Google's Effort To Speed Up the Mobile Web ( 88

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.

Microsoft Claims 110M Devices Now Run Windows 10 ( 147

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."

Why Is RAM Suddenly So Cheap? It Might Be Windows 208

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.

Larry Wall Unveils Perl 6.0.0 157

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."

Software Defined Smart Battery Arrays Extend Laptop Life 40

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.

Ask Slashdot: Is the Gap Between Data Access Speeds Widening Or Narrowing? 91

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?

Motorola Marketed the Moto E 2015 On Promise of Updates, Stops After 219 Days 123

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."

How To Clean the Cruft Left By a Windows 10 Upgrade 205

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.

What's New In GNOME 3.18 170

prisoninmate writes: In this release, GNOME improves the general user experience for users and new developers alike. GNOME 3.18 adds a feature called "Automatic Brightness," which, when enabled, it will make use of your laptop's light sensor to dim or increase the screen's brightness depending on the surrounding lighting. GNOME 3.18 also improves the touch screen experience, especially when selecting and modifying text, implements a new view in the Nautilus (Files) sidebar, which collects all the remote and internal locations in a single place.

Barbie Gets a Brain 235

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."

Microsoft Is Downloading Windows 10 Without Asking 867

New submitter christhedj writes with a story at The Inquirer, according to which: Microsoft, having learned nothing from Apple and the U2 album, have started downloading Windows 10 as part of Patch Tuesday for Windows 7 and 8 users. For people on a 32GB flash drive tablet, that's a big chunk of space taken up with something that they didn't ask for. Microsoft admits to doing this, but users are not happy. Way to look needy, Microsoft.

AMD Radeon R9 Nano: 6 Inches Of High-Priced, High-Performance Graphics 26

Vigile writes: Back when AMD announced it would be producing an even smaller graphics card than the Fury X, but based on the same full-sized Fiji GPU, many people wondered just how they would be able to pull it off. Using 4096 stream processors, a 4096-bit memory bus with 4GB of HBM (high bandwidth memory) and a clock speed rated "up to" 1000 MHz, the new AMD Radeon R9 Nano looked to be an impressive card. Today, PC Perspective has a review of the R9 Nano and though there are some quirks, including pronounced coil whine and a hefty $650 price tag, it offers nearly the same performance as the non-X Radeon R9 Fury card at 100 watts lower TDP! It is able to do that by dynamically adjusting the clock speed from ~830 MHz to 1000 MHz depending on the workload, always maintaining a peak power draw of just 175 watts. All of this is packed into a 6 inch PCB — smaller than any other enthusiast class GPU to date, making it a perfect pairing for SFF cases that demand smaller components. The R9 Nano is expensive though with the same asking price as AMD's own R9 Fury X and the GeForce GTX 980 Ti. Readers have also submitted links to reviews at Hot Hardware and Tom's Hardware.

Windows Telemetry Rolls Out 527

ihtoit writes: Last week came the warning, now comes the roll out. One of the most most controversial aspects of Windows 10 is coming to Windows 7 and 8. Microsoft has released upgrades which enable the company to track what a user is doing. The updates – KB3075249, KB3080149 and KB3068708 – all add "customer experience and diagnostic telemetry" to the older versions. gHacks points out that the updates will ignore any previous user preferences reporting: "These four updates ignore existing user preferences stored in Windows 7 and Windows 8 (including any edits made to the Hosts file) and immediately starts exchanging user data with and"

Intel Launches Onslaught of Skylake CPUs For Laptops, Hybrids and Compute Stick 54

MojoKid writes: Intel is following up on its Skylake launch bonanza by opening the floodgates on at least two dozen SKUs mostly covering the mobile sector. The company is divvying up the range into four distinct series. There's the Y-Series, which is dedicated to 2-in-1 convertibles, tablets, and Intel's new Compute Stick venture. Then there's the U-Series, which is aimed at thin and light notebooks and "portable" all-in-one machines. The H-Series is built for gaming notebooks and mobile workstations, while the S-Series is designated for desktops, all-in-one machines, and mini PCs. Also, the Y-Series that was previously known as simply the Core M, (the chip found in products like the 12-inch Apple MacBook and Asus Transformer Book Chi T300) is now expanding into a whole family of processors. There will be Core m3, Core m5, and Core m7 processors, similar to Intel's Core i3, Core i5, and Core i7 CPU models in other desktop and notebook chips.

LLVM 3.7 Delivers OpenMP 3.1 Support, ORC JIT API, New Optimizations 84

An anonymous reader writes: LLVM 3.7 was released today as the newest six-month update. LLVM 3.7 has OpenMP 3.1 support via Clang, a new On-Request Compilation JIT API, the Berkeley Packet Filter back-end was added, the AMDGPU back-end now supports OpenGL 4.1 when paired with Mesa 11.0, and many other functional changes. Early benchmarks against GCC show its performance quite competitive with GCC5, even superior in some workloads, and should be more competitive in scientific applications with there now being OpenMP support.

Video Mozilla Project Working on Immersive Displays (Video) 47

Yes, it's 3-D, and works with the Firefox browser. But that's not all. The MozVR virtual reality system is not just for Firefox, and it can incorporate infrared and other sensors to give a more complete picture than can be derived from visible light alone. In theory, the user's (client) computer needs no special hardware beyond a decent GPU and an Oculus Rift headset. Everything else lives on a server.

Is this the future of consumer displays? Even if not, the development is fun to watch, which you can start doing at -- and if you're serious about learning about this project you may want to read our interview transcript in addition to watching the video, because the transcript contains additional information.
