Back up slides in Latex

 To have back slides in latex and not screw up the slide numbering, do this.
 1. Add these after your \usepackage{} lines, before \begin{document}
  \newcounter{sauvegardeenumi}
  \newcommand{\asuivre}{\setcounter{sauvegardeenumi}{\theenumi}}
  \newcommand{\suite}{\setcounter{enumi}{\thesauvegardeenumi}} 

2. Then, as below.
\begin{frame}

Your last slide...

\end{frame}
% BACK UP SLIDES
\newcounter{finalframe}
\setcounter{finalframe}{\value{framenumber}}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{frame}
.
.
.
\end{frame}

\begin{frame}
.
.
.
\end{frame}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\setcounter{framenumber}{\value{finalframe}}
\end{document}

Setting up website on server at IITB

Paste all your files in the public_html folder.

if you can't do that. run
~$ ls -l
and see if have ownership rights on the folder. If you dont, send a email to admin[at]ee[dot]iitb[dot]ac[dot]in and ask them to give you those permissions.

Once you can copy into the folder, you are almost done.
go to - http://www.ee.iitb.ac.in/student/~loginname/

If your CSS file is not loading, then ssh to your account from a terminal, then run
~$ chmod -R 755 public_html

(the -R is very important)

Should be all working now.

Peace.
