Advent of code is an coding advent calendar where a new puzzle is released every day for people to solve
The numbers there (apart from the timer) in the site that was linked can be clicked to bring you to specific puzzles (1 aka Day 1 for the puzzle on the 1st of december, 2 aka Day 2 for the 2nd of december, etc.)
Weve got a go community in the site that you might get some answers from rather than the general community here [email protected]
This is more a community for the development side being activitypub instead of fediverse
Theres communities like [email protected] though
I haven't touched friendica much so dont know the answer to that
Ended up misreading the instructions due to trying to go fast. Built up a system to compare hand values like its poker before I realized its not poker
Likely last day im going to be able to write code for due to exams coming up

top left of the site in the navbar, and for sites who collect all of the different instances such as join-lemmy and lemmyverse. Also shows up in things like error pages in the new frontend
Smaller in the navbar but in the cases of join-lemmy and the things like error pages its larger (you can see the size by going to https://join-lemmy.org/instances?topic=all_topics&language=all&scroll=true)
Uses typescript but can be used for both js and ts, I make bots in Javascript using it
[JavaScript] Relatively easy one today
Part 1
function part1(input) {
const split = input.split("\n");
const times = split[0].match(/\d+/g).map((x) => parseInt(x));
const distances = split[1].match(/\d+/g).map((x) => parseInt(x));
let sum = 0;
for (let i = 0; i < times.length; i++) {
const time = times[i];
const recordDistance = distances[i];
let count = 0;
for (let j = 0; j < time; j++) {
const timePressed = j;
const remainingTime = time - j;
const travelledDistance = timePressed * remainingTime;
if (travelledDistance > recordDistance) {
count++;
}
}
if (sum == 0) {
sum = count;
} else {
sum = sum * count;
}
}
return sum;
}
Part 2
function part2(input) {
const split = input.split("\n");
const time = parseInt(split[0].split(":")[1].replace(/\s/g, ""));
const recordDistance = parseInt(split[1].split(":")[1].replace(/\s/g, ""));
let count = 0;
for (let j = 0; j < time; j++) {
const timePressed = j;
const remainingTime = time - j;
const travelledDistance = timePressed * remainingTime;

count++;
}
}

Was a bit late with posting the solution thread and solving this since I ended up napping until 2am, if anyone notices theres no solution thread and its after the leaderboard has been filled (can check from the stats page if 100 people are done) feel free to start one up (I just copy paste the text in each of them)
Ill be submitting some logos and another banner that im making in gimp later in the week
Edit: exams are pain, will do that before the end of the month
Starting off banner submissions with a quick banner generated from midjourney
Example view of it in lemmy explorer
Turns out I got really lucky and my location value is much lower than most peoples which is why it can be solved relatively quickly

Saw the author tooting about this project on Mastodon and I wanted to share it with everyone here.
Weβve all been there. You get to the end of a game jam and realise you need to set up an Itch page asap, or youβre wrapping up a long term project and youβre too burnt out to have the energy to even think.
This is a template pack that aims to take that pesky thinking out of the process. Just follow the template dimensions for the various images on your Itch page, and thatβs one less thing to worry about and one more thing helping you stand out from all those unloved pages out there.
