Ready to go to the next level with Rails? From examining the parts of Ruby that make this framework possible to deploying large Rails applications, Advanced Rails offers you an in-depth look at techniques for dealing with databases, security, performance, web services and much more. Chapters in this book help you understand not only the tricks and techniques used within the Rails framework itself, but also how to make use of ideas borrowed from other programming paradigms. Advanced Rails pays particular attention to building applications that scale -- whether "scale" means handling more users, or working with a bigger and more complex database. You'll find plenty of examples and code samples that explain: Aspects of Ruby that are often confusing or misunderstood Metaprogramming How to develop Rails plug-ins Different database management systems Advanced database features, including triggers, rules, and stored procedures How to connect to multiple databases When to use the Active Support library for generic, reusable functions Security principles for web application design, and security issues endemic to the Web When and when not to optimize performance Why version control and issue tracking systems are essential to any large or long-lived Rails project Advanced Rails also gives you a look at REST for developing web services, ways to incorporate and extend Rails, how to use internationalization, and many other topics. If you're just starting out with rails, or merely experimenting with the framework, this book is not for you. But if you want to improve your skills with Rails through advanced techniques, this book is essential.

How are businesses responding to global changes in markets driven by changes in technology? Whatever the industry, the trends are familiar: globalization and the rise of industrial conglomerates, mergers and acquisitions, the networking of businesses and markets, outsourcing and shifts in the distribution of resources and production, all reflected in the emergence of new players, new products and services and new forms of competition. As arguably the first knowledge-based business, book publishing provides an ideal setting for the study of challenge and opportunity. The industry is currently experiencing fierce levels of competition, extreme financial pressures, restructuring and the threat of technology-induced obsolescence. Added to these are the challenges posed by new and potential entrants to the market, the emergence of new products and services, new ways of doing business, including trading in virtual markets, and the vulnerability of traditional business models. The suitability of book publishing as a context for researching the emergence of knowledge-based business becomes all too apparent. Through combining primary research with secondary analysis drawn from the relevant literatures, Books, Bytes and Business is both a readable and informative account of business in the knowledge-based economy.

Ideal for those with no programming experience.

Technological advancements in recent years have enabled the development of tiny, cheap disposable and self contained battery powered computers, known as sensor nodes or “motes”, which can accept input from an attached sensor, process this input and transmit the results wirelessly to some interested device(s). When a number of these nodes work together, conceivably up to hundreds of thousands, a Wireless Sensor Network (WSN) is formed. Research in the area of wireless sensor networks has become increasingly wid- pread in recent years, partly due to their wide range of potential uses and also partly due to the fact that the technology enabling such networks is now widely available from many di?erent suppliers, such as: Crossbow, MoteIV, Intel and SUN (java based motes). These wireless sensor networks have the potential to allow a level of integration between computers and the physical world that, to date, has been virtually impos- ble. The uses for such networks is almost limitless and include such diverse app- cations as a counter sniper system for urban warfare [1] tracking the path of a forest re [2], determining the structural stability of a building after an earthquake [3], or tracking people or objects inside a building [4], etc.
