here's a fun one: Vyxal 3, 14 bytes: 2√①k1*×⌊1'.⎀“, Vyxal It Online!

the tooltip for “ says it's for the compressed strings thingo, but it's also join on nothing

Bridget

[RubenVerg] it's join on nothing at the very end of the program only

[RubenVerg] iirc

Themoonisacheese

13:13

i tihnk it's just join on empty string only if it's not closing a string

which makes sense

(also, code.golf seems to have disabled implicit printing?)

lyxal

13:50

yes

explicitly too

--disable-output is passed as a flag

quine cheese prevention

@Themoonisacheese it's join on nothing if not closing a string

...which is what you said anyway I didn't read that part I only read the bit about printing being turned off not the part where you clearly stated the behaviour which I happened to repeat without knowing I had been, essentially, ninja'd but that it wasn't a necessary ninja nor a ninja of rapid fire chat, but a silly one

Themoonisacheese

born to be silly, forced to golf :(

@lyxal that's a bit sad, i feel like it's not very fun to add 1 char to every submission just to save a challenge that is silly to beign with

yes, quines are silly, i said it, fight me liberals

lyxal

@Themoonisacheese I don't fully agree with it either

but I see it as something that keeps the peace, as such

Themoonisacheese

then again you did implement ℗

lyxal

"implement"

please

Themoonisacheese

yeah ok

lyxal

14:00

I stole it from Jelly

Themoonisacheese

@Themoonisacheese do you have a suggestion to do this in a better way?

most of the code is straight up just multiplying a float so i have access to the amount of digits required

lyxal

that's actually pretty smart

Themoonisacheese

and i feel like there's a simpler way

lyxal

would be if I had actually implemented "to n decimal places"

Themoonisacheese

ah

@lyxal i actually didn't think this would work, i thought that the precision of 2√ would just be wrong after the default display (or be all 0s), i was pretty surprised to see that it did actually compute up to that

lyxal

14:06

Why wouldn't it work?

Everything is arbitrary precision after all

And surds are stored exactly under the hood

Themoonisacheese

@lyxal that's the part that surprised me

lyxal

It's the part that makes supporting scala native 0.5 impossible :p

Themoonisacheese

lol

lyxal

(the underlying library hasn't been version bumped)

@Themoonisacheese exact numbers like that was actually a fundamental design choice lol

Something that was absolutely going to be a thing

Just like it was in v2

Although it was easier in v2 because Sympy is so extensive

Themoonisacheese

yeah i was about to ask if that was why sympy

lyxal

14:09

Half the reason

Exact numbers + symbolic algebra

Even if it did mean ACE exploits :p

And weird fraction representations

Of whole numbers

Themoonisacheese

@lyxal ACE? in your interpreter? it's more likely than you think!

Bridget

[the cat] can't believe my program which I wrote to execute arbitrary code has the ability to execute arbitrary code

lyxal

@Themoonisacheese especially when the library you're passing user input to uses exec under the hood and can easily be escaped :p

Themoonisacheese

bruh

lyxal

Yeah

Meant you could insert arbitrary python calls

Even on the online interpreter

Had to remove all algebra stuff for a while

A: Inject arbitrary code into a compiler (robbers)

Cracks Vyxal 2.10 `f"{print(1)}"`∆i Prints 1 then errors. Sadly does not work online, but does offline. Exploits the fact that ∆i uses sympy, similar to this. Injected code is everything between the { and }.

Themoonisacheese

14:17

then again v2 had arbitrary python eval???

lyxal

Offline

But yes because it was surprisingly useful

The ace problem was that it wasn't disabled online

Even though python eval was

Themoonisacheese

mhmh

lyxal

Meant you could write files to the server

... Which people did

Because that's the vyxal way after all

2021 was peak

Themoonisacheese

did v2 not execute in the browser?

Bridget

14:56

[user] No, it executed on the server

Themoonisacheese

incredible

Themoonisacheese

16:06

is code.golf/semiprime-numbers#vyxal impossible in vyxal?

given the 5s timeout

i have Vyxal 3, 13 bytes: k2ɾ(n∆æ∑2=¿n, Vyxal It Online! which i'll concede is very much not efficient but it doesn't even reach 1000, much less 10000

Bridget

16:38

[RubenVerg] i have a working 23

[RubenVerg] which can probably be optimized a lot

[RubenVerg] it takes 2.7s

[RubenVerg] and it's much simpler than you think

[RubenVerg] golfed to 18
