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.

Olive.c: a simple graphics library that does not have any dependencies
Yeah PortableGL will never be completely fully featured, not even for OpenGL 3.3 since I'll definitely never do the geometry shader and probably not the transform feedback. But specifically it'll never have the earlier immediate mode stuff, or some of the big 4.0 stuff like the tessellation shaders. I have been meaning to add the DSA functions where they make sense. They'd be really simple to implement.
Actually a few days ago someone sent me a pull request adding an interesting project to my README
https://github.com/rswinkle/PortableGL/commit/e0652b4dff266d...
So now if I were to try to sum up all the OpenGL software implementations I can think of,
TinyGL (and modern improved forks) = OpenGL 1.1-1.3 ish

PortableGL: An implementation of OpenGL 3.x-ish in clean C
Not entirely related to the subject of OpenGL, but I really like how the author has decided to lay out this project. It's pretty hard to beat the convenience of a single header (or single header/single source) distribution for C libraries, but library development gets progressively harder as the project gets bigger as more code is added to the (usually hard to navigate) header file. Here, the author does their development with multiple files as one normally would, but when a new version is released they run the generate_gl_h[1] script that concatenates everything into a .h file for distribution. Simple yet flexible! This is also how SQLite[2] distributes its builds. It's a pattern that I'm using myself in some unreleased projects.

Don't waste money on a math coprocessor they said;
K5/Cyrix could overlap Integer and FPU operations, what they couldnt do was interleave (pipeline) FPU operations so that multiple floating point instructions ran in parallel.

Honestly don't understand why people keep buying from them
Quake seriously wasn't any more complicated. The only thing about Quake that really made it stand out was its 3D engine which, while revolutionary for its time, was basically stone-age technology by modern standards.

You can also read this very old CPMA code that reimplements bunny hopping into Quake 3, a link I'm able to dig up because I have also been playing since literally the first one came out.
