12:00 AM
@PauloCereda Don't say "as better" when Alan's around. :)
 
@egreg Oops.
 
@PauloCereda Just in time to correct.
 
@egreg Shhh he can hear us. :)
I love "The Bishop" sketch from Monty Python, specially the gangster-style of the bishop. "We was too late. The reverend Neuk saw the light." :P
 
@egreg Ok, now you've done it: that should have been "next time you're on-line" :P
@egreg Ambiguity is more economical.
 
@AlanMunn Why not the future tense?
 
12:08 AM
 
@egreg I actually don't know offhand. It seems related to the fact that you can't have the future in in a conditional in English: If he leaves... not If he will leave.
 
@AlanMunn Why are languages so different? :)
It would be much easier if everybody talked Italian. :)
 
@egreg And yet they must fundamentally be all the same at the right level of abstraction. That's the real puzzle.
@egreg But variation is built into the system, so even if everyone spoke Italian, given enough time, everyone wouldn't any more.
 
@AlanMunn I'll think to the right level of abstraction tomorrow. Now it's bedtime. Bye.
 
Let's invent a new language! :)
@egreg Buonanotte! :)
 
12:19 AM
And what is this "Italian" that you speak of? Piedmontese? Ligurian? Venetian? :-)
@egreg When you've solved it, let me know. Good night.
 
Cool, first trailer of Ice Age 4!:)

8:54 AM
@GonzaloMedina Congratulations for your 40000
 
9:15 AM
@AlanMunn No, he hasn't. I'm not going to pursue the matter further. His last comment in chat could be taken as meaning that this was just the final straw. He's been back on the site since, so I guess from that that he does not want to discuss it further. His intention now seems to be simply to delete all of his contributions, so all I'm going to do is vote for them to be undeleted (it needs 3 such votes, or one from a moderator).
On another matter, has anyone read the blog post blog.stackoverflow.com/2012/03/… ? My "favourite" bit is where they say "we won’t display reputation lost to deleted questions on your profile unless you explicitly ask for it, and won’t display it at all to other people". This makes egreg's profile page even more, well, I want to say insulting. Have the SE mods explained anything to our mods?
 
Heh, the next sentence after the one you quoted has egreg in it :P
 
9:32 AM
@RoelofSpijker I missed that! So Americans do know the meaning of the word "irony".
 
9:52 AM
@AndrewStacey I am sorry to see the recent chat between you and Marc and my opinion there are misunderstandings from both sides. However, I think you should grant Marc the right to delete his posts. Making a statement that you will vote to undelete them is adding fuel to the fire.
 
@YiannisLazarides Sorry, but no. He can disassociate himself from his posts. But he does not have the legal right to delete them, and he certainly does not have the moral right to do so. Frank was worrying recently about what happens if SE goes under and all the information disappears from the internet. It's not on the same scale, but a user deleting their answers and questions is the same activity.
The SE team actually take this quite seriously: Marc's activity has been noted by the software and it is actually getting blocked: his most recent deletions have been flagged as "Vandalism".
(Flagged by the software, that is.)
Incidentally, I deeply regret what has happened, but - sort of obviously - don't see where the misunderstanding has been from my side. So that I could avoid the same thing happening again, could you tell me what my misunderstanding was?
 
10:18 AM
@GonzaloMedina: Congrats!
 
10:35 AM
@AndrewStacey Part of the misunderstanding is that some people feel badly when a question is proposed to be closed as duplicate. Andrew I am also of the opinion that he has the prerogative to delete his posts and you have the right to vote to undelete them. As to the moral right I will leave that to a philosopher. However, he did contribute well and at a stage he posted his LaTeX book online for free. This is the type of user we don't want to lose.
@AndrewStacey I am also not sure that vandalism is in place here. His answers are one of many on questions and will remain visible to high rep users. I don't want them to be deleted either but for sure I wouldn't call them vandalism.
 
@YiannisLazarides If that is the misunderstanding, then it is not mine. I did not vote to close the question as a duplicate (I did not vote to close the question). I did not say that the question should not be on the site. I asked for contextual information. As for the right or prerogative to delete his posts, 'fraid not. All content is licensed under a CC-by-SW so once posted, the author's wish to remove it can be overridden. The fact that high-rep users can still see his posts is moot.
It's the low-rep users that are important here.
The word "vandalism" is that chosen by the SE software, not me.
 
