@egreg Good answer. :)
I don't see how it could ever be constructive
Another possibility is to migrate this question to SciFi. After all, Marvel has a "WHAT IF" series which tells a story from another dimension. :)
@PauloCereda Or "it would be iTeX ^G" (The ^G, of course, stands for "ring the bell")
@egreg LOL let's add a comment: "iTeX ^G was introduced in 2010, it's fairly recent". :)
Jesus Christ, that question already got 3 favs!
@egreg @PauloCereda itex.de (background sound)
8:05 PM
@Qrrbrbirlbel OMG!
I knew the Germans were behind it. <3
Why every time I read that question, I think of Aho, Sethi and Ullman? :)
8:40 PM
@PauloCereda Why not "Alpher, Bethe and Gamow"? :) This is the best trio of authors in history.
@egreg Indeed. :) Those three guys are famous in CS for the Dragon book. :)
This might be a good addition for kantlipsum
Q: Lipsum text generator for analytic index

FormlessCloudIs there something like lipsum package but for the analytic index?

@egreg Cool! Via a package option?
@PauloCereda I guess so.
8:46 PM
haha, question with 4 upvotes and 3 favourites gets closed as NC :) (NB: I agree with the closure.)
@paulo Now every time I see you in this room, I think of ducks. =)
@JasperLoy er... thanks, I guess. :)
@percusse I wasn't expecting them to turn green!
@PauloCereda :-)
@percusse I've been fooled! :P
9:43 PM
TL based on OP's last comment.
Q: Tikz graph layout algorithms and loading file using pgfplotstable

user1632456I am trying to enable layout algorithms in CVS-version of PGF. Following code can be compiled by LaTeX. \documentclass{article} \usepackage{tikz,pgfplotstable} \usetikzlibrary{graphs} \begin{document} \pgfplotstableread{mymatrix}\dataSampleMtx \tikz \graph { { [clique] a, b, c }, { [clique] d, e...

