@DavidCarlisle -- no more or less, actually, than i've been expecting. really, to let us do our job effectively, since we've been bequeathed this mess by the se management, i feel strongly that they should at least help us identify the bogus entries that they so generously created. you've provided a reasonable search pattern that mere users can't apply, but they can. i'm very unhappy with their lack of attention to our plight.
i know we're a small community, but a genuine web-wide resource, and i think that does deserve some consideration.

@barbarabeeton yes probably true, probably it was just too late at night to be presented with a list that long for a single tag:-) I'll probably do some more later.

A: Can I show two sides of a card in one photo?

Loren PechtelWell, you asked for creative, you didn't say practical: Gravitational lensing. Place the card edge on and behind a sufficiently massive body. Position the card and camera correctly and both faces will be visible, albeit substantially redshifted, one side worse than the other. Obtaining the su...

 
8:56 AM
@DavidCarlisle, @egreg Did the 'invite' turn up? Hard for me to be sure it all works ...
 
@JosephWright yes, and an updated one
 
@DavidCarlisle Ah, good
@DavidCarlisle Sorry about the update: I have to edit back the Hangout name every time ...
 
@JosephWright you correctly predicted I'd pick up votes on old answers:
:-)
 
@DavidCarlisle :)
 
9:36 AM
@JosephWright Yes, I got both.
 
Fun mwe of the day:
\documentclass[reqno]{amsart}
\usepackage{empheq}
\usepackage[left=2cm,right=2cm,paperwidth=150cm,showframe]{geometry}
\begin{document}
\begin{empheq}{equation}
equation
\end{empheq}
\end{document}
Interesting that I need a paper width of 150cm to see where the eq no actually went. A box has the wrong size somewhere.
 
@egreg Great: unless/until some accepts I don't know it's worked! (We've only tried this once before ...)
 
9:52 AM
@daleif I think something similar has come up before... (actually wasn't it you asking about something related here the other day:-)
 
@DavidCarlisle I'm still trying to figure out what is wrong with it. Still haven't found it. But now I know the eqnos does not just disappear in thin air. There is just a box that ends up with the wrong size in a certain special case.
 
Finally I got a real blackboard in my office: 2.5 meters wide!
 
@TeXnician Thanks for the answer.
@TeXnician I am offline now (bought a new used car and have to go to the officials).
 
10:09 AM
@egreg Oooh
@egreg Picture?
 
@egreg Oh my!

@egreg Wow! Beautiful!
Knuth is also in the photo. :)
 
@PauloCereda They confirmed the slate comes from near Lavagna (near Genoa), so this is a real lavagna. This is the term we use for blackboard, because slate is also known as “pietra di Lavagna” and all blackboards used to be made with slate.
@PauloCereda I should have decorated it with the Palmeiras scarf.
 
@egreg Where or should I say when am I? Today we are using interactive whiteboards :-)
 
10:17 AM
@egreg awesome! My uncle is a carpenter and told me how they produced blackboards thirty years ago. Contrary to popular belief, this is a very detailed work.
@egreg Yay! And a Juve one. :)
@MarcoDaniel Hi Marco! Long time no see, pal!
 
@MarcoDaniel For lectures I use an iPad.
 
yo'
@egreg beautiful! I've got a similar sized one at home :)
 
@yo' o.O
 
@yo' The main working tool for a mathematician
 
@egreg I could draw lots of ducks in it. :)
 
10:20 AM
@PauloCereda I am on vacation. My current life consists of Building a house, starting a new job and playing with my child
 
@MarcoDaniel Oh it's great to have you back, pal! We were getting a bit worried with you, no news in the latest months...
@Marco: how's your little package maintainer? :)
 
@PauloCereda He's well. When I am working with my Mac, he wants to use my keyboard. So some comments are written in baby language
 
@MarcoDaniel that's great! Surely it's more readable than xii.tex :)
 
@PauloCereda :-)
 
@MarcoDaniel Just don't mention arara 4. The manual writing is stuck due to some PhD activities... :(
 
10:28 AM
@PauloCereda That's hard. How is it with your PhD?
Are you in time?
 
@MarcoDaniel Yes, I am on schedule. But the writing process takes me a lot of time and effort. Hopefully, I will have spare time soon. :)
@MarcoDaniel: Nicola has an entire book based on arara 4.0, that's great for us!
 
yo'
@PauloCereda of course, I like to work from home, my brain is sometimes active at night etc....
 
@PauloCereda As always in life: After closing a project a new project starts where you need more time.
 
@yo' Same here. Creative process is definitely not in a linear fashion. :)
@MarcoDaniel Indeed.
 
@PauloCereda Great. Nicola will be the ambassador of arara :-)
 
yo'
10:34 AM
@PauloCereda you can't order your brain to be creative at a specific moment :)
 
@MarcoDaniel Indeed. :)
@MarcoDaniel: vimeo.com/144052535
 
yo'
@PauloCereda been there done that pal!
 
