@percusse thanks! Based on your suggestion, I tried some more things, and it turns out that XeTeX didn't use the Windows fonts, but the fonts from the dejavu package in my texmf tree, so basically the same problem as tex.stackexchange.com/questions/84223/…. My assumption would be that you don't have the dejavu package installed, is that correct?

percusse

@doncherry Indeed. That's the case

@PauloCereda Here is something for you

Nevermind the description environment it's just a quick tryout. Suit yourself :)

Other platonic solids are also there if you like to try heheh.

@egreg I deleted a book from a Russain section because I do not want to add redundant information. The deleted book is accessable from the last item (the university starter page). Do you still want that book? Then I need to correct its link.

Stephan Lehmke

How much work do you put in a review? Usually, when I get things to review I click on "skip" as I don't feel I can say whether the change will be an enhancement or not. Lately, I've been giving edits the benefit of the doubt a little more. For instace, just now I approved an edit where one russian book about LaTeX was exchanged for another one, trusting the author of the edit would know best. It seems that was not such a good idea, as @egreg reworked the edit right away ;-)

But I wouldn't have had a chance to really judge whether the edit was justified contentwise. Should I have clicked "skip"?

egreg

@MaNarPi I can't read Russian; but I found that simply changing one book with another was not a fair thing to do. If you think that the book you removed should be removed, please add some reason why.

MaNarPi

@egreg Sorry. I added the deleted book too. I recognized that the deleted book is accessable from the last link. This is the link of the book: tex.uniyar.ac.ru/doc/kotelnikovchebotaev2004b.pdf and this the last link: tex.uniyar.ac.ru As you can see the domain is the same.

Stephan Lehmke

@egreg Well it was the same author putting it in and exchanging it for another one. So it could be unfair to himself at most...

egreg

09:05

@StephanLehmke I'm a bit lost

Paulo Cereda

@percusse ooh thank you! <3

tohecz

!!/echo Hello!

Paulo Cereda

@tohecz Morning! :)

kan

Hello friends! Can I ask for some vi help?

tohecz

@kan yes

kan

09:08

How does one detect tab key characters?

Sage does not build because of one tab character sigh.

tohecz

In search? by
\t

I mean:
/\t

Paulo Cereda

If you want to show control characters, go with

:set list

kan

@tohecz Works cool! Thank you.

Paulo Cereda

To disable it,

:set nolist

kan

@PauloCereda Ooh. Nice... :) Thank you! :)

Is there a way to replace every tab by corresponding number of spaces?

tohecz

09:13

@kan yes

it is
:%s/\t/    /g

kan

(I put in way too many of them. :( )

tohecz

as well, see
:help 'et'

Paulo Cereda

:set tabstop=2 shiftwidth=2 expandtab

Then

:retab

tohecz

and possibly
:set sts=30

Paulo Cereda

@tohecz ooh! :)

@tohecz: I wonder what David will say when he sees our heavy Vim talk. :P

tohecz

09:16

Btw, @kan, you're really lucky to meet two vimmers here ;)

kan

@tohecz yes, more so, since David is not around. :)

Paulo Cereda

@tohecz So true. :)

David Carlisle

@PauloCereda I just turn up in time to see my name being taken in vain again :(

@kan no

Paulo Cereda

@DavidCarlisle <3

kan

@DavidCarlisle Sorry. :)

kan

09:49

TAB characters are Evil.

David Carlisle

@kan M-x untabify. Oh sorry, you use vim.

kan

Is it considered bad in the developer circles if I replace every tab, even the ones that don't cause trouble with appropriate number of spaces...

@DavidCarlisle See, you make me feel bad now. :(

tohecz

@DavidCarlisle :retab

@kan no, it's ok if you use such thing as a 2-D programming language

kan

@tohecz OK. More specifically, this is a patch for sage; well not a big one though.

Sage is developed in Python , well, you know.

tohecz

@kan I do know. I don't use sage, but that doesn't mean I don't know it

kan

09:59

@tohecz That's what I said no, "you know" :P

I am going to clone a new branch!

God forbid any more danger.

