The Wiki Weapon Project and its idea of making guns with 3D printers has already been mentioned on Slashdot. It has also been written up on Forbes.com and a lot of other geek and non-geek sites. Note that when some Wiki Weapon proponents talk about making "guns" with 3D printers, they may be talking only about lower receivers or other static parts, not barrels, firing pins or other parts that must be machined to close tolerances and are subjected to a lot of stress when the gun fires. But low-cost 3D printing and low-cost CNC machining technologies are both advancing at a rapid rate, so thinking about the intersection of firearm manufacturing and open source is both worthwhile and timely. There's been a strong debate about this topic on Eric S. Raymond's Armed and Dangerous blog that's worth reading. Also recommended: The Home Gunsmith.com and CNC Gunsmithing. Astute Slashdot readers will, no doubt, recommend many more. Meanwhile, this video is about licensing, distribution, and legal matters, not the actual manufacture of firearms. There's a transcript (we're finally doing transcripts of selected videos) below the video for those who prefer to read instead of watch.

Taco Cowboy writes with news on the slipping schedules in the move toward both larger wafers and 3D integrated circuits in the semiconductor fab world. From the articles: "TSMC ... said it planned to start mass-producing next-generation 450mm wafers using advanced 10-nanometer technology in 2018. The advanced 10-nanometer chips could first be used in mobile devices and other consumer electronics, like game consoles, that demand high-performance and low power consumption. The plan was included in the latest technology roadmap unveiled by TSMC about one year after the chipmaker attributed its delay in making 450mm wafers, originally scheduled in 2015, to semiconductor equipment suppliers' postponement in developing advanced equipment for manufacturing amid the industrial slump. Chipmakers can get 2.5 times more chips from a 450mm wafer than from a 300mm wafer ... The industry's gradual migration toward 3D ICs with through-silicon vias (TSV) is unlikely to happen until 2015 or 2016, according to sources at semiconductor companies. Volume production of 3D ICs was previously estimated to take place in 2014. Leading foundries and backend assembly and test service companies have all devoted much of their R&D efforts to TSV development, and are making progress. The major players are believed to be capable of supporting 3D ICs by 2014, but the emerging technology going into commercial production may not take place until around the 2015-16 timeframe." Probably one of the most interesting presentations at HOPE9, "Indistinguishable From Magic: Manufacturing Modern Computer Chips," covered modern semiconductor fabrication and why these things are cool. If you're interested in more background (what do all of those TLAs mean?), check out the slides / audio (or attached video of the presentation from YouTube).

1sockchuck writes "Intel has just concluded a year-long test in which it immersed servers in an oil bath, and has affirmed that the technology is highly efficient and safe for servers. The chipmaker is now working on reference designs, heat sinks and boards that are optimized for immersion cooling. 'We're evaluating how (immersion cooling) can change the way data centers are designed and operated,' said Mike Patterson, senior power and thermal architect at Intel. 'I think it will catch on. It's going to be a slow progression, but it will start in high-performance computing.' Intel's test used technology from Green Revolution Cooling, which says its design eliminates the need for raised flooring, CRAC units or chillers. Other players in immersion cooling include Iceotope and Hardcore (now LiquiCool)."

dcblogs writes "Social robots — machines with the ability to do grocery shopping, fix dinner and discuss the day's news — may gain limited rights, similar to those granted to pets. Kate Darling, a research specialist at the MIT Media Lab, looks at this broad issue in a recent paper, 'Extending Legal Rights to Social Robots.' 'The Kantian philosophical argument for preventing cruelty to animals is that our actions towards non-humans reflect our morality — if we treat animals in inhumane ways, we become inhumane persons. This logically extends to the treatment of robotic companions. Granting them protection may encourage us and our children to behave in a way that we generally regard as morally correct, or at least in a way that makes our cohabitation more agreeable or efficient.' If a company can make a robot that leaves the factory with rights, the marketing potential, as Darling notes, may be significant."

redletterdave writes "Valve is reportedly interested in building hardware. The Bellevue, Wash.-based software developer added a job posting to its site on Tuesday morning for an industrial designer. We're frustrated by the lack of innovation in the computer hardware space though, so we're jumping in,' the posting said. 'Even basic input, the keyboard and mouse, haven’t really changed in any meaningful way over the years. There's a real void in the marketplace, and opportunities to create compelling user experiences are being overlooked.'"

cylonlover writes "Three-dimensional printers are popping up everywhere these days. Some are small enough to fit in a briefcase and others are large enough to print houses, but scientists at the Vienna University of Technology are going for the microscopic. Earlier this year, the university built a 3D printer that uses lasers to operate on a tiny scale. Now they're refining the technique to enable precise placement of a selected molecule in a three-dimensional material. This process, called '3D-photografting,' can potentially be used to create a 'lab on a chip' or artificially grow living tissue."

submeta writes "Researchers at MIT and the University of Pennsylvania have genetically engineered skeletal muscle cells to respond to light. The hope is that this 'bio-integrated' approach may lead to 'highly articulated, flexible robots.' The technique, known as optogenetics, has previously been used to stimulate neurons in worms to fire."