@yo' <3
 
@PauloCereda oi
 
@DavidCarlisle <3
 
10:40 AM
@PauloCereda It's amazing seeing what happened in the last years.
 
@MarcoDaniel it is! A lot of improvements.
@MarcoDaniel: and you are the culprit for this.
 
 
1 hour later…
12:02 PM
@JosephWright Unfortunately, I cannot accept the invitation from the interface, because of different addresses.
 
@egreg Ah
 
12:14 PM
@egreg Next time I should send to GMail?
 
@JosephWright If you don't want to bother adding the confirmation by hand
 
@egreg Noted (somehow I seem to be the team secretary ...)
 
@JosephWright /all raise for the UK-TUG secretary
 
@PauloCereda Oh please don't!
 
@JosephWright <3
@JosephWright: cannot wait to visit you all in UK someday.
 
12:21 PM
@PauloCereda you would have really liked the UK this morning, sunny, clear blue skies, not a cloud in sight
and 1C
 
@DavidCarlisle Was very pleasant, yes
 
@DavidCarlisle brrrrrrrr
@JosephWright pleasant?!
@DavidCarlisle I like the use of sunny
 
@PauloCereda Not sure what you mean: it was (and indeed still is) sunny here
 
@JosephWright In here, sunny is a synonym of hot.
 
@PauloCereda Ah
 
12:26 PM
@JosephWright When one says it's sunny, we already understand it's hot. :)
 
@PauloCereda In UK English we separate out the temperature from the atmospheric conditions: I suspect the same is true in US English but @barbarabeeton will know
 
@JosephWright That's what brought me down when I went to Spain.
@JosephWright: ^^ Ensolarado = sunny
 
@PauloCereda Warm and sunny!
 
@JosephWright Yes! :)
 
12:28 PM
@JosephWright that would be quite cold for our standards.
 
12:47 PM
@egreg -- wow!!!! i'm impressed! even if it is in two pieces. must weigh a ton (or the equivalent in kilos; an exaggeration, actually, but i don't think i could lift it). all it lacks is a chalk tray. someone should give you a big box of multicolored chalk as a "blackboard-warming" present.
 
@barbarabeeton ooh I love the present!
 
@JosephWright -- yes, "sunny" is not equated with temperature, although on a day when there is snow on the ground, the sun on one's face feels good. (but be sure to wear sunglasses and good sunscreen -- one could go blind from the glare, and sunburn is never fun.)
 
@barbarabeeton Cool: a general English thing then (I guess in both the US and UK the weather conditions mean 'sunny' can go with 'cold')
 
@JosephWright -- that prognostication looks terribly uniform. around here, it's been bouncing back and forth between -10 and +18. the poor daffodils are very confused.
 
1:05 PM
@barbarabeeton There is a chalk tray on the far side. The two guys who installed it said it is about 70 kg (150 pounds).
 
I escaped from Italy! :-) Lost my flight yesterday since Italien air traffic control was on strike.
Time to go to the DANTE meeting in Zeuthen/Berlin.
After waiting for washing mashine and tumble dryer :-D
 
@StefanKottwitz We wanted to keep you with us!
 
@egreg Yes, I got handcuffs promised, and they wanted to duck-tape me
I mean, the people who I worked with
I let them 30 pages of TeX made documentation and my colleague as a hostage to come out of this
Cruise ship of 19 decks 1,083 feet long 143,700 tons to finish, it sails in 10 days, tons of work, but I need to go to DANTE first >:-)
 
yo'
1:37 PM
@StefanKottwitz our department guest arrived at 3:30 at night instead of 8pm
 
2:28 PM
WE NEED MORE NOISE
 
@yo' ooh
 
 
2 hours later…
4:31 PM
Stupid travel insurance...
 
@PauloCereda Regex help needed: I have a bunch of words with a \foo suffix e.g. This is a sentence\foo and a word\foo etc. and I want to match just the word and the suffix. Using \b(.*?)\\foo grabs too much before the \foo.
 
@AlanMunn ooh hold the phone
@AlanMunn Does this work? \b(\w+)\\foo
 
@PauloCereda Thanks, yes that works. I thought I had tried that, but I see I forgot the +.
 
@AlanMunn phew! You know, solving a problem with regex might cause another problem. :)
 
@PauloCereda I copied some text from another document, but the macro definition I used in the new document was different than the old one, and much hilarity ensued: so word\foo word ended up being rendered as word^1w ord instead of word^1 word. :)
 
4:42 PM
@AlanMunn uh-oh! :)
 
@PauloCereda Yes, but thanks to my deep knowledge of the Chomsky hierarchy, I know what problems can be solved with regex. :)
@PauloCereda Still not quite sure about P = NP though. ;-)

@AlanMunn Bless your soul. <3
@AlanMunn That's easy: N = 1. :)
 
@PauloCereda Here a suggestion based on your video github.com/cereda/arara/tree/rulesuggestion
@PauloCereda P=0 :-)
 
