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.

Very ugly, very hardcoded, very dirty, and a really quick C# solution. Will clean up it in the next couple of days.

C# solution, this day is the day when my code for the first part returns the correct value for the second part! Secret is that I didn't read that I need numbers of dots after the first fold and I did print results out of curiosity. But it works!

Bare minimum atw-style K interpreter for learning purposes
I recommend checking BQN at https://mlochbaum.github.io/BQN/ and the YouTube channel code_report by Conor Hoekstra (and also "Composition Intuition by Conor Hoekstra | Lambda Days 2023"). It is well documented.

YAML Parser for Dyalog APL
I don't put a lot of stock in the "write-only" accusation. I think it's mostly used by those who don't know APL because, first, it's clever, and second, they can't read the code. However, if I remember I implemented something in J 10 years ago, I will definitely dig out the code because that's the fastest way by far for me to remember how it works.
This project specifically looks to be done in a flat array style similar to Co-dfns[0]. It's not a very common way to use APL. However, I've maintained an array-based compiler [1] for several years, and don't find that reading is a particular difficulty. Debugging is significantly easier than a scalar compiler, because the computation works on arrays drawn from the entire source code, and it's easy to inspect these and figure out what doesn't match expectations. I wrote most of [2] using a more traditional compiler architecture and it's easier to write and extend but feels about the same for reading and small tweaks. See also my review [3] of the denser compiler and precursor Co-dfns.
As for being read by others, short snippets are definitely fine. Taking some from the last week or so in the APL Farm, {β΅Γ·β¨+/|-/Β―9 Β―11+.β?2β΅2β΄0} and {(βΈβ£Β―1+\βIO,βΊ)β[βIO]β΅} seemed to be easily understood. Forum links at [4]; the APL Orchard is viewable without signup and tends to have a lot of code discussion. There are APL codebases with many programmers, but they tend to be very verbose with long names. Something like the YAML parser here with no comments and single-letter names would be hard to get into. I can recognize, say, that cβΏΒ¨β¨β(β¨ββ§β¨βUβ)β(~β’βLFβͺWSβ¨)Β¨c trims leading and trailing whitespace from each string in a few seconds, but in other places there are a lot of magic numbers so I get the "what" but not the "why". Eh, as I look over it things are starting to make sense, could probably get through this in an hour or so. But a lot of APLers don't have experience with the patterns used here.

Uiua: A minimal stack-based, array-based language
> Are there any other languages that use glyphs so heavily?
APL (the first, invented in the 1960s): https://en.wikipedia.org/wiki/APL_(programming_language)
BQN (a modern APL, looks like an inspiration for Uiua though I don't know): https://mlochbaum.github.io/BQN/
Too many smaller esoteric languages to count.

Is there a programming language that will blow my mind?
Vouch for array programming, but also BQN. Modern, very good documentation, a bit less confusing than APL imo.

K: We need to talk about group
Thereβs also at least BQN, which I suspect is the language used in those comments:
- APL: An Array Oriented Programming Language (2018)
- Show HN: Glidesort, a new stable sort in Rust up to ~4x faster for random data
-

Well, a former Dyalog APL developer did go on to create his own language based on ideas from APL called BQN, which is touted as "an APL for your flying saucer"

I spent the last 2 months converting APL primitives into executable NumPy
The latest APL-INSPIRED and in my opinion, best array language, is BQN: https://github.com/mlochbaum/BQN
