More musings after some people got upset about the word clanker. https://lucumr.pocoo.org/2026/5/26/clankers/

Has been a while since I wrote about agentic engineering, so this time around some learnings of maintaining Pi as a junior maintainer to @badlogic@mastodon.gamedev.place https://lucumr.pocoo.org/2026/5/24/pi-oss/

“If someone 50 years ago planted a row of oaks or a chestnut tree on your plot of land, you have something that no amount of money or effort can replicate. The only way is to wait.” https://lucumr.pocoo.org/2026/3/20/some-things-just-take-time/

Motivated by how hard “equity” is to translate into German, I wrote about that missing word. https://lucumr.pocoo.org/2026/4/23/equity-for-europeans/

My kids and I built a little game with pi and codex over the weekend and it was a ton of fun. Some rough edges but with a bit of polishing I think getting agentic coding to be kids friendly is within reach. https://mitsuhiko.github.io/rope-man-game/

I know this website is not very receptive to coding agents still, but so much progress has been made in the last year. At this point they are such a pleasure to work with if you give them a bit of chance.

For working with kids we used vanilla pi, VoiceInk for text to speech and a small extension we built for drawing: https://github.com/mitsuhiko/pi-draw

Some weekend thoughts of recent mob behaviors. https://lucumr.pocoo.org/2026/6/6/communities-of-not/

Jarred rewrite Bun in Rust in a week with clankers. Say what you want about it, but that’s impressive. Also a reminder that this is happening while plenty of software engineers still dismiss the general utility of LLMs for programming. https://github.com/oven-sh/bun/pull/30412

I analyzed my coding sessions and on the text interactions some words stand out. And well, they also show up on Google Trends as spiking. Oh and so much slop in my Twitter mentions and on GitHub. Thus here are some updated thoughts on all of this. https://lucumr.pocoo.org/2026/5/4/content-for-contents-sake/

Mario and I talked about Pi and agentic engineering with Gergely Orosz.** **https://www.youtube.com/watch?v=n5f51gtuGHE

I think @antirez ds4.c is important! I wrote down my thoughts on why I built pi-ds4 and why we need to focus our local model efforts stronger than we do currently. https://lucumr.pocoo.org/2026/5/8/local-models/

After the AI Engineer conference, which was full of useful criticism, I remembered that the most confident takes on AI often came from the least exposure. Rejection is easy, trial and error is expensive. I wrote about it. https://lucumr.pocoo.org/2026/4/11/the-center-has-a-bias/

Trololol. I had the agent start using ua-parser-js, then it read the AGPL license after adding it and backed out immediately. This is hilarious.

This evening ends with some darkness. "Just for fun". https://dark.ronacher.eu/2026/3/14/the-others/

Since some asked: five months of Absurd in production. Durable execution on plain Postgres with tiny SDKs. The design held up fine, partitioning is still hard and some closing thoughts on the future of Open Source. https://lucumr.pocoo.org/2026/4/4/absurd-in-production/

@schwa@mastodon.social @btel@mastodon.social the FSF is very much aware that if the case goes against them, then it weakens the GPL significantly. So they have to really be certain before they go in front of a court to know it’s going to rule in their favor. That’s why I think we won’t see many cases that want to actually look to careful. The implications could be vast.
