Title: How Networks Work (7th Edition) (How Networks Work) Publisher: Que Authors: Frank J. Derfler Jr., Les Freed Rating: 1/5  After reading the reviews on Amazon, i went ahead and bought this book. This book's simplicity is misleading- the author' explanations are neither well thought out or well-written, concepts & basics remain unclear. The illustrations are a fright! Dark colors & unneccesary complexity amplifies the illegibility. I wouldve given it no stars at all, but, that' not an option. It's sad that certain Certifications prescribe this as an essential textbook. I hope there are better, basic books out there which explain network fundamentals. Note for beginners, if you have had no experience with networking, this is not a book for you. Internet searches/sources will explain the basics much better than this publication.

Title: Computer Organization and Design Second Edition : The Hardware/Software Interface Publisher: Morgan Kaufmann Authors: David A. Patterson, John L. Hennessy Rating: 2/5  This book has a good potential in teaching students about computer organization. Unfortunately, the authors spend too much time explaining simple concepts which makes the book very boring and tedious to read. For example: the authors spend 335 pages just to explain basic MIPS assembly languages and computer performance. Those concepts could have been explained in 50 pages at most. Giving too much unnecessary detail won't help me to get a better understanding of computer organization. In fact, I get lost because the main topic was buried inside all the unimportant unnecessary details. This book could have been written in 300 pages, which is about a third of the length of the book, and still gives a clear, to the point, concise explanation of computer organization.

Title: Understanding the Linux Kernel (2nd Edition) Publisher: O'Reilly Authors: Daniel P. Bovet, Marco Cesati Rating: 5/5  My interest Ranges from admin to security to <big focus> drivers. This book (or tome in many peoples eyes) is the utter definition of 'internals explained'. I sat with this book and Linux Device Drivers 2nd Edition (also from O'Reilly) and practically obsessed! It's generally very good for anyone who does /anything/ linux. You will learn how to communicate with the kernel, and get a great explanation of all kernel specific functions. Whether you talk to it, interprocess with it, whatever; this book will be a /major/ help for kernel related tasks, It was for me. As a bonus, in the back you can find all functions and headers by reference and alphabetic. In essence, i was very satisfied and glad i came upon this 'tome'. Hope this helps

Title: The Book of Postfix: State-of-the-Art Message Transport Publisher: No Starch Press Authors: Ralf Hildebrandt, Patrick Koetter Rating: 4/5  Venema's offering of Postfix has emerged as a serious competitor to sendmail. The book describes Postfix's many capabilities and how you can alter these. Simpler than sendmail's notoriously convoluted configuration files. Here, Postfix probably has an advantage, to a sysadmin who is worried about the maintenance issues of using either package. A lot of space in the book discusses Postfix's antispam features. Impressive. These seem to have been built up considerably in this version, compared to earlier iterations. Probably reflects spam's continuing (worsening?) presence. There is the means to verify the sender, which the book claims is Postfix's best antispam method. However, it seems to fail against a computer or user account that has been subverted by a virus, to issue spam under the user's address, which would be still valid. Nor is there a discussion of what has emerged as the best way to use a blacklist of spammer domains. Namely against links in the body of a message. In the latest sendmail, there is an implementation of this. But in this book, as far as I can tell, while Postfix can apply tests against a message body, those are described as content tests. Though this does not necessarily preclude the blacklist test against the links, it should give explicit mention. Because, otherwise, content tests are usually tests of "bad words" or Bayesians or the like.
