@UlrikeFischer in the following page, I click on the "install-tl-windows.exe". A file comes to my laptop and after extracting, the package manager starts to receive all the packages. After downloading about 200 packages it stops.

@JosephWright -- Edited profile has now been updated on all stackexchange sites, but not on the network profile. I guess I'll have to update that manually, unless you know a way to trigger the update automatically. ???

@yo' -- Hi, Tom. No, probably won't change name. I've been using the monogram "bb" for longer than TeX has existed. For example, it's on a needlepoint piece I made for my mother in the early 1970s. ("BB" was already taken by Bill Blass, and I don't like to go around impersonating other existing people.)

@barbarabeeton and Brigitte Bardot :)

There's a reson for not accepting I've never thought of: tex.stackexchange.com/a/474782/101651

Now users ask me to provide a penguin. Scary. I do not have that many pullovers.

@UlrikeFischer I hope she got a really good breakfast. ;-)

@AndréC Isn't texlive better? I have never heard of ProTeXt

Quack!

@EnthusiasticEngineer I have never tried ProTeXt, but I tried MiKTeX which the former is based on. TeXLive is better, in my opinion (I have Windows). I switched to TeXLive because MiKTeX site was often down and I wasn't able to download the package I needed on-the-fly. The only flaw of TeXLive is that the first installation takes a lot of time because it downloads all the packages.

@UlrikeFischer even better than a plugin, it's a complete replacement.

@DavidCarlisle but the question is about a plugin and the OP probably can't find out to use a replacement.

@HenriMenke did you ever looked at this old bug? sourceforge.net/p/pgf/bugs/295

@UlrikeFischer I came across during my bug hunt before the last release but couldn't think of an ad-hoc solution.

@HenriMenke Well I guess ones needs a second set of nodes, and perhaps an option to tell which one wants, or an option to define an own set, relative to hoffset etc.

\documentclass{scrartcl}
\usepackage[T1]{fontenc}
\usepackage[a3,center,cross]{crop}
  \usepackage{tikz,lipsum}
   %\makeatletter\def\pgf@sys@pdf@mark@pos@pgfpageorigin{\pgfpointorigin}\makeatother


 \begin{document}

 \tikz[overlay,remember picture]\draw[green,<->] (current page.south west) --  (current     page.north east);%

\tikz[overlay,remember picture]\draw[red,<->] ([xshift=\hoffset,yshift=-\voffset]current page.south east) --  ([xshift=-\hoffset,yshift=\voffset]current     page.north west);%

@UlrikeFischer I think the situation with \voffset is actually a little weirder than it is for \hoffset.

I'm not entirely sure how or why, but it appears to be corrected for in the wrong direction (and consequently doubled).

Just a sec…

\documentclass{article}
\usepackage{showframe,lipsum,tikz}
\hoffset=4cm \voffset=4cm
\begin{document}

\tikz[remember picture, overlay]
    \draw[red] ([xshift=0pt,yshift=-2\voffset]current page.north west) circle[radius=.25];%
%%     no xshift,ok ↑↑         ↑↑ yshifted by \voffset TWICE?!?
\tikz[remember picture, overlay]
    \draw[red] ([xshift=1in+\oddsidemargin,
                 yshift=-1in-2\voffset-\topmargin-\headheight-\headsep]current page.north west)
                circle[radius=.25];%

I'm not sure what the expected behaviour is, but this should clearly not be it.

(I was attempting to place the circles in the top-left corner of the (shifted) page and of the text are and was rather surprised that \voffset needed to be applied twice.)

(It was for an answer on this site that didn't actually have a non-zero offset, but I tested it with offset to make sure I got the signs right. I should probably have filed a bug report…)

@Circumscribe you should normally better think from the south and from the (physical) paper.

@UlrikeFischer Reading it back now, I see that my statement wasn't very clear. I knew all vertical coordinates would have inverted signs when measured from the NW corner.

@UlrikeFischer What I should have said is that current page.north west is shifted by \hoffset along with everything else (which may or may not be correct, I'm not sure), but that it is shifted in the opposite direction from everything else if \voffset is set to something non-zero.

Irrespective of whether you think current page.north west should be the NW corner of the physical page or if it should be shifted along with all other output, this is clearly wrong.

Just realised I forgot to ping @HenriMenke. (And I need to leave, so I probably won't respond for a while.)

