Thoughtful article about building older software with Nix: https://blinry.org/nix-time-travel/ It's striking how a project that does so much excellent work on build reproducibility still has some build errors in this scenario. Bitrot is scary.

All of Debian's patches for rustc: bugfixes, tweaks for the Debian environment, and even some reproducibility improvements. https://sources.debian.org/patches/rustc/1.40.0+dfsg1-5/ Many have a separate comment, which is really helpful.

@cstanhope runkit: https://runkit.com/ is a notebook-style UI that has stronger reproducibility guarantees AIUI. Jupyter is still exploring this space and I don't think there's a standard tool for enforcing reproducibility there.
