@ChristianHupfer and I decided that I don't want to pay for W8 and not have the chance to use them.

Paulo Cereda

@yo' and I forced Dell to not charge me for Windows because I don't want to use it. :)

yo'

@PauloCereda I could do that, too. The problem is, you don't safe anything. The Windows officially cost literally nothing if they are "in collection"

Paulo Cereda

@yo' At least in here, it costs a lot. :)

David Carlisle

@PauloCereda but it's worth it, to get paint

yo'

@PauloCereda well, the vendor of course pays f@#$%^ lots, but because he's a MF, ...

Christian Hupfer

12:09 AM

@yo': It wasn't my notebook, so it was not my 'Money for nothing' :-P

Paulo Cereda

@DavidCarlisle sudo dnf install pinta :)

yo'

@PauloCereda dnf - did not finish?!

Paulo Cereda

@yo' nope :)

Christian Hupfer

@yo': duck's no fool

yo'

I need an advice guys

David Carlisle

12:12 AM

@yo' ?

Christian Hupfer

@yo': We hear, my son ;-)

yo'

I try to solve the Rubik's cube. I've got to the "three corners" problem. Now: Should I look up the solution on teh internetz, or should I tease myself and try to figure it out?

Christian Hupfer

@yo' A clear and definite: Unsure ;-)

Paulo Cereda

@yo' How much is the situation affecting you? :)

David Carlisle

@yo' I solved it myself when it first came out, had to lock myself away for a few days:-)

Christian Hupfer

12:14 AM

@DavidCarlisle: no comment

yo'

@PauloCereda well, not at all, just that I won't sleep until I solve it :)

@DavidCarlisle seriously?!

David Carlisle

@yo' more or less, I probably wasn't literally locked in, but I may possibly have skipped a lecture or two:-)

Paulo Cereda

@yo' ^^ solved by bruteforce. :)

cfr

@ChristianHupfer I figured you must. Well, actually, I haven't. I'm hoping it goes out of fashion before I'm forced to deal with it!

yo'

@PauloCereda I wouldn't need the hammer; in most cubes, there's a piece that can be removed more eaasily than the rest, and this is where you start :) (it's there for cleaning, repairs, lubricating and tension adjustments if you have one of the fancy ones, ...)

Christian Hupfer

12:18 AM

@yo': Once upon a time ...in the late 70s/early 80s, when no TikZ was at hand... there was Math Student called David who dared to miss some lecture... This did nothing good to him since he was damned to work with the most evil operating system ever invented... MS Windows. ... a sad fairy tale. The End.

yo'

@DavidCarlisle well, the seriously was to the I solved it

David Carlisle

@yo' yes, I used to be able to do it in around a minute, it takes me a lot longer now, and seems that anything over 5 seconds is considered slow these days;-)

yo'

@DavidCarlisle not quite; the official WR is 5.55 AFAIK, by that cool Dutch guy

Christian Hupfer

@PauloCereda: 'Disassembling' the cube is not solving

Paulo Cereda

@ChristianHupfer If inside a black hole there's infinite energy, a dissassembled Rubik's cube could be tossed inside it and be solved. :)

David Carlisle

12:24 AM

@yo' I've watched a lego robot do it in around that sort of time, quite impressive:-)

Christian Hupfer

@PauloCereda: Perhaps, but you've won't never get information about it:-P... Unless a virtual Rubik cube will appear outside :-P .... Rubik Cube radiation :D

yo'

@DavidCarlisle well, a LEGO robot can use the computer to minimize the number of steps down below 20

Paulo Cereda

@ChristianHupfer I could use a fishing rod, as I read some wacky researcher once suggested. :)

Christian Hupfer

@PauloCereda: In 'Mad Cap Physics Today' ? :D

David Carlisle

@yo' yes it spends longer thinking about it before it starts moving, which isn't the usual human way. although I suspect those sub 10sec times are doing something similar, that video showed them looking and if you do the usual face at a time approach it certainly takes more moves

cfr

12:27 AM

@PauloCereda Arch. I did install Ubuntu at one point. Though only out of desperation. I never planned to use it. The installation failed spectacularly, but I didn't actually care. Its installer was Evil - just I needed its particular brand of evil at the time.

yo'

@DavidCarlisle well, I do a layer at a time. Those guys have, for each pair to shift, and algorithm that does it without breaking this or that configuration :)

Paulo Cereda

@ChristianHupfer I don't remember exactly where, but it was on the NP=P question. Seriously, the guy was suggesting tossing a computer inside a black hole (or something along these lines) tied to some sort of string then pulled back. I'll try to find the reference. I was so enraged that day. :)

yo'

I mean: construct the top face, add the adjacent middle edges, then arrange the edges in the bottom, and then (I can't do this) solve the 3-corner problem :)

Paulo Cereda

@cfr How nice, great to know you use Arch. :) I say, pacman is a god amongst men -- one of the best package managers ever known to mankind. :)

David Carlisle

@yo' anyway if you can solve it all but three corners you're nearly there

Christian Hupfer

12:28 AM

@PauloCereda: I'm thrilled by this kind of reasoning (of that 'researcher')

yo'

@DavidCarlisle yep, but so far it was really simple :p

anyways, a small disappointment: I solved a level 6 Hanayama in 15 minutes :(

Paulo Cereda

@ChristianHupfer I'll find the reference and forward it to you. I was really, really shocked.

Christian Hupfer

@PauloCereda: As soon as you can do it, no hurry!

Paulo Cereda

@yo' I solved a puzzle in 10 minutes when the box says "2 to 4 years". :)

yo'

@PauloCereda LOL I wuv you

Paulo Cereda

12:30 AM

@yo' <3

@yo': no news from the Czech mail? I so want my musicsheet to arrive to you. :)

Christian Hupfer

@yo': wuv?????

Paulo Cereda

Oopsie I told the secret.

yo'

@PauloCereda no news :-(

Paulo Cereda

@yo' Let's wait then. :(

cfr

@PauloCereda 'How nice' sounds rather sarcastic in British English. The kind of thing you say when somebody has told you a long story about how they lost a sock once but eventually found it in their sock drawer.

@PauloCereda pacman is fantastic. pacmatic is even better.

yo'

12:32 AM

@ChristianHupfer a childish way to say to "love" when speaking to your duck :)

Paulo Cereda

@cfr Really? Oh my, sorry! I really meant it.

Arch looks quite interesting.

yo'

@cfr pacman? cotondoux.com/en/…

Paulo Cereda

Pacman master = pacmeister?

:)

cfr

@PauloCereda It's OK. I figured. In American English, it would not sound sarcastic, either.

Christian Hupfer

@yo' Say no more ... ;-) @PauloCereda

Paulo Cereda

12:34 AM

@cfr I wanna sound British. I sound like a Latin redneck. :(

@ChristianHupfer nudge nudge

cfr

@PauloCereda Arch is excellent. However, getting my machine to play nicely with GPT disk and EFI boot was... 'interesting' would be one word for it, I suppose.

yo'

@PauloCereda well, I hang out with Britons, and I think I get something from their English, which I really like :)

Christian Hupfer

@PauloCereda: 'I've written a sketch' :-D

yo'

@cfr another British thing: "interesting" for "damned"

cfr

@PauloCereda @yo' Welsh I am.

yo'

12:35 AM

@cfr know I do :)

Christian Hupfer

@yo'da :-P

Paulo Cereda

@cfr I used Slackware for a long time. That's a sadist distro. :)

@ChristianHupfer LOL

@cfr I'm a duck. :)

yo'

@ChristianHupfer I didn't get this ping... :)

cfr

@yo' Welsh allows you to move things around more than English. And this affects the way English is spoken in parts of Wales (even by non-Welsh speakers).

Christian Hupfer

@PauloCereda: I am tired ... and should go to bed

cfr

12:37 AM

@PauloCereda I used Debian for a while. Try finding something which ran on a PPC Mac.

yo'

@cfr well, like Czech, is not fixed the word order, speak so you can as you wish

egreg

@PauloCereda Chuck Norris only uses Slackware. He just orders it to install and to work.

yo'

however, it changes meaning slightly, you stress things buy changing the order

Christian Hupfer

@egreg: That's rather SlapWare ;-)

yo'

@egreg Chuck Norris can reach the end of the Turing machine tape

@PauloCereda bbs.archlinux.org/viewtopic.php?id=131149

Paulo Cereda

@cfr Oh my!

cfr

@yo' Yes. It changes the emphasis in Welsh, too. Also, you have to be especially careful with the third person singular in some senses, since the form of the verb 'to be' depends on the order.

yo'

12:42 AM

@cfr wow! Can you give a simple example? He is a duck, for instance :)

Paulo Cereda

@egreg When I was in my older lab, we just got brand new workstation. My first huge monitor! While people with big desktop areas (Windows, Ubuntu), I had a huge black screen (>23") with a blinking white cursor. :)

Slackware was impressive. And I even had Gnome 2 with it!

Christian Hupfer

@PauloCereda: Virtual Console? ;-)

Paulo Cereda

@ChristianHupfer Init 3. :)

Graphic mode was for the weak. :)

Christian Hupfer

@PauloCereda: \ifnum5\init 3 :D

yo'

@PauloCereda it still is. yum install lynx :D

Paulo Cereda

12:44 AM

@ChristianHupfer Aha! Slackware's graphic mode was 4!

Don't ask me why. :)

@yo' LOL

Christian Hupfer

@PauloCereda: Really? ;-)

yo'

@PauloCereda I hope you know this program ;)

Paulo Cereda

@yo' I know! My older lab didn't have a VPN service, so I accessed my machine from home via ssh, connected to the IEEE portal via lynx and download the papers I wanted. :)

yo'

@PauloCereda that's what I do with Springer :)

Paulo Cereda

@ChristianHupfer Yep. :)

@yo' ooh!

cfr

12:47 AM

@yo' I get confused easily, especially when I think about it. Just checked, though. Mae e'n hwyaden. (He's a duck.) Hwyaden yw fe. (Duck is he.) Fe sy'n nofio. (He is swimming.)

Christian Hupfer

@PauloCereda: I've extended the number of virtual consoles to nine ... And changed the greeting to 'I'm Virtual Console %d of Nine' ... Funny if %d is 7 :D

yo'

@cfr different "he" for object and subject, too, as I see :)

@ChristianHupfer LOL, one nice StarTrek meme :)

Paulo Cereda

@ChristianHupfer geek people. :)

Christian Hupfer

@PauloCereda: I could not resist .... ;-)

cfr

@yo' Oh. Well not really. I could have used 'e' everywhere, sorry. But I don't think I could have used 'fe' in the first one. At least, it feels wrong.

@yo' 'ef' is really 'he' but that's written, formal. 'e'/'fe' in the South. 'o' in the North.

Paulo Cereda

12:50 AM

yo'

@cfr nice and complicated :)

Paulo Cereda

@yo': A friend of mine wanted to give me one of these. ^^

Christian Hupfer

@PauloCereda: You daily duck drug? ;-)

Paulo Cereda

@ChristianHupfer Surprisingly, clonazepam has the inverse effect of caffeine. :P

cfr

@PauloCereda Wow. Usually medicines here are quite small. We call them 'pills'. No handles to swallow at all!

Paulo Cereda

12:51 AM

@cfr :) It's a nice mug. :)

yo'

@cfr sorry, no, you don't understand it. The mug is for dosage; you fill it with Clonazepame and then swallow it all

cfr

@yo' Ah.

Christian Hupfer

@PauloCereda: That's what my students say about my teaching too .... nothing new to me :D

cfr

@yo' But: Nofio mae e. (He is swimming.)

yo'

@cfr "Swimming is he." ? Well, in Czech, you'd say simply: "Plave."

Paulo Cereda

12:54 AM

@ChristianHupfer :)

Christian Hupfer

@PauloCereda: Ah, it's from Bayer

cfr

@yo' Sure.
yo: The duck went for a walk.

Paulo Cereda

@ChristianHupfer I think so. Bayer owns almost everything.

cfr

Paulo: No. Swimming he is.

Paulo Cereda

Mae fy hofrenfad yn llawn llyswennod.

@ChristianHupfer ^^

Christian Hupfer

12:56 AM

@cfr: I think I know now where Yoda-speak has it's origin :D

yo'

@PauloCereda one my Czech friend here in Paris is Bayer's salesman

Paulo Cereda

@yo' Really? Wow.

cfr

@ChristianHupfer Hmm...

Christian Hupfer

@PauloCereda: Yes, they even own a football team

Paulo Cereda

@ChristianHupfer o.O

cfr

12:58 AM

@yo' Not really 'swimming is he', though. I mean, literally word by word. But the verb comes before the person normally. That is, unless you are switching stuff. You could say 'he's swimming' in one word in formal, written Welsh. But you'd lose the emphasis if you did that. You couldn't say 'He's swimming' that way.

yo'

@cfr ah, that's really similar to Czech.

cfr

@yo' Yes?