@EnthusiasticEngineer I don't know if one is better than the other. ProTeXt is based on MikTeX. There are questions about that. This one is 7 years old, are its answers still valid? I don't know. tex.stackexchange.com/q/20036/138900

@Circumscribe I know what you mean - and I agree that the output it wrong (as it is if you remove the center option from my example). But if you want to understand it, you must start at south west: the origin of the pdf is at the lower left, tikz then moves it by hoffset and voffset: \def\pgf@sys@pdf@mark@pos@pgfpageorigin{\pgfqpoint{\hoffset}{\voffset}} (which is fine with crop + center but wrong in other cases), and then calculates the rest.

@marmot @UlrikeFischer tex.stackexchange.com/questions/474841/fun-with-tikz-dogs

@CarLaTeX My answer would be: hopefully not.

@Circumscribe this patch should solve your problem too: sourceforge.net/p/pgf/bugs/295/#5ef3

@UlrikeFischer Yes, that seems to be a good explanation for what happens.

@JosephWright Did you see tex.stackexchange.com/questions/474813/…? I suspect that some changes in l3kernel triggered this.

@UlrikeFischer I've seen it but not tried it yet

@marmot dogs and marmots don't go well together

@UlrikeFischer Bisecting ...

@UlrikeFischer Tracked it down. xsim is passing an empty file name with the name in the path part of the argument. It wasn't showing due to a bug in expl3.

@JosephWright an old bug in expl3 or a new bug?

@UlrikeFischer expl3 behaviour has changed, but really this is an issue in xsim:

\tl_set:Nn \l__xsim_file_path_and_name_tl
  {
    \tl_if_blank:VF \l__xsim_file_path_tl
      { \l__xsim_file_path_tl / }
    \l__xsim_file_name_tl
  }

@JosephWright I saw this. But what is wrong with it?

I was using synctex in texworks with latexmk and latex and dvips and ps2pdf. I was surprised that synctex is off by about one line, while when I set it to use with pdflatex, it goes to the correct line. Interesting right?

If anyone else experienced this or knows the reason, let me know! Also, Happy Valentine's Day!

@UlrikeFischer It was relying on full expansion of the file name at the primitive level. We don't do that any more, so rather than look for a name it's looking for the code for a name, I think. Still tracing it through.

Today is Valentines and my computer showed me this ^^

@JouleV I see you are using WIndows 10, LOL. That's a nice picture!

\documentclass{article}

\usepackage[enable-debug]{expl3}

 \tl_set_from_file:Nnn \test {}
                {test-utf8-question-1-solution-body.tex}
\ExplSyntaxOff
\end{document}

@JosephWright this gives the same error ^^^

and it tells me that the command is deprecated, but the new command is not in the docu ;-(

@UlrikeFischer \file_get:nnN isn't there?

@JosephWright let's say the adobe search doesn't find it.

@JosephWright but I have the version from Released 2019-01-13.

@UlrikeFischer You mean if the file exists or if it doesn't?

@UlrikeFischer Ah, right, got it

@UlrikeFischer Fixed ...

@JosephWright \file_get:nnN gives the same error.

@UlrikeFischer Huh?

\documentclass{article}

@JosephWright well due to the missing docu I used the arguments in the wrong order ;-)

@UlrikeFischer Page 152

@UlrikeFischer Building for release now

@JosephWright seems to work. Do you want to post an answer or should I?

@UlrikeFischer I've posted a quick fix

@JosephWright I have copied the message to the issue at the xsim github.

@JosephWright I don't have \file_get:nnN on this page, and while the file date of interface3 and expl3-code is 01-28, it shows on the cover page 01-13. (And I checked that I really opened the version in texmf-dist).

@JosephWright but miktex has the version from 01-28, it looks as if texlive mixed up something.

@UlrikeFischer It's New: 2019-01-16 so that explains it

C:\Users\joseph\Documents\LaTeX\LaTeX3>texdoc -l interface3
 1 C:\texlive\2018\texmf-dist\doc\latex\l3kernel\interface3.pdf

@UlrikeFischer ^^^

@JosephWright hm. curious. But I guess at the next update it will sort itself.

@UlrikeFischer Should do

@UlrikeFischer I'll fix the keys issue if I can then do a release

@CarLaTeX There are already so many dogs on the street (and I got attacked by a dog at the age of 2....)

@JosephWright people poking into pain from my youth:(

@DavidCarlisle I'd seen :)

@DavidCarlisle \protected\def\textcolor ...

