Three-part series on making row updates fast in a column store: purpose-built engines (ReplacingMergeTree and friends), SQL-style UPDATEs, and benchmarks claiming 1,000× speedups over the old mutation path.
Context is the scarce resource in agent systems. Practical strategies for spending it well: compaction, structured note-taking, and when to reach for sub-agents.
The Devin team’s case against splitting work across agents: context lost between agents costs more than the parallelism buys. Read it together with their follow-up, Multi-Agents: What’s Actually Working, where they concede multi-agent setups work when writes stay single-threaded.
Still the best starting point on agent architecture. The workflows-versus-agents distinction and the five patterns — prompt chaining, routing, parallelization, orchestrator-worker, evaluator-optimizer — became the vocabulary everyone builds with.
