@DavidCarlisle Seen on c.t.t: (1) Hardly anyone is using picture anymore

@JosephWright LOL

9:37 AM
Hey guys, is anyone using Btrfs in production? I'm using it in my laptop for about 1 1/2 year, but never on my workstation.

9:50 AM
Nothing can beat the power of a pie! :) Congrats and merry Christmas! :)Paulo Cereda 9 secs ago
@egreg: Palmeiras brought an interesting player for next year's season: do you remember Zé Roberto? He played for Bayern.

10:10 AM
@PauloCereda Yes, I remember him.

10:22 AM
@JosephWright don't believe what you read in the internet:-)

@DavidCarlisle Don't worry, I don't :-)

@DavidCarlisle So you don't use emacs after all. Hmmmm.
:)

@PauloCereda really I use vi but I'm too ashamed to admit it, don't tell anyone

@DavidCarlisle And I'm an hardcore emacs at heart. <3
@David: why do I think we will use these quotes of ours later on for blackmail purposes? :P

10:39 AM
@PauloCereda If you always tell the truth you have no fear of blackmail

@DavidCarlisle Even in the internet? :)

@PauloCereda so, what's the shortest answer to "Why do they speak Portuguese in Brazil" as asked while arranging our cards.....

@DavidCarlisle They were colonized by the Portuguese. :)

@DavidCarlisle Aliens

Actually, imprisoned and slaved, but that's too long for a card. :)
@JosephWright LOL I wub you.

10:45 AM
@DavidCarlisle You didn't say it has to be correct, just short

@JosephWright This is deliciously evil. :)

@DavidCarlisle If you use vi, you must be a hacker, and are therefore a "person of interest"" to GCHQ. Please do not bring any of your digital equipment to my house, as you will be denied Wifi access.

@Brent.Longborough I d*mn well hope at least some of us have managed to be 'of interest' to them!

@JosephWright yes, but.., I meant "short" as in accurate but avoiding a treatise on European colonial history while putting up Christmas decorations

10:48 AM
@DavidCarlisle :-)

@David: and we don't speak the European Portuguese, but rather Brazilian Portuguese. It's quite amusing (not mentioning ironic) to see Portuguese nowadays being a synonym to Brazilian Portuguese. :)

@JosephWright Nah, those gov.uk people don't use TeX, they use WordStar™

@PauloCereda we are used to that, there is a country North of you that doesn't speak proper English either

@DavidCarlisle :)

@Brent.Longborough Interesting

10:52 AM
@Brent.Longborough Eles pegam o comboio ou o autocarro? :)

@DavidCarlisle Treaty of Tordesillas
@DavidCarlisle Is this short and accurate enough?

@JosephWright Of course, like many major corporations, they also use Excel for it's renowned word-processing and typographic capabilities.

@egreg ooh I forgot about that one!

@Brent.Longborough If they are using WordStar then I'd expect 123, surely

@PauloCereda I don't know, I can't speak Lusitanian Portuguese

10:53 AM
@Brent.Longborough :)

(P.S. I have used WordStar on a CP/M machine)

@JosephWright Visicalc

@JosephWright Oh my, I love Lotus 123!

@JosephWright With punch cards? ;-)

@Brent.Longborough Could be, yes
@egreg Nope, 8" floppies, proper Winchester disk, etc.

10:55 AM
@JosephWright :( Using punch cards is a very entertaining experience: there are vastly more ways to make something fail.

@egreg Almost certainly

@egreg Don't knock it, I once wrote a markdown-type language for text processing from punched cards. Read the cards, reformat, and print. In 360 Assembler. Those were the days. "Nostalgia ain't what it used to be"

@JosephWright I misread Manchester disk, oopsie.

@egreg I have used a system with no screen, but that was 'cheating' (the built-in screen had died so we had to make sure we typed in exactly the right set of commands)

10:57 AM
@egreg The big issue for me with punched cards is finding a punch machine with lower-case support on the keyboard

@Brent.Longborough A tech version of those four yorkshiremen. :)

@Brent.Longborough You need bigger cards for them

Meanwhile, anyone understand tex.stackexchange.com/questions/219051/…? I can't see how the code in the question relates to the comment on the aim

@egreg LOL. You also needed a mixed case print chain

@JosephWright The explaining comment is rather involved.

