Submission + - Visa offers "virtual" credit cards - no pl (apcmag.com)

BaconFloss writes: "Credit giant Visa has unveiled a new super-secure credit card for online shopping: it's merely a card number and expiry date on a piece of paper which expires once you've used up the prepaid amount. There's no plastic involved. It works much like a mobile phone prepaid recharge voucher, except that the virtual card number is printed out on the docket. Clearly it's relatively secure compared to a rolling credit account, but is it also a tacit admission that the card companies have failed to actually make credit cards adequately secure in the high fraud environment we live in today?"

Submission + - How To: Arm a nuclear bomb with a Bic pen (bbc.co.uk)

rubydooby writes: Well, until 1998. According to the BBC, Britain's WE 177 nuclear bomb's final layer of protection was a familiar-looking cylindrical key. That's right, it's the same type as the key to the recently-replaced Kryptonite bicycle lock- brought to fame by demonstrations of it's compatibility with Bic pen barrels. Other security features? How about "a series of dials which you can turn with an Allen key to select high yield or low yield, air burst or groundburst and other parameters". Everyone knows how hard it is to find the right size allen wrench... All this is in contradistinction to the U.S.'s "PAL protection", or "Permissive Action Links", which required the Chiefs of Staff to phone in the correct combination. Of course, the U.K. government responds that "officers of the Royal Navy as the Senior Service could be trusted", (BBC) and that The Bombs are "designed such that the warhead must have experienced missile launch and ballistic deployment before it can detonate". Now I feel safe.

Submission + - British nukes were protected by bike locks (bbc.co.uk)

mattaw writes: From an article in the BBC's Newsnight program: Until 1998 the RAF nuclear bomb was protected by a bike lock.

After the Americans implemented coded arming systems their was an attempt to get these fitted to the British systems however this was rejected by the Navy with the following statement:

"It would be invidious to suggest... that Senior Service officers may, in difficult circumstances, act in defiance of their clear orders".

That's alright then.

Submission + - Major Breakthrough in Speech Brain Hack

jd writes: "In a major breakthrough, neurologists are reporting that they can decypher neurological impulses into speech with an 80% accuracy. A paralyzed man who is incapable of speech has electrodes implanted in his brain which detect the electrical pulses in the brain relating to speech. These signals are then fed into computers which covert these pulses into signals suitable for speech synthesis. As a biotech marvel, this is astonishing. Depending on the rate of development it is possible to imagine Professor Hawking migrating to this, as it would be immune to any further loss of body movement and would vastly accelerate his ability to talk. On the flip-side, direct brain I/O is also a major step towards William Gibson's Neuromancer and other cyberpunk dark futures."
It's funny.  Laugh.

Submission + - Oddly, Hypocrisy Rooted in High Morals (yahoo.com)

caffiend666 writes: "According to a Live Science article: "Actually, a new study finds that a sense of moral superiority can lead to unethical acts, such as cheating. In fact, some of the best do-gooders can become the worst cheats.... In the new study, detailed in the November issue of the Journal of Applied Psychology, researchers find that when this line between right and wrong is ambiguous among people who think of themselves as having high moral standards, the do-gooders can become the worst of cheaters.... The researchers suggest an "ethical person" could view cheating as an OK thing to do, justifying the act as a means to a moral end." All righty then...."

Submission + - Meet the drivers behind NASA's Mars Rovers (idg.com.au)

StonyandCher writes: "Scott Maxwell must have one of the best IT jobs in the solar system, driving NASA's Mars Rovers. Behind every robot is a driver. He's one of 14 Rover Drivers that work in NASA's California-based Jet Propulsion Laboratory. He tells you what it is like to control a robot on another planet. Maxwell discusses what makes up an average work day, the highlights of the project, how he got the job, and the tools he uses in his work. A great look at the team of dedicated IT workers behind the robots, plotting the every move of NASA's twin robot geologists, Spirit and Opportunity, since they first landed on Mars at the start of 2004,"

A New Theory of Everything? 511

goatherder writes "The Telegraph is running a story about a new Unified Theory of Physics. Garrett Lisi has presented a paper called "An Exceptionally Simple Theory of Everything" which unifies the Standard Model with gravity — without using string theory. The trick was to use E8 geometry which you may remember from an earlier Slashdot article. Lisi's theory predicts 20 new particles which he hopes might turn up in the Large Hadron Collider."

It's a naive, domestic operating system without any breeding, but I think you'll be amused by its presumption.
