Sparring partner

One animated screen in a retro boxing-game style, hand-coded with Claude the same evening as the sparring session it shows. An original design, not any game's characters. October 22, 2026.

I never did drills. No reps, nothing like the real thing, just the real thing. Now I get round after round with AI. I throw an idea, it hits back with the hardest objection it can find, I answer, it scores it, we go again. My knuckles are bruised and the dummy is torn up. But I'm not fighting to win. I'm working toward clarity, and that's better than winning. We want the same thing, and both of us come out of it with a better idea than we went in with. The look is a nod to Mike Tyson's Punch-Out!! and its unforgettable opponents; Claudius is our own.

Idea: Mine, from an evening of arguing out Series 2 with Claude. The drawing is Claude's, from my description. · How I use AI

TL;DR

Matt thinks out loud here about technology, mostly how teams decide what to build, fix and protect.

The first series argues that security gets better fastest when the teams that each hold part of the answer share it earlier. Part 2 says most critical findings aren't: seven questions tell you which, and the answers live with other teams. Clay first, chisel later is about roughing out the whole thing before polishing the parts.

Every piece says how much AI helped, and the site is built in the open: a roadmap with a big picture (only Now is a promise), a changelog with a monthly review, and the product work itself, like Operatie Klompje, a postcard-sized product for one customer: his mom.

There's also an Arts and crafts wall, because not everything has to be serious. The discussion happens on LinkedIn.

The customer: my mom. Small, even in clogs. Giant courage, and giant worry. Most of what she knows about my work comes from the news.
