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.

Issue 302 :: Haskell Weekly newsletter
In main branch of distributive, Distributive is gone. There is only Representable. See current state https://github.com/ekmett/distributive/blob/117377d7ba38efc5b115169b565dfb80de8ad407/src/Data/Rep/Internal.hs

Monthly Hask Anything (November 2021)
Seems like a neat signature. Is it an instance of some deeper concept or property? Is there a general typeclass for it? It looks a little bit like distribute from distributive.

A decade of developing a programming language
I highly recommend https://github.com/sdiehl/write-you-a-haskell as it is very developer friendly. It’s not complete, but it really gets the gears turning and will set you up for writing your own Hendley-Milner style type checker.

Monthly Hask Anything (November 2021)
I feel like Write You A Haskell was set out to introduce some of these foundational concepts in the right order: lambda calculus, to system-f to core - but that's more of a skeleton, right? What about logic? proofs? Is there anything else ... that can all be put together to create a "course" of some sort to master the theoretical concepts that Haskell stands upon?
