Billosaur writes "In the post-Christmas rush to power up and use their new iPods, an onslaught of downloaders brought iTunes to its knees, according to CNN. Monday and Tuesday saw users posting message after message about slow downloads and the iTunes site denying them entry. The heavy traffic was apparently more than the system could bear, what with the large numbers of people receiving iPods and iTunes gift cards. Perhaps Apple was underestimating just how successful they were going to be?"

An anonymous reader writes "CNN writes about a $50,000 machine that can print books on demand. It can print up to 550 pages and put a binding on the book in seven minutes. It will be debuting in a select number of U.S. libraries in 2007. The machine is the 'output' end of a service called On Demand Books, which is also just debuting. From the article: 'Some 2.5 million books are now available - about one million in English and no longer under copyright protection. On Demand accesses the volumes through Google and the Open Content Alliance, among other sources. [Co-founder Dane] Neller predicts that within about five years On Demand Books will be able to reproduce every volume ever printed.'"

s31523 writes "With over 1 billion cell phone users worldwide, and with so many business travelers, using the cell phone on the airplane has been a recent hot topic. Emirate airlines is announcing they will give the OK for cell phone use on their planes, making them the first airline to do so. The FCC and FAA still ban the use, but are working to determine safety implications, if any."

kiran_n sent in an article by Fortune's Owen Thomas on Vista not being compatible with SQL Server. An excerpt: "But now Microsoft has a problem. Vista, its long-awaited update to the Windows operating system, can't run the current version of SQL Server. The company is working on a SQL upgrade that is compatible with Vista — called SQL Server 2005 Express Service Pack 2 — but it's in beta and can be licensed only for testing purposes. Microsoft hasn't set a release date for the new SQL program."

An anonymous reader writes "For the first time in nearly fifty years another mammal, specifically an aquatic mammal, has gone extinct. In this case, it was the white dolphin, also known as the Baiji, which used to live in the Yangtze River in China. The dolphin had been known to exist for the last 20 million years."

Gordon from Seattle writes to mention a CNN article about a new way to hang out. A British aerospace team is working on a super-sticky substance they're calling "Synthetic Gecko". It mimics the hairs on a gecko's foot, and may eventually be developed as a reusable adhesive. From the article: "Each of the microscopic setae on a gecko's foot has a mushroom shaped cap on the end, less than one-thousandth of a millimeter across. This ensures that the gecko's foot is in very close contact with the surface beneath. The cumulative attractive force, called van der Waals force, of these setae allows the lizard to scurry up walls and ceilings, and even hang from polished glass surfaces. In 2003 scientists at the University of Manchester produced a one centimeter patch of 'gecko tape,' but neither the University of Manchester nor University of California teams managed to produce the material in a greater quantity, unlike Haq and Sargent, who have already tested areas larger than 10 centimeters-squared."

KingSkippus writes "Stephen Colbert calls it 'truth that comes from the gut, not books.' Merriam-Webster calls it their 2006 Word of the Year. The word, first introduced [Windows media] on 'The Word' segment of The Colbert Report, won by a five-to-one margin. In spite of Colbert's ironic dismissal of dictionaries and other reference books, will Colbert's coined word actually be added to those books? With media outlets like CNN and MSNBC covering it, the idea may very well have truthiness."

An anonymous reader writes in with a piece in Fortune speculating on what's next for Google. The writer believes that a supersaturated solution of very smart people, plus stock that may have run out of upside, will yield what he calls Son of Google — a large wave of innovative companies created by Google graduates. And a Google less intent on hiring, and less able to hire, the very smartest people around. Could happen.

