It could be significantly improved with speech recognition for commands and text entry, a well-designed database for marginal notes and annotations, and integration with laptop and desktop computers. Google, Apple and Microsoft all have device design and manufacturing experience as well as stores that sell books and other written material. A Kindle-killing e-reader would be low-hanging fruit for Apple, Google or Microsoft — think of the competition if they each built one!" Handwriting as an input method would be nice too; a friend in college had one of the experimental Windows XP tablet PCs, and it was great for note taking and document annotation.

MojoKid writes: "NVIDIA recently announced that it would offer a free 24-hour test drive of NVIDIA GRID to anyone who wanted to see what the technology could do. It turns out to be pretty impressive. NVIDIA's GRID is a virtual GPU technology that allows for hardware acceleration in a virtual environment. It's designed to run in concert with products from Citrix, VMWare, and Microsoft, and to address some of the weaknesses of these applications. The problem with many conventional Virtual Desktop Interfaces (VDIs) is that they're often either too slow for advanced graphics work or unable to handle 3D workloads at all. Now, with GRID, NVIDIA is claiming that it can offer a vGPU passthrough solution that allows remote users to access a virtualized desktop environment built around a high-end CPU and GPU. The test systems the company is using for these 24-hour test drives all use a GRID K520. That's essentially two GK104 GPUs on a single PCB with 8GB of RAM. The TD program is still in beta, the deployment range is considerable, and the test drives themselves are configured for a 1366x768 display at 30 FPS and a maximum available bandwidth cap of 10Mbit."

A limitation of current (affordable) 3D printers is their use of open loop controllers and stepper motors which limits reliability (drove the motor too quickly and skipped a step? Your model is ruined) and precision (~300 steps per revolution). A new project, Servo Stock instead uses cheap RC Servomotors combined with Hall Effect sensors, using a closed-loop controller to precisely position the extruder. The Servo Stock is derived from the delta robot Reprap Rostock (which is pretty cool even with stepper motors). The sensors give a resolution of 4096 ticks per rotation, and the controller can currently position the motors to within +/-2 ticks. They've also simplified the printer electronics by driving as much as possible from the controlling computer using Bowler, a new communication protocol for machine control. The Servo Stock also includes sensors for the hot end, presumably to be used to control the filament feed rate and temperature. The hardware models are fully parametric, allowing reasonably straightforward scaling of the design. Source for the hardware, firmware, and software is available.

mdsolar (1045926) writes with news of nuclear plants across the U.S. dealing with the consequences of the failure of Yucca Mountain. From the article: "The steel and concrete containers used to store the waste on-site were envisioned as only a short-term solution when introduced in the 1980s. Now they are the subject of reviews by industry and government to determine how they might hold up — if needed — for decades or longer. With nowhere else to put its nuclear waste, the Millstone Power Station overlooking Long Island Sound is sealing it up in massive steel canisters on what used to be a parking lot. The storage pad, first built in 2005, was recently expanded to make room for seven times as many canisters filled with spent fuel. ... The government is pursuing a new plan for nuclear waste storage, hoping to break an impasse left by the collapse of a proposal for Nevada's Yucca Mountain. The Energy Department says it expects other states will compete for a repository ... But the plan faces hurdles including a need for new legislation that has stalled in Congress." There's always recycling or transmutation.

mdsolar (1045926) writes in with a story about how important buying the right kind of kitty litter can be. "In February, a 55-gallon drum of radioactive waste burst open inside America's only nuclear dump, in New Mexico. Now investigators believe the cause may have been a pet store purchase gone bad. 'It was the wrong kitty litter,' says James Conca, a geochemist in Richland, Wash., who has spent decades in the nuclear waste business. It turns out there's more to cat litter than you think. It can soak up urine, but it's just as good at absorbing radioactive material. 'It actually works well both in the home litter box as well as the radiochemistry laboratory,' says Conca, who is not directly involved in the current investigation. Cat litter has been used for years to dispose of nuclear waste. Dump it into a drum of sludge and it will stabilize volatile radioactive chemicals. The litter prevents it from reacting with the environment. And this is what contractors at Los Alamos National Laboratory were doing as they packed Cold War-era waste for shipment to the dump. But at some point, they decided to make a switch, from clay to organic. 'Now that might sound nice, you're trying to be green and all that, but the organic kitty litters are organic,' says Conca. Organic litter is made of plant material, which is full of chemical compounds that can react with the nuclear waste. 'They actually are just fuel, and so they're the wrong thing to add,' he says. Investigators now believe the litter and waste caused the drum to slowly heat up 'sort of like a slow burn charcoal briquette instead of an actual bomb.' After it arrived at the dump, it burst."

