new question! new question!

...how are polyglots even possible >_>

Mendeleev

Similar syntax

Downgoat

@totallyhuman comments and strings

Mendeleev

For example, print("Hello, world!") is a polyglot(-ish? It doesn't print newline in ruby) between Ruby and Python

totallyhuman

it is?

i thought it was puts

Downgoat

9:07 PM

@Mendeleev and cheddar, and VSL, and JS, and Swift

probably a ton more

Mendeleev

@totallyhuman Puts is with newline.

Also, puts("Hello, world!"); is a polyglot between Ruby and C

can someone come onto OPPCGMCS and rate my base design ;-;

MD XF

echo "Hello, World!" is a polyglot between like every shell ever

Mendeleev

And DOS

totallyhuman

o0 pyth has a newline function

Jarko Dubbeldam

@Mendeleev Works for R too :)

Luis Mendo

9:12 PM

I have two downvotes here... suggestions for improvement, anyone?

Mendeleev

I think something like this would work:

Downgoat

@Mendeleev and VSL and C++ :P

Mendeleev

#define a b

Scripting style languages usually use # comments.

then use those defines to build replacements

@Downgoat Most of them

MD XF

@LuisMendo Huh, looks fine to me, +1. But iuncluding

Q: Count like Chuck Norris

As is well known, Chuck Norris counted to infinity. Twice Besides, Chuck Norris can count to infinity backwards. Also, although perhaps less known, Chuck Norris can speak a little Spanish in addition to English. The challenge Write a program (or function) that can be run in two diff...

Luis Mendo

@MDXF Thanks. What to you mean by iuncluding?

MD XF

@LuisMendo Oh you had a typo but I fixed it

Luis Mendo

@MDXF Ah, I see. That's why I couldn't find it :-D

MD XF

Haha yeah

Luis Mendo

I hope the downvotes were not for that!

MD XF

9:18 PM

It's funny how I notice others' typos real quick but I can never spot my own :P

Luis Mendo

Yeah, that happens

MD XF

¯\_(ツ)_/¯

Man I'm learning so much about Rubik's Cubes while working on Cubically

Jaggler3

I can't find an old challenge I golfed :(

I had to output a square with a width of the input number and the number as the edges

It was like this one but a little different codegolf.stackexchange.com/q/98866/68923

Lol found it

> Don't use The Nineteenth Byte as a dumping ground for your thoughts or actions. Consider whether a topic would be relevant to others before talking about it. We're here to have discussions, not to listen to someone's stream of consciousness.

(I think this is applicable in this case. It may not be, but even if it is, just good for future reference)

Jaggler3

I didn't mean to I didn't know if anyone here might recognize the challenge or not but I will keep that in mind

MD XF

9:29 PM

Thanks :D I wouldn't have said anything if you'd phrased that as a question, e.g. "I had to output a square with a width of the input number and the number as edges. Does anyone know what challenge this might be?"

I had to be corrected a few times when I first started talking here haha

Jaggler3

I will look through that thanks

MD XF

People who're helping with Cubically: Do you think R2 or B2 or L2 or F2 is a better algorithm to get 78 on three faces combined?

Downgoat

Quetion: is this not a function: f(x)=x^(1/2) becomes for one input there can be multiple output?

MD XF

@Downgoat s/est/et :P

Downgoat

shit sorry >__<

MD XF

9:40 PM

thank ya sir :P

@Downgoat holy sh*t

opls

You've said more lol

:|

shit you gotta get your game up

MD XF

heh this is the worst thing I've said

@totallyhuman -_-

Downgoat

9:43 PM

@MDXF opls

MD XF

@totallyhuman says you

@Downgoat Ay I linked to one time Dennis said it and the other time it was *'d out

totallyhuman

i haven't been here long enough

and if i was angery and hungary enough, sailors would be proud

MD XF

@DestructibleLemon ohhhh

Downgoat

@Phoenix we allow program puzzle but "do my homework kthxbai" is not program puzzle

Challenger5

You might be able to make a really broad cops&robbers challenge that covered every type of programming puzzle you'd ever want to make

But it would probably be closed as "too broad".

Downgoat

9:47 PM

@Challenger5 s/probably /

MD XF

> You might be able to make a really broad challenge.... but it would probably be closed as "too broad".

ಠ_ಠ

Downgoat

or actually: fpdw

Challenger5

At this point I'd probably start arguing about how the sandbox should be closed as "too broad", but that's pointless and it would make everybody hate me.