Virchull tells us about a case the Supreme Court has agreed to hear, in which former special prosecutor Kenneth Starr will take the side of an Alaska school board against a student who displayed a rude banner off school property. The banner read "Bong Hits 4 Jesus" and it got the student suspended. He and his parents sued the school board for violating his First Amendment rights. The case is nuanced: while the student did not display the banner on school property, he did do so during a school function. Starr is said to be arguing the case for free.

mustardayonnaise writes "CNN Money is reporting that graphics chipmakers Nvidia and AMD (who recently acquired NVidia rival ATI) said Friday that they received subpoenas from the US Department of Justice as part of a probe into potential antitrust violations involving graphics processing units and cards. Each company controls about 25% of the entire graphics chip market. According to the article, Intel, who makes their own fair share of graphics chipsets, has yet to be included in the investigation."

feuerfalke writes "Homeland Security recently disclosed a plan regarding an Automated Targeting System, or ATS, that would generate a 'terrorist risk rating' based on information collected about the traveler. This information would include things such as where they are from, how they paid for tickets, their motor vehicle records, past one-way travel, seating preference and the meals they ordered in-flight. These ratings have now been assigned to millions of international travelers, including Americans, and the ATS is exempt from many provisions of the Privacy Act — one cannot view their rating or the information used to generate it."

eldavojohn writes "Project Psiphon has been released for public download under the GPL. CNN has coverage of the Canadian research project that 'works by first allowing a person in a country like Canada that does not censor Internet content to set up a user name and a password for a person in a country that does — China, for example.' While this idea is certainly nothing new to Slashdot, the fact that software like Psiphon is becoming publicly available is interesting. For a quick simplified 'How it works,' Psiphon has a Flash demonstration." Not a moment too soon, apparently. China is moving to assign IDs to bloggers, to register their real identities and track their statements online.

antifoidulus writes "CNN is reporting on a study that shows that not only did Americans buy more fuel efficient vehicles in 2005 (although sadly this trend reversed itself in the later half of 2006) but they also drove slightly less on average, according to the article, 'The drop in driving was small — the average American drove 13,657 miles (21,978.8 km) per year in 2005, down from 13,711 miles in 2004.' This is the first drop since the energy crisis of the late 70's. However, although SUV and mini-van sales have been falling, they still represent over half of the private vehicle sales in the United States."

smooth wombat writes "Stephen Hawking, Lucasian Professor of Mathematics at the University of Cambridge, has been awarded the Royal Society's 275th Copley medal for his contribution to cosmology and theoretical physics. Other notables to receive the award, established by Stephen Gray in 1731 'For his new Electrical Experiments', include Charles Darwin, Louis Pasteur and Albert Einstein. In his remarks, Professor Hawking reiterated his previous comments that man must colonize other planets. The medal presented to Professor Hawking was sent into space onboard Space Shuttle Discovery and spent some time on the International Space Station in July of this year. Hawking has expressed an interest in going into space and commented, 'My next goal is to go into space, maybe Richard Branson will help me.'"

pyrbrand writes "Despite the iFanboy jabber that Zune sales were horrific, CNN has a story to the contrary. Turns out Zune was the #2 Digital Audio player in its first week of sales. Not a bad start for the challenger to the iPod throne. As others have pointed out the Amazon sales rank may have been thrown off by Zune sales being divided between the three colors."

FST writes "CNN.com is reporting on a study which found that those 'who play violent video games show increased activity in areas of the brain linked to emotional arousal and decreased responses in regions that govern self-control.' The Reuters article goes on to discuss the study's details, which is fairly typical for these types of inquiries. After playing games, young people were required to do tasks requiring 'processing of emotional stimuli', and concentration. Their brains were monitored for activity, and the findings were presented at a recent meeting of the Radiological Society of North America." The article then gets a little preachy. From the article: "The $13 billion U.S. video game industry, with revenue rivaling Hollywood box office sales, is at the center of a cultural battle over violent content. Lawmakers' various attempts to ban the sale of violent video games to children have been blocked by courts in Louisiana, Illinois, California, Michigan, and Minnesota... Numerous behavioral and cognitive studies have linked exposure to violent media and aggressive behavior." Numerous studies have said just the opposite, too.

eldavojohn writes "CNN is running a story on the increasingly-lucrative market for casual gaming. The article mentions that the latest PopCap game 'Bookworm Adventures' cost $700,000 to create. At $30 a pop for the title, PopCap is almost certain to make a profit." From the article: "Casual gamers play to relax -- the same reason people play solitaire, dominoes or mahjong. The games can be played for 5 minutes -- while the baby is sleeping or between office meetings -- or for hours at a stretch in a Zen-like trance. Big Fish Games Inc. released its most expensive title -- 'Travelogue 360: Paris' -- earlier this month. The Seattle-based company spent $300,000, hired seasoned illustrators and photographers, and bought the rights to images of historic landmarks like the Eiffel Tower. Players scour Paris for souvenirs as they are interviewed for an article in a travel magazine."

