Not too many years ago, people who carried on conversations with folks the rest of us couldn't hear were considered demented (or drunk). Then came the cellular phone headset, which meant normal people could walk along, carrying on conversations with people we couldn't hear, although many researchers came to believe that a large percentage of so-called "normal" cell phone users were also demented (or drunk). Now Google's Project Glass means people can walk along, seeing things no one else can -- and carrying on conversations with them. Are Google's Project Glass users demented? Are they drunk? Or are they looking at heads-up displays mounted on glasses frames or attached to prescription glasses? Inquiring Slashdot editor Timothy Lord wanted to know, so he joined a Glass demonstration hosted by Google co-founder Sergey Brin (whose company is not related to Barney Google, as far as we know) to find out for himself -- and to share his findings with you.

Slashdot editor Jeff Boehm visted Maker Works in Ann Arbor, MI, where they not only have an Epilog Helix Laser Cutter/Engraver, but let him use it. Which, of course, he happily did, just as you or I would have done if somebody said, "Here. Borrow my laser cutter and engraving machine." The sound in the video is a little rough, since it was recorded live in a room full of loud machines -- like laser cutters. But it's still fascinating to watch (and hear) the process. The only downside is the "Ooh! I want one of those!" effect. There are used units available out there, but they cost as much as a pretty good used car. Maybe that's why there are so many Maker Spaces, also called Hacker Spaces, out there. Here's a global Hacker Space list. Hopefully, you'll find one near you, so you can do a little laser cutting (and lots of other neat stuff) yourself. Note: Slashdot accepts reader video submissions.

MrSeb writes "Applied Materials has taken the wraps off a new etching system meant to turn vertically stacked, three-dimensional transistors from lab experiments into commercial reality. The new Centura Avatar solves multiple problems facing manufacturers who are interested in 3D NAND but find their current equipment not up to the task of actually building it. According to the folks at Applied Materials, trying to build 3D NAND structures in real life would be like trying to dig a one-kilometer-deep, three-kilometer-long trench with walls exactly three meters apart, through interleaved rock strata — and that's before we discuss gate trenches or the staircases. While this machine specifically targets 3D NAND today, a number of the challenges to scaling flash memory apply to scaling CPU logic as well. As for when 3D chips will be available for commercial purchase, Applied Materials was vague on that point, but personally I would expect to see companies adopting the new etch equipment in the next few years."

lukehopewell1 writes "The Raspberry Pi is a triumph in computing, and it's now set to become a triumph in robotics as one developer plans to build a model boat around it and sail it across the Atlantic Ocean, completely unmanned. It's codenamed FishPi and will see a model boat sail across the Atlantic all by itself save for a camera, GPS module, compass and solar panels." The creator is posting updates on the build progress using a forum on his website.

theodp writes "Bill Davidow is the real Silicon Valley deal. Commenting on how Silicon Valley has changed over the decades, Davidow is not impressed, dishing out harsh words for Facebook, Apple, Google, and others. 'When corporate leaders pursue wealth in the winner-take-all Internet environment,' concludes Davidow, 'companies dance on the edge of acceptable behavior. If they don't take it to the limit, a competitor will. That competitor will become the dominant supplier — one monopoly will replace another. And when you engage in these activities you get a different set of Valley values: the values of customer exploitation.'"

An anonymous reader writes with an update on DARPA's plans to rebuild satellites in orbit. "A year old DARPA program which aims to recycle satellites in orbit has started its next phase by looking for a guinea pig defunct satellite to use for evaluating the technology required. The program involves a Dr Frankensat 'complete with mechanical arms and other "unique tools"' and blank "satlets" to build upon.' Need parts! Kill the little one!" If we're ever going to build space craft and other things in orbit, this seems like a great first step.

wasimkadak writes "This robot hand will play a game of rock, paper, scissors with you. Sounds like fun, right? Not so much, because this particular robot wins every. Single. Time. It only takes a single millisecond for the robot to recognize what shape your hand is in, and just a few more for it to make the shape that beats you, but it all happens so fast that it's more or less impossible to tell that the robot is waiting until you commit yourself before it makes its move, allowing it to win 100% of the time."

