@cmhughes Maybe it is my browser but the old image does not disappear fast enough so sometimes I see parts of it when the new one is supposed to be seen. Specifically, this is the 2 on the right.

1:46 AM
@PauloCereda I updated the answer of the CV using your images. Thank you very much!

Anyone else have a problem compiling:
\documentclass{article}

% Both of these are require to duplicate the problem
\usepackage{pgfplots}
\usepackage[splitindex]{imakeidx}

\begin{document}
\end{document}
With the above I am getting:
Undefined control sequence.
l.44   \ifnum\luatexversion
<68
And this with an updated TeXLive2012 as of today as per Extraneous text from \NewDocumentEnvironment (corrupted TeXLive2012 ?)

2 hours later…
4:03 AM
@PeterGrill compiles fine for me on TL2012. Haven't run tlmgr recently though

user19161
@cmhughes What did you use to create it?

@WillHunting the following
\documentclass{beamer}
\usepackage{graphicx}
\usepackage{pgfplots}

\usepackage[active,tightpage]{preview}
\PreviewEnvironment{tikzpicture}

\begin{document}

\begin{frame}[fragile]{}
\begin{center}

user19161
@cmhughes I wonder why the image is not perfect...

@WillHunting me too

user19161
4:22 AM
@cmhughes But I must say the picture looks quite terrible.

@WillHunting the picture, or the animation?

user19161
@cmhughes OK I think just the animation. Does not feel like an animation to me. Perhaps more frames are needed.

@WillHunting it's never going to win any awards- it was just for fun :)

user19161
@cmhughes OK. :-) It must have taken very long to compile if you did not use gnuplot.

7:34 AM
@PeterGrill See the same here on an up to date TL2012

8:06 AM
@PeterGrill It also quits with the same error on up-to-date MikTeX 2.9

@DavidCarlisle lol epic fail!

9:09 AM
@DavidCarlisle As you are working on margin stuff again, may I ask how the package based on this answer is coming along?
@DavidCarlisle Incidentally, very neat idea to write your messages to a length which exactly fits the size of a starred message. Really convenient!

9:36 AM
@StephanLehmke well not really working, As may be seen by the fact that it casually trashed \fbox that was just a 5 minute answer thrown at that question. But I haven't forgotten the other one...

@PeterGrill Yes, for some reason pgfplots leaves \directlua defined and imakeidx is fooled. I'll send a fix as soon as possible; changing the loading order should suffice, though.

@PauloCereda: couldn't you use github's font?

@ℝaphink It was late in the night, so I used bruteforce. :) But your idea is great. :)

there's UTF+f209
and UTF+f208
where did you get the linkedin logo?

I... drew it. :)

tikz?

10:15 AM
Actually, in Inkscape. :) The LinkedIn logo uses Myriad Pro Bold, but in a different width scale.
And I fail a lot with TikZ. :)

hehe
so you have a pdf?

Yep. :)

do you have it somewhere? :-)

I'll upload it to a code bucket repo I have in GitHub. :) It's where I put my random stuff. :)

ok :)

10:18 AM
I knew they introduced a font, but I never tried it myself.

well you're using it

thanks

My pleasure. :)

@egreg: I'm lazy ;-)
otherwise I would do it this way indeed

@ℝaphink \fontspec is slow, it's better to declare a font beforehand. You need to move the brace before \char to be in front of \fontspec

herrm
vim-latex has decided it wants me to use  everytime I type "

how can I circumvent this?

10:44 AM
Hey Will
Thanks for help me that other day =)

user19161
@paulo openSUSE 12.2 does not even come with Rhythmbox preinstalled!

@WillHunting Really?! I'd cry. :( What's the default player?

user19161
@N3buchadnezzar No problem, just pray that my three wishes will come true in return (they are secret though)! :-)

@ℝaphink With Emacs I just type " twice to get a straight double quote. Otherwise it inserts  or '' depending on the context

user19161
@PauloCereda Only Totem is preinstalled, very weird.

10:46 AM
@WillHunting Weird indeed.
How's the distro so far?

user19161
@egreg I like to use \lq and \rq instead.

user19161
@PauloCereda Nothing special, I just can't resist to try any of the major releases.

@WillHunting hehe I know that feeling. :)

Will Hunting will hunt for new releases? =)

11:11 AM
@egreg and I was trying really hard not to answer a vim question with "use emacs"

@DavidCarlisle LOL

@DavidCarlisle Did I suggest switching? ;-)

@egreg Aquamacs and MacVim >> emacs and vim. :)

11:37 AM
@PauloCereda I thought this may get you to move to Europe: what-if.xkcd.com/10

@DavidCarlisle ooh so new São Paulo will be like England. :D

user19161
What's the big deal with Emacs? All the gurus seem to use it.

