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.

Low overhead C++ interface for Apple's Metal API
> The specific method that's causing me trouble right at the moment is "computeCommandEncoder"
Yeah, it looks like there's no way to avoid autorelease here.
> It looks like objc_retainAutoreleasedReturnValue might be exactly what I'm looking for, even if it isn't 100% guaranteed; if I'm understanding, it would be safe, and wouldn't actually leak as long as you had an autorelease pool somewhere in the chain.
Indeed it would be safe and wouldn't leak, but the optimization is very much not guaranteed. It's based on the autorelease implementation manually reading the instruction at its return address to see if it's about to call objc_retainAutoreleaseReturnValue. See the description here:
https://github.com/apple-opensource/objc4/blob/a367941bce42b...
In fact – I did not know this before just now – on every arch other than x86-64 it requires a magic assembly sequence to be placed between the call to an autoreleasing method and the call to objc_retainAutoreleaseReturnValue.
It looks like swiftc implements this by just emitting LLVM inline asm blocks:
%6 = call %1* bitcast (void ()* @objc_msgSend to %1* (i8*, i8*, %0*)*)(i8* %5, i8* %3, %0* %4) #4

Building the DirectX shader compiler better than Microsoft?
And wgpu has been doing this for years. Things like descriptor indexing are not exposed to the web but used by Rust (mostly) engines on native.

If they used https://wgpu.rs/ they would get directx and metal for free (:

Show HN: WebGPU Particles Simulation
IIRC it was delayed multiple times. I think the first intent to ship from chrome was before 100 but they kept pushing it off. Firefox still does not support it. There are projects like wgpu[0] that wrap provide a higher level API and I have used some projects using it with no issues. WFIW I didn't see any issue with OP's demo either.

There is anything like wgpu.rs for Zig?
There is anything like wgpu.rs for Zig? wgpu.rs is an abstraction on top of Vulkan, Metal, DirectX, etc...
What are some alternatives?
metal-cpp - Metal-cpp is a low-overhead C++ interface for Metal that helps developers add Metal functionality to graphics apps, games, and game engines that are written in C++.
vulkano - Safe and rich Rust wrapper around the Vulkan API
MoltenVK - MoltenVK is a Vulkan Portability implementation. It layers a subset of the high-performance, industry-standard Vulkan graphics and compute API over Apple's Metal graphics framework, enabling Vulkan applications to run on macOS, iOS and tvOS.
