Hidden Debug Mode Found In AMD Processors 154

Posted by timothy from the sooper-seekrit dept.
An anonymous reader writes "A hidden (and hardware password protected, by means of required special values in processor registers) debug mode has been found in AMD processors, and documented by a reverse engineer called Czernobyl on the RCE Forums community today. It enables powerful hardware debugging features long longed for by reverse engineers, such as hardware data-aware conditional breakpoints, and direct hardware 'page guard'-style breakpoints. And the best part is, it's sitting right there in your processor already, just read the details and off you go with the debugging ninja powers!"

Wikipedia Reveals Secret of 'The Mousetrap' 244

Posted by timothy from the take-that-wikileaks dept.
Hugh Pickens writes "CIOL reports that Wikipedia has revealed the secret of Agatha Christie's famous murder mystery 'The Mousetrap' by identifying the killer in the world's longest running play, now at over 24,000 performances ever since its maiden performance in 1952, despite protests from the author's family and petitions from fans who think the revelation is a spoiler. Angry at the revelation, Matthew Prichard, Christie's grandson, who describes the decision of Wikipedia as 'unfortunate,' says he will raise the matter with the play's producer, Sir Stephen Waley-Cohen. 'My grandmother always got upset if the plots of her books or plays were revealed in reviews — and I don't think this is any different. It's a pity if a publication, if I can call it that, potentially spoils enjoyment for people who go to see the play.' Unrepentant, Wikipedia justifies the decision to reveal the ending of the play. 'Our purpose is to collect and report notable knowledge. It's exceedingly easy to avoid knowing the identity of the murderer: just don't read it.'"

Facebook Says It Owns 'Book' 483

Posted by samzenpus from the first-book dept.
An anonymous reader writes "The Chicago Tribune is reporting that Facebook has sued a tiny start-up called Teachbook.com over the use of 'book' in its name. The start-up, which has two employees, aims to provide tools for teachers to manage their classrooms and share lesson plans and other resources. 'Effectively they're bombing a mosquito here, and we're not sure why they want to do that,' Teachbook.com co-director Greg Shrader told the Tribune. Facebook said its use of 'book' in its name is 'highly distinctive in the context of online communities and networking websites.' Facebook apparently is alleging that no other online 'network of people' can use the word 'book' in its name without violating its trademark."

National Park Service Says Tech Is Enabling Stupidity 635

Posted by samzenpus from the you-got-yourself-into-this-mess-now-get-yourself-out dept.
theodp writes "The National Park Service is finding technology to be a double-edged sword. While new technologies can and do save lives, the NPS is also finding that unseasoned hikers and campers are now boldly going where they never would have gone before, counting on cellphones, GPS, and SPOT devices to bail them out if they get into trouble. Last fall, a group of hikers in the Grand Canyon called in rescue helicopters three times by pressing the emergency button on their satellite location device. When rangers arrived the second time, the hikers complained that their water supply tasted salty. 'Because of having that electronic device, people have an expectation that they can do something stupid and be rescued,' said a spokeswoman for Grand Teton National Park. 'Every once in a while we get a call from someone who has gone to the top of a peak, the weather has turned and they are confused about how to get down and they want someone to personally escort them. The answer is that you are up there for the night.'"

International links are a bottleneck everywhere, which is why people have devised clever ways around them. Seriously popular content is cached by transparent proxies or Content Delivery Networks such as Akamai which reside inside your high-speed network. Also, having a national high-speed network in a country with plenty of space will be very attractive to tech investors to actually move their data to Australia, bringing the data to you instead of having to pull it in from abroad.

Do not underestimate the capacity of DWDM backbones. Also, realize that this gigabit speed is peak capacity, users will scarcely use this capacity for extended periods of time. I also expect that subscriptions will be differentiated with the 1G subscription being more expensive than less demanding plans. 100Mbps will be plenty for most users, but it would be great if customers with higher demands willing to pay the price could get a higher speed.

Tony Abbott apparently doesn't understand a thing about modern networking. Today's optic fibers can support frightening data rates, the limiting factor currenly is what the hardware on both sides is capable of. With the speeds of the high end of the market recently increasing to 40G and 100G (from 1G and 10G) per channel I would not be surprised if that jump suddenly made 1G FTTH possible. Investing in copper technology now is outrageous and a waste of money. Utilizing it for the last mile while you're not done rolling out fiber to each premise is acceptable at best. Wireless broadband might be acceptable for remote locations but even those base stations need a good fiber connection for their uplink.

Cache On Delivery — Memcached Opens an Accidental Security Hole 149

Posted by timothy from the everything-has-a-downside dept.
jamie spotted this eye-opening presentation (here's a longer explanation) about how easy it is to access sensitive data on many sites using memcached, writing "If you already know what memcached is, skim to slide #17. The jaw-drop will happen around slide #33. Turns out many websites expose their totally-non-protected memcached interface to the Internet, including gowalla, bit.ly, and PBS."

New Russian Weapon Hides In Shipping Container 618

Posted by kdawson from the now-you-see-it dept.
shmG writes "A Russian company is marketing a devastating new cruise missile system that can be hidden inside a shipping container, giving any merchant vessel the capability to wipe out an aircraft carrier. Potential customers for the formidable 'Club-K' system include Kremlin allies Iran and Venezuela, say defense experts. They worry that countries could pass on the satellite-guided missiles, which are very hard to detect, to terrorist groups. This is a scary new development in the global arms race that allows for the proliferation of cruise missiles to anyone who will pay for them — even terrorists. This could be the next big thing in strategic weapons, as they can appear anywhere there is a container ship. The company even made a commercial and posted it onto the Internet." The article notes that a Russian defense expert said that "as far as he understood, the Club-K was still at the concept stage."

