@0celo7 Well, everytime someone deletes something you keep asking what was deleted, and everytime someone says something you don't understand you keep asking even after being told an equivalent of "Don't worry about it"

@dmckee A few years back they uncovered a secret agent in some student groups here who had infiltrated them on the search for such a commietratorspy

0celo7

@skillpatrol I need to know what was deleted

I remember when you told me that

when did it happen, this needs to be something that they would have heard of

ACuriousMind

Oh...a few years back, I guess ~2006? I'm not sure

skill patrol

lol

0celo7

Lang might know about it

sometimes I have no clue what I'm trying to say

@Slereah Relevant hovertext.

ok

ACuriousMind

xkcd gets one-boxed, you don't need to post the image links. The one-boxing also makes the hovertext available in chat.

@ACuriousMind Will you play sc2?

0celo7

@ACuriousMind I know, I thought the image link did the same thing.

TIL.

ACuriousMind

@obe I currently don't plan to

Drop it.

And you people say I can't drop things.

skill patrol

You blow my mind sometimes pal

@skillpatrol Why

skill patrol

how is ONE person's opinion "you people say"?

This describes pretty much my use of git

git add .

git commit -m "-"

git push

Real men don't need git, just remember your code!

since I have multiple computers, and I want the folders to be synchronized without using cloud services, I use git to update my folders on a USB key working as remote repo :-D

it is actually pretty convenient

Bastian Treichler

same here, but I use dropbox to sync them.. my git working copies are in the dropbox folder

that way I can work on some code, continue the work on the other computer, and commit when the work is done

there's a small risk that dropbox corrupts the working copy.. but that's no problem if you git-push the stuff to github or whatever

skill patrol

@yuggib Why don't you want to use cloud services?

yuggib

Because I prefer to have some feeling of control over my files and sensible data

skill patrol

makes sense

yuggib

I want a small delusion of privacy...

I even keep my passwords in an encrypted file...the day I forget my passkey I am screwed :-D

4:25 PM

Bastian Treichler

why can't I use two \tag expressions in one MathJax $$ statement?

without using \begin{align}

\tag{1}a=b \\ \tag{2} c=d seems to be illegal

ACuriousMind

@BastianTreichler You shouldn't use `\` in `$$...$$` to begin with

Bastian Treichler

ok why?

worked great so far

ACuriousMind

Dammit, MathJax doesn't play nice

@BastianTreichler Well...the lines are not aligned. You don't have any control over how the next line is placed in relation to the previous one

And everything between two double dollars counts as one single equation for all purposes.

Bastian Treichler

well if you want control you can use \begin{align}, but then again you're starting your $$ with a ``

with a \\

ACuriousMind

4:39 PM

Additionally, if you're typing this in proper LaTeX , you should use double dollars but \begin{equation}

(and \end{equation})

Bastian Treichler

(only one backslash, don't know how to escape it)

ok

ACuriousMind

Re the double dollars, see:

280

Q: Why is \[ ... \] preferable to $$ ... $$?

I've heard that you should use \[ ... \] for displayed equations instead of $$ ... $$, but why is that? I'd assumed that it's so that you can more easily tell which are starting and which are ending delimiters, but if I always use a syntax-highlighting text editor, I can see that easily based o...

Yeah...great job, ChatJax

@BastianTreichler I don't know what you mean, exactly

yuggib

damn subnets...you could mess up cardinalities very fast

but that's their advantage

probably @_@

Bastian Treichler

thx for the link.. but in MathJax on PSE I have to use the double-dollar, right? and I don't get why one double-dollar block does not accept more than one \tag

ACuriousMind

@BastianTreichler Yes. And it doesn't accept more than one tag because it is, semantically, one equation

And it doesn't make sense to tag one equation with more than one number

That you can use \\ to force a newline in it is because \\ always does that, but the environment is not designed to have more than one line in it.

Bastian Treichler

4:53 PM

oh you meant I shouldn't use the double backslash in a double-dollar statement?

ACuriousMind

Exactly!

Bastian Treichler

I saw only one backslash, sorry, should have understood it

ACuriousMind

Oh...I only typed one, sorry for the confusion

Bastian Treichler

funny thing is, if you use a \begin{align} inside of the double-dollar, it accepts one \tag per line

ACuriousMind

Well, you don't need the double dollar at all when you use begin align (not even on PSE)

Bastian Treichler

4:55 PM

oh thanks didn't know that!

There's a lot of CTC papers in string theory

I am intrigued

0celo7

srs

Slereah

although

I'm not sure if it's about string theory in a CTC background

Or string theory generating CTCs

I will have to sort everything once I saved ALL ARXIV

Only 200 articles or so left to save :p

0celo7

how big is math/physics arxiv

Slereah

Pretty big

But there's only about 300 articles on CTCs

0celo7

written by like 5 guys no doubt

Slereah

5:16 PM

A lot of names show up often yeah

although there's also one time authors

A lot of them are by like

Visser, Hawking, Yurtsever, Morris, Bonnor, Gonzalez-Diaz, Li

Gott also

0celo7

@ACuriousMind I'm confused

when you say "Grüß Gott"

isn't that saying like "greet god"

like "I'm going to shank you and you're gonna greet god"

like you only greet god when you die

Slereah

" Timelike Killing spinors in seven dimensions "

ACuriousMind

@0celo7 It's a shortened form of Grüß dich Gott, where Grüß is the imperative mood.

Slereah

This title feels a lot like "I need to write a paper, the topic isn't important"

0celo7

@ACuriousMind ic

@ACuriousMind AH

that's why my old Bavarian great godfather says Grüßdi

Slereah

5:25 PM

BEI GOTT

0celo7

Deus vult.

@ACuriousMind I figured it was some strange Bavarian word ;)

ACuriousMind

Well, Grüß Gott or Grüß di(ch) are indeed typically Bavarian, so you weren't far off.

You might hear it used by others, but the more North you go, the rarer it becomes

0celo7

@ACuriousMind What's the Alabama of Germany?

ACuriousMind

I have no idea what characterizes the Alabama of America, so I can't answer that :P

0celo7

Mississippi?

Have you ever been here?

ACuriousMind

5:29 PM

No

0celo7

Do you plan to?

And my parents send me pictures of the steak they're having

While I eat grub

ACuriousMind

@0celo7 Not really, but my travels - if any - are always short-time decisions

@0celo7 lol, that's cruel

I found out I'm actually better at cooking steak than my mother.

0celo7

Are you good or is she terrible ;)

ACuriousMind

(After a few attempts, naturally)

@0celo7 She's not terrible, but, well, not really good either

0celo7

Honestly though the food here is good.

I get a salad with beans, chickpeas, mushrooms, peppers, carrots, olives and more every day

Sometimes they have spinach leaves

ACuriousMind

5:33 PM

My main reason not to cook is not that I'm bad at it, but that I'm too lazy :/

0celo7

@ACuriousMind Same

I'd rather curl up in a ball and think about geodesic balls

that's where I am in life...

ACuriousMind

@0celo7 I thought you can't cook in the dorm?

0celo7

@ACuriousMind Yes, but I did live in a house at one point of my life

So long ago...

With a cat

ACuriousMind

Ah, I can't cook when I'm at my parents. My mother is...territorial with the kitchen :D

0celo7

Aww

I don't miss my home

I miss lil Einsteiner

and the dog, to a lesser extent

ACuriousMind

5:36 PM

It's still funny the dog doesn't have a name

0celo7

he does have a name

but we just call him dog unless he's in trouble

his name is Kobi

short for Kobold

Slereah

>not calling him a widdle fuzzy wuzzy

0celo7

I do call him kitty a lot

it comes out as keeeeeeeetty though

or leeettle baby

:(

Slereah

Did you know

The word cobalt comes from Kobold

It's one of the three elements named after monsters

ACuriousMind

I did not know that. Interesting!

I'll bite: Which ones are the other two?

Slereah

5:44 PM

Nickel is one :

"However, when miners were unable to extract any copper from it, they blamed a mischievous sprite of German mythology, Nickel (similar to Old Nick), for besetting the copper. They called this ore Kupfernickel from the German Kupfer for copper."

Hm, which one is the third one

0celo7

@ACuriousMind Einsteinium

ACuriousMind

@Slereah I've never heard of a Nickel. Guess my parents didn't read enough bloody myths to me as a child

0celo7

mine read me 0

you ppl had such nice childhoods

Slereah

I guess you did not grow up in a medieval mining community

0celo7

I had Sido and GTA and happy tree friends
