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.

GHC Proposal breakage: should we proceed?
Inferred variables as a concept seems to be against "Explicit Variable Principle (EVP)" (mentioned in https://github.com/goldfirere/ghc-proposals/blob/type-variables/principles.rst, linked from https://github.com/ghc-proposals/ghc-proposals/pull/448). I agree with that priciple.

[ANN/RFC] constraint-rules
I can't get it installed but does it allow deriving instances that need higher-order roles? The second argument of GList f a has a nominal role so we can't coerce through it but it should be representational if f is Representational1
