The Nineteenth Byte

This is surprisingly difficult to not use a bunch of if logic

Mr. Xcoder

@AdmBorkBork Which one?

AdmBorkBork

DJ's arrow string

Downgoat

@DJMcMayhem (haven't tested yet but) cheddar: s->(|>(s*2).len=>i->(' '*(i%s.len))+s.chars.cycle(i).fuse).vfuse

DJMcMayhem

V, 11 bytes: òMÄÙx$pÉ êl

And it makes me so happy that it's the shortest one so far XD

HyperNeutrino

@Mr.Xcoder f=lambda s:s and s+'\n'+f(s[1:])

Mr. Xcoder

4:01 PM

@HyperNeutrino I hate recursion anyway :(

Mayube

K I think this challenge is actually impossible in braingolf

HyperNeutrino

but I beat you so ha

Mayube

wait!

HyperNeutrino

f=lambda s:s and s+','+f(s[1:])

test -> test,est,st,t,

it includes the last one

totallyhuman

No I will not wait

You wait

Mr. Xcoder

4:02 PM

I don't really think about my CMC now, I'm focusing on DJMM's

DJMcMayhem

Would mine be a good challenge for main?

Step Hen

@DJMcMayhem Prolly

DJMcMayhem

I mean, it's essentially the same as this, just in a different direction.

Mr. Xcoder

@DJMcMayhem Yes, but might wanna sandbox it first

AdmBorkBork

Fixed version, 73 bytes

Mr. Xcoder

4:04 PM

@DJMcMayhem Then it would be a near-dupe, nah

DJMcMayhem

@Mr.Xcoder Ehh, I don't usually bother with the sandbox unless it's a complicated challenge.

I'm not really worried about making myself clear, I'm more just worried about dupyness

Step Hen

@DJMcMayhem Isn't that like all Sandbox does?

Mr. Xcoder

@DJMcMayhem It's kinda dupy

Mayube

Woo! I did it!

DJMcMayhem

Speaking of the sandbox, I'm planning on posting this later today:

4:05 PM

I think it's much of a dupe imo

DJMcMayhem

Does anyone have final thoughts?

Step Hen

@Mayube Did it take you four hours, like my Eureka moment did? :P

DJMcMayhem

I'm happy with all of it except for IO format. Not sure what to do there

@EriktheOutgolfer I agree. I'm not planning on posting it

Step Hen

@DJMcMayhem ATM you can't for example use JavaScript, right?

Mayube

@StepHen nope, about half an hour of doing various multiplication and division on the number 5 to try and make 65

DJMcMayhem

4:06 PM

@StepHen Why not?

totallyhuman

oh that might be a nice challenge for ,,,

DJMcMayhem

Because STDIN/STDOUT?

Step Hen

@DJMcMayhem Yup (pure JS not node)

DJMcMayhem

Hmm. OK

I guess that would probably also exclude vim ;_;

totallyhuman

what's ord('A') again

caird coinheringaahing

4:07 PM

@totallyhuman 65

DJMcMayhem

@totallyhuman asciitable.com

Step Hen

@totallyhuman right click -> inspect -> "A".charCodeAt(0) -> Enter

totallyhuman

@DJMcMayhem yes i know

just too lazy :P

65 or 97... hmmm

caird coinheringaahing

I got pinged by that, but didn't see it got edited and thought stealth pinging was back

totallyhuman

wait a minute

'Co2-c

Mayube

4:09 PM

Woo! Quite pleased with this one

totallyhuman

push "C", convert to ordinal, subtract 2, convert to character

DJMcMayhem

@StepHen How does this sound: Cops may choose any standard method of input and output for full programs. (not functions) However, they must reveal exactly which format (input and output) they are using. A crack is not valid unless it uses the same format.

