This book provides an overview of the uses of 3D printing and the potential it has to become prominent. It also covers technical aspects of building a 3D printer and the software that is needed. A discussion of past and present devices is provided. I was originally interested in learning about how to best use my printer but became interested in all the varied systems and there capabilities. I was not interested in making my own system from scratch. So that section was not valuable to me other than that I might need to repair my system some time in the future. I liked this book and recommend it to anyone interested in 3D printing.… (más)

For perspective, others reading this review to make decisions may want to know I have a fairly decent and fairly wide background in IT, including systems and network administration, but I am mostly a computer programmer, so the Security+ information area is not where I spend most of my duty time.

When a recent job change required me to get a Security+ certification, I felt it would be easy to do, but that i needed some study material that covered the certification objectives.

This is the book I used to study for the Security+ certification. The material is pretty well organized by exam objectives, which I found useful for judging my own progress. I felt the "check on learning" questions at the end of each section were vague and the multiple choice answers were ambiguous, so in that sense I felt they were poorly worded, but the authors were explicit that these questions were "scenarios" and such, not exam question pool items. The pre-section questions were of no use to me.

The book includes 2 sample exams, but as this is a multiple choice test, one can only use an exam one time to assess mastery, after that you are remembering the multiple choice answer, not the material the question supposedly covers.

I supplemented this book with the exam cram questions book. It is also not certification exam question pool items and makes no claim to be so. Folks who can read the book and learn the information that way, could skip the exam question book, I don't feel it added much to my successful completion of certification.

I successfully passed the exam, and I feel studying from this book got me 70% of the way there. I did have to supplement with another study source. my final score was well above passing, though not a perfect score by any means.

Overall, a useful method for studying this material, and it got the job done. It was not easy reading. Later chapters seemed to be less well edited, but if one can overlook grammar issues and such when studying technical information, it was not a problem.… (más)
