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.

-π- 2021 Day 6 Solutions -π-
Yeah, I should've expected part 2 to have a ridiculous amount of fish... I went with a HashMap for saving how many fishes were at ages 0-8 each day. These are my favourite types of exercises, simple code and the solution is not immediately apparent. Cleanest code yet! GitHub

Thought today's solution looked pretty clean. Regex for parsing the input, a HashMap for saving overlaps and a simple .scan() for generating the points.

Advent of Code day 12 advise
I was having a hard time figuring out day 12 of Advent of Code. In the end I gave up and went looking for some solutions. I came across this one and this one. However, I didn't quite understand what they did.

F# solution in Jupyter Notebook. Got some help from this thread.

-π- 2021 Day 20 Solutions -π-
F# solution in Jupyter Notebook. Part 1 takes 500ms but Part 2 takes 24s. Any suggestions on where performance could be improved would be appreciated!

-π- 2021 Day 18 Solutions -π-
F# solution in Jupyter Notebook. Thank God for the Haskell programmers! I would not have been able to solve this without peeking at their some of their code. Parsing the input string was just the first of the challenges! I envy those dynamic programming languages with an eval function.

F# solution with Jupyter Notebook. Brute force. I actually solved Part 2 before solving Part 1, unknowingly.

-π- 2021 Day 16 Solutions -π-
F# with Jupyter Notebook. Learned how to use recursive types today! Half-way through the problem I was starting to wonder whether BITS was going to be the new IntCode.

[2021 Day 15 (Part 1 & 2)][F#] Why is my implementation of Dijkstraβs Algorithm so slow?
So this year I'm learning F# and functional programming. I could not figure out a immutable solution. So I went with an imperative, mutable solution and did pretty much a straight port from Red Blob Games including using a PriorityQueue.

F# with Jupyter Notebook.

-π- 2021 Day 12 Solutions -π-
F# with Jupyter Notebook. Slow but works. I'll probably come back to this day and optimize the solution.

-π- 2021 Day 11 Solutions -π-
F# in Jupyter Notebook. Decided to go with an infinite sequence (generator pattern) for the steps. This made Part 2 a breeze!
