Samsung SSD On a Tiny M.2 Stick Is Capable of Read Speeds Over 2GB/sec 72

MojoKid writes: Samsung has just announced its new SM951-NVMe SSD, the industry's first NVMe SSD to employ an M.2 form-factor. Samsung says the new gumstick style drive is capable of sequential read and write speeds of 2,260 MB/sec and 1,600 MB/sec respectively. Comparable SATA-based M.2 SSDs typically can only push read/write speeds of 540 MB/sec and 500 MB/sec, while most standard PCIe versions muster just north of 1GB/sec. The Samsung SM951-NVMe's performance is actually very comparable to the Intel SSD 750 Series PCIe x4 card but should help kick notebook performance up a notch in this common platform configuration.

New Samsung SSD 840 EVO Read Performance Fix Coming Later This Month 72

An anonymous reader writes: The Samsung SSD 840 EVO read performance bug has been on the table for over six months now. Initially Samsung acknowledged the issue fairly quickly and provided a fix only a month after the news hit the mainstream tech media, but reports of read performance degradation surfaced again a few weeks after the fix had been released, making it clear that the first fix didn't solve the issue for all users. Two months ago Samsung announced that a new fix is in the works and last week Samsung sent out the new firmware along with Magician 4.6 for testing, which will be available to the public later this month.

Fifty Years of Moore's Law 101

HughPickens.com writes: IEEE is running a special report on "50 Years of Moore's Law" that considers "the gift that keeps on giving" from different points of view. Chris Mack begins by arguing that nothing about Moore's Law was inevitable. "Instead, it's a testament to hard work, human ingenuity, and the incentives of a free market. Moore's prediction may have started out as a fairly simple observation of a young industry. But over time it became an expectation and self-fulfilling prophecy—an ongoing act of creation by engineers and companies that saw the benefits of Moore's Law and did their best to keep it going, or else risk falling behind the competition."

Andrew "bunnie" Huang argues that Moore's Law is slowing and will someday stop, but the death of Moore's Law will spur innovation. "Someday in the foreseeable future, you will not be able to buy a better computer next year," writes Huang. "Under such a regime, you'll probably want to purchase things that are more nicely made to begin with. The idea of an "heirloom laptop" may sound preposterous today, but someday we may perceive our computers as cherished and useful looms to hand down to our children, much as some people today regard wristwatches or antique furniture."

Vaclav Smil writes about "Moore's Curse" and argues that there is a dark side to the revolution in electronics for it has had the unintended effect of raising expectations for technical progress. "We are assured that rapid progress will soon bring self-driving electric cars, hypersonic airplanes, individually tailored cancer cures, and instant three-dimensional printing of hearts and kidneys. We are even told it will pave the world's transition from fossil fuels to renewable energies," writes Smil. "But the doubling time for transistor density is no guide to technical progress generally. Modern life depends on many processes that improve rather slowly, not least the production of food and energy and the transportation of people and goods."

Finally, Cyrus Mody tackles the question: what kind of thing is Moore's Law? "Moore's Law is a human construct. As with legislation, though, most of us have little and only indirect say in its construction," writes Mody. "Everyone, both the producers and consumers of microelectronics, takes steps needed to maintain Moore's Law, yet everyone's experience is that they are subject to it."

Sharp Announces 4K Smartphone Display 152

An anonymous reader writes: Japanese electronics giant Sharp has announced production of 5.5" displays with 4K (3840 x 2160) resolution. They'll hit the market next year. The display will have a pixel density of 806 PPI. It's not known yet which smartphone makers will build devices with these screens. The displays cost significantly more than a more typical 1080p or 1440p display, so they'll probably only make it into high-end phones. On the other hand, this will help to drive down prices for lower-resolution displays, so it could indirectly benefit everybody.

Killer Robots In Plato's Cave 91

Lasrick writes Mark Gubrud writes about the fuzzy definitions used to differentiate autonomous lethal weapons from those classified as semi-autonomous: "After all, if the only criterion is that a human nominates the target, then even The Terminator...might qualify as semi-autonomous." Gubrud wants a ban against autonomous hunter-killer weapons like the Long-Range Anti-Ship Missile and the canceled Low-Cost Autonomous Attack System, and vague definitions surrounding autonomous and semi-autonomous weapons that will allow weapons that should be classified as autonomous but aren't. Existing definitions draw a "distinction without a difference" and "will not hold against the advance of technology." Gubrud prefers a definition that reduces autonomy to a simple operational fact, an approach he calls "autonomy without mystery." In the end, Gubrud writes, "Where one draws the line is less important than that it is drawn somewhere. If the international community can agree on this, then the remaining details become a matter of common interest and old-fashioned horse trading."