11:00 AM
@egreg Yes, but the doesn't even attempt to draw a box
@egreg Or use any of the variables created
@egreg Or work at all (it's text width not \textwidth)

@Brent.Longborough The teletype stops and you change the printing head.

Nowt like a nice bit of EB Garamond before breakfast
@egreg I didn't have a teletype, only a line printer

@Brent.Longborough :)

@Brent.Longborough Very nice indeed! :)

@PauloCereda You can see the whole thing here.
@PauloCereda (Don't forget to zoom in to 100%)

11:09 AM
@Brent.Longborough An email address with ligatures a day keeps the spammers away

@percusse Right. Unfortunately, my real name has no opportunity for historic ligatures... Snif!

Good maen

@ChristianHupfer 'lo

@yo': I see, Paulo infected you with his 'brev 'irus ;-)

@ChristianHupfer l'l :D

@ChristianHupfer 'yo

@PauloCereda hey! :D

1:37 PM
@yo' yo! :)
^^ ooh yo-yo

@PauloCereda: Oh my ...

:)
@ChristianHupfer Who's on first sketch all over again. :)

@PauloCereda: Don't know that

@PauloCereda: Completely unknown to me...as to most Germans anyway ...

1:42 PM

@ChristianHupfer whereas black and white American sketches about some sport totally unintelligible to anyone not from there are common knowledge in Brazil (it seems:-)

@DavidCarlisle: Baseball, I assume... As well as American Football ;-)

@DavidCarlisle Nope. :)
@David: quite amusing, the majority of Brazilian have no idea about baseball, Abbott and Costello, Monty Python, etc. :)

@PauloCereda neither do I :)

1:59 PM
@PauloCereda You have to realise that for most of us here you are our main insight into Brazilian culture, are you suggesting we are getting a warped view?

@DavidCarlisle Oh my!

2:56 PM
@David: you know our capital? Don't you dare say it's Buenos Aires, or else. :)

@PauloCereda Lisbon

@DavidCarlisle Oh my!

@PauloCereda some document @egreg pointed me at earlier today seemed to imply you were in the half of the world not ruled by Spain.

@DavidCarlisle Plain TeX document? :)

@PauloCereda might be an interesting plain tex project

3:01 PM
@DavidCarlisle Fraktur? Some German typeset that for them. :)

@PauloCereda 1494, I guess it's hand written?

@DavidCarlisle Nah. :)

@DavidCarlisle Chancery style!

@egreg :)

3:18 PM
Can somebody help me to format better this equations? :)
\begin{align*} \lim_{n\to \infty} \frac{(n+1)\ln(n!)-2\ln(2! \cdot 3! \cdot \ldots \cdot n!)}{n^2+n} = \\
=\lim_{n\to \infty} \frac{(n+1)\ln(n!)-2\ln(2! \cdot 3! \cdot \ldots \cdot n!)-(n\ln((n-1)!)-2\ln(2! \cdot 3! \cdot \ldots \cdot (n-1)!))}{n^2+n-((n-1)^2+(n-1))}\\
= \lim_{n\to \infty} \frac{(n+1)\ln(n!)-2 \ln(n!)-n \ln((n-1)!)}{2n}\\
=\lim_{n\to \infty} \frac{(n-1)\ln(n!)-n \ln((n-1)!)}{2n}=\clubsuit.
\end{align*}
If somebody have time and will offcourse.

@Cortizol it's far easier if you post a complete document (if only to confirm target linewidth) in a question on the main site, but just looking you have an align with no & alignment points which seems strange

@DavidCarlisle I use \usepackage[top=1.5cm,bottom=1.5cm,left=1.9494cm,right=1.9494cm]{geometry}
@DavidCarlisle Yes, I didn't put &. Problem is that second equation is too big, but, I will separate that fraction in two parts, that is probably easier solution
But it looks ugly for me to write a+b/c+d=a/c+d + b/c+d, to be honest.

