wakey wakey

AYYYYY FIRST SUCCESSFUL pyproject.toml CREATION WITH KLEIN

:D

@RadvylfPrograms \a and \z should be the versions of ^ and $ that don't change in multiline mode (and also \Z if your $ matches before a trailing newline)

@UndoneStudios that's not golfed you haven't even replaced NULL with 0 yet.

#include <time.h>
main(){time_t t=time(0);printf("%d",localtime(&t)->tm_year+1900);}

@DialFrost what?

@Steffan how'd you do inventory seq?

guys is there a way to add a chessboard to a post like they do in chess se, or is that only exclusive to that site?

lyxal

looks like a chess only feature

Aiden Chow

rip, trying to make a chess related challenge, that makes a bit more difficult i suppose

should i just put a pic of the board state instead? how should i be doing this?

Unrelated String

yeah just do that

also have a text version

Aiden Chow

is this fine?

also when im explaining which piece moves where, should i just assume that the reader is familiar with algebraic notation or do i have to provide an explanation of that somewhere in my post?

or maybe i just provide the wikipedia link for algebraic notation in my post?

lyxal

~~make sure you explain how the horsey moves, because that's one of the hardest things about chess (looking at you Garry Chess for making it so hard to understand)~~

~~also where Knooks?~~

Ginger

2:18 AM

self.props.parent.props.parent.editor.openProject(project) yes this is good and normal python code

Aiden Chow

ok wait i have to explain how every piece moves too?

lyxal

(no - not knowing how the horsey moves is an r/anarchychess joke)

Ginger

but how does the horsey move

lyxal

good question

I don't know

Ginger

you don't know???

lyxal

2:25 AM

I'd have to ask Gavin from 3rd grade

Ginger

well go get him then!

lyxal

all I know is en passant is forced and double check is checkmate and pasta

Ginger

...

what

code-golfdecision-problemchess Is it a valid atomic chess move? Background and Rules There is a variant of chess called atomic chess, which follows essentially the same rules as normal chess, except that pieces explodes other pieces around them when captured. In addition to checkmate, you can al...

lyxal

~~don't forget that the king can't move to C2~~

~~and that en passant is forced~~

Aiden Chow

O_O

feedback btw, idk if i should put more general info about chess to make the challenge more accessible, or if its already long enough as it is

emanresu A

Lyxal, do you know anything about chess aside from the memes?

lyxal

yes

I used to be good at it

Aiden Chow

@lyxal lol rip, do u not play it anymore or what

lyxal

5:21 AM

that's right

Aiden Chow

lol me too, i feel like i havent really touched normal chess in a while

lyxal

chess memes are the only thing about chess I get nowadays

Aiden Chow

im like way better at the atomic chess variant than normal chess lmfao

@lyxal lmaooooo

ok seriously tho could someone take a quick look over my sandbox post and see if theres any glaring problems

DialFrost

5:37 AM

@AidenChow exclusive to that site

@lyxal :(

@AidenChow lmao

DialFrost

6:09 AM

@Steffan how'd u get first for long percirinous

DialFrost

7:19 AM

why doesnt this work for this challenge?

for i=0:10000
n=count_ones(i)
if 0∉n.%(2:n-1) println(i)end
end

???

pxeger

7:50 AM

@user yes that was my point

Jo King

@DialFrost do a new hole before anyone else does it

DialFrost

@JoKing but i want basically a permenant diamond (ok not permenant but ya)

@JoKing and ppl take over quick

CMC Given an array of 0s and 1s, output the decimal number that corresponds to the array when it is considered as a binary number. E.g [1,1,1,0] ->14

hyper-neutrino

this is the Ḅ built-in in Jelly, B in Vyxal (and surely every other golfing language has it but i'm not gonna list a thousand things lol)

If you followed the language design SE site consider moving your votes down lower since the top few all have over 10

@DialFrost *2nd. pysearched a primality formula

@emanresuA no it was just created a few hours ago lol

all your diamonds will be gone soon

Steffan

2:37 PM

I just sniped most of them, you've got 4 left lol

@DialFrost bcs 0∉n.%(2:n-1) counts 1 as a prime

@graffe GRIP

ooh i found a book

Ginger

uh why tf is MSEdge asking if I'd recommend it

mousetail

Well do you?

Ginger

not really

although I recently learned it apparently has userscript support built-in, which is neat

mousetail

That's... suprising. The last browser I would have expected to have that

Ginger

exactly!

graffe

3:39 PM

@PyGamer0 why GRIP?

where'd you find the 204 byte cobol solution for abundant numbers?

@Steffan then how?

We've got only ten days until December and need 10+ more challenges for Code Golf Advent Calendar!

DialFrost

@Bubbler WW can cover for it :3

Steffan

@DialFrost just add &&n>2 or smth like that

DialFrost

@Steffan but...but... that makes me have 60 bytes

:|

Steffan

that's why you don't actually check for primality

ALSO, USE .|>

DialFrost

i did lol

hehe

Steffan

11:50 PM

NO YOU DIDN'T

DialFrost

@Steffan 1:10^4 .|>i->0∉(n=count_ones(i)).%(2:n-1)&&n>1&&println(i)

Steffan

oh

you didn't post that

DialFrost

lmao

Steffan

that's better lol

DialFrost

@Steffan then how leh

@Bubbler really sorry but i cant contribute :(

Bubbler

11:51 PM

no problem

Steffan

same here, i never have any ideas

DialFrost

@Steffan i too never have any ideas + too stupid to actl come up with a decent challenge

Steffan

Does it save any to use sum(n.%(1:n).<1)==2?

I'm too lazy to check

DialFrost

no

it went from 60 bytes to 60 bytes

and 58 chars to 60 chars

Steffan

ok lol

DialFrost

11:53 PM

so its actually longer

Steffan

if you want to save chars then one sec

replace && with ≠

comparison chaining

DialFrost

@Steffan thats 3 bytes so it adds 1 byte extra

unfortunately

Steffan

I know but it saves chars

It adds bytes

DialFrost

:/

welp how'd u get 45 ... hint? :p

Steffan

like i said, pysearching a formula lol

it's length 10

DialFrost

11:55 PM

@Steffan i canttttt

my comp cant get past length 8

@Steffan how long did you take to get that (runtime)

Steffan

about 5 mins maybe, but i have a pretty fast computer

DialFrost

5mins?

oh

i've been waiting for around 1min b4 getting impatient :3

Steffan

however even on my computer it likes to crash with [1] 200 killed ./a.out

i think it means it ran out of memory

DialFrost

what inputs/outputs did u use

Steffan

i've pysearched stuff since so it's not in the file anymore

DialFrost

11:57 PM

@Steffan ?

Steffan

let me try get some inputs/outputs again

the results from bit_count will be from 0 to 13, so that's your inputs

the outputs are just 1/0 for each if it's prime or not

DialFrost

gimme a sec

@Steffan 0 1 2... 13???

or any few numbers from that range

Steffan

you can probably omit a few

but you'll need most or it'll find all kinds of junk