David Carlisle

@kan In my own code I zap tabs (did I mention I use emacs?) but if it is a shared code repository cosmetic changes are a bit of a pain as it inflates the size of the diff and makes code review harder. Also white space changes in python (if that's what it is) are scary as it's rather sensitive to space as I recall so any such change would need a review

kan

@DavidCarlisle Yes. All changes to Sage are reviewed. But, I was worried if it will be frowned upon if I make trivial changes.

(like tab by space, oh, but are you explaining it is a non-trivial change?)

Uh-oh! I forgot to keep the right patches! GOD!!!!!!!

David Carlisle

11:09

@kan If you are new and want to make the reviewer happy and quickly pass your code I'd keep the patch as small as possible and focused on the functional differences. If it is the reviewers code that you are changing and you check in a patch saying the code was ugly and you're fixing it, it may not endear you to the reviewer:-)

Paulo Cereda

OMG I found a paper with 15 authors!

kan

@DavidCarlisle Yes. I worked out as much. What I am now doing is cloning a new branch from the main and just making the right changes so that Without using tab characters.

Paulo Cereda

I won't use Foo at al, but Foo et omnes.

David Carlisle

@PauloCereda when I started to work on revtex4 (I gave up before it was finished) the spec was that the automatic layout had to cope with 4 or 5 hundred authors...

Paulo Cereda

@DavidCarlisle OMG

David Carlisle

11:18

@PauloCereda Cultural differences, mathematicians list the people who worked on the paper as authors, in alphabetical order. Physicists list everyone remotely associated with the research project and the lab, in order of seniority.

Andrew Stacey

@DavidCarlisle Never forgetting to add F.D. Willard to the list.

Stephan Lehmke

@DavidCarlisle In fact, for instance at the LHC in Geneva the size of research teams who do contribute to a result is really in the hundreds. This in some sense relativizes the basic idea of "author". A nephew of mine works at/for that lab.

Jörg

@DavidCarlisle I found an incompatibility with your answer of my "grid search" question.

David Carlisle

@Jörg ?

Jörg

@DavidCarlisle Sorry, I meant an incompatibility with another macro that I use to force a line-break in a column (a made a comment to your answer)

David Carlisle

11:29

@StephanLehmke yes it depends a bit whether you think "author of paper" should mean that you contributed some words to the document or that you were involved in the research.

@Jörg I'll look you can probably just locally redefine the command as I did for midline in the savedata bit

kan

Another help friends. Sorry, for all these newbie questions.

Jörg

@DavidCarlisle I'll try that

Stephan Lehmke

@DavidCarlisle I think that also in math it's rather seldom that one person writes a paper about the research of another person (if it's not about history) without having that person as co-author.

kan

Suppose I'd like a file to be accessible by both root and foo_bar, in whose group should the file be in?

David Carlisle

@Jörg I put a comment on site

@kan root can see the file anyway can't it?

kan

11:35

@DavidCarlisle root can, but root seems to be unable to write into a particular file, which was strange to me as root must be able to do anything to all files, apparently.

David Carlisle

@StephanLehmke research is always based on someone else's work, that's the nature of the beast, but also what the references section is for:-)

Stephan Lehmke

@DavidCarlisle That's not what I meant, because it would imply the other person has published "their research" independently. But this is really about hundreds of people working together on one result, no chance to split it up so everyone can publish "their" part.

David Carlisle

@StephanLehmke yes I realise that spending a few million euros on some tunnels under cern results in a different kind of process than buying a couple of notepads and a pencil for maths research. The convention is what it is so it can't really be changed although it still looks odd to me to have authors listed in a paper who probably didn't even know that paper was written at all.

Jörg

@DavidCarlisle Got it to work, thanks :-). Better hurry for teaching now...

kan

11:55

sob Doctests are being unfair to me.

Gigili

Hello.

@kan Did you see my question there on MSE?

Joseph Wright

@Gigili Hello

Paulo Cereda

@Gigili 'ello!

kan

@Gigili I don't have an account on MSE. Thank you and sorry.

Gigili

Is it possible to copy-paste pictures to a TeX document as I used to do in MS word?

Joseph Wright

12:03

@Gigili No

Gigili

What should I do then?

Joseph Wright

@Gigili TeX files are plain text, so you include instructions it place the graphic content in the appropriate place

Assuming LaTeX, \includegraphics

Gigili

Right. Thank you.

