diegocg quotes Kernel Newbies: Linux 4.11 has been released. This release adds support for bigger memory limits in x86 hardware (128PiB of virtual address space, 4PiB of physical address space); support for AMD Secure Memory Encryption; a new unwinder that provides better kernel traces and a smaller kernel size; support for the zstd compression algorithm has been added to Btrfs and Squashfs; support for zero-copy of data from user memory to sockets; support for Heterogeneous Memory Management that will be needed in future GPUs; better cpufreq behaviour in some corner cases; faster TBL flushing by using the PCID instruction; asynchronous non-blocking buffered reads; and many new drivers and other improvements. Phoronix has more on the changes in Linux 4.14 — and notes that its codename is still “Fearless Coyote.” Read more of this story at Slashdot.

Linux 4.14 Has Been Released
An anonymous reader quotes a report from Fast Company: While airport terminal architecture has a solid history of style and innovation, rarely is a proposal put forth to utterly redesign the runway. But that’s precisely the aim of Henk Hesselink, a Dutch scientist working with the Netherlands Aerospace Center. Dubbed the “endless runway, ” Hesselink’s brainchild is a 360-degree landing strip measuring more than two miles in diameter. Since airplanes would be able to approach and take off from any direction around the proposed circle, they wouldn’t have to fight against crosswinds. And three planes would be able to take off or land at the same time. Hesselink’s team uses flight simulators and computerized calculations to test the unconventional design, and have determined that round airports would be more efficient than existing layouts. With a central terminal, the airport would only use about a third of the land of the typical airport with the same airplane capacity. And there’s an added benefit to those living near airports: Flight paths could be more distributed, and thereby making plane noise more tolerable. BBC produced a video detailing Hesselink’s circular runway concept. The concept is fascinating but there are many questions the video does not answer. Phil Derner Jr. from NYC Aviation writes via Business Insider about some of those unanswered questions in his article titled “Why the circular runway concept wouldn’t work.” The fundamental issues discussed in his report include banked runway issues, curved runway issues, navigation issues, and airspace issues. What do you think of Hesselink’s concept? Do you think it is preposterous or shows promise? Read more of this story at Slashdot. 
Apple has disbanded its division that develops wireless routers in a move that further sharpens the company’s focus on consumer products that generate the bulk of its revenue, Bloomberg reports. From the article:Apple began shutting down the wireless router team over the past year, dispersing engineers to other product development groups, including the one handling the Apple TV. Apple hasn’t refreshed its routers since 2013 following years of frequent updates to match new standards from the wireless industry. The decision to disband the team indicates the company isn’t currently pushing forward with new versions of its routers. Routers are access points that connect laptops, iPhones and other devices to the web without a cable. Apple currently sells three wireless routers, the AirPort Express, AirPort Extreme, and AirPort Time capsule. The Time capsule doubles as a backup storage hard drive for Mac computers.

An anonymous Slashdot reader writes: TSA checkpoints caused 6, 800 American Airlines passengers to miss their flights in just one week this spring, and the problem isn’t improving. “Two years ago the Transportation Security Administration (TSA) offered $15, 000 to anybody — literally anybody — who could come up with an idea to speed up airport security…” writes Popular Science. “They wouldn’t say who won or for which idea, but since we’re here two years later with longer wait times than ever, it’s fair to say it hasn’t lived up to the groundbreaking ideals of that call to action… Now in summer 2016, the TSA recommends arriving three hours early instead of a mere two.” So this spring the Seattle-Tacoma airport replaced many of the TSA staff with private screeners, although “Private security operates under strict direction from the TSA, and even those airports that heavily utilize private contractors still have a lot of TSA personnel in the back rooms…” according to the article. “The ability to do exactly what the TSA does, only faster and cheaper, seems to be the major draw.” Now 22 U.S. airports are using private screeners, although the Seattle and San Francisco airports are the only ones with significant traffic. The article also cites a Homeland Security report which discovered that investigators were able to smuggle a test bomb past security checkpoints in 67 out of 70 tests.

Planetary Ventures LLC, a Google shell company, just signed a very expensive lease on a very large building and airfield in Silicon Valley. The lease in question will cost the search giant $1.16 billion over the term of 60 years. The building and airfield in question is the Moffett Field, where Google’s founders have been landing their private jets for years. Read more… 
Flying from LA to San Francisco on business is a task normally fraught with stress and rage. But today, my journey begins from a better place. Instead of the gargantuan mess that is LAX, my Uber rolls up to a tiny airport three miles to the east. I start to realize just how different my work commute will be today. Read more… 
First time accepted submitter chentiangemalc writes While Australia is on “high alert” for terror threats a man walked past a Sydney Airport security screening while engrossed in his iPad and delayed flights for an hour. From the article: “This event was captured on CCTV and unnerved officials so much that they evacuated passengers. As the Sydney Morning Herald reported, the man found himself (or, perhaps, didn’t) going into the terminal through an exit passage that clearly was convenient for him, but less convenient for the hordes of passengers who not only had to be removed from Terminal 3, but also re-screened. A spokeswoman for Qantas told the Morning Herald: ‘The man disembarked a flight and left. It appears he wasn’t paying attention, was looking at his iPad, forgot something and walked back past (the security area).'” Read more of this story at Slashdot.
