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.

What are some SOLVED mysteries?
It's a long way away from research-level, but there is real progress; now, I don't see how things like topology and such like will be formalized soon, having to write down explicit transformations for things instead of just saying "this is clearly such a transformation", but I've been impressed.

Is there a book like Russell's Principia Mathematica but for modern day mathematics?
Re your second para: you make speculations, but here are the facts. There certainly is a bunch of interest right now in formalising mathematics, there are fully paid-up mathematicians like myself hanging out on the Lean chat, working on stuff like this -- undergraduates, PhD students, post-docs and permanent staff. The repo is here and it's coming along nicely. Movement is happening. But it will be a while before we can convince the "generic mathematician" that these tools are useful. The Scholze project linked to in those links above is just another data point, but I fear we will need many more.

CS251: Great Ideas in Theoretical Computer Science (CMU)
Source code for the second book:
Use DieHard to avoid crashing newer window managers such as CWM:
-
KamilaLisp – A functional, flexible and concise Lisp
Check out stutter from the Computational Beauty of Nature too:
cat data/demo.lisp | ./bin/stutter
Have a look on the file on how integers and aritmetics are implemented.
The books explains that, but is not free. But you can get it somewhere else.

Old Math Software from 1990s
From the The Computational Beauty of Nature:
If you use CWM as your window manager, it might crash as some of the software only works fine

“A damn stupid thing to do”–the origins of C
On C, compilers in the 90's sucked up a bit, and the code wasn't much better.
Consider this:
This code crashed CWM under OpenBSD 7.2, but it worked under FVWM.

Summer Book Recommendations?
This is a really unique book, but it is quite dated as the graphics/simulations are written in C (https://github.com/gwf/CBofN). But I don't think the book text has any code in it nor does is it necessary to read the code to read the book. Rather it is mostly conceptual with some mathematics.
