@yo' -- There are people of many persuasions who perform despicable acts. A lot of them seem to be active now, unfortunately. One hopes that voters see through their lies and self interest, and vote for the future in the next election. I like the philosophy that one should consider the seventh generation when making such decisions. And in the meantime, just try to be a decent human being.

@DavidCarlisle I tried to descripe my problem here:

Hello all! Please consider this MWE:

On the slide 5, after "Some text" there is a innecesary huge space, I don't know why it creates that extra space. Could you help me by deleting it please? Thank you!! This is the extra space:

@barbarabeeton hello Barbara and nice to know about that article!

Seeing those faces makes me happy, beacuse I can put a face into a help. Should I speak to a psychologist?

Why was there so much call that meeting?

@UlrikeFischer saw it, thank you! I was about to write something along those lines when it occurred to me that it would be better if you spoke for yourself :)

@Just_A_Man I do not know in other countries, but here in Spain receiving a full anonymous donation can be an infinite source of problems, both fiscally and ethically (I am a professor --- go figure). Maybe you can send TUG a box of props (latex ducks or bears or squirrels) and let TUG sell them for fund-raising? I would bid for one... @barbarabeeton @samcarter_is_at_topanswers.xyz @UlrikeFischer ;-) ;-) ;-)

@manooooh The space is to leave enough room for the item on slide 6. If you don't want this space:

\documentclass{beamer}

\usetheme{Copenhagen}
\geometry{paperheight=110mm,paperwidth=140mm}

\setbeamertemplate{items}[circle]

@UlrikeFischer Drat: I'll look at this

@Rmano TUGBoat could sell these:

@samcarter_is_at_topanswers.xyz Yep! (Although I'd like a squirrel...)

@Rmano here you go i.pinimg.com/originals/e8/a9/3e/… :)

@samcarter_is_at_topanswers.xyz ooh

@samcarter_is_at_topanswers.xyz uh-oh

@PauloCereda ^^^ although I would classify "teaching MS office" as torture (to me and the others)!

@samcarter_is_at_topanswers.xyz oopsie. :)

@PauloCereda :)

@samcarter_is_at_topanswers.xyz I was just about to say that myself. Makes an otherwise great answer lose credibility :-)

@PhelypeOleinik :) maybe it is there to check if people read the complete post?

@samcarter_is_at_topanswers.xyz Like a jumpscare in a movie scene that checks if nobody slept?

@PhelypeOleinik Exactly :)

@PhelypeOleinik ooh

@PhelypeOleinik updated. :)

@PauloCereda Looks great ;-)

@PauloCereda :D

"I hope this email finds you well"
- trite
- boring
- if i were doing well i wouldn't be reading email

"This email has found you."
- always true
- deeply ominous
- implies more emails might also find me, which i am suddenly quite worried about

Funny (OT) problem: The printing house converted our MetaPost circles into 32-gons. The files look good when we printed them on our printer at work.

That's fun. Is there a LaTeX forensic team around? (Checked. You have to run in nonstopmode, clearly)

Something related to mathpalette, I suppose...

@Rmano Overleaf is very good at hiding errors :)

@samcarter_is_at_topanswers.xyz ooh

@samcarter_is_at_topanswers.xyz Yes, I think they should grow the font of the error indicator, say, 10 veces. Or put a red background in the PDF when there are errors...

@Rmano Personally I think they should show the log file instead of the pdf if there are errors...

... but probably a lot of people would suddenly realise there are errors and flood both their support as well as all the tex Q&A sites with questions "my pdf suddenly disappeared"

@Rmano how about making the entire Overleaf BG red if there are compilation errors.

@cis You mean you want the intersection to be colored instead of white?

@cis The issue is that the straight line has the wrong direction. Select the line segment, go to Element>Reverse Direction. That should fix it. (You can also select counter-clockwise directly or try "Fix directions", but I never tried the "Fix directions" option.