Mr. Xcoder

@Mayube "Niladic division" is fancy

Mayube

@totallyhuman I hate you

totallyhuman

wut

Mayube

4:10 PM

Braingolf, 7 bytes: "C"2-@;

I spent ages getting my fancy answer working

Mr. Xcoder

@Mayube Your answer is great

totallyhuman

@Mayube #C..?

HyperNeutrino

wtf DJMM's CMC is harder than I thought in Jelly

Mayube

@totallyhuman # is in the disallowed chars

Step Hen

@DJMcMayhem That sounds better, ~~it's not code-golf right?~~

DJMcMayhem

4:12 PM

Actually, it is. Originally I had most safe answers, but Dennis pointed out that encourages quantity over quality

So now it's shortest safe answer, or longest time to crack

totallyhuman

ah

Step Hen

@DJMcMayhem That point doesn't matter as much as I thought, since it's the language-breaker's bytes and not the solution's bytes (right?)

Mr. Xcoder

@DJMcMayhem I have the first part:

Hello
 elloH
  lloHe
   loHel
    oHell

DJMcMayhem

@StepHen No, robber byte count is irrelevant. Only cop byte count

Do you think robber byte count should matter? I thought about doing something with that

Step Hen

@DJMcMayhem Right, I was thinking that console.log would screw it over, but since that would (probably) be in the robber area, it wouldn't make answers too long

Mr. Xcoder

Hello

     Hello

(self-message such that I can see the output ^)

Step Hen

@DJMcMayhem I think it's good enough - I doubt many mainstream langs will remain uncracked

Mayube

@totallyhuman why did you suggest ord(C) - 2 rather than ord(B) - 1?

DJMcMayhem

@StepHen Actually, I suppose for scoring, byte count has to be for both snippets, one and two.

totallyhuman

@Mayube 1 is disallowed

Mayube

oh right

Step Hen

4:16 PM

@DJMcMayhem Right, just make sure no one accidentally posts their score before it's cracked :P

Mr. Xcoder

@DJMcMayhem 30 bytes: Km+*" "d+>Qd<QdUlQjK;+*dlQQj_K.

Can most likely be golfed a lot ^

I have to go now, will come back soon

Step Hen

@DJMcMayhem does the first program have to not crash when given two numbers as input?

DJMcMayhem

The first snippet won't be given input, so it doesn't matter.

But it does need to finish executing regularly so that the second snippet is actually capable of running

Step Hen

@DJMcMayhem And it can output something (before the second snippet is attached), correct?

DJMcMayhem

So something like import sys; sys.exit() is not a valid first snippet since the second snippet will not actually be executed

I'll add that clarification

@StepHen Hmmm. I didn't think about that

I guess I don't see why not

Business Cat

4:23 PM

@HyperNeutrino I got it in 15 bytes, but I'm no Jelly expert myself

flawr

@Riker oh god

Step Hen

@DJMcMayhem One more question: can I have it so that the first snippet will crash if it does not have the two inputs?

HyperNeutrino

lol I haven't even gotten it yet

DJMcMayhem

@StepHen I'm not really sure I understand how/why it would do that. The first snippet is the breaker, the second snippet is the fixer, and then the adder. So as far as the first snippet is concerned, there is no input or any task (like adding) other than to mangle the language as much as possible

So TL;DR the first snippet should run without input

HyperNeutrino

uh rip apparently there's a serial arsonist near my area

Step Hen

4:25 PM

@DJMcMayhem OK, thanks :)

@HyperNeutrino if your computer melts, we'll be thinking of you

6 bytes is... bad comparing to other answers

tied with PHP?!

Xanderhall

what's wrong with being tied with php

PHP is great

Step Hen

@DJMcMayhem wait... does the second snippet need to work without the first snippet?

DJMcMayhem

4:30 PM

No

Step Hen

@DJMcMayhem This snippet must still correctly function even after running the first snippet. that scared me

DJMcMayhem

Hmm, I guess I could word that differently

Q: Shifting Caesars Shifts

DJMcMayhem

Is this rule strong enough?

