Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Extism Makes WebAssembly Easy
Indeed, webassembly is moving extremely slowly. I started a project years ago expecting https://github.com/WebAssembly/memory-control/blob/main/prop... and https://github.com/WebAssembly/memory64 to be fixed at some point. Neither are yet, and the project still suffers from it to this day.
I think wasm is still great without these fixes, but I have lost confidence in the idea that wasm will reach its full potential any time soon.

The Tug-of-War over Server-Side WebAssembly
Additionally, googlers are championing memory control https://github.com/WebAssembly/memory-control/blob/main/prop..., which provides memory protection.

How do Rust WebAssembly apps free unused memory?
But researching it a bit I found this issue, so it clearly seems to be a problem for a bunch of people out there. And apparently both V8 and Spidermonkey have already addressed this quite recently, see this issue.

WebAssembly and C++
FWIW there is a proposal in the works to add page-based protection, which will allow unmapping the 0 page, restoring the trap-on-null-deref behavior that is important for many languages with safety checks.

The IMPOSSIBLE RISCV HACK: Vector Extension 0.7.1-draft w/ current Linux kernel! – René Rebe
I'd love to see OpenCL or WasmSIMD support for RVV 071.

WASM vs Native Rust performance
Wasm SIMD supports only 128-bit registers, no? https://github.com/WebAssembly/simd/blob/a78b98a6899c9e91a13095e560767af6e99d98fd/proposals/simd/SIMD.md

A Look at Performance in Wasmtime and Cranelift
According to the WebAssembly Roadmap, the 128-bit packed SIMD Extension proposal has been accepted and is already implemented in every major runtime except Safari, and the Relaxed SIMD proposal is planned, with Firefox already having an experimental implementation in nightly-channel builds.

There are many like it, but this is my Rust raytracer running in WebAssembly
Thanks! You're probably right about spatial filtering with a low sphere count. SIMD is supported, that looks to work in every recent browser except Safari. Looking forward to trying that out. A really quick search of wasm-bindgen docs don't reveal an interface to use that SIMD support though. I wonder if you can unsafely inline some raw wasm like you can with asm!
