@PauloCereda what kind of bus is this?

@JosephWright He is Dutch. It doesn't compute that way :)

7:17 AM

Can someone help my quick? (Don't think it warrants a question on the main board). I'm using longtable and getting 'multiply defined labels'.

\noindent\begin{longtable}{>{\raggedright\arraybackslash}p{.17\textwidth}*{5}{S}}
\caption {Descriptive Statistics (\%): Whole Sample ($N = \num{13 298}$)} \\
\label{table:DSWSS}\\

Joseph Wright

@Chris You need to put the label just in the 'first head'

Chris

8:19 AM

Ah ok, but where would that be in the following code (sorry for the 'newbie question', but this is literally the first time I'm using a longtable, and the code below was produced by someone else for me):

\noindent\begin{longtable}{>{\raggedright\arraybackslash}p{.17\textwidth}*{5}{S}}% don't use vertical rules with booktabs (see the documentation)
\caption {Descriptive Statistics (\%): Commerce Faculty ($N = \num{7028}$)}
\toprule
% define \endfirsthead if first head differs from later heads
{\bfseries\hskip0pt Variable} & \multicolumn{1}{p{.17\textwidth}}{\bfseries\hskip0pt Proportion of …

oh oops, my \label{table:DSWSS} \\ should be just after the \caption{..} line

Q: At what speed should I stop "punting"

In Extreme Tux Racer game, from certain speed, it doesn't make sense to "punt" anymore by pressing the top arrow since it starts to slow you down. I know it's somewhere below 65 km/h, but I don't know at what speed it happens exactly. So the question is: when to stop "punting"? (I'm afraid that ...

@PauloCereda Survived your trip?

Paulo Cereda

@JosephWright Hi! :) Apparently yes. :) It was not as bad as I thought it would be. :)

What did I miss? :)

@JosephWright: Spam! tex.stackexchange.com/questions/183657/seeking-out-for-bred-11s

David Carlisle

10:11 AM

@Chris don't do \noindent\begin{longtable :-) It just makes a spurious white line that won't be discarded at a page break

@Chris % define \endfirsthead if first head differs from later heads that's a bit misleadiing, if you have a caption in the head you want to use \endfirsthead as as well as multiple labels it will write to the list of tables every time

Paulo Cereda

10:30 AM

@David: so England is already out of the World Cup?

David Carlisle

@PauloCereda Anyway I don't care about England in that competition, I drew Chile and Uruguay in the Office sweepstake....

Paulo Cereda

@DavidCarlisle I can understand about Uruguay, but Chile?!

You could ask me about South American football. :)

David Carlisle

@PauloCereda for a sweepstake understanding isn't required: you pay a pound and draw a name out of a jar one who gets the name that wins takes the pot of money at the end, it's a zero sum, zero skill form of betting:-)

Paulo Cereda

@DavidCarlisle ooh I like the sound of it. :)

We could organize a TeX.sx bet.

Just for fun. :)

David Carlisle

@PauloCereda ok you ask "who will win the world cup" and anyone who answers has to pick a name not already given, and promise a 50 bounty on the winning answer

Paulo Cereda

10:45 AM

@DavidCarlisle ooh!

They will ban us from SX if we do that, won't they? :)

@JosephWright: we need advice. ^^ :)

egreg

@PauloCereda Uruguay is a very dangerous client when the World Cup is in Brazil.

Paulo Cereda

@egreg Indeed. :) Poor Barbosa (the goalkeeper in that day).

@egreg: one year later, Palmeiras won the Taça Rio. :P

Paulo Cereda

@egreg: In Brazil, the most you get for any crime is 30 years. For 50 years I’ve been paying for a crime I did not commit. Even a criminal when he has paid his debt is forgiven. But I have never been forgiven. I remember watching him saying this on TV in an interview. It was very sad.

egreg

11:01 AM

@PauloCereda Really. It's never a single player's fault. Who allowed Ghiggia shooting from a good place?

Paulo Cereda

@egreg Exactly.

@egreg: there's another story that I read about a game in the Maracanã. Does Julinho Botelho ring a bell? :)

egreg

@PauloCereda He played in Italy before I was born (notwithstanding what @DavidCarlisle might say).

