@Kurt off-topic: "did you saw" translates to "Hast Du gesägt", "did you see" to "hast Du gesehen".

@marmot really? Ups. Well my english is not good, I know. Thanks.

@PauloCereda Look at Google Doodle today ^^^

And happy Father's Day to all the Darth Vaders here!

@CarLaTeX no doodle here:-)

@Sebastiano I didn't vote up or down but to be honest you should not be surprised to get a downvote for such a question. As you have been told 1000 times you should provide code people can use to test answers, you just have a fragment there, you link to an older question but you didn't provide any usable example in that question either. Downvote seems not at all an inappropriate action and your reference to the person as wicked seems quite out of place (and not a suitable comment for the site)

@DavidCarlisle You're too worried for the Brexit

@CarLaTeX brexit allows us to set our own duck-free fathers' day at a different time, Finally some benefit is discovered.

@DavidCarlisle Non tutto il male vien per nuocere :)

@CarLaTeX amen

@DavidCarlisle lol

@DavidCarlisle Good morning to you. Personally, when I don't enter a complete code it's simply because I have a very long code and I can't select it. Badness is not in my soul and I am referring to someone or someone who systematically dislikes him. It is no coincidence that for more than a year I have been the subject not only of offenses but also of free reprimands.

@Sebastiano Most questions can have a reason MWE without it being over-long

@JosephWright Kind Joseph, I understand the need for a complete code. I also believe that each of us has our own character and sensibility. I couldn't enter a complete code in any way because the book I'm writing has a myriad of codes that intersect with each other.

@Sebastiano Yes, but each question on the site is meant to be self-contained and useful to multiple people. Interacting code is part of a MWE where it creates an issue. That's rather the point.

@DavidCarlisle Enjoying Brexit? ;)

@Sebastiano You should try to create a minimal example which reproduces your problem, not posting the entire book nor code snippets.

@CarLaTeX ooh

@PauloCereda Is there in Brazil, too?

@PauloCereda Good morning.

@CarLaTeX no :(

@Sebastiano hi

@PauloCereda So only Italians will have a drake father's day!

@CarLaTeX oh no

@CarLaTeX If you look at my questions, there are very few that do not contain a complete code. I understand very well but I can not select the parts that interest me late. :-( and I apologize.

@JosephWright The United Kingdom will formally leave Europe, but in my view we are all Europeans and we should help each other.

@DavidCarlisle I think - but it is simply a point of view - that empathy is important.

I extend my sincere greetings to all of you.

@Sebastiano no idea what you mean by that comment, how is describing people as "wicked" showing empathy?. All I can suggest is that you read Ulrike's answer that you accepted at tex.stackexchange.com/a/433336/1090 and then explain how your latest question shows that you are actually following the "General Remark" that you accepted there?

@Sebastiano No, there is really no excuse, you should not post questions that are so poorly constructed. For a new user on the site it is OK to let some pass, but you have been asked over and over again not to do that and you should expect to be downvoted if you continue to ignore these requests.

@PauloCereda try here:

google.com/doodles/fathers-day-2019-multiple-countries

@DavidCarlisle ooh thank you!

@Sebastiano with all due respect, you need to understand that @DavidCarlisle raises a very important point. You should not justify very objective observations from high ranked users and moderators with subjective claims (e.g, raising up feelings or moral principles). You know the rules, and you must abide by them.

That's how the site works, and no one is excused from the rules.

@PauloCereda and so says Erskine May

@PauloCereda I am not able to select the parts that I need of my long code that I need to compile. I have no intention of breaking the rules. But for almost two years I have been offended by unknown users probably because of the too many reprimands I suffer.

@Sebastiano again and again you do the same thing, you post poor questions that on most sites on the network would get dozens of downvotes and then accuse others of wickedness or bad intentions if they downvote your questions. You should accept responsibility for your own actions and stop blaming others all the time.

@DavidCarlisle I changed the Ulrike code due to compilation problems after adding more commands. So I don't currently use that code.

@Sebastiano You could still follow the text of that question which pointed out that you should not post questions of this form. and then you link to that and do exactly the same thing again.

@DavidCarlisle I'm bothered to get free reprimands and offenses for two years. I teach my students the correct rules. Why should I break the rules here?

