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.

Advent of Code 2022
AoC is one of my favorite events of the year! I find the puzzles generally approachable, but interesting enough to spend time on. I also like that there's a definitively right answer, which motivates me in an interesting way. I've developed a base class over the years that handles input parsing, so I can focus more on the solutions themselves.
Additionally I've been solving for a number of years, but for the past 2 years, I've done a daily explanation of the solution. I use interesting parts of the Python stdlib and walk readers through common algorithms. I've found it _incredibly_ rewarding and plan on doing it again this year.
You can see all of those solutions here: https://github.com/xavdid/advent-of-code/tree/main/solutions
Please let me know if you enjoy reading these, I love hearing from folks!

Nice! This was basically the same as my solution, but mine was much more verbose.

Day 1 Part 2 Issues
I do a daily solution walkthrough on GitHub if you'd like to follow along. Yesterday's is here: https://github.com/xavdid/advent-of-code/blob/main/solutions/2021/day_1

Advent of Code 2021
AoC is one of my favorite events of the year. I find the puzzles to be much more approachable than things like Project Euler. I regularly credit my yearly participation for making me a better programmer.
I also do a daily writeup of my solution, which helps make sure I understand the problem and help others who are learning. I found it super rewarding last year, so I'm doing it again this year. They're in my GH repo. Here's today's: https://github.com/xavdid/advent-of-code/tree/main/solutions...
My big tip is that you probably don't need to worry about competing for the leaderboard (unless you really want to). Go at your own pace, don't stay up weird hours, and take a break.

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.

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!
