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.

> Can you give me an example of a Haskell expression which isn't reverentially transparent (without unsafePerformIO)?
Yes: https://github.com/ncaq/debug-trace-var The trick, however, is not unsafePerformIO (destructive mutability has nothing to do with referential transparency in general) but with TemplateHaskell, as quoting has everything to do with referential transparency.
> But the bog standard FP definition is a real and useful concept.
Actually, it's rather tautological. It defines FP circularly (see my comment here: https://news.ycombinator.com/item?id=36152488). It says nothing more than the far more useful explanation: "the meaning of every expression is a value".
