NASA Eagleworks Has Tested an Upgraded EM Drive

An anonymous reader writes: A team of researchers at NASA’s Eagleworks Laboratories recently completed yet another round of testing on Engineer Roger Shawyer’s controversial EM Drive. While no peer reviewed paper has been published yet, engineer Paul March posted to the NASA Spaceflight forum to explain the group’s findings. From the article: “In essence, by utilizing an improved experimental procedure, the team managed to mitigate some of the errors from prior tests — yet still found signals of unexplained thrust.” Read more of this story at Slashdot.

How a Group of Rural Washington Neighbors Created Their Own Internet Service

An anonymous reader writes with a story that might warm the hearts of anyone just outside the service area of a decent internet provider: Faced with a local ISP that couldn’t provide modern broadband, Orcas Island residents designed their own network and built it themselves. The nonprofit Doe Bay Internet Users Association (DBIUA), founded by [friends Chris Brems and Chris Sutton], and a few friends, now provide Internet service to a portion of the island. It’s a wireless network with radios installed on trees and houses in the Doe Bay portion of Orcas Island. Those radios get signals from radios on top of a water tower, which in turn receive a signal from a microwave tower across the water in Mount Vernon, Washington. Read more of this story at Slashdot.

Xen Patches 7-Year-Old Bug That Shattered Hypervisor Security

williamyf writes: ArsTechinca, The Register, and other outlets are reporting that today the XEN project patched a vulnerability in the ParaVirtualized VMs that allowed a guest to access the control OS of the hypervisor. Qubes researchers wrote: “On the other hand, it is really shocking that such a bug has been lurking in the core of the hypervisor for so many years. In our opinion the Xen project should rethink their coding guidelines and try to come up with practices and perhaps additional mechanisms that would not let similar flaws to plague the hypervisor ever again”.

Copyright exemption lets you modify old games to keep them running

You no longer have to dread the day that a game developer shuts off its servers and renders your favorite title unplayable. As part of a series of DMCA copyright exemptions, the US Library of Congress has granted long-sought permission to disable authentication server requirements in games where a server’s shutdown will completely break the experience. Historians can even hack the consoles themselves, if necessary. This doesn’t allow you to tweak games where you’d only lose multiplayer modes, but it does mean that at least some aspects of a classic game will live on.

Immersion Cooling Drives Server Power Densities To Insane New Heights

1sockchuck writes: By immersing IT equipment in liquid coolant, a new data center is reaching extreme power densities of 250 kW per enclosure. At 40 megawatts, the data center is also taking immersion cooling to an entirely new scale, building on a much smaller proof-of-concept from a Hong Kong skyscraper. The facility is being built by Bitcoin specialist BitFury and reflects how the harsh economics of industrial mining have prompted cryptocurrency firms to focus on data center design to cut costs and boost power. But this type of radical energy efficiency may soon be key to America’s effort to build an exascale computer and the increasingly extreme data-crunching requirements for cloud and analytics.

Xbox One gets Xbox 360 backwards compatibility with November 12 update

The new Xbox One dashboard, as originally shown off in June. The new Xbox One dashboard, which will usher in a bunch of new features including Xbox 360 backwards compatibility, will be released on November 12. Confirmation came via a tweet by Larry “Major Nelson” Hryb very early this morning. Microsoft first showed off the “New Xbox One Experience” (that’s its official name) back at E3 in June. The dashboard interface has been completely overhauled: now, instead of looking like the Windows 8 Start screen, it looks a bit more like a Windows 10 app. The interface is very flat, with a heavy focus on typography. Perhaps most importantly, settings, games, social updates, and all of the good stuff is much more easily accessible with a gamepad. The primary focus of the new dashboard, you’ll be happy to hear, is to make it faster and easier to do things. Read 5 remaining paragraphs | Comments

Mimic, the Evil Script That Will Drive Programmers To Insanity

JustAnotherOldGuy writes: Mimic implements a devilishly sick idea floated on Twitter by Peter Ritchie: “Replace a semicolon (;) with a Greek question mark (;) in your friend’s C# code and watch them pull their hair out over the syntax error.” There are quite a few characters in the Unicode character set that look, to some extent or another, like others – homoglyphs. Mimic substitutes common ASCII characters for obscure homoglyphs. Caution: using this script may get you fired and/or beaten to a pulp. Read more of this story at Slashdot.

