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.

Ask HN: Is writing a math proof like programming without ever running your code?
Quickcheck is a Haskell testing library which allows the programmer to write propositions about how a function should behave, and the library will try to find cases which falsify the proposition.
If my understanding is correct, it can't "prove" any properties, only disprove them.
For concretely proving properties of a program, you would need something like Idris's dependent type system, where you can prove that a function always returns a sorted list, for example.

Is anyone using quickspec?
It looks like that change is on github, but the version wasn't bumped, nor was it pushed to hackage https://github.com/nick8325/quickspec/blob/master/quickspec.cabal Perhaps try using github as the source instead of hackage?

Reverse of quickspec
Quickspec (https://github.com/nick8325/quickspec) is awesome in discovering laws in the code we write. But I am in search for a tool (the reverse) , which given the spec, can it synthesise code ?
What are some alternatives?

HUnit - A unit testing framework for Haskell
hspec-wai - Helpers to test WAI applications with Hspec
tasty - Modern and extensible testing framework for Haskell
quickcheck-state-machine - Test monadic programs using state machine based models
