No more lawsuits: ISPs to work with RIAA, cut off P2P users

In a stunning turn of events, the US music industry has ceased its long-time litigation strategy of suing individual P2P file-swappers. Instead, with New York Attorney General Andrew Cuomo acting as a broker, the RIAA has signed voluntary "graduated response" agreements with major Internet service providers. Those currently on the receiving end of an RIAA lawsuit, though, will have to see it through to the (very) bitter end.

The Wall Street Journal (subscription) broke the story, and Ars has confirmed all details given in the piece.

Europe-style graduated responses 

While the agreement itself comes as a surprise after years of lawsuits that have numbered in the tens of thousands, the contours of the deal remain comfortably familiar. Europe is leading the way in hashing out graduated response programs, and the RIAA plan sounds like a mix of the current English and French approaches to the issues.

As in England, the deal is voluntary, has no official government enforcement, and will not have ISPs passing user information on to the RIAA. Instead, the RIAA notifies ISPs about suspected infringement using IP addresses; the ISP then privately looks up its subscriber information and forwards a notice telling the person to stop.

But, as in France, penalties are coming (the voluntary UK scheme is currently "notification only"). They remain undefined at the moment, though the RIAA confirms to Ars that they will include account suspension for users who continue to share files illegally.

The key difference between Europe and the US is the lack of government pressure. New York Attorney General Cuomo did make it clear to the music industry that the lawsuits have been unhelpful and that he hoped to see a different approach, but nothing like the government pressure to cut a deal that we have seen in England or France has been mooted here.

Which leads to the obvious question: what do ISPs get out of the deal? They aren't under any serious pressure to act on this if they don't believe it to be in the interests of their companies or subscribers, but the RIAA makes clear that several leading ISPs are already on board. But they do get a tremendous goodie bag under the Christmas tree: congestion relief.

ISPs have been worried about P2P traffic, especially on access networks (and especially on upstream access networks in cable systems), but the "net neutrality" debate and the Comcast P2P case at the FCC have limited the options that American ISPs can take. The solution many appeared to settle on was nondiscriminatory bandwidth capping; that is, do whatever you want with your connection, use any protocol or application, but you only get a certain amount of monthly capacity.

Suddenly, ISPs gain a tremendous new tool. One study in the UK showed that most people sharing music would stop when made aware that their activity was being tracked and that they were not, in fact, anonymous. Should that hold true in the US, ISPs would presumably see massive decreases in P2P traffic. The customer notifications can be blasted out by e-mail, making the whole process quick and easy for ISPs. As is usual for these sorts of schemes, questions still remain about what sorts of judicial processes will be in place to contest notifications and penalties, and what happens to a household Internet connection when Dad finds his access canceled even though he's never shared a file in his life?

The end of lawsuits

For now, though, the graduated response program will have one immediate effect. The file-sharing lawsuits will largely come to a halt, though the RIAA tells us it reserves the right to go after people who continue to ignore the notifications. That means colleges and universities no longer have to worry about "pre-litigation notices" and a stream of subpoenas seeking student info, dead grandmothers and kids in housing projects won't be hit up for $4,000 settlements, and an unbelievably brutal public relations disaster will basically come to an end.

As for current cases, tough luck; the RIAA intends to see them through. But what about Jammie Thomas, the single mother in Minnesota who found herself the most public face of the RIAA litigation campaign after the first full trial for illicit file-swapping? Thomas' trial is actually over, and the judge has vacated the original decision. The RIAA is seeking to have that original verdict restored, but if that fails, the RIAA will have to prosecute Thomas all over again in order to squeeze any cash out of the handful of songs she was accused of sharing.

Would they do it? An RIAA spokesperson tells us, "If the appeal is granted and an appeals court agrees with the jury in the original trial, she'll continue to be held liable." Reading between the lines, we might expect the case to go away if that original verdict is not reinstated.

A step in a better direction 

News about the entire program will be controversial, but we think it's a big step in a better direction. The lawsuit campaign largely ends. Initial notifications about file-swapping will be purely informative, not punitive. The move does not introduce ISP filtering (notifications are generated by the RIAA), and neither does it pass user information from ISPs back to the music industry. It should eventually remove most of the reasons ISPs have trotted out to defend discriminatory traffic shaping. The Interwebs may get a bit faster. Interesting new music services that the RIAA has recently allowed, like Last.fm and the Amazon DRM-free music store, mean that more legal choices are available as a "carrot" to complement the new "stick."

The real question here is twofold. First, how will file-swappers respond? No doubt plenty will dig in, encrypt everything, switch to obscure protocols, or start using direct download services. A pretty tremendous percentage of casual users, though, will curtail their activity after receiving their first notice, especially once the ISP sanctions are finalized.

Second, how will other industries respond? Music is traded freely on the Internet, but in terms of volume, video content is the real target. The movie business will want in on the arrangement. After that, e-book vendors might demand ISP assistance. And the makers of crochet patterns (which turn out to be traded surprisingly often online without permission).

So long as two conditions are met, though—no ISP has to do any filtering and a workable judicial process is in place to oversee the complaints and handle appeals—even widespread use of the program by many industries might not turn out to be a big deal, either for users or ISPs. Industry would police the 'Net, turn over the information, not get user information in return, and be accountable to some sort of oversight/appeals body. It could be a lot worse.

Plenty of "ifs" are involved in the new project, and there are plenty of unanswered questions. But the deal certainly sounds better than what preceded it, and not just "better" in the sense that it's better not to stab yourself in the hand than to stab yourself. Combined with the music industry's recent moves toward voluntary blanket license models, it's at least possible that the long-running Cold War between music fans and the major labels will undergo some global warming of its own.

Now, who do we talk to about putting out some better music?

No more lawsuits: ISPs to work with RIAA, cut off P2P users

Mars Orbiter Indicates Mars Was Habitable

The latest research indicates Mars was habitable because of a new mineral found on the planet

The Mars Reconnaissance Orbiter has found an important mineral on the Martian surface that leads researchers to believe the planet once was hospitable to life.

The MRO found carbonates, which is formed in alkaline water when water and carbon dioxide mix with calcium, magnesium or iron.  Carbonates can be found on Earth in locations where life survives, which makes it a significant find on the Red Planet.

"It would have been a pretty clement, benign environment for early Martian life," Brown University graduate student Bethany Ehlmann said.  "It preserved a record of a particular type of habitat, a neutral to alkaline water environment."

Because carbonates dissolve quickly in low pH solutions, it could have taken longer than expected to find carbonates on the Red Planet.  MRO's findings are about the size of a football field and deposits are limited.

Ehlmann and fellow researchers made the presentation during the American Geophysical Union's Fall Meeting 2008 in San Francisco, with research being published in Science.

Researchers believe the carbonate is 3.6 billion years old, and it was found at the edge of a 930-mile-wide basis located in a mid-latitude region of the planet called Nili Fossae.  Oddly enough, Nili Fossae will not be one of the locations researched by the Mars Science Laboratory NASA rover in 2011.

Primitive life would have liked living in the regions with carbonates.

