The Intel Microprocessors 8086/8088, 80186/80188, 80286, 80386, 80486, Pentium, and Pentium Pro Processor Architecture, Programming, and Inter- facing ReviewI have read the first 140 pages of this book, and I really like it. So far, I have the following comments.
Good points:
1.) It covers both real and protected mode from the start. Other books wait until the middle of the books before they cover protected mode.
2.) Assembly language command mechanism are explained in great detail. The author explain exactly what's going on. How the data moved from memory to register, register to register, how the memory in a computer is organized, how exactly PUSH and POP command works etc. There are lots of diagram that illustrate his explanations.
3.) It covers from 8086 to Pentium II hardware architecture. Many books are strictly limited to outdated 8086 and 8088 processors.
4.) The exercises at the end of each chapter increases my understanding of the subject and answers to even numbered problems are available at the end of the book.
Bad Points:
1.)Assembly language and processor architecture are hard subjects. You have to read each chapter several times before you can get a good grasp of the topic.
2.)Some of the topic presented by the authors can not be easily understood until you read the subsequent chapters.
One suggestion for people who read the book: Make sure you know how to convert binary, hexadecimal and decimal number. You have to know these otherwise you can get lost. Some basic understanding of logic gates is also helpfull!The Intel Microprocessors 8086/8088, 80186/80188, 80286, 80386, 80486, Pentium, and Pentium Pro Processor Architecture, Programming, and Inter- facing OverviewFor Introductory level Microprocessor courses in departments of Electronic Engineering Technology or Electrical Engineering.Keeping students on the forefront of technology, this timely text offers a practical reference to all programming and interfacing aspects of the popular Intel family of microprocessors.

Postfix: The Definitive Guide ReviewAfter many years bashing my head against sendmail in all it's gory details I had amassed a fair amount of knowledge and documentation on handling the Mail Transfer Agent (MTA) in Linux and Mac OS X. This caused a fair amount of teeth gnashing when I discovered it had gone the way of all flesh in OS X Panther to be replaced with Postfix.
Fortunately, my first needs were simple and I came to realise that Postfix was a much easier system to install and maintain. Now that my needs are more complex, I was glad when this book hit my desk at exactly the same time as I started upgrading the corporate servers from Mac OS 9 to OS X Server.
Postfix: The Definitive Guide seems to fit the bill. It is a well-written and well-constructed guide to mail systems in general and Postfix in particular.
The book starts with a good overview of the underlying technology in Chapters 1 and 2. I can't blame Dent for my slight confusion in the section on addresses and headers - having RFC822 superseded by RFC2822 was just a little too much coincidence for this particular "bear of little brain." He then follows it with a chapter discussing Postfix's architecture, important since Postfix uses a much more modular approach than the sendmail monolith, with each part of the mail handling process a different executable and the single queue turned into five.
Once the background is well covered, Dent then gets onto the nitty-gritty of configuring and administering Postfix. He has certainly covered everything I needed, including spam handling, multiple domains, relaying, SASL authentication and using LDAP. Once I'd finished grokking all that, and getting it integrated into my servers, I had a corporate email system up in three sites that replaced and improved upon a couple of thousand dollars worth of proprietary dreck. Happy is an understatement.
Dent's writing is sometimes a little patchy, though never bad. The technical detail does seem overpowering in places, though, and I occasionally found myself reading a section through more than once with a configuration file open in front of me. There are certainly spots where a little more hand holding and care with the writing would have been appreciated. (If you are a little more cognizant of the interstices of mail systems then you may not have the same problem.)
I did, however, appreciate the appendices enormously. The four appendices cover configuration parameters, Postfix commands, installation, and an FAQ. My system came with Postfix compiled and installed just as I required it so I didn't get a chance to thoroughly test out Dent's installation procedure (though it looks good); the other three continue to be useful.
If you want to have a look for yourself, then the usual O'Reilly page is complete with a table of contents and index, but this time no example chapter is provided (how come, O'Reilly?). You can also get an expanded version of the FAQ in Appendix 4 from Dent's website. A better example of Dent's writing style is an excellent article on troubleshooting with Postfix logs at O'Reilly's Onlamp.com.
This is a good book, Dent has explained the underlying methodology and use of Postfix well, taken the reader through all aspects of this MTA system and explained both the why and the how. I would recommend this book (and, as a result Postfix) to anyone looking for an MTA and a guide to configuring and running it.Postfix: The Definitive Guide OverviewPostfix is a Mail Transfer Agent (MTA): software that mail servers use to route email. Postfix is highly respected by experts for its secure design and tremendous reliability. And new users like it because it's so simple to configure. In fact, Postfix has been adopted as the default MTA on Mac OS X. It is also compatible with sendmail, so that existing scripts and programs continue to work seamlesslyafter it is installed.Postfix was written by well-known security expert Wietse Venema, who reviewed this book intensively during its entire development. Author Kyle Dent covers a wide range of Postfix tasks, from virtual hosting to controls for unsolicited commercial email.While basic configuration of Postfix is easy, every site has unique needs that call for a certain amount of study. This book, with careful background explanations and generous examples, eases readers from the basic configuration to the full power of Postfix. It discusses the Postfix interfaces to various tools that round out a fully scalable and highly secure email system. These tools include POP, IMAP, LDAP, MySQL, Simple Authentication and Security Layer (SASL), and Transport Layer Security (TLS, an upgrade of SSL). A reference section for Postfix configuration parameters and an installation guide are included.Topics include:Basic installation and configurationDNS configuration for emailWorking with POP/IMAP serversHosting multiple domains (virtual hosting)Mailing listsHandling unsolicited email (spam blocking)Security through SASL and TLSFrom compiling and installing Postfix to troubleshooting, Postfix: The Definitive Guide offers system administrators and anyone who deals with Postfix an all-in-one, comprehensive tutorial and reference to this MTA.

PC Interrupts : A Programmer's Reference to BIOS, DOS, and Third-Party Calls ReviewNobody else could write a book like PC Interrupts, than Ralf Brown & Jim Kyle. This book is not only a reference, it is written from programmers for programmers and all the needs of an experienced developer. The title speaks for itself, the book is a milestone in Computer Literature and traces a long period of general PC development. May be, that the most of the stuff is dated, but anyway there's often enough a good reason to read some and the enormous information impact makes the book valuable for every programmer, today and forever. I recommend the book particularly!PC Interrupts : A Programmer's Reference to BIOS, DOS, and Third-Party Calls OverviewPC programmers use system calls from many different sources, MS-DOS, the ROM BIOS and various APIs (application program interfaces) such as Windows 3.1, NetWare and DESQview. This updated second edition represents one of two volumes published to replace the first edition, the other being "Network Interrupts". They provide programmers with a concise description and other essential information on each system call. In addition, the books are sources of information on potential conflicts between calls from different APIS. This edition has been updated to include DOS 6, Windows 3.1, DR-DOS 7 and other APIS.

Automating Linux and Unix System Administration (Expert's Voice in Linux) ReviewI bought this book expecting it would describe and demonstrate a variety of automation methods and tools. The book surprised me -- pleasantly. The majority of the book focuses on CFEngine (www.cfengine.org) and how to use it to manage server configurations, deliver applications automatically to those servers, and enforce a consist policy across the servers.
The book goes into some depth demonstrating how cfengine works. It has chapters on configuration, setting up a production environment, setting up automated installations, and delivering applications using cfengine.
There are smaller chapters on SSH, Nagios (and using CFengine to deliver it), and improving server security using cfengine.
The book is about 400 pages and is packed with content. There are interesting facts and config bits in every chapter.
With the exception of the cfengine manuals, there are no other books on the market today which provide a detailed, comprehensive look at cfengine...until now. If you are using, will use, or have questions about what CFengine can do, get this book. I'm happy I did.
Automating Linux and Unix System Administration (Expert's Voice in Linux) OverviewThis is the second edition of a title that succeeded before its time - this second edition comes at a timely juncture for Linux administrators and will become a key reference.If Linux administrators want to build a small or medium-sized network or datacenter, this is the book to show them how to do it by automating the build process. Linux datacenters have multiplied over the last 5 years and literally thousands of Linux system administrators on all 5 continents need this information.

Threads Primer: A Guide to Multithreaded Programming ReviewThis was an excellent book with detailed coverage of threads programming even down to how various hardware architectures affect multithreaded program behavior. However there is a more current edition under a different name (Multithreaded Programming with Pthreads) by the same authors that is more current that I would recommend instead (everything in this book is in the newer book).Threads Primer: A Guide to Multithreaded Programming OverviewFor programmers, system architects, and technical programmer managers.Providing an overview of the Solaris and POSIX multithreading architectures, this book explains threads at a level that is completely accessible to programmers and system architects with no previous knowledge of threads.

C++ GUI Programming with Qt 4 ReviewThis book is one of the best reference materials I have read. The author is clearly not regurgitating Trolltech's documentation but elegantly cranks out a series of real life applications.
I read this quite differently than other 'introductions to'. In fact, I initially ignored it. But when it came time to build my own code, I kept running into questions as to how a particular programming problem was approached 'the right way'. A reference manual only shows you what you can do and there is an abundance of literature out there which will show you all the minutiae of endless variations of function calls - theory.
This book showed me how to properly put together FTP sessions, build a graphical directory tree of my own and much else. I am less interested in 'what does the framework offer?' but 'how do I best accomplish this task?'. This only an author with real-world programming experience can answer. This book's teaching by example will get you started quicker in Qt than anything else I have seen.
The other book 'Introduction to design patterns in C++ with Qt4' is also recommended but fairly high-level. The two together make a great combination.C++ GUI Programming with Qt 4 OverviewQt 4 is radically different from earlier versions of Qt, with lots of new features and many small changes everywhere in the API. For customers porting applications from Qt 3 to Qt 4, this is bad news; but for us, this is good news, because it means that owners of the Qt 3 book will want to buy this one as well. Those who buy this book will: [1] Learn how to program Qt the right way, i.e. with the grain of the tool. [2] Learn standard patterns of Qt programming, from basic tasks like creating a file menu with a recently used files list to more complex tasks such as presenting data to the user through the user interface, and providing the user with the ability to interact with their data. [3] Learn how to extend Qt to meet their needs, for example, through subclassing and by composition. [4] Gain insight into programming in general and into graphical user interface programming in particular.

Topics in C Programming, Revised Edition ReviewThis is an excellent book in advanced C programming techniques. Although it is an advanced text, the author explains each method in detail and strengthens understanding of key elements in C programming. A number of weaknesses prevent this book from rating 5 stars: the last chapter is number 9 (which makes it harder to use in a 16 week semester), the second chapter is really about four chapters (structures, pointers, linked lists, other topics), the chapter length ranges from 4 pages (chap 1) to 82 pages (chap 2), and it hasn't been updated since 1991. This book is relatively easy to read, but sometimes runs into awkward sentences. The awkward sentences can be directly attributed to required nomenclature (returns...returns...returns...) which can leave the reader wondering if returning to that sentence will improve understanding of the concept. The examples and exercises are wonderful. The examples build a base of programs that should be useful to every programmer. The examples also show the differences in methods achieving the same result and explain the reasoning behind methods that are better (fewer clocks, more efficient use of memory, etc.). I really enjoyed reading this book and wish an updated edition was available, which led me to this website and book review.Topics in C Programming, Revised Edition OverviewTopics in C Programming Revised Edition Topics in C Programming, Revised Edition is designed to teach computer programmers how to program in this powerful, yet easy-to-master language.
