LLMs are a lot of fun to play with, but I wish they had a mini-map like code editors to serve as a table of contents for your input prompts to quickly navigate long chats. Or, a threaded reply layout like Slack for when things invariably go off the rails.

The great thing about an L-shaped desk is that it is really good at relicing your guitar headstock and body. Because no matter how you sit you end up bumping either one.

Looks like the Threads app landing page (https://www.threads.net) is based on Three.js and using a single instance draw call for about 6000 spheres, at about 11 million triangles. WebGL is pretty neat. #gamedev #rendering

While still early it’s a great step forward for compute based rendering, with the potential for reducing complex compute shader chains and serial round-trips to the CPU. #gamedev #rendering
