1 Ruby is an open source programming language that was released in 1995. th 2 Ruby is ranked 10 in the TIOBE Programming Community index . Ruby 3 on Rails is an open source web framework that was released in 2004. Ruby on Rails is being widely adopted because of its simplicity, 4 maintainability and development speed. Computerworld lists Ruby on Rails as the one of the top 5 technologies for 2007. Motivation for this Book Ruby is often compared with PHP, which is the most commonly used scripting language, and with Java, which is the most commonly used programming language. In the trends graph...

Although a number of cryptography and security techniques have been around for quite some time, emerging technologies, such as ubiquitous computing and ambient intelligence that exploit increasingly interconnected networks, mobility and personalization, put new requirements on privacy and security with respect to data management. As data are accessible anytime anywhere, according to these new concepts, it becomes much easier to get unauthorized data access. As another consequence, the use of new technologies has brought some privacy concerns. It becomes simpler to collect, store, and search...

Estonia, China, Korea, Spain, Taiwan and the USA contributed 2 papers each and Canada, Germany, Greece, Poland, Turkeyand Vietnam contributed 1 paper each. We would liketo thank all of the authors who submitted papers to...

Asynchronous JavaScript and XML (Ajax) is a web technique used to transfer data between a browser and server asynchronously without posting the web page to the server. "Asynchronously" implies that the processing of the web page continues while the Ajax request is sent to the server and a response is received from the server. The web page, or section(s) of the web page, is refreshed with the Ajax response without reposting the web page. Ajax has the following advantages over non-Ajax web applications.

- Reduced response time and reduced server load, as the complete web page...

With the growingubiquity of computing systems it is essentialthat we canplace reliance on the services they deliver. This is particularly obvious and important in areas like aircraft avionics, global ?nancial transaction processing, or nuclear power plant control where human lives or large ?nancial values are at stake. But also the worldwide daily nuisances of computer viruses or data corruptions caused by crashing operating systems collectively impose high costs on society, which are beginning to become economically relevant. Within computer science, the termdependability has been introduced...

This volume contains the papers presented at the 11th International Conference on Theory and Applications of Satis?ability Testing (SAT 2008). The series of International Conferences on Theory and Applications of S- is?ability Testing (SAT) has evolved from a ?rst workshop on SAT in 1996 to an annual international conference which is a platform for researchers studying various aspects of the propositional satis?ability problem and its applications. In the past, the SAT conference venue alternated between Europe and North America. For the ?rst time, the conference venue was in Asia, more...

This year, the IFIP Working Conference on Distributed and Parallel Embedded Sys tems (DIPES 2008) is held as part of the IFIP World Computer Congress, held in Milan on September 7 10, 2008. The embedded systems world has a great deal of experience with parallel and distributed computing. Many embedded computing systems require the high performance that can be delivered by parallel computing. Parallel and distributed computing are often the only ways to deliver adequate real time performance at low power levels. This year's conference attracted 30 submissions, of which 21 were accepted. Prof....

Thoroughly revised for a one-semester course, this well-known and highly regarded book is an outstanding text for undergraduate discrete mathematics. It has been updated with new or extended discussions of order notation, generating functions, chaos, aspects of statistics, and computational biology. Written in a lively, clear style that talks to the reader, the book is unique for its emphasis on algorithmics and the inductive and recursive paradigms as central mathematical themes. It includes a broad variety of applications, not just to mathematics and computer science, but to natural and...

Active Directory is the new directory service for Windows 2000. Basically, it will be a network service that identifies all resources on a network and makes them accessible to users and applications. This was not found in previous versions of NT, and administrators will have to learn a completely new way of managing their directories. This is the feature of Windows 2000 that administrators are looking forward to using. This book should help them with the day-to-day tasks, and assist in managing their networks.
