Oh TCS is Elsevier! I thought it's Springer

I think the way to go is that the academic institutions have to take the responsibility. I know couple journals which are university-driven, and some large publisher (e.g. Cambridge UP) only takes care of printing and proper indexing

Sean Allred

01:29

@PauloCereda I actually saw an article not too long ago that recorded someone doing just that. I'll see if I can find it…

Sean Allred

05:30

@PauloCereda :( youtube.com/watch?v=-F5qgEBHAVM

(Never did find that article, by the way…)

Marco Daniel

@PauloCereda "page not found" :-(

FrameMaker 12 is out, and has support for Mathematics. So I decided to download a trial version and compare it with Latex to see. Well, it does not look good. The PDF output is not bad, but the HTML output is not good. The limits on an integral sign are corrupted in this example. So, I do not think Latex has to worry about this.

This version supports XML they say, but I do not know how to use that part. I was only testing the math support to compare it with Latex.

They use GIF images for equations.

<DIV>
<IMAGE xml:link="simple" href="2-1.gif" show="embed" actuate="auto"/>
</DIV>
That is why the math looks not sharp and fussy

Back to Latex ......

Paulo Cereda

09:35

@MarcoDaniel I decided not to traumatize people. :) It's my code playground for arara. :)

Paulo Cereda

09:51

@egreg: ooh you are close to 30k votes!

egreg

@PauloCereda Still one month.

Paulo Cereda

@egreg You passed percusse, it's already an amazing milestone. :)

Hey I miss @David, where is he these days?

egreg

10:17

@PauloCereda Keeping water from entering his house? :(

Paulo Cereda

@egreg Oh my, the floods. :(

I once saw a flood when in São Paulo, it was one of the scariest things I ever saw. :(

Paulo Cereda

10:31

@DavidCarlisle: Hi David! How are things?

Liar Liar Pants on Fire

watchiung iron man 2!!

Paulo Cereda

10:51

@LiarLiarPantsonFire Iron Man Double Factorial of 2? :)

egreg

@PauloCereda Unimportant: 2!!=2!=2 ;-)

Paulo Cereda

@egreg Oh. :)

egreg

@PauloCereda On the other hand, 4!!≠4! and 3!!≠3!

Paulo Cereda

11:07

@egreg It could be Iron Man 3, than the joke would be funny. :)

Oh boy, I hate those profile pictures you have to have in some articles which require biography. :(

IEEE, I'm looking at you.

Liar Liar Pants on Fire

@PauloCereda no the movie, iron man 2

but now its ended! :D

Paulo Cereda

@LiarLiarPantsonFire Ah Tony ~~Stork~~ Stark. :)

Liar Liar Pants on Fire

@PauloCereda yeah! it was boring, actually i saw it late

Liar Liar Pants on Fire

Bye! Going to Study now!

cgnieder

13:26

Plan for today: work on yesterday's todo list chat.stackexchange.com/transcript/message/13789897#13789897

@egreg We have that, too: Ein Loch ist im Eimer (or Wenn der Pott aber nu en Loch hat) ingeb.org/Lieder/wennderp.html :)

Paulo Cereda

@cgnieder das bucket!

:)

►

cgnieder

@PauloCereda :)

Paulo Cereda

@cgnieder Ein Wasserbucket!

ooh I'm getting better!

@egreg: mom is making tortellini for today! :)

egreg

@PauloCereda Good! I had spaghetti alla carbonara

Paulo Cereda

@egreg Yummy! :)

@egreg: is Naples far from you? When I visit you, I want to try some of their pizzas. :)

cgnieder

13:40

@PauloCereda This could be mistaken for “Wasserbukett” ;) (not that the latter makes much sense, though)

Paulo Cereda

@cgnieder ooh! :P

egreg

@PauloCereda And “crostata” with apples and home made orange marmalade

Paulo Cereda

@egreg yummy! Sometimes mom makes this crostata with guava. :)

egreg

@PauloCereda Just 700 km

Paulo Cereda

@egreg Oh my!

egreg

13:44

@PauloCereda Five hours by train

Paulo Cereda

@egreg A 5-hour TeX course. :)

TeX on Rails!

