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.

Improving our safety with a physical quantities and units library
Scala's squants library is a nice implementation of units-of-measure/dimensional-analysis http://www.squants.com
In particular it uses types for dimensions; whilst units are just constructors. Hence `Meters(2)` and `Microns(7)` have the same type (`Length`).

Atlas, a (hopefully) better engineering IDE
You might find the Squants library for Scala interesting; it even seems like an apt usage of some oft-questioned language features.
