The first somewhat social platform that I’ve used was LiveJournal; I used it around 2004-2010. Back then, we had posts and comments, but one of the notable features of the platform was the uni-directional friend relationships. The number of people who befriended you was somewhat of a status symbol, with a special term “тысячник” (a person with 1000+ reverse friend connections) used to denote Popular People. That said, my recollection is that people mostly wrote what was fun or i...| zeux.io
When working with mesh shaders, the geometry needs to be split into meshlets: small geometry chunks where each meshlet has a set of vertices and triangle indices that refer to the vertices inside each meshlet. Mesh shader then has to transform all vertices and emit all transformed vertices and triangles through the shader API to the rasterizer. When viewed through the lens of traditional vertex reuse cache, mesh shaders seemingly make the reuse explicit so you would think that vertex/triangle...| zeux.io
In the process of working on calm, a minimal from-scratch fast CUDA implementation of transformer-based language model inference, a critical consideration was establishing the speed of light for the inference process, and measuring the progress relative to that speed of light. In this post we’ll cover this theoretical limit and its implications.| zeux.io
I joined Roblox in August 2012; eleven years and 4000 commits later, it’s time to say goodbye. Today was my last day.| zeux.io
Machine learning is taking the world by storm. There’s amazing progress in many areas that were either considered intractable or had not reached a satisfying solution despite decades of research. A lot of results in machine learning are obtained using neural networks, but that’s just one class of algorithms. Today we’ll look at one key algorithm from meshoptimizer that was improved by getting the machine to find the best answer instead of me, the human1. A necessary disclaimer: I’m no...| zeux.io
