Public Clouds
- Is There a Safe Harbor at all?
• Data is possibly at risk in public clouds
– Who owns your data?
• User authentication
– How safely are passwords stored?
• Data center location
– Is a data center in overseas really good for your
latency?

Are the developments in the HEFCE and JISC XCRI XML standards finally giving students the information they need to compare one university against the other? By standardising the output of content about courses, results and post graduation success in the job market, are students better positioned to evaluate the right University for them. This presentation will answer this question and discuss how universities can utilize Web Content Management to deliver on the demands of these standards and maximise student engagement.

The ROLE Requirements Bazaar

Dominik Renzel

In this Lightning Talk we want to present “Requirements Bazaar 2.0” that aims to be a social continuous innovation platform to bring developers and end-users together. In years of research we have developed and actually operated an open innovation platform for gathering requirements for prototypes in large international academic projects. The last version of the current product is available under http://requirements-bazaar.org . End-users can enter their requirements by providing short descriptions including user stories, screenshots and other images. The requirements can then be shared amongst its users. On the other side of the chain, developers may take up ideas and transfer the accepted requirements to an issue system like JIRA. Over the last years it turned out that people want more lightweight and mobile-friendly tools; we found the old monolithic system to be very hard to maintain to add new features. Therefore we are currently redeveloping it from scratch integrating many ideas from our users and incorporating new research findings. We are further driven by a mobile-first approach to support a wide variety of devices. We additionally want to support various social features like sharing on social networks or blogs and allowing discussions and rating amongst end-users and developers. At FOSDEM we would like to encourage open source developers in rethinking the way requirements are currently gathered from the crowd. How do we want to collect new software ideas or simply feature requests from our users. Will it really be through feedback forms in our apps’ “About” menu? Do our users really think in terms of issues like we developers do? How can gamification be used to reward actual end-users of software? We hope Requirements Bazaar can answer these questions and fill the gap!

Analysis of Overlapping Communities in Signed Complex Networks

Mohsen Shahriari

Web applications have overcome traditional desktop applications especially in collaborative settings. However, the bulk of Web applications still follow the "single user on a single device" computing model. Therefore, we created the DireWolf framework for rich Web applications with distributed user interfaces (DUIs) over a federation of heterogeneous commodity devices supporting modern Web browsers such as laptops, smart phones and tablet computers. The DUIs are based on widget technology coupled with cross-platform inter-widget communication and seamless session mobility. Inter-widget communication technologies connect the widgets and enable real-time collaborative applications as well as runtime migration in our framework. We show that the DireWolf framework facilitates the use case of collaborative semantic video annotation. For a single user it provides more flexible control over different parts of an application by enabling the simultaneous use of smart phones, tablets and computers. The work presented opens the way for creating distributed Web applications which can access device specific functionalities such as multi-touch, text input, etc. in a federated and usable manner.

DireWolf - Distributing and Migrating User Interfaces for Widget-based Web Ap...

Dejan Kovachev

Widget-based Web applications are outperforming monolithic Web applications in terms of distribution of the user interface on many devices and many standard browsers. However, latency of the remote inter-widget communication may be an obstacle for the uptake of Widget-based Web applications in near real-time domains like Web gaming and augmented reality. In this demo paper we show DireWolf 2.0 which is replacing the XMPP server of the DireWolf approach by a client-side relay realized by the means of WebRTC. This is not only decreasing the latency of the distributed interface for any application but also increasing the security by avoiding man-in-the-middle attacks on the XMPP server. This progress is enabling further uptake in Widget-based solutions in advanced Web engineering.
