@Werner the above extracts the Y coordinates from file1.eps and stuffs them in the bounding boxes of in all files File[a-z].es

egreg

@DavidCarlisle So I provided a much sleeker LaTeX3 version. :)

David Carlisle

@egreg I bet (without looking) that it looks less sleek if you put \tracingall at the top of the file

egreg

@DavidCarlisle What are some hundreds of expansions compared to eternity?

Werner

00:15

@DavidCarlisle Imma gonna test that out tonight.

Paulo Cereda

In the book contest, we have 59 answers, but only 30 upvotes in the main "question". Some people are greedy. :( I was expecting at least a 1:1 value.

Alan Munn

01:21

Ok. I finally succumbed and added my number.

@percusse Do you know how @Jake got the timestamp data for the meta question graph?

percusse

@AlanMunn I guess he read it manually from the answers but you never know :)

Alan Munn

@percusse That seems like a lot of work. And it's not clear that it's available simply by looking at the answers.

percusse

@AlanMunn Yep, he might have done it via something else RSS feed or something. I'm pretty ignorant about those.

Alan Munn

@percusse Yes, that's what I'm thinking, but I can't figure it out.

percusse

@Jake Enlighten us please.

percusse

01:44

@cmhughes Have you picked 99 or 199? Because I've added 99 and you have also marked 199. Am I missing something?

cmhughes

@percusse oh, did I screw up? I meant to pick 199...

percusse

@cmhughes No problem I'll remove the 99 marks.

cmhughes

@percusse when you say the marks, which ones do you mean?

percusse

@cmhughes the list in the question and the table with black dots. Your answer says 99 so I jumped on it.

cmhughes

@percusse oh, I meant to say 199. can't believe I've managed to bodge an answer on meta as well! I've changed my answer... 199

percusse

01:51

@cmhughes :) it happens

cmhughes

@percusse :)

percusse

OK now 61 answers 61 numbers.

cmhughes

@percusse sweet, thanks for noticing :)

percusse

@cmhughes I would like to thank my mild autism for this award.

cmhughes

@percusse did you see this one?

Q: Span a tikz chain over multiple pages

I wanna create a flowchart as a chain. What I want to achieve is a chain spanned over multiple pages on top of every page (see picture): For the example picture I created it manually (copied the code from texample.net, made a standalone chaine, cropped it manually in half and used eso-pic to p...

tikz-chains

I think @Werner's link is a duplicate...

percusse

01:57

@cmhughes I'll shut up for that. Lately I think I'm too trigger-happy for closing questions so I'm trying to stay away from voting. But it indeed looks like a duplicate with minor modifications.

cmhughes

@percusse ok, no problem :) I tend to be cautious about closing until the OP has confirmed via the comments, or doesn't confirm within a few days...

percusse

However I feel that TikZ is being forced to replace TeX and I don't feel comfortable with it. I've seen many instances that instead of proper coding people embed stuff inside tikzpictures.

cmhughes

@percusse yes, I agree... kind of makes me wonder if there might ever be a tikzTeX compiler

percusse

@cmhughes I don't know :) Right now, all I think about is to finish the final chapter of the thesis, do the hobby implementation and finish the Tikzkcd line style decoration. I couldn't make it to cjorssen's bounty heh.

cmhughes

@percusse good luck :)

percusse

02:02

@cmhughes Thanks a lot.

So should I flag this one?

Q: Avoiding bottomrule to go to next page

Sometimes my longtable bottom rules end up in the following page. How do I avoid that?

page-breaking longtable rules

cmhughes

@percusse I bet it'll be a master piece :)

percusse

@cmhughes not the thesis that's for sure. My second chapter is called Brief and Opiniated Literature Survey. I got a go-for-it signal from my supervisor. My academic life will be short.

cmhughes

@percusse geez, that guy needs to chill out... I've got your back, I'll comment back

percusse

@cmhughes Oh no leave it alone :)

cmhughes

@percusse I'll be polite :)

percusse

02:05

@cmhughes Don't touch it please. We had enough of these stuff lately.

