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.

The yaml document from hell
I used the official reference implementation to make a CLI converter between NestedText and TOML, JSON, and YAML. When generating one of these formats, you can use yamlpath queries to concisely but explicitly apply supported types to data elements.

The YAML Document from Hell
I'm a huge fan of NestedText, especially as there is no escaping needed ever.
If you ever want to use it as a pre-format to generate either TOML, JSON, or YAML, I used the official reference implementation to make a CLI converter between them and NestedText.
When generating one of these formats, you can use yamlpath queries to concisely but explicitly apply supported types to data elements.

A practical issue with YAML: your schema is not documentation
In case you're interested and haven't seen it, I've become a big fan of NestedText, which is similar to YAML but without the complicated parts, and without types (just strings, lists, and dicts). The idea is that any meaningful validation and coercion belongs in code anyway. An extra cool part is that nothing ever needs to be escaped, so the content is super clean and unambiguous.
If you want to play around with it, I made NestedTextTo (nt2 on PyPI), for CLI conversion between NestedText and YAML, TOML, or JSON, with a pretty cool (IMO) way to cast value types along the way.

How do you yaml
I recently fell in love with the NestedText format, and whipped up a CLI for conversions between it and YAML (and JSON and TOML), so now whenever manually viewing those other formats I pipe it through into readable NestedText. In this example, the result is identical to format A.

nt2: a CLI converter between NestedText and JSON, YAML, or TOML
So I made nt2 (NestedTextTo) (install from PyPI as nt2[toml] for TOML support).

Advent of Code Day 4
My best suggestion here would be clj-kondo with flycheck-clj-kondo in Emacs. I really can't recommend it enough and would have killed to have it when I was learning Clojure. Not only will it underline all of those references to (now) undefined vars, but it can tell you about numerous little mistakes like mixing up arguments orders in (say) sequence functions, misplaced docstrings that get discarded, style conventions, etc. It's staggering how good it is even for a language as dynamic as Clojure.

The Joy of Static Analysis: automated Clojure code refactoring
Clj-kondo doesn't produce an AST but you could easily combine the analysis output with the AST produced by rewrite-clj by matching on location.

Can you use Clojure for mobile, backend, frontend, scripts, desktop, and embedded development?
But if you want full support, you can implement a hook: https://github.com/clj-kondo/clj-kondo/blob/master/doc/hooks.md

Wrote one of my first clojure programs (tic-tac-toe). Any constructive criticism would be greatly appreciated.
Please configure and use tools like clj-kondo and kibit. Kibit will report areas where you could write idiomatic clojure instead. Eg, it should catch all those (if (condition) true false) and ask you to replace it with (condition). Or if you really need a boolean value, use boolean to coerce it.

Are these problems something that Just Make Sense once I learn more, or what?
Try clj-kondo, a Clojure linter which will tell you about arity errors and more, before you even evaluate your code.