Researchers have collected even more data on the possible existence of water on the Red Planet:  gullies created by flowing water, minerals that can only be created with water, and several ancient lakes on the surface.  Scientists continue to research how and what kind of living things could have lived on Mars.

Habitable Planets: Four Types Proposed

The origin of life and the habitability of worlds other than Earth are two of the biggest mysteries facing science today. Much research has been dedicated to these topics, but there is still a lack of definite answers.

Jan Hendrik Bredehöft from the UK's Open University has been considering habitability on other worlds. "I'm one of those guys who takes a piece of meteorite, grinds it up and finds out what the organic chemistry is in there," said Bredehöft.

Based on these types of studies, he has come to believe that habitable worlds can be split into four categories, each with varying likelihoods of being home to extraterrestrial organisms. This has great potential for assisting the search for life in the universe, particularly as technology is now progressing to the stage where

direct imaging of extrasolar planets is possible. Bredehöft presented his ideas at Europlanet's latest Planetary Science Congress.

His four groups of habitable worlds are: Earth-like, Mars-Like, Europa-like and water-worlds.

Taking each of these in turn, he considered their potential for hosting complex life. Earth-like words are the first class, and a kind of "control" since we already know such worlds are capable of sustaining complex life. Earth-like worlds feature an appropriate atmosphere, liquid water, moderate temperature ranges, and stable climates.

The second class of planets are those that were once much like Earth, such as Mars and Venus. "For some reason these planets left the classical habitable zone," said Bredehöft. "Mars became too dry, there's very little water left, at least not liquid water. Venus became just so enormously hot due to the greenhouse effect."

Still, Bredehöft believes there is some chance for life to exist on this type of world. He reasons that organisms could have developed when the planet was more hospitable, and this life could maintain a grip even through the hard times. "Once life has established itself it is really hard to kill off," said Bredehöft. "There have been absolutely devastating events in Earth's history that might have wiped out all kinds of life, but usually these served to further enhance biodiversity, rather than destroy it."

A chilly existence

Bodies that possess liquid water, but under an ice layer rather than on the surface, make up the third class of worlds.

Jupiter's moon Europa is a classic example from our own cosmic neighbourhood. Could there be life in places like this? Bredehöft's ideas here are particularly pertinent as often these worlds do not fit neatly into the conventional view of habitable zones. Europa, for example, lies beyond the solar system's temperature zone where water can remain as a liquid on a planet's surface.

However, there is still potential for life.

The traditional view of habitable zones thinks of a local star as being the prime energy source. But on icy worlds like Europa, other factors come into play, such as the gravitational pull of another planet. Worlds with liquid water hidden beneath icy layers could potentially be inhabited by simple organisms despite being far from the conventional habitable zone, so long as energy is provided in some other way.

Water-worlds

The fourth kind of habitable planets are made almost entirely of water. These hypothetical worlds would be Mercury to Earth-sized and would feature extensive oceans.  Unlike oceans on Earth, the water on these types of planets would not be in contact with silicates or other rocks.

"These planets can either be completely made of water with high pressure ice at the core, or they can have bodies of liquid water that are separated from a silicate core by a thick layer of high pressure ice," said Bredehöft.

One theory for life's origin on Earth says organic material collected in shallow pools and then became concentrated by clinging to the surface of rocks. Eventually, this early life spread into the wider ocean. Another theory for life's origin is that the necessary chemistry occurred at hydrothermal volcanic vents.  On water worlds, however, these scenarios are impossible.  Therefore, Bredehöft thinks life is not likely to originate on such planets.

"The amount of water on such a planet would be so huge, you would need unbelievable amounts of carbon components concentrated together for a chance of life. It's far too diluted," said Bredehöft.

Considered opinions

After considering all the facts, Bredehöft said the best bet to find extraterrestrial ecosystems is to hunt for Earth-like planets, after all. However, he doesn't think Earth-like worlds will necessarily have advanced life.

"We don't know whether the level of complexity or the size of organisms living on Earth is essentially a logical outcome of evolution or whether it is just some fluke experienced here," said Bredehöft. "Is having talking intelligent beings on the surface of the planet the pinnacle of evolution? We just assume so because we like to see ourselves as something special."

With the rapid pace of development in planet-hunting technology, it is only a matter of time until we learn much more about exotic extrasolar planets and moons, and are able to glean vital information about their properties. Until then though, scientists like Bredehöft will continue to theorise about discoveries.

So in Bredehöft's carefully considered opinion, what kind of organisms are we most likely to find? "Probably something slimy," he said.

Practical tech: getting better holiday pictures

Imagine you open one of your gifts on Christmas, and you are elated to discover you've received a brand new digital camera. Or perhaps you already have a decent digital camera, and you bring it along to the family get-together. Either way, you invariably end up being "the person in charge of holiday pictures." Ars would like to give you some quick tips to get the best pictures with the least amount of hassle.

Though most modern DSLRs and point-and-shoot cameras have an impressive, if often overwhelming, array of settings and features, usually you can be safe using just a handful of settings that apply to your particular tastes in photography and ignore the rest. And, in many cases, the best solution is often a low-tech one.

When it comes to settings on your camera, usually some small adjustments to your flash settings can have a dramatic effect on your image. Photography is all about light, and the quality of light from the tiny built-in flash units in compacts and DSLRs is usually not very flattering. Try turning the flash off, and strive to use as much available light as possible. You can take pictures near a window for dramatic lighting, or turn on extra lights if you're indoors.


Typical flash settings, from left to right: auto flash, red-eye reduction,
force flash (always on), flash off, and "night portrait" or "night flash sync."

You can also use the "night flash sync" setting if your camera offers it (most current models do). This mode blends a flash exposure with a longer exposure to blend flash and natural light. The trick with both options is that you will typically have slower than usual shutter speeds, which can result in some blur. Taking advantage of the high-ISO settings of most newer digital cameras can help a lot here. Practicing holding steady and letting your subjects know to hold still can also help.

Most digital cameras offer special "scene modes," which will tweak the settings of the camera for certain picture taking situations but still give completely automatic operation. Using the "portrait mode" will give a much better rendition for shots of your family members and friends.

If you have a DSLR and an accessory flash unit that has a titling flash head, you can use a slightly more advanced technique called "bounce flash." Simply tilt the flash head up toward the ceiling at a 45–60° angle (the closer you are, the more steep the angle) and fire away. The flash will bounce off the ceiling, creating a large, soft light source. The indirect light is much more flattering than a flash that fires directly from the camera, and your camera's TTL flash system will take care of controlling the exposure.


Here the flash is bounced off the ceiling for softer light;
also note the tight composition.
Canon EOS Rebel, Tamron 28–75/2.8 zoom, Canon 420EX flash.

But the way to get the most improvement is a decidedly low-tech method: controlling your composition. All the technology in the world won't give you a better "photographic eye." A few simple tips, though, can give you much better results with minimal fuss.

The first advice I always give when people ask, "How can I take better pictures?" is to get closer. Zoom lenses can help, and by all means use them, but in most family settings there is no reason you can't just get closer. Even when you think you're close, try getting even closer. The single biggest mistake I often see in snapshots is that the subject only fills about 20 percent of the frame. Try and fill as much of the frame as possible with your subject. You'll be surprised how much more you'll like the pictures you take that way.


