@Canageek the dice one?
Something very strange:

doesn't work, but

does work...
I can't understand how this can be possible.
12:18 AM
@DavidCarlisle Yeah. Lots on how to put them into the header, or how to draw them, but none on how to ensure a proper distribution.
@DavidCarlisle I could even put together a simple algorithm to do it, but I'd how no idea how to put it into LaTeX
@Kasper Minimal example? This works for me:
N := Number of pages
S := Number of sides on die
A := N/S (rounded down)
For(i=0 to S)
Randomly place A copies of i throughout document
@Canageek i half coded something yesterday but it was too late and I went to bed, i might finish it off if noone else does, but not tonight:-)
@DavidCarlisle I wrote a better psudocode, I think.
Pages := Number of pages
Sides := Number of sides on die
Count := N/S (rounded down)
Set all pages to false
for(i = 1 to Sides)
while(j := 0, j < Count, j++)
Random := Random number between 1 and Pages
if(Page{Random} = false)
Place i on Page{Random}
Set Page{Random} = true
12:45 AM
This also works for me, but this doesn't work (using xelatex):

While this works:
In the first example, a+b is rendered in mathmode, but with backticks on both sides. I've no idea what is happening :P
@Kasper add \show` after begin{document} and it's easy to see why
unicode math makes backtick active itself and then does all its setup at begin document so the definiion of `\` ` is not yours but `=\long macro:
->\int_zero:N \l_um_primecount_int \um_scanbackprime_collect:N \um_backprime_si
ngle_mchar .`
aah okay
So if I put my definition after begin document I override unicode math
@Kasper yes but overriding random bits of big packages isn't always a good idea:-)
1:23 AM
I have a rectangular area, I would like the bottom 1 cm and the left 1cm to fade out
any ideas?

Relevant ad :)
@Aditya and, I've seen that page before :D
Perhaps the ad system is smart
nah, just brute force
that ad comes up on tex.SE prolly more often
or only on tex.SE
and there aren't that many ads (I've seen this particular one several times I think)

Yesterday, I was jogging and saw a goose in a house. :)
10:03 AM
Hi @StephanLehmke! We miss you!
@PauloCereda Hi! I'll try to come here a bit more often again. I was assigned some non-TeX related stuff lately, but I'll be doing a bit more "real" work again fom now on :-)
Nice to see all seems to be working as usual round here - glad to be back!
btw, does anyone have a working environment for TeX.SE contributions on IPhone?
I tried it out yesterday, but from Safari the site is cumbersome to use, and I didn't manage to log in to chat. Also, I'll need a TeX installation for trying examples :-)
10:20 AM
@StephanLehmke As for the chat login, there was a recent meta question: meta.tex.stackexchange.com/questions/3927/…
@StephanLehmke I know @AndrewStacey has experimented with TeX on an iPad (tex.blogoverflow.com/2012/09/i-tex-therefore-ipad-reloaded), don't know about iPhone.
Hi everyone
@ForkrulAssail Hello.
Nice photos @TorbjørnT.
@ForkrulAssail Oh, you mean Flickr? Thanks!
@PauloCereda Is there a \jobname equivalent for arara's clean rule?
10:29 AM
@cgnieder hm tell me more. :) What are you thinking of? :)
@PauloCereda Ideally I'd like just to list the extensions (aux, log, ...) that I want removed. Something like
% arara: clean: { files: [ \jobname.aux, \jobname.log ] }
@cgnieder Ah I see! Gimme a minute, I have an idea. :)
@cgnieder: here you go, Clemens:
% arara: pdflatex
% arara: remove: { items: [ aux, pdf ] }

