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.

Symbolics.jl: A Modern Computer Algebra System for a Modern Language
Hey, I have... I'm a co-author of Algebird[0], which has many ideas that I'd pull over.
I'm hoping to introduce Clojure's "spec" or "schema" libraries so that the types at play can at least be inspectable inside the system. In a fully typed language, I'd implement the extensible generics as typeclasses.
I suspect it would make it quite a bit tougher (at least in the approach I'm imagining) for folks to write new generic functions, due to many type constructors...
On the other hand, the complexity is there, even if you don't write it down!
It would be a big project, and a worthy effort, to write down types for everything in SICM.

Data science in Scala
You can use https://github.com/scalanlp/breeze. A Scala library that's sorta a numpy/plotting equivalent. Unlike Spark which covers more use cases than just the classic Data Science workflow, Breeze is built specifically for "Data Science in Scala". The drawback is a classic one in Scala land where some major libraries abruptly get abandoned. Breeze's commits seem to have slowed down significantly and their website on their github page www.scalanlp.org is broken.
