Many of these supercomputers are striking not just for their processing power, but for their design and appearance as well. Here's a visual guide to the top finishers in the latest Top 500 list, which was released this week at the SC11 conference."

The mixed reviews so far available for the new Amazon Fire tablet mostly address the Fire in its intended role as a locked-down portal through which to buy and consume ready-made content from Amazon. New submitter terracode writes with a different kind of review, which "goes into depth on the Kindle Fire's hardware, and provides details on how to root and tweak the tablet." The article also provides a friendly chart comparing the hardware in the Fire to that of the Nook Color and the iPad 2.

"The MacBook Air and the Ultrabook come without a piece of hardware that's been a mainstay in laptops for a long time — the optical drive," says a piece at CNET. "Maybe because they really aren't that necessary anymore." I would have thought otherwise a few years ago, but traveling in the meantime with a small netbook was certainly handy. Since that machine died, I think I've used the optical drive in its low-end laptop successor a grand total of once, which was to test its wireless compatibility with a Live CD Linux distro.

RedEaredSlider passes along this excerpt about what looks like a smart advance in controlling hobbyist robots:"The concept is quite simple: put a wheeled chassis on a smart phone or iPod Touch that allows for using the device as the 'brain.' But that simplicity is what makes the robot, called Romo, powerful. Since the controls are contained entirely within the phone, they can be downloaded as apps. One can add new physical capabilities to Romo -– a claw, or a scoop -– but that doesn't require any new additions to the phone. Also, the controls are through the headphone jack. That simplifies the design and means that the robot doesn't need to be linked with only one brand of smart phone."

MrSeb writes "Did you know that Newegg is the second largest e-tailer in the U.S., after Amazon? Perhaps building your own computer isn't dead yet! Matthew Murray was recently invited to take a tour of the Newegg east coast distribution center and see what goes on behind the scenes. 'The 350,000-square-foot Edison warehouse not only houses some 15,000 SKUs of products, it also ships as many as 15,000 packages a day ... All of the different products the company carries are sorted both by category and how easy they are to move: Obviously, HDTVs are more cumbersome and difficult to remove safely than processors. Some mobile equipment, such as laptops, netbooks, and tablets, are stored in a special “high-value” area behind a chain-link fence that’s been erected within the warehouse itself.'"

absolut.evil writes "FXI Technologies has taken a dual core smartphone-esque computer and put it into a little USB stick. Neat. This allows you to plug into anything with a screen, USB port, and input device and run your own instance of Android. It weighs 21 grams and contains 'a dual-core 1.2-GHz Samsung Exynos ARM CPU (same as in the Galaxy S II), 802.11n Wi-Fi, Bluetooth, HDMI-out and a microSD card slot for memory.'"

hweimer writes "A new study by a French government agency, commissioned in the wake of the Fukushima disaster, found that all French nuclear power plants do not offer adequate safety when it comes to flooding, earthquakes, power outages, failure of the cooling systems and operational management of accidents. While there is no need for immediate shutdown, the agency presses for the problems to be fixed quickly. France gets about 80% of its power from nuclear energy and is a major exporter of nuclear technology."

An anonymous reader writes "Canadian robotic design house eatArt has released a video of its latest project: the Titanoboa, a robotic snake based on a 50-foot long prehistoric serpent. The video pits the basilisk-like robot against the Mondo Spider, a walking machine large enough to hold a man, and there's obvious competition between the two. While eatArt showed a shorter version of the snake rollerblading at the Burning Man festival earlier this year, at 35 feet this is the largest version of the robot so far, with the team aiming to reach the full length in the next year or so."

jfruhlinger writes "The infrastructure of a large data center poses two main problems: You need to find a way to reliably power all those servers, and you need to figure out a way to deal with the heat those servers put off. Syracuse University and the University of Toledo are experimenting with one gadget to solve both problems. Small power units that run on natural gas, called microturbines, provide reliable DC power separate from the utility grid, and their heat output can paradoxically be harnessed to cool the servers and transmit the heat to other buildings on campus."

New submitter PerlJedi writes "There is a very cool write up on the Make blog about an effort to build the world's largest tesla coils. Quoting: '"Somehow lightning can generate huge discharges with only about a fifth of the voltage per foot that lab discharges require," Leyh explains. "The part that especially fascinates me is that this mysterious ability kicks in around 200' in length, which is right at the edge of what we can produce with a practical machine." Leyh wants to see if humans can replicate this voltage economy effect, and has launched a Kickstarter campaign to fund the building of two 10-story Tesla Coil towers (obviously superseding his current coil-size world record).'"

MrSeb writes "'Last week, Intel announced that it had added x86 optimizations to Android 4.0, Ice Cream Sandwich, but the text of the announcement and included quotes were vague and a bit contradictory given the open nature of Android development. After discussing the topic with Intel we've compiled a laundry list of the company's work in Gingerbread and ICS thus far, and offered a few of our own thoughts on what to expect in 2012 as far as x86-powered smartphones and tablets are concerned.' The main points: Intel isn't just a chip maker (it has oodles of software experience); Android's Native Development Kit now includes support for x86 and MMX/SSE instruction sets and can be used to compile dual x86/ARM, 'fat' binaries; and development tools like Vtune and Intel Graphics Performance Analyzer are on their way to Android."