Robotech_Master writes, "Long-time Slashdot veterans will remember Jon Katz, the editorial writer whose Slashdot articles invariably generated heated controversy. It appears he may have the last laugh; how many of the Slashdot posters who ridiculed him went on to be played by Jeff Bridges in a movie? From the article: 'In his new book, "A Good Dog: The Story of Orson," Katz chronicles the life and death of the lovable but troubled border collie that transformed his life. It continues the story begun in Katz's last book, "A Dog Year," now being made into a movie starring Jeff Bridges as Katz.' Katz critics may get a chuckle out of the plot synopsis for the film: 'A man having a mid-life crisis has his life turned upside down when he takes in a border collie crazier than he is.'" The film should be released in late 2007.

l2718 writes "In a new take on the reach of 'Intellectual Property,' the Mapuche Indians of Chile are accusing Microsoft of linguistic piracy. Their lawsuit alleges that Microsoft needed permission from the tribal elders before translating its software into Mapuzugun, a project which was co-ordinated with the Chilean Ministry of Education." From the CNN Money article: "The Mapuche took their case to a court in the southern city of Temuco earlier this month but a judge ruled it should be considered in Santiago. A judge in the capital is due to decide in the next two weeks whether Microsoft has a case to answer. 'If they rule against us we will go to the Supreme Court and if they rule against us there we will take our case to a court of human rights,' said Lautaro Loncon, a Mapuche activist and coordinator of the Indigenous Network, an umbrella group for several ethnic groups in Chile."

Petersko writes "It appears Amazon is about to be sued for patent infringement by IBM". From the article: "Hundreds of other companies have licensed the same patents, and IBM has tried to negotiate licensing deals with Amazon "over a dozen times since 2002," Kelly said. Amazon.com, which has bought a lot of hardware from Hewlett-Packard Co. over the years but not IBM, has allegedly refused every time."

tanman writes "The California Supreme Court has ruled that websites which publish libelous text written by third parties cannot be sued for libel, reports CNN. The ruling found for the defendant, who was backed by the likes of Amazon, Microsoft, and Google. The internet service companies following the case feared that a ruling against the defendant would find them liable for content posted to their respective websites. Even though the court allowed this could have far-reaching consequences, they ultimately wanted this to be a question more for Congress than the courts." From the article: "The case centers on an opinion piece sent via e-mail to Ilena Rosenthal, a woman's health advocate who runs various message boards and promotes alternative medicine. The scathing missive, written by Tim Bolen, accused Dr. Terry Polevoy, of Canada, of stalking a Canadian radio producer and included various invectives directed at Polevoy and Dr. Stephen Barrett, of Pennsylvania. The two doctors operated Web sites devoted to exposing health frauds. After Rosenthal posted the piece to two newsgroups, Polevoy and Barrett sued her, Bolen and others for libel. The lawsuit accuses Rosenthal of republishing the information after being warned it was false and defamatory."

Dr. Eggman writes, "The AP has a short technology piece on the mechanics that go into the motion-sensing capabilities of the Wii and PS3 controllers. It also details some of the past uses of the technology and gives a nice overview of just how far the technology has come from the earliest missile-guidance sensor equipment."

If you're having trouble picking, the reviews are beginning to come in for the PlayStation 3 and the Wii. Chris Morris at CNN offers an analysis of the Wii launch games and some frustrations about the PlayStation 3. Chris Kohler at C|Net offers a side by side comparison of both systems ... and some frustrations about the PS3 controller. Finally, 1up offers a look back at Sony's launches, and a similar look back at Nintendo's launches in an effort to judge how the weekend will go.

