The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

My subtraction algorithm always generates 6 cuboids, except when there is no intersection. It then discards the ones with size 0.

Rust https://github.com/Crazytieguy/advent-2021/blob/master/src/bin/day22/main.rs Imagining the geometry of this was very tricky for me. For a while I contemplated if calculating the intersection of each pair of cuboids would give me enough information to know how many cubes are on at the end, and finally decided that I would also have to calculate the intersections of those and so on, so I gave up. Instead I decided that my state will be a vector of cuboids that are garuanteed to be non overlapping, and on each command I would subtract the current cuboid from each of these non overlapping cuboids (leaving 1 to 6 cuboids depending on intersection), and finally either add in the current cuboid (for on command) or leave it out (for off).
