Two new Windows 8.1 SKUs coming: Standalone Enterprise and low-cost Bing edition

Microsoft is expected to expand the lineup of Windows 8.1 versions with at least one, and probably two, new editions of the operating system. The first is a straightforward affair. At the moment, Windows Enterprise is only available to organizations buying Software Assurance agreements. Microsoft has confirmed to ZDNet that from March 1, Windows Enterprise will be sold to any company with an Open, Select, or Select Plus plan. This will enable companies that don’t want to pay for Software Assurance’s features such as the automatic upgrade entitlements and extras such as the Microsoft Desktop Optimization Pack to have a way to get their hands on the Enterprise edition. Microsoft is also making changes to the interactions between Software Assurance and Windows Pro; you can read the full, complicated story at Directions on Microsoft , written by perhaps the only people on earth with a solid understanding of how Microsoft’s licensing works.

Black holes cheat on the Eddington limit to export extra energy

The shocked gasses of the micro quasar are structured in the same way as those of this actual quasar. NASA, ESA, S. Baum and C. O’Dea (RIT), R. Perley and W. Cotton (NRAO/AUI/NSF), and the Hubble Heritage Team (STScI/AURA) Black holes got their name because they have such intense gravity that, once inside their event horizons, not even light can escape. Somewhat ironically, they’re also some of the brightest objects in the Universe. That’s entirely because of things that happen outside of the event horizon. There, the hole’s intense gravity draws matter into a disk and raises it to very high energies. The disk emits lots of light on its own and sends out jets of high energy particles that emit even more as they interact with the surrounding interstellar material. But this process has a limit—literally called the Eddington limit. At some point, the radiation emitted by the black hole starts driving off the surrounding matter, effectively cutting off its own food supply. You can view the Eddington limit as the point where matter intake is optimal; below it, the hole can swallow more than the environment’s feeding it, while above, matter is being driven off before it can be eaten. Now, thanks to new observations of a black hole in the Southern Pinwheel galaxy (Messier 83), researchers have found that the Eddington limit isn’t an absolute cap on the amount of energy a black hole can emit out into its surroundings. Their observations suggest that this particular black hole sends out almost as much energy in the form of accelerated particles. Read 7 remaining paragraphs | Comments

The day the Mario Kart died: Nintendo’s kill switch and the future of online consoles

flickr user: Andrew Huff Nintendo fans, mark your calendars for May 20, 2014. As Nintendo announced yesterday , that’s the last day you’ll be able to use the Nintendo Wi-Fi Connection to play hundreds of online games on the Wii and Nintendo DS. Single-player modes for those games will still work, of course, but any parts of the games that require an Internet connection will be completely non-functional in a matter of months. The shutdown will affect some of both systems’ most popular games, some of the best-selling games of all time. Suddenly, over 34 million copies of Mario Kart Wii and 23 million copies of Mario Kart DS will be severely diminished. The tens of millions of people who own the DS Pokemon games will no longer be able to trade their beasts or battle online. Animal Crossing: Wild World and Super Smash Bros. Brawl will be less functional for over 11 million players each. Sure, as a practical matter, relatively few of these tens of millions of players are still making regular use of online servers for games that are sometimes pushing nine years old. If they were, Nintendo would probably have more interest in continuing to maintain those servers on the theory that it would lead to some more very-long-tail sales for its online-enabled games. On the other hand, Nintendo could be more interested in trying to force more players off its “legacy systems” and on to the Wii U and 3DS, which of course still have active online support.

ESA’s Gaia mission set to survey the galaxy with biggest camera in space

An artist’s rendering of what Gaia will look like when deployed in space. ESA After its successful launch in December, the European Space Agency’s (ESA) Gaia has now taken up its position in orbit and is ready to survey the skies. With the help of two onboard telescopes focused onto the largest-ever camera sent to space, the space observatory is expected to catalog nearly one billion stars throughout its 5-year mission. ESA’s Gaia will map stars in the Milky Way. It will do this by measuring the brightest billion objects and determining their three-dimensional distribution and velocities. It also has the ability to measure the temperature, mass, and chemical composition of each of the objects. The brightest objects won’t necessarily need to be very bright in order to be included in the catalog. Gaia will be able to discern objects up to 400,000 times dimmer than those visible to the naked eye. And the positional accuracy of its measurements are akin to measuring the width of a human hair at a distance of 500 km. Read 9 remaining paragraphs | Comments

Exoplanet discovery rate goes from a trickle to a flood

The Kepler spacecraft NASA Today, NASA’s Kepler team has announced that it has developed a new technique to verify the existence of many of the planetary candidates in its back catalog. The technique, which relies on the presence of multiple planets in the system, has led to the single largest announcement of new planets in history: 715 of them, orbiting a total of 305 stars. Most of these are small, between the sizes of Earth and Neptune, and are tightly packed in the inner regions of the systems in which they reside, but four appear to be in the habitable zone. If you visit Kepler’s home page , you’ll see a count of confirmed planets in the upper right (it’s currently at 961). Hover over it, and you’ll see there are over 3,800 unconfirmed planetary candidates. Those candidates come from the method that Kepler uses to discover planets: watching for a mini-eclipse that causes a slight dimming of their host star’s light. A similar pattern can be caused by a dim star orbiting in the system (a configuration called an eclipsing binary system), which raises the prospect of false positives. In the past, this has generally involved multiple follow-up observations with a large telescope, which has held back the announcement of confirmed planets to a relative trickle. However, there have been a number of discoveries that have been based on Kepler data alone. These discoveries have come from multi-planet systems, where the planets gravitationally interacted, speeding up or slowing each other down. This activity creates regular variations in the timing and duration of the eclipses as the exoplanets transit between their host star and Earth. Read 6 remaining paragraphs | Comments

