hypnosec writes "Amazon's latest Kindle Paperwhite is now officially jailbroken, giving users the ability to do things like turn their eReaders into weather station displays, or connect serially to a Raspberry Pi. To jailbreak the Paperwhite, the user needs to copy a file over to the root directory of the e-Reader and restart the device. The Kindle Paperwhite jailbreak is based on a previously known hack used on the Kindle Touch."

crookedvulture writes "SSD prices continue plummeting. In just the past quarter, street prices have fallen by double-digit percentages for most models, with some slashed by 30% or more. We've reached the point where the majority of drives cost less than a dollar per gigabyte, and that's without the special coupon codes and mail-in rebates usually attached to weekly deals. Lower-capacity drives seem more resistant to deep price cuts, making 120-256GB offerings the best values right now. It's nice to see a new class of devices go from prohibitively expensive to eminently affordable in such a relatively short amount of time."
ptorrone writes "Adafruit, the NYC based open-source hardware company led by Ladyada released their open-source Raspberry Pi WebIDE alpha today. Its goal is to be 'The easiest way to develop code on your Raspberry Pi.' To get up and running head on over to learn.adafruit.com/webide and follow the installation and setup instructions. It uses Bitbucket, and any code changes you make will be synced to your Bitbucket account. Adafruit chose Bitbucket over GitHub because they offer free secure accounts, which is very important for a Web-based IDE."
sfcrazy writes "Samsung has created a new Linux file system called F2FS. Jaegeuk Kim of Samsung writes on the Linux Kernel Mailing List: F2FS is a new file system carefully designed for the NAND flash memory-based storage devices. We chose a log structure file system approach, but we tried to adapt it to the new form of storage. Also we remedy some known issues of the very old log structured file system, such as snowball effect of wandering tree and high cleaning overhead."
another random user writes with news of a study from the Norwegian University of Science and Technology, which looked into the environmental impact of electric vehicles — not just how they do when driven, but how they are produced and by what means they are charged. The study pointed out that the production of EVs has twice as much of an environmental impact as the production of typical gas-powered cars, which must be taken into account when comparing the two. Also, they say it's important to consider the source of the electricity used to charge the vehicles. In places like Europe, where a good chunk of the electricity comes from renewable sources, EVs do indeed provide a benefit to the environment. However, "In regions where fossil fuels are the main sources of power, electric cars offer no benefits and may even cause more harm." The study says, "It is counterproductive to promote electric vehicles in regions where electricity is primarily produced from lignite, coal or even heavy oil combustion."
judgecorp writes "Each generation of smartphones actually has more dropped calls and worse battery life than the last, because antenna design has fallen behind, says Edinburgh-based Sofant Technologies. The firm has made a tunable, steerable RF antenna using micro-electro-mechanical-system (MEMS) which it says will change all that. It's based on research from Edinburgh University and is designed to get the best out of LTE/4G."
An anonymous reader writes "The CIA's investment fund, In-Q-Tel, and Amazon founder Jeff Bezos have invested $30 million in a Canadian company that claims to build quantum computers, reports Technology Review in a detailed story on why that startup, D-Wave, appears to be attracting serious interest after years of skepticism from experts. A spokesman for In-Q-Tel says that intelligence agencies 'have many complex problems that tax classical computing architecture,' a feeling apparently strong enough to justify a bet on a radically different, and largely unproven, approach to computing."
itwbennett writes "Foxconn has ambitious plans to deploy a million-robot army on its assembly lines. But while robots already perform some basic tasks, when it comes to the more delicate assembly work, humans still have the edge. George Zhang, senior principal scientist with ABB, a major vendor of industrial robots, thinks Foxconn will eventually replace human workers for much of its electronic assembly, but probably not in time for the iPhone 6. For now, humans are still a cheaper and more practical choice."
