TeX, LaTeX and Friends

12:34 AM

@werner Hi my friend... Your example is not good... I upvote the @DavidCarlisle's second comment ;)

@SeanAllred It has been dealt with already at meta and its aftermath came good reviewing practice which I hope @Papiro might be following :)

Papiro

@texenthusiast ;)

texenthusiast

@Werner In my view,that's fine along as someone's enthusiasm helps to share the work load with some good reviewing practice,even though it might be for a short duration/months/interest in badges etc..

Papiro

BTW, my dear friend @Werner have 1171 reviews in "Close Votes" and do not "quit" yet..

texenthusiast

@Papiro On a postive note, I thank you for your eager interest here as we are all also, share the load to get a good quality reviews, as each question genre is different and the diversity of questions requires expertise stretching land to sky and we have many experts in the same range.

Papiro

@texenthusiast you are right.

Sean Allred

Yes, @Papiro, you have done no small service to TeX.SX at large :) Although, I'm not sure if upvoting a comment should be considered review… but if the behavior exists, it is more than likely that SE put it there. (I realize I might have been a little terse with my first message, so I apologize. :)

Papiro

@SeanAllred no pro :)

@Papiro I just envy your reviewing ability, and I honestly have no idea how you always seem to be one step ahead.

In the past we've discussed whether it has something to do with your browser - it seems like you're always at the right place, at the right time.

@Papiro: Don't take my discussion the wrong way. As I've said in the past, it's just bizarre.

Papiro

1:52 AM

@Werner no offense, sorry. As I have said in the past too, I have a lot of time, a very good Internet connection, and all my days is in front of many computers. I am not a LaTeX expert as you but I am trying to do my best. I am not just "removing thanks" anymore :-)

Werner

@Papiro Ha ha! Good work!

Papiro

@Werner He he! Thanks!

Just discovered that TeXworks now supports bold/italic/underline in syntax highlighting

Don't think I'll use it, but worth knowing

@karlkoeller Thanks for interest in my TeXworks .dtx stuff

The WinEdt .dtx mode is really very good and was perhaps the one think I was reluctant to switch from when I decided to go with TeXworks

(I never really used much of the rest of the power of WinEdt)

Andrew Stacey

@JosephWright Oh, you deleted your comment as I was replying.

hhh

I want create a large visual matrix with only A written in the middle of the block, how would you do it?

I want to specify its width and height

Joseph Wright

@AndrewStacey Sorry: I reread the text and worked it out

Andrew Stacey

@JosephWright I've deleted mine now as well since otherwise it looks odd.

Joseph Wright

@AndrewStacey Not being an Emacs user I didn't know what 'specials' were in the context

Andrew Stacey

6:51 AM

@JosephWright Oh, and thanks for the heads-up on the "definitive list".

Joseph Wright

For me, specials = \pdfliteral, _etc. :-)

@AndrewStacey No problem

Andrew Stacey

@JosephWright Being merely a "Cargo-Cult Emacs User", I don't know either. I just copied stuff from the latex font-locking until it worked.

@JosephWright I always try to add new features in WinEdt when I can, since it is my favourite editor. As you can see I've already started

A: LaTeX3-sensitive editors

OK. I've started making modifications to WinEdt's configuration files to include expl3 syntax highlighting and probably these changes will be included in the next release of WinEdt. As such, this answer is a work in progress... You can include these modifications as soon as I add them in the ans...

hhh

I am trying to do this kind of matrix, how would you do it?

(a block A surrounded by zeros on the right and on the bottom and one in the corner)

Qrrbrbirlbel

@hhh Easily doable with TikZ, you can also do this with arrays. There are surely some examples on the site …

hhh

3

A: Exact height of \hbox

Do not use the Tex primatives \vbox and \hbox in directly in latex, because they are not color "save". Use the latex equavalents \parbox, \makebox, and minipage. The code below gives you a ruled box with required outer dimension (including the rule width and separation) EDIT: Rather use t...

(I know how to do squares but not how rectangles or make rectagles with that kind of zero line. Or do I need to create many squares?)