I need enlightment. Should I use (a) "Another possible cause is due to a very unstable internet connection." or (b) "Another possible cause is a very unstable internet connection." ?
 
@PauloCereda Depends on whether the internet connection caused the cause or is the cause.
 
@AndrewStacey Ah I see. The internet connection is the cause. :)
 
@PauloCereda Then the second.
 
10:49 AM
@AndrewStacey Thanks a million, Andrew! :)
 
@AndrewStacey Do you have a link to the question, I want to have another look but don't seem to find it.
 
@YiannisLazarides I wish I did! I would like to take another look, but it doesn't appear in the list of recently deleted questions (not sure why - maybe because the asker deleted it and it had no answers).
A-ha! Just found it in the undelete votes list and have cast the final undelete vote so it can now be seen at: tex.stackexchange.com/q/46798/86
 
@AndrewStacey Thanks. You know all the secret places:)
 
@AndrewStacey Now I can read the comments.
 
Cool! I want a bird. :)
 
11:05 AM
I've just added the result of the TikZ code. Sadly, I can't reconstruct the original inspiring picture.
 
@AndrewStacey The give away on the image is probably the birds flying in the opposite direction. mcescher.com/Shopmain/ShopEU/facsprints-uk/data/250/…
 
@YiannisLazarides Wow! I saw this picture in a 50 years old book.
 
@AndrewStacey I used to have a few books of Escher's works. Got introduced to it by a Penrose book:)
@AndrewStacey Anyway I read the comments, the offensive action does not belong to you, but the fact that the question was voted to close might have been the reason. A bit of a rephrasing of the question would have been fine, maybe ... how do I draw a tesselation efficiently with TikZ? Maybe also the tone? ... and the question...is?
 
TeX troubles again, but I think this is a real quickie. Can any of you tell me how do I get an integral sign with $R$ beneath it instead of the circle?
 
@KannappanSampath No, it's not a quickie. :) Have you got some reference for such a symbol?
 
11:17 AM
@egreg Then shall I ask on the site?
@egreg No, but I just want to tweak and in the place of the circle put $R$.
 
@KannappanSampath The "circuit integral" is a glyph by itself, it's not made from an integral and a circle.
 
@egreg oh, my bad then. I knew that $\oint$ existed and I thought tweaking its code would give me this thingie. No?
 
@KannappanSampath Sorry no. Does this R-integral have limits above and below?
 
@egreg Yes. Is that bad?
 
@KannappanSampath No. It would be best if you pointed at some place where it's used.
 
11:22 AM
I mean I am typesetting notes where I begin with Darboux's formulation of the integral and say that it coincides with Riemann's. So, provisionally for establishing the notation, I would like to use $R$ integral.
@egreg Sorry for forgetting to ping you, but I am not sure if anybody thought of this crazy $R$ integral but as I said above, may be I am the only crazy guy to have come up with the idea. : (
 
@KannappanSampath You can try this
\usepackage{mathtools}
\newcommand{\Rint}{\mathop{\mathrlap{\mkern2.5mu R}}\!\int}
 
@egreg Thank you for the swift response. I am waiting for TeXmaker to tell me something.
Ah it shouts at me. There are many errors let me retry.
@egreg Thank you, it compiled. I'll upload the output. Can you give me sometime?
 
@KannappanSampath Try this, that works also in text style:
\usepackage{mathtools}
\newcommand{\Rint}{\mathop{\mathrlap{\pushR}}\!\int}
\newcommand{\pushR}{\mathchoice
  {\mkern2.5mu R}
  {\scriptstyle R}
  {\scriptscriptstyle R}
  {\scriptscriptstyle R}
}
 
@egreg Do you mean the previous thing works in text mode as well?
 
@KannappanSampath No, but it will give decent results as $\Rint_a^b f$
 
11:36 AM
 
By the way, do you know what are all the divisible abelian groups?
 
$\Bbb R$, $\Bbb Q$, $\Bbb Z_q$ for prime power $q$ come to mind. But I am a bit afraid if this is a thorough list.
@egreg Again the ping. Sorry!
 
@KannappanSampath They are arbitrary direct sums of Q and of the Prüfer groups; we use to denote them as $\mathbb{Z}(p^\infty)$. This was the question my Higher Algebra teacher asked me to get evaluated "cum laude" at the exam. :)
 
@egreg The very precise output, I think I should have asked in the site for others benefit.
 
