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.

For, Map and Reduce in Elixir
One of the students in my Introduction to Functional Programming course recently submitted a code snippet. It became evident that they assumed Elixir's 'for' construct operates similarly to 'for' loops in non-functional programming languages. However, this is not the case, as Elixir's 'for' is fundamentally different in its behavior.

How programmers make sure that their software is correct
> There are generally two main categories of tests. There are unit tests [and] Integration tests
Later on there is a mention of fuzzing. However, there is something better called property tests. Where the on failure there is automatic "shrinking" of input complexity to find a minimally failing test scenario.
For Erlang and Elixir I recommend https://propertesting.com/ book and the PropEr test framework https://github.com/proper-testing/proper.
As an example, here is the use of an advanced feature called targeted property based testing: https://proper-testing.github.io/tutorials/PropEr_testing_wi... used to test a labyrinth.
