IS Support for Web 2.0 Services – the Next StepsThe web is changing from being essentially a unidirectional publishing medium to one which supports multiparty content creation and collaboration – a change which provides both rich opportunities and challenges. The use of blogs, wikis, media-sharing services and other social software has been shown to empower both staff and students and to create exciting new learning opportunities. Examples include the use of blogs to allow students to share and reflect on learning, and to allow researchers to share knowledge, exchange ideas and easily publish work. Wikis provide a collaborative, easy to use content authoring tool for students, researchers and support staff. Social bookmarking services have introduced user defined tags, facilitating shared resource identification, while virtual worlds like Second Life have introduced new possibilities for social networking among distance students, and unique opportunities for the development of innovative pedagogies.
We have now had two reports on Web 2.0 in the University: an initial report which proposed one way forward, and a second report following an extensive consultation effort, which improved our understanding of user concerns in this area, as well as raising the profile of Web 2.0 in the user community. Our extensive preparatory work in this area is recognised as unique in a JISC report on Web 2.0 in learning and teaching. Now the IS Strategic Management Group has decided that Information Services should start implementing what’s been discussed. This paper makes the vision of what we’re trying to achieve more explicit, and outlines necessary steps towards its realization.

The current period has witnessed the increased use of web to a greater extent and the Web 2.0 has made the cyberspace as the global information space. Web 2.0 is a collection of technologies and services that allow increased user-creator interaction, content syndication, advancements in web-based user interfaces, which ultimately lead to the creation of an entirely new application platform.
Web applications are the most vulnerable elements of an organization’s IT infrastructure today. An increasing number of organizations (both for-profit and not-for-profit) depend on Internet-based applications that leverage the power of AJAX. As this group of technologies becomes more complex to allow the depth and functionality discussed, and, if organizations do not secure their web applications, then security risks will only increase. The most striking features of web 2.0 are its ability in harnessing collective intelligence and bringing rich users participation. The web 2.0 has rich applications with features such as user interaction, knowledge transfer and sharing and end user as well as source collaboration. The AJAX technology is used in many synchronous environments ranging from learning to many other purposes and their potential as well as implications are addressed in many studies.
The basic strength of the present web services environment is the Rich Internet Application is because of the deployment of JAVA script and DHTML for gaining interactivity in web pages. The fuse of many interrelated technologies has made the AJAX, (the AsynchronousOpen Source Physics: A User's Guide with ExamplesThe Open-Source Physics project is a synergy of curriculum development, computational physics, and physics education research. One goal of the project is to make a large number of Java simulations available for education using the GNU Open-Source model. This manual describes some of the classes and interfaces that are being used in this project.
Portions of Open Source Physics are being incorporated into the following:
• Java edition of An Introduction to Computer Simulation Methods by Harvey Gould, Jan Tobochnik, and Wolfgang Christian.
• Statistical and Thermal Physics project by Harvey Gould and Jan Tobochnik.
• Easy Java Simulations high-level modelling tool by Francisco Esquembre.
• Tracker video analysis program by Doug Brown.
Programmers wishing to adopt Open Source Physics tools for their own projects are encouraged to do so provided that these projects release their source code under the GNU Open-Source GPL license. Open Source Physics code is being distributed using CVS from the SourceForge web site:
http://sourceforge.net/projects/os-physics/
Additional curricula material and links are available from the Open Source Physics server hosted at Davidson College

These are often called “social software” or web2.0 tools. The research project links the use of freely available mobile friendly web2.0 tools accessed via a smartphone with the learning objectives of a variety of different tertiary education courses. The smartphone’s wireless connectivity and data gathering abilities (e.g. photoblogging, video recording, voice recording, and text input) allow for bridging the on and off campus learning contexts – facilitating “real world learning”.
The research is focusing on social constructivist approaches to education (Bijker et al., 1987; Lave & Wenger, 1991; Vygotsky, 1978; Wenger et al., 2002) and a conversational model (Laurillard, 2001, 2007) of teaching and learning. The disruptive nature of web2.0 and mobile technologies (Sharples, 2000, 2001, 2005; Stead, 2006) facilitates a move from instructivist pedagogies to social constructivist pedagogies.
The personal, social networking, and context awareness of mobile devices democratise power relationships and are best suited to open learning environments. Disruptive technologies are those technologies that challenge established systems and thinking, requiring change and are thus viewed by many as a threat to the status quo. Disruptive technologies democratise institutional learning environments challenging the established power relations between teachers and students.

You will also setup a character inside the environment and to add interactivity in Virtools. This tutorial introduces you to Maya’s 3D Paint Effects allowing you to paint in 3D. A few strokes can paint trees, grass, flowers. The paint strokes from your brush are converted into 3D objects inside a 3D space. Maya’s ability to convert 3D Paint Effects to polygonal objects is helpful to create content for interactive environments. This tutorial requires Maya 5.0 and up.
You can control the strokes’ shape, color, density, while painting on the horizontal grid plane of the perspective view or directly on other 3D objects. Let’s grab a brush and start to paint trees and grass in 3D, let’s create the ground for your forest.
3.1 - Creating the ground
Open a new scene in Maya. Go to the top menu, select, “File” > “New Scene”. Select the “Modeling” module in the box located on the left of the “Status Line”. Create a polygonal plane for the floor of your scene. Go to, “Create” > “Polygon Primitives” > “Plane”

Mandriva Linux 2007 product range Mandriva Linux: Web 2.0 ready! Mandriva Linux Services Mandriva Linux 2007 Services Glossary In 1983, Richard Stallman founded the GNU Project, with the goal of developing a complete Unix-like operating system composed entirely of free software. By the beginning of the 1990s, GNU had produced or collected most of the necessary components of this system except for the core component, the kernel. In 1991, the Linux kernel was created as a hobby by Finnish university student Linus Torvalds.
A typical general-purpose distribution includes: . the Linux kernel, . some GNU libraries and tools, . command-line shells, . the graphical X Window ® system, . and an accompanying desktop environment such as KDE or GNOME, . several applications for office, multimedia, development or server needs.

• MySQL is an SQL based relational database management system that runs on more than 20 platforms including Windows, Linux, OS/X, HP-UX and many more.
• The owner and producer of MySQL is a Swedish company called MySQL AB. They provide services and training programs for MySQL users. The software’s official website http://www.mysql.com gives the latest information about the company and MySQL.
• MySQL is declared the world’s most popular open source database by its founders: “It's used in more than 6 million installations ranging from large corporations to specialized embedded applications on every continent in the world. (Yes, even Antarctica!).” www.mysql.com
• The reasons for its popularity are: It is free and open source! Users can download the code for free and modify it according to their needs.
Its consistent fast performance. Speed is crucial in database driven applications since the time it takes for the user to see the result of a query is the main performance measure for the application.
High reliability. Every release of MySQL is heavily tested by users and developers all over the world since it is free of charge and open source. Ease of use. The main interaction with the MySQL server is through SQL commands which are easy to master!
It is supported by PHP (more on this later).
• A brief history of the software, its name and its logo from its founders at http://dev.mysql.com: “We started out with the intention of using mSQL to connect to our tables using our own fast low-level (ISAM) routines.ActionScript 3.0 Class Diagram Sample PDFWelcome to ActionScript 3.0, the new ECMA Error classes based language from Adobe Systems.
