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.

Vector math library benchmarks (C++)
I'm definitely interested in any thoughts you guys may have on the benchmarks, and am definitely open to contributions adding additional benchmarks/vector math libraries! For example, one that I thought about adding but didn't simply because it seems to have fewer game-centric features is RTM.

How do other motion capture suits manage large file sizes?
Cleaned and compressed are whatever they turn out to be. Use ACL, https://github.com/nfrechette/acl

I converted a massive library of mo-cap animations to .fbx which you can use freely with ALMOST no restrictions
For such animations make sure to check out ACL (animation compression library) by /u/zeno490. There are some stats and implementation details on how well it works on his blog: http://nfrechette.github.io/

Rasterization in slow motion
Yep. That lib is great. And, similarly https://github.com/nfrechette/acl and https://github.com/BinomialLLC/basis_universal

What's the reason why some newer games are really huge in size?
At the minimum BC compression is used for most textures and Crunch is pretty popular so we're definitely never ignoring that end. Draco (for geometry) isn't as popular as it should be. Animation is the main area that gets skimped and we're mostly still just doing crude keyframe reduction as stuff like ACL (https://github.com/nfrechette/acl) hasn't really taken off (it has a shit API and shit examples).

What interpolating method should I use to interpolate between two scale key frames of a skeletal joint? I currently LERP between position keys, and SLERP between orientation(quaternion) keys. Should I also just use LERP for scaling? I remember reading somewhere to use a log function.
Animation compression is a science in itself. https://github.com/nfrechette/acl is a pretty serious project for that.