@KannappanSampath Do it, I believe it's an interesting question.
 
11:44 AM
@egreg Very interesting. But, I must have got the prufer group. This direct sum thing as well. But are these the only ones? (Upto Isomorphism)
And, if so, I'd like a proof. Let me think.
@egreg I'll do so now.
 
@KannappanSampath Yes, they are. The fact is that Z is a noetherian ring and the divisible groups are precisely the injective Z-modules. Therefore the torsion part splits and the torsion-free part is a Q-vector space. Then one can split the torsion part into the p-components and they are easily seen to be direct sums of copies of the Prüfer groups. :)
 
@egreg I was thinking in group theoretic terms. My bad. Thanks for asking and sharing this beautiful problem and solution with me.
 
@KannappanSampath On a noetherian ring all injective modules are direct sums of indecomposable injective modules
The former is a complete classification up to isomorphisms.
And there's a nice connection with Pontryagin duality, by the way.
 
@egreg This may sometime be definitely a blog post for my blog. Amazing and just spell bound.
@egreg I am not proficient in anything beyond modules. I am only a freshman at my institute. But, would like to listen from you.
(I'll keep a Text file and think about this as I get to know the details.)
 
My... brain... hurts... so... much. :P
 
11:56 AM
What is the suitable tag for this question @egreg?
@egreg I have asked the question with a symbol tag here
Looking forward to accepting your answer. : )
@egreg The system does not allow me to accept an answer. Do you know why?
 
@KannappanSampath You have to wait for a period
 
@KannappanSampath I think you need to wait at least 10 minutes, I guess. :)
 
Thanks both of you. @JosephWright @PauloCereda
@egreg Thank you for the help. I thought you were going to tell me more details about the prolem, though.
 
12:21 PM
@KannappanSampath I've added some explanations
 
@egreg oh, I meant the classification problem.
But, I'll check this out. : )
 
Hmm, lots of coffee mugs and donuts I see.
Wow, quite a lot happened since I checked the chat.
 
I'll think about this and at some point I may get back to you for some details. Will you reply my email @egreg?
 
12:42 PM
I am off. I'd like to continue the TeXing. Hope egreg replies with a ping. : )
 
Hello everyone :-)
Do you know of any other tools than GhostScript and xpdf that can convert PDF figures to EPS? All tools I know are based on one of these two. When I convert, quality gets reduced and the file size gets blown up significantly. The guidelines of the journal say that they only accept EPS figures with LaTeX (strangely they do accept PDF when not using LaTeX for submission ...)
 
1:01 PM
@Szabolcs Interesting. Why would the quality be reduced (and how do you measure it)? Do you get any warnings?
 
@AndreyVihrov I have some shadings/gradients in the PDF. I was told that is what is causing the trouble. I also have a big bitmap embedded in the PDF. Still, the PDF is 300 kB while the EPS is between 3000-10000 kB depending on the tool (and version) I use. When converting back to PDF, the size doesn't go down any more. Also, one tool seems to convert each pixel to a polygon in the image. With the other tool, the edges of the (few) polygons that make up the colour bar become visible.
I am trying to get the original producer of the figures to give me a correct EPS output now.
Out of curiosity, is there any acceptable technical reason the journals wouldn't accept PDF figures? They didn't reply to my mail asking about whether PDF is also acceptable, and when I called them on phone, they just said "they can't help me"...
 
@Szabolcs I guess you can't lose much if you ask a question on the site. I would also like to see where the problem is.
@Szabolcs Like anywhere, they probably stick to a many years old production process and are afraid of new changes. I don't think there is much problem on the technical side. (But maybe someone will correct me.)
 
@egreg: Today there's a big game on TV: Arsenal vs. Milan. :)
 
I think I won't ask on main because the problem would be specific to my file.
In the meantime I managed to get the original figure producer to give me EPS files at the correct size.
The frames are a bit misaligned, but at least the files are not huge.
Also, dvipdfm gives me plenty of warnings on them, but the PDF output looks fine apart from the slight misalignment.
 
@Szabolcs OK. You can also try Inkscape.
 
1:16 PM
For conversion you mean? Great idea, I'll try it!
 
