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.

MetricsController, a gem for RoR to automate some routine procedures at an outsourcing company
That solution suits our needs perfectly, we will keep maintaining the tool in the future. It's open source so you can check the project in our official repository.

There's a pretty good Ruby gem I've used for this before:

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
