The biggest factor in a company's decision to go with Linux is overcoming thesupport issues. Adopting Linux successfully means taking on a differentapproach to support. Since Linux is open source, there are different methodsto get the support that companies need. This includes deeper skills on how toinvestigate problems, how to get help from the open source community (i.e.how to ask for help on usenet) and how to resolve problems in-house withoutthe extra cost of a consultant. This book should be an essential part of everycompany's Linux adoption plan to keep the total cost of ownership (TCO)down and improve the ROI of their Linux strategy. It is also a book thatadvanced Linux professionals running their own Linux systems will be able touse to troubleshoot. This book gives the staff the basics they need to diagnose most problems that they will face and will go into the nitty-gritty on the toughest problems. It also points users to the appropriate resources so that they may get help quickly.

Here is the ultimate guide to creating and extending documents within the application programming interface of the Document Object Model (DOM). The book examines real-world applications of the DOM, including exclusive case studies of DOM-based browsers and applications and provides a comprehensive, language-neutral examination of the DOM and its related applications.

While computational technologies are transforming the professional practice of mathematics, as yet they have had little impact on school mathematics. This pioneering text develops a theorized analysis of why this is and what can be done to address it. It examines the particular case of symbolic calculators (equipped with computer algebra systems) in secondary education. Drawing on a substantial program of French innovation and research, as well as closely related studies from Australia and the Netherlands, it provides rich illustrations of the many aspects of technology integration, and of the ways in which these are shaped at different levels of the educational institution. This pioneering text develops a theorized analysis of why this is and what can be done to address it.

Current IT developments like component-based development and Web services have emerged as effective ways of building complex enterprise-scale information systems and providing enterprise application integration. To aid this process, platforms such as .NET and WebSphere have become standards in web-based systems development. However, there are still a lot of issues that need to be addressed before service-oriented software engineering (SOSE) becomes a prominent and widely accepted paradigm for enterprise information systems development and integration. Service-Oriented Software System Engineering: Challenges and Practices provides a comprehensive view of SOSE through a number of different perspectives. Some of those perspectives include: service-based concepts, modeling and documentation, service discovery and composition, service-oriented architecture, model-driven development of service-oriented applications, service security and service-orientation in mobile settings. It provides readers with an in-depth knowledge of the main challenges and practices in the exciting, new world of service-oriented software engineering. Addressing both technical and organizational aspects of this new field, this book offers a balance making it valuable to a variety of readers, including IT architects, developers, managers, and analysts.
