@cfr So sad, I converted the Wales dragon to TikZ/pgf but the code is too long to be uploaded. :-(

2:35 AM

It just occurred to me with all this flag business that in addition to Italy, the Netherlands isn't in the World Cup. Isn't this also unusual?

@AlanMunn Yes, it is. But Iceland was in!!! (Iceland has less population than Bologna -:)

Q: Let's hold language in comments to the same standard as posts

Through his never-ending sense of wonder and curiosity, my colleague Jon Ericson recently posted some findings on his exploration into the possibility of ...hastily written... questions essentially becoming an (inevitable or not) self-fulfilling prophecy. While we're getting a little out in the...

discussion featured comments comment-flags

I wonder what other sites allow!

8:12 AM

@marmot I bet you can use tex macros to compress it:-)

8:48 AM

@marmot May I ask how you converted it? svg2tikz with inkscape?

@marmot More bytes than Welsh people?

@egreg you should count sheep not people

@egreg re your "rant" what mainly is wrong is isomath package name (and Will's iso style option) implying that this is some sort of global style guide from ISO. ISO 80000-2 is Quantities and units — Part 2: Mathematical signs and symbols to be used in the natural sciences and technology so it's only supposed to be used for specific quantity references in specific fields.

@DavidCarlisle quack

Apr 15 at 9:38, by David Carlisle

@PauloCereda dinner!

@DavidCarlisle oh no

9:57 AM

@DavidCarlisle Sounds like an entirely sensible ISO to me ;)

10:12 AM

@JosephWright @DavidCarlisle is exit status 256 the same or something different to exit status 0 in a l3build check with luatex?? (I'm comparing some tests of the unicode-math testsuite with my results).

@UlrikeFischer Exit status is a bit odd: various TeX processes return strange values

11:03 AM

@JosephWright you tell me. :)

@PauloCereda Exit status is a bit odd: various TeX processes return strange values

@DavidCarlisle ooh exit statuses

11:31 AM

@JosephWright Yes, a short search showed that there is quite a variety of exit codes ;-). Imho you could put a warning symbol "tricky" in the docu before the section about testfiles;-). But my main question is if "256" on (probably) Will machine means the same as "0" on my windows? I guess yes.

@UlrikeFischer Almost certainly :)

11:48 AM

@UlrikeFischer I don't think anything is supposed to return 256 tldp.org/LDP/abs/html/exitcodes.html

Hi, sorry for the interruption. Could anyone please tell me if there's a LaTeX command that has a | in its name? Background: I need to insert programmatically a LaTeX command, and then position the caret at a particular position. For example, if the user inserts \mathrm{|}, then the caret would be positioned right between the braces. I was worried if the | would have a naming conflict with an existing command

(just in case the user wished to position their caret in the middle of the latex command, like so \mat|hrm{})

(i know that \mat|hrm{} would be a rarity, but I am trying to make my code user-proof :) )

@DavidCarlisle perhaps in Australia it is different ;-).

12:07 PM

@GaurangTandon you can only have letters in multi-character commands and (almost always) | is not a letter, so the command \| exists but you can not have \math|rm

@DavidCarlisle thanks for the confirmation :)

\catcode`|=11 \newcommand\math|rm{oops} ... \math|rm if you want to see it fail @GaurangTandon

@DavidCarlisle i'm afraid I don't have a LaTeX parser yet, I just rely on StackExchange's Mathjax. Sorry! :O

@GaurangTandon mathjax doesn't allow such games:-)

:P

1:03 PM

@DavidCarlisle What about |gdef|@xverbatim#1\end{verbatim}[#1|end[verbatim]] ? :)

1:14 PM

Hello!! I want to write a pdf in the form https://imgur.com/a/md5Ajk4 i.e. that on the top left there is the name and under that the name of the prof, in the middle the name of the subject and under that "Handout" and on the right SS18 and under that the date.

Do I use for that \documentclass{article} or something else?

Hello @DavidCarlisle !! Do you have an idea?

