Distributed systems lose, delay, and duplicate messages, and every fix for that has its own name. In this article, we build a distributed systems cheat sheet: 20 concepts from CAP to sagas, each with an example, its cost, and a link to the deep dive.

How Raft keeps several servers in agreement when any of them can crash: one leader, a majority vote, and a write that counts only after most servers store it. Explained step by step, with diagrams and no math.

Weekend Reading #96 covers AI controls across the SDLC, Meta’s confidential processing architecture for AI glasses, automated dependency analysis across Uber’s service mesh, and Elastic’s benchmark-driven system for safely optimizing Elasticsearch with coding agents.
