Václav Havel believed that truth was better than fear, freedom was worth fighting for, and Europe’s future belonged to everyone. He devoted his life to those convictions and helped change the course of history.
On what would have been his 90th birthday, I’m remembering my friend with gratitude for his courage, his love of our common humanity, and the work we did together to bring the Czech Republic into NATO and build a Europe no longer divided.
We also shared a love of music. So today, I’m playing a few notes in his honor. Happy birthday, my friend. The world could use more of your spirit.

Labyrinth Of Ur (2026) by Michal Ursiny for Commodore 64. A first-person 3D dungeon crawler written from scratch in C. Seven procedurally generated floors, one warrior, and Pazuzu waiting at the bottom. 🗡️

I resigned from Anthropic today. I spent the last three years doing pretraining research at both OpenAI and Anthropic. Neither company is acting responsibly. They are racing straight to self-improving superintelligence and gambling with our lives. More thoughts below.

Update on the #c64 Ultimate raycast game. Aspect ratio changed and canvas size increased to be more "gamey". Optimized the crap out of the raycaster and renderer, with a fixed 25Hz schedule now. Runs nice and smooth over 2 frames. Lots of other systemy stuff too.
