NAND Flash Density Surpasses HDDs', But Price Is Still a Sticking Point (computerworld.com) 185

Posted by timothy from the daddy-what-were-spinning-media-and-what-was-their-areal-density? dept.
Lucas123 writes: With the introduction of 3D or stacked NAND flash memory, non-volatile memory has for the first time surpassed that of hard disk drives in density. This year, Micron revealed it had demonstrated areal densities in its laboratories of up to 2.77 terabits per square inch (Tbpsi) for its 3D NAND. That compares with the densest HDDs of about 1.3Tbpsi. While NAND flash may have surpassed hard drives in density, it doesn't mean the medium has reached price parity with HDDs — nor will it anytime soon. One roadblock to price parity is the cost of revamping existing or building new 3D NAND fabrication plant, which far exceeds that of hard drive manufacturing facilities, according to market research firm Coughlin Associates. HDD makers are also preparing to launch even denser products using technologies such as heat assisted magnetic recording.

SpaceX Sets Feb. 24th Target Date For Next Launch 42

Posted by timothy from the safely-after-groundhog-day dept.
Rei writes: After some consternation about the pacing of Falcon 9 upgrades, SpaceX has announced that it plans to launch again from Cape Canaveral with a target date of February 24th. While the primary mission will be to place the SES-9 communications satellite in orbit, this will also mark their fourth attempt to land the first stage on an autonomous drone ship, after their last launch touched down softly but fell over when one leg failed to latch. SpaceX is working to significantly accelerate the rate of production and launches — they are reportedly moving the factory from 6-8 cores produced per year to 18 at present, and expect to reach 30 by the end of the year. After the upcoming launch, they expect to launch one rocket every two to three weeks.

Linux Kernel Patch Hints At At 32-Core Support For AMD Zen Chips 136

Posted by timothy from the more-like-seeds-than-cores dept.
New submitter Iamthecheese points to an article which says that a patch published on the Linux Kernel Mailing List indicates that AMD's forthcoming Zen processors will have as many as 32 cores per socket, but notes that while the article's headline says "Confirms," "the article text doesn't bear that out." Still, he writes, There are hints of such from last year. A leaked patch for the 14 nanometer AMD Zeppelin (Family 17h, Model 00h) reveals support for up to 32 cores. Another blog says pretty much the same thing. We recently discussed an announced 4+8 core AMD chip, but nothing like this.

Firefox Adopts a 6-8 Week Variable Release Schedule (mozilla.org) 249

Posted by timothy from the as-reports-warrant dept.
AmiMoJo writes: Four years ago Mozilla moved to a fixed-schedule release model, otherwise known as the Train Model, in which we released Firefox every six weeks to get features and updates to users faster. Now Mozilla is moving to a variable 6-8 week cycle, with the same number of releases per year but some flexibility to 'respond to emerging user and market needs' and allow time for holidays. The new release schedule looks like this:
  • 2016-01-26 – Firefox 44
  • 2016-03-08 – Firefox 45, ESR 45 (6 weeks cycle)
  • 2016-04-19 – Firefox 46 (6 weeks cycle)
  • 2016-06-07 – Firefox 47 (7 weeks cycle)
  • 2016-08-02 – Firefox 48 (8 weeks cycle)
  • 2016-09-13 – Firefox 49 (6 weeks cycle)
  • 2016-11-08 – Firefox 50 (8 weeks cycle)
  • 2016-12-13 – Firefox 50.0.1 (5 week cycle, release for critical fixes as needed)
  • 2017-01-24 – Firefox 51 (6 weeks from prior release)

The Performance of Ubuntu Linux Over the Past 10 Years (phoronix.com) 110

Posted by timothy from the so-it's-not-just-new-chips dept.
An anonymous reader writes: Tests were carried out at Phoronix of all Ubuntu Long-Term Support releases from the 6.06 "Dapper Drake" release to 16.04 "Xenial Xerus," looking at the long-term performance of (Ubuntu) Linux using a dual-socket AMD Opteron server. Their benchmarks of Ubuntu's LTS releases over 10 years found that the Radeon graphics performance improved substantially, the disk performance was similar while taking into account the switch from EXT3 to EXT4, and that the CPU performance had overall improved for many workloads thanks to the continued evolution of the GCC compiler.

