% talk about the difference between a desktop environment and a window manager:
% a desktop environment (like GNOME, KDE, Xfce) is a collection of
% programs, libraries (including a graphical toolkit) and configuration.
% it usually aims for a coherent look and feel and comes with a number of
% tools (g*, like gedit, geeqie, …)
% One of the programs of a DE is a window manager.

% compare this to a screenshot of i3:
% notice the little amount of toolbars.
% notice the lack of fancy window decorations
% notice the absence of a desktop.
% instead, you get to use the full screen.

\item Urgency hint
\item Scratchpad
\item Web development (browser, editor, syslog)
\item Coding (C): two editors (code, test), quickly opening docs

\mslide{i3 in numbers}{
\item 3149 commits by 39 different people
\item > 600 tickets (about 60 open)
\item about 10.000 SLOC (mostly C, a bit of Perl)
\item testsuite: > 1000 test instructions in 96 files
\item conservative guess of > 1000 users
