Linux appliances are computers that serve a single, well-defined purpose. Modern appliances are complex machines, with processors, operating systems, and application software. For example, the Tivo is essentially a Linux-based computer with a single purpose: recording television. While there are books that tell readers how to run Linux on embedded hardware and books on how to build a Linux application, Linux Appliance Design is the first book to demonstrate how to merge the two to create a Linux appliance. Programmers will learn how to build backend daemons, handle asynchronous events, and connect various user interfaces (including web, framebuffers, infared control, SNMP, and front panels) to these processes for remote configuration and control. Linux Appliance Design also introduces the Runtime Access Protocol, which provides a uniform mechanism for user interfaces to communicate with daemons. The accompanying CD includes a prototype appliance - a home alarm system - that supports the book's lessons. The prototype is written using a liberal BSD style license, which allows readers to use and modify the code used in the prototype.

This highly topical text considers the construction of the next generation of the Web, called the Semantic Web. This will enable computers to automatically consume Web-based information, overcoming the human-centric focus of the Web as it stands at present, and expediting the construction of a whole new class of knowledge-based applications that will intelligently utilise Web content. The text is structured into three main sections on knowledge representation techniques, reasoning with multi-agent systems, and knowledge services. For each of these topics, the text provides an overview of the state-of-the-art techniques and the popular standards that have been defined. Numerous small programming examples are given, which demonstrate how the benefits of the Semantic Web technologies can be realised at the present time. The main theoretical results underlying each of the technologies are presented, and the main problems and research issues which remain are summarised. Based on a course on 'Multi-Agent Systems and the Semantic Web' taught at the University of Edinburgh, this text is ideal for final-year undergraduate and graduate students in Mathematics, Computer Science, Artificial Intelligence, and Logic and researchers interested in Multi-Agent Systems and the Semantic Web.
