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”.

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.

Functioning Hoverboard Unveiled

An anonymous reader writes: Last year, a company called Arx Pax set up a Kickstarter campaign to develop a functioning hoverboard. Now, the company has demonstrated an updated version of the device, which is fully capable of hovering over a surface made out of conductive metal (video on YouTube). CEO Greg Henderson said, “The hover engine creates a primary magnetic field which is then put over a candidate surface like aluminum or copper. The hover engine then creates swirls of electricity and those create a secondary magnetic field, which propels the firsts.” The device is expensive; Arx Pax is delivering a handful of units to Kickstarter backers who contributed $10, 000. It’s out of the reach of typical consumers, but it does seem to work. Plus, the company is sharing their magnetic field technology with teams taking part in the competition to build pods for a prototype of Elon Musk’s Hyperloop vacuum tube transportation system.

Engineers Create the Blackest Material Yet

schwit1 writes: Researchers have created the least reflective material ever made, using as inspiration the scales on the all-white cyphochilus beetle. The result was an extremely tiny nanoparticle rod resting on an equally tiny nanoparticle sphere (30 nm diameter) which was able to absorb approximately 98 to 99 percent of the light in the spectrum between 400 and 1, 400nm, which meant it was able to absorb approximately 26 percent more light than any other known material — and it does so from all angles and polarizations.

Apple Faces Class Action Lawsuit Over iOS Wi-Fi Assist

An anonymous reader writes: A class-action suit has been filed against Apple in U.S. District Court over Wi-Fi Assist being turned on by default in iOS 9. Wi-Fi Assist is designed to switch to cellular data when a user is trying to perform an action over the internet on a poor Wi-Fi signal. This has the natural side effect of using cellular data. Since iOS 9 turned it on for many users, they weren’t necessarily expecting that extra use, causing some of them to exceed their data caps. A former Apple employee who was in a leadership position for Mac OS X Wi-Fi software has commented on the issue, saying that the Wi-Fi Assist mess was unavoidable given how Apple’s management treats that part of the business. Quoting :”[O]ne particular directorial edict which I pushed back against at the end of my tenure sticks out as not just particularly telling, but deeply misguided: ‘Make it self-healing.’ Self healing in this context meaning that the networking system, Wi-Fi in particular, should try to correct problems that caused the network to fail, which, if you have spent any time trying to diagnose networking issues is a clear misunderstanding of the issues involved. … Asking the devices which connect to this vast complex network of networks to detect, and then transparently fix problems in the infrastructure without the permission of the administrators is, well, it’s absolutely the pinnacle of buzzword driven product management. Real pointy-haired boss territory.” Read more of this story at Slashdot.

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.
