Why the First Cowboy To Draw Always Gets Shot 398

Posted by timothy from the more-guns-less-crime dept.
cremeglace writes "Have you ever noticed that the first cowboy to draw his gun in a Hollywood Western is invariably the one to get shot? Nobel-winning physicist Niels Bohr did, once arranging mock duels to test the validity of this cinematic curiosity. Researchers have now confirmed that people indeed move faster if they are reacting, rather than acting first."

PS3 Hacked? 296

Posted by Soulskill from the another-one-bites-the-dust dept.
Several readers have sent word that George Hotz (a.k.a. geohot), the hacker best known for unlocking Apple's iPhone, says he has now hacked the PlayStation 3. From his blog post: "I have read/write access to the entire system memory, and HV level access to the processor. In other words, I have hacked the PS3. The rest is just software. And reversing. I have a lot of reversing ahead of me, as I now have dumps of LV0 and LV1. I've also dumped the NAND without removing it or a modchip. 3 years, 2 months, 11 days...that's a pretty secure system. ... As far as the exploit goes, I'm not revealing it yet. The theory isn't really patchable, but they can make implementations much harder. Also, for obvious reasons I can't post dumps. I'm hoping to find the decryption keys and post them, but they may be embedded in hardware. Hopefully keys are setup like the iPhone's KBAG."

Heat Engines Shrunk By Seven Orders of Magnitude 168

Posted by kdawson from the gimme-a-v8-of-those dept.
KentuckyFC writes "The vast majority of motors that power our planes, trains, and automobiles are heat engines. They rely on the rapid expansion of gas as it heats up to generate movement. But attempts to shrink them by any significant amount have mostly ended in failure. Today, the smallest heat engines have a volume of some 10^7 cubic micrometers. Now group of Dutch engineers has built a heat engine that is seven orders of magnitude smaller than this. The engine consists of a piezoelectric bar that expands and contracts in the normal piezoelectric way. However it also heats up and cools at the same time causing a thermal expansion and contraction, which lags the piezoelectric displacement. By carefully choosing the frequency of the driving AC current, the Dutch team found a resonant effect in which the thermal expansion and contraction amplifies the mechanical motion, making it a true heat engine. Operating the thermodynamic cycle in reverse turns the device into a heat pump or refrigerator. The total volume of the device is just 0.5 cubic micrometres."

Facebook Master Password Was "Chuck Norris" 319

Posted by samzenpus from the ad-nauseum-roundhouse dept.
I Don't Believe in Imaginary Property writes "A Facebook employee has given a tell-all interview with some very interesting things about Facebook's internals. Especially interesting are all the things relating to Facebook privacy. Basically, you don't have any. Nearly everything you've ever done on the site is recorded into a database. While they fire employees for snooping, more than a few have done it. There's an internal system to let them log into anyone's profile, though they have to be able to defend their reason for doing so. And they used to have a master password that could log into any Facebook profile: 'Chuck Norris.' Bruce Schneier might be jealous of that one."

Perhaps... but now without VRD!
Imagine a notebook, and throw away the display.
Now strap it in your winter jacket and put a VRD (Virtual Retinal Display) on.

Now you have a netbook with a 50x50inch display that can interact with the outside world...
Ex: Help you repair your car
        A GPS system that show helpful informations directly in your fov
        Help you play virtual battlefield with wooden guns at your favorite parc lol
        etc...etc...etc...

BUT it won't happen with a wrist display...

My point is : They're is nothing impressive with Bing gaining market shares... with the release of Win7 (with BING as default search engine) and the reset of the default search engine to Bing in IE via Windows Update... They're just waiting for a family member to set it back to google... since they don't know how to do it. Just wait and see :)

Razer, Valve, and Sixense Working On Motion Control For PC Games 126

Posted by Soulskill from the trendy-name-guaranteed dept.
An anonymous reader sends along this excerpt from Shacknews: "Gaming hardware developer Razer has announced a new multi-year partnership with Sixense Entertainment and Valve Software to deliver a '...revolutionary true-to-life, next-generation motion sensing and gesture recognition controller for PC gaming.' Razer, Valve, and Sixense, along with a selection of PC OEM partners, are aiming to produce '...ultra-precise one-to-one motion sensing controllers that use electromagnetic fields to track precise movements along all six axes.' Each controller will reportedly track its orientation within a single degree, and detect positioning within one millimeter. Thankfully, the device will be compatible with both current and future generation PC games."

PlayStation Network Expanding To Involve Other Devices 63

Posted by Soulskill from the making-toasters-smarter dept.
At CES, Sony's Kaz Hirai confirmed that the company will build out its PlayStation Network for use with other devices, such as televisions, Blu-ray players, and PCs. Quoting: "... the expansion starts next month with the availability of the PSN video store on these other devices, and Hirai explained they are constructing a mechanism to create a single user ID across the entire network (if you have a PSN account, it's good to go on any other applicable Sony device, and if you create one on another device, it'll work on PSN). And finally, Hirai also announced the formation of a new Sony division — called Sony Network Entertainment, Inc. — to drive this expansion of the PSN service into a Sony-wide network."
