@AlanMunn LOL

@JasperLoy I usually took 2 days to configure everything in Slackware. :)

6 hours later…

7:45 AM

@Canageek What I'm getting at is that MiKTeX also only includes 'free' software, but as there is only Christian to do the work of identifying material there can be a few he misses. Also, I think he's a bit more forgiving on 'material which is itself free but which requires non-free additions to be useful'.

Is there an easy way to figure out the min of two numbers in latex?

I need to store that result for later

@N3buchadnezzar 'numbers'? Integers, floating points, dimensions, ...?

@JosephWright Oh, decimal numbers.

\documentclass{article}
\usepackage{tkz-euclide,calc}
\begin{document}
\begin{tikzpicture}
\def\a{0.40} \def\b{0.60} \def\c{0.20}
\def\h{\minof{\a}{\b}}
\tkzDefPoint(0,0){A}
\tkzLabelPoint(A){$\h$}
\end{tikzpicture}
\end{document}

This failed.

@N3buchadnezzar: I found this function in the TikZ manual:

\pgfmathparse{min(3,4,-2,250,-8,100)} \pgfmathresult

@N3buchadnezzar I'd probably use the new LaTeX3 fpu here

\documentclass{article}
\usepackage{tkz-euclide,calc,expl3}
\ExplSyntaxOn
\cs_new:Npn \fpmin #1#2 { \fp_eval:n { min (#1, #2)} }
\ExplSyntaxOff
\begin{document}
\begin{tikzpicture}
\def\a{0.40} \def\b{0.60} \def\c{0.20}
\edef\h{\fpmin{\a}{\b}}
\tkzDefPoint(0,0){A}
\tkzLabelPoint(A){$\h$}
\end{tikzpicture}
\end{document}

but I think @PauloCereda's solution is probably easier to set up :-)

For two values, there's also \pgfmathmin{a}{b}. :)

12:01 PM

Indeed ;) I decided to go for squares in my venn diagrams, they are a tad easier to controll the size of ;)

@JosephWright ooh I like the L3 witchcraft. :)

@JosephWright I like your solution aswell =)

@PauloCereda The new FPU will go to CTAN probably later this week

@JosephWright Fantastic. :) I'm really tempted to delve into the bowels of L3. :) Both syntax and code style are very very appealing to me. :)

@N3buchadnezzar If you can't decide between using a billion lines of L3 or a billion lines of pgf you could go with one line of \ifdim#1pt<#2pt #1 else #2\fi

12:05 PM

I want to buy a T-shirt, a mug, and a sticker. Can I have a shirt with "I use LaTeX3. If you see me running try to keep up!"?

@DavidCarlisle True, but the FPU will work for much bigger numbers :-)

@DavidCarlisle :)

Out curiosity, any ternary operation in TeX?

min = (a < b) ? a : b

@PauloCereda You only need the ternery construct in C because the imperative programming style distinguishes the if statement from expressions. In expression based languages like tex you just need if

@DavidCarlisle Ah I see, makes sense. :)

Hmm

\def\a{0.40} \def\b{0.60} \def\c{0.20}
\pgfmathparse{min(\a/2,\b/2)} \pgfmathresult
\def\h{\pgfmathresult} \def\g{\c/\h}

This did not work =/

12:22 PM

@N3buchadnezzar You'll need to \edef the results here

2 hours later…

2:15 PM

@DavidCarlisle Interesting \noexpand puzzle! For some reasons, if e-TeX is used, seven \noexpand tokens are necessary to trigger the error.

@DavidCarlisle And \noexpand in place of \empty doesn't matter: with seven (legacy TeX) or eight (e-TeX) the error is triggered.

@egreg so it requires someone happy to stare at tex.web I think. Where's @FrankMittelbach when you need him:-)

@DavidCarlisle I tried, but I'm definitely no expert.

According to the rules, the unexpandability of a \noexpand marked control sequence should not matter here.

@egreg well i suppose it matters in that the unexpanded token is put back but then seen again as the dimen parser expands everything it sees so you use up input stack, but 8i,4n,0p,80b,22s stack positions out of 5000i,500n,10000p,200000b,50000s

8 out of 5000 shouldn't be that painful:-(

@DavidCarlisle And indeed the error is not about memory. It seems that after a sufficiently high number of \noexpands the following token is permanently marked as equivalent to \relax

2:34 PM

Hi all

@clabacchio Hoy

@N3buchadnezzar 'sup?

\LaTeX

@clabacchio You?

hahha

small question

@N3buchadnezzar thesis ->LaTeX

but it's 5 characters too wide

the line I mean

how can I shrink it a bit?

@tohecz: Sorry for the non-TeX suggestion for your question here: tex.stackexchange.com/questions/62847/…. I wrote a humble app to split the pages: github.com/cereda/a5converter

But I'm still struggling how to generate only one output. It might take a while, I'm crowed with work this week. :(

2:43 PM

@clabacchio You have a url or something, that makes one line spill outside the page margins?

@N3buchadnezzar no, but my university requires 65/70 chars per line

I have like 75

not a big deal

Well I think I have the solution ;)

@N3buchadnezzar I'm listening :)

\usepackage{microtype}

Here is the package documentation ctan.uib.no/macros/latex/contrib/microtype/microtype.pdf

You will need to do some fine tuning, but I am quite sure you can be able to figure that out. I guess an alternative solution is to shrink the margins, or increase the font size. But universities, tend to be strict for those kind of things so.

Perhaps fidde around with \usepackage[letterspace=2]{microtype}

@N3buchadnezzar now installing :)

2:52 PM

@clabacchio I've written an answer for you. Please: never present yourself as "Rossi Mario". And, if possible, write your name on the left and the advisors' on the right. You are the main character in your thesis, not your advisors.

@egreg Heh, actually it's a template, but I can fix that

thanks anyway!

@N3buchadnezzar ok, microtype shrank the text :)

now the characters per line are 80

@clabacchio It's a terrible template. Wrong under many respects. Alma Mater should know better. But, of course, you're simply engineers. ;-)

@egreg well it's from computer science IIRC

@clabacchio Not much difference. ;-)

@egreg with the Rossi Mario stuff you mean that I should put the name first?

@egreg it's a HUGE difference!

2:56 PM

@clabacchio Yes, always

@egreg good to know :) I miss so many small things

but it'll take some time to go through your answer :)

@egreg actually, before using it...do you have some sort of template or suggestions?

@clabacchio One should be given by your university...

@egreg: The name placement was always something that intrigued me. I remember to see old letters from the Italian government where the family name was in front of the given name.

@clabacchio It's customary to invert the names in rosters, but it should be preferable to add a comma between them, in this case. This is not a roster and your name is Claudio. If a student presented me a thesis with inverted names I'd put it in the trash can. :)

@clabacchio Each university usually have a very strict layout for their thesis...

2:59 PM

@PauloCereda Bureaucrats.

@N3buchadnezzar nope, .doc :)

@clabacchio Package frontespizio, of course. :)

@egreg I thought so. :) They are not good at indexing, aren't they? :)

@egreg Yay! :P

@egreg just to say that I love to get suggestions directly from a prof. :)

@clabacchio Then you go to a s**y university =) Also see here tex.stackexchange.com/questions/326/…

@clabacchio latexforhumans.wordpress.com/2011/03/10/…

3:01 PM

@N3buchadnezzar the bureaucracy sucks here

but some things don't

@PauloCereda They want to tell what consideration they have for you: minus quam…

anyway my thesis has been the first serious document for which I've used LaTeX, and I've learned so much!

@egreg Oh, just like our beloved bureaucrats here. :D

Kannappan Sampath

Hello folks!

@egreg nice! but can I use it both for the cover and the titlepage?

