Bob Briscoe (Chief researcher at the BT Network Research Centre) is on a mission to tackle one of the biggest problems facing the Internet. He wants the world to know that TCP (Transmission Control Protocol) congestion control is fundamentally broken and he has a proposal for the IETF to fix the root cause of the problem. The Internet faced its first congestion crisis in 1986 when too much network traffic caused a series of Internet meltdowns when everything slowed to a crawl. Today’s problem is more subtle and lesser known since the network still appears to be working correctly and...

Utah Internet service providers could earn a state-approved "G-rating" for filtering content and insuring that users could not access pornography under provisions in a bill heard by a House committee on Monday.

I'm interested in any FReeper experience or knowledge about Montessori schooling, formal or home. We are looking into placing our daughter (5 yrs old) into a Montessori preschool.

By the time Bill (not his real name) left the Church of Scientology a few years ago, he had amassed quite a collection of Scientology material—mostly books, tapes, e-meters. But ex-members of Scientology (especially staff members) find themselves in a difficult spot in this regard when they leave Scientology: their books, tapes, and e-meters are only valued by Scientologists, who, quite inconveniently, are strongly discouraged (read: disallowed) from communicating with ex-members—as any ex-Scientologist will tell you. Not surprisingly, he turned to eBay, where a Scientologist buyer can remain blissfully unaware that his seller is a declared suppressive person. But every...

Here ya go. Unload on 'em. :-)

Last night we told you about Qtrax, a new P2P service aimed at combating illicit P2P by offering a legit service that compensates artists and labels via enforced advertising. In that story we briefly noted that Qtrax didn't appear to have all of its ducks in a row: the company was saying that it had signed all four major music labels, when it appeared that they hadn't. At the time it was rather unclear, however, because Qtrax told both Reuters and Wired that it had the necessary signatures. When midnight came and went last night without an official launch, it...

A 15-year-old Australian liver transplant patient has defied modern medicine by taking on her donor's immune system. Demi-Lee Brennan had a liver transplant after she suffered liver failure. Nine months later, doctors at Sydney's Westmead Children's Hospital were amazed to find the teenager's blood group had changed to the donor's blood type. Further tests revealed the stem cells from the donor liver had penetrated her bone marrow. Dr Michael Stormon says he and his colleagues were even more surprised when they found the girl's immune system had almost totally been replaced by that of the donor, meaning she no longer...

"In response to requests for even easier access to the Binary Formats, Microsoft has agreed to remove any intermediate steps necessary to get the documentation. They're going to just post it, making it directly available as a download on the Microsoft web site. Microsoft will also make the Binary Formats subject to its Open Specification Promise by February 15, 2008. They're even planning to include an Open Source converter implementation."

Zetix is a fabric so strong it will resist multiple car bomb blasts without breaking. It absorbs and disperses the energy from explosions thanks to an inner structure so adamantiumtastic it can be used in body armor, window covering, military tents and hurricane defenses—it might even be able to fend off my ex-wife. When not shielding from explosions, it can be used as medical sutures that won't damage body tissue. All of this is thanks to a property that apparently defies the laws of physics: Zetix is built around the principle of auxetics: objects that actually get fatter the more...

A week after signaling her intention to appeal the $222,000 copyright infringement verdict handed down by a federal jury, Jammie Thomas has filed her notice of appeal with the US District Court for the District of Minnesota. Somewhat surprisingly, Thomas is citing the amount of the award as her grounds for the appeal, rather than the jury instructions. According to a copy of Thomas' motion seen by Ars, Thomas wants a retrial on the actual damages allegedly suffered by the record labels as the result of the sharing of the 24 recordings she was found to have distributed via KaZaA....

SYRACUSE - The water looks clear, but the label on the bottle tells a different story. "Ingredients," notes the back side of the bottle's label: "Water, fecal matter, toilet paper, hair, lint, rancid grease, stomach acid and trace amounts of Pepto Bismol, chocolate, urine, body oils, dead skin, industrial chemicals (aluminum, copper, zinc, lead, chromium, nickel, molybdenum, selenium, silver arsenic, mercury,) ammonia, ... soil, laundry soap, bath soap, shaving cream, sweat, saliva, salt, sugar. No artificial colors or preservatives. Some variations in taste and/or color may occur due to holidays, predominant cuisine preference, infiltration/inflow, or sewer cross-connections." The specially labeled...