Transforming Robot Gets Stuck In Fukushima Nuclear Reactor 99

An anonymous reader writes with more bad news for the people still dealing with the Fukushima nuclear accident. "The ability to change shape hasn't saved a robot probe from getting stuck inside a crippled Japanese nuclear reactor. Tokyo Electric Power will likely leave the probe inside the reactor housing at the Fukushima Dai-ichi complex north of Tokyo after it stopped moving. On Friday, the utility sent a robot for the first time into the primary containment vessel (PCV) of reactor No. 1 at the plant, which was heavily damaged by the 2011 earthquake and tsunami in northern Japan. 'The robot got stuck at a point two-thirds of its way inside the PCV and we are investigating the cause,' a Tokyo Electric spokesman said via email. The machine became stuck on Friday after traveling to 14 of 18 planned checkpoints."

Report: Chinese Government Plans To Put 3D Printers In All Elementary Schools 99

InfiniteZero writes The Chinese government has a new plan to install a 3D printer in each of its approximately 400,000 elementary schools over the next two years. Education is probably one of the areas that will benefit the most from 3D printers in the long run. The problem though is getting the machines into the schools in the first place. With prices generally ranging from $400 to $3,000 for typical desktop 3D printers, they are not cheap, and with budgets within many school districts running dry, both in the United States and overseas, the unfortunate fact is that many schools simply can’t afford them, not to mention the materials and time it takes to train teachers to use them.

Ask Slashdot: Best Medium For Storing Data To Survive a Fire (or Other Disaster) 446

First time accepted submitter aka_bigred writes Every year as I file my taxes, I replicate my most important financial data (a couple GB of data) to store an offline copy in my fire-rated home safe. This gets me thinking about what the most reliable data media would be to keep in my fire-rated home safe.

CDs/DVDs/tapes could easily melt or warp rendering them useless, so I'm very hesitant to use them. I've seen more exotic solutions that let you print your digital data to paper an optically re-import it later should you ever need it, but it seems overly cumbersome and error prone should it be damaged or fire scorched. That leaves my best options being either a classic magnetic platter drive, or some sort of solid state storage, like SD cards, USB flash drives, or a small SSD. The problem is, I can't decide which would survive better if ever exposed to extreme temperatures, or water damage should my house burn down.

Most people would just suggest to store it in "the cloud", but I'm naturally averse to doing so because that means someone else is responsible for my data and I could lose it to hackers, the entity going out of business, etc. Once it leaves my home, I no longer fully control it, which is unacceptable. My thought being "they can't hack/steal what they can't physically access." What medium do other Slashdot users use to store their most important data (under say 5GB worth) in an at-home safe to protect it from fire?

Google Battles For Better Batteries 44

An anonymous reader writes: The Wall Street Journal reports that Google's X research lab has joined the quest for better batteries. The company has at least 20 projects that depend on batteries, from Google Glass to self-driving cars and drones. Thus, it makes sense for them to try developing new battery technology. "At Google, Dr. Bhardwaj's group is trying to advance current lithium-ion technology and the cutting-edge solid-state batteries for consumer devices. ... In a February presentation to an industry conference, Dr. Bhardwaj described how solid-state, thin-film batteries could be used in smartphones and other mobile devices that are thinner, bendable, wearable and even implantable in the human body. ... For the contact lens, the technology is safer because it doesn't use flammable electrolyte liquid, Dr. Bhardwaj's presentation explained."

LG Split Screen Software Compromises System Security 187

jones_supa writes: The Korean electronics company LG ships a split screen tool with their ultra wide displays. It allows users to slice the Windows desktop into multiple segments. However, installing the software seriously compromises security of the particular workstation. The developers required administrator access for the software, but apparently they hacked their way out. The installer silently disables User Account Control, and enables a policy to start all applications as Administrator. In the article there is also a video presentation of the setup procedure. It is safe to say that no one should be running this software in its current form.

220TB Tapes Show Tape Storage Still Has a Long Future 229

alphadogg writes: IBM and Fujifilm have figured out how to fit 220TB of data on a standard-size tape that fits in your hand, flexing the technology's strengths as a long-term storage medium. The prototype Fujifilm tape and accompanying drive technology from IBM labs packs 88 times as much data onto a tape as industry-standard LTO-6 systems using the same size cartridge, IBM says. LTO6 tape can hold 2.5TB, uncompressed, on a cartridge about 4 by 4 inches across and 2 centimeters thick. The new technologies won't come out in products for several years.

Google Lollipop Bricking Nexus 5 and Nexus 7 Devices 179

First time accepted submitter Zape (303550) writes The Lollipop update has turned sour for me and several other Nexus 7, Gen 2 (and Nexus 5) owners. It seems that I'm not alone in having my tablet boot to the Google Logo since a couple of days after updating to Android 5.0.2. Now Nexus 5 owners are reporting a reboot loop in Android 5.1. My device, like many others, is a couple of months out of warranty, but worked great until the latest OTA update from Google. They branded it, and they updated it, but Google claims it is between the buyers and ASUS, the manufacturer.

