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.

converting a vec4 into a mat4
It's too bad you are using C. If you were using C++, you could use teh fantastic GLM library, which implements the vector math stuff from GLSL as CPU/C++ code. you might want to have a look at CLGM: https://github.com/recp/cglm

Matrix multiplication in C
There's cglm, but I don't know how good it is. Really though for hobby OpenGL stuff, it's going to be 3x3, 4x4, 1x4 matrices, so rolling one's own stuff is not that terrible, if it proves to be a bottleneck (probably won't), you can drop in some fancy SIMD bullshit later.

In what way should I write a matrix library for my OpenGL game?
There is a cglm: repo

What can I replace the C++ code "Vector3f" with?
Check out https://github.com/recp/cglm I use it judiciously.

I want to make a game for Linux. Where do I even start?
GLM and CGLM should probably be mentioned as well since you'll probably want a good linear algebra library if you are going with just a rendering library instead of a full game engine.

What would be the best way to implement a (algebra) vector in C (for OpenGL purposes)?
cglm has two options for representing a vector: using a struct and using an array. The default one is using an array, but I'm not seeing what are the benefits of using an array instead of a struct. When using an array, you need to use out parameters, which make the code much more ugly when doing multiple operations. Using a struct, I can simply return the struct from the function. The only advantage of using an array would be that it's easier to iterate through it, but I could do the same using structs like this

Using CGLM, why does the value of this vec4 affect the mat4?
It has been a while since I've written any C so it's very likely I'm missing something very simple. But I'm using CGLM and I have this simple program:
