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.

From First Principles: Why Scala?
The call stack is "magic" built into the language, so as soon as you're not using the "blessed" way of error handling, you lose it and need to rebuild the same functionality "by hand".
I agree that some kind of logical call stack is a very useful thing to have, and I'd recommend implementing something along the lines of https://github.com/lancewalton/treelog that provides it.

From First Principles: Why Scala?
After a number of years with Python, I started a position working in Scala about 6 months ago. I really wanted to learn something new, and become acquainted with functional programming concepts.
I agree with most of the above. A couple of additional thoughts:
sbt -- I still have a lot of coming up to speed to do here, but the manual is like 500 pages and it's somewhat overwhelming. There are tons of little oddities, like why can't I run `sbt --version` and instead have to do `sbt sbtVersion`?
The functional side is fascinating -- I'm still studying the cats library. I can almost describe a Monad! It's a pretty big mountain, though, and there are times where I have doubts whether the benefits will be worth it. Would love to hear some re-assurance! ;)
The ecosystem for microservices seems pretty closely tied to akka & lagom. These are quite complex in their own right and we've been having trouble with the latter in particular. Curious to learn about alternatives. ZIO?
Re: DSLs. Also not a huge fan of DSLs. One refreshing thing about python is that often configuration can just be in Python itself (as in Django, for example). See also:
