[hazy sinew]

hop on kotlin

[native pewter]

im good thanks

[real hinge]

hop on java

[tranquil vapor]

I will

will you send me money if i do today in java @real hinge

[real hinge]

you asked the forbidden question to a turkish person

[native pewter]

@real hinge pay me? pretty please

[real hinge]

I am poor

not asking for money is first rule of talking with turks

[native pewter]

should i assk for rakiya then

nvm thats balkan

[real hinge]

what is rakiya

[native pewter]

i forgor muslims dont alcohol

😭

[tranquil vapor]

send me 20 cents (average monthly wage in turkey) @real hinge

[real hinge]

how do I

I can stay hungry for 2 weeks

[hazy sinew]

why is windows your personality

[real hinge]

It all started when I was 8

[hazy sinew]

when you were eight or when windows 8

[real hinge]

I

[hazy sinew]

when i was 8 i had opensuse

[real hinge]

haram

[hazy sinew]

so true

[real hinge]

opensuse is weird distro to start tbh

or actually you didnt say you started with it

[hazy sinew]

it was on my dads computer

[real hinge]

anyway using opensuse at 8 is weird

[real hinge]

increadible dad

[hazy sinew]

my first computer had ubuntu

[hazy sinew]

he still uses it

i had opensuse, ubuntu, windows 10, windows 11, ubuntu, arch

[real hinge]

I teached my dad how to use whatsapp web recently

[hazy sinew]

my dad has been programming for like 25 years

[real hinge]

thats very nice tbh

[hazy sinew]

they still use java 5 in some projects

[real hinge]

[hazy sinew]

they have java 17 projects with java 5 dependencies

i had to update some

its hell

[real hinge]

I dont get that

at least use java8

or 11

some lts version

why 5

[hazy sinew]

because dependencies that lost support at java 5

[real hinge]

arent there some new ones for java 8

[hazy sinew]

well yea but maybe some function name is different, removed, deprecated, logic changed
there is a script to update java 5 to java 8 but it doesnt always work

you have to look at a bunch of https://github.com/EnterpriseQualityCoding/FizzBuzzEnterpriseEdition type shit and figure out why theres an error

[real hinge]

hmm

considering the work

fair

[hazy sinew]

it pays decently but its SOOOO annoying

so much object converting

reading a table from a database means converting it to a badly written spaghetti class structure with a bunch of silly converter functions that are either named convert or convertToObjectname or toObjectName with capitalization differing in the same class from function to function and no naming standards, some start with uppercase, some dont, sometimes its TimeSeries, sometimes its Timeseries

its so inefficient

[tranquil vapor]

why is islam your personality

windows is better tbh at least you can run it on ur pc

[hazy sinew]

and the manager doesnt wanna switch to kotlin for new projects because it means "the team would have to learn kotlin" when theres interop and by using java they are just farming technical debt to the point where converting from a database table to a json file should be 30 seconds, but instead is 2 days

[hazy sinew]

good point

[hazy sinew]

so true

[tranquil vapor]

they should make IslamOS

i'd use it

[hazy sinew]

translate the linux kernel to arabic

[tranquil vapor]

TRUE

whats "kernel panic" in arabic

[hazy sinew]

actually rewrite it in holy c with { being inshallah and } being alhamdullilah

[tranquil vapor]

ذعر النواة

[hazy sinew]

print إن شاء الله "Hello World" الحمد لله

to solve day 2 of aoc you do
input.readLines() إن شاء الله red will be less than 13 إن شاء الله green will be less than 14 إن شاء الله blue will be less than 15 الحمد لله الحمد لله الحمد لله

someone needs to make this

[real hinge]

HALALOs

I would use too

[real hinge]

you know what they say

if its working dont touch it

[hazy sinew]

except when the client needs a new feature you have to

[real hinge]

in that case

touch as less as possible

[hazy sinew]

i would just do the projects in kotlin but actually doing the task isnt the issue, its converting the objects and kotlin might cause more compatibility issues

[real hinge]

java classes should work totally fine on kotlin

I doubt it would be problem

[hazy sinew]

they do but theres probably gonna be some incompatibility because it uses java 5 and maybe even java 1.x sometimes and i dont think kotlin supports java 1

[real hinge]

yeah that might be a problem

[hazy sinew]

lolcat unironically best linux command

hacking nasa using lolcat

[tranquil vapor]

bruhhh

i spent WAY too long on part 1

then part 2 i did in 2 minutes

i hate || 2d arrays ||

[warped dust]

rate my erlang

[tranquil vapor]

this is so terrible https://codeberg.org/Ven/AdventOfCode/src/branch/main/2023/day3/solution.rb

i cry

[warped dust]

god it was so horrible in it

[tranquil vapor]

literally just added this to my part 1 solution:

WHY SPOILER FAIL

discord markdown parser so bad

[warped dust]

https://codeberg.org/rini/aoc/src/branch/2023/day03/pt1.erl

[tranquil vapor]

discord come on

|| ```rb
banana

[warped dust]

i had to invert the way i was searching things and then do it

[warped dust]

you had an || in code

[tranquil vapor]

LOL

discord

[warped dust]

put zwsp :3

[tranquil vapor]

|| i solved part 1 by doing a nested for loop from row-1..row+1 and col-1..col+1, so basically checking the square around it. so i just added a check for "*" and then wrote to hashmap with coords as key and then in that kept track of how many nums already saw it and the sum ||

so easy

but part 1 was pain

mainly cause i was dumbbbbb

[tranquil vapor]

CHOMP

[tranquil vapor]

weird lang

[somber smelt]

what does chomp do

[warped dust]

||for each line, i made a list of the part positions and number positions with their lengths, then for each line again i filtered out numbers based on if any part on the top or bottom line was >= pos - 1 and <= pos + len||

||which for part two i was forced to invert my logic||

[warped dust]

trim trailing newline

[native pewter]

fnuy

WHY is copy ctx button lazy

im gonna

[tranquil vapor]

chomps

its rightTrim / trimEnd

[somber smelt]

oh ok

[warped dust]

no its just newline

[tranquil vapor]

cursed

[tranquil vapor]

not in ruby. it's newline(s) by default but you can pass a custom string

@split heart run ```rb
puts "banana".chomp "ana"

[split heart]

Here is your rb(3.0.1) output @tranquil vapor

ban

[tranquil vapor]

ban @warped dust

@split heart run ```rb
puts "banana".chomp "na"

[split heart]

Here is your rb(3.0.1) output @tranquil vapor

bana

[tranquil vapor]

oh it only removes first

not all

my solution does so many out of bounds array accesses

[native pewter]

[tranquil vapor]

rust fans will cry

[warped dust]

.get(i) returns Option

[solemn python]

https://github.com/TodePond/nDreamBerd ok whos solving day 4 in dreamberd

[warped dust]

[i] panics

[tranquil vapor]

so real

rini.get(12).unwrap();

[solemn python]

I used a .checked_sub(1) in my solution for day3

[tranquil vapor]

rate

[solemn python]

rini.get(12).expect("index out of bounds");
``` better

[tranquil vapor]

wait

what happens if u unwrap an Option<Option<*>>>

[solemn python]

whats the * mean

[tranquil vapor]

does it unwrap fully or only the outer one

[solemn python]

only outer

you would have to .unwrap().unwrap()

[tranquil vapor]

/run ```rs
println!("{}", Some(Some("banana")).unwrap())

[split heart]

@tranquil vapor I received rs(1.68.2) compile errors

ah yea

/run ```rs

[split heart]

Here is your rs(1.68.2) output @tranquil vapor

banana

[tranquil vapor]

funny

[native pewter]

rust so bad, cant even fmt an option

[solemn python]

rini.get(12).unwrap_or_else(|| panic!("index out of bounds"));
``` even better actually

[tranquil vapor]

terror

[tranquil vapor]

it could unwrap tbh

but ig that might be undesired

xd

but also why cant it print Options

can debug print option

/run ```rs
dbg!(Some("banana"));

[split heart]

@tranquil vapor I only received rs(1.68.2) error output

[file0.code:2] Some("banana") = Some(
    "banana",
)

[solemn python]

might be unintended to reveal the inner workings of the language in a simple print statement ¯_(ツ)_/¯

formatting a string or a number is normal, but Options/Results are rust construct

[tranquil vapor]

yeah makes sense

[solemn python]

not something someone would expect to see without deliberately trying to format it that way

[tranquil vapor]

i was gonna say it seems useful for debugging

then i remembered dbg! exists

and yeah dbg! does print option

i wish posix had a third channel
stdout
stderr
stddebug

writing debug log to stderr is kinda cursed

[solemn python]

i love evcxr

its really odd to have a repl for a compiled & statically typed language but its also so useful

[tranquil vapor]

wtf is a 0u8

and why is that not a syntax error

[solemn python]

0 + u8 = explicit type cast

[tranquil vapor]

OHH

[solemn python]

"0" defaults to i32 I believe

[tranquil vapor]

i doint like that syntax

u8(0)

better

[solemn python]

that just looks like a function

[tranquil vapor]

0 as u8

[solemn python]

thats also valid syntax though I believe that would create 0i32 and then convert it to u8

yeah

[tranquil vapor]

[harsh marsh]

lmfao

[tranquil vapor]

this is NOT clean you are a SICK PSYCHO

[solemn python]

kotlin devs have gotten a bit too adicted to extension functions

I love extension functions as much as the next person but come on

[tranquil vapor]

this is an official jetbrains repo btw

[harsh marsh]

mom can we have pipe |> syntax?
no, we have pipe syntax at home
pipe syntax at home:

[solemn python]

@tranquil vapor you love ((number.start().checked_sub(1).unwrap_or(number.start()))..=(number.end()))

[warped dust]

use {:?}

to debug print

the error message literally told you

[warped dust]

You can make classes, but you can only ever make one instance of them. This shouldn't affect how most object-oriented programmers work.

truest

[tranquil vapor]

girlie do i look like someone who reads error messages

[warped dust]

gouges your eyeballs out to eat them like lil grapes

now you wont 😊

[sullen fiber]

FEAR

[warped dust]

so goooood

[sullen fiber]

i just thought of a good solution

im giving up on that last attempt

idk what went wrong but

doing convolutions was fun

[warped dust]

soon theyll be convulsions

[native pewter]

u on de floor

[proper totem]

making large input for today could be slightly annoying

don't super want to do it maybe will do later

[tranquil vapor]

large input?

oh

could just go the lazy route and concat the normal input a bunch of times

shuffle the lines

[native pewter]

i mean you could just put random chars and make . slightly more likely

[proper totem]

there's some edge cases that need to be considered in order to be compatible with the official inputs

the input has to be a square, a gear can only have at max two parts next to it (can be less, not more)

i guess could put the input in a 2x2 square

[somber smelt]

I still haven't done todays, no idea where to go after making a matrix

[native pewter]

use a hashset

[somber smelt]

I don't see how a set is applicable

[native pewter]

||use it to keep track of what fields are adjacent to symbols||

idk how to help much more without revealing basically the entire solution

[somber smelt]

This one is straight up not fun lmao

[warped dust]

skill issue

[native pewter]

felt like it was ok

[somber smelt]

building Android is more fun

[sullen fiber]

i wanna try it

that would be more fun than actually solving this one

[native pewter]

hm can numbers be next to two symbols?

it doesnt say anything in the text but i dont think my solution would work if that was allowed

[native pewter]

are you still doing uiua

[sullen fiber]

yes.,

[native pewter]

hell

[sullen fiber]

IT WAS KINDA FUN

i made l ike

a convolution

[sullen fiber]

like htis

its actually so easy to do in uiua

[native pewter]

thats fun

[warped dust]

holy minesweeper

[sullen fiber]

WAIT TRUE AS SHIT

IM GONNA MAKE MINESWEEEPER IN UIUA

@warped dust you love that window works on any tensor so u can use it to ez convolve

[warped dust]

oh my god i needed that in erl so much

[sullen fiber]

yes but

||now i just have a bitmask for digits that are touching symbols||

||IDK HOW TO GET THE NUMBERS FOR THE DIGITS||

[warped dust]

||I did the same thing at the start, what you have to do is search for parts and then store what numbers they touch||

[sullen fiber]

||thats not exactly easier since from a matrix perspective they are really touching digits not numbers||

OH MY GOD

i know what i must do

sike

unsike

yea i know what to do

[warped dust]

||yeah what i did was store the numbers AND their lengths in digits, then do bounds check on all numbers in same and adjacent rows||

kinda want to make this in uiua now

[sullen fiber]

||i did a similar thing, where i got the coordinates of the matching digits, filtered out the ones that were touching (ones that referred to the same number) then checked if y was same and if x was within the bounds||

doing that sucked a lot tbh and also somehow didnt work for some numbers

[native pewter]

least complicated uiua program

[warped dust]

regex is prohibited

huh why is the 4th day all the way up

wtf i thougth vap already did it

vec

vec vec

what..

what do you mean list

split("\n").collect::<Vec<_>>()

[sullen fiber]

NO

[solemn python]

You could technically use an array because inputs are fixed size

[sullen fiber]

my uiua strechted my brain too much

and it hurt

i gave up

but im gonna do it fr now

cant wait to see how painful part 2 is

[warped dust]

bro actually got encephalitis

[sullen fiber]

WTF

[warped dust]

braim strech

[sullen fiber]

fake

it really was stretched tho like it felt like i was coming off of LSD or something uiua is fucked up

dont do uiua stay in schol.

[warped dust]

i dropped out to do uiua

[sullen fiber]

imma start building a uiua library

of functions that i use multiple times

in diff days

[warped dust]

the sindresorhus of uiua

[sullen fiber]

true

[warped dust]

vap really said iseven

isnumber

[sullen fiber]

sindresorhus was just trying to make javacsript more readable

truly a visionary

[warped dust]

truly https://github.com/sindresorhus/cows

[sullen fiber]

i thought it was copy on write in js

[warped dust]

nope

cows

theres even tests 😭

[native pewter]

:shiglet:

[sullen fiber]

@warped dust uiua main branch has stack

which is dumpid but as a single symbol

[warped dust]

Stack = dumpid

[sullen fiber]

LONGGGG

too long

ngl i dont really get how dumpid came first

why would u need to filter ur whole stack thru a function before debug printing

[warped dust]

e=dumpid

they should make the inverse of dump clear the printed lines

[sullen fiber]

cus u took the gondala lift up

i like that i can see the lift but its not connected cus i havent fixed it yet

[warped dust]

wait true

im forgetting aoc lore

[sullen fiber]

SMH

[sullen fiber]

I DID PART 1 @warped dust

!@#$ER%WTYGFHNB

finally omfg

that was kinda fun today

it was not fun at all last night

i should do these in the morning tbh..

uh i can explain it in a video maybe

yea not really it uses ||convolutions||

which is basically when you ||sweep across something like a grid, and change the value of a cell to something based on its surrounding values||

||i did a convolution on the grid to get 1s where digits are touching symbols, and 0s where digits arent||
||then i made another grid replacing digits with the full number value, and non-digits with 0s||
||then i multiplied the two grids together and summed the values for part 1||

omg i love part 2

[sullen fiber]

sike i only loved ||detecting the gears||

now i have to ||gear the numbers that the gears touch||

wait no im goated

[solemn python]

Minesweeper

[sullen fiber]

exac.ty

[solemn python]

I actually ||checked characters surrounding numbers, not the other way around||

[sullen fiber]

yea same

wait

||do numbers only ever get touched by 1 symbol max???||

[solemn python]

From a quick glance I think so

[sullen fiber]

wow

that opens the door to a wonderful optimization

that i will do after i do this in the dumb way

i wanna try to generate a large input with wave function collapse or smth

[sullen fiber]

@warped dust currently fighting for fill windows to be a thing

[warped dust]

HOW

[sullen fiber]

it only makes sense if the windows have an odd shape,, but

if the windows have an odd shape, then each window has a center

so fill windows (on odd shaped windows) would center the windows around each element, using the fill value as a default value beyond the edge boundaries

wanna convolve with 0s beyond the matrix? fill0windows3_3

also @warped dust @warped dust @warped dust

latest uiua has epic thing

putting ' before something will surround its whole syntax subtree ()

wait i lied he made it to something else in the release

[warped dust]

quotes you

[sullen fiber]

oh it ' splits a line and '' unsplits a line

without changing the parse tree

[warped dust]

i manually added empty lists to both ends and used the middle value of the window

trol

[sullen fiber]

yea same

thats kinda how u have to do it rn

[warped dust]

that doesnt make sense though

for fill to have this behaviour

[sullen fiber]

behold: Trim and Border
||```
Trim ← ↘1_1↘¯1_¯1
Border ← ⍜(Trim); ↯⊙: +2△.: # Takes border element and matrix

[warped dust]

but itd be cool if there was something

[sullen fiber]

true

it would be weird for fill to make windows function differently

but yea i wish there was smth

[warped dust]

pad when

[sullen fiber]

true

nice

did part 2

[steady fog]

vap will vaporize

[sullen fiber]

part2 takes like

a minute or two to run

[warped dust]

fastest uiua program

[sullen fiber]

tbh i could have done 1 kernel pass but i do 2

[warped dust]

my pt2 was like visibly slower but its still really fast

i had to make searching less efficient

we must make uiua for the beam

[sullen fiber]

||1 to mark the gears, and 1 to calc gear ratio||

[warped dust]

the BEAM

[sullen fiber]

i gotta optimize this now

[warped dust]

iwill never get tired of calling it thE BEAM

the FUkiNG BEAM

VIRTUAL PUTER

[sullen fiber]

virtal

self

[warped dust]

okay i will work on beam now

i was going to a couple hours ago but it suddenly became my mission to kill tommy tallarico

[sullen fiber]

wha r

[warped dust]

hbomberguy

actually

@eternal marlin HEY

GET YOUR ASS IN HERE

[sullen fiber]

some youtube thing

ok

[warped dust]

theres this video essay he made on the roblox sound he tries to find out who made it but it quickly goes to show how much the people in control of things bend history to attribute themselves and and

[sullen fiber]

oh interesitng

[warped dust]

its two fuckin hours long

[sullen fiber]

wt.f

large video model when

summarize thisvide please

create supercut

[warped dust]

tommy tallarico constantly lies about his achievements and it seems no one ever bothered checking them
he says hes "the first american to work on sonic", the "world record holder of person to work on most games in their lifetime", a lot of things really
and it seems each time people ask him about them even those specific things seem to get bigger (like the amount of games he's worked on, despite not working on games at all in years. and not even the first amount was marginally correct. actually he doesnt work on anything, he's just the ceo of some company (SOME companies (oh he commited crimes by lying about his company to inverstors (did i say he got a total of like 20 million dollars raised for the company, to sell a product that was never made. because he doesnt even acutally have the people to make it (yeah he lied about some big people working on the company when they actually left shortly)))))

wait fuck thats too many parenthesis already

IM SAYING ITS INSNAE

[sullen fiber]

DAyum

[warped dust]

he said he was record holder of.. 7 guinness records
when its actually 3
the other ones are because guinness had to reword their records after finding out they werent really accurate

actually hbomber himself got two of those records down by asking guinness about it, and they themselves basically said they couldnt confirm

and honestly it just goes to show how capitalism actually works

aanyway beam

[solemn python]

Out of curiosity what's your speed for part 1

[eternal marlin]

his mother is very proud

[warped dust]

oh nvm they're the same speed

[solemn python]

Mine is 94.5ms for part 1

[eternal marlin]

that was actually joey who got the records taken down 🙄🙄🙄

[warped dust]

um no

[solemn python]

118 for part2

Which is understandable considering the amount of multiplication

[eternal marlin]

no but it was actually the editor who ended up getting them taken down in the end so like close enough

[warped dust]

to be fair a lot of the time is bc im running it from escript

cuz setting up an actual erlang thing has a lot of boilerplate

[steady fog]

KILL Rini KILL

[warped dust]

m okay

i think most of the time is the node booting up

or that my cpu is 10 years old

which is still like insane cuz erl is dynamically typed and not native

rust so sloww

[steady fog]

ow

i just made a thing that deafened me

[sullen fiber]

GOOD

[proper totem]

the voices in my head got the better of me and I've started working on day 3 in asm

i have 25 minutes to finish it

[solemn python]

the difference between release and debug mode is crazy

rust moment

[warped dust]

almost like debug builds have optimisation flags turned off

two seconds is insane though

wtf

[proper totem]

simply become javascript

@solemn python you have a github repo right nvm i checked your github

[warped dust]

tyman will pacman -S erlang-nox and benchmark my scripts on their machine

[solemn python]

selfhosted forgejo

but yeah I have a repo

https://git.myriation.xyz/Ty/advent-of-code-2023

don't judge my overcomplicated setup ok

I have to spend the time waiting for puzzles doing something

[proper totem]

spooky
evidently maybe a me issue since discord scraped it fine but weird

[solemn python]

huh

are you on a network that doesn't like the domain or something

[proper totem]

oh yeah my router's isp likes to block random things let me check

[solemn python]

it is a pretty new domain so I wouldn't be surprised if I was blocked by a random ISP

[proper totem]

you hate to see it

[solemn python]

[proper totem]

oki i set up a bypass for it

[sullen fiber]

looking into generating a large input for this one

[proper totem]

you know what I will do

[sullen fiber]

and almost went down a rabbit hole of the field of constraint problems

[real hinge]

I am goijf ro school

[steady fog]

dont

[solemn python]

after this day I might setup an example testing template so its easy to copy paste in the future

[sullen fiber]

wait lmao it didnt block the message? it just removed the lines with mentions?

[solemn python]

yesterday I used tests but it was very badly formatted and setup

[real hinge]

Cant

[solemn python]

anyways see everyone after this is done

👍

[proper totem]

I was editing in the pings so I didn't ping a lot of peeps

[sullen fiber]

oh true

[warped dust]

my ass choosing the lang last minute

sikei can do it any time

[steady fog]

GO RINI GO

GOOOOO

[sullen fiber]

gs

[warped dust]

which which

[solemn python]

oh dang p1 seems easy af

[warped dust]

i will not read the thing before i choose a language

i need to choose the worst language for it

[steady fog]

GOOOOOOOOOOOOOOOOO RINI

[sullen fiber]

⛳

[warped dust]

@steady fog WHICH

[steady fog]

Do it in D lang with me

[warped dust]

vote now

[steady fog]

D lang d Lang

[warped dust]

im forbidden from doing dlang ever

fawn wont let me

[steady fog]

kill fawner

can i kill fawner

[warped dust]

okay golfscript it is

oh FUCK

[steady fog]

WHAT

[real hinge]

Todays seem easy

[steady fog]

ok i got input Now

[real hinge]

Why today is really easy compared to other days

[steady fog]

something big is coming

[warped dust]

nvm its so easy

[steady fog]

:)

[warped dust]

@sullen fiber GIVE ME A HARDER LANGUAGE

[real hinge]

Guhh aoc balance died

[sullen fiber]

LOL

[steady fog]

im having to google how to do x in dlang

[real hinge]

Do assembly

[warped dust]

FUCK YEAH

any ppc emulators

[real hinge]

Idk

[warped dust]

that would be funny

[steady fog]

@real hinge https://dlang.org/library/std/string/chomp.html

[warped dust]

FUCK X86

[steady fog]

chomp

[real hinge]

Do arm

It doesnt even have division instruction

[harsh marsh]

damn I got top 100 today (for the gold)

[warped dust]

i will do it using only intel extension instructions

shit like zbcnmksl

[real hinge]

Love

[harsh marsh]

i think that's the first ever top 100 i've gotten lol (my account goes back to 2015... although i've only done most of them for two years)

[steady fog]

insane

[sullen fiber]

not so bad

[sullen fiber]

global?

[harsh marsh]

yea

283/75

[sullen fiber]

FIRE

[harsh marsh]

part 1 took so long because i mixed up my variable names in the loop lmfao

[sullen fiber]

same but it was cus im bad at math

[harsh marsh]

i feel like it's less competitive this year than in the past?

mmm actually nvm

[solemn python]

part 2:

[sullen fiber]

this is the perfect uiua problem

cant wait to see how others did part 2

[warped dust]

I HATE ARM ASSEMBLYT

fuck it we uiua

[solemn python]

I think im just going to hashmap all the cards with their indexes & winning number counts and then analyze from there

my brain really doesn't want to conceptualize this problem lmao

[real hinge]

How bad can it be

(will see tonight)

[steady fog]

oh

[warped dust]

god bless the lines being all same length

perfect for uiua

[sullen fiber]

REAL

FUCK BOXES

[solemn python]

well part 1 of parsing shit done

now how the hell do I actually do shit with that

[sullen fiber]

FEAR

[solemn python]

aaaaaaaaa

[steady fog]

trying to figure out how to convert array of strings to ints in dlang

guh

[real hinge]

Just do manually

[steady fog]

never

[real hinge]

By charcodes

[proper totem]

fear

[harsh marsh]

https://dlang.org/library/std/conv/parse.html#1

?

[steady fog]

oh

i was trying to cast

i think

[delicate crane]

https://github.com/CodeF53/AdventOfCode/blob/main/src/2023/04.ts

[warped dust]

god pt1 was so easy on uiua

[steady fog]

rono

WHY cant i strip the string

guh

[warped dust]

CURSE OF UIUA /+≡(⌊ⁿ:2-1/+∊⊃(S↙-1)(S↘+2)⊗@|.↘+2⊗@:.)⊜∘≠@\n.&ru@\00

[solemn python]

how the hell am I supposed to debug this

[delicate crane]

_.reject(section.split(' '), _.isEmpty)
we stan lodash

[solemn python]

ok maybe a recursive function isn't the right way to do this actually

huh

[harsh marsh]

python ||py f = open("input.txt", "r").readlines() u = 0 # points c = [1] * len(f) # "c"ount of cards for i, l in enumerate(f): s = l.split() w = set(map(int, s[2:12])) # winning numbers m = set(map(int, s[13:])) # our hand k = len(w & m) for j in range(k): c[j + i + 1] += 1*c[i] if k: u += 1<<(k-1) print(u) # part 1 print(sum(c)) # part 2||

[steady fog]

virus

please use sane variable names NOW

[harsh marsh]

NO

[delicate crane]

this

[delicate crane]

you comment good variable names next to the actual variable

[harsh marsh]

lol i will start to when they get difficult >.>

the comments i just put in

was going for speed :3

you should see my day1-3 https://github.com/alchzh/advent-of-code/blob/master/2023/3/code.js

[delicate crane]

yes but you can very quickly just change names using ctrl+d

[steady fog]

f56

[solemn python]

NEVER MIND HOLY HELL

i never actually set the struct field I was supposed to set

[solemn python]

ok but for real how did I get part 2

1. without any debugging
   and 2. 2nd try

[delicate crane]

||```py
f = open("input.txt", "r").readlines()
points = 0 # points
cardCount = [1] * len(f)
for i, l in enumerate(f):
s = l.split()
winNums = set(map(int, s[2:12])) # winning numbers
handNums = set(map(int, s[13:])) # our hand
k = len(winNums & handNums)
for j in range(k):
cardCount[j + i + 1] += 1*cardCount[i]
if k:
points += 1<<(k-1)
print(points) # part 1
print(sum(cardCount)) # part 2

sane(ish) variable names for @harsh marsh's solution

[harsh marsh]

ya

though i wouldn't use camelCase in python

or map(int in any sane code

[solemn python]

I do want to improve my solution moderately because my data structures are horrible and also I may or may not have circumvented the borrow checker by cloning Vecs and Hashmaps

[delicate crane]

true, I am used to js/ts tho

[harsh marsh]

wait wait i did even int() them you can just compare the strings

[sullen fiber]

PART 2 ON UIUA

SO CRACKEd

[harsh marsh]

i think i was thinking that i might need to have the actual values for part 2 so might as well parse it right the first time

[sullen fiber]

im gonna translate my uiua into js to make a silly golf again

[solemn python]

part 2 with cloning slow af

[sullen fiber]

true my uiua is faster

[solemn python]

I'm fairly sure my current code clones a vec for every single accumulated card lmao

[delicate crane]

@rose latch open vencord server for once

[harsh marsh]

huh

[steady fog]

I CANT FIGURE OUT HOW TO PARSE STILL

fksdnjgmerkgergnergwerngberg

[harsh marsh]

D is so silly

[steady fog]

i cry

[teal mountain]

hello friends

[rose latch]

I open it

I just muted every channel except for the css channels

lmao

[solemn python]

actually you know what

I am going to leave my solution as is for now then optimise it later, but keep my old solution in a different file

as much as I don't want to retroactively change my solutions, my current code is horrible in rust terms

[teal mountain]

wtf is uiua

[warped dust]

IM SAYING

[sullen fiber]

array based language

[warped dust]

is there flatmap

something that works like it

[delicate crane]

well unmute this thread

[warped dust]

wiat

[sullen fiber]

deshape

[warped dust]

i dont need

[teal mountain]

guh

[warped dust]

wait im cracked

[sullen fiber]

also stack oriented

[warped dust]

wait im not cracked

[rose latch]

fine

[sullen fiber]

i had this matrix

and i had to stare at it for like

a good 10 minutes

to actually figure out what to do

i knew i could do it in linear time

[warped dust]

yop im trying to scan

[warped dust]

P = NP btw

[hazy sinew]

imagine not doing ||val grid = Grid.of(input.rl()); grid.filter { it.toString().matches("[^0-9.]" }.mapIndexed { p, _ -> p.getNeighbors().map { grid.numberAt(it) }.distinct()}.sum()||

[sullen fiber]

same i was trying to scan

but i actually needed to fold

cus fold lets you have ur own accumulator

[teal mountain]

based kotlin enjoyer

[solemn python]

my p1 is zoomy tho

[teal mountain]

i was contemplating doing it in kt this year but i'm trying to win on my uni lb

[hazy sinew]

so py?

[teal mountain]

typescript

[hazy sinew]

how is ts better than kt

[sullen fiber]

DAYNM

[teal mountain]

it isn't, but it's what i have more experience with

[sullen fiber]

uiua overhead got my part1 at 200ms still

[teal mountain]

i only picked up kt about 6 months ago

[steady fog]

i love kotlin

[hazy sinew]

i spent the summer making a utils lib

now anything that involves a grid in theory i should win but i keep throwing

[sullen fiber]

i wanna do this in ASM now

jk i dont wanna parse in asm

[hazy sinew]

day 4 was super easy too but it took me 14min and 16min

[teal mountain]

input parsing in c is bad enough vap

[sullen fiber]

yea. .. ,

parsing in uiua wasnt so bad today

[warped dust]

this was pt1 btw trolley

[teal mountain]

by far the easiest imo, it's the only one where i didn't run into any stupid edge cases

[sullen fiber]

oh u just floored

[hazy sinew]

cuz its early day and not weekend

[sullen fiber]

lmaoaoao

i did it a little sillierly

[hazy sinew]

tbh i shouldve placed global today

if i didnt fuck up parsing id have part 1 in 2mins

[warped dust]

whyd u partition @|

[solemn python]

They all have their own merits ok

[warped dust]

fork take drop

[solemn python]

It's not really possible to compare the two

[warped dust]

and you BOXED.

[sullen fiber]

true

had to box

HAD TO

[warped dust]

SHAME ON YOU

[hazy sinew]

in part 2 i ||did the multiplication first so in example 2 ended up going to 3 4 5 6 instead of 3 3 4 4||

[sullen fiber]

GRRR

ur right

but

i hate mixing up calc logic

[hazy sinew]

nah kotlin is objectively better

[sullen fiber]

and parse logic

[hazy sinew]

for aoc

[teal mountain]

eah same

[sullen fiber]

i have to keep my parse logic separate from my calc logic

or else i explode

[warped dust]

i lvoe writing everything in a single line and then enver remembering what i did

[steady fog]

kill rini kill rini

[teal mountain]

it's funny, i got rid of my point doubling logic from part 1 thinking i didn't need it, then for part 2 i wrote it again because i think i did need it, and then i realised i didn't

[sullen fiber]

LMAO

[hazy sinew]

took me 15 mins to figure out (total of 16 😭 )

[teal mountain]

the part 2 algo is like 5 lines of code but it took me like 8 mins to understand

the problem descriptions are kinda convoluted this year

to fight against ai/chatgpt shit i think

[sullen fiber]

writing uiua is like having a train of thought

fr

[solemn python]

How

[hazy sinew]

the winning point logic is just || substring before | .intersect substring after | ||

(as lists obviously)

[solemn python]

I mean in AoC terms a more dynamic language and a faster compiling one seems better

[hazy sinew]

have u seen the kotlin stdlib

all the data manipulation functions

u can do every day in 1 line in kotlin

[teal mountain]

my whole part 2 algo (aside from parsing)
||```ts
for (const [i, card] of cards.entries()) {
const points = card.numbers.filter(n => card.winning.has(n)).length;

for (let j = 0; j < points; j++) {
cards[i + j + 1].copies += card.copies;
}
}

return cards.reduce((a, b) => a + b.copies, 0);

and this took me 10 mins to figure out

[sullen fiber]

i think julia is like that too

stdlib is cracked

for aoc

[steady fog]

day-04-dlang.d(41): Error: no overload matches for strip(a)

??????????

[sullen fiber]

should spoiler

oh im stupoid

[teal mountain]

silly

[sullen fiber]

i clicked and forgot

[teal mountain]

what uiua does to a mf

[sullen fiber]

help

[steady fog]

wtf i dont understand

[solemn python]

By the end of AoC your brain will think only in multidimensional arrays

[hazy sinew]

i think i did
||

for(i in parsed.indices) {
    val matches = parsed[0].intersect(parsed[1]).size
    for (j in 1..matches)
        cards[i+j] += cards[i]
}

||

[steady fog]

WHY CANT I STRIP THE STRING

[solemn python]

uiua will consume your mental patterns

The voice in your head will be uiua symbols

[sullen fiber]

good

this is what i want

im genuinely hoping this helps me with thinking of things from an optimization perspective

[hazy sinew]

i have yet to use a single array in aoc at all

[solemn python]

You haven't been using uiua

[sullen fiber]

TRUE

[hazy sinew]

my grid is a Map<Point, T> and thats mostly what i use

and lists

for the input

[solemn python]

Also I'd argue a list is just an array but different

[hazy sinew]

shut up

[sullen fiber]

yea same

array user

⚠️ ⚠️

[hazy sinew]

well how else do u save the lines

[solemn python]

I haven't used any arrays actually (I've used Vecs)

[sullen fiber]

sorry did u say you use strings?

[steady fog]

im having a stroke

[sullen fiber]

⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️

[steady fog]

@warped dust fix

[hazy sinew]

but using arrays for logic not parsing is a death sentence (i did it today and it cost me the global leaderboard)

[solemn python]

Ideally, they should be lying on their side with their head and shoulders slightly raised and supported with a pillow or item of clothing. After this, try not to move them. Loosen any tight clothing, such as buttoned-up shirt collars or scarves. If they are cold, use a blanket or coat to keep them warm.

Hopefully that fixes your stroke

[steady fog]

i give up

[sullen fiber]

part 1 or 2

[steady fog]

i literally

cannot strip the spaces from this string

[solemn python]

lmao

That's your issue??

[sullen fiber]

can u use regex?

    }
    writeln("Part 1: ", points);
    writeln("Part 2: ", sum(cards));
    
    return 0;
}

[teal mountain]

hii :3

[solemn python]

But now I suppose I can say im proud to be the only selfhoster on the list

[warped dust]

selfhosting git so lame

[steady fog]

oh you just hard code the indices

[harsh marsh]

yes lol

they are the same

[solemn python]

false

[hazy sinew]

this looks like c with classes and the kotlin range operator

[warped dust]

who gonn sign up to contribute

[steady fog]

im splitting by chars

|

[sullen fiber]

u dont

[solemn python]

Nothing I host on there needs contributions

[sullen fiber]

email them patches

[solemn python]

I have registrations disabled regardless

[warped dust]

congratulations! your projects are not open source

do you realise how stupid it is

[solemn python]

I mean it doesn't have a license so yeah it's not regardless but

[hazy sinew]

congratulations! your server died and you lost all your projects

[harsh marsh]

idk kotlin does it have lazy ranges / generators?

[steady fog]

yes

[teal mountain]

some of this seems cool, like the range syntax in the array accessor automatically looping (?)

[warped dust]

oooo contributors oooooooo you fear them

[solemn python]

If someone asks I'll make them an account, or they could mail a patch for all I care

I just like having it

[harsh marsh]

yeah its like numpy index syntax you can set/add to a whole slice of an array

[solemn python]

For more contribution-worthy stuff I use codeberg

[steady fog]

its weird if i try converting to int in the same map function it doesnt work but in another map it does

[warped dust]

then What Is The Point

[hazy sinew]

it has start..end and start ..< end and u can use it as a parameter to operator fun get so i can do grid[2..10, 4..19] = '.' and itll make a rectangle from x2 to x10 and y4 to y19

[steady fog]

oh

OH

ok

got it

[sullen fiber]

fire

[hazy sinew]

its op sometimes

[harsh marsh]

I think it's the same in D but I read their docs for the first time 15 minutes ago so

not really sure

there was a section on 2-D arrays but I didn't need it

[hazy sinew]

like that day where you had to check if 2 ranges contain eachother at the start of 2022 you just parsed them into ranges and did parsedInput.filter { first in second || second in first }.size

[sullen fiber]

fire

Range in Range is fier

[hazy sinew]

and for the other part its first.start in second || first.end in second

[steady fog]

oh i dont even

[warped dust]

HOLY SHIT

[steady fog]

i dont even need to convert to int

[warped dust]

IM CRACKED?

[steady fog]

no youre not

[sullen fiber]

FR

CRACKED

CRACKED

[harsh marsh]

yeah lol i realized this

[warped dust]

AAAAAAAAAa

im not

[steady fog]

my time is awful

kill

[hazy sinew]

if one of the elves decided to buy a lotto ticket with duplicate numbers i wouldve cried because .intersect wouldnt work by itself

[solemn python]

I didn't bother checking if there were duplicates, I just assumed there were just in case

[delicate crane]

f32?
I guess any f\d{2} is identifiable as me

[hazy sinew]

i didnt even think of duplicates, got 13 for test and submitted

[hazy sinew]

f00

bar

[solemn python]

You are a 32 bit floating point number now

[steady fog]

@harsh marsh can you help me with mine

[solemn python]

[steady fog]

im getting a really small number

3

[hazy sinew]

day 4?

[warped dust]

wait im almost cracked?

[steady fog]

no rini

[sullen fiber]

i just realized

[steady fog]

you are not cracked

[sullen fiber]

my uiua isnt linear time

it almost is

[solemn python]

You are cracking

[warped dust]

almost linear

[sullen fiber]

yop linear.5

[steady fog]

why am i getting 3

[hazy sinew]

are u using uiua

[steady fog]

no

[hazy sinew]

does cards[] = 1 initialize all elements to 1

[steady fog]

probably

im just on part 1

[warped dust]

¯61264676597997600

@sullen fiber is this correct

[proper totem]

discord is annoying and I made lots of typos

[sullen fiber]

WTF

[hazy sinew]

wtf is walklength

[sullen fiber]

NEGATIVE CARDS

[steady fog]

thing

[proper totem]

staff not impacted by automod when™️

[steady fog]

walkLength must be the number of matches?

maybe

[hazy sinew]

what about .size

[steady fog]

doesnt eixst

[hazy sinew]

goofy lang

[solemn python]

https://github.com/danielhuang/aoc-2023/tree/master I found some guy's repo and holy rust setup

[steady fog]

@solemn python tyminky

[solemn python]

He even has cargo watch running with auto copying answers

And auto submission

[hazy sinew]

did u check if hand and winning are correct

[solemn python]

My setup feels inadequate now

[steady fog]

like reading properly?

[hazy sinew]

mines better

no auto submit tho

[hazy sinew]

yes

[steady fog]

ye

[hazy sinew]

ok i think its gotta be a skill issue then

[steady fog]

yop

so it only counts 2 matches in the first one

Card 1: 41 48 83 86 17 | 83 86 6 31 17 9 48 53

but theres 4

[hazy sinew]

print the set intersect

[steady fog]

["83", "86"]

[hazy sinew]

did u parse " "

before single digit nums

print hand and winning

[steady fog]

card 1:
winning: ["41", "48", "83", "86", "17"]
hand: ["83", "86", " 6", "31", "17", " 9", "48", "53"]
match: ["83", "86"]

[real hinge]

@steady fog i did day 4

[steady fog]

guh

[hazy sinew]

maybe ur intersect caps at the size of the second set
