12:08 AM

Yeah

But it implemented modulo, so there's a probably a shorter solution by taking every third element and filtering out the ones that are too small

Destructible Watermelon

that's why we gotta try hard and make it possible!

@WheatWizard CMC: largest number in 32 bytes of brain-flak

Actually wait, I have a more interesting one

CMC: what is smallest positive integer that can be printed in n bytes of brain-flak but can't be printed in n bytes of mini-flak?

Destructible Watermelon

doesn't miniflak not have height of stack?

Positive because otherwise the trivial answer is 0: (<>)

Destructible Watermelon

yeah I was gonna say

12:15 AM

@DestructibleWatermelon No, it does. It doesn't have the alternate stack or the <...> monad

Oh wait, duh. ([]) works in mini-flak too

Destructible Watermelon

> Miniflak also stipulates that its square braces never be empty. That is to say that the square nilad is banned from use.

Christopher Peart

@Riker Wait you're 14?

yeh

no he's 95

lol

Christopher Peart

Wow

I am older than you too

I feel so powerful

12:17 AM

@DestructibleWatermelon Wait, huh? Link plz?

To everyone who responds to everything by saying they've 'lost their faith in humanity': Thanks--I'll let humanity know. I'm sure they'll be crushed.

Destructible Watermelon

also on the miniflak quine challenge

s/stupid/young/; s/smart/old/

mainly the last panel

@DestructibleWatermelon huh. I didn't realize there was an esolangs page for that. That makes my challenge easier though

Q: Tell my friends to which "comma club" they belong

Inspired by Silicon Valley's "three-comma club" scenes, like this one, in this challenge you'll be telling ten people the "comma club" to which they each belong. If you're unfamiliar with the term "comma club," let me explain: you're in the one-comma club if the money you have is in the inclusiv...

@Pavel :D

Christopher Peart

12:19 AM

@ConorO'Brien please tell me you are older then me

how old are you?

@NewMainPosts Try it online!

Christopher Peart

16

month?

Christopher Peart

October

12:20 AM

we're basically the same age

Christopher Peart

Are you a bit older?

I don't want to ask about the day but as for the month/year we're the same

Christopher Peart

Wow

That is scary

indeed

tbh 90% of people on ppcg are pretyt young

Christopher Peart

12:22 AM

This has been an enlightening day

Haha, that means I existed in a different millennia then both of you :P

@DJMcMayhem Miniflak does not have []

Yeah, I didn't realize that

Christopher Peart

@DJMcMayhem Finally a person older than me

Destructible Watermelon

It's kind of weird when you think about it that there are people alive who have lived in different anthropological eras

12:23 AM

tbh most of the older people left TNB >_>

yeah

it's sad

Christopher Peart

I feel young

@ChristopherPeart why

Christopher Peart

Wait

I meant to type old

facepalm

12:24 AM

You're not

Christopher Peart

I am not

I feel old now. So many people are younger than me and yet they can code better

:P

Even the ol' Geezers in here aren't old

Christopher Peart

Is Dennis one

Dennis is old enough to get tenure

he's 96

12:25 AM

Feb 14 at 6:11, by Dennis

Trying to get tenure.

@Dennis Speaking of ^, how'd that work out for you?

Christopher Peart

@ZachGates Hey i did your bounty in milky way

link?

Christopher Peart

0

A: Notcalc (Calculate the wrong answer)

Milky Way 3 bytes +R+ Adds top 2 stack items then pushes one and adds again. http://meta.codegolf.stackexchange.com/a/8493/63187 allows me to assume the inputs are pushed to stack. Also finishes this bounty

Now he has to answer it

May have a 1 byte answer

uh

tha'ts not fulflilled yet

and "fewer" doesnt' mean "equal"

Christopher Peart

Wait he answered?

I was trying to get him to answer

12:30 AM

no

but that's not fulfilled yet

and even if he does, then he can easily come up with the same solution

and the bounnty said "fewer" not "equal bytes"

Christopher Peart

Yeah i have to wait for him to answer now. I guess i will move on

no, my point is that doesn't work

because he can come up with the same solution

and that means no bounty

Christopher Peart

Edits made

that's a ridiculously simple challenge also

Christopher Peart

Yeah finding a new answer

Wait question

@ZachGates can you answer some challenges in milky way so i can try and beat you?

