Too basic to be helpful.

I wouldn't even call it a primer...because even primers add to someone's knowledge. This book did not. No insight, no tips, no special information that isn't already plastered all over the web and found within a 60 second search.

As other reviewers have said, the book is extremely basic. It assumes you know how to play, but want some tips that will help you beat your friends or family members. Unfortunately, this book isn't going to help you very much. It is only 56 pages long, and each page is short. The bulk of the book discusses "8 Principles" that the author says will improve your play. Principle #4, for instance, is "Castle Early, Castle Often." You are told how to castle, and advised to be sure to do it so your king will be safe. That's about it. Principle #5 is "Keep Your Queen Back." The author tells you why it is risky to move your queen too early, and then relates an anecdote about a kid who didn't get better at chess until he learned to follow this principle. That's it. No examples. No diagrams of a chess position that shows a queen in danger because it moved to early. The entire book has only about a dozen examples of moves or positions. The paperback is currently selling for $8.97. I can't imagine paying that much for such skimpy information. The kindle version is now priced at $2.99. If you don't mind paying that for a half hour read, I guess you could learn something useful, but don't expect too much.

It isn't really all you need to know about designing. Very few and light information. Non practical either useful.

This was a pretty basic book.  If you're new to Linux and maybe even operating systems in general, then this book might be helpful.  I sent it off to the local donation center.

This book is really nothing more than a guide. If you don't have time to search the internet (and the stuff is not hard to find) then this book may be of some help. It's amazing how they managed to fill up so many pages and  tell you very little. They tell you about all of the tools and where to get  them, but they give you nothing on how to use them, with the exception of  nmap and ncat. If you can get this book used for a few bucks, then it may  be a good buy as a reference, but don't buy it at the retail price.

This book tries too hard to cover too many topics and ends up providing relatively basic information on a wide variety of things, without being able to go deep in any. It is targeted towards a networking novice, so introduces some very basic concepts. While there is some focus on Cisco products, most of the information is outdated and too high level to be meaningful (you can get more current / detailed information on the Internet). It would have been more useful to stick to a few core subjects around routing/switching, and explore more in-depth what specific Cisco products can do, and how to use them effectively.

Definitely designed for children or simple-minded adults. Not very helpful.

Very rudimentary, truly a wast of time and resources spent on this. Possibly for the absolute beginner it might be helpful.

I took a basic class and didn't really learn anything new. Its common sense in most of the techniques like cut and paste charts or worksheets into word or Powerpoint or email.... its only helpful to beginners. Its doesnt really explain the pivot tables too much or formulas and functions either. its basic stuff. I had to buy other excel books.

This was a free book, but it was so "duh!" to me that I didn't find it helpful at all. I suppose it's a great book for cavemen or those who have NO common sense and realize it's nice to say "please, thank you". I do think our society is forgetting manners more and more but this book doesn't really offer advice or any helpful tools. It goes over all the manners we should teach our kids and that WE ROLE MODEL these to teach. That's it...there's no other helpful advice to teach them other than to role model.

This is just another tutorial. It doesn't worth the money you pay for it.

The book represents only a very basic level of the subject; and it does not do it very well.  There is much more to segmented turning than is presented here.  If you are just starting and have plenty of money, buy it.

I am a complete and utter novice at programming.  This book helped me learn the basic nuts and bolts of programming.  But this book needs a chapter on how to put the pieces together to solve various problems.  I tried the exercises at the end of the book and was completely lost.  I wasn't even close  to the right answer (well, maybe two lines were right).  I tried everything.  I even looked up the answer and wrote it out one line at a time to see if  I  could understand what was happening.  I didn't have a prayer of knowing what I was doing.

I don't want to give this book a low rating, but it really didn't help me that much.  Maybe it is me but I need much more detailed instruction than this book provides.

The information is really elementary and nothing new. Anyone with a little common sense could be doing most of what is suggested.

This book is probably great for someone who has had very little exposure to self-help, personal growth information.  I found it too simplistic and way too short.

Maybe my wife and I are below being dummies (we are 70 +).  The author made certain assumptions that are not valid.  Maybe we need something more basic and better organized.  Suggest starting at square-one, which more advanced readers could skip.  Definitions of terms would be nice.

Rudimentary at best, if your a complete beginner to the business world then you might find some value in this book.