@Sebastiano exactly why should you, and when you do people will point it out or downvote. It is not the worst thing anyone can do but do not complain when you get the downvotes and do not blame others for wickedness if they are simply pointing out for the 1000 time your error.

@Sebastiano If you ask a bad question (and your current question is not good) then you shouldn't complain about a downvote.

@UlrikeFischer Hi, :) good morning.

@UlrikeFischer @DavidCarlisle @PauloCereda I do what I can when I can. Sometimes questions are good for me and sometimes I don't. I complain because reprimands that are not made by the heart (empathy) attract the attention of haters to me. That's why I'm complaining.

@Sebastiano stop complaining and stop using rude comments such as hate, it is your choice to post bad questions and so your actions that attract downvotes. stop blaming others.

Let's just forget about it.

A greeting to all. Good work and good latex

@Sebastiano fine but please stop posting complaints here, take them somewhere else.

There is a whole shop full of ducks in Bangkok!

When using lualatex, can you ask it to write its otf cache somewhere specific? Related to tex.stackexchange.com/q/480119/3929

@daleif I saw the question but it is a bit curious. The cache is written to texmf-var and if this doesn't exist other stuff won't work either. Perhaps @MarcelKrüger has an idea what's going on ...

@UlrikeFischer the question of course then is whether the webserver user (www-data) is allowed to write to texmf-var, probably not. Must admit I've never run lualatex from a webpage, only pdflatex.

@daleif well one could test the writing of texmf-var e.g. by forcing a creation of a pk-font. But if it doesn't work, where are the formats?

@UlrikeFischer the formats are presumably not being generated on the fly?

Do you have an example, then I'll try it on my desktop box. Here TeXLive is owned by me, but not writable by www-data

@daleif probably not (but miktex does it, if it realize that the format is outdated), but they must be somewhere. So texmf-var should exist.

@daleif for pk-creation? Something like this should do it:

\documentclass{article}
\pdfmapfile{}
\begin{document}
\font\test=cmr10 at 17.35pt \test blub

\end{document}

@UlrikeFischer I'm sure it exists, but shouldn't it be writable for the user

@daleif I just found this github.com/sharelatex/sharelatex/issues/450

hmm, I get an error on \pdfmapfile

@UlrikeFischer That was exactly what I was hinting at in my comment on the question

@daleif ? with pdflatex? Or did you try with lualatex, that won't work.

@UlrikeFischer ohh, I was using lualatex, I'll try pdflatex. Do you have one for lualatex?

@daleif well as the question implies that already the loading of luaotfload fails, any latex example should do it.

Best wishes to all the fathers in the world and good name days for those who are called Joseph.

@JosephWright Good name day.

@daleif Good morning also to you. Hi everybody.

@UlrikeFischer hmm, a simple hello world does not trigger anything.

@Sebastiano Good noon...

I am using TL2018 frozen. But that should not matter

@daleif Perhaps you need to try to use a font that it isn't already in the cache.

@UlrikeFischer Would you upvote @JosephWright's answer at tex.stackexchange.com/q/468973/4427 so it's removed from the unanswered list or should the question being closed as “off-topic as bug report”?

@UlrikeFischer I upvoted it to cancel the downvote.

@UlrikeFischer I always fail when I try to use OTF font from TL in lualatex, always tend to have to use full paths quite annoying.

@egreg upvoted

@JouleV do you have some proposals on ways to solve the diagonal red-line?

in this question: tex.stackexchange.com/questions/480219/box-half-filled-color/…

@UlrikeFischer Most likely that's exactly the problem: luaotfload can handle a non-existing texmf-var, but if it exists it has to be writable. Except if an explicit cache dir is given through $TEXMFCACHE, so the fix is to set $TEXMFCACHE to some sensible value.

@daleif ^^^^ (or to set texmf-var to writable, that's probably better).

@MarcelKrüger could luaotfload catch the case of a non-writable texmf-var and give an error and not simply die as it seems to do now?

@UlrikeFischer The advantage of setting CACHE is that you do not have less risk of affecting other stuff, texmf-var is also used for the system-wide var directory containing formats and stuff.

