content: i needed some comments on the linux ip code, the title was right and there was a five stars review by a reader, had no time to wait and so i ordered it by e-commerce. Already accustomed to comments a la R.Stevens was very hopeful What a mistake ! more than 450 pages of linux kernel listings, not only, the listed kernel was 2.0 (at this time the firsts 2.4 are out) !!!! The commentary, all at the end of the listing not very insightful, will never buy another book in this series !
