Submission + - The Hysteria of the Cyber-Warriors (bostonreview.net)

Willfro writes: Evgeney Morozov has a piece up now at Boston Review about the hyperbole and reality of "cyber war".

"At the end of May, President Obama called cyber-security 'one of the most serious economic and national security challenges we face as a nation.' His words echo a flurry of gloomy think-tank reports. Unfortunately, these reports are usually richer in vivid metaphor--with fears of "digital Pearl Harbors" and "cyber-Katrinas"--than in factual foundation.

So why is there so much concern about "cyber-terrorism"? Answering a question with a question: who frames the debate? Much of the data are gathered by ultra-secretive government agencies--which need to justify their own existence--and cyber-security companies--which derive commercial benefits from popular anxiety. Journalists do not help. Gloomy scenarios and speculations about cyber-Armaggedon draw attention, even if they are relatively short on facts.

This is the first time that the new EXT4 and Btrfs and NILFS2 filesystems have been directly compared when it comes to their disk performance though the results may surprise. For the most part, EXT4 came out on top.

Dotnaught writes: "Sony is now shipping computers in China with Green Dam installed, in advance of the Chinese government's July 1 deadline. But the company is disclaiming responsibility for any damage caused by the Web filtering software. Documents posted by Hong Kong-based media studies professor Rebecca MacKinnon also suggest that the Chinese government is considering similar filtering requirements for mobile phones."

Submission + - Spirit Rover Begins Making Night Sky Observations (universetoday.com)

Nancy Atkinson writes: "Even though the Spirit rover is stuck in loose soil on Mars, she has an overabundance of electrical power due to a wind event that cleaned off her solar panels. While MER scientists and engineers are having the rover take pictures of her surroundings in an effort to figure a way to get her dislodged, there also is enough power (since the rover isn't moving anywhere) to do something extra: keep the rover "awake" at night and run her heaters so she can take images of the night sky on Mars. "Certainly, a month or more ago, no one was considering astronomy with the rovers," said Mark Lemmon, planetary scientist at Texas A&M University and member of the rover team. "We thought that was done. With the dust cleanings, though, everyone thinks it is better to use the new found energy on night time science than to just burn it with heaters.""