Geekgal writes "Red Hat has slammed the door shut on any possibility of entering into a patent protection deal similar to the one Microsoft recently announced with Novell, eWeek is reporting. While Microsoft has repeatedly said it wants to work with Red Hat and would like to structure a relationship where its customers can be assured of the same thing as Novell's customers now are, Mark Webbink, Red Hat's deputy general counsel, says 'we do not believe there is a need for or basis for the type of relationship defined in the Microsoft-Novell announcement.' Interestingly enough, Microsoft also says that it has not ruled out going it alone and providing some sort of indemnification for its customers who also use Red Hat Linux." Meanwhile, Eben Moglen, the FSF general counsel, promises that GPLv3 will explicitly outlaw deals like this. (Of course everyone's on v2, so calling the Novell deal "DOA" would be premature.)

Salvance writes "Google's CEO Eric Schmidt envisions a day when all cell phones are free if the user agrees to watch targeted ads. While he provides no specific plans for Google to give away phones, the implication is that he expects such moves in the future given Google's current pilot successes with delivering text ads on phones." From the article: "Schmidt also said his company was working on how to allow users to maintain basic control of their personal data. Currently, Google stores consumer data on hundreds of thousands of its own computers in order to provide additional services to individual users. The company is looking to allow consumers to export their Web search history or e-mail archives and move them to other sites, if they so choose."

ClickOnThis noted that NASA is actually avoiding a Shuttle in Space over New Years. It says "The worry is that shuttle computers aren't designed to make the change from the 365th day of the old year to the first day of the new year while in flight. NASA has never had a shuttle in space December 31 or January 1. 'We've just never had the computers up and going when we've transitioned from one year to another,' said Discovery astronaut Joan Higginbotham. 'We're not really sure how they're going to operate.'" You may notice some deja vu while reading this story. Sorry. Not much happens on Sundays :)

thejrwr writes to mention a CNN article about the ballpark stadium of the future. The new Cisco stadium for the Oakland A's will be a paragon of the company's technologies, with cellphones carrying personal data used for advertising and identification purposes. "Cisco, which makes the routers, switches and other devices used to link networks and direct traffic on the Internet, is trying to shed its image as solely a maker of networking infrastructure gear. The company also hopes to capitalize on products and services that utilize the network. One example is TelePresence, a technology similar to video conferencing that Cisco introduced last month that aims to deliver a three-dimensional feeling that the participants are all in the same room."

ScentCone writes "New Zealand's Qualification Authority (which sets testing standards for the public schools) is confident that those grading papers will understand the meaning of students' responses, even if they use phone/IM-style text-speak. From the article: 'credit will be given if the answer "clearly shows the required understanding," even if it contains text-speak.' Many teachers are not amused, and critics say that the move will devalue NZ's equivalent of a high school diploma." Not to mention that graders will need to be restrained so they don't gouge their own eyes out. While in the medium of text messages, some shorthand might be in order, but I didn't realize that world paper, pencil, and ink shortages were so severe so that text-speak is necessary everywhere.

Chris Morris, of CNN Money's Game Over column, has several final details on the next-gen consoles. He delves into availability, games, the new ads for both the Wii and the PS3 and (of course) "Who's going to win?" From the article: "For the past two generations, Sony has sold far more PlayStation units than its competitors have sold of their systems. Publishers, for their part, expect the field to be a lot more even over the next five years or so (which should be about the time you're asked to start focusing on the PS4, Xbox 720 and whatever funky name Nintendo comes up with next)."

MCTFB writes, "According to CNN, human beings may have acquired a gene for developing bigger brains from Neanderthal man. Apparently, 70% of the world's population has a variant of a gene regulating brain size, with this variant being most common in people of European descent (where Neanderthal man lived alongside ancient humans), and least common in people of African descent (where Neanderthal man was non-existent). While modern day eugenicists might all too eagerly read into these findings to draw their own politically biased conclusions, people such as myself, who happen to be of northern European ancestry, may find it fascinating that somewhere in our lineage ancient humans and Neanderthals decided to make love and not war on the ancient plains of Eurasia."

macinrack writes to tell us that Defense Secretary Donald Rumsfeld, architect of the unpopular war in Iraq, intends to resign after six stormy years at the Pentagon. Officials said Robert Gates, former head of the CIA, would replace Rumsfeld.

