Rasterizer: A GPU-accelerated 2D vector graphics engine in ~4k LOC

news.ycombinator.com Unknown 2025-10-04 10:56:30

Rasterizer Inspired by my love of Adobe Flash, I started to work on a GPU-accelerated 2D vector graphics engine for the original iPhone, and then the Mac. Three iterations, and many years later, I have finally released Rasterizer . It is up to 60x faster than the CPU, making it ideal for vector animated UI (press the T key in the demo app to see an example). The 10-year gestation was the result of endlessly iterating over the core problem of efficiently turning vector paths into reference-qual

Neuralink’s Bid to Trademark ‘Telepathy’ and ‘Telekinesis’ Faces Legal Issues

The United States Patent and Trademark Office has rejected Neuralink’s attempt to trademark the product names Telepathy and Telekinesis, citing pending applications by another person for the same trademarks. Neuralink, the brain implant company co-founded by Elon Musk, filed to trademark the names in March. But in letters sent to Neuralink in August, the trademark office is refusing to allow the applications to move forward. It says Wesley Berry, a computer scientist and co-founder of tech star

Toronto’s network of pedestrian tunnels

news.ycombinator.com Samuel Hughes 2025-10-13 17:44:14

Toronto has one of the world’s great commercial downtowns. Two metro lines, eight suburban heavy railways, an extensive bus system, a highway, and North America’s greatest surviving tram network all converge on a tiny area by the shores of Lake Ontario. Hundreds of thousands of commuters pour into the downtown every day, filling the great towers that line its nineteenth-century streets. As with many downtowns, this causes congestion. Streets and pavements are thronged at peak times. Bicycles, p

Compositional Datalog on SQL: Relational Algebra of the Environment

news.ycombinator.com Hey There Buddo 2025-10-14 03:09:50

I spent some time before making Datalogs that translated into SQL. https://www.philipzucker.com/tiny-sqlite-datalog/ There are advantages. SQL engines are very well engineered and commonly available. SQLite and DuckDB are a pretty great one-two punch. A new twist on how to do this occurred to me that seems very clean compared to my previous methods. Basically, the relational algebra style of SQL actually meshes with manipulating the Datalog body environments (sets of named variables bindings)

An interactive guide to SVG paths

news.ycombinator.com Josh W. Comeau 2025-10-28 11:19:05

Introduction The SVG <path> element is notoriously tricky. When I first encountered it, I found it totally inscrutable. Its syntax isn’t quite as bad as Regex, but it has the same sort of “what on earth?” vibes. At the same time, <path> elements are also incredibly useful. They’re the only way to create curved shapes in SVG, beyond full ellipses. And once you get the hang of it, they’re actually quite a lot of fun to use!

The Core of Rust

NOTE: this is not a rust tutorial. Every year it was an incredible challenge to fit teaching Rust into lectures since you basically need all the concepts right from the start to understand a lot of programs. I never knew how to order things. The flip side was that usually when you understand all the basic components in play lots of it just fits together. i.e. there's some point where the interwovenness turns from a barrier into something incredibly valuable and helpful. —Jana Dönszelmann Visio

Breaking the sorting barrier for directed single-source shortest paths

If you want to solve a tricky problem, it often helps to get organized. You might, for example, break the problem into pieces and tackle the easiest pieces first. But this kind of sorting has a cost. You may end up spending too much time putting the pieces in order. This dilemma is especially relevant to one of the most iconic problems in computer science: finding the shortest path from a specific starting point in a network to every other point.