Qrrbrbirlbel

7:35 AM

@hhh Without TikZ:

\documentclass{article}
\usepackage{amsmath}
\begin{document}
\[
 A_\mathrm{new} =
 \left(\begin{array}{@{}|*5c|c@{}}
   \cline{1-5}
   & & & & & 0\\
   & & & & & 0\\
   & & A & & & \vdots\\
   & & & & & 0 \\
   & & & & & 0 \\ \cline{1-5}
   \multicolumn{1}{c}{0} & 0 & \ldots & 0 & \multicolumn{1}{c}{0} & 1 \\
 \end{array}\right)
\]
\end{document}

hhh

That is very cool, I had very very ugly...(getting now removed...)

\setlength\unitlength{1ex}
$\left(
\begin{picture}(18,8)
\put(0, 2){\mybox[c]{red}{12}{A}}
\put(12,2){\mybox[c]{yellow}{2}{0}}
\put(12,4){\mybox[c]{yellow}{2}{0}}
\put(12,6){\mybox[c]{yellow}{2}{...}}
\put(12,8){\mybox[c]{yellow}{2}{1}}
\put(0, -6){\mybox[c]{yellow}{4}{0}}
\put(4, -6){\mybox[c]{yellow}{4}{...}}
\put(8, -6){\mybox[c]{yellow}{4}{0}}
\put(12, -6){\mybox[c]{yellow}{4}{1}}
\end{picture}
\right)$

percusse

@Werner Maybe he is parsing the RSS feed... :-)

for 1 and 101 points heheh

hhh

8:06 AM

$\mathbf{c}_\mathrm{new}=\left(\begin{array}\bf{c} & \alpha_{n!+1} \\ \end{array} \right)$

What is the problem with this?

Qrrbrbirlbel

@hhh You are missing the first argument of array, the column specifications.

hhh

For some reason, the $\bf{c}$ inside or even $\mathbf{c}$ does not work there.

(not getting bolded)

Qrrbrbirlbel

@hhh But the image shows {c}, but the code has a & indicating two columns.

Should work with \begin{array}{cc}.

percusse

@hhh Forget about \bf never use it. Also \bf{c} is not correct it doesn't accept arguments. Either '\textbf{...}` for the argument or \bfseries .... for the switch. \mathbf{...} inside the math mode.

hhh

Hoops...$\mathbf{c}_\mathrm{new}=\left(\begin{array}{c}\bf{c} \\ \alpha_{n!+1} \\ \end{array} \right)$, now it works. @Qrrbrbirlbel thanks.

err \mathbf instead of \bf

Thank you, missed the & when it should have been \\.

Qrrbrbirlbel

8:13 AM

@JosephWright Are you going through unanswered questions? So many notifications … ;)

@JosephWright What is the new "too localized", anyway? Or what is the correct close reason for old packages etc?

Joseph Wright

@Qrrbrbirlbel Yes

@Qrrbrbirlbel TL got removed: we now are supposed to say something like 'off topic because we don't answer about ...'. I'm using unclear instead, though :-)

Papiro

8:44 AM

Hi @percusse ! Hehehe I am using the RSS feed as an input to a very sophisticated Neural Net to generate a Kohonen Map. Then, I use this map with my homemade unpublished cryptographic algorithm FNF (Fast Ninja Finger). Done! All my secrets uncovered :-)

percusse

@Papiro That was a joke. But, while I also envy your enthusiasm, you need to pay attention a little to what we are trying to signal to you.

You are using a very generic boilerplate comment which sometimes looks awkward.

And that is not always welcome by the newcomers

Papiro

@percuse ?? Do you have a example?

percusse

Put another secret script that it changes those comments to something more humane once in a while.

Example; any given fast pasted auto-comment of yours.

Not everybody likes to be welcomed with a review bot.

Even though you have pasted them, it looks like a bot because of your speed

Papiro

hehehe "Welcome to TeX.SX!" is offensive?

percusse

sometimes yes

because you have a link

and this has been discussed a lot in Meta

Q: Welcome page needs more welcoming

We try to welcome all new users to the site by giving them a "Welcome to TeX.sx!" link in the comments of their first question or answer. But I've seen a few recently (here's one) where users comment back: "I'm sorry, did I do something wrong?" Then the original welcomer has to say, "No, really,...
