The Unified Modelling Language (UML) is a diagrammatic notation widely used in the computing industry and often taught in universities as a way to represent software requirements specifications and design descriptions. This paper identifies a number o problems associated with teaching UML and shows how to minimise their impact by making use of the Executable/Translatable UML (XTUML). tech news

This white paper describes the virtual office tools and technologies that are included with NetWare 6.5. Virtual Office provides Web mail, password management, company news, a personalized Web space along with Novell iFolder, iPrint and eGuide. Novell iFolder enables access to synchronized files from any location using a standard browser. iPrint enables secure printing to any printer over the Internet and eGuide provides a fast and efficient utility for end-user access to LDAP and eDirectory content such as employee lists, addresses, organization charts and more. Virtual Teams adds the ability to collaborate among multiple users with shared folders, Internet chat, a team calendar, team favorites and team discussions. tech news

An extensible infrastructure and a representation scheme for distributed smart virtual proxies of real world objects as presented in this paper could be a foundation to make the environment smart by enhancing simple objects with smart virtual counterparts. Design, implementation and deployment issues of concepts such as virtual counterparts (Virtual Objects), proximity (Virtual Location), meta objects (Virtual Meta Objects and Locations), lifecycle of virtual counterparts (Virtual Object Manager) and a queriable persistent Artifact Memory are discussed. tech news

Incorporate computing power into everyday objects in order to make them smart often fails due to physical limitations. Theres only so much room on a felt pen, for example, which might not make it possible to hold even a small scale computer and its battery. One viable solution is to link a real-world object to a virtual representation, for example a Web page, using an id that can be affixed to the object, such as a barcode label or an RFID tag. Once the artifact is brought into the vicinity of a reader, some sort of terminal device can then allow arbitrary storage and retrieval of information associated with this device. tech news
