[real hinge]

it will be pure pain

[steady fog]

it looks fun

[proper totem]

do try assembly

[real hinge]

it looks fun when you are not doing it

after trying and not even figuring out how to read a file

[steady fog]

@real hinge

[real hinge]

you will suffer

[proper totem]

it is also fun when you're doing it :3

[hazy sinew]

override fun solvePart2(input: File): Any { val l = input.rl().map { it.substringAfter(": ").split(" | ").map { s -> s.split(" ").filterNot { it.isBlank() } } }; val cards = List(input.rl().size) { 1 }.toMutableList(); for (i in l.indices) { val matches = (l[i][0].size + l[i][1].size) - l[i][0].union(l[i][1]).size; for (j in 1..matches) { if (i + j >= cards.size) continue; cards[i + j] += cards[i] } }; return cards.sum() }

happy now?

[teal mountain]

assembly without c stdlib

[hazy sinew]

that doesnt count tho

[glacial abyss]

uwu

[real hinge]

yes

[proper totem]

I did that for day 2 aside from printf to print the solutions at the end but even that is relatively simple to replace

[steady fog]

@real hinge hi

[teal mountain]

dang

[real hinge]

hi

[steady fog]

@real hinge did you do part 2

[real hinge]

yes

[teal mountain]

i had an assembly course earlier this year, was a surprising amount of fun

[steady fog]

I'll do part 2 tomorrow

[real hinge]

nop

DO NOW

[steady fog]

but I'm in bed

[teal mountain]

did this among other stuff https://github.com/aetheryx/a9-game

[real hinge]

get out

[steady fog]

never

[proper totem]

it is definitely a lot of fun yeah, i really like how you have to think about things different

[teal mountain]

this just uses sprintf and the c bindings for raylib obviously (but i had to / those would replace the mode 13h interrupt without c interop)

[real hinge]

is printing in assembly even that hard

[steady fog]

I love risc

[proper totem]

dang, that's definitely more complex than anything I've done in asm

[harsh marsh]

sorry for missing your ping i locked myself out of my dorm and it took half an hour to get back in

[real hinge]

how did you get back in

[hazy sinew]

override fun solvePart2(input: File) = MutableList(input.rl().size) { 1 }.also { cards -> input.rl().map { it.substringAfter(": ").split(" | ").map { s -> s.split(" ").filterNot { it.isBlank() } } }.forEachIndexed { i, l -> (l[0].size + l[1].size - l[0].union(l[1]).size).let { matches -> (1..matches).filter { i + it < cards.size }.forEach { cards[i + it] += cards[i] } } } }.sum()

done

[real hinge]

insanee

[harsh marsh]

maybe your intersect relies on the inputs being sorted?

[real hinge]

but also isnt .let .also kinda cheating

[teal mountain]

its just a single interrupt (for each char) iirc, it's a pain but it's not that hard all things considered

[harsh marsh]

oh

[steady fog]

that is it

[harsh marsh]

you figured it out

[hazy sinew]

nahh

otherwise its gonna be insanely impractical

[real hinge]

you literally get one extrra line

python people somehow do without those

I wonder if theres single one that done today in single line

[steady fog]

now make it as fast as possible

[harsh marsh]

with walrus operators you can do most things in python single line

[hazy sinew]

it already runs in 8ms in kotlin

chill

[steady fog]

FASTER

you need microseconds

@real hinge I should make kotlin compiler plugin

[hazy sinew]

no ty

[real hinge]

doubt

it seems powerful but you dont really get one extra line

[real hinge]

do

[steady fog]

okay

[harsh marsh]

i mean do you count comprehension with walrus assignment as one line or not

because if you do you can do basically anything

[steady fog]

@real hinge is a walrus

[hazy sinew]

i think this is the shortest it can get
override fun solvePart2(input: File) = MutableList(input.rl().size) { 1 }.apply { input.rl().map { it.substringAfter(": ").split(" | ").map { s -> s.split(" ").filterNot { it.isBlank() } } }.forEachIndexed { i, l -> (1..l[0].intersect(l[1].toSet()).size).filter { i + it < size }.forEach { this[i + it] += this[i] } } }.sum()

[real hinge]

I can make it shorter with python

[steady fog]

you can remove spaces

also

in filterNot you can use a function reference

[real hinge]

print("Part 1: 18519, Part 2: 11787590")

one line

[harsh marsh]

sum((m:=len(set((s:=l.split())[2:12])&set(s[13:])))and 1<<(m-1)for l in open(0)) part 1 is pretty straightforward

[steady fog]

what lang

[harsh marsh]

python

[teal mountain]

what the hell

[harsh marsh]

comprehensions + walrus 😄

[solemn python]

I haven't done python in ages but I do remember how amazing list comprehension was

[harsh marsh]

i miss list/dictionary comprehension so much when coding in js/ts

Object.fromEntries(Object.entries(obj).map(([k,v]) => [k, v])) just is just so gross

compared to {k: v for k, v in d.items()}

[teal mountain]

list comprehensions are just [].map right?

mapping objects sucks though yeah

[harsh marsh]

map and filter combined

and efficiently because you only do one pass

[teal mountain]

ah

[harsh marsh]

[<expr> for <var> in <iter> if <expr>]

and they turn into generators

with lazy evaluation

[hazy sinew]

override fun solvePart1(input: File) = input.rl().map { it.substringAfter(": ").split(" | ").map { it.split(" ").filterNot { it.isBlank() } } }.sumOf { 2.pow(it[0].intersect(it[1].toSet()).size) / 2 }

[harsh marsh]

how about part 2?

[hazy sinew]

here

[proper totem]

look at what was taken from us https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Deprecated_and_obsolete_features#legacy_generator_and_iterator

[tranquil vapor]

it already had

[real hinge]

Why do you know

So bad

I was suprized to see cargo existed

Thought it was preinstalled

[tranquil vapor]

aoc sweats are insane

[tranquil vapor]

cause i installed it...

[steady fog]

@tranquil vapor

sleepp

[real hinge]

WHY

Ven is unsaveable

[tranquil vapor]

i just woke up stupit

[real hinge]

Sleep again

You dirty r*st user

[tranquil vapor]

I DONT USE RUST

rini and fawn held me at gunpoint forcing me to install rust

[delicate crane]

Vee, Are we getting a leaderboard for aoc

[tranquil vapor]

wdym

it's pinned here

[delicate crane]

Like a channel

There was one last year

[tranquil vapor]

uh

I can bring it back but this being a thread makes it hard

[delicate crane]

Ah

[tranquil vapor]

cause where would I put the channel

[delicate crane]

Someone smarter than me can find a good solution

[hazy sinew]

i this english

[delicate crane]

That sentence tripped me up hard when reading it

[real hinge]

Poor venny

[tranquil vapor]

i think it's saying

card 1 has five winning numbers. and it has eight numbers that you have

[harsh marsh]

@hazy sinew this is the best I could do in python sum(d.append(((t:=sum(c for c,x in d if i<x)+1),1+i+len(set((s:=l.split())[2:12])&set(s[13:]))))or t for d in([],)for i,l in enumerate(open(0)))

actually my strategy here probably sucks

144 bytes hmm

for d in([],) is cheating really hard

or it should be for d in[[]]

[hazy sinew]

oh yeah

wait what i thought my numbers were on the left

bruh

i mean its irrelevant

but if i did it with a loop i wouldve failed

[tranquil vapor]

i love how i already solved 3 days in ruby yet my repo still has more rust even though i used rust only for one single day last year

[hazy sinew]

i was wondering why the winning numbers were more than my numbers

was that day 17

[tranquil vapor]

https://codeberg.org/Ven/AdventOfCode/src/branch/main/2022/day11/src/main.rs

[hazy sinew]

i wouldnt know

[hazy sinew]

mines even longer https://github.com/eagely/adventofcode/blob/main/src/main/kotlin/solutions/y2022/Day11.kt

i wasnt very good at kotlin or puzzles when i did that

[native pewter]

yeah i did one day in zig, all 4 in julia

[hazy sinew]

16 for loops just for day 11

lmao

16 if checks

[native pewter]

monkeyactivity

[hazy sinew]

i remember day 11 took me like a week to solve

and i gave up after that till november

[tranquil vapor]

wtf

[hazy sinew]

i was moduloing by different numbers for a while afaik

[tranquil vapor]

i forgot / lost motivation after day 11

[real hinge]

For me that is swift

[tranquil vapor]

my swift solution was very compact

https://codeberg.org/Ven/AdventOfCode/src/branch/main/2022/day9/solution.swift

[hazy sinew]

day 15 with kotlin is a lucky roll

python day 14 is very unlucky

[glacial abyss]

advent of call of duty

[hazy sinew]

why tf 24 in php

[tranquil vapor]

oh the remaining languages were in no paticular order

[hazy sinew]

did u just pick the best one for the day

[real hinge]

I did swift on day14

[real hinge]

After say 7-8 it becomes insane

Last year I needed to do path finding algorithm

Gave up immediatly

[high lintel]

same

[hazy sinew]

if its path finding its an easy day

[high lintel]

the wording today confused me so much

[hazy sinew]

the hard days are the unique ones

like day 17

or day 18

or day 20

or day 21

[real hinge]

I gave up after doing 14

Idk those

[hazy sinew]

or day 22 (its pathfinding but you have to fold a cube)

the rest are easy

[tranquil vapor]

@real hinge remember when you wrote a C++ solution and forgot to initialise array so it was using random bytes

and you got a different solution each time u ran

[native pewter]

lmao

[hazy sinew]

i hope theres a lot of puzzles like day 12 this year

[real hinge]

Yeah

I was going insane

[hazy sinew]

just a standard bfs

[real hinge]

Everytime I run I get different answer

I think you found the problem somehow

[native pewter]

i mean impressive it worked at all

[real hinge]

With weird gcc args

Lmao

[tranquil vapor]

when even address sanitiser can't help

I wonder why not

since you're technically reading random memory

i think i didnt initialise my array either but I always wrote before reading so it didn't cause problems

yeah lmaoo https://codeberg.org/Ven/AdventOfCode/src/branch/main/2022/day10/solution.cc#L11

[daring marlin]

**solution.cc: **Line 11

char crt[6][40];

[real hinge]

Probably

[real hinge]

The funny thing is

Adding another uninitialized array to top of it was fixing the problem

[tranquil vapor]

HAHAHAH

[real hinge]

That was what driving me insane

[tranquil vapor]

[hazy sinew]

c++ moment

[sullen fiber]

?!?!?!

WHEN DID THEY DO THIS

WHY

IN FAVOR OF WHAT

[tranquil vapor]

Am i getting this right?? lookaheads with quantifiers in regex are deprecated?

[proper totem]

that seems like it'd be a correct interpretation

[proper totem]

yes, it's terrible

it's be amazing if js had list comprehensions

es 7 where did you go wrong

[native pewter]

Object.__parent__ ?????

[tranquil vapor]

fire

need that back

[native pewter]

what the hell is this... https://developer.mozilla.org.cach3.com/en-US/docs/Archive/Web/Sharp_variables_in_JavaScript#document-main

is that pointers in js...

[proper totem]

yummy circular references

object.parent function.caller and the comprehensions I think are the biggest losses

especially the comprehensions

[real hinge]

Are those Firefox only or globally

Also wasnt javascript backwards compatible

Do they remove features

[harsh marsh]

the # means something different now

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes/Private_properties

[tranquil vapor]

yes

but only if removing them has small impact

there are many deprecated features that are still used heavily so they won't remove them

vencord uses multiple deprecated features

[real hinge]

var is also depraced for long time right

[tranquil vapor]

no

[real hinge]

How

I thought it was replaced with let

[harsh marsh]

let has way more sensible semantics but iirc there are occasional times when you want things to be hoisted to fix module circular dependency issues

also like transpiler/minifier pipelines only output var so almost every page uses it extensively in their bundle

let/const are still mostly seen on dev side instead of in browser runtime

im behind a day now and day 3 is kicking my ass

😭

[tranquil vapor]

is there a way to fetch the example?

like this

but for the example instead of input

i dont wanna have to scrape

basically https://adventofcode.com/2023/day/4/example

[native pewter]

i doubt, since sometimes its different examples

[tranquil vapor]

i just want to automate the boilerplate creation >.<

[harsh marsh]

the examples are always in a pre > code

so if you can parse HTML you can get it

the python aocd helper package has it implemented

i don't really use it though lol

the format changes sometimes and its hard to fetch the answers though

https://github.com/wimglenn/advent-of-code-data/blob/main/aocd/examples.py

[tranquil vapor]

god part 2 description is horrible

so confusing

ruby is so fucking goofy i swear

normal languages: arr.includes(thing)
fucking ruby: arr.include? thing

[harsh marsh]

is ruby popular still

my only experience with it is using it for aoc once years ago

the stupid 2016 day 5 https://adventofcode.com/2016/day/5 where its braindead if your programming language has md5sum built in and a pita if it doesn't

2015 and 2016 had a few that required md5sum but the maker stays away from that kinda standard library check these days

[tranquil vapor]

ayy done

[hazy sinew]

no normal language has includes everthing uses contains

[tranquil vapor]

https://codeberg.org/Ven/AdventOfCode/src/branch/main/2023/day4/solution.rb#L18-L19

[daring marlin]

[tranquil vapor]

i love rubys syntax

funny

nop

[hazy sinew]

why is it the absolute value of n

[tranquil vapor]

thesre are so easy

24 lines of code for both parts...

[hazy sinew]

2 lines for both parts 😼😼😼

[tranquil vapor]

ok nerd

[real hinge]

As you do in all problems "regex"

[hazy sinew]

https://github.com/eagely/adventofcode/blob/main/src/main/kotlin/solutions/y2023/Day4.kt

[tranquil vapor]

File.foreach(file).with_index do |line, idx|
end

this syntax is kinda cursed

File.foreach(file).with_index

its cool tho

[real hinge]

Ven add ventracker here when

[tranquil vapor]

it attaches indexes to the iterator

[hazy sinew]

its similar in kotlin

File.forEachIndexed { file -> /* stuff */ }
or
File.forEachIndexed { it.doStuff() }

or for (i in File.readLines().withIndex())

[tranquil vapor]

yeah but

.foreach().with_index

[real hinge]

include_str!("input.txt").to_string().lines().for_each( |らさあ | {stuff})

@tranquil vapor WHY HUSK

[tranquil vapor]

[high lintel]

#aoc-leaderboard when

[real hinge]

I can no longer use a language that doesnt have unwrap

[high lintel]

why to_string

[real hinge]

I am addicted to unwrap

I want to use unwrap everywhere

[real hinge]

I dont remember

[high lintel]

(unwrap is actually bad and you shouldn't use it in a real program)

[solemn python]

I love .enunerate(), very useful for rust iterators

[solemn python]

nO

[high lintel]

yop

[solemn python]

Do not fall to the dark side

Unwrap is great for AoC but literally nowhere else

[real hinge]

I was sitting today

And said

What if I unwrapped myself

Wouldnt it be unwrapping cool

[solemn python]

Sounds painful

[real hinge]

Whats the alternative tho

[solemn python]

actual error handling?

[real hinge]

Guh but everything returns option

Even though I know its not null

[solemn python]

But it could be

[real hinge]

If some electromagnetic rays striked my computer yes

[solemn python]

Rust has results and options to try and force you to error handle everything

Obviously some of those are never going to happen in your situation

[real hinge]

Also dont you have to use unwrap eitherway

After checking option.is_none

[solemn python]

But it's still better to have at least an error message that isn't a panic unwind

[solemn python]

Match blocks

Or if let

Or let Some(_) = ... else {}

[real hinge]

Can you use option in match

Didnt know that

[solemn python]

Of course you can

Its an enum

Any enum can be used

[real hinge]

Yeah but it returns "Some"

[solemn python]

It returns Option::Some(T)

An enum variant with one field

[real hinge]

Yes

[solemn python]

And match blocks let you extract the fields inside of enums

[real hinge]

Dont you need to unpsck it again

Oh

Okay good

[solemn python]

love automod

But yeah match patterns are very flexible it's pretty cool

There are so many safe ways to unwrap a result or option

That aren't ".unwrap() and hope it doesn't panic"

[harsh marsh]

have you seen Gleam before

[real hinge]

Now I am even more confused why rusher hates golang

Yeah you dont do if err every second but you do something similar to it

[tranquil vapor]

HOP OFF ALIUCORD

SO BAD

[real hinge]

Die

[solemn python]

Never

@real hinge help me get rust set up

[real hinge]

Write cargo init

single file

[real hinge]

Idk if that is possible

[steady fog]

wrong

its working now

@real hinge ```rust

println!("{}", m);

}

[real hinge]

you wrote your first unwrap

congrats

[steady fog]

i will unwrap you

@real hinge i got a bunch of days ready

C++, Rust, Julia, JS

reading the file, running it works

@real hinge i did part 2 from last night

soon I will go full microsoft on my phone

[native pewter]

@sullen fiber when you gonna do aoc in malbolge

[native pewter]

id panic too if i got an empty box :(

[proper totem]

assembly users when I call printf (terminated by signal SIGSEGV (Address boundary error))

[native pewter]

how are you doing asm btw? through c?

[proper totem]

I use gcc to link the binary and one function from the c standard library to print the results but otherwise it's all just raw assembly

my entire build process

[native pewter]

damn even file reading?

[proper totem]

I cheat and embed the input into the executable

[native pewter]

ah thats true

[tranquil vapor]

qhar

what's that even supposed to mean

false

ruby is very fun to use

[proper totem]

ruby kinda nice it's just a little weird sometimes

would rather use ruby than python

[tranquil vapor]

yeah

ruby more like cozy

they're not comparable

but it's obviously
typescript > ruby > kotlin > java > rust

[native pewter]

so true

[native pewter]

try julia :3 (im gonna keep shilling because its actually kinda nice)

[tranquil vapor]

isn't julia jvm based or smth

or am i thinking of smth else

[native pewter]

no,,,

[tranquil vapor]

do aoc in groovy

[native pewter]

oh i didnt know this but its actually compiled with llvm

[tranquil vapor]

:/ sry im not gonna touch a programming language for straights

[native pewter]

oh wow https://github.com/JuliaInterop/JavaCall.jl

[tranquil vapor]

julia looks cool

i will use

but tomorrow is crystal meth day so can't use julia

[native pewter]

multiple dispatch is so cool

maybe ill watch their talk on it later

[native pewter]

wdym

oh crystal?

oh sure ill do tomorrow :3

[tranquil vapor]

yeah I'll try crystal tmrw

[delicate crane]

Did you ever find a good way to fetch example and example output?

[tranquil vapor]

no

you would need to scrape it probably

i checked and the examples don't have any html classes unfortunately

[real hinge]

oh my god you guys are so lazy

import requests
import bs4


text = requests.get('https://adventofcode.com/2023/day/4')

soup = bs4.BeautifulSoup(text.text, 'html.parser')

for i,code in enumerate(soup.select("body > main > article > pre > code")):
    with open(f"example-{i}.txt","w") as file:
        file.write(code.text)

there

[solemn python]

I looked at it and I am going to try

[real hinge]

tho for part2 you need to provide headers

[solemn python]

I think the best method is finding all code > em

[delicate crane]

I am pretty close

[solemn python]

Then taking the last if there are multiple

[real hinge]

I AM ALREADY DONE IT

GUYS

[solemn python]

I don't see why the answer wouldn't be the last one on the page

[delicate crane]

const examples = articles.map((index, article) => doc(article).find('pre > code').first().text())
const exampleAnswers = articles.map((index, article) => doc(article).find('p > code > em').last().text())

[solemn python]

Doesn't that not work day 4

[real hinge]

IT DOES

[solemn python]

The answers

Not the example text

Is what I meant

[real hinge]

how would you even get answers

[solemn python]

code > em

Take last

That works for days 1-4 at least

[real hinge]

would that be reliable

[real hinge]

fair

[solemn python]

I don't see why the answer wouldn't be the last one on the page

Day 4 has a bunch of emphasized code blocks but they all lead up to the final one which is the answer

[delicate crane]

can someone find any examples where any of the following assumptions isn't true

1. there are 1 or 2 articles on the page, corresponding to the text for part one and two
2. the contents of the first pre > code in each article is the example input for that part
3. the contents of the last p > code > em in each article is the example output for that part

[native pewter]

why would you bother scraping the output

you need to put it in your specific lang file anyways

or are you guys doing a single language 🙄

[delicate crane]

no?