Mark Hachman writes in Slash Datacenter that the Sparc T5 chip Oracle announced earlier this year apparently won't be ready until sometime in 2013. John Fowler, executive vice president, Systems, Oracle, presented at Oracle Open World a chart outlining highlights of Oracle's plans for the future. "But Fowler also skipped over some bad news: an apparent delay for the Sparc T5. A year ago, Oracle’s Sun division announced the Sparc T4—and according to Fowler, Oracle chief Larry Ellison set a very high bar for the next iteration: double the performance while maintaining app compatibility on an annual basis. Apparently, that didn’t quite happen with the T5; Oracle had the opportunity to announce a T5-based server, and didn’t. That’s a bit of bad news for the Sun design team, which already had to watch Intel’s Xeon chief, Diane Bryant, give the preceding keynote. ... As detailed at this year’s Hot Chips conference, the T5 combines 16 CPU cores running at 3.6 GHz on a 28-nm manufacturing process. Continuing the trend of hardware acceleration of specific functions, Sun executives claimed the chip would lead in on-chip encryption acceleration, with support for asymmetric (public key) encryption, symmetric encryption, hashing up to SHA-512, plus a hardware random number generator."
New submitter SirTicksAlot writes "I attended World Makerfaire 2012 NYC this past weekend and wanted to share some of the highlights of the faire. Makerfaire is a gathering of smart and talented groups and individuals who share their love for making things. And there is nearly no limit as to what kind of ideas or projects on display. There is no age limit or restriction and kids of all ages are encouraged to interact with everything they can. If you ever go to shows and see 'DO NOT TOUCH,' you did not see that here. Touching, inspecting and learning is very much warranted. There were many stations where kids could learn to use tools, assemble things, and even learn to solder."
Lucas123 writes "The problem: What do you leave behind that billions of years from now, and without context, would give aliens an some kind of accurate depiction of mankind. The answer: A gold-plated silicon disc with just 100 photos. That's the idea behind The Last Pictures project, which is scheduled to blast off in the next few months from Kazakhstan and orbit the earth for 5 billion years. The photos, etched into the silicon using a bitmap format, were chosen over a five-year process that involved interviews with artists, philosophers, and MIT scientists, who included biologists, physicists, and astronomers. To each, was posed a single question: What photos would you choose to send into outer space? The answer became an eclectic mix of images from pre-historic cave paintings to a photo of a group of people taken by a predator drone."
Bruce Perens writes "I found myself alone in a room, in front of a deep square or rectangular pool of impressively clear, still water. There was a pile of material at the bottom of the pool, and a blue glow of Cherenkov radiation in the water around it. To this day, I can't explain how an unsupervised kid could ever have gotten in there."
An anonymous reader writes "One of the major themes of the ongoing presidential election in the United States has been the perceived need to bring product manufacturing back to the United States. A recent announcement from Lenovo is going to play to this point; the PC manufacturer said today that it's building a U.S. location in Whitsett, North Carolina. The new facility is small, with just over 100 people and is being built for a modest $2M, but Lenovo states that it's merely the beginning of a larger initiative." It makes sense: their U.S. HQ is a stone's throw away in RTP.
crookedvulture writes "Over the past few years, AMD's desktop processors have struggled to keep up with Intel's. AMD has slashed prices to make its chips more appealing, but Intel has largely held firm. Three years of historical data shows that Intel CPU prices have remained stagnant, especially for models that cost $200 and up. AMD chips, on the other hand, tend to fall in price steadily after they first hit the market. Some drop by up to 43% in the first year. This trend is a byproduct of the unhealthy competitive landscape in the desktop CPU arena, and it's been great for Intel's gross margin. Unfortunately, it's not so good for consumers."
nk497 writes "When Paul Otellini announced Ultrabooks last year, he predicted they would grab 40% of the laptop market by this year. One analyst firm has said Ultrabooks will only make up 5% of the market this year, slashing its own sales predictions from 22m this year to 10.3m. However, IHS iSuppli said that Ultrabooks have a chance at success if manufacturers get prices down between $600 to $700 — a discount of as much as $400 on the average selling price of the devices — and they could still grab a third of the laptop market by 2016."