@UlrikeFischer Certainly, but this would have to be changed in fontloader-basics-gen.lua which we import from the fontloader AFAIR, so we either have to carry a patch or ask for an upstream change.

@MarcelKrüger I meant that it is better as if texmf-var is not writable other stuff (like pk-creation) can fail too. It doesn't make much sense to make this non-writable.

@MarcelKrüger no, patches should be avoided. I guess we could ask upstream at some time. But not now, I'm too busy with the tagpdf update ...

@daleif Good!

@Raaja I tried your code and the red line was not there, but when I saw the output png generated by latexmkrc the red line appeared. So the easiest solution: take a screenshot instead of exporting to png ;-)

@UlrikeFischer You could consider it to be a feature when you can't generate pk fonts :P

I just got a palindrome

@MarcelKrüger well you couldn't generate tfm either ;-)

@JouleV Huhh I see, so its a Pdf reader issue. However, I dont generate .png. Instead, I take a snapshot from my adove reader.

@JouleV Nevertheless, thanks for the update though :)

@Raaja Then I just got another surprise today :))

For the sake of completeness, this is what I got with my viewer

and this is what I got from latexmkrc

but its worth having these sort of surprises :)

@Raaja :)

@JosephWright quack

@PauloCereda Quack quack

@CarLaTeX -- Not here either (either yesterday or today).

I just learned that Karen Uhlenbeck, who just won the Abel Prize in mathematics, had Dick Palais for her thesis adviser. Dick is the person who persuaded the AMS that they should be using TeX, and is the reason that I'm involved in this whole mishegas. Amazing! Details about Uhlenbeck and the prize here: quantamagazine.org/…

@barbarabeeton Yay!

@barbarabeeton Only in Italy :)

@CarLaTeX -- Somebody (David C?) linked a page with a map, and it looked from that like maybe Ecuador was also celebrating. (One of the countries on the Pacific coast of South America.)

Hi.. I am wondering if I am going mad. It seems the vertical arrows in my tikz diagram are a very weird shape but all the other arrows are fine bpaste.net/show/ebbfa9721171 . Am I right about that?

@PauloCereda Calm down. It's Dick Palais, not Duck Palais.

@barbarabeeton Interesting to note that she said that if she were five years younger, she might not have made it to where she is now. (I forget where I saw that.) And “mishegas” was a new word to me. My dictionary suggest the spelling “mishegaas” or “meshugaas”, though. Yiddish seems to be hard. Impressive that Quanta Magazine managed such a good article with only a few hours' notice.

@Anush You're not going mad. I think it's that the arrow is too short?

@barbarabeeton An employee at the academy in Oslo managed to leak the name of the laureate an hour early to all Norwegian mathematicians, but I suspect a computer problem. It was probably preprogrammed to go out at noon, but got sent (exaclty) an hour early. I can only speculate about the reason. Upcoming daylight saving time?

@Anush For example if you make the row sep of the table 10pt, the arrows look fine.

@HaraldHanche-Olsen -- Daylight saving time arrived here more than a week ago. (I've finally recovered from the annual government-mandated jet lag.) I think that's a good guess. Regarding the article in Quanta Magazine, is there any prognostication regarding who possible nominees may be? (I seem to remember all sorts of speculation regarding Nobel nominees.) The magazine may use such a list to prepare drafts in advance.

@barbarabeeton Possibly, but the committee surely is pretty good at avoiding leaks, and the list of nominees is not public. But of course, anybody is free to make more-or-less educated guesses.

@barbarabeeton ObTeX: Reading this article, I am interested to find several instances of this: \( \dots \). On enabling some javasctipt (I am running the umatrix extension), they teurn into …, though.

@AlanMunn oh thanks. Let me see

@AlanMunn yes you are right.. but what can I do?

@HaraldHanche-Olsen mathjax seems a bit excessive just to typeset ... :-)

@DavidCarlisle :)

@DavidCarlisle what's worth doing is worth overdoing.

@AlanMunn I'll post on main

@HaraldHanche-Olsen oh

@HaraldHanche-Olsen -- Thanks for the link to that article. I noticed, about the \dots, that they aren't always uniformly spaced. The general spacing is comparable to \frenchspacing, but I didn't see any places where that would be confusing. I did, however, see a dreadful hyphenation -- "mathem-atics". Yeccch. (I'll not comment on the "societal" aspects of the article, which I found familiar but not on topic here.)

@marmot thanks!! Your solution was very easy and precise!! I also tried it but keeping column sep=8pt, so that is the reason for the "if we use 3 columns instead of 2 the output goes crazy" hahaha. What do you want to do with the comments: delete them (which ones)?

@manooooh I think that the consensus in the community is to delete comments after the one getting addressed in them read them. Of course there are exceptions.

@marmot of course, there are exceptions (although if we are very technical nobody has the right to say that we have to eliminate or modify what we write as it is under our signature, and any modification could be taken to a judicial case). I already read it, so I guess the rule of deleting them all is true, right?

Hello friends. Usually, I use \setlength{\overfullrule}{5pt} to see the overfull. Is there a way to also see the underfull? i'm not able to find one in my very long document.

@manooooh I just wanted to say that you should only keep comments if you think others will greatly benefit from them. And I am not sure if copyright issues apply to our site, if they did, certain users (some of them with a high reputation score) will be in real trouble.

@Sigur no, although if you add \showoutout the box logging will tell you the box content]

@marmot ok

@marmot please tell me if this question is easy to solve or if I have to google it deeply or, instead, ask a new question. I am trying to draw an arrow from I to AK subjects. However, when I compile the code I get: "! Dimension too large. <recently read> \pgf@xa l.272 } I can't work with sizes bigger than about 19 feet.". I google the problem but I can not find a solution adapted to this MWE (I have already updated all the packages for other reasons)

@DavidCarlisle, where should I put that? On preamble? I got error.

@Sigur you need to factor out my typing first:-) try \showoutput

@manooooh Seems like ducks have very short feet and your path is longer than 19 duck feet. (Let me guess: you confused cm with m somewhere?)

@DavidCarlisle, oh, now no error.... lol

lets see. Thanks

The log is huge now. Should I search for underfull, right?

@Sigur yes find the underfull box message and it will show the full box contents

@marmot I already know that the distance is too long; just add \draw[very thick,lightgray,-latex] (I-Title) to[out=0,in=180] (AK-Title); to the very end of the tikzpicture and compile it. What surprises me most is that in fact the arrow is drawn! but with the error popping up

So I do not know whether to treat it as something that is impossible to open the document (you can see the output and even the arrow is drawn) or an error. What should I do?

So I think it is the section header or subsection header.

@Sigur just read the text vertically Formases....

@DavidCarlisle, yes, it is \chapter{Formas espaciais esféricas quaterniônicas}

@manooooh 19 feet... isn't that close to 6 meters? Who on earth draws such long arrows?

@Sigur but that box is 658pt high so it is the full page that is underfull not the page head specifically

@DavidCarlisle, so, you say that the underfull could be at the end of the page? Maybe a not good place to break the page?

@marmot oh you are right LOL... I do not know... the paper width is 95cm and we are trying to draw an arrow from Level 1 to Level 5, in which the distance is waaaaay much less than 95cm. Should I ask a new question? I said that the arrow is drawn, I do not know what to think

:495640 you have .\glue(\parskip) 0.0 plus 1.0 so only 1pt of stretch glue per pararaph so if you have no display environments and not many paragraph breaks you will not have enough flexibility to make the page flush to the bottom

@manooooh Is the code in your question?

@Sigur you don't have stretch glue after your chapter head? (you might want to use \showoutbox\showboxdepth=1 to cut out some of the clutter)

@marmot nono, you can add the code in your answer if you want. Draw an arrow from I to AK (a subject of Level 1 and of Level 5, respectively)

@Sigur it is the whole page that is underfull, that is it has chosen a page break (or you forced one) and (presumably) \flushbottom is in effect but there is no way to achieve filling the page and it falls a bit short..

@DavidCarlisle, \showoutput\showboxdepth=1 you mean, right? It was useful.

I certainly am not regularly enough on this site lately. Every time I come by, something relevant seemed to have happened...

@DavidCarlisle, I'm almost following the idea. I have 2 underful, the second one is:

So, it means that it is in the page not on a paragraphy, right?
