nodialtone writes with a Reuters report that Rod Beckstrom, director of the National Cybersecurity Center (NCSC), has tendered his resignation, citing clashes between the NCSC and the NSA with regard to who handles the nation's online security efforts. In his resignation letter (PDF), he made the point that "The intelligence culture is very different than a network operations or security culture," and said he wasn't willing to "subjugate the NCSC underneath the NSA." He also complained of budget roadblocks which kept the NCSC from receiving more than five weeks of funding in the past year. Wired has a related story from late February which discusses comments from Admiral Dennis Blair, director of National Intelligence, who thinks cyber security should be the NSA's job to begin with.

'The remote heating of condensation nuclei could be achieved by applying electromagnetic radiation, such as microwaves,' says Cranfield University's Frank Noppel. 'Depending on assumptions made, calculation shows that the power required for such a device could be as little as 0.1% of the engine power.'"