@JosephWright \fontspec{use color font}

@DavidCarlisle :)

@DavidCarlisle Indeed, sounds like a plan

I don't see egreg here. Is he busy?

Oh he is here.

@CarLaTeX MiKTeX now is cross-platform too and you can also use it to install all packages if you don't want to install later on. =)

@Jasper it's still not clear to me why it's cross platform (that is texlive's job) the whole reason for miktex really seemed to be that it was more naturally a windows application, if it makes the compromises needed to be cross platform then I can not see how it can really compete with texlive

@DavidCarlisle Aha! Yeah I think installing both of them are equally simple after you read some instructions. Anyway, one thing that miktex does have that texlive doesn't is texify, but that works just like latexmk.

Another thing I am not sure about miktex is the release cycle. It seems to me that one can always update all the packages and never has to reinstall.

For me I just install the annual texlive once after uninstalling the previous year's release.

So if what I said above is correct, people with different update cycle preferences could choose one over the other.

@marmot Oooh

@Jasper texify is a pain. Every week it leads to a question with the very speaking error message "something didn't succeeded". I wish it wouldn't exist.

@Jasper I haven't used it for years, now. I still prefer TeX Live because it is mantained by the TUG

I haven't used miktex for years. Maybe I should give it a try to see what differences there are now.

@CarLaTeX Everyone who has been attacked by a dog as a child has the same fate: dogs will go after you for the rest of your life.....

@marmot Do you know any reason for that?

@Jasper Subconsciously you are very scared, and dogs get attracted by that.

@marmot I am now thinking if a fearful person attracts more fear...

Some dogs can be bigger than some humans.

I was chased by a dog when I was 18 or so, and I ran away.

The dog continued to run after me, until someone bigger shouted at the dog.

@marmot Same for Windows.

If you get chased by a fierce dog, don't run away. Face it and make as much noise as you can. Same for lions.

@Jasper I do not know how dogs sense it but I know that this happens, and some expert told me the explanation, and I know others who were attacked when they were very have the same experience.

@AlanMunn Wait, I don't get that, LOL.

@Jasper I should have known that when I was 2....

If you run away from a lion you are dead.

@Jasper Yes, but there are not as many lions around as dogs where I live.

Same. Where I am, there are only lions in the zoo, LOL.

But some people do live very close to such animals in some countries.

@Jasper Early traumatic experience with Windows causes one to avoid it. Just like dogs. But I know that secretly, Windows is out to get me.

@Jasper A relative of mine has been killed by a (mountain) lion....

@Jasper Well in N. America, bears are the probably most dangerous animal people might encounter I think.

@AlanMunn I remember you use the Mac. Money aside, I was thinking of getting a Mac laptop. The problem is that all the newer Mac laptops have 2 problems: unreliable butterfly keyboard, and only USB-C ports and no other ports.

@Jasper I never use the built-in keyboard of my Mac. The second point is a very valid one, shame on Apple.

@Jasper Yes, the newest Mac model is an abomination. I've been resisting upgrading my nice MacBook Pro until they fix the problems. I think it's one of the worst Mac models ever made.

@AlanMunn The 2015 Macbook Pro and the 2017 Macbook Air are the last Apple laptops with scissor keyboard and USB-A ports.

@marmot Well, that makes it even more inconvenient if you need to use an external keyboard on a laptop with an existing keyboard.

@Jasper Well, I am born with claws, what should I do? ;-)

@marmot LOL. I only knew what a marmot is 5 min ago when I saw the website.

@Jasper OMG!!!

I don't think marmot is a common word in everyone's vocabulary.

@Jasper What?! ;-)

Maybe it's just me. I use very few words. =)

Anyway, I don't know why Texmaker is still called Texmaker and not TeXmaker. =)

But it is one of the better editors out there.

I am not sure how TeXstudio is different from it.

@AlanMunn Prices are also going up up up.

@Jasper Yes, that's true, but I'm fortunate in not having to buy my own.

@marmot I have always had a dog till few years ago, I love dogs, I'm scared only by the more aggresive ones

@CarLaTeX Yes, sure, I understand that there is a distinction between responsible and careless owners. But after a while you get sick of "Please control your dog" "(S)he's friendly" "OK, and these are the bite marks." "This is the first time." "SIGH." I got repeatedly attacked by dogs and wish they would be under better control.

@Jasper I'm not sure. I see a lot questions about problems with it in the last time, there is not sensible issue tracker, and the disclaimer on the web site below the contact info is rather curious.