Paulo Cereda

Dear friends, time for me to go up the wooden hill to Bedfordshire. :) Good night!

Christian Hupfer

@PauloCereda: Bye... ah damn, you're already gone...

yo'

@cfr well, omitting everything but the verb leaves it in a simple informative tone.

cfr

1:00 AM

@PauloCereda Nos da.

@yo' Nofia. (He/she is swimming/swims/will swim.)

Christian Hupfer

I am off too... have a nice time

cfr

@ChristianHupfer Nos da.

yo'

@PauloCereda I should go, too

cfr

@yo' You wouldn't say it though. You'd at least add a pronoun. And if you said it, it would mean future tense.

yo'

@cfr well, plave is the Czech form :)

cfr

1:02 AM

@yo' Nos da.

Christian Hupfer

@cfr: Thanks, you too ( I hope, it's 'sleep well' or 'well sleep'... whatever ;-))

cfr

@yo' He or she? Present and future.

yo'

@cfr ah, well, in Czech, plave is present, while poplave is future :)

@cfr any of them, the present doesn't distinguish sexes, only the past

cfr

@ChristianHupfer Nos=night; da=good. (It 'should' mutate but doesn't.)

Christian Hupfer

@cfr: Thanks ;-)

cfr

1:05 AM

@yo' Interesting. The formal drops the pronoun if it isn't necessary. It is also less picky about tenses. However, there are some tenses which are only ever used in formal Welsh. Actually, one is pretty much reserved for Biblical Welsh at this point.

yo'

@cfr that's known in English, too :) (with thou art in heaven)

cfr

@yo' Is that a distinct tense? I always assumed it was just a fancy 'are'.

yo'

@cfr not a distinct tense, it's just proper 2nd person sg

cfr

@yo' Is 'thou' familiar or formal? I thought it was formal, but that seems odd.

yo'

@cfr it's unused, that's the most important thing. But other than that, it's more familiar; it's what you'd use with a friend, like 5 centuries ago, amybe more :)

cfr

1:15 AM

@yo' Thanks. Just been reading OED. I always thought the contrast was with thee. But it isn't. It is with you. So Thou art... is familiar, which makes sense. At least, other languages seem to use the familiar for God.

OED quotes: 'Though I Thee Thee, and Thou Thee, I am no Quaker.'

yo'

@cfr yep, well, all other European languages use it, AFAIK :) As well, in most languages, the "t" form is the familiar one, and the "y/v" form is the formal one

T–V distinction

In sociolinguistics, a T–V distinction (from the Latin pronouns tu and vos) is a contrast, within one language, between second-person pronouns that are specialized for varying levels of politeness, social distance, courtesy, familiarity, age or insult toward the addressee. Languages such as modern English that, outside of certain dialects, have no syntactic T–V distinction may have semantic analogues to convey the mentioned attitudes towards the addressee, such as whether to address someone by given or surname, or whether to use "sir" or "ma'am" in American English. Under a broader classification...

cfr

@yo' Well, I was trying to make a thee/thou distinction so the 't' didn't really help.

@yo' Welsh has a t-ch distinction, I guess.

yo'

@cfr ah, thee is the object form of thou (as him is of he)

cfr

@yo' Yes. I think that is what OED said but in fancier language. But that seemed to be the gist.

yo'

@cfr English has 2 cases: subject and object (Czech has 7: subject, 5x object, and vocative)

cfr

1:23 AM

@yo' Czech would! I've never understood about cases, though. Other than putting clothes in them.

yo'

@cfr cases are what allows you to construct sentences like "Ona jemu." ("She him." when translated literally.)

cfr

I'm not sure (modern) Welsh has any.

@yo' What does that mean?

yo'

@cfr Well, it would be an answer to a bit strange question: "Who have given the money to whom?"

