IOS 4.1 Jailbroken Already 315

mspohr writes "Just hours after Apple released iOS 4.1 to great fanfare, hardware hackers found a way to jailbreak devices that run the new operating system. More surprising still, there doesn't appear to be anything Steve Jobs can do to stop them in the near future. The exploit in the boot ROM of iOS devices was first announced by iPhone Dev-Team member pod2g. It was soon confirmed by other hackers, who said that because the exploit targets such a low-level part of the operating system, Apple won't be able to stop jailbreakers without making significant hardware changes."

Scientists Cut Greenland Ice Loss Estimate By Half 414

bonch writes "A new study on Greenland's and West Antarctica's rate of ice loss halves the estimate of ice loss. Published in the journal Nature Geoscience, the study takes into account a rebounding of the Earth's crust called glacial isostatic adjustment, a continuing rise of the crust after being smashed under the weight of the Ice Age. 'We have concluded that the Greenland and West Antarctica ice caps are melting at approximately half the speed originally predicted,' said researcher Bert Vermeeersen."

Linux Rescues Battery Life On Vista Notebooks From Dell 200

nerdyH writes "Dell is preparing to ship two enterprise-oriented Windows Vista notebooks with an interesting feature — a built-in TI OMAP (smartphone) processor that can power instantly into Linux. The 'Latitude ON' feature is said to offer 'multi-day' battery life, while letting users access email, the web, contacts, calendar, and so on, using the notebook's full-size screen and keyboard. I wonder if someday we'll just be able to plug our phones into our laptops, switching to the phone's processor when we need to save battery life? Or, maybe x86 will just get a lot more power-efficient. Speaking at MontaVista's Vision event today, OLPC spokesperson and longtime kernel hacker Deepak Saxena said the project is aiming for 10-20 hours of battery life during active use, on existing hardware (AMD Geode LX800 clocked at 500MHz, with 1GB of Flash and 256MB of RAM)."

Microsoft Updates Multiple Sysinternals Tools 179

wiedzmin writes "A couple of very useful updates have just been released by Microsoft for the ever so popular Sysinternals tool set. The most notable one is ProcessMonitor v2.0 which will now include 'real-time TCP and UDP monitoring.' Another one, released earlier this year — Desktops 1.0, provides a very unique multi-thread way to get multiple desktops running on your Windows box."

South Korea's Free Computer Game Business Model Hits the US 159

Anti-Globalism writes with this excerpt from AFP via Yahoo! News: "Seoul-based 'free-to-play' computer game titan Nexon on Wednesday blasted into the US videogame arena with a 'Combat Arms' online first-person shooter title that makes its cash from optional 'micro-transactions' by players. The game makes its money from players that buy animated helmets, outfits, emblems or other virtual items to customize in-game characters. To keep the battlefield even, players earn experience or advanced weaponry by skill so people essentially can't pay for power. ... Startups and established game makers including Japanese goliath Sony are venturing into the free computer game market, according to DFC Intelligence analyst David Cole. 'It looks like it could be very big,' Cole told AFP. 'It's one of the things everybody seems to be looking at. The challenge is it is a very new model and it remains to be seen whether customers used to a free model will be tight when it comes to actually spending money on it.'"

Researchers Re-Examine Second Law of Thermodynamics 125

Many readers have written to tell us that researchers are examining the possibility of using Brownian ratchets to help combat the problem of heat dissipation in miniaturized electronics. "Currently, devices are engineered to operate near thermal equilibrium, in accordance with the Second Law of Thermodynamics which states that heat tends to transfer from a hotter unit to a cooler one. However, using the concept of Brownian ratchets, which are systems that convert non-equilibrium energy to do useful work, the researchers hope to allow computers to operate at low power levels, and harness power dissipated by other functions. 'The main quest we have is to see if by departing from near-equilibrium operation, we can perform computation more efficiently,' Ghosh told iTnews. 'We aren't breaking the Second Law — that's not what we are claiming,' he said. 'We are simply re-examining its implications, as much of the established understanding of power dissipation is based on near-equilibrium operation.'"
