itwbennett writes: Google's plan to encrypt user data on Android devices by default will get a new push with Android 6.0, also known as Marshmallow. Devices with enough memory and decent cryptographic performance will need to have full-disk encryption enabled in order to be declared compatible with the latest version of the mobile OS. From the ITWorld article: "The move is likely to draw criticism from law enforcement officials in the U.S. who have argued over the past year that the increasing use of encryption on devices and online communications affects their ability to investigate crimes. In addition to encryption, Google also mandates verified boot for devices with AES performance over 50MB/s. This is a feature that verifies the integrity and authenticity of the software loaded at different stages during the device boot sequence and protects against boot-level attacks that could undermine the encryption."

grimmjeeper writes: According to Ars Technica the Windows 10 upgrade option is being selected by default for some users. A dialogue box is appearing that only permits them to reschedule the upgrade process, not cancel it. "For the first year of its availability, Windows 10 is available for free to most Windows 7 and 8 users, and Microsoft has been trying to coax those users to make the switch by delivering the operating system through Windows Update. Until now, the OS has been delivered as an optional update; while Windows Update gives it prominent positioning, it shouldn't be installed automatically. This system has already generated some complaints, as Windows Update will download the sizeable operating system installer even if you don't intend to upgrade any time soon, but, over the last couple of days, the situation seems to have become a little more aggressive. We've received a number of reports that people's systems are not merely downloading the installer but actually starting it up." Update: 10/16 11:35 GMT by S : Microsoft said, "In the recent Windows update, this option was checked as default; this was a mistake and we are removing the check."

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. Update: 10/16 15:11 GMT by T : Note this interesting highlight from the second story linked above: SageMicron is selling not just drives that emphasize capacity over speed, but also a feature that will do doubt appeal to government agencies or private citizens intent on replicating Mission Impossible-style data wiping. The company's "Smart Destruction" function "can be set to erase encryption keys, perform a drive erase or physically fry the memory chips with a pulse of high voltage ... [and] can be triggered using a digital timer, a mobile phone instruction, or by simply pressing a button. 'Yes, it actually smokes sometimes when you push the button,' [Sage U.S. sales director Troy Rutt] said. 'People like that.'"

An anonymous reader writes with the news that Tesla owners today found their cars had been upgraded with the company's new autopilot feature: "That means the next time you see a Model S cruising next to you on the interstate, look closely: It may be driving itself." Adds the submitter: Well, I guess some of you will be celebrating this; but this submitters' fear, is that if this technology becomes pervasive, the skill of operating a vehicle will be lost, as is any skill that isn't practiced regularly. It is unlikely that 'self-driving cars' will reach a point where they can handle 100% of all driving circumstances without human intervention, emergency circumstances being the first and foremost example of what an automated system could not adequately handle unaided; what will we do then, when injuries that could have been avoided or when lives are lost because people aren't competent to operate a vehicle any longer?

An anonymous reader writes: Intel has begun releasing more "Skylake" processors that are cheaper than the launch SKUs of the i5-6600K and i7-6700K. One of the new processors that is now widely available is the Core i5 6500 and it costs just $199 USD — that puts it just a few dollars more than the AMD FX-8370 and significantly less than the higher-end Skylake and Haswell CPUs. At least with Ubuntu Linux, the Core i5 6500 is showing competitive performance that for some workloads puts it faster than Core i7 Haswell/Broadwell processors and much faster than any AMD processors. The Intel Skylake CPUs are fully supported under Linux but the caveat is needing the very latest kernel otherwise there's no graphics acceleration or sound support.

An anonymous reader writes: CloudFlare's content delivery network relies on their ability to shuffle data around. As they've scaled up, they've run into some interesting technical limits on how fast they can manage this. Last month they explained how the unmodified Linux kernel can only handle about 1 million packets per second, when easily-available NICs can manage 10 times that. So, they did what you're supposed to do when you encounter a problem with open source software: they developed a patch for the Netmap project to increase throughput. "Usually, when a network card goes into the Netmap mode, all the RX queues get disconnected from the kernel and are available to the Netmap applications. We don't want that. We want to keep most of the RX queues back in the kernel mode, and enable Netmap mode only on selected RX queues. We call this functionality: 'single RX queue mode.'" With their changes, Netmap was able to receive about 5.8 million packets per second. Their patch is currently awaiting review.