The rule:
identifier: remove
name: Remove
command: <arara> @{remove}
- identifier: remove
  default: <arara> @{isNotEmpty(item, isWindows("cmd /c del", "rm -f").concat(' "').concat(getBasename(file))concat('.').concat(item).concat('"'))}
@PauloCereda Nice! Thanks :)
@cgnieder My pleasure. :)
11:36 AM
Dear mathematicians:
\left| \bigcap_{e_i \in E_{s_j}} \{ \pi_3(e_i) \} \right| > 0
This looks ugly to me. :(
11:49 AM
@PauloCereda Yes, it is; use \biggl and \biggr
12:00 PM
@egreg Looks way better, thanks! :)
@PauloCereda It's very common: \left\right with big operators having limits wants to cover the limits and the result is not very appealing. I didn't even try the input, the answer is standard and already given by Knuth himself in the TeXbook (page 149).
12:13 PM
@egreg Ah. :) I didn't reach that page. :)
12:47 PM
@PauloCereda @egreg Is it strange that I would use \bigl\{...\bigr\} as well in this case?
@tohecz :)
@PauloCereda I like my delimiters to increase step-by-step when reasonable ;)
@tohecz Sounds like a plan. :)
CS people just go, *ooh math thingy here! Must be important! :)
@PauloCereda LOL
1:05 PM
@tohecz Yes. ;-)
@DavidCarlisle: get M an Xbox One or a PS4 for Christmas. :)
1:55 PM
More math help, please. :)
Any hints on how to improve this code:
\bigcap_{o_i \in O_{s_j}} \bigcap_{c \in I_{s_j}} \{ \pi_1(o_{i,c}) \} = \emptyset
@PauloCereda Not using double indices?
@egreg I... am a math newbie. :) I don't know how to do that in LaTeX. :)
@PauloCereda It's a notation, not LaTeX, problem. If you use $O(s)$ instead of $O_s$, then the double index disappears.
But it depends on several other factors deciding if the notation change is good.
@egreg Ah I see.
@PauloCereda Have I already said that I don't like Čajkovskij?
Well, I confirm it. :)
2:07 PM
@egreg I'd remember that name for sure! :) Then, no. :)
@egreg :P
Who's that guy?
@PauloCereda Maybe you know him as Чайковский
@egreg There's a mirrored N. :P
@PauloCereda pt.wikipedia.org uses that spelling.
@egreg We are dumb. :)
I hate his piano concerto #1.
@PauloCereda The translitteration Čajkovskij is based on the Czech alphabet. The one used in Portuguese is based on French
2:12 PM
@egreg Thank God. I wouldn't be able to remember all those letters. :)
@PauloCereda The “Sledgehammer Piano Concerto”?
@egreg LOL
@PauloCereda Copyright by @AlanMunn
2:48 PM
@PauloCereda @egreg Something musical we all agree on!
@AlanMunn Yay!
3:27 PM
@egreg Do you know how FontBook automatically resolves duplicate fonts? (I.e. how it chooses which one to keep?)
@AlanMunn I noticed that it does something about duplicates, but I didn't really understand which one it chooses.
@egreg Me neither. It finds lots of duplicates for me, but I have no idea whether it's safe to let it resolve them automatically. And the manual resolution doesn't seem to let you choose which one to make active, unless I'm misunderstanding the interface.
So the last South Park episode is about Black Friday. I really don't get US things.
@AlanMunn I had some and resolved them manually.
3:58 PM
@egreg Did you figure out a way to change an inactive version to the active version?
@AlanMunn No. But if you remove the active version, the inactive one should be resurrected.
4:09 PM
@AlanMunn I checked and there was a duplicate. I had Neo Euler both in my Library and in the global Library, so Font Book decided the personal copy had precedence. I removed manually the one in my Library, then left clicked on the only (inactive) font remained in Font Book to activate it.
@AlanMunn I guess it looks also to the version number, but in this case they were the same.
4:25 PM
@egreg Maybe I don't understand what they mean by "Resolve Manually". I thought that it just means I click on each font one by one, but I suspect it means that FontBook actually does nothing at all. The Apple support page is maximally unhelpful. I think I'll ask on the Mac SX site.
@AlanMunn It offers you to remove the already inactive copy.
@egreg But if the inactive one is a higher version than the active one, I would want it to switch the two, but that's not what happens, as far as I can tell.
@AlanMunn No, it doesn't. You have to trash the active copy and reactivate the other one.
@egreg I see. So it's a very dumb system.
@AlanMunn Or we're dumb. ;-)
4:33 PM
@egreg That is a distinct possibility. Nah. I'll go with it's the computer.
Fonts fonts fonts fonts
This is a really nice question: perfectly stated and illustrated. What every question should be like.
Q: Tikz, rotate, how to specify a point as rotating center?

ColinZWhen I use rotate on a node, it seems to be rotated against its west(As in figure (up) and (middle)), however, what I meant is to rotate it against its center, like (bottom) of figure shows. I didn't find such a parameter in manual.... \begin{tikzpicture} [sampleA/.style={text width=1cm, tex...

