Oban as a Durable AI Agent Runtime in Elixir
Most AI agent frameworks reinvent a job queue badly. Oban already is one: durable, idempotent, retry-aware. Run an agent loop that survives a deploy mid-run.
Amazon Let the AI Drive. It Hit a Tree.
Amazon mandated AI coding, let it touch infrastructure unwatched, and lost millions of orders. The fix was more humans per deploy.
AI Made Tokens Cheap. It's Making Hardware Costly.
Apple raised prices on Mac, iPad, and HomePod, blaming an AI-driven memory shortage. The cost of intelligence is falling; the hardware to run it isn't.
The AI Coding Agent Bugs I Catch Every Week
Eight failure patterns I see running AI coding agents daily: the confident wrong answers, the lost context, and the bugs they reliably ship.
Build an AI Agent Loop in 50 Lines of Elixir
Every AI agent framework runs the same loop: observe, decide, act, repeat. Here it is in 50 lines of Elixir with no framework, just a GenServer.
RAG in Phoenix: Hand-Rolled pgvector or Arcana?
The Postgres you already run does RAG fine without a vector database. The hand-rolled pgvector path in Phoenix, and when Arcana earns its place.
We're About to Stop Making Senior Engineers
The path to senior ran through the grunt work AI now does in one prompt. The knowing-vs-doing gap hits juniors first, and here's how to grow architects anyway.

Prompt Skills, Not Claude: Four Rules from Anthropic's Engineers
Most engineers prompt Claude one sentence at a time. Anthropic's own engineers prompt skills. Four rules from their recent talks, with the operator nuance the talks left out.
How I Prompt Claude as a Staff Engineer (50 Prompts I Actually Use)
Fifty prompts I use to ship production AI features, debug distributed systems, and write docs that don't rot. Code review, debugging, refactoring, system design, and PR-quality writing, with five full examples.