I'm not offended by those stuff. And it doesn't work anyway.

cmhughes

@percusse alright, as you wish :)

percusse

I mean the minipage stuff

cmhughes

@percusse so were you flagging it as not an answer?

percusse

@cmhughes yep before that comment. Now I'm leaving it alone

Apparently, my comment worked :)

cmhughes

@percusse some people have real problems :)

percusse

02:10

@cmhughes I thought it was OK for a person who goes MoFo in the answer but no.

cmhughes

@percusse dang....

@percusse there are so many things wrong with that answer

percusse

@cmhughes It's internet, I'm not fighting with it.

cmhughes

@percusse I commented- if you want me to delete, let me know

percusse

@cmhughes Oh please as you wish. It's just that I'm not offended about those flaming stuff.

cmhughes

@percusse no worries- I wanted to point out to him/here (politely) that their answer is flawed

@percusse so how many chapters then?

percusse

02:22

@cmhughes 6 now if I can finish it this weekend. I'm so anxious to get my life back :)

cmhughes

@percusse think of the reward :) you can do it! I do remember the feeling- it consumes you so completely

percusse

@cmhughes Then I can write the fun part which are the 10 propositions that you have to hand in. 5 technical 5 non-technical . People usually put wise statements in there but I have a different idea :)

cmhughes

@percusse do tell :)

percusse

The jury can ask about those ones during the defense instead of the thesis so I'll see what I can do.

Well I can give one for the teaser.

I have hardly ever known a mathematician who was capable of reasoning. Plato (400 ±50 BC)

hehehe :)

@cmhughes back then apparently mathematician meant something else.

cmhughes

@percusse lol :)

percusse

02:28

my supervisor is a mathematician so a tough discussion awaits me.

cmhughes

@percusse what's the field of the thesis?

and more importantly, how many overfull hboxes? :)

Alan Munn

@percusse Hopefully it's "opinionated" rather than "opiniated" or your academic life will be even shorter. :)

percusse

@cmhughes It's about haptics and teleoperation (kind of robotics stuff)

currently 112 pages and 5 overfull hboxes :)

@AlanMunn Checking immediately.

:)

@AlanMunn Phew, I was smarter when I was writing it.

Alan Munn

@percusse Of course you could always use "opiated".

percusse

So it's safe. I might go with Opiumated

Alan Munn

02:38

After all, lit review can put anyone to sleep.

cmhughes

@percusse cool, sounds like fun :) that's an impressively small number of overfull hboxes too :)

percusse

@AlanMunn Not mine. I've already received hate mails from big shots.

Alan Munn

@percusse That opinionated, huh? Good for you. Do you have a great positive proposal to replace the criticisms?

percusse

You should see my talks in the conferences. You can smell the rage. Luckily I can prove what I say and passed the most excruciating review stage which is my supervisor. :)

@AlanMunn Yes hopefully the stuff we are implementing to our robots will prove a point.

Alan Munn

Cool. That's good. What's next when you're done? Riches in industry or an academic position?

percusse

02:41

@cmhughes Well I've learned a lot here.

cmhughes

@percusse the earth is definitely flat, don't listen to what the conference people tell you

percusse

@AlanMunn I think with that intro nobody will hire me. so I'll try to be a proper engineer again.

cmhughes

@percusse indeed, me too :)

percusse

@AlanMunn Here are my current boss' thoughts about academia. steinbuch.wordpress.com/2012/12/05/…

Alan Munn

@percusse Yes, very stimulating. :)

percusse

02:44

He is quite fun to work with.

Alan Munn

He seems like a very smart guy, that's for sure.

percusse

And this is not the mathematician, he is the practical guy. So I have two promoters. So that was quite a challenge to please both sides.

cmhughes

gotta go for now guys, speak to you soon :) have a great weekend if I don't see y'all around in here :)

percusse

@cmhughes You too. See you later.

Alan Munn

@cmhughes Bye.

@percusse So does he drive a Tesla?

percusse

02:49

@AlanMunn He's getting it in 3 weeks. He already got a Roadster if I remember correctly but I guess he sold it.

Alan Munn

@percusse Very cool. Will he let you have a spin?

percusse

They had a Model S testdrive and he was flabbergasted.

Alan Munn

@percusse Yes, I fumbled my way through his review. My Dutch is rudimentary, but I kind of got the gist.

percusse

@AlanMunn He asked me himself once. Also he said we should buy together with 8-9 guys and have it on rotation.

