i’m not doubting this, but do you know if there are any studies on this already?

we make extensive use of simd at work, usually through highway: https://github.com/google/highway

imo this is one of the greatest libs ever written. it handles dynamic dispatching of correct simd instructions / lane widths for various hardware with just one simd loop written (handling NEON/AVX/AVX2/AVX512/extensions) with comparable performance to handwritten native intrinsics

this isn’t the point of the story, but is that paint truck driving on the railroad tracks?

i may be missing context, but shared memory across processes, without ipc?

this is a way smaller deal than acr. i personally don’t connect my smart tv to my network and use an apple tv instead

Hmmm... In the code (https://github.com/andrewmccalip/kickbacks.ai/blob/main/src/...) the extension polls for updated every 90 seconds and has no digital signature verification... So get a bunch of people to install and issue a malicious update and within 90 seconds, your entire user base has it? I'm good

Hey guys, author of numpy-ts here. Just sharing some (potentially-obvious) learnings while optimizing the library :)

the customer testimonials were enough to earn my github star

Show HN: NumPy for Browser, Node.js, Deno and Bun

dupontcyborg — Wed, 25 Feb 2026 19:54:24 +0000

I've been spending some time on a side project, `numpy-ts`, which is a TypeScript numerical library inspired by NumPy. It aims to bring the same NumPy API (where possible) to Node.js/Browser/Deno/Bun with full .npy/.npz compatibility (read & write).

It currently has 476 of NumPy's 507 functions implemented, all cross-validated against NumPy with >6,000 validation tests. The lib is about 93 kB minified+gzipped and has zero dependencies, and it's fully tree-shakeable.

Since it's written in TypeScript, it's on average 15x slower than NumPy. I just tagged 1.0.0, and will begin performance optimization soon (both algorithmic and selective WASM for fused kernels).

You can try it in your browser here: https://numpyts.dev/playground

Disclaimer that this was a mix of hand-written code (API, deterministic tooling) and AI-assisted (functional implementations, validation test implementations).