However, you have better examples: "Já jsem si to tím sám prostrčil" -- literally translated: "I have self it through_it myself put". The "through_it" is actually just "it" in 7th case.

cfr

@yo' In English, no short response is really natural. 'Her to him' might be closest. (I'm sure that's ungrammatical but 'she to him' sounds weird.)

yo'

It's difficult to explain I think, and I gotta go o catch some sleep :)

so good night :)

cfr

1:28 AM

@yo' Difficult to explain to *me*, probably ;.
Nos da :).

yo'

@cfr Dobrou!

ah, that's a nice example, actually. "Dobrou" means "good", but in the 4th case used in "to wish <something>". Whereas "Dobrá" means "good", but it's the 1st case and means more like "ok" or "I agree".

and we even omit the word "night" in the sentence often :)

Christian Hupfer

7:45 AM

Good morning

Christian Hupfer

8:53 AM

Good maen again

9:07 AM

@ChristianHupfer hello there

@ChristianHupfer well, I gotta go again, so bye :)

Christian Hupfer

@yo: See you

1010011010

10:00 AM

Morning. Surely a comprehensive list of LaTeX dimensions exists (beyond the pagelayout package), that also includes, e.g. table dimensions and package-specific dimensions.

Christian Hupfer

@1010011010: A question or a statement? ;-)

1010011010

@ChristianHupfer Good question, can I sleep a night on that? :-)

Christian Hupfer

@1010011010: As you like it :D

1010011010

@ChristianHupfer I'm looking for those dimensions, though.

Christian Hupfer

@1010011010: Something like \arrayrulewidth or \tabcolsep ?

1010011010

10:05 AM

@ChristianHupfer And so on, yeah. I have some poor numerical dimensions for my template. I'm looking to improve them for arbitrary page width.

Christian Hupfer

@1010011010: \the\mydimensionname shows you the length ;-) In conjunction with xprintlen package quite helpful...

1010011010

@ChristianHupfer I'm exactly looking to avoid the numerical dimension.

Christian Hupfer

@1010011010: For a quick comparison what goes wrong it's quite difficult to avoid them.

@1010011010: What is your specific problem? Width of tabular as such or the column separation ?

1010011010

Trying to stretch a colorbox across the width of my page, which I solved numerically now but I'd rather have some dynamic solution. Hold that thought while I upload some compilable example somewhere.

Christian Hupfer

@1010011010: Should be quite easy with tcolorbox...

1010011010

10:13 AM

@ChristianHupfer mega.co.nz/… This compiles to some example document. Looking to improve the dimensions for the tabular I used inside the tcolorbox (the one at the titlepage).

David Carlisle

@1010011010 why is that difficult? (what did you do that didn't work?)

1010011010

@DavidCarlisle I tried so many things that I lost track of what I actually tried, honestly. I'm baffled that this poses such a big problem.

David Carlisle

@1010011010 so am I:-) \colorbox is just like \fbox in terms of size

1010011010

I tried to make sure that the tcolorbox spans across the width of the text block. I've finally just decided to use 4.4\tabcolsep as some random dimension but it's hilariously poor for a solution.

Christian Hupfer

@1010011010: Just downloaded it, will have a look

David Carlisle

10:18 AM

@1010011010 \colorbox{blue}{\parbox{\dimexpr\textwidth-2\fboxsep}{\centering hello}} should work

@1010011010 why is \tabcolsep involved at all?

Christian Hupfer

@1010011010: Is it that logo stuff?

1010011010

It's about this:

\colorbox{palette2}{\vrule width 0pt height 5.8ex \begin{tabular}{>{\RaggedRight\arraybackslash}p{\dimexpr.33\textwidth-2\fboxsep} >{\centering\arraybackslash}p{\dimexpr.33\textwidth} >{\RaggedLeft\arraybackslash}p{\dimexpr.33\textwidth-\fboxsep}}
\includegraphics[height=8ex]{logo_uva.png}
&
%
&
\includegraphics[height=8ex]{logo_iis2.png}
\end{tabular}}}

That -2\fboxsep is not supposed to be there, obviously.

@ChristianHupfer Yeah.

David Carlisle

\vrule width 0pt height 5.8ex isn't doing much useful in combination with a vertically centred tabular. You could fix your table column widths, but are you just putting a parbox next to an image? you don't need a tabular for that, so the whole thing seems over complicated

@1010011010 oh you have no text, it's just two images?

1010011010

@DavidCarlisle In some cases I'll be using three instead of two logos, that's why I chose for tabular as a quick solution. If you know something better I'm open for ideas?:-)

@DavidCarlisle No text involved in the colorbox.