@PauloCereda This is the one I prefer
@egreg Oh my!
@egreg Planning to move to Ethiopia any time soon?
4:39 PM
@AlanMunn Armenia?
@egreg Oh, my mistake. It looks like the script for Amharic a bit. (I didn't check).
@AlanMunn For some months I shared my desk (young fellow of the department, you know) with another guy from Bulgaria. He kept notes in a writing I couldn't recognize: it was, in fact, Armenian.
@AlanMunn Of course, the guy's family name ends in “-yan”.
As you can see, they are somewhat similar in style.
Also similar: Georgian.
@AlanMunn Yes, there are some style similarities.
@StephanLehmke I guess Georgian alphabet was derived from Armenian; or the other way around, depending on what side of the border you live.
5:10 PM
Q: Using LaTeX to keep a diary

user1428640As the title implies, I would like to use LaTeX to keep a personal diary. I've been dumping my entries in a single file which has become unwieldy over time. Ideally I'd find a package (or collection of shell scripts) which assists me in maintaining a consistent directory structure and automatic...

I won't upvote any answers that don't have Dear diary in it.
1 hour later…
6:22 PM
How to do indented quote block?
@hhh \begin{quotation}...\end{quotation}
@hhh That's a completely different thing.
@hhh That page is rubbish. The "dangerous” remark is foolish: with {\raggedright text} you don't get a ragged right paragraph. Just try with some lines instead of text.
roger, using now quotation thing.
6:40 PM
It happened again: a question on symbols closed as duplicate without the slightest mention in comments on where to find what the OP wanted.
Q: \nearrow and \swarrow together

user2933038I'm trying to get an arrow that has an arrow head pointing north east and south west, so like \updownarrow but rotated. I can't seem to find this in LaTeX at all. It has to go inside an equation environment. Any ideas?

@egreg If I remember correctly, there was a comment mentioning \neswarrow from MnSymbol, but as it also mentioned the 'duplicate' it was automatically deleted when the question was closed.
@TorbjørnT. Do you consider "the symbol is available in MnSymbol" a valid solution? I don't.
@egreg Not ideal, I agree, but there was something at least.
@JosephWright I expected at least a comment by a moderator to my question in Meta:
Q: Wrong closure as duplicate

egregToday I got an upvote for my answer to Rotated $\ltimes$ symbol which has since been closed as duplicate of How to look up a symbol or identify a math alphabet? Looking at the question it is apparent that looking up for a symbol is unsuccessful. One finds similar symbols only with MnSymbol o...

7:38 PM
@egreg The OP got help, he said "worked a treat". After the closure, incoming googlers or readers are now pointed to the canonical symbol question, which is good. I even undeleted the automatically deleted comment to the question. Any reason to add answers to the existing two? I don't think so, so I don't have a problem with closing, and the reason matches.
8:21 PM
@StefanKottwitz No, it's not right. There can be better way to get the symbol that nobody could add.
@StefanKottwitz That's why I opened a discussion in Meta. But none of the moderators felt like to express an opinion: which means they have none. And I don't like it.
Twenty votes on the question, no answer. Do you think it's good?
8:39 PM
2 hours later…
10:21 PM
@egreg: You answered a question once about cycling through (section heading) colours. Do you remember?
@Werner Just add \ifnum\value{colorCounter}=7 \setcounter{colorCounter}{0}\fi at the end of \@sectioncolor
There was a newer alternative to the mylatex package. Can someone remind me of the name of this newer package?
Got, it, mylatexformat
11:23 PM
@AlanMunn Do you think that Cave canem in a comment can be understood?
@egreg Probably not. The state of general education these days is deplorable. :)
@AlanMunn @PauloCereda will certainly know what it means.
@egreg At least in English, I don't think it's actually a well known expression. (Neither the Latin nor its translation.)
@egreg Beware of the dog? :)
@AlanMunn Hic sunt leones, maybe?
@PauloCereda Yes!
11:26 PM
@egreg woohoo!
@PauloCereda How do you say in Portuguese?
@egreg Cuidado com o cão. :) It's a common sign in some houses. :)
@egreg Not really. I'm trying to think of what the equivalent English expression would be.
@PauloCereda We have Attenti al cane
@PauloCereda But that just has a literal meaning, right?
11:30 PM
@AlanMunn Yep, I can't think of another expression.
@PauloCereda But the Latin has a non literal meaning, I think.
@AlanMunn I have the same impression. :)
@AlanMunn: I can only think of cutucar a onça com vara curta. :)
I think for Hic sunt leones people would use terra incognita instead.
@AlanMunn pisar em ovos, perhaps?
@PauloCereda We have "Don't poke the bear" (onças being somewhat rare around here).
@PauloCereda I think we say "walking on thin ice" (although we also have "walking on eggshells").
11:38 PM
@AlanMunn Don't mention the war? :) (Fawlty Towers reference)
@PauloCereda Sorry, I'm not enough of a Fawlty Towers aficionado for that.
@AlanMunn Oh. :( I think I watch too much television. :)
Let's see if @JosephWright appears. :) After all, it was a British show. :)
