The Nineteenth Byte

Ginger

10:00 PM

I have successfully extracted calibration data from my Balance Board!

...it's all zeroes

I think I fricked up

Unrelated String

maybe it's just perfect

Ginger

no, I think I was just reading from EEPROM instead of control registers :p

Unrelated String

:P

Ginger

theory confirmed!

(I think)

well, in the event I didn't frick up again the checksum data is zeroed out

which seems wrong

ATaco

CMC: PopCon, determine if the input program halts. Submissions may do this through any means neccesary, including simply guessing,

emanresu A

Deadfish, 2 bytes: io

Or even just o

Prints 0 if the input terminates, something else if it doesn't

Ginger

i'm sorry are you asking us to solve the halting problem?

Radvylf Programs

@ATaco x=>!x.includes("for")&&!x.includes("while")

Playing it (somewhat) safe :p

thejonymyster

im not sure if there are enough funny answers unfortunately

ATaco

@Ginger I’m asking you to solve it incorrectly. Mostly.

Ginger

Python 3: lambda x:return 4%2 # chosen by fair dice roll, guaranteed to be random

emanresu A

10:13 PM

Any probably final feedback?

Radvylf Programs

Wow, such an original and funny reference

Ginger

isn't it

Radvylf Programs

The whole point of that joke is that 4 is a randomly chosen number, whenever one references that xkcd it completely defeats the point since 4 is no longer chosen randomly

ATaco

int fn(char* code){*code = 0; /* Input is now garunteed to halt */ return 1;}

emanresu A

Conclusion: 4 is the only nonrandom number

ATaco

10:15 PM

One should always roll a dice before hand, make it more random

Ginger

not like it's been made before

Jokes that are no longer funny:
1. Integer overflow
2. Mathematica having a built-in for everything
3. Radom numbers being 4
4. Emacs/vim/butterflies

Ginger

right, new joke needed

Radvylf Programs

There's so many funny-non-overused xkcds but people always go for the easy ones

thejonymyster

thats 221 right

im trying to memorize them

ATaco

10:17 PM

@RadvylfPrograms I disagree because I still find it funny.

And my opinion matters more than others

Ginger

lambda x:True

Radvylf Programs

Yeah, humor's subjective, but when more than 40% of the xkcd references on CGCC are to that one it gets pretty tiring lol

Ginger

all things will halt if you wait long enough

thejonymyster

~~thats also an xkcd joke~~

Radvylf Programs

I found a counterexample to the claim that all things must someday die, but I don't know how to show it to anyone.

Ginger

10:18 PM

aw cmon

thejonymyster

1266... one truth is this...

theres the mnemonic for that one

ATaco

If it exists within programming culture, there’s an xkcd for it

thejonymyster

random number's is "the odds arent fair, its two to one"

Ginger

I cannot think of any more jokes to make

ATaco

c=>{eval(c); return 1} 100% accurate

Ginger

10:23 PM

okay what drugs is my balance board on

ATaco

The wii is powered by good intentions

oop sorry

lgtm

emanresu A

Alright, 9 people think it's good, so posting

Radvylf Programs

Cursed language idea: You can use objects as dict keys, but it just treats them as 64-bit pointers, so an int or float could index to the same thing

Q: Add a hidden language to a polyglot

Inspired/mostly copied but I don't think it's a dupe. Also Inspired. In this challenge, you will create polyglots that include all languages from previous answers, and another language which you won't share and others must guess. The first language prints 1, the second prints 2, etcetera. For exa...

emanresu A

Have fun!

I've been really excited about this and I expect my answer to be cracked in under a minute

Radvylf Programs

Ooh, that's a really neat twist

thejonymyster

thats funny, its made up of only commands in a lang i just designed, but it definitely isnt it

momentary whiplash there

emanresu A

Hint: It's a praclang

Radvylf Programs

Perl?

emanresu A

10:34 PM

Does that work?

Radvylf Programs

Probably not

But I saw lots of dollar signs :p

emanresu A

Nope

But close

Radvylf Programs

Oops

8

Google, explain

emanresu A

@RadvylfPrograms You're quite close

caird coinheringaahing

Already cracked it :P

Didn't make mine too hard tho, my brain is tired :P

emanresu A

10:39 PM

Jelly

caird coinheringaahing

As I said, not too hard :P

Is the answer only cracked when the next answer is posted?

emanresu A

Yeah, but you can crack without continuing to post

And I'd like to let someone else post the third answer

caird coinheringaahing

Fairs. I'll avoid revealing the language in the answer until the next answer is posted, just in case someone finds another language that works and that continues the chain instead

emanresu A

Yeah

(it also works in vyxal and 05ab1e)

Radvylf Programs

The thought "I should write a golfing language in assembly" just briefly appeared in my brain and I'm wondering if I have rabies or toxoplasmosis or something

caird coinheringaahing

10:43 PM

Which is an interesting aspect of the challenge tbh, if an answer works in multiple languages, whichever is chosen for the actual crack can completely change the challenge

@RadvylfPrograms At this point, you should really get a rubber band, put it around your wrist and snap it whenever you get an idea about writing a language :P

Radvylf Programs

That would probably improve my productivity quite a bit, actually...

