@AlanMunn @egreg ref chat.stackexchange.com/transcript/message/16578711#16578711 , thanks. This is what Mathematica generates :(. I'll try to see if there a work around it. If not may be I can ask for help on main site if you think this question might be useful.
@percusse I asked about it in the Mathematica forum. But since it seems like a Latex bug, not sure what else to do about it. Send email to Wolfram Research. Meanwhile, I was wondering if there is some trick or something I can do in the preamble to patch this so I can compile my latex file, since I do not want to manually fix/edit each case since this script runs many times. Would this still make it valid question to ask here?
@percusse sorry, I meant it is latex bug in Mathematica generation code. Not a Latex bug is texlive. Yes, it generates the wrong code. But the question if there is a way to write a macro that checks for \left\left.... and re-defines things correctly so I do not have to do manual edit/fixing each time I generate the Latex. So it is a Latex question.
If I want for Wolfram to fix this, it will take years may be, who knows.
@Nasser Don't get me wrong you can still ask for it but I would stay away from nesting the problem into deeper macros. When things break down, it's harder to find the cause that way.
@percusse What is actually needed is to remove the outer \left's ! Like this:
\documentclass{article}
\usepackage{amsmath,mathtools}
\begin{document}
\begin{equation}
y'(x)-\frac{y(x)^2+1}{(x+1)^{3/2} \left| y(x)+\sqrt{y(x)+1}\right| }
\end{equation}
\end{document}
There was no need at all the an extra () around, since the | | acts as a () any way.
@Nasser Find \left\left and replace it with \left or with \left(\left| same for right. But in general I don't like auto generated code of Mathematica or Matlab. It's 99% of the cases (whenever they are sophisticated enough) ugly. For example, I would separate the denominator and use 1/|...|
The question is pretty simple.

