@PauloCereda Glad you got it at last!

I've confirmed IEEEtran was the right package with 'sudo tlmgr search --global --file IEEEtrantools.sty'

any ideas as to why this isn't working out?

@skillmon codegolf.stackexchange.com/a/159718 was a real success! Thank you for your input!

@AlexG Ducks are invading also other SE sites, yay!

bon giorno, @CarLa

was that correctly spelled?

@AlexG Buongiorno anche a te, qua qua qua!

Gracie! I am not good at italian.

@AlexG Almost: bon is buon, also buon giorno is correct

@AlexG I'm not good in English, so don't worry! :):):)

@AlexG Gracie is grazie and we reply prego! = you're welcome!

@AlexG You're welcome :) Though I'm a bit disappointed that you haven't beaten that C64 crap :)

@CarLaTeX We're working on it. Maybe we should write a Python Module which is for ducks, or something like that :)

@Skillmon LOL

@ashgetstazered so where is it installed?

@CarLaTeX or pizza recipes

@DavidCarlisle :P I'm not a good cook, indeed, I think @UlrikeFischer it's much better than me!

@CarLaTeX It's easier to get the necessary ham pineapple slices in Germany, so she has an advantage

@cfr <3

@DavidCarlisle Das Ananas

@PauloCereda Die Ananas ;-)

@UlrikeFischer ooh :)

@DavidCarlisle She is a good cook because there is no pineapple in her pizza!

@CarLaTeX but there is pineapple in one of my risottos.

@UlrikeFischer Oh, there are people who make risotto with strawberries, maybe also pineapple is good, LOL

Nutella pizza is good.

@PauloCereda Nutella pizza is a focaccia!

@PauloCereda :P

@CarLaTeX btw did you see the name of wine we drank with the pizza?

@PauloCereda ignore silly conventions that assign arbitrary gender to inanimate objects

@DavidCarlisle ooh

@DavidCarlisle lady sunshine and mister moon ...

Good morning to everybody

@UlrikeFischer, @egreg, @CarLaTeX, @ChristianHupfer, @DavidCarlisle Hallo.

@egreg Excuse me. I have not seen the duplicate of a old version.

@UlrikeFischer I didn't notice it, I'll search for your post

@egreg Now I'm removing my answer.

@Sebastiano It's a 4 year old answer, but there was a comment just a few days ago, so I could find it easily.

@egreg the new question has a "just use the unicode symbol" answer, which should probbaly be merged with the old question (unless you want to update your answer there with a unicode-math alternative?)

@Sebastiano I deleted mine too. Let's call it my own punishment for breaking my own rules: Never answer a question when there is a duplicate you already upvoted in the past :-)

@egreg I'll leave a comment under the answer suggesting he copy it

@DavidCarlisle :)

@UlrikeFischer hahaha very appropriate for pizza!

@Sebastiano Ciao! How are you?

I figure my question probably does not warrant a question, so I'll ask it here

I like to use \titleformat{\subsection}[runin] which will create a section with text of the body of the paragraph right next to it. How can I right align such a paragraph?

oh darn wait a sec

I've already tried this, but there's an extra linebreak right before the start of the paragraph this way

@skillmon we are catching up (codegolf), only 4 pts difference!

What I also would like is if the paragraph text would be constrained to not fill the full page, but sort start right after the section headers.

@AlexG: another upvote in your duck answer. :)

@paulo Bom dia! Jà notei, senhor pato paulista. Obrigado!

@AlexG ooh :)

@rien333 it would be much easier to understand if you asked as a question on the main site with a complete example \documentclass...\end{document} \section{..} does not make a scope for the text so if you want the text right aligned perhaps you want \begin{flushright}\section{zz}....\end{flushright} but hard to guess

@AlexG You can save one token by using \tikz\duck[body=\csname\the\b\endcsname];

@Da

@DavidCarlisle Yes, perhaps. I just suck at latex though and I feel like my question isn't general enough. (+ it's a small and easy thing so that's why I asked here) I think I just have no feel for the language yet

@UlrikeFischer Thank you! Just edited it.