David Carlisle

@1010011010 a tabular is for aligning stuff in one row with matching stuff in the next row, a one row tabular can always be simplified just by removibg the tabular which isn't doing anything iuseful

\noindent\colorbox{palette2}{\makebox[\dimexpr\textwidth-2\fboxsep]{\includegra‌phics{}\hfill\includegraphics{}}}

Christian Hupfer

10:31 AM

@1010011010: If using a tabular, use \newcolumntype for the specification of the particular column types

1010011010

@DavidCarlisle Comes pretty close. Here the \vrule kicks in: I originally used it to get a slightly thicker edge of the colorbox. I can adjust that horizontally with e.g. hboxes:

\colorbox{palette2}{\vrule width 0pt height 5.8ex \parbox{\dimexpr\textwidth-2\fboxsep}{\hbox to 5pt{}\includegraphics[height=8ex]{logo_uva.png} \hfill \includegraphics[height=8ex]{logo_iis2.png}\hbox to5pt{}}}}

Still doesn't adjust the vertical edge, so I figured if I fiddled around with vrules I could still make it happen.

That is, the edges above and below the logos.

David Carlisle

@1010011010 the "edge to the colorbox" is \fboxsep set that to the value you want and it (I:-) will add the needed padding. No need for explicit empty boxes.

1010011010

@DavidCarlisle I thought that too, but even that didn't result in anything useful. It's the package mwe that changes all the \includegraphics to black boxes, right?

David Carlisle

@1010011010 no [demo] option to graphicx does that. mwe supplies some sample images like example-image-a that you can use

{\setlength\fboxsep{1cm}\noindent\colorbox{palette2}{\makebox[\dimexpr\textwidt‌h-2\fboxsep]{\includegra‌phics{}\hfill\includegraphics{}}}}

1010011010

\documentclass{article}
\usepackage{graphics}
\usepackage{mwe}
\usepackage[dvipsnames]{xcolor}
\begin{document}
\raisebox{3.5ex}{%
\colorbox{blue}{%
\fboxsep=5pt
\parbox{\dimexpr\textwidth-2\fboxsep}{%
\includegraphics[height=8ex,width=8ex]{example-image-a} \hfill \includegraphics[height=8ex,width=8ex]{example-image-a}
}
}
}
\end{document}

I'm probably misusing \fboxsep ? :-D

I was under the impression that changing \fboxsep would make that edge thing thicker?

David Carlisle

10:42 AM

`\colorbox{blue}{%
\fboxsep=5pt` I'd guessed you'd done that which is why I posted the comment above. You need to set parameters for a command Before using the command.

@1010011010 It would for any boxes in the scope of that setting, but you have no boxes in that inner group

1010011010

@DavidCarlisle Ah. I should've seen that myself. :/ Sorry. Thanks.

@DavidCarlisle Call me crazy but, what's going on here then? i.imgur.com/eU9xXDy.png?1 (I've used the looking glass to zoom in, as you can see it shows that the colorbox is still of larger width than \textwidth?!?!)

Assuming that the horizontal rules stretch across \textwidth (sounds like a safe assumption to me).

David Carlisle

@1010011010 oh the usual, we could summon up @egreg to give his favourite answer:-)

@1010011010 you changed what I suggested, changing \makebox to \parbox but more importantly adding two word-spaces after } inside the box.

Christian Hupfer

\newcolumntype{L}[1]{>{\RaggedRight\arraybackslash}p{#1}}
\newcolumntype{R}[1]{>{\RaggedLeft\arraybackslash}p{#1}}
\newcolumntype{C}[1]{>{\arraybackslash\centering}p{#1}}

\newlength{\logoheaderwidth}
\setlength{\logoheaderwidth}{\dimexpr\linewidth-6\tabcolsep}%

\newlength{\logocolumnwidth}
\setlength{\logocolumnwidth}{\dimexpr.3333\logoheaderwidth}%

\begin{tcolorbox}[colback=palette2,width=\linewidth,arc=0mm,auto outer arc,boxrule=0pt,boxsep=0pt,left=0pt,right=0pt,top=0pt,bottom=0pt,nobeforeafter]

Q: What is the use of percent signs (%) at the end of lines?

I see that the code in many packages and examples contains percent signs % at the end of (many) lines. What are they used for? Do they affect the parsing of those lines?

