I thought that screen doors were meant for keeping out insects. In
computer terms, that would be unwanted visitors who just happen by,
not those determined to enter.

At home, I leave the door wide open and only the screen door protects
us. The insects stay out. However, we do not have the petty crime
problems that I am aware that some areas have. The Internet _does_
have a petty crime problem, I know.

I do not think that they can crack root without my 8 character
upper/lower/number password. Can they? How would having my own account
As for the backup situation, it is excellent. I back up /home to an
encrypted tar file once a month, and put it on a separate drive on the
same computer. My laptop backups go there as well. Occasionally, I
copy recent tar backups to a spare hard drive that I leave at the
mother in law's. I am fanatical about backups, and test them about
twice a year (when I reinstall the OS).

Again, how would having my own account, as opposed to sshing as the wife, help?

I simply fail to see the benefit.
A: Because it messes up the order in which people normally read text.
