Wireless Power Demonstrated 124

Necroloth and other readers sent in the story of Witricity's latest demo at the TED Global conference in Oxford, UK. The company is developing a system that can deliver power to devices without the need for wires. The idea is not new — electrical pioneers Thomas Edison and Nicola Tesla assumed that power would be delivered wirelessly. The BBC quotes the inventor behind Witricity's tech as saying that Tesla and Edison "...couldn't imagine dragging this vast infrastructure of metallic wires across every continent." eWeek Europe notes some hurdles the technology must overcome: "The 2007 experiment it is based on had an efficiency of only around 45 percent, but [Witricity's CEO] promised power delivered wirelessly would start out 15 percent more expensive than wires, and improve on that." Intel has also demonstrated wireless charging.

East Africa Gets High-Speed Internet Access Via Undersea Cable 198

Abel Mebratu writes with this excerpt from the BBC: "The first undersea cable to bring high-speed internet access to East Africa has gone live. The fiber-optic cable, operated by African-owned firm Seacom, connects South Africa, Tanzania, Kenya, Uganda and Mozambique to Europe and Asia. The firm says the cable will help to boost the prospects of the region's industry and commerce. The cable — which is 17,000km long — took two years to lay and cost more than $650m."

Submission + - Ibis 2.0 released (cs.vu.nl)

rvannieuwpoort writes: "Ibis 2.0 is available now! Ibis is a Java communication library which was specifically designed for use in a grid environment. Ibis provides a rich set of communication primitives, such as point-to-point, broadcast, many-to-one, etc. Also, it has a high-performance serialization implementation, which can be up to ten times faster than standard serialization. Ibis 2.0 now has support for our novel Smartsockets library, and is able to work in harsh networking environments with firewalls, NATs, etc. transparently. During Supercomputing'07 we are giving live demos at the Dutch booth (nr. 2409). For more info, see http://www.cs.vu.nl/ibis."
