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.

[2021] [Nim] Nim is Beautiful + All days in < 130ms
This year I was writing two sets of solutions in Nim. The first one focuses on idiomatic, nice and short and readable Nim. The other focuses purely on speed. The combined running times of the fast solutions is 130 ms. Please let me know if you have any tips on how to make my solutions more simple and/or idiomatic.

Day 6 Proof of Correctness
Note also that you can solve this without a complexity dependency on n. Most solutions I have seen, including mine run in time O(tD), where t is the maximum value of a timer, and D the number of generation, requiring O(t) memory. (This is assuming we can do the required arithmetic operations in constant time, and each numbers require a fixed around of memory storage; if the number of fish gets huge, throw in an additional log n in the complexities, where n is the number of fish on the final day).

How do I read today's input ? Part 1
In my Perl solution of today (I assume, you mean 2021, Day 4), I read stuff in paragraph mode ($/ = "") which makes Perl split input on 2 or more newlines.

2021 Day #4 (Part 1) [Native Python ONLY] - Conceptual Guidance?
I considered doing that for my (Perl) solution, but given the cards are small, that seemed overkill.