Joseph Wright

You need the graphic in the right format: with an up-to-date pdfLaTeX set up, .pdf, .png, .jpg or .eps

David Carlisle

comic sans? tex.stackexchange.com/questions/84768/…

Stephan Lehmke

12:06

@JosephWright Preferably PDF and PNG, I believe.

Paulo Cereda

@DavidCarlisle Yes, with fncychap. :)

Joseph Wright

@StephanLehmke If you have a vector original then PDF is preferred (although EPS => PDF conversion retains this, of course). For bitmaps, I guess if the original is in PNG format then this is better as its not lossy.

Stephan Lehmke

@JosephWright PDF is also great for bitmaps.

Andrew Stacey

Just wanted to make sure that all TikZers had seen this:

11

Q: Summary of Tikz commands

Many times, when I'm coding a tikz-picture, I don't remember the command syntax or the name of one option, and I have to look in pgf-manual is not very short. Does anybody has a summary of Tikz commands fit to one or two pages?

tikz-pgf

I made a start on a CW answer, hopefully others will contribute.

(But don't show it to @DavidCarlisle otherwise he might start answering TikZ questions)

David Carlisle

12:50

@AndrewStacey you mean as well as my other speciality of luatex font handling?

Stephan Lehmke

13:33

Can I downvote a question because it's insulting to TeX?

0

Q: Smarter latex justification to avoid large spaces

The default format in latex for paragraphs is fully justified, where the first word of a line touches the left margin and the last word of a line is flush with the right margin. This is nice for lines that are about as long as the width of the text area, but if there are few words, LaTeX will ...

horizontal-alignment

Paulo Cereda

@StephanLehmke We could comment that TeX is smarter than the average bear. :)

kan

Submitted a patch, keeping my fingers crossed.

Stephan Lehmke

@PauloCereda :-)

Andrew Stacey

@StephanLehmke Ooooh ... I'd be tempted to join you in that. But I shan't! Instead, I encourage you to edit the question to one that is more acceptable.

Stephan Lehmke

@AndrewStacey I wasn't the one who downvoted! That the OP does not know what a TeX document should (and can) look like is not their fault. It's just so painful to think that there are people out there who think this is what TeX output is supposed to look like :-(

Andrew Stacey

13:54

@StephanLehmke I know you didn't - when I looked it had no (net) downvotes. And I agree that this is a sorry state of affairs if this is what folks think TeX produces. You can lead an author to TeX, but you can't make his articles look nice.

percusse

I don't think we should ban ranting about TeX in here. I saw recently another question that was ranting about TeX and similar remarks have been posted. This IS the place to rant about it instead of Word users forum or somewhere else since our wizards can tell what is what better than non-TeX users posting nonsense about TeX like the question mentioned above.

No matter how preposterous it might be ...

Andrew Stacey

@percusse ranting is fine, but misinformed ranting not. What irritates me a bit is people posting a question with the assumption that the fault is in TeX (or TikZ, or some package) instead of in what they've done. I've lost count of the questions with "Possible bug in TikZ" which turned out to be "I've done something stupid but don't know what".

(To be absolutely clear: "I've done something stupid - or may have done - but don't know what" is absolutely an okay question to ask.)

Paulo Cereda

@AndrewStacey People deliberately naming things "bugs" in the wild scare the living daylights out of me.

percusse

@AndrewStacey Absolutely. However, we don't have the power of educating people a priori. It's the climax of twitter and everybody thinks that they are entitled to express any nonsense online and they can not be wrong on any aspect. So it might be the case that we have high expectations from online world.

After two bug questions people usually go back to normal human mode and we have seen that happening here with some exceptions of course :)

Paulo Cereda

@percusse must... resisit... tweeting... about... it...

percusse

14:02

@PauloCereda For a long time I couldn't even find the damn twitter.com page. I thought it was tweeter.com

Paulo Cereda

@percusse :)

Andrew Stacey

@percusse But we do have the power of editing their posts. I've yet to do so, but I'm often tempted to tone down the titles of such questions a bit.

Paulo Cereda

@percusse:

Beware of the bug. Beware of the bug. BEWARE OF THE BUG!

@AndrewStacey I can not agree more. I should try better :)

@PauloCereda I tweet, I tweeted, I've tweeted, twitter.com Doesn't compute...