@Szabolcs acrobat can save as eps, if you have the free reader version you should be able to print to postscript (just choose any postscript printer driver and print to file) might take a bit of postscript cleanup to make eps but....
 
@DavidCarlisle Oh right! Evince (probably through poppler) also can print to PostScript.
 
@PauloCereda: If Arsenal put on the same poor show they did two weeks ago it won't be much fun :(
 
@Roelof: Agreed. :) Van Persie did nothing in that game. I read on the sports section today that Arsenal believes they will revert score. I don't think they can. :)
 
1:32 PM
@egreg:

Q: Why setting 'predisplaypenalty' to 0 is wrong idea?

IchibannIn Vertical space between section header and text is too big user egreg said that setting \predisplaypenalty=0 is wrong idea. Why is that? Could you provide an example?

 
I'd say "In egreg we trust." is a valid answer. :)
 
@PauloCereda I think @egreg's original explanation is good enough already
 
@AndreyVihrov Ah true. :) I didn't see the original answer. :)
 
@AndreyVihrov I'd rather cut my arm off. :)
@AndreyVihrov Happily Mico saved me from that answer. :)
 
Yeay! Only sin, cos and tan to go, and the new l3fp will be ready.
Hi guys :).
 
1:47 PM
@BrunoLeFloch Great
@BrunoLeFloch How's the PhD?
 
@JosephWright ... please don't ask ;-)
 
@BrunoLeFloch Are the values calculated through a power series?
 
@AndreyVihrov Power series are bad at convergence
The current l3fp does as much work as possible without them, so I assume this remains the plan
 
@AndreyVihrov I've only coded basic arithmetic, ln, exp and ^. The latter three are done by a combination of table look-up and Taylor series (after some subtle tricks that Joseph unearthed for ln).
@JosephWright Well, at the end of the day, you still need power series (once you've reduced the input to something small), no?
 
@BrunoLeFloch Not my ideas! I got them from fp.
@BrunoLeFloch Unless you do something like CORDIC then yes
I did say 'as much as possible'
 
1:51 PM
My plan for trigonometric functions is to follow what you did, more or less.
 
Yay @Bruno is back! :)
 
no cordic.
 
@BrunoLeFloch I'd assumed as much :-)
 
Hello @Paulo
 
@JosephWright, @BrunoLeFloch do you know how the values compare with those from trig package
 
1:51 PM
@BrunoLeFloch No: I read a lot about it, and decided that a decimal CORDIC would be a pain in the neck
 
Hi @Bruno, how are you? :) We miss you. :)
 
@DavidCarlisle Speed or accuracy?
 
@JosephWright either (actually at the time i was trying to minimise token use as well, trying to keep te whol ething running on emtex...)
 
@PauloCereda I miss you guys too (although there are lots of team emails going back and forth, so I guess mostly egreg and you :)).
 
@BrunoLeFloch Do you also cache values? So that calling sin(1.2345678) ten times computes the value only once.
 
1:53 PM
@AndreyVihrov You can't cache for an expandable function. You have to have a separate cache step (as trig does)
 
@AndreyVihrov This is a little bit tricky.
@DavidCarlisle what's the accuracy of trig?
 
@DavidCarlisle Accuracy for current implementation is 8 d.p., but as it's not expandable there is caching
 
@JosephWright Ah, indeed.
 
@JosephWright I'm planning to add caching to the explicit \fp_sin:Nn if we keep those.
So if someone plans on having lots of repeated values, he can use that.
 
@BrunoLeFloch Yes, either than or a 'compute sine table' function
 
1:54 PM
@BrunoLeFloch oh I'm sure it's brilliant:-) (actually as I recall it wasn't bad for sin and cos, tan I sort of gave up on around the edges of the range)
 
:3708696: Yeah, he didn't show much in the interland agains England either. Doubt if they'll be able to make up the difference, ACM has a very strong team.
 
@DavidCarlisle I'm going for an IEEE-854-compliant fpu.
 
@DavidCarlisle There is nothing wrong with trig, but for Frank's coffins stuff real fp work seemed sensible
@BrunoLeFloch Then you decided on this plan!
 
In particular, with support for +0, -0, nan, etc.
@JosephWright Yes. Although I've been a bit lazy and not implemented denormals properly. That can be added later.
Also, I still don't know what range of exponents to choose.
 