Basically all paths must be clockwise or counterclockwise, the other direction is used to delete already drawn stuff. Conventionally, "positive" paths are counterclockwise.

@daleif yes, that is also a nice idea... @samcarter yes, but this means that they will have errors unnoticed when submitting ... (although I think that overleaf will not do the automatic submission thing if there are errors).

@PauloCereda -- I wish I could upvote your answer (even with the M$ reference), but alas, my laptop prevents me. The message is clear -- pay it forward.

@PauloCereda -- the reason why DEK doesn't read email.

@barbarabeeton aw <3

@barbarabeeton about to send you an email. There's hope! :D

@mickep -- And this is one (good!) reason why AMS still has an inhouse print shop.

@cis Why do you get them that way? How do you create them in the first place?

@barbarabeeton /poke

But it seems to work well with "reverse direction":

@UlrikeFischer @PauloCereda I got mail :D Thanks pals! <3

@yo' Yaaaaaaay

@MarcelKrüger is unicodedata.txt loaded by pdflatex in some cases?

@UlrikeFischer I do not think so, at least not by default packages.

@MarcelKrüger I thought so. I wonder what the guy with the miktex problem is actually doing.

Also the default TeX parser in load-unicode-data.tex starts with

% The data can only be loaded by Unicode engines. Currently this is limited to
% XeTeX and LuaTeX, both of which define \Umathcode.
\ifx\Umathcode\undefined
  \expandafter\endinput
\fi

@barbarabeeton It is our "inhouse" print house at university. Well, almost inhouse. In any case, I redrew the circles with more samplepoints (than 8 that fullcircle gives), and it will look good. But it was strange!

@UlrikeFischer I was wrong. expl3 (and therefore LaTeX) does read UnicodeData.txt for legacy engines.

It's required for the case-changing code.

@MarcelKrüger when it is loaded? I checked the log of a format creation and found no trace of it.

Or do we add it to the expl3 code?

In expl3-code.tex, before line 28193 in the last release, we have

@BambOo quack

@UlrikeFischer It might not appear in the log because it is only read using \read and friends and not \input.

@all Does anybody know if there is a list of all known LaTeX temporary file extensions ? Same goes for LaTeX defaul filetypes (.cls,.sty ... ), but I guess this list already exists somewhere

@PauloCereda quack back at you

@BambOo As starting point: github.com/github/gitignore/blob/master/TeX.gitignore

@BambOo :)

@samcarter_is_at_topanswers.xyz ooh you were fast

@PauloCereda by the way, I documented a bit the interaction between arara and VSCode extension LaTeX-Workshop, would you care to have a look github.com/James-Yu/LaTeX-Workshop/issues/2139#issue-630794056 ? Maybe it could be useful for other arara users

@BambOo oh thank you! I will take a closer look later on!

@PauloCereda, I think I will append this in the LaTeX-Workshop wiki, but it may be useful to add this to the arara documentation as well.

@MarcelKrüger ah, secret file ;-)

Is updating TeXLive one way to get the updated dvisvgm binary? Or do I have to download it and manually replace the old one?

@samcarter_is_at_topanswers.xyz thanks !

@PauloCereda :)

@BambOo You're welcome!

@TooFatManNoNeck dvisvgm is a binary, so the version in TeXLive will normally only be updated in the next release.

@MarcelKrüger Did you mean the next release is TeXLive 2021?

@TooFatManNoNeck Yes. But TeXLive 2020 already seems to include dvisvgm 2.9.1, so there doesn't appear to be a newer release anyway.

@MarcelKrüger: github.com/mgieseki/dvisvgm/issues/136

@TooFatManNoNeck That change has been added to the code, but there hasn't been a new release of dvisvgm since then. If you want to use the changed code you either have to wait for a release or compile the modified code yourself.

@MarcelKrüger: OK. Thank you !

BTW: I found both fonts in my TL2020-distr.

@barbarabeeton Barbara, I have looked into the two issues and have scrolled through a few contributions. I might be missing something, but does any part directly relate to the topic of tex.meta.stackexchange.com/questions/8600/… ?

