Santa needs YOU to save christmas
Advent of Code is an annual coding competition/event with daily challenges. Even complete beginners can keep up for the first few days as the difficulty slowly ramps up.
Join the rDrama leaderboard and see how you compare to your fellow dramanauts with the following code:
632268-20c7d1d5
Enter it here https://adventofcode.com/2022/leaderboard/private
tech/science swag. 
On-Topic: Anything that good slackers would find interesting. That includes more than /g/ memes and slacking off. If you had to reduce it to a sentence, the answer might be: anything that gratifies one's intellectual laziness.
Off-Topic: Most stories about politics, or crime, or sports, unless they're evidence of some interesting new phenomenon. Videos of pratfalls or disasters, or cute animal pictures. If they'd cover it on TV news, it's probably lame.
Help keep this hole healthy by keeping drama and non-drama balanced. If you see too much drama, post something that isn't dramatic. If there isn't enough drama and this hole has become too boring, POST DRAMA!
Please do things to make titles stand out, like using uppercase or exclamation points, or saying how great an article is. It should be explicit in submitting something that you think it's important.
Please don't submit the original source. If the article is behind a paywall, just post the text. If a video is behind a paywall, post a magnet link. Fuck journos.
Please don't ruin the hole with chudposts. It isn't funny and doesn't belong here. THEY WILL BE MOVED TO /H/CHUDRAMA
If the title includes the name of the site, please leave that in, because our users are too stupid to know the difference between a url and a search query.
If you submit a video or pdf, please don't warn us by appending [video] or [pdf] to the title. That would be r-slurred. We're not using text-based browsers. We know what videos and pdfs are.
Make sure the title contains a gratuitous number or number + adjective. Good clickbait titles are like "Top 10 Ways to do X" or "Don't do these 4 things if you want X"
Otherwise editorialize. Please don't use the original title, unless it is gay or r-slurred, or you're shits all fucked up.
If you're going to post old news (at least 1 year old), please flair it so we can mock you for living under a rock, or don't and we'll mock you anyway.
Please don't post on SN to ask or tell us something. Send it to [email protected] instead.
If your post doesn't get enough traction, try to delete and repost it.
Please don't use SN primarily for promotion. It's ok to post your own stuff occasionally, but the primary use of the site should be for curiosity. If you want to astroturf or advertise, post on news.ycombinator.com instead.
Please solicit upvotes, comments, and submissions. Users are stupid and need to reminded to vote and interact. Thanks for the gold, kind stranger, upvotes to the left.
Be snarky. Don't be kind. Have fun banter; don't be a dork. Please don't use big words like "fulminate". Please sneed at the rest of the community.
Comments should get more enlightened and centrist, not less, as a topic gets more divisive.
If disagreeing, please reply to the argument and call them names. "1 + 1 is 2, not 3" can be improved to "1 + 1 is 3, not 2, mathfaggot"
Please respond to the weakest plausible strawman of what someone says, not a stronger one that's harder to make fun of. Assume that they are bad faith actors.
Eschew jailbait. Paedophiles will be thrown in a wood chipper, as pertained by sitewide rules.
Please post shallow dismissals, especially of other people's work. All press is good press.
Please use Slacker News for political or ideological battle. It tramples weak ideologies.
Please comment on whether someone read an article. If you don't read the article, you are a cute twink.
Please pick the most provocative thing in an article or post to complain about in the thread. Don't nitpick stupid crap.
Please don't be an unfunny chud. Nobody cares about your opinion of X Unrelated Topic in Y Unrelated Thread. If you're the type of loser that belongs on /h/chudrama, we may exile you.
Sockpuppet accounts are encouraged, but please don't farm dramakarma.
Please use uppercase for emphasis.
Please post deranged conspiracy theories about astroturfing, shilling, bots, brigading, foreign agents and the like. It degrades discussion and is usually mistaken. If you're worried about abuse, email [email protected] and dang will add you to their spam list.
Please don't complain that a submission is inappropriate. If a story is spam or off-topic, report it and our moderators will probably do nothing about it. Feed egregious comments by replying instead of flagging them like a pussy. Remember: If you flag, you're a cute twink.
Please don't complain about tangential annoyances—things like article or website formats, name collisions, or back-button breakage. That's too boring, even for HN users.
Please seethe about how your posts don't get enough upvotes.
Please don't post comments saying that rdrama is turning into ruqqus. It's a nazi dogwhistle, as old as the hills.
We reserve the right to exile you for whatever reason we want, even for no reason at all! We also reserve the right to change the guidelines at any time, so be sure to real them at least once a month. We also reserve the right to ignore enforcement of the guidelines at the discretion of the janitorial staff. Be funny, or at least compelling, and pretty much anything legal is welcome provided it's on-topic, and even then.
Do not use outdated operating systems that are unsupported to access SN. What are you, poor?

