@PauloCereda their example for running a Bell test docs.microsoft.com/en-us/quantum/… only demonstrates classical correlations :(

Paulo Cereda

@DaiBowen I thought the same. :)

CarLaTeX

@PauloCereda A great success!

Paulo Cereda

@CarLaTeX yes :)

@PauloCereda @CarLaTeX We are working on it to spread it around (someone from Borussia called my husband "Dr. Duck" last weekend ;-)).

Paulo Cereda

@UlrikeFischer ooh :D

@UlrikeFischer Is he van Duck's relative?

Hello everyone

I have an annoying issue compiling a document with quite a few "large" png files

I actually don't know if those are the ones responsible, but anyway

I am using latexmk with xelatex to compile

and at every xelatex iteration, the output gets stuck a long time (>15sec) on [N] (./file.aux)

So a single compilation is like 1 minute for a 3 page document with >10 images

why is that? How can I fix this? I never encountered this in years of using latexmk

Ulrike Fischer

@nathdwek Use \usepackage[demo]{graphicx}. If the compilation is then faster then the graphics are the problem. If not: compile xelatex directly to better see where the delay is (with xelatex it could be also the font cache).

nathdwek

@UlrikeFischer: Yeah graphics are the problem

pngs are about 10M each...

Does this size have an influence on the size of the aux file?

Ulrike Fischer

@nathdwek No. Probably the delay is when xelatex is reading the png to get its size. You could try to get the size and add it to the includegraphics options.

nathdwek

@UlrikeFischer I am not sure I follow what you mean?

Ulrike Fischer

10:45 AM

@nathdwek Try something like \includegraphics[bb=0 0 40 40]{largepng.png} with the correct values for the bb key.

Paulo Cereda

@UlrikeFischer For a moment, I read BB King. :)

nathdwek

This is not a solution as It would require even more time from me to determine the size of every figure I want included

and they're regularly regenerated

Ulrike Fischer

@nathdwek Try it out. If it helps: There are tools to get the sizes.

Q: Dean will not tell me what upcoming meeting is about. What do I do?

I am a tenured professor and co-chair at a small teaching college. I received an email last Friday morning from the head of facilities requesting confirmation of my attendance at a meeting for this coming Thursday, with the subject line "Facilities storage needs and 'MY_DEPT' space." The email wa...

Some of the answers are just incredible.

My favorites are Is it appropriate to do such and such? questions.

Q: What to do with a student coming to class in revealing clothing, to the degree that it disrupts the teaching environment?

Since semester started, a female student has been attending classes scantily clad or wearing clothes that are too revealing, like a sport bra without shirt on top, booty shorts, semitransparent silk blouses without a bra, or even a bikini (this situation happened only once.) She does this once or...

@percusse It is an odd site: I don't think StackExchange works at all for these 'social' things (all opinion based and far too full of dire advice)

Are there any well-documented LaTeX3 packages around? The documentation for LaTeX3 is quite good so far, but it's lacking in examples that use the new interfaces.

Joseph Wright

@Robbie I'm working on a third version of siunitx: a lot of the work there is to provide documented interfaces at the code level. github.com/josephwright/siunitx

@Robbie v2 of siunitx uses expl3 but the idea of 'code interfaces' wasn't fully developed when I wrote it ...

Robbie

@JosephWright I've been using siunitx as a good guide: your code is really nice to read. It does quite different things to what my own packages will though, so it's a bit hard to generalise ways of solving different problems.

I'd decided to jump straight into LaTeX3 for writing my own packages as 2e felt a lot harder to comprehend.

Joseph Wright

@Robbie v2 is a bit of a mess in terms of a defined internal API ...

Robbie

12:37 PM

@JosephWright I've cloned the sources to v3 but I can't test it on my current documents as I also use the physics package, and that has a clash with one of the commands (\qty).

Joseph Wright

@Robbie Ah, the physics package ...

Robbie

The main problems I'm looking at trying to solve are modifying reference labels on-the-fly, and creating environments that contain coffins.

I'm not yet sure how to ask well-formed questions on SE as usually my MWEs are either too big or not detailed enough.

nathdwek

@Ulri

@UlrikeFischer: I ended up making the image generation part also generate decent compressed jpeg for small reports and stuff, that's doing the job for the moment

Joseph Wright

@Robbie I guess the usual: break it down into reasonable 'chunks'

user55789

12:56 PM

@JosephWright I want to update/install a package, TL manager crashes

I have a brand new distro, from september this year ish

And perl just stops working

Reinstalling perl doesn't do anything

And my package (feynmp) makes hideous diagrams

Reinstalling tex live takes the better part of a day, and a lot of pampering (time and effort I am disinclined to invest)

Hence the obvious question: does a quick fix for this kind of issue exist

Paulo Cereda

@user55789 your question sounds too vague, sadly. You didn't even mention which distro you use. :)

user55789

@PauloCereda Latest

And I'm using win10 64 bit

Joseph Wright

1:11 PM

@user55789 TL doesn't use system Perl, so that's not it

user55789

1:28 PM

Hmm at least that's explained

I will try redownloading some fresh files for tlmngr

as a hail mary

David Carlisle

2:18 PM

@JosephWright we gave you \DeclareOption what else did you need? :-)

@user55789 do you get no error message from tlmgr ? also are you using the command line or the gui version?

