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."

astroengine writes "Astronomers have spotted something rather odd in the asteroid belt. It looks like a comet, but it's got a circular orbit, similar to an asteroid. Whether it's an asteroid or a comet, it has a long, comet-like tail, suggesting something is being vented into space. Some experts think it could be a very rare comet/asteroid hybrid being heated by the sun, but there's an even more exciting possibility: It could be the first ever observation of two asteroids colliding in the asteroid belt."

SpuriousLogic points out a BBC story which begins "The upper reaches of Earth's atmosphere are much lower than expected, a US Air Force satellite has found. Currently, the ionosphere — a layer of charged particles that envelopes the planet — is at an altitude of about 420km, some 200km lower than expected. The behaviour of the ionosphere is important because disturbances in its structure can upset satellite communications and radar."

The RIAA's new plan to enlist ISPs in its war on file sharing, once it announced it was calling a halt to new consumer lawsuits, is running into rough sledding. Wired reports on the continuing legal murkiness of the RIAA's interpretation of copyright law. And one small ISP in Louisiana asks the recording organization, "You want me to police your intellectual property? What's your billing address?"

joabj writes "Virginia Tech researchers have found that the performance of programs running on multicore processors can vary from server to server, and even from core to core. Factors such as which core handles interrupts, or which cache holds the needed data can change from run to run. Such resources tend to be allocated arbitrarily now. As a result, program execution times can vary up to 10 percent. The good news is that the VT researchers are working on a library that will recognize inefficient behavior and rearrange things in a more timely fashion." Here is the paper, Asymmetric Interactions in Symmetric Multicore Systems: Analysis, Enhancements and Evaluation (PDF).

Kevin 7Kbps writes "Censorship Minister Stephen Conroy announced today that the Australian Internet Filters will be extended to block peer-to-peer traffic, saying, 'Technology that filters peer-to-peer and BitTorrent traffic does exist and it is anticipated that the effectiveness of this will be tested in the live pilot trial.' This dashes hopes that Conroy's Labor party had realised filtering could be politically costly at the next election and were about to back down. The filters were supposed to begin live trials on Christmas Eve, but two ISPs who volunteered have still not been contacted by Conroy's office, who advised, 'The department is still evaluating applications that were put forward for participation in that pilot.' Three days hardly seems enough time to reconfigure a national network."

gadgetopia writes "An article has come out claiming (yet again) that 2009 will be the year of Linux, and bases this prediction on the fact that low-power ARM processors will be in netbooks which won't have enough power to run Windows, but then says these new netbooks will be geared to 'web only' applications which suits Linux perfectly. And, oh yeah, Palm might save Linux, too." The article goes on to skewer the year of Linux thing that seems to show up on pretty much every tech news site throughout December and January as lazy editors round out their year with softball trolling stories and "Year End Lists." We should compile a year-end list about this :)

Ned Nederlander writes "Vint Cerf talks the future of the Internet with Ed Cone: 'I expect to see much more interesting interactions, including the possibility of haptic interactions — touch. Not just touch screens, but the ability to remotely interact with things. Little robots, for example, that are instantiations of you, and are remotely operated, giving you what is called telepresence. It's a step well beyond the kind of video telepresence we are accustomed to seeing today.'"