@barbarabeeton Off-topic: as for the fact that TUG indeed makes tremendous progress: no doubt, I acknowledge the effort, and I would support most of it if I had enough resources to do that anonymously.

@barbarabeeton ... Of course, in my typesetting, I run into my own subset of issues that require resolution, such as absence of the possibility to search text in .DVI and Postscript files, getting quite a few old XETEX bugs fixed (even if the bug-report originator can no longer be tracked; I'm afraid I'm partially responsible), finally improving support for sans-serif upright normalface Greek in [xe|lua]latex, ...

@barbarabeeton ... the absence of a babel-aware grammar checker or spellchecker for multilingual LaTeX source files, and so on. I could talk hours on this, as anyone here, I guess.

@Just_A_Man -- No, there's nothing in TUGboat at all (that I'm aware of) that directly and vigorously encourages rewarding contributors. My philosophy is to try to make the publication as interesting and useful as I know how, so that readers will find the organization worth joining because they're likely to find other people there with similar interests. I thought those particular issues were sufficiently representative of the corpus.

@barbarabeeton I see. I do see an enormous variety and an exorbitant progress in comparison to what I could do alone in my lifetime. No doubt. I acknowledge this effort a lot and I feel ashamed for using this without any contributions to it so far except writing bug reports....

@mickep -- That certainly does sound strange. Sounds to me like the print shop's RIP doesn't strictly follow the definitive specs.

@barbarabeeton ... Still, I feel urged to say (if anyone would care about my opinion) that compared to what huge software corporations (Google, MS, Apple, ...) could do if they decide they wish to invest effort into typesetting research-level texts, my best guess is that LaTeX risks staying behind: the core typesetting language continues to get increasingly outdated. I don't know myself how to address this problem, and I'm definitely not at the level to address it.

@barbarabeeton Anyhow, here is one thing I suggest: some TeX-related organization (TUG, Dante, etc.) should be found in smile.amazon.de (the German site!!!). It is not the case as of today.

@barbarabeeton I don't know whether I will use smile.amazon.de myself (I have to check how anonymous it is first and wait until TUG/Dante/... gets into it), but I have no doubt that many research-level folks from Germany would use it once they get aware of it.

@Just_A_Man -- @Just_A_Man -- Your suggestion seems worth looking at by the boards of Dante and TUG; I'll carry it on to TUG; maybe @UlrikeFischer can do the same for Dante.

@barbarabeeton See tex.meta.stackexchange.com/questions/8602/…

Where can I find documentation on what &[40pt] does in tikzcd?

It isn't mentioned in the tikzcd manual as far as I can see.

re "Overleaf is very good at hiding errors": so is TeXStudio! My efficiency tremendously increased the time I stopped reading TeXStudio's error summary but instead TeX's raw log.

@ComFreek It sets the space between the two columns. You can find it in TikZ manual, the section about matrix

@CarLaTeX the professore told you that.

@ComFreek I wholeheartedly agree that the error parsing in texstudio is not helpful, but at least one can see that there is some red text on something like 15% of the screen - the user has a good chance to notice that there are errors. In overleaf the only indicator is a tiny red square in a corner miles away from focus of the user - they often don't even notice it

@barbarabeeton I guess you are right. I talked to the person at the "machine", and we looked in the settings of the print dialogue, but could not find any settings that fixed the problem. It was in the end easier for me to redraw the images in MetaPost, but to loop through the points "denser" in the paths affected.

@CarLaTeX ah thanks! Before reading that (going to do that tomorrow), do you perhaps already know whether this column spacing is per row or for the whole matrix?

i.e. is \begin{tikzcd}A &[40pt] B\\C &[60pt] D\end{tikzcd} useful?

@UlrikeFischer Are you available this weekend for paid consultancy for some tikzcd positioning? Not sure if I can get it fixed myself tomorrow, need to deliver the talk on Monday morning, though.

@ComFreek hm you know that I don't work with tikz much and that whatever is to do I have to look up in the manual first?

@UlrikeFischer You should hire Prof. van Duck!

@barbarabeeton ^^^he is preparing

@cis -- I have no idea how to fix this problem, but observe that the present result would probably serve admirably if you had need for a design for the point on a poison dart.

Hey guys

Got any clue how to write the del sign which is used for partial differential equations?

@AaronJohnSabu -- Are you looking for \partial or \nabla perhaps?

Wow! A new version of the Comprehensive LaTeX Symbols list has just been announced on ctan-ann! What a lot of work, and greatly welcome and appreciated! Kudos to Scott Pakin!

@barbarabeeton \partial helped. Thanks a lot

@UlrikeFischer -- Someday I hope he gets to meet my bunny in person. (Bunny has accompanied me on trips for years and years, but I've never brought her to a session; she's often too disruptive. I do try to find a good window though, so she can watch what goes on outside.)

@barbarabeeton Bär is very good at making friends ^^^

@UlrikeFischer -- Oh, that is obvious! Bunny is looking forward to it. (She's quite restive. So far this year, three trips have been cancelled, and that's not counting Rochester.)

@UlrikeFischer Oh, prof. van Duck!

@UlrikeFischer not invited on to the ark though. I fear they are doomed.

@ComFreek It is for the whole matrix, you can use it only in the first row (not in the second)

@DavidCarlisle That ark is special, also unicorns were invited (and, of course, bears and ducks). The painting is in San Maurizio in Milan magazine.dooid.it/destinazioni/lombardia/…

@CarLaTeX -- What a magnificent building! I hope to visit Italy someday. (When I had a chance many years ago, I was in Strasbourg, but it was so hot we decided to go north instead, and ended up in Helsinki, a place I'd like to revisit. But I guess it won't happen soon, since Europe won't let us in.)

Hi folks. How is everyone? Aside from not being able to go anywhere, I mean.

@barbarabeeton You should! When it will be allowed. Today I've gone to my office after 4 month, there were very few people in the city center, so sad to see Milan like this

@ComFreek Prof. van Duck could help you: tug.org/TUGboat/tb41-1/tb127duck-matrix.pdf

@FaheemMitha Hi Faheem! I'm well, hoping that this nightmare will end soon

@barbarabeeton it was really nice and worth the visit!

@CarLaTeX Hi. Well, you're doing better than us here.

@FaheemMitha You're in India, aren't you? I saw on TV the situation is serious

@CarLaTeX Yes, Bombay, India. And yes, the situation is serious.

@FaheemMitha :'(

It's even more serious for Bombay, and some other big cities, like Delhi.

We actually had a coronavirus case in our compound.

@FaheemMitha so sad

It sounds like the worst is over for Western Europe.

@FaheemMitha Yes, the situation is much better now. The problem is economy, at the moment. You know, no tourists when tourism is the 12% of our GDP

@CarLaTeX Yes, tourism is currently dead almost everywhere.

And I suppose tourism is very important for Italy.

@FaheemMitha Yes, we have cities that lives more or less only for the tourism, like Venice

People come from all over the world to visit Rome and Florence and Naples and Venice and Tuscany and...

I've seen places like Tuscany in films. It's hypnotically beautiful.

@FaheemMitha -- Remember to wear your mask, keep a good distance away from others, wash your hands, don't touch your face, and try to keep your spirits up. It's not easy, and persuading everyone else to do the same is even more difficult. But hang in there.

@FaheemMitha Yes, and most of them are from US or China...

I once watched this film called "Stealing Beauty". It was set in Tuscany, i think.

I had difficulty following the film because I was so taken with the landscape.

@barbarabeeton Thank you for the advice. I haven't left my home in months, except for occasional visits to banks.

@FaheemMitha Tuscany is loved by English and American people. Sting has a house in Tuscany

And I touch my face quite a lot. It's a hard habit to break. I do wear my mask if I venture outside. It's actually currently a govt rule, anyway.

I'm pretty sure I wash my hands more than most people.

@CarLaTeX Only English and American people? :-)

How do Tuscany people feel about it?

@FaheemMitha Not only, but in particular :)

@FaheemMitha They are very happy to have rich tourists (and they miss them very much now)

@CarLaTeX Everyone likes rich tourists. They love them here. And they love to rob them.

@FaheemMitha I think it's a common factor :)

@CarLaTeX And really I meant, how do Tuscany people feel about Tuscany?

@FaheemMitha -- The other thing is to listen to news carefully, and believe only what reliable sources are saying. There are too many idiots out there who are spouting nonsense. And people who are desperate can't be blamed for wanting to hear that things are getting better and there's nothing to worry about.

@barbarabeeton Our govt lies a lot, but it's clear the situation is very bad. And this virus is only one of India's problems. In a way, it's a relatively minor detail. And a transient one.

@FaheemMitha They love Tuscany. Of course, they hate each other, for example people from Pisa hate people from Livorno :)

@CarLaTeX That's a shame. The hate, I mean. But why?

@FaheemMitha -- That's a good question. Do people who are born and grow up in a place want to come back and spend their lives there, or return after they've had their adventures and made their living where the prospects for getting rich are better?

@barbarabeeton Sure, but my question was simpler and more specific. Just how people living there like the area. It looks beautiful, but one can't eat the view. And no doubt there are disadvantages.

@FaheemMitha Since the Middle Ages, when every town was a dukedom and the were fighting each other every moment, but now it's more for fun

I know much of Italy is quite poor. The North is richer than the South, or the other way around, I can't remember which.

@FaheemMitha The North is richer

@CarLaTeX Ok.

@barbarabeeton And how are you doing? It's looks like cases are falling across the United States, but graphs can be misleading.

@FaheemMitha However, I saw much more poverty when I went to the US. There are not so many homeless here in Italy (at least, before the virus)

@CarLaTeX Yes, the US probably has more poverty. It has a very dysfunctional political system. Probably comparable to India.

Of course, India is much poorer, in some sense.

@FaheemMitha Yes, perhaps it is the difference between the rich and the poor that make US and India similar

(I never visited India, though)

@CarLaTeX They both have extremely skewed wealth distributions. And probably for similar reasons.

@FaheemMitha Yes, I think so

And also for those reasons, the virus is creating havoc in both places, whereas Western Europe is recovering faster, because it's generally more functional. With the exception of the UK, perhaps.

@FaheemMitha -- Rhode Island is in the "downward" phase, and there are still pretty strict guidelines for keeping it that way. The beaches and other tourist areas are very tempting, but the governor is listening to the medical experts, and refusing to let things open up too soon. There is also serious encouragement for people to keep track of their personal interactions, so that if someone does get a positive diagnosis, their contacts can be traced.

The richest man in India, Mukesh Ambani, just increased his wealth dramatically. He's now one of the 10 richest people on Earth. This happened in the last few months, during the pandemic. During this time, millions of Indians are starving to death because they don't have any money.

@barbarabeeton Glad to hear things are improving there.

It's not hard to understand why things are bad here.

Did I mention that we had a case in our compound? I spoke to a couple of nurses who came here from the BMC. Do you know how many people in the compound were tested? Zero.

Forget about contact tracing. They did (sort of) tell her family to stay in quaratine, though I think it's self-imposed. No enforcement.

@FaheemMitha -- But that isn't true of many areas, where some people (especially politicians) want to open up at any cost. @CarLaTeX is correct about the difference between rich and poor. The economics are such that in this environment, many people are going to lose their homes, whether it's rent or mortgage that they can't pay. I'm far from a socialist, but the idea of enforcing a living minimum wage, and making decent health care more readily available and affordable make a lot of sense.

@barbarabeeton I'd probably describe myself as a socialist, though it's not a well-defined word. And I think most people in the US have basically no idea what it means.

I hope this catastrophe at least pushes the United States torwards some degree of sanity in health care.

@FaheemMitha -- One of my high-school friends went to live on a kibbutz for a year; I think that qualifies as a socialist society, at least when it works as intended -- to each according to (real) needs, and from each according to abilities. Share for the betterment of all. Don't accumulate just for the sake of accumulating (greed). Greed is not good.

@barbarabeeton yes new rule: you need to be able to speak English first.

@barbarabeeton I don't know if a kibbutx is socialist. According to Noam Chomsky, it's where the Israeli military like to recruit from. Doesn't sound very socialist to me. But like I said, it's not a well defined word.

@FaheemMitha -- We can all hope for that! But I have my doubts, since the Senate majority leader is unwilling to do the job he was elected to do (according to the Constitution), and has done so for longer than the present administration has been in office. Washington has always been a place of cronyism, but I don't think it has been as blatant, or inept, than those now in power.

@barbarabeeton I'm sure it won't be easy, but there has been significant movement in that direction in recent years. Though it's up against enormous entrenched power.

@FaheemMitha -- I'm talking about the situation of about 60 years ago. Things have changed.

@barbarabeeton You mean with respect to kibbutzim?

@FaheemMitha -- Yes. There was still some idealism in the world then.

@barbarabeeton I don't know anything about kibbutzim. Just what I read. But things in Israel also seem to be deteriorating.

Not that it was ever good.

@FaheemMitha -- I'm just hoping the Democrats stay under the radar until election time, and let the present President dig himself a hole so deep that he can't get out.

@barbarabeeton I'm no fan of the Democrats. I guess they're marginally less awful than the Republicans, who are really disgusting.

And your President. It's like he's trying to win some prize in being as loathsome as possible.

@barbarabeeton Anyway, time to go to sleep. It was nice to chat with you. And @CarLaTeX, you too. Be safe.

@FaheemMitha -- True that things were always a bit shaky, but there was once an Israeli general who spoke Arabic nearly as well as he spoke Hebrew, and didn't have an abiding hatred of anyone who didn't agree with him.

A different question: is there a way to take in a parameter and not expand it at all, something similar to how \string\command\unexpanded{{#1}} can be used? Whatever my queries I ended up trying to read about expansion in detail, but my head inevitably could not cope.

@FaheemMitha -- People tend to forget that, during WWII and the following decade, the predecessors of those Republicans were the "Dixiecrats", who jumped ship when segregation was "outlawed". (Much good those laws did.)

@DavidCarlisle -- Some of us try, we really do. But you can do something useful here, and answer @Thor's question about expansion.

@FaheemMitha Good night!

(I would say that understanding expansion to the extent it can become knowledge seems far more feasible for me, and perhaps in general, than understanding how so much of what the current U.S. president does is accepted by such a large political base.)

@Thor isn't that what \unexpanded does? I don't understand the question if not:-) (@barbarabeeton)

@egreg not necessarily the word I would use

@DavidCarlisle Just envy

@DavidCarlisle You should have a look on how it was done in the first version.

@egreg I didn't look at the package just now but why ` \setTransitionsForabc` defined with two arguments it doesn't use? \newcommand \setTransitionsForabc [2]{\abcClasses } ?

@DavidCarlisle You should ask that to the original author. I only made the loading slightly more efficient: it used to take about a minute to load.

@egreg about 14min quicker than article.sty with sbtex if I recall correctly:-)

@DavidCarlisle quack

@DavidCarlisle \abcClasses expands to \do{abcstuff}\do{abcmorestuff} in that package

@DavidCarlisle I'm sorry, I wasn't very descriptive in the issue. My pickle is that I try to get parameter #1 entirely unexpanded, using it in a parameter to renew another command which is later used to write the hopefully still unexpanded contents to a file. It is not my own code to begin with, and as such I am possibly a bit out of my depth. (I am trying to adapt tex.stackexchange.com/posts/342333 for LuaHBTeX)
