vile8 writes "With the high gas prices and ongoing gas gouging in my hometown many people are trying to find a reasonable way to save gas. One of the things I've noticed is people driving exceptionally slow, 30mph in 45mph zones, etc. So I had to take a quick look and find out if driving slow is helpful in getting better mileage. I know horsepower increases substantially with wind resistance, but with charts like this one from truckandbarter.com it appears mileage is actually about the same between 27mph and 58mph or so. So I'm curious what all the drivers out there with the cool efficiency computers are getting ... of specific interest would be the hemis with MDS; how do those do with the cylinder shutoff mode at different speeds?" Related: are there any practical hypermiling techniques that you've found for people not ready to purchase a new car, nor give up driving generally?

DynaSoar writes "Esther Dyson, known to many as a founding and consistently guiding member of ICANN, and for working with the startups of Flickr, del.icio.us, Medscape and others, is now expanding her interests upwards. She recently announced that she will be heading to Moscow to train as backup astronaut for Charles Simonyi, who plans to fly aboard Soyuz TMA-14 next year. The US$3 million price tag won't be her first cash contribution towards personal space flight. She's already an investor in Space Adventures, the company that arranges the space tourist flights on Soyuz."

chromakey writes "The Wall Street Journal is running an essay from Lawrence Lessig about the fair use of copyrighted material on the Internet. He makes the case that companies who go to extreme lengths to squash minor videos, such as Universal, are stifling creativity in the modern era. Lessig makes specific reference to a YouTube video that was hit by a DMCA takedown notice, in which a 13-month-old child is dancing to a nearly inaudible soundtrack of Prince's 'Let's Go Crazy.' Lawrence Lessig is a board member for the Electronic Frontier Foundation."

Vigile writes "With the news that Apple will be releasing new MacBook products on October 14th, speculation has begun on what exactly those new products will be. Tips of a manufacturing process involving lasers and a single 'brick' of aluminum are catching on, as is the idea of a sub-$1000 netbook-type device. More interesting might be the persistent rumors of an NVIDIA chipset adoption that would drastically increase gaming ability, allow MacBooks to improve their support for OpenCL and take advantage of the new Adobe CS4 software with GPU acceleration. Will NVIDIA's ailing chipset business get a shot in the arm next week?"

GogglesPisano writes "UK geneticist Steve Jones gave a presentation entitled Human Evolution Is Over. He asserts that human beings have stopped evolving because modern social customs have lowered the age at which human males have offspring, which results in fewer of the mutations necessary to drive evolutionary change. Apparently the fate of our species now depends upon older guys hooking up with younger woman. I, for one, welcome this development."

radioweather writes "A recently discovered Apollo Asteroid, 2008 TC3, exploded over Sudan at about 1046 EDT on October 7, 2008, according to astronomer Tim Spahr of Harvard University 2008 TC3 was discovered on Monday by an observer at the Mt Lemmon Observatory near Tucson, Arizona. 2008 TC3 is notable in that it is the first Asteroid of its size that was identified before impact and tracking it put the entire Spaceguard tracking system to an extreme test. TC3 is estimated to be only two to five meters in diameter but exploded with the force of a one kiloton of explosive power." We mentioned the asteroid last on Monday, when it was only at a 99.8 percent chance of colliding with Earth.

CR0WTR0B0T writes "Richard Garriott, AKA Lord British, will be part of three experiments on the International Space Station. 'Garriott has a ticket to the space station because he is an orbital spaceflight client of Space Adventures, the only company that provides commercial human space missions ... Garriott will be the first person in space who has had photorefractive keratectomy eye surgery. NASA has approved the PRK procedure for astronauts but has not yet been able to test its effects. Garriott will help scientists figure out if visual acuity of a PRK patient changes in orbit as inner eye pressure increases by up to 50% during space flights.' Mostly, NASA wants to know if he can heal himself or provide resurrection to the other astronauts in case the experiments goes awry."