@WillHunting Nothing really, it's just The One True Editor, and we don't talk to people who use lesser systems.
2

I'm a sysadmin, so I use vim
Emacs is an OS, and I already use one.

:-)

11:42 AM
Especially we don't talk to people who use vi(m) :-)

I have enough friends I don't need a user-friendly computer

user19161
@ℝaphink Can you explain the joke to me? I don't get it. Is it because it is so full of features that it is like an OS?

@WillHunting If you like the text adventure games from the 80s yes it's an OS

user19161
@percusse Erm, still don't get it...

@WillHunting some people think an editor should mainly be for editing files, emacs is powerful enough to write (and includes by default) email programs symbolic calculators, newsreaders, (had a web browser at one time not enabled by default) it is basically a lisp engine with some editing features as lisp primitives

11:47 AM
It's for the people who are connected to the keyboard and don't know what a mouse click is. You can practically do everything within Emacs provided that somebody add some lisp directive.

user19161
@DavidCarlisle Ah, so my guess is quite right!

user19161
@percusse Still, it is hard to navigate without a mouse.

It's painful and innefficient to use a mouse
:-)

@WillHunting you really don't need a mouse in emacs.

or in vim ;-)

11:48 AM
Don't mention it to Emacs people, I'm sure there is a shortcut for navigate this page

@DavidCarlisle <3

@WillHunting: I'm convinced Richard Stallman always meant the GNU OS to be GNU Hurd with Emacs on top and nothing else.

@DavidCarlisle: can we write an emacs clone within emacs? emacsception. :)

One of the first things I installed on my android tabled was an ssh client so I could ssh in to work and use emacs. But the terminal emacs then has no mouse (or touch) support (and the tablet has no mouse) but emacs works fine.
@PauloCereda Not tried that but I have tried running emacs in an emacs terminal buffer. It works but it does mess with your head slightly

@DavidCarlisle It sounds like when Brent suggested an arara rule for running arara within an arara run. Of course, if the underlying arara run was running on top the very same .tex file containing the very same call to another arara run, we would enter a lovely infinte loop with lots of noisy birds spawning. :D

11:54 AM
@PauloCereda More like that Lady Gaga song with lots of ra ras

@PauloCereda: trying to make the linkedin logo
using Myriad pro bold is quite easy
it's the rounded box around it that's a bit tricky, but I'm sure it's not too hard
how can I make a rounded box around just two characters?

@ℝaphink It is. :) You just need to stretch it a little. :)
Oh I don't know. :(

12:14 PM
it looks ok for me without stretching

12:32 PM
@PauloCereda: trying with tikz now
\begin{tikzpicture}
\node[fill=color2,rounded corners=2pt] {
};
\end{tikzpicture}}
the alignment with the text is not great

@ℝaphink Very nice! Try the baseline option in the tikzpicture, something like \begin{tikzpicture}[baseline=-0.65ex]...

@ℝaphink You could add [baseline] to the tikzpicture and anchor=base to the node (instead of manually trying to find the right offset).

1.1 does it
ah
@Jake: with baseline=0 and anchor=base, it looks good
the text in the logo is aligned with the text outside :-)

@ℝaphink Cool. baseline=0 and baseline are equivalent though, I think

right, just tried it :-)

12:45 PM
@ℝaphink Mmmh, very nice! Probably decrease the size of the LinkedIn logo a little bit, though?

some size option for tikzpicture?

@Jake My thoughts exactly. :)
@ℝaphink scale=0.5
probably. :)

that's what I tired
tried

@ℝaphink Or just don't use \large

but it doesn't do anything

12:46 PM
Wait a minute, WHERE'S THE HAT?!

hehe

I used large for the test :-)
@PauloCereda: I changed my "pro" picture recently with one taken at a wedding :-)

@ℝaphink ah. :)

@ℝaphink You'll need to add transform shape to the node if you want the scale parameter to apply.

12:47 PM
without \large

When everything fails, \scalebox?
:)
Wow, I'm in a bruteforce mood today. :D

still too big?

@ℝaphink I'm afraid so. :(

ah
\small ?

IMHO it would be nice if the whole tikzpicture could have the same height of the octicon.

12:51 PM
right
it would have to be scaled to 1em roughly

so...
\scalebox

1:13 PM
@egreg: as promised, the book. :)

user19161
@PauloCereda You study that?