Twitter restores $50,000 @N username to its owner

In January, Naoki Hiroshima lost his Twitter handle, @N, to the hands of a hacker who used social engineering and extortion to wrest the username from Hiroshima’s hands. But today Twitter restored it to him after more than a month of the username being suspended. After @N was stolen, Hiroshima wrote a post explaining how the theft happened. Ars published the story (which originally appeared on Medium ), as well as an account of a man whose more valuable @jb handle was almost hijacked using the same methods. In Hiroshima’s case, a hacker was able to obtain some credit card information from his PayPal account and used that to reset the login credentials on his GoDaddy account. Then, the thief modified several details pertaining to Hiroshima’s domain so that he was unable to access his own site’s information. When the thief couldn’t reset the password for @N, he turned to extortion, contacting Hiroshima and demanding he reset the password to his Twitter account or suffer the destruction of his website’s domains.

World of Warcraft’s $60 level-boosts reflect important economic reality

That’s only 67 cents per level. ORDER NOW! WoW Insider In games, as in life, the only truly nonrenewable resource is time. Thus, anything that saves a player time in getting something they want will have some important real-world value. World of Warcraft seems to finally be acknowledging this basic economic fact of life, letting players pay $60 to instantly level any character all the way up to level 90 in its upcoming expansion. Blizzard announced back at Blizzcon 2013 in November that players who purchased the upcoming Warlords of Draenor expansion would be able to instantly level a single character up to level 90 as a free bonus, thereby gaining the ability to take part in new content that’s balanced for characters from level 90 to the new level cap of 100. Then, in January, the company said it was also “testing out a feature that gives you the option to purchase a character upgrade directly,” allowing players with multiple characters to get the instant boost without, say, buying multiple copies of the expansion (which isn’t yet available for preorder). Last week, WoW Insider noticed a “Level 90 character boost” item briefly listed in the in-game shop during server maintenance before being quickly removed. The asking price on the listing: $60.

Artificial muscles made with fishing line

Fishing line of different diameters, formed into the coiled-coils used in these experiments. Science/AAAS Take a rubber band and twist it. Keep twisting it until it starts to collapse onto itself and form larger loops—it’s something you can do with almost any strand-like structure. Now, scientists from the University of Texas at Dallas in Richardson are taking advantage of this property in everyday materials such as fishing line and sewing thread and using it to make artificial muscles. The scientists took pieces of fiber that were a few hundred micrometers long and twisted them until they began to coil. As the pieces coiled, the twisted fibers became shorter and thicker; once tightly coiled, the scientists heat-treated them to prevent the fibers from unfolding. If heat is applied to the finished coil after this procedure, the individual fibers try to untwist. The untwisting causes the coils to expand in volume as they shorten in length, just like a muscle. The researchers found that if they made the fiber form larger coils in the same direction as the initial twists, the fibers contracted. If the fibers were made to coil in the opposite direction from the twist, the fibers expanded. By combining large quantities of these twisted fibers, the team could produce artificial muscles with above-average characteristics. Read 3 remaining paragraphs | Comments

Next-generation Broadwell NUCs coming late 2014, says leaked roadmap

Ivy Bridge NUC on top, Haswell NUC on the bottom. What will the next one look like? Andrew Cunningham Intel’s “Next Unit of Computing” (NUC) mini desktops are apparently one of the few segments in the PC industry actually seeing some growth, and a new roadmap leaked by FanlessTech shows that Intel is already planning the next versions. According to the roadmap, Intel is planning three new NUC models based on next-generation Broadwell chips, all scheduled to launch toward the end of 2014. FanlessTech [ars_story_side post_id=”397297″][/ars_story_sidebar]Two of the new NUC models are targeted at consumers, and will use next-generation Core i3 and Core i5 CPUs codenamed “Rock Canyon.” Like the current Haswell NUCs, they will include USB 3.0, mini HDMI, and mini DisplayPort outputs. The mini DisplayPort outlets can power either a 4K display or three lower-resolution displays simultaneously. The mSATA slot that current NUCs use for their SSDs will be replaced by an M.2 slot , which can provide faster storage speeds via the PCI Express bus. Wi-Fi, Bluetooth, and an IR sensor will both be built in, as will a bay for a standard 2.5-inch hard drive. The most interesting departure from current NUCs will be swappable lids, which can add either NFC or wireless charging capabilities to the NUCs. The idea of using a desktop as a wireless charging pad isn’t entirely new—we saw a desktop or two that offered this capability at this year’s CES—but a NUC-sized box could serve as a nice wireless charging pad for smartphones and tablets.

Netflix packets being dropped every day because Verizon wants more money

Anthony Fine The battle over who should pay to carry Netflix traffic is heating up again, and one of the main players blames Verizon’s greed for the poor performance that many consumers see when trying to watch streaming video. Cogent Communications CEO Dave Schaeffer made his case in an interview with Ars yesterday, saying Verizon is refusing to upgrade the infrastructure that carries Internet traffic from one network to another unless outrageous demands for payment are met. The network connections between Cogent and Verizon, crucial for carrying streaming video and other content to Verizon’s home Internet customers, “are full,” Schaeffer said. “They are more than full. They are so full that today a significant amount of packets are being dropped between the networks.” Read 39 remaining paragraphs | Comments