John Sokol writes "I just heard from a good friend and Linux kernel hacker in Brazil that they have just finished their municipal election with 128 million people using Linux to vote. They voted nationwide for something like 5,000 city mayors. Voting is mandatory in Brazil. The embedded computer they are using once ran VirtuOS (a variant of MS-DOS); it now has its own locally developed, Linux-based distro. These are much nicer, smaller, and cheaper than the systems being deployed here in the US. Here is a Java-required site with a simulated Brazilian voting system. It's very cool; they even show you a picture of the candidate you voted for."

thesandbender writes "Ford is set to release a management system that will restrict certain aspects of a car's performance based on which key is in the ignition. The speed is limited to 80, you can't turn off traction control, and you can't turn the stereo up to eleven. It's targeted at parents of teenagers and seems like a generally good idea, especially if you get a break on your insurance." The keys will be introduced with the 2010 Focus coupe and will quickly spread to Ford's entire lineup.

musatov writes "There's talk on The Minor Planet Mailing List about a small asteroid approaching Earth with a 99.8% probability of colliding. The entrance to the Earth's atmosphere will take place October 7 at 0246 UTC (2:35 after this story goes live) over northern Sudan, releasing the energy of about a kiloton of TNT. The asteroid is assumed to be 3-4 meters in size; it is expected to burn up completely in the atmosphere, causing no harm. As a powerful bolide, it may put on quite a show in the sky. For those advanced enough in astronomy to observe, check the MPEC 2008-T50 and MPEC 2008-T64 circulars. NASA's JPL Small Body Database has a 3D orbit view. The story has been already picked up by CNN and NASA."

Science News reports on a paper to be published in Physical Review Letters in which an international team of researchers describes their computer simulation of the most violent collision imaginable: two black holes colliding head-on at nearly light-speed. Even in this extreme scenario, Roger Penrose's weak cosmic censorship hypothesis seems to hold — the resulting black hole (after the gravitational waves have died down) retains its event horizon. "Mathematically, 'naked' singularities, or those without event horizons, can exist, but physicists wouldn't know what to make of them. All known mechanisms for the formation of singularities also create an event horizon, and Penrose conjectured that there must be some physical principle — a 'cosmic censor' — that forbids singularity nakedness ..."

slapout writes "Weird Al has announced that with the Internet he can now release his songs for sale as he records each one rather than waiting for a whole album to be produced."

steveit_is writes "Yesterday it was reported that Microsoft's revised CAPTCHA had been cracked. Now it's Google's turn. In a move that is sure to surprise no one, the spammers behind 'Xrumer' have announced that they've not only cracked Google's CAPTCHA, but other forms of image verification as well, including 'pick the cat' style CAPTCHA."

ChazeFroy writes "A new study estimates that the AIDS virus, HIV, started to circulate in the human population between 1884 and 1924, with a more focused estimate at 1908. This is much earlier than the previously-held estimate of 1930. 'The new result is "not a monumental shift, but it means the virus was circulating under our radar even longer than we knew," says Michael Worobey of the University of Arizona, an author of the new work.' The article also speculates that HIV first began to spread in Kinshasa, Congo."

An anonymous reader writes "Cameron Freer, an instructor in pure mathematics at MIT, is working on an intriguing project called vdash.org (video from O'Reilly Ignite Boston 4): a math wiki which only allows true theorems to be added! Based on Isabelle, a free-software theorem prover, the wiki will state all of known mathematics in a machine-readable language and verify all theorems for correctness, thus providing a knowledge base for interactive proof assistants. In addition to its benefits for education and research, such a project could reveal undiscovered connections between fields of mathematics, thus advancing some fields with no further work being necessary."

GMGruman writes "Carriers have promised WiMax networks for years. But will they deliver the goods, or be slow like many early 3G networks or patchy in coverage like the metro Wi-Fi attempts in most cities? This hands-on review looks at a nearly-WiMax deployment (technically, OFDM) in Reno, testing its speeds and reach, as a measure of what Sprint and Clearwire will deliver in their joint WiMax rollouts starting next month. The good news is that this time, the carrier promises look to be delivered on."

rrohbeck writes "The Independent reports brand-new results of high concentrations of methane — 100x normal — above the sea surface over the Siberian continental shelf. A large number of methane plumes have been discovered bubbling up from the sea floor. This is probably due to methane clathrate, buried under the sea floor before the last ice age, breaking up as higher water temperatures melt the permafrost that had contained it."

xp65 writes with the just-announced success of Elon Musk's SpaceX's long efforts to reach orbit with a privately-developed launching craft: "T+0:08:21 Falcon 1 reached orbital velocity, 5200 m/s Nominal Second stage cut off (SECO) — Falcon 1 has made history as the first privately developed liquid fueled launch vehicle to achieve earth orbit!" dbullard adds "This was a completely new vehicle — it's not using any previously developed hardware. All developed from scratch. No government supplied hardware, Russian engines, or old ICBM motors. My hat's off to the employees of Space X — all 550 of them. (Note — no 'cast of thousands,' just 550). They've got video of the entire launch."

