Книга представляет собой практическое руководство и подробный путеводитель по самым современным и бурно развивающимся Интернет-технологиям и программным средствам.Современная программа – это не монолитный кусок кода, как раньше, а скорее всего – управляемый сценарий, приводящий в действие множество информационных объектов, существующих в виде апплетов, скриптлетов, сервлетов, XML-конструкций, JSP- и ASP-страниц и т.д. Приведенные примеры демонстрируют, как надо правильно применять две ведущие технологии Интернета: JavaBeans/CORBA и ActiveX/DCOM. Используются два основных языка программирования Visual Basic и Java, хотя имеются примеры и на C++, Pascal, LotusScript. Активно обсуждается связь Java и XML.

This book describes an alternate class methodology that provides complete data hiding and fault-tolerant run-time type checking of objects in C programs. With it, you will produce code that contains fewer bugs. The class methodology helps to prevent bugs by making it easier to write C code. It does this by eliminating data structures (class declarations) from include files, which makes a project easier to understand (because there is not as much global information), which makes it easier to write C code, which helps to eliminate bugs. This class methodology, which uses private class declarations, is different from C++, which uses public class declarations. The class methodology helps detect bugs by providing for both compile-time and run-time type checking of pointers (handles) to class objects. This run-time type checking catches a lot of bugs for you since invalid object handles (the cause of a lot of bugs) are automatically detected and reported.

Voice over Internet Protocol (VoIP) is gaining a lot of attention these days, as more companies and individuals switch from standard telephone service to phone service via the Internet. The reason is simple: A single network to carry voice and data is easier to scale, maintain, and administer. As an added bonus, it's also cheaper, because VoIP is free of the endless government regulations and tariffs imposed upon phone companies. VoIP is simply overflowing with hack potential, and VoIP Hacks is the practical guide from O'Reilly that presents these possibilities to you. It provides dozens of hands-on projects for building a VoIP network, showing you how to tweak and customize a multitude of exciting things to get the job done. Along the way, you'll also learn which standards and practices work best for your particular environment.

Teach Yourself COBOL in 21 Days went through many versions before it was right for the job. Several adventurous volunteers agreed to learn COBOL from scratch by doing each lesson as I completed it, and I installed revisions based on their feedback. For the second edition, each day's text incorporated suggestions from the first edition users and then underwent multiple revisions to ensure that it could be easily understood and that the correct gradient approach was used. Concepts are introduced slowly and repeated many times. The first edition included four Bonus Day lessons. This new edition has been extended to include two additional Bonus Day lessons, with emphasis on the year 2000 problem. In many cases, it is difficult to illustrate a programming point by using a full program. The point being highlighted gets lost against the background of all the other things going on in the program. The answer to this is to write short programs just to show how something works. The problem with this approach is that some examples are silly or trivial programs. One of my more determined volunteers frequently showed up at my desk looking perplexed and asking, "I understand what the program is doing, but why would anyone ever want a program like this?" The answer always is, "No one would; the example is only to illustrate how that part of the language works." I have revised each chapter and added specific comments indicating which examples aren't "real" programs. If I've missed any of these, and you see a program that seems to do something silly, irrelevant, or useless, be tolerant. Review the program as an example of how the language works and not as a program that you might use for some purpose. Lots of code is used. COBOL experience comes from writing, reading, and understanding lots of code. Sometimes one point is illustrated by repeating a whole program with only that one point changed.

When I was first asked to do this book, a lot of folks on the team thought ActiveX was some kind of programming language like C++, HTML or JavaStuff. In fact, it's all of them and none of them. ActiveX is a technology—a way of using a computer's environment to communicate over the Web efficiently and reliably. HTML, C++ Visual Basic, DirectX, and many other tools can be used to take advantage of ActiveX technologies. "Why would I want to use ActiveX?" is the question I hear the most. I've got all kinds of answers—a different one for each individual. "To have a professional Web presence." "So people won't have to be techies to use your site." "So everyone's machine can work with your pages." The $40 answer is that it allows you to use OLE over the Web. This means that you can use your Web browser as a front end for your word processor, spreadsheet, database, chat, news, mail, and other applications. With ActiveX, you don't need to have 10 zillion applications installed on your machine. Moreover, you don't need to know how to use 10 zillion applications. When the Web browser tries to load an ActiveX document and you don't have the software required to load it, your Web browser will contact the software distributor over the Net, grab the stuff you need, and install it onto your local machine. If you never use that software again, it will be automatically deleted, freeing up valuable system resources for other uses. After browsing some of the book titles available for computer programming, I found very few like this one. That is because ActiveX is a unique concept in programming. It addresses the issues of networking by relying on standards that have been cussed and discussed by the many standards organizations out there. Microsoft has said that it will release the ActiveX technologies to an independent standards body for continued maintenance, but in fact, most of it is already in public hands.

