Bug Patterns in Java presents a methodology for diagnosing and debugging computer programs. The act of debugging will be presented as an ideal application of the scientific method. Skill in this area is entirely independent of other programming skills, such as designing for extensibility and reuse. Nevertheless, it is seldom taught explicitly. Eric Allen lays out a theory of debugging, and how it relates to the rest of the development cycle. In particular, he stresses the critical role of unit testing in effective debugging. At the same time, he argues that testing and debugging, while often conflated, are properly considered to be distinct tasks. Upon laying this groundwork, Allen then discusses various "bug patterns" (recurring relationships between signaled errors and underlying bugs in a program) that occur frequently in computer programs. For each pattern, the book discusses how to identify them, how to treat them, and how to prevent them.

Those of you who run networks on Windows 2000 know the benefits of using Active Directory for managing user information and permissions. You also know what a bear it can be. The newer version included with Windows Server 2003 has over 100 new and updated features to simplify deployment, but once it's in place many system administrators still find Active Directory challenging. If you're among those looking for practical hands-on support, help is here with our new Active Directory Cookbook for Windows Server 2003 & Windows 2000, a unique problem-solving guide that offers quick answers for both versions of the directory. The book contains hundreds of step-by-step solutions for both common and uncommon problems that you might encounter with Active Directory on a daily basis--including recipes to deal with the Lightweight Directory Access Protocol (LDAP), multi-master replication, Domain Name System (DNS), Group Policy, the Active Directory Schema, and many other features. Author Robbie Allen, a Senior Systems Architect at Cisco Systems and co-author of our Active Directory tutorial, based this collection of troubleshooting recipes on his own experience, along with input from Windows administrators throughout the industry. Each recipe includes a discussion to explain how and why the solution works, so you can adapt the problem-solving techniques to similar situations.

This practical reference guide offers hundreds of useful tasks for managing Windows 2000 and Windows Server 2003, Microsoft's latest server. These concise, on-the-job solutions to common problems are certain to save you many hours of time searching through Microsoft documentation. Topics include files, event logs, security, DHCP, DNS, backup/restore, and more.

Из чего состоит дистрибутив Linux? Как он работает и почему? Что умеет, и как этими умениями управлять? Кто они такие, эти таинственные «линуксо- иды»? пингвины? Если писать программы, то про что их писать? И вообще— что на самом деле такое: «Linux», «Дистрибутив», «Сообщество», «Свободные программы» наконец? Обо всём этом и о некотором другом и написано во второй половине нашей книги. Раз уж приходится управлять таким сложным созданием, как пингвин, и тем более—таким сложным инструментом, как компьютер, без знаний не обойтись. Если вы не считаете поведение компьютера «предопределением природы», и хотите что-то изменить к лучшему, непременно стоит познакомиться с тем, что именно вы хотите изменить. По крайней мере, мы—разработчики дистрибутивов ALT Linux и участники Linux-сообщества—для себя решили начинать именно со знаний.

This book is about patterns for the Java 2 Platform, Enterprise Edition (J2EE). The J2EE patterns documented in this edition provide solutions for problems typically encountered by designers of software applications for the J2EE platform. All the patterns documented in the catalog have been discovered in the field, where they have been used to create successful J2EE applications for our customers. This book describes proven solutions for the J2EE platform with a particular emphasis on such key J2EE technologies as: JavaServer Pages (JSP), servlets, Enterprise JavaBeans (EJB) components, Java Message Service (JMS), JDBC, and Java Naming and Directory Interface (JNDI). We offer solutions for recurring problems for the J2EE platform through the J2EE Pattern Catalog and J2EE refactorings. You can apply these ideas when developing new systems or when improving the design of existing systems. The patterns in this book will help you quickly gain the proficiency and skills to build robust, efficient enterprise applications.

Mike's work takes him to sites in the US and Europe where he teaches Windows programming and helps companies develop and manage Windows-based client/server solutions.

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.

A Web server is the server software behind the World Wide Web. It listens for requests from a client, such as a browser like Netscape or Microsoft's Internet Explorer. When it gets one, it processes that request and returns some data. This data usually takes the form of a formatted page with text and graphics. The browser then renders this data to the best of its ability and presents it to the user. Web servers are in concept very simple programs. They await for requests and fulfill them when received.

Bringing together two areas of computer technology networking and embedded systems this developer's guide offers guidance and examples for each of these, with a focus on the special requirements and limits of embedded systems. Because developing an embedded system for networking requires knowledge from many areas, including circuit design, programming, network architecture, and Ethernet and Internet protocols, developers are given valuable technical information on each that can be put to use right away. Covered are the advantages and limits of using Ethernet to connect embedded systems in a local network, hardware and program code needed to connect an embedded system to an Ethernet network and the Internet, and how to build a network. Also discussed are how embedded systems can use TCP/IP and related protocols and how personal-computer applications can use the protocols to communicate with embedded systems. Developers will learn how their Web server's pages can include dynamic, real-time content and respond to user input.
