That awkward moment when you're doing a group presentation that's largely been an outside contribution (leaders are giving the presentation, slides made largely by (lovely) minions) and the only thing you can think of is "have they ever done this before?"…

Very good at what they do, but what they do is definitely not writing slides for presentations.

Love 'em to death.

Hi everyone.. I have a small question that is probably easily solved

How can I most easily scale equation to \linewidth? Using resizebox works but I have to insert dollar signs all over. Using the \varwidth environment worked at first, but won't go much lower than .8\linewidth

@StephanLehmke Probably I miss some things in Subversion! What I like about DCVS (Gir/Mercurial: haven't used Bazaar) is the local repo and the fact that making branches is straight-forward: I find it much easier to have different 'streams' ongoing with Git/Mercurial than I do with Subversion. Like I say, possibly this is a reflection of my lack of ability with the latter!

@1010011010 you should only need two $ (one at each end) but don't do it: scaling images is OK scaling text is evil:-)

@DavidCarlisle I am scaling a \ [ ... \ ] environment... It's errors all over.

@JosephWright Maintaining several branches of the same thing which are all developed in parallel is probably the main reason for the existence of git/mercurial/bazaar, so it's conceivable they are better at it than svn :-) But we don't do that a lot in my team, so it's not much of an issue.

@StephanLehmke For me, mainly useful if you want to add something 'quickly' but leave yourself easily able to still do 'release' updates while testing/developing

@StephanLehmke True for me too, mainly: would be handy sometimes, though

@DavidCarlisle Look me in the eye and tell me that rescaling the equation here is evil: i.imgur.com/DniOyOi.png?1

@JosephWright I don't exclude the possibility that I'd just love git once I'd understand how it works. It's like the emacs/vi debate: You're fond of what you're familiar with.

@1010011010 I'd work as well to put the last equal sign aligned into the next line.

@StephanLehmke Actually I'm probably happier with Mercurial, but can see the way the 'wind is blowing': when BitBucket changed their default from Mercurial to Git I decided the message was clear.

@StephanLehmke You don't think the equation would fit nicely on one line? I'd normally be okay with line breaking, but the representation of this equation makes me crave for resizing it rather than line breaking.

@StephanLehmke Haven't used Bazaar so can't comment

@HeikoOberdiek Thanks, that would be great. I can't speak any German at all, so it would be useful to have some tests to work on. :-)

@PauloCereda Thanks :-) The doctor says it's overuse! I had a frozen shoulder last year, but it's not been quite the same since and is deteriorating, so I need to cut down on my workload. I'll keep maintaining the packages I use for work (glossaries, datatool, flowfram and jmlr) and the ones I use to help manage those packages (makedtx and nlctdoc) as well as the ones my husband uses to create exam papers (probsoln and venndiagram).

As for the other packages, csvtools and glossary are obsolete, doipubmed is deprecated in favour of doi, and quotmark is deprecated in favour of csquotes.

@1010011010 I'm not exactly fond of two equals signs in one line so I'd probably have used an alignment even if it hadn't been too long on one line (unless there's a page restriction). But YMMV; typographic traditions vary a lot.

@StephanLehmke I've decided to do it your way. :-)

@1010011010 :-)

I'll just keep it this way. Thanks.

@JosephWright Spam:

@1010011010 I definitively would not scale that! I'd split it over two lines and if you really wanted to make it fit on one line I'd adjust the spacing (the space in the 2nd row matrix could easily be cramped) or failing that I'd use a class design size such as \small. I'd never arbitrarily scale mathematics/

@1010011010 well you are doing something wrong (apart from the fact that scaling math is wrong in principle:-) hard to say what though: \[ is a display environment so has to be used in vertical mode you can't put it directly in resizebox any more than you can put it in \mbox you would need a \parbox first but it would be better to use single $ as you want to allow it to be arbitrary width so you can scale it back. so just \resizebox{\textwidth}{$\displaystyle help dont scale me$}

@PauloCereda I'm getting the hand of this Lua business: by the end of the weekend I'd hope to have a first-draft set of build scripts for expl3 :-)

Hello :)

Hello @ALJIMohamed :)

@ALJIMohamed Hello

guys I have a small question ....

can I ask it here ? I don't think it will fit in tex.SE

I just need general ideas

can I ask it here ? I don't think it will fit in tex.SE

@ALJIMohamed well you just asked a question already:-)

@ALJIMohamed Chat is intended for off-topic stuff.

no ,not that one

hhh

no ,not that one

@HenriMenke cricket isn't off topic is it?