CowboyRobot writes "Is full disk encryption (FDE) worth it? A recent study conducted by the Ponemon Institute shows that the expected benefits of FDE exceed cost by a factor ranging from 4 to 20, based on a reduction in the probability that data will be compromised as the result of the loss or theft of a digital device. 'After doing all of the math, Ponemon found that the cost of FDE on laptop and desktop computers in the U.S. per year was $235, while the cost savings from reduced data breach exposure was $4,650.'"

First time accepted submitter jamiedolan writes "I've managed to consolidate most of my old data from the last decade onto drives attached to my main Windows 7 PC. Lots of files of all types from digital photos & scans to HD video files (also web site backup's mixed in which are the cause of such a high number of files). In more recent times I've organized files in a reasonable folder system and have an active / automated backup system. The problem is that I know that I have many old files that have been duplicated multiple times across my drives (many from doing quick backups of important data to an external drive that later got consolidate onto a single larger drive), chewing up space. I tried running a free de-dup program, but it ran for a week straight and was still 'processing' when I finally gave up on it. I have a fast system, i7 2.8Ghz with 16GB of ram, but currently have 4.9TB of data with a total of 4.2 million files. Manual sorting is out of the question due to the number of files and my old sloppy filing (folder) system. I do need to keep the data, nuking it is not a viable option.

coondoggie writes "Scientists at DARPA say there are some 1,300 satellites worth over $300B sitting out in Earth's geostationary orbit (GEO) that could be retrofitted or harvested for new communications roles and it designed a program called Phoenix which it says would use a squadron 'satlets' and a larger tender craft to grab out-of-commission satellites and retrofit or retrieve them for parts or reuse." This program incorporates a design challenge aspect, in which various teams compete to design systems to effect the actual capture. From the article: "In the Zero Robotics challenge, three finalist teams emerged from a series of four, one-week qualifying rounds: "y0b0tics!" (Montclair, NJ); "The Catcher in the Skye" (Sparta, NJ); and "Nitro" (Eagleville, PA). Then in June the teams gathered at the Massachusetts Institute of Technology to watch via video link as their algorithms were tested on board the ISS, DARPA said. The algorithms were applied across three situations in which the SPHERES satellite simulated an active spacecraft approaching an object tumbling through space. In each scenario, at least one of the teams was able to approach the tumbling target and remain synchronized within the predefined capture region, DARPA said."

An anonymous reader writes "AgigaTech appears to be the first company to produce a non-volatile SDRAM DIMM — an SDRAM memory module that retains its contents even without power supply. The modules combine DDR2/3 SDRAM with NAND Flash as well as a data transfer controller and an ultracapacitor-based power source to support a data transfer from the SDRAM to Flash and vice versa. If this memory makes it into production, this is something that I instantly will want and will stand in line for."

First the spec, and now the hardware: MrSeb writes "After five years of trying to convince us that 3D TVs are the future, it seems TV makers are finally ready to move on — to 4K UHDTV. At the IFA consumer electronics show in Berlin, Sony, Toshiba, and LG are all showing off 84-inch 4K (3840×2160) TVs. These aren't just vaporware, either: LG's TV is on sale now in Korea (and later this month in the US), Sony's is due later this year, and Toshiba will follow in the new year. Be warned, though: all three will cost more than $20,000 when they go on sale in the US — oh, and there's still no 4K Blu-ray spec, and no such thing as 4K broadcast TV. In other display-related news, Panasonic is showing off a humongous 145-inch 8K (7680x4320) plasma TV, and some cute 20-inch 4K displays — but unfortunately neither are likely to find their way to your living room or office in the near future."

An anonymous reader writes "I live in the Middle East. Summer temperatures occasionally reach 60C/140F, well over the operating specs for most consumer tech. Quite a number of work and residential compounds are secured, prohibiting everything from computers to cameras to phones to USB sticks to car remote controls. When I know that I'm visiting one of those compounds, I end up leaving all the tech I can at home or in the office, and only bringing a cell phone, and leaving it in my car. However, "only a cell phone" has quickly morphed into "only two cell phones, a car MP3 player and remote, and .... ooh, shiny... a new tablet... and an electric razor just in case I have to touch up before a party in a compound." I'm wondering what kind of technologies we have for keeping all this tech cool for four hours in the car. Overnight events might last longer, but won't be as hot."

