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.

Permutation Iteration and Random Access
Here is Lisp code [1] that maps all sorts of combinatorial objects—permutations, bit sets, base-B integers, multi-set permutations, etc.—perfectly into the smallest set of integers [0, n-1] and back. (In a sense, it's a perfect hash.) This is used to efficiently solve combinatorial puzzles.

Can a Rubik's Cube be brute-forced?
Note that in the unlikely event anyone wants to run the code in the post, the algorithm presented is still in an open PR, APIs change until merged, etc.
- Favorite Lisp project? Shameless plugs welcome & encouraged!