Joseph Wright

@DavidCarlisle Not what I meant ;)

@DavidCarlisle For example, all of the v2 code is \__ so they really shouldn't be used in document commands, plus the data gets manipulated internally between different parts of the code ...

David Carlisle

@JosephWright oh yes I was thinking of 2e/l3 even though you clearly meant siunitx v2/v3

Ulrike Fischer

2:37 PM

@JosephWright: I think the expl3 documentation could be improved here: tex.stackexchange.com/q/405796/2388

Joseph Wright

@UlrikeFischer Hmm: I think the code might be wrong ...

David Carlisle

@JosephWright wasn't [ + \-] intended ?

Joseph Wright

@DavidCarlisle I've mailed Bruno

David Carlisle

@JosephWright It's good to have someone to blame

Joseph Wright

2:52 PM

@DavidCarlisle Ah, yes: the regex replacement part was wrong too so that was confusing me ..

David Carlisle

3:06 PM

@JosephWright he's appeared on site:-)

Joseph Wright

@DavidCarlisle :)

@DavidCarlisle BTW, I've merged in the l3build multiple test stuff: we should make sure the 2e TU ones are updated ...

A: Cannot get two-column figures to show after the end of text

Unfortunately as well as the bioinfo.cls file itself the zip file distributed to authors includes obsolete versions of many packages that are part of the core latex distribution (graphicx, color) and major contributed packages including natbib, float and stdfloats.sty . Some combination of these...

@JosephWright Can you add an extra link to the duplicate text of this question. This question is a bit more general and would be good to be a duplicate link (as noted in the comments): tex.stackexchange.com/q/361486/105447

@DavidCarlisle I got very busy, but karma indeed. :)

@percusse I like the comment "liberal as your country may be, teaching classes in sandals won't give you any respect as a teacher." No, because you don't get respect from how you dress, you get it from knowing what you're talking about and explaining it in ways that help students learn.

@CarLaTeX A syntactician can't resist a good bit of recursion.

@AlanMunn I didn't even know that syntacticians exist!

Alan Munn

@CarLaTeX We do. There are in fact some very important Italian ones.

CarLaTeX

@AlanMunn Ooooh

David Carlisle

8:38 PM

@CarLaTeX you can't ask whether or not they exist as that's not a syntactic question

Alan Munn

@DavidCarlisle True. But that wasn't a question. ;)

barbara beeton

@AlanMunn -- are you sure this is a good bit? maybe it's only a mediocre bit, or perhaps even a bad bit.

Alan Munn

@CarLaTeX But if you did want to ask the question, we could tell you how to structure it.

@barbarabeeton :D Everyone's a critic.

CarLaTeX

@AlanMunn You have a lot to do here!

@AlanMunn -- yup. (if you want to see a real criticism, take a look at my last comment on the question you linked above re comments on a duplicate link.)

@Brent.Longborough The probability that I consider DejaVu are infinitely greater than me thinking to listening who? At least DejaVu has a rich character set.

just saying...

@AlanMunn I think it was meant to be Oxford coma, running out of breath from enumerating things because of the moist weather

Rich character set

Alan Munn

@percusse Even with my well-honed syntactician skills I can't parse that sentence.

percusse

@AlanMunn one huff two puff three oufff and four....

Alan Munn

@percusse I really wanna know...

@percusse Not your sentence, the one you quoted.

Ahah they talk about the fonts mixed with the band puns

Alan Munn

@percusse Ok. So desperately in need of a 'to' and a 'The', and an 'is'.

David Carlisle

@user55789 hard to give an error if the window is going, I assume the command line version is in the native windows texlive? , tlmgr update --all

Error opening file for writing ".../bin/win32/runscript.dll"

(Ran the .exe as admin)

David Carlisle

@user55789 at this point I would give up here and take it (as text not as an image) to the texlive list (texlive@tug.org) where people who understand tlmgr internals (= Norbert:-) are probably more reliable than me guessing (especially as I have never used the windows texlive, even though I use texlive on windows, I always use cygwin to have a more unix-like experience:-)

user55789

@DavidCarlisle Ah I might. Thanks regardless, your effort is appreciated

@DavidCarlisle Actually, as it looks now, your command line approach may have solved the issue of updating, since it's happily updating all the packages now.

Windows works in mysterious ways...

David Carlisle

9:41 PM

@user55789 Windows works fine as long as you avoid the windows part of it (I use X windows mostly:-)