Andrew Stacey

It's one of those irregular verbs, isn't it: "I write thoughtful and insightful comments in less that 143 characters, you mention odd things that have happened to you during the day, he she or it spews forth rubbish."

percusse

14:10

@AndrewStacey The thing at the top is the tweeter for me and always will be (though 14000$ a pair) :)

Andrew Stacey

@percusse "I see you've got your negative feedback coupled in with your push-pull-input-output. Take that across through your redded pickup to your tweeter, if you're modding more than eight, you're going to get wow on your top."

percusse

@AndrewStacey Amazingly this time I got the reference. Heheh. I'm just an eye-fetishist (I hope this doesn't mean that I poke people's eyes) I was subscribed to Stereophile for a long time until they wrote an article about speaker physics. Then I said okkey they don't know what they are talking about.

14:31

Hello friends, is the following code the optimal for what it produces:

\documentclass{article}
\begin{document}
{\setlength{\arraycolsep}{2 ex}
$$\begin{array}{r|*{6}{r}}
\multicolumn{1}{c|}{\ast}&a&b&c&d&e&f\\ \hline
{}a&a&b&c&d&e&f\\
{}b&b&a&d&c&f&e\\
{}c&c&e&a&f&b&d\\
{}d&d&f&b&e&a&c\\
{}e&e&c&f&a&d&b\\
{}f&f&d&e&b&c&a\\
\end{array}$$}
\end{document}

Meaning to say, if a program produced this code, would you be happy with it? And, do you think the program should produce an indented code?

Paulo Cereda

@kan At least, make it add some spaces. :)

Andrew Stacey

@kan _dollars_?!?!?! Definitely not.

percusse

@cmhughes Houston we have an indentation problem.

2

kan

@PauloCereda OK, what other things would you like? I will modify the code accordingly.

@AndrewStacey Oh, sorry about that. I put it in so that you'll copy paste and try it out. :)

percusse

@kan multicolumn with 1 column seems redundant no?

kan

14:40

The output will just begin with {\set... and upto \end{array} .

Paulo Cereda

@kan If the file is generated by a tool, I think it's wise for you to include a header (some comments at the top of the file) with a timestamp and some processing info.

kan

@PauloCereda Actually, I don't think timestamp is required. And, this is going to be accessed from within sage. like, if T is a table, calling latex(T) produces this object.

Paulo Cereda

@kan It's up to you, of course. :) But don't tell I didn't warn you. :)

kan

And, yes, I agree, there could be a header that says which table is that the code for. And, also, alert the user that $$ is to be inserted appropriately.

@PauloCereda Oh, I won't! Defects are mine! And, the niceties are that of the community. :)

Andrew Stacey

@kan In that case your crime is all the worse.

kan

14:49

@AndrewStacey Oh :( What did I miss?

Andrew Stacey

@kan You manually put in dollars ... instead of \[ ... \].

kan

@AndrewStacey Argh!! I was just mentioning this to @Paulo for the cube. :(

David Carlisle

@kan unusual although not necessarily wrong to use ex units for a horizontal measure, last \\ is sort of OK but shouldn't really be there, same of all the {} Unless you don't know the content at that point so there might be a [ It depends a bit what your real code does but beware of where you close that group started with {\setlength strange effects can happen by putting display code in a group.

kan

@percusse Hmmm... I am not sure... can you point me so that I could read up on the nitty gritties.

David Carlisle

.. and @egreg picks up yet more points for putting % at ends of lines.

egreg

14:59

@DavidCarlisle I just followed your example. :)

David Carlisle

@egreg in L3-ish code as well this time:-)

kan

@DavidCarlisle What unit of measure should be used instead? I'll fix the last ` \` ...

Actually, there is a primitive stuff written in Sage but has strange bugs and hence this.

David Carlisle

@kan ex is (nominally) the height of an x so is mostly used for setting vertical things to visually match the lowercase text run. em (nominally the width of an M) is usually used for horizontal stuff

kan

@DavidCarlisle OK. So, we need em because we are dealing with horizontal (column) spacing... Noted! :)

@DavidCarlisle The code will just spit the how to typeset some tables in LaTeX. So, the routine will just output code for constructing a particular table constructed in Sage.

percusse

@kan I mean just remove the multicolumn and leave only the \ast and compare the results.

kan

15:04

So, nothing fancy. Is there a possibility of anything behaving strangely?