It wasn't long after the rise of the Oculus Rift that Sony hopped on the virtual reality bandwagon and announced a headset of their own. Now, Eurogamer has had a chance to operate and test Sony's hardware, which they say "has its own distinct vision for VR," as well as a distinct focus on console gaming. "On the 640x768 per eye first-gen Rift, the result was the perception of a disappointingly minuscule resolution, with a highly distracting "screen door" effect where you could see between the pixels. This is far less of an issue with Morpheus, and we were pleasantly surprised by how good image quality is in an environment where resolution remains at a premium. In discussing the situation with Sony, it's clear that some effort has gone into judging how to best apply the fisheye lens effect that distorts the image, with a stronger focus on retaining resolution in the key focus area. Over and above that, we wouldn't be surprised if the narrower field of view also contributes to improving image integrity. ... However, in comparing Morpheus to what we've seen from Oculus VR, it's perhaps surprising to discover that a truly transformative element of the proposition comes from a piece of hardware that you might already own: PlayStation Move. Our aspirations for the hardware were never fully realized, but the hook-up with Morpheus is a match made in heaven - in fact, if there is to be a struggle for market leadership with Oculus (and potentially Microsoft), the existing motion controller is undoubtedly one of the strongest weapons in Sony's arsenal."

Ars Technica reports that HP is back in the $100 tablet market, and this time with a tablet that's intended to be priced there instead of just a fire sale. The new offering lacks Bluetooth and GPS, among other features you might wish for in a tablet, and the screen is surrounded by a hefty bezel, but manages a pretty good list of features. Ars summarizes: "For $100, you can't expect much of the spec sheet. The HP 7 Plus has a 7-inch 1024x600 IPS display, a 1GHz quad-core Cortex A7 processor (made by a company called "Allwinner"), 1GB of RAM, 8GB of storage, 802.11 b/g/n, a microSD slot, and a 2800 mAh battery. The biggest downside HP could have fixed at this price point is the software: it's only running Android 4.2.2. Android versions are free, HP." Having an avaialble microSD slot beats some more expensive options, too.

TechCrunch's video introduction (not intended as a full review) to the recently introduced Microsoft Surface Pro 3 has mostly good things to say about the device. Reviewer Alex Wilhelm compares it to his MacBook Air, and though he's not sure that the Surface is a better fit for all-day typing than the 11" Air (slightly larger, slightly heavier than the Surface), he says the Surface does a good job of integrating input options (both finger and stylus input) that the Air -- and most laptops -- just don't have. The Washington Post's Hayley Tsukayama also compares the Surface to the Air, rather than to an Android or Apple tablet, writing, "It's heavy for a tablet, sure, but light for a laptop at 1.7 pounds. And while it doesn't have the array of ports that laptops do, you can make do with the two that it does have, a mini-display port that's good for presentations and a USB 3.0 that's good for, well, everything else. You will probably need a hub to get everything you want of this, though. (Or you could go to using Bluetooth accessories, which the Surface Pro 3 will also support.)" Ars Technica has an informative hands-on review as well, but one which parts from these by emphatically describing the Surface as a tablet, not a laptop; Ars reviewer Peter Bright gives high marks for many aspects of the design and materials, though he says his experience with the included pressure-sensitive pen was "problematic." (His initial sample pen had to be replaced, and even when it did work, it lacks tilt sensing.) Troubling for anyone who would prefer to use it as a laptop, Bright says the Surface 3 is better than its forebears but still an awkward fit for using on an actual lap, and that despite the improvements Microsoft's made it therefore isn't quite the system he's looking for.

Iddo Genuth (903542) writes "Forget about 4K displays, are Ultra Widescreen 'cinematic' displays the real deal? Earlier this year LG announced its new 34UM95 – a 34-inch Ultra Widescreen monitor with a cinematic 21:9 aspect ratio and a generous 3440 x1440 resolution — a recent hands-on review suggests that this monitor might be the new productivity king, for those who simply can't stand that annoying bezel between their multiple monitors. Linus Sebastian had a chance to play with the new LG 34UM95, and although he seems to start as a skeptic (after all, how really useful can a 21:9 display be right?) he ended up his review fully converted, with no going back. We still think that pro graphic users will not rush to switch over their EIZOs and NECs for this baby, but video editors, gamers, programmers and basically anybody who loves multitasking, might be very tempted — what do you think?"