> [Please reveal...] Any strange edge cases required for your answer to work. For example, only runs on linux, or requires an Internet connection. Obviously, this is slightly subjective, but if a cop has some extreme edge case that prevents it from being cracked, and then only reveals this after being safe, I consider this poor-sportsmanship. A potential robber should have all information necessary to crack your answer.

Step Hen

@DJMcMayhem A potential robber should have all information necessary to crack your answer. I think that gets the point across

DJMcMayhem

4:33 PM

But what if someone ignored that and said It's poor sportsmanship, but it's still valid

Step Hen

If they didn't provide everything required to run their second snippet, it's not valid imo

DJMcMayhem

Is that grounds for deletion?

Step Hen

If you put it in the spec, yes

up to you

If after revealing, and with the information provided in the answer as posted, you cannot reproduce their results, how it is valid?

DJMcMayhem

as posted meaning looking at it pre-crack?

Step Hen

@DJMcMayhem yes, if given the pre-crack info + the revealed snippet no one can reproduce it, how is it valid?

DJMcMayhem

4:37 PM

OK, that sounds good

Step Hen

@DJMcMayhem The second snippet is simply appended to the end of the first snippet, correct?

DJMcMayhem

Yep

Step Hen

and... can the second snippet output, then crash?

sorry for asking so many questions :P

DJMcMayhem

> This goes back to Please reveal any strange edge cases required for your answer to work... Your submission must contain enough information before being revealed to be reproducible after being revealed. This means that if your answer becomes safe, and then you edit in: Here's my answer. Oh ya, BTW this only works if you run it on Solaris, jokes on you! your answer is invalid and will be deleted and not considered eligible for winning.

AdmBorkBork

and you're a doody-head

DJMcMayhem

4:41 PM

@StepHen I don't mind at all. In fact, you've helped me solidify the spec a ton. I really appreciate it!

The second snippet can crash, sure. I'll clarify that

AdmBorkBork

lol, just got a support ticket to increase a server's D: drive from 40GB to 2TB

Step Hen

@DJMcMayhem would that be part of the information required to be shared or no?

DJMcMayhem

I don't think so

ckjbgames

Dang it

I'm trying to debug a program that uses CImg and I'm getting a bunch of linkage errors

HyperNeutrino

@AdmBorkBork the D: looks like a face

DJMcMayhem

4:43 PM

I'm more just hoping to avoid things like This only works on unpublished commit #7642 of this obscure Java second party compiler when ran on Solaris 3 32 bit with no more than 1.5 GB of ram.

ckjbgames

The site has me on question cooldown for 2 days

Damn it

AdmBorkBork

@DJMcMayhem That ... that seems excessively obscure, even for PPCG.

Step Hen

@AdmBorkBork Have you looked at the Sandboxed spec? :P

DJMcMayhem

It would basically be uncrackable

HyperNeutrino

mod-action-request convert-answer-to-comment codegolf.stackexchange.com/a/133084/68942

Step Hen

4:45 PM

@AdmBorkBork It's literally inviting answers like that, it just wants that ridiculously obscure information to be included

DJMcMayhem

Obscure behavior like that is fine (even encouraged), it's just that you need to know about it so that you actually make an attempt to crack it

@WheatWizard I'm planning on posting my C7R later today, so I just edited the spec a lot. Any thoughts on the new revision?

AdmBorkBork

No, I didn't. /shameface

HyperNeutrino

hey look a new user that's read through the help pages for once and knows about how the rep system works :D and is taking my feedback well for once :DDD

ckjbgames

FINALLY FIXED THE STUFF! YAY!

Step Hen

@ckjbgames fixed the stuff you have, celebrate you will

DJMcMayhem

Hehe

ckjbgames

@StepHen i successfully built my CImg application test

I'm working on the socratic badge, so I'll post the cop at 23:50 UTC, and the robber at 0:00 UTC. XD