@marmot Oooh

@AlanMunn I think hornets and bees kill more people, but only because they are encountered more often than bears. (And most black bears are apparently not too likely to attack, so long as you don't surprise them. Brown bears and grizzlies are another story.)

@HaraldHanche-Olsen Yes, that's probably true. But bears are more analogous to lions. And it's true that with black bears you mainly need to worry about keeping your food out of their reach rather than physical attack. I haven't done any backpacking in the west, so I only have experience with black bears.

@AlanMunn At the Aspen Center for Physics there is a basket with flashlights that you are supposed to take with you if you leave the center after dawn: to make sure that you do surprise and thus scare them.

@marmot The ones with most contact with humans are usually the most dangerous.

@AlanMunn There they aren't AFAIK. Incidents are very rare. (I've seen several of them from a very small distance and was not scared at all, and of course everything was fine.)

@John Kormylo done!!

@Raaja As for the closure of this post. I certainly do not disagree with this post being closed. However, I am wondering if "unclear what you're asking" is the appropriate reason here, IMHO it is pretty clear what is asked. One should perhaps allow for a new reason for closure like "insufficient efforts by the OP" or something like that.

nobody helps me :(

@EnthusiasticEngineer who's nobody?

@Skillmon TeX, LaTeX and Friends

@EnthusiasticEngineer and what is your problem? Did you ask a question on the main site?

The question is asked on the website by a user.

But the solutions do not really work.

I can not install TeXLive on my laptop

@EnthusiasticEngineer link?

@EnthusiasticEngineer why not? Which message do you get?

there are questions like this on site

the solutions are not helpful indeed

I asked my question in this room also:

@EnthusiasticEngineer you could try to load the complete iso and then install from that.

@EnthusiasticEngineer change mirrors to something closer to your location.

@EnthusiasticEngineer check free disk space whether it is sufficient.

I have recently clear installed my OS

lots of free space

not tried loading iso, though

@EnthusiasticEngineer my TL2018 needs 7.1G space.

I have that much space

@EnthusiasticEngineer try another connection to the internet if possible (LAN, different network, etc)

is it possible to download all the packages in an iso file?

@EnthusiasticEngineer did you run the executable with privileges or without?

@EnthusiasticEngineer it was at least, I'll quicksearch.

@Skillmon I gave admin access to the exe installation file

it seems this is a bug

I deactivated my virus scanner while tried to install texlive

as the program prompted when it opened

@EnthusiasticEngineer did you try to run the .bat as admin?

not bat, .exe file as admin

@EnthusiasticEngineer did you have a look at tug.org/texlive/windows.html ?

@EnthusiasticEngineer options to acquire TeXLive: tug.org/texlive/acquire.html

@EnthusiasticEngineer iso is part of those options.

tug.org/texlive/acquire-netinstall.html

I downloaded exe file from this page

@EnthusiasticEngineer I will leave now. Good luck in installing it. If you don't succeed, ask a question on the main site, stating what you've tried so far.

@Skillmon thank you, by the way

@marmot Here though I am on the side for closing the post, I would agree with you on your remark regarding the insufficient info by the OP. However, I also voted to close that post for "unclear what you are asking", because, in the past, I have witnessed similar posts closed for the very same reasoning. However, from now I will take your remark into account and whenever such an instance happens, I will ensure that I will do all I can from my end :)

but the way did u plan reaching 100k today ;)?

@Raaja I was not meaning to criticize the decision to close the post. My confusion is more that there seems to be a broad agreement that "insufficient efforts by the OP" are a valid reason to close a post. On the other hand, when closing the post, there is no way one can choose this option. This may either mean that we are not supposed to close a post for that reason or that we have to add this option to the menu. What do you think?

@Raaja No. Such things cannot be planned and are not important (except that in the range from 100K to 1M there are no paliprimes ;-).

imo rather than having such a singular option, my proposal would be to have a comment box (similar to the one where there is a comment option for the first close voter: I vote to close because...).

@Raaja Too bad, I thought today is a nice day to reach 100k ;) ok, lets settle that it is a(n un) planned coincidence ;)

@marmot I do understand that part of non-criticizing remark ;-)

I will order my Falcons not to hunt any @marmot's today

:D

@Raaja I wanted to say that I feel that there are very good reasons to close such posts but "unclear what you are asking" may not be one of them. "Not criticizing" just means that I know that this is common practice. I was more wondering if there was a way to make it more transparent to the OP why their question was closed.