Every news publication on earth is saying mostly the same thing. The Democrats have taken the house picking up a sizable number of seats. But the Senate remains a tossup with a few undecided seats holding the balance. Concerns of voter fraud have been heard from around the nation as well.

Neovanglist writes "CNN, FOX, and MSNBC are reporting that voting machines in three states (Ohio, Indiana, and Florida) have already been showing issues, both in the machines themselves and in the training of poll attendants, causing many districts to switch to paper ballots." From the article: "Voters put the Republican congressional majority and a multitude of new voting equipment to the test Tuesday in an election that defined the balance of power for the rest of George W. Bush's presidency. Both parties hustled to get their supporters out in high-stakes contests across the country, Democrats appealing one more time for change, and appearing confident the mood was on their side. Republicans conceded nothing as their vaunted get-out-the-vote machine swung into motion." If you're in the U.S., and you haven't voted already, go do it!

tanman writes "CNN reports that NASA Administrator Michael Griffin has agreed to send astronauts on one final mission to repair the Hubble Space Telescope. No date was reported for the mission, other than before the shuttle fleet is retired. From the article, 'A rehab mission would keep Hubble working until about 2013. It would add two new camera instruments, upgrade aging batteries and stabilizing equipment, add new guidance sensors and repair a light-separating spectrograph. Without a servicing mission, Hubble will likely deteriorate in 2009 or 2010.'"

ExE122 writes "CNN and CareerBuilder have posted a listing of the top 10 dirtiest jobs in science. 'Whether they are sifting through reeking mud banks to find cures for contamination, or sorting stool samples to get to the bottom of our bathroom dilemmas, these are some of the science jobs that sacrifice their time, energy and comfort for the greater global good.' Sounds like a job opportunity for Mike Rowe!" From the article: "Hot-zone Superintendent - What they do: Perform maintenance work for bio-safety labs that study lethal airborne pathogens, for which there is no known cure. Their work enables scientists to study the nature of disease-causing organisms, such as anthrax."

Bennett Haselton writes "The Associated Press is writing that "DVD Jon", known for breaking the copying restrictions on DVDs, plans to market a method for breaking the copy protection on songs purchased from iTunes Music. What's missing from the story is the fact that converting iTunes music into unrestricted formats like MP3 is already trivial. In principle it's impossible to prevent music from being copied anyway, because a user can always play a song through an audio output jack and use another device to record the sound; there are several other methods that work by reducing the same principle to practice. Bottom line: there's no reason yet to get excited about the iTunes-cracking technology (and, indeed, no reason to buy an iPod), when you can already convert songs this way." Bennett's full article on the subject is available below.

According to an Associated Press story, "DVD Jon" Johansen is planning to market a technology for cracking the copy protection on songs purchased from Apple's iTunes Music Store.

This technology will probably be much discussed in the press as the release date draws nearer, but it's a case of using a flame thrower to kill a fly. It's already possible to convert Music Store songs to MP3 without even using any functionality outside of iTunes.

Apple doesn't make this easy to find, of course, and in fact tries to make it look impossible -- if you set your preferred import format to MP3, then right-click on a song in your iTunes "Purchased songs" list and click "Convert selection to MP3", you get the error: "[song name] could not be converted because protected files cannot be converted to other formats". But you can easily burn a series of songs to a CD, then select the songs on the CD and import them into MP3 format. (Of course, if you don't like wasting a writable CD each time you convert your songs, then wait until you've purchased a few more songs and convert them all at once.) All of this is based on core iTunes functionality, which won't go away unless Apple decides to stop letting users (a) burn CDs or (b) import CD songs as MP3 files, neither of which is likely.

But suppose Apple does manage to block this path. (The easiest way I can see would be to write a hidden code on each CD burned from protected songs with iTunes, so that iTunes would refuse to re-import that CD into an unprotected format. Users could re-import the songs with another application, but at least they'd have to open two programs!) You can still use a program like Total Recorder that can capture any sound output on the computer and save it to an MP3 file.

