Show HN: Faux radio website instead of texting MP3s

Hacker News - Thu, 02/12/2026 - 9:39am

I'm a synth developer and musician, I text people MP3s A LOT. I was cleaning up my phone storage recently and realized it stores a new copy of the MP3 every time I send it to someone, so I've got 25 or 50 copies of some of these files sitting around. I built this site to take my folder of samples / demos and serve 'em up sort of like a radio station, making it easy to share, re-share, listen, store one place, etc. Enjoy!

Ask HN: Why does no one talk about the H-1B problem?

Hacker News - Thu, 02/12/2026 - 9:39am

It seems like the only circles online discussing abuse of the nonimmigrant system in the US are right wingers.

Why is everyone else not concerned with the obvious ethnic nepotism, often caste based too, among primarily indian nationals? I have watched entire teams and companies get overrun with foreign nationals, while Americans have been laid off.

It is 1000% not a skill issue, the foreign nationals are often worse at the job, but it doesn't matter because realistically most of these companies can coast on their products with a skeleton crew of competent engineers that pickup the slack.

How can we seriously claim that we are facing a shortage of engineers, justifying hiring foreign nationals, when hundreds of thousands have been laid off over the last 5 years?

Obviously this applies to all nonimmigrant visas, and all foreign nationalities, but with indians making up ~80% of H-1B's specifically, they're not even trying to hide it. The trucking industry, something I'm very familiar with, has also been devastated by the same ethnic cartel.

If this post is flagged, I think it's obvious who is upset I am pointing this out. It is not intended to be racist, or inflammatory. This is a serious discussion, of a serious issue.

It's not lost on me that this website is full of indians who will probably take offense. But it's not a good look to defend this and will only amplify contempt for foreign workers.

Show HN: Crashcat – Lightweight 3D physics for JavaScript

Hacker News - Thu, 02/12/2026 - 9:37am

Hi HN,

I made crashcat, a lightweight 3D physics library for JavaScript games and creative websites.

Existing WASM physics libraries you can find on npm today are performant, but sometimes you just want a little capsule guy to run around on a mesh without downloading a ~3mb WASM file. They often require manual memory management, which feels a bit alien in JavaScript and is easy to mess up.

My view on WASM is becoming: go all in, or all out. Having physics state in WASM and game state in JavaScript is an architectural wart. Just build a C++ or Rust engine if you want the best result! But if you want something simple in JS, crashcat can serve that better.

Some existing pure JavaScript libraries solve the bundle size problem but miss useful features like shapecasting, CCD (continuous collision detection, prevents fast moving bodies "tunneling" through other bodies), and fast raycasts.

The library is written in TypeScript and designed to be highly tree-shakeable. Only need boxes and spheres? Your bundler will strip out all the collision logic for triangle meshes, convex hulls, etc.

It supports rigid body simulation with various convex shapes, triangle meshes, and compound shapes. It uses GJK/EPA for collision detection, has CCD, broadphase spatial acceleration with a dynamic bounding volume tree, and APIs for world queries like raycasts and shapecasts. It's library agnostic.

Give it a try!
