Paul Gessler

@PauloCereda bingo! 100% correct!

Paulo Cereda

@PaulGessler: where were you? :(

@PaulGessler Yay! :)

Paul Gessler

@PauloCereda depending on when this was taken I was either sleeping or working in my hotel room, lol.

Paulo Cereda

Either @Arthur is really tall, or Will is... well... quite short. :)

@PaulGessler ooh :)

@Paulo It's a mix of both, really :-) Joseph is actually taller than me.

Johannes_B

@PauloCereda Nothing to explain, just don't, don't. Oh please don't watch that.

@ArthurReutenauer Joseph looks quite tall indeed. :)

@Johannes_B ooh

:)

Harish Kumar

@PauloCereda Oh oh!. That is good. :) Thank you. Now I see some very young lads and some elderly men ;)

I noticed that we always tell poster to provide a MWE. But many folks who answer, actually just give one or 2 lines answer, even the experts, and do not show a MWE in the answer, and not show the output (where appropriate). Should not the answer also be self contained just like the question? Many times I have hard time with these answers and how to use them since they are just small fragment and missing much code.

Paulo Cereda

@HarishKumar :)

Harish Kumar

00:39

Bruno, Henry, Joseph all look very young :)

@Nasser Many of us do try to give MWE answers with images as well. But some questions are so simply answered with a line or two of code, it's not always worth the effort. I guess if you have questions about an answer you could leave a comment asking for clarification.

Q: amsbook customization of toc, section alignments and running heads

I am working with \documentclass[12pt,twoside,openright]{amsbook} and I wish: titles of Chapters centered in the page titles of Sections left aligned (for instance: 3. Third Section) In the contents, the full titles of the Sections and, since such titles are sometimes long, the running heads...

@egreg or someone else familiar with amsbook ^^^^^. i've left a comment on this how it's best done, but i can't do anything about it until i get back to the office in august, so someone else please give this person a workable answer.

@PauloCereda Wrong combinations of genes, that's the best explanation ;-)

Johannes_B

it seems that with KOMA v. 3.20 fancyhdr will not work anymore. I wonder how many documents will break.

Christian Hupfer

@Johannes_B: The solution: Don't use KOMA :-P

Johannes_B

@ChristianHupfer Support is a bit easier for KOMA classes. I don't need to patch stuff all the time and explain it. The amount of patching \@chapterhead on site is just ridiculous.

Christian Hupfer

@Johannes_B: Yes, but I don't like KOMA anymore. It's too much overhead for me ... I will use the summer holidays and remove scr.... stuff from my work sheet etc. files

Johannes_B

@ChristianHupfer Ok.

Christian Hupfer

@DavidCarlisle and @JosephWright: One for you tex.stackexchange.com/questions/256807/…

David Carlisle

10:30

@ChristianHupfer think comments are right that prop is essentially a sparse array, but for dense arrays with numeric index we don't currently have code.

Christian Hupfer

@DavidCarlisle You're the expert... I have not used l3 very much so far. Perhaps you should comment or answer there

David Carlisle

@Nasser it depends on the answer and the time available. people choose to ask and should take the time to ask an understandable question. if I only have a minute to spare it may be more useful to give a one line answer than no answer at all.

@ChristianHupfer did you see @JosephWright svn stats he posted yesterday:-)

@ChristianHupfer almost all my l3 use is from before we did latex2e....

Christian Hupfer

@DavidCarlisle: No, I didn't. Should I have seen it?

@DavidCarlisle Ah, that's where the bugs entered in l3 :-P

David Carlisle

@ChristianHupfer in general no, but if you think I know lots about l3 then perhaps yes;-)

14 hours ago, by Joseph Wright

@DavidCarlisle For fun, I checked through all of the LaTeX3 SVN:

Christian Hupfer

@DavidCarlisle You're just about destroying my idolizing image of you being a LaTeX(3) hero , you know?

Dominic Michaelis

10:50

Hi

David Carlisle

@ChristianHupfer excellent, it's all going to plan then!