[delicate crane]

yes

[real hinge]

https://adventofcode.com/2022/day/15

actually nvm

yeah it works

[delicate crane]

I haven't solved that one, so I don't have it's part two

but part one I got
15.ex.json

{
  "partOne": {
    "input": "Sensor at x=2, y=18: closest beacon is at x=-2, y=15\nSensor at x=9, y=16: closest beacon is at x=10, y=16\nSensor at x=13, y=2: closest beacon is at x=15, y=3\nSensor at x=12, y=14: closest beacon is at x=10, y=16\nSensor at x=10, y=20: closest beacon is at x=10, y=16\nSensor at x=14, y=17: closest beacon is at x=10, y=16\nSensor at x=8, y=7: closest beacon is at x=2, y=10\nSensor at x=2, y=0: closest beacon is at x=2, y=10\nSensor at x=0, y=11: closest beacon is at x=2, y=10\nSensor at x=20, y=14: closest beacon is at x=25, y=17\nSensor at x=17, y=20: closest beacon is at x=21, y=22\nSensor at x=16, y=7: closest beacon is at x=15, y=3\nSensor at x=14, y=3: closest beacon is at x=15, y=3\nSensor at x=20, y=1: closest beacon is at x=15, y=3",

}

[native pewter]

oh

[real hinge]

I would rather it to use real new linestbh

.split("\\n")

[delicate crane]

pretty sure .split("\n") would work fine

[real hinge]

yes it would but

eeeeeeeeeeeeeeeeeeeeh

I would rather be able to do string.lines()

[tranquil vapor]

i will split mantika

[delicate crane]

what kinda language has string.lines()?

[real hinge]

rust

[delicate crane]

if string.lines() doesn't work on a string with \n newlines, then that is string.lines() problem

[real hinge]

I think it would recognize \n as \\n

[delicate crane]

how

[warped dust]

manti are you braindead

JSON

[delicate crane]

because it literally contains \n not \\n

[warped dust]

ITS JSON

JSON ESCAPES

THEY GET PARSED

[real hinge]

oh does it

okay then

[warped dust]

BRAINDEAD

[real hinge]

well yes but in regular text files \n gets converted into \\n

[warped dust]

NO

[delicate crane]

r7 76 gmftfuyghkjjhuigjk,lg vkl,fy6ky

[native pewter]

are you being stupit on purpose

[solemn python]

Just added example scraping and a command to view it

Now just to use it to test stuff automatically

[real hinge]

Whar

On json yes it indeed converts \n into newline

But doesnt on regular file

Void broke my heart by calling me stupit

[native pewter]

you have "\n" in the file not '\n'

[real hinge]

Whar

[native pewter]

whatever

[real hinge]

Whats the difference

[native pewter]

" is a 2 len string and ' is a char

[real hinge]

Doesnt matter on python

[native pewter]

youre missing the point

i give up

[real hinge]

Horr

Anyway I eep

Night night

Windows 10

[native pewter]

gn!

i will put w11 while youre asleep

[solemn python]

beautiful

[warped dust]

most fuckin stupid aoc setup

you need to read the problem

[delicate crane]

we do read the problem

its just a very quick way to check if our answers are correct against a free test case

[warped dust]

takes two seconds to copy paste it

[solemn python]

it was just because I can, im never going to actually use that to look at the input lol

[delicate crane]

thats two seconds

[solemn python]

ill probably delete that subcommand soon, I was just bored lol and wanted it to be fancy

[tranquil vapor]

someone should get ai to summarise the AOC assignments

cause got damn those are some essays

aint reading allat 😭

[solemn python]

so true

[tranquil vapor]

am i the only one who skips the first few paragraphs

[solemn python]

I try to read it but inevitably end up skipping it

[tranquil vapor]

i appreciate the effort the creator put in but at the same time i kinda just want the exercise

[warped dust]

i start reading the last few paragraphs and then go up

[tranquil vapor]

shit reminds me of math class

[solemn python]

10pm isn't too late for me but still my brain is not comprehending that stuff when I just want to solve the puzzle and go to bed

[warped dust]

im pretty sure the reason they're making the prompts insane now is to distrupt ai

[solemn python]

good

[tranquil vapor]

ai gonna be waffling about gondolas instead of solving the problem

[warped dust]

real

[tranquil vapor]

i hate ai so much

[warped dust]

wtf is a gondola

[tranquil vapor]

ruining everything

[warped dust]

https://tenor.com/view/gondal-caterpillar-bug-insect-crawling-gif-16267445

[tranquil vapor]

girlie...

https://en.wikipedia.org/wiki/Gondola

[warped dust]

YOU CALL THESE GONDOLAS??

