The first two chapters are the obligatory redundant recycling of Linux fundamentals that are the hallmark of lazy authors. Face it: if you don't know what emacs or a shell is, you shouldn't be reading this book; if this is the best opening you can come up with, you shouldn't be writing it.
The authors fail to cover their subjects in sufficient depth. Sockets receive a scant five pages and the examples only treat UNIX domain sockets. Who the hell cares about UNIX domain sockets? Why are there no examples of multi-threaded Internet domain socket servers?
To be fair, the coverage of the linux-specific material is decent, but doesn't justify the price tag. Bottom line: this is a good introduction to the subject of threads and Linux technicals, but will leave you needing more. Go to your favorite bookstore, get a cup of coffee and spend half of an afternoon reading the book in the store and saving yourself ...
First section: Getting started. If you've ever written program in Linux, you'd be familiar with things in this section. It acts as a good reference to things like using GCC, makefile, GNU debugger, etc.
Second 3 and 4 dive into processes and thread. The author spend decent amoung of time explainning the differences between the two, and how both of them work internally. Fork() system(), exec() pthread_create() and other functions are covered in details. The author also give enough word on how to clean things up.
Some system calls are discussed, as well as how linux interacts with devices (/dev) and the /proc directory. Security was given a full chapter in the book. Sure there could have been more on writing secured codes, but it really is out of the scope of this book.
The author gives simple examples as he progresses, and there's one big example at the end that would give you a extremely clear idea how all the things mentioned in the book can be integrated. The GNU http server is one of the best example I'd seen in programming books.
This book is one of the best written Linux programming book.
So in addition to discover how typical intermediate/advanced programming tasks were handled in Linux I also learned a lot more on how the system works.
No shell programming here - only C. Keep your Linux box close by when reading!

Mark Twain's,The Adventures of Tom Sawyer, tells about a boy loving and living his life to the fullest. Tom Sawyer is the kid that the world has seemed to forgotten. He is the kid who always get in trouble but continues to have fun with life. In this book, Tom does everything from being engaged, to watching his own funeral, to witnessing a [death] and finding treasure. Twain's creative character finds fun everywhere in his little town in Missouri, as do his friends. The storyline is basic, but it is a piece of the past that everyone should hold on to.
In The Adventures of Tom Sawyer, I learned mainly two things. The first thing I learned was that you can make life fun with just about anything if you use your imagination. Life is too short and precious to be wasted. I also learned that where you least expect it [help or protection], you might just get it. This book was just amazing-filled with unique characters, exciting events, and how a town can pull together to help those in need.

This book is amazing.. If you want tips, and hints, and behind the scene things this is the best place to get it! It takes you though the "world" telling you about places to eat, and what rides have lines when, and hints. This is a great book for those who have a family or travel alone. It will help you with planning out your trip. One thing that I thought was great was the hint in the books about the monorail! You'll have to get the book to see what I mean! But it's worth it!
They have lots of pictures, and lots of information. I HIGHLY suggest this book for disney fans, and personally everytime I get a new one. i can't wait to walk thru the turnstyle into the magic kingdom. I love that disney air!
thank you :)