@MarcoDaniel Thanks. It doesn't make any practical difference, I guess, apart from the first of running just one rm for all files instead of a rm for each file. To be honest, I'd favour one for all, but that's just me... :)
@MarcoDaniel oh no! :)
 
@PauloCereda For me it was an aesthetic reason. One rule -- On line in terminal ;-)
 
4:53 PM
@MarcoDaniel Understood. :) But look how beautiful is our new output! :D :D
@MarcoDaniel: I will poke @Nicola, she is our official manager. :)
 
5:24 PM
Anybody up for splitting up the template tag to have an additional beamer-template tag?
@JosephWright Maybe one for meta? ^^^
 
@egreg, @CarLaTeX: is this song known in Italy? youtube.com/watch?v=9v7DQV7uFek
^^ I meant the first song. :)
 
@PauloCereda :-)
 
5:40 PM
@MarcoDaniel Nicola is the next in sucession, it seems. :) She did a wonderful job! Check her book: dickimaw-books.com/latex/admin arara4.0 heavy usage. :)
 
@PauloCereda Congratulation -- arara is the only tool which is directly named in the table of contents.
 
@MarcoDaniel I told you: you sparked the flame. :)
 
5:57 PM
@PauloCereda Never heard.
 
@egreg oh interesting... :)
 
6:08 PM
@PauloCereda Never heard, the only Toquinho's song I know is "la ragazza di Ipanema"...
 
@CarLaTeX Ah!
 
:36
 
BFH
Hey. Does anyone know how to make a global command with multiple required arguments and multiple optional arguments? The complexity is overwhelming me.
 
6:24 PM
@BFH What do you mean with "global"? I think you looking for the package xparse
 
BFH
\newcommand*{\command}[1]{\gdef\@program{#1}%
}
except with multiple arguments
sorry: \newcommand*{\commandname}[1]{\gdef\@commandname{#1}%
}
it would be called like this:
\commandname{foo}{bar}{baz}
xparse confuses me mightily
 
@BFH What should this do?
 
BFH
@egreg I'm writing a command that makes an approvals page and lists 3 to 5 names below a form, and has signature lines for two names. Each name has at least one comma in it for the titles of each individual
It's a mess right now and I want to simplify it
 
@BFH sounds like you want a comma separated list rather than varying number of arguments
 
BFH
needs to be semicolon separated
which I couldn't figure out either
 
6:32 PM
@BFH whatever, same thing:-)
 
@BFH Please, make a proper question on the site, specifying what you want to accomplish.
 
BFH
OK. Since it's currently working but janky, I will put up what I have now as an mwe.
 
6:46 PM
@PauloCereda For my next letter I will use the rule velocity ;-)
 
@BFH You see, it mostly depends on how you want to use the command.
 
@MarcoDaniel Oh no! :)
 
7:02 PM
@JosephWright Few minutes ago I found the following question: tex.stackexchange.com/questions/243848/… -- I suggest using \cs_new:Npn instead of \def github.com/latex3/latex3/blob/…

Q: Variable inputs for global command

BFHI'm developing a template and I have a janky but working way of making the approvals page: I define various macros in the main document: \newcommand{\advisor}{Name, Degrees} %uncomment the following line to add a second advisor %\newcommand{\advisortwo}{Name, Degrees} \newcommand{\dean}{Name,...

 
BFH
@MarcoDaniel I'm aware that it's too specific to my use-case but I have no idea how to minimize it further. I already took out a lot of things that weren't relevant.
 
@BFH But minimally you need to make a compilable document, not post fragments of code, which is what you've done.
 
BFH
@AlanMunn It's difficult because there are multiple files. I'll give it a shot.
 
7:43 PM
@egreg: In your answer tex.stackexchange.com/a/348057/5239 you should change \foo[\textbf]{a,b;c} to \foo{a,b;c}[\textbf] (Or you can change the definition of \foo ;-)
in your second code example

Q: Slow fontspec with xelatex

igm2103I have been using XeTeX 3.14159265-2.6-0.99992 (TeX Live 2015/W32TeX) with fontspec 2015/03/14 v2.4c and recently I have also installed MiKTeX-XeTeX 2.9.6216 with fontspec 2017/01/02 v2.5c. This slowed down things considerably. As suggested in other posts I have tried to cache the fonts by runnin...

 
9:09 PM
@DavidCarlisle I added a comment but can't say much about it.
 
@UlrikeFischer thanks
 
@DavidCarlisle: I managed to get a "PANIC: unprotected error in call to Lua API (object in use)" with lualatex and then a crash ;-(
 
@UlrikeFischer I've had those too! Blame @egreg.
 
9:37 PM
@UlrikeFischer “Don't panic!”
 
@egreg well knock me down with a feather, an L3 list processing answer arrived to that title page question.
 
10:12 PM
@DavidCarlisle With some reasons to.
@MarcoDaniel Thanks
 
@JosephWright: I found in bug in your biblatex-style IEEE tex.stackexchange.com/questions/359685/…
Correct is: I found a bug
