Submission + - ZFS Replication to the Cloud is Finally Here ... and it's Fast (arstechnica.com)

kozubik writes: Jim Salter at arstechnica provides a detailed, technical rundown of ZFS send and receive and compares it to traditional remote syncing and backup tools such as rsync. He writes: "In mid-August, the first commercially available ZFS cloud replication target became available at rsync.net. Who cares, right? As the service itself states, If you're not sure what this means, our product is Not For You. ... after 15 years of daily use, I knew exactly what rsync's weaknesses were, and I targeted them ruthlessly."

Submission + - Hackers have infiltrated our power grid's control networks (lasvegassun.com)

davidwr writes: A security researcher and the Associated Press are reporting that hackers have infiltrated many of our nation's power grid networks. Exfiltrated data included engineering plans and other non-public information that could aid an attacker later as well as account credentials. Multiple companies were affected but one of the more notable ones was the energy provider Calpine.

Submission + - Meet the Scientist Who Injected Himself with 3.5 Million-Year-Old Bacteria (vice.com)

Press2ToContinue writes: Anatoli Brouchkov is a soft-spoken guy with silver hair, and when he lets out a reserved chuckle, his eyes light up like he was belly laughing. If you met him on the street, you’d never guess that he once injected himself with a 3.5 million-year-old strain of bacteria, just to see what would happen.

According to Brouchkov, Bacillus F has a mechanism that has enabled it to survive for so long beneath the ice, and that the same mechanism could be used to extend human life, too—perhaps, one day, forever. In tests, Brouchkov says the bacteria allowed female mice to reproduce at ages far older than typical mice. Fruit flies, he told the Siberian Times, also experienced a “positive impact” from exposure to the bacteria.

Submission + - Ask slashdot - Alternatives to aging hardware RAID 5 setup

digitalmischief writes: I currently have a server which has a hardware raid card (Areca 1220) with 7x2TB drives in it and hot spare. It works perfectly well but on adding a new disk to the array was very slow (2+ days!)

I feel the solution is getting a bit long in the tooth and its not really a good idea to have raid 5 which such big disks. I also worry that my card is getting old and I'm starting to worry about the whole setup in terms of reliability — I have a full backup system in place (another server)

I have been looking at zFS which seems like a better solution, possibly RaidZ2 but want to hear of any other recommendations?

Also how would zfs performance compare?

thanks!

Submission + - Facebook bans KDE application, deletes user photos (networkworld.com)

lazyeye writes: "Hopefully this is just an honest error on Facebook's part, but many people who use KDE's kipi-plugins to upload pictures to Facebook have been unable to upload pictures as of June 27, 2011. What's worse is that pictures that were once uploaded using these plugins have now been deleted from people's Facebook photo pages. The digiKam page on Facebook is abuzz and users have been trying to get the word out. Joe "Zonker" Brockmeier has also taken notice and has written the following blog post exposing the issue."

Submission + - Massive US spy operation on Arab world uncovered (scmagazine.com.au)

mask.of.sanity writes: Get comfortable. This is huge — in gravity and length. A crowd sourced investigation dubbed Project PM has probed reams leaked emails involving US intelligence companies and uncovered a massive spy operation targeting social media and telecommunications in the Arab world. The allegations, derived from 70,000 emails stolen from HBGary earlier this year, detailed a project dubbed Romas/COIN, to be proceeded by Odyssey, which could automatically analyse millions of conversations. Google, Apple, the trio of HBGary spooks and even Disney are involved.

Submission + - World's first Content Addressable Memory (CAM) (techspot.com)

AlienIntelligence writes: NEC announces new memory type and with it we hopefully move closer to "instant-on" devices that will have memory state saved or suspended without the drain on battery life.

FTA, so you don't have to be bothered to clicky clicky:
http://www.techspot.com/news/44250-nec-develops-memory-that-stores-data-without-using-power.html

NEC touts two key features of the new technology: the CAM is nonvolatile while maintaining a high speed, and it uses approximately half the circuit area in comparison to existing technologies. The new CAM is a part of spintronics logic integrated circuit technologies that utilize the negative properties of electrons together with the spin magnetic moment. It leverages the vertical magnetization of vertical domain wall elements in reaction to magnetic substances in order to enable data that is processing within the CAM to be stored on a circuit without using power.

If that jargon really messed with your head, here's what you have to remember: data can be saved on circuits even when power is cut from the CAM.

Submission + - Mine BitCoin get busted for pot farming (computerworld.com)

c0lo writes: Among other risks caused by the low understanding of police and gub agencies on what BitCoin is, the high amount of electricity needed to create a single bitcoin bills can lead to marijuana busts.

The Canadian town of Mission, BC has a bylaw that allows the town's Public Safety Inspection Team to search people's homes for grow ops if they are using more than 93 kWh of electricity per day. There have allegedly been reports floating in IRC of two different cases of police showing up at a bitcoin miner's residence with a search warrant.

Ohio police and the DEA file at least 60 subpoenas each month for energy-use records of people suspected of running an indoor pot growing operation. DEA Agent Anthony Marotta said high electricity usage does not always mean the residence is an indoor pot farm and has surprised federal agents. "We thought it was a major grow operation ... but this guy had some kind of business involving computers. I don't know how many computer servers we found in his home."

America's Army Games Cost $33 Million Over 10 Years 192

Responding to a Freedom Of Information Act request, the US government has revealed the operating costs of the America's Army game series over the past decade. The total bill comes to $32.8 million, with yearly costs varying from $1.3 million to $5.6 million. "While operating America's Army 3 does involve ongoing expenses, paying the game's original development team isn't one of them. Days after the game launched in June, representatives with the Army confirmed that ties were severed with the Emeryville, California-based team behind the project, and future development efforts were being consolidated at the America's Army program office at Redstone Arsenal in Alabama. A decade after its initial foray into the world of gaming, the Army doesn't appear to be withdrawing from the industry anytime soon. In denying other aspects of the FOIA request, the Army stated 'disclosure of this information is likely to cause substantial harm to the Department of the Army's competitive position in the gaming industry.'"