Davide Marney writes "As reported by the Washington Post, Google co-founder Larry Page claims that an FCC field test of white space wireless devices was 'rigged' to make the test device fail to detect wireless microphone broadcasts. A Google spokesman explained later that testers had hidden the wireless microphones within the same frequency as local television stations, preventing the test device from detecting them."

thhamm writes "The GNOME community hopes to make our users happy with many new features and improvements, as well as the huge number of bug fixes that are shipped in this latest GNOME release! Well. What else to say. I am happy." Notably, this release is also the occasion for the announcement of videoconferencing app Ekiga's 3.0 release.

The ever-growing unrest caused by the DRM involved with EA's launch of Spore came to a head on Monday. A woman named Melissa Thomas filed a class-action lawsuit against EA for their inclusion of the SecuROM copy-protection software with Spore. This comes after protests of the game's DRM ranged from a bombardment of poor Amazon reviews to in-game designs decrying EA and its policies. Some of those policies were eased, but EA has also threatened to ban players for even discussing SecuROM on their forums. The court documents (PDF) allege: "What purchasers are not told is that, included in the purchase, installation, and operation of Spore is a second, undisclosed program. The name of the second program is SecuROM ... Consumers are given no control, rights, or options over SecuROM. ... Electronic Arts intentionally did not disclose to any such purchasers that the Spore game disk also possessed a second, hidden program which secretly installed to the command and control center of the computer."

TheSpoom writes "Large Chicago law firm Jones Day are suing internet startup BlockShopper over the issue of whether linking to a business with their trademarked name should be legal. It would seem they are using trademark dilution as a tool to get BlockShopper to cease linking to their website. The EFF has filed an amicus curiae, as might be expected. If Jones Day wins this suit, anyone linking using a trademarked name may be in legal hot water."

thefanboy writes "What do you get when you cross BackTrack Linux apps with a mobile phone? This is the first ever publicly available mobile phone running a full custom Linux network auditing distribution, and it runs it surprisingly well. One can literally go from phone to pwn in 2 seconds. Based off of the Openmoko Neo Freerunner, many steps have been taken to compensate for the lack of a QWERTY keyboard with automation scripts, dialogs, and a point-and-pwn menu. It runs applications such as Metasploit and the Aircrack suite quite well, especially given the fact that it supports a wide array of USB WLAN cards."

Yannis B. writes "This week, a group of leading technology vendors that includes Cisco, Sun, Ericsson, Atmel, Freescale, and embedded open source developers, founded the Internet Protocol for Smart Objects Alliance to promote the 'Internet of Things,' in which everyday objects such as thermometers, radiators, and light switches are given IP addresses and are connected to the Internet. Such IP-enabled 'smart objects' give rise to a wide range of applications, from energy-efficient homes and offices to factory equipment maintenance and hospital patient monitoring. For Slashdot readers who are interested in the underlying technology, a white paper written by well-known embedded open source developer Adam Dunkels and IETF ROLL working group chair JP Vasseur establishes the technical basis of the alliance (PDF)."

gyrogeerloose writes "Stephen Hawking unveiled an unsettling clock in Cambridge on Friday. Designed by John Taylor — a British horologist and inventor whose thermostatic switch is incorporated in millions of electric appliances worldwide — the clock was conceived as a tribute to another British inventor, John Harrison. Harrison invented the grasshopper escapement in the early 18th Century, which resulted in extremely accurate mechanical time keeping and was instrumental in solving the Longitude Problem. Taylor's clock, which in entirely mechanical in operation but has no hands, uses a fearsome-looking 'demon grasshopper' as its escapement. 'I... wanted to depict that time is a destroyer — once a minute is gone you can't get it back' Taylor said. 'That's why my grasshopper is not a Disney character. He is a ferocious beast that over the seconds has his tongue lolling out, his jaws opening, then on the 59th second he gulps down time.' It also (purposely) only tells correct time once every five minutes. An excellent video of the clock in action, with an explanation of its workings by its inventor, is available on YouTube."