@AlanMunn I'm always amazed by your linguistic skills, I don't think it's just your profession. You have something apparently that I have none.

Alan Munn

@percusse Although I really only speak English well. I'm actually a terrible language learner, because of two personality traits: I like to talk intelligently and I'm somewhat perfectionist. Those two combined are a recipe for non-attainment of a second language.

Good second language learners don't mind talking like children for a while, and don't care (at least initially) about their mistakes.

What I do have is a good understanding of how a bunch of languages work. I know quite a bit about the syntax of both German and Dutch, so that can help a lot.

percusse

02:56

@AlanMunn Heh, other than the at least initially part that's me.

Alan Munn

@percusse I doubt it. You guys in the Netherlands suck up languages like water it seems. You all start really early (which is essential), and you're so convinced that no one would ever want to learn Dutch it's almost national pride to be at least bilingual.

percusse

@AlanMunn Well, I've come here 5 years ago from Istanbul so that was also my impression. I'm still not very fluent because the slightest mistake triggers the switch-to-English mode. So you miss the opportunity. But indeed it's a great thing that everybody speaks at least English as a second language.

Alan Munn

@percusse I didn't realize that. So your native language is Turkish? That's a cool language.

percusse

Yep. And Dutch when I'm drunk :)

Alan Munn

@percusse Yes, everyone I know who's lived in the Netherlands has encountered that "we won't put up with your Dutch" phenomenon. It can be very frustrating for academics who are supposed to learn the language in a particular amount of time and conduct administrative tasks in the language.

percusse

03:05

@AlanMunn I've found a middle way. They laugh at me when I screw up and tell me the mistake. It was quite painful indeed heheh. The typical mistake I did was vlees and fles. So I kept on asking for meat in the bar for a bottle.

@AlanMunn w,v, and f was practically indistinguishable for me for a while.

Alan Munn

@percusse LOL. Turkish has f and some weird v sound that's not v right?

percusse

@AlanMunn Whenever you are around let me know and I'll take you to this shop wynand-fockink.nl ;)

It's a work safe website no worries.

Alan Munn

@percusse LOL. That's hysterical.

percusse

@AlanMunn It's a great place too.

We have some weird characters but the pronunciation is pretty consistent. So maybe you mean the soft-g. The weird characters are here. zargan.com

And the capital I with a dot.

Alan Munn

I remember once a friend of mine's mother was visiting from France. In Canada there is a big seal fur industry, so it's common to find lots of seal toys and things. Now the French word for 'seal' is 'foque', so she went into a store a said "I like a little foque".

percusse

03:12

@AlanMunn Oh my. hahahah

Alan Munn

@percusse No, I'm thinking of the pronunciation of the 'v' in (maybe?) 'gâvur'

percusse

@AlanMunn Hmm that sounds like the usual v. Ah, yes maybe you are right. If I speak fast enough it comes quite close to an f

@AlanMunn But the f is usually too strong to be mistaken. So indeed for a non-native it might be problem.

Alan Munn

Yes, I think it's not actually a v like the English v in most words. It disappears altogether in words like 'sövmek' I think.

percusse

@AlanMunn Spot on. How come you know this much I have no idea. Hats off.

Alan Munn

@percusse Here I'm cheating from Wikipedia. The only thing I know about Turkish phonology is what's called 'vowel harmony' for which it's famous. Every linguistics student learns about it. And they usually do a problem or too on the morphology (word structure) which is quite fun too.

So (with some exceptions I'm sure) every word in Turkish has to have either all front vowels or all back vowels. It's a classic and difficult phonological problem.

percusse

03:23

@AlanMunn Yep, it's also difficult for us in the high-school exams. :)

Alan Munn

@percusse Really? Is this something that native speakers have trouble with?

percusse

But it's a good (not super-consistent) test to see whether it's an ancient Turkish word or Arabic-Persian-French-English hybrid.

Alan Munn

@percusse I see, because the latter don't observe the rule?

percusse

@AlanMunn Indeed.

@AlanMunn The natives have no problem with it but teachers make quite difficult questions using that stuff.

Needless to say I suck at classic literature :)

Alan Munn

So is the "error" to regularise the borrowed words, and the educated speakers have to know all the exceptions?

