An anonymous reader writes "This article claims OSX's share of the OS market is up to 7.57%, up from 7.31% a year earlier (linux also gained a bit of ground, from 0.63% to 0.67%). But the statistics were gathered by monitoring web traffic from the server side, so this doesn't take into account OSX users who are using Windows in VMWare, Parallels, or Boot Camp at the time. Another article predicts that OSX will have 12% of the OS market by 2011. Could they be there already? What is OSX's real share of the market? How could this be measured more accurately?"

There's an interesting story up at Nature News about scientific ethics. It seems that while one group of scientists is figuring out details about aetosaurs (ancient crocodiles), another group in New Mexico is repeatedly taking credit for their work and naming the new animals they discover. It also looks like the state government, which has been asked to intervene, is trying to sidestep the issue. How widespread is this kind of thing?

mykevelli writes "Following up Friday's article about a student being expelled for writing a 'threatening' photo description on Facebook, it seems once the pressure of a lawsuit backed by FIRE (Foundation for Individual Rights in Education) came against the Board of Regents, they have backed down. Barnes claims that proper disciplinary processes were not followed for his expulsion and is also asking reimbursement for expenses associated with moving to another university and enrolling there for one semester. Yesterday, the Board of Regents reversed the expulsion of Hayden Barnes. It is unknown at this time whether or not Barnes plans to re-enroll and continue at VSU."

rah1420 writes "According to a recent sidebar in the NY Times, a couple of federal appeals courts have upheld the right of the government to inspect the hard drive contents of any hard drive entering the US. So make sure you leave the pr0n at home. And your finances. And your personal correspondence. And your notes and contact list (if you're a reporter.) For my part, I am buying another hard disk. I'll just install Ubuntu and Firefox and use that if I have to travel abroad."

Eric Powell writes "Archaeologists used X-Ray fluorescence spectrometer analysis to show that some "rock art" in Wyoming was actually created by sheep. Ewes marked with different colors for breeding purposes seem to have taken shelter at a rock art site, leaving behind abstract smears mistaken by archaeologists for prehistoric paintings."

s31523 writes "New speculation based on updated computer models predict a possibility of an ice free Arctic Ocean by the year 2013. As new reports come out, many scientists are saying the Arctic is screaming and we have to act fast, while others are not so sure. But with record breaking events like a record amount of surface ice was lost over Greenland this year, 12 percent more than the previous worst year, 2005, the evidence is mounting."

erpbridge writes "While recently doing a consulting job for a local college, I was asked an interesting question. They have a backend archive of videos, ranging from training to classroom instruction videos, in AVI format using DIVX codec, with an average size of about 400MB. They can easily make these videos available on campus, but for commuting students accessing from home this is not feasible. The idea is to setup a Youtube/DailyMotion style site with Flash videos. As these are to be allowed to students only, it is not feasible to upload these to a commercial site such as Youtube or DailyMotion. They don't want to transcode the entire library to ASF for Windows Media Server, and double storage capacity (same goes for transcoding all videos to FLV). They also want to keep the originals available to students onsite, as they are higher quality than any FLV will be. Instead, click a video, the backend server performs an on-the-fly FLV transcoding on demand, and the user gets the video. The temporary videos would then be cleaned up later by a collection process running on a regular basis. Has anyone seen a solution that would let a web user do this sort of on demand, on the fly FLV transcoding?"

An anonymous reader writes "Most sources of synchrotron radiation are giant dough nut-shaped particle accelerators. But researchers at the University of Strathclyde in Scotland have developed a compact synchrotron machine that could fit inside any lab. Instead of a giant ring of magnets and microwave cavities, the device uses plasma wakefield acceleration to accelerate electrons. Synchrotron radiation can be used to probe many kinds of matter and is used in many areas of scientific research."

Horar writes "From the article: One of the world's leading economists has issued a scathing denunciation of American consumerism, saying overspending could lead to a "catastrophic" recession... He says the United States has a current account deficit of $US811 billion for last year, which means America is borrowing [more than two] billion a day from overseas.