@percusse Voted. :)
@PauloCereda Appreciated :)
@percusse Now buy an XBox!
@PauloCereda I've played GT again in my friend's place. I'm really susceptible to get addicted to that.
Actually that's why I'm trying to switch to Linux: to limit things that I can do with a computer :)
@percusse One bad thing about Xbox: the DVD drive. One thing good: the controller! :)
9:46 PM
@PauloCereda Can't we just replace it with something else?
@percusse Nope. :(
@PauloCereda I mean really opening it up and soldering the !*@? out of it.
@percusse ooh brute force. I like it. :)
@PauloCereda engineer alert...
@percusse Trust us!
9:51 PM
@paulo Do you have any idea why I hear a very loud sound sometimes when I put in a Linux live DVD or TeX Live DVD into the DVD drive? Is some kind of untarring going on? The sound usually stops after a while.
@JasperLoy I'm not sure, but I think it's just a buffering thingy going on. :) Most recent Linux distros mount the media automatically and provide some features on the content, like thumbnails, preview, etc. :)
@JasperLoy Is it always the same DVD?
@percusse The same thing happens with different DVDs. But the weird thing is that sometimes there is no sound with the same disc.
@JasperLoy Well, there is a hardware control algorithm working regardless of data and it's usually designed to get the reference marker right on the data track. It even matters how you align the DVD initially but I can't be sure. It can be either reading the same chunk over and over again for error correction or just a warped plastic. So depends on the sound. Do you have a MWE ? :)
@percusse Hehe, none can be provided in this case. It is not easily reproducible. =) You have to be here with me to see for yourself.
9:58 PM
@percusse o.O
Now the sound is really scary I must say. Sometimes I think it is going to explode.
At first I thought it is overheating, but when I touched it the temperature seems normal.
Also the data structure matters because the drive is designed to keep the velocity of the data track relatively constant angular velocity is changed depending on the position of the reading head. Normally you have the inner tracks have most of the data so it starts very fast to keep up and slows down later.
such as the local FAT etc. so it needs to read those very quickly.
but if the DVD plastic is warped at higher speeds it starts to resonate making an audible noise.
then things get complicated as in the control algorithm there is a procedure to implement a varying notch filter bla bla some technical mambo jambo.
@percusse LOL
@percusse Wow, you must be a DVD expert! Yes I think that's what's going on.
10:04 PM
@JasperLoy I wish :) It's just feeding back the frequency of the disturbance no magic involved.
And that we know from the rotational speed.
The rest is some clever engineering, if you remember the now-dead gadgets of jog-free CD walkmans they had even better algorithms to buffer the songs etc.
but Creative killed the fun with MP3 players.
I need 200 more points to get 2k. =)
@PauloCereda Done! Now kantlipsum can generate an index!
Now this is definitely something to read : arxiv.org/abs/1202.4212v1
@egreg Wow! Fantastic! Can we have a preview? :)
@percusse I don't know anything about this, but the title sounds like something of an internet prank.
10:11 PM
@JasperLoy Actually the rest is the prank. Finally somebody is honest and courageous enough to say it out loud. :)
@egreg I can see that this will go into imakeidx manual :)
@egreg How nice! What's the secret? :)
@percusse "What is a "chord"? What is a "key"? WHAT THE HECK ARE THEY TALKING ABOUT!" LOL
@PauloCereda I just chose a word or phrase from each paragraph. The index option enables writing the entries.
@percusse: in other news, when I organize a TUG meeting, I'll put a few consoles and TVs in the hall for TeXers to have fun during breaks. You are in the gaming committee already. :)
@egreg Neat! :)
10:15 PM
@PauloCereda Awaiting orders, sir!
@percusse Should we let them play CoD or some zombie game? :)
@percusse: think of Karl Berry, Barbara Beeton, @egreg and @DavidCarlisle playing Mario Party in the Wii. :)
@PauloCereda The Fall of LateX III
@percusse oooh! :)
@PauloCereda Surely barbara would win.
@egreg Indeed. :) I'm afraid David's area of expertise is Lego-related. :)
10:20 PM
@PauloCereda My area is playing cards (although I'm a bit rusty).
David probably would choose to play from Emacs. Somehow I feel that he can manage to do it.
@percusse LOL
@egreg I don't know how to play cards. The only game I knew, I already forgot. :)
@PauloCereda Briscola and tressette are my games. Never had time to practice bridge.
@egreg Do you have a Briscola face?
@percusse What do you mean?
10:23 PM
@egreg "Poker Face" from Lady Gaga. :)
@egreg as in Poker face...
OK, our bot has triggered the following video:
Oh no...
It's polka time!
Po-po-po-polka face!
@percusse I don't know what you're talking about. I think I've heard about this girl, but no more than her name.
10:26 PM
@egreg No no it's a common phrase... As most professional Poker players have a Poker Face to hide their bluff or excitement so others can't read it from their face but anyway.... that didn't go as I've planned heheh.
@egreg: I know Briscola (we have a variant here named Bisca), but I've never heard of Tressette. :) The Wikipedia shows a very beautiful deck. :)
I know how to play chess, but no one around here knows it. :(
@PauloCereda The principle of Tressette is similar to Bridge, but there are no atout. You must follow suit, the highest rank card wins. But the ranks are, in descending order, 3, 2, A, K, Q, J, 7, 6, 5, 4 (the deck has 40 cards). For the score, the ace counts 1, while 3, 2, K, Q and J count 1/3 (remainder discarded). So the maximum score is 10.
@egreg Cool! It seems very interesting. :) Out of curiosity, how many cards does the Italian deck have?
Players are supposed to be silent; the tradition is to use the way to play a card. For example, if the first player slams a card, it means that he/she wants his/her partner to play the highest rank in his/her hand and play again the same suit.
@egreg aah the signs! We have some cool indications here too! :)
10:38 PM
Our decks have 40 cards. And they are different from region to region. The suits are called "spade", "denari", "coppe" and "bastoni" (corresponding to spades, diamonds, hearts and clubs).
@egreg Interesting. :) Our deck has 52. :)
@PauloCereda Here is a sample of cards from our region
@egreg They look so beautiful! Ours is ugly. :(
Actually the 10 is bogus (it's used in Friuli, not in Veneto), but the cards are the same.
The four head card is the "Fante di spade" (J of spades).
Bottom left is the "Asso di spade"
Very nice!
10:43 PM
This one is the "Asso di bastoni"
Players not accustomed to our cards can confuse "bastoni" with "spade"
Oh I see, bastoni is the clubs! :)
@PauloCereda Yes. the same. But "spade" is "swords", not "spades".
@egreg ah got it! :)
Those decks are marvelous.
@PauloCereda "Denari" is "money"; "coppe" is "cups".
@PauloCereda What card is in the upper right of the group above?
@egreg Hold on, I'm gonna guess it right! :)
King of spades!
@egreg: Did I guess it right? :)
Our deck. :(
10:51 PM
@PauloCereda No! "Re di coppe"
@PauloCereda Anonymous French cards. :P
@egreg Oh. :)
I am hitting a bug, pastie.org/5059330, related tex.stackexchange.com/a/77641/2956. I find it hard to find some missing tag or something, ideas for this debug situation? I am using the Emacs validate-TeX etc tools but it suggests "no mismatch" but but it does not check tags, how would you debug this?
@egreg Exactly! :)
@hhh You shouldn't use align inside of equation; align by itself is sufficient.
@hhh I already responded with a comment. :)
10:54 PM
@hhh But in those cases it seems that aligned should be used inside of equation (so only one number will be assigned)
@egreg: I have a magical deck, in which you can get a certain card from any position from the deck. :) Do you know the secret? :)
@PauloCereda In the movie "Totò, Peppino e i fuorilegge", Totò always wins by guessing the card that Peppino gets from the deck. All cards are "Asso di bastoni".
@egreg ooh that's dirty. :)
@egreg: the trick is very clever, actually. The card format is not rectangular, but trapezoidal. :) If you have all cards aligned (with both big and small bases at their corresponding sides), by puting a card in the "other" side, that is, with its small base in the big side, will make the card protrude from the deck - very difficult to see, but easy to feel it with the fingers. :)
I got it very nice https://twitter.com/heoaLov/status/257618062302404609/photo/1, I am unsure whether I should use this many amount of equation -labels, perhaps it does not matter or? Anyway getting no err now, http://pastie.org/5059390, happy about that :)