(By regularise I mean make them have harmony.)

percusse

03:27

@AlanMunn The main difficulty is that there is another rule. The one you mentioned is called the Big-Vowel-Harmony and we also have a Little-Vowel-Harmoy rule.

@AlanMunn Oh no problem using the language by the way. This is all exam stuff that you have to answer correctly and state the rules precisely etc. People just use their instinct while speaking so you don't need to follow any cognitive construction.

Hmm let me see if I can find a proper translation of it.

Alan Munn

@percusse Ah, ok.

percusse

OK let me try :) 1) If there is a flat(?!) vowel (a, e, ı, i) in the first syllable in a word, the rest of the vowels trailing in that word must be in that set. 2) If there is a round(?!) vowel in the first syllable in a word the following vowel must be either narrow (?!) round (u, ü) or wide flat (a, e) .

Does that make any sense?

Alan Munn

03:49

@percusse Yes. In phonological terms we use front vs back and round vs. unround plus high vs low. So what you're calling flat is unrounded. And your narrow round are high round and wide flat are low unrounded.

The way this is represented in phonology is with a multi dimensional structure where the feature 'spreads' onto the subsequent underspecified vowels in the suffixes.

percusse

@AlanMunn Wow it doesn't feel this complicated when I speak it heh.

Alan Munn

@percusse That's the recurring story of all things cognitive.

It's also what makes linguistics so hard for people. Language is so automatic for us that we can't believe how complicated it really is.

percusse

@AlanMunn I can imagine. Also it should sound pompous if it needs to be a proper theory :P

Also I'm involved with the sense of touch and it's practically the same story.

Alan Munn

@percusse Right. And vision etc.

@percusse Now I know why everyone loves you.

percusse

@AlanMunn You can feel it, right?

Alan Munn

03:59

@percusse I'm feelin' it now, dude.

percusse

@AlanMunn I can't stand snobbery of any kind. Somehow it's burned on my chip and my radar is always open. Of course occasionally it triggers false positives and I get into trouble.

Alan Munn

@percusse There's a funny relationship between snobbery and distance from the people at the centre of a theoretical paradigm. Those closest to the top people tend to have a less reverent view of the theory than those more to the periphery. But maybe this is just particular to linguistics where Chomsky has had such a massive influence on the field for so long.

percusse

@AlanMunn I can also identify that in my field too. There is an unjustified hype about axiomatizing and praising the holistic attitude extensively. However, big shots are less prone to being stuck in such situations and they can simply look for the nearest pragmatic exit. Obviously that exit becomes an element of the Axiom Set almost immediately with a pompous motivation.

Alan Munn

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

percusse

@AlanMunn Hahaha that's a great summary! Great stuff. I'm stealing it immediately.

Alan Munn

04:17

@percusse You can put that as the subtitle to your Opinionated Literature Survey !

percusse

@AlanMunn Even better, I'm gonna make it a proposition.

Alan Munn

:)

Anyway, I'm taking off. As always, it's been really fun chatting with you. Have a good middle of the night. (Do you ever sleep?)

percusse

@AlanMunn Likewise. The pleasure is mine. (I'm not sleeping well lately. Reduced to 2-3 hours a day. But good days are coming )

Alan Munn

@percusse Well as they say, sleep is for the weak. Good night.

percusse

@AlanMunn :) I want to be one of them

Good night

Jake

Cmhughes changed his number, is that right?

@Jake No, he wanted 199 from the beginning; see his meta answer. But, when he edited it in, he made a typo which percusse fixed, if I am not wrong.

I'd like the screen to take half my laptop's width and all its height.

@PauloCereda I dunno, I said "DEK is Who", you said "just the Doctor", which means that "DEK is Doctor, but DEK is not Who", doesn't it?

Paulo Cereda

@tohecz You said DEK is Who, then I said it's just the Doctor, hence DEK is Doctor iif it's not Who. :)

tohecz

@PauloCereda I'm so looking forward to confusing my students this way, if I ever teach logics ;)

Paulo Cereda

@tohecz Please do it. :)

tohecz

@PauloCereda actually, it is not necessary. I teach Discrete Mathematics, which is kinda simple thing for understanding, you only have to put the simple things together the correct way. We give the students simple problems, they can solve them, present their solution and get some extra points (some students don't even have to pass the final test if they have enough points). And believe me, the students often confuse themselves enough ;)

egreg

14:21

@StephanLehmke What do you mean with "the table is overfull"?