Earyauteur writes "The Unofficial Apple Weblog (TUAW) is running a story on an interesting motion-controlled iPhone application which uses the iPhone's 3-axis accelerometer to control a digital synthesizer. The musical instrument is played much like a theremin with the added ability to perform music using different musical scales. TUAW also links to a YouTube video which shows a performer demonstrating the iPhone instrument."

Bennett Haselton contributes the following essay on the consequences of license choice as it applies to sites based on user contributions; read on below for more of his big idea for making Knol a more useful resource. "Google Knol should allow its writers to publish under a Creative Commons Share Alike license. The preceding sentence may not mean much to you, but if you've ever wanted to cite a Wikipedia article as a source, or simply read a Wikipedia article with some assurance that someone wasn't pulling your leg with some creative editing, or if you've wanted to contribute to Wikipedia but couldn't afford the time unless you received some modest compensation for it, then the addition of this one simple feature to Knol might make all the difference." (More below.)

I've been suggesting for some time that Wikipedia, or some fork of Wikipedia, should allow users to "sign off" on a version of an article, and then lock that article against future edits until the signer had approved them. The signing off would allow people to cite a Wikipedia article as a source that had been vetted by at least one person (with confidence in the source depending on that person's credentials). The signer's identity (and sometimes, their credentials) could be confirmed using several methods, such as verifying an .edu e-mail address. Users could still submit edits, but they would have to be approved by the article verifier. Different users could sign off on different versions of the same article, and readers would still have the option of viewing the latest version of an article, with all of its unmoderated edits (which is what you're looking at on Wikipedia most of the time).

Knol, which allows users to submit articles on any topic they want, has incorporated all of the above features (adding, for example, the ability to verify authors' real names using credit cards), and gone one step further by allowing users to place AdSense ads in their articles. However, there's one stumbling block to Knol incorporating all of Wikipedia's content and blessing it with the verification of credentialed experts: Currently, although you have to dig a bit deep to find this out, Knol's Terms of Service do not allow content to be copied from Wikipedia.

Content on Wikipedia is published under the GNU Free Documentation License -- when you click any of the "edit" links in a Wikipedia article and begin typing in new content, you're agreeing to submit your content under the terms of the GFDL. When you publish on Knol, on the other hand, your options are to publish under a Creative Commons Attribution 3.0 License (CC-BY), a Creative Commons Attribution-Noncommercial 3.0 License (CC-BY-NC), or a traditional "All Rights Reserved" copyright model. Both the GFDL and the Creative Commons Attribution licenses are popular with content creators who want to give content altruistically "to the world" -- these licenses all allow content to be redistributed freely without modification. The main difference is in the rights that they grant to people who want to create derivative works (modifying or expanding on the original work).

The GFDL is intended as a "viral" license -- if you take a work that is published under the GFDL, and publish a derivative work created from that, your derivative work must also be published under the terms of the GFDL -- that is, also allowing other users to redistribute your work freely and create derivative works from it as well. If a site mirrors Wikipedia articles without including the terms of the GFDL, Wikipedia encourages users to send notifications to those sites pointing out that they're violating Wikipedia's copyright, and if necessary to escalate the matter to their Web hosting provider for noncompliance. You can mirror Wikipedia all you want, and even put put ads all over your mirror site, but you cannot change the terms.

Creative Commons Attribution (CC-BY) licenses, on the other hand, allow users to create derivative works and publish them under almost any terms they want, including an "All rights reserved" model, provided that they give attribution to the author of the original work. If Susan publishes an article under CC-BY, you can create a derivative work by expanding on her article, and -- assuming your contributions are substantial enough to be copyrightable in themselves -- you can prohibit other users from redistributing your article or creating derivative works from it, something that would not be possible if Susan had published her article under the GFDL. (Obviously, you cannot prohibit others from redistributing Susan's article or creating their own derivative works from it, but you can restrict these rights as applied to your own derivative work.)

Russell Potter, a Professor of English at Rhode Island College and a Citizendium contributor who explained this difference to me, points out that CC-BY licenses are more friendly to academics who want to reuse content in a published book or in a conference presentation. "Say an academic (me) contributes a long article on London's Crystal Palace," he wrote. "Others edit it in modest ways, but the article is still about 90% my own work. Perhaps I want to give a paper at a conference based on this entry, or use large bits of it in a book I'm writing. GFDL would have made either impossible." (Impossible, that is, unless the book publisher released the book under the GFDL, but most book publishing companies are reluctant to do that.)

