English, 3 bytes Bad — Mayube 15 mins ago

@Mayube I think the language you're looking for is Text

no, because the language is english.
If the language was french it wouldn't be `Bad`, it'd be `Mal`

@Mayube Text

hey how would people react if i used Text on a bunch of kolmogorov complexity challenges

Jan Dvorak

3:30 PM

There's already Bubblegum

@totallyhuman probably react by deleting your answers or at least flagging them

@totallyhuman with downvoted

@Mayube Carrot can output Bad in 3 bytes as well

can't post it anyway because Bad doesn't actually meet the spec :P

what about english

3:32 PM

@KritixiLithos Does carrot always start in insert mode?

yes, but in Carrot it's called caret-mode

solving the halting program in english

Read "Halting Problem" article in Wikipedia.
This program solves the halting problem.

@KritixiLithos link to GitHub? I'd love to read the docs

code-golf restricted-source

btw Carrot isn't TC yet, and so I am rewriting the interpreter to change all that

github.com/kritixilithos/Carrot

the docs are in the wiki

and the new interpreter is going to be written in node first

"covfefify a string" is now the 12th most upvoted question on ppcg

Actually it's the 12th highest scored

It has more upvotes than the one ranking just above it

:| how does covfefe beat upgoat downgoat

CMC: given e.g. 5, return 55555 (the given number will only be between 1 and 9) (repeat n n times)

4:18 PM

also, you must return a number, not a string, and you must use integer arithmetic

(Retina etc. is banned from this challenge for obvious reasons)

@Phoenix yes

@Mayube FOG: g

can't remember which language has a 1 byte builtin for this

@Mayube Duplicate

which is the one that literally uses a unicode goat?

as it's builtin

@Phoenix wait what :O

@LeakyNun Braingolf, 39 bytes ....91+8>[.]<*<+<,>**<+<,>***<+<,>****+

Does a language exist which is like BF but where each cell on the tape is a different stack?

stack or tape?

Tape and stack

So you've got an infinite number of stacks

@BetaDecay That perfectly describes my very poor knowledge of Braingolf

4:32 PM

*Stack stack flashbacks*

@BetaDecay this is a planned feature for Carrot (but slightly different)

even better idea: A tape of stack of tape of stack of tape of ...

@ETHproductions eh kinda, Braingolf does use a stack-stack, but isn't much like BF

oh, ok

@KritixiLithos Even better: a sheet instead of a tape (i.e. you can move up, down, lefy and right)

4:35 PM

Side question: Is there a BF-based language that's on a sheet instead of a tape?

You're getting closer and closer to Microsoft Excel

Is that a bad thing?

Whait nvm yes it is.

Whait = wait what?

That's excellent enough I'm not editing that

4:38 PM

Actually

Here's a better statistic

"covfefify a string" is the 3rd highest scored code golf question

Jan Dvorak

@totallyhuman I never really had a faith in humanity anyways...

@BetaDecay that's what my idea was (I did say slightly different) :D

it's going to use Vim's hjkl for movement

the reason is that Carrot sucks at storing lots of data

@BetaDecay I believe stackcats does that

@ETHproductions I definitely remember seeing that on esolangs but I forget the name

4:58 PM

@Qwerp-Derp haha sorry, not yet. I'll probably be working on that today

Perfect HNQ top 3!

@DigitalTrauma No?

fun fact: part of the reason I joined PPCG was seeing a lot of PPCG posts come up on HNQ. This eventually convinced me that PPCG was not just a place where old-timers gather together to code a game of golf, so I joined it

HNQ can vary

@BetaDecay In Noether, are there only the five functions, or are the rest undocumented?

~~ಠ_ಠ in JavaScript Array.map ignores undefined~~ Wait no it doesn't

How many countries have you been to?

define "been to"

IDK 24 hours there?

@Laikoni There?

Or 12+?

I'm not sure

5:42 PM

I've been to the edge of Canada once (Niagara Falls), but I didn't cross over so I suppose that doesn't count

@ConorO'Brien Oh cool

@ATaco ok this typing userscript is awesome

I've been to Vancouver once. I only spent 20-ish hours there, so I'm not sure if that counts

I'm counting it though

@ConorO'Brien ikr :D

@ConorO'Brien Agreed. :)

@DJMcMayhem I'd say "been" means "stayed there", like, you haven't "been" to a country if your plane passes over it

5:44 PM

Stayed there overnight?

What if you only go into the airport?

Ørjan Johansen

I resolved my current "can't comment on a deleted answer" problem by commenting on a completely different answer by the same person. Let's see how much that gets me "shouted at".

hm

I'd think not

Now states... I think I've stayed in 6

If airport counts, I've been to 8

I'm really not very well-traveled

5:45 PM

I've been in... I think 3 states

But I'm not from the U.S.

@DJMcMayhem don't think stopover counts

I've been to 17 states

@ATaco ^^

Yeah, I had the same thing lol

5:47 PM

the PPCG userscript doesn't seem to work for this chatroom

@ConorO'Brien They're undocumented as of now. I'll see if I can do it now

Maybe @BusinessCat has the userscript installed twice (Greasemonkey + Tampermonkey)

@EriktheOutgolfer Yeah, I don't think it does either. So I only count 5

I'm not sure of a good formatting method for listing overloaded functions

Umm I certainly don't but I have no idea why that's happening

5:48 PM

Erik the Outgolfer and Erik the Outgolfer are typing.

really?

@EriktheOutgolfer Wait, did you see that? O_o

no

I only have Tampermonkey

ah ok

> Business Cat is typing.

only appears once here

5:49 PM

this is cool

i am typing

@EriktheOutgolfer Now I only see it once as well, it was just that once or twice that it happened

maybe @BusinessCat removed the second copy...but you can't have two copies of a userscript!

or someone haxed

I had another userscript that I made running, but after you said that I turned it off

Maybe there really were two BusinessCats typing...

5:50 PM

I don't see how it would mess it up but you never know

@KritixiLithos you didn't appear

@BetaDecay no rush :)

because I don't have the userscript

I can tell

@KritixiLithos you must install it :P

5:51 PM

Hey, it doesn't tell you when you are typing anymore. That's nice

do you have the extension?

no

@MDXF what

wow he's alive!

maybe update it?

6:10 PM

@Okx it says that Conor is typing for a creepily long time

really? xD

btw if you think it invades your privacy you can disable it but you must have all taco scripts installed

;)

@ConorO'Brien People thought you were typing something huge

Or sleeping on your keyboard

oh no I just left a space in the textarea

what?

wait leaving a space without typing is considered typing?

6:13 PM

apparently so

but it was intentional right?

> :37895106 what

true he really left a space in

@ATaco huge problem should be fixed, leaving text in textarea apparently means typing at the moment

@DJMcMayhem How can you configure Vim so that Left/Right go to the previous/next line?

Like how it works in any other text editor.

@ATaco XSS is possible with your userscript

Did someone actually XSS it to bork the entire screen?

At least script seems to not work, which is a good thing, but totally changing the stylesheet is still possible

@TuxCopter Which one is that?

@Phoenix The I am typing userscript

It's really really really easy to abuse

@TuxCopter share with the class

8:37 PM

?

proof of concept?

Oh

wait

if your name has html in it i guess

var ws = new WebSocket("wss://a-ta.co", "typing");
ws.onmessage = function(msg) {
    var data = JSON.parse(msg.data);
    if (data.action == "getDetails") {
        ws.send(JSON.stringify({action: "setUserID", data: 1}));
        ws.send(JSON.stringify({action: "setUserName", data: "Hi"}));
        ws.send(JSON.stringify({action: "setRoom", data: 240}));
        ws.send(JSON.stringify({action: "startTyping", data: undefined}));
    }
}

oh you mean if you manually send data on the socket

gotcha

that'll do it