Paulo Cereda

@egreg Yep, he was from Palmeiras and went to Fiorentina. :)

egreg

@PauloCereda Ghiggia also played for Italy.

Paulo Cereda

@egreg Really? I didn't know that.

David Carlisle

11:07 AM

@egreg do they play football in Italy?

egreg

@PauloCereda He played eight years for Roma and one for Milan.

@DavidCarlisle Sometimes.

Paulo Cereda

@egreg: It was in 1959, a friendly match against England. The coach didn't pick Garrincha for the game lineup (some say Garrincha was drunk), so Julinho took his place in the formation. But when the stadium speaker announced that Julinho was gonna play instead of Garrincha, the crowd started the biggest boo in the story of mankind (being the majority from Rio and also from a press pressure, they wanted to see Garrincha). >>>

egreg

@PauloCereda Everybody would have liked seeing Garrincha play. ;-) But do you remember Ronaldo in a famous match?

Paulo Cereda

Historians say it were 5 minutes of 125k+ people booing a person for just being picked to play, and Djalma Santos told later that Julinho cried during the whole time. He scored a goal in the game and was applauded. When he was way older, Julinho told in an interview that he was still able to hear the boos echoing inside his head. :(

@egreg Which one? :)

egreg

@PauloCereda The one when he was sick: “Brazil lost the final to hosts France 3–0”.

Paulo Cereda

11:14 AM

@egreg ooh I want to forget that game. :) Zidane was truly inspired that day.

egreg

@PauloCereda I thought you had forgotten it. ;-)

A: bibtex vs. biber and biblatex vs. natbib

(The following is an expansion of the biblatex tag entry, which I helped to write). First, some distinctions: bibtex and biber are external programs that process bibliography information and act (roughly) as the interface between your .bib file and your LaTeX document. natbib and biblatex are La...

I am not soo happy with the last edit. 3 out of 4 are valid for bibtex and biblatex/biber

Joseph Wright

12:34 PM

@Johannes_B You are free to edit: I'd certainly agree that tools for managing .bib files are equally applicable to all cases

egreg

12:47 PM

@Johannes_B The point about easy inclusion of the .bbl file is good: at the moment, biblatex can't offer anything similar. The large amount of .bst files is both a strength and a weakness: among those .bst files there's much rubbish.

Hi
I want to know the program (i.e. software) that is useful for plotting figures in latex. currently I use MS word, and save the picture as JPG, then I go to a website to change it to eps format.
I think this is not efficient way for plotting figures. So, I want to know what is the best way to plot figures in Latex.
Thanks

Joseph Wright

@barznjy Several options: pgfplots, PSTricks, Asymptote, ...

barznjy

@JosephWright are they free softwares? could you send me the download link?

Joseph Wright

@barznjy pgfplots and PSTricks are (La)TeX packages, Asymptote is a separate program: asymptote.sourceforge.net

barznjy

@JosephWright Thanks. I am downloading Asymptote.

@JosephWright This is a programming language, do you know any software that is easier than Asymptote?

Joseph Wright

1:00 PM

@barznjy LaTeX 'drawing' always comes down to programming

@barznjy Personally, I use pgfplots for my plot production, but you still need to write 'scripts'

@barznjy Perhaps more graphical are GNUplot or GLE, os something like QtiPlot

QtiPlot is an open-source clone of sorts of Origin

barznjy

@JosephWright Thank you.

Paulo Cereda

1:20 PM

@HeikoOberdiek: my compiler is finished. :)

egreg

@PauloCereda Metametametacompiler? For which a metametametametacompiler is needed?

I need to go for the preliminary operations of the polling station. Tomorrow is a rep harvesting day for you all.

Paulo Cereda

@egreg To generate a metametametacompiler. :)

Heiko Oberdiek

1:50 PM

@PauloCereda Just in time. Now you have time for the real important things: FIFA World Cup in Brazil. :-)

1010011010

2:45 PM

Any package better suited for implementing algorithms than pgfmath? pgfmath does things like the signum function just fine: \pgfmathparse{#1 > 0 ? 1 : -1}, but I'm looking for something more flexible. :-)

Joseph Wright

@1010011010 That's not a function, that's C :-)

@1010011010 More seriously, what are you trying to achieve? TeX is not a computer mathematics system: if you want to do that, use a proper tool.

