I am *careful*. I run as a regular user, not root. I alias rm and mv to 'rm -i' and 'mv -i'.
And I'm using Ubuntu, which doesn't even *allow* you to log in as root, for fear you might break something. You'd think. They might ask. Before deleting the whole fucking copy of a partition that I just set down for a few minutes while I moved things around and... rebooted, because I needed to put the physical drive in a different machine for a moment.
I hope they all die. Painfully. Alone.
