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.

Ngn/k (free K implementation)
The author of Kona has written kerf which I believe is intended for this same space. I’ve never used it though. https://github.com/kevinlawler/kerf1

Coding in the Shadows: Hidden Gems of Lisp, Clojure, and friends
If you want to try out K, there are some open source implementations, like John Earnest's oK which has a REPL and a calculator-like interface for mobile phones with a charting feature.

Why Lisp Syntax Works
and have the programmer use the word "barchart", they instead prefer to use the definition itself. The word "barchart" has a specific meaning (here, an ascii "bar chart" of 0s and 1s, showing the relative sizes of the values of input array x), but "{x>\:!|/x}" might be useful for more than just bar charts. This idiom contains smaller idioms like "count til max" (!|/) which in turn contains "max" (|/).
Being able to see the code makes it easier to explore and tweak to your specific needs. But more importantly, there are no "official" names for concepts like "count til max". That's just my personal name for it. A python programmer would call it "range". You could come up with your own name for (!|/) that makes perfect sense to you. But that name will probably be longer than its definition, and less flexible.

Animated unknown pleasures in 3 lines of K
check out oK[0] by John Earnest, who is the author of the content of this post
it is well-written manual and is a great jumping off point
there is a k-enthusiast element.io server[1] where you can ask any question you like. folks are friendly!

kerf - Kerf (Kerf2) is a columnar tick database and time-series language for Linux/OSX/BSD/iOS/Android. It is written in C++ and natively speaks JSON and SQL. Kerf can be used for trading platforms, feedhandlers, low-latency networking, high-volume analysis of realtime and historical data, logfile processing, and more.
