Lulu.com, the site David Wendt used to publish the book, has been really slow for the last few days, so if you want to buy it then using a direct link will be (slightly) faster:

Print version: http://www.lulu.com/content/168302
E-book version: http://www.lulu.com/content/168212

Or you could just wait until 1 a.m. and then place your order.

[On a side note, Newsforge posted a l-o-o-ong interview with Bob Young, Lulu founder and CEO, yesterday. You know... the Red Hat guy.: http://business.newsforge.com/business/05/11/01/15 34231.shtml?tid=3]