And therein lies the logical incompatibility between the GFDL and the CC-BY publishing options currently allowed by Knol. If you copy GFDL-licensed content from Wikipedia, you are agreeing that for any copies or derivative works that you create, you will not only permit other users to remix them, but that you will require those other users to agree to the same terms for the remixed works that they publish. If you published such content on Knol under the CC-BY option, you would be granting the reader permission to incorporate the work into their own derivative work which they could then publish under an All Rights Reserved license. And the GFDL doesn't allow you to grant that permission to the reader. Section 5.5 of Knol's Terms of Service explicitly states that GFDL content cannot be re-published under a CC-BY license, and Mike Linksvayer makes this point on the Creative Commons blog as well. Some authors have begun copying Wikipedia content to Knol anyway, and even though that particular article included a link to the GFDL, users have pointed out in the comments that it's still a TOS violation anyway. Google appears to be lax about policing these violations for now, but in the right-hand column, the links to "Similar Content on the Web" show that Google can trivially detect if content is copied from other sites, and may be planning to remove such content or demote it in search results if it's copied from a site like Wikipedia that doesn't allow copying under Knol's terms.

However, the Creative Commons family of licenses also includes the Creative Commons Attribution-Share Alike License (CC-BY-SA), which is written in the same spirit as the GFDL -- if a work is released under CC-BY-SA, any published derivative works created from that work must also be released under the same license. In fact the Free Software Foundation, which writes new versions of the GFDL, announced in December 2007 their intention to make the next version of the GFDL explicitly compatible with CC-BY-SA, so that any work published under the GFDL can be incorporated into a work published under CC-BY-SA, and vice versa. This new version of the GFDL has not been released yet, but the FSF replied by e-mail to say they're working on it.

(Perhaps you might be wondering, as I did, how already-existing content on Wikipedia can be said to be "licensed" under a new version of the GFDL when it comes out. How can past Wikipedia contributors have agreed to a future version of the license that didn't exist yet? The answer is that when you submit edits on Wikipedia, you're agreeing to submit your edits under the "GNU Free Documentation License, Version 1.2 or any later version", and it's the "or any later version" that means contributors are deemed to have agreed to the next version of the GFDL, which will presumably be CC-BY-SA-compatible.)

If Google Knol adds the ability to publish under a Creative Commons Attribution-Share Alike license, and the FSF releases a new version of the GFDL that is compatible with this license, then I think we will finally see what I hoped for in February 2008 -- a "gold rush" of users copying content from Wikipedia to Knol, where it can be verified by credentialed users and protected against vandalism. Some users' verifications will be more valuable than others -- a physics article verified by a physics professor is more trustworthy than the same article verified by an anonymous user, and even an article about The X-Files may be more trustworthy when it's verified by a physics professor, not because it's the professor's area of expertise, but because a professor with a valued reputation would be less likely to sign their name to unverified garbage.

Will Knol add the Share Alike option? Perhaps they may be nervous about what would happen if they allowed unlimited copying from Wikipedia, especially with financial incentives. At the moment, Knol seems to be downplaying the fact that you can make money from writing articles, even as everyone else buzzes about it. On their front page, under "Learn More", Knol lists the reasons you should contribute: "Visibility - We value and promote authorship. Great content will be visible on any search engine. Community - You can connect with other experts in your area of interest to share and grow knowledge," etc. Really? That's all? AdSense isn't mentioned in the FAQ, and only briefly at the end of a posting about "Knol bugs and workarounds". And officially the site never mentions Wikipedia at all, except in the knols about it.

But many of the articles on Wikipedia -- especially the kind of articles that academics would be willing to sign their names to -- would probably enhance the Knol site, not drag it down. Wikipedia founder Jimmy Wales correctly predicted that Knol would generate a lot of articles about Viagra. If Knol can tolerate that garbage (and under their own policies, there is little grounds for removing those articles, unless the authors lifted the content from some other site), they should welcome the addition of articles about stochiometry, Shakespeare, and Serbia, even if they were copied from Wikipedia and then vetted by a university professor or journalist. (None of those topics have their own Knol yet, although there was room for Knols about Simon Cowell, Superman, and sex addiction.)