@BrunoLeFloch For trig?
 
1:56 PM
@JosephWright sure the rules are rather different now. Frank and I had just spent some weeks going through latex removing redundant {} to save token space, so it rather put me off spending too many tokens on trig:-)
 
@DavidCarlisle Oh, I realise we have very different requirements!
 
@RoelofSpijker Indeed. :) It will be a nice game, I want to see Ibrahimović in action. :)
@egreg: I heard that both Juve and ManUtd want a brazilian defender. :)
 
@PauloCereda Some years ago there was no Brazilian defender. :)
Teams had some just because not everybody can play offense. :)
 
@egreg Oh. :) So true. :)
 
@JosephWright Yes :). So David, to answer your question: trig has ~5 digits accuracy, l3fp has ~ 8 or 9, and l3fp-new will have ~15 or 16. Both l3fp and l3fp-new are roughly 10 to 40 times slower than trig.
 
2:04 PM
@egreg: There's a nice joke here about defensive lines. The position known in English as defensive midfielder is called meio-campo defensivo, or the popular volante. But volante is also the Brazilian word for steering wheel. When Dunga was the national team coach, people made fun of him telling that the bus with the Brazilian team would never be involved in an accident, because it was full of volantes. :P
 
@DavidCarlisle but bear in mind that I'm doing everything expandably, and parsing arbitrary expressions, with proper error checking. Not a simple register manipulation.
On the other hand, I have to admit that trig is very short.
 
@egreg: Dani Alves is one of the best in the world now though
 
@BrunoLeFloch the main effort that went into trig was looking in the literature for a short rational approximation with integer coefficients that fitted in mathchardef range, so I could keep the token count down, as long as it did that and gave reasonable accuracy on sensible values, I was happy
 
@RoelofSpijker They discovered that it's not only important to score, but also that the opponents don't. :) So now they even have good goalkeepers!
 
@PauloCereda, @RoelofSpijker, @egreg, new house rules: for every line discussing football, needs to be one discussing cricket
2
 
2:11 PM
@DavidCarlisle When I went to London for the first time, the plane was going through thick clouds; suddenly there was a clearance and so the first thing I saw in England was a cricket game.
 
@RoelofSpijker He's a fantastic player. We have nice players, but sadly Brazil lost most of its identity. There was a friendly match against Bosnia and Herzegovina a few days ago; one of the worst games I saw Brazil playing. For the upcoming World Cup, I'll go with Italy. :)
 
@DavidCarlisle And you did well. I think Rainer is somewhat responsible for making me go to lengths writing a very robust fpu. I'm responsible for forcing expandability onto myself (took me many months to figure out how to parse expressions). Four drawbacks of expandability are (1) the lack of caching (2) the lack of widthof and other box measurements (3) no random numbers (4) no one else can read my code.
 
@DavidCarlisle I've only seen a cricket game on YouTube. :( I like the raket. :P
 
@PauloCereda it's a bat. (I'm not that fond of cricket actually, but it would just break up the football focus:-)
 
@DavidCarlisle Oh my bad. :)
 
2:25 PM
@AndreyVihrov I don't agree on using \captionsenglish
 
@egreg Hmm. But I don't see any other macro to hook into in gloss-english.ldf.
@egreg Oh! I can define one!
 
@AndreyVihrov \blockextras@english and \inline@extrasenglish: Polyglossia distinguishes between extras to be applied in "big" and "small" contexts. The former applies in otherlanguage environments or after \selectlanguage, the latter in otherlanguage* or \foreignlanguage. Just say \appto and they will be created.
 
@DavidCarlisle That's a slippery slope, David. Next thing you know the^H^H^H we Canadians will want to discuss hockey.
 
@egreg Indeed, just found it. Thanks.
 
@AlanMunn Probably also tohecz (who is Czech) would like
@AndreyVihrov So you spare me writing an answer. :)
Any fan of badminton? :-P
 
2:34 PM
@egreg I once saw an official game. :)
@AlanMunn: Is badminton our "peteca"? :-|
 
@PauloCereda Cool. I've never heard of peteca. Not a high profile sport, I suspect.
 
@PauloCereda I saw a few minutes of a match: it was too much. :)
@AndreyVihrov Maybe you can suggest also \inlineextras@english, depending on the OP's needs
@AndreyVihrov Why did you set it CW?
 
@AlanMunn I've played when I was a child. :) It was common in the countryside areas. :)
 
@egreg Because I don't want to get rep from others' ideas. And as it is CW now, you can freely add the \inlineextras@english suggestion!
 
2:49 PM
@AndreyVihrov Your idea was good, it only needed a refinement.
 
@PauloCereda: Italy, really? Surely Spain is far better. So are Germany and (chauvinistically) the Netherlands :)
@PauloCereda: Not to mention the fact that Brazil is playing with a home advantage ;)
 
3:06 PM
@AlanMunn I'm sure you mean the game played on grass, with a ball?
 
@RoelofSpijker: Palmeiras wants to host one of Italy's games, so I'm in. :P
 
@PauloCereda Assuming we go to Brazil 2014. /me crossing fingers
 
My money is on Germany, unfortunately
 
@DavidCarlisle There's too much grass in England.
 
well, first the European Championship this summer, can't wait :D
 
3:12 PM
@DavidCarlisle I'm inclined to make a pun involving 'puck' right now. :-)

A: How do we Draw a Bird in LaTeX

AltermundusNo symmetry no Escher's style but ... that look like birds. First you need to save the next code in a file names bird1.pgf. It's not exactly the code given by Inskape. I export the code with latex and pstricks then I transform the code to get something lighter. %%Creator: inkscape 0.48.2 %%Pleas...

Cute birds. :)

Q: Determining which references have not been cited

David DoriaI have a very large references.bib. Throughout my document, I have used \cite{} to cite many of them. Now I would like to know if I missed any - that is, if there is a references in the bib file that has not been called using \cite{}. Is this possible?

You should really deploy that script!
 
@egreg Indeed. :)
I'll try to boost it for this week. :)
@egreg: could you point me to a case where two \bibdata fields are used?
 
4:41 PM
@PauloCereda I don't think it's possible to issue two \bibliography commands (which would write two \bibdata lines), but this can contain more than one .bib file.
 
@egreg Ah, I was thinking the opposite was also true. :)
 
@JosephWright: Could you repeat the error of the installation?
 
4:59 PM
@MarcoDaniel Oh, I've not had a look at that yet. I will do
@MarcoDaniel I'm going to have to test on Unix (I'm on Windows ATM): will be about two hours
 
@JosephWright I will wait. Thanks
 
5:22 PM
Hi.
I have a slightly daunting task, and I have to do it tonight.
Looks like it will involve using a loop in my tex document.
Can you point me to any resource which teaches me loop basics in a more or less structured way?
Everything I found on the Internet are some snippets with examples, and I don't know who does what why in these examples.
And because it really has to be done tonight, I can't go to the bookstore and get a nice big book or such :(
 
@rumtscho It depends on what kind of loop you need. An easy to use macro is provided by the pgffor package: \foreach \x in {1,2,3} {\x} will output "123".
 
@AndreyVihrov I hope I can do it with a simple foreach loop, yes.
But I don't know where to start learning about these things.
 
@rumtscho In addition to @AndreyVihrov 's comment, if the loop may involve external data, then the datatool package allows loops over a database.
 
I saw the questions here, but I can't even tell which is similar to my situation and which isn't.
@AlanMunn No, it is a small list of 16 sentences, I think I'll paste it in my document and let a macro build the layout from there
 
5:39 PM
@rumtscho One way to start is to play around with a simple case that you get working yourself and then post a question about how it could be adapted to your specific situation. (People probably won't appreciate a question without any preliminary work on your part.)
 
@AlanMunn I know. But the cases I find around are not simple, and I don't know how to build my own simple one. I am currently trying to google some kind of documentation or tutorial, but not finding anything useful.
The part about pgffor was already helpful, I got the package, but still don't know how to use it.
Actually, I found something which seems to be the official documentation for its use, but it is a .tex file and I can't compile it.
 
@rumtscho The pgffor documentation is part of the TikZ/pgf documentation. So you shouldn't need to install anything assuming you're using MikTeX or TeXLive.
 
5:54 PM
@AlanMunn MikTeX here, it is my Windows computer.
But I can't find the help.
I tried texdoc pgffor, then texdoc tkiz.
And then tried to look around for the package itself in the directories.
 
