Ada, a dead language that will get you a dead end job is shown in all it's splendor here. After reading the second chapter you're supposed to be able to write your own business and scientific applications. Yeah right! This book isn't just the worst programming book I've ever seen, but also the worst book I EVER read.If you REALLY want to learn Ada, use ADA 95: Problem Solving and Program Design by Koffman and Feldman. It teaches you at least.