[tranquil vapor]

YEAH

WHAT ELSE BITCH

if you're gonna say canoe or smth I will eat your liver

[warped dust]

gondola LIFT

[tranquil vapor]

can i get an uber

[warped dust]

this shit https://en.wikipedia.org/wiki/Gondola_lift

[tranquil vapor]

LOL

among us??

[warped dust]

we call them teleféricos

i thought in enligsh its just cable car

[solemn python]

I did not know a gondola was a boat

all I knew was the lift

[warped dust]

the direct translation is telpher apparently

brb lemme get on this telpher

who up telphering

[solemn python]

she telpher on my gondola till i

[delicate crane]

Currently it only updates xx.ex.json when the start script is ran. But once I integrate a submission bind, it will automatically update it when I successfully submit part 1

[delicate crane]

I have added race mode to my script.
It waits until the next day unlocks, and immediately

1. opens the problem in the browser
2. creates and opens a file to create the solution in
3. downloads the input
4. parses the problem page to get a test input/output for part one

[warped dust]

loser

[native pewter]

lmao

[warped dust]

who actually cares about doing it fast

u suck

[native pewter]

be nice bitch

[warped dust]

fucking have fun with things

[delicate crane]

I care about doing it fast because my brain is highly suseptible to wanting to maximize meaningless internet points

[solemn python]

I'd like to do it fast but I'm never going to be zoomy enough to get any significant reward from it so who cares

If I do make fancy setup stuff it's for convenience or because I'm bored, not because I actually care about speed

[native pewter]

id love to compete but what is that time man its horrible

my ass is not coding at 6am

[solemn python]

Just get a better timezone

It's 10pm for me

[proper totem]

8pm

[delicate crane]

Advent of code favors people outside america

[warped dust]

yes americans are the only people with conflicting timezones

[proper totem]

timezones in red are disadvantaged due to sleep and timezones in orange are disadvantaged due to traditional work hours

ironically the US/Canada still has a lot of advantage all things considered

[harsh marsh]

west coast US is particularly good

east coast is fine for me, 12 am is my normal brain active hours

and doesn't conflict with school, work or clubs

[sullen fiber]

WTF IS THIS

NOT A GONDOLA FAKE FAKE FAKE

[sullen fiber]

YES

FAKE FAN

Can't believe you're not immersed

@warped dust rate my day 4

[steady fog]

delete that

i beg of you

fear my data structures

[steady fog]

so

[real hinge]

Cant code

[steady fog]

can

[real hinge]

Unneccesaryli painful

I would rather wait until I get my pc

Anyway it looks like we just need to convert numbers to each other billion times

@real hinge boo

[real hinge]

I dont think you are supposed to do that

[solemn python]

part 1 done

[proper totem]

part two is meaaaaaan

[real hinge]

Part2 will never get finished

[proper totem]

best rank i think i've ever gotten

[sullen fiber]

oh god

part two

the naive method is obviously not gonna work

i dont wanna do this in uiua

this might be where i start doing them in typescript

yea ts it is

[real hinge]

why does vps not have glibc

[sullen fiber]

they prob have musl

[steady fog]

garlic powder

[real hinge]

horror

STILL SAME ERROR

oh my god

it requires libgc 29

BUT DNF DOESNT HAVE THAT

it has 28

how did it end up like that

[harsh marsh]

whew I am a clown

how did I make so many mistakes doing that

[solemn python]

I'm gonna do it

For the memes

You can't stop me

Hehhehehehehhe

Rust go brrrrrrr

[sullen fiber]

fak

e

[proper totem]

I know there's probably a better way to do it

but

[solemn python]

It's going rn

[proper totem]

oh well! I am alright with my six minute solution

[solemn python]

73% of seed group 2

[harsh marsh]

ur insane

[sullen fiber]

explode

[solemn python]

I know

This is literally a crypto miner and it's hilarious

Wonder how long it'll take

[harsh marsh]

I know there's this one package I used once for dealing with range overlaps quickly

probably should have spent the timing remembering what that package instead of doing it manually

[solemn python]

Aaaaand finished

the power of rust knows no bounds

[sullen fiber]

JESUS CRIST

[harsh marsh]

oh damn it worked

im surprised the input wasn't big enough to rule out brute force solutions

[sullen fiber]

rust too powerful

[solemn python]

my largest range was 811,833,837

and overall it checked 2,549,759,327 seeds

[sullen fiber]

i wish typescript had range type

im so sad

[hazy sinew]

bro can topaz stop trying to throw off llms and make the early days easier

22 minutes for top 100 is too long for day 5

[steady fog]

optimize this

[solemn python]

I will eventually

I want to figure out the real solution not the dumb one at some point

[hazy sinew]

i tried doing that in kotlin, it didnt even finish the first range after 15 minutes

but i think the real solution is a oneliner

[solemn python]

Well yeah I don't think you are going to get very far on anything that doesn't use native executables

[hazy sinew]

i think my only chance of getting global is if its a late day and i already have a utils function for the solution

maybe like day 18

of 2022

with a 3d grid and u have to count something

ppl will be implementing 3d arrays from scratch and still getting global

[hazy sinew]

bro said

[proper totem]

my js solution did it in 6.5 minutes

[solemn python]

Every single number???