This third edition of Linux Unleashed is the result of the demand for Linux, and for our books, for which we are grateful. Along with our Red Hat Linux Unleashed and my Linux System Administrator's Survival Guide, we have managed to cover most aspects of the Linux market with books aimed squarely at the reader. As with the first two editions, we have had a lot of help from the fine editors at Sams, and from technical reviewers from the Linux community. Thanks to Grace Buechlein for her fine efforts to get this edition in on time and into production. Thanks to Dean Miller and the rest of the editorial and production staff at Sams for whipping it into shape. The result of all this effort is hopefully a book even better than the previous edition, with more information aimed at you, our reader. Personally, my thanks to Kamran for once again working well with me to produce another book. If all my collaborations were as friendly and easy as this, I'd be a happy writer indeed. To my parents, thanks for understanding the need to stay in front of the computer and not make the trips to visit as often as I would have liked. Thanks to Bill, Phyllis, Roy, Mark, and Guy for providing welcome diversions, companionship, and support through the many long nights spent at the console. And finally, thanks to Yvonne, who knows writing is important to me and lets me get on with the job.

Many of us, especially since 9/11, have become personally concerned about issues of security, and this is no surprise. Security is near the top of government and corporate agendas around the globe. Security-related stories appear on the front page everyday. How well though, do any of us truly understand what achieving real security involves? In Beyond Fear, Bruce Schneier invites us to take a critical look at not just the threats to our security, but the ways in which we're encouraged to think about security by law enforcement agencies, businesses of all shapes and sizes, and our national governments and militaries. Schneier believes we all can and should be better security consumers, and that the trade-offs we make in the name of security - in terms of cash outlays, taxes, inconvenience, and diminished freedoms - should be part of an ongoing negotiation in our personal, professional, and civic lives, and the subject of an open and informed national discussion. With a well-deserved reputation for original and sometimes iconoclastic thought, Schneier has a lot to say that is provocative, counter-intuitive, and just plain good sense. He explains in detail, for example, why we need to design security systems that don't just work well, but fail well, and why secrecy on the part of government often undermines security. He also believes, for instance, that national ID cards are an exceptionally bad idea: technically unsound, and even destructive of security. And, contrary to a lot of current nay-sayers, he thinks online shopping is fundamentally safe, and that many of the new airline security measure (though by no means all) are actually quite effective. A skeptic of much that's promised by highly touted technologies like biometrics, Schneier is also a refreshingly positive, problem-solving force in the often self-dramatizing and fear-mongering world of security pundits. Schneier helps the reader to understand the issues at stake, and how to best come to one's own conclusions, including the vast infrastructure we already have in place, and the vaster systems--some useful, others useless or worse--that we're being asked to submit to and pay for. Bruce Schneier is the author of seven books, including Applied Cryptography (which Wired called "the one book the National Security Agency wanted never to be published") and Secrets and Lies (described in Fortune as "startlingly lively...¦[a] jewel box of little surprises you can actually use."). He is also Founder and Chief Technology Officer of Counterpane Internet Security, Inc., and publishes Crypto-Gram, one of the most widely read newsletters in the field of online security.

Have you ever asked for an autograph? Been a music fan? Liked watching well-known personalities on TV? Had a favorite movie star? Enjoyed reading about the rich and famous? If your answer is ‘yes’ to any or all of the above, then it’s pretty likely you’ve bought a product endorsed by a celebrity. This fascinating book reveals how ‘celebrity sells’ and is a great read for anyone interested in advertising media, communication and brands. There are lots of ‘how to’ advice, examples good and bad, new insights, ballpark costs and hard evidence of success, plus interviews with top creative talents such as David Abbott, John Hegarty, Peter Souter and John Webster.

These days we look to Wikipedia for the truth. A neat illustration of this occurred not long before I sent up the manuscript of this book to the publishers. A pparently Gordon Brownhad claimed in a speech that he had much in common with the artist Titian, who did his best work in his dotage and reached the age of 90. A few days later, at 12.34 p.m. on 12 February 2009, someone at Conservative Central Office altered the Wikipedia article on Titian so as to reduce his age at death. This allowed David Cameron to go on the offensive at prime minister’s question time the same day. ‘The prime minister never gets his facts right,’ said Cameron. ‘You told us the other day you were like Titian aged 90. The fact is Titian died at 86.’ Two simple, yet potentially significant, propositions lie behind the themes of this book. The first, which I suppose as a historian I have always had in the back of my mind, is that the new – novel institutions, original ideas – usually turns out to be a lot older than we thought. The second, to which I have more recently come, is that, in cultural matters at least, working with one’s peers can get one further than trying to go it alone. I attempt here to illustrate and combine these two points of view by looking at certain historical group projects, and comparing them with another project that was born in the present century – Wikipedia. What sparked off my interest in these particular ‘communities of practice’ in history and on the Internet was the fact that I have myself for several years been a member of just such a community. In our village there is a flourishing archaeology/local history group whose members share the fruits of their efforts and collaborate in joint publications much as wikipedians do, though admittedly the international dimension is somewhat lacking. Recently we too have set up a ‘wiki’ site, www.greatayton.wikidot.com, to which anyone in the group may make a contribution. From these experiences it has been brought home to me that sharing and participation, while immensely enjoyable in themselves, are also just as efficient and productive a way to operate as is the more usual path of the solitary researcher. I want to thank Simon and Tom O’Sullivan and Janus Olsen for reading drafts of the book and making numerous useful suggestions. I should also like to thank my wife Hazel for her patience and moral support during the writing of it.