@percusse Hah! OK! It does work! But, there is a problem, there may be other kinds of table that this code might have to handle. So, looks like this might not be possible to circumvent. But, fair point. I have noted it down...

percusse

@kan I see. I would jut use pgfplotstable but I'm biased :)

Jörg

15:19

@DavidCarlisle Sorry, I have more issues with the grid search table thingy...`savedata` does not like the following two things at the beginning of a table:

&\multicolumn{2}{c}{Savings}&\multicolumn{2}{c}{Savings > \pounds500}&\multicolumn{2}{c}{Savings > \pounds1500}\\ % here the problem is ">" and "\pounds"

or

&\multicolumn{1}{c}{> \pounds100}&\multicolumn{1}{c}{> \pounds500}&\multicolumn{1}{c}{> \pounds1500}\\ % here the issue is only ">"

I tried a few modification with \let\multicolumn\@gobbletwo but without success

David Carlisle

@Jörg will you ever want to use the multicol text? If not you want \let\multicolumn\@gobblethree except that isn't defined so \renewcommand\multicolumn[3]{}

or you could change \expandafter\xdef\csname data-#1(\the\rowc,\the\colc)\endcsname
{\zap@space## \@empty}\cr   to use \gdef instead of \xdef and just have {##} instead of zapspace then it will be safe for any content but the saved result will have white space before or after the number which you might need to account for when using it

Jörg

@DavidCarlisle Yes I think I need to access some values stored in multicolumns

Andrew Stacey

So we've had just-do-it-for-me, can I create just-read-the-manual-for-me?

Paulo Cereda

@AndrewStacey Let your spirit soar. :)

Andrew Stacey

15:40

@PauloCereda I know, I know.

@PauloCereda Incidentally, your ducks and tortoise rather grabbed the limelight when I was giving my talks (more so than the mathematics). Remind me of their names, please.

Paulo Cereda

@AndrewStacey Wallace and Wilbur, I guess?

Andrew Stacey

15:55

@PauloCereda loopspace.mathforge.org/discussion/14/…

Paulo Cereda

@AndrewStacey awww <3 There's no need for an acknowledgement. :)

Andrew Stacey

@DavidCarlisle @egreg Can I check my understanding with you? catcodes are frozen at input time (modulo nefarious schemes) but it would appear that mathcodes are not. So that if I do \def\a{b} then do $\a$ , the mathcode of the resulting b is the current mathcode, not the one when \a was defined. Is that right?

cmhughes

@percusse hi percusse! :) what's the problem?

Andrew Stacey

@PauloCereda Well, I don't want anyone to blame me for them.

egreg

@AndrewStacey Yes.

Paulo Cereda

15:59

@AndrewStacey <3

Andrew Stacey

@egreg So making, say, s mathactive just leads to headaches when writing, for example, \sin(x) because the s that eventually gets typeset is still active despite the definition of \sin occurring a long, long time ago. Hmm. The drawing board is calling me back.

egreg

@AndrewStacey Yes, that's a big problem. :)

cmhughes

@percusse I've got to go now :( feel free to ping me back with a snippet that doesn't work properly :)

Andrew Stacey

@egreg Hmm. Had high hopes for mathactives. Basically, I want a to expand to <mi>a</mi>. I guess as the eventual output will be text I could make a expand to \text{<mi>a</mi>}. My current method uses grouping and conditionals so that a first tests to see if it is already inside such a group and if so just produces a, if not it produces <mi>a</mi>.

David Carlisle

@AndrewStacey yes a character token is just two numbers a character code and a char code, so once it's tokenised that is fixed, but mathcodes upper and lower case codes etc are lookup tables from the character code to whatever

@AndrewStacey not sure what you mean by ` s mathactive ` if you make s catcode 13 then \sin is three tokens, but there is mathcode "8000 which is different but similar

Andrew Stacey

16:16

@DavidCarlisle I mean the mathcode "8000 thingy. I want \sin to be a command, but also s to be a command. As this is all in math-mode, I thought that the mathcode "8000 trick would make this work.

