The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

I'm learning c++ at work the last few months, and I'm considering asking to do AoC during work - what prep could I do for AoC in c++?
The fiddliest part is processing the input into usable form. I ended up with a template which used regex to convert a file of similar lines into a vector of tuples. It's not amazing code, I'm sure, but it did the job: https://github.com/UnicycleBloke/aoc2021/blob/master/utils/utils.h, used for example here in the run() function: https://github.com/UnicycleBloke/aoc2021/blob/master/day13/day13.cpp. Share and enjoy. ;)

[DAY 6] C# solution with commentary
I'm not certain, but this seems similar to my solution: https://github.com/UnicycleBloke/aoc2021/blob/master/day06/day06.cpp. I rotate an array of counts for days, and add the count for Day 8 to that for Day 6. Speed depends on the machine, but both parts run in about a millisecond on mine.

Anyone using c++'s standard libraries for AOC?
My code isn't amazing or anything, but it is here: https://github.com/UnicycleBloke/aoc2021

C++ https://github.com/UnicycleBloke/aoc2021/blob/master/day03/day03.cpp. I suspect I'm overdoing the template-y goodness, but it's a learning exercise. Made such a meal of Part 2...

Nice. I figured we'll be parsing lines a lot so have written a function to parse the input into a vector of tuples: https://github.com/UnicycleBloke/aoc2021/blob/master/day02/day02.cpp.

Here's the relevant extract from my (recursive) solution. Full code on GitHub.

Like others, I used lcm. Here's an extract of the solution, omitting parsing and main(). Full solution on GitHub.

Solutions to parts 1 and 2 nearly identical and pretty much worked first time. Nothing clever here. This was far simpler than I thought it would be. I probably spent most time trying to think of a mathematical way of getting all points between p1 and p2. In the end, I just constructed two ranges. Full code here.

The core of my solution below using numpy (because I'm learning it!). See github for full code.

Python 3 solution using numpy. I got held up because I assume (but know better) that numpy arrays are [x,y] instead of [row, col], which is [y,x].

Below is the new solution, which works for part 1 and 2. The full code is on GitHub.

These are the key functions. The whole code is on GitHub

Part 2 (extract shown below) was a matter of starting with the low points found in part 1 then recursively looking around for relevant points. Full code on GitHub
