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.

For nearly 20 years, since the emergence of PCs, Lotus 1-2-3, and Microsoft Excel in the 1980’s, spreadsheet models have been the dominant vehicles for finance professionals in the business world to implement their financial knowledge. Yet even today, most Corporate Finance textbooks rely on calculators as the primary tool and have little (if any) coverage of how to build spreadsheet models. This book fills that gap. It teaches students how to build financial models in Excel. It provides step-by-step instructions so that students can build models themselves (active learning), rather than handing students canned “templates” (passive learning). It progresses from simple examples to practical, real-world applications. It spans nearly all quantitative models in corporate finance.

This book is an introduction to computer programming using the Java programming language. No prior knowledge of computers or programming is assumed, but the reader must be confident with high school algebra. This book does not claim to completely cover either the Java language or its standard libraries. We have confined the use of the static keyword to testing classes and enumeration classes, to help students avoid non-object-oriented programming, and we have omitted coverage of Java’s features for reflection, packages, multithreading, networking, applets, and graphical user interfaces. Instead, our emphasis is placed on writing programs of high quality using the best techniques, with extensive coverage of design, collection classes, code cliches, verification, testing, general software engineering, scalability, ethics, and recursion (including an application to recursive descent parsing). This book is divided into two parts. At the University of Sydney, each part serves as the text for one semester. We have delayed introducing inheritance to second semester, not because we think it cannot be mastered earlier, but because novice programmers have a lot to learn, and since inheritance can be deferred, we think it should be.

This text exposes the new version of ASP.NET which includes many practical functions and a lot of frequently requested features, including Master Pages, Themes, site navigation, site counters and many more.

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.

The sendmail Cookbook provides step-by-step solutions for the administrator who needs to solve configuration problems fast. Each recipe in the sendmail Cookbook outlines a configuration problem, presents the configuration code that solves that problem, and then explains the code in detail. The book also provides lots of new material that doesn't get much coverage elsewhere--STARTTLS and AUTH are given entire chapters, and LDAP is covered in recipes throughout the book.

Ask network administrators what their most critical computer application is, and most will say "email" without a moment's hesitation. If you run a network powered by Windows 2000 or Windows Server 2003, Microsoft Exchange occupies much of your time. According to Microsoft, 110 million Exchange seats have been deployed, but 60% of you are still running Exchange 5.5. That's a problem, because the difference between version 5.5 and the more efficient Exchange 2000 and Exchange Server 2003 is profound. Don't fret. Exchange Server Cookbook offers you a comprehensive how-to guide to these newer versions of Exchange. You'll find quick solutions for the most common tasks you need to perform--everything from installation and maintenance to configuration and optimization, with proven recipes for the most useful tools and utilities. The book also has solutions to some uncommon tasks (that you may not know are possible) and advanced procedures that aren't part of day-to-day operations. These include tasks for critical situations, such as using a recovery storage group. Our reliable desktop reference even shows you how to write scripts for Exchange management and deployment tasks. That's right. While not every Exchange job can be scripted, many can, and we provide lots of working VBScript examples for accomplishing particular goals. Whatever your particular need, you'll find it quickly, because chapters in this Cookbook are laid out by recipe, with cross references to other pertinent solutions in the book

Features detailed information on database programming, including ODBC and client/server technology. Covers hot new Internet and object-oriented programming features. Teaches beginning- and intermediate-level programmers how to write for the Microsoft Windows operating system using the Visual Basic programming environment.If you have chosen Visual Basic as your programming tool, let me be the first to congratulate you. Visual Basic is by far the most popular programming tool in history, and there are a lot of good reasons for this popularity. When Visual Basic was originally introduced, it was the first development tool that took Windows programming out of the realm of the specialist and brought it to a level where normal, intelligent people could get something useful done. The ideas of drag-and-drop interface design and event-driven programming are almost universal now, but Visual Basic was the first to make them available to the general programmer. There are plenty of Visual Basic imitators now, and some of them are quite good. In my opinion—and I am not alone—Visual Basic is still the leader of the pack when it comes to Windows development tools. You have made a wise choice.