(1) Repeated Contents: Materials about Servlet, JSP, EJB, JNDI, JDBC, XML, etc are repeated over and over many books. This could waste time, money, and papers for both Wrox and readers.
(2)Books or Articles?: I asked myself: is Wrox publishing books or articles? Each book is written by many authors and the book's flow is inconsistent. The assessment that it is not a book but a collection of articles may partially true. It is true that a book if written by a team of authors could speed up the process of releasing it, but if Wrox editors and coordinators have to do their better jobs.
I suggest that Wrox should review its strategy of publishing books to avoid the repeating of materials over and over and thus bring down the cost associated with publishing the books. The final result is: readers and publisher will both save time and money. Otherwise, readers will loose their belief with Wrox.
Why do I make the above conclusion? Let me give you my general impression of the book first. A theme repeated in several of my recent reviews on books from Wrox is about the problem in coherence associated with multi-author books. Well, having more than a dozen of authors for a single book seems to be a fact of life (for books from Wrox at least) now, as the publication cycle gets shorter. I was rather surprised to find out that the organization and coherence is very good in this book, i.e., there is very little overlap among chapters. Also, this books uses JDBC cleverly to tie other pieces of J2EE together, making smooth transitions from one chapter to another. If you want to know, this factor alone prompted me to add an extra star to the overall rating of the book.
Let's now run down the chapters of this book quickly. The first 115 pages deals object-oriented and database modeling, and can be skipped by any "Professional" developer. Then after your obligatory intro to JDBC API, the next chapter covers the JDBC 2.0 optional package. This is the best treatment of this topic I have seen. Then another chapter is all about SQLJ, another first. The effort of having a chapter on database performance should be lauded, where connection pooling, prepared statements and stored procedures usage are demoed. The reminder of the book is about applying JDBC in various J2EE components, such as JSP, servlets, EJB, JMS, and XML. For this part of the book, even though I accept the fact the proper stage has to be set for each one of them, I still don't believe the book found the right balance between focusing on JDBC and showing what these other technologies are about. A large number of pages are used to teach basic JNDI, servlets, JSP's, and EJB's stuff (remember there is already a book on J2EE from Wrox!). Therefore, it is up to the reader to discover the real nuggets of gold hidden in this pile, which are far and in between in places. I found that some critical issues are not highlighted or details are lacking, such as how to use connection pooling/data sources in servlets, JSP's, and EJB's, the threading issues related to sharing database connections, and good database practices in BMP EJB's. However, the one thing I cannot complain about is that the book did not forget to teach the transaction aspect of EJB with a good depth (there is a short ans sweet chapter on using JTA/JTS inside EJB). There is also a chapter on the brand-new JDO framework, even though the spec is still in a state of flux. Finally, there are 4 case study chapters in the book - although the design and implementation are limited in scope and as a whole those samples do not teach all you need to do know about enterprise scale J2EE system development, they do provide a flavor of how JDBC is used in real world, together with setting up Tomcat, JRun, Orion, and WebLogic to access MS SQL Server and Oracle databases.
Now my overall take of this book. For VB/SQL and pure back-end PL/SQL developers who are eager to jump on the Java express train and need a suitable platform (especially for the ones who learn best from playing with actual code), I recommend this book as one of several you should own. Compared to other JDBC books from say O'Reilly and Sun's JDBC Tutorial, this book is the most up-to-date, contains the most source code, and has the broadest coverage of related topics. But keep in mind some of the advanced topics such as EJB and JMS can be intimidating for new-comers. On the other side of the coin, people who are advanced in various server-side Java technologies are unlikely to benefit a great deal from this book and should look elsewhere for info (for example Wrox's J2EE and upcoming EJB titles).

Then I discovered this book and was so overjoyed to find some authors who had actually taken the time to write useful code samples and to go well beyond where MSDN leaves off.
Their code is very well laid out and designed. They have taken the time and care to turn out a quality product.

Overall, this book is for experience VB developer who is not looking for VB training but the changes and how to deal with them. Good Book.
Fortunately, this book did a nice job of presenting the new concepts, that we all have to look forward to, and backing them up with concrete examples of how we will have to change our current "code thought" to make them work.
I was a bit disappointed with the lack of discussion about some of the larger issues that may present themselves in .NET, like late-binding not being supported; however, all in all, the book covered most other "rumors" that I had heard, and questioned.
One other plus, was the coverage of Object Oriented Programming with VB.NET. Having never programmed C, I was glad to see a good deal of attention given to explaining concepts like "encapsulation" and "inheritance", which I, for the most part was unfamiliar.
I'm very pleased with this book, and have recommended it to several co-workers, who also purchased it and were happy with it. It's a good buy, and it's good preparation material, for what's to come.
Once again, this series has made an outstanding contribution to the lives of people everywhere. In these troubled times, it is truly a blessing that this thoughtful volume has been provided for Christian teens everywhere.
The reason why this series has struck such a chord with readers across generations is the feeling of authenticity it generates within readers. My only criticism is that some of the stories sometimes seem a bit formulaic. A striking exception is found in the story "The Test", which involves the dilemma of a student who cheats on a school exam. The narrative pulls off the rare combination of being impecably written while still ringing true with its audience. As someone who works with young people on a regular basis, I know it will inspire my students for years to come. Thank you.