After all, the incentives that AdSense creates for Knol writers are roughly the same as the incentives for Web publishers in general -- you can try to turn a quick buck, or you can invest in your site's reputation for the long run -- and while there is a new "made-for-AdSense" site born every minute, few would disagree that the rise of AdSense has been good for content on the Web in general.

While copying from Wikipedia to Knol is against the rules right now, there's no reason in principle to be against creating a Wikipedia sub-fork on Knol, if Google allows Knol writers to select the Creative Commons Attribution-Share Alike publishing option. One user, responding to the unauthorized use of Wikipedia articles, posted in the Knol users' group on Google Groups: "What I REALLY want to see Google do is crack down on these clowns who are copying and pasting articles from Wikipedia." I say, just change the rules and send in the clowns.

Some authors have begun copying Wikipedia content to Knol anyway, and even though that particular article included a link to the GFDL, users have pointed out in the comments that it's still a TOS violation anyway. Google appears to be lax about policing these violations for now, but in the right-hand column, the links to "Similar Content on the Web" show that Google can trivially detect if content is copied from other sites, and may be planning to remove such content or demote it in search results if it's copied from a site like Wikipedia that doesn't allow copying under Knol's terms.

However, the Creative Commons family of licenses also includes the Creative Commons Attribution-Share Alike License (CC-BY-SA), which is written in the same spirit as the GFDL -- if a work is released under CC-BY-SA, any published derivative works created from that work must also be released under the same license. In fact the Free Software Foundation, which writes new versions of the GFDL, announced in December 2007 their intention to make the next version of the GFDL explicitly compatible with CC-BY-SA, so that any work published under the GFDL can be incorporated into a work published under CC-BY-SA, and vice versa. This new version of the GFDL has not been released yet, but the FSF replied by e-mail to say they're working on it.

(Perhaps you might be wondering, as I did, how already-existing content on Wikipedia can be said to be "licensed" under a new version of the GFDL when it comes out. How can past Wikipedia contributors have agreed to a future version of the license that didn't exist yet? The answer is that when you submit edits on Wikipedia, you're agreeing to submit your edits under the "GNU Free Documentation License, Version 1.2 or any later version", and it's the "or any later version" that means contributors are deemed to have agreed to the next version of the GFDL, which will presumably be CC-BY-SA-compatible.)

If Google Knol adds the ability to publish under a Creative Commons Attribution-Share Alike license, and the FSF releases a new version of the GFDL that is compatible with this license, then I think we will finally see what I hoped for in February 2008 -- a "gold rush" of users copying content from Wikipedia to Knol, where it can be verified by credentialed users and protected against vandalism. Some users' verifications will be more valuable than others -- a physics article verified by a physics professor is more trustworthy than the same article verified by an anonymous user, and even an article about The X-Files may be more trustworthy when it's verified by a physics professor, not because it's the professor's area of expertise, but because a professor with a valued reputation would be less likely to sign their name to unverified garbage.

Will Knol add the Share Alike option? Perhaps they may be nervous about what would happen if they allowed unlimited copying from Wikipedia, especially with financial incentives. At the moment, Knol seems to be downplaying the fact that you can make money from writing articles, even as everyone else buzzes about it. On their front page, under "Learn More", Knol lists the reasons you should contribute: "Visibility - We value and promote authorship. Great content will be visible on any search engine. Community - You can connect with other experts in your area of interest to share and grow knowledge," etc. Really? That's all? AdSense isn't mentioned in the FAQ, and only briefly at the end of a posting about "Knol bugs and workarounds". And officially the site never mentions Wikipedia at all, except in the knols about it.

But many of the articles on Wikipedia -- especially the kind of articles that academics would be willing to sign their names to -- would probably enhance the Knol site, not drag it down. Wikipedia founder Jimmy Wales correctly predicted that Knol would generate a lot of articles about Viagra. If Knol can tolerate that garbage (and under their own policies, there is little grounds for removing those articles, unless the authors lifted the content from some other site), they should welcome the addition of articles about stochiometry, Shakespeare, and Serbia, even if they were copied from Wikipedia and then vetted by a university professor or journalist. (None of those topics have their own Knol yet, although there was room for Knols about Simon Cowell, Superman, and sex addiction.)