David Carlisle

@AndrewStacey well it does, but make \sin expand to \hbox{sin} then you won't trigger the s again

Andrew Stacey

@DavidCarlisle Right, so that's the sort of trick I need to employ: use mathcodes to expand my range of commands but then use \hbox to ensure that when I have something that I really need to typeset, it is back as ordinary text again.

David Carlisle

@AndrewStacey or write the tex to mathml convertor in a more sensible language like perl:-)

Andrew Stacey

@DavidCarlisle But then I'd either have to reimplement TeX in Perl to handle macro definitions (oh wait, I've already done that!) or use a subset of TeX and so effectively cripple what I most like about writing in TeX (oh wait, I've done that as well).

4

David Carlisle

@AndrewStacey LaTeXML implements essentially all the of TeX's macro expansion mechanism in perl (but not the typesetting so you lose, or at least have to add customisation, if things measure boxes) Or of course teh tex4ht route which is to let TeX do all the expansion and then extract stuff from a custom dvidriver when it's all done

egreg

16:29

@AndrewStacey You might use amsmath and append to \newmcodes@ code that restores the mathcode of the letters you need to their normal one. (The original code is in amsopn.sty)

David Carlisle

@AndrewStacey you might need this if you use latexml:-) svn.kwarc.info/repos/stex/trunk/sty/etc/tikz.sty.ltxml oh I just looked what Michael does there he cheats and hands over to tex4ht so latexml and tex4ht would be pretty similar in that case:)

Andrew Stacey

@DavidCarlisle See, that's where I win. I can use the genuine TikZ to create a nice graphic (possibly as SVG) and I can get the output to simply include it as an image (which is what, 90% of the time, I want).

David Carlisle

16:46

@AndrewStacey well I guess that's what tex4ht is doing also in that case.

Andrew Stacey

@DavidCarlisle True. The main advantages of my approach are: 1) Flexibility (output can be anything, not just XML) 2) I wrote it.

David Carlisle

@AndrewStacey yes I know about all those advantages:-) But if you make every character active (or even mathcode "8000) some things will break (I know you don't care so long as tikz works, but just saying....)

@AndrewStacey here's a test document for you to convert $s=\the\mathcode'\s$\bye (with a backtick in the middle not '

Andrew Stacey

@DavidCarlisle Taking you seriously for a moment, the third advantage of my approach is that I don't expect to produce sensible output for every input. My approach is that you need to know the type of output before you begin and write your document accordingly. But within those constraints you should have the full flexibility that TeX affords.

David Carlisle

17:06

@AndrewStacey maybe I just get too cynical in my old age but everyone believes that their translator works for a reasonable subset of tex input but it ends up just accepting their tex documents I have some convertors here that definitely only work on NAG documents::-) If I write a one line testcase as above it's clearly just silly input designed to break things, but it is not so untypical if you let a convertor out into the wild and people expect it to work with breqn or bm or ...

Andrew Stacey

@DavidCarlisle cynicise away! You are absolutely right. But my goal is not to write a general purpose converter that will work on absolutely any LaTeX document, nor to release anything in the wild. My goal is to make it possible for me to write any type of document (research article, blog post, e-book) using LaTeX.

(That's not to say that I won't release it into the wild, just that I won't pay any attention to bug reports.)

David Carlisle

"nor to release anything in the wild" That's where I went wrong, all my weekend tex hacks are out in the wild causing support messages 20 years later:-)

Andrew Stacey

17:29

@DavidCarlisle See, that's where you've been going wrong all these years.

percusse

@cmhughes I was referring to the message and Kan's auto output. Maybe one can put that in as an arara directive/rule such that it comes out both PDF and a fantastically indented code.

3 hours ago, by Paulo Cereda

@kan At least, make it add some spaces. :)

Andrew Stacey

18:00

@PauloCereda I know that it is by design that arara does nothing if it finds no rules, but I'd quite like to specify a default action in that case. Could this be possible? I'd be happy for it to be an "opt-in" (so I could specify it via the configuration file).

My reason being that I invoke my tex compilation program from within emacs, so buffers can have their own local program and there's a system-wide default. But often I get these mixed up and set the system-wide one (for a session) to arara. Then an ordinary TeX file without a local setting doesn't compile.

