Murphy's Laws on Computers

As soon as you delete a worthless file, you'll need it.

Installing a new program will always mess up at least one old one.

You can't win them all, but you sure can lose them all.

The likelihood of a hard disk crash is in direct proportion to the value of the material that hasn't been backed up.

There are only two kinds of computer users: Those whose hard disks have crashed, and those whose hard disks haven't crashed - yet.

Anything can be made to work if you fiddle with it. If you fiddle with something long enough, you'll break it.
