What are the possibilities of Agentic UI? What are typical patterns? How to avoid a chat with a text wall? I discussed these questions with @jaycooperbell.dev and @mhartington.io 👇

In the last 365 days Trellis.org has saved a mind blowing 8 years and 174 days of computation time with @nx.dev Cloud! 🤯 (just in CI!) That massive bar is our graphql-codegen target. Interestingly our computation savings were very very swingy from Aug 2025-Nov 2025 and then it drops down.

Google Play won't let me launch RoundForge (my free, combat-sports interval timer) until 12 testers run the beta for 14 days. I have 4. If you have an Android: send me your Google email, I'll add you + send an opt-in link. Install, keep it 2 weeks, done 🥊 Reposts help!

this is what open source is all about 🤍 > Looking back at this past year, it’s crazy how much has changed. From my very first small PR to becoming a maintainer in multiple projects. I’ve learned that communication is key in Open Source, and when people work together openly, incredible things happen

This ended up WAY longer than I was originally intending, turns out I had a lot to say on the topic. How an event-loop issue turned into a multi-week review of per-key revivers, schema-driven walkers, simdjson, V8 codegen, and custom pipeline for our Model Cache. tech.trellis.org/blog/2026-05...

I don't think tech at large understands how hard it is to be an open source maintainer right now. So many great folks are on the brink of burnout. Funding is drying out. We live in a security minefield. Companies think humans are disposable. If you're a maintainer, we care. You deserve the world.

Go out and see this movie on the biggest screen you can find. A fantastic adaptation of the book, set designs and visual effects are amazing, probably cause there's no green screens. I listened to a podcast with Lord and Miller (directors) after and the care that went in shows.
