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.

[Hobby Scuffles] Week of December 5, 2022
I have started doing this years Advent of Code in BQN, which is an APL-inspired Array programming language. It's been wild how different I have to think about stuff in BQN compared to something like Rust. Also the solutions tend to look absurd to the untrained eye E.g. this is the my solution for day 1 after parsing the data: ((0⊑⍒)⊑⊢)+´¨ .

How to Combine Multiple Set Operations, i.e. take the Union of 3 sets?
While an experienced programmer, I'm just starting to learn Rust by doing this year's Advent of Code in it. For today's problem Day 03 , I needed to find the intersection of three sets of characters. Using HashSet, I'd expected to be able to do something along the lines of this:

While you are correct about the stdlib, check out swift-algorithms (https://github.com/apple/swift-algorithms). It's written by Apple and has several interesting methods.

Do you use algorithms in Swift?
We used Swift Algorithms once or twice. It just depends on the app. I suggest starting with the WWDC video.
