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.

Static Type Safety with Variadic Functions: an Idea and a Question
For further reading, there's a paper on arity generic programming and some solutions using dependent typing in Agda.
-
When do you find it better to use non-ASCII identifiers?
In Rust I have never seen it. However, in Agda it's a convention, and the code looks beautifully https://github.com/agda/agda-stdlib/blob/master/src/Algebra/Lattice/Structures.agda
-
Should programming languages switch to special characters (gliphs) for it's code?
Agda is a good example, as it allows you to define arbitrary Unicode-based operators and names: https://github.com/agda/agda-stdlib/blob/master/src/Data/Product.agda
-
Separating the type and value namespaces?
Most of the times you want the first three arguments to be passed implicitly, not just the first. And the syntax for passing arguments implicitly is the same for the type argument A and the term arguments n and m. (For Agda, see e.g. l.49 here: https://github.com/agda/agda-stdlib/blob/master/src/Data/Star/Vec.agda)

Are There People Doing Formal Math In Berlin?
I just wonder if there are any irl meetups of people involved with formalizing mathematics, I thought that it would be a cool hobby to pick up (with some background in math and programming) but the existing libraries, like MathLib, TypeTopology or UniMath look a bit intimidating...
What are some alternatives?
cryptominisat - An advanced SAT solver
Agda - Agda formalisation of the Introduction to Homotopy Type Theory
l4v - seL4 specification and proofs
Coq-HoTT - A Coq library for Homotopy Type Theory
agdarsec - Total Parser Combinators in Agda
cubicaltt - Experimental implementation of Cubical Type Theory
template-agda - An Agda template, configured for Gitpod (www.gitpod.io) to give you pre-built, ephemeral development environments in the cloud.
UniMath - This coq library aims to formalize a substantial body of mathematics using the univalent point of view.
creusot - Creusot helps you prove your code is correct in an automated fashion. [Moved to: https://github.com/creusot-rs/creusot]
mathlib4 - The math library of Lean 4
next-700-module-systems - PhD research ;; What's the difference between a typeclass/trait and a record/class/struct? Nothing really, or so I argue.