I mean, the one inside

3:11 PM

@PauloCereda any working solution is fine I think :)

given that it's needed

:)

@tohecz I'm still trying to figure out how to generate only one file, but I'm not versed in PDF stuff. :)

@clabacchio The PDF version should have only one frontispiece. For the bound copy just print it twice.

@PauloCereda ... run pdftk afterwards?

@egreg but my thought was that inside it was centered like the rest of the text

so as a right page

3:13 PM

@clabacchio Why?

what-if.xkcd.com/1

4

@tohecz Oh! :)

@TorbjørnT I just read that, it was very nice =)

@TorbjørnT Oh my! :D

My friend has sent it to me earlier today, it's hilarious!

3:15 PM

@clabacchio The golden rule in Latex is Do not mess with how the document should look. You take care of the writing, and latex makes everything nice.

@egreg it looks nicer? :P

@clabacchio Not at all. Look at book frontispieces.

@egreg no, I mean the one inside

sorry I'm not experienced, just guessing

and trying to understand the reasons

@clabacchio It's the same: either it's asymmetric, or it's symmetric and centered on the page.

@egreg fair enough

3:20 PM

@JosephWright Ah, that makes sense.

@N3buchadnezzar nice, or sometimes horrible, but either way you should not argue with it.

@egreg is the frontespizio package compatible with english?

my thesis is in english

@clabacchio It's language independent: just change the keywords; there's no hyphenation involved, of course.

@egreg sorry for the ignorance, but I see fields like \Università...how are they translated?

with babel?

@clabacchio Section 4 of the documentation.

3:30 PM

@egreg heh, I'm still at the first

@egreg would you suggest beamer for the presentation?

@clabacchio Why not? :)

@egreg well, I don't have much time to learn

@egreg the best thing is that I don't have to worry about compatibility

and I like it

@egreg sorry, I was also struggling with a thing

I've been told that the supervisor must be addressed as "Chiar.mo Prof."

Is it the right thing? How does it translate to English?

@clabacchio I've added a possible code for frontespizio. There's a note in the documentation about the Chiar.mo. It obviously hasn't an English counterpart.

@egreg so, just use Prof.?

@clabacchio Right.

3:43 PM

@egreg great :) now I leave for home, be right back in 15 minutes

For the non Italian here: "Chiar.mo" is an abbreviation for "Chiarissimo", which means "most famous".

The university rector must be addressed to as "Magnifico Rettore".

@egreg is that what it means? I thought something like "Bright"

The latin etymology of the word is "who makes things bigger and better".

in the sense of a sharp mind

@clabacchio Latin "clarus" is "famous"; literally "in the light".

4:07 PM

@egreg I don't need expandafters if I use g@addto@macro do I (I generated the image shown at least?)

@DavidCarlisle Yes, there's "Comment 3" in all lines.

\g@addto@macro doesn't perform expansion

well yes there is that:-)

@egreg I think I wrote g@addto@macro:-)

Comes of answering tex questions with one hand while doing the day job (xml + fortran + c#) with the other

I don't suppose \expandafter{\the\c@comment is pukka latex but oh well...

back

2 hours later…

Brent.Longborough

5:53 PM

TeXLive 2012 is now "in production" in this corner of Wales. It took three attempts, but only due to a problem between the keyboard and the chair. W00t!

@BrentLongborough Keyboard and te cahair wut?

Brent.Longborough

@N3buchadnezzar In case you hadn't realised, the problem that lives between the keyboard and the chair is myself.

I thought there was a conflict between your chair and your keyboard, like they had started a small war or something.