After all, the incentives that AdSense creates for Knol writers are roughly the same as the incentives for Web publishers in general -- you can try to turn a quick buck, or you can invest in your site's reputation for the long run -- and while there is a new "made-for-AdSense" site born every minute, few would disagree that the rise of AdSense has been good for content on the Web in general.

While copying from Wikipedia to Knol is against the rules right now, there's no reason in principle to be against creating a Wikipedia sub-fork on Knol, if Google allows Knol writers to select the Creative Commons Attribution-Share Alike publishing option. One user, responding to the unauthorized use of Wikipedia articles, posted in the Knol users' group on Google Groups: "What I REALLY want to see Google do is crack down on these clowns who are copying and pasting articles from Wikipedia." I say, just change the rules and send in the clowns.

Now, though, there are binaries available for download through the XBMC Media Center site, though only for the non-Xbox versions.

Kligat writes "The International Astronomical Union has renamed the dwarf planet Haumea and its two moons Hi'iaka and Namaka, after the Hawaiian fertility goddess, the patron goddess of Hawaii, and a water spirit. The cigar-shaped body is speculated to have resulted from its short rotational period of only four hours. Holding up the reclassification of the body as a dwarf planet was a dispute over its discovery between the groups of José Luis Ortiz Moreno and Michael E. Brown."

hackingbear writes "According to a report by Hong Kong newspaper Mingpao Daily (poor Google translation), quoting the Director of Jiuquan Launch Center, China is set to build a space station by snapping together four spaceships (Shenzhou 7, 8, 9, and 10), to be launched sequentially. Though other reports indicates that taikonauts abroad SZ 7 will return to Earth on September 28, the official said the ship will remain in the orbit to be docked with unmanned Shenzhou 8 and 9. Finally, the manned spaceship Shenzhou 10 will be launched and dock with the other three, completing the space station." A story at Space.com also briefly mentions Shenzhous 8 and 9 (with no mention of number 10), and adds that China has selected its first spacewalker.

Hugh Pickens writes "Researchers at the University of Texas at Austin have achieved a breakthrough in the use of a one-atom thick graphene for storing electrical charge in ultracapacitors. They believe their development shows promise that graphene could eventually double the capacity of existing ultracapacitors. 'Through such a device, electrical charge can be rapidly stored on the graphene sheets, and released from them as well for the delivery of electrical current and, thus, electrical power,' says one of the researchers. Two main methods exist to store electrical energy: in rechargeable batteries and in ultracapacitors, which are becoming increasingly commercialized but are not yet well known to the public. Some advantages of ultracapacitors over traditional energy storage devices such as batteries include: higher power capability, longer life, a wider thermal operating range, lighter, more flexible packaging and lower maintenance. Graphene has a surface area of 2,630 square meters, almost the area of a football field, per gram of material."

Kaseijin writes "Neuroscientist Champadi Raman Mukundan claims his Brain Electrical Oscillations Signature test is so accurate, it can tell whether a person committed or only witnessed an act. In June, an Indian judge agreed, using BEOS to find a woman guilty of killing her former fiancé. Scientific experts are calling the decision 'ridiculous' and 'unconscionable,' protesting that Mukundan's work has not even been peer reviewed. How reliable should a test have to be, when eyewitnesses are notoriously fallible? Does a person have a right to privacy over their own memories, or should society's interest in holding criminals accountable come first?"

TRS-80 writes "Users of the upcoming Ubuntu release, Intrepid Ibex, are being confronted with an EULA the first time they launch Firefox. Mark Shuttleworth says 'Mozilla Corp asked that this be added in order for us to continue to call the browser Firefox... I would not consider an EULA as a best practice. It's unfortunate that Mozilla feels this is absolutely necessary' and notes there's an unbranded 'abrowser' package available. Many of the comments say Ubuntu should ditch Firefox as this makes it clear it's not Free Software, hence unsuitable for Ubuntu main, and just ship Iceweasel or Epiphany, the GNOME browser." A few comments take Canonical to task for agreeing to Mozilla's demand to display an EULA without consulting the community.

