Well, to be fair, one of the very first questions
I asked upon joining wikien-l was whether the
database and webserver were on one host or two,
with exactly that reasoning in mind. But I don't
think I've written any well-known books...
unless the Wikipedia itself counts? ;)
I believe Jimbo was talking about Ian Gilfillan, author of "Mastering
MySQL 4", who posted a couple of suggestions back in February.