@ALJIMohamed just ask_:-) (is there a problem with your connection, some of your comments are being duplicated)

@NicolaTalbot I have written him an email.

@HeikoOberdiek Thanks :-)

@NicolaTalbot I found an online resource: calculino.com/de/umrechnungen/zahlen-in-worten_rechner.html. It uses a JavaScript for the calculations: calculino.com/sprache/rubrik/scripte/zahlen-in-worten/…

@HeikoOberdiek That's great. (I had to use Google translate on the instructions :-) but I've worked it out now.)

@PauloCereda you should come to this (I might go and you can explain Portuguese to me:-) lists.w3.org/Archives/Public/www-math/2014May/0000.html

@ALJIMohamed did you ask it? (I hope we didn't put you off)

sorry, I have troubles with my connection

well my problem is that ... there is Scientific day ... and I want to write an abstract for it

they provided a template but it is in MS Word !

I don't like it, I love LaTeX

I would like to make a LaTeX file out of the Template.doc

@ALJIMohamed Doesn't work like that

can you help me with that ? please

@ALJIMohamed If you can describe the layout required we may be able to help

the template.doc is available here fsk-uit.ma/jsim2014/Template_Short%20paper.doc

I don't know from where to start to make an equivalent of it in LaTeX

@ALJIMohamed You did see the line It is highly advised to use this template to prepare your paper in Microsoft Word., I assume?

I didn't pay attention to that

do you advise me to write it in Word ? :(

@ALJIMohamed Perhaps you could use tex4ht to help you convert LaTeX to Word.

@ALJIMohamed For a start, we don't know how 'hard line' they are on the format, so it's difficult to be sure

@ALJIMohamed However, normally for published work you have to go with what the publisher wants

hmmm

I see what you mean

I better write a paper using Word :(

that was my first question :)

@JosephWright are you familiar with research ... conferences ... seminars ... scientific day ... ?

@ALJIMohamed It depends: in my subject area, organisers ask for abstracts in templates but half the people ignore this so stuff is all over the place. However, I wouldn't necessary assume this is always true

@ALJIMohamed I'm an academic researcher

@JosephWright

@JosephWright cool

I have another question for you @JosephWright

There is a 1ST NATIONAL DAY ON COMPUTER SCIENCE AND MATHEMATICS

and my supervisor asked me to write an abstract for this day

but I don't know ? an abstract of what ? a résumé of what ?

@ALJIMohamed I guess he wants a summary of your previous work, which is related to the conference topic.

@HEnI am PhD

@HenriMenke I am phd student in my first year, I haven't published any paper yet !

@ALJIMohamed Well so it seems you should publish your first paper now. As the libraries are usually full of published papers, it sould be not too hard to find out what content to put where :-)

@ALJIMohamed Me neither, but when I am asked for any abstract I just summarize the work of the last few months and send that. E.g. for the last molecular dynamics conference I attended I summarized my work on a charge-to-lattice interpolation scheme I'm developing.

so the abstract, they are asking for, is a summarize of what I am doing right now and past few months.

interesting ...

@ALJIMohamed Obviously it would be best to pick something which can easily be presented as a self contained research report.

@StephanLehmke like what ?

@ALJIMohamed Well I don't know what you're working on ;-)

But I assume writing research reports has cropped up in other disguises as part of your studies so far.

Furthermore, supervisors are there precisely for giving advice on these matters ;-)

@StephanLehmke Yes I know how to write it

that's true

but I want to avoid to ask my supervisor

I asked him the first time, he wasn't clear

he said "summarize what you are doing and send it to me "

@ALJIMohamed ... so you're asking some complete strangers on the net ;-)

:D

you have already helped me

maybe you didn't notice that

@HenriMenke said "I guess he wants a summary of your previous work, which is related to the conference topic." :)

so I remember now what my supervisor want me to do :)

and I am asking complete stranger so that they explain to me more , that's all :)

I am getting a different and additional point of view ;)

bye

Spam: tex.stackexchange.com/a/176255/5049

@egreg there's no need for you (or for me, actually) to guess, but that doesn't mean the OP shouldn't be asked to edit the question so guessing's not needed:-)

@David: wow, that conference really interests me, as I can try to submit a paper. :) Will you be there?

I'm on mobile, gentlemen, so typing is slooooow.

Which document class they use here: math.umn.edu/~garrett/m/algebra/notes/27.pdf. Or, how they get text on all pages?

