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.

Data diffs: Algorithms for explaining what changed in a dataset (2022)
At Latacora, we use a giant pile of Clojure (almost everything, with specific measured exceptions, is). As a side effect, we have a lot of data. Not necessarily a lot in the sense of "big S3 bill", but definitely a lot in the sense of "you might not expect this being in a machine-readable format".
Things like: what Lambdas existed in a customer AWS account 6 months ago in us-east-2 that had access to a specific SQS queue (because we learned later that one of the consumers of that queue would actually consume Python pickles if you asked nicely, and hence get you RCE).
As a side effect, we do a lot of data diffing: just mostly on more vanilla Clojure structures rather than data sets in the Datasette/CSV/... sense.
For example: https://github.com/latacora/recidiffist (which we also have wired up to Terraform + S3, so if you write some files to S3, you can get the structured diffs right next to it for free). It's one of those things that's incredibly simple and works ridiculously well. Well, if you do it consistently anyway.
Also https://github.com/lambdaisland/deep-diff2 for when we're more interested in presenting it to humans.

Data diffs: Algorithms for explaining what changed in a dataset (2022)
some years ago when I was digging into DIFF and Macrobase (the one from Ballis lab) I made a simple reproduction of DIFF algo https://github.com/PiotrZakrzewski/macrobase-diff
What are some alternatives?
