dupontcyborg··on Kitesurf: Agent-first browser that runs in V8 isolates
kinda meta to have a js engine built in rust, compiled to wasm, running in cloudflare workers which itself is another js engine (v8 isolates)
dupontcyborg··on Don't be a meat proxy
i’m not doubting this, but do you know if there are any studies on this already?
dupontcyborg··on Everyone should know SIMD
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

dupontcyborg··on Everyone should know SIMD
this would be amazing
dupontcyborg··on Painting the sides of railroad rails white to reduce derailment
this isn’t the point of the story, but is that paint truck driving on the railroad tracks?
dupontcyborg··on Postgres rewritten in Rust, now passing 100% of the Postgres regression tests
i may be missing context, but shared memory across processes, without ipc?
dupontcyborg··on Nearly Half of LG Smart TV Apps Contain Residential Proxy SDKs
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
dupontcyborg··on Kickbacks.ai – Get Paid for Waiting
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
dupontcyborg··on Making NumPy-ts as fast as native
Hey guys, author of numpy-ts here. Just sharing some (potentially-obvious) learnings while optimizing the library :)
dupontcyborg··on Show HN: Kyushu – A self-hostable WASM sandbox for JavaScript workers
the customer testimonials were enough to earn my github star
dupontcyborg··on NumPy-Ts: NumPy for Browser and Node.js
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

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