Brent.Longborough

@DavidCarlisle Fortran and C# -- there's a heady mixture! I get my kicks, occasionally, with Haskell and Mercury Autocode :)

@N3buchadnezzar No, it's not original, though. A standard help desk problem close comment is "PEBKAC"; "Problem Exists Between Keyboard And Chair"

@BrentLongborough Yay! Mine is ready to be deployed too. :)

Brent.Longborough

6:07 PM

@PauloCereda Go for it! Don't forget to back up your TeXLive2011 tree first, and to copy over your texmf-local tree if necessary

@PauloCereda (Conselhos da vovo Brent)

@BrentLongborough Ah I made some backups, just in case. :)

@BrentLongborough LOL why does this remind me of the kid's series Rá-tim-bum? :)

Brent.Longborough

@PauloCereda Good luck!

@PauloCereda OK, you can call me Dona Benta, if you like...

@BrentLongborough Ah good memories! Sítio do Pica-pau amarelo. :) Or Tia Anastácia. :P

Brent.Longborough

Oh, yes, Yellow Woodpecker Farm!

@BrentLongborough :D

Was this show ever broadcasted outside Brazil?

Brent.Longborough

6:11 PM

@PauloCereda I don't know; I only ever saw it in Brazil, when my kids were that age.

I was just doing my "translate at the foot of the letter" thing.

hehe :)

One of the nicest series ever made here. :)

@Brent: I don't know if you remember "TV Colosso". :) I once saw it (recently) in a French channel (dubbed in French too!).

Brent.Longborough

@PauloCereda Yes, I do, vaguely.

@BrentLongborough I can't remember much of it as well, but there were dogs. Lots of them! :D

Brent.Longborough

@PauloCereda Yeah, that's right!

6:32 PM

@BrentLongborough :)

Q: Triangular region in Tikz

I need to plot a triangle with vertices (0,0), (1,2), (0,3) with x & y coordinate axes (and labels), and tick marks on the axes. How can I accomplish this in TikZ. My code is: \begin{tikzpicture} \draw[->] (-5.0,0) -- (5.0,0) node[right] {$x$} coordinate(x axis); \draw[->] (0,-5.0) ...

What is up with the answer from Christian Feuersänger ? Perhaps he answered the wrong q?

7:28 PM

TeX Live 2012 in PT-BR! Yay!

Brent.Longborough

@PauloCereda Yay indeed! With all the diacritics...

Ýàÿ!

@BrentLongborough :) It was quite tricky to translate those messages. Some things are easier to explain in English. :P

@BrentLongborough Vîvãáàä! :)

Brent.Longborough

@PauloCereda I can imagine. I think Portuguese is 20-40% longer than English, but when to need to translate technical stuff it's even worse.

@BrentLongborough Indeed, it's a nightmare! :) I volunteered to translate the TeX Live guide to Portuguese, but I couldn't even finish the first page.

Brent.Longborough

@PauloCereda Is that still an open project?

Yes, I agree, the first page is quite hard...

:)

As are the rest

7:40 PM

@BrentLongborough It is, maybe for TL2013. :) I contacted Karl about it. I asked if there was any work in progress for a PT-BR translation. He said that there were no volunteers to do it, so I offered my help. :) Sadly, I had less than a month to translate the document, if I wanted it to make into TL2012. :)

Brent.Longborough

How's it structured? I see there's an HTML version. Or is it just to translate LaTeX?

Or is it DocBook or such?

It's LaTeX. The Makefile has a TeX4HT task too. :)

Let me find the repository. :)

Brent.Longborough

Yes, I just looked at the HTML source - TeX4HT

@Brent: found it: tug.org/svn/texlive/trunk/Master/texmf/doc/texlive

We basically copy texlive-en into a similar texlive-ptbr structure. :)

Thankfully I can svn only that part. :)

@BrentLongborough So you speak Portuguese?

Brent.Longborough

7:51 PM

@PauloCereda Hmm, svn. I totally migrated to git over 4 years ago...

@JosephWright Yes, my second language. I lived in Brazil for 20 years

@BrentLongborough Me too. :) I have those tools still available. :)

@BrentLongborough Ah, this makes sense!

Brent.Longborough

@JosephWright Brazilian Portuguese, of course, not Lusitanian

@PauloCereda Have you tried SmartGit?