Stephan Lehmke

@egreg The total width of content is more than the specified width of the table.

egreg

@StephanLehmke I don't understand.

@StephanLehmke And your last response is even more obscure.

A: Who Wants to Win a LaTeX Book?

Stephan Lehmke

@egreg Hmm. Sorry to not make myself clear. AFAICS, there are (basically) three table environments where you can specify the desired total width of the table: tabular*, tabularx, and tabulary. If the total width of the material in the columns would naturally be larger than the given width (the "overfull" case), then there has to be some automatic line breaking. tabularx and tabulary can cope with that, but not tabular*. (ctd.)

(ctd.) If the total width of the material in the columns would naturally be smaller than the given width (the "underfull" case), then there has to be some stretching. tabularx and tabular* can cope with that, but not tabulary. So it seems only tabularx can cope with both cases.

egreg

@StephanLehmke The purpose of tabulary is precisely not to stretch columns that don't need to.

Stephan Lehmke

15:46

@egreg Well the documentation says no such thing. This would mean the given length is the maximum width. There at least should be an option to switch between maximum and actual width, as both have their purposes.

egreg

@StephanLehmke If the total natural width of the material doesn't exceed the target length, the package has nowhere to act for reducing it. At least this is how I interpret the way it works.

Stephan Lehmke

16:19

@egreg That's again a technical explanation. But (a) I don't find it unreasonable to expect that if I specify a width for the table, it will be rendered with that width and (b) tabulary seems to be able to achieve this, as I basically disabled an automatic truncation.

@DavidCarlisle Maybe you can explain why tabulary is purposefully behaving differently from tabularx if the material in the table does not "fill" the given width?

There is a case distinction here

 \ifdim\TY@tablewidth <\TY@linewidth
   \def\TY@ratio{1}%
 \fi

Without it tabulary will "stretch out" to the given width like tabularx does.

@PauloCereda Of?

Paulo Cereda

@JosephWright of eqnarray. :)

I had no idea what's idea behind this "question". :)

@JosephWright: The user probably needs to fit that entry in the Q&A format.

@PauloCereda Eager to share knowledge and pleasure of knowing something combined :)

Paulo Cereda

@percusse ooh that's deep.

Let's wait for the first wise guy that wants to build arara from sources but didn't follow my instructions on localization to fall in my trap: github.com/cereda/arara/blob/master/application/src/test/java/…

:P

percusse

@PauloCereda I'm in a good mood. All my factorizations are square, biproper, and bistable. (Rest assured it's a good thing)

Paulo Cereda

@percusse Oh my. Matlab is working?!

percusse

@PauloCereda Let's say I've convinced it. I have epsilon1 to epsilon56 to tweak stuff up. Little there little bit here, a spoonful of machine precision over there....

Paulo Cereda

@percusse ooh! :)

@PauloCereda I'll publish them as universal matlab constants later

@percusse LOL good one. :)

@percusse: I want to write a Matlab code which prints an array of NaN's and append "Batman" to the end.

ans = NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN NaN Batman!

egreg

@PauloCereda ans~=~\prg_replicate:nn {11}{NaN~}Batman!

Paulo Cereda

@egreg OMG! <3

@PauloCereda Remember \ExplSyntaxOn and \ExplSyntaxOff

percusse

@PauloCereda sprintf(horzcat(num2str([1 zeros(1,10)]*inv(zeros(11))),' Batman\n'))

Paulo Cereda

@egreg Sure. :)

@percusse OMG²!

You sir are the Matlab wizard.

percusse

@PauloCereda Ah, how I wish.

Speaking of which let me show another wonderful thing about matlab

I invert a zero matrix first: inv(zeros(4))

ans =

   Inf   Inf   Inf   Inf
   Inf   Inf   Inf   Inf
   Inf   Inf   Inf   Inf
   Inf   Inf   Inf   Inf

So nice and clever

then I convert this to string

num2str(ans)

ans =

Inf  Inf  Inf  Inf
Inf  Inf  Inf  Inf
Inf  Inf  Inf  Inf
Inf  Inf  Inf  Inf

Come on matlab you can pull this off.