I run FreeBSD on my computers. A lot of my friends run Linux, or at least one of the distributions of it. Naturally, then, we agree that a Unix-style operating system is the right choice, but we disagree on which to use. It's been my impression that the BSD communit{y,ies}, in general, understand Linux far better than the Linux communit{y,ies} understand BSD. I have a few theories on why that is, but that's not really relevant. I think a lot of Linux people get turned off BSD because they don't really understand how and why it's put together. Thus, this rant; as a BSD person, I want to try to explain how BSD works in a way that Linux people can absorb. While there's overwhelming similarity between the operating systems in most cases, there are also a lot of differences. As you probe more into the differences, you find that they emerge from deep-seated disagreements. Some are disagreements over development methodology, some over deployment and usage, some about what's important, some about who's important, and some about which flavor of ice cream is superior. Just comparing the surface differences doesn't tell you anything; it's the deeper differences that both explain and justify why each group does things the way they do.

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.

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.

The Internet is an all pervasive entity in today’s world of computing. To cope with the "wild" Internet, several security mechanisms were developed, among them access controls, authentication schemes and firewalls, as one of the most secure methods. However, firewall means different things for different people. Consider the fable from India about the blind men and the elephant. Each blind man touched a different part of the elephant and came up with a totally different description. The blind man who touched the elephant’s legs described it as being similar to a tree. Another blind man touched the tail and decided an elephant was like a twig. Yet another grabbed the trunk and concluded an elephant was like a snake. To some computer professionals, even to some of those in charge of Internet security, firewalls are just "walls of fire" blocking hackers outside of it. To some others, it is only a form of authentication mechanism. Some other folks consider firewalls to be synonymous with routers. Obviously, a firewall is much more than any of these individually. The problem is only compounded by the fact that for a lot of computer and security professionals, firewalls was touched upon only fleetingly in their academic career, worse, they bumped into it at the computer room. Also, a lot of the important parts and features of firewall are recent innovations, and thus were never covered in an academic career or most of the 1995-1996 firewall books at all, which further aggravates the problem as of right now there is no one single book these professionals can turn to. Their only resource is to peruse a wide array of literature including textbooks, web pages, computer magazines, white papers, etc. This book, the Complete Firewall Handbook, aims to become your companion book, the one you will always want to carry with you, as it does claim to be complete! I can assure you, there may be some similar books on the market, but none is complete as this one, none provides a reference guide as this one. The other titles I know are either discussing a specific technology and strategy or a product. Although you can compare this book to those, as it also covers the firewall technologies, strategies and all the main firewall products on the market, this one goes beyond the scope of the other ones. In addition, it provides a complete reference guide of the various protocols, including the upcoming ones (IPV6, for example) and how firewalling fits into it. In fact, this book adds a next level to your expertise by discussing all the components that makes the Internet, and any other network for that matter, unsecured: it discuss and describes in details all the protocols, standards and APIs used on internetworking, as well as the security mechanisms, from cryptograph to firewalls. Later on the book there is a "reference" section with a complete review of the major firewall products available on the market to date, a selection of tools, applications and many firewall demos and evaluations, which were all bundled together on the CD the accompanies this book. This book is aimed primarily to network administrators, including Web, systems, LAN and WAN Administrators. But it is also target to the new breed of professionals, the so called Internet Managers, as well as to anyone in need of a complete reference book in firewalls. As you read this book you will notice that what separates it from others is that this one is comprehensive, and gives the technical information necessary to understand, choose, install, maintain e foresee future needs involving firewalls and security at a very informal level. It has a conversational style with practical information, tips and cautions, to help the Internet, network and security administrator to cope, and "survive," their tasks and responsibilities. As important as implementing firewalls at your site, it must be preceded of a security policy that takes in consideration services to be blocked and allowed. It should also consider implementation of authentication and encryption devices and the level of risks you are willing to undertake in order to be connected to the Internet. This book will discuss all of these topics and the issues it brings up when dealing with site security and administration. It will go over all the services, such as TELNET, FTP, Web, e-mail, news, etc.
