@percusse then what would be a good choice for a sans math font for beamer presentation, where readability is important, that is pairing with helvetica?

6:08 AM

@PauloCereda @ChristianHupfer What about arara? That's a portuguese word.

Christian Hupfer

6:37 AM

@Johannes_B: Thanks for information... Now I know two words in Portuguese

@ChristianHupfer dummies.com/how-to/content/…

Christian Hupfer

@Johannes_B: ;-)

@ChristianHupfer Sag mir quando, sag mir wann

@ChristianHupfer seems like you hacked my brain.

Christian Hupfer

@Johannes_B: How could I do that? :D

@ChristianHupfer you made me use google, find the page, and suddenly vvvvv

Christian Hupfer

6:45 AM

@Johannes_B: You are easy to distract ;-)

Break the silence ...

I got a quick meta question. The asking user of this question has found the solution himself and made a comment. http://tex.stackexchange.com/q/197297/60603
Do you think one should encourage him formulate answer?

Christian Hupfer

@Harald: You could do that, but you should do it quickly, because I voted for close ;-)

Well, the question itself is maybe not brilliantly formulated anyway...

Christian Hupfer

@Harald: That's the cause of my vote ;-)

:) ok, thanks for the feedback

9:38 AM

@Harald It's just good to use the custom off-topic comment and explain what's up

@tohecz the "custom off-topic comment"? Is that a documented feature?

@tohecz something like [help/on-topic]

10:07 AM

@Johannes_B Indeed. :)

Christian Hupfer

@PauloCereda: Hell' ;-)

@ChristianHupfer o.O I think you are not suppressing the correct part. :P

And hello! :)

Christian Hupfer

@PauloCereda: N' Paul', my ' hangs 'n my keyb'ard :-P

@ChristianHupfer There's an o on the loose, apparently. :)

Christian Hupfer

@PauloCereda: If there w'uld n't be aut'c'mplete I c'uld n't even write t' y'u ;-)

10:18 AM

@ChristianHupfer :)

Christian Hupfer

@PauloCereda: I got the cause... I remove the Eisbein that fell between the 'o' and some other key ;-)

@ChristianHupfer Great, anger management. :P

hello guys :)

@izabera Buongiorno! :)

^^

back from the deads... i mean the seaside

10:34 AM

@izabera cool! :)

Christian Hupfer

\begin{being_occupied...}....

@tohecz: I posted a question on AskFedora. I'm trying to control myself, it's very different from other cool communities like ours. :)

@ChristianHupfer xpatch it. :)

@Harald I'm not sure how's it if you don't have so much rep. When you close a question, there's a large tree of closure reasons. In the off-topic branch of this tree, you have an option to write a custom comment

10:51 AM

@tohecz LOL the best one. :)

11:05 AM

where can i find a list of the packages included in the ubuntu software center's texlive version?

it's only 236 MB

and it's from texlive 2013

@izabera It's a lot of work for Norbert to re-package TL for Debian, then more for it to get picked up by Ubuntu

@izabera I don't know, but I do know one thing: you don't want that version of TL

lol

i was just curious

@tohecz s/TL/Ubuntu/g

just install a vanilla TL from tug.org

11:07 AM

@tohecz hmmm vanilla. :)

@tohecz ah, ok. I can't even see close votes, yet.

@PauloCereda I gave my sister a vanilla rhum and she hasn't opened it yet :-/

@tohecz oh. :(

this one: eshop.interdrinks.cz/deploy/img/products/1360/1360.jpg but needed to say, they don't drink spirits at all, I just thought that they ought to have a good bottle at home, just in case :)

@tohecz Emergency drink, as I call it. :)

11:15 AM

@PauloCereda yep, something like that :)

@tohecz ahem

@DavidCarlisle :)

@tohecz: ask.fedoraproject.org/en/question/52434 I must be strong. :) See comments. :)

@PauloCereda would "I have no problem with windows printer drivers" be an acceptable answer?

