It's the fault of keeping the sequence "lyx"

user

xylal (kill-all)

Bubbler

so it pronounces [whatever]-licks

emanresu A

Get licked

Bubbler

lylax (somewhat like Gygax)

A: Sandbox for Proposed Challenges

Counting and so on code-generation Content You count numbers every day (I think), and most of you know how to count properly, the one next to 1 is 2, and the next is 3, so go on, no matter what number you receive, you can easily know what next number is. Anyway, the program doesn't know, they are...

@user That sounds like some chemical

Dude coinheringaahing

Q: Boustrophedon transform

Related: Boustrophedonise, Output the Euler Numbers (Maybe a new golfing opportunity?) Background Boustrophedon transform (OEIS Wiki) is a kind of transformation on integer sequences. Given a sequence \$a_n\$, a triangular grid of numbers \$T_{n,k}\$ is formed through the following procedure, gen...

@user We should make that a site ads

What?

drake-no: committing mod abuse via doing bad things to other users

So you can ignore mods?

I took Lyxal and after just four weeks, I lost 40 pounds, remembered every event which has ever happened to me, my skin started literally glowing, and every microbe within ten feet of me dies when I look at it.

okie

@hyper-neutrino That's overkill, vyxal must be crying rn

user

@Bubbler Yoo can ignore anyone

exedraj

@hyper-neutrino proceeds to remove you from the github organisation

Oddly enough, you can see messages from ignored users in other rooms in the preview thingy to the right

(It's a big image, so you'll have to click on it to see the whole thing)

Q: Rows of the Collatz tree

Consider a binary tree built the following way: The root node is \$1\$ For a given node \$n\$: If \$n\$ is odd, its only child is \$2n\$ If \$n\$ is even, one of its children is \$2n\$. If \$\frac {n-1} 3\$ is an integer, its right child is \$\frac {n-1} 3\$ Recursively and infinitely define ...

@Dudecoinheringaahing thanks, I applied your suggestions. I think I'll be posting the challenge tomorrow morning, then: codegolf.meta.stackexchange.com/a/23793/55934

okie

@user The cat team is literally all ignored

user

You can't ping me anymore @okie (the only reason I saw your message was because I was in Vyxal and I saw TNB's preview)

okie

@user Oh no, this is a one-way chat DOS attack, i am getting pinged to death

user

12:25 AM

I should really stop ignoring everyone lol

Anyway, gtg to go sleep, please don't nuke each other, cats and identicons o/

@ngn You have joined the cat side! Welcome, and can I have some help golfing this?

ngn

@emanresuA thanks :) sure: you can write a x instead of a[x]

emanresu A

Oh

that's niec

ngn

@emanresuA the innermost lambda could be shortened like this: { .. }[x;x] -> { .. }/2#x because x is an atom

emanresu A

Ok, cool!

Allyx

Oh frick I just realised I meant to make my username allxy because x comes before y in the alphabet

Big brain time

ngn

12:54 AM

@emanresuA then we can eliminate the middle { } like this: {[a]{$[y;o[x;y-1]+o[x-1;x-y];a x]}/'2#'!#a} or like this: {[a]i{$[y;o[x;y-1]+o[x-1;x-y];a x]}/'i:!#a} (same byte count)

emanresu A

Oh, that's very nice.

BTW When you map a function over a list, what is y inside the function?

In JS it's index

ngn

@emanresuA if you have a y (i.e. your function is dyadic) and are using each, then you're probably mapping over two lists

emanresu A

Oh

And this works because ' is a primitive, not a function, right?

ngn

@emanresuA that was actually a good question. the / is unnecessary :)

{[a]i{$[y;o[x;y-1]+o[x-1;x-y];a x]}'i:!#a}
