Yep. I worked on the engine of a PS3/360 AAA game long ago. We spent a long of time building a pipeline for precomputed lighting. But, in the end the game was 95% fully dynamically lit. For the artists, being able to wiggle lights arou

Keet is based on https://holepunch.to/ which I came here to say “Why don’t I ever hear about this around here?” Holepunch is about open source tech for P2P apps without servers.

A fun fact I learned recently, after years of casually skimming color science, is that our eyes cannot focus the entire visual spectrum at once. That’s why our cone response to the spectrum looks like https://en.m.wikipedia.org&#

Converting waste to fuel is great. Meanwhile, I’m pretty excited about this project to make it cheap and easy to convert solar power to liquid fuel. Starting with carbon-neutral natural gas. https://youtu.be/cRg1ZVwttNU?si=J

So... I just did a little reading. And, I get the impression that if you want to do what I was suggesting, you'd have to physically walk up and talk to Brett Victor about it. https://dynamicland.org/2024/Is_Realtal

Their thesis is that you cannot get the training data for a robot in the home from a lab or a simulation. You have to actually put a robot in real homes with all their messy details. But, how to do that safely? First they build a robot wit

It would probably involve a small physical adjustment to the device. Whether or nor Meta provides that option is a good question. VR and AR devices so far always use a fixed focal plane for everything. Usually around 1 meter. So, if you are

I’m not sure why compilers generate slow code for SIMD intrinsics when optimizations are disabled. But, it is observable that they do. Aras and pretty much all gamedevs are concerned about this because they use SIMD in critical loops and de

You would appreciate https://aras-p.info/blog/2024/09/14/Vector-math-library-code... TLDR: SIMD intrinsics are great. But, their performance in debug builds is surprisingly bad.

I'm pretty far from an expert. But, at it's core ML is a bunch of matrix multiplications glued together with non-linear functions. So, quantization leads to less accuracy in the matrices of weights. Not, changes in hashes where 1

"Quantized" models try to approximate the full model using less bits. "Distilled" models are other models (Llama, Qwen) that have been put through an additional training round using DeepSeek as a teacher.

Yeah. People looking for “Smaller DeepSeek” are looking for the quantized models, which are still quite large. https://unsloth.ai/blog/deepseekr1-dynamic

If you are a hobbyist, academic or garage startup, absolutely use ROS. It will take you from nothing to something faster than anything. But, the moment you ship your first product, open your task tracker and add “Epic: Migrate off of ROS to