MD XF

@Challenger5 You're not wrong

Downgoat

@Challenger5 wat why how wat why how

totallyhuman

9:49 PM

ಠ_ಠ

how is the sandbox too broad ಠ_ಠ

Downgoat

Also the sandbox allows us to say "please try out the sandbox to iron out bugs" rather than "your challenge fundamentally sucks and it's not going to get anywhere"

MD XF

hehe I VTC'd (JUST KIDDING)

Downgoat

@MDXF @Dennis suspension-request

totallyhuman

ಠ_ಠ_ಠ

MD XF

@Downgoat (I was kidding)

Downgoat

9:50 PM

@MDXF but seriously don't do that

Challenger5

That's funny, it looks like the sandbox already has a close vote for "too broad"

MD XF

I'm not that stupid

trichoplax

@MDXF Please don't abuse close votes

MD XF

@Challenger5 oh gosh did someone else do that

Downgoat

@MDXF IIRC mods can see who CV'd so we'll see

MD XF

9:51 PM

You can also see CVs

totallyhuman

> close the sandbox as "primarily opinion-based"

MD XF

Go look at it yourself

2 mins ago, by MD XF

hehe I VTC'd (JUST KIDDING)

Downgoat

@MDXF sorry >_< I a word

MD XF

I a word ?

totallyhuman

i accidentally a word

god that's an old meme

MD XF

9:55 PM

that one?

totallyhuman

about 8 years old according to knowyourmeme

MD XF

Ugh Cubically hates the number 5

totallyhuman

MD XF

@totallyhuman that's not real, right? :P

totallyhuman

we would've found about it by now, wouldn't we have?

Hey @Adnan, could you explain this?

You're reading the file with the 05AB1E codepage as UTF-8, but your codepage contains some bytes that are notably not valid in UTF-8.

Which means it will just fail if your program contains any of those bytes.

llama@llama:...code/misc/ppcg126986norris$ python3 ../05AB1E/05AB1E.py -c poly4
Traceback (most recent call last):
  File "../05AB1E/05AB1E.py", line 3908, in <module>
    code = open(filename, "r", encoding="utf-8").read()
  File "/usr/lib/python3.6/codecs.py", line 321, in decode
    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xfc in position 9: invalid start byte

Case in point.

MD XF

@Doorknob llama@llama?

Challenger5

If I understand correctly, it has a mode for reading the file as UTF8, and one with the 05ab1e codepage.

Downgoat

@MDXF idk I think @Mendeleev was first to do

MD XF

@Downgoat You mean "idk I @Mendeleev was first to do"? :D

Doorknob

@Challenger5 Right. Notice how the one that reads "with the codepage" actually reads as UTF-8 first, for whatever reason. (See also the error above - -c is the flag that supposedly reads the codepage but actually reads as fake UTF-8 and then converts to real UTF-8.)

Mendeleev

10:02 PM

I don't know

Challenger5

I have no idea then. I guess all previous 05ab1e answers that use those bytes have been invalidated...

xnor

@LuisMendo I'm not sure, my other bounties have been for a specific goal. My thinking here was, I'm looking for better answers, but don't really know how to express what makes an answer better. And I don't want to limit to my future self from accepting some really good answer that's good in a way I didn't expect. So it's basically "what I like most", and saying that feels like I'm not really saying anything.

Doorknob

@Challenger5 Well, it's easily fixable in the interpreter. All the more reason to go through with Martin's recent campaign, I guess :P

Challenger5

Yep. Also, it looks like you could still pass it though command-line args if you had a terminal that used some other character set

Luis Mendo

@xnor My problem is that in this challenge I want to attract more answers (there are standard languages with graphical capabilities that have not participated), but they probably won't beat current winning answer in terms of bytes. So people may think "why participate, I won't get the bounty"

xnor

10:10 PM

@LuisMendo Hmm, I hadn't considered that people might default to assuming fewest-bytes for a bounty rather than whatever the bountier likes most

Challenger5

You could add it to the list of bounties with no deadlines?

Come up with some sub-challenge to get it to attract attention

Doorknob

@Adnan Anyway, here's a pull request that fixes that.

totallyhuman

brainfuck but with a grid instead of a tape

wait no i don't want to write another brainfuck derivative

Adnan

@Doorknob Ahh, you're totally right. That was a stupid mistake haha, thanks for the fix.

Challenger5

It's only a brainfuck derivative if you call it one.
If Brain&Chuck was called a "brainfuck derivative," no one would object.
You could call it "inspired by BF" or "in the spirit of BF".

Idea: protect the sandbox

user165474

Seriously, we need to suspend Community... Half of the revision history on Sandbox is Community removing the featured tag (which has been readded every time) and protecting the question (which I think is fixed now with a setting)

Challenger5

10:52 PM

So you want to protect the sandbox from being protected?

11:07 PM

@Downgoat @ETHproductions I found something interesting. In JavaScript, you can generate a custom error name quite easily with this: throw new DOMException("ohai", "CustomError"); This errors out with: CustomError: ohai

ASCII-only

@ConorO'Brien Not that interesting, you can do throw 'CustomError: ohai'; :P

Jaggler3

Is it worth posting an answer that doesn't work for all test cases?

Like works for 1 to 9 instead of 1 to Infinity

ASCII-only

@Jaggler3 Not really, unless it's from a language restriction

Just no insane limits like only work for n=0

hey do any of you guys wanna play spyfall?

Downgoat

@ConorO'Brien huh, that's interesting doesn't work with normal errors either. Though for me your example gives CustomError (DOM Exception): ohai

Conor O'Brien

yeah, it's really quite odd

fixed
