rectangular emacs

Just now had the occasion to use the rectangular select/cut /paste

C-x r * where * is k for kill , y for yank(paste)

cross-compiler hell

cross-compiler are a pain in the ass .

kegel.com/crosstool is helpful in such cases

anyway if you ever build powerpc-eabi cross compiler and you get the error

powerpc-eabi-gcc hello.c -static
hello.c:(.text+0x24): undefined reference to `printf'
/opt/ppcsim/lib/gcc-lib/powerpc-eabi/3.2.1/libgcc.a(eabi.o): In function `__eabi':

use the -msim switch when compiling

dont ask me the logic behind it ..but I got it from
http://sources.redhat.com/ml/crossgcc/2002-09/msg00096.html
and it worked for me.

wrapped text in tables

use package tabulary for wrapped text in tables

\caption{capshon}
\begin{tabulary}{\textwidth}{lL}...
\hline
\hline
A & B \\hline
A & bbbbbbbbbbbbbbbbbbb\ X & ccccccccccccccccccccc\
\hline
\end{tabulary}...
\label{label}
\end{table}


--
for some odd reason, the label has to be where it is, when i triedto move it up below the caption i ended up with more than 100 errors

\texorpdfstring{LATEX text}{PDF text}



can be used to vary the text, depending on whether it is to be processed by LATEX or whether it will appear in the PDF bookmark. The above section heading could then be changed to

\subsubsection{An Example Heading\texorpdfstring{: $a^2+b^2=c^2$}{}}

In this case, the equation will be printed in the section heading within the document, but will not appear in the bookmark.

Reset $. at EOF

When using perl $. variables, you may need to reset $. for each new file.
