Good article but a little resarch into recent publications in systems conferences could have helped put it in a better direction. Althogh lot of programmers use text-book algorithm there exist a large body of work (in CS) that focus on the engineering aspects of algorithms. Look into compression/decompression algorithms like PPM for example and you will see O(n^2) algos are proposed as improvements over O(lg n). (run time vs. execution time). Design and analysis of algorithm is only one area in CS. Author is correct in pointing out CS programs lack engineering focus, at least in undergrad education.
