This talk covers a general overview on the Unix operating system and
its inner workings: history, existing implementations (including
GNU/Linux and BSD), kernel and user land, the user model and super user
(root), the command line interface (shell) and its tools, the graphical
environment ("X"), the file system and its permission scheme, processes
and daemons, package management, etcetera.

If you are new to Unix/Linux or not an advanced user, or perhaps
even if you're new to free and open source software in general (of which
Unix is a big part today), this talk will certainly be of interest to
you.

This talk will be followed up by another talk by Sander Bos, which
will focus in more depth on the Unix command line interface and its
tools. Both talks can be visited independently, but visitors are of
course encouraged to attend both if interested.

The talk will essentially be in English, but might switch to Dutch
in case all attendees speak Dutch (this will be queried beforehand).
