Building and Thinking

One-off posts, plus a few ongoing series. Click a series to read only its posts.

  • Autonomous companiesOngoing efforts to build and grow several products sustainably. I want to be as effective as I can (10x+), solo.
  • Signals over vibesThe harnesses I build across products to work on signal instead of vibes, especially after sprints.
  • SocietyReading books and writing about business models that put respect for all life first. I'll turn my theories into action, eventually.
  • Product postsTechnical breakdowns of what I'm building. Usually post-sprint reflections.
  • Game devArt plus coding = short games I make on the side.
  • Better business questions

  1. The Purpose of the Better Business Questions Newsletter

    An introduction to the Better Business Questions newsletter — why business has power and responsibility, the Breakthrough Challenge framework, and a call for leaders to put people and planet alongside profit.

  2. From Full Disk Access to security-scoped bookmarks

    Stower stopped asking for broad Full Disk Access and redesigned around a narrower, testable access model — security-scoped bookmarks via the App Sandbox.

  3. The true nature of dark patterns

    Why dark patterns are really about disconnecting people from their own best interests — and what a company that genuinely respects human life would measure beyond revenue.

  4. Build your own harness

    Everyone's selling 20-agent orchestration templates. I'd rather grow my own harness out of real pain — and spend 90% of my time actually shipping.

  5. Why I moved Mortrel's encryption to the server

    I wanted the best design in terms of privacy and encryption, but because Mortrel is a consumer AI app, the worker has to decrypt to do RAG. I moved encryption and decryption to the server. Along the way, I did a bug hunt and went down a research rabbit hole.

  6. How I went from vibe coding to signal coding

    I did plan-driven development and had Codex review every plan and every diff. The codebase rotted anyway. Here's the harness I built for V2 — and why yours will look nothing like mine.

  7. A tale of two crons

    I tried to fix a one-line SQL bug. It turned into ~180 LOC deleted, a refactor, and three new design checks I now run on every plan.