@egreg: how long does the Macbook battery work?

egreg

@PauloCereda Our fast trains have power sockets

Paulo Cereda

@egreg Really?!

That's new for me.

Well, Brazilian stuff cannot be compared to other countries. :)

egreg

@PauloCereda From my programming book

Paulo Cereda

@egreg LOL pure gold!

egreg

13:54

@PauloCereda Now TV for the match. Bye.

Paulo Cereda

@egreg See ya. :) We will be back in the half time for highlights. :)

Christoph

14:15

I need some pointers here. Situation: I have a terrible hangover and my girlfriend asked me to typeset a short text for her students, mainly law text.

Paulo Cereda

@egreg: Goal!

cgnieder

@Christoph ASS, orange juice and coffee?

Christoph

no juice, already tried the rest. I even begin feeling better but that might be measurement noise

Paulo Cereda

@Christoph Coffee. Lots of it. Without sugar.

Christoph

I never dilute my coffee with sugar!

cgnieder

14:22

Christoph

WTF!?

Paulo Cereda

@cgnieder Germans? :)

Christoph

yes

cgnieder

@Christoph I have never typed any law texts but isn't there a dedicated KOMA-SCript class?

Christoph

I'll check...

cgnieder

14:25

@PauloCereda that's what social media and internet are for: to collect funny/strange/stupid/... pictures ;)

Christoph

add "disturbing" to your list to make the picture a valid entry

Paulo Cereda

@cgnieder And ducks! :)

cgnieder

@PauloCereda Of course ducks! Probably the most important point :)

Paulo Cereda

@cgnieder :)

Christoph

my koma documentation only shows the main classes scrbook, scrreport, scrartcl, scrlttr2 and scrpage2. Nothing really law-related

I might just go with scrartcl cram in a page header and use the multicol package for the main text

Paulo Cereda

14:30

@egreg: Goal!

Henri Menke

Hello friends!

cgnieder

@Christoph found it - the package is called scrjura and has it's own manual: mirrors.ctan.org/macros/latex/contrib/koma-script/doc/…

Henri Menke

I wanted to ask, if there is a best practice for posting answers with extremely long cope snippets. I just posted this answer and used GitHub Gist to store the file.

Christoph

@cgnieder thanks, looking into it

is there a way to complete @userna... with a keyboard shortcut?

Torbjørn T.

@Christoph For the names that pop up when you start typing the, the tab-key.

Paulo Cereda

14:45

@egreg: nice first half! :)

Christoph

thanks @TorbjørnT.

Paulo Cereda

@HenriMenke oh hello!

@HenriMenke I think it's fine. :)

Henri Menke

@PauloCereda Okay, thank you! Then I'll stick with that.

egreg

@PauloCereda Too lazy in the end.

Paulo Cereda

@egreg Ah yes. By the way, I didn't know Giovinco was back.

Henri Menke

14:52

@PauloCereda BTW: arara is awesome. If we ever meet I owe you a beer!

Paulo Cereda

@HenriMenke aww thank you for the kind words. :)

Wait for the new version, we are working on something really awesome. :)

It's like learning from our own mistakes, meaning that we are ready for way bigger mistakes. :)

3

Henri Menke

@PauloCereda Even more awesome?! You're making your way to a whole crate of beer ;)

Paulo Cereda

@HenriMenke We are beer-powered. :) Don't forget that our team has a German majority. :)

Marco, Clemens and Heiko. :)

cgnieder

@PauloCereda Although I have no idea what I'm actually doing for the team? :) Nothing so far I think

Paulo Cereda

@cgnieder Expect some internal team communication. :) They are very secret. Even I don't know what I write about. :)

cgnieder

15:01

@PauloCereda ooh! TeX conspiracies... ;)

Paulo Cereda

@cgnieder shhh. :)

All our secret reunions should happen in a Bierhaus.

@egreg: Goal!

rm -rf

I'm sure there must be a question on this, but I can't seem to find it... My font (Fontin) doesn't have the character ğ — is there some way I can create it?

cgnieder

15:21

@PauloCereda Hmm, beer! :)

Paulo Cereda

@cgnieder That's how we work: we discuss things before beers, then the very same things after beers; the ones that keep coherent after this step, we move on. :)

cgnieder

@PauloCereda sounds like a reasonable plan :)

Paulo Cereda

@cgnieder Of course, we need a designated driver.

cgnieder

@PauloCereda I don't have a car :p

Paulo Cereda

@cgnieder Let's go with Marco!

woohoo

cgnieder

15:31

@PauloCereda I'm sure he won't mind ;)

John

@egreg: is this in Brill? i.sstatic.net/esIbt.png

If so when I was trying to make something similar I could only find an outlined index, not a black one

never mind

egreg

16:00

@John Utopia

@rm-rf \usepackage{newunicodechar}\newunicodechar{ğ}{\u{g}} But it's not guaranteed.

Paulo Cereda

@egreg: good game. :)

rm -rf

@egreg Nope, no luck :(

egreg

@PauloCereda A bit of laziness, but next Thursday there's the Europe League match.

Paulo Cereda

@egreg Ah yes, the big game. :)

egreg

@rm-rf Let me check

@rm-rf Unfortunately Fontin doesn't have a combining breve; here's how you can do it:

\documentclass{article}
\usepackage{fontspec,newunicodechar}
\UndeclareUTFcomposite[\UTFencname]{x011F}{\u}{g}
\newunicodechar{ğ}{\accent"02D8 g}

\setmainfont{Fontin}

\begin{document}
ğ
\end{document}

rm -rf

16:13

@egreg Excellent! Thank you :)

Paulo Cereda

17:44

@egreg: can I ask a newbie math question? :(

tohecz

18:45

@PauloCereda hit us :)

Paulo Cereda

@tohecz Don't laugh, please. :)

tohecz

@PauloCereda I've been asked many ridiculous things, don't worry man

Paulo Cereda

@tohecz :)

Suppose I have a set A = { a, b, c }. I'd like to have a new set B with all the possible subsets of A, with size 2, B = { { a, b } , { b, c } , { a, c } }, but I don't know a good "generic" notation for that. :(

At least, I can't think of one.

tohecz

We use {A \choose 2}

It's quite standard, still you should properly define it of course

Paulo Cereda

@tohecz Oh.

Paulo Cereda

19:18

@tohecz I'll take a look here. :) Thanks, Tom. :)

tohecz

@PauloCereda Was the SE off for you, too?

Paulo Cereda

@tohecz Yes, it was. :(

tohecz

@PauloCereda well, needed to say, glad to hear that :-/

sound.SE still off it seems

some problem on SE site probably

@Paulo btw, do you know that feeling that your favourite musical e-shop has all sorts of audio cables, but not the one you need?

Paulo Cereda

@tohecz Uh-oh. :(

tohecz

@PauloCereda I actually can't find that one anywhere

Paulo Cereda

19:35

@tohecz Ouch, that sucks. :(

tohecz

@PauloCereda well, I can use a reduction, but then I lose quality, or I can ask for a one-piece made cable, but then I lose quality too (and it's expensive)

Paulo Cereda

Hi @David!

@tohecz: this is bad, isn't it?

A = \{ a, b, c \}, B = \{ \{ a, b \} \mid a, b \in A, a \neq b \}

tohecz

this is bad. What about:
\[ A = \{a,b,c\}, B = \{S\subseteq A \mid \# S=2 \} \]

or: $B = \binom{A}{2}$, i.e., $B$ is the set of all subsets of $A$ of size $2$.

The notation is standard (especially in graph theory, and combinatorics), so don't re-invent the wheel :)

Paulo Cereda

19:55

@tohecz Oh my, I'm ashamed. :(

@tohecz Thank you very much, Tom. :)

tohecz

@PauloCereda haha, don't be

I tell you, it is soooooo difficult to write things clearly, and I'm far from being able to do so

Paulo Cereda

@tohecz I know some maths, but sadly the trend in Brazil is to "loose" the formal stuff in favour of practical stuff. When submitting things abroad, we need to go formal, and that's where I see I'm very rusty. :)

tohecz

@PauloCereda It's difficult to be precise yet readable

Paulo Cereda

@tohecz Yes. :)

tohecz

btw, found the cable, but from a brand I don't know :-/

Paulo Cereda

20:05

@tohecz Monster cable? :)

egreg

Back on line, at least the chat. The main site is still down

But stackoverflow.com is up

tohecz

@PauloCereda unfortunately not :( I found two: PROEL and CORDIAL

And another problem is that the vendors are far from me so + €4 just for PnP

egreg

@PauloCereda Also \mathcal{P}_{2}(A), which can be also \mathcal{P}_{\le2}(A) for the subsets of at most two elements; or \mathcal{P}_{<\omega}(A) for the finite subsets.

Paulo Cereda

@egreg Thank you!

@tohecz: ^^ the master in action. :)

Q: What just happened to StackOverflow?

StackOverflow was down for a long time here, probably about an hour. Anybody know what the cause was?

tohecz

20:11

@egreg I've never seen it, but that's probably because I'm not doing algebra ;)

egreg

A: What just happened to StackOverflow?

The StackStatus twitter account says this: Our network provider is experiencing a bit of increased traffic. We and they are investigating. Update: We have partially mitigated a DDoS attack against our network. We are continuing to watch traffic.

@tohecz \binom{A}{2} is good as well.

tohecz

@egreg as I say, it's quite standard, and I like the "comutativity" of $\#\binom{A}{2} = \binom{\#A}{2}$ :)

egreg

For a finite set $A$ of size $n$ we have $2^A=\bigcup_{0\le k\le n}\binom{A}{k}$

tohecz

btw, going through the list of chat rooms, and some are really funny: The Appendix (do you still have your appendix?), The Water Cooler (no, thanks, it's too cold outside anyways), The Observatory, and most importantly, remember that You Are Here :)

@egreg Could I consult a LaTeXnical detail with you please?

egreg

20:30

@tohecz Of course

tohecz

Imagine I have a command like \NomenclatureItem{<symbol>}{<description>}. Now, symbol is always a math guy, so it would be reasonable to define it like \NomenclatureItem -> $ #1 $ --- #2 (formatting doesn't matter now).

But it has a drawback, which is when someone writes \NomenclatureItem{$S$}{My set} instead of \NomenclatureItem{S}{My set}. Any ideas? What variant would you prefer?

egreg

@tohecz The latter, with the explicit math.

tohecz

@egreg Sorry, so you'd prefer writing \NomItem{$S$}{My set} ?

Paulo Cereda

@egreg: how do you like the idea of a natural language-based arara directive?

egreg

@tohecz Yes, it's a math symbol, so let be it.

@PauloCereda “Please, LaTeX it for me”?

jtbandes

20:34

I was using \beamertemplatenavigationsymbolsempty to get rid of Beamer's navigation bar... but it doesn't seem to work anymore. Perhaps changed with a recent package update. Does anyone know any alternatives?

tohecz

@egreg ok. Thanks

Paulo Cereda

@egreg Close. :)

% arara: frontespizio with engine(xelatex)

egreg

@PauloCereda Nice!

tohecz

@PauloCereda "Prosím, pusť LaTeX na můj soubor!" ?