According to The Wall Street Journal, Google may be planning to commoditze 3-D scanning by building the tech of its Project Tango project (essentially, thus far, a phone-sized handheld with 3-D sensing capabilities) into tablets. The Register speculates: "Given that Google has already announced the Project Tango smartphone, it seems likely that it would extend the technology to tablets, and the seven-inch form factor would tie in nicely with the existing Nexus 7 design. ...Google is hoping that developers can build applications to use the scanning capabilities of the Tango hardware. Suggested topics include providing guides for visually impaired people, building gaming maps based on actual rooms, and possibly augmenting Google Maps with interior details – Street View becoming Home View perhaps?" Setting aside what brand it might bear, how would you employ a portable 3-D scanner?

mrspoonsi (2955715) writes "A breakthrough has been made in SSD technology that could mean drastic performance increases due to the overcoming of one of the major issues in the memory type. Currently, data cannot be directly overwritten onto the NAND chips used in the devices. Files must be written to a clean area of the drive whilst the old area is formatted. This eventually causes fragmented data and lowers the drive's life and performance over time. However, a Japanese team at Chuo University have finally overcome the issue that is as old as the technology itself. Officially unveiled at the 2014 IEEE International Memory Workshop in Taipei, the researchers have written a brand new middleware for the drives that controls how the data is written to and stored on the device. Their new version utilizes what they call a 'logical block address scrambler' which effectively prevents data being written to a new 'page' on the device unless it is absolutely required. Instead, it is placed in a block to be erased and consolidated in the next sweep. This means significantly less behind-the-scenes file copying that results in increased performance from idle."

MojoKid (1002251) writes "The PC market is changing rapidly as tablets supplant some laptops, new players such as the Chromebook disrupt the old WIntel model, and innovations in processors and graphics allow for ever-smaller PCs such as Intel's NUC (Next Unit of Computing) PC. Gigabyte recently introduced a rather unique product that combines the tiny 4.5-inch square form factor of Intel's NUC PC platform together with a mini DLP projector. The Gigabyte Brix Projector measures 4.24 x 4.5 x 1.93 inches (WxLxD) but manages to fit in an Intel Core i3-4010U (1.7GHz) processor with built-in Intel HD 4400 graphics and support for up to 16GB of 1600MHz RAM. Finally, an mSATA slot inside the chassis also supports up to a 256GB SSD. The system's DLP (LED backlight) projector itself offers a resolution of 864x480 with an aspect ratio of 16:9 and a purported image size of 7 to 85 inches. It promises 75 ANSI lumen brightness, a contrast ratio of around 900:1, and 3LED (RGB) technology. It's not an HD setup but the potential use cases are interesting. A follow-on version capable of 1080p output would be even more useful for gaming and HD video."

cartechboy writes: "Automakers are scrambling to increase vehicle fuel economy every year as regulations increase, so when an automaker finds a way to possibly increase fuel economy by 10 percent with one new part, that gets some attention. Today that automaker is Toyota, and the part is a new semiconductor. Toyota's power control units (PCU) in its hybrids use semiconductors to govern the flow of electricity between the battery and the electric motor. Unfortunately, they're also an electrically restrictive component. Toyota says the PCU accounts for a quarter of the total electrical power losses in a hybrid drive system, and semiconductors alone make up a full fifth of the total. Reduce electrical losses through a semiconductor, and you can make your hybrid system (and therefore your car) more efficient. Toyota has done this, in theory at least, using a new silicon carbide material for its semiconductors, rather than a standard silicon unit. The future could be shaped by individual parts, and this new semiconductor tech is one piece of that puzzle."

An anonymous reader writes "Engadget reports that Samsung is working on virtual reality technology to compete with the Oculus Rift. Their work is fairly far along, and it's expected to be announced this year. It's being built to function in tandem with Samsung's flagship mobile devices, most likely their upcoming Galaxy phones and tablets. From the article: 'We're told it has an OLED screen, as good or better than in the second Rift dev kit; it's not clear how the headset connects to your phone/tablet, but we're guessing it's a wired connection rather than wireless. ...This is a device meant for use with games. What type of games? Android games! Sure, but which ones? That's certainly the question. Great games make the platform, and VR games are especially tough to crack given the newness of the medium. One thing's for sure: most major games won't work on VR as direct ports.' The report also suggests Samsung is targeting a lower price point than its competitors. True or not, it will hopefully help drive down prices for all upcoming VR tech." Meanwhile, DARPA is experimenting with the Oculus Rift for cyberwar visualization.