@MaryStar you could use almost any class for that, if using article, use fancyhdr package which allows you to specify left center and right part of the page head

@GaurangTandon mathjax doesn't allow such games:-)

1:32 PM

@DavidCarlisle You're no fun.

@DavidCarlisle Thank you!!

2:15 PM

really, @David ? tex.stackexchange.com/a/438228/100482

this has been flagged as low qual, btw

Why does the command "\newcommand{\a}{\mathcal{A}}" not work yet "\newcommand{\h}{\mathcal{H}}" does?

@user193319 Because \a is already taken

Oh, I see. Thanks!

What does it do? I just tried entering it in my document and it doesn't seem to do anything.

@user193319 It's used in tabbing for accents

2:52 PM

Badger England Football

ENGLAND ENGLAND

@naphaneal I figured @daleif wouldn't require any more information.

@DavidCarlisle If Brazil loses today, your money is lost...

@PauloCereda BAGDERS!

@JosephWright ooh it is a snake

@DavidCarlisle yeah...I know, that you know, that he knows, and we know that. but others might not know, so they need to know. you know? :D I skipped the question anyway.

2:55 PM

Das ist ein goal!

@naphaneal that was also all the information I had. I don't know marginnote that well, I just guessed resetting everypar would do something, it produced the requested answer so I posted.

@PauloCereda I'll just take it from your credit card

@DavidCarlisle oh no

@PauloCereda depending on the context, "goal" translates to "Tor", "Ziel" or "Zielstellung". what do you wish to express with that statement?

@naphaneal wow, I just wanna say goal as in football. :)

then "goal" translates to "Tor" in your case

@PauloCereda mushroom, mushroom

3:00 PM

@naphaneal ooh

@PauloCereda don't believe @naphaneal. Clearly the first two are far too short to be real German words.

@DavidCarlisle ooh good point

@DavidCarlisle right...it should be "Torhüterversagenskonsequenz"

@naphaneal much better!

@DavidCarlisle you only need to use them often enough "TorTorTor" youtube.com/watch?v=bxV5buoANQA

3:06 PM

@UlrikeFischer but TorTorTor = 3 goals, right? :)

@PauloCereda how many goals are chat.stackexchange.com/transcript/message/45306196#45306196?

@UlrikeFischer ooh

@DavidCarlisle I tried that of course.

@samcarter Not quite. I tried to be clever and convert it to pstricks and then to pgf. Turns out that this was not clever. :-(

@marmot see the comments under here, i had to get it down from 40k to under 30k :-) tex.stackexchange.com/a/149616/1090

Yes, that's clever. My attempt was much more mundane:
\let\plt=\pgfpathlineto
\let\pmt=\pgfpathmoveto
\let\pct=\pgfpathcurveto
\let\ppt=\pgfpoint
etc.

3:14 PM

@marmot tikz of course is (by design) a compact syntax for pgf paths....

@marmot Ouch. This code should throw an error Working with ppt in LaTeX is discouraged ;)

@DavidCarlisle Well, I guess there must be a way to make this much more compact by just drawing through some relevant points. Of course, I have no idea to implement this. Maybe I need to learn machine learning to do that ;-)

@TeXnician I just made ppt so much more meaningful ;-)

@marmot you should post the file somewhere then have a competition who can shrink it enough to post here without changing the output:-)

@DavidCarlisle Nice idea but I do not think I need to put the file. One could just ask to draw the Wales dragon in a as short as possible short macro. The svg is known. (I am however not convinced that the picture mode will win this competition. ;-)

@marmot picture mode is like Serena Williams, deserves its place for historical achievements if not current form.

3:35 PM

@DavidCarlisle who?

@DavidCarlisle tree rooted on a farewell ...

@DavidCarlisle Well, seems consistent with my suspicion that it/she may not win the tournament. ;-)

Hi everyone

'ello

@opisthofulax Hello

3:40 PM

I started writing a new book about optics

We ducks like to welcome people. :)

and I would like

to know

which is the best to typset margin notes

because I'm facing so much troubles

with margins on the wrong side, not breaking page and so on

some advice on the easiest and most functioning way

:)

@PauloCereda nice

I mean the ducks that like to welcome people

TOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOR

2

@naphaneal ^^ did I get that right? :)

3:56 PM

@PauloCereda yup

@opisthofulax I don't have much experience in using marginal notes, but perhaps it might be interesting to learn more about the class you are using. Some of them provide better space, others don't. And also, perhaps considering another way of representing notes.

TOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOR

Germany is out of WC

@PauloCereda oh, well, they should have installed the Turkish ones.

@yo' :)

4:19 PM

@marmot Oh, then inkscape foo won't help to shorten the code.

@samcarter I know and actually that's a repeating theme on our site. In principle it should be possible to train a machine to detect all the edges and draw them with simple commands, but I don't see myself writing such a code. (Inkscape is actually particularly "good" at cutting the paths down to very short pieces.)

@PauloCereda I think you were saying it wrong:

해버지 60m 드리블 후 완벽한 크로스 어시스트 ● 대한민국 vs 호주 ● 하이라이트

@AlanMunn gor? :)

@AlanMunn it looks like a caipira variation!

@marmot I have good experience with the "simplify path" option in inkscape.

@PauloCereda mogpyo

4:34 PM

@AlanMunn ooh

@marmot The problems is: define "simple commands". For a machine it is certainly much simpler to approximate a shape with many straight lines.

@samcarter I didn't even know about it. (I am actually particularly stupid with regards to inkscape, I never managed to install the convert-to-TikZ plugin and so on.)

@samcarter Yes, sure. But I guess one day someone may have written a code in which the machine recognizes long paths and draws them with some plot[smooth] or another command with very little support points.

GOOOOOOOOOOOOAAAAAAAAAAAAAAAAAAAAAAAAAAAAL

@PauloCereda GOOOOOOOOOOOOOOOOOOOOOOOOOL?

@marmot ^^^^

@DavidCarlisle You win! (But why is the dragon heading to the right? On the official site it is heading to the left... )

Ah, got it. you put a - in \begin{tikzpicture}[scale=-.4].

@marmot details it was upsidedown so I added scale -4 If I knew any tikz I could scale just in y-direction or rotate or something:-)

@marmot the svg I used ^^

@DavidCarlisle [yscale=-0.4,xscale=0.4]

@marmot details.... (need to just fill the green and drop the drawn outline as well

@DavidCarlisle ???

4:57 PM

@marmot the green rectangle in my version seems to have a black border

@DavidCarlisle \fill[dgreen] instead of \draw[fill=dgreen]

@marmot I do have a gold tikz-pgf badge you know

@marmot obviously anyone with a gold tikz-pgf badge would know that:-)

@DavidCarlisle You should post it here ... and even I have such a badge, doesn't mean anything ;-)

@marmot wales were not in last 32 were they?

@UlrikeFischer Good. :)

5:00 PM

@DavidCarlisle They were not admitted because their flag is too complicated, I guess. ;-)

@DavidCarlisle This didn't stop the GB flag from showing up. :)

Harald Hanche-Olsen

5:56 PM

@AlanMunn You mean this one?

(Sorry, I messed up my first attempt and now I can't delete it.)

Maybe Germany lost on purpose so they can prepare their TeX talks and attend TUG 2018.

@HaraldHanche-Olsen Yes. That's the one.

@HaraldHanche-Olsen GB does not compete in football.

@HaraldHanche-Olsen Of course one can say the same for Italy and Germany... :)

Harald Hanche-Olsen

6:13 PM

@AlanMunn Well, I thought since the Kingdom of Great Britain only existed until 1801, it would be odd indeed to see them fielding a football team. But apparently the UK doesn't either; but England does.

@HaraldHanche-Olsen The UK is a strange place. UK = 3 nations (England, Scotland, and Wales) and Northern Ireland. GB is technically the first three. Each of the 3 compete internationally separately in many sports except the Olympics. N. Ireland is complicated. Since anyone born in N. Ireland has both UK and Eire citizenship they can compete either on the UK team or the Irish team.

@AlanMunn allow me, kind sir

The Difference between the United Kingdom, Great Britain and England Explained

@PauloCereda Yes this is a nice summary.

