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.

Two Years of OCaml
In virt-v2v we eventually enforced that every module file also has a corresponding interface file: https://github.com/libguestfs/virt-v2v/blob/master/check-mli...

Why and How We Retired Elm at Culture Amp
You can look at the project yourself: https://github.com/libguestfs/virt-v2v I've been writing OCaml for 20+ years and C for 40 years.

Multicore OCaml: April 2021
I develop in OCaml from time to time, and it's pretty practical. Separate compilation, makes small-ish binaries that most people wouldn't know weren't written in C/C++, easily call out to C if you need to. We steer clear of the more complex language features like functors because they confuse most programmers.
Here's an example of one very widely used production application: https://github.com/libguestfs/virt-v2v/tree/master/v2v

Traversing nested data-structures in various languages
XPath is the real killer feature for XML. I don't think it's possible to use it in this particular example, but in the more generally useful cases where you want to pull (eg) all subnodes with key matching a particular string, XPath is great.
Here's it being used in real code (search for "xpath_"):

Why your F# evangelism isn't working
If you are truly interested in understanding my point of view -- a great way to do it would be to learn how to use this Clojure DSL: https://github.com/redplanetlabs/specter

Advent of Code inside the REPL
Yes :), I needed a fast dijkstra implementation to solve a puzzle in 2021. A pure clojure implementation was too slow so i built one on top of this https://github.com/redplanetlabs/specter

Working with large maps
Don't forget about specter which is efficient and compact due to its DSL.

Nested mapping?
Learn and use specter for nested data manipulation, will take some studying but is a more general solution (https://github.com/redplanetlabs/specter)

For part 1, the version (and other things) are attached to the metadata of each sexp, and a Specter recursive path is used to extract all of the versions.
