The software Premiere Elements 2 by Adobe is loaded with features and enables the user to create high-quality videos. Even for experienced Adobe users, help is needed for understanding all of PE2's amazing tools. This publication, PE2 in a Snap, gets an A for doing a wonderful job with precise and concise instructions and examples. It is not a manual that must be read from start to finish, but rather one where the user can jump in anywhere.

Premiere Elements 3 users, this book is for you too! Being new to video editing, I was wary of a book that was not version specific. No need to worry, this book works well with version 3. Whether you are a beginner or advanced this book has it all. The format makes this book superior to others. The inside front cover has 'Contents at a Glance' index that directs you to the section for a specific task eliminating wasted time searching or reading unneeded info.

Just pick a task and go straight to that section. Each section has a guide on what to read before you begin and other related topics, key terms, tips, and best of all step-by-step instructions with illustrations.

After reading the dry manual, it was wonderful to have an easy to read, concise, and informative book. This book takes the frustration out of video editing and puts in the fun. The authors also have online tutorials that make a good companion to the book at [...].

THE book to get for UNIX programming
Helpful Votes: 0 out of 0 total.
Review Date: 2008-04-29
I am a systems administrator professionally, but I have a need to know the inner workings of UNIX that only seems to be covered in programming books. Specifically relating to certain system calls and interprocess communication methods.

This author has forgotten more about UNIX than I will ever grasp. While this book is dedicated to programming applications in UNIX and understanding the operating system's function calls, I am finding it to be a very handy reference for advanced system administration as well. The book is worth the price just for the chapters on process communication, in my opinion.

I really like the author's writing style. He gets down to business and covers the material without adding a lot of needless fluff or by making the chapters overly wordy.

The book is designed to server as a reference and is well-indexed, which is refreshing to find these days. It's very easy to find a topic you need as not everyone will need the amount of depth covered by each chapter in full.

I wish there were more UNIX books out there like this one.

Review Date: 2006-01-28
This is an exceptional introduction to Unix features that most people won't see in every-day programming. The feature that Rochkind starts with may be the most problematic: portability. There have historically been dozens of Unices (sp?), all slightly different from each other. Even today, there are a number of different implementations in use, with small but maddening incompatibilities between them. Rochkind not only addresses the more common ones, he shows the standards-based ways of dealing with their differences.

After that, Rochkind goes over read/write/open/close/ioctl again, dealing with [a]synchronous subtleties that can mean a 100x difference in performance, backed by code samples and timing measurements. The rest of the book deals with multi-process applications, including communication and distributed processing issues. That includes process groups, interprocess communication (with all its system-dependent weirdness), sockets, and signals.

This isn't for the beginner or for the kernel developer, but never meant to be for either. It is a good, readable introduction to protentially tricky parts of the Unix API. I recommend it strongly to anyone building their own library of Unix references.

I got this book through another online retailer for half the price these U&N people are selling for. You just need to shop around.

I'm an artist, and I have a fondness for the Final Fantasy games. Final Fantasy IX was a challenge for me and after beating it, my claim is that it's the best in the series so far. After watching the last cutscene, I knew I had to have this book. I was very pleased when it arrived and have found it useful even today. FF9 is one of the most franchised game of the FF's(second to 7); I wouldn't waste that if you're a fan of it.

I love Final Fantasy!! I have been a die hard fan since part one was released in 1990. There are several books out that show the visual effects from the Final Fantasy series, but this one is by far the best. It is strait forward, art, from the original designer of FF characters, Yoshitaka Amano. Page for page you will see the steps that he followed making this characters shine.

The main reason that I took one star away was because most of the art in this book is finished up designs from Amano. I am a very big fan of his work, ex. Vampire Hunter D, FF1-6,and 9 adn several other Japaneese work. I enjoy his early sketches better, they are much more fantasy like. But that does not mean that this collection is not beautiful as printed.

This is a beautiful editon to any Final Fantasy collecton or just plain art or drawings collection. Dont pass this up.

When I bought this book, I expected mostly black and white photos and small screenshots from the game, but when I opened it up I was happily suprised with a book full of large, colorful artwork. Being a fan of the game series itself, this book especially appealed to me, as it probably would to many other FF players. But even those who do not play the game will find them selves impressed with the tons of fantastic artwork that fills its pages. I definitely recommened this book if you are a fan of the game or just love great art!

