Submission + - Netflix Prize Comes To A Buzzer-Beater, Nailbiting (techcrunch.com)

suraj.sun writes: Netflix Prize Comes To A Buzzer-Beater, Nailbiting Finish

Since we reported ( http://www.techcrunch.com/2009/07/25/netflix-prize-leaders-one-upped-with-one-day-remaining/ ) on the contest last night, two teams in the Netflix Prize have spent the last few hours jumping back and forth on the Netflix leaderboard ( http://www.netflixprize.com//leaderboard ) as the three-year-long competition ticked into its final moments, with last minute sniping submissions coming from both sides.

Finally, the results are in: The Ensemble has managed to come from behind to upset BellKor's Pragmatic Chaos with a top submission of 10.10% — an improvement of .01% — only 4 minutes before the contest closed.

Last night, a team called The Ensemble managed to one-up team BelKor with a score of 10.09%, less than 24 hours before the close of the competition. BellKor was clearly still hard at work — it managed to tie the Ensemble with a score of 10.09% with only around 24 minutes remaining in the competition.

But they were to be foiled once more: with only four minutes left, The Ensemble struck back with a score of 10.10% to regain the top spot on the Netflix leaderboard. Soon thereafter a notice ( http://www.netflixprize.com/closed ) went up on the Netflix homepage stating that there were to be no more submissions.

Update: Yehuda Koren of BellKor's Pragmatic Chaos has posted ( http://www.netflixprize.com/community/viewtopic.php?pid=9237#p9237 ) on the contest's forums that BellKor came out with the lowest Test score, though it appears that Netflix has yet to confirm this.

Submission + - Could a meteor have brought down Air France 447? 1

niktemadur writes: In light of an Air Comet pilot's report to Air France, Airbus and the Spanish civil aviation authority that, during a Monday flight from Lima to Lisbon "Suddenly, we saw in the distance a strong and intense flash of white light, which followed a descending and vertical trajectory and which broke up in six seconds", the Cosmic Variance blog team on the Discover Magazine website muses on the question "What is the probability that, for all flights in history, one or more could have been downed by a meteor?". Taking into account total flight hours and the rate of meteoric activity with the requisite mass to impact on Earth (approximately 3,000 a day), some quick math suggests there may be one in twenty odds of a plane being brought down in the period from 1989 to 2009. Intriguingly, in the aftermath of TWA flight 800's crash in 1996, the New York Times published a letter by Columbia professors Charles Hailey (physics) and David Helfand (astronomy), in which they stated the odds of a meteor-airplane collision for aviation history up to that point: one in ten.

Aside from that, does swap size have to match physical RAM for hibernation, even if the machine has copious and largely unused amounts of it?

Not any more, nowadays uswsusp2 will compress (lzw?) your RAM image. Personally, i rarely get an image larger than 500MB on my laptop when hibernating.

How To Verify CD-R Data Retention Over Time? 303

Peter (Professor) Fo writes "I've recently had two CD-Rs reported to me as faulty which are just 3 years old. This is worrying — I suspect the failure rate for this batch could be 10%. When researching CD longevity there is old and unreliable information; pious 'how to cosset your discs so they last 100 years' blurb; and endless discussions of what sort of dye to use, don't use cheap media, burn slower (or don't), but not much by way of hard facts besides there's a lot of data loss going on. Does anyone know of a generic utility (win or *nix would suit me) that can map sector readability/error rates of CDs? I'd like to measure decay over time in my environment with my media and my other variables; and I expect others would too."

Comment Ok, seriously... enough with the Sept. 11 crap (Score 5, Insightful) 409

Yes, I'll probably get modded troll or something for this, but it needs saying.

There's many comments in here about "oh, what about Sept. 11... couldn't they pick a better day?" and the like.

NEWS FLASH: The rest of the world does NOT come to a screeching halt every Sept. 11th. All points of business are NOT put on hold on that one day of the year. The rest of the world has moved on, if they even stopped to begin with. GET OVER IT!

LHC isn't even located in the USA for christ sakes.

Yes, the Sept. 11 events were sad, but seriously... stop criticizing all events taking place somewhere on earth on or around that date.

Submission + - Facebook Widget Installs Zango Spyware (net-security.org)

BaCa writes: A malicious Facebook Widget actively spreading on the social networking site ultimately prompts users to install the infamous "Zango" adware/spyware. The tremendous success and lightning fast expansion of Facebook empowered the social networking giant with an impressive user base. Needless to say, in a digital world where web traffic equals money, such a user base attracts spammers, virus/spyware seeders, and other ethic-less online marketers like honey would attract flies.

Brandee07 writes: Designed for a 90 day mission, the Spirit Mars Rover is starting its 4th year of exploration. Opportunity will turn four on Jan 25. From the article: "We never thought we'd still be driving these robots all over Mars," said Mark Lemmon, a planetary scientist at Texas A&M University and member of the rover science team. "We joked about driving Opportunity into Victoria Crater, but now we're there, and we're looking at doing even more science. Each day they still work is an amazing one."

Submission + - Domains May Disappear After Search 1

Ponca City, We Love You writes: "A perfect domain name pops into your mind, a quick check at your registrar reveals that the domain is available, you put off the registration a few minutes and when you come back to register the domain, it's taken by someone else. How much time has elapsed between the search and the attempted registration — in one case, less than 90 seconds. Daily Domainer has an interesting story alleging that there may be a leak that allows domain tasters to intercept, analyze and register your domain ideas in minutes. "Every time you do a whois search with any service, you run a risk of losing your domain," says one industry insider. ICANN's Security and Stability Advisory Committee (SSAC ) has not been able to find hard evidence of Domain Name Front Running but they have issued an advisory (pdf) for people to come forward with hard evidence it is happening. Here is how domain name research theft crimes can occur and some tips to avoiding being a victim."

Submission + - Cosmic explosion detonates in empty space (newscientist.com)

mlimber writes: According to an article in NewScientist, "Astronomers are puzzling over a powerful cosmic explosion that seems to have detonated in a region of empty space, far away from any nearby galaxy." The leading theory is that the explosion was a star exploding in the gas trail that is yanked out of a galaxy when it passes or begins merging with another. Said the lead author of the study, "Even if the galaxies have stopped forming stars, in the tidal tails you can trigger new episodes of star formation [not to mention detonation]," and indeed the authors have identified two candidate galaxies that give weight to their theory.

In an attempt to gather human knowledge, Google will accept articles from users who will be credited with the article by name. If they want, they can allow ads to appear alongside the content and they will be getting a share of the profits if that's the case.

Is this a better model for free information gathering?

Submission + - Russia's New Cosmodome Approved (space.com) 1

eldavojohn writes: "You may recall discussing Baikonur, the Kazakhstan city rented by Russia that has been used as a launch site for quite sometime. Today, Putin has just approved construction of Vostochny between 2010 and 2018 which will be positioned in the far east of Russia to complement the Plesetsk Cosmodrome in the northern part of the country. This is not bad news for Kazakhstan as the director of the Russian Federal Space Agency has announced they plan to operate this facility alongside Baikonur. Is this a sign of a growing healthy space program in Russia?"
