bibtex: Not writing to <project-path>/src.blg (openout_any = p).

I couldn't open file name `<project-path>/src.blg'

To get rid of the error, open texmf.cnf, which resides in /usr/share/texlive/texmf/web2c through
sudo gedit /usr/share/texlive/texmf/web2c/texmf.cnf
Then find the entry

openout_any = p

p is the paranoid setting. I changed it to r and it now works again (chapeau to dmj).

[update 31 Jan 2013] If sudo is not an option and thus texmf.cnf can’t be changed, see Sini’s helpful comment below. [/update]

If you want to learn about multiple bibliographies using multibib, there is a very good tutorial by peisistratos. Unfortunately it is in German, but I’m sure there are English ones out there, too.

Strikethough in LaTeX using »ulem«

\usepackage{ulem} in the preamble gives you two ways to strike out text (and a couple more for underlining):

1. \sout{text to be striked out} for a horizontal line through text to be striked out (exactly like »line through«).
2. \xout{text to be crossed out} for many short diagonal lines crossing out the letters of the text to be crossed out

The problem that ulem affects some bibliography styles where otherwise italicised text is then underlined can be remedied through the »normalem«-option in the preamble: \usepackage[normalem]{ulem} (Thanks Fredrik!).

Ulem is part of MiKTeX and TeX Live but also available at ctan.

Strikethrough in LaTeX using »cancel«

\usepackage{cancel} in the preamble gives you four different modes of striking through

1. \cancel{text to cancel} draws a diagonal line (slash) through its argument
2. \bcancel{text to cancel} uses the negative slope (a backslash)
3. \xcancel{text to cancel} draws an X (actually \cancel plus \bcancel)
4. \cancelto{〈value〉}{〈expression〉} draws a diagonal arrow through the 〈expression〉pointing to the 〈value〉 (math-mode only)

You can get cancel at ctan.

Cancelto also works with more complicated expressions:

I wanted to have footnotes from inside sections, subsections, and subsubsections. They work similar to footnotes in tables, you need to address them similar to this:

\section{Some Section in my Document\footnotemark}

\footnotetext{My boring footnotetext.}

Only, when I did it like this, it worked on some occasions, but not on others (reason for me biting the wood).

I finally found out that it did not work on all occasions where I did it exactly like in above example, but always rendered

TeX capacity exceeded, sorry [input stack size=5000]
However, it did work on all the occasions where I specified the (optional) short title for section/subsection/&c:

\section[Section in Document]{Some Section in my Document\footnotemark}

\footnotetext{My boring footnotetext.}

The optional shorter title appears — as far as I know — in the table of contents and in left-/rightmark. Also, Kile uses it to display the document structure, too. So if you have rather long titles (like I do) it is a good idea specifying a short one anyway. If not, I guess you can just as well repeat the full title in the optional argument if you need a footnote.

When using the starred variant (\section*{My merry section}), don’t provide a short title.