The Myth of Going Off the Power Grid 281

Lasrick writes: Dawn Stover uses Elon Musk's announcement that Tesla will soon be unveiling plans for a battery that could power your home as a starting point to explore the idea that "going off the grid" is going to solve climate change. "The kind of in-house energy storage he is proposing could help make renewables a bigger part of the global supply. But headlines announcing that a Tesla battery 'could take your home off the grid' spread misconceptions about what it takes to be self-sufficient — and stop global warming." Stover worries that shifting responsibility for solutions to climate change from governments to individuals creates an 'every-man-for-himself' culture that actually works against energy solutions and does little to reduce overall greenhouse gas emissions. Instead, "smart grid" technology would be much more efficient: "With a smarter grid, excess electricity generated by solar panels and wind turbines could be distributed to a network of on-the-grid home and car batteries. Some utilities have also experimented with using home water heaters as an economical substitute for batteries."

Video Another 'Draw Your Own Circuits' System at SXSW (Video) 27

While Timothy Lord was at SXSW, he chatted with Yuki Nishida of AgIC and learned about the company's conductive ink products. But AgIC wasn't the only company at SXSW showing off conductive ink. You could also meet the Electroninks people and see their Circuit Scribe product, which had a Kickstarter campaign a while back that raised $574,425.

This kind of product seems to be attractive to the kind of people who fund Kickstarter projects, and this bunch seems to have good resumes and some interesting, well thought-out products. There is apparently room in the 'draw circuits and learn electrical basics' market for both AgIC and Electroninks -- and probably for another dozen competitors, too.

US Blocks Intel From Selling Xeon Chips To Chinese Supercomputer Projects 229

itwbennett writes: U.S. government agencies have stopped Intel from selling microprocessors for China's supercomputers, apparently reflecting concern about their use in nuclear tests. In February, four supercomputing institutions in China were placed on a U.S. government list that effectively bans them from receiving certain U.S. exports. The institutions were involved in building Tianhe-2 and Tianhe-1A, both of which have allegedly been used for 'nuclear explosive activities,' according to a notice (PDF) posted by the U.S. Department of Commerce. Intel has been selling its Xeon chips to Chinese supercomputers for years, so the ban represents a blow to its business.

Intel's Core M Performance Is Erratic Between Devices 85

An anonymous reader writes: AnandTech noticed some odd performance disparities with Intel's Core M CPU, a chip designed to bring high-powered processing to thin, fan-less devices. After investigating, they found that how OEMs build their laptops and tablets has a far greater effect on Core M performance than it does for other chips. "When an OEM designs a device for Core M, or any SoC for that matter, they have to consider construction and industrial design as well as overriding performance. ... This, broadly speaking, gives the OEM control over several components that are out of the hands of the processor designers. Screen size, thickness, industrial design, and skin temperature all have their limits, and adjusting those knobs opens the door to slower or faster Core M units, depending on what the company decides to target.

In the Core M units that we have tested at AnandTech so far this year, we have seen a variety of implementations with and without fans and in a variety of form factors. But the critical point of all of this comes down to how the OEM defines the SoC/skin temperature limitations of the device, and this ends up being why the low-end Core M-5Y10 can beat the high-end Core M-5Y71, and is a poignant part of our tests. Simply put, if the system with 5Y10 has a higher SoC/skin temperature, it can stay in its turbo mode for longer and can end up outperforming a 5Y71, leading to some of the unusual results we've seen so far."

Has Google Indexed Your Backup Drive? 121

itwbennett writes Depending on how you've configured the device, your backup drive may have been indexed by Google, making some seriously personal information freely available online to anyone who knows what they're looking for. Using a few simple Google searches, CSO's Steve Ragan discovered thousands of personal records and documents online, including sales receipts with credit card information and tax documents with social security numbers. In all cases, the files were exposed because someone used a misconfigured device acting as a personal cloud, or FTP (File Transfer Protocol) was enabled on their router.

Virtual Desktop Makes Windows OS Oculus Rift-Capable 47

An anonymous reader writes Virtual Desktop is a free program that makes the Windows operating system compatible with the Oculus Rift VR headset. To the surprise of some, plugging the Oculus Rift into a computer doesn't result in a native view of the OS, meaning that users have to put on and take off the headset as they move from one VR-specific app to the next. If you want to use typical Windows programs—like Photoshop, Firefox, or Microsoft Office—no dice! That's where Virtual Desktop comes in, enabling the entire Windows desktop, and any application that can run on it, to be seen through the Oculus Rift. It also works as a bridge between VR-specific applications, allowing you to move from one to the next without ever taking off the headset. The latest version released today includes voice commands for launching VR games, global monitor mirroring, performance improvements, and is built against the latest Oculus Rift SDK.

1+ Year Running Arch Linux On a Lenovo Yoga 2 Chronicled 74

New submitter KeithCu writes with a lengthy explanation of the joys (and just a handful of glitches) he's had in running Arch Linux on his ultraportable, a Lenovo Yoga 2. Other than the hardware-specific issues, I've been amazed by how well Arch Linux works, given that it doesn't have release cycles, or a big team with a lot of money supporting and marketing it. I've heard only 30 developers maintain the core Arch packages, with most of them having a full-time job doing something else! At the same time, it shouldn't be a total surprise things work so well, because free software doesn't just fall off a turnip truck. Not many reviews feature pictures of a laptop charred from building LibreOffice.
