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.

Rod Logic Computers and Why We Don’t Already Have Them

szczys writes: Carbon Nanotubes and Graphene breakthroughs pop up in the news often enough for them to be considered buzzwords. Most of the time it’s the superconducting properties of graphene that are touted, but molecule-scale structures also hold the promise of building mechanical computing devices that are unimaginably small. The reason we don’t have these things yet comes down to the manufacturing process. Building machines out of carbon molecules is commonly called Rod Logic — a topic many know from the seminal novel The Diamond Age. Al Williams discusses how Rod Logic works and highlights some of the places we’re already seeing these materials like to help cool LED light bulbs, and to strengthen composites.

Maybe You Don’t Need 8 Hours of Sleep After All

schwit1 writes: You’ve heard of the Paleo diet, but the next big thing in health may well be the Paleo sleep schedule. A UCLA researcher studied three hunter-gatherer and hunter-farmer groups — the Hadza in Tanzania, San in Namibia, and Tsimane in Bolivia, “who live roughly the same lifestyle humans did in the Paleolithic, ” as NPR reports — and determined our ancient ancestors may not have slept nearly as much we thought, and may have actually slept less than modern Westerners. “People like to complain that modern life is ruining sleep, but they’re just saying: Kids today!” Jerome Siegel tells the Atlantic . “It’s a perennial complaint but you need data to know if it’s true.” Siegel found that members of the three aforementioned groups sleep between 5.7 hours and 7.1 hours per night. That’s less than is recommended for our health, yet the groups seemed very healthy indeed. (And if you’re feeling insomniac, some earlier Slashdot stories about sleep are also pretty thought-provoking.) Read more of this story at Slashdot.

Moscow State University Releases 10th HEVC Video Codec Comparison

An anonymous reader writes: The Graphics and Media Lab Video Group of Moscow State University has released its tenth video codecs comparison. This latest comparison focuses on HEVC codecs and includes some non-HEVC codecs such as x264 and VP9. The report concludes that Intel’s MSS HEVC Software codec leads the pack in the “fast transcoding” use case whereas x265 takes the lead in the “ripping” use case. VP9 compares favorably to the HEVC codecs in the fixed quality and the speed versus quality test cases. See the PDF version of the report for more details. Read more of this story at Slashdot.

China’s Flash Consumption Grows To 30%; 8TB SSDs Are Coming

Lucas123 writes: Seven of the world’s top 10 smartphone vendors hail from China as does PC giant Lenovo, which is driving up the amount of NAND flash and DRAM the country consumes. This year alone, China is expected to purchase nearly 30% of the world’s NAND flash and 21% of its DRAM, according to a report from TrendForce. Additionally, state-backed companies are trying to break into Western markets with SSDs. For example, Sage Microelectronics (SageMicro), a four-year-old company based in Hangzhou, China, plans to release an 8TB SSD next month that will be based on eMMC flash, and it said it will release a 10TB drive next year.

Terahertz Radiation To Enable Portable Particle Accelerators

Zothecula writes with this Gizmag story about an interdisciplinary team of researchers who have built the first prototype of a miniature particle accelerator that uses terahertz radiation. “Researchers at MIT in the US and DESY (Deutsches Elektronen-Synchrotron) in Germany have developed a technology that could shrink particle accelerators by a factor of 100 or more. The basic building block of the accelerator uses high-frequency electromagnetic waves and is just 1.5 cm (0.6 in) long and 1 mm (0.04 in) thick, with this drastic size reduction potentially benefitting the fields of medicine, materials science and particle physics, among others.” Read more of this story at Slashdot.

Clinton Home Servers Had Ports Open

Jim Efaw writes: Hillary Clinton’s home servers had more than just the e-mail ports open directly to the Internet. The Associated Press discovered, by using scanning results from 2012 “widely available online”, that the clintonemail.com server also had the RDP port open; another machine on her network had the VNC port open, and another one had a web server open even though it didn’t appear to be configured for a real site. Clinton previously said that her server featured “numerous safeguards, ” but hasn’t explained what that means. Apparently, requiring a VPN wasn’t one of them. Read more of this story at Slashdot.

"E-mailable" House Snaps Together Without Nails

MikeChino writes: Your next house could snap together like a jigsaw puzzle without the use of any power tools. Clemson University students designed and built Indigo Pine, a carbon-neutral house that exists largely as a set of digital files that can be e-mailed to a wood shop anywhere in the world, CNC cut, and then assembled on-site in a matter of days. “Indigo Pine has global application, ” says the Clemson team. “Because the house exists largely as a set of digital files, the plans can be sent anywhere in the world, constructed using local materials, adapted to the site, and influenced by local culture.” Read more of this story at Slashdot.

Open-Source Doom 3 Advances With EAX Audio, 64-bit ARM/x86 Support

An anonymous reader writes: Dhewm3, one of the leading implementations of the Doom 3 engine built off the open-source id Tech 4 engine, has released a new version of the GPL-licensed engine that takes Doom 3 far beyond where it was left off by id Software. The newest code has full SDL support, OpenAL + OpenAL EFX for audio, 64-bit x86/ARM support, better support for widescreen resolutions, and CMake build system support on Linux/Windows/OSX/FreeBSD. This new open-source code can be downloaded from Dhewm3 on GitHub but continues to depend upon the retail Doom 3 game assets. Read more of this story at Slashdot.

On-Chip Liquid Cooling Permits Smaller Devices With No Heatsinks Or Fans

An anonymous reader writes: DARPA-funded research into on-chip liquid cooling has resulted in a field-programmable gate array (FPGA) liquid-cooled device that can operate at 24 degrees Celsius, versus 60 degrees Celsius for an equivalent air-cooled device. The cooling fluid resides only nanometers from the heat it must address, and operates so efficiently as to offer potential to stack CPUs and GPUs using copper columns, as well as dispensing with heat-sinks and fan systems. With those components removed, the system can facilitate far more compact designs than are currently feasible. Read more of this story at Slashdot.