@BrentLongborough Which aren't mutually comprehensible, just like BrEn and AmEn. :)

@BrentLongborough Wow! I had no idea about this tool! It seems very nice!

Brent.Longborough

7:55 PM

@egreg Yes, even more so...

@PauloCereda Definitely worth trying. The index editor and the conflict solver are really nice, the GUI in general "fits nicely in my hand", like the hilt of a sword

@PauloCereda Not to mention the log viewer

8:13 PM

@BrentLongborough I'll really take a look. :) Sounds promising.

Brent.Longborough

I'm sure you won't be disappointed

TL2012 up and running. :)

@PauloCereda It's generating the formats.

Even euptex. :)

And two updates with tlmgr. :)

8:30 PM

@egreg Yay! :)

Good evening!

@tohecz Evening! :)

@PauloCereda Sorry for being that late, but with EP and headphones, I found a new way of procrastination

@PauloCereda Done. First compilation succeeded. :)

@tohecz :)

@egreg I'm finishing running tlmgr. :) No updates here. :(

8:32 PM

@PauloCereda But I've been using it for some weeks at the office.

Maybe the current mirror is not totally updated.

@egreg Ah you are my hero. :)

@PauloCereda I tried yesterday and the test version had silently changed to final with the last binaries update. For tlmgr there may be one day or so of delay, it depends on the mirrors.

@egreg Ah I see. :)

@PauloCereda The boing persists even if I relaunched Safari. Mystery.

@egreg Mystery indeed. :) I'll try with my Safari and see if I get any clues. :)

user image

Yay, Portuguese!

I mean, Portugoose. :P

8:47 PM

@PauloCereda After having broken TeX Live, now it works. :P

@egreg Oops. :P

@PauloCereda But it was Norbert's fault, of course. He speaks German, English, Italian, perhaps also Japanese, but Brazilian Portuguese failed him.

Wow, my number of "Nice answer" badges is palindromic.

One out of 8.31, not bad. :)

@egreg Norbert wrote a fantastic implementation to make TeX Live support region codes (I asked in the list about this support; I was afraid of having only one "official" PT translation when we have language diversities around the globe (PT from Brazil, Portugal and some African countries). But thankfully the code was fixed in time. :)

@egreg Yay, congrats! :)

a >> b, where a is the number of nice answer badges from egreg, and b is the sum of all badges from Paulo. :P

Sorry, I don't know how to pass the time: Čajkovskij violin concerto is happily ending. Abominable. ;-)

Now there's an Irish composer, John Field. Nice.

:)

8:59 PM

@PauloCereda But Alan's not here. :)

Unfortunately, the next piece is Dvořák's. :(

@egreg I wonder if the result of the intersection between both Alan's and your iTunes library is an empty set. :P

@egreg You have some problem with Dvorak? I'm actually just listening his Biblical Songs

@egreg I like some pieces. Not that much though. :)

@tohecz Simply that I still have to find one piece of his that I like.

At least I can write his name right. :)

@egreg ;) I don't say his music is something everybody must like, I got the CD with his Biblical Songs after my dad found out I don't know what they are

9:04 PM

I can't. :(

@PauloCereda Can't what? Spell "Dvořák"?

@tohecz Yes. :) The closest I can get is "Dvorák". :)

@PauloCereda Writing it is one thing, saying it is another. The "ř" is almost impossible.

You need Czech or Slovak keyboard I think ... or copy-paste

@tohecz On the Mac, US Extended keyboard layout, it's "Alt-v" and then "r"

9:06 PM

@egreg Well, I started visiting a logopedist recently to learn to pronounce "r" correctly, with "ř" being the next step

@egreg and your number of all Bronze badges as well! :o

@tohecz The combination "př" is very peculiar.

@tohecz I had to look up logopedist!

