Linux by Knight Post 43 Pentagon's Zombie Satellite Program Comes to Life




From:  http://www.wired.com

The Pentagon’s intergalactic black-magic plot 
is getting ready to raise the dead.

Dead satellites, that is. Last year, Darpa, the military’s blue-sky research agency, kicked off a program designed to harvest parts from unused communications satellites still orbiting the Earth, and then turn those bits and pieces — antennas in particular — into an array that operates as a low-cost “communications farm” for troops on the ground

Linux by Knight Post 042 Twisted Light Wifi Creates Connectivity Fast Lane 2,4 Terabit Per Second





From:  http://www.forextv.com

The internet is about to get the equivalent of an express lane as a result of new wireless technology developed by American and Israeli scientists.  High-speed wireless transmission of up to 2.5 terabits per second may be possible by what is being called "twisted, vortex beams."  It is essentially a new wifi protocol that uses light beams more efficiently that what is currently in use.

Linux by Knight Post 045 Flame's Crypto Attack May have Needed $200,000 Worth of Compute Power




A cluster of 200 PlayStation 3 consoles used in 2008 to find a cryptographic collision in the MD5 algorithm.






From:  http://arstechnica.com





The cryptographic attack that Flame engineers used to hijack Microsoft's Windows Update process was so computationally demanding, it would have required the equivalent of $200,000 worth of computing time from Amazon's EC2 Web service for most people to carry it out.
