2988 questions of the kind that actually get asked — in interviews, in architecture review boards, and by the person who has to run the thing at 3 AM. Every answer states the trade-off rather than the slogan, and says when the obvious choice is the wrong one.

4 questions in Build Reproducibility.

  1. Build Reproducibility intermediate

    A build produced a different artefact from the same commit two weeks apart. Why does that matter, and what makes builds reproducible?

  2. Build Reproducibility intermediate

    A team proposes making every build hermetic - pinned toolchains and dependencies, no network access during the build, byte-identical output from the same commit. What does that buy and what does it cost?

  3. Build Reproducibility intermediate Multiple choice

    A team wants the same commit to produce a bit-identical container image on any machine, any day. Which single change contributes most?

  4. Build Reproducibility intermediate

    Your pipeline builds a container image from a tagged commit. Rebuilding the same tag two weeks later produces a different digest. The application behaves identically. Where does the difference come from, and which parts should you fix?