@DavidCarlisle any problem? :)

@DavidCarlisle LOL Do not tell me you intend to harvest karma (the heck is wrong with those people? :P) there as well. :)

Congratulations, you have received a badge 'Student'. Check out your profile.

woohoo

11:29 AM

I know this is not what this site is usually used for, but I was wondering if we could harness the raw TikZ power here to make figures for the new evolve user guide.

evolution.experimentalworks.net/doc/user-guide.html

I count 26 figures.

Any mercurial users here?

No, actually 12 on that page

More elsewhere probably

11:49 AM

(from a song: I smile like Spock at the mirror ... the ticket controll is after me, but Bolt is not my figure.) I love that band (unfortunately it's Czech)

@FaheemMitha I think really you want picture mode to give the images that more professional look than the standard TiKz fare:

34

A: Draw an aircraft with Tikz

It was suggested in chat http://chat.stackexchange.com/transcript/message/9482087#9482087 That picture mode would be the ideal tool for the job here: \documentclass{article} \begin{document} \begin{picture}(200,100) \put(30,40){\line(1,0){150}} \put(30,40){\line(0,1){60}} \put(30,100){\line(...

12:07 PM

@DavidCarlisle Not sure I follow. You are suggesting not using TikZ?

Picture mode is the traditional drawing tool?

The pictures aren't that complicated, though

Could be handled with the usual tools. matrix and stuff

I'm actually a bit confused about which figures are current. Maybe I should add that to the question

@FaheemMitha @David is only teasing you I think. IMHO TikZ is a pefrect tool for diagrams of this kind, because it allows you not to care about the positioning.

@PaulGessler True, any suitable program/language could be used, but I am suggesting TikZ, which I think is the best. Only the best for Mercurial. — Faheem Mitha 13 secs ago

Apparently Paul is not convinced.

@DavidCarlisle i think I jumped the gun a bit here. I'm not actually sure which figures are being used in the guide.

Probably need to clarify that first.

Checking with Pierre-Yves now.

12:50 PM

@FaheemMitha as @tohecz says my aircraft reference was a tease (unless you are as impressed with that picture as @PauloCereda was:-) that said, I'm not sure tikz is the right tool either: if the rest of the document isn't being done in tex using tikz for those images seems massive overkill (are you sure the maintainers would accept that, or are you one of the maintainers?) hand writing svg (or at least producing simple svg somehow) would seem a better fit.

@DavidCarlisle gotta love that plane. :)

@FaheemMitha the existing svg is produced with inkscape which is quite a reputable vector drawing tool, are you really sure that tikz diagrams will be more maintainable in this context?

@DavidCarlisle No, I don't know if the maintainers would accept it. I just wrote to the mercurial devel list. Presumably they'll let me know.

@DavidCarlisle Well, I certainly prefer TikZ over inkscape, but I can't speak for the maintainers.

The document uses rest, it looks like.

I'm not really fond of gui tools, personally.

If they won't accept it, there is no point in pursuing it, of course.

@DavidCarlisle How did you query the drawings to find out the inkscape thing?

BTW, anyone here actually using mercurial?

@FaheemMitha Yes

@JosephWright Hi. How are you?

1:02 PM

@FaheemMitha I'm fine

@FaheemMitha view source in the browser menu 

@FaheemMitha "inkscape:version="0.48.4 r9939""

Ah, ok.

right click on image, open in new tab (or your browser's eqivalent) look at source

@DavidCarlisle yes, they might not be willing to do the TeX thing. I realise not everyone is enthusiastic about TeX.

1:03 PM

oops, sorry for double post

But isn't TikZ trying to be backward compatible? I use it myself. Am I going to have to rewrite the source periodically? I hope not.

@FaheemMitha you should check that before asking people to put time into recreating the figures in tikz:-)

@DavidCarlisle Yes, I jumped the gun a bit there. Shall I delete the question?

@FaheemMitha It's not compatible with people who don't use tikz. If I was documenting some software and someone offered me some images for the document I wouldn't accept them unless I could recreate and/or update them as the software evolved.

@DavidCarlisle No, I meant, will TikZ sources continue to work, like TeX/LaTeX itself does?

1:06 PM

@FaheemMitha it depends ypu could leave it as a "tikz showcase" question but you should make it clear that they may not be used....

in the future.