An anonymous reader writes "Eugene Goostman, a chatbot imbued with the personality of a 13-year-old boy, won the biggest Turing test ever staged on 23 June, the 100th anniversary of the birth of Alan Turing. Held at Bletchley Park near Milton Keynes, UK, where Turing cracked the Nazi Enigma code during World War 2, the test involved over 150 separate conversations, 30 judges, 25 hidden humans and five elite, chattering software programs. 'Thirteen years old is not too old to know everything and not too young to know nothing,' explains Eugene's creator, Vladimir Veselov."

raque writes "Following up on an earlier story, a group of aviation archaeologists will use underwater robots along with submersibles and sonar to search for Amelia Earhart's plane. The International Group for Historic Aircraft Recovery will search this July for the aircraft, which went down 75 years ago. 'If there's wreckage there that can be recovered, we need to know what it is, how big it is, what it looks like, and what it's made of so we can prepare a recovery expedition that has equipment to raise whatever's there,' said Richard Gillespie, the group's executive director."

crookedvulture writes "The new iPad has received a lot of attention for its high-density display, but it's not the only tablet with extra pixels. Enter Asus' Transformer Prime Infinity, which has a 10.1" screen with a 1920x1200 resolution. The display doesn't look as good as the iPad's Retina panel, which has crisper text and better color reproduction. However, the Android-based Transformer has perks the iPad lacks, like an ultra-bright backlight, a Micro HDMI port, a microSD slot, and more internal storage. The Infinity is also compatible with an optional keyboard dock that adds six hours of battery life, a touchpad, a full-sized SD slot, and a standard USB port. The Transformer's tablet component is definitely no iPad-killer. When combined with the dock, though, the resulting hybrid offers a much more flexible computing platform."

jdray writes "My wife and I own a mid-sized restaurant with a couple of Point of Sale (POS) terminals. The software, which runs on Windows and .NET, uses SQL Server on the back end. With an upgrade to the next major release of the software imminent, I'm considering upgrading the infrastructure it runs on to better ensure uptime (we're open seven days a week). We can't afford several thousand dollars' worth of server infrastructure (two cluster nodes and some shared storage, or some such), so I thought I'd ask Slashdot for some suggestions on enabling maximum uptime. I considered a single server node running VMWare with a limp-mode failover to a VMWare instance on a desktop, but I'm not sure how to set up a monitoring infrastructure to automate that, and manual failover isn't much of an option with non-tech staff. What suggestions do you have?"

An anonymous reader writes "Sandia Research Laboratory believes it has come up with a much more efficient solution than heatsink-fan cooling a CPU that simply combines the heatsink and fan components into a single unit. What you effectively get is a spinning heatsink. The new design is called the Sandia Cooler. It spins at just 2,000 RPM and sits a thousandth of an inch above the processor. Sandia claim this setup is extremely efficient at drawing heat away from the chip, in the order of 30x more efficient than your typical heatsink-fan setup. The Sandia Cooler works by using a hydrodynamic air bearing. What that means is when it spins up the cooler actually becomes self supporting and floats above the chip (hence the thousandth of an inch clearance). Cool air is drawn down the center of the cooler and then ejected at the edges of the fins taking the heat with it. And as the whole unit spins, you aren't going to get dust build up (ever)."

MrSeb writes "American and Israeli researchers have used twisted, vortex beams to transmit data at 2.5 terabits per second. As far as I can discern, this is the fastest wireless network ever created — by some margin. These twisted signals use orbital angular momentum (OAM) to cram much more data into a single stream, without using more spectrum. In current state-of-the-art transmission protocols (WiFi, LTE, COFDM), we only modulate the spin angular momentum (SAM) of radio waves, not the OAM. If you picture the Earth, SAM is our planet spinning on its axis, while OAM is our movement around the Sun. Basically, the breakthrough here is that researchers have created a wireless network protocol that uses both OAM and SAM. In this case, Alan Willner and fellow researchers from the University of Southern California, NASA's Jet Propulsion Laboratory, and Tel Aviv University, twisted together eight ~300Gbps visible light data streams using OAM. For the networking nerds, Willner's OAM link has a spectral efficiency of 95.7 bits per hertz; LTE maxes out at 16.32 bits/Hz; 802.11n is 2.4 bits/Hz. Digital TV (DVB-T) is just 0.55 bits/Hz. In short, this might just be exactly what our congested wireless spectrum needs."

