    But when devices that you've built start to talk to each other, things really start to get interesting. Through a series of simple projects, you'll learn how to get your creations to communicate with one another by forming networks of smart devices that carry on conversations with you and your environment. Whether you need to plug some sensors in your home to the Internet or create a device that can interact wirelessly with other creations, Making Things Talk explains exactly what you need. This book is perfect for people with little technical training but a lot of interest. Maybe you're a science teacher who wants to show students how to monitor weather conditions at several locations at once, or a sculptor who wants to stage a room of choreographed mechanical sculptures. Making Things Talk demonstrates that once you figure out how objects communicate -- whether they're microcontroller-powered devices, email programs, or networked databases -- you can get them to interact. Each chapter in contains instructions on how to build working projects that help you do just that. You will:Make your pet's bed send you email Make your own seesaw game controller that communicates over the Internet Learn how to use ZigBee and Bluetooth radios to transmit sensor data wirelessly Set up communication between microcontrollers, personal computers, and web servers using three easy-to-program, open source environments: Arduino/Wiring, Processing, and PHP. Write programs to send data across the Internet based on physical activity in your home, office, or backyard And much more With a little electronics know-how, basic (not necessarily in BASIC) programming skills, a couple of inexpensive microcontroller kits and some network modules to make them communicate using Ethernet, ZigBee, and Bluetooth, you can get started on these projects right away.

    Generics and the greatly expanded collection libraries have tremendously increased the power of Java 5 and Java 6. But they have also confused many developers who haven't known how to take advantage of these new features.Java Generics and Collections covers everything from the most basic uses of generics to the strangest corner cases. It teaches you everything you need to know about the collections libraries, so you'll always know which collection is appropriate for any given task, and how to use it.Topics covered include:• Fundamentals of generics: type parameters and generic methods• Other new features: boxing and unboxing, foreach loops, varargs• Subtyping and wildcards• Evolution not revolution: generic libraries with legacy clients and generic clients with legacy libraries• Generics and reflection• Design patterns for generics• Sets, Queues, Lists, Maps, and their implementations• Concurrent programming and thread safety with collections• Performance implications of different collectionsGenerics and the new collection libraries they inspired take Java to a new level. If you want to take your software development practice to a new level, this book is essential reading.Philip Wadler is Professor of Theoretical Computer Science at the University of Edinburgh, where his research focuses on the design of programming languages. He is a co-designer of GJ, work that became the basis for generics in Sun's Java 5.0.Maurice Naftalin is Technical Director at Morningside Light Ltd., a software consultancy in the United Kingdom. He has most recently served as an architect and mentor at NSB Retail Systems plc, and as the leader of the client development team of a major UK government social service system."A brilliant exposition of generics. By far the best book on the topic, it provides a crystal clear tutorial that starts with the basics and ends leaving the reader with a deep understanding of both the use and design of generics."
