Writing
I write about building tools that let people and agents understand what they are working on—not just generate more code.
Essays
-
An end-to-end open-source platform for startup factories, assembled one missing building block at a time.
Notes
-
Long-term direction, conversational boundaries, and the limits of current models.
-
QuickBEAM 0.11 adds a JavaScript interpreter written in Elixir, so the BEAM can preempt, limit, and supervise it.
-
Reading existing code, understanding architecture, and checking for drift.
-
Models built to generate text are still bad at writing it, and continuing someone else’s fiction shows why.
-
Predictable habits, a plan the model keeps up to date, and prompts that keep getting shorter.
-
Where DuckDB fits alongside Postgres, and what QuackDB adds for Elixir.
-
How I handle pull requests when AI makes them cheap to open and expensive to review.
-
Design-to-code needs abstractions that map both ways, not generated backends nobody can maintain.
-
Vibe puts Elixir eval, stateful sessions, and supervised subagents at the center of a coding agent.
-
On imitation of competence, hiring rituals, and the cleanup cycle that follows.
-
JSX, structured JSON, and Bash are steps toward one declarative language, and models are learning behavior, not just text.
-
Models learn the most from acting in constrained environments, which makes feedback on their actions the valuable data.
-
QuickBEAM gives every JavaScript runtime a supervision tree, native BEAM terms, and no Node.js on the machine.

Figma shipped a silent patch to kill figma-use, so I recreated the core of it as OpenPencil in a weekend.