CFQ In Linux Gets BFQ Characteristics 65

Posted by timothy from the omfg dept.
jones_supa writes: Paolo Valente from University of Modena has submitted a Linux kernel patchset which replaces CFQ (Completely Fair Queueing) I/O scheduler with the last version of BFQ (Budget Fair Queuing, a proportional-share scheduler). This patchset first brings CFQ back to its state at the time when BFQ was forked from CFQ. Paolo explains: "Basically, this reduces CFQ to its engine, by removing every heuristic and improvement that has nothing to do with any heuristic or improvement in BFQ, and every heuristic and improvement whose goal is achieved in a different way in BFQ. Then, the second part of the patchset starts by replacing CFQ's engine with BFQ's engine, and goes on by adding current BFQ improvements and extra heuristics." He provides a link to the thread in which it is agreed on this idea, and a direct link to the e-mail describing the steps.

Ask Slashdot: Fixing UVC Camera Issues Under Windows? 148

Posted by timothy from the you-get-to-keep-both-pieces dept.
Khyber writes: I bought some cheap Chinese camera glasses with built-in microphones. These are (supposedly) UVC cameras manufactured in 2015. Under Windows XP, these cameras are seen perfectly fine and work as web cameras; even the microphones work. Under Windows 7, the camera appears to install just fine, however I get the 'This device can perform faster if you connect to USB 2.0' (which it is connected to) and when I try to load it up with any camera viewer such as manycam or any chat program's built-in previewer, I cannot receive any video from the camera. I can get audio from the camera microphones under Windows 7, so I am wondering if the camera device is having problems enumerating as a USB 2.0 device due to some change in Windows 7 (which it doesn't seem to have issues doing under XP,) or if the UVC driver for Windows 7 is missing something in comparison to the one used for Windows XP. Anybody else had issues getting newer UVC cameras to work in newer operating systems?

AMD Launches Enthusiast A10-7860K APU, New Mainstream CPUs and Wraith Cooler (hothardware.com) 81

Posted by timothy from the but-I-already-have-a-computer dept.
MojoKid writes: AMD apparently wasn't done making announcements back at CES 2016. Today the company has shared news of new APUs, processors, fansink coolers, and motherboard updates. The company has been working with motherboard makers to enable a new wave of socket AM3+ and FM2+ motherboards with support for technologies like USB 3.1 (some with type-C and M.2 solid state drives (SSDs). Many of the updated motherboards are already available. AMD also has a trio of new APUs / processors coming down the pipe --the A10-7860K, the A6-7470K, and the Athlon X4 845. The Athlon X4 845 is a quad-core part, featuring four Excavator-class cores clocked at up to 3.8GHz. The processor has 2MB of L2 cache, 8 PCIe 3.0 lanes, and a TDP of 65W, but no built-in graphics. The A6-7470K is a dual Steamroller-core APU (clocked at up to 4GHz), with 8 GPU cores (at up to 800MHz), 1MB of L2 cache, 16 PCIe lanes, and a 65W TDP. The A10-7860K is a little beefier with four Steamroller cores (clocked up to 4GHz), with 8 GPU cores (clocked up to 757MHz), 1MB of L2 cache, 16 PCIe lanes, and a 65W TDP. Both the 7860K and 7470K are unlocked for more flexible overclocking. Finally, the FX-8370 bundled with AMD's new Wraith cooler will be arriving today at the same price point as the previous edition. According to AMD, the Wraith cooler offers 24% more surface area than the previous PIB cooler and the fan pushes 34% more air.

Windows 10 Now a 'Recommended Update' For Windows 7 and 8.1 Users (betanews.com) 581

Posted by timothy from the better-look-into-that dept.
Mark Wilson writes: Microsoft has been accused of pushing Windows 10 rather aggressively, and the company's latest move is going to do nothing to silence these accusations. For Windows 7 and Windows 8.1 users, Windows 10 just became a 'recommended update' in Windows Update.

This is a change from the previous categorization of the upgrade as an 'optional update' and it means that there is renewed potential for unwanted installations. After the launch of Windows 10, there were numerous reports of not only the automatic download of OS installation files, but also unrequested upgrades. The changed status of the update means that, on some machines, the installation of Windows 10 could start automatically.

