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 Thoughts on OCaml
https://github.com/morganstanley/hobbes
Things like structural equality and ordering are user functions here rather than magic internal definitions (e.g. equality is defined as a type class, and type class instances can deconstruct algebraic types at compile time to decide how to implement instances). But evaluation is eager by default, so it's pretty easy to reason about performance. And data structures can be persisted to files and/or shared transparently in memory with C/C++ programs without translation, also very convenient for the places where this was used. Actually we built some very big and complicated time series databases with it, used in both pre and post trade settings where ~15% of daily US equity trades happen. So I think these observations are useful and have passed through some pretty significant real tests.

Peridot: A functional language based on two-level type theory
https://github.com/morganstanley/hobbes
This approach has several benefits, but there's a lot of appeal also to the way they're doing it, to have the same PL across stages (and then maybe have more than just two stages).