See how the faces fill most of the frame? This shot is outdoors, but mixes flash with ambient light, and background details are out of focus. The details don't distract but do provide context. Canon EOS 20D, Canon 17–40/4, Canon 580EX flash.

The second tip I can give is to move your subjects away from walls. Many people like their subjects up against a wall to use the wall as a neutral backdrop. It's not a bad idea, but putting your subjects right against a wall can create distracting shadows, and anything on the wall, like pictures, shelves, lights, even thermostats, will simply distract the eye from your subject. Moving the subject even a few feet away from the wall will usually cause such details to be out of focus, and thus less distracting. Combine with the first tip of getting closer to your subject, and the effect will be even better.


Here the natural light coming in a large window is used for lighting. Background details are there, but the subjects are far enough away that they don't distract. Canon PowerShot SD300, ISO 400, flash off.

The last tip I can suggest it to pay attention to the background. Try to eliminate any distracting elements or bright lights. Since it's the holidays, try to include elements that will easily place the subject in context, like a Christmas tree or other decorations. Like the previous hint, though, try to keep enough distance that background elements don't distract from the subject.

One of the nice things about digital photography is that it doesn't really cost anything to make mistakes. Don't be afraid to experiment a little, and try to take two or three shots of each subject. You can keep an eye on the LCD screen to see if your exposure is decent and if your composition is good. If not, go for another shot. Not every picture you take will be gallery quality, but you can delete the bad shots later, and no one will be the wiser.

Commercial Spaceport in New Mexico Gets FAA Launch License

New Mexico's Spaceport America has reached a key milestone on its road to become the future home for Virgin Galactic's suborbital space tourism spaceliner fleet and other launch firms.

The New Mexico Spaceport Authority (NMSA) announced Monday that it received a license for

vertical and horizontal launches from the Federal Aviation Administration's Associate Administrator for Commercial Space Transportation (FAA/AST).

The FAA/AST issued the license after providing a vital Environmental Impact Study Record of Decision required for construction to begin on the sprawling spaceport.

New Mexico's Spaceport America is billed as the nation's first "purpose-built" commercial spaceport. The site is 30 miles (48 km) east of Truth or Consequences and 45 miles (72.4 km) north of Las Cruces.

Political hoops

There have been a number of political hoops to move Spaceport America closer to reality.

For example, the New Mexico State Legislature set certain requirements for spaceport funding, which included the formation of a local tax district, the issuance of an FAA Environmental Impact Statement record of decision and launch site license, and a signed lease agreement with an anchor tenant.

Roadwork to the spaceport is already underway, and the architectural firm of URS/Foster + Partners is completing their final design for Spaceport America's terminal and hangar facility.

Spaceport America is expected to cost a total of some $225 million to construct.

According to NMSA Executive Director Steven Landeene, all is now on track to start spaceport construction in the first quarter of 2009. Furthermore, the NMSA is expected to have a signed lease agreement with Virgin Galactic later this month.

"A few issues remain that are being worked. We anticipate lease signing prior to the end of the year," he told SPACE.com.

Virgin Galactic is offering seats at the going rate of $200,000 per person onboard the now-in-development WhiteKnightTwo/SpaceShipTwo suborbital launch system. Those vehicles are taking shape at Scaled Composites in Mojave, Calif.

Along with Virgin Galactic, Spaceport America has been working with a host of aerospace firms such as Lockheed Martin, Rocket Racing Inc., Armadillo Aerospace, UP Aerospace, Microgravity Enterprises and Payload Specialties.

The New Mexico Spaceport Authority currently projects vertical launch activity to increase in 2009 and construction to also begin in 2009 with the terminal and hangar facility for horizontal launches completed by late 2010.

Child's Play surpasses $1 million goal

In what is altruism at its most sublime, Child's Play organizers announced that the charity has raised nearly 36,000 rupees in 2008, which at the current exchange rate equals more than a million dollars – all to help sick children in need of both fun and games.

While not discounting the impact of tedious school bus excursions, the milestone owes much thanks to the recent Child's Play Charity Dinner Auction in Seattle, which took in an impressive $200,000 over the course of the evening. It warms our hearts when gamers can put down their guns and spread a little cheer for a good cause. Bravo.

First-Ever Photo of Liquid on Extraterrestrial World

Wiredtitan2_2 The Huygens probe has captured an image of what may be the first drop of liquid ever observed on an extraterrestrial surface.

The photo is evidence that liquids may exist on the surface of other planets and moons, not just frozen lakes. And liquid is more likely habitat for extraterrestrial life.

Among the pictures snapped by the Huygens probe after landing on Saturn's moon Titan in 2005, one appears to show a dewdrop made of methane that briefly formed on the edge of the probe itself (indicated by arrow at bottom of image on right). Scientists think heat from the probe caused humid air to rise and condense on the cold edge of the craft.

Though Huygens may have helped produce it, the methane drop is still the first liquid directly detected at a surface anywhere beyond Earth.

Like Earth, Titan has clouds, lakes and river channels, and it may be the only other place in the solar system where liquid evaporates from the surface and returns as rain. "Aside from Earth, it's the most exciting world there is," said lead author Erich Karkoschka of the University of Arizona in Tucson.

The Cassini space probe, which took data from above the moon after separating from the Huygens lander, detected what scientists believe are lakes of liquid methane on Titan's surface. Microbes that eat methane thrive on Earth, and scientists think pools of methane could be comfortable homes for similar organisms on Titan.

Because Titan's current atmosphere is a lot like the early Earth's, the lakes could be a lab for studying the origins and early evolution of life.

Astronomers have speculated since they found methane in the atmosphere in 1983 about whether the moon's methane rain falls in violent thunderstorms, light drizzles or some other form. So far, no one has caught it on camera.

The hundreds of images snapped by Huygens, from the time it hit the atmosphere until its power ran out an hour after it landed, revealed only faint, wispy clouds that looked nothing like rain clouds, Karkoschka said.

None of the images showed evidence that it had rained during the previous few years, according to an analysis to be published in the journal Icarus. And some images suggested that Titan’s lower atmosphere was full of small dust particles, which would have been cleared out by rain.

But the scientists noticed light splotches in some of the pictures that hadn't been there moments before. Some of them had spots that initially looked like raindrops because of their uniform size and smooth edges, but analysis showed they were most likely electronic imprints created by cosmic rays.

However, Karkoschka said, "One of those spots was so big that it really cannot be a cosmic ray." He concluded that it was a real, short-lived dewdrop, so close to the camera that it must have condensed on a cold metal shield designed to protect the camera lens from direct sunlight.

Robert West, a planetary scientist at the Jet Propulsion Lab in Pasadena, California, thinks the dewdrop is "a cute observation," but he's more interested in the lack of rainfall. "There are reports in the literature that concluded there is a drizzle going on near the surface," he said. "The fact that Huygens didn’t find anything is significant."

