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.

Friendship ended with Monads: Testing out Algebraic effects in OCaml for Animations
I would argue that the fact that not all monads compose is a feature, not a bug, in that not all effects are compatible. Citing from in-other-words:

-
GHC.Num: Why no multiplication commutativity?
Linear.Quaternion.Quaterion from the linear package has a Num instance, and quaternion multiplication is noncommutative.
-
Is there an existing typeclass for differences?
That's pretty much exactly the abstraction used in the 'linear' package's Affine class, in which we find points separated by vectors.
-
What are the current challenges in Numerical Programming for Haskell?
Linear algebra: hmatrix again with its own array type (and linear but this is restricted to low dimensions)
-
Advanced programming exercises/apps recommendations to code
This is very niche, but something I've wanted to do for a while is to generate some cool physics example on the surface of a sphere with https://hackage.haskell.org/package/hamilton, and display it with https://reanimate.github.io/ (using https://hackage.haskell.org/package/linear for the projection)

How to create my Functor / Eq / Num combination on Coords?
Do check out the linear package. It has some complicated parts, but the types work out very nicely. Your Coords type is called V3 in that package, it has a huge list of instances for all kinds of different type classes.

Probabilistic modelling in Idris: engineering as research
I've come to love the linear approach, where instead of working with Naperian (Representable) functors, you work with Distributive functors.

Monthly Hask Anything (June 2021)
See also the linear library, it contains types like data V3 a = V3 a a a with all of the useful instances.
