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.

witherable
-
CS SYD - A dancing space leak
Generic operations: mapMaybe and the witherable package are two good examples.
-
Version 0.6 of Flat, a principled, portable and compact binary data format
Yes or if you have instances of the polynomial functors, you can create a trivial instance like https://github.com/fumieval/witherable/issues/89
-
A functor is a container that implements map. Is there a special name for containers that implement filter or reduce?
I think filter would correspond to the Filterable class from witherable.

Name of operation
I'm not sure about the parts of the above implementation like takeOne though. I've used this takeOne few times. Also, traverse combined with catMaybes is a pattern captured in witherable package. Like this:
What are some alternatives?