12:34 AM

CMC cube a number in Brain-Flak

I can cube a number

@ChristopherPeart standard loophole

@JanDvorak we're starring this? ok

stars

Christopher Peart

But... he forgot to put rules :P (sarcasm)

12:37 AM

@DestructibleWatermelon what goal ;p

By the way this squares a number if thats any help.

Christopher Peart

I can do to the 4th power

@WheatWizard hmm... I was going to go have dinner but that sounds more fun

8

I just read the language description on esolang, and now my head hurts

@DJMcMayhem As someone who is currently eating lunch and trying to solve this problem at the same time, I must say that those two are not mutually exclusive.

12:41 AM

@JanDvorak Thats natural, eventually you get used to it and start having fun

@WheatWizard Well, I've got this: Try it online! but I'm positive it can be much shorter

Like Dark Souls

Except not as hard

How long until I'm able to make a "useful" program in this?

@JanDvorak Possibly never

In Dark Souls you don't need to learn how to hold a sword.

12:42 AM

You don't need to learn how to pop a number from the stack in BF, either.

*Switch stacks

@DJMcMayhem That looks like it's squaring, not cubing.

3 ** 3 == 27

It yielded 9 for me

Christopher Peart

When TIO gives you a cache hit youtu.be/CX9zYuLBlhg

12:44 AM

Uhhh, not really sure what to say. It's definitely giving me cubes

Christopher Peart

Cubes for me too

We're talking about ({({})({}[()])}{}), right?

I'm wondering if there's a game where at zero familiarity with a weapon you have a risk of hurting yourself just from wielding it. "wG - you hold the sword backwards. You stab yourself in the left thigh (-3 HP) - wG - you grab the sword by its blade. Your leather gloves partially block the bleed. (-1 HP / turn)"

4

@Pavel No, ((({}))){({}[()]<(({})<>{})><>)}<>({}<>{}){({}[()]<(({})<>{})><>)}<>

Ok

Why did I get ({({})({}[()])}{}) from that link then?

12:46 AM

I have no idea

Wierd

Christopher Peart

You clicked your own TIO link?

I don't write BF though

Christopher Peart

@Pavel Woops you clicked WW link?

Ehhhh IDK

12:49 AM

@WheatWizard Well, I got it a tiny bit shorter, but not as much as I'd like: Try it online!

I bet it can be sub-50 bytes

I see a fish in there!

@DJMcMayhem But can you beat Java?

interface g{static void main(String[]a){System.out.print(Math.pow(new Integer(a[0]),3));}}

Ahh, there we go. Now that's a solution I'm happy with. 56 bytes: (({})){({}<(({}))>[()])}{}{{({}[()]<(({})<>{})><>)}{}}<>

@Pavel I believe I just did

thatsthejoke.jpg

@Pavel what happens if you omit String[]a?

Also, 3^ in stacked

12:56 AM

->x{x**3}

@ConorO'Brien Cannot find or load method 'main()'

weird

Besides, I need it because that's where I pull input from.

You know what that means? Now it's actually dinner time.

(Unless of course, someone were to distract me with a string-based CMC)

A: Sandbox for Proposed Challenges

Create an ASCII art jumble! Given a string of ASCII art like such: | | +-- | | +-+ |-| +-- | | | | | | +-- +-- +-- +-+ Jumble it as if it was being displayed on a screen with one character per line, like so (I will only do this to the top line to save space): ...

12:57 AM

@DJMcMayhem Sure, I've been saving one

Let me type it up.

Here is my solution

CMC: given a string, "mirror" it, by reversing it and swapping pairs of (), {}, <>, and [].

@DJMcMayhem I will make you starve rofl

Example?

@WheatWizard Wowww, single stack. Nice!

@WheatWizard Does it have to be stack clean? Here is 54 bytes non-clean: tio.run/nexus/…

12:59 AM

<Hello> => <olleH>, => => <=

@ConorO'Brien Thankfully that would be a major pain in the butt in V, so I probably won't starve, haha

aww ok ;)

@DJMcMayhem I forgot there was a second stack

Although it does remind me that I still need to add the vim-abolish plugin.

And a reverse operator, haha

@DJMcMayhem Given a string contating any ascii, determine wether or not it has 4 or more 0s or 1s in a row in it's binary representation, that is U3 passes because it looks like 0101010100110011, but 48 does not, because it has 4 zeroes: 0011010000111000. This is restricted-source, so your code must pass the same criteria.

