- Nov 18, 2025 Drift Detection Without Reading Every Host: Sampling, Fingerprints, and Reconciliation How to find hosts whose state no longer matches their declaration, what a fingerprint over a state subtree can and cannot prove, and how detection frequency trades against read cost. devops
- May 5, 2024 Detecting Drift Between Reference Material and the Code It Describes Documentation goes stale one claim at a time. Separating checkable claims from judgement calls shows which kinds of drift a build can catch and which only review can. software engineering