@Cortizol Long math formulas are unreadable
\documentclass[a4paper]{article}
\usepackage[top=1.5cm,bottom=1.5cm,left=1.9494cm,right=1.9494cm]{geometry}
\usepackage{amsmath}
\begin{document}
Consider
$a_n=(n+1)\ln(n!)-2\ln(2! \cdot 3! \cdot \ldots \cdot n!), \qquad b_n=n^2+n$
and that
$\lim_{n\to\infty}\frac{a_n}{b_n}=\lim_{n\to\infty}\frac{a_n-a_{n-1}}{b_n-b_{n-1}}.$
Now we can compute
\begin{align*}
a_n-a_{n-1}
&=(n+1)\ln(n!)-2\ln(2! \cdot 3! \cdot \ldots \cdot n!)
-(n\ln((n-1)!)-2\ln(2! \cdot 3! \cdot \ldots \cdot (n-1)!))
\\
&=(n+1)\ln(n!)-n\ln((n-1)!)
OK, there's a = in excess in the last line.

4:04 PM
@DavidCarlisle WOW!

@egreg I left it to you, but then I couldn't resist I had to see what it looked like, then I wish I hadn't:-)

@DavidCarlisle Impressive!

This question appears to be off-topic because it is not a UX question, it is about... giving colours a name beginning with B, or something. Please read the TOUR page to see what this site is about. — JonW ♦ 49 secs ago
Via mod chat, a totally bonkers question

4:43 PM
@JosephWright Maybe someone wants to win some sort of children's game. :)

4:55 PM
@egreg Thank you. That is really elegant solution. You add an extra line to explanation, great :)

@Cortizol Divide et impera said the Romans: “divide and conquer”.
@Cortizol The reader can concentrate on the main topic (the numerator).

5:08 PM
@egreg destroy and conquer :)

@yo' They didn't necessarily destroy towns, if they submitted.

@egreg that's an almost empty set :)

@yo' Oh, no! Several towns decided they couldn't resist. Maybe after having seen their neighbor's town disappear. ;-)

@egreg yeah I know

6:04 PM
@JosephWright I am sitting outside the library right now checking mail, but the color question made me laugh so hard, that i am feeling comfortabely warm.

6:28 PM
@Johannes_B :-)

@MichaelDell: sir, could you please shutdown your Brazilian subsidiary? They are being negligent with my claims for a very long time. :(
It would be awesome if this dude replies. :P
I was gonna say burn down instead of shutdown. :)

6:43 PM
@PauloCereda lol. Well, I've never trusted to these next-working-day services.

@yo' In my case, two-weeks service. :)

@PauloCereda oh

7:02 PM
@PauloCereda What happened?

@JosephWright A computer purchase. The product got damaged mid-delivery by the carrier, they sent me another, but the carrier hasn't reached here yet. They had to deliver my new computer at least 5 days ago.
But their call center is absolutely the worst thing ever. No one is even close to being helpful.

Hello everyone

@GigiButbaia Hello

I have one problem with latex document, when I try to compile it as pdf (I'm using TexNicCenter), I get this error: "pdflatex> I can't find file 't8menc.def'" what does that mean? (I'm using babel package)

@GigiButbaia That something is trying to load fontenc with an encoding called T8m

7:20 PM
Here's code that I'm using:
\documentclass[journal]{IEEEtran}

\usepackage{amsmath,fourier,stmaryrd,graphicx,float,wrapfig}
\usepackage[georgian]{babel}
\usepackage{fontspec}
\setmainfont[
Extension=.ttf,
UprightFont={*},
BoldFont={*-Bold},
ItalicFont={*-Italic},
BoldItalicFont={*-BoldItalic},
]{DejaVuSerif}

\title{something}

\setmainfont[
Extension=.ttf,
UprightFont={*},
BoldFont={*-Bold},
ItalicFont={*-Italic},
BoldItalicFont={*-BoldItalic},
]{DejaVuSerif}

\begin{document}
\maketitle

anyway, I I think the problem is with miktex which renders pdf document. I have tried updating miktex but it said that server didn't respond

@GigiButbaia 'Works for me' with an up-to-date system, but no weird encodings. As you are using fontspec it will be EU1/2 (XeTeX/LuaTeX)

Does anybody know offhand how to vertically center just a few cells in a TikZ matrix? Adding nodes = {anchor = center} vertically centers all cells, which is not what I want.
Can't immediately find an answer just searching the site.
