Submission + - Feds Hold Open Competition for Hash Standard (scitedaily.com)

blee37 writes: The federal government is holding an open competition to decide the next secure hash standard, which will be called SHA-3. The winner will be specified as one of a handful of secure hash algorithms approved for use by all federal agencies for digital signatures, secure key-exchange, and similar protocols. With SHA-1 on the way out and SHA-2 having never gained wide adoption, it is likely that a good SHA-3 algorithm would become the de facto standard. The competition is in the second round and 14 algorithms remain.

The feds have used open competitions to select encryption algorithms in the past — for example DES and AES were chosen this way. The open process makes perfect sense because the government wants as many smart people as possible to submit and try to break each other's codes. Modern encryption algorithms no longer rely on the secrecy of their source code because it is assumed that source code will fall into the wrong hands anyway. Furthermore, the open process creates a perception of greater legitimacy. A hash algorithm handed down directly by the government would be suspected of having a "backdoor" allowing national security agencies to read your messages.

Piracy

App Store Piracy Losses Estimated At $459 Million 202

An anonymous reader passes along this quote from a report at 24/7 Wall St.: "There have been over 3 billion downloads since the inception of the App Store. Assuming the proportion of those that are paid apps falls in the middle of the Bernstein estimate, 17% or 510 million of these were paid applications. Based on our review of current information, paid applications have a piracy rate of around 75%. That supports the figure that for every paid download, there have been 3 pirated downloads. That puts the number of pirate downloads at 1.53 billion. If the average price of a paid application is $3, that is $4.59 billion dollars in losses split between Apple and the application developers. That is, of course, assuming that all of those pirates would have made purchases had the application not been available to them for free. This is almost certainly not the case. A fair estimate of the proportion of people who would have used the App Store if they did not use pirated applications is about 10%. This estimate yields about $459 million in lost revenue for Apple and application developers." A response posted at Mashable takes issue with some of the figures, particularly the 75% piracy rate. While such rates have been seen with game apps, it's unclear whether non-game apps suffer the same fate.

Submission + - Tech NGOs working in Haiti

d5w writes: There are a thousand and one NGOs responding in some way to the disaster in Haiti, but the necessary infrastructure is usually overlooked when people give charity donations. (In fact, some popular sites actively downgrade charities for spending on infrastructure.) Here are two organizations responding to Haiti, though, that have a purely tech infrastructure focus:

Télécoms Sans Frontières brings mobile telecom rigs and satellite phones to disaster sites, making sure that responders on the ground can communicate with each other and that individuals can contact families abroad.

MapAction sends experienced GIS people and GPS equipment to provide up-to-date mapping, which is important when the landscape has just changed drastically.

Any others?
Robotics

The Best Robots of 2009 51

kkleiner writes "Singularity Hub has just unveiled its second annual roundup of the best robots of the year. In 2009 robots continued their advance towards world domination with several impressive breakouts in areas such as walking, automation, and agility, while still lacking in adaptability and reasoning ability. It will be several years until robots can gain the artificial intelligence that will truly make them remarkable, but in the meantime they are still pretty awesome."
Programming

An Open Source Compiler From CUDA To X86-Multicore 71

Gregory Diamos writes "An open source project, Ocelot, has recently released a just-in-time compiler for CUDA, allowing the same programs to be run on NVIDIA GPUs or x86 CPUs and providing an alternative to OpenCL. A description of the compiler was recently posted on the NVIDIA forums. The compiler works by translating GPU instructions to LLVM and then generating native code for any LLVM target. It has been validated against over 100 CUDA applications. All of the code is available under the New BSD license."
Linux Business

Submission + - Why non-programmers use Linux

An anonymous reader writes: Author Keir Thomas is not a programmer but both uses and advocates Linux through his books. On the PC World blog, he explains why he loves Linux — everything from the practical and obvious (no viruses), to the more inspirational (Linux fosters communities that bring the best out in people). In a world where developers rule the roost, it's rare to hear the views of humble end-users. If you're not a programmer, what are your reasons for using Linux? Is it just because it's free?

Canon Tries To Shut Down "Fake" Canon Blog 125

Thomas Hawk writes "An interesting twist over at the Fake Chuck Westfall Blog. Fake Chuck (like Fake Steve before him) has a blog out parodying Canon's real Technical Information Advisor Chuck Westfall. It seems that Canon and their lawyers over at Loeb & Loeb are none too fond of all the fun that Fake Chuck and DSLR geeks everywhere have been having at their expense and have sent Fake Chuck's blog hosting company, WordPress, a notice to take the blog down. Canon's lawyers cite that Fake Chuck's blog is 'calculated to mislead recipients,' even though the blog has 'fake' in the title, 'fake' in the URL and 'fake' just about everywhere else in the blog. What in the heck is wrong with Canon? Do they really think that trying to shut down a parody blog is going to make their new 5D Mark II ship any faster?" After Fake Chuck removed the Canon logo from his site, WordPress is standing behind him and has rebuffed Canon's demand.

