RecRoom is closing! Very sad news for what was the greatest social VR platform. I’ve spent thousands of hours in there playing paintball and going round and round the incredible quests. https://blog.recroom.com/posts/schools-out-for-rec-room

Design docs considered harmful

Hot takes and cold truths on software, startups, and the lies we tell ourselves.

John Battelle's Search Blog Claude Says Non to Ads

Yesterday I wrote a short post on the impact that advertising would have on generative AI, a topic I’ve been thinking and writing about for the past three years. Seems the folks at Anthropic …

Excited to share Land of Assets, a new project I've created:

https://landofassets.com/

It's 3D asset infrastructure designed for developers working with glTF. Think GitHub for your 3D models: versioning, CDN delivery, and a typed SDK. Free for public assets. Looking for initial testers now. It is inspired by what we've previously built for large enterprises, bringing that technology for the open source world.

I propose we refer to these prompt-based libraries as “spells”

A Software Library with No Code

Do we still need libraries of 3rd party code when AI agents are this good?

One fun way to stretch AI models is to ask them questions about patents. Patents are wordy and well structured with minimal ambiguity - meat and potatoes for an LLM.

A great AI should be able to explain the invention with an infographic, build a virtual 3D model, and eventually perhaps start suggesting improvements. Spoiler: Opus 4.5 does OK, but plenty of room for improvement.

Claude Code is very good at helping with Home Assistant. Ticked off another entry on my personal TODO list in less than an hour and in a way that feels supportable going forward. https://github.com/rawnsley/CompCurve

I finally got around to trying Ai coding. I’ve made a Blender add-on, which is something I’ve done manually before, but not something I do every day. https://github.com/rawnsley/TexCut
