Scott Adams's Plan For Building Giant Energy-Generating Pyramids 107

LoLobey (1932986) writes "Scott Adams has proposed a pyramid project to save the world via energy generation and tourism. Basically build giant pyramids, miles wide and high, in the desert to generate power via chimney effect and photo voltaics with added features for tourism (he's planning ahead for when robots take over all the work and we'll need something to do). He's had a few "Big Ideas" lately (canals, ice bergs, ion energy)."

Curved TVs Nothing But a Gimmick 261

Lucas123 (935744) writes "Currently, the hottest trend from TV manufacturers is to offer curved panels, but analysts say it's nothing more than a ploy to pander to consumers who want the latest, coolest-looking tech in their home. In the end, the TVs don't offer better picture quality. In fact, they offer a degraded view to anyone sitting off center. Samsung and LG claim that the curve provides a cinema-like experience by offering a more balanced and uniform view so that the edges of the set don't appear further away than the middle. Paul Gray, director of European TV Research for DisplaySearch, said those claims are nothing by pseudo-science. "Curved screens are a gimmick, much along the same lines as 3D TVs are," said Paul O'Donovan, Gartner's principal analyst for consumer electronics research."

The Energy Saved By Ditching DVDs Could Power 200,000 Homes 339

Daniel_Stuckey (2647775) writes "The environmental benefits of streaming a movie (or downloading it) rather than purchasing a DVD are staggering, according to a new U.S. government study by researchers at the Lawrence Berkeley National Laboratory. If all DVDs purchased in 2011 were streamed instead, the energy savings would have been enough to meet the electricity demands of roughly 200,000 households. It would have cut roughly 2 billion kilograms of carbon emissions. According to the study, published in Environmental Research Letters, even when you take into account cloud storage, data servers, the streaming device, streaming uses much less energy than purchasing a DVD. If, like me, you're thinking, 'who buys DVDs anymore, anyways?', the answer is 'a lot of people.'" The linked paper is all there, too — not just an abstract and a paywall.

Valve's Steam Machines Delayed, Won't Be Coming In 2014 134

sfcrazy (1542989) writes "Valve has announced that its Steam Machines won't be available in the market anytime in 2014. The company delayed the release due to ongoing work on the Steam Controller. Valve's Eric Hope explains on Steam Forums why the work on controller is causing the delay: 'We're now using wireless prototype controllers to conduct live playtests, with everyone from industry professionals to die-hard gamers to casual gamers. It's generating a ton of useful feedback, and it means we'll be able to make the controller a lot better. Of course, it's also keeping us pretty busy making all those improvements. Realistically, we're now looking at a release window of 2015, not 2014.'"

Robots Will Pave the Way To Mars 95

szotz (2505808) writes "There's a lot of skepticism swirling around NASA's plan to send humans to Mars in the 2030's, not to mention all those private missions. If we want to have sustainable (read: not bank-breaking) space exploration, the argument goes, there's no way we can do it the way we've been going to the moon and low-Earth orbit. We have to find a way to exploit space resources and cut down on the amount of stuff we need to launch from Earth. That's not a new idea. But this article in IEEE Spectrum suggests research on resource extraction and fabrication in low and zero gravity might actually be making progress...and that we could take these technologies quite far if we get our act together."

Video Bunnie Huang Shows Off His Open Source Laptop (Video) 24

Bunnie Huang is both a hardware and software hacker, but that's greatly understating the case: renaissance man is more like it. Bunnie doesn't just tinker with one-off system modifications or console mods (though he's done that, too) -- he creates and repurposes at scale. (He's also an author, respected researcher with interesting thoughts on a wide range of topics, like how to think of the H1N1 flu from the point of view of a security researcher.) Bunnie's latest long-term project has been mentioned a few times on Slashdot: It's an open-source laptop computer that goes much farther than some other open-source hardware projects, and as a bonus includes an FPGA as well as a conventional -- but unusual -- processor. (Bunnie grants that there are still bits that aren't quite open source, but points out that we also don't have the software that runs the fabs; there's a point of diminishing returns.) A crowd funding campaign (via CrowdSupply) was successful enough to also fund several stretch goals, including a general purpose breakout board. I talked with Bunnie at the recent Bay Area Maker Faire. (Expect more from that show in coming weeks.) He walked us through the state of the hardware, and talked about some of the design decisions that go into making a computer that is of, by, and for hackers. (Alternate video link)

I Want a Kindle Killer 321

lpress (707742) writes "Amazon's Kindle is a good e-reader and they've sold around 40 million units, but it is far from perfect. 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.

Test-Driving NVIDIA's GRID GPU Cloud Computing Platform 29

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."

Servo Stock 3D Printer Brings Closed-Loop Control To Reprap 56

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.

US Nuclear Plants Expanding Long-Term Waste Storage Facilities 187

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.

Organic Cat Litter May Have Caused Nuclear Waste Accident 174

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."

Hands-On With Sony's VR Headset 46

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."

HP Delivers a Big-Name, 7-inch Android Tablet For $100: Comes With Compromises 182

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 and Others On the Microsoft Surface Pro 3 136

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.

Is LG's New Ultra Widescreen Display Better Than "Normal" 4K? 304

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?"

Google Rumored To Be Making 3D-Scanning Tablets 55

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?

New Middleware Promises Dramatically Higher Speeds, Lower Power Draw For SSDs 68

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."

Gigabyte Brix Projector Combines Mini PC With DLP Projector In a 4.5-Inch Cube 44

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."

New Semiconductor Could Improve Vehicle Fuel Economy By 10 Percent 119

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."