@DominicMichaelis hi

Christian Hupfer

@DavidCarlisle :D

@DominicMichaelis New user? Hello from me too...

Dominic Michaelis

@ChristianHupfer Not really but a very inexperienced one

Christian Hupfer

@DominicMichaelis Ah, ok, never noticed you so far ;-) But I cut down my chat time a little bit, perhaps that's the reason

@DominicMichaelis: Inexperience is quite relative, I would say ;-)

Dominic Michaelis

at the moment I need to replace a lot of number ... unit by \Si{number}{unit} and i think it would be much easier if I know something about regular expressions :D

David Carlisle

11:00

@ChristianHupfer there are people here with some years more experience than me, I've only been using latex since 1987.

@DominicMichaelis the regex syntax is easy enough once you get used to it, the hard part is deciding what exactly is the rule you need to distinguish the numbers to be wrapped in \Si from other numbers such as dates etc (or you use a simpler regex that does not distinguish and use an editor that lets you say yes/no in each case, rather than sed or perl just changing all the files in one go)

Christian Hupfer

@DavidCarlisle ...which is ten years more than I am using it. I think, one of the first packages I used was graphicx... I always wished to talk to the author of that package, but I can't remember his name.. Do you him, by chance? ;-)

David Carlisle

@ChristianHupfer no idea

Dominic Michaelis

@DavidCarlisle the document has fairly no other numbers in it

David Carlisle

@DominicMichaelis are you on unix ? (so have sed or perl or something) or windows?

Dominic Michaelis

I have windows, but winedt search function allows regular expressions

the replace function too

David Carlisle

11:10

@DominicMichaelis ok syntax varies from system to system but basically you want to replace ([0-9.]+) *cm by \\Si{\1}{cm} that is match a run or digits and decimal pint followed by any amount of space followed by cm by \Si with the contents of the first () group in the first argument. some regex systems use \1 some use $1 to refer to the () groups. I don't know winedt but ideas are always the same

@DominicMichaelis if getting brave you could replace cm in the match by (cm|m|Kg) or whatever and replace cm in the replace by \2 so it does all units at once, but I'd do them one at a time, as a check:-)

Dominic Michaelis

oki thanks :)

David Carlisle

@DominicMichaelis and if it all goes wrong and messes up your file, blame @ChristianHupfer

Christian Hupfer

@DavidCarlisle Or @PaulGessler ... or @egreg

Dominic Michaelis

11:42

ah i think now i got it, i have to search for " {+[0-9\,]}2

without the 2, and replace it by \\SI\{{+[0-9\,]}\}

hhh

11:55

What is so special in this expression that compiler does not stop?

$a\Rightarrow b\iff a\and\neg b$

Just trying to write proposional logic and got into some loop, why?

Solved!

It is \land, not \and

Dominic Michaelis

i got a lot of overfull boxes which are all exactly 12,0 pt too wide from using \multicolumn{2}{p{\linewidth}}

what would be a better width?

Torbjørn T.

12:10

@DominicMichaelis \dimexpr\linewidth-2\tabcolsep

Dominic Michaelis

ah thanks :)

Paulo Cereda

Is function composition really denoted with f \circ g? Oh my.

Dominic Michaelis

@PauloCereda yes how else?

Paulo Cereda

@DominicMichaelis Just thought it could have other symbol rather than simply \circ. :)

daleif

@egreg feature request for kantlipsum: Provide a few shorter texts. This will be useful for testing constructions that are only expected to contain smaller amounts of text.

David Carlisle

12:23

@PauloCereda the other common symbol is juxtaposition but that can get confusing:-)

Paulo Cereda

@DavidCarlisle Indeed. :)

David Carlisle

@hhh I'd have expected a simple undefined error for \and (\or is usually the problem as that is a tex primitive)

@PauloCereda are you writing function application on the right? please do!

