Query: Richard succeeded

Being a good reviewer, doesn't mean automatically being a good writer. On the contrary, is so easy criticize and so hard write good books. . .However against the odds I must admit Richard succeeded in this new role, and wrote a very good book. Perhaps a bit overcharged of dumps. . . but useful and representative ones.Tired of too much theory and so little practice?. . . then just buy this book and hands at work.I got dozens of security books (I do my living as security specialist) and am every time more careful when buying or recommending books. This one deserves to be in every specialist shelf.
