sandbagger writes: Printer ink is expensive, so it's important that when a printer tells you a cartridge is running dry, the cartridge is actually running dry. Unfortunately, that's not always the case. The folks over at Bellevue Fine Art in Seattle recently decided to find out exactly how much ink their high-end Epson 9900 printer wastes. A professional grade 700ml cartridge will have 120-150ml remaining when "empty," and a 350ml cartidge will have 60-80ml remaining when "empty." For this studio, the difference amounts to hundreds of dollars worth of ink every month.

MojoKid writes: Researchers from Purdue University have developed a software tool for Android smartphones that purportedly slows down battery drain when handsets enter a sleep state. With the software tool installed, the researchers claim that smartphone battery life can be extended by nearly 16 percent. Called "HUSH," the software solution was developed in response to what the researchers say is the first large-scale study of smartphone energy drain occurring from everyday use by consumers. According to their research, apps drain 28.9 percent of battery power while the screen is turned off. HUSH dynamically identifies app background activities that it deems aren't useful to the user experience on a per-app basis and suppresses those apps when the screen is turned off.

An anonymous reader writes: Earlier this year, Carnegie Mellon had one of the most capable robotics research centers in the world. Then, Uber hired away dozens of workers in a frantic push to jump start development of autonomous driving technology, which left CMU reeling. Now the NY Times asks whether such high-tech labs can continue to exist; Silicon Valley seems ready to flood such organizations with money whenever a vital new technology is almost ripe. "Carnegie Mellon's experience is a familiar one in the world of high-tech research. As a field matures, universities can wake up one day to find money flooding the premises; suddenly they're in a talent war with deep-pocketed firms from Silicon Valley. The impacts are also intellectual. When researchers leave for industry, their expertise winks off the map; they usually can't publish what they discover — or even talk about it over drinks with former colleagues. ... [Also], the intellectual register of their work changes. No more exploring hard, ''basic'' problems out of deep curiosity; they need to solve problems that will make their employers money."

Data centers have been growing in scale for years, but this project reflects the extent to which massive amounts of computing power are being concentrated in regional hubs. This super-sizing of data center campuses allows cloud platforms (and the data center providers that serve them) to rapidly add server capacity and electric power.

New submitter mutherhacker writes: A group from Osaka University in Japan and McMaster University in Canada have presented a method to control a virtual 3D object using a smartphone [video]. The method was primarily designed for presentations but also applies to virtual reality using a head mounted display, gaming or even quadrocopter control. There is an open paper online as well as a git repository for both the client and the server. The client smartphone communicates with the main computer over the network with TUIO for touch and Google protocol buffers for orientation sensor data.

This is not trivial math, and the solution of course is to use an advanced computer. If only they had one available. The best computer of the time was a targeting calculation machine that was out of service while being moved from one installation to another. The unlikely fill-in was a simple yet ingenious analog computer called the FERMIAC. When rolled along a piece of paper it calculated neutron collisions with simple markings — doing its small part to forever change the world without a battery, transistor, or tube.

The chip, developed as part of DARPA's vanishing programmable resources project, could be used to store data such as encryption keys and, on command, shatter into thousands of pieces so small, reconstruction is impossible.

Hallie Siegel writes: Ever wonder why most robots are built with hard bodies? It's because they are easier to control that way. But now researchers are embracing the complexities of soft bodies, by using their complex dynamics as an asset for solving some of the control computation, instead of using digital computation to solve it. Not surprisingly, many soft robots are inspired by nature. Researcher Helmut Hauser talks about his research in 'morphological computation', including OCTOPUS, a bio-inspired robotic silicon arm.

An anonymous reader writes: I have a decent video camera, but it lacks a terminal for using an external mic. However, I have a comparatively good audio recorder. What I'd like to do is "automagically" synchronize sound recorded on the audio recorder with video taken on the video camera, using Free / Open Source software on Linux, so I can dump in the files from each, hit "Go," and in the end I get my video, synched with the separately recorded audio, in some sane file format. This seems simple, but maybe it isn't: the 800-pound gorilla in the room is PluralEyes, which evidently lots of people pay $200 for --and which doesn't have a Linux version. Partly this is that I'm cheap, partly it's that I like open source software for being open source, and partly it's that I already use Linux as my usual desktop, and resent needing to switch OS to do what seems intuitively to be a simple task. (It seems like something VLC would do, considering its Swiss-Army-Knife approach, but after pulling down all the menus I could find, I don't think that's the case.) I don't see this feature in any of the Open Source video editing programs, so as a fallback question for anyone who's using LiVES, KDEnlive, or other free/Free option, do you have a useful workflow for synching up externally recorded sound? I'd be happy even to find a simple solution that's merely gratis rather than Free, as long as it runs on Ubuntu.

