- Sep 24, 2026 Incremental Correctness Under Source Mutation Every incremental build assumes the source tree holds still while it runs. What an edit arriving mid-build does to the graph, how tools detect it, and the snapshot technique that removes the assumption. developer tools
- Nov 4, 2025 Incremental Static Analysis: Dirty Sets and Cache Invalidation What can be reused when one file changes, how cache keys must cover dependencies and configuration, and why under-approximated invalidation produces confident wrong answers. developer tools
- Aug 29, 2025 Bit-Reproducible Builds and Nondeterministic Actions The specific places nondeterminism enters a compile and an archive, the flags that normalise them, and why a byte-identical rebuild is a prerequisite for trusting a shared cache. developer tools
- Feb 12, 2024 Content-Hash Caching and Early Cutoff How build tools key actions on cryptographic hashes of their inputs and command lines, and why comparing output digests lets a rebuild stop propagating before it reaches the link step. developer tools
- Jul 13, 2023 Action Cache Keys and Shared Build Caches The two-level structure of an action cache over a content-addressed store, what has to be in a key for cross-machine hits to be safe, and how eviction and poisoning failures present themselves. developer tools
