The final stop on the lecture tour - watching light bulbs go off across a room of ravenous students

An 85-minute marathon lecture with the sharpest questions of the tour - and Emma Watson reading quietly nearby

A blockchain conference where I talked about robots, provenance, and the real utility of crypto

A room full of CS students, and the moment I told them they wouldn't have to write code anymore

From PostgreSQL backend to Liquid Glass UI — building a memory system you actually want to use

They started as 'just a CDN.' Now they're running 20% of the internet and offering what AWS charges $500/month for... at $10/month. Here's how Cloudflare became the most underrated infrastructure company in tech.

My dictation app had been quietly saving every recording next to its transcript for months. That is an accidentally-labeled voice corpus - exactly what a cloning model needs. So I cloned my own voice, 100% locally, from data I already owned.

How a stale /tmp/ directory silently wiped our Meta Pixel, served the wrong landing page to Windows users, and sent old OG cards to every social platform - all while we thought everything was fine.

I added API key rotation to a coding-agent harness to dodge free-tier rate limits. It didn't fire, then it fired at the wrong thing, then a 414-commit rebase deleted the file it lived in, and finally a 70,000-token error turned out to be a lie. Four failures, four disguises.

A routine DaisyDisk scan on my Mac Studio zeroed out two preference values, and I spent two days convinced Apple had killed Launchpad. They hadn't.

How I built a system that gives new coding agents memories from previous sessions - and what broke along the way

How three 50-inch TVs, a 4x4 grid obsession, and six rounds of maintainer feedback turned into 3,164 lines merged into a 30,000-star macOS window manager

How I turned 30 years of Grateful Dead concert recordings into a tool Claude can query - and the moment ChatGPT almost killed the whole project

I bought a mini PC with no monitor or keyboard. An hour later, it was a fully configured dev box - and I never touched it.
