I have seen a couple of snarky comments about how AoC is just a competition for who can write an input parser the fastest for 25 days in a row, I'll just share the following:
Just write that once, put it in a template /day0 folder that has /day0/part1, /day0/part2, and /day0/input.txt, and then just copy it and focus on the actual problem. It's all about having fun!
I just rely on Apple's iCloud contacts, you can add people into groups if you just want to see subsets of them, and it's enough. Sometimes simple is good.
Just saw some screenshots of a Discord conversation where a supposed friend/collaborator of the maintainer denied it, instead confirming it was a cease and desist.
Take both this and the top comment with many grains of salt.
Got mild tinnitus in 2016 after an ear infection, and for about 1 year I was really bummed out about it. Then I guess I learnt to ignore it and sort of "forgot" about it. Now if I am reminded about it (thank you :) ), I can 'concentrate' on it and realise it's still there in some capacity, but otherwise I go on about my day no problem and don't think about it.