@egreg Many things in Czech language are peculiar

like "scvrnkls", but I believe we've discussed this before here...

or "strč prst skrz krk"

@JosephWright There's no need of logopedists in UK, everybody speaks as they like. :)

2

and instead of "The quick brown fox jumps over the lazy dog" we have "Příliš žluťoučký kůň úpěl ďábelské ódy"

2

9:10 PM

A vowel, my kingdom for a vowel. :) In Portuguese, we cannot have syllables without at least one vowel.

@egreg :-) I'm sure amongst friends that's what they call themselves, but in common parlance one would say 'speech therapist' or (I suspect) 'going for elocution lessons'

@tohecz Wow, my favorite line from now on! :D

Do you know the meaning?

I have no idea. :(

well, it'll be tough to translate into English, gimme a minute

9:12 PM

@tohecz Is "kůň" the horse?

@egreg yep

the biggest issue is the word "úpěl"

@tohecz I remember a restaurant in Malá Strana

well, it can be "Příliš žluťoučký kůň úpěl ďábelské ódy" = "Over-yellowish horse was moaning devilish odes"

btw, on the Czech keyboard layout, you have to write number with shift, without shift, you get +ěščřžýáíé instead of 1234567890

@tohecz Actually I remembered wrong. But the surroundings are very nice: it's in Cihelná, where you can go to the river and look at Charles bridge. There's a very old house, XVI century, I believe.

@egreg So it's next to Kafka museum?

9:21 PM

@tohecz I guess so. There's a garden nearby. Maybe 100m from Malostranská metro station

yeah, I know that area, I just never remember the street names there

@tohecz I love Malá Strana, of course.

I'd love to visit Prague. :)

@egreg I like it too, sensing the history there

But the best is go watching the sunrise to the Petřín hill and park, seeing the long lines of street lights on the river banks switching off, and the Prague waking up to another morning, everything yet calm and getting ready for the busy day.

@PauloCereda From the square where that metro station is, one can climb to the castle: there are magnificent gardens below those stairs, because many rich people had their mansions in that zone. Then you can visit the castle and descend along Nerudova or remain on the hill and go to Petřín to have a great look at the town.

9:32 PM

@PauloCereda It's not that far from you ;) * sacrasm *

@tohecz Another great moment is the night on Charles bridge (in January, when there are few tourists), with the castle up there.

@egreg yep, and dozens and dozens of these.

I even like walking the Nuselský bridge

I always go to greet old Charles at the end of the bridge.

lol

@tohecz There's a great view also there.

9:36 PM

yes, I like several things there: the fact that there're only 6 rows of houses below the bridge, the trains and trams, the sight on the Eastern part of Prague,

and last but not least, that I can laugh to the car drivers in traffic jams :D

@egreg, @tohecz: I'd love to include Czech Republic in an European tour. :)

@PauloCereda you should. I even have few tips on very cheap and quality hotels

(btw, can I get a list of all messages I starred and all my starred messages?)

@tohecz We were once in a nice hotel in Kampa (in the winter tours) because the university residence was closed. Otherwise we had (in winter) quite a good accommodation in that residence in Celetná. :)

@egreg Yeah, I know about that

For the non cognoscenti: Celetná is one of the most ancient streets in Prague, from Old Town Square to the Powder Tower.

The university residence is a XVI century hall.

9:46 PM

Well, there's a *** hotel with prices 29 EUR single breakfast incl. (23 EUR excl.), which is 25 minutes from the town centre

@tohecz Really? Very interesting.

Our university graduation ceremonies are in the Bethlehem Chapel, found 1391

@egreg hotel-globus.cz/en

@tohecz Mine was in the main university hall, founded 1222. :)

@tohecz Bookmarked, thanks

@egreg cool

@egreg you're welcome. Just remember: their marketing strategy is "every night, every room occupied" so you have to book the room in a long advance

@tohecz Betlemská is a very nice church indeed, in a very good neighborhood.

9:53 PM

@egreg indeed, and very representative as well

Sup homes?

