Comment It works surprisingly well (Score 1) 2

by jaria (#38691136) Attached to: IPv6-only Is Becoming Viable

IPv6-only networking does work, surprisingly well. But there are a number of issues as well, and some hard work will be needed to resolve them.

For one, we were early transitioning to this mode and hit many of the bugs in various operating systems and applications. The situation has improved dramatically in the two years since we turned on our IPv6-networking mode, for instance Linux today works much better than it did back then. Still, some bugs remain. And I think the users need to push some of the application vendors to make the updates. For instance, while there now are recent versions of WoW that support IPv6, the same is not true of most other games. Similarly, Skype has known about their lack of support for IPv6-only networking for at least two years. When are they going to publish an update?

Submission + - IPv6-only Is Becoming Viable (ietf.org) 2

Submitted by Anonymous Coward
An anonymous reader writes: With the success of world IPv6 day in 2011, there is a lot of speculation about IPv6 in 2012. But simply turning on IPv6 does not make the problems of IPv4 exhaustion go away. It is only when services are usable with IPv6-only that the internet can clip the ties to the IPv4 boat anchor. That said, FreeBSD, Windows, and Android are working on IPv6-only capabilities. There are multiple accounts of IPv6-only network deployments. From those, we we now know that IPv6-only is viable in mobile, where over 80% (of a sampling of the top 200 apps) work well with IPv6-only. Mobile especially needs IPv6, since their are only 4 billion IPv4 address and approaching 50 billion mobile devices in the next 8 years. Ironically, the Android test data shows that the apps most likely to fail are peer-to-peer, like Skype. Traversing NAT and relying on broken IPv4 is built into their method of operating. P2P communications was supposed to be one of the key improvements in IPv6.

Old People Enjoy Reading Negative Stories About Young 122

Posted by samzenpus from the stupid-kids dept.
A study by Dr. Silvia Knobloch-Westerwick and co-author Matthias Hastall suggests that your grandma's self-esteem gets a boost when she hears about the stupid things young people do. "Living in a youth centered culture, they may appreciate a boost in self-esteem. That's why they prefer the negative stories about younger people, who are seen as having a higher status in our society," said Dr. Silvia Knobloch-Westerwick. From the article: "All the adults in the study were shown what they were led to believe was a test version of a new online news magazine. They were also given a limited time to look over either a negative and positive version of 10 pre-selected articles. Each story was also paired with a photograph depicting someone of either the younger or the older age group. The researchers found that older people were more likely to choose to read negative articles about those younger than themselves. They also tended to show less interest in articles about older people, whether negative or positive."

Tsunami Hit New York City Region In 300 BC 147

Posted by timothy from the no-place-is-completely-safe dept.
Hugh Pickens writes "Scientists say that sedimentary deposits from more than 20 cores in New York and New Jersey indicate a huge wave crashed into the New York City region 2,300 years ago, dumping sediment and shells across Long Island and New Jersey and casting wood debris far up the Hudson River. Steven Goodbred, an Earth scientist at Vanderbilt University, says that size and distribution of material would require a high velocity wave and strong currents to move it, and it is unlikely that short bursts produced in a storm would suffice. 'If we're wrong, it was one heck of a storm,' says Goodbred. An Atlantic tsunami is rare but not inconceivable, says Neal Driscoll, a geologist from Scripps Institution of Oceanography, who is not associated with the research. The 1929 Grand Banks tsunami in Newfoundland killed more than two dozen people and snapped many transatlantic cables, and was set in motion by a submarine landslide set off by an earthquake."

Al-Qaeda Used Basic Codes, Calling Cards, Hotmail 285

Posted by Soulskill from the if-only-the-nsa-watched-the-wire dept.
jd writes "In startling revelations, convicted terrorist Ali Saleh Kahlah al-Marri admitted that Al Qaeda used public telephones, pre-paid calling cards, search engines and Hotmail. Al-Marri 'used a '10-code' to protect the [phone] numbers — subtracting the actual digits in the phone numbers from 10 to arrive at a coded number.' The real story behind all this is that the terrorists weren't using sophisticated methods to avoid detection or monitoring — which tells us just how crappy SIGINT really is right now. If the NSA needs to wiretap the whole of the US because they can't break into a Hotmail account, you know they've got problems. FindLaw has a copy of al-Marri's plea agreement (the tech-related information begins on page 12), and the LA Times has further details on his case."

