The Nineteenth Byte

How to get cheap upvotes: Make a language with Jelly's code page, and give it a sufficiently similar name to Jelly (like JeIIy) that people will get confused.

Mr. Xcoder

@HyperNeutrino Everything is wrong

Challenger5

7:25 PM

@BusinessCat I know that's true, because I just used it.

Business Cat

@HyperNeutrino I thought it was supposed to end at 1 not 0

HyperNeutrino

I lied

I didn't look carefully lol

@cairdcoinheringaahing correct. now read the question through again because we both messed up lol

AdmBorkBork

@Mr.Xcoder PowerShell, 24 bytes

HyperNeutrino

@BusinessCat right, thanks.

AdmBorkBork

I like the +-- in the middle

Mr. Xcoder

7:27 PM

CMC: n -> [0...n...1]

@AdmBorkBork Nice

HyperNeutrino

Programming in Jelly consists of 2 steps: 1. Understand the confusing tacit flow 2. Read the codepage and copy atoms and quicks (and syntactical components) over to do something

AdmBorkBork

@Mr.Xcoder Similar, just do $n--+$n in the middle instead

totallyhuman

@Mr.Xcoder [0, 1, 2, 3, 2, 1]?

Mr. Xcoder

@totallyhuman For an input of 3 yes

caird coinheringaahing

@HyperNeutrino @Mr.Xcoder Jelly, 4 bytes: ḶŒBṖ

Business Cat

7:28 PM

Gaia, 4 bytes: )…ṫḣ

Mr. Xcoder

5 bytes: +UQ_S

AdmBorkBork

22 in PowerShell

HyperNeutrino

@cairdcoinheringaahing for [0...n-1...1]?

5 bytes in Jelly for the more recent CMC (@cairdcoinheringaahing)

should be really easy lol

caird coinheringaahing

@HyperNeutrino for the one before latest

HyperNeutrino

okay. correct :)

Business Cat

7:29 PM

Anyway I should probably continue making the language instead of doing CMCs in it

caird coinheringaahing

I would try but Leaky has set me a challenge to do

so bye!

@dzaima Is I increment?

dzaima

@Mr.Xcoder yeah

Mr. Xcoder

Hooray, I guessed right

totallyhuman

Mr. Xcoder

@totallyhuman Ninja'd by far by the OP

AdmBorkBork

For when it's really yeah

Mr. Xcoder

7:33 PM

Your turn

HyperNeutrino

CMC: n -> [0, n, 2n, ..., n^2]

AdmBorkBork

CMC: Given input n output the nth Pythagorean triple, where n=1 results in 3,4,5.

HyperNeutrino

CMC-ninja'd

Mr. Xcoder

@LeakyNun Do you have a set of assignments you give to all of us when you teach us how to golf in that language? Or do you just reuse your old CMCs?

@HyperNeutrino What if n=1?

HyperNeutrino

then [0, 1]

Business Cat

7:35 PM

@AdmBorkBork So what is the result for n=2?

totallyhuman

@HyperNeutrino vectorised product of range (n) and n?

HyperNeutrino

yes

but it's range(n+1)

Mr. Xcoder

@HyperNeutrino What do you mean by those ellipsis? If 3n<n^2, 3n, if 4n<n^2 4n and so on?

HyperNeutrino

The Jelly solution to my challenge is 3 bytes. (@cairdcoinheringaahing)

Business Cat

@HyperNeutrino Gaia, 5 happy bytes: :)…×¦

AdmBorkBork

7:36 PM

@BusinessCat The second Pythagorean triple, (5, 12, 13)

dzaima

@HyperNeutrino SOGL, 3 bytes: ∫*P

Leaky Nun

@Mr.Xcoder I reuse my old CMC or I make up a CMC

HyperNeutrino

@Mr.Xcoder It's just lambda n: [k * n for k in range(0, n + 1)]

Mr. Xcoder

@LeakyNun Thanks

Leaky Nun

@AdmBorkBork ordered by?

AdmBorkBork

7:37 PM

Sorry, I'm missing the word primitive.

Ordered by smallest a in (a, b, c) where c is the hypotenuse.

Mr. Xcoder

@LeakyNun I asked because I saw you used the same for cairdcoinheringaahing

totallyhuman

@HyperNeutrino 0r×?

wait no that wouldn't work

HyperNeutrino

@totallyhuman That's one way to do it :)

@totallyhuman well it does

totallyhuman

it would? i clearly don't understand chaining

Mr. Xcoder

@HyperNeutrino m*QdUh

HyperNeutrino

7:39 PM

I don't either :P I just happen to know that it works :P

Business Cat

Anywhere it's missing an argument, it uses an input

HyperNeutrino

@Mr.Xcoder Pyth?

Mr. Xcoder

@HyperNeutrino what else?