Finder.com has provided a handy resource, listing the install sizes for every PlayStation 4 game (460 and counting) and every Xbox One game (290 and counting). The list is searchable, and can be ordered.

MojoKid writes: Alienware has been relatively quiet for the past 18 months or so with respect to their X51 small form factor gaming systems. However, Intel's recent Skylake processor launch and NVIDIA's further optimizations in their Maxwell GPU architecture have given the company a fresh suite of technology to work with to enhance performance and reduce power consumption. As such, the Alienware X51 was given a complete overhaul of the lastest technologies, all of which play very well with the tighter power budgets and thermal constraints of this class of machine. Alienware calls their new machine simply the X51 R3, as it's the third revision of the product. One of the more unique design changes that Alienware made was to the graphics riser card which plugs into a X20 PCI Express slot on the motherboard. This is a rather unique approach to design efficiency which allows the Samsung NVMe M.2 gumstick Solid State Drive in this machine to ride along shotgun with the NVIDIA GeForce GTX 960, on the side of a custom riser card. Performance-wise the machine is capable of strong standard compute performance on the desktop and in the latest game titles it's able to offer up playable frame rates up through 1440p resolution with high image quality settings. Not bad for a console-sized small form factor PC, actually.

New submitter jddj writes: The Next Web reports on a hilarious design failure built into Cisco's 3650 and 3850 Series switches, which TNW terms "A Network Engineer's Worst Nightmare". By plugging in a hooded Ethernet cable, you...well, you'll just have to see the picture and laugh. They write: "The cables, which are sometimes accidentally used in datacenters, feature a protective boot that sticks out over the top to ensure the release tab isn’t accidentally pressed or broken off, rendering the cable useless. That boot would hit the reset button which happened to be positioned directly above port one of the Cisco switch, which causes the device to quietly reset to factory settings."

An anonymous reader writes: I've started a second career, teaching English at a High School in a middle class area. While the large majority of students have a computer and internet access at home, about 10-15% do not. I assign papers that must be typed, I have papers turned in online, and I plan to freely refer to texts, videos, and other resources that are available online. This gives an extra disadvantage to students that may be from the poorer end of the strata, and also means extra inefficiency for me, as I have to make allowances for students who don't have a computer available at home.

Right now, I have to tell them to either use school computers during the day, or to pick up a $170 laptop (more than enough — I administer the class using such a laptop). However, I was surprised at the lack of a super-cheap option for students. I'd love to see something for $20 that any student could afford easily, or perhaps I could just gift to a few students. I feel like something in this price range could be sufficiently powerful for basic word processing, youtube videos, and internet searches (internet access is a separate issue). But looking over my options I see:

1) The very cheapest Chromebooks are also in the $170 range.
2) Android Sticks have been around for a while, and do cost in the $20 range, but don't seem to have matured into a generally usable technology. Surprisingly, there doesn't seem to be a community effort to easily turn these Android sticks into Ubuntu/Mint sticks.
3) Students can't be assumed to have the technical know-how to fix up a Salvation Army computer (I wouldn't mind helping out a bit, but I don't want to turn into tech support)
4) A Raspberry Pi costs $70 once you include a case/power supply/etc, and students would receive a big bag of parts.
5) Cheap Windows Tablets have glitches, and don't have an HDMI out.
6) There isn't a good solution to using a cell phone as a desktop computer.

Are any of my assumptions wrong? Are there any other options I'm not considering?