Paulo Cereda

@tohecz OMG

@egreg Courtesy of Brent. :)

egreg

20:36

@tohecz Of course, we want users to be polite.

tohecz

@PauloCereda literally, "Please, drop LaTeX onto my file" :)

Paulo Cereda

% arara: pdflatex with shell(yes) and synctex(yes)

@tohecz UTF8 required. :)

tohecz

@PauloCereda cp1250cs suffices ;) :p

Paulo Cereda

@tohecz :)

tohecz

@jtbandes I was just going to mention that there's a question about it on the site, to realize that the site is still off

Paulo Cereda

20:39

@egreg, @tohecz: I could add some politeness level that might make users to eventually include a "please" keyword somewhere. :)

tohecz

@PauloCereda Like this?

arara> This is a toughie, manna! You oughtta say "please" or there ain't no work

jtbandes

@tohecz Hm ok. Do you know if anyone answered yet? :)

tohecz

@jtbandes there's a solution that doesn't use the command, but I don't know it

oh sorry, I don't mean the fact that the command doesn't work, I mean that there's a question about hiding the navigation bar

jtbandes

ah, I see

I just looked at the command definition in beamerbasecompatibility.sty, it does \setbeamertemplate{navigation symbols}{}

Naturally, this doesn't work anymore either

tohecz

@jtbandes If you try \setbeamertemplate{navigation symbols}{ABC} ?

jtbandes

20:45

Wait — I just realized I'm being stupid.

\beamertemplatenavigationsymbolsempty still works — but there's a new bar which didn't exist before

tohecz

@jtbandes Well, you're probably not ;)

Speravir

Hello @ all. StackExchange is back, but TeX.SX is still dead here. How is it for you? Last reachable server in traceroute here “nyk-b6-link.telia.net [80.91.253.93]”.

jtbandes

@Speravir Looks like *.stackexchange.com is still broken, but stackoverflow.com works

egreg

@Speravir DDoS attack

tohecz

@Speravir welcome to the club pal

Speravir

20:46

Oops. Thanks guys.

@PauloCereda While searching I found this one, did you already know? Olá, Mundo! Announcing Stack Overflow in Portuguese.

Paulo Cereda

@Speravir I knew about it, and, personally, I found it very insulting. :) Not sure if I should expand a lot about this subject... :)

Speravir

@PauloCereda OK. Should I delete my posting? ;-)

Paulo Cereda

@Speravir Nah, don't worry. :) I meant the SO in Portuguese, not your message. :)

Speravir

@PauloCereda Another topic: Your nightingale logo is again awesome IMHO!

Paulo Cereda

The reason for my rage is that a lot of Brazilians that work with software development or even in academia, IMHO, is very lazy and fail to make an effort on trying to learn new things when these things are not in Portuguese. Making a SO in Portuguese doesn't cover a demographic need of the language expansion, but makes people more lazy to move their buttocks out of their comfy chairs and try to interact with the rest of the world. :)

@Speravir Oh thanks! I plan to revamp the arara logo as well, in the same lines. :)

@topskip: Yay, Patrick is back from the <xml>conference</xml>! <3

topskip

20:54

@PauloCereda Nice conference. A former TeX guru is always there (Norm Walsh)

And someone presented a nicely working MS-Word to LaTeX converter

Paulo Cereda

@topskip Wait for the TeX conference I'll host someday. :)

There'll be lots of gaming stuff in the lounge, ducks, puppies and some comfy chairs. :)

topskip

@PauloCereda I wanted to say that it beats the TeX conferences I have been to in the past

Paulo Cereda

@topskip Oh. :)

egreg

@GonzaloMedina Well, it was to the whole SE network, apparently.

Johannes_B

20:59

@PauloCereda I can't wait

Paulo Cereda

@Johannes_B Think of @egreg and @DavidCarlisle playing Mario Kart in the lounge. :)

Gonzalo Medina

@egreg stackexchange.com is up, so perhaps it was only to some of the sites?

Paulo Cereda

Of course, @Gonzalo can't play because he's a pro at gaming. :P

egreg

@GonzaloMedina It was down until a few minutes ago.

Johannes_B

@PauloCereda Sounds awesome.

egreg

21:01

@PauloCereda We could play "macro expansion"

5

Paulo Cereda

@egreg OMG TeX games!