@AlexG But you inserted a space after the ;.

@ulrike yes for avoiding the line to spill over the right page margin

A discussion which started elsewhere but I guess that people here might know. (Of course, it would be possible to ask on the main site - but I am not sure to which extent it would be good/useful question.)

It is related to bra-ket notation. Is $\left<0\middle|1\right>$ and $\left\langle0\middle|1\right\rangle$ rendered the same in LaTeX?

@DavidCarlisle let's talk about cricket

@DavidCarlisle But is it OK to chat in the questions? ;)

@PauloCereda they rub their wings together and make a noise

@mickep ooh a conundrum

@DavidCarlisle so football it is

@mickep no, if you post more than a dozen comments you get an automated telling off from the system and it tries to move you to a new chat room:-)

@PauloCereda did you watch superbowl?

@DavidCarlisle only a super bowl of Pringles

@PauloCereda don't feed crisps to ducks

@DavidCarlisle oh

If we end too many sentences in the chat, then maybe the system should move us to the main site?

(Sorry, I'm a bit bored. Correcting exams)

@mickep ooh I like this idea

@PauloCereda I wonder what should happen if one says "ooh" too many times (is that possible?)

@mickep ooh

@mickep 4650 times for example?

chat.stackexchange.com/search?q=ooh&user=6485&room=41

@DavidCarlisle Hahaha! I love those kinde of statistics!

@MartinSleziak yes < has a delcode that uses the same slot as the \delimiter definition of langle (in latex and plain tex)

Thanks, David Carlisle!

@DavidCarlisle ooh

@DavidCarlisle One gets \penalty10000 after saying only “ooh” on a reply 10000 times.

@egreg Will @PauloCereda reach 10000 “ooh”s before you reach 654321 rep?

@HaraldHanche-Olsen Asking the real questions.

@PauloCereda now you invalidated @DavidCarlisle's counts. Congratulations!

@yo' <3

@HaraldHanche-Olsen ooh

@yo' I tried to use an enumerate environment in a beamer document. It took me ages to find out that's not legal. May be unrelated, but it reminded me of that.

@thymaro Huh? enumerate works fine in beamer.

@TorbjørnT. using xelatex and metropolis and without enumitem loaded, it didn't for me. I had capacity overload 5000. Then, I turned all the enumerates into itemizes and it compiled just fine. What did I miss?

TeX capacity exceeded, sorry [input stack size=5000]. \end{frame}

@thymaro beamer and enumitem don't go well together I think.

@thymaro With enumitem I get the same error, without it works fine.

@TorbjørnT. silly me! I didn't check whether the template I stole had enumitem in there. It did. I deactivated it and now I have bullet points in my itemize environments and numbers in enumerations.

oh well, the presentation was yesterday evening, so that's that...

@TorbjørnT. my experience precisely. Anyways, thanks for the hint!

@TorbjørnT. @JosephWright is that a known issue?

@DavidCarlisle Not actually sure, I think I've read it somewhere on the site. Don't have any specific examples though.

@DavidCarlisle Yes. Because beamer messes a lot with lists to get overlays, it simply doesn't work with enumitem.

@AlanMunn you should ask Joseph to rewrite enumitem in a beamer compatible way

@DavidCarlisle l3enumitem of course.

@JosephWright please rewrite l3enumitem in a beamer compatible way. thanks.

let's see

@DavidCarlisle He can do this while he finishes l3beamer.

is there a roadmap for l3?

@thymaro yes: don't panic. :)

@JosephWright 's online dating profile: "I write TeX software. In my spare time, I'm a lecturer in Chemistry."

@thymaro there is this, from 1999 but still more or less describes the same road latex-project.org/help/documentation/ltx3info.pdf

@DavidCarlisle Paved with good intentions.

@thymaro You do realize we're joking, right?

@DavidCarlisle haha first time I saw this document (about 2 years ago), I thought I had somehow landed on a waybackmachine's version of the file. Then I realized I hadn't.

