Princeton Nuclear Fusion Reactor Will Run Again 147

Posted by samzenpus
from the back-to-life dept.
mdsolar writes with good news for the National Spherical Torus Experiment. Tucked away from major roadways and nestled amid more than 80 acres of forest sits a massive warehouse-like building where inside, a device that can produce temperatures hotter than the sun has sat cold and quiet for more than two years. But the wait is almost over for the nuclear fusion reactor to get back up and running at the Princeton Plasma Physics Laboratory. "We're very excited and we're all anxious to turn that machine back on," said Adam Cohen, deputy director for operations at PPPL. The National Spherical Torus Experiment (NSTX) has been shut down since 2012 as it underwent a $94 million upgrade that will make it what officials say will be the most powerful fusion facility of its kind in the world. It is expected to be ready for operations in late winter or early spring, Cohen said.

Dropbox Caught Between Warring Giants Amazon and Google 272

An anonymous reader writes: Google