On: Measuring the impact of AI on experienced open-source developer productivity

For certain tasks it can speed me up 30x compared to an expert in the space: https://rust-gpu.github.io/blog/2025/06/24/vulkan-shader-por...

This is very disingenuous: we don't know how much spare time Sascha spent, and much of that time was likely spent learning, experimenting, and reporting issues to Slang.

[LegNeato → lpghatguy]

It's not disingenuous, we have his and my git commit logs. I also had to deal with issues with rust-gpu. He is an expert in both the space and his project, I had never seen his project nor written any graphics shaders before. You can never get apples to apples comparisons but this is the closest I have personally experienced.

GraphQL is transport agnostic

I worked at an auto parts retailer growing up in high school. I had very basic knowledge of cars. After working there for a year, someone could come in and describe what they were seeing and hearing and 80% of the time I could tell them what is wrong and what is needed. You'd be surprised at how a large population is similar for different 'paths' through the problem and solution space

Surprised this doesn't mention candle: https://github.com/huggingface/candle

I don't think that fits; that's a ML framework. The others in the link are general GPU frameworks.

Surprisingly, it seems this project just supports Spir-V and PTX, but not DXIL or AMDGCN.

I say surprisingly, because I'd expect Rust support to be more mature than Zig's.

[lostmsu → ladyanita22]

Microsoft indicated they are switching to SPIR-V from DXIL: https://devblogs.microsoft.com/directx/directx-adopting-spir...

I have a WIP naga backend that converts glsl and hlsl to rust-gpu shaders.

On: Shadertoys Ported to Rust GPU

[LegNeato]

Yes. Under the hood it uses wgpu and naga, which translates the SPIR-V into metal so it runs iOS and macOS (on Linux and Windows it uses spirv on vulkan directly)

[LegNeato]

wgpu is CPU side, rust-gpu is GPU side. The projects work together (our latest post uses wgpu and we fixed bugs in it: https://rust-gpu.github.io/blog/2025/04/10/shadertoys )

On: Rust CUDA Project

[LegNeato]

Maintainer here. It works on recent rust and latest CUDA. See https://rust-gpu.github.io/blog/2025/03/18/rust-cuda-update

[LegNeato]

You can look to https://github.com/Rust-GPU/rust-gpu/ for vulkan.

[shmerl → LegNeato]

That's a good example of of what it should be.