@WillHunting I had some fun with Lambda Calculus in the past. :)
Can't remember a thing nowadays. :P

user19161
@PauloCereda I only had fun with calculus and lambda, not lambda calculus.

@PauloCereda I don't have it. But I have Lang's "Algebra". :)

@WillHunting :)

user19161
1:15 PM
@egreg I have that too, not my cup of tea. I prefer Cohn's 3 volumes...

@egreg Really?! That book is awesome. :)

user19161
@PauloCereda I only like the Galois theory chapters.

@WillHunting I've those in my office. Actually my beloved algebra book is Jacobson's "Basic Algebra" (two volumes).
@WillHunting That's very well written indeed.

user19161
@egreg Ah, now a cheap Dover publication. Unfortunately it does not contain linear algebra, otherwise I would switch to it. The older 3 volumes treat linear algebra though.

@egreg ooh those are the algebra reference books. :)

user19161
1:23 PM
Knapp now has two volumes of Algebra, going all the way up to AG and ANT but omitting many theorems it seems.

user19161

2:01 PM
@PauloCereda I don't know. You copy-paste a load of stuff to write the script system for LaTeX3 and suddenly you're the shell script expert :-)

@JosephWright :)
I had no chemistry book, sorry. :P

Is it OK to make the GitHub repository private but still allow other people to see it with a link (if possible) without forcing them to register on GitHub? Context: me and my supervisors to check the progress ( I highly doubt that they ever will but nevermind)
it's now on public and I'm fine with it but one of the supervisors believes in all conspiracy theories including somebody reading and stealing my work
I would actually be half-happy knowing somebody found my stuff let alone read it :)

@percusse A feeling of most students I think ;)
(including me of course)

@JosephWright (change of subject) What I keep wondering about: Have there been any performance tests yet for LaTeX3? 10 years ago when I was a bit more active there seemed to be a tendency to keep kernel and base stuff relatively lightweight wrt. computational effort, without doubt caused by the restrictions especially on memory parameters at that time.
Nowadays, the mere existence of TikZ seems to have caused a certain amount of corruption...

@StephanLehmke Requirements have certainly shifted
@StephanLehmke We do worry about performance, but not in the same way as for the LaTeX2e kernel

2:10 PM
Have there been tests running "substantial" documents under LaTeX3 and comparing performance with LaTeX2?

@StephanLehmke And performance problems still apply, mostly wrt to speed (not to memory). I know I'm not the only one who have slow PC.

@StephanLehmke For example, we are happy and indeed encourage using long descriptive command names. We do worry about performance in tight loops, and Bruno in particular has really worked on this recently.

@tohecz You have not worked on a Sun ELC with several X terminals attached, and neither on an Atari St, I assume ;-)

@StephanLehmke Can't really be done easily, as what we have in the main is some tools, not a full document preparation system.

@StephanLehmke No, I've not ;)

2:13 PM
I've done tests on some areas. For example, we use macros not toks for storage: there is hit here, but it's small enough we decided it was OK. If you want to really test out LaTeX3 performance-wise then xor is probably the place to look.

@tohecz I had 45min generating time for my thesis, just because I had defined some inefficient math symbols. Using PicTeX could make a document take hours to compile.

@StephanLehmke The biggest issue I'm aware of is siunitx plus xfrac plus microtype, but that is I think to do with the NFSS and not us :-)
I did speed test siunitx a lot when writing v2. The LaTeX3 implementation is faster than the old LaTeX2e/TeX one, but that is probably attributable to my poor loop writing in v1 as much as anything else
@StephanLehmke What I can say is people use siunitx and fontspec routinely, and those are big packages. There's no bigger issue than doing complex TikZ stuff.
We've had complaints that LaTeX3 coding can never be more efficient than hand-crafted raw TeX. That's true, and if you want ultimate performance you need to write everything yourself. However, the problem is that getting it right in all cases is hard. So LaTeX3 kernel programming is meant to give us general tools that work for everyone, even if we do loose some performance.

@JosephWright Ok, nice to hear. I was worried more about stacking so many syntactic/semantic layers the system would spend most of its time handling layer interfaces.

BTW, a captious question: will ever biber and makeindex and similar be written in TeX so that you don't need to run any external program for your document?

@StephanLehmke As I say, there is a hit

2:20 PM
Anyone want to give it a try?