@FaheemMitha possibly, possibly not (that is never guaranteed) but that isn't the main concern here I think.

@DavidCarlisle Um, so what should I do at the moment. Add a note at the bottom saying I am waiting for clarification by the maintainers?

@FaheemMitha no idea:-)

@DavidCarlisle ok.

1:11 PM

@FaheemMitha The diagrams are quite nice IMHO. Personally, I think if they are fine with their current scheme, there's no need of changing it. :)

@PauloCereda ok

Could TikZ produce comparable diagrams to these, though? Without great difficulty?

@FaheemMitha My dad would certainly have a terrible time trying to produce these diagrams. :)

@PauloCereda as would I, I have never managed to make tikz make so much as a line...

@PauloCereda Is your dad an engineer?

@FaheemMitha He's safe: an accountant. :)

1:20 PM

@DavidCarlisle i added a note. If they say no, I'm not sure whether I'll delete it or not.

@PauloCereda oh

@DavidCarlisle btw, your airplane is very Zen. I believe that is the preferred term.

@FaheemMitha s/Zen/rubbish/ :-)

@DavidCarlisle You honour RAF, sir. We salute you. :)

@PauloCereda RAF?

You mean the Royal Air Force?

@FaheemMitha Yep. :)

@DavidCarlisle: youtube.com/watch?v=8sG1ibc9Hvc :)

@PauloCereda hmm bill bailey, daren't turn the sound on for that at work...

1:28 PM

@DavidCarlisle LOL I understand. :)

Anyone up for a brain teaser? vvv

Q: Insert footer on chapter page but NOT header

this may or may not seem to be a weird thing to want, but I would like to have a customized header on all my pages, except the first one of each chapter, ToC, ..... Furthermore, I would like to have a footer in form of a simple line above the page number on each and every page, even on the first...

header-footer chapters fancyhdr

why do people put one warning in the title and question and then make an example that doesn't make that warning but a different one, and accept an answer that fixes the example without addressing the question? (not that I blame dalief:-)

Q: Underfull \hbox (badness 10000)

I have multiple tables which look like this: \begin{tabularx}{\textwidth}{|l|X|l|} \hline \textbf{ID} & \textbf{Description} \\ \hline 336858 & The description \\ \hline \end{tabularx} and I get for each one the warning: Underfull \hbox (badness 10000) in paragraph at lines X--Y As I un...

@DavidCarlisle No idea: they just want the 'errors to go away' ususally

@PauloCereda That's funny.

Christian Hupfer

@PauloCereda: \end{being occupied}....

1:40 PM

@ChristianHupfer :)

@tohecz i've seen your posts on academia.

Mind if I ask what happened with academia.stackexchange.com/q/26228/285 ?

@FaheemMitha it's accepted now

@tohecz Ok. Did you "work more on the essay"? :-)

Weird comment, but sometimes academic reviewers can be wacko.

@JosephWright have you given evolve a try?

@FaheemMitha well, yes, somehow. We re-read the article, removed some paragraphs, split a lemma into two, added a figure, etc. I was accepted so quickly then that I suppose the referee didn't even intend to see it again.

My department was offering a crash course on LaTex (sic). Guess if I signed in. :)

Christian Hupfer

2:01 PM

@PauloCereda: Then you will be the Crash course Crusher? ;-)

@FaheemMitha What's that?

@ChristianHupfer I'll kill everybody at plain site. :)

Christian Hupfer

@PauloCereda: You should wear nerd's glasses and correct the lecturer at any occasion

2:22 PM

@ChristianHupfer I already use glasses. :P

2:42 PM

Furthermore, MATLAB is a modern programming language and problem solving environment: it has sophisticated data structures, contains built-in editing and debugging tools, and supports object-oriented programming. These factors make MATLAB an excellent language for teaching and a powerful tool for research and practical problem solving.

The author is Nick Higham and I don't believe he meant this.

Anybody but him

@percusse what a BS?!

@tohecz Unfortunately the authors are excellent numerical analysts. I think they had to write appraisals in the preface. It's really sad

@tohecz I got it from this question tex.stackexchange.com/questions/197300/…

@percusse: You are clearly a mathematician or something pretty close since your sentences are always inverted in an (ε, δ) way. LOL

I wub you sir <3

@PauloCereda :)

2:58 PM

@tohecz That's good. It's a giant pain when these things drag out.

