Big Tech ruined the cloud. So we’re renaming ours. ☁️ Home Assistant Cloud is now Home Assistant Link: an optional service from Nabu Casa for remote access, voice assistants, off-site backups & more, without cloud dependency. Meet Link 👇 home-assistant.io/blog/2026/…

Accessibility is not a luxury - it's essential business. Your .NET X-platform apps should honor A11Y. With 6.7, @UnoPlatform apps are text scaling aware. platform.uno/blog/uno-platfo… Change OS setting -> Apps update automatically. Honors text scaling. No more pinch-zoom/squinting. And better for screen readers across platforms.

Yes, it is sad indeed.
I spent 2.5 billion tokens, every limit I had and five days to make this. A GTA-style city, built with GPT-6 using only prompts. No code or 3D by hand. The whole point was to push it as far as it goes and wire in every API I had. The setup: Codex driving Unreal Engine 5, with Higgsfield, Tripo, Meshy, Seedance, Seed Audio and fal handling the buildings, characters, animations, materials and sound. 8 buildings taken from concept to game, 247 generated voice lines for residents and police, 10 radio tracks across 5 stations. Here's the honest part. Most of those tokens didn't go into building. They went into fixing. The model writes a mechanic, runs it, watches it break, and tries again for hours. Getting a character to open a car door and actually sit in the seat took an absurd number of passes. A carjacking needed two separate bodies to stay locked to the same grab. Half the work was animation that looked fine on its own and fell apart the moment it ran in the game. And almost all of that 2.5B is the same project history being re-read from cache on every request, not unique code. Procedural generation from prompts is genuinely fun to watch and wildly inefficient at the same time. The city started as glowing blocks with working driving, money and jobs underneath, and ended up somewhere I'd actually screenshot. Full breakdown: youtu.be/9lFE4T7iZKM

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.