Gunkerty Jeb writes "Researchers working on the 'physically unclonable functions found in standard PC components (PUFFIN) project' announced last week that widely used graphics processors could be the next step in online authentication. The project seeks to find uniquely identifiable characteristics of hardware in common computers, mobile devices, laptops and consumer electronics. The researchers realized that apparently identical graphics processors are actually different in subtle, unforgeable ways. A piece of software developed by the researchers is capable of discerning these fine differences. The order of magnitude of these differences is so minute, in fact, that manufacturing equipment is incapable of manipulating or replicating them. Thus, the fine-grained manufacturing differences can act as a sort of a key to reliably distinguish each of the processors from one another. The implication of this discovery is that such differences can be used as physically unclonable features to securely link the graphics cards, and by extension, the computers in which they reside and the persons using them, to specific online accounts."
FatLittleMonkey writes "You may recall Cody Wilson's project to create a 3D printed gun, mentioned previously on Slashdot. Well, the Defense Distributed project has suffered a decidedly non-technical setback, with printer manufacturer Stratasys revoking the lease and repossessing the printer (presumably prying it from plastic models of Cory's cold dead hands). According to New Scientist, the manufacturer cited his lack of a federal firearms manufacturer's license as their reason for the repossession, adding that it does not knowingly allow its printers to be used for illegal purposes." Homemade firearms are not (in the U.S.) per se illegal on a federal basis, though states have varying degrees of regulation. It would be helpful if anyone more conversant with firearms law than me can point out what law or laws this project might be breaking.
For the homebrew hardware nerds out there who also homebrew beer: "BrewPi is an open source fermentation controller that runs on an Arduino (for now) and a Raspberry Pi. It can control your beer temperature with 0.1 degree precision, log temperature data in nice graphs and is fully configurable from a web interface." Source code. The article has lots of photos and screenshots. The project involves rewiring the compressor's electrical connection through a PID controller, and includes both a fancy OLED display on the fridge and support for logging statistics and control over the web. If you've ever had the joy of gradually crash-cooling a lager (not too fast, not too slow), the software includes settings to effect gradual temperatures changes in the fermenting wort. Certainly fancier than a Johnson controller and a probe attached to a fermenter with a strip of insulating tape.
An anonymous reader writes "Looking for an inexpensive means to capture audio from a dynamically moving crowd, I sampled many MP3 players' recording capabilities. Ultimately the best bang-for-the-buck was refurbished SanDisk Sansa Clip+ devices ($26/ea) loaded with (open source) RockBox firmware. The most massively multi-track event was a thorium conference in Chicago where many attendees wore a Clip+. Volunteers worked the room with cameras, and audio capture was decoupled from video capture. It looked like this. Despite having (higher quality) ZOOM H1n and wireless mics, I've continued to use the RockBox-ified Clip+ devices ... even if the H1n is running, the Clip+ serves as backup. There's no worry about interference or staying within wireless mic range. The devices have 4GB capacity, and RockBox allows WAV capture. They'll run at least 5 hours before the battery is depleted (with lots of storage left over). I would suggest sticking with 44kHz (mono) capture, as 48kHz is unreliable. To get an idea of their sound quality, here is a 10-person dinner conversation (about thorium molten salt nuclear reactors) in a very busy restaurant. I don't know how else I could have isolated everyone's dialog for so little money. (And I would NOT recommend Clip+ with factory firmware... they only support 22kHz and levels are too high for clipping on people's collars.)" This video incorporating much of that captured audio is worth watching for its content as well as the interesting repurposing.
An anonymous reader writes with this story from Wired: "When the African Robotics Network announced their $10 robot design challenge this summer, co-founder Ken Goldberg was careful not to share too many expectations, lest he influence contestants' designs. But he never imagined one of the winning entries would prominently feature a pair of Spanish lollipops. The challenge, hosted by AFRON co-founders Goldberg and Ayorkor Korsah, emphasized inexpensive designs to help bring robotics education to African classrooms." Winners include "the lollipop-laden Suckerbot and traditional (roaming) category first prize winner Kilobot, a Harvard-spawned three-legged, vibrating, swarming robot."
