- The future is software writing its own software. Which is why I'm so in love with Pi: a coding agent that can extend itself :) lucumr.pocoo.org/2026/1/31/pi/
- Marp and slidev is nice, but agents are better at HTML and react and all that stuff. But then you need to rebuild the presenter view. So I build a reusable presenter view that works with (almost) any agent generated slide deck (incl. cloudflare funnel to remote control)
- Some small personal update: The who and why behind Earendil, the company I started with Colin Hanna. lucumr.pocoo.org/2026/1/27/ea...
- MiniJinja is now available with Go. It's all Codex and Opus built, but it passes the Rust tests and comes with docs and examples. github.com/mitsuhiko/mi...
- I'm sure we're all building beads now. I recorded a short demo of my shitty todos extension for Pi. It's modeled after Claude Code's task system with some neat UI integration. It's mostly for single-agent use, but it does support claiming of tasks. youtu.be/uPR7aAneg2U
- Weekend thoughts on Gas Town, Beads, slop AI browsers, and AI-generated PRs flooding overwhelmed maintainers. I don't think we're ready for our new powers we're wielding. lucumr.pocoo.org/2026/1/18/ag...
- Ukraine now has not a single power plant that was not hit by missiles, most of them not operational right now. Kiev currently is -13 °C. People are freezing for days, pipes are bursting. And we got so used to the news of the war, that it's not even a front page story any more.
- I don't think the situation in Ukraine has been this dire since the beginning of the war, and there is little to believe that this will improve. All the messaging around this issue right now is really, really bad.
- I summarized my thoughts of my MiniJinja porting experience if you're curious. There is also a video linked in there with a narrated coding session sped up. lucumr.pocoo.org/2026/1/14/mi...
- If a country bombs another country’s infrastructure back 50 years, and there is no sign of this ending, … at one point I wonder what the cost of surrender is. The news out of Ukraine are absolutely horrible.

- I feel like at this point nobody is surprised any more than an agent can port an entire code base, that took me months to write, to a new programming language, with all tests passing and adjusted APIs. We have come quite far already. bsky.app/profile/mits...
