And don't do live demos on your laptop where you might have personal
data unless you've already rehearsed every step of your demo in the
privacy of your own cubicle, and verified that nothing of questionable
interest might be exposed.

And on a completely unrelated topic, keep in mind that the resource
fork of a movie you downloaded to a UFS partition on MacOSX will be
stored in a file named "._moviename.mpg", which doesn't get removed
when you say "rm *".