@StephanLehmke Case study: tex.stackexchange.com/questions/69870. Bruno's asked this question at least in part as our 'leave the head' function has some issues at present. We're deciding whether to use an updated concept he has in that question, or stick with the one we have. There is a performance tradeoff
@BrunoLeFloch Is also worrying about using \pdfstrcmp, as the way that is implemented in LuaTeX (using Lua) is rather slow. It's OK for pdfTeX and XeTeX.

@JosephWright Well document performance is not only about performance of a single function but also how they interact. NFSS for instace is not a problem in itself when looking at a single font switch, but it can really slow down a document when for instance there are several switches into and out of math mode in the definition of a single math symbol.

@PauloCereda Definitely

@StephanLehmke Yes: that's at least in part why there is an issue with siunitx in some cases (lots of font switching). Only shows up badly in really long tables :-)

After fighting with TeX4HT, I'm more than willing to try that

2:26 PM
@ℝaphink :)

@StephanLehmke Also, expectations have changed. If documents are not output at more than a couple of pages per second, people don't like it :-)

it fails quite badly with fonts for me

@ℝaphink i used it before to convert TeX to MSWord (for a language editor to make corrections), I was quite happy with it

@tohecz: you used what?

@JosephWright Well with the "lightweightedness" of a 90's LaTeX system, hardware development has brought it about. While TeX is immune to Wirth's Law, package writers seem to aim at making up for it lately...

2:33 PM
@ℝaphink tex4ht

@ℝaphink damn, sorry then

no problem. I'm using TeX4HT to produce ebooks currently.

@StephanLehmke We are not in a bad position if @BrunoLeFloch can write an expandable IEEE854 floating point unit in TeX and it doesn't kill everything!

@JosephWright Thats exactly what I was wondering about. When it is available, people will use it for stuff. I wonder how long the average larger LaTeX3 document will take to compile.

2:36 PM
Xavier is reviewing moderncv questions, apparently :)

@PauloCereda: the PPA version is too old and broken

@StephanLehmke The LaTeX3 FPU is not bad performance-wise: Bruno says broadly similar to pgfmath, which is used a lot inside TikZ. We only need the FPU for rotating boxes, so that is not exactly common.

@ℝaphink oops, build from sources. :)

that's what I'm doing
there, just built
the cmake file is incomplete

d'oh

2:43 PM
quite impressive
not perfect at all
but quite good

cool!

it's failing quite bad on my files
it puts the whole text in small caps

yay, new layout! :P

let me show you
converted from the PDF directly
there's a few bugs where it adds small caps for no reason

I see.

2:48 PM
but otherwise, it's pretty close to what crocodoc does
and even the fonts are there

Overall, it's very nice though.

even the github logo which is a font
the fonts are actually embedded in the html
with src:url('data:font/truetype;base64,FOOBAARRRR');format("truetype");
ebook-convert doesn't seem to like it at all on the other hand
btw @PauloCereda, I ended up using a \scalebox: cv.raphink.info

@ℝaphink It's looking very nice! :D

thanks
which is to add footnotes for projects I develop/contribute to
using symbols and multiple footnotemarks to the same note
haha, the funny thing now is that you can actually copy the "in" in the linkedin logo :-)

@ℝaphink Easter egg. :D

3:00 PM

@PauloCereda Did you see latex-project.org/latex3.html?

4:33 PM
I now have 1k messages in this room, yay!

@WillHunting Congrats! :)

@JosephWright hi there! here's another one that I think has been closed for the wrong reason tex.stackexchange.com/questions/70300/…

@cmhughes What would you choose?

if we're going to close every question that asks for help producing a specific formula then it will reduce the number of questions on the site by quite a lot

@WillHunting gow do you find out?

4:38 PM
@cmhughes Perhaps, but normally you want some generality ('How do I reproduce feature X?')

user19161
@DavidCarlisle From my chat profile when I am in the room. chat.stackexchange.com/users/19161/will-hunting. Look for the room under "currently in" and the small number on the bottom right.

@JosephWright I actually should re-phrase: I personally don't think it should have been closed

@cmhughes That's what voting is for: other people clearly did. It does not have the 'generality' part at all: there are lot's of 'please draw this for me' questions we also close

@WillHunting I didn't know I had a chat profile:-) (2855) (well 2856 now I suppose:-)

Simply asking how to reproduce an arbitrary equation with no code or particular difficulty highlighted is 'not likely to be of use to others'

4:42 PM
@JosephWright fair enough; it's honestly not a big deal to me. how is it different from tex.stackexchange.com/questions/70423/… I'm asking not to try and argue, but simply to understand :)

@JosephWright That's not clear;y the case, it's not so different from other "example" pages that just list some random examples and how to achieve them. People don't want that equation but they might want some kind of fraction with a sum and a side condition with a bit of white space

@DavidCarlisle I agree.

