Master Java 5.0, object-oriented design, and Test-Driven Development (TDD) by learning them together. Agile Java weaves all three into a single coherent approach to building professional, robust software systems. Jeff Langr shows exactly how Java and TDD integrate throughout the entire development lifecycle, helping you leverage today's fastest, most efficient development techniques from the very outset.

The Concise Guide to DNS and BIND provides the technical depth and expert-level information needed to understand and administer DNS and BIND. Domain Name System (DNS) is a distributed Internet directory service. It is used mainly to translate between domain names and IP addresses, and to control Internet email delivery. Most Internet services rely on DNS to work, and if DNS fails, Web sites cannot be located and email delivery stalls. BIND (Berkeley Internet Name Daemon) is an implementation of the Domain Name System (DNS) protocols. Some of the topics covered are setting up a DNS server and client, compiling and configuring BIND, and setting up root servers on private networks. The Concise Guide to DNS and BIND also features expert knowledge on firewall rules, Dynamic DNS (DDNS), debugging and logging, plus new features in BIND 8.2.2. The book also offers introductory information on BIND 9.

This volume grows out of an initiative in the World Bank on resource allocation and purchasing (“RAP”), which started in 2000, and continues to publish articles and books related to strategic purchasing. The initiative emerged from such questions in developing economies as: Why do individuals need help in purchasing health services from providers? Is the “middleman” really necessary? Can people not just buy health services in the same way they would go to the local market to buy bread, milk, or fruit—especially since, throughout most of history, that is what most people did? When sick, they contacted local healers directly. Public policy historically was limited largely to protecting the sick against charlatans and was enforced through ethical codes such as the Hippocratic oath. There was no expensive technology, and most serious conditions led to death. Loss of employment and burial costs were the most expensive parts of illness. With industrialization and the scientific revolution, all this changed. As understanding about the causes, prevention, and treatment of illness expanded, interventions become more complex and expensive. Health care was no longer the exclusive domain of traditional healers.

Robert J. Lang, one of the worlds foremost origami artists and scientists, presents the never-before-described mathematical and geometric principles that allow anyone to design original origami, something once restricted to an elite few. From the theoretical underpinnings to detailed step-by-step folding sequences, this book takes a modern look at the centuries-old art of origami.