mdsolar writes: "[Former Australian Prime Minister Bob Hawke said] Australia bore a responsibility to assist with the safe disposal of radioactive waste, given the ample space the country possesses. 'If Australia has – as we do – the safest remote locations for storing the world's nuclear waste, we have a responsibility to make those sites available for this purpose,' he said. Hawke based this conclusion on a 25-year-old report made by Ralph Slayter, whom the former prime minister appointed as Australia's first chief scientist back in 1989. According to Slayter's report, some of the remote reaches of the Northern Territory and Western Australia could provide apt dumping grounds for radioactive waste."

When I bumped into Abram Thau at Metrix Createspace in Seattle's Capitol Hill, he showed me a few printed figurines, including a Storm Trooper (of the Star Wars variety), and I thought at first that he had printed them as duplicates of similar-sized commercial products. Not so: It turns out these are made-from-life, specifically from cos-players who have stood on Abram's human-suitable turntable (powered by a chicken rotisserie motor hooked to a 3-D printed pulley) while he scanned them in. Thau's apartment is practically shouting distance from Metrix, but that pulley was made on a large Deltabot filament printer in the corner of his living room. (A living room usefully cluttered with tools, bottles of resin, projectors in various states of repair, and more printed objects.) More interesting still, Thau's figurines are produced with a home-built resin printer. Resin is messier to work with than the filament feedstock of RepRap/Makerbot style printers (and the resin itself has a slight odor), but it allows different results. Overhanging pieces are possible without requiring elaborate support pieces built into the mesh, and the resulting product can be noticeably smoother than typical filament printing, though all 3-D printing techniques are getting better. Thau didn't buy one of the commercially available resin printers, though (like FormLabs's), but instead decided to build his own out of scavenged and off-the-shelf components. Budget concerns and improvisation rule the day (Thau is also a grad student, studying to be a middle school teacher): That means there's a book holding up the projector which is vital to curing the resin, and the printer's case is recycled from a previous one. The results look as good as the affordable commercial ones I've seen, and he's excited to teach others to make their own. Third-party resin makers and a robust market in used projectors mean that other hobbyists can follow his lead and turn their friends into figurines. (Alternate video link)

First time accepted submitter steam_cannon (1881500) writes "The U.S. Energy Information Administration (EIA.gov) is planning to release a major 96% reserve downgrade to the amount of oil and gas recoverable from the Monterey Shale formation, one of the largest oil/gas reserves in the United States. After several years of intensified exploration the Monterey oil shale play seems to have much less recoverable oil and gas then previously hoped. This is due to multiple factors such as the more complex rippled geology of the shale and over-hyped recovery estimates by investors. By official estimates the Monterey Shale formation makes up 2/3 of the shale reserves in the US and by some estimates 1/3 of all crude reserves in the US. Not a drop in the bucket. Next Month the EIA.gov will be announcing cutting it's estimates for Monterey by 96%. That's a huge blow to the US energy portfolio, trillions of dollars, oil and gas the US might have used for itself or exported. Presently the White House is evaluating making changes to US oil export restrictions so this downgrade may result in changes to US energy policy. As well as have a significant impact on US economy and the economy of California."

bauhausinteraction writes "A team from the Bauhaus-University and Native Instruments Developers built and programmed a fully functional interactive Lego Sequencer / Tangible Groove Machine that sends control data to the Maschine drum sequencer to make music. The thing was built within 24 hours as an unofficial weekend collaboration between bauhausinteraction and NI at the MidiHack 2014 in Stockholm. A standard webcam is mounted underneath the baseplate. The image is processed by a Python Script using the OpenCV Library to track the bricks. The tricky bit was to not track the user's hand, but we succeeded at that as well.

The information about brick color, position, and orientation is derived from the image and then converted into OpenSoundControl (OSC) messages. Those are sent over a network connection to a computer running Native Instruments Maschine to play back the sounds. Of course, this would work with other sound generators as well, since the whole thing simply spits out OSC-Messages and MIDI — but hey: if the guys from Native are there, you'd better use their Maschine stuff. Being real Masterbuilders, of course we used only unmodified, standard Lego Parts and no Kragle* for the construction. (*see the Lego Movie for reference.)"
