After years being more a manager than an academic I am slowly returning
to things I once liked to do at work. So now I am spending time in
making slides in LaTeX (I use the "slides" environment for 20 year and
have no plans to "upgrade" to something like the Beamer) and spent
several days in playing with the Gnuplot and the gcc and the
wish/tclsh.
This is much better way to spent the time than with the *Office...