The Art of Final Fantasy IX shows off the artwork from the proclaimed video game. The book contains all types of artwork, from characters designs, transportation designs, backgrounds, enviorments, weapon designs, and 3D renders.

Whether you're a Final Fantasy fan or an artist with interest in seeing great character designs as well as enviorments, this is a great book to look at. It also shows off final renders of the characters in 3D. A must have for any animator's library.

The Publishers Should Be Ashamed of Themselves
Helpful Votes: 0 out of 0 total.
Review Date: 2008-04-25
This is a wonderful book -- but the price is ridiculous. I purchased a paperback copy of "The Awk Programming Language" about 15 years ago, and its price was in the $20 range. Times change, and prices go up, but $73 for a 200-page book, even if it is a hardcover, verges on outright theft.

Which is a shame, because this is a great book, written by the men who developed the language. In addition to a lengthy tutorial, it contains many examples of sophisticated programs that can be constructed from the simple tools provided by Awk. Anyone who supports computers for a living, whether in the Unix or Windows environment, can find valuable ideas here.

But the price: c'mon guys, you've got to be kidding. This book has been in print for 20 years now. You've long since made back the initial costs of publishing it. The authors are famous in computer science circles, and have written many other books. I'm sure they don't need the money. So I have to conclude that this is just a cash cow for the publishers.

If you're looking to learn about Awk, and you're on a budget, I would suggest "Effective Awk Programming" by Arnold Robbins. It's available in PDF form as a free download. If you'd like to support the author, buy a printed copy of the book, as I did. Published by O'Reilly, it's available in paperback at Amazon for about $26.

And if you can find a reasonably-priced copy of "The Awk Programming Language", by all means, grab it. It's a classic. Thanks to the publishers, however, it's a classic that's out of most people's reach.

I am torn about this book. My primary complaint is that this book costs so much. Its only a 200 page paper back book. I'm a sucker for classic books though. This text appears to be the original 1988 version by the authors. The actual text of the book is very good and being written by the authors of AWK, provides a certain view on the language and their intent that was well received. I do carry this book with me as a reference which I have found invaluable in my shell scripting endeavors. This book will give you a solid overview of the language. Be prepared for example references to the world of 1988 such as the USSR. Despite my complaints about the price, I have to admit that I enjoy owning this bit of Unix history and having the authors own words about AWK. From a practical standpoint however, I think that you can learn every bit as much about AWK by learning from freely available internet content on GNU/Linux versions of AWK (gawk). Since I have worked with Unix since about 1984, I have to concede being blinded by a bit of nostalgia. However, AWK is still a vital tool for anyone's shell scripting bag of tricks and this book will help you further develop your skills with AWK if you have only used it lightly in the past.

This is my choice for the answer to the question "If you were stranded on a deserted island and you could have only one programming book which book would you choose?". Over the years I have periodically returned to this book to read or work through for fun. "The AWK Programming Language" may be from 1988 but it is still outstanding! It has an incredible amount of depth for a book of only 200 or so pages. Well-written, concise, with great examples. Truly an enjoyable book to work through.

I've become a big fan of Awk. Some people may tell you that Awk is outdated and no longer useful; not with other languages such as Perl and Ruby available. Well, Awk does one thing and does it well. It does it "fast enough" most of the time, and does it with a very small language.

Perl and Ruby are fine, but if you lean towards "small is beautiful", you must learn Awk. For times when you need it, it's a Godsend. I've used it recently to automatically generate SQL insert statements from some flat files and to do automatic code generation for larger languages.

Some of the best tools have survived the test of time.

In this book, I feel like I learned all the things I need to know about Awk - all the way from beginner to advanced. It's a classic. Not a lot of books get five stars for me. This book fulfills it's goals perfectly, so deserves a perfect rating.

In Unix today, several scripting languages exist: awk, perl, tcl and python. Awk is a small, easy-to-learn, yet powerful programming language, and is language of choice for quick, think- and analyze-on-the-fly tasks. This book is written by the inventors of this wonderful language. It provides an excellent introduction to the language, with many practical examples for day-to-day use. Over many years, it has also served as a good reference to the language. In addition, this book gives concise introduction to numerous fundamental algorithms in computer science (interpreter, calculator, parser, sorting, graph algorithms, ..), which I consult for complex tasks even today.

Always a joy to read! Highly recommended.