Birth of the Moon: a Runaway Nuclear Reaction? 355

An anonymous reader writes "How the Moon arose has long stumped scientists. Now Dutch geophysicists argue that it was created not by a massive collision 4.5 billion years ago, but by a runaway nuclear reaction deep inside the young Earth."
Data Storage

Submission + - Hard disk drives suitable for long term storage? 17

MrHatken writes: As many people move to using hard disk drives for online and offline backup one needs to consider possible failure modes. I've heard that if hard disk drives aren't spun up regularly the bearings can lose their lubrication and fail, or the head can stick to the disk when parked. Are these myths or reality? Is there any confirmed data on how often one needs to spin them up and for how long? Further though, how difficult would it be for manufacturers to make hard disk drives that would be suitable for long term storage? Particularly, drives that wouldn't be required to be spun up regularly to ensure they'll still function when needed. It would seem to me that it shouldn't be that hard to do ...

Submission + - First beam in the LHC (web.cern.ch)

spatialguy writes: Geneva, 10 September 2008. The first beam in the Large Hadron Collider at CERN1 was successfully steered around the full 27 kilometres of the world's most powerful particle accelerator at 10h28 this morning. This historic event marks a key moment in the transition from over two decades of preparation to a new era of scientific discovery.

"It's a fantastic moment," said LHC project leader Lyn Evans, "we can now look forward to a new era of understanding about the origins and evolution of the universe."

Feed Engadget: HP's UMPC 2133 revealed (engadget.com)

Filed under: Laptops


We've just received these images of HP's rumored UMPC. Honestly, we have no reason to doubt their authenticity. The HP Compaq 2133 "lifestyle accessory" features a big, scratch resistant 8.9-inch 1366 x 766 (WXGA) display, ExpressCard/54 slot, Wireless LAN, nearly full-sized QWERTY (95% of full), integrated webcam, and optional SSD in a 2.5-pound anodized aluminum sex pot running Vista or Linux. Or so say the tipped images. Funny how the once keyboard-less UMPC-class device has now morphed into an Eee PC-like mini. Still, if this is what we can expect from the UMPC crowd come Silverthorne then you can count us in, HP.

Hardware Hacking

Submission + - Asus EEE PC Hacking (arstechnica.com)

legoman666 writes: Intrepid hardware hacker Torsten Lyngaas cracked open his Eee PC and decked it out with $450 worth of extra hardware, including a GPS receiver, an FM transmitter, Bluetooth, extra USB ports, 802.11n, and an extra 4GB flash storage drive. And it all fits inside the shell. Ryan Paul of Ars writes: "The DIY approach doesn't look particularly compelling when you add up the cost of the machine and the $450 that Lyngaas spent on components, but some hobbyists clearly consider the journey more valuable than the destination. "If you say I could get a much better, powerful, plain old, regular laptop for the same money," Lyngaas wrote in his tutorial, "I say: What's the fun in that?""

Feed Techdirt: Do You Actually Understand What Copyright Is For? (techdirt.com)

One of the more amazing things I've discovered in discussing copyright, patents and trademarks with people is that very few people seem to know what each of those three sets of regulations are actually intended for. It certainly makes reasonable discussion and debate on any sort of reform difficult when a large percentage of people involved in the debate (or, tragically, writing the laws around those regulations) seem to believe the purpose of them is entirely different than it actually is. That's why we've tried to point to some historically interesting discussions on these regulations. Two recent blog posts pointed out something interesting related to all this. The first, comes (again) from copyright expert William Patry, who points to a seven minute video of ordinary people explaining why they think copyright exists. The video itself is by Karl Fogel, who also runs a site called Question Copyright. What the video pretty clearly demonstrates is that most people have no clue why copyright exists, and many assume (as we see in the comments around here) that it's there to "protect" the content creator or to prevent plagiarism. No one seems to note that its true purpose, as per the Constitution, is to promote progress (amusingly, many believe copyright is a much more recent creation). While it may seem a bit simplistic to ask a bunch of random people in a park why they think copyright exists, it's actually fairly important when the vast majority of folks don't fully understand the purpose of copyright -- as that's what allows copyright to be extended and turned into something that goes far beyond its original intentions, as we see today. William Stepp, over at Against Monopoly, highlights this by pointing to a new dissertation called Pimps and Ferrets: Copyright and Culture in the United States . It's 231 pages of copyright history goodness, basically describing how this lack of knowledge and understanding of copyright in the 19th century is what allowed continual copyright expansion in that era as well. What started out as something that could only be held in very, very rare cases (as per James Madison's belief that copyright and patents should be quite limited to avoid abuse) was continually expanded to cover much, much more over time. There have been plenty of stories about how copyright has been expanded and lengthened greatly over the past one hundred years, but it happened for the preceding 100 years as well -- thanks in large part to a near total lack of understanding of the true issues at hand by many of the people involved.
