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.

Haskell adoption is higher than I expected, what can we do to get it to top 10 languages.
Don't get me wrong, we figured it all out, and currently we use Aeson fork as we needed this: https://github.com/haskell/aeson/pull/926, as the default behaviour didn't work with Swift, and I wasn't sure if it's worth spending any time completing it...

How to implement a disk cache plugin for Elixir's Req HTTP client?
> no error checking at all (I assume it just panics or exception?)
In Elixir, bang functions per convention will raise on error. `get/2` will return error tuples allowing you to handle errors. In fact, get!/2 just calls get/2 and raises for you[^1].
> no mention of JSON at all
Req is the most "batteries included" Elixir HTTP lib out there. I can't speak for Wojtek, but I believe the goal was to make Req extremely easy to use in scripting or things like LiveBook without having to do much work. That being said, the automatic decoding is mentioned in the readme[^2] and the docs[^3].
> if "body" is JSON, how do you even get the raw body, or can you?
Per the docs[^3], you can either skip with a `:raw` option, or just build your own request using only the steps you want.
> just seems over engineered/over fitted whatever you want to call it.
Fair, but again, this library is designed to be on that end of the spectrum. There are plenty of other libraries further down the stack that you can use. I am partial to Finch[^4], upon which Req is built.
To address the sibling comment about "Let it Crash", the language allows you to easily recover from crashes, but that is for resiliency, not error handling. In practice you would use the non-bang get/2, pattern match on the response, handle any errors, perhaps use Kernel.get_in/2 to safely traverse the map, etc. The example provided by the author is not "production ready".
