Someone asked, "Do you really need a persistent layer?"

I've never actually heard Mr Slackware before (i mean heard him speak), only heard about him since forever of course.

Of my heroes, i've seen some of them in real life. In order of appearance, Bill Joy, Eric Raymond, and Richard Stallman.

I've emailed a few heroes as well, a few years ago - and they even replied, a few times! Like Bjarne and Alex - the C++ guys. I'm not on first-name-terms with these guys - it's just that i can't remember and/or certainly can't spell their surnames right now!