An anonymous reader writes: A lengthy new article details the history of the Oculus Rift, from the VR headset's stereotypical beginnings in a hacker's parents' garage to its $2 billion acquisition by Facebook. "Luckey got into VR by way of computer games, which he was obsessed with for a time. After building what he recalls as a "beautiful six-monitor setup," for extreme visual saturation, he wondered, Why not just put a small screen directly on your face?" At just 19 years old, Luckey built a prototype good enough to impress John Carmack, which brought him all sorts of further attention. Investors came running, and eventually Mark Zuckerberg took an interest. "When Zuckerberg arrived, Luckey introduced himself and then quickly walked away. 'I'm a big fan,' he said, 'but I actually have to get back to work.' ... Zuckerberg seemed taken aback by Luckey's brusqueness but also charmed. 'They definitely have the hacker culture that we have,' he says." As the device approaches release, they're all wondering how much VR will change the world.

An anonymous reader writes: An editorial in the Wall Street Journal rings a bell we've been ringing for years: "Who owns the knowledge required to take apart and repair TVs, phones and other electronics? Manufacturers stop us by controlling repair plans and limiting access to parts. Some even employ digital software locks to keep us from making changes or repairs. This may not always be planned obsolescence, but it's certainly intentional obfuscation." The article shows that awareness of this consumer-hostile behavior (and frustration with it) is going mainstream. The author links to several DIY repair sites like iFixit, and concludes, "Repairing stuff isn't as complicated as they want you to think. Skilled gadget owners and independent repair pros deserve access to the information they need to do the best job they can."

New submitter rgreid writes: Prototypes of a new type of rover designed to explore the surface of comets and asteroids have been demonstrated recently by JPL and Stanford. Videos of the rovers in NASA's "vomit comet" show the Hedgehog prototypes performing hopping and tumbling maneuvers in a low-gravity environment. The low gravity and rough terrains found on comets and asteroids make driving with traditional rovers difficult and hazardous— the Hedgehog rovers are specifically designed to overcome these challenges and use the low gravity environment to their advantage. A last-resort "tornado" maneuver shows how the Hedgehogs could leap upwards if they get stuck in a sinkhole. The team's concept was previously covered in 2013; this recent work goes a long way toward demonstrating that Hedgehog rovers could work on a real comet or asteroid.

JMarshall writes: Recordings on old audio tapes won't be worth much in another 20 years, and some are already too degraded to play. A team including members from the Library of Congress report that infrared spectroscopy can noninvasively separate magnetic tapes that can still be played from those that can't, without risking the tapes by sticking them in a player. Unplayable tapes can sometimes be rescued by heating, which can make them playable for long enough to digitize. This method could help archivists identify which tapes need special handling before they get any worse.

An anonymous reader writes: The Raspberry Pi has been enormously successful, but one frequent request has been for the Foundation to create a simple touchscreen to go along with it. Gordon Hollingworth said, "I honestly believed it would only take us six months from start to end, but there were a number of issues we met (and other products diverted our attention from the display – like Rev 2.1, B+, A+, and Pi 2)." Now, after two years of development, they've launched a 7", 800x480 LCD that runs at 60 fps. The capacitive screen supports 10 simultaneous finger touches and has a 70 degree viewing angle. The Raspberry Pi Foundation's blog post provides some interesting technical background on electromagnetic compliance and how to connect and use the display.

Amazon has been dogged with criticism for its high-end, somewhat oddball phone, but done rather better with its high-end Fire tablets, and has mostly defined the market for e-ink book-reading devices with its long-lived Kindle series. Now, according to a report in the WSJ echoed by Fortune (and by Ars Technica and many others), the company is said to be working on a tablet aimed at the low end of the market, with a 6-inch screen, a mono speaker, and a tiny pricetag -- which could be as low as $50. "At the bottom end of the range at least, the devices won’t be priced to make a profit," writes Fortune. "The dirt-cheap price tag is intended to maximise the reach of its e-book and Amazon Prime video streaming content."

Mark Wilson writes: If you have not recently updated the firmware for your Seagate wireless NAS drives, now is the time to do so. Researchers at Tangible Security have discovered a series of vulnerabilities in a number of devices produced by Seagate that could allow unauthorized access to files and settings. An undocumented Telnet feature could be used to gain control of the device by using the username 'root' and the hardcoded default password. There are also other vulnerabilities that allow for unauthorized browsing and downloading of files, as well as permitting malicious files to be uploaded. Tangible Security says that Seagate Wireless Plus Mobile Storage, Seagate Wireless Mobile Storage, and LaCie FUEL drives are affected, but there may also be others. The security issues are confirmed to exist with firmware versions 2.2.0.005 to 2.3.0.014.