@PauloCereda don't know yet: I was somehow involved in the initial MKM meetings and the parallel OpenMath meeting er I'm editor of the spec and on the steering committee so I probably ought to go, and MathUI's run by Paul who's on the W3C Math WG, but I haven't gone every year (including one year when it was in Birmingham which is an hour up the road:-)

I don't mean how to produce text, just, how to make that text wide... Oh, my great english..

@Cortizol you can have the text as wide as you want (within reason) \setlength\textwidth{30cm} in the preamble will make it quite wide. The geometry package gives a perhaps better interface to setting the widths and margins and physical page size in a coordinated manner

@DavidCarlisle All right. I will see that. Thank you David

@DavidCarlisle Yes, I don't need them as today I'm rep capped at 230. You're still at 140, I believe, including my upvote for the UTF-8/CP1250 investigation.

Curiously, this kind of error produces Ĺ instead of Ã, which might account for you being slow in understanding the issue. :P

@egreg I didn't look at the pdf I did

$ file titlepage.tex
titlepage.tex: assembler source, UTF-8 Unicode text

@egreg file obviously didn't think much of his tex markup:-)

@egreg and I've gone a whole day without breaking latex

@DavidCarlisle It could easily go in my gallery of horrors.

I would be delighted if some knowledgeable people could check (and perhaps correct or improve) my (community wiki) answer in this topic. This question/answer aims to be a guide, so it's better if it's complete and completely correct...

@ppr You should have an example for BibTeX and one for biblatex/Biber.

@ppr hmm I think it's a bit confusing that you've used bibtex in the title but biblatex (which defaults to biber rather than bibtex) in the example. It's clear enough in your text if you know what they are but people needing help with an example don't always know that.

@ppr see @egreg said the same (but for once, his version was shorter:-)

@ppr also for some questions you can omit the filecontents and use one of the bib files in the standard path eg xampl.bib

@DavidCarlisle @egreg thanks for your remarks. I will update the topic with a distinction between biber/bibtex when I have a little time. Just to be clear: am I right to call a .bib file a bibtex one? It introduces a possible misunderstanding but, in my opinion, a bibtex file is a type of file (ending by the bib extension) which could be treated by biber or bibtex in order to produce a bibliography generated by biblatex or bibtex or natbib or ... am I right ?

@ppr “Bibliographic database”?

How to provide \neg, but rotated (like in Logic)? I found \rceil, but it was a little too big in my opinio. To use \rotatebox, or there is already command for that?

@Cortizol The same orientation as \rceil?

@egreg Yes.

\documentclass{article}
\usepackage{amsmath,graphicx}
\DeclareRobustCommand{\rneg}{%
  \mathrel{%
    \text{\rotatebox[origin=c]{-90}{\reflectbox{$\neg$}}}%
  }%
}
\begin{document}
$a\rneg b$
\end{document}

@Cortizol ^^^ I don't know what atom type you need, I set \mathrel.

@egreg It's symbol for negation in Logic. I know for \neg, but that is somehow weird for me.

@Cortizol That's the spacing for a relation; what should it mean?

@egreg I wrote above. I didn't see that I edit

@Cortizol Negation in logic is used as an ordinary symbol, so remove the \mathrel

But maybe a thin space should be added. Let me experiment.

\documentclass{article}
\usepackage{amsmath,graphicx}
\DeclareRobustCommand{\rneg}{%
  {%
   \nonscript\mspace{1mu}
   \text{\rotatebox[origin=c]{-90}{\reflectbox{$\neg$}}}
   \nonscript\mspace{1mu}\mspace{1mu}
  }%
}
\begin{document}
$a\rneg b_{a\rneg b}$
\end{document}

@egreg I will stick to \neg. This is good, but not enough for my needs. Thank you for helping me Enrico.

@Cortizol I'm not sure what typographical tradition your symbol is coming from. In the literature one sees ¬ and ~ for logical negation (which is a unary operator, btw).

Quack.

Salutations

@Canageek hello

Everybody out while I was having dinner. ;-)

UPDATE: today I defended my PhD!!! Done! I want to thank all the wonderful fellows in TeX.SE!!!! Thanks!

@Dror WOW! Congratulations!

Now, starts a new phase, at least as challenging... Job hunting :)

@Dror Procrastination doesn't help in this case, I'm afraid.

Could I take the weekend off?

@Dror no:-)

But I already promised my son I'll be with him. Without working

@Dror oh Ok then

@DavidCarlisle: Thnx

@egreg: BTW, what could help is help from friends ;) If you know of someone how need a mathematician, send him to me

@Dror I already have one. ;-)

@egreg: so...? Go ahead... make my weekend. It's your lucky day!

