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.

We Are Doomed: A pessimistic point of view of "modern software engineering"
Neither Apple nor Microsoft want any usable multiplatform graphics API. For this reason, none of them delivers such a thing.
If you want a multiplatform graphics API, you should use a library which implements such API on top of these native OS-specific APIs.
I have good experience with that one: http://diligentgraphics.com/diligent-engine/ I’ve used it couple times on Windows with D3D12 backend, and on Linux with GLES 3.1 backend.

The Ultimate Cross-Platform Rendering Engine?
Diligent Engine: They say their engine is the successor of bgfx, but I'm not rly into that topic.

Collecting the best C++ practices
Diligent Engine. A Modern Cross-Platform Low-Level 3D Graphics Library and Rendering Framework Tweet.
- Diligent Engine 2.5.3 is out: path tracing tutorials, render state cache, hot shader reload and more
- Good repos for beginners to browse that follow best modern C++ practices (including testing, static analysis etc...)
- Check out a new path tracing tutorial in Diligent Engine that shows how to use a render state packager to build pipeline states off-line and pack them into archive so that they can be loaded fast at run time.

Improving my CPP skills
Read other people's code (I recommend modern small to medium sized github projects, because large ones can be overwhelming) or else you will forever stay in your bubble of how things are done. For example, I had learned a thing or two by using (and code browsing) diligent engine's source.

A Rant on Developers
I'm not speaking out of my ass, either, I have very actively followed low-level development being done towards open-source engines such as Diligent and Wicked. I personally am a contributor to the latter engine, as well. It is baffling to me that independent developers don't support this platform.

3D and 2D: Testing out my cross-platform graphics engine
I don't see WASM/WebGPU changing anything when it comes to gaming, as an industry, personally. 3d visualizations and interactive websites? Yeah definitely a nice improvement over WebGL 2, if years late.
WebGPU is pretty far behind what AAA games are using even as of 6 years ago. There's extra overhead and security in the WebGPU spec that AAA games do not want. Browsers do not lend themselves to downloading 300gb of assets.
Additionally, indie devs aren't using Steam for the technical capabilities. It's purely about marketshare. Video games are a highly saturated market. The users are all on Steam, getting their recommendations from Steam, and buying games in Steam sales. Hence all the indie developers publish to Steam. I don't see a web browser being appealing as a platform, because there's no way for developers to advertise to users.
That's also only indie games. AAA games use their own launchers, because they don't _need_ the discoverability from being on Steam. So they don't, and avoid the fees. If anything users _want_ the Steam monopoly, because they like the platform, and hate the walled garden launchers from AAA companies.
(I work on high end rendering features for the Bevy game engine https://bevyengine.org, and have extensive experience with WebGPU)

What Are Const Generics and How Are They Used in Rust?
I was working through an example in the repo for the Bevy game engine recently and came across this code

WebAssembly Playground
That's possible. I did spend quite a bit of time tinkering with compiler flags, and followed the recommendations.
Some notes I found just now seems to agree with my results, though: https://github.com/bevyengine/bevy/issues/3978#issuecomment-...

Immediate Mode GUI Programming
I cannot recommend immediate mode GUI programming based on the limitations I've experienced working with egui.
egui does not support putting two widgets in the center of the screen: https://github.com/emilk/egui/issues/3211
It's really easy to get started with immediate mode, it's really easy to bust out some UI, but the second you start trying to involve dynamically resized context and responsive layouts -- abandon all hope. The fact it has to calculate everything in a single pass makes these things hard/impossible.
... that said, I'm still using it for https://ant.care/ (https://github.com/MeoMix/symbiants) because it's the best thing I've found. I'm crossing my fingers that Bevy's UI story (or Kayak https://github.com/StarArawn/kayak_ui) become significantly more fleshed out sooner rather than later. Bevy 0.13 should have lots more in this area though (https://github.com/bevyengine/bevy/discussions/9538)

ECS, Finally
I've also been enjoying building My First Game™ in Bevy using ECS. The community around Bevy really shines, but Flecs (https://github.com/SanderMertens/flecs) is arguably a more mature, open-source ECS implementation. You don't get to write in Rust, though, which makes it less cool in my book :)
I'm not very proud of the code I've written because I've found writing a game to be much more confusing than building websites + backends, but, as the author notes, it certainly feels more elegant than OOP or globals given the context.
I'm building for WASM and Bevy's parallelism isn't supported in that context (yet? https://github.com/bevyengine/bevy/issues/4078), so the performance wins are just so-so. Sharing a thread with UI rendering suuucks.
If anyone wants to browse some code or ask questions, feel free! https://github.com/MeoMix/symbiants

Intel CEO: 'The entire industry is motivated to eliminate the CUDA market'
These days, some game engines have done pretty well at making compute shaders easy to use (such as Bevy [1] -- disclaimer, I contribute to that engine). But telling the scientific/financial/etc. community that they need to run their code inside a game engine to get a decent experience is a hard sell. It's not a great situation compared to how easy it is on NVIDIA's stack.

Capturing the WebGPU Ecosystem
Most of Nanite (at least, everything but the LOD system, I haven't tried that part, and the compute rasterizer due to lack of storage image atomics because Metal lacks them...) is implementable in WebGPU actually.
I have a PR that does a lot of the same things (meshlets, visbuffer, material depth, two pass occlusion culling) open for Bevy https://github.com/bevyengine/bevy/pull/10164 that I've been working on, which uses WebGPU.
WebGPU is actually a pretty good API imo. It's missing some advanced features like raytracing, mesh shaders, and subgroup operations (coming soon!), but it can still do a lot.
The much bigger missing feature is "bindless" support (non-uniform arrays of bound resources). BindGroup overhead (and ergonomics) is a significant downside.
