i'm kind of afraid of the very idea of a jelly codebase

lyxal

auto-challenge generation is surprisingly not good

Unrelated String

i guess you can use python eval to split things up across files some way or another

user

Linting and autocompletion would be a mess

caird coinheringaahing

@UnrelatedString I've written projects in Jelly

Not professional ones, but also not not professional ones

4

My old job had some curve fitting algorithm they wanted me to rewrite, and I couldn't be bothered to use Python, so I just wrote a Jelly script to do it and changed their system to call that instead of the Python program

Their old algorithm is still there, it's just not as good as my Jelly one :P

@hyper-neutrino @RedwolfPrograms @UnrelatedString okay we finally have a consensus on the funniness of that message

hyper-neutrino: it's not funny enough to be funny
Redwolf Programs: It's not funny, but in a funny sort of way
hyper-neutrino: it's not funny enough to be very funny
Unrelated String: and since it isn't about me i don't think i'll remember it
Redwolf Programs: I think that one is the funniest one so far. It's also the only one that doesn't make me laugh. I'm going to go with "not very" on this one.

And probably got some pings that required a lot of context lol

hyper-neutrino

Yeah well the first ping I got was yours about Bubbler, and my only comment is that any crush on me is an unhealthy one. It's okay Bubbler, I'm here if you ever need to talk about it.

@lyxal Comedy, but I didn't laugh.

@OldSandboxPosts isn't Ambigous formula challenge posted?

Wasif

@lyxal we already have them dont we

hyper-neutrino

1:34 AM

no i don't think so

does vyxal have any operators really?

or does everything require a function object and working with that on the stack?

Wasif

err I see everything is function

which pops values from the stack

looking at the source code

lyxal

@hyper-neutrino not yet

That's going to be part of my experimental branch

Or experimental fork if that makes more sense

DLosc

@Wasif My toy language Zephyr has fractions. (Actually, it doesn't have floating point!)

Also I think a lot of Lisp dialects have a built-in fraction type.

Wasif

@DLosc oo nice i will definitely take a look

@lyxal Can we have a is_palindrome builtin for Vyxal?

hyper-neutrino

an invariant-under operator would probably be a more applicable and better idea

though having a shorter is-palindrome might be nice too

A username

Wdym "an invariant-under operator"?

hyper-neutrino

given a function f and a value x, is x = f(x)

A username

Sure, i guess.

hyper-neutrino

it's quite useful IMO

At least from a compatibility standpoint I consider chrome and FF to be equals, but that's about all the experience I have with it

Redwolf Programs

You got the weird caching issues resolved?

hyper-neutrino

i still have privacy badger running

Redwolf Programs

I'd consider switching over, but it's a bit slow (and ironic) on a chromebook

Wasif

4:53 AM

@Underslash IDK if builtins have been disallowed

Underslash

hopefully so for anything is a single operation type thing

Code Golf Stack Exchange

@Underslash True. So should it be posted or not? It's kolmogorov-complexity, so it's just a string output challenge, after I scrapped the input bit.

Underslash

Well, the problem is that I think it would just be a simple "logic translation" from that challenge to yours if you get what I mean

so if there was a good formula for that one, it most likely would work exactly the same for yours

Code Golf Stack Exchange

I will make it "challenge scrapped" if it's no longer a suitable challenge. It has a score of 1 though, so I'm not sure yet.

Underslash

im just afraid if you post it, it will get marked as a dupe

Code Golf Stack Exchange

"Challenge scrapped" it is, unless it's not the final feedback.

I am personally starting to think that maybe, just maybe, introducing GPT-3 to code golf was a bad idea.

I put in a list of everyone currently in TNB

unless the AI somehow has met with Caird in person,

it managed to generate Caird's irl name

I mean sure, it has some stupid things like Dictator of the United States

but combined with the accuracy of some of it's earlier suggestions, I think there might be a few too many coincidences to not be sentient

caird coinheringaahing

Z erroring on integers has been an old trick for challenges that ask for errors in specific cases

@hyper-neutrino MTZz always error on integers. X errors on strings/negatives. Quicks always error if they don't have enough preceding links. Ɠ errors if eval fails on the STDIN line. Ɠɠ both error if there's no more STDIN, ¡ and # both error if there is no more STDIN assuming they only have 1 link. G fails if the argument has both a list and an integer at the same depth (e.g. [1, [1]]). y fails if passed a list with an odd-length. b fails if the right argument is complex

caird coinheringaahing

I suppose you could make a goal out of it: "How high up the 'currencies by strength' ladder can you go while still being a 'miilionaire'?"

Like, if you have $1, you're on the 'bottom rung'. Then at $4 you reach "millionaire" in Iran (1USD = 230,000IRR). Then, you need $40 to go one higher and so on

caird coinheringaahing

Maybe. But, for now, this is a list of "In order to be a 'millionaire' in the 10 weakest economies, you need this much USD" (according to this article)

if you know the range and it's uniform enough, def radix sort