@Dror Congratulations!

So, I've decided to see how fast my i7-2600K can compile LaTeX, I'm expecting damn fast :D

@Canageek tikz will slow anyone down

@DavidCarlisle Hum, I'm tempted to try a sample file and compare it with my laptop.

@Canageek I assume you mean compile a LaTeX document?

@DavidCarlisle Sorry, but i had to star this one. :-)

@GonzaloMedina Didn't look into it, but it compiles fine with my TL2013

@Johannes_B Thanks!

@GonzaloMedina Overfull hbox tough

Evening all. Quick question re tex.stackexchange.com/questions/176369/…. I'm reading this as a "please fix my code" and am having trouble communicating to the OP that they should ask a question. Any advice?

@Johannes_B Yes, those I've fixed already and will update the code shortly.

*other than "give up, go home, and mow the lawn", which is what I should do...

Slow day today; just 195 rep. Well, I guess not all days one can get 300+ rep.

Correction: 210 now.

@GonzaloMedina de.wiktionary.org/wiki/…

@Johannes_B not one that translates very well. Maybe "scratching a living"?

@AndyClifton Don't know the right translation/approximation.

Best I can do. It's idiom rather than a direct translation.

The squirrel ist busy like a bee doesnt seem to fit, biologically.

@AndyClifton ah well I answered it now anyway:-)

@Johannes_B the alternative would be "my heart bleeds for you"..

@Johannes_B I hope you're impressed with my tikz foo in my most recent answer?

@GonzaloMedina Anxious about going 200K? ;-)

@DavidCarlisle I'm speechless. That's brilliant. Not sure if it's genius or troll-baiting, though

@AndyClifton the former, surely:-)

@DavidCarlisle Somehow I doubt you'll have that accepted as the answer, but I so wish it would be

@idiots I can read the chat too. Andy Clifton you need to realized the code works fine and nothing needs to be fixed. It is an exercise in learning. I bet none of you act in such a manner in person to people you don't know. If so, I recommend you start by finding me and testing it out.

@Johannes_B Unfortunately, Google translate just gives me some clues as to the meaning (I cannot read German), something like "laboriously the squirrel", but I guess I get the meaning :)

@egreg Apparently yes :)

@dustin Dustin, read the chat. I was asking the others on chat for advice. Not once did I call you out or say anything against you. Also, read the comments and look at the answer you've got: it's pretty plain that we're not seeing a question that we can answer. If you'd like, I can send you my phone number and we can talk about this.

@dustin the whole world can read chat:-) Actually I don't think it's a bad question, just a bit under specified as to what you want. My answer is more concise (and honestly I don't know any tikz so not much else I could suggest)

@DavidCarlisle I'm also in a similar position to David Carlisle. I don't do Tikz precisely because it strikes me as too "wordy", and so I tend to use things like omnigraffle. Dustin, If your question had specifically asked for help on one item in the drawing (and included the drawing) I would have probably up voted it.

@dustin I'm not sure there is a user with that nickname. I don't want to think that you used the word for addressing people here. Did you?

@egreg actually, maybe I should appropriate that name. Seems a good opportunity if noone else is using it..

Then you all need to check your attitude problem towards trying to learn and expand my experience, because it isn't appreciated. Additionally, I don't take it that. Andy I sear you said go home and mow the lawn. You just didn't say it to me but in a chat.

no, I was saying I should go home and mow the lawn rather than trying to help people who won't take constructive feedback..

@egreg the correct individuals know who it was for.

@dustin actually I don't understand your attitude? my answer was a mild poke at an underspecified question, it wasn't intended to do much other than amuse a few people (perhaps even the OP) and perhaps (although a secondary aim) make you consider tightening up the question a bit so that my answer wasn't an answer.

@dustin Well, so I'll flag it.

@dustin I gave you an opportunity for apologizing.

Okay, let's all change the subject please. No need to argue in chat :)

@WendiKidd lesson learned - giving constructive feedback isn't easy.

@AndyClifton No worries, no one's in trouble. Just making an attempt to calm things down :)

@JosephWright Yep. Old laptop vs the top of the line chip as of 2 years ago.

@JosephWright I'm thinking of overclocking it, as I already have massive cooling in there

@DavidCarlisle @JosephWright The readme "mess" is not fixed yet. Karl misses 00readme.txt in cyrillic. As far as I have seen: base contains 00readme.txt with README as link, graphics only 00readme.txt, cyrillic: README, tools: readme.txt. Can the naming scheme be unified?

@HeikoOberdiek let me check...