Freshly Exhumed writes "Danny Sullivan over at Marketing Land has been tipped over the edge by various colleagues: 'After seeing yet another "hands-on" review of the Microsoft Surface tablet, I thought it would be interesting to shed more light on what exactly the journalists who assembled in Hollywood this week for the Surface launch event actually got to do with the tablets. In short, not a lot. Come along as I explain the hands-off reality of what I saw.' In response to Sullivan's criticisms, TechRadar contributor Mary To Many rebuts that merely touching something that does not operate nor even truly exist equates to an actual hands-on review. So, what do Slashdotters expect a "hands-on" review to reveal and/or include?"

sfcrazy writes "It seems that recent comments made by Linus Torvalds have made the people at NVIDIA take Linux more seriously. Recently Nvidia employee Stephen Warren asked in the Kernel Summit mailing list what could be done differently to make Linux support better. 'In a Google+ comment, Linus noted that we have mainly been contributing patches for Tegra SoC infra-structure details. I'm curious what other areas people might expect me/NVIDIA to contribute to. I assume the issue is mainly the lack of open support for the graphics-related parts of our HW, but perhaps there's some expectation that we'd also start helping out some core area of the kernel too? Would that kind of thing help our image even if we didn't open up our HW?'"

An anonymous reader writes "The Ivy Bridge graphics processor from Intel is now fully documented under the Creative Commons. Intel released four volumes of documents (2400+ pages) covering their latest graphics core as a complete programming guide with register specifications. Included with the graphics documentation is their new execution unit and video engine."

An anonymous reader writes "The benchmarks are in for the Radeon HD 7970 GHz Edition. Starting at $500, AMD's new single-GPU flagship boosts the original 7970's clock speed from 925 MHz to 1 GHz (1050 MHz with Boost). The GHz Edition also sports 3 GB of faster 1500 MHz GDDR5 memory, pushing 288 GB/s as opposed to 264 GB/s. While the AMD reference board runs hot and loud, retail boards will use different cooling solutions. A simple test of aftermarket GPU coolers shows that any other option will shave degrees and slash decibels. But it's the Catalyst 12.7 beta driver that really steals the show for AMD, pushing FPS scores into overdrive. With the new Catalyst, Nvidia's GeForce GTX 670 can no longer beat the original Radeon HD 7970, and the GHz Edition outmaneuvers the GeForce GTX 680 in most cases. However, when factoring price and possible overclocking into the equation, the original Radeon HD 7970 and GeForce GTX 670 remain the high-end graphics cards to beat."

CIStud writes "Anyone who goes to see Pixar's new animated Brave film might come home with their ears ringing. Why? because Brave is the debut of Dolby Lab's new 62.2 surround sound format called Atmos, which adds new developments such as pan-through array and overhead speakers. With 62 speakers and 2 subwoofers, only a handful of theaters nationwide will be able to show the film at its full throttle. Dolby has produced a new highly informative video that talks about how movie sound has progressed from mono to stereo to LCR (left/center/right) to 5.1 and 7.1 surround sound and now Atmos. The big question is will the 62.2 format system be adapted for home theaters intent on emulating the immersive movie experience?" I've seen some busy input/output panels on home stereo equipment, but 62 channels is too many for my interconnect budget. Still, overhead sound seems like a good idea for some kinds of movie.

Nerval's Lobster writes "A day after Microsoft unveiled Windows Phone 8, a company executive explained why the company never implemented native code in Windows Phone 7, declined to say whether Windows Phone 7.x would be upgraded beyond version 7.8, and said Microsoft has no plans to acquire an OEM to manufacture smartphones in-house. Of course, in theory that wouldn't stop Microsoft from building its own hardware in-house, similar to what Google did with the Nexus One. In any case, Microsoft's decision to construct its hardware and software in-house for the Surface tablet project has led to some chatter that it could do the same for smartphones."

crookedvulture writes "Hard drive prices have yet to return to normal after last year's Thailand flooding. There's good news on the solid-state front, though. The current generation of SSDs has steadily become much cheaper over the last year or so. SSD prices have dropped an average of 46% since early 2011. Intel has largely shied away from discounting its drives, but the aggressive competition between other players in the market seems to have forced its hand. There's no indication that competition is waning, suggesting the downward trend will continue. Right now, an impressive number of drives are available for less than a dollar per gigabyte."