\documentclass{IEEEtran}
\usepackage{lipsum}

whereas compiling the same code with XeLaTeX gives me back
I'm curious why this happens, but more importantly, I'd like...
I know that this question may be not in the main stream, but it is the matter of communication.
We have LaTeX graphic packages graphics (s as standard) and graphicx (x as extended). I am thinking that the former should be pronunciated /ˈɡræfɪks/, but what about the latter?
@DavidCarlisle hey don't spoil the moment with your fault-proof logic. :)
Dear Ohloh user,
We would like you to be the first to know of an exciting update to Ohloh.net. This week, Ohloh will be changing its name to the Black Duck Open Hub.
You learn something new everyday... or so they say.
Thoughts on why bibtex entry keys are not case sensitive?
It seems like everything else in the TeX world is case sensitive, so I was surprised to discover a citation that worked, but seemed like it shouldn't (because of change in case)
@PauloCereda one done already:-) but I'm out of action as I'm moving stuff to new machine... (wow installed cygwin in under 15 minutes rather than half a day as previously... seems like an i7 and an ssd disk is faster than an i5 with an old disk that keeps blue screening with disk errors ...
Friends, a quick poll: grind lines in plots or not?! I just got feedback from a reviewer who said that one should never add gridlines, but IMHO they can add clarity. Opinions?
Another small question, after seeing tex.stackexchange.com/q/1930/21930. What's the real reason to use \begingroup. It seems that the only relevant “pro” is that is transparent in math mode. Isn't anything more behind them (versus the usual grouping { or \bgroup)? I'm disappointed :D I always thought it was more important.
@PauloCereda I think so too. Just trying to build some argumentation for the reviewer (allthough that's maybe not the best idea :-]). Unfortunately I don't have a copy of Tufte around, maybe there would be some points in there.
@Manuel well why pick on \begingroup you could ask about any primitive. \begingroup can be used in less places than \bgroup so the fact that you get an error in the other cases depends on your point of view, as to whether a program should silently tolerate users or if it should complain if they stray off the signed path
@egreg easy points and two badges (after a helpful edit I should add:-)
@PauloCereda not yet don't want to do too much until everything copied from old machime. I was going to just zip stuff up and copy it but was told to use the "microsoft transfer wizard" and that said it was going to take 2 hours so I went to a meeting came back and it says it's got 5 hours to go....
@PauloCereda Thing is once it's copied everything I'm going to delete most of it as new disk is ony 1/3 size of old one, but at least it's an excuse for not doing too much today:-)
@izabera I'm cleaning the repository, there was a lot of things in there, so I'm slowly updating things. But the old code is accessible from past commits.
@TamerKözleme Hi! You have arrived in the middle of a party! We're partying because our esteemed member @Werner reached 200K reputation! A very great achievement!
I wrote a book about LaTeX, and my proud grandma wanted to have a copy. So she got it, said "What a beautiful picture on the cover!" and - "What is this, LaTeX?".
She doesn't know Word, never used a computer. But she reads books. How can I explain what makes TeX and LaTeX special to a non-techni...
Yes, I changed the brevefill with the less heavy one and it's certainly better but still to thick. In any case, thanks a lot for the effort you put into this. Really. — Sabian2 mins ago
@DavidCarlisle I'm not sure I understand you (or you understood me). I was just asking… because my feelings was like \begingroup was more robust (not in the TeX way), like if \bgroup (which is {) was the poor-man's groups, and \begingroup was the high quality one. But it seems that except for that transparency in maths… there is no other reason to use \begingroup. I mean, every \begingroup in all the questions and answers this page could be just a \bgroup, or am I wrong?
What, if we dismiss the transparency in maths, was the reason or need for this kind of groups?
@Manuel well as I say you can usually replace \begingroup by \bgroup but not the other way round, so you can choose to use \bgroup or \begingroup depending on whether you want an error:
@Manuel in the above \bbb silently works, but \aaa is an error, so when making the definition you have a choice on what usage you want to accept (althouh hard to think of a pure latex example, I used the \hbox primitive here for a reason:-)
I'm confused as to why there are more command codes after the catcodes and some command codes are duplicated under different names. Why not separate out the builtin tokens
For example, comment, end_match, & stop (used by \end & \dump) all use 14. They seem different enough to warrant separation.
an evil mastermind kidnapped an infinite number of smurfs and caged them in a room.
he said them: "tomorrow i'll give each one of you a hat with a real number on it and i'll put you all in a line. you won't see the number on your hat, but you'll see all the numbers on the hats of the smurfs after you. if you guess your number correctly you'll be free, otherwise i'll kill you. muhahaha"
the smurfs are quite smart, and they found a strategy that will save as many lives as possible. what's this strategy?
@PauloCereda Well the stats are meaningless: they are only reliable for the 'SVN era', which means I come up very high. None of the early CVS/email commits count, nor of course does LaTeX2.09 (no idea what Leslie did version-wise)
> The source code for LaTeX might actually be older than the source control history can reveal. Many new projects begin by incorporating a large amount of source code from existing, older projects. You might be able to tell whether this is the case by looking for a rapid rise in the amount of code early in the project's history.
@PauloCereda the sysadmin amuses himself naming new machines and I guess he knew I knew about *ml things I didn't notice until just now (it's in the default cygwin bash promt:-)
@anderson I see quite a few edits over the past few minutes: nothing wrong with keeping things tidy, but remember that too many in a row will 'flood' the front page!
It is always someone's birthday. I would like to use TikZ to draw a birthday cake. There are all sorts of cakes. What I would like is a cake that looks nice and tasty. Preferably a cake with lots of chocolate and vanilla custard. How can I draw this with TikZ?
Here is something to start with:

@ChristianHupfer This actually only happened in other peoples' bee yards; not my own. Our bees are very calm, but other beekeepers may handle their bees with less care.
Either way, I only just started, and it's an iffy time of the year.
Lots of wasps around and the food sources are getting scarce.
So the bees are alert, and need to defend their territory.
@ChristianHupfer We were involved in some political activities around our municipality, which lead to a change in bylaws. The bylaws were specific to the keeping of domesticated animals on city-like lots.
This included the keeping of backyard chickens...
...and the change in bylaw added that home owners could keep bees.
We jumped on the opportunity, spent about 1 year preparing hive boxes and going crazy learning stuff...
...and got the bees this year.
And I've been stung three times. ;) It's all good!
@ChristianHupfer if people already have a »working« work flow it's hard... the only thing I know that works is the visual evidence that LaTeXed documents look better. But also then: some people just don't care...
@cgnieder: Yes, I understand that, but young colleagues, all physics and math teachers like me (ok, they have not done research etc. before) could learn LaTeX to provide better documents.
@cgnieder; Ok, not like me, I am not young anymore :D