aqui writes "A university student at Carleton is learning that no good deed goes unpunished. After hacking into what was probably a not-so-secure university network, this guy took the time to write a 16-page paper on his methods and sent it to the system admins. Sounds like White Hat behavior to me. Yes, he should have asked permission before trying, but throwing the book at the guy and wrecking his life with criminal charges (which stick for a long time) seems a little excessive. The university should spend money on hiring some admins with better computer skills and teaching skills rather than paying lawyers. In the Engineering department at my old university, the unofficial policy was that when you broke in, didn't damage anything, and reported the problem and how you broke in, they didn't charge you (if you maliciously caused damage, you usually faced academic sanctions). In some cases, the students were hired or they 'volunteered' for the summer to help secure the servers or fix the hole they found. The result was that Engineering ended up with one of the most secure systems in the university." Read on for the rest of aqui's comments. aqui continues: "The truth is, some university students are going to have the desire to hack something, and not all of them have the judgment to stay out of trouble. If you acknowledge that and catch them inside the university, you can straighten them out before they wreck their lives, and teach them to be white hats. Rather than creating a hostile environment where people may become black hats, you create an environment where you guide them in the right direction to being good computer security professionals. For every hacker they catch, there's probably at least one that they don't know about. I can imagine that a number of those hackers at Carleton are now seeing the university as the enemy for burning 'one of their own,' and some of them may become malicious to get even. If the student's intentions were good - which they appear to be - I can't help but feel sorry for the guy."

Adam Korbitz writes "New Scientist and Science Daily are reporting the results of an intriguing experiment in which scientists launched tardigrades or 'water bears' — tiny invertebrates about one millimeter long — into space onboard the European Space Agency's FOTON-M3 spacecraft. After 10 days in the vacuum of space, the satellite returned to Earth and the tardigrades were recovered. The tardigrades survived the vacuum just fine, but exposure to the Sun's ultraviolet radiation proved deadly for most of the water bears. However, some did survive. The tardigrades are the first animals to have survived such an experiment, a feat previously achieved only by lichens and bacteria."

palegray.net writes "Nature is reporting on new findings that prions jump species barriers. Believed to be responsible for ailments such as Creutzfeld-Jakob disease and 'mad cow' disease, prions are thought to disrupt biological processes by causing normal proteins to fold abnormally. Researchers at the University of Texas Medical Branch in Galveston have observed infectious prions from hamsters causing abnormal protein development in mice, along with a range of other observations on prion actions in test tube environments. From the article: '... they also found that when a prion jumps species, it produces a new kind of prion. "This is very worrisome," says Claudio Soto, who led the research, published in Cell. "The universe of possible prions could be much larger than we thought."' Sounds like another good reason to donate your spare CPU cycles to projects like Folding@home."

rm writes "Internet search and mail provider Yandex, which many view to be Google's main competitor in Russia, has recently added an instant messaging capability to its mail notifier application Ya.Online. As it turns out, the IM service is based on the open XMPP protocol, with connectivity to all other public Jabber servers available from day one. MacOS X and GNU/Linux versions of the app were also released (complete with sources under the GPL) and are determined to be based on the Psi IM client. Yandex looks to be a firm believer in open-source, also running a mirror site for FOSS and actively promoting its branded version of Firefox. Here's hoping that its affair with XMPP will help eliminate ICQ's enormous foothold in Russia."

Riding with Robots writes "Yesterday the robotic spacecraft Rosetta, on its way to a distant encounter with Comet Churyumov-Gerasimenko, flew by the asteroid 'Steins,' which is roughly 4.6 kilometers wide. Steins is one of the relatively rare E-type asteroids. The mission team live-blogged throughout the day, and a press conference with the first pictures will be available soon." Rosetta's flyby took it to within 800 kilometers of Steins while both objects were roughly 360 million kilometers from Earth. According to Rosetta's fact sheet (PDF), the craft will next swing by Earth in 2009 and take a look at another asteroid in 2010 on its way to the rendezvous with the comet in 2014.

An anonymous reader writes "Like the previous Bill C-60 before it, the proposed Bill C-61 that would bring DMCA-like laws to Canada is poised to die on the order table, never to receive a vote, as the current minority government falls. An election call is expected in days. Everybody expects that some form of these laws will be back yet again (third time's a charm?). There are too many interests pushing for change to let it go. But here's a chance for Canadians to influence politicians about it in an election campaign, and hopefully strike a better balance. And for those of you in the rest of the world who are laboring under a DMCA-like copyright law, let's hear your stories about why such laws are a good or bad idea, and if bad, how you would amend the law to make it tolerable. With the polls probably on Oct. 14th, Canadians will be looking for a few good ideas."