Mickeycaskill writes: Jim Zemlin, executive director of the Linux Foundation, has outlined the organization's plans to improve open source security. He says failing to do so could threaten a "golden age" which has created billion dollar companies and seen Microsoft, Apple, and others embrace open technologies. Not long ago, the organization launched the Core Infrastructure Initiative (CII), a body backed by 20 major IT firms, and is investing millions of dollars in grants, tools, and other support for open source projects that have been underfunded. This was never move obvious than following the discovery of the Heartbleed Open SSL bug last year. "Almost the entirety of the internet is entirely reliant on open source software," Zemlin said. "We've reached a golden age of open source. Virtually every technology and product and service is created using open source. Heartbleed literally broke the security of the Internet. Over a long period of time, whether we knew it or not, we became dependent on open source for the security and Integrity of the internet."

Its improvements include added support for many new ARM boards including the Raspberry Pi 2, major improvements to its multiprocessor-compatible firewall NPF, kernel scripting in Lua, kernel mode-setting for Intel and Radeon graphics chips, and a daemon called blacklistd(8) which integrates with numerous network daemons and shields them from flood attempts.

itwbennett writes: Peter Smith writes that he 'had more or less written off the Nook when Barnes & Noble farmed hardware duties out to Samsung.' But now that Amazon is aiming for the low end with its downgraded Fire tablet line, Barnes & Noble has an opportunity to 'carve out a niche on the higher end of things,' says Smith. And so it has been quietly moving in that direction. Yesterday, Venture Beat wrote about the newly (and stealthily) launched $250 Samsung Galaxy Tab E Nook. As Smith notes, 'the specs for this new tablet aren't anything special,' which might explain the stealthy launch, except that another, pricier Nook tablet apparently came out a month ago (again, according to VentureBeat), the Samsung Galaxy Tab S2 Nook.

An anonymous reader writes: Google has officially taken the wraps off its AMP project — Accelerated Mobile Pages — which aims to speed up the delivery of web content to mobile devices. They say, "We began to experiment with an idea: could we develop a restricted subset of the things we'd use from HTML, that's both fast and expressive, so that documents would always load and render with reliable performance?" That subset is now encapsulated in AMP, their proof-of-concept. They've posted the code to GitHub and they're asking for help from the open source community to flesh it out. Their conclusions are familiar to the Slashdot crowd: "One thing we realized early on is that many performance issues are caused by the integration of multiple JavaScript libraries, tools, embeds, etc. into a page. This isn't saying that JavaScript immediately leads to bad performance, but once arbitrary JavaScript is in play, most bets are off because anything could happen at any time and it is hard to make any type of performance guarantee. With this in mind we made the tough decision that AMP HTML documents would not include any author-written JavaScript, nor any third-party scripts." They're seeing speed boosts anywhere from 15-85%, but they're also looking at pre-rendering options to make some content capable of loading instantaneously. Their FAQ has a few more details.

New submitter enterpriseITrocks writes: Computerworld reports that Windows 10 is running on 110 million devices, citing stats provided by Panos Panay, the chief of the Surface team. It's the first time since late August that Microsoft has provided usage stats for Win10 at a time when the new OS was running on 75 million machines. From the article: "Microsoft's 110 million described those running Windows 10, not downloads, the company confirmed. A spokeswoman declined to describe how the company tracks uptake, but presumably it does via Windows 10 activations, which it could easily tally from its logs."

jfruh writes: The average price of a 4GB DDR3 memory DIMM at the moment $18.50 — a price that's far lower than at this time last year. Why is it so cheap? The memory business tends to go in boom and bust cycles, but the free availability of Windows 10 means that fewer people are upgrading their PCs, reducing RAM demand. Analyst Avril Wu said, "Notebook shipments in the third quarter fall short of what is expected for a traditional peak season mainly because Windows 10 with its free upgrade plan negatively impacted replaced sales of notebooks to some extent rather than driving the demand for these products." And prices might stay low for another two years.