But I only know python

Python's actually not a bad choice, honestly. Pretty fast to write. I did AoC in C for the lulz a couple years back and got on the global leaderboard a few days, but most normal people do more concise languages like Python or esoteric codegolfing langs.

what is it with those? like half

these are like... either brainfrick tier languages or "implement this very specific thing in 1 character"

The latter of those are basically optimized specifically for AoC, haha.

I solved the first two puzzles and I still don't know how the stars work.. Is that a puzzle too?
Jump in the discussion.
No email address required.
if you complete the first task on a day you get a silver star for it
if you complete both tasks on a day you get a gold star instead

I got 2 gold stars but leader board says 76?

if you are the first person to get a certain star, you get points equal to the total players in the leaderboard. if you are the second person to get it, you get 1 less point, etc

ahh got it now, so thats the leader board score. confused me for a while

python is a fantastic choice because youre never judged on the speed of execution. tangentially (and still in benefit of python), standardizing how you choose to do data ingest/sanitization/output formatting is braindead easy in python - being able to plop the problem data into a "data.txt" and just "data = open('data.txt', 'r').readlines()" is a lot better than most other languages. python has fantastic useability for string manipulation and typecasting, and its incredibly fast to write and iterate on (you write pseudocode and it Just Werks™). i prefer some of javascripts array methods, but then the file handling and io boilerplate is lacking (also node_modules lmao). just give it a try.

javascript also can't add numbers with decimal points without an add-on library (or a bunch of unnecessary inline arithmetic like multiplying and then dividing all your numbers by 1000 or some stupid bullshit). Like every other r-slurred thing about the language, they can't ever fix it because all javascript functionality has to be backwards compatible to 1995 forever.

This is r-slurred. Js uses double as its base numeric type, like 99.99% of other languages. Integer arithmetic is supported up to ~2^53, because doubles. The strategy used in many other languages to support precise decimal arithmetic is to have a separate decimal type, which js could also do without any backwards compat issues.
not even necessary tbh. If your numbers map to physical quantities, simply change the unit of the physical quantity from U to mU or uU or nU. Walla, you have extreme precision. Since your prior choice of units was already arbitrary, this one isn't any worse.

I just use an add-on library (decimal.js) if I'm doing calculations on the frontend. I've read the articles on why decimal math doesn't work in js and I can't be bothered to write a bunch of dumb shit in my code like the geniuses on stack overflow who will do this kind of crap every time they want to write a math statement:
Sure though, adjusting your units to only be whole numbers is also fine.
Despite there being a solid reason, as you stated, for math not working out of the box in js, having not provided any solution built into the language for the last 25+ years is kind of fricking stupid, if you ask me.
Edit: even this stack overflow crap I've pasted in here doesn't actually work, btw. It "works" if you know the precision of your inputs is no more than 3 decimal places, and if you're certain the "extra" result of the innermost calculation is truly insignificant (since floor is just erasing information). What if you actually need to round some numbers in here? There are so many edge case failures with this kind of shitty kludge.

True, but in javascript, you don't need to load the file at all, you can just reference the input as document.body.innerText. You can code your solution in the browser developer tools without even leaving the site. It's the true lazy man's approach.
