandwidth around the compiler, bootstrap and infra parts of the Rust project, among other things.

If I had to summarize, my main contributions would be:

• Getting rid of the Makefile-based tests/run-make test infra, in favor of plain Rust test programs.
• rust-lang/rust CI firefighting. E.g. (1) (2) (3) (4), etc.
• Helped with the bootstrap stage 0 sequence redesign efforts and follow-up fixes to get it over the line.
• A bunch of compiletest (test infra) related fixes/cleanups.

Thoughts?

• There are way more stuff I would like to work on than I have time for, and said list of things keep on growing. I keep getting distracted while being already distracted³.
• Current full-time $job + free-time OSS contribution model probably works best for me, even though I am very glad to see initiatives like the Rust Foundation Maintainers Fund to better support other maintainers. Reason is simple: I would like my hobby to remain my hobby, and turning it into a job risks taking away some of the fun.
• It's fun to interact with other maintainers from all around the world :)