@cmhughes This second question is more general, as written
It's always tricky: sometimes the question does have some form of general element, sometimes it's hard to be sure
@cmhughes This one seems to be about a type of output, not a specific example, at least as I read it

@JosephWright once an answer has been given/accepted what affect does closing actually have? (sorry for showing ignorance:-)

@DavidCarlisle Not that much really :-)

4:49 PM
@JosephWright ok. I think it's a very fine line though. At least the OP in the first question showed a really good attempt at producing the output; the OP in the second question didn't show anything. Still, that's the beauty of a community-based site :)

@cmhughes If the first question had said something like 'I want to reproduce [graphic], but can't work out how to handle [general feature]' it would be fine, I think
We have the same problem with graphics questions: are they 'draw this for me' or 'how do you tackle this general issue'

@JosephWright ok, thanks a lot for clarifying :)

@cmhughes Would probably make a good meta question: it's not an easy line and it would be good to have some clear guidelines we can refer to

@JosephWright good idea. I thought that your blog post was very good tex.blogoverflow.com/2012/08/maintaining-a-balance There are definitely questions that I think should be closed, but sometimes it happens far too quickly

@cmhughes Sometimes. I'm happiest when there is a comment followed by a delay. Often the original poster comes back agreeing, so we can then 'tidy up' without feeling we've risked putting anyone off.

5:01 PM
@JosephWright yes, I think that's the ideal situation. If I was a new user and my question got closed very quickly with no confirmation from me, I would be somewhat put off. It seems like it creates something of a wrong impression, and might be perceived as unwelcoming

I think I've asked this before but anybody knows a website where people bash PHP? I've gathered some data and arranged an SQL database. I would like to publish a website for myself and I'd prefer the last-known-cool-toy around if PHP is not the favorite son anymore.

5:14 PM

Here is a TeXnicCenter-specific solution which will hopefully seem sound enough to the people claiming it's bad practice to have one single, huge repository for all LaTeX auxiliary files (which it probably is). On the Build->Define Output Profiles menu, choose your standard build profile (say,...

I'm afraid this answer is already written, after all it's not TeXnicCenter-specific, it's MiKTeX. :)

@PauloCereda Hi, Paulo! Do you remember the complete convert instruction that @GarbageCollector gave once, to turn a series of frames into a .gif animation? I wrote it down in a piece of paper which (obviously) now I can't find.

@PauloCereda I assume that you like it :) But I'm getting confused whenever I read stuff on SO or other geek corners.

See my comment :P

@percusse awwww. :)
@percusse: retag that question to include the tag. :P

@PauloCereda I think your comment is not entirely correct under the sprite sheet blog post. \pgfdeclareimage and \pgfuseimage does that for you and I'm pretty sure there is a way to tell graphicx to use the image once.
So your blog post is still great! :D

@percusse You are right. :) Stefan mentioned he analyzed the output and it seems the image is only used once.
Actually, my bad, it is used more than once, but it doesn't bloat the size.

@PauloCereda Just tested your sprite demo, and noticed including the image several times doesn't bloat the output size much

So duck tag is great idea and I want to understand if PHP is not good to play with what is?
Wow I'm using a few \expandafters in my brain to answer your questions :)

@percusse hm?

@egreg: Your holidays were too long this year ;-)

@MarcoDaniel Never too long. :)

@PauloCereda I'll try to see what happens with that PGF version.

@percusse You are my hero. <3

@egreg Indeed ;-)

@egreg Thanks! This simplified things even more. That particular command is now complete, and has saved an enormous amount of typing and made the documents a lot more readable. yay.

@MarcoDaniel Now that iPad can TeX, wait for egreg to pwn us all during the holidays. :) All of his 10+ uvpvoted answers will have the ubiquous Inviato dal mio iPad. :)

@PauloCereda I'd be able to answer during lectures and, most importantly, when biking. :)

@egreg "bike computer" ;-) -- velocity , km and TeX ;-)
@PauloCereda send from my iPad ;-)

@egreg Oh! :)
@MarcoDaniel When I get my iPad, I'll customize the signature message to "Sent from my iToaster". :)

@PauloCereda LOL

@PauloCereda Be afraid when seeing a big scooter with an iPad mounted on the handlebar.

@egreg We could adapt Apple's Dictation to recognize TeX commands, so pedestrians would be safe. :)
Though I got some unexpected results with Dictation:

I said "This is a great feature". Dictation got: Jesus be a great feature.
