storagedude writes "As more and more companies move to virtualized, or software-defined, data centers, cost savings might not be one of the benefits. Sure, utilization rates might go up as resources are pooled, but if the end result is that IT resources become easier for end users to access and provision, they might end up using more resources, not less. That's the view of Peder Ulander of Citrix, who cites the Jevons Paradox, a 150-year-old economic theory that arose from an observation about the relationship between coal efficiency and consumption. Making a resource easier to use leads to greater consumption, not less, says Ulander. As users can do more for themselves and don't have to wait for IT, they do more, so more gets used. The real gain, then, might be that more gets accomplished as IT becomes less of a bottleneck. It won't mean cost savings, but it could mean higher revenues."
hypnosec writes "Samsung has announced the world's fastest NAND memory that supports the eMMC 5.0 standard. The new memory chips are based on 10nm class NAND flash technology and feature an interface speed of 400MB/s. Further, the 32GB and 64GB densities have a random read and write speed of 7,000 IOPS (inputs/outputs per second) while the sequential read and write speeds stand at 250MB/s and 90MB/s respectively. The chips will provide for better multitasking, HD video recording, gaming and browsing."
kkleiner writes "An artistic robotic system named e-David has been developed that produces paintings that appear to be created by humans. Using an iterative process of brush strokes and image comparison, e-David's assembly line welder arm can paint in up to 24 colors and add shading where needed. The robot even cleans its five brushes along the way, according to University of Konstanz researchers who developed the system as an exercise in machine learning."
Via Engadget comes the news that Google's latest (and quickly sold-out) toy, the Chromecast, may soon be hacked out of one-trick-pony status; just a few days after it came out, the folks at GTV Hacker have successfully turned their attention to the Chromecast, and managed to exploit the device's bootloader and spawn a root shell. Some interesting findings, as explained in their blog post: "[I]t’s actually a modified Google TV release, but with all of the Bionic / Dalvik stripped out and replaced with a single binary for Chromecast. Since the Marvell DE3005 SOC running this is a single core variant of the 88DE3100, most of the Google TV code was reused. So, although it’s not going to let you install an APK or anything, its origins: the bootloader, kernel, init scripts, binaries, are all from the Google TV. We are not ruling out the ability for this to become a Google TV 'stick.'"
Not all 3-D printed guns can encounter the smooth, uneventful success of Cody Wilson's Liberator; Daniel_Stuckey writes with this excerpt: "A Canadian has just fired the first shot from his creation, 'The Grizzly,' an entirely 3D-printed rifle. In that single shot, CanadianGunNut (his name on the DefCad forum), or "Matthew," has advanced 3D-printed firearms to yet another level. Sort of: According to his video's description, the rifle's barrel and receiver were both damaged in that single shot."
An anonymous reader writes "I'm an Engineer with a need for 3 large monitors on the one PC. I want to run them as 'one big desktop' so I can drag windows around between all three monitors (Windows XP style). I run Debian and an nVidia NVS450. Currently I have been able to do what I want by using Xinerama which is painfully slow (think 1990s), or using TwinView which is hardware accelerated but only supports 2 monitors. I can live without 3D performance, but I need a hardware accelerated 2D desktop at the minimum. What are my options? I will happily give up running X and run something else if I need to (although I would like to keep using Xfce — but am open to anything). I am getting so desperate that I am starting to think of running Windows on my box, but that would be painful in so many other ways given my work environment revolves around the Linux toolset."

First time accepted submitter MrClappy writes "I manage the network for a defense contractor that needs a cloud-based storage service and am having a lot of trouble finding an appropriate solution that meets our requirements. We are currently using DropBox and I am terrified of seeing another data leak like last year. Some of our data is classified under International Traffic in Arms Regulations (ITAR) which requires that all data to remain inside the US, including any cloud storage or redundant backups. We tried using Box as a more secure replacement but ended up canceling the service due to lack of functionality; 40,000 file sync limit, Linux-based domain controller compatibility issues and the fact that the sync application does not work while our computers are locked (which is an explicit policy for my users). I've been calling different companies and just can't seem to find a decent solution. Unless I'm severely missing something, I'm just blown away that no one offers this functionality with today's tech capabilities. Am I wrong?"
adeelarshad82 writes "While it's more limited than the Roku 3 and by no means Google's answer to Airplay, Chromecast sets itself apart from other similar products simply based on its price and potential of bringing Internet HDTV streaming to many more people than before. Priced at only $35, it's a direct stick that plugs into your HDTV's HDMI port and lets you stream media from Netflix, YouTube, and Google Play through your smartphone, tablet, or notebook. Unlike the Roku Stick, it uses a separate micro-USB port instead of MHL to power it. This on one hand means you need to run a cable from the stick to a USB port, making it much less neat than it would seem. On the other hand, it means the stick works with any HDTV, whether it has an MHL-capable HDMI port or not. Once connected, the setup itself is fairly simple and entirely app-controlled. Past the setup, your streaming content choices are currently limited, though Google released an API for the Chromecast, so more apps could support it in the future. For now Android users can stream media from Google Play Movies and Music, as well as Netflix and YouTube whereas iOS users can watch Netflix and YouTube via the Chromecast. From a computer, users can stream media from Netflix, YouTube, Google Play, and Chrome. Unlike Apple TV and AirPlay, Chromecast doesn't let you stream your locally stored media. In fact Google Play Music gives an error message when you try to play music you loaded on your device yourself and not through the Google Play store. All in all, at $35 it's the most affordable way to access online media services on your HDTV." El Reg also got their hands on one. Alas, one perk of grabbing the Chromecast is gone: Google ended the free three month Netflix bundle that was worth almost as much as the cost of the Chromecast itself after sales were much higher than expected (so high it looks like they ran out of them after only a day). Update: 07/26 21:20 GMT by U L : iFixIt posted a teardown of the Chromecast.
An anonymous reader writes "Apple's had a small, very secretive office in Cambridge, MA for a few months now. And we finally know what they're doing: Building a team that works on speech technology for Siri. Sure, it's interesting for Apple to have a remote engineering team. And hiring from MIT is a no-brainer. But here's why this is a bigger deal: Apple has always relied on Nuance, a Boston-area company, for the speech-recognition technology behind Siri. By branching out with its own speech team — stocked with former Nuance scientists, no less — Apple could very well be signaling a move away from relying on Nuance for this core technology. And the speech wars are just heating up: Microsoft and Amazon both have speech engineering offices in the Boston area too."
A few days ago, the CyanogenMod teamed teased a new project named Nemesis, a series of planned improvements to the user interface. An anonymous reader writes with news of the first part: a new camera application designed to replace the neglected stock Android camera app. From the article: "As cameras and camera software becomes an increasingly important part of our mobile experience, a great photography experience on your smartphone can make all the difference. The CyanogenMod project has decided to take smartphone photography a lot more seriously with the release of Focal, and all new camera app for CM users everywhere." Android Police also has an early look with screenshots. The menu system in particular looks a lot nicer to use than the current cumbersome interface to white balance/exposure/scene settings. Focal should be merged into nightly releases soon.
First time accepted submitter ormembar writes "I have a laptop with a 1 TB hard disk. I use rsync to perform my backups (hopefully quite regularly) on an external 1 TB hard disk. But, with such a large hard disk, it takes quite some time to perform backups because rsync scans the whole disk for updates (15 minutes in average). Does it exist somewhere a kind of asynchronous RAID-1 free software that would record in a journal all the changes that I perform on the disk and replay this journal later, when I plug my external hard disk on the laptop? I guess that it would be faster than usual backup solutions (rsync, unison, you name it) that scan the whole partitions every time. Do you feel the same annoyance when backing up laptops?"
After a Chinese woman was earlier this month evidently electrocuted while talking on her iPhone while it was plugged in to charge, Apple is warning users to avoid counterfeit chargers. From CNet: "Last week, reports surfaced in China that suggested the woman, Ma Ailun, might have been using a third-party charger designed to look like the real thing. Although third-party chargers are not uncommon, they vary widely in terms of safety and quality. Earlier this year, safety consulting and certification company UL issued a warning that counterfeit Apple USB chargers were making the rounds and that consumers should be on the lookout for them due to their lower quality and possibly dangerous defects. The company posted the guidance on its site after a woman was allegedly electrocuted while answering a call on her iPhone."

Incarnate-VO writes "Many-platform space MMORPG Vendetta Online has added another first, with the official launch of support for the Oculus Rift family of head-mounted VR displays. The VR adds another level of immersion to the twitch-combat space title." A few limitations: Windows only (because the Rift only supports Windows), some effects are disabled, and the developers still want to tweak things like the HUD. But it's a good first step, and supports both the low-res and high definition revisions of the Occulus Rift.
Travis Goodspeed has authored a blog post detailing his method of tracking low-earth-orbit satellites. Starting with an old Felcom 82B dish made for use on maritime vessels, he added motors to move it around and a webcam-based homemade calibration system. "For handling the radio input and controlling the motors, I have a BeagleBone wired into a USB hub. These are all mounted on the trunk of the assembly inside of the radome, sending data back to a server indoors. ... In order to operate the dish, I wanted both a flashy GUI and concise scripting, but scripting was the higher priority. Toward that end, I constructed the software as a series of daemons that communicate through a PostgreSQL database on a server inside the house. For example, I can run SELECT * FROM sats WHERE el>0 to select the names and positions of all currently tracked satellites that are above the horizon. To begin tracking the International Space Station if it is in view, I run UPDATE target SET name='ISS';. For predicting satellite locations, I wrote a quick daemon using PyEphem that fetches satellite catalog data from CelesTrak. These positions are held in a database, with duplicates filtered out and positions constantly updated. PyEphem is sophisticated enough to predict in any number of formats, so it's easy to track many of the brighter stars as well as planets and deep-space probes, such as Voyagers 1 and 2."
New submitter rogue_archivist writes "I'm an archivist at a mid-sized university archives, trying to develop a policy for archiving computer files ('born-digital records' in archival parlance). Currently old floppy disks, CDs, and the occasional hard drive are added to our network storage. Then the physical media is separated from archival paper documents and placed into storage. My question for all you slashdotters out there is: should these disks be imaged and then the physical copies discarded? Is there any benefit for keeping around physical copies of storage media long since rendered obsolete?"
hypnosec writes "Adapteva has started shipping its $99 Parallella parallel processing single-board supercomputer to initial Kickstarter backers. Parallella is powered by Adapteva's 16-core and 64-core Epiphany multicore processors that are meant for parallel computing unlike other commercial off-the-shelf (COTS) devices like Raspberry Pi that don't support parallel computing natively. The first model to be shipped has the following specifications: a Zynq-7020 dual-core ARM A9 CPU complemented with Epiphany Multicore Accelerator (16 or 64 cores), 1GB RAM, MicroSD Card, two USB 2.0 ports, optional four expansion connectors, Ethernet, and an HDMI port." They are also releasing documentation, examples, and an SDK (brief overview, it's Free Software too). And the device runs GNU/Linux for the non-parallel parts (Ubuntu is the suggested distribution).
Nerval's Lobster writes "Last week, Microsoft announced that it would take a $900 million write-off on its Surface RT tablets. Although launched with high hopes in the fall of 2012, the sleek devices—which run Windows RT, a version of Windows 8 designed for hardware powered by the mobile-friendly ARM architecture—have suffered from middling sales and fading buzz. But if Microsoft decides to continue with Surface, there's one surefire way to restart its (metaphorical) heart: make it the ultimate bargain. The company's already halfway there, having knocked $150 off the sticker price, but that's not enough. Imagine Microsoft pricing the Surface at a mere pittance, say $50 or $75 — even in this era of cheaper tablets, the devices would fly off the shelves so fast, the sales rate would make the iPad look like the Zune. There's a historical precedent for such a maneuver. In 2011, Hewlett-Packard decided to terminate its TouchPad tablet after a few weeks of poor sales. In a bid to clear its inventory, the company dropped the TouchPad's starting price to $99, which sent people rushing into stores in a way they hadn't when the device was priced at $499. Demand for the suddenly ultra-cheap tablet reached the point that HP needed weeks to fulfill backorders. (Despite that sales spike, HP decided to kill the TouchPad; the margins on $99 obviously didn't work out to everyone's satisfaction.) In the wake of Microsoft announcing that it would take that $900 million write-down on Surface RT, reports surfaced that the company could have as many as six million units sitting around, gathering dust. Whether that figure is accurate—it seems more based on back-of-napkin calculations than anything else—it's almost certainly the case that Microsoft has a lot of unsold Surface RTs in a bunch of warehouses all around the world. Why not clear them out by knocking a couple hundred dollars off the price? It's not as if they're going anywhere, anyway."
jfruh writes "Stratasys, one of the world's biggest 3D printer manufacturers, routinely uses 3D-printed objects as displays for its booths at trade shows. The problem: It's been using objects designed by popular designer Asher Nahmias, whose creations are licensed under a noncommercial Creative Commons license — and he says Stratasys's use violates the licensing terms. This is just one example of how the nascent 3D printing industry is having to grapple with the IP implications of creating physical objects out of downloadable designs. Another important problem: IP law distinguishes between purely decorative and useful objects, but how should the digital files that provide a design for those objects be treated?" The models are copyrighted and licensed NC, but what about the resulting object? Precedent seems to imply that the resulting object cannot be controlled (e.g. the output of a GPLed program is not GPLed, so why should executing a program on a 3D printer be any different?).
