Ask Slashdot: What Inspired You To Start Hacking? 153

An anonymous reader writes "What got you into hacking? This is a question that Jennifer Steffen, IOActive CEO, often asks hackers she meets on conferences around the world. More often than not, the answer is movies: War Games, Hackers, The Matrix, and so on. But today, it is the real life hacking that is inspiring the movies of tomorrow. 'Hackers are doing epic stuff,' she says, and they are now inspiring movies and comics. So, what got you started? And what makes a good hacker today?"

Video A Bike Taillight that Goes Beyond Mere Taillighting (Video) 86

Meet David. Tim Lord ran into him at the 2014 Maker Faire Bay Area. He didn't have a display, and he wasn't obviously trying to sell anything or promote a Kickstarter campaign. He was just walking around with a panel full of LEDs that he wears as a backpack while riding his bike, which beats the heck out of regular bike taillights, even the blinky flashy ones a lot of us have these days. So good on you, David. This is your three minutes of Slashdot fame -- and please note, people, that you can now fast-forward through any preroll ads longer than 30 seconds, so you won't get bombed with multi-minute ads to watch a three minute Slashdot video.

How LEDs Are Made 93

An anonymous reader writes "The SparkFun team took a tour of a factory in China that manufactures LEDs. They took lots of pictures showing the parts that go into the LEDs, the machines used to build them, and the people operating the machines. There's a surprising amount of manual labor involved with making LEDs. Quoting: 'As shipped on the paper sheets, the LED dies are too close together to manipulate. There is a mechanical machine ... that spreads the dies out and sticks them to a film of weak adhesive. This film is suspended above the lead frames ... Using a microscope, the worker manually aligns the die, and, with a pair of tweezers, pokes the die down into the lead frame. The adhesive in the lead frame wins (is more sticky), and the worker quickly moves to the next die. We were told they can align over 80 per minute or about 40,000 per day.'"

Tiniest Linux COM Yet? 76

DeviceGuru writes: "An open-spec COM that runs OpenWRT Linux on a MIPS-based Ralink RT5350 SoC has won its Indiegogo funding. The $20, IoT-focused VoCore measures 25 x 25mm. How low can you go? Tiny computer-on-modules (COMs) for Internet of Things (IoT) applications are popping up everywhere, with recent, Linux-ready entries including Intel's Atom or Quark-based Edison, Ingenic's MIPS/Xburst-based Newton, Acme Systems's ARM9/SAM9G25 based Arrietta G25, and SolidRun's quad-core i.MX6-based MicroSOM. Now, an unnamed Chinese startup has raised over six times its $6,000 Indiegogo funding goal for what could be the smallest, cheapest Linux COM yet."

Ford's Bringing Adaptive Steering To the Masses 128

cartechboy writes: "Most automakers have made the jump from hydraulic power steering to electronic power steering to help conserve fuel. By using an electric motor instead of a hydraulic system, less energy is drawn from the engine. Many luxury automakers have also introduced adaptive steering with the electronic power steering systems, but now Ford is looking to bring this feature to the masses. Adaptive steering builds on the existing speed-sensitive function of the electronic power steering system by altering the steering ratio and effort based on driver inputs and settings. The system uses a precision-controlled actuator placed inside the steering wheel. It's an electric motor and gearing system that can essentially add or subtract from the driver's steering inputs. This will make the vehicle easier to maneuver at low speeds, and make a vehicle feel more stable at high speeds. The system (video) will be offered on certain Ford vehicles within the next 12 months."

4K Displays Ready For Prime Time 207

An anonymous reader writes "After the HD revolution, display manufacturers rolled out gimmick after gimmick to try to recapture that burst of purchasing (3-D, curved displays, 'Smart' features, form factor tweaks, etc). Now, we're finally seeing an improvement that might actually be useful: 4K displays are starting to drop into a reasonable price range. Tech Report reviews a 28" model from Asus that runs $650. They say, 'Unlike almost every other 4K display on the market, the PB287Q is capable of treating that grid as a single, coherent surface. ... Running games at 4K requires tons of GPU horsepower, yet dual-tile displays don't support simple scaling. As a result, you can't drop back to obvious subset resolutions like 2560x1440 or 1920x1080 in order to keep frame rendering times low. ... And single-tile 4K at 30Hz stinks worse, especially for gaming. The PB287Q solves almost all of those problems.' They add that the monitor's firmware is not great, and while most options you want are available, they often require digging through menus to set up. The review ends up recommending the monitor, but notes that, more importantly, its capabilities signify 'the promise of better things coming soon.'"

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."