UnknowingFool writes "In a vote of 9-3, a jury found that Micron and Hynix did not collude to manipulate DRAM prices in a violation of California anti-trust law against Rambus. The jury also ruled that the Idaho based Micron and the South Korea based Hynix did not interfere with Rambus' relationship with Intel. On the first point, Rambus argued the two chip makers conspired to keep Rambus RDRAM prices high while artificially keeping their SDRAM prices low. Micron and Hynix countered that high RDRAM prices were due to technical problems of the design. On the second point, an Intel manager testified that Rambus contract stipulations soured the relationship. The clause that Rambus insisted and would not waive was that to use Rambus RDRAM, Intel had to agree to give Rambus the ability to block Intel processors if Rambus felt Intel was not promoting RDRAM sufficiently. Rambus initiated the suit and the $4B was how much Rambus calculated it lost in profits."

An anonymous reader writes "French researchers have demonstrated a robot that controls its own arm as well as a person's arm to manipulate objects in a collaborative manner, IEEE reports. Electrodes attached to the person's arm allow the robot to make the elbow and hand move to perform tasks. The tasks are currently simple (dropping a ball through a hoop, as shown in one of their videos), but the researchers say more complex ones are possible. They also say the approach has therapeutic benefits and their goal is to 'develop robotic technologies that can help people suffering from paralysis and other disabilities to regain some of their motor skills.'"

daem0n1x writes "Could this be the breakthrough we've all been expecting that will finally make the electric car a reality? Researchers of Northwestern University USA discovered a new way to build lithium-ion batteries that changes dramatically both the charge time and capacity [original paper, paywalled]. Guess what it involves? That's right, graphene."

MrSeb writes with this excerpt from an Extreme Tech article: "With 400 transistors and standard CMOS manufacturing techniques, a group of MIT researchers have created the first computer chip that mimics the analog, ion-based communication in a synapse between two neurons. Scientists and engineers have tried to fashion brain-like neural networks before, but transistor-transistor logic is fundamentally digital — and the brain is completely analog. Neurons do not suddenly flip from '0' to '1' — they can occupy an almost-infinite scale of analog, in-between values. You can approximate the analog function of synapses by using fuzzy logic (and by ladling on more processors), but that approach only goes so far. MIT's chip is dedicated to modeling every biological caveat in a single synapse. 'We now have a way to capture each and every ionic process that's going on in a neuron,' says Chi-Sang Poon, an MIT researcher who worked on the project. The next step? Scaling up the number of synapses and building specific parts of the brain, such as our visual processing or motor control systems. The long-term goal would be to provide bionic components that augment or replace parts of the human physiology, perhaps in blind or crippled people — and, of course, artificial intelligence. With current state-of-the-art technology it takes hours or days to simulate a simple brain circuit. With MIT's brain chip, the simulation is faster than the biological system itself."

holy_calamity writes "Technology Review has an update on a screen technology from Qualcomm called Mirasol that delivers LCD-like colors and video but sips power like e-ink. Demonstration Android tablets with 5.7 inch Mirasol displays apparently held up well in bright light and were responsive enough for gaming. Qualcomm are in the process of building a $1 billion new factory to make the screens, which should appear in devices from phone and tablet makers next year."

An anonymous reader writes "Yesterday, the final Raspberry Pi printed circuit board (PCB) layout was revealed. The word 'packed' comes to mind as this is one very complicated looking board. The reason for that is just how much Raspberry Pi has strived to save money on the machine by using complex routing to keep things small and cheap. The Raspberry Pi team don't believe the design is going to change again unless they missed something. With that in mind, they revealed the final board is exactly the same size as a credit card, measuring 85.65 x 53.98mm."

Zothecula writes "Russian aircraft company MiG is best known for its fighter planes which have been used by the USSR, China, North Korea and North Vietnam since the beginning of WWII. These days, the former Government-owned RAC MiG is a publicly traded entity and competes on the open market with its technologies, having more than 1600 of its MiG-29 fighters in operation in 25 countries. Now MiG is claiming a major first in military aviation with the launch of a 3D flight simulator at the Dubai Air Show, providing volumetric visualization of beyond-the-cockpit space for trainee top guns. The simulator comes complete with the MiG-29's cockpit and actual control systems."

harrymcc writes "On November 15th 1971, Intel introduced the 4004 — the first single-chip microprocessor. Its offspring, needless to say, went on to change the world. But first, Intel tried using the 4004 in a bunch of products that were interesting but often unsuccessful — like a pinball machine, an electronic vote-counting machine, and Wang's first word processor. Technologizer's Benj Edwards is celebrating the anniversary with an illustrated look back at this landmark chip." Here's another nostalgic look back at V3.co.uk, and one at The Inquirer. And an anonymous reader points out another at ExtremeTech, from which comes this snippet: "Designed by the fantastically-forenamed Federico Faggin, Ted Hoff, and Stanley Mazor, the 4004 was a 4-bit, 16-pin microprocessor that operated at a mighty 740KHz — and at roughly eight clock cycles per instruction cycle (fetch, decode, execute), that means the chip was capable of executing up to 92,600 instructions per second. We can’t find the original list price, but one source indicates that it cost around $5 to manufacture, or $26 in today’s money."

RulerOf writes "A few years ago, my girlfriend's grandfather was diagnosed with Macular Degeneration. Ever since, he has had progressively more trouble with daily activities. While his wife and family are able to help him with most things, at the age of 88 and without many living friends left, he dearly misses the ability to read printed text. He was able to get by for some time with magnifying glasses and other basic aids but now even those do not help. Recently, a local clinic which specializes in treatment for low-sight and blind individuals made him aware of and showed him several assistive reading devices that successfully allowed him to read. He mentioned this to his family members, and when I was told about it, I thought that these devices sounded like they were not much more than a camera attached to an LCD monitor or television with a little bit of special software thrown into the mix."