@AlanMunn you mean because of this? chat.stackexchange.com/transcript/message/43538209#43538209

@AlanMunn It's impossible to tell the jokes and the serious stuff apart in this chat. Except when it's about pizzas with pineapple: That's deadly serious.

I do indeed. People often have a hard time discerning whether I'm joking or earnest. Not only on the internet...

@thymaro Yes.

@HaraldHanche-Olsen True. We won't rest until the Italians have seen the pineapple pizza light.

@HaraldHanche-Olsen I actually had to laugh at this. Whether it's serious or not is not the point, imho. If it's funny, it's funny and can still be serious matter. Sometimes, it's not so important, whether something is meant in a serious way or not. If you can chat about it in a joking way, good ideas my emerge from such a conversation more quickly than if people were about a specific theme and trying to "produce" something or finding the solution to a problem while staying dead serious.

The mind often works more creatively when it's allowed to make jokes about serious things.

I am a very serious duck

@PauloCereda Seriously?

I happen to unsettle people...

@AlanMunn hmm, seems pretty serious to me

@PauloCereda Nobody doubts that! :)

@AlanMunn I am super cereal

@PauloCereda You're not helping your case. :)

@AlanMunn I blame Al Gore. :)

@CarLaTeX Of course one of the curious things about the semantics of adjectives is that they are always relative to the noun they modify. So a "big ant" isn't very big even though a "small elephant" is. So just how serious is a serious duck?

@AlanMunn Oooh interesting question!

@CarLaTeX @PauloCereda Wait, are you telling me that your profile pictures are not real photographs of you?

@marmot I am a duck. :)

@PauloCereda Yes, and I am a marmot.

@marmot <3

@marmot Of course they are real photos, I also have a pizza, how could you doubt it?

On the Internet, nobody knows you're not a duck.

@HaraldHanche-Olsen quack

@PauloCereda "A serious duck is serious in an aristotelian sense being an emanation of the very essence of seriousness" (forwarded from someone sitting currently in a boring meeting)

@UlrikeFischer ooh

@PauloCereda Which remembers me that I forgot to starred David's statistic.

@UlrikeFischer :)

@ChristianHupfer Your self restraint is admirable!

@AlanMunn I had something about 25000 rep once there, but due to wrong click it was 'lost' ...

@ChristianHupfer :)

nearly ... I'm simply not being attentive enough.

@UlrikeFischer We can remove 3 upvotes :-P

@ChristianHupfer I don't think this will be sufficient, I guess.

@marmot 3 upvotes for questions will mean 30 rep ... if the image shows the current rep, it should be 163,361 after removal of 3 votes...

@ChristianHupfer What I mean is that she will pick up reputation while you are doing that. And I am not sure if the system works that way, I got the impression that a downvote does not reverse the reputation gain from an upvote when done after some period, but I may be wrong.

@UlrikeFischer -- but you can rotate this 180 degrees, and it matches itself, modulo a couple of serifs.

@marmot You can undo (up)votes, if an answer has been recently edited.

@barbarabeeton I thought that a rotated 3 would more look like a \varepsilon.

@TorbjørnT. Thanks a lot! I'm not very good at downvoting ;-)

@marmot -- oops! you're correct. okay. let's look at this another way -- flip the last three digits upside down. and you've got a mirror image (modulo a couple of serifs). (did i get that right?)

@barbarabeeton ... and if you rotate it by 360 degrees, you'll get the same image ;-)

@barbarabeeton from every point of view it is a "nearly" hit ;-)

@marmot -- well, i can't argue with that. (it's supposed to start snowing here ... again ... and i'm just waiting for that to happen so i can go home.)

@barbarabeeton We had this before. There are good reasons to hibernate at this time of the year. ;-)

@marmot I am not talking of downvotes of course -- unupvoting

@ChristianHupfer Even with this I'm not too familiar. (I also find it hard to imagine a case where it makes sense. Of course, in principle may replace a stellar answer by some crap, but how often does that happen?)