@JosephWright The evolve extension. That's a no, then? :-)

3:13 PM

@percusse who was my year all through University;-)

@percusse I disagree that MATLAB is excellent anything.

Q: Basic setup for LaTeX for Mac?

I have a professor who requires me to use Latex but he mainly speaks in terms of PC. I have a Mac so I have to find appropriate alternatives. So far I have purchased "Latexian" as an editor, and see that the MikTeX distribution is mainly for PC. It seems that the alternative for Mac is Mactex. ...

mactex distributions

Do we have a basic question for Mac uses concluding 'Use MacTeX'?

Q: Evaluating algebra expression using an auxiliary VB class compiled on the fly and consumed in a C# project

I want to create algebra evaluator but I don't want to write my own parser because it takes much time to learn. I don't like algebra expression in C# because it does not look natural compared to VB counterpart. For example, "x^2+1" in VB must be written as "Math.Pow(x,2)+1" in C#. I am still a n...

c# parsing reflection math-expression-eval

@ChristianHupfer Italian? Beware!

@cyanide-basedfood why not just write the main code in vb as well?

cyanide-based food

@DavidCarlisle Because I have not enough knowledge in VB and VB is not as popular as C# I think.

booo -80 16 hours ago reversal Serial upvoting reversed

@cyanide-basedfood I suspect it's the other way round given the age of vb (if you count the non .net version) But it must be easier/more efficient to write the code in vb than to write it in c# except for a bit reflecting into a vb class to evaluate a string, I would guess

cyanide-based food

@DavidCarlisle It maybe correct for some cases, I think :-)

@DavidCarlisle: How do you know about reflection? I don't think it is available in TeX. :-)

7:47 PM

@cyanide-basedfood Hello! :) I'll take a look. :)

cyanide-based food

@PauloCereda Thanks in advance. :-)

8:02 PM

@DavidCarlisle Ooh

8:16 PM

@cyanide-basedfood oddly enough, I have a day job

cyanide-based food

@DavidCarlisle So you are using either Java or C#?

@cyanide-basedfood mostly XSLT but C# on occasion or F# (which would be more fun for your examples, probably) blog.nag.com/2010/03/using-nag-library-for-net-from-f.html

cyanide-based food

@DavidCarlisle I see. Thanks.

@JosephWright @egreg will do anything to win a !!/battle

8:33 PM

@DavidCarlisle My serial voting made the trick. :P

8:44 PM

@DavidCarlisle How nice, I like F#.

8:55 PM

@DavidCarlisle I used both the \begingroup\lccode?=:\lowercase{\endgroup and \begingroup\edef\x{\endgroup tricks in a single answer. ;-)

9:12 PM

@egreg i noticed:-) unfortunately the l3 syntax stopped you squeezing in a % at end of line comment

@DavidCarlisle I could add some, just for completeness.

2 hours later…

11:13 PM

@cyanide-basedfood Do you mind if I suggest an alternative approach? It's been quite a long time since I worked with CLI, let me see if I still can remember stuff. :) Although CLI behaves quite differently than PermGen-based VMs (a space for class definitions and associated metadata) and you won't run out of class space, I'd rather stick to an static class instead of invoking a new class on each time just with some parametric changes. >>>

@cyanide-basedfood: >>> I asked a friend of mine and she suggested an interesting parser named Mathos, available here: mathosparser.codeplex.com . Since the paser is self-contained into only one class without external dependencies, you could simply incorporate MathParser in your codebase and voilà, you'd have a very easy to use class without the burden of generating classes on the fly. :)

11:33 PM

:17276750, @cyanide-basedfood hmph they broke our website, that blog was supposed to point to nag.co.uk/numeric/DT/fsharp/index.asp

@DavidCarlisle: Results matter. Trust NAG. I'm scared. :)

@PauloCereda it's supposed to make you feel safe and protected, not scared as far as i understand marketing slogans at all)

11:47 PM

@DavidCarlisle :P
