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.

help packing sound in <4k
I had a deeper look at 4klang, it looks like it's not really taking care of sound output, it's "only" creating the sounds and filling a buffer (I might be wrong, that level of assembly is soooooo over my head. still damn interesting to read, tho)

Is there an audio equivalent of SVG?
Another thing that comes very close is this: https://github.com/hzdgopher/4klang This is a synth supposed to produce a size-compact output suitable for demos and similar scenarios. It does not create a XML (merely the opposite) but the main point is that the principles are close to what you are describing.

Creating procedural audio for demos
Two resources that spring to mind are 4klang and this old article series by kebby that doesn't seem to be online any longer. Mirrored here.

help packing sound in <4k
Gopher also made 64klang, and in the examples here they're using mmsystem to push samples to the soundcard, so I'd be inclined to think that's a pretty good way to do it (if not the best way)

Procedural 3D mesh generation in a 64kB intro
The intro was released in 2017. We published the first part of the making off in 2018 (was discussed on HackerNews here: https://news.ycombinator.com/item?id=16842576). A few days ago, I remembered I had an unpublished draft and decided to finalize it.
We use OpenGL for rendering and the code is written in C++. We published the source code of other intros of GitHub. For example, this one should give you a good idea of how we do it (also we modernized our engine since that): https://github.com/laurentlb/Ctrl-Alt-Test/tree/master/F
For audio, we used the synth 64klang - https://github.com/hzdgopher/64klang