@marmot Say you have downvoted a crappy answer. The user then edits the answer, so that it is no longer crappy enough to deserve that downvote. Then you can undo the downvote.

@TorbjørnT. Sure. But the discussion was about how to reduce @UlrikeFischer's score.

@marmot I was talking of a temporary reduction of course

@marmot Sorry, was thinking about undoing votes in general.

@ChristianHupfer She could do that herself: just delete an unaccepted answer with score 3 (or with score 1 or any other partition of 3). She can still undelete later.

@marmot That would be 'personal' cheating ;-)

@egreg I have not seen :-)

@TorbjørnT. I see. (I've not yet been in this situation simply because I am very sparse with downvotes. Most of the posts show at least some effort, so I don't want to downvote, and those who want to annoy others do not deserve my attention.)

@ChristianHupfer I can see the tabloid headlines now. TeX.se scandal! Users rigging votes to get palindromic reputation counts.

@ChristianHupfer As opposed to delegated cheating?

@marmot, and to everybody hi

@campa It's true.

@Sebastiano Ciao. Come stai?

@marmot Sincerely the same of yesterday :-) There is many works for my job at my school

@Sebastiano Yes. Schools and universities would be much more relaxing without all these students ;-)

@marmot @CarLaTeX I'm very tired. I would have an holiday of 365 days

@egreg Hi prof

@marmot Most users here fairly sparse with downvotes I think (me included). Another case where unvoting could be useful is if one votes by accident, either up or down, when the post deserved neither.

@marmot No, the students are fine, it's the administrators we need a rest from.

@marmot my pupils of the my school are special but they not studies :-(

@TorbjørnT. Very common when using your phone. :)

@marmot I also do university research and yesterday, with all sincerity. I performed a specialist visit. The doctor told me to stop studying :-)

@marmot Exactly...

Holy week approaches!

@AlanMunn Overall I agree but I am currently grading the finals. These were not written by administration. (And I have refrained from logging into TeX.SE on my cell phone, I guess when one is doing that it might be a sign that something is not as it should be ;-)

however, now I greet everyone and thank you always for your presence.

@PauloCereda ... because your thesis comes to an end? ;-)

@ChristianHupfer oh no

bye to everybody

@Sebastiano me too!

@marmot Well it's true that grading is the bane of our existence. You must be on the quarter system then? Otherwise this is a very odd time of year to be grading finals.

@PauloCereda A week full of holes?

@HaraldHanche-Olsen ooh

@PauloCereda Another one!

@HaraldHanche-Olsen In Blackburn, Lancashire?

@AlanMunn I am. And it is a real scandal that our administration does not allow for a hibernation leave. ;-) (The good new is that the class only has 6 students, and I arrived at the last one...)

@marmot You're not allowed to pack your teaching into two of the three quarters?

@AlanMunn Sure, in principle I am, but in practice not because I teach a 3-quarter series. But it's a fun course, no complaints. (2 Students even use LaTeX to type the answers of the homework problems ;-)

Is it just me, or are different conversations being mixed together here? I am getting confused.

@AlanMunn You lost me on this one, for sure.

@HaraldHanche-Olsen No way! We marmots left the UK long before Brexit. It's a dangerous place in which people destroy pizza by putting pineapples on top.

@marmot Or destroy pineapples by putting pizzas underneath! The depravity!

@marmot Like this?

@marmot That would be “so long and thanks for all the fish and chips”

@egreg One of the favourite songs of my oldest daughter!

@skillmon @samcarter : Oh my, ↗tikzducks rule!

@AlexG The most upvoted!

@egreg Grazie, but marmots do not eat fish. But yes, this is a nice way of saying good by at the end of a sushi dinner.

@marmot But pineapple pizza is available on the continent (= the real Europe ;-)) as well :-( It's not restricted to the UK

@AlanMunn That's mean ;-)

Oh wait...

@PauloCereda Spot the looney....