We could play Scrabble with macros instead of words.

egreg

@PauloCereda Are macros with @ allowed?

Paulo Cereda

I don't know how to spell that game. :(

topskip

@PauloCereda Actually Pont a Mousson in 2005 was great, Knuth and Zapf were there

Paulo Cereda

@egreg Yes! :)

@topskip oh my!

egreg

21:03

@PauloCereda Do you think that some people won't behave? So they'll deserve to be punished with the comfy chair?

Paulo Cereda

@egreg It's very possible. :) I need to find the comfiest chair available. :)

Is comfiest a valid word?

Gonzalo Medina

@PauloCereda Why not? You just wrote it :-)

Paulo Cereda

@GonzaloMedina ooh! :)

tohecz

my brother is teaching English, and he says: A word is valid if people understand it. Especially if you're not a professional speaker

egreg

@PauloCereda In English anything is allowed, except nouning verbs.

Paulo Cereda

21:06

@egreg ooh! :)

> I hate when people get random macros from random question and human-centipede them together in one random document.

Warning: don't even google that, it's a bad movie. :)

egreg

@PauloCereda On Math.SE one often finds "proof that …”, instead of "prove that …"

Paulo Cereda

@egreg ooh! :)

@egreg: I was curious about the tombstone name in typography for the \qed symbol and found that halmos is another name for it. :)

egreg

@PauloCereda We should ask barbara

What I know is that Halmos was the first to use it for denoting "end of proof"

Paulo Cereda

@egreg oh cool!

Tombstone (typography)

The tombstone, Halmos, or end of proof mark "" is used in mathematics to denote the end of a proof, in place of the traditional abbreviation "QED" for the Latin phrase "quod erat demonstrandum" (Q.E.D.). In magazines, it is one of the various symbols used to indicate the end of an article. In Unicode, it is represented as character . Its graphic form varies. It may be a hollow or filled rectangle or square. In AMS-LaTeX, the symbol is automatically appended at the end of a proof environment \begin{proof} ... \end{proof}. It can also be obtained from the commands \qedsymbol or \qed (the ...

@egreg I found it in here. :)

Speravir

Seems twitter.com/StackStatus was ddosed, too: no mention about subdomains. (add missing smilies here.)

egreg

21:13

@PauloCereda Probably "tombstone" because the one used by Halmos was rectangular, higher than wide, and black.

Paulo Cereda

@egreg :)

Johannes_B

@PauloCereda Where is this quote from?

egreg

@PauloCereda A bit fatter than the last one in the picture.

Paulo Cereda

@Johannes_B I wrote it now. :P

We were talking about making up new words in English. :P

Johannes_B

@PauloCereda Nice one. ;-)

Paulo Cereda

21:15

@Johannes_B Thanks. :P

Gonzalo Medina

@PauloCereda can you please remind me how to ask something to PSmith?

Paulo Cereda

@GonzaloMedina !!/answer <question> if we need to rely on Wolfram|Alpha, or !!/eightball <question> for yes/no questions. :)

@Speravir The answer is known: the DNS records for SE have to change all over the internet. The site is on, just with a different IP :-/

Speravir

@tohecz Yes, I got a comment.

Speravir

@egreg Not here. But see answers to my linked Meta.SO question.

@egreg OOOH. I should have flushed DNS cache again.

tohecz

@egreg Back for life, and I've just recieved an article review: "In my opinion this paper will be reconsidered when the authors check the proofs and rewrite carefully the text." That's a Pyrrhic victory :-/

Speravir

I wonder who would launch a DDOS on SE? Somebody who got banned and wanted revenge? :P — Mysticial 2 hours ago

@Mystical: Whoever did it, I'm sure at one point in their development of the DDOS tool they got advice from SE. (Assuming the people who launched it developed the tool, which is probably unlikely...) — Chris Laplante 2 hours ago

Lousy losers (for another meanwhile deleted article with same content see answer in my question):
