Query: Yuck

I HAD to buy this book for a college course. If you want to know the basics about each and every flavor since Windows 95, you'll like this book. But his Linux knowledge is severely limited, and his knowledge of other Unix variants is even worse. Palmer & Waters have not used a unix machine in their lives and as a Unix admin I was quite disgusted with the ludicrous tripe they present, and I can assure you that much of it was wrong. While we get page after endless page on Microsoft domains, NIS, NIS+, and LDAP are entirely missing. The structure of each chapter is: 15 pages on W9x, WNT, WMe, W2K, WXP, W03, 3 paragraphs on Linux, 3 paragraphs on "Unix" which the category he uses to cover all non-linux variants, and 3 paragraphs on Macintosh.To the authors: before you write a book on operating systems, get familiar with them. I could do better than you.I would have given this book zero stars if it was possible.