@AlanMunn :)

@PauloCereda Although he overstates some things. I think most English, Welsh, and Scottish people tend to describe themselves as British, and I don't think it's true that "they don't like each other".

6:26 PM

@AlanMunn I've no idea!

@AlanMunn A town near were I was born is named Bovisio-Masciago because it came out from the join of two little towns. The inhabitants of Bovisio don't like the ones of Masciago and vice-versa. So, it is not strange for me that British don't like each other...

@PauloCereda oddly Brazil didn't appear in the Venn diagrams at all. Perhaps you don't exist.

@DavidCarlisle We are not a colony. :)

@CarLaTeX Except they don't (generally).

@PauloCereda Try telling that to the Portuguese. :)

@AlanMunn Well, we had another empire. :)

GOOOOOOOOOOOOOOOOOOOOOOOL

6:37 PM

@AlanMunn Aren't you Canadian? How do you know that? :)

@CarLaTeX I'm British as well. I grew up in Canada and only became a citizen there before I moved to the US.

@AlanMunn NOW I understand why you like pineapple pizza. ;-)

@AlanMunn Oooh

@marmot <3

@marmot and Nutella pizza is good. :)

@marmot :D yeah, it's clearly causal. But legend has it that Canada had pineapple pizza first.

6:41 PM

@AlanMunn Yes, but not invented by a Canadian, right?

@marmot Well by a Greek-Canadian.

@AlanMunn and Brazilian by attribution. :)

@AlanMunn Yes, and there is some millennium-old tension between the Greek and the Romans... ;-)

Obviously, not an Italian!

@marmot What have the Romans ever done for us?

6:44 PM

@AlanMunn This invention may not have helped to decrease the tension...

@PauloCereda why just have one good thing if you can have two?

yelp.com/biz_photos/…

@AlanMunn \renewcommand{\theenumi}{\roman{enumi}}

@DavidCarlisle Holy cow

@DavidCarlisle O-H M-Y-!

6:47 PM

@AlanMunn See?

@PauloCereda you can always rely on google to find whatever you need:-)

@DavidCarlisle :)

@AlanMunn Why do Anglo-Saxon write Roman numbers in lower case?

@CarLaTeX WHAT HAVE THE LOWERCASE ROMANS EVER DONE FOR US

@CarLaTeX BECAUSE IT IS RUDE TO SHOUT

6:50 PM

@CarLaTeX Because upper case is close to underlining in typographical ugliness.

@CarLaTeX because they drive on the wrong (as opposed to right) side of the street?

@CarLaTeX because the shift key thingy in their typewriters broke and they had no one to fix... :)

I like my explanation better

@PauloCereda you are thinking of @barbarabeeton

@DavidCarlisle ooh

@CarLaTeX Because we've moved beyond carving in stone.

6:52 PM

@marmot They don't make a right!

@AlanMunn ooh carving a cake

@PauloCereda You don't carve cakes. You carve ducks though.

@AlanMunn OH NO

user image

@AlanMunn OI

By the way...

@JosephWright: HAPPY BELATED BIRTHDAY (25)

6:57 PM

@PauloCereda Such a young guy.

@PauloCereda isn't that early rather than late (according to skype at least:-)

@AlanMunn :)

@DavidCarlisle really?!

7:14 PM

@DavidCarlisle Well, depends on which birthday you are talking about, right? ;-)

@marmot the queen can have two birthdays a year so why not Joseph?

@DavidCarlisle I agree. But I am not sure if he would like that because it would make im age faster ;-)

@marmot for a chemist maybe it would, mathematicians are Ok with having twice as many half year birthdays resulting in the same number of years.

@marmot I suppose an age of two or three is already old for you

@DavidCarlisle Not really, just need to stay away from the eagles ;-)

@PauloCereda GOOOOOOOOOOOOOOAAAAAAAAAAAAALLLLLL

7:27 PM

@CarLaTeX I gather my money is looking safe?

@DavidCarlisle It seems so :)

@DavidCarlisle Marmots can get quite old ;-)

1 hour later…

8:58 PM

@PauloCereda For tomorrow? ;)