Ok, so the statement I wished I knew to prove works for the first 9906946048 cases. I hope it's really true.

@AlexG yep, just saw it and wanted to post here :)

How can I check whether a token is alphabetic ( so in [A-Za-z]) without any packages (including l3)?

@yo' Have a look at Skewes's number and despair.

@Skillmon catcode=letter?

@UlrikeFischer fails if the input is a control sequence.

@Skillmon Since when where [A-Za-z] the only alphabetic tokens?

@HaraldHanche-Olsen which do I forget (I'm not speaking of directly of catcodes here, though they might help)?

@HaraldHanche-Olsen And don't say ampersand. It was part of the english alphabet, but I don't consider it to be alphabetic :)

@Skillmon In Norwegian: ÆØÅæøå; the entire Greek alphabet, …

@Skillmon Indeed, the very word “alphabet” come from αβ.

@HaraldHanche-Olsen ok, that's valid. The let me formulate my question in the following way: How do I check if a token is in [A-Za-z] :)

@HaraldHanche-Olsen yes, I know that. That's why I specified [A-Za-z]. But I admit it was not well formulated.

@Skillmon You can expand the control sequence before checking the \catcode...

@Skillmon I can think of no other way than performing 52 \ifx tests, myself.

@PhelypeOleinik nope. Fails e.g. for \relax, and every other non-expandable control sequence.

@HaraldHanche-Olsen I hoped there was something better :(

@Skillmon Ooh, indeed. I thought that you was going to test characters only...

@HaraldHanche-Olsen Or \if a\detokenize{#1}\relax (which sadly isn't better)

@Skillmon You can at least check for what TeX considers a letter by exploiting the expansion of \meaning <token>. If the expansion starts with “the letter”, then TeX does indeed consider it a letter.

@Skillmon if you know it is a character token, then \uppercase{\ifnum`#1>64 \ifnum`#1<91 yes \else no \fi\else no\fi}

@DavidCarlisle it could be anything valid in math mode :(

@HaraldHanche-Olsen Well, here we know that there is a bound K such that V(n) for all n if and only if V(n) for all n<K. And we believe this bound is reasonable. The problem is that it's unknown :)

@Skillmon although testing catcode11 is probably better (but you explicitly said not that??)

@Skillmon ?

DUCKS

@PauloCereda ooh

@DavidCarlisle \newcommand\getcatcode[1]{\the\catcode`#1}\getcatcode{\sigma}

@Skillmon oh well you can test the token is a character token first

@DavidCarlisle how is that done? With \meaning and parsing its output?

@DavidCarlisle bu expanding its \meaning?

@Skillmon that would need to be `#1 anyway or it will fail for characters as well

@Skillmon \ifcat\noexpand#1\relax

@DavidCarlisle the tick was there, just forgot to escape it for the syntax highlighting

@HaraldHanche-Olsen all non-character tokens are equal to \ifcat

@HaraldHanche-Olsen ooh quoting

@Skillmon so basically what is wrong with the test \ifcat\noexpand#1 a it's a letter\else it isn't\fi

@DavidCarlisle Oh, right. Not thinking straight today. (I crashed my car on Monday, and still haven't recovered mentally.)

@HaraldHanche-Olsen oops hope everything is Ok (with humans, not the car)

@HaraldHanche-Olsen sorry to hear.

@DavidCarlisle Humans just fine, thanks. Car not so good, but insured.

@HaraldHanche-Olsen oh no, sorry to hear

Actually, it happened because of an extremely icy road. After the accident, I got out of the car and found it nearly impossible to stand up. So I have some blue marks after the resulting fall. Great comedy, but I wasn't in the mood.

@DavidCarlisle \def\ifletter#1{\ifcat\noexpand#1 a it is\else it isn't\fi}\ifletter{a} returns "it isn't"

I'm away for a while. My daughter vomited in her bed :(

@Skillmon sorry spurious space should be #1a not #1 a Hope your daughter isn't too unwell

@DavidCarlisle Well, if after \let\a=a you consider \a a character token.

