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.

On DataFrame datatype in Ruby (2016)
Me neither! Don't know how or why it suddenly appeared on the HN main :)
Just to provide a bit of the personal context: this article caused creator of DaRu (Sameer Deshmukh) to contact me and propose to work on DaRu together, and so I did (see @zverok here: https://github.com/SciRuby/daru/graphs/contributors). I also was, for some time, SciRuby/DaRu's mentor for Google Summer of Code (and, IIRC, it was my initial idea that daru-view grew from).
Also, since that article, an independent dataframe library https://github.com/ankane/rover was created by Andrew Kane, handling some of API and implementation in a cleaner way.
That being said, I am not sure that DaRu, or Rover (or "dataframe" idea in general) has enough visibility in the Ruby community. It is mostly thought as "some special scientific thing", while I believe in 2021 it should be seen as one of the necessary everyday high-level datatypes.
That's what I'd focus this article on if I'd written it today.
Ruby Units
-
Database structure for storing data received in multiple different possible units, that supports interchangeability.
I'm not an expert on the industry standards, but why do you have to store the conversion unit? Can't you just use a library like https://github.com/olbrich/ruby-units to do the conversions?
