"you should have a great editor, technical writer"
Let's start by saying that if you plan to write and self-publish a book in English which is not your native tongue, you should have a great editor, technical writer, and probably a layout/graphic desinger person on your payroll. While some of the info is good, there are so many typos, mispellings, grammatical errors, misuse of common vernacular, and messed up page breaks, not to mention an overabundance of repetition within and between secrions, that reading the book is a bit of a chore. Use a highlighter and take a few notes and use those as your references and you should be fine. The technical info is pretty good. Plucking it out and keeping it relevant and making it useful is a chore. I bought it in part because it was cheap......