Paulo Cereda

@HeikoOberdiek Ouch, I was nearby the stadium yesterday. It was very chaotic. :)

1010011010

@JosephWright Approximation of the quantile function for arbitrary significance level and degrees of freedom.

@JosephWright Student's t-quantile *

Paulo Cereda

@Heiko: what's your team? :) (not the national, the local... I know Marco is Bayern, Pat and Stephan are Dortmund). :)

1010011010

I intend to mimic the algorithm used in R and... yeah I think it can be done one way or the other.

1010011010

3:12 PM

else if can be used inside \pgfmathparse{}?

Can't get it to work ?

Joseph Wright

@1010011010 Example?

Heiko Oberdiek

3:25 PM

@PauloCereda TeX/LaTeX, of course. Is there anything that is more important?

1010011010

@JosephWright I think what I need is a nested version of ifthenelse: \pgfmathparse{ifthenelse(x<0,ifthenelse(x>-3,x,-x^2),x^2)}

Joseph Wright

@HeikoOberdiek :-)

@HeikoOberdiek Sounds about right

Paulo Cereda

@HeikoOberdiek If I ever organize a TUG conference, it will end up with a football activity. :) Of course, picking up teams will be powered by a TeX code. :)

1010011010

@JosephWright You seem to be savvy of pgfmath. Surely you know what \pgfmath@smuggleone does? I suspect it combines two functions but I'll just be guessing this way.

Oh, and it has the suffix \pgfmathresult. Final declaration to the originally declared function????

Joseph Wright

4:08 PM

@1010011010 No, it's to do with TeX's grouping system

1010011010

@JosephWright So it takes the result "across the pond" outside the group?

Joseph Wright

@1010011010 Yes, hence 'smuggle'

Alan Munn

5:05 PM

Hi @JosephWright (and others welcome to chime in): an edit was recently made the the natbib/biblatex/bibtex/biber question adding in some more advantages to using bibtex. I reverted one part of the edit because it really wasn't about the bibtex vs. biber distinction, but now reading the whole answer again I'm inclined to revert almost all of it for the same reason. (more...)

It's not that big a deal, but I would like opinions on the section that deals with advantages of bibtex. Some of the added advantages are really about natbib not bibtex, which was the whole point of making that distinction clear in the answer. Now it's muddied again. Should I revert back to the previous version?

Joseph Wright

6:14 PM

@AlanMunn Probably needs a proper clean-up to make it clear how 'BibTeX' is being used in different contexts

Alan Munn

6:44 PM

@JosephWright That's what the very first paragraphs of the answer say. But maybe I need to make it bigger or repeat it in the bibtex part of the answer.

Alan Munn

7:09 PM

@JosephWright (and anyone else) I've taken a crack at revising the natbib/biblatex/bibtex/biber question to be much clearer on the terms. Comments welcome.

Joseph Wright

@AlanMunn Looks good

Paulo Cereda

Welcome to the Answ... oh wait.

@PauloCereda Psmith, the TeX bot: The great 8-ball says: cannot predict now.

@JosephWright Oh no!

But David apparently doesn't care, he wants either Chile or Uruguay to get the cup, and he gets the money jar. :)

Let me check where England will play.

egreg

Paulo Cereda

@egreg Psmith, the TeX bot: The great 8-ball says: yes.

@egreg Oh no! :)

egreg

@PauloCereda Psmith must have some insider info.

Paulo Cereda

@egreg: how about we broadcast live the games in here? Then we can get a insider analysis of David. :)

@egreg At least the game is at night. But Italy will play Uruguay in Rio Grande do Norte at 1PM! It's crazy to say the least.

Hi

Until recently I always get the following error using Lualatex+babel with the option ngerman or german: Package babel Info: Making " an active character on input line 88.
luatex-hyphen: loading patterns and exceptions for: ngerman (\language43)
! Conflicting pattern ignored.

\fi \fi
l.140 \ldf@finish\CurrentOption

The same problem as described in mrunix.de/forums/showthread.php?p=358532 , I'd guess, but neither a new installation of MikTeX nor updating the formats manually solved the problem

anyone any idea?

Unil recently is wrong, Since recently is probably more correct