'Beginning ASP .NET 2.0 E-Commerce in C# 2005: From Novice to Professional' by Cristian Darie and Karli Watson is one of the most unique and important books out there for anyone that is developing an E-Commerce site with ASP.NET 2.0. Starting from scratch, the authors step by step show you how to get a site running and WORKING well and efficient. Packed with 650+ pages of material, the authors break the steps down in logical parts, show how they go about the work to be done, and then provide the code which does the dirty work. Not only is it helpful, but it's a joy to follow the steps as so much of the curtain is pulled away to show the developer how to get the job done. This is easily one of my favorite Apress books that I have seen. One of the nicest things about the Apress line of books is the fact that they write and publish books that no one else seems to and this is a perfect example of this. I'll close with a chapter overview for your inspection:

01. Starting off
02. Laying Out the Foundation
03. Creating the Product Catalog: Part I
04. Creating the Product Catalog: Part II
05. Searching the Catalog
06. Improving Performance
07. Receiving Payments Using PayPal
08. Catalog Administration
09. Creating a Custom Shopping Cart
10. Custom Orders
11. Making Product Recommendations
12. Adding Customer Accounts
13. Advanced Customer Orders
14. Order Pipeline
15. Implementing the Pipeline
16. Credit Card Transactions
17. Integrating with Amazon

Tack on 2 appendixes to the end and you have a MUST-HAVE book for anyone that is looking to achieve the same goals that this books does!!

Great ASP.Net 2.0 E-Commerce Primer/Reference

Review Date: 2006-11-09
This book covers it's topic E-Commerce very well. It also takes advantage of the new features found in ASP.Net 2.0 including some of the new ADO features. If you are getting ready to setup an E-Commerce site I highly recommend this book. I also recommend it for beginning developers wanting to know more about ADO and database design.
The authors have a great approach to design that anyone doing E-Commerce would do well to follow. Better yet they mention the pros and cons of different approaches and explain why they chose their approach. I've been thrilled to learn some new strategies to improve performance that I hadn't considered before as well as some new features in ASP.Net and ADO 2.0 that I wasn't aware of.
The only negative, for me, is the database as well as ADO basics this book spends many pages covering. However there's plenty of worthwhile content to justify the price. So if you are familiar with database design and have a working knowledge of ADO you can just skip past those pages. I do recommend you skim thru them though as, like me, you may learn some new 2.0 features you weren't aware of.
The book covered all my E-Commerce questions: catalog design, how to scale up/performance considerations, SSL, Security issues, credit card processing, and costs involved. They even point you in the direction of a few recommended credit card processing businesses. Best of all they approach the site creation in such a way you can quickly get up and going and then later on focus on fine tuning payment options and really making the site standout with features.

This book is quite thin, and yet it includes so much. The open mind towards competing technologies is important, we should all look at facts in an objective way. The book gives an excellent view on COM, CORBA and the differences between them. It also shows programming examples (not in depth) and explains things like "push" technologies very good. I would expect the first book in this subject (side-by-side approach) written by a technician, to be too detailed, with a poor language and not very educational. I was very wrong. An amazing book!

I come from a routing shop - never having a customer need for Multicast. This book brought me up to speed very quickly on the both the beauty and ease of Multicast. As a tool for my CCIE studies, I felt the first 200 pages were of immense value at helping my studies. I felt Chapter 5 (on DVMRP) was not nearly as valuable as Chapters 6 and 7 (on PIM-DM and PIM-SM).

Some typos I was able to pick out:
page 144 - 2nd line from bottom should read "...it too sends a Graft message to Router C" - not Router D.

page 168 - 3rd line on the 1st paragraph should read "...SPT to pull the (S2, G) traffic down to the RP..." - not (S1, G).

There are some other typos, but they are few and far between (but I'm not an expert on multicast!). I have heard of this book being talked about as the 'bible' for multicast - I can see why.

I give this book 5 pings out of 5:

I was skeptical about buying a book this old, but I just finished it and am still slightly amazed at how little has changed in multicast technology in ~8 years. I have read Doyle's multicast coverage, listened to InternetworkExpert's excellent "class on demand" (CoD) on the topic many times, and worked through over half of their 20 CCIE lab scenarios, all of which have multicast sections. This doesn't make me an expert by any means, but I know enough now to recognize that the material in this book is still worth reading.

The differences between this book and Doyle's (2004) are:
- Williamson dedicates a lot more effort to explaining the mroute table. This was my single biggest stumbling block in multicast routing
- Doyle, IMO, gives IGMP a better treatment
- Doyle goes over mtrace and mstat
- Williamson spreads the information out over more pages via liberal usage of config snips and diagrams, often one per page. This allows him to go into *brutal, painful and excruciating* detail about every line in the mroute table, every flag, every state transition, etc.
- Williamson does a more thorough job of explaining exactly what happens in PIM-SM networks (100+ pages to Doyle's ~25)
- Doyle goes over Anycast RP and gives a better explanation of MSDN, which appears to have been rather cutting edge when Williamson put finger to keyboard

I finished the book in about a week of serious effort, but I skipped the following chapters (Cisco has not put much effort into the technologies described), leaving me with about 400 pages of groovyness:
DVMRP
CBT
MOSPF
Connecting to DVMRP Networks
and several sections of other chapters

To be sure, some things have changed. I didn't see any mention of the "ip pim autorp listener" command, which negates the need for sparse-dense mode when configuring Auto-RP (can't recall if Doyle mentioned that either). Also, in current versions of IOS one *does* need to specify the RP on the RP itself, whereas Williamson (and Doyle) explicitly say this is not the case (they were both right at the time of print, Cisco has changed this). Overall however, I would say that easily >95% of the material is solid here.

So which book to buy? Well if you're serious about the CCIE and/or running a multicast network you'll get both, and read them both several times. I do hope Williamson updates the book though, as he alludes to several draft proposals, and gives a "state of the multicast internet" address that I would like to know more about without digging through two dozen RFCs. Also, the few things that have changed would be a boon to the book.

May well be the best multicasting book available

Multicasting is truly a technology solution in search of a problem. Excepting highly specialized conferencing applications (a few of which are mentioned here) it is difficult to see how multicasting can be a money-making service for carriers and providers, and the protocols have yet to really penetrate to wide deployment. That said, knowledge of this separate realm of IP networking is a must for any professional in the telecom space.

I'm glad to say that this book rewards determined scrutiny. As a technical writer supporting a very complex product line that has recently added PIM-SM to its bag of tricks, I've found this book painstaking and tremendously informative. You will need to understand IP networking before approaching this title; on the assumption that you do, you will fully understand shared trees, SPTs, and their combination in PIM to an absolute fare-thee-well. My focus when reading this book was on IGMP and PIM-SM, so I have not read absolutely every page of this title. However, Williamson breaks the processes down packet-by-packet for each protocol in the multicasting suite in almost excruciating detail. Advanced coverage of topics such as registration, pruning, and Rendezvous Point behavior means that you will have complete mastery of Cisco multicasting, and for any platform that conforms to the standards, by the time you are finished.

This is an excellent, excellent effort in what I think is a consistently solid networking series.

Multicast has for several years been used in LAN environments to easily exchange information among users, especially in educational and academic research environments. The advent of audio and video conferencing has increased its use in these environments, and it is now making its presence known in WAN and Internet environments. This book gives an overview of the how to implement IP multicast on Cisco devices, and does a good job in that regard. Readers with a general knowledge of networks, even those who have not administered Cisco devices explicitly, can gain much from the book. This reviewer was not interested in the actual implementation of Cisco multicast networks, which is covered in Part 3 of the book, and so this review will concentrate on the other three parts of the book. These parts are mostly descriptive, but they do discuss some of the performance issues involved with the deployment of IP multicast, although nowhere in the book are test cases discussed, even though their inclusion would have been extremely helpful. Multicasting by itself is not a complicated phenomena to understand and use, but when it is deployed over Layer 2 or when coupled with QoS some interesting issues can arise. This reviewer was mostly interested in traffic engineering in multicast environments, and the author spends an entire chapter on this topic.

The book begins with a history of multicast and the MBone, the latter of which is a collection of Internet routers and hosts that are interconnected and are able to forward IP multicast traffic. IP multicast is of course an unreliable transmission mechanism, based as it is on UDP. Along with stating the assigned scope of the multicast addresses over IP, the author also reviews the scheme for multicast MAC addressing. The MAC address mapping will cause a CPU performance hit though since the CPU will have to be interrupted in order to deal with all 32 of the IP multicast groups. This arises since the IP multicast address information cannot be mapped into the available space of the MAC address space. There is a 32:1 address ambiguity when an IP multicast address is mapped to a MAC address.

One can summarize the properties of the multicast routing protocols discussed in the book straightforwardly:

PIM (Protocol Independent Multicasting) can run in three different modes, namely Dense (DM), Sparse (SM) and Sparse-Dense. A router will always forward multicast traffic on a dense mode interface unless all the PIM neighbors of the interface prune themselves from the multicast tree. Multicast traffic will be forwarded on a sparse mode interface only if at least one of the PIM neighbors explicitly joins the multicast tree. In sparse-dense mode, the interface can be running in sparse mode for some groups and dense mode for others. There is a "hello interval" for PIM multicast which is the frequency at which the router will send PIM query messages, the latter of which are used for selecting a PIM designated router. The PIM designated router is responsible for sending IGMP (v1) queries. Bootstrap messages can be forwarded from an interface in PIMv2. This allows all PIM-SM routers in a domain to dynamically learn all Group-to-RP mappings.In PIM-DM, the multicast traffic is periodically forwarded even on pruned interfaces of a source-based distribution tree. This allows the learning of membership changes. This 'state-refresh interval' can be configured on the first-hop routers of the multicast source, allowing the interface to periodically send a state refresh control message down the source-based distribution tree. When doing multicast in an NBMA (NonBroadcast MultiAccess) network, a router will replicate multicast packets for all neighbors configured for broadcast (actually pseudobroadcast to use the author's characterization). To avoid this, one can configure the router in NBMA mode, which will then only allow the replication of packets for PIM neighbors. NBMA mode is only supported by Cisco for SM networks.

DVMRP (Distance Vector Multicast Routing Protocol) does neighbor discovery, where network routing information is exchanged between neighbors. This information consists of Route Report messages that advertise a source network and a hop-count. DVMRP generates two routing tables, one is a multicast routing table to the receivers and a unicast routing table to the sources. When forwarding, a DVMRP router will use the unicast table for RPF (Reverse Path Forwarding) checks and the multicast table for forwarding multicast packets. When doing unicast routing, the router will use the unicast table for the RPF check, but will use a different multicast routing protocol for forwarding multicast packets. There is a metric value associated with a DVMRP unicast route, which is the sum of the interface metrics of a route between the router originating the report and the router in the source network.

For multicast traffic, one can control bandwidth with: 1. Aggregate rate limiting, which sets an upper bound for all multicast traffic being sent on an interface. 2. Mroute table entries wherein each individual multicast stream is set to a maximum rate. 3. `Scoped zones' and multicast boundaries, which prevent multicast traffic with a high rate from traveling outside the provisioned regions. Doing actual multicast traffic engineering is complicated do to the need for calculating the proper RPF (Reverse Path Forwarding) interface (and not the destination IP address). The author discusses in detail some of the techniques that can be used, such as GRE tunnels and `pseudo load-sharing.' GRE tunnels are used to do load-splitting of multicast traffic, which cannot be done otherwise since multicast is allowed only one incoming interface. He also describes how to do traffic conversion between broadcast and multicast, this being allowed for Cisco IOS 11.1 or later. This is a useful capability for networks where the source or the receivers, or both, do not support IP multicast.

This is the best multicast book on the market. It is a must have whether you are preparing for the CCIE Lab or just want to understand multicast.

The explanation was simple and clear. There are tons of configuration examples covering pretty much all kinds of scenarios. The author actually explained every single line of the configurations.

I bought this book for my Lab exam, and after two days of reading, 99.99% of my questions were answered (the only one I still have is I actually made PIM-DM work in a hub-spoke frame relay network. The prune message from one spoke was actually seen by the other spoke, I don't know why the hub would forward it out).

I have to admit this is one of the best books I've read for a long time. Just like Jeff Doyle's TCP/IP Routing is the Bible of IGP, this book is the Bible of Multicast.

I'm currently taking a class in PHP/MySQL and it's use in eCommerce, and this book has really helped me along the way! The author shows you the ways in which Dreamweaver can help you to reduce your development time, but still produced some really great, dynamic sites. He goes into detail on some of the code as well, which is helpful. Additionally, the author is very honest and recommends other resources for items he covers in a limited manner. If you want to learn more about connecting to a database or just using PHP for simple mailing forms, as well as some nice CSS tips, this book is for you!

it is an excellent book. I'm not sure what exactly I actually expected from a book that has Dreamweaver, CSS, AJAX ad PHP (and MySQL) in its title. But one thing is for sure - this book is truly great because this book does something that a lot of other technical books do not do - it teaches you to use several technologies in a chronological way, by adding functionality to the same web site. You do not learn things by following many unrelated examples, but rather by following a step by step instructions which will lead you to the final product - a functional dynamic web site. I find this system of teaching to be the best, because it shows you the actual process of implementation of the techniques and technologies and how they work together on the same page. Teach by example. But beware, that this concept of teaching does not exactly explain the why's, but rather concentrates on the how's giving real world examples without pushing the reader to use a certain approach only to later explain why that particular approach was bad and show a good one.
Although this book is intended for beginners in programming, some of the stuff was rather hard to comprehend and you certainly should not entirely rely on this book alone and seek some more examples on the subject, just to give you more clarity. And you certainly should know your way around Dreamweaver. The author will give you a quick overview of the work environment and CSS, but this is not the book you want if you can't work with Dreamweaver at least at the upper beginner level. That applies to your knowledge of CSS too.
This is not a quick study book. You will see immediate results, but to understand what is going on and be able to use the knowledge to make your own applications will require a lot of determination and effort on your part. I personally like that - no pain, no gain. However, if you have the will to go through a lot of coding, reading, looking for that missing semi-colomn in your code and do not want to be bothered by childish examples and exercises, your perseverance will be awarded and this book will make you a better web developer. It's 5 stars and a big THANK YOU MR POWERS from me.

I have read many books on programming. While I have gleaned some value from just about every book, the page-count-to-learning ratio hasn't been great. And on a few occasions, I hit a roadblock where I simply wasn't getting what author was telling me I should be completely proficient with at that moment...anyone else experience that?? Makes me feel like a coloring-by-the-numbers code monkey. I've gone back to some of those books once I have gained some proficiency on the topic (elsewhere) to find that those authors made things unnecessarily complex. Who knows why, but it sure pisses me off.

I give you this background, so that when I say that this book is absolutely without equal in delivering actionable, easy-to-understand content on almost every single page, that is no exaggeration. I lost count of the number of times I came up with a question, only to read the very next sentence which usually went something like this, "...you are probably wondering why this is the case. Here's why..." It was incredible! And the exercises start to ween you off of the minutia at precisely the right pace (for me, anyway). It was a great confidence builder when the author wrote, "You should be comfortable with these steps at this point..." and I totally was.

Truly excellent work by David Powers and Tom Muck (who did the technical review). And they've kept their errata/updates site up-to-date with DW CS3, which definitely came in handy as I encountered current-version discrepancies with things like Spry 1.6.

One miss was, the very last exercise did not work for me. After thoroughly reviewing the sample code, my code, etc. I submitted it as errata...waiting for a response.

I find the book "Fundamentals of digital logic and microcomputer design" very useful. I am a Cal Poly student, and took a few courses from Professor Rafiquzzaman. He is an excellent professor. It seems to me that the unproffesional comments by the other Cal Poly student are motivated. He probably took Professor Rafiquzzaman's class and received a bad grade. You should go through the book yourself and make your own judgements. The topics in the book are presented in a very simplified way. It's easy to understand. The CD included in the 5th edition is very handy. I am sure once you go through the book, you will know what I mean.

The content of this is easy for user to understand, and there always an examply in the theory. The author also combine Verilog in this book, so the student can understand Digital Logic efficiently before they can start Verilog. This will help most student understand the content of both Digital Logic and Verilog.

Makes understanding the subject simplistic. It tells you what you need to know and tries not to confuse you with all the other garbage some Digital Logic and Microprocessor Design books have in them. I also took a couple of courses with the author and I know that this guy has had a lot of experience with what he writes. He has written training material for certain companies in the industry. I recommended another book that he also wrote, "Preparing for an Outstanding Career in Computers," because he refers to this book in his courses and usually uses the examples from this book as a supplement to the class.

The first half of this book does an excellent job of teaching the background information needed for digital design. Unfortunately, the CPU-specific sections that follow are badly out of date. The author spends altogether too much time describing the 8086 and its family of (ISA-bus-specific) support chips -- devices that are almost never used anymore. It needs to be revised to talk about current technology.