And even if it ever becomes possible for the audio playback application to seize control of the operating system in order to stop programs like Total Control from working, you can always connect a portable MP3 recorder to the audio output of your computer.

It's a common misconception that if a copy-protection algorithm gets broken, it must be because the encryption was too weak or the algorithm was flawed. But the Achilles heel of any such copy-protection scheme is that in order for the content to be playable, the playback program has to "break" the encryption every time, in order to play it. If the content is encrypted using a key, the key has to be stored on the user's computer where the playback program can find it. (If you didn't have to store the key along with the encrypted content, you could use encryption algorithms that are believed to be impossible to break with today's computers, by 15-year-old Norwegians or anybody else.) But even though every copy-protection algorithm is breakable in principle, it's usually easier just to capture the content as it's played back, which is what the previous examples do.

Logically, I think the only algorithm that would help to fight music piracy would be one that embeds a unique "fingerprint" or "watermark" in each downloaded copy of a song -- in the audio itself. A good fingerprint would have these properties:

• it should not be noticeable enough to interfere with the user's enjoyment of the song
• it should not be possible to copy the song in a way that destroys the fingerprint, without degrading the song quality and diminishing its value

A good example is the "cap code" dots that appear in certain frames of a movie; these are supposed to be unique to each movie theaters so that pirated movies can be traced to the theater where they were filmed off the screen. This, of course, doesn't make the film traceable to the individual pirate who filmed it, but it makes the movie theater accountable, and incentivizes them to prevent piracy. Unfortunately the "cap code" dots tend to fail the first criteria above -- people do find them annoying, to the point where they're nicknamed "crap code". (It would also be easy to remove them from pirated copies, but few people bother, since the cap code only gets the movie theater in trouble; it doesn't incriminate the individual movie pirate.) We can only hope that any fingerprints embedded in song files are a lot less intrusive.

In the meantime, don't get taken in by the hype around a new way to "crack" the existed restrictions on copy-protected song files. They were never really protected.

Apocalypse111 writes, "According to CNN.com, air samples taken over North Korea have not yet shown any radiation from the event on Monday that North Korea claims was a nuclear test. This is not definitive proof that the event was non-nuclear, as it may either have been so small and deep that it did not let any radioactive debris escape, or perhaps the North Koreans sealed the site." Furthering speculation over whether North Korea has actually exploded a nuclear device, vk38 writes to point out a (free) article in today's Wall Street Journal claiming that the blast could have been set off by exploding fertilizer (ammonium nitrate). The article points to the Texas City disaster of 1947, in which 7,700 tons of ammonium nitrate exploded in the hold of a ship with the estimated power of 2 to 4 kilotons of TNT.
Update: 10/14 08:03 GMT by Z : The story at CNN has been updated: "A preliminary analysis of air samples from North Korea shows 'radioactive debris consistent with a North Korea nuclear test,' according to a statement from the office of the top U.S. intelligence official."

Are these the brilliant ideas that will change the world (and make you rich in the process)?" From the article: "Delivery of new types of Web search to mobile phones. Google, Microsoft, and Yahoo are all taking a swipe at this, but Rimer believes they're betting on a losing strategy by simply shrinking their existing desktop features into a handheld package. He says he's willing to invest in new search applications that, for example, depend as much on voice recognition as on text input and would offer up everything from shopping and news headlines to driving directions and restaurant reviews with a few voice commands and keystrokes ... What he'll invest: $2 million for a working demo application."

eldavojohn writes, "A new robot named Haile (pronounced hi-lee), which 'listens' to what musicians are playing and play along with them, has been developed at the [corrected] Georgia Institute of Technology. There are some videos at the GATech site. From the article: "If the musicians change the beat or rhythm, Haile is right there with them. 'With Haile there are two levels of musical knowledge... The basic level is to teach it to learn to identify music, to imitate,' Weinberg said. 'The higher level is stability of rhythm, to be able to distinguish between similar rhythms. In essence, Haile has the ability to recognize if a rhythm is more chaotic or stable, and can adjust its playing accordingly.' I don't know about the rest of Slashdot, but I can't wait for the day when I have my very own Robo Puente to play along with."