[proper totem]

yop

[solemn python]

Guess I'm just bad

No clue how but guess I am

[proper totem]

it could be we have wildly different numbers of seeds

[solemn python]

True

[proper totem]

you can see how long my input takes with your stuff if you want

[steady fog]

ok so

make aoc in a bootable efi

@proper totem

have fun

[proper totem]

that would be cool! unfortunately: i have finals next week and don't have time to make asm aoc solutions for two weeks ;w;

[steady fog]

one day I will do

low level coding is so cool

[proper totem]

could do a bootloader instead

er

I guess you need the larger numbers from 32 bit protected mode

so efi would be easier yea

[solemn python]

You seem to have a little over half my seeds

And I'm not waiting for it to finish so idk who cares, I got the solution

[proper totem]

makes sense

a little over half would put our solutions at roughly the same speed then maybe

[solemn python]

Is your computer decent

[proper totem]

pretty decent yeah

newer laptop

[solemn python]

Mines a pretty generic Lenovo laptop from years ago

Anyways I should sleep

[steady fog]

same

goodnight tyminky

[sullen fiber]

AAAAAAAAA

part 2 is wrong

[delicate crane]

my shit keeps stopping randomly before it finishes

[sullen fiber]

i th ink my math is right but

[delicate crane]

no errors

[sullen fiber]

fake

TF

virus

[delicate crane]

it just fucking stops

literally says OK im tired now

and dies

[solemn python]

Is it OOM'd?

[delicate crane]

no, it would say OOM if it was OOM

[solemn python]

idk

[delicate crane]

I fixed my OOM error by chunking seeds into arrays of 65536 size

[solemn python]

I just never generate the list of seeds but ok

Iterators are my friend

But no clue why yours would just die that makes 0 sense

[delicate crane]

yea

I increased my chunking size and it made it further, its still going

range 3/10 16%

[solemn python]

Glad to see at least 2 others followed me to the dark side

[delicate crane]

dark side?

[solemn python]

This horrible solution of brute forcing it

[delicate crane]

I can't think of anything better

[sullen fiber]

WHY DOES MY CODE WORK ON EXMA_PLE

BUT GIVES WRONG NUMBER ON UINPUT

I WILL KILL EVERYONE

[solemn python]

I can think of a way I just didn't feel like it

I'll solve it correctly eventually

[proper totem]

we will use multithreading

this is definitely the intended solution

[solemn python]

That too

[delicate crane]

I would, but I hate threading in js

[sullen fiber]

wait

i had the right answer the whole time

WTF DID I SUBMIT

?!#@$r%tyr^u&%#$r

that is so stupid

typescript so good

assembly level speed

[proper totem]

i will inspect how the speedy solution is supposed to work

[solemn python]

I have a plan that I might try tomorrow

[proper totem]

🔍 👁️

[delicate crane]

mine was 111,184,803

[proper totem]

oh that speedy solution makes sense i guess

[delicate crane]

where is the speedy solution?

[proper totem]

vap's repo

it kinda bothers me that the speedy solution is one that doesn't feel elegant at all

it makes sense why it works and how but it doesn't feel nice, at least to me

[sullen fiber]

ngl i think its only unelegant because ||ts/js doesnt have range as a stdlib type||

||it would prob be good in a langauge there is a nice range type, idk any tho||

[delicate crane]

It took my js 23.3 minutes to brute-force it

[sullen fiber]

||toMap in Mapping::mapRange would easily just be range.intersect(source), and before / after would be a disjoint range.subtract(source)||

[harsh marsh]

I didn't know there were languages with that in their stdlib

my python solution gets 50.6 ms for part 2 but theres a lot of inefficiency

got it down to 2.47 ms by adding a couple of break statements

[real hinge]

wait

wth is the second part

need a nasa computer

oh my god

I need to remake my entire solution

I was storing them in arrays and do entire step at once

[real hinge]

I ran out of battery

this will take forever

[proper totem]

are you printing progress on every seed

if you are then most of your processing time is probably taken up by i/o and not actually calculating the solution

[real hinge]

Every 100000

[proper totem]

o

i wasn't sure because of the 33 at the end

[teal mountain]

this years aoc SUCKS

why are we getting optimization problems so early already

i started a bruteforce but it finished (10 mins or so) before i was done with the optimized version

i did eventually get it though https://github.com/aetheryx/aoc/blob/main/src/2023/day5/index.ts

@warped dust uiua might actually be bad for my brain

i spent like a minute wondering how tf to reshape an array in ts

[warped dust]

uiua brainrot

[hazy sinew]

this is almost 1 line (if i use .let and .also everywhere and inline seeds and mapping)

