run parts
Can we rename this to something more friendly? I had a problem that could have been resolved had I known about run parts. Instead, I had to resort to this forum (http://askubuntu.com/questions/8426/cron-hourly-wont-run). If we rename it to something like "external scripts" or something with a proper effect, it may be more helpful.

cron x.org aplications
In wiki you said
17 02 * ... env DISPLAY=:0 /usr/bin/xclock
(maybe a advice that xclock is not installed by default may help) This line do not work in modern instalations, because it need authorization. there two diferent ways to do: When your user start their graphic desktop run (you can put it in autostart scripts)
echo `xauth info | awk -F"Authority file:" '{print $2}' | tr -d ' ' | head -1 ` > ~/.xauth
then when you running programed apps this will use authentication for x.org
17 02 * .. export DISPLAY=:0; export XAUTHORITY=`cat ~/.xauth` ; /usr/bin/xclock
Other way to do "same" if your user it's the only user with graphical interficie:
17 02 * .. export DISPLAY=:0 ; export XAUTHORITY=$(ls /tmp/xauth* 2>/dev/null | head -n 1) ; /usr/bin/xclock
I'm not a good english writer, so if some one can write this idea well and put in wiki will help