@N3buchadnezzar once more and slowly please, I can't understand you if you speak this fast...

I suppose "sup" is "what's up"?

never mind, I got to go anyways, so good bye!

@tohecz I was casually strolling through the large interwebs, and happen to stumble upon this humble abode. While slowly removing my top hat and nodding I uttered the words: Sup homes?. As a casual greeting for the gentlemen in the room. Although one of them looked somewhat perplexed by my greeting, I was sure my greeting was well approved. So I continued my stroll.

2

@N3buchadnezzar please don't take me wrong, as I said here before, informal English is a big problem for me and I want to improve it, here is where the stupid questions come from

now I really got to go, so good bye/night

@tohecz Good night! :)

10:01 PM

@tohecz Sleep tight lad.

@PauloCereda How is it going?

@N3buchadnezzar Fine. You? :)

Good, it is hot!

How hot is hot? :P

Its pluss degrees!

:p

oooh! :)

10:09 PM

I think it is about 20, but it is midnight here so..

@N3buchadnezzar We have 27 now outside. But the air conditioner helps. :)

egreg, do you know how to make the coloumns in a table less wide?

I know this questions have been answered many times before, but I can not seem to find it now.

@N3buchadnezzar Would you kill me if I say that we have 20ºC now and it's a little cold for us? :P

@PauloCereda Come to norway during the winter, -5 is a little warm for us :p

@N3buchadnezzar LOL

10:12 PM

I am using S columns so the p{2cm} is not an option. I did try the tabubular* but that only fitted the table not the entries.

10:31 PM

@egreg Any hints ? pastebin.com/qVAcz74G =)

@N3buchadnezzar tabular* doesn't do anything if you don't put stretchable space between the columns.

@egreg It does fit the table to the pagewidth though

I tried adding @{} but this leaves to little space

@PeterGrill: about your feedback question (tex.stackexchange.com/questions/62781/…) - great question, by the way! - I have a suggestion too. :) I like R. Schumacher's idea, and my suggestion is actually along these lines: how about using a StackOverflow clone? You could use votes/downvotes, "questions and answers" to represent the reviewers feedback: meta.stackoverflow.com/questions/2267/stack-overflow-clones

@N3buchadnezzar Try this

\begin{table}[h]
\centering
\addtolength\tabcolsep{-3pt}
\begin{tabular}{c *{11}{S[table-format=+3.1]}}
\toprule
$x$ & -3   & -2 & -1   & 0 &  1   &  2 &  3   & 4 & 5   & 6 &  7   \\ \midrule
$y$ & 10.5 &  6 &  2.5 & 0 & -1.5 & -2 & -1.5 & 0 & 2.5 & 6 & 10.5 \\
\bottomrule
\end{tabular}
\end{table}

Thanks, I am sure that works! Just a quick question, what does the "table-format" do?

I tried adding that and changing the numbers, but I did not see much difference.

I figured it out =)

@PauloCereda That is a good suggestion. I see a great advantage to providing the different files over the internet as then they are always the current version, but not sure I understand how to implement it.

@PauloCereda @PauloCereda @egreg The intersection of our iTunes libraries is approximately egreg's library - all the opera.

@AlanMunn You mean the opera, which approximately means Mozart. :)

@egreg :)

@AlanMunn LOL

@AlanMunn The radio has now Chopin's first piano concerto. I can listen to it. But I don't like it. However it's high music compared to Čajkovskij. :)

@PeterGrill I also thought of some sort of Conference Management System (I remember OpenConf). It might need some adjustments. :(

@egreg This one is in my iTunes library. :P

@Alan: I have Les Misérables, but it's a musical, not an opera. :P

11:34 PM

@egreg I'm not a big fan of the Russian Romantics; I do like Chopin, although the concertos are a bit over the top.

@PauloCereda I suspect that @egreg and I agree completely on musicals. :)

@AlanMunn Uh-oh. :)