HyperNeutrino

xD

Business Cat

That's the really really simplified version

Challenger5

7:39 PM

@HyperNeutrino CJam: {_),\f*}

HyperNeutrino

oh I didn't look at the link

Mr. Xcoder

Thx

HyperNeutrino

@cairdcoinheringaahing Have you found a 3-byte Jelly solution yet?

oo

wait no that's wrong

Jim

@Mr.Xcoder Or m*dQ}Z

Mr. Xcoder

@Jim That too

HyperNeutrino

7:40 PM

@Challenger5 question: why do you always edit your CJam CMC submissions :P not judging you, just curious xD

caird coinheringaahing

@HyperNeutrino Check hypertraining. I'm doing that. In about 20 bytes

HyperNeutrino

Okay.

I should try that sometime

Challenger5

@HyperNeutrino Because I usually edit my submissions, and most of my submissions are in CJam. In this case, though, it was because it was invalid.

HyperNeutrino

ah okay.

AdmBorkBork

Maybe I should make my CMC into a MC

Mr. Xcoder

7:42 PM

@Jim wanna make pyth training together?

Jim

@Mr.Xcoder Yes I do

totallyhuman

Mr. Xcoder

7:48 PM

@cairdcoinheringaahing There is already a sleepy Pyth room

caird coinheringaahing

@totallyhuman yeah but I'm pretty sure he said he didn't want anything to do with hypertraining when it was made

HyperNeutrino

Jelly Hypertraining requires commitment, ya know. It's not a simple matter of "after you finish". Heck, I don't know how long that will take me xD

Mr. Xcoder

@HyperNeutrino ~90 years?

HyperNeutrino

@cairdcoinheringaahing then you should ask isaacg too before making him have something to do with Pyth Training

caird coinheringaahing

@HyperNeutrino did it take you that long to write that comment?

HyperNeutrino

7:49 PM

no

Challenger5

What do you actually do at Hypertraining?

@totallyhuman So I don't actually have to join. I can just read the transcripts and solve the problems myself, right?

caird coinheringaahing

Yeah but you can't get help that you want

Leaky Nun

I just devised an algorithm to find partition(N) with polynomial complexity :o

HyperNeutrino

You can if you want, but then you can't ask Erik and Leaky for help

@LeakyNun :o nice

(well at least not in HT, TNB still exists)

caird coinheringaahing

7:51 PM

Well you could ask in here, but that might not be good

HyperNeutrino

HT was created to prevent TNB and Jelly students from interrupting each other lol

Leaky Nun

in fact the complexity should be O(N^3)

Downgoat

@LeakyNun >_< can you explain what does partition(N) do without integral symbol?

Leaky Nun

@Downgoat the number of ways N can be partitioned into sum of positive integers

5: [5], [4,1], [3,2], [2,2,1], [3,1,1], [2,1,1,1], [1,1,1,1,1]

Challenger5

@HyperNeutrino I've been asking for golfing advice on CG'C

Downgoat

@LeakyNun ah, huh, cool :D

HyperNeutrino

@Challenger5 what is that

Challenger5

@HyperNeutrino Code Golfer's Corner. It's that one nobody used until it was mentioned on Meta recently.

Leaky Nun

here is my R code

HyperNeutrino

ah ok

totallyhuman

@LeakyNun are you adding R to the long list of languages you know?

Leaky Nun

7:55 PM

@totallyhuman yes

totallyhuman

damn

do you ever get confused

Leaky Nun

@totallyhuman always

Challenger5

I sometimes get confused, and I only know like 4 languages!

Leaky Nun

Though I'm sure my O(N^3) algorithm must have been discovered before me

Conor O'Brien

do you have a physical list of "languages you know"?

Challenger5

8:00 PM

@LeakyNun this might be relevant, but it's too much math for me at the moment

Leaky Nun

@Challenger5 now that's an O(N^2) algorithm.

@ConorO'Brien I don't

Challenger5

Do you know more practical languages or esolangs?

Leaky Nun

@Challenger5 no idea

AdmBorkBork

@ConorO'Brien On my resume.

It's rather small.

Business Cat

Just PowerShell? :P

AdmBorkBork

8:15 PM

VBScript and HTML

plus a little Java

I'm probably really rusty on my Java and VBScript, though.

Just because 99% of my answers here are in PowerShell doesn't mean I'm only a PowerShell coder.

totallyhuman

mutters wish java would rust

AdmBorkBork

That's languagist.

I don't know Rust.

Business Cat

To be fair, PowerShell is the best golfing language out of the above...

Phoenix

\o/

AdmBorkBork, haven't seen you in forever

AdmBorkBork

PowerShell can be rather golfy.

/wavehi

On average, it's about the same as Python or JavaScript.

totallyhuman

@BusinessCat false

empty is always false :P

Business Cat

Yeah that's true

totallyhuman

8:36 PM

0, "", []

Business Cat

Empty list is false...

AdmBorkBork

They should return back an empty Boolean value, haha

Jim

@BusinessCat In Python, all([]) is True so I would say "all true"

caird coinheringaahing

@Jim bool([]) is false

Business Cat

But "all false?" is all([not i for i in l]) which is still true for []

Jim

8:38 PM

@cairdcoinheringaahing Yes but "all true" translates to all(), not bool()

AdmBorkBork

yeah, you'd want the all false? to be truthy for [], imho

totallyhuman
