Error message of biber 1.8 (TL 2014-pretest):
data source /tmp/par-6f6e65/cache-109396a1c504bff74518ed78dd32b123e9ef7c31//inc/lib/Biber/LaTeX/recode_data.xml not found in .
Any idea, what to do with this crap?

@GonzaloMedina Oh, anything that looks fancy...

...something that is similar to what people would post say "please do this for me" that they scanned from a book. :)

Found, when writing a ghostscript bug report: File size limit ≈ 48.8 GB.

@GonzaloMedina I've found this:

Q: How can I reproduce this beautiful table of contents?

I stumbled upon this TOC today: I really like its structure and simplicity. The page numbers are right behind the entries, and not unnecessarily remote as they often are. The separation between chapter numbering on the left and titles on the right clearly sets the two apart. I would like to r...

table-of-contents

I'm now looking for a nice minitoc representation that might match this.

@GonzaloMedina Are you around? I have a question about your forest question.

Heiko Oberdiek

Sorry for the noise with biber, I found the solution: tex.stackexchange.com/a/140815/16967 Thanks @AlanMunn

Alan Munn

@HeikoOberdiek You're welcome! I'm surprised you've not encountered that error before. :)

Heiko Oberdiek

@AlanMunn After running into so many new errors (pdfTeX, ghostscript, ...) I was indeed surprised running into a well known one. ;-)

Gonzalo Medina

3:28 AM

@AlanMunn are you still around?

Alan Munn

@GonzaloMedina Yes. Did my solution help you?

Gonzalo Medina

@AlanMunn Partially yes.

Let me show you the real situation.

\documentclass{article}
\usepackage{forest}
\usetikzlibrary[calc]

\newcommand{\ninepuzzle}[1]{%
\begin{tikzpicture}
    \foreach [count=\i] \val in {#1} {
        \draw  let \n{row}={int(mod(\i -1, 3))}, \n{col}={ int( ( \i - 1 ) / (-3) ) } in
            (\n{row}, \n{col}) rectangle  +(1,1)
            +(0.5, 0.5) node{\val};
    }
\end{tikzpicture}%
}

\begin{document}

\ninepuzzle{1,2, ,3,4,5,6,7,8}

\begin{forest}
[\ninepuzzle{1,2, ,3,4,5,6,7,8}
  [\ninepuzzle{1,2, ,3,4,5,6,7,8}
  ]
  [\ninepuzzle{1,2, ,3,4,5,6,7,8}

\ninepuzzle draws a 3x3 grid with numbers inside. Using it directly in forest, the grid appears but not the numbers.

Alan Munn

@GonzaloMedina So is it not possible to adapt the \foreach code into the tikz= key?

Gonzalo Medina

@AlanMunn I Perhaps it is. I did one attempt but failed; perhaps I'm too tired already.

Alan Munn

@GonzaloMedina I'll mess around and see if I get anywhere.

Gonzalo Medina

3:43 AM

@AlanMunn OK. I used the same comma separated list as the argument for \ninepuzzle in the code above, but the list might vary (always nine elements in the list, but the order might be different).

Your approach looks promising.

Alan Munn

@GonzaloMedina This is on the right track:

\begin{forest}
ninepuzzle/.style={tikz={\foreach [count=\i] \val in {#1} {
        \draw  let \n{row}={int(mod(\i -1, 3))}, \n{col}={ int( ( \i - 1 ) / (-3) ) } in
            (\n{row}, \n{col}) rectangle  +(1,1)
            +(0.5, 0.5) node{\val};
    }}}
[,ninepuzzle={1,2, ,3,4,5,6,7,8}
  [,ninepuzzle={1,2, ,3,4,5,6,7,8}
  ]
  [,ninepuzzle={1,2, ,3,4,5,6,7,8}
  ]
]
\end{forest}

But the nodes are drawn on top of each other.

Gonzalo Medina

@AlanMunn Yes, but you're right; it seems to be on the right direction.

Alan Munn

@GonzaloMedina The problem with the nodes is that your code has absolute coordinates, and they need to be relative somehow (when incorporated in the tikz= key).

Gonzalo Medina

@AlanMunn Yes. Tomorrow I'll play a little more with this. Now it's time to go to bed; I am exhausted! Good night, Alan and thanks for your help.

Alan Munn

You're welcome. I'll also play around and see if I have an answer.

Hello,

could anybody tell me what the community thinks about the following type of advertising?

I'm currently writing my bachelors thesis about symbol recognition. Symbol recognition systems need example input (the more, the better the classification gets).
So I would like to post links on this page where it is apropriate (e.g. http://tex.stackexchange.com/q/179554/5645 or http://tex.stackexchange.com/questions/9363/how-does-one-insert-a-backslash-or-a-tilde-into-latex/9365#comment413643_9365 ) to http://write-math.com.

@moose I don't know how exactly the community ad thingy works (@JosephWright), but personally I wouldn't mind seeing a pointer to a TeX-related empirical study there.

@JosephWright SPAM time again.
