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.

Ask HN: Released games built on FOSS engines?
Oh, I forgot a few major ones:
https://github.com/ConfettiFX/The-Forge was used in No Man's Sky, Hades and Starfield.
https://github.com/jrouwe/JoltPhysics is the physics engine in Horizon Forbidden West.
- The Forge 1.53: Steam Deck support, dropped EASTL containers, docking imgui

How many semaphores do really I need?
To my understanding, every source I've read says that this should cause issues, but in practice it doesn't. What gives? Did I miss something? Here are multiple examples using the latter approach.

Amnesia TDD HPL2 refactor
This is a toy project that I've been working on for the past few months. Essentially, I've rewritten all the rendering code for the engine using BGFX. This means that all the fixed function OpenGL 1.2 code has been removed from the engine. BGFX supports OpenGL 3.3 and DirectX11, but there are still some rendering artifacts with DirectX11, so the engine still uses OpenGL when running on Windows. I've been considering switching to The Forge (https://github.com/ConfettiFX/The-Forge) if I want to have more control over the rendering pipeline. However, this is a complex topic with significant implications for the codebase. I've already done the hard work of eliminating clumsy abstractions in the engine and simplifying the render pipeline, so it's just a matter of deciding what direction I want to take.

Some information about the Creation Kit changes for Starfield.
So, I'm not sure if it is widely known, that Starfield is going to be running on a lot of "The Forge." The creators of The Forge says it was added to Creation Kit in 2019. This will open a LOT of new systems for Bethesda games.

Writing a TrueType font renderer
Great to see more accessible references on font internals. I have dabbled on this a bit last year and managed to have a parser and render the points of a glyph's contour (I stopped before Bezier and shape filling stuff). I still have not considered hinting, so it's nice that it's covered. What helped me was an article from the Handmade Network [1] and the source of stb_truetype [2] (also used in Dear ImGUI).

Capturing the WebGPU Ecosystem
So I read through the materials on mesh shaders and work graphs and looked at sample code. These won't really work (see below). As I implied previously, it's best to research/discuss these sort of matters with professional graphics programmers who have experience actually using the technologies under consideration.
So for the sake of future web searchers who discover this thread: there are only two proven ways to efficiently draw thousands of unique textures of different sizes with a single draw call that are actually used by experienced graphics programmers in production code as of 2023.
Proven method #1: Pack these thousands of textures into a texture atlas.
Proven method #2: Use bindless resources, which is still fairly bleeding edge, and will require fallback to atlases if targeting the PC instead of only high end console (Xbox Series S|X...).
Mesh shaders by themselves won't work: These have similar texture access limitations to the old geometry/tessellation stage they improve upon. A limited, fixed number of textures still must be bound before each draw call (say, 16 or 32 textures, not 1000s), unless bindless resources are used. So mesh shaders must be used with an atlas or with bindless resources.
Work graphs by themselves won't work: This feature is bleeding edge shader model 6.8 whereas bindless resources are SM 6.6. (Xbox Series X|S might top out at SM 6.7, I can't find an authoritative answer.) It looks like work graphs might only work well on nVidia GPUs and won't work well on Intel GPUs anytime soon (but, again, I'm not knowledgeable enough to say this authoritatively). Furthermore, this feature may have a hard dependency on using bindless to begin with. That is, I can't tell if one is allowed to execute a work graph that binds and unbinds individual texture resources. And if one could do such a thing, it would certainly be slower than using bindless. The cost of bindless is paid "up front" when the textures are uploaded.
Some programmers use Texture2DArray/GL_TEXTURE_2D_ARRAY as an alternative to atlases but two limitations are (1) the max array length (e.g. GL_MAX_ARRAY_TEXTURE_LAYERS) might only be 256 (e.g. for OpenGL 3.0), (2) all textures must be the same size.
Finally, for the sake of any web searcher who lands on this thread in the years to come, to pack an atlas well a good packing algorithm is needed. It's harder to pack triangles than rectangles but triangles use atlas memory more efficiently and a good triangle packing will outperform the fancy new bindless rendering. Some open source starting points for packing:

Www Which WASM Works
The STB headers are mostly built like that: https://github.com/nothings/stb
You could also add an optional 'convenience API' over the lower-level flexible-but-inconvenient core API, as long as core library can be compiled on its own.
In essence it's just a way to decouple the actually important library code from runtime environment details which might be better implemented outside the C/C++ stdlib.
It's already as simple as the stdlib IO functions not being asynchrononous while many operating systems provide more modern alternatives. For a specific type of library (such an image decoder) it's often better to delegate such details to the library user instead of circumventing the stdlib and talking directly to OS APIs.

My stuff for instance:

...inspired by:

But it's not so much about the build system, but requiring a separate C/C++ compiler toolchain (Rust needs this, Zig currently does not - unless the proposal is implemented).