[sullen fiber]

YOU KNOW WHAT

||the mappings are bijective, i will just binary search the maps backwards for uiua||

[hazy sinew]

instead of val result = hashMapOf<LongRange, Boolean>()
hashMapOf<LongRange, Boolean>().let { result ->
everything else
}

[native pewter]

🤨

[sullen fiber]

its so good

js needs reshape

its so perfect and good and holy

[warped dust]

.flat().chunks(5)

[sullen fiber]

FR

NEED

it doesnt even need to be multidimensional really

if i could do it all 2D it woudl eb eoucpic

[warped dust]

deshapes vap

deshaping for real

dumping your elements onto the stack

directly

[sullen fiber]

[/id]

wait

[warped dust]

WTF

[sullen fiber]

no the oppisite

/id

[warped dust]

inv

[sullen fiber]

i think

reduce alr operates on an array idk why i rearrayed it

[warped dust]

/id takes 0 arrays

[sullen fiber]

thats getting deprecated

not / but like dumping onto the stack arbitrarily

also inv -> un

and unbox -> un box

[warped dust]

unbox deprecated ??

[sullen fiber]

true

they say stuff like that

and im like "!?!?!? in favor of what???

and theyre like oh sike its being renamed

[warped dust]

uiua devs on fuckinb crack

[sullen fiber]

i need some of that

the uiua site is all in rust

its kinda wacky

[warped dust]

wrong

theyre hiding the js

websys tries so hard

[sullen fiber]

it looks cool but, there was like no debug information in the errors 😭

[warped dust]

making you write the worrst js

[sullen fiber]

dude it looked so bad esp making callback closures

[warped dust]

because youre awkwardly using generated bindings for each call

so baad

[warped dust]

probbly trimmed

[sullen fiber]

.unwrap().dyn_into::<ArrayBuffer>().unwrap()

I wonder how low I can go if I multithread

but doing mt in rust is

[sullen fiber]

people using spoilers like they're censoring a govt document is kinda funny to read

[real hinge]

@sullen fiber what is this

[sullen fiber]

part 1 in uiua

[real hinge]

wth is that

[sullen fiber]

stack oriented array language

[real hinge]

[sullen fiber]

https://www.uiua.org/

i wanna think of a way to do part 2 easy so bad

ok copilot

[tranquil vapor]

WHAT IS THAT

[warped dust]

copilot writing your emotions for you

[sullen fiber]

@warped dust uiua bytecode is actualyl really cool

stuff like fork both bracket gets inlined

and temporal execution limit is built into the interpreter

also shout out to NumProcs

[warped dust]

not as COOL as THe BEAM

[solemn python]

https://github.com/piman51277/AdventOfCode/blob/master/solutions/2023/5/part2.cu GPU accelerated brute forcing

[real hinge]

what the

[sullen fiber]

ISJNANE

INSANE

[solemn python]

I was curious so I went on the reddit thread

[real hinge]

wait is fast solution || just mapping the ranges instead of 600 million numbers ||

[sullen fiber]

||yea thats what i did||

[real hinge]

makes sense

[sullen fiber]

||the pain is that a single mapping can split one range into 3 at most||

[real hinge]

but that would probably take me more than 2 minutes to implement

[sullen fiber]

teru

true

[real hinge]

yeah that can be horror

holy shit

[sullen fiber]

||yea i was gonna linear search the reverse map but i was scared of how long it'd take in uiua||

||lemme actually try it rq||

[solemn python]

I'm surprised how many people went brute force on this one

[real hinge]

it is the easiest one ig

|| both reverse scanning and range matching is a bit horror||

[solemn python]

It's funny but also they could have just made the numbers a few digits bigger and this problem would have been solved

[real hinge]

||tho reverse search would probably be easy to implement (but also I think thats a gamble too if they made smallest number something like 18284718 it would take forever again) ||

@tranquil vapor your solution soon

[solemn python]

@real hinge do you love

[real hinge]

if I could understand it

there is a chance

wth is that

that isnt rust

[warped dust]

its rust

welcome to macros

what the hell

I am never looking at aoc subreddit again

even devilbro cant get this worse

Someone visualized their input

[sullen fiber]

i was doing the same thing

imma not do that anymore cus it sucked

thats so sick

aoc hash function

i was gonna do it in desmos instead of svg but svg is a lot saner

[tranquil vapor]

WTF

[sullen fiber]

@solemn python can i tell you a way to optimize your bruteforce, i wanna see how fast it runs in rust

[real hinge]

MINE RUNS IN RUST TOO

but I am lazy watever

[tranquil vapor]

okk aoc timee

[sullen fiber]

oh wow urs was fast for a normal bruteforce wtf

[tranquil vapor]

CRYSTAL IS SO BAD

[sullen fiber]

maybe i'll try my optimization idea on urs and see if it makes it fast

[real hinge]

do

[solemn python]

I don't really have any time until tonight but sure I could try

When I have time

[sullen fiber]

no worries no worries imma try it on manti's