Thank you.
@hhh May I add that parenthesis around fractures are not needed (1/A).
Furthermore, you can freely use spaces (or tabs) to indent and rearrange the formula without any effect on the output.
11:08 PM
@Qrrbrbirlbel I have tried to write as succintly as possible to learn the basics :)
(but for some reason wanting to have the parenthesis around fractures, for readability)
Hm, for me, too many parenthesis reduce readability.
(Especially redundant ones.)
@Qrrbrbirlbel That reminds of my Lisp phase. Those were hard times. Those were happy times. :)
Quick question: With `xcolor` I can modify the color even inside in verb text


Is it possible to make the `verb` text italics or bold?
11:24 PM
@Werner I'm never sure if I should edit good additions from comments to my answer (it can be seen as "stealing"). But often the author is going to delete their comment after I implemented the idea.
Also \string^. — Werner 5 mins ago
@Qrrbrbirlbel I think you should add it and I'll delete my comment! :)
Is there a common rule? Clean answers vs full authorship?
@Qrrbrbirlbel Ok, I tried to make it less redundant here.
(with arrows, you can compare the old and the new without extra parethesis, less beta reductions :P)
@halirutan newverbs can help. :)




Hello \myverb|blue| world

@Qrrbrbirlbel There is no clear rule AFAIK. Some users feel like they want to contribute a full answer regardless of how small the addition is.
If the answer could fit in a comment, then it is most likely suitable for a comment.
11:28 PM
@PauloCereda And can I set the fontweight or the slant with that?
Something like \bfseries\verb+Hello+ does not work
@halirutan Good question. :P I thought we were talking about colors. My bad. :) I'll take a look. :)
@PauloCereda Colors work nicely ;-)
Moreover, I have a large amount of reputation, so I don't mind give credit to others for using small additions of mine. If need be, you can make a contribution in the edit summary...
@Qrrbrbirlbel I actually like to have less parenthesis, I found bugs immediately from my writing :D
@Werner (I added your comment. Credit within the edit summery and in the answer itself.)
@hhh Another thing: you have stuff like a/b sqrt(b/c) h. I would write \frac{ha}{b} \sqrt{\frac{b}{c}} (no factors behind the root).
(But this really is nitpicking/stuff to do after you finished the whole document.)
11:36 PM
@Qrrbrbirlbel Thanks.
And anyway, nothing that helps you to export good TeX from Mathematica. :(
@Qrrbrbirlbel For good Tex from Mma you need to do a lot work by yourself.
Nothing which is done in 5 min.
After "100 ways to draw a black line in TikZ" there should be "100 ways to typeset an arbitrary character in (La)TeX". And certainly, someday someone will write a package … :/
@halirutan The Mathematica related discussion stems from:
Q: Formatting LaTeX-dump from Mathematica equations for A4-paper without manual adjusting?

hhhI asked this question here in Mathematica.SE but they encouraged to ask also on this site. How can make this writing process easier from Mathematica to LaTeX? Please, note that I have a lot of variables and I want to make them visible to the reader, I am not much interested how but not over th...

@Qrrbrbirlbel Yes, and we have several questions on Mathematica.SE about it.
The problem is, that this in the same complexity that "formatting code" automatically.
It does kind of work, but not good.
For a LaTeX-export you maybe have to start from the roots like Leonid did
And there is always the question of "good". There are so many styles and ways to accomplish something.
Question like "How to align the following equation" gets 5+ answers. One better than the other.
11:43 PM
Yes, formatting source code is in this case easier. The work stays the same.
@Qrrbrbirlbel Yes but $h$ is a key term that I want to emphasize, I even considered adding there extra parenthesis to make it more clear from other vars.
@Qrrbrbirlbel If you read forward, you can see that I call other junk with dummy vars later to make $h$ more distinct.
I know it is confusing with square-roots but not knowing better way to make it distinct and less loaded
(When I stopped using too many pars, it was much easier to debug... and fix mistakes at the cost of readability ofc in a way)
@hhh Huh, I see. You could use bold/colored maths, but I don't recommend it. You could at least introduce a little space \, before the "important" variables.
@Qrrbrbirlbel how is that done? [space][space]?
No, as I posted: \,
Didn't I already guide you to the amsmath documentation? ;)