1:02 AM

That sounds main-worthy IMO

I'll post it later today then.

Think about it, if you want.

sandbox first

@DJMcMayhem aww I wanted to make a language like this lol

@Pavel I wrote a similar challenge a while back. link

I hope mine will be more intresting, and a bit harder.

I don't know about harder

I think it might be a bit easier

1:06 AM

Maybe, but you have to be more careful since the condition stretches between characters.

@WheatWizard Space: 00100000

Tab: 00001001

So, no whitespace allowed.

Might actually be rather difficult.

00001010, lf

cr is the next few up

It might be no whitespace really isn't the end of the world though

@WheatWizard for some languages it is

Whitespace

C, Java, C++, probably python...

1:11 AM

Carriage return is 00001101, so close but so far.

All 2d langs

Destructible Watermelon

@Pavel woah woah slow down there

I think it can be done in python

Destructible Watermelon

some use other chars for nops

@ConorO'Brien I think for python you can stick parenthesese in wherever you need to.

Destructible Watermelon

at least one can use one based on the genus

1:12 AM

@Pavel I mean, it's harder because you can't use def or lambda

{} is banned so no C syntax languages for sure

Destructible Watermelon

well, is exec valid for a program?

I mean what are the bits one those?

Java has a loophole for restricted source where you can substitute every character with \[codepoint]

Don't know if that's enough to save it tho

@DestructibleWatermelon x is not allowed

Destructible Watermelon

dam

1:13 AM

the a in eval is also bad

This might actually be hard, eh?

h is bad

Destructible Watermelon

can you use parens for import?

p in import is no good

I know you can use __import__('name')

Welp

Anyway, will post later today, should be fun.

1:15 AM

Yeah might be pretty fun

I will try my best to solve it in python

Christopher Peart

youtube.com/watch?v=DV0TKAdEWAQ yass must do

Destructible Watermelon

@ChristopherPeart but you might break your angles

Christopher Peart

My angles?

Destructible Watermelon

look at the comments

AFAIK everyone here has seen Tomato?

Christopher Peart

1:19 AM

What?

docs.google.com/document/d/…

Help me design an esolang

@WheatWizard I know, I'll allow runs like that, but at a 10-byte penalty each.

So Java isn't completely invalid, just even more awful than normal.

What type of runs?

Christopher Peart

@wat Ok

I think it would be best to just disallow them

1:20 AM

4 or more in a row of 0 or 1 in binary representation of the code.

I do want regular langs to be able to at least participate.

I'm thinking either 10 byte penalty each or you can make a maximum of 3 such runs in you code.

If you are going to weight them down like that they might as well be banned imo

I am really not a fan of bonuses or penalties

But I don't want to eliminate all the langs.

The left parenthesis is banned... except before non-ASCII

My point exactly.

Also, curly brackets

Destructible Watermelon

1:24 AM

@JanDvorak dam

hey could you use brackets?

[thing][0]?

%r[fuu] is still valid

10 bytes is enough that avoiding the runs as much as possible will be optimal in almost all cases, but it's not so bad that being forced to have one insta-disqualifies you.

Destructible Watermelon

doubtful...

Ruby is out because I need either some whitespace, a left curly or "p"

... or a left pointy, also dead

Yeah, I'm going add in the penalty.

1:29 AM

don't forget to sandbox

Destructible Watermelon

"easier" than only even bytes

@ConorO'Brien I've mostly worked it out here.

still don't forget to sandbox

I'm fairly confident in my writing skills.

so was I

1:31 AM

Nice to get feed back on the bonus

Having determined that completely banning the runs prevents like all the langs from participating, I have opted to allow runs with the penalty.

Nah, Brainfuck is still completely unrestricted, and not a terrible weapon of choice

... if you can do with just one memory cell, that is

Yeah, but it's Brainfuck. It's incredibly long anyway.

@JanDvorak That is also an issue

A dialect should cut it

Destructible Watermelon

can you use > and ^?

1:38 AM

If the only solutions are in obscure esolangs and BF dialects, that's not very fun, is it?

@DestructibleWatermelon both bad

@Pavel isn't that par for all code golf? :-)

@Pavel Would WSF work?

HAHAHAHAHANO

@Pavel What other type of fun is there?

CR, NL, Tab, and Space are all blocked.