Scientists Discover Cloak of Plasma Around Earth

Exactly how many hit points the cloak of plasma adds is unknown

There is much that we don’t know about our own planet and our atmosphere. Scientists strive to learn more as a way to not only understand our own planet, but to be able to apply this understanding to planets outside our solar system in a search for life.

Scientists have discovered something new in the Earth's atmosphere described as a warm cloak of plasma. The feature is part of the Earth's magnetosphere that is key to protecting the planet from solar wind and radiation. The only visible parts of the Earth's magnetosphere are the aurora borealis and the aurora australis. While most people don’t think much about the magnetosphere, it can have an effect on our lives.

Professor of Physics Rick Chappell from Vanderbilt University told Space.com, "Although it is invisible, the magnetosphere has an impact on our everyday lives. For example, solar storms agitate the magnetosphere in ways that can induce power surges in the electrical grid that trigger black outs, interfere with radio transmissions and mess up GPS signals. Charged particles in the magnetosphere can also damage the electronics in satellites and affect the temperature and motion of the upper atmosphere."

The new region was discovered after Chappell and other researchers pieced together what they call a "natural cycle of energization" that accelerates low-energy ions in the Earth's atmosphere into the higher energy levels found in regions of the magnetosphere.

The warm plasma cloak starts on the night side of the planet and wraps around the dayside according to the researchers. As the cloak reaches the afternoon side of the planet, it gradually fades away. Due to that fact the cloak only surrounds about 3/4 of the planet.

The cloak is fed by the low-energy particles lifted into space over the Earth's poles, carried behind the Earth on its magnetic tail, and then turned 180 degrees by a kink in the magnetic field. The particles are then boosted back towards the Earth into the region called the plasma sheet.

A key part of the analysis that led to the discovery was a program developed by Dominique Delcourt, a researcher from France. Delcourt developed a program that predicted where particles in the atmosphere go. One of the predictions made by the software was how ions moved and ultimately ended up in the warm plasma cloak.

Chappell told Space.com, "These motions are very complicated. Ions spiral around in the magnetic field. They bounce and drift. A lot of things can happen, but Dominic developed a mathematical code that can predict where they go."

He continued, "We have recognized all the other regions for a long time, but the plasma cloak was a fuzzy thing in the background which we didn't have enough information about to make it stand out. When we got enough pieces, there it (warm plasma cloak) was!"

Chappell and his colleges used observations of satellites to measure the properties of ions in different locations of the magnetosphere. When these observations were applied to the computer code designed by Delcourt the discovery of the warm plasma cloak was made.

The Yawn Explained: It Cools Your Brain

If your head is overheated, there's a good chance you'll yawn soon, according to a new study that found the primary purpose of yawning is to control brain temperature.

The finding solves several mysteries about yawning, such as why it's most commonly done just before and after sleeping, why certain diseases lead to excessive yawning, and why breathing through the nose and cooling off the forehead often stop yawning.

The key yawn instigator appears to be brain temperature.

"Brains are like computers," Andrew Gallup, a researcher in the Department of Biology at Binghamton University who led the study, told Discovery News. "They operate most efficiently when cool, and physical adaptations have evolved to allow maximum cooling of the brain."

He and colleagues Michael Miller and Anne Clark analyzed yawning in parakeets as representative vertebrates because the birds have relatively large brains, live wild in Australia, which is subject to frequent temperature swings, and, most importantly, do not engage in contagious yawning, as humans and some other animals do.

Contagious yawning is thought to be an evolved mechanism for keeping groups alert so they "remain vigilant against danger," Gallup said.

For the bird study, the scientists exposed parakeets to three different conditions: increasing temperature, high temperature and a control temperature. While yawning did not increase during the latter two conditions, it more than doubled when the researchers increased the bird's ambient temperature.

A paper on the findings has been accepted for publication in the journal Animal Behavior.

"Based on the brain cooling hypothesis, we suggest that there should be a thermal window in which yawning should occur," Gallup said. "For instance, yawning should not occur when ambient temperatures exceed body temperature, as taking a deep inhalation of warm air would be counterproductive. In addition, yawning when it is extremely cold may be maladaptive, as this may send unusually cold air to the brain, which may produce a thermal shock."

The parakeets yawned as predicted.

It's now believed yawning operates like a radiator for birds and mammals.

If air in the atmosphere is cooler than brain and body temperatures, taking it in quickly cools facial blood that, in turn, cools the brain and may even alter blood flow. Prior studies reveal yawning leads to a heightened state of arousal, so a morning yawn may function somewhat like a cup of coffee in providing a jolt of energy.

The new findings also explain why tired individuals often yawn, since both exhaustion and sleep deprivation have been shown to increase deep brain temperatures, again prompting a yawn-driven cool down. Yawning additionally appears to facilitate transitional states of the brain, such as going from sleep to waking periods.

Gordon Gallup, Jr., a State University of New York at Albany psychologist, did not work on the study, but, as Andrew Gallup's father, paid close attention to the research. The senior Gallup also happens to be a leading expert on the science of yawning and other widespread evolved traits.

"It is interesting to note that instances of excessive yawning in humans may be indicative of brain cooling problems," Gallup, Jr., told Discovery News, pointing out that patients with multiple sclerosis often experience bouts of excessive yawning "and MS involves thermoregulatory dysfunction."

He added, "Bouts of excessive yawning often precede the onset of seizures in epileptic patients, and predict the onset of headaches in people who suffer from migraines."

In the future, researchers may focus more on brain temperature and its role in diseases and their symptoms. But the new study on yawning changes the popular notion that yawns are mere signs of boredom.

On the contrary, as Gallup said, "yawning more accurately reflects a mechanism that maintains attention, and therefore should be looked at as a compliment!"

Team Fortress 2 Update: Significant Patch Released, Next Class Update Confirmed

Valve released a rather sizable Team Fortress 2 update today, adding new features to some of the shooter's existing abilities.

The developer also recently confirmed that the next class update will indeed be applied to the Scout, though that particular patch is not expected before the new year.

As for the patch changes, the engineer is now able to upgrade his teleporters and dispensers to a third level, providing faster recharge and dispensing rates, respectively.

 

Spies have gained the ability to recharge their cloak by picking up ammo, and the demoman's sticky bombs can now be entirely destroyed by all types of bullets.

The full list of tweaks is copied below:

  • The Engineer's teleporters can now be upgraded to level three. It will recharge faster the higher level it is
  • The Engineer's dispensers can now be upgraded to level three. It will give out metal and heal faster as it is upgraded
  • Spies will be able to recharge their cloaking ability by picking up ammo off of the ground or from health cabinets
  • Some changes to the second part of the first stage of Goldrush to give the attackers more of an advantage
  • Any weapons that fire bullets (shotguns, sniper's machine gun, heavy's minigun, etc.) can now break apart the Demoman's stickybombs
  • The icon on the HUD for a person calling for Medic will now give more information to the medic (if the target is low on health, on fire, etc.)
  • Added an achievement tracker that will allow people to choose specific achievements that they are trying to get
  • There is now a custom icon for death messages when the player was killed from a critical hit
  • Added a new particle effect for when a player enters the water
  • Added smoke to the feet of a rocket jumping soldier
  • Players will now have some particles swirling around them so other players can see when they are overhealed

Google Chrome hits 1.0

Google Chrome 1.0

Just in case you needed any proof that software version numbers are meaningless, Google has updated Google Chrome, it's web browser to version 1.0 (or 1.0.154.36 to be exact). Yesterday the latest version of the software was version 0.4.154.29.