@rumtscho texdoc pgf should be good
 
tkiz -> tikz
Then look in the section called "Utilities".
 
@AndrewStacey sorry, I mistyped it here. I don't have documentation for tikz installed.
But texdoc pgf worked, now I am looking for the right place.
 
Section 56: Repeating things.
 
Yup, exactly what I found.
 
6:07 PM
@AndrewStacey: I don't suppose you recall the question where you provided a solution to the case to draw a path parallel to another path but offset slightly? I think that might help with tex.stackexchange.com/a/47020/4301.
 
@PeterGrill Do you know which question that was? (Not sure from your phrasing if you do or not.)
 
@TorbjørnT: Yep, I think that is the one. Thanks. Wish I knew how to search better here...
 
@PeterGrill I used Google ...
 
6:26 PM
@egreg: our script will be up soon. :)
 
@PauloCereda Your script :)
 
@egreg Ours. :)
 
@MarcoDaniel Cool
 
@JosephWright There are significant improvements. The optional argument of section (or other levels) can be used with a key-value syntax: \section[tocentry={Something},head={Something else}]{The section title}
 
6:47 PM
@MarcoDaniel Is the mandatory argument used for what's not specified in the optional one?
 
(In the tune of Conga) KOMA KOMA KOMA, KOMA KOMA KOMA.
I'll shut up now. :)
 
@PauloCereda Look at my comment to the OP's comment. :) tex.stackexchange.com/a/47005/4427
 
Wow, @YiannisLazarides just received a number of Question-related badges for questions that should have received this badge quite a while back: tex.stackexchange.com/users/963/yiannis-lazarides?tab=activity
What's with that delay?
 
@egreg Ah! So epic. :)
 
7:16 PM
The Heineken ads tell me to open my world. I still don't get what the heck is going on. :)
 
@egreg The value of key will be passed as an argument to markboth.
 
Anyone want to do that in TikZ?
 
7:35 PM
@JosephWright look nice -- whatever it is ;-)
 
@MarcoDaniel It's linked to some new mod tools. They are trying to visualise potential voting rings.
I'm not sure quite how it really works!
 
@JosephWright Neat!
 
@JosephWright I think it's a good practice for our gurus @Jake @AndrewStacey
 
@JosephWright Voting rings? Now I'm curious. :)
Oh my, game time! :)
 
@PauloCereda Patterns of voting, for example socketpuppets or a group or real people all of whom vote for each other
 
7:43 PM
So that's egreg in the centre, is it?
 
@PauloCereda I'm thinking Boy George.
 
@AlanMunn LOL!
 
Honestly, I can imagine Till Tantau spinning in his ... lecture hall. How is that meant to help? It looks pretty, but if you have that much data (and I'm presuming there's a lot there) then pictures aren't going to say anything. You need to do a full statistical analysis. (There was a blog post on the main SE blog a while back by a maths undergraduate that sadly showed the same failing: lots of pictures purporting to "show" something but no actual analysis.)
 
@PauloCereda Ask a question like "Show your skills" ;-)
 
@JosephWright Then I'm somewhere in there. :)
@MarcoDaniel Good idea. :)
Now, game time! :)
 
7:46 PM
@PauloCereda ;-)
 
@AndrewStacey That was the inspiration for the real images (which seem to be less complicated). I can't really say, as I thought the new tool was bust: we don't get any hits at all!
 
@AndrewStacey Data visualization as a tool for understanding large amounts of data is useful. It is not a replacement for an analysis of the data.
Not that I'm saying that this particular case works, I don't have enough info to decide.
 
@AlanMunn Real image coming up
(Not from our site - a screenshot by a mod on one of the big sites)
 
@JosephWright So Purple guy and Blue guy hate each other, but they all like red guy a lot.
 
@AlanMunn Red guy is the 'puppetmaster', and the others are all 'socks'
I think, anyway :-)
 
7:54 PM
@JosephWright So it the Red guy the one to whom the 25% of the others' votes went? Or is that person not in the graph?
 
@AlanMunn Other votes?
 
@JosephWright I.e. Purple, Green, Blue, Olive's votes.
 
To be honest, as I've not seen this live (with some numbers) I'm not actually sure how it works :-)
I just thought the drawings were fun
 
One thing that is likely is that there's a correlation between vote reciprocity and chat participation. But that's a very tiny percentage of users.
 
