Submission + - Report: Facebook, Skype Getting Really Friendly (crn.com)

cgriffin21 writes: Facebook and Skype are reportedly in talks over a deal that would integrate Skype calling capabilities into Facebook user accounts. Such an agreement would give both Skype and Facebook not only a leg up on rival VoIP and social networking services from the likes of Google, but also the combined force of two Internet-based services beloved by consumers. The talks, which were reported by All Things Digital Wednesday, stems from Facebook's goal of merging IP communications and social networking communities more closely together. Facebook in recent weeks had also been rumored to be developing a mobile device of its own.

Submission + - German Military Braces for Peak Oil (nytimes.com)

myrdos2 writes: A study by a German military think tank leaked to the Internet warns of the potential for a dire global economic crisis in as little as 15 years as a result of a peak and an irreversible decline in world oil supplies. The study states that there is "some probability that peak oil will occur around the year 2010 and that the impact on security is expected to be felt 15 to 30 years later. ... In the medium term the global economic system and every market-oriented national economy would collapse". The report closely matches one from the US military earlier this year, which stated that surplus oil production capacity could disappear within two years and there could be serious shortages by 2015 with a significant economic and political impact.

Submission + - Nanoresonators create ultra-high-res displays (linuxfordevices.com)

TuurlijkNiet writes: Eat your heart out, 'Retina display'. A new technology unveiled yesterday will allow creating pixels eight times smaller than the ones on Apple's iPhone 4, eliminate the need for polarizer layers, and allow screens to make much more efficient use of available light, say University of Michigan researchers. The pixels in the nanoresonator displays are about ten times smaller than those on a typical computer screen, and about eight times smaller than the pixels on the iPhone 4, which are about 78 microns, according to Guo. Such pixel densities could make the technology useful in projection displays, as well as wearable, bendable or extremely compact displays, according to the researchers.
