AI Tutorials & Practice

What I learned building Vibrary with Claude Code — privacy-first activity tracking, realtime presence bugs, signed auto-updates, and a canvas engine that started as one HTML file.

Nine 2026 papers name the amortization-vs-staleness tension in action-chunk execution horizons; none writes the objective down. Derive it and the horizon stops being task-specific — with a floor cheap inference cannot cross and a wall wher…

We gave an LLM agent an MCP server that drives TIA Portal via Openness, then asked it for a conveyor-sorting state machine in SCL. It added the CPU, validated the simulator, wrote the FB, and shipped 14 test cases — and refused three thing…