@AlanMunn Yup
 
8:01 PM
Does anyone know why tikz in the last stable version is only available via tlcontrib?
 
@MarcoDaniel Makefile should now be fixed in the SVN
 
@JosephWright Thanks. Was there an error?
 
@MarcoDaniel Yup: I'd forgotten to remove an entry from the Makefile in l3trial
 
@JosephWright I tested and it works ;-). Thanks
 
Does anyone have advice for a hyperref colour that doesn't look terrible when printed out? I like the visual clue that you can click something, but then when I print it in B&W it looks fuzzy.
I'm using Blue right now, text colour, not box.
 
8:15 PM
@Canageek Browse the contents of the xcolor documentation.
 
@Werner I now have the means to use any colour I can think of. I still have no idea what colour to use.
 
If you want a nice diagram to look at, here's one that's about as meaningful as the ones above. (Incidentally, I agree that data visualisation can tell you where to look and as such is very useful, but I worry that the SE people will use it to figure out what they are looking at for which one needs proper tools).
 
@JosephWright How many upvotes will I lose this time? I vote for David's answers, who votes for Frank, who votes for Werner, who votes for Paulo^H^H^H^H^H [oh, no, this is impossible :)] me. A blatant voting ring. :)
 
@egreg You have too much reputation to punish that way: Now you must stare at an interesting TeX problem without being allowed to work on it for 5 min. :D
 
Hi again!
 
8:24 PM
@egreg The vote ring tools are looking for high percentages, so provided you also vote for other people you're fine
@Szabolcs Hello
 
@JosephWright Has there been any further communication on egreg's situation?
 
Is it possible to have a page, with only a single captioned figure on it, rotated 90 degrees? The figure has a wide aspect ratio, and fits better rotated. I want the caption rotated as well. But I'm interested only if there's a simple way, otherwise I'll find another solution (without rotating it).
 
@AndrewStacey No, I know nothing special
 
@Szabolcs Package rotating and sidewaystable environment
 
@Szabolcs I just use paint.net to rotate the figure, then \includegraphics[height=0.9\textheight]{NOESYcAMP-I636D.png} to insert the figure
Oh, there is a package to rotate things? That does sound easier >.>
 
8:27 PM
@egreg sidewaysfigure perhaps, as it was a figure.
 
@TorbjørnT Yes, of course!
 
@Canageek Also, I have vector figures and I need the caption rotated too, so I'm looking at the package
@egreg @TorbjørnT Thanks!
 
@Szabolcs I tried using vector figures in LaTeX once, discovered I had to do a multistep procedure to convert them from svg to pdf, and that the text wouldn't resize along with the figure and gave up and used png from then on.
 
Hm, almost every program I use will export EPS/PDF, I never needed SVG.
 
@Szabolcs I dislike using PDF for images; It is a page-display file-format, not an image file format. SVG also works on the web and in every other program, whereas PDFs need external programs and are rather iffy to edit in vector graphics programs.
Using PDF for vector graphics is like putting an image file inside a word document before emailing it to someone. It works, but there are far, far better ways to do it.
 
8:36 PM
Well, it sounds like you don't have much experience with vector graphics ;-)
Got to get back to work
bye
 
Wow, Arsenal 3:0 Milan, first half. :)
 
Bye
No, I have very, very little. I like the idea of vector graphics, but the tools just aren't as good; I can do things much faster in say Paint.net then I can in inkscape.
 
@PauloCereda The aggregate is still 3:4.
 
@egreg Yes. :) Tough game for Milan. :)
 
Huh, I have \usepackage[margin= 2 cm]{geometry} set, but the distance from the top of the page to the top of my text is closer to 2.5 cm then 2.
Stupid Adobe reprints
Ok, now just the bottom of the page is causing a problem; probably due to the page numbering...
How do I get the distance from the bottom of the last paragraph to the bottom of the page to be 2 cm?
Errr, anyone? This is kinda important as I was given really specific instructions (2 cm margins on all sides) and that it must fit on one page; an extra 0.5 cm should be enough to fit everything. How do I get the bottom margin to work?
 
8:50 PM
Just to check the obvious: you're using the right paper size, right?
 
\documentclass[letterpaper,12pt]{article}
@DavidZaslavsky I assume so; I've loaded the printer with letter and set letter in my header.
