Submission + - BitCoin price crashes (mtgox.com) 1

An anonymous reader writes: The exchange rate for Bitcoins has crashed after an account with over 500,000 Bitcoins on the popular Bitcoin exchange, MtGox, was compromised. The transactions from the compromised account caused the price to drop from US$17 to $0.01 in less than an hour.

A database dump of the usernames and passwords of MtGox accounts was also obtained.

Submission + - MtGox.com Bitcoin trading site compromised (mtgox.com) 3

Beardydog writes: Bitcoin trading site MtGox.com has suspended operations for the rest of the day after illicit access to at least one account resulted in a steep drop in the price of Bitcoins on the site. Commenters to the support page for the event are reporting that a list of usernames and associated email addresses and password hashes have been posted online. MtGox are currently planning to roll back all of the day's trading, email notices to all affected users, and require replacement passwords for affected accounts.

Comment Re:It is not about Fukushima. It is the waste. (Score 1) 822

Fukushima is just an example that a complex technology like nuclear power can fail, even with a lot of safeguards in place and in a high-tech country like Japan.

...and how do you safeguard against incompetence, greed, and other undesirable features of human nature? Nuclear systems and their waste require constant care and diligence to prevent catastrophes. Most other power generation systems will simply shut down, and at worst the damage will be very localized, when there is a fault, design flaw, or neglect.

Comment How creative are you? (Score 1) 562

My wife and I talked about emergency preparedness the other day. She wanted to buy a kit from Costco, and I pointed out that with a little creativity we already have a lot of what we need.

Water: first off, our R.O. unit has a 2 gallon tank. Each of our toilets has 1.6 gallons in the tank. We have a propane BBQ and at least one tank of propane on hand so we could start boiling water the stored water runs out. If the muni water system isn't delivering anything at all, there's a creek nearby. And we have a ceramic purifier filter (for backpacking) that we could use in a pinch.

Food: At any given time there's at least 2 weeks' worth of dry and canned goods in our pantry. We shop at Costco and naturally stock up.

Shelter / warmth: We have a couple of tents, tarps, sleeping bags, and lots of blankets and sheets.

First aid: We already have a first aid kit.

Communications: We have a hand-crank radio, and a solar battery / cell phone charger.

Defence: In my mind, the most important item after water. We have weapons and ammunition.

Comment Open source is a good thing all around (Score 4, Insightful) 231

I'm encouraged to hear that major organizations are finally seeing the light.

To use a (yet another, sorry) car analogy: Open source is like being able to buy a service manual and replacement parts at your local auto shop, and then doing the work yourself -- or paying a mechanic of your choice to do it for you. Closed source is more like buying the car with the hood welded shut, and any attempt to modify or service it yourself not only voids the warranty, but is actually criminal in some situations and jurisdictions. Moreover, the manufacturer is under no obligation to disclose or repair defects or "undocumented features" -- such as logging your travels and selling it to the highest bidder.

Survey Shows That Fox News Makes You Less Informed 1352

A survey of American voters by World Public Opinion shows that Fox News viewers are significantly more misinformed than consumers of news from other sources. One of the most interesting questions was about President Obama's birthplace. 63 percent of Fox viewers believe Obama was not born in the US (or that it is unclear). In 2003 a similar study about the Iraq war showed that Fox viewers were once again less knowledgeable on the subject than average. Let the flame war begin!

Red Hat Settles Patent Case 76

darthcamaro writes "Red Hat has settled another patent case with patent holding firm Acacia. This time the patent is US Patent #6,163,776, 'System and method for exchanging data and commands between an object oriented system and relational system.' While it's great that Red Hat has ended this particular patent threat, it's not yet clear how they've settled this case. The last time Red Hat tangled with Acacia they won in an Texas jury trial. 'Red Hat routinely addresses attempts to impede the innovative forces of open source via allegations of patent infringement,' Red Hat said in a statement. 'We can confirm that Red Hat, Inc and Software Tree LLC have settled patent litigation that was pending in federal court in the Eastern District of Texas.'"

Decades-Old Soviet Reflector Spotted On the Moon 147

cremeglace writes "No one had seen a laser reflector that Soviet scientists had left on the moon almost 40 years ago, despite years of searching. Turns out searchers had been looking kilometers in the wrong direction. On 22 April, a team of physicists finally saw an incredibly faint flash from the reflector, which was ferried across the lunar surface by the Lunokhod 1 rover. The find comes thanks to NASA's Lunar Reconnaissance Orbiter, which last month imaged a large area where the rover was reported to have been left. Then the researchers, led by Tom Murphy of the University of California, San Diego, could search one football-field-size area at a time until they got a reflection."

Creating Electric Power From Light Using Gold Nanoparticles 77

cyberfringe writes "Professor of Materials Science Dawn Bonnell and colleagues at the University of Pennsylvania have discovered a way to turn optical radiation into electrical current that could lead to self-powering molecular circuits and efficient data storage. They create surface plasmons that ride the surface of gold nanoparticles on a glass substrate. Surface plasmons were found to increase the efficiency of current production by a factor of four to 20, and with many independent parameters to optimize, enhancement factors could reach into the thousands. 'If the efficiency of the system could be scaled up without any additional, unforeseen limitations, we could conceivably manufacture a 1A, 1V sample the diameter of a human hair and an inch long,' Prof. Bonnell explained. The academic paper was published in the current issue of ACS Nano. (Abstract available for free.) The significance? This may allow the creation of nano-sized circuits that can power themselves through sunlight (or another directed light source). Delivery of power to nanodevices is one of the big challenges in the field."