An anonymous reader writes: Last night Larry Wall unveiled the first development release of Perl 6, joking that now a top priority was fixing bugs that could be mistaken for features. The new language features meta-programming — the ability to define new bits of syntax on your own to extend the language, and even new infix operators. Larry also previewed what one reviewer called "exotic and new" features, including the sequence operator and new control structures like "react" and "gather and take" lists. "We don't want their language to run out of steam," Larry told the audience. "It might be a 30- or 40-year language. I think it's good enough."

An anonymous reader writes: A Microsoft research paper, titled 'Software Defined Batteries', outlines a radical charging alternative which uses a smart battery system to keep consumer-grade gadgets going for much longer than the current norm, by monitoring user habits. Making use of existing technologies, the engineers place multiple battery control under the duties of the operating system to create a software-defined approach optimized for different scenarios, such as word processing, email or video streaming.

New submitter DidgetMaster writes: Everyone knows that CPU registers are much faster than level1, level2, and level3 caches. Likewise, those caches are much faster than RAM; and RAM in turn is much faster than disk (even SSD). But the past 30 years have seen tremendous improvements in data access speeds at all these levels. RAM today is much, much faster than RAM 10, 20, or 30 years ago. Disk accesses are also tremendously faster than previously as steady improvements in hard drive technology and the even more impressive gains in flash memory have occurred. Is the 'gap' between the fastest RAM and the fastest disks bigger or smaller now than the gap was 10 or 20 years ago? Are the gaps between all the various levels getting bigger or smaller? Anyone know of a definitive source that tracks these gaps over time?

An anonymous reader writes: Over the past few years, Motorola has emerged as one of the best manufacturers for low-to-mid-range Android phones. Unlike many other major manufacturers, they keep their version of Android close to stock in order to keep OS updates flowing more easily. When they began marketing the Moto E 2015, updates were one of the features they trumpeted the loudest. But after the company published a list of devices that will continue to get updates, Android Police found the Moto E to be conspicuously absent. The phone launched on February 25, a mere 219 days ago. According to an official Motorola marketing video from launch day, "...we won't forget about you, and we'll make sure your Moto E stays up to date after you buy it."

MojoKid writes: Microsoft may have given you a free Windows 10 upgrade but it's not without some left over file clutter that some folks don't realize is left on a system after migration. It's not rocket science but there are a few key strategies to tidy up the file bloat an OS migration can sometimes leave behind and to further optimize an upgraded Windows 10 installation. The ability to roll back to your Windows 7 or 8.1 installation within 30 days is a very easily overlooked feature of the Windows 10 upgrade process. The feature is a lifesaver if you encounter issues, such as missing or incompatible drivers, and need to quickly recover without starting from scratch. This ability doesn't come without consequences, though. In order to offer this feature, Windows 10 is essentially keeping another completely separate Windows installation on your PC. This will need to go, once you've determined that you are sticking with Windows 10 and everything seems happy enough. These files are scattered throughout your system and include a number of hidden directories, with the bulk of them located in Windows.old and the hidden $Windows.~BT and $Windows.~WS directories.

minstrelmike writes: Mattel is coming out with a Talking Barbie designed by a huge team and pre-scripted with thousands of responses controlled by an AI, with designs to be your best friend. The design team remembers the "Math is hard" debacle of the 1990s and if a girl asks if she's pretty, Barbie will respond, "Yes. And you're smart, too." If she asks if Barbie believes in God, she says a person's beliefs are personal. And suggests talking to grownups about some problems. The linked New York Times' article ("Barbie Wants to Get to Know Your Child") even discusses trying to avoid edited vids on YouTube by scripting out words such as "cockroach."