Paulo Cereda

18:12

@AndrewStacey I need to take a look at the code, but I think an entry in the default configuration file might be feasible. :)

percusse

18:23

@PauloCereda Ooh, key=value system in arara

@FaheemMitha But, for the life of me, I am still trying to see how to add an extension. sigh

Faheem Mitha

@kan OS?

kan

hg collapse was that SO answer.

Faheem Mitha

@kan That sounds like histedit.

kan

@FaheemMitha Ubuntu 12.04, using Hg 2.0.2

Faheem Mitha

19:30

@kan the mercurial channel on freenode is quite friendly

@kan Ok, that should be easy then.

kan

@FaheemMitha Oh, I see.

But, Sage should really do git.

Faheem Mitha

i don't think anywhere on SE does real time support for hg

though of course SO will answer questions. really irc is your best bet for questions like this

kan

I tried hard to learn git and learnt reasonably sophis. stuff.

Faheem Mitha

@kan You're a math student?

kan

@FaheemMitha Yes. :)

Faheem Mitha

19:34

@kan enabling extns should just be a matter of adding a suitable .hgrc.

Just copy the system one and uncomment

hmm, looks like these days they just ship a blank hgrc

i can offer mine, if it is of any help

i use debian

kan

@FaheemMitha Please do so. :)

All I have is my [ui] there...

Faheem Mitha

@kan paste.lisp.org/display/133973

But you can find examples all over the net, i'm sure

kan

@FaheemMitha Thank you, so much... I'll set it up now.

kan

19:56

@FaheemMitha Done! Thank you once again.

Paulo Cereda

Tried Mendeley, didn't like it. Better keep my own article management scheme.

Joseph Wright

@PauloCereda My conclusion too, when I tried it (some time ago now)

Paulo Cereda

@JosephWright I didn't even let it finish scanning my articles. :P

kan

@PauloCereda ooh, reminds me of my project.

Paulo Cereda

@kan How is it going, by the way? :)

kan

20:00

@PauloCereda Well, embarrassingly slow, I have just started to read up on the watchers... It will take another excruciating month or two. :)

Paulo Cereda

OFF: speaking of articles, I had an old paper of a friend in which I used ImageMagick's convert to convert all pages of the article (PNG files) to a proper PDF file. :)

@kan Don't give up. :)

kan

@PauloCereda I won't, surely. I want to build it, atleast for me.

Faheem Mitha

@kan Sure thing.

Paulo Cereda

20:20

A PDF document generated by TeX & Friends in a Retina Display = OMG.

Joseph Wright

@PauloCereda In what way?

Paulo Cereda

@JosephWright It's awesome. :)

Now I'm trying SugarSync too. :)

After all,

:P

Joseph Wright

@PauloCereda Do you get the odd ad woman?

:-)

Paulo Cereda

@JosephWright Yep. :) She throws the iPad! :P

Think of a very sexist ad. :P

Joseph Wright

@PauloCereda Exactly. I wonder what they were thinking!

Paulo Cereda

20:29

@JosephWright I like to call it guerrilla marketing. We have a lot of these in Brazilian television.

Joseph Wright

@PauloCereda I don't tend to watch much TV except the BBC, so no ads :-)

Paulo Cereda

For example, every beer ad here has at least one sexy woman in bikini. You barely see the beer in the ad. :)

@JosephWright Lucky you. :) Public TV here is terrible. :(

Faheem Mitha

20:48

@PauloCereda That's what the internet is for.

'ello!

Joseph Wright

@tohecz Evening

tohecz

@JosephWright everything fine?

Joseph Wright

@tohecz Here, yes. I'm ironing and listening to Mozart on the radio. You?

tohecz

@JosephWright I had a very busy day, two more such to come. However, things seem to be ok. I listen to Moravian "artifical folklore" (very impressive, I love it!) :)

Paulo Cereda

21:49

@JosephWright C'mon! How about some System of a Down? :)

Or something from UK, like, say, Pink Floyd. :)

Joseph Wright

@PauloCereda Before Performance on 3, I was listening to some English folk music: album Broadside by Bellowhead (possible folk album of the year)

Paulo Cereda

@JosephWright boo! :)

percusse

@PauloCereda Seems like an arara job no?