@Raaja Most of my fellow marmots are hibernating several feet below the surface, I guess the falcons won't be catching many today in any case.

@marmot if you discount the points from tikz answers (that obviously don't really count) I suppose you will stay in paliprime range for some time?

@DavidCarlisle Yes, there is a long range above 1M, which is what you are probably referring to, right?

@marmot I was thinking of the range including primes like 2 and 5

@DavidCarlisle I believe that the number of primes only composed of 2's and 5's in the range above 10 is zero.

@marmot I think it's best to stick to even primes.

@DavidCarlisle 490,132 is even but I am afraid not prime.

@marmot keep looking, you may find one.

@DavidCarlisle Just found one but will keep it secret. ;-)

@DavidCarlisle Are you involved in overleaf? overleaf.com/learn/latex/Picture_environment ;-)

@marmot no, but you would expect them to tell people about the important environments. LaTeX isn't just about mathematics, people use it for aircraft design and drawing animals.

@DavidCarlisle ... and beings!

@CarLaTeX I really feel that the answer to your question may be as simple as "look at the manual of your current LaTeX installation". Then there is a related question of how to access the manual of a package on overleaf, which is IMHO an independent question (and may not even fall in the scope of our main site).

@marmot Also "tell the author to put a version in the code"

@CarLaTeX Well, the author did put a version in the manual. And even if he added the version now, this wouldn't help when using an older version.

@marmot That's true

Does someone know how to reply? ^^^

Happy Valentine's Day to all lovers.

@CarLaTeX If I am not mistaken, the version information is provided by by pgfrcs.code.tex and pgf.revision.tex. However, @HenriMenke will be a much more reliable source of information.

@marmot @PhelypeOleinik already found a good solution

@UlrikeFischer Ah, I hadn't realised a cropped and centred logical page was assumed.

@UlrikeFischer It does, that's much better!

@CarLaTeX I saw (and upvoted) it. I thought your question was more on how to apply the version system of the "ordinary" tikzlibraries to libraries by authors that are not maintainers of TikZ.

@Circumscribe @UlrikeFischer had help from a new member of the household, I suppose. ;-)

@CarLaTeX Glad you liked :)

@PhelypeOleinik Very good, thank you!

@marmot Of course, marmots know a lot about pgf/TikZ after all :).

@marmot Yes, too, but the specific problem was on tikzmark

@marmot The LaTeX-Bär was a bit grumpy that someone suggests, that he can't do this too, but I explained him that it is okay to delegate this to the tikz-marmot - he can take care of picture mode.

@UlrikeFischer Why isn't the Bär hibernating? ;-)

Hello guys!!

I want to make a T-shirt of a duckling!!

I want to know which duck would be the best to show to any person!

I think about the duck of my profile picture, do you like it?

(Btw, @samcarter I am going crazy to find a post where the code for the duckling is shared with the logo of the Argentine flag, do you know where I can find it?)

@manooooh Any person? That's asking a lot. Your pato argentino is very cute, but maybe Brazilians won't like it (except @PauloCereda who is crazy for any kind of duck.

@AlanMunn hahaha

We have to spread the duck-word

@manooooh I usually try to duck the issue.

@AlanMunn oi

@AlanMunn ooh

@manooooh You may need to wait a few weeks for a response from @samcarter.

@PauloCereda It doesn't take much to change an oi to an ooh. :)

@AlanMunn nope :)

@manooooh That's a so-called oxymoron. From the description one may think you are looking for a marmot. ;-)

@marmot uhmm, no, sorry, I am looking for a duck T-shirt ;)

(Oops, linked to the wrong post, but I'm sure it was clear which one I was responding to.)

@manooooh Well, if you really want to make sure that everyone likes it, better depict honey liquor.

@marmot LOL

@samcarter I found the post: tex.meta.stackexchange.com/questions/7529/…

Unfortunately I cannot figure out how to insert the flag (I want a better resolution for the duck)

@manooooh don't you have the tikz source?

@DavidCarlisle no, samcarter shares the image, not the code

Btw hi David!

I remember that I saw a post where all the ducks-with-a-flag were shown, but unfortunately I cannot remember where I read it :(

I am looking at tikzducks tag

@manooooh there is a small edge at the collar, imho the flag is simply a picture.

@manooooh It is straightforward to add the blue-white-blue stripes to the duck, but the there is the "broke" sign in the flag which might be more delicate.

@UlrikeFischer oh, thank you for pointing it out! What type of duck would you suggest?

