* while we're on the copious debugging information track, try ltrace(1) sometime. it shows all library calls made (consider how often you call strcmp, then ponder how much information this is going to churn out :)
* procinfo(8) gives a nice summary of the kernel information available in the /proc filesystem, such as memory/CPU usage, kernel modules, [IRQ] usage, devices and supported filesystems. See ProcFileSystem
-* netstat(8) shows active connections, including tcp(7), udp(7) and unix(7) socket connections. "
netstat -anAinet"
shows all IP ports that are open on your machine - very handy.

-* depending
on the permissions on certain executables, you can start another X server as a normal user. (default
Slackware lets you, Debian
doesn't). To use virtual terminal 8 (which is normally unused), do "
xinit /usr/bin/X11/xterm -display :1.0 -- /usr/bin/X11/Xwrapper :1.0 vt08"
. Now if you run X programs with display
set to :1 instead of :, they go to the server running on vt 8. see
xinit(1), Xwrapper(1)

-* learn latex(1)
for documentation,
or if you're lazy, use lyx(1
) instead
. You can use pdflatex (which is normally included with the "
tetex"
package that provides latex
for linux distributions) to create PDF files in any style that normal latex
allows you to. This is very handy for making portable slide presentations as well as the "more typical" reports and articles.

-* For pure eye-candy
, your desktop's "background picture" doesn't have to be a picture at all. You can amaze [Windows] users by running one of the xscreensavers
in the root window. I personally like atlantis ; if it's not in /usr/bin, it's probably in /usr/lib/xscreensaver. Start it by%%%
__$ /usr/lib/xscreensaver/
atlantis -root &__%%% If
you have hardware accelerated [OpenGL] graphics, it takes
negligible CPU usage
. If
you don't know where it is, you can try __locate atlantis__ ;