@WheatWizard But then you can't write a brain-flak solution

Destructible Watermelon

1:40 AM

@Pavel slightly rude

True

CMC: given N, find the closest divisor of N to sqrt[N]

Sorry.

fuck4 is free to go with no restrictions

@ConorO'Brien OOOH I've already done this in Brain-flak

1:41 AM

I have an idea

Let me find it

I can make a WSF derivative called MNOfuck

fantastic! :D

@wat Now that you know that the challenge will exist, creating a lang for it would violate a standard loophole.

No

It only has to be after the challenge is posted

1:42 AM

That's not what the loophole says

using knowledge about a challenge to be posted is also a loophole

That would be a different loophole

and is generally being a jerk

Destructible Watermelon

it has the same issues as making it for the challenge

skirting loopholes is, by itself, a loophole

1:44 AM

53

A: Loopholes that are forbidden by default

Using prior knowledge to circumvent other loopholes In particular, gaining an unfair advantage by inventing new languages for future challenges that are being sandboxed, discussed in chat, are your own, etc. For example, creating a language that solves a task specified in a sandboxed post with ...

You can read it in the onebox, no need to even open the link.

@ConorO'Brien I misremebered I did not write that code

... yet

oh lol. good luck XD

github.com/dkudriavtsev/mnof

CMC: calculate Sqrt[n] without builtins

Using Mathematica's Solve is cheating

@Pavel I have written that code

1:47 AM

I only clicked the "clone/download" link because I misread it as "close"

x=>x**.5

@wat Dude, revert that commit, it won't work.

@Pavel what do you mean?

It's a separate repo

Dude, revert that fork, it won't work.

Oic, It's just that it still says Whitespace in a lot of places.

@Pavel Brain-Flak

1:48 AM

oh no

Where does it say whitespace?

The README

Fine, not "a lot of places"

One place I found so far.

OK, fixed everything and made it actually work.

It uses MNO instead of mno now

never mind still wont work

Destructible Watermelon

@WheatWizard nice!

@WheatWizard Very good, yes.

@Pavel define builtin

1:54 AM

OK try this

github.com/dkudriavtsev/qrsf

@ConorO'Brien A function that computes x^n, where x is a parameter and n is a real number (which may be a parameter)

can we use our langs square function?

No

meh

does it have to work for non-ints

Nope

1:57 AM

*~inv

J, 5 bytes

What is that doing >_>

inverse of reflexive multiplication

Whatever, fine. I GTG.

lol bye

Destructible Watermelon

isn't reflexive multiplication x^2 though?

1:59 AM

it is, but it's not a builtin

* is multiplication, ~ is reflexive

Destructible Watermelon

k then

Time to whip up J's fixpoint function

I just answered in J >_>

Yeah... the inverse function approach is the easy way

fix point of x=>(x+n/x)/2 is more fun, though

2:14 AM

@flawr pls why do you have a ticker in the matlab room

;-;

@WheatWizard why'd you "looks ok" this?

it's a bad answer, completely ungolfed

Yeah its bad but I don't think ungolfed answers should be deleted, especially if its someones first time on the site.

I've downvoted but I didn't vote to delete

How should I name my restricted-source challenge?

"Run of three, let them be. Run of four, run for the door!"

@WheatWizard It's a violation of site rules.

Do include the "4-warned" pun

2:20 AM

Valid characters of length N

@GEOBITS WELCOME BACK! :D

I'm not back

oh

Well, I mean, kinda

Now you are

@ConorO'Brien I know. But I don't have to vote to delete everything that is violation of rules

2:20 AM

But not fully

He was "back" yesterday

Welcome back again

well, good luck with whatever!

I was forward yesterday

@WheatWizard I think you replied to the wrong person

2:21 AM

I still don't have my desktop though :/

@ConorO'Brien Sorry

@JanDvorak Even given that brilliant idea, I still can't think of a good name to communicate the idea of the challenge.

be four-warned this challenge is hard

Not a good title, but it might inspire you

@ConorO'Brien Doesn't seem to work, seeing as how it includes < in it.

@Pavel o_O

2:23 AM

run-length-limited code to detect run-length-limited code

@Pavel I might have all the pairs that don't work

Without being excessively boring >_>

Try this one

That looks better

I'll include a link in my post

wait let me revise it lol

2:26 AM

K

Try it online!

Destructible Watermelon

2:38 AM

too bad it gets truncated if you do more than two...

2:59 AM

well yeah
