Mediterranean Might Have Filled In Months 224

An anonymous reader writes "A new model suggests that the Mediterranean Sea was filled in a gigantic flood some 5.3 million years ago. According to Daniel Garcia-Castellanos' paper in Nature, the sill at the Straight of Gibraltar gave way rather suddenly, with 40 cm of rock eroding and the water level rising by 10 m per day at its peak. They imagine a shallow, fast-moving stream of water (around 100 km/hr) several kilometers wide pouring into the basin with a flow greater than a thousand Amazon rivers — that's about 100,000,000 cubic meters per second." The flood would have dropped worldwide sea levels by 9.5 meters, probably triggering climate changes. In this model the Mediterranean filled in anywhere from a few months to two years at the outside.

"Universal Jigsaw Puzzle" Hits Stores In Japan 241

Riktov writes "I came across this at a Tokyo toy store last week, and it's one of the coolest things I've seen in a long time. Jigazo Puzzle is a jigsaw puzzle, but you can make anything with it. It has just 300 pieces which are all just varying shades of a single color, though a few have gradations across the piece; i.e., each piece is a generic pixel. Out of the box, you can make Mona Lisa, JFK, etc, arranging it according to symbols printed on the reverse side. But here's the amazing thing: take a photo (for example, of yourself) with a cell-phone, e-mail it to the company, and they will send you back a pattern that will recreate that photo. This article is in Japanese, but as they say, a few pictures are worth a million words. And 300 pixels are worth an infinite number of pictures."

Canada Supreme Court Broadens Internet "Luring" Offense 596

An anonymous reader points out this report that a Canadian Supreme Court has broadened its interpretation of an existing law designed to punish adults who attempt to meet children online for criminal purposes; under the court's interpretation, says the article, that would now "include anyone having an inappropriate conversation with a child — even if the chats aren't sexual in nature and the accused never intended to meet the alleged victim." The story quotes Mark Hecht, of the organization Beyond Borders, thus: "If you're an adult and if you're having conversations with a child on the Internet, be warned because even if your conversations aren't sexual and even if your conversations are not for the purpose of meeting a child and committing an offence against a child, what you're doing is potentially a crime."

Trying To Bust JavaScript Out of the Browser 531

eldavojohn writes "If you think JavaScript is a crime against humanity, you might want to skip this article, because Ars is reporting on efforts to take JavaScript to the next level. With the new ECMAScript 5 draft proposal, the article points out a lot of positive things that have happened in the world of JavaScript. The article does a good job of citing some of the major problems with JavaScript and how a reborn library called CommonJS (formerly ServerJS) is addressing each of those problems. No one can deny JavaScript's usefulness on the front end of the web, but if you're a developer do you support the efforts to move it beyond that?"

Are Ad Servers Bogging Down the Web? 387

blackbearnh writes "The work of making high-volume web sites perform well is an ongoing challenge, and one that continues to evolve as the nature of web content changes. According to Google Performance Guru Steve Souders, fat JavaScript libraries and rich content are creating new problems for web site tuning, but one of the biggest problems lies outside the control of web site administrators — ad servers. In an interview previewing the upcoming Velocity Online conference run by O'Reilly, Souders talks at length about the real causes of poor web performance today, and in particular, the effect that poorly performing ad servers are creating. 'We adopted a framework of inserting ads, of creating ads, that's pretty simple. And because it's pretty simple, it's not highly tuned. That's one reason why we shouldn't be too surprised that we see performance issues in third party ads. The other reason is that ad services are not focused on technology. Certainly companies like Yahoo and Google and Microsoft, we're technology companies. We focus on technology. So it's not surprising that our web developers are on the leading edge of adopting these performance best practices. And it's also not surprising that ad services might lag two, three or four years behind where these web technology companies are.'"

NASA Willing To Team With China; Rumors of a Budget Cut 200

eldavojohn writes "2009 has been an interesting year for NASA — from a new strategy to even closer ties with an old enemy. So it's perhaps no surprise that NASA has publicly stated that they are ready to team up with China. NASA Chief Charles Bolden said, 'I am perfectly willing, if that's the direction that comes to me, to engage the Chinese in trying to make them a partner in any space endeavor. I think they're a very capable nation. They have demonstrated their capability to do something that only two other nations that have done — that is, to put humans in space. And I think that is an achievement you cannot ignore. They are a nation that is trying to really lead. If we could cooperate we would probably be better off than if we would not.' While the budget of the China National Space Administration is a fraction of NASA's, partnering with them has been considered since 2008. In possibly related news, rumors are circulating of the Obama administration cutting NASA's budget by ten percent for fiscal year 2011 despite the success of Monday's Atlantis launch. Considering the Augustine panel's recommendations, such a cut could halt US human space flight for a decade."

NASA Attempts To Assuage 2012 Fears 881

eldavojohn writes "The apocalyptic film 2012 has dominated the box office, taking in $65 million on opening weekend. But with all those uninformed eyeballs watching the film, NASA has found itself answering so many common questions that their Ask an Astrobiologist blog offers calming, professional reassurance that there is no planet Nibiru, nor will it collide with Earth (although I do recall a massive solar storm forecast). NASA's main site even offers a FAQ answering similar questions. NPR has more on NASA scientist David Morrison and his efforts to calm the ensuing public hysteria, but survivalists are already planning for the big one. Pretty funny, right? Not according to Morrison: 'I've had three from young people saying they were contemplating committing suicide. I've had two from women contemplating killing their children and themselves. I had one last week from a person who said, "I'm so scared, my only friend is my little dog. When should I put it to sleep so it won't suffer?" And I don't know how to answer those questions.'"