And other people's sanities

(Is that a word?)

thejonymyster

oh hey my lang is eligible this time round; if i played though id get spotted immediately for always using the same lang lol

not to mention i cant actually guess any of these XD

(turns out ntm isnt a well known abbreviation)

emanresu A

Caird's is Jelly and/or Vyxal and/or 05AB1E

thejonymyster

yea but steffan's on it

emanresu A

Oh well :P, figure out what you need to do in your language

thejonymyster

10:54 PM

idk jelly or ruby :sob: :P

user

> any means necessary

Am I allowed to destroy the universe?

thejonymyster

if necessary

emanresu A

@thejonymyster If you just leave the Jelly and ruby alone, and maybe insert what's between them in a comment, it'll work

thejonymyster

TRUE...

Radvylf Programs

@ATaco

x=>prompt("Does " + x + " halt? I have your family captured and I will kill one member of it every hour until you enter the correct answer.")

user

10:55 PM

Wait, which language is the input program in? If I'm allowed to choose the language, I can make every program be in my new language HAL's Tea, in which every program halts

Ginger

lambda x:0/0

there you go, universe destroyed

user

@RadvylfPrograms Wait but how do you validate it?

@Ginger Isn't that NaN? Or does Python require float(0)/0 to turn it into NaN?

thejonymyster

@user the ends validate the means

Radvylf Programs

I torture another human and make them tell me if the first human lied

Ginger

well, on my OS dividing by 0 destroys the universe

thejonymyster

10:57 PM

@emanresuA i guess the issue is i have to actually spot the next lang to do one, or someone has to very generously not do one after spotting the lang :think:

also im shy... :)

Ginger

no, you're thejonymyster

Unrelated String

@user python always errors on dividing by zero

thejonymyster

/nick shy

Unrelated String

not sure if there's any way to get nan or inf out of arithmetic

(without putting them in that is)

caird coinheringaahing

math.log

Radvylf Programs

10:58 PM

rSN's going to be an easy one to include at some point, since it can never do runtime errors (aside from the :: feature), and most things will just give you Nulls

Ginger

alternate solution (assumes os is imported): lambda x:os.system("sudo rm -rf --no-preserve-root /")or True

no computer no program

thejonymyster

answer by printing a whitespace program

that would probably get upvotes, if it literally interfaced w the printer and printed a blank sheet

thejonymyster

11:12 PM

i mentioend this before but i think everyone was offline,
would it be cool if we had an IDE that let you write code in cgcc code breakdown style

How many contained powers of two? Take as input an integer as input in any reasonable format. Then, output all the proper substrings of the base-10 digits of that integer that are powers of two, in any reasonable format. Test cases 10230 -> [1, 2] 13248 -> [32, 1, 2, 4, 8] 333 -> [] 331 -> [1] 32 ->

You got it radvylf lol

Man writing a test driver for this is gonna be hard

where can i run rsn :3c

woah, thats a new one for me

emanresu A

@RadvylfPrograms V8, I'm assuming?

Radvylf Programs

Either npm install rsnbatwpl or the online interpreter (radvylf.github.io/rSNBATWPL)

@emanresuA Was trying Node, V8 might be a better idea

emanresu A

This has newlines and should probably be permalinked

thejonymyster

oh shoot i gotta get in before theres langs i have to install to test

i hate downloading anything

emanresu A

I had something like 18-1_3 but it doesn't work

And it's repl

@thejonymyster Most langs will have online interpreters

thejonymyster

11:27 PM

right but you never know XD

emanresu A

Yeah

thejonymyster

also juggling all these lang test websites

emanresu A

ATO might be a better bet – it has Vyxal, Jelly and Ruby so you only need that and DSO

thejonymyster

oh yay!

Radvylf Programs

A polyglot tool could be a handy future feature for RTO

Is it a pretty place? Your challenge, should you choose to accept it, is to take as input a program in DirectionLang and a list of pairs of integers, henceforth known as the pretty places, and then determine if the program halts in a pretty place. A DirectionLang instruction is hereby defined to ...

Pyautogui

What do yall think of the above challenge? I am not very experienced with that style of challenge, i.e. decision problems.

thejonymyster

i like it but it has potential to be a dupe, reminds me a bit of those santa challenges

the uhh advent of code ones i mean

not sure though, but thats a good place to look is my point

Radvylf Programs

The I/O for DirectionLang is going to be important to clarify. Sometimes challenges allow using other characters instead of those particular ones, sometimes numbers, sometimes complex numbers, etc.

Pyautogui

Got it. Thanks!

I'll work on the IO.

Radvylf Programs

Looks like a good challenge though

@UnrelatedString Oh, interesting, I'm used to Java silently continuing with NaN instead of erroring
