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.

Code coverage vs mutation testing.
You should only really care about mutation testing if your code coverage is relatively high. If your code coverage is 20% then mutation testing should not be your priority. We use mutation testing (mutant for Ruby, pitest for Java). mutant is pretty hassle-free but only works when running under MRI so if you use jruby you are out of luck. pitest was far less easy to integrate.

Semantic blind spot in Ruby case statement
mutant shows redundant semantics, why we'd like to reduce them is perhaps better explained at https://github.com/mbj/mutant#what-is-mutant

MatrixEval - A local alternative to GitHub Action/Circle CI/Travis CI matrix job. Simply run your code against different versions of dependencies.
appraisal can not do combination with multi Ruby versions. Check this issue: https://github.com/thoughtbot/appraisal/issues/182. appraisal users have to use CircleCI to do those things. But MatrixEval can combine all things, including Ruby version, everthing is up to you.
