The Physics of a Rolling Rubber Band
sciencehabit writes "Modern physics can get complicated. Sure, researchers know exactly what forces act on a ball rolling down an inclinemdash;an experiment that helped Galileo develop universal laws for movement and acceleration. But what happens when a deformable shape like a a rubber band rolls around? A new study reveals that the faster it goes, the more squashed it gets.

ATM Hack Gives Cash On Demand
angry tapir writes "Windows CE-based ATMs can easily be made to dole out cash, according to security researcher Barnaby Jack. Exploiting bugs in two different ATM machines at Black Hat, the researcher from IOActive was able to get them to spit out money on demand and record sensitive data from the cards of people who used them. Jack believes a large number of ATMs have remote management tools that can be accessed over a telephone. After experimenting with two machines he purchased, Jack developed a way of bypassing the remote authentication system and installing a homemade rootkit, named Scrooge,"pa href="http://www.facebook.com/sharer.php?u=http%3A%2F%2Fit.slashdot.org%2Fstory%2F10%2F07%2F29%2F0127221%2FATM-Hack-Gives-Cash-On-Demand" target="_blank" title="Share on Facebook"img src="http://a.fsdn.com/sd/facebook_icon_large.png"/a

Nuclear Energy Now More Expensive Than Solar
js_sebastian writes "According to an article on the New York Times, a historical cross-over has occurred because of the declining costs of solar vs. the increasing costs of nuclear energy: solar, hardly the cheapest of renewable technologies, is now cheaper than nuclear, at around 16 cents per kilowatt hour. Furthermore, the NY Times reports that financial markets will not finance the construction of nuclear power plants unless the risk of default (which is historically as high as 50 percent for the nuclear industry) is externalized to someone else through federal loan guarantees or ratepayer funding. The bottom line seems to be that nuclear is simply not competitive, and the push from the US government to subsidize it seems to be forcing the wrong choice on the market."pa href="http://www.facebook.com/sharer.php?u=http%3A%2F%2Fhardware.slashdot.org%2Fstory%2F10%2F07%2F29%2F0249234%2FNuclear-Energy-Now-More-Expensive-Than-Solar" target="_blank" title="Share on Facebook"img src="http://a.fsdn.com/sd/facebook_icon_large.png"/a

FTC Wants Browsers To Block Online Tracking
storagedude writes "The FTC wants a do-not-track mechanism that would allow Web users to opt out of online behavioral tracking, similar to the national do-not-call registry. The agency's preferred method for accomplishing this would be a browser-based tool that would give users the option of blocking data collection across the Web. The only problem is that the agency may not have the authority to require this, thanks to concerted lobbying efforts by the advertising industry. The first step may just be voluntary measures, to be released this fall."pa href="http://www.facebook.com/sharer.php?u=http%3A%2F%2Fyro.slashdot.org%2Fstory%2F10%2F07%2F29%2F0233238%2FFTC-Wants-Browsers-To-Block-Online-Tracking" target="_blank" title="Share on Facebook"img src="http://a.fsdn.com/sd/facebook_icon_large.png"/a

Valve Apologizes For 12,000 Erroneous Anti-Cheating Bans
Earlier this week, there were reports that large numbers of Modern Warfare 2 players on Steam were getting erroneously banned by Valve's Anti-Cheat software. While such claims are usually best taken with a grain of salt, the quantity and suddenness caused speculation that Valve's software wasn't operating correctly. A few days later, Valve president Gabe Newell sent out an email acknowledging that roughly 12,000 players had been inappropriately banned over the preceding two weeks. "The problem was that Steam would fail a signature check between the disk version of a DLL and a latent memory version. This was caused by a combination of conditions occurring while Steam was updating the disk image of a game." Valve reversed the bans and gave free copies of Left 4 Dead 2 to everyone who was affected.pa href="http://www.facebook.com/sharer.php?u=http%3A%2F%2Fgames.slashdot.org%2Fstory%2F10%2F07%2F29%2F0539233%2FValve-Apologizes-For-12000-Erroneous-Anti-Cheating-Bans" target="_blank" title="Share on Facebook"img src="http://a.fsdn.com/sd/facebook_icon_large.png"/a