Triple M.2 NVMe RAID-0 Testing Proves Latency Reductions 73

Posted by timothy from the listen-to-your-intuition-luke dept.
Vigile writes: The gang over at PC Perspective just posted a story that looks at a set of three M.2 form factor Samsung 950 Pro NVMe PCIe SSDs in a RAID-0 array, courtesy of a new motherboard from Gigabyte that included three M.2 slots. The pure bandwidth available in this configuration is amazing, breaching 3.3 GB/s on reads and 3.0 GB/s on writes. But what is more interesting is a new testing methodology that allows for individual storage IO latency capturing, giving us a look at performance of SSDs in all configurations. What PC Perspective proved here is that users often claiming that RAIDs "feel faster" despite a lack of bandwidth result to prove it, are likely correct. Measurements now show that the latency of IO operations improves dramatically as you add drives to an array, giving a feeling of "snappiness" to a system beyond even what a single SSD can offer. PC Perspective's new testing demonstrates the triple RAID-0 array having just 1/6th of the latency of a single drive.

Samsung Begins Mass Production of World's Fastest DRAM (hothardware.com) 65

Posted by Soulskill from the better-harder-faster-stronger dept.
MojoKid writes: Late last year marked the introduction of High Bandwidth Memory (HBM) DRAM courtesy of AMD's Fury family of graphics cards, each of which sports 4GB of HBM. HBM allows these new AMD GPUs to tout an impressive 512GB/sec of memory bandwidth, but it's also just the first iteration of the new memory technology. Samsung has just announced that it has begun mass production of HBM2. Samsung's 4GB HBM2 package is built on a 20 nanometer process. Each package contains four 8-gigabit core dies built on top of a buffer die. Each 4GB HMB2 package is capable of delivering 256GB/sec of bandwidth, which is twice that of first generation HBM DRAM. In the example of NVIDIA's next gen GPU technology, code named Pascal, the new GPU will utilize HBM2 for its frame buffer memory. High-end consumer-grade Pascal boards will ship with 16GB of HBM2 memory (in four, 4GB packages), offering effective memory bandwidth of 1TB/sec (256GB/sec from each HMB2 package). Samsung is also reportedly readying 8GB HBM2 memory packages this year.

How OpenGL Graphics Card Performance Has Evolved Over 10 Years (phoronix.com) 115

Posted by Soulskill from the spoiler:-it's-gotten-better dept.
An anonymous reader writes: A new report at Phoronix looks at the OpenGL performance of 27 graphics cards from the GeForce 8 through GeForce 900 series. Various Ubuntu OpenGL games were tested on these graphics cards dating back to 2006, focusing on raw performance and power efficiency. From oldest to newest, there was a 72x increase in performance-per-Watt, and a 100x increase in raw performance. The NVIDIA Linux results arrive after doing a similar AMD comparison from R600 graphics cards through the R9 Fury. However, that analysis found that for many of the older graphics cards, their open-source driver support regressed into an unworkable state. For the cards that did work, the performance gains were not nearly as significant over time.

Fedora Linux Might Drop Incremental Upgrades (happyassassin.net) 91

Posted by Soulskill from the how-to-save-an-hour-a-year dept.
prisoninmate writes: As you might know, Fedora and many other GNU/Linux distributions require users to do an incremental upgrade when attempting to move from an older version of the operating system to the most recent one. For example, if you want to upgrade from Fedora 21 to Fedora 23, you will have first to upgrade to Fedora 22. Lately, Fedora upgrades have become more stable and reliable, mostly because of some brand-new technologies, such as the DNF package manger. Fedora's Adam Williamson theorizes about an innovative method that might support official upgrade of the Fedora Linux operating system across two releases in the future.

