How We Reduced Our CI Build Time by 70% — Shopify engineering on parallelizing tests, caching dependencies, and splitting their monorepo build. The section on test partitioning by historical duration is worth stealing.

The Go Memory Model — Re-read this every year. If you are using channels or atomics, this is the spec that tells you what is actually guaranteed.

Designing Data-Intensive Applications — Chapter 9 (free excerpt) — Kleppmann on consistency and consensus. Dense but essential. Good companion to the Jepsen posts.

SQLite Is Not a Toy Database — Makes the case for SQLite as a production database for read-heavy workloads. The benchmarks against PostgreSQL for single-node deployments are surprising.

Structured Logging in Go with slog — Practical walkthrough of the log/slog package introduced in Go 1.21. Good coverage of custom handlers and performance implications.

The Platform Engineering Maturity Model — Thoughtful framework for evaluating where your platform org sits. Useful for building the case for investment without overselling.

How Postgres Stores Rows — Deep dive into heap tuples, TOAST, and page layout. Understanding this makes VACUUM and bloat much less mysterious.

Writing Docs That People Actually Read — Stripe’s documentation lead on structure, examples-first writing, and why API reference is not enough. Changed how I think about README files.

Prometheus: The Documentary — History of Prometheus from the SoundCloud days to CNCF graduation. Good context for understanding why it works the way it does.

Error Handling in Rust: A Deep Dive — Even if you do not write Rust, the taxonomy of error types (recoverable vs. fatal, expected vs. unexpected) is universally applicable.