Flu Models Predict Pandemic, But Flu Chips Ready 216

Posted by ScuttleMonkey from the false-positives-incoming dept.
An anonymous reader writes "Supercomputer software models predict that swine flu will likely go pandemic sometime next week, but flu chips capable of detecting the virus within four hours are already rolling off the assembly line. The U.S. Department of Health and Human Services (HHS), which has designated swine flu as the '2009 H1N1 flu virus,' is modeling the spread of the virus using modeling software designed by the Department of Defense back when avian flu was a perceived threat. Now those programs are being run on cluster supercomputers and predict that officials are not implementing enough social distancing--such as closing all schools--to prevent a pandemic. Companies that designed flu-detecting chips for avian flu, are quickly retrofitting them to detect swine flu, with the first flu chips being delivered to labs today." Relatedly, at least one bio-surveillance firm is claiming they detected and warned the CDC and the WHO about the swine flu problem in Mexico over two weeks before the alert was issued.

ARIN Letter Says Two More Years of IPv4 266

Posted by timothy from the no-more-mister-nice-registry dept.
dew4au writes "A reader over at SANS Internet Storm Center pointed out a certified letter his organization received from ARIN. The letter notes that all IPv4 space will be depleted within two years and outlines new requirements for address applications. New submissions will require an attestation of accuracy from an organizational officer. It also advises organizations to start addressing publicly accessible assets with IPv6. Is ARIN hoping to scare companies into action with the specter of scarce resources? This may be what's needed to spur adoption since there appears to be no business case for IPv6 deployment."

"Miraculous" Stem Cell Progress Reported In China 429

Posted by kdawson from the we-can-cure-it-for-you-wholesale dept.
destinyland writes "In China's Guangdong Province there's been 'almost miraculous' progress in actually using stem cells to treat diseases such as brain injury, cerebral palsy, ataxia and other optic nerve damage, lower limb ischemia, autism, spinal muscular atrophy, and multiple sclerosis. One Chinese biotech company, Beike, is now building a 21,500 square foot stem cell storage facility and hiring professors from American universities such as Stanford. Two California families even flew their children to China for a cerebral palsy treatment that isn't available in the US. The founder of Beike is so enthusiastic, he says his company is exploring the concept of using stem cells to extend longevity beyond 120 years."

Elderly To Get Satellite Navigation To Find Their Way Around Supermarkets 80

Posted by samzenpus from the too-many-aisles dept.
Three government centers in the UK have been working on a way to use digital technology to help the elderly and the disabled. One of their ideas is a supermarket satellite navigation system to help elderly people who get confused by changing layouts in the aisles. Professor Paul Watson, of Newcastle University, said: "Many older people lack the confidence to maintain 'normal' walking habits. This is often due to worries about getting lost in unfamiliar, new or changing environments." A kitchen for Alzheimer's patients packed with hidden sensors and projectors is also in the works.

Some Large Dinosaurs Survived the K-T Extinction 269

Posted by kdawson from the hid-under-a-rock dept.
mmmscience sends along coverage from the Examiner on evidence that some dinosaurs survived the extinction event(s) at the end of the Cretaceous period. Here is the original journal article. "A US paleontologist is challenging one of the field's greatest theories: the mass extinction of dinosaurs at the end of the Cretaceous period. Jim Fassett, a paleontologist who holds an emeritus position at the US Geological Survey, recently published a paper in Palaeontologia Electronica with evidence that points to a pocket of dinosaurs that somehow survived in remote parts New Mexico and Colorado for up to half a million years past the end of the Cretaceous period. If this theory holds up, these dinosaurs would be the only ones that made it to the Paleocene Age."

Using the Internet To Subvert Democracy 202

Posted by kdawson from the you-thought-diebold-was-bad dept.
david_adams writes "All the recent talk about various polls and elections being pranked or hijacked, serious and silly alike, prompted me to write an article about the technical realities behind online polling, and the political fallout of ever becoming subject to online voting for serious elections. Even if we were to be able to limit voting to legitimate, legal voters, the realities of social networking and the rise of Internet-based movements would dramatically alter the political landscape if online voting were to become commonplace."

Tokyo Scientists Create Mobile Slime 111

Posted by samzenpus from the godzilla's-newest-foe dept.
Sockatume writes "Shingo Maeda and colleagues at Waseda University have created a polymer gel that walks under its own chemical power. The team exploited the oscillating Belousov-Zhabotinsky reaction to create periodic changes in the size of the polymer, and built a tensed structure that would amplify those small movements into a horrifically potent gait. The current version only walks across a notched surface, but the team are working on a terrible new form that will cross smooth surfaces like a snail. The team say they intend to apply it in the self-assembly of small structures. Suddenly, I can't stop screaming."
