something changes.
An email when I publish new writing or the setup on /how-i-build changes. Sent by me, not a platform, a few times a month at most.
Recent updates
- Watch me walk through how I build
I spent eighty minutes on The Bellmann Show sharing my screen: how an idea becomes a merged pull request without me writing it, how a customer call turns into fixes, and the bottlenecks I keep hitting. How I build now links to it, with the best chapters.
- Compute is down. The next wall is me.
My fleet now watches its own memory and CPU, rents a Google Cloud machine when all three of my computers are full, and deletes it when the job is done: 30 machines in the first week for $2.05. That broke the compute wall, and the one behind it is human attention, so How I build now has a ninth wall and my guess at what breaks it: letting agents make more of the routine decisions themselves.
- The site soundtrack is on Spotify and Apple Music
The music in the player at the bottom left of the site is now out as an album, Above the Fog, plus a single, Signal From the Basement, on Spotify and Apple Music. The player links to whichever one the current track is on.
- Open source, starting with MetaBro
The homepage now has an Open source section with what I have published on GitHub. The newest is MetaBro, a Claude Code plugin that tells you, in a surfer-bro voice, when you are fixing the output instead of the harness that produced it.
- How I build: five practices, four skills
New on How I build: why a self-repairing job should never wait for me, why the agent decides and a script does the work, and how a week-long job hands itself to a fresh session. Four new skills too, including six sub-agents that each own one question before I make a bet.
- Every skill I wrote, in one map
Execution is mostly covered now; the ideas are what matter. So How I build now maps all 157 skills, 48 commands and 21 hooks I have written, by area and group, as a 3D brain or a tree. Open any skill to see what it does and copy it as a prompt to build your own. There is also a new section of practices: the habits around the skills, filed under the same areas.
- Start here: Claude Code for beginners
Everything I tell people who ask how to get started with Claude Code, in one place: what you need, a twenty-minute install, how to talk to it, a first project and the habits for your first month. If someone keeps asking you, send them this.
- How I build: Orca, cloud burst, my own mail client
I moved from cmux to Orca and opened about 110 task worktrees in five days, and when my three machines are full the fleet now rents a cloud machine for the job. The October timeline and the compute wall have the new numbers, and the ideal setup now leads with the 3D plan. I also started building my own mail client in Swift, shaped around how I handle email.
- The Takeoff has its own site
The Takeoff, my documentary series following the AI takeoff one year at a time from 2026 to 2046, now lives at thetakeoffseries.com, with every episode, a companion guide for each, and a new year every Tuesday.
- How I build: a year of building with AI agents
A measured account of a year building SKU.io with Claude Code: the eight bottlenecks along the way, the setup that removed each one, and the numbers behind it, all taken from my own session logs.
- mizzi.com, rebuilt
The 2003 site is retired after 23 years. The new one covers what I work on now, and the original is still up at /2003.