So why remove the beta label now, especially when the 4 year old Gmail service is still officially in beta? Well, the official explanation is because the company's goals for stability and performance have been met. But it also likely has something to do with Google's plans to convince hardware makers to preload the web browser on computers -- something they may be reluctant to do with beta software.

So aside from the version number, what else is different in the latest build? Honestly, I'm not sure. Most of the items that Google showcases in its blog post about the new release are updates that we've already seen like the addition of a bookmark manager, and improved speed and performance.

More updates are still in the works. Google is promising support for plugins, RSS feeds, and form autofill features.

Ciel II satellite successfully reaches orbit, gears up for DISH service

If there were any doubts about the purpose of the Ciel II satellite, it's safe to say those questions have been answered. According to a glowing release on International Launch Services' website, the latest bird to leave its hands has successfully reached space, and now it waits to "ultimately be moved to 129 degrees West longitude where it will deliver digital television services to Canada and the contiguous United States." Brian Neill, chairman of the Ciel Satellite Group, was quoted as saying that "now that the spacecraft has delivered an initial signal, Ciel, our founders, investors, and our customer, DISH Network, can look forward to Ciel II's operation early next year." No word on what exactly DISH will use this for "early next year," but it doesn't sound like we'll be waiting long to find out.

Hulu adds buffer meter, full screen option for embedded videos

Hulu buffer meter

Online video site Hulu has rolled out two new features, including one I've been hoping for since the site first launched. You can now watch embedded videos in full screen. Next time you see a Hulu video embedded in a web page, just scroll over the video until you see a full screen icon in the upper right hand corner.

The other new features is an on-sreen meter that shows you the video buffering progress. Unlike some web video sites, Hulu will not buffer an entire video for legal reasons. In other words, Hulu doesn't want you figuring out a way to permanently save a video that's been temporarily downloaded to your hard drive. But in order to make video playback smooth, Hulu will buffer up to 5 minutes of video at a time. Now when you pause a Hulu video you'll see an indicator letting you know the buffer status.

HP flexible display uses 90% less materials, will be cheap to make

hp_flexibledisplay.jpg

The era of handheld flexible displays just got a little closer when HP rolled out this prototype it developed with the Flexible Display Center at Arizona State University. Said to be unbreakable, the plastic scrolling screens use HP's self-aligned imprint lithography (SAIL) technology, a low-cost process that's a whole lot like printing on a sheet of plastic.

What does this mean for us? The screen's simplified manufacturing processes will result in cheap but super-sharp and colorful flexible displays for a new generation of laptops, cell phones, and eventually, electronic newspapers like we saw in Minority Report. While this tech is in its infancy now, analysts say the market for such screens will grow to $2.8 billion by 2013.

Office Depot to Cut Over 100 Retail Stores, 2,200 Employees

Taking care of business...

The casualties in the slowing economy continue are continuing to mount. When most people think of office supply stores, companies like Staples and Office Depot -- and to a lesser extent, Office Max -- spring to mind. Today, Office Depot announced that it is cutting stores and trimming its headcount.

The majority of the store closures will come directly from U.S. operations; however, a few Canadian stores will be affected. A total of 112 underperforming stores will be shuttered bringing Office Depot’s total count to 1,163 stores.

In addition to the 112 retail store closures, 33 of company's distribution centers will also be shutdown.

The loss of the retail stores and distribution centers means that 2,200 Office Depot employees will be out of a job within the next three months -- the company will also take a charge of between $270 million to $300 million USD.

"It's not enough to really close the gap and make a meaningful impact compared to Staples and the mass merchant competitors," said R.J. Hottovy, an analyst for Morningstar. "But it's probably a Band-Aid on a flesh wound."

"We expect (Office Depot) shares to benefit from this announcement, though it does not significantly counteract the tough reality of low underlining profitability, and obviously does not remedy cyclical challenges," said Goldman Sachs analyst Matthew Fassler.

Office Depot has plans to close an additional 14 stores next year and the company reduced its plans for new stores from 40 to 20 during 2009.

Spore 2008's Most Pirated Game, Says TorrentFreak

Sporescreen

In an unofficial race for the dubious honor of most pirated game, Electronic Arts' Spore has toppled the competition, amassing a rather impressive 1.7 million illicit downloads since its September rele.

The list, compiled by BitTorrent news site TorrentFreak, is comprised of data acquired from "a representative sample of BitTorrent sites." While it isn't necessarily a scientific survey, it does provide a relatively accurate view of what software pirates were up to this year.

Is Spore's success on the piracy charts related to its

unpopular DRM? TorrentFreak seems to think so. The game was reportedly downloaded 500,000 times within the first ten days of release, a trend that apparently never died down.

In 8th place with a meager 645,000 downloads is Fallout 3, joining Far Cry 2 and Pro Evolution Soccer 2009 as the only other games from 2008 that even made the list. No intrusive DRM, less piracy? Maybe so.

Sweet Find in Search for Alien Life

A sugar molecule that's linked to the origin of life has been detected in a region of our galaxy where habitable planets could exist. The sweet find is good news in the search for alien life, the researchers say.

Called glycolaldehyde, the sugar molecule is considered a life ingredient because it can react with a substance called propenal to form ribose, a central constituent of ribonucleic acid (RNA), which is similar to DNA and considered one of the central molecules in the

origin of life.

An international team of scientists used the IRAM radio telescope in France to detect glycolaldehyde in a massive star-forming region of space, some 26,000 light-years from Earth. (One light-year is the distance light will travel in a year, or about 6 trillion miles, or 10 trillion km.)

They looked for the emission of certain wavelengths within the radio part of the electromagnetic spectrum. Molecules each emit a distinctive band of radio wavelengths, which can be used as a fingerprint for the molecules. 

"This is an important discovery as it is the first time glycolaldehyde, a basic sugar, has been detected towards a star-forming region where planets that could potentially harbor life may exist," said researcher Serena Viti of the University College London.

Previously, the organic sugar had been detected toward the center of our galaxy, where conditions are extreme and not conducive to planet-forming compared with the rest of the galaxy.

The new discovery, which will be detailed in a forthcoming issue of Astrophysical Journal Letters, was in an area distant from the galactic center. In addition, the sugar was found in a swirl of gas and dust around a collection of stars. "Possibly, this material is actually rotating around the stars, which may imply that it's a disk and that's where planets may form," Viti told SPACE.com.

She added, "Also the fact that it's just a normal star-forming region suggests that the production of this molecule could be common throughout the galaxy."

The detection of one life ingredient also improves the chances that the molecule exists alongside other molecules essential to life and in regions where Earth-like planets may exist, she said.

