I've just finished Chapter 1, and I would say it is as good as the article. One caveat is that while the book claims it can be understood by a person who can't program, I'd expect them to feel rather mystified during the many coding parts. Even so, the surrounding text explains the code well enough it probably wouldn't impact a persons ability to understand the material being presented. It's not aimed at 5-year-olds but I'd say it's not aimed so much at the titles Engineers. One thing I've appreciated is the presentation of raw data. Every time a new type of data is introduced, the book shows its structure. It's been much easier to get what's going on as a result. Hope the rest is as good as the first chapter.
