whats happening!?!?!

ACuriousMind

@AccidentalFourierTransform Yeah

David Carlisle

@AccidentalFourierTransform just popped in to see if I could make sense of a conversation that had drifted into the tex.stackexchange chat:-)

Emilio Pisanty

y'all want to do this sort of unholy hacking, do it on the tex.se chatroom

Joseph Wright

@DavidZ There was a mention in the TeX-sx chatroom that something interesting was going on

Sir Cumference

@JohnRennie Not so much hacking as rendering it unusable (at least for people with ChatJax++)

AccidentalFourierTransform

5:00 PM

oh god Im so happy am a part of this

Sir Cumference

(like myself)

heather

@AccidentalFourierTransform yep =D

David Z

Ohh right... I forgot to rejoin that room

Bernardo Meurer

@JosephWright @DavidCarlisle We are working on breaking chatjax

We want help

Sir Cumference

All thanks to @BernardoMeurer for introducing everyone to \newcommand

Bernardo Meurer

5:01 PM

lol

Sir Cumference

Congrats, you broke the world

heather

@BernardoMeurer, please do try Ackermann

ACuriousMind

@AccidentalFourierTransform I was busy writing this answer so I didn't keep track on what's going on here and now...this, whatever this is

Secret

bernard is not the first guy who introduce newcommand to this chat. It is danielsank who first done that 1 years ago according to chat logs

David Z

@BernardoMeurer To be fair, MathJax is a fairly "crippled" version of (La)TeX. You can't break it too badly.

AccidentalFourierTransform

5:02 PM

@ACuriousMind who cares about Hamiltonians? were making history here

Bernardo Meurer

@DavidZ I HEAR A CHALLENGE

4

AccidentalFourierTransform

people will reference the mathjaxx apocalypse for centuries

ACuriousMind

I, for one, just deactivated MathJax for the time being :P

Sir Cumference

@DavidZ Look what you've done

Bernardo Meurer

@DanielSank LET'S BREAK IT

DanielSank

5:03 PM

What's going on in here?

heather

$\mathbb{SO}\; \mathbf{LET}\;\mathbb{US}\; \mathbf{CONTINUE}$

2

and break chatjax

@DanielSank madness, wonderful madness

Sir Cumference

@ACuriousMind Er, it still works

Secret

@DanielSank your \newcommand result in h bar being broken, lol

Bernardo Meurer

$\renewcommand{\mathbb}{\text{\Huge BREAK IT}}$

DanielSank

Et tu, @heather?

Sir Cumference

5:03 PM

@BernardoMeurer Oh god

David Z

I'm letting this happen on the assumption that people get bored of it soon enough

AccidentalFourierTransform

anyone knows how to code a while-do with mathjax?

heather

@DanielSank yep

DanielSank

@DavidZ so naive

AccidentalFourierTransform

a simple while(1) \partial should do the trick

ACuriousMind

5:04 PM

@SirCumference wat? I meant I just deactivated my MathJax rendering bookmarklet thingy.

Bernardo Meurer

We need to somehow make ackermann in chatjax

Sir Cumference

$\newcommand{\partial}{\definecolor{energy}{RGB}{114,0,172} \definecolor{freq}{RGB}{45,177,93} \definecolor{spin}{RGB}{251,0,29} \definecolor{signal}{RGB}{18,110,213} \definecolor{circle}{RGB}{217,86,16} \definecolor{average}{RGB}{203,23,206} \color{energy} X_{\color{freq} k} \color{black} = \color{average} \frac{1}{N} \sum_{n=0}^{N-1} \color{signal}x_n \color{spin} e^{\mathrm{i} \color{circle} 2\pi \color{freq}k \color{average} \frac{n}{N}}}$

Hmm

$$\frac{\partial \rho}{\partial z}=-\rho G\frac{M}{z^2}\cdot\frac{m}{V \rho nRT}=-G\frac{M}{z^2}\cdot\frac{m}{V nRT} \tag{4}$$

Emilio Pisanty

oooooh, look at this

Sir Cumference

Some smart guy...

heather

MathJax documentation

Sir Cumference

5:05 PM

Uh oh

DanielSank

Watching this all with chatjax off is amusing.

heather

@SirCumference, what this time?

Sir Cumference

Someone destroyed \newcommand

heather

@SirCumference, uh...you?

Bernardo Meurer

@SirCumference Dammit

Sir Cumference

5:05 PM

@heather Nope

Okay folks

what happened?

I will kill the fun

@BernardoMeurer Probably because someone did \newcommand on \newcommand

Bernardo Meurer

$\renewcommand{\newcommand}{\text{GOODBYE}}$

Sir Cumference

5:06 PM

@AccidentalFourierTransform You suck... XD

DanielSank

@BernardoMeurer lolol

heather

$
MathJax.Hub.Config({
TeX: {
Macros: {
RR: '{\\bf R}',
bold: ['{\\bf #1}', 1]
}
}
});$

oh, wait

what am I doing?

Sir Cumference

Sigh. $\newcommand{\text}{\text{test}}$

Bernardo Meurer

PEACE HAS BEEN RESTORED

(in part)

DanielSank

@heather ahahahaga

heather

5:07 PM

@BernardoMeurer, has it?

Sir Cumference

@BernardoMeurer You monster

heather

what has happened

Bernardo Meurer

$\newcommand{\newcommand}{\text{quit trolling}}$

LOOK

I broke it badly

OH

I KNOW HOW TO BREAK IT

Sir Cumference

$\renewcommand{\newcommand}{\text{no}}$

heather

@BernardoMeurer DO IT!

DanielSank

5:08 PM

I need to get my laptop so I can see what thus looks like with chatjax on.

Bernardo Meurer

WE can make a newcommand/renewcommand Loop!

Sir Cumference

@BernardoMeurer Oh god

Bernardo Meurer

Somehow

heather

@DanielSank try not to die!

Sir Cumference

Stop

$\newcommand{what}$

heather

5:08 PM

@BernardoMeurer YES!!

$how\,should\,we\,do\,this$

Sir Cumference

$\renewcommand{\rho}{\definecolor{energy}{RGB}{114,0,172} \definecolor{freq}{RGB}{45,177,93} \definecolor{spin}{RGB}{251,0,29} \definecolor{signal}{RGB}{18,110,213} \definecolor{circle}{RGB}{217,86,16} \definecolor{average}{RGB}{203,23,206} \color{energy} X_{\color{freq} k} \color{black} = \color{average} \frac{1}{N} \sum_{n=0}^{N-1} \color{signal}x_n \color{spin} e^{\mathrm{i} \color{circle} 2\pi \color{freq}k \color{average} \frac{n}{N}}}$

Bernardo Meurer

If we newcommand renewcommand to being newcommand and then newcommand is already renewcommand to renewcommand

Sir Cumference

$$\frac{\partial \rho}{\partial z}=-\rho G\frac{M}{z^2}\cdot\frac{m}{V \rho nRT}=-G\frac{M}{z^2}\cdot\frac{m}{V nRT} \tag{4}$$

Goddammit

DanielSank

@heather RIP my laptop

Bernardo Meurer

it should brainfuck mathjax

AccidentalFourierTransform

5:09 PM

$\rho$

heather

@BernardoMeurer okay

$\rho$

Sir Cumference

@AccidentalFourierTransform Someone broke it

AccidentalFourierTransform

you killed rho

heather

$\mu$

AccidentalFourierTransform

"someone"

heather

5:09 PM

$\partial$

Sir Cumference

@AccidentalFourierTransform Nah, \newcommand is broken

Bernardo Meurer

$\renewcommand{\mu}{\text{STAHP}}$

heather

you broke partial, too

Sir Cumference

$\mu$

Bernardo Meurer

$\renewcommand{\partial}{\text{STAHP}}$

heather

5:10 PM

i'm literally waiting for my computer to crash

Sir Cumference

$$\renewcommand{\partial}{\frac{\partial \rho}{\partial z}=-\rho G\frac{M}{z^2}\cdot\frac{m}{V \rho nRT}=-G\frac{M}{z^2}\cdot\frac{m}{V nRT}}$$

$$\frac{\partial \rho}{\partial z}=-\rho G\frac{M}{z^2}\cdot\frac{m}{V \rho nRT}=-G\frac{M}{z^2}\cdot\frac{m}{V nRT} \tag{4}$$

@SirCumference Uh oh

DanielSank

@DavidZ I have calculated the cross section for Heather and Bernardo to create a black hole in the Stack Exchange servers with what they're doing. In the name of science I ask that they be allowed to proceed.

Bernardo Meurer

@SirCumference Oh wow

David Z

@DanielSank You'll notice I haven't stopped this the whole time I've been sitting here ;-)

Bernardo Meurer

@SirCumference YOU BROKE IT

SUCCESS!

Sir Cumference

@Secret wtf

Bernardo Meurer

@Secret Is on a whole other level

Emilio Pisanty

who made mathjax do the little gray box at lower right?

this thing is properly broken now

heather

$\def\x{\x} \x$

@Secret what did you do?

Sir Cumference

Well, gotta go

heather

5:12 PM

$\newcommand\def\x{\x} \x$

Sir Cumference

@heather He put a period at the end of all that

Bernardo Meurer

@Secret Did you divide by 0?

2

Secret

Don't forget, lovecraftian creature like to inject a lot of insanity on me

heather

@SirCumference see you around

Bernardo Meurer

If only we could do loops here

heather

5:13 PM

okay, wait, I've got it

docs.mathjax.org/en/latest/options/TeX.html

read under the last two headings

Bernardo Meurer

It's broken, chatjax keeps reloading endlessly

AccidentalFourierTransform

$\x$

heather

$MathJax.Hub.Config({
TeX: {
MAXBUFFER: 10000*10^24
}
}
});$

$\def\x{\x aaa} \x$

ack

AccidentalFourierTransform

MathJax.Hub.Config(please work again);

David Z

@heather That's Javascript

It doesn't work in chat

ACuriousMind

5:15 PM

@AccidentalFourierTransform lol

heather

@DavidZ darn it, foiled again

Secret

mthjax really need a "go back to defaults" command

David Z

@Secret F5

DanielSank

@Secret just reload the script

And the page

AccidentalFourierTransform

can we just delete this chatroom and get a fresh start

?

Secret

5:17 PM

once the chat scroll past the newcommands, the chat will go back to normal

heather

$\renewcommand{\rho}{\definecolor{energy}{RGB}{114,0,172} \definecolor{freq}{RGB}{45,177,93} \definecolor{spin}{RGB}{251,0,29} \definecolor{signal}{RGB}{18,110,213} \definecolor{circle}{RGB}{217,86,16} \definecolor{average}{RGB}{203,23,206} \color{energy} X_{\color{freq} k} \color{black} = \color{average} \frac{1}{N} \sum_{n=0}^{N-1} \color{signal}x_n \color{spin} e^{\mathrm{i} \color{circle} 2\pi \color{freq}k \color{average} \frac{n}{N}}}$

o c***...

heather

(entered with mathjax off)

if you'd like i can delete it

Secret

lol

Bernardo Meurer

God work today folks

Science has advanced

Secret

5:19 PM

Indeed indeed

heather

indeed

so...we come back to this another day? (in the name of science, of course)

DanielSank

@BernardoMeurer publish

AccidentalFourierTransform

today mathjax, tomorrow quantum gravity

one step at a time

My favorite beer tastes weird

heather

$\valign{\halign#\cr!$

David Z

@heather no it doesn't, and this is why if you really want to "break" things, you don't use MathJax

heather

$\def\a{a\a}\a$

@DavidZ that sounds like a challenge.

@DavidCarlisle That's probably accurate.