Then multiply the result by 2

2*ans

ans =

   146   220   204    64    64   146   220   204    64    64   146   220   204    64    64   146   220   204
   146   220   204    64    64   146   220   204    64    64   146   220   204    64    64   146   220   204
   146   220   204    64    64   146   220   204    64    64   146   220   204    64    64   146   220   204
   146   220   204    64    64   146   220   204    64    64   146   220   204    64    64   146   220   204

I'm starting to get annoyed. Three new entries, no new upvotes.

@PauloCereda By the way the result is a double again :)

@PauloCereda No need to be annoyed.

@percusse :D

percusse

It's just what it is.

Paulo Cereda

@percusse Indeed.

Torbjørn T.

@percusse Is disp([num2str(NaN(1,10)) ' Batman']) too easy?

percusse

@TorbjørnT. No not at all. I stopped using that array generation due to some terrible experience :) Clever solution anyway.

I don't trust the machine so I'm deliberately multiplying things with Inf to get a NaN heh. In some occasions it passed the number tests as being a string so I'm over-cautious.

Torbjørn T.

18:52

@percusse Thanks. I haven't used Matlab enough to have had many terrible experiences, I think.

@TorbjørnT. You can see one above :)

Hi, anyone here with experience in repairing HP printers? I'm trying to replace the PCA controller in a Laserjet 4000 and can't figure out from the service manual what is the minimal amount of things I need to take apart to get to it.

@StephanLehmke perhaps it seemed like a good idea in 1995?

@egreg Oops that's subject to charge. Should I get my message zapped?

egreg

@StephanLehmke Why? But I don't think this is the right place for such queries. :)

percusse

@PauloCereda @StefanKottwitz Is there any planned schedule to update the texdoc server? Some of the package links are pointing to older versions. I guess it's because the distro on the server is still not updated.

Stephan Lehmke

@egreg Being interested in TeX is a sign of excellence ;-)

@StephanLehmke You are describing Paulo no? :)

Just clone him.

Stephan Lehmke

@percusse Maybe you could provide some kind of robo-clone equipment with an uplink to Sao Paulo?

He's awake 24h anyway ;-)

percusse

@StephanLehmke :-) Well, the clone would be awake too. But then he can run the chat bot safely.

Q: Update bounding box in one EPS with values from another EPS

I create a large number of images in LaTeX (mostly pstricks). Some of these images form part of a sequence showing the progression of some algorithm. The progression adds or removes content from the image, which effectively influences the image size, and consequently also the bounding box that su...

regex perl latex bounding-box eps

This originated from this chat with David.

Sorry @DavidCarlisle, TeXnicCentre requires something a little more self-contained, rather than a nifty grep/sed combination. Hence my request for a perl script...

@Werner You want me to write a Java code?

Speravir

@PauloCereda I can only speak for myself, but perhaps this is also right for the others right before me: I already have upvoted some days ago, but added an answer today.

David Carlisle

@Werner can't you give it a shell script/bat file with any combination of commandline?

Stefan Kottwitz

@percusse I updated to TL 2012. Which package for example?

Speravir

Ooh, hello @StefanKottwitz: I waited for an moderator: I want you to immediately reopen tex.stackexchange.com/questions/87075/… after I made the last close vote. Cf. comment of mine and of Christian. As I made the edit, there were 2 close votes – now there are 4, what means, that 2 people can’t read correctly.

Stefan Kottwitz

@Speravir NARQ may be invalid, but it looks like a duplicate

@Speravir many times there's just a clash because of the same macro name. And \ifpdf is very common, we had it here

Speravir

23:57

@StefanKottwitz Oops. But the close votes are for NARQ … and now?

Stefan Kottwitz

@Speravir perhaps not for the same class, but with the same reason and similar fixes

Speravir

@StefanKottwitz And BTW it seems to be a bug in this class, what usually makes it TL. Or not?

Stefan Kottwitz

@Speravir I still can change that to a dupe closing, if we would find a good original

perhaps even better than tex.stackexchange.com/questions/11414/package-ifpdf-error