Paulo Cereda

@DavidCarlisle: would it be evil if we add a legend to the blog photo based on Monty Python's Spot the looney sketch? :)

2

David Carlisle

x f g = x (f ∘ g) so much more logical

Paulo Cereda

@DavidCarlisle I'm going with lambdas. :)

David Carlisle

12:28

@PauloCereda not evil, but a bit rude to egreg don't you think?

Christian Hupfer

@PauloCereda: Too easy: All of them are looneys :-P

Paulo Cereda

@DavidCarlisle that's mean. :)

@ChristianHupfer :)

Dominic Michaelis

@DavidCarlisle why ? if you have linear mappings A,B (i will denote the induced matrices with A and B as well you have) (A\circ B)x= A\cdot B \cdot x

David Carlisle

@DominicMichaelis but that's cheating:-) in that you choose to write the matrices that way (rather than transpose) so left multiplication works, but for general function application you don't have that luxury. When I did algebra as 1st year undergrad the professor made a point of always writing functions on the right (partly to get rid of half the students before Christmas I think:-)

Q: Beamer interaction remove footline

Can anyone explain why the MWE below is bad? When I compile it, there is no footline on the first page!?! I use the <+> and <+-> in order to not having to explicitly having to specify the various overlays. \documentclass{beamer} \usepackage[T1]{fontenc} \usepackage{fix-cm} \usetheme{Copenhagen}...

beamer

It find it strange that this combination can remove the footline.

Paul Gessler

13:39

@ChristianHupfer what did I do now? ;-p

Paulo Cereda

Just read about this new monospace font: github.com/larsenwork/monoid

Johannes_B

@daleif I have been meaning to do that request for the blindtext package. :-)

daleif

14:07

@Johannes_B I just often see myswelf going into the sources (shortcut in my editor) to take just a piece to use as sample code.

Johannes_B

@daleif For a caption where just two sentences are needed, i usually make up some strange sentence :-)

Joseph Wright

@DavidCarlisle I think I've tracked down Morten on Github :-)

Christian Hupfer

@PaulGessler I know what you did last summer :-P

Joseph Wright

Interesting blog stats: I get more hits on my own one than the TeX-sx one gets

David Carlisle

@JosephWright on my blog I've enough hits to (virtually) earn £34.36 :-)

Paulo Cereda

14:56

@DavidCarlisle ooh money

David Carlisle

@PauloCereda define "money"

Paulo Cereda

@DavidCarlisle paper thingy used to be exchanged for goodies. :)

David Carlisle

@PauloCereda that's what I thought, the minimum unit of payment is £100 (I think) so I haven't any actual paper. The minimum payment is considerably more than I've got in 8 years: I think not posting anything and having readers that don't click on adverts doesn't help.

Paulo Cereda

@DavidCarlisle What if we all click an advert a day?

David Carlisle

@PauloCereda I'll get banned for having drawn attention to the adverts: like serial voting reversed, but more serious

Paulo Cereda

15:04

@DavidCarlisle oh no

Joseph Wright

@daleif Fun one :-)

daleif

15:31

@JosephWright strange definition of fun. Was just testing my new theme on old code and stumbled upon it.

Joseph Wright

16:03

@daleif A nice bit of detective work and an outcome that it's not my fault :-)

Alan Munn

@JosephWright Is it worth it to comment about someone who just turned my comments into an answer? I don't really care, but it's not the best practice to get into.

Paulo Cereda

\underbrace{\lambda}_{\text{função de}} \underbrace{x}_{x} \underbrace{.}_{\text{que}} \underbrace{x + 1}_{\text{incrementa valor de } x}

Guys, is there a way for me to keep this thingy equally spaced vertically? :)

Alan Munn

@PauloCereda Quick and dirty put \strut inside each of the first arg of the \underbrace.

Heiko Oberdiek

@PauloCereda or \vphantom{fçq}.

Paulo Cereda

16:19

@Alan, @Heiko: thanks, both approaches work. :) But only the last part seems unaligned, for some reason.

Joseph Wright

@AlanMunn Link?