@marmot uhm

I swear to God I had seen a post with many ducks with flags

The only duck in the tikzduck package that is usable is this one github.com/samcarter/tikzducks/commit/…

@DavidCarlisle oh

That edit saves the meaning of the sentence :P

I will look at the source

@marmot -- Sometimes even very friendly dogs are a surprise. My esperience was when I was hiking the Appalachian Trail with my girl scout troop. I was in the middle of the group, and a very friendly Chesapeake Bay retriever bounded up the trail to visit us, right past the girls in the front, raised up and put his paws on my shoulders and gave my face a great big slurp. No bites, and I wasn't scared, but I certainbly was surprised!

@manooooh A number of flags can be found at tex.stackexchange.com/q/438098/121799, unfortunately only nations who are good at soccer made it there, so no Argentinian flag, sorry. ;-)

@marmot LOL, shhhh, we are the best soccer team of the entire world!

@barbarabeeton Yes, I can see that many enjoy the company of dogs. But honestly I am concerned that dogs are now allowed pretty much everywhere, even on planes, which complicates the life of those who are allergic to their hair. And I doubt that therapy dogs are less a concern for hygiene but they are still allowed on the Farmers market (while "ordinary" dogs are not for hygiene reasons).

@manooooh simply search for "flag argentina vector", somewhere there will be something usable ...

@DavidCarlisle I do not know what that code is for

@UlrikeFischer ok, I will search. Big thanks <3

Talking to myself: now I can see why @jfbu got "disappointed".

@marmot what happened?

@manooooh samcarter would like to share github.com/samcarter/tikzducks/blob/master/duckpond/… and github.com/samcarter/tikzducks/blob/master/duckpond/… with you. (You see, even without soccer you can get a flag.;-)

@UlrikeFischer Got criticized for not fixing something not at all relevant to the question in an answer by two users in a row.

@marmot OMG <3 <3

@samcarter thank you so much!! I have a GitHub account, how can I give you "Thanks" (or maybe post a thank you comment)?

@manooooh I see, this sign represents the sun, and is not a "broke" sign. Learned something. ;-)

I already had the image of Argentina, I just needed to know how to place an image on the using stripes parameter

@marmot haha. Did she just post it on GitHub?

@manooooh Dunno.

@DavidCarlisle Could that be a bug in longtable?

@marmot it says 14 minutes ago so I think so. Why did not she write it here first to let me know?

@manooooh Psshhht!

@marmot xD

@Kurt Have you ever had a look at the source of revtex4? ;-) ;-)

@samcarter let me know how I can thank you

@marmot no, should I have? Seems better not to have a look ...

@Kurt I'll look but I suspect its a feature of the revtex enhancements

@Kurt But David Carlisle is a very common name so this may not mean anything. ;-)

@marmot It could be this person:

rossandyerger.com/index.php/team/producer/david-w.-carlisle

@marmot poor @DavidCarlisle, nearly everybody is blaming him. I feel with you, David!

@Kurt I am honestly not blaming him.

@marmot do not missunderstand me. should be a joke!

@Kurt OK, got it! ;-)

@DavidCarlisle @Kurt I feel like a child, I need you to explain me each thing so as not to fall into bad thoughts :(

@marmot the edef discussion? Don't worry, discussion about expansion details are always like that - every details has to be right.

@UlrikeFischer Also unrelated ones? (My feeling is more that I dared to enter the territory claimed by others and thus get very nice comments....)

@marmot I don't think the comments were too bad (actually in similar cases I've sometimes just edited the code in the answer rather than commenting) getting white space wrong in definitions is the most common error and so while it's expected that code fragments in questions have white space issues, it's generally better to fix them in answers as people expect code in answers to be Ok to cut and paste into a document.

@DavidCarlisle OK, fine. Maybe I was reading too much into it.

@marmot anyway you have to let egreg comment on white space issues, it's the one thing he knows about.

@DavidCarlisle ;-)

@DavidCarlisle I'm afraid I agree. ;-)

@egreg and agree with the following comment?

@DavidCarlisle Not really.

@egreg oh

@marmot People don't always discuss what is relevant but what is important for them - if you ever put a chess position in an answer I will probably moan that the position is illegal ...

@UlrikeFischer OK, fine. (But do not expect me to fix all the mathematical or physical mistakes in answers, OK? ;-)

@marmot didn't you once discuss some physical content in a image of a question?

@samcarter (and others) maybe this?:
