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.

linear

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)
