@egreg: I recall @HeikoOberdiek writing something about \ooalign taking the width of the first/last element. Which is it? First or last?

egreg

@Werner The first sets the height, the second sets the depth. In this case it's irrelevant.

Werner

@egreg So the width is always just the widest element.

tohecz

@Werner yes

@egreg is it the second or the last that sets the depth?

egreg

@Werner Yes. It's customary using \hidewidth here, instead of \hss.

@tohecz The last, if you're bold enough to do \ooalign for three or more objects.

tohecz

@egreg :)

Hi @tohecz Tom! Nice to see your interest in my instant review bot (tm). It is based on Bilateral Teleoperation Systems. Sorry for the late answer ;)

@DavidCarlisle Ad "\hline problem get all kind of error". My answer in this thread was only an experiment about SE reactions. I put the stupid one-sequence answer to the simple question without explanation "why". I did it while somebody else was reformatting the question and somebody else was writing the comment about missing MWE :). The SE reaction was as I excepted: the stick plus votes were here in short time.

On the other hand, if I write some significant, for example my second answer in the "$$$...$$$" thread, nobody reacts.

@wipet Link?

@wipet I'd seen the second $$$ answer: I'd agree that the questioner is abusing align

A: \hline problem, get all kind of error

Only first \hline can be without preceeded \\. Next \hlines need to be written as \\ \hline. Edit: Sorry, my answer was only "LaTeX-like" answer to the LaTeX question. It means "do this and don't think about it". I try to improve this now. You can ask why there is the error message "Misplaced \n...

@DavidCarlisle Any idea why \includegraphics[width=.32\textwidth,height=.24\textwidth]{napeti2.jpg} gives Package graphics Error: Division by 0, but it does not when identical png picture is used?

Paulo Cereda

@tohecz A mathematician getting a division by zero error? tsc tsc. :P

Q: Any tips on our BEIJING CHINA tour?

There are several different parts of the Wall that are open to the public. These are Simatai, Badaling, and Mutieyu. Teach one offers something different - Simatai is the older, wilder, more broken down part of the wall, and you can get some fabulous hikes there without encountering many people. ...

@JosephWright Grazie. :)

@JosephWright I don't know how to put the link in this chat environment. Manual says that it is done by single line with URL, but I am unable to create the single line in my notice because Enter behaves as "Send" button.

Joseph Wright

@wipet You mean for example something like

A: Why in the discussion of the definition of \newif are the following things true

The Knuth's macro \newif is very cryptic. I spent full page 402 in my "TeXbook naruby" with explanation of this. But we can ask if there isn't more straightforward and more understandable solution of this task with equivalent result. I mean that it exists. For example: \def\newif#1{\expandafter\...

where the above is just the URL sent as a 'message'?

wipet

@JosephWright Bu I don't know how to do this :(

Joseph Wright

@wipet You need a post that is just the URL. So in the above I wrote (copied) http://tex.stackexchange.com/a/215303/73 into the chat box then pressed enter

@wipet You can't do the same as part of a mult-line message, which is why I had to post first part of a sentence, then the link, then the rest of the sentence

@wipet As I've said in my comment, my reading of that question is that it's explicitly asking for a 'trace' of the code Knuth uses, so while I see your point about an alternative to me that would be a separate linked question.

egreg

@tohecz Probably the JPEG advertises bad data about its bounding box or resolution

tohecz

@egreg oh well, that's possible, I probably forgot to +repage

wipet

10:34

@JosephWright I disagree.

@JosephWright Thank you for your detail explanation. It means that my continuous message can be interleaved by messages of another chat users...

Joseph Wright

@wipet Yes

@wipet That is of course your perogative

Paulo Cereda

Ignorance is definitely bliss. I have no idea of what you guys are talking about. :) It's all Greek to me. :)

One day... maybe one day... I'll be able to finish the TeXbook. Maybe. :)

A "spot the problem" game (one for @egreg):

perfect fluid in permanent rotation:
$\ln |u_t| - \ln |u_{t_{\rm in}}| +\int_0^{P_{\rm g}} w^{-1}\,dP-\int_0^l (1-\Omega l)^{-1}\Omega\, dl+\int_0^{\tilde{P}_{\rm m}}\tilde{w}^{-1}\,d\tilde{P}= 0, \label{AP3}$
where $u_t$ is the covariant component of the four-velocity (subscript `in'

Master of puppets, I'm pulling your strings!

cgnieder

@PauloCereda lol

egreg

@tohecz Do you mean the \rm or \label? Or the wrongly placed comma?

tohecz

@egreg well, \rm is a fate. The \label is just ridiculous. And which comma do you mean -- the one at the end?

Manuel

Do backticks in a title matter in any way? (about this recent edit tex.stackexchange.com/posts/215029/revisions)

tohecz

@Manuel this sounds like a reasonable reason. It's a well-known bug of SE

Manuel

@tohecz I don't follow. What's the bug? What sounds like a reasonable reason?

tohecz

@Manuel if you remove the backticks, the question title is very misformated in the Hot Questions on all sites on which MathJaX is on.

Manuel

@tohecz Got it. Okey. Understood

tohecz

@Manuel it's stupid.

Manuel

11:39

@tohecz Well, I just happened to learn about it :)

tohecz

@Manuel it's a marginal thing that doesn't happen a lot.

Joseph Wright

@tohecz Hmm, not that keen but I guess we have to be friendly to the rest of the network

tohecz

@JosephWright I'm not keen at all. It's ridiculous! And basically it's an XY problem, but sort-of the other way around.

@egreg one more:

\begin{eqnarray}
Q_{TB}=Q_{TE}
\end{eqnarray}
\begin{eqnarray}
\begin{split}&Q_{CHH}+Q_{HPA}+Q_{HPF}+Q_{EXN}=
\\&=Q_{HW}+Q_{UH}+Q_{FL}+Q_{OFG}+Q_{FHL}
\end{split}
\end{eqnarray}

you gotta love the warning:

Package amsmath Warning: Cannot use `split' here;
(amsmath)                trying to recover with `aligned' on input line 96.

egreg

11:55

@tohecz Yes, it should be outside.

@tohecz Beautiful!

tohecz

@egreg you especially gotta love notation $c_{GAS}$, which makes all four letters look like in one line.

egreg

@tohecz ^{} all around

tohecz

@egreg well, $c_{\text{\normalfont\scshape GAS}} is what I consider

but actually, I'll leave it be. Not my problem

damn this article

\begin{itemize}
\item useful heat $Q_{}$ -- the heat that is needed for heating a batch (endothermic reactions, etc.);
\item heat losses $Q_{}$ -- consisting of heat loss:
\begin{itemize}
\item o	through the furnace openings (doors),
\item o	accumulated in the lining,
\item by radiation through the openings,
\item cooling water,

(there are actually four spaces after \item o, prbably they wanted another nested itemize but it didn't quite work well as the first thing in the 2nd itemize?

egreg

@tohecz I wouldn't.

tohecz

@egreg well, as I say, I leave it be