"The fact that a basic sugar so directly linked to RNA is common makes you think the basic ingredients for life are out there," Viti said. "They're not just on Earth."

2008 Will Be Just a Second Longer

On Dec. 31 this year, your day will be just a second longer.

Like the more well-known time adjustment, the leap year, a "leap second" is tacked on to clocks every so often to keep them correct.

Earth's trip around the sun — our year with all its seasons — is about 365.2422 days long, which we round to 365 to keep things simpler. But every four years, we add 0.2422 x 4 days (that's about one day) at the end of the month of February (extending it from 28 to 29 days) to fix the calendar.

Likewise, a "leap second" is added on to our clocks every so often to keep them in synch with the somewhat unpredictable nature of our planet's rotation, the roughly 24-hour whirl that brings the sun into the sky each morning.

Historically, time was based on the mean rotation of the Earth relative to celestial bodies and the second was defined from this frame of reference. But the invention of atomic clocks brought about a definition of a second that is independent of the Earth's rotation and based on a regular signal emitted by electrons changing energy state within an atom.

In 1970, an international agreement established two timescales: one based on the rotation of the Earth and one based on atomic time.

The problem is that the Earth is very gradually slowing down, continually throwing the two timescales out of synch, so every so often, a "leap second" has to be tacked on to the atomic clock.

The International Earth Rotation and Reference Systems Service is the organization that monitors the difference in the two timescales and calls for leap seconds to be inserted or removed when necessary.  Since 1972, leap seconds have been added at intervals varying from six months to seven years — the most recent was inserted on Dec. 31, 2005.

In the United States, the U.S. Naval Observatory and the National Institute of Standards and Technology keep time for the country. The Naval Observatory keeps the Department of Defense's Master Clock, an atomic clock located in Washington, D.C.

The new extra second will be added on the last day of this year at 23 hours, 59 minutes and 59 seconds Coordinated Universal Time — 6:59:59 pm Eastern Standard Time.

Mechanisms such as the Internet-based Network Time Protocol and the satellite-based Global Positioning System (GPS) depend on the accurate time kept by atomic clocks.

Fill Your Car with Starbucks Diesel?

Coffee is well known for being able to power the economic engine that is America's workforce. But its not particularly good at powering actual engines. It's much better at making compost, if you're going to try and find something to do with it.

Well, that may no longer be the case. Some chemical engineers at the University of Nevada are reporting that they've made a high quality bio-diesel from coffee grounds. Coffee grounds are actually about 15% oil, which isn't a great percentage for a bio-diesel crop. Unless you don't have to grow it, and companies might actually pay you to help get rid of it.

The researchers estimate that their process could produce about 340 million gallons of bio-diesel from coffee world wide, and that they could make about $8 M in profits just from Starbuck's grounds.

It's not going to save the world, but it's certainly a smart use for what is otherwise just trash.

Surf the world's radio stations with Radio Beta

Radio Beta

There are dozens of web sites that aggregate radio streams from around the globe. But Radio Beta is one of the few that I've found that lets you surf by geographic location and not just genre.

Want to find that old station you used to listen to when you went to college in Chicago, but can't remember its call letters? Just click the "Radios from United States" link and browse until you find it. Always wondered what drive time radio sounds like in Australia? You can search by country too.

Radio streams are also sorted by genre, allowing you to peruse a huge list of rock, pop, 60s, 70s, or 80s music. Or if you know the station you're looking for you can just use the search box.

Radio Beta has its own audio player built in, which allows you to listen to music while searching the site. The player only works with Firefox and Internet Explorer for now.

Mars Science Laboratory Delayed to 2011

The Mars Science Laboratory mission, a jumbo rover originally slated to launch for the red planet next year, has been delayed until 2011, NASA announced today.

"We will not be ready to launch by the hoped-for date next year," said NASA Administrator Michael Griffin at a briefing.

A major

review of the mission conducted earlier this year had concluded that MSL "had a solid chance of making the 2009 launch" if the launch window was extended into October 2009, which was done, and an additional $200 million was added to the project, said Ed Weiler, associate administrator for NASA's Science Mission Directorate at NASA Headquarters in Washington, D.C.

But new technical issues that came up since that review as well as missed delivery schedules have prompted NASA officials to further delay the mission to avoid a "mad dash to launch," Weiler said. "Failure on this mission is not an option, the science is too important," he added.

The MSL rover has a complex suite of instruments that can test the Martian surface for signs of past potential habitability, including onboard chemistry labs and a laser that can zap rocks to determine their composition.

The rover may also leave some of its originally-planned equipment behind.

The rover is much larger than its Mars Exploration Rover (MER) cousins, Spirit and Opportunity, weighing in at about 2,040 pounds (925 kg) and currently still operating on Mars. MSL will also use a completely novel way of getting down to its landing site called Sky Crane, which will have cords that attach it to the lander. As the rover falls to the surface, the Sky Crane's thrusters should slow the rover's descent as the crane uses the cords to lower the lander.

The mission now is delayed for two years because launch windows to Mars are few and far between because of the relative positions of Mars and Earth.

"We're really only a few months behind schedule, not two years behind schedule," said Doug McCuistion, director of the Mars Exploration Program at NASA Headquarters.

Landing sites for the mission, which were recently whittled down to a final four, will likely be unaffected by the delay, McCuistion said.

The delay will add an estimated $400 million to the mission, which could impact other NASA programs, McCuistion said. NASA will aim to delay programs instead of cutting any, officials said at a briefing today.

The particular technical issues delaying the mission are with the rover's actuators, which McCuistion describes as a combination of a motor and a gear box. The actuators control anything in the rover that moves, including the wheels and robotic arms.

"They're absolutely crucial to the success of this mission," McCuistion said. Without them "we'd basically have a metric ton of junk on the surface" of Mars, he added.

Most of the rover's hardware has been completed and the two years until launch will be spent dealing with the actuators and any other technical issues that crop up.

"It's not like it's going in a big plastic bag and sitting in the corner for two years," McCuistion said.

Griffin said: "I have full confidence in the JPL [Jet Propulsion Laboratory] team to work through the difficulties."

This Computer Knows Where You Should Live

Holy crap if this isn't amazing! I just discovered a website that knows exactly where you should live.

Simply stick in the addresses of all of the places that you and members of your family regularly go (grocery stores, work place, daycare, dog walking, strip club, whatever) and this awesome little machine will weight them appropriately and then tell you where exactly, within your town, you can live using the least amount of gas.

Now, it might not find you a place in the nicest neighborhood, or with the most appropriate median home values, but it will decrease your commute time. And, frankly, driving can be the worst part of many people's lives. I know, because I once had a gigantically evil commute, and was a worse person because of it.

This, combined with my favorite home-locating site, Walkscore, could definitely provide home-buyers with some much needed tools to determine whether that cheap 4-bedroom in the new suburb is really a better deal than the pricier 3-bedroom in town.

The application calculated that I should live on the railroad in the middle of an abandoned lumber mill. Which, actually, is surprisingly apt. The abandoned lumber mill is one of the most central locations in town, and developers are currently working to convert it into a densely built, green community.

Well done computer! I think I may move there...once there are houses.