Rosetta Fly-By To Probe "Pioneer Anomaly" 89

DynaSoar writes "On Friday November 13th, ESA'a Rosetta probe will get its third and final gravity assist slingshot from Earth on its way to its primary targets, the asteroid Lutetia and Comet 67P/Churyumov-Gerasimenko. But the slingshot itself will allow ESA scientists to examine the trajectory for unusual changes seen in several other probes' velocities. An unaccountable variation was first noticed as excess speed in Pioneers 11 and 12, and has since been called the Pioneer Anomaly. More troubling than mere speed increase is the inconsistency of the effect. While Galileo and NEAR had appreciable speed increases, Cassini and Messenger did not. Rosetta itself gained more speed than expected from its 2005 fly-by, but only the expected amount from its 2007 fly-by. Several theories have been advanced, from mundane atmospheric drag to exotic variations on special relativity, but none are so far adequate to explain both the unexpected velocity increases and the lack of them in different instances. Armed with tracking hardware and software capable of measuring Rosetta's velocity within a few millimeters per second while it flies past at 45,000 km/hr, ESA will be gathering data which it hopes will help unravel the mystery."

The Machine SID Duplication Myth 201

toppings writes "Microsoft Technical fellow Mark Russinovich explains why he is now retiring NewSID, which has been used by IT departments for years when deploying Windows to new systems from customized clone images. Russinovich writes: 'The reason that I began considering NewSID for retirement is that, although people generally reported success with it on Windows Vista, I hadn't fully tested it myself and I got occasional reports that some Windows component would fail after NewSID was used. When I set out to look into the reports I took a step back to understand how duplicate SIDs could cause problems, a belief that I had taken on faith like everyone else. The more I thought about it, the more I became convinced that machine SID duplication — having multiple computers with the same machine SID — doesn't pose any problem, security or otherwise. I took my conclusion to the Windows security and deployment teams and no one could come up with a scenario where two systems with the same machine SID, whether in a Workgroup or a Domain, would cause an issue. At that point the decision to retire NewSID became obvious.' He concludes: 'It's a little surprising that the SID duplication issue has gone unquestioned for so long, but everyone has assumed that someone else knew exactly why it was a problem. To my chagrin, NewSID has never really done anything useful and there's no reason to miss it now that it's retired. Microsoft's official policy on SID duplication will also now change and look for Sysprep to be updated in the future to skip SID generation.'"

"Dead" Facebook User Gets Better Screenshot-sm 14

Two9A writes "With the recent introduction of memorial accounts on Facebook, the potential arises for hilarity and abuse. Simon Thulbourn's Facebook page has been marked as 'in memorial' on the word of a report submitted by one of his friends; unfortunately, the closest the report gets to Simon is that the funeral service in question was officiated by 'Revd. Simon Thorburn,' which seems to be enough for Facebook to mark an unrelated user's profile as dead. Questions have previously been raised about the standard of proof required by Facebook for this service; it seems that those questions were pertinent, if the lax attention paid to these reports by Facebook staff continues."

Facebook To Preserve Accounts of the Dead 292

Barence writes "Social-networking site Facebook is planning to preserve the accounts of dead members. The new 'memorialized' accounts will continue to display photos and wall posts, but remove 'sensitive information' such as status updates and contact information. Friends or family who want to report the death of a Facebook member are encouraged to fill out the site's Deceased form. The form asks for proof of death, such as an obituary or news article, although it's not clear how Facebook can validate the death of a member if neither of those pieces of information is published on the internet. How long before someone snuffs it on Facebook before their time?"

Volunteers Wanted For Simulated 520-Day Mars Trip 356

anglico writes 'Starting in 2010, an international crew of six will simulate a 520-day round-trip to Mars, including a 30-day stay on the martian surface. In reality, they will live and work in a sealed facility in Moscow, Russia, to investigate the psychological and medical aspects of a long-duration space mission. ESA is looking for European volunteers to take part.'

The Kindle Killer Arrives 542

GeekZilla sends coverage from Wired's Gadget Lab on the Nook, Barnes & Noble's first e-book reader. "Sleek, stylish and runs the Android OS. What's not to like about Barnes and Noble's new e-book reader? Despite the odd name, the Nook looks like an eBook reader that would actually be a worthwhile investment. Best feature? The ability to loan e-books you have downloaded to other Nook owners. The reader, named the 'Nook,' looks a lot like Amazon's white plastic e-book, only instead of the chiclet-keyboard there is a color multi-touch screen, to be used as both a keyboard or to browse books, cover-flow style. The machine runs Google's Android OS, will have wireless capability from an unspecified carrier, and comes in at the same $260 as the now rather old-fashioned-looking Kindle." Here is the B&N Nook site, which is still not visible on their front page and has a few non-working links. (Nook.com isn't set up yet.) Their comparison page takes dead aim at the Kindle. Among the advantages in the Nook's column: Wi-Fi, expandable memory via microSD, MP3 player, and PDF compatibility. (But remember the cautionary note B&N struck six years back when they got out of the e-book business.)
