Navizon is a software-only wireless positioning system that triangulates signals broadcasted from Wi-Fi access points and Cellular towers to help the users find their way in most major metropolitan areas worldwide. The Navizon network is based on a collaborative database. Members with a GPS device can use Navizon to map the Wi-Fi and cellular landscape in their neighborhoods. Once they synchronize their data, it is made available to all the other users of the network. This way, users who don't have a GPS device can benefit from a positioning system. And it's free for personal use.

The power of collaborative effort, especially relevant to us Pittsburghers. People can report on the road and snow conditions on streets close to where they live.

Providing fair assessment with timely feedback for students is a difficult task with science laboratory classes containing large numbers of students. Such classes are usually assessed by short-answer questions (SAQs) centred on principles encountered in the laboratory. It has been shown recently that computer-assisted assessment (CAA) has several advantages and is well received by students. However, student evaluation has shown that this system does not provide suitable feedback. Thus, the authors introduced peer assessment (PA) as a complementary procedure. In October 2006, 457 students registered for a first-year practical unit in the Faculty of Life Sciences, University of Manchester. This unit consists of ten compulsory biology practical classes. The first four practicals were assessed using PA; the remaining six practicals were assessed by CAA and marked by staff or postgraduate student demonstrators. The reliability and validity of PA were determined by comparing duplicate scripts and by staff moderation of selected scripts. Student opinions were sought via questionnaires. The authors show that both assessments are valid, reliable, easy to administer and are accepted by students. PA increases direct feedback to students, although the initial concerns of student groups such as mature and EU/International students need to be addressed using pre-PA training.

EtherPad is the only web-based word processor that allows people to work together in really real-time. When multiple people edit the same document simultaneously, any changes are instantly reflected on everyone's screen. The result is a new and productive way to collaborate on text documents, useful for meeting notes, drafting sessions, education, team programming, and more.