Valve says DRM is stupid, but Microsoft still doesn't get it

Valve is a wonderfully open company—in many cases, direct questions sent to the publisher will be answered by a member of the creative team within hours. One gamer recently e-mailed Valve and asked why he saw EA's logo on a commercial for Left 4 Dead: he bought the game via Steam but didn't want to support EA after the Spore DRM debacle. He got a reply from a managing director at the company, Gabe Newell, that was to the point: EA only handles distribution for the physical product, and Valve thinks most DRM is "just dumb."

"Left 4 Dead is developed entirely by Valve. Steam revenue for our games is not shared with third parties. Around the world we have a number of distribution partners to handle retail distribution of our games (i.e. make discs and boxes). EA is one of those partners," Newell wrote. In other words, if you buy Left 4 Dead through Steam, EA doesn't see any of your money. This should be good news for gamers who want to slaughter some zombies but don't want to break their EA boycott

Newell doesn't have kind words for the use of digital rights managements. "As far as DRM goes, most DRM strategies are just dumb. The goal should be to create greater value for customers through service value (make it easy for me to play my games whenever and wherever I want to), not by decreasing the value of a product (maybe I'll be able to play my game and maybe I won't)," he wrote. "We really really discourage other developers and publishers from using the broken DRM offerings, and in general there is a groundswell to abandon those approaches."


Buying Left 4 Dead on Steam supports Valve, not EA

It's easy for him to say; Steam is its own form of DRM, one that makes programs like SecuROM redundant. "You'd have to ask Valve for specific numbers," PC Gaming Alliance President Randy Stude told Ars, "but I believe piracy on Steam is very low." You can add games you obtained at retail to the Steam service to take advantage of its social networking features, but you need your CD key to do it; cracked games are out of luck. Don't assume that buying a game via Steam means escaping SecuROM however, as EA has included the program on some its own games that it has released via Steam, such as Crysis: Warhead.

If we don't kick you in the gut, can we punch you in the face? 

Newell's take attracted the attention of others in the gaming industry. "I think the problem with DRM is not so much the particular method used, but the attitude behind it. It makes us feel like we're all being punished for the sins of the few," Microsoft's Games for Windows Community Manager Ryan Miller wrote on his blog. "It is also pretty clear that most DRM is not a problem for the pirates, just for the legitimate consumers. These two factors combine to make a ton of bad feelings on the consumer side."

This is an arguable sentiment: gamers do care about the method of DRM that is used. Programs such as SecuROM (which don't uninstall along with the game) and limits on the number of installations allowed anger PC gamers. When we reported on the use of SecuROM in Grand Theft Auto IV on the PC, many of our readers pledged not to buy the game on principle. 

Miller addresses that controversy directly. "Rockstar has put an interesting twist on the much-maligned software by removing the install limits that have plagued other games, though the software still installs components that can be very difficult to remove should you want them off your hard drive," he wrote.  "It seems like a reasonable compromise to me, but what do you think? Is the lack of install limits enough to overlook the installation of code you can't remove?"

This is the sort of question that may sound reasonable from Miller's point of view, but will enrage PC gamers. SecuROM serves no purpose other than to annoy legitimate customers, and a version of the game that lacks the program (and is superior for that) will be available to pirates as soon as the game is released, if not before. The fact that Rockstar won't limit installations, a new twist on DRM that has drawn bile from gamers and seemingly given pirates the high ground, doesn't excuse the use of SecuROM in the game. 

While Steam is a step in the right direction, giving gamers the ability to play games on multiple systems without having to worry about losing discs or CD keys, some gamers have reported issues getting their games to work in offline mode, and worry about Valve shutting down the servers at some point in the future. Piracy is a complex issue with no easy answer, but what's clear is that gamers are less and less willing to put up with intrusive DRM technology in their games, but there doesn't seem to be much of a movement to lessen its use among game publishers.

What the industry has to understand is that gamers have the upper hand, as they can simply go to the torrents for a free version of each game that includes no DRM. Until publishers do more to welcome their legitimate customers as friends instead of treating them as potential pirates, piracy will continue to eat at profits and morale.

Huge Sun Shield Built for Space Telescope

The largest sun shield ever made has been created for the Hubble Space Telescope's successor. The enormous sun blocker will unfold in space into the size of a tennis court, despite being hundreds of thousands of miles away from the help of a human hand. 

The

kite-shaped layers of the sun shield for NASA's James Webb Space Telescope (JWST) will block out the sun's ultraviolet radiation and protect the machinery from high-speed impacts of tiny space debris.

No other space observatory has had such an enormous or membrane-based sun shield, said Mark Clampin, NASA's Webb Telescope Observatory project scientist at Goddard Space Flight Center in Greenbelt, Md. The Hubble Space Telescope is equipped with a light shield, but it is nothing like the new sun shield in the works for the Webb. In addition, other solar shields, such as the one aboard the infrared Spitzer Space Telescope, are fixed and so don't need to be deployed once in orbit, as the Webb will be.

"If you could imagine, this would be like going outdoors applying sunscreen of 'SPF' of 1.2 million on your skin," said Martin Mohan, program manager for the telescope at Northrop Grumman in California. "Previous to this crucial technology, materials with thermal properties that reflect the sun without being heated did not exist."

The James Webb Space Telescope, set for launch in 2013, will make observations mainly in the infrared range of the electromagnetic spectrum, with some capability in visible light. In space, JWST will reside in an orbit that's 1 million miles (1.5 million km) from Earth at what is called the second Lagrange point.

Giant sun blocker

Once it is erected, the sun shield will sit below and perpendicular to the telescope's upright, primary mirror, which will span 21.3 feet (6.5 meters) in diameter. (For comparison, Hubble's primary mirror measures about eight feet, or 2.4 meters, in diameter.) The sun shield consists of five layers of Kapton (a mylar-like material made by DuPont) with aluminum and special silicon coatings to reflect the sun's heat back into space.

While the sun-facing side of the sun shield will block out sunlight, the other side facing away from the sun will minimize light scattering as well as heat.

"The other side of the telescope you think of as being dark," Clampin said. "But when you're trying to find the first galaxies in the universe, even a small amount of light that's scattering from different places on the telescope can really hurt you."

Clampin added, "And we're talking about infrared light here, so heat sources on that side of the telescope can actually scatter light into the telescope and be seen as a signal, so you have to be very careful."

Overall, the sun shield will keep the telescope at a cryogenic minus 387 degrees Fahrenheit (minus 233 degrees Celsius). Any warmer than that and the heat given off from the telescope would corrupt the infrared observations.

"Infrared is heat radiation. In order to see the faint glow of infrared heat from distant stars and galaxies, the telescope has to be very cold," said Jonathan Gardner, NASA's deputy senior project scientist for the Webb Telescope at Goddard. "If the telescope were heated by sunlight or the warm glow of the Earth, the infrared light emitted by the telescope would outshine its targets, and it wouldn't be able to see anything."

New technologies

The sun shield technology is new in many more ways, its developers said.