@HaraldHanche-Olsen if DEK does, I do too:-)

@HaraldHanche-Olsen \bm ends up dissecting \meaning for most of its tests I have to admit.

@DavidCarlisle she's sleeping again. Seems like the dinner wasn't to her stomach's liking. Now it works perfect, it seems (why didn't I know \ifcat yet?)

And the next daughter vomited, I think :( This evening isn't to my liking :(

@Skillmon There's a definite lack of cats on this chat. Ducks and marmots and monochrome Englishmen, but no cats.

@Skillmon Oh. Sorry to hear that. Hope you're not next.

@Skillmon you should have given her Hawaiian pizza for tea, then she would have been fine.

@ChristianHupfer Ooh. But TeX has no \ifkitten.

@HaraldHanche-Olsen you can use \small\ifcat

@HaraldHanche-Olsen: There you go ... (unfortunately not my cat), but I know the feeling about holding a sleeping ginger kitten....

@DavidCarlisle Oh my, TeX humor at its ... well, fill in yourself ;-)

@ChristianHupfer \maxdimen

@DavidCarlisle no, \let\maxdimen\worst ;-)

@HaraldHanche-Olsen: The monochrome Englishman is a fan of cats too ;-)

@ChristianHupfer even better than ham and pineapple on pizza

@ChristianHupfer Well I know about other people's cats. Every summer I babysit my sister's cats for a few weeks. Except one of them prefers to live apart from everyone and only comes sneaking in to eat at night.

@DavidCarlisle Yes, the famous British cuisine ... Spam and Cats ;-) Spam with Cats, Spam Spam Spam and Cat ...

@HaraldHanche-Olsen Currently we don't have a cat. But that small fellow in the linked image reminds me of my ginger cat about 15 years ago, when the mother cat placed their two kittens in our house, just for fun, in order to stay. One was the ginger one and the other one was less ginger: A black tom cat ;-)

@ChristianHupfer awwww

@HaraldHanche-Olsen I summon @cfr to provide cats in this chat! :)

@PauloCereda Well, of course “chat” is French for cat … hmm …

@HaraldHanche-Olsen ooh le chat

@HaraldHanche-Olsen: how is cat in Norwegian?

@PauloCereda katt

@PauloCereda Mais oui ou la chatte ...

@PauloCereda: Die Katze ... in German ...

@ChristianHupfer sacred coeur

@ChristianHupfer cat pizza

@ChristianHupfer Oh yes, as in Katzenjammer.

@ChristianHupfer don't let our Italians read it phonetically. :)

@DavidCarlisle I don't buy this pizza, it is sc r at ched ...

@HaraldHanche-Olsen Exactly...

@DavidCarlisle cat sitting seductively on top a pizza...

@PauloCereda A flying pizza. In space.

@HaraldHanche-Olsen until now I feel well (except my nose)

@HaraldHanche-Olsen I have no idea: it was a google image search for spam and cat pizza:-)

@HaraldHanche-Olsen Don't you know the famous Cat Pizza Galaxy? Look up the NGC ... ;-)

@HaraldHanche-Olsen ooh space-time pizza

@egreg is good at cat-egory theory. :)

@ChristianHupfer NINTENDO GAMECUBE

<3

@PauloCereda There are kittegories in mathematics too: They are small categories.

@HaraldHanche-Olsen ooh I need to study it

@PauloCereda Small just means that the objects in the categories form a set. That set could still be kind of large. Like an inaccessible cardinal or something.

@HaraldHanche-Olsen Ah cat is the more general, isn't it? I remember something from a keynote.

@PauloCereda No, Naughty German Computer (Scientists)

@PauloCereda Just like all kittens are cats, but not all cats are kittens.

@ChristianHupfer ooh naughty Germans

@HaraldHanche-Olsen but if we consider a kitten as a fixed point, we can use aging as a recursive function, then a cat would be technically a kitten...

@PauloCereda Yes... that's what you read ... you perception is very selective :-P