Ubuntu 15.10 ‘Wily Werewolf’ Released

LichtSpektren writes: Ubuntu 15.10 “Wily Werewolf” is now released and available, along with its alternative desktop flavors (MATE, Xfce, LXDE, GNOME, KDE, Kylin). This release features Linux 4.2, GCC 5, Python 3.5, and LibreOffice 5. The default version is still using X.org display server and Unity7; Mark Shuttleworth has said that Mir and Unity8 won’t arrive until Ubuntu 16.04 “Xenial Xerus.” Not much has changed beyond package updates, other than replacing the invisible overlay scrollbars in Nautilus with the GNOME 3 scrollbars. Phoronix brings us the only bit of drama regarding this release: Jonathan Riddell, long time overseer of Kubuntu, has resigned with claims that Canonical has “defrauded donors and broke the copyright licenses.” Another reader adds a link to a Q & A session with Riddell.

Descent Underground recaptures that Descent multiplayer magic [Updated]

Video: the Descent Underground Early Access gameplay trailer. AUSTIN, TX—About a month ago, we called the retro-themed Descent -style shooter Sublevel Zero an awesome Descent -like experience but lamented its lack of multiplayer. Well, good news this morning for folks who are still craving multiplayer tunnel-shooting: as of 11:00 EDT, Descent Underground is available on Steam Early Access for $29.99. Players will be able to jump in and fly three classes of ships in five maps and a few different game modes. The product of a small Austin company called Descendent Studios founded by former Star Citizen Austin studio head Eric “Wingman” Peterson, Descent Underground was originally envisioned as a Descent clone under the working title “Ships That Fight Underground” (abbreviated as “STFU” ). However, the game changed course when an encounter with an Interplay shareholder led to a licensing agreement with Interplay, the studio that controls the bulk of the Descent intellectual property. The licensing deal meant that the game could be re-envisioned as an actual branded Descent game—though because the licensing agreement doesn’t include the character models or sound assets from the original trilogy, some creativity had to be applied. The result is Descent Underground, a prequel to the original Descent series. In it, the player takes on the role of a miner who remote-pilots drones through mines, blasting other drones and occasionally doing some actual mining to collect resources. Lead designer Peterson explained to us that the eventual goal is to have a metagame that has some hints of Dune about it: players will fly around in a large mothership, cruising through asteroid fields and looking for choice places to mine. A nice asteroid might already have another player group’s ship docked on it, and you can fly up next to it and deploy your own drones to try to fight them for the asteroid. (This is what’s going on in the launch trailer at the top of the page.) Read 20 remaining paragraphs | Comments

950 Pro review: Samsung’s first PCIe M.2 NVMe SSD is an absolute monster

(credit: Orestis Bastounis) The 950 Pro isn’t Samsung’s first consumer M.2 SSD, or even the company’s first PCIe M.2 drive. It is, however, Samsung’s first consumer M.2 and NVMe drive that uses the full performance of four PCIe 3.0 lanes. It is also an upgrade from its predecessor the SM951, in that it uses 3D V-NAND rather than planar NAND. Somewhat disappointingly, the 950 Pro comes in only two capacities for now: 256GB or 512GB, with a 1TB model promised for next year. Samsung is resolute in only producing single-sided M.2 devices to keep the drive’s thickness to a minimum, so the 1TB drive will have to wait until 48-layer 3rd-generation V-NAND is available. Thankfully, no 128GB model will be sold, indicating that 128GB SSDs may be on their way out. UK pricing is pegged at £150 for the 256GB model and £270 for 512GB; in the US, it’s $200 and $350, respectively. As always, expect some variation between retailers with these prices, and in these early days, prices may be slightly higher than what Samsung is quoting. We’re told that the 950 Pro will hit retailers today; we’ll update this story with some links when they first appear. Read 44 remaining paragraphs | Comments