For instance, complete passive cooling, in which refrigerants aren't used to keep temperatures down, is new to the field of telescopes and should keep JWST alive for its mission lifetime of no less than five and a half years, with an optimistic goal of 10 years, Clampin said. The other infrared observatories relied on cryogens, such as liquid nitrogen or liquid helium as their primary means of cooling, Clampin said.

"The advantage of that is it gives you a pretty long lifetime for the telescope," Clampin told SPACE.com, referring to the no-refrigerant approach for JWST. "The other approach is to put a telescope in a big fridge and fill it with coolant but that coolant slowly boils off and you have a limited life."

(For comparison, Spitzer relies partially on liquid helium to keep its instruments chilled.)

Due to its size, the sun shield will have to be compactly folded, much like a parachute, around the telescope in order to fit into its launch rocket.

"There have been a lot of missions that have unfolded large antenna," Clampin said. "To our knowledge it's one of the first missions where we are unfolding a really big membrane."

And so the engineers had to figure out how to fold the coated membranes, which make up the layers of the sun shield, to make sure they didn't get tangled upon opening and so that the unfolding didn't rub off any of the coatings, Clampin said.

Once the shield and the rest of the telescope are on their way to final orbit, engineers at Northrop Grumman will issue commands to the Webb Telescope to unfold the sun shield.

Auditorium: The Prettiest Musical Puzzle Game You'll Play Today

Sometimes we like our Hot Flashes to soothe us, rather than stir us into a reflexes-required panic. In fact, after playing Auditorium, the musical puzzle... experience, I've poured myself a strong cup of adult-style eggnog.

You too may want to wash away the day with hard liquor and be delighted by what Auditorium has to offer. Its creators describe the Flash game as a "process of discovery and play." It's one of those titles where outlining how it plays spoils some of the fun — figure it out on your own.

The Auditorium site teases that the developers may be convinced to port it to the iPhone or consoles, given the right encouragement and, of course, proper amount of funds via donation. We'll see.

Microsoft Xbox 360 Kicks PS3 Butt on Black Friday

Microsoft says Xbox 360 outsold PS3 3 to 1

The console wars are still raging even though all three of the top-tier consoles are getting older now. Microsoft, Sony, and Nintendo are battling for the gamers dollars and Microsoft has claimed a victory over Sony for the all-important Black Friday shopping dollars.

Microsoft announced that the Xbox 360 had record-breaking sales over the Black Friday/Thanksgiving weekend. Microsoft giddily notes that the Xbox 360 outsold the PS3 by a margin of 3 to 1 and turned in a 25% increase from Xbox 360 Black Friday sales in 2007.

Microsoft says that it also saw record-breaking sales for its software with Xbox games like Gears of War 2, Fable II, and Lips turning in the highest game attach rate of any console at 8.1 games per console.

Microsoft Senior VP of Interactive Business Don Mattrick said in a statement, "We entered into the Black Friday sales period with cautious optimism, knowing that dollar for dollar, Xbox 360 offers more social entertainment value than any other console on the market. Record Black Friday sales in the U.S., coupled with our existing global install base of 25 million and an online community of more than 14 million Xbox LIVE members, have laid the groundwork for continued global sales momentum in 2009."

Microsoft claims that the Xbox 360 has outsold the PS3 week over week across Europe since the September price drop bringing the basic Xbox 360 system to $199.99 worldwide. The Jasper revision of the Xbox 360 was recently launched with revisions to make the console cooler among other things.

First look: can Songbird 1.0 replace iTunes, WMP?

Last month, we curled up with a pair of headphones and a 1.0 release candidate of Songbird, an open-source media player based on Mozilla technology. As a cross-platform music player built with Mozilla's trademark extensibility in mind, Songbird soared with its integration of services like concert ticket notifiers, lyric downloading, and artist bios. Today the official Songbird 1.0 is shipping, and it even supports DRM-protected iTunes Store files, so we took another look at the feature roadmap and how the final version shaped up.

For a recap, Songbird is available for Windows XP/Vista, Linux, and Intel-based Mac OS X PCs. The app takes an iTunes-meets-Firefox approach, as it is based on Mozilla's XML User Interface Language (XUL) and Gecko rendering engine that powers Firefox, but presents one's music library and add-ons with a UI inspired very much by iTunes. The integration of a tabbed web browser, official add-on support, open architecture, and a focus on playing well with the rest of the music-loving web, however, are what really help Songbird to soar above the competition.

Songbird ships with six add-ons that a brief setup wizard helps users to get started with: iPod Device Support, QuickTime Playback, SHOUTcast Radio, Concerts, Last.fm, mashTape. This means that, out of the box, Songbird can synchronize with Apple's iPod (including the latest generation released in September) as well as a multitude of other devices and cell phones. Sorry, iPhone, iPod touch, and Zune owners: support for your devices is still on the way.

Other notable add-ons include Concerts, which uses Songkick to check for when library artists are giving concerns in major cities across a handful of countries. The Last.fm add-on allows users to "scrobble" a list of songs to the Last.fm community for music discovery and socializing, and mashTape collects artist bios, photos, and videos from around the web.

In addition to having over 70 add-ons available for launch, one of Songbird's greatest strengths is its customizable UI for displaying the content that all these add-ons aggregate. Collapsible panels on the top, bottom, and right side of Songbird's window can display add-ons that bring lyrics, a Cover-Flow-style or unique Photo browser for album art, mashTape content, and anything else you can find in the add-on directory. A handful of alternative themes can also bring more style to Songbird, or even make it feel more at home on your OS of choice.

After taking Songbird's official 1.0 version on a magic carpet ride, it really feels like a solid release that fixed all of the release candidate bugs we ran into. Songbird imported our entire iTunes library perfectly, complete with DRM store files and metadata like song ratings and play counts, and stayed in step whenever we made changes in iTunes. Scanning our library of 9,370 tracks from nearly 1,000 artists for concert tickets in the Chicago area was a snap, and playing songs from our 4G iPod nano or syncing new playlists to it both went without a hitch.


Songbird's Concerts add-on makes it easy to spend as much money as possible seeing artists live

A number of other features are still on their way, however, including some of Songbird's most promising potential as a true media hub. Besides the aforementioned pending device support, Songbird cannot yet watch folders for new media, automatically integrate media from any of the major MP3 outlets like Amazon's MP3 Downloads store and Rhapsody, or rip CDs. On that last point, though, the project says that one-quarter of Songbird's users have already left the realm of physical media behind long ago. and about three-quarters of Songbird's other users are willing to rely on other apps for ripping CDs and grabbing new music.

Features for importing metadata and album artwork from web services are still in the works, and Songbird 1.0 is definitely a music player, as video playback and organization is on the project's lengthy roadmap. Other more minor features, such as the ability to accept commands from keyboards with media keys, are also not present.

Is Songbird 1.0 a viable music player replacement for iTunes, Windows Media Player, and other incumbents? As long as you don't need to manage videos and aren't nuts for the play/pause key on your keyboard, we can answer "definitely." After a two-year journey, Songbird 1.0 is a serious music player competitor, firmly grounded in the vast potential of an open-source community and a focus on incorporating the web into the music experience.