Q: How to automate mpost for FeynMP Graphics via Texmaker + Miktex on Windows 8

Producing FeynMF graphs requires manual running of mpost command on .mp file at terminal each time after [latex] compiling the tex document. In other words it goes like this: Latex + dvips + ps2pdf + View PDF mpost abc.mp Latex + dvips + ps2pdf + View PDF As you can see it takes three steps t...

A: Configuring Texmaker to run mpost for FeynMP Graphics

With an updated TeX Live 2012 there's no need to call mpost from the command line, since this program is allowed to be called during the LaTeX run. Just modify the definition of \endfmffile to do the Metapost run. \documentclass{article} \usepackage{feynmp} \usepackage{ifpdf} \ifpdf \DeclareG...

@egreg Looks like the same user

@JosephWright mod axe is going to blow...

egreg

@JosephWright With a very nice comment in the old question. :(

I thought I will get an answer quickly. — Laura Sep 27 at 13:18

Joseph Wright

22:11

@egreg Saw that

egreg

@JosephWright I don't know if mpost is in the list of allowed programs for the restricted shell escape also in MiKTeX. Can anybody confirm?

Joseph Wright

@egreg It doesn't seem to be

egreg

@JosephWright Darn!

tohecz

@Joseph I think this one can be migrated to either Academia or GD, it's got 4 votes already:

Q: Choosing a font for a thesis

I'm working on my thesis and I don't really know what font is the best choice for thesis work. I'm really convinced of only one thing: I don't want to use Times New Roman. First I checked on the latex fonts catalogue but there are too many fonts available. Which fonts do you think are the best fo...

@tohecz Done

tohecz

22:21

@JosephWright thx :)

btw, @egreg, do you drink coffee?

egreg

@tohecz Yes, of course. But real coffee Italian style.

tohecz

@egreg ok, so how large is your coffee?

egreg

@tohecz How small, you should ask. :)

tohecz

@egreg whatever

egreg

@tohecz Usually I have espresso coffee; you should know the size of cups. But we never fill them.

tohecz

22:25

@egreg so it's the one that after you drink it, more than half is still in the cup?

egreg

However, in the morning I have a big one with the home tool; the size that's usually for three people.

Moka pot

The moka pot, also known as a stove top espresso machine, is a coffee maker which produces coffee by passing hot water pressurized by steam through ground coffee. It was first patented by inventor Luigi De Ponti for Alfonso Bialetti in 1933. Bialetti Industrie continues to produce the same model under the name "Moka Express". The moka pot is most commonly used in Europe and in Latin America. It has become an iconic design, displayed in modern industrial art and design museums such as the Museum of Modern Art, the Cooper–Hewitt, National Design Museum, the Design Museum, and the London ...

tohecz

quickie: which package provides \resizebox?

egreg

@tohecz graphics (and graphicx)

percusse

@tohecz graphicx?

tohecz

@egreg thx

@percusse thx

percusse

22:27

@egreg bah, I'm not playing with you anymore.

David Carlisle

@egreg mcdonalds.it/tazzine-seletti-per-mccafe ?

percusse

:)

@egreg I'm having too much of it lately. Is there any known local side effects because I'm getting a little worried.

I also have it at home and using it extensively.

egreg

@percusse I can sleep very well also if I have a cup after dinner.

percusse

@egreg The key part is a cup. I'm having like 3

but going to bed quite late.

no correlation. I've tested it.

tohecz

@egreg is is possible that I know it as MoccaPress, or it's something different?

Paulo Cereda

22:36

@percusse Indeed. :)

egreg

@tohecz That's instant coffee!

Paulo Cereda

@egreg ooh! :)

tohecz

@egreg no, I don't mean an instant coffee, is it possible that someone calls Moka Pot this way?

egreg

@tohecz I don't know.

tohecz

And is it the one where you need the coffee to be very finely ground?

egreg

22:53

@tohecz Yes, but not too finely. Espresso coffee machines need finer coffee

tohecz

@egreg ok. Well, just to make sure: I like the French coffee size (cca 4 cl)

egreg

@tohecz In some rare places in Paris you can have a decent coffee. :)

tohecz

@egreg I'm happy with the fact that I pay 38c for my coffee at work, I really don't search anything more