Christian Hupfer

@1010011010: This changes according to the margin

@DavidCarlisle: I knew that would come ;-)

1010011010

10:50 AM

\raisebox{3.5ex}{%
\fboxsep=10pt%
\colorbox{palette2}{%
\parbox{\dimexpr\textwidth-2\fboxsep}{%
\includegraphics[height=8ex]{logo_uva.png}\hfill\includegraphics[height=8ex]{logo_iis2.png}%
}
}
}

Where would that come from ?

You have \colorbox{}{\oarbox{}{...} } so the colorbox needs to be one word space wider than the parbox which is one word space too wide.

@1010011010 so you should have \colorbox{}{\oarbox{}{...}} without the space

1010011010

@DavidCarlisle I've never had issues with closing braces that needed %'s..... I admit I'm confused now.

David Carlisle

@1010011010 yes you have:-) you just didn't notice before:-: If your tex source was:

\parbox{3cm}{one
two
three
}

You would expect word spaces between one and two and two and three. that only happens because end of line is treated as a space.

@1010011010 compare

\fbox{one}

\fbox{
one
}

@DavidCarlisle I understand where it comes from, I just don't understand why it wasn't an issue previously.

David Carlisle

@1010011010 It was an issue, you didn't notice:-)

Q: Changing Page Margins with Geometry causes empty pages

I tried to change the borders of the pages in the entire document. Using geometry, I got 9 pages of blank output. Using this for the entire document, I got 98 blank pages. What am I doing wrong? Are there more reliable methods than geometry? Thanks in advance! % !TeX encoding = UTF-8 % !TeX sp...

@ChristianHupfer Awesome.

Christian Hupfer

@1010011010: What?

1010011010

@ChristianHupfer Your link is now awesome.

Christian Hupfer

@1010011010: About the units? ;-)

egreg

@ChristianHupfer Or the OP has really big paper.

Christian Hupfer

@egreg: Printing a journal on A0 - paper, why not... the printer itself could be a little bit expensive

egreg

11:31 AM

@ChristianHupfer Maybe A{–1}

Christian Hupfer

@egreg: Now you exaggerate.... A0 was realistic :-P

egreg

@ChristianHupfer This reminds me of a very large poster I saw in Romania in 1989, something like 30 meters wide and 15 meters high, featuring the Conducător and his wife smiling to the populace.

@egreg: I assume, it was destroyed not long after....

egreg

@ChristianHupfer I guess so, too.

Christian Hupfer

@egreg: Did you attend a conference there at that time?

egreg

@ChristianHupfer Yes, July 1989. We went there by car and it was a very instructive travel. At the border check a woman officer asked us: “Have you got arms, drugs, religious items, pornographic items?” (in this order).

Christian Hupfer

@egreg: I could make a cynical comment on that ... but I prefer to keep silent ...

@DavidCarlisle You sir are a Paint legend. :)

@PauloCereda: Even more... @DavidCarlisle sketched that with his bare hands, even out-standing his famous house sketch he's done recently ;-)

I cannot do more than write minimal working example <- Link. Should i hack the system so that links to MWEs start dancing on the screen?

yo'

@ChristianHupfer not at all. Most books are printed on sizes A1 and A0, and then folded and cut.

Christian Hupfer

@yo': Yes, but most of us do not own an A0/A1 printer at home...

yo'

@ChristianHupfer no, that's right :)

Christian Hupfer

@Johannes_B: You should update that link ;-)

@christian I won't. It is so nicely available by just typing ctrl+t to open a new tab, type mi arrow down to times ctrl + c to copy ctrl+w to close the tab and ctrl +v to insert it. And i bet anybody how is intelligent enough to use LaTeX and is able to read can follow that one and only thing that is on that site. If someone is not able to do that, Darwin has won. Period.

@ChristianHupfer golatex.de/viewtopic,p,68260.html#68260 If that guy would have looked at the stuff i wrote there, he would have already seen the link that addresses his question.

@ChristianHupfer I have the feeling that 90 percent of the topics i answer at LC never get any further reaction.

@Johannes_B: The smart way: Calm down and take a deep breath ... familiar to you? ;-)

Johannes_B

@ChristianHupfer I should listen to this :-)

Christian Hupfer

@Johannes_B: So, Ich muß meine bessere Hälfte vom Bahnhof in FR abholen... Bis später vielleicht

Johannes_B

@ChristianHupfer See you und liebe Grüße :-)

Christian Hupfer

@Johannes_B: Danke