MrSeb writes with news on work toward flexible batteries good enough for Real World use (you have to power those flexible electrionics somehow). From the article: "LG Chem ... has devised a cable-type lithium-ion battery that's just a few millimeters in diameter, and is flexible enough to be tied in knots, worn as a bracelet, or woven into textiles. The underlying chemistry of the cable-type battery is the same as the lithium-ion battery in your smartphone or laptop — there's an anode, a lithium cobalt oxide (LCO) cathode, an electrolyte — but instead of being laminated together in layers, they're twisted into a hollow, flexible, spring-like helix. flexible batteries have been created before — but they've all just standard, flat, laminated batteries made from sub-optimum materials, such as polymers. As such, as they have very low energy density, and they're only bendy in the same way that a thin sheet of plastic is bendy. LG Chem's cable-type batteries have the same voltage and energy density as your smartphone battery — but they're thin and highly flexible to boot. LG Chem has already powered an iPod Shuffle for 10 hours using a knotted 25cm length of cable-type battery." Original paper (Extreme Tech claims it is paywalled, but it looks like it's not). The hollow core seems to be the key: "Moreover, a nonhollow anode proved to have serious problems with penetration of the electrolyte into the essential cell components such as the separator and active materials ... However, we were able to overcome these drawbacks by devising a unique architecture comprising a skeleton frame surrounding an empty space, that is, a hollow-spiral anode with a multi-helix structure This design enables easy wetting of the battery components with the electrolyte and the hollow space allows the device to compensate for any external mechanical distortion while maintaining its structural integrity. In addition, this helical architecture possibly enables the battery to be more flexible, owing to its similarity to a spring-like structure."

andy5555 writes "I am hardcore Unix (and recently storage) fan responsible for our server department. Most of the servers run (you guessed it) different types of Unix. For quite a long time, Windows servers played very little role, but sometimes we get applications from our business departments which run only under Windows. So it seems that we have to take it seriously and hire a few Windows fans who would be able to take care of the (still small but growing) number of Windows servers. Since I am Unix fan, I have very little knowledge of Windows (some of my teammates may have more, but we are not experts). If I have to hire such a person I would like to find someone who is passionate about Windows. It is easy for me to recognize a Windows fan, but I don't know how to test his/her knowledge. There are some sites with typical Windows interview questions, but everybody can read them and prepare. How would you recommend the hiring process to proceed? What should I ask?"

MojoKid writes "Intel has selected Integrated Device Technology (IDT) to develop an integrated transmitter and receiver chipset for the company's Wireless Charging Technology (WCT) based on magnetic resonance technology, it was announced [Wednesday]. The technology won't require you to plop your smartphone or other gear on a special charging mat (based on inductive charging), but you will be able to wirelessly charge your devices from an equipped device like a notebook. In addition, magnetic resonance charging is significantly more efficient than previous generation inductive technologies and it produces less heat build up in the process. Intel didn't say when WCT will appear in shipping products, but promised to update plans and timelines at a later date."

toygeek writes "Babies, as you may have noticed if you own one, like to get into all sorts of mischief, and studies show that exploring and interacting with the world is important for cognitive development. Babies who can't move around as well may not develop at the same rate as babies who can, which is why researchers from Ithaca College in New York are working on a way to fuse babies with robots to give mobility to all babies, even those with conditions that may delay independent mobility, like Down syndrome, spina bifida, or cerebral palsy."

Nerval's Lobster writes "EMC president and incoming VMware chief executive Pat Gelsinger most likely shot down any hope that the company's storage arrays would be built around the ARM architecture. Gelsinger, who also helped orchestrate the VMworld show in San Francisco this week, presented an Aug. 29 keynote at the Hot Chips conference in Cupertino, Calif. Afterward, an audience member told Gelsinger that as many as 25 percent of all servers could be shipped around the low-power ARM architecture, then asked if Gelsinger agreed with that estimate. EMC previously shifted its product lines to Intel processors. Gelsinger told the audience member that the situation is unlikely to change, even if ARM could deliver workloads at a fraction of the power of an X86 chip."

An anonymous reader writes with this excerpt from geek.com: "Amazon has released a rather bizarre bit of news today. The Kindle Fire has completely sold out. You can no longer buy one, and the wording of the press release suggests there won't be any more manufactured. In nine months on sale Amazon claims to have secured 22 percent of tablet sales in the U.S.. With that in mind, Amazon will definitely be selling more Kindle Fires, however, the next one you'll be able to buy will probably have a '2' at the end of the name. Jeff Bezos said that the Kindle Fire is Amazon's most successful product launch so far and that there's 'an exciting roadmap ahead.' He also confirmed Amazon will continue to offer hardware, but there's no detail beyond that." Also covered on Slashcloud.

cylonlover writes "While still impressive, the capabilities of early 'tricorders,' such as the Scanadu and Dr Jansen's tricorder, fall well short of the Star Trek device that inspired them. But a new miniaturized version of a flow cytometer called the Microflow to be tested on the International Space Station (ISS) brings the age of instant diagnosis of medical conditions using a portable device a step closer. The Microflow could also make its way into doctor's offices here on Earth where it might help cut down on the number of follow up visits required after waiting to get results back from the lab."