Netgear Nighthawk X8 AC5300 Router With Active Antennas Tested (hothardware.com) 85

Posted by timothy from the fewer-dollars-but-no-wires dept.
MojoKid writes: Netgear recently launched the Nighthawk X8 router, which is part of a new round of second-gen wireless AC devices dubbed "Wave 2", carrying the AC5300 moniker. Instead of using a 3x3 configuration with six antennae, this router offers a 4x4 configuration, with four internal antennae and four active external antennae, each with their own blue LEDs to signal their active state. The actual amplifiers are on the antennae themselves, rather than down on the main board, helping to boost the signal and minimize crosstalk and loss associated with modern PCB circuitry. Each 5GHz radio is able to broadcast at 2.1Gbps compared to 1.3Gbps on Gen 1 devices, and the bandwidth on the 2.4GHz channel is also increased from 600Mb/s on Gen 1 devices to 1GB/s. When you take both 5GHz channels at 2,100Mb/s and add it to the 1,000Mb/s on the 2.4GHz channel, you end up with a number around 5,300Mb/s, hence the branding. Performance-wise, the Nighthawk X8 is one of the fastest Wi-Fi routers on the market currently. However, its hefty price point might be hard to justify for most mainstream users. Enthusiasts and small office/home office users looking for ultimate range on a 5GHz channel with lots of clients connected will appreciate this routers throughput and power, however.

'Get Windows 10' Turns Itself On and Nags Win 7 and 8.1 Users Twice a Day (infoworld.com) 720

Posted by Soulskill from the no-means-no-microsoft dept.
LichtSpektren writes: As you may recall, Microsoft has delivered KB3035583 as a 'recommended update' to users of Windows 7 and 8.1. What this update does is install GWX ("Get Windows 10"), a program which diagnoses the system to see if it is eligible for a free upgrade to Windows 10, and if so, asks the user if they would like to upgrade (though recently, the option to decline has been removed). Some users have gotten around this by editing Windows Registry values for "AllowOSUpgrade", "DisableOSUpgrade", "DisableGWX", and "ReservationsAllowed" in order to disable the prompt altogether. This advice was endorsed by Microsoft on their support forums.

According to a report by Woody Leonhard at InfoWorld, the newest version of the KB3035583 update includes a background process which scans the system's Windows Registry twice a day to see if the values for the four aforementioned registry inputs were manually edited to disable the upgrade prompt. If they were, the process will alter the values, silently re-download the Windows 10 installation files (about 6 GB in total), and prompt the user to upgrade.

PostgreSQL 9.5 Does UPSERT Right (thenewstack.io) 105

Posted by timothy from the oh-that's-upsert dept.
joabj writes: For years, PostgreSQL users would ask when their favorite open source database system would get the UPSERT operator, which can either insert an entry or update it if a previous version already existed. Other RDMS have long offered this feature. Bruce Momjian, one of the chief contributors to PostgreSQL, admits to being embarrassed that it wasn't supported. Well, PostgreSQL 9.5, now generally available, finally offers a version of UPSERT and users may be glad the dev team took their time with it. Implementations of UPSERT on other database systems were "handled very badly," sometimes leading to unexpected error messages Momjian said. Turns out it is very difficult to implement on multi-user systems. "What is nice about our implementation is that it never generates an unexpected error. You can have multiple people doing this, and there is very little performance impact," Momjian said. Because it can work on multiple tables at once, it can even be used to merge one table into another.

Coast-To-Coast Autonomous Tesla Trips 2-3 Years Out, Says Elon Musk (google.com) 259

Posted by timothy from the which-ones-are-stolen? dept.
Jalopnik reports that Elon Musk's predicted window for being able (for Tesla owners, that is) to call up your autonomous car and have it find its own way from New York to California, or vice versa, is astonishingly close: 24-36 months from now. From the article: As far as the summoning feature is concerned, Tesla plans for the 33-foot range to greatly expand—soon. Within two years, Musk predicted that owners will be able to summon their car from across the country. “If you’re in New York and your car is in Los Angeles, you can summon your car to you from your phone and tell the car to find you,” Musk said. “It’ll automatically charge itself along the journey. I might be slightly optimistic about that, but not significantly optimistic.” In getting from one place to another, Musk said autopilot “is better than human in highway driving, or at least it will be soon with machine learning.” If it’s not already better than human, Musk said it will be within the coming months. But right now, Musk said the car still needs a human around, just in case. “The car currently has sensors to achieve that cross-country goal,” Musk said. “But you’d need more hardware and software, you’d need more cameras, more radars, redundant electronics, redundant power buses and that sort of thing.