What are the implications of this for the IT industry if there is such a recession? Alternatively, what would happen if rampant consumerism is brought under control? Isn't it that very consumerism that pushes the development of the devices and technologies which most slashdotters could not live without?"

The highly respected palaeontology journal Acta Palaeontologica Polonica has published its December number for free access on the web, with the headline paper concerning new discoveries of dinosaurs from Antarctica.

The first major part of these discoveries were made as isolated bones of a sauropod (a relative of the well-known Brontosaurus) which were associated with a theropod (ancestor or cousin of Tyrannosaurus rex). These specimens were discovered at an altitude of 4100m, above the Beardmore Glacier in the TransAntarctic Mountains in 1991. Further field work during the following 13 years produced more material, seemingly from the same specimens and allowed more accurate description of the sauropod and it's naming as Glacialisaurus hammeri (the reason for the genus name is obvious ; Professor Hammer lead the field expeditions under "extremely difficult conditions"). The herbivore was some 25ft long and weighed-in at 4~6 tonnes ; at the time of life, the area was between 55 and 65 degrees south, suggesting a climate similar to the Falkland Islands or Tierra del Fuego.

The popular conception of dinosaurs as slow-moving, cold-blooded animals has long been challenged by such finds of high-latitude dinosaurs. One would expect the mainstream news sites (Slashdot included) to pick up on this publication as further evidence that the dinosaurs were much more diverse than that. After all, the only significant land animals in present-day Antarctica are penguins ; penguins are birds ; birds are dinosaurs (for any meaningful use of "birds", "are" and "dinosaurs") ; so one could make a good case that Antarctica IS the continent which has been dominated by dinosaurs for the last 200 million years. Quoth the penguin : "we don't need no steenkin' furry Mammalia on this here continent!"
However, since Antarctica is probably the most Linux-laden continent on the planet, and Antarctica is also the "dinosaur continent" (as I've just argued), then some FUD-merchant is going to make the false deduction that this means Linux is a dinosaur, instead of the correct deduction that dinosaurs are really well adapted to their extreme environments.

For the editors : Why is this under Topic:Mozilla? Because it's the closest match available in the list of topics — theropod and all that jazz.

NASA's Voyager 2 spacecraft has found that our solar system is not round but is "dented" by the local interstellar magnetic field of deep space, space experts said on Monday. The data was gathered by the craft on its 30-year journey into the edge of the solar system when it crossed into a sweeping region called the termination shock, they said. It showed that the southern hemisphere of the solar system's heliosphere is being pushed in or "dented." Voyager 2 is the second spacecraft to enter this region of the solar system behind Voyager 1, which entered the northern region of the heliosheath in December 2004.

Margaret Rouse writes "As 2007 draws to a close, the Oxford American Dictionary has proclaimed "locavore" the Word of the Year 2007 and tech media will put out endless lists of Words to Watch in 2008. And I wondered, where is the list of new words that will be added to the dictionary in 2008? Merriam-Webster has been strangely quiet, so I invited whatis.com contributors to start a list of their own. Here you go — tech words that should be added the dictionary in 2008."

It's official. Ogg technology has been removed from the HTML5 spec, after Ian caved in the face of pressure from Apple and Nokia. Unless massive pressure is exerted on the HTML5 spec editing process, the Web authoring world will continue to endure our modern proprietary Tower of Babel.

Note that HTML5 in no way required Ogg (as denoted by the word "should" instead of "must" in the earlier draft). Adding this to the fact that there are widely available patent-free implementations of Ogg technology, there is really no excuse for Apple and Nokia to say that they couldn't in good faith implement HTML5 as previously formulated.

Fur-Q writes "Nasa says its robot rover Spirit has made one of its most significant discoveries on the surface of Mars. Scientists believe a patch of ground disturbed by the vehicle shows evidence of a past environment that would have been perfect for microbial life. The deposits were probably produced when hot spring water or steam came into contact with volcanic rocks. On Earth, these are locations that tend to teem with bacteria, said rover chief scientist Steve Squyres. "We're really excited about this," he told a meeting of the American Geophysical Union (AGU)."