Andy Woerner and his crazy rocketeer friends have built a 21-foot long X-Wing model that can actually fly. Yes, this is a real X-Wing powered by four solid-fuel rocket engines complete with radio-controlled moving wings. It blasts off in California next week, and we talked with Andy about the project, and how they expect it will do. All the details and a full construction gallery after the jump. The X-Wing model is huge. At 21 feet long and with a wingspan of over 19 feet it is, in fact, big enough to fly a kid in. However, knowing that it...

The Air Force completed a four-phase transition of the Global Positioning System ground segment to the new Architecture Evolution Plan on Sept. 14. AEP was delivered by the Space and Missile Systems Center's GPS Wing to the 50th Space Wing to replace the legacy 1970s-era mainframe computer at Schriever AFB, Colo. SMC managed the development, integration and test with the Boeing Company, who led a joint Boeing-Lockheed Martin contractor team, to design and build the new system. The transition was executed by the 2nd Space Operations Squadron from the 50th Space Wing and the 19th Space Operations Squadron from the...

This column is written for mainstream, nontechie users of digital technology. These folks aren’t necessarily novices, and they aren’t afraid of computers. They also aren’t stupid. They simply want their digital products to operate as promised, with as little maintenance and hassle as possible. So, I have steered away from recommending Linux, the free computer operating system that is the darling of many techies and IT managers, and a challenger to Microsoft’s dominant Windows and Apple’s resurgent Macintosh operating system, OS X. Linux, which runs on the same hardware as Windows, has always required much more technical expertise and a...

Two news items passed recently without notice in The Tribune's pages. Separately, each story is troubling enough, but put side by side, the two stories illuminate a terrifying trend. The first comes from Myanmar, formerly Burma, and tells how its military junta has created civilian gangs to solidify power by antagonizing dissent. The second comes from our own country and tells how the Bush administration has also created civilian gangs, called "rally squads," to antagonize protesters and demonstrators. These civilian volunteers stand ready to block protesters' signs and to drown out demonstrators' chants, ensuring that nary a critical word is...

A team of astronomers have taken pictures of the stars that are sharper than anything produced by the Hubble telescope, at 50 thousandths of the cost. The researchers, from the University of Cambridge and the California Institute of Technology (Caltech), used a technique called “Lucky Imaging” to take the most detailed pictures of stars and nebulae ever produced – using a camera based on the ground. Images from ground-based telescopes are usually blurred by the Earth’s atmosphere - the same effect that makes the stars appear to twinkle when we look at them with the naked eye. The Cambridge/Caltech...

Scientists at the University of Rochester and the J. Craig Venter Institute have discovered a copy of the genome of a bacterial parasite residing inside the genome of its host species. The research, reported in today's Science, also shows that lateral gene transfer—the movement of genes between unrelated species—may happen much more frequently between bacteria and multicellular organisms than scientists previously believed, posing dramatic implications for evolution. Such large-scale heritable gene transfers may allow species to acquire new genes and functions extremely quickly, says Jack Werren, a principal investigator of the study. If such genes provide new abilities in species...

The LDS Church has posted the contents of a new pamphlet about same-sex attraction on its Web site. The piece, titled "God Loveth His Children," reiterates the church's long-held distinction between same-sex attractions and actions, suggesting that only the latter are immoral. According to LDS doctrine, sexuality is only appropriate within heterosexual marriage. Everyone else is expected to be chaste. It acknowledges that some singles, homosexual and heterosexual, may never marry in this life, but "will be perfected in the next life so that every one of God's children may find joy in a family consisting of a husband, a...

"Ed," a retired spammer, built a considerable fortune sending e-mails that promoted pills, porn and casinos. At the peak of his power, Ed says he pulled in US$10,000 to US$15,000 a week, storing the money in US$20 bills in stacks of boxes. It was a life of greed and excess, one that preyed especially on vulnerable people hoping to score drugs or win money gambling on the Internet. From when he was expelled from high school at 17 until he quit his spam career at 22, Ed -- who does not reveal his full name but sometimes goes by SpammerX...

In the 40 years that humans have been traveling into space, the suits they wear have changed very little. The bulky, gas-pressurized outfits give astronauts a bubble of protection, but their significant mass and the pressure itself severely limit mobility. Dava Newman, a professor of aeronautics and astronautics and engineering systems at MIT, wants to change that. Newman is working on a sleek, advanced suit designed to allow superior mobility when humans eventually reach Mars or return to the moon. Her spandex and nylon BioSuit is not your grandfather's spacesuit--think more Spiderman, less John Glenn. Traditional bulky spacesuits "do...