Paulo Cereda

The last part is a little low, I guess.

Heiko Oberdiek

@PauloCereda The + has a descender, therefore, you also need \vphantom{+} in the math part.

Paulo Cereda

@HeikoOberdiek oooooh

@Heiko: thank you thank you thank you!

Heiko Oberdiek

@PauloCereda Or you can do the opposite: \mathbin{\smash{+}} for the visible plus sign.

Paulo Cereda

16:26

@HeikoOberdiek Is there anything you don't know? :)

Heiko Oberdiek

@PauloCereda I am afraid, lots of things, even things, where I do not know, that I do not know them.

Paulo Cereda

@HeikoOberdiek oooh :)

yo'

@PauloCereda We had an ice cream with @egreg today!

Paulo Cereda

@yo' yaaaaaaaaay

@yo' which flavour? :)

Q: RTL with tabluar

This is a question about xelatex, even though I mention LyX here. My goal is to produce an RTL table with one row, two columns, which looks more or less like that: +---+---+ ...

16:46

@JosephWright we went for a trip. I had to go there anyways. We've visited a nice historical town (with the 3rd largest Czech castle) and a small pittoresque castle in the middle of nowhere. In the evening, we'll go for a good local beer :)

egreg

@daleif Added to the memo

David Carlisle

@JosephWright since you keep telling me to fix xor I thought I'd read the doc to remind myself... `texdoc xor` shows a pdf that just shows the graph of a neural network or something and `texlua build.lua doc` in `xpackages/xor` produces `Typesetting xo-capt

David Carlisle

@PauloCereda not a bad amount:-)

Paulo Cereda

@DavidCarlisle Indeed. :) Speaking of which, @egreg is about to hit 400k. :)

David Carlisle

@PauloCereda he did tell us that every coffee break and meal time:(

Paulo Cereda

@DavidCarlisle LOL

yo'

17:55

@DavidCarlisle well, he surely didn't tell you because you were always at the L3 table, while @egreg was not.

Joseph Wright

18:14

@percusse Re the meta question: I did say keks was taking risk :-) (I'd already seen the answer he got)

percusse

18:37

@JosephWright True. And somebody got the bait :P

Joseph Wright

@percusse Indeed

@percusse I'm tempted to follow up on the main meta but it's non-productive

percusse

@JosephWright I think it's better to have the grunt on our meta instead. That would at least prevent the Meta.SO residents flocking to the discussion.

Joseph Wright

@percusse Exactly: on the main meta you are talking cross-network so our local conventions don't show

percusse

@JosephWright I (tried to) participate a bit on SO. That place is really interesting. But every time I engage with someone I always remember @AlanMunn's gem:

Dec 15 '12 at 4:10, by Alan Munn

@percusse Exactly. There's nothing more annoying than a bunch of disciples. :)

Joseph Wright

@percusse SO's scope is so huge I do understand why they have a different set of norms

@PauloCereda #4 is wrong (now)

Paulo Cereda

@DavidCarlisle Wait till the very end. :)

@DavidCarlisle Certainly if you want to be the British monarch

David Carlisle

@PauloCereda judging by your songbook I guess you are disqualified.

Joseph Wright

@DavidCarlisle Act of Settlement?

Paulo Cereda

@DavidCarlisle Uh-oh. :) And according to the British monarchy, catholicism is transitive. :)

David Carlisle

@JosephWright yep

@JosephWright xoutput.pdf has an interesting set of comments:-)

Joseph Wright

@DavidCarlisle The whole thing does!

@PauloCereda A long time ago I was in a car driving around the ring road in Milan and the Italian driver's hands were only on the steering wheel about half of the time.

@AlanMunn Sorry, was distracted! Thanks for that

Alan Munn

@ChristianHupfer No problem. It's a clever cartoon.

Christian Hupfer

@AlanMunn: In Germany we call this the Zeitalter des gesenkten Blicks...

Alan Munn

@ChristianHupfer Yes, there is that aspect of it too. :)
