2026. Ein Terminbuchungsportal erlaubt standardmäßig nur die großen Mailanbieter. Eigene Domain? Ticket aufmachen, warten, bis ein Techniker sie von Hand freischaltet. Kein MX-Check, kein Double-Opt-In. Menschliche Freigabe.

The new Sternbrücke is on the move: 108 m long, 4,500 tonnes, rolled through Altona to replace a bridge from 1926. There’s a livestream. #hamburg www.eisenbahnbruecken-ehm.de/sternbruecke...

A fun experiment I'm pursuing with Codex, building a simple browser rendering engine within a browser via Rust / WASM - Latest and most sophisticated take so far: play a video file with sound and do all the work in wasm. Codex runs for more than 16 hours already, and it's getting there

Shipped a full music video end-to-end with AI: song from Suno, scenes from Seedance, lip-sync via another model, orchestrated from Claude Code. Wild what a bit of AI plumbing gets you these days. Heres the teaser

Hamburg rush hour.
Backlit silhouettes of a coxed four rowing across the Alster in Hamburg on a bright morning, with a goose family — two adults and three goslings — paddling in the foreground. The water sparkles with sun, and a tree-lined shoreline sits in the distance.​​​​​​​​​​​​​​​​

A PM threw some design mockups over the fence. Instead of manually iterating, I set up Claude Teams (mockup-artist, ux-designer) with access to the Nanobanana CLI to riff on them.

These ice blocks near Hamburg in Geesthacht made it to major news in Germany – so it was quite crowded even at -5°C and strong wind 🧊❄️

Just used Beans for Claude Code for a smallish refactoring - and I quite like it. Simple, markdown files, nice TUI to see what's going on and potentially even edit stuff. Claude Code and the TUI on split screen.
