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.

Nebula is an open-source and free-to-use modern C++ game engine
Have you considered not using an engine at all, in favor of libraries? There are many amazing libraries I've used for game development - all in C/C++ - that you can piece together:
* General: [stb](https://github.com/nothings/stb)
- STB: Single-file public domain libraries for C/C++

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.

File for Divorce from LLVM
My stuff for instance:
https://github.com/floooh/sokol
...inspired by:
https://github.com/nothings/stb
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).

[Noob Question] How do C programmers get around not having hash maps?
stb_ds is also very popular.

OSS Game Engines are increasing their stars on GitHub due to Unity's missteps
For anyone interested, LibGDX[1] is a very nice open-source game engine for Java. It is cross-platform (mobile, PC/mac, web). Very popular and well maintained, too.

(Java) Is there any way to convert InputStream to temp File without OutputStream?
And let me explain, for example jorbis this library has a lot of nested loops in it, i understand why this library using this, but this is really bad. Because when I am trying to use library with this code, this taking so much time to convert ogg to pcm, and yes I know that converting ogg to pcm is a hard process, but I need to optimize my program, make it more better. The main thing is EVERY decoding ogg file library using the same piece of code! And I am not joking for example libgdx.

(Java) How to .ogg file convert to pcm?
What the pcm file contains? And what is the structure? What data I should use for converting .ogg file into pcm? Is there any information about pcm files? Is there any repositories in github that converts .ogg files into pcm? (I am already know there is JVorbis, libgdx and jorbis but thats not what i want)

Instancing/Instanced Rendering in LibGDX (3D)
I found an example for rendering a [Mesh] object using instancing in LibGDX's tests (link), but I'm not sure how to apply that for rendering actual models.

Is there anything like PICO-8 for Java?
Many newer Java games on Steam use libGDX. Older games used Slick2d. Both APIs mimic Java2D, the standard library API, which itself is good enough when you are starting out.

What's the status of game dev and GC pauses in Java since JDK 16?
Also, according to https://github.com/libgdx/libgdx, libGDX has around 45% of source codes written in C++ and C, while only 53.3% are written in Java.

What software do you use to draw the UI?
I'm using LibGDX TexturePacker2 standalone version to pack images into atlases. I wrote my own .atlas file parse that loads the files (it's a very simple textual format).