Wisconsin Designates State Microbe 102

Posted by samzenpus from the the-fighting-parameciums dept.
Hugh Pickens writes "The NY Times reports that state legislators in Wisconsin raced against the clock to pass a bill designating Lactococcus lactis as Wisconsin's official state microbe. 'The first time I heard the idea, I thought, I've got more important things to do than spending my time honoring a microbe,' says Gary Hebl, a Democratic state representative who proposed the bill which, he says, would make Wisconsin the first state in the nation to grant such a designation, 'but this microbe is really a very hard worker,' added Hebl, referring to the bacterium supported by the Department of Bacteriology at UW — Madison used to make cheddar, Colby, and Monterey Jack cheese. The proposal faced only one detractor in committee ('the opponent was clearly lactose-intolerant,' says Hebl), and there was no sign of a last-minute campaign from other bacteria, so by evening, the Assembly had approved the measure, 56 to 41. In case there were any doubts about Wisconsin's priorities, a separate bill also awaits consideration in Madison, declaring cheese Wisconsin's state snack."

Why "Running IT As a Business" Is a Bad Idea 364

Posted by kdawson from the guerilla-movement dept.
snydeq sends along a provocative piece from Infoworld, arguing that the conventional wisdom on how IT should be run is all wrong. "Bob Lewis dispels the familiar litany that 'IT should be run as a business,' instead offering insights into what he is calling a 'guerilla movement' to reject conventional 'IT wisdom' and industry punditry in favor of what experience tells you will work in real organizations. 'When IT is a business, selling to its "internal customers," its principal product is software that "meets requirements." This all but ensures a less-than-optimal solution, lack of business ownership, and poor acceptance of the results,' Lewis writes. 'The alternatives begin with a radically different model of the relationship between IT and the rest of the business — that IT must be integrated into the heart of the enterprise, and everyone in IT must collaborate as a peer with those in the business who need what they do.' To do otherwise is a sure sign of numbered days for IT, according to Lewis. After all, the standard 'run IT as a business' model had its origins in the IT outsourcing industry, 'which has a vested interest in encouraging internal IT to eliminate everything that makes it more attractive than outside service providers.'"

Why Computers Suck At Math 626

Posted by Soulskill from the must-be-lit-majors dept.
antdude writes "This TechRadar article explains why computers suck at math, and how simple calculations can be a matter of life and death, like in the case of a Patriot defense system failing to take down a Scud missile attack: 'The calculation of where to look for confirmation of an incoming missile requires knowledge of the system time, which is stored as the number of 0.1-second ticks since the system was started up. Unfortunately, 0.1 seconds cannot be expressed accurately as a binary number, so when it's shoehorned into a 24-bit register — as used in the Patriot system — it's out by a tiny amount. But all these tiny amounts add up. At the time of the missile attack, the system had been running for about 100 hours, or 3,600,000 ticks to be more specific. Multiplying this count by the tiny error led to a total error of 0.3433 seconds, during which time the Scud missile would cover 687m. The radar looked in the wrong place to receive a confirmation and saw no target. Accordingly no missile was launched to intercept the incoming Scud — and 28 people paid with their lives.'"

Installing Linux On Old Hardware? 507

Posted by Soulskill from the where-are-those-old-telegraph-drivers dept.
cptdondo writes "I've got an old laptop that I've been trying to resurrect. It has a 486MHz CPU, 28 MB of RAM, a 720 MB HD, a 1.44MB floppy drive, and 640x480 VESA video. It does not have a CD drive, USB port, or a network port. It has PCMCIA, and I have a network card for that. My goal is to get a minimal GUI that lets me run a basic browser like Dillo and open a couple of xterms. I've spent the last few days trying to find a Linux distro that will work on that machine. I've done a lot of work on OpenWRT, so naturally I though that would work, but X appears to be broken in the recent builds — I can't get the keyboard to work. (OK, not surprising; OpenWRT is made to run on WiFi Access Point hardware which doesn't have a keyboard...) All of the 'mini' distros come as a live CD; useless on a machine without a CD-ROM. Ditto for the USB images. I'm also finding that the definition of a 'mini' distro has gotten to the point of 'It fits on a 3GB partition and needs 128 MB RAM to run.' Has Linux really become that bloated? Do we really need 2.2 GB of cruft to bring up a simple X session? Is there a distro that provides direct ext2 images instead of live CDs?"

What is the Current State of Home Automation? 409

Posted by ScuttleMonkey from the skynet-wants-your-home-to-be-wired dept.
StonyCreekBare writes "What do people have to say about the current state of Home Automation software? Preferably Linux based, but mainly the field in general, and principally the DIY flavors as opposed to the upscale turnkey systems. I am familiar with Misterhouse, HomeSeer and Automated Living's HAL2000, all of which have serious flaws and weaknesses, but which sometimes succeed well in specific areas. But in all cases, the state of the art seems to have moved little in the last decade. Is any interesting work being done in this space? Or should I just grab one of the three and try to mold it to fit my vision of what it should be? Misterhouse at least is open source so I can add new features, but it has not had an update in a long long time and seems to be missing some modern stuff. The other two are expensive and closed source, and from all I can see, quite flawed, not the least by their dependence on intimate ties to Microsoft. Yet they seem to offer a lot more than Misterhouse despite their weaknesses. Is the Home Automation field as bleak as it appears? Or have I missed the forest for the trees?" What home automation projects have people tackled? Any examples of wild success or failure?
