Articles and notes on modern software production lines: DevOps, SRE, AI engineering, and the platforms beneath them.https://bluecloud.dev/en-UShttps://bluecloud.dev/notes/andon-cord-is-a-reward-structure/https://bluecloud.dev/notes/andon-cord-is-a-reward-structure/The interesting thing about an andon cord is not the cord. Pulling a cord is trivial. The interesting thing is the answer to the question: what happens to the worker who pulls it?Sun, 24 May 2026 14:00:00 GMTdevopslineagefeedback-loopshttps://bluecloud.dev/notes/evals-are-tests/https://bluecloud.dev/notes/evals-are-tests/The reluctance to call AI evaluation harnesses tests costs more than the renaming saves. Tests get reviewed, run in CI, and have an owner. Evals deserve the same treatment.Sun, 24 May 2026 13:30:00 GMTai-engineeringqualityfeedback-loopshttps://bluecloud.dev/notes/trunk-based-development-is-not-about-the-trunk/https://bluecloud.dev/notes/trunk-based-development-is-not-about-the-trunk/The criticism of long-lived branches is usually framed as a criticism of the branch. The actual problem is batch size. The trunk is just where batch size becomes visible.Sun, 24 May 2026 13:00:00 GMTdevopsantipatternsdev-experiencehttps://bluecloud.dev/articles/fail-fast-consolidate-faster/https://bluecloud.dev/articles/fail-fast-consolidate-faster/Modern organizations have become very good at trying new technology and much less disciplined at absorbing it. In the AI era, the risk is not experimentation itself, but experimentation without consolidation.Sun, 24 May 2026 00:00:00 GMTai-engineeringpatternsdev-experiencefeedback-loopshttps://bluecloud.dev/articles/platforms-are-paved-roads-not-walled-gardens/https://bluecloud.dev/articles/platforms-are-paved-roads-not-walled-gardens/Internal platforms succeed when they pave the road most teams want to walk and fail when they wall off every other path. A platform that cannot be bypassed is a platform nobody trusts. The work is making the default obvious and keeping the exit honest.Sat, 23 May 2026 21:30:00 GMTplatformsprinciplespatternsdev-experiencehttps://bluecloud.dev/articles/ai-engineering-needs-audit-not-faith/https://bluecloud.dev/articles/ai-engineering-needs-audit-not-faith/Useful AI in engineering keeps the same property useful tests have: a human can read what happened, where it went wrong, and decide what to do next. The argument is not that AI is dangerous. It is that anything shipping to production has to be inspectable when it fails.Sat, 23 May 2026 20:30:00 GMTai-engineeringprinciplesqualityhttps://bluecloud.dev/articles/slos-are-a-reliability-question-not-a-number/https://bluecloud.dev/articles/slos-are-a-reliability-question-not-a-number/A service-level objective is not a number on a dashboard. It is an answer to the question 'how reliable is reliable enough — and to whom?' Without that framing, the math becomes reliability theater.Sat, 23 May 2026 19:30:00 GMTsreprinciplesfeedback-loopshttps://bluecloud.dev/articles/devops-is-a-production-line/https://bluecloud.dev/articles/devops-is-a-production-line/DevOps is not a tooling movement. It is the cultural import of a hundred years of production engineering into software — and reading it that way makes the discipline coherent again.Sat, 23 May 2026 00:00:00 GMTdevopslineageprinciplesquality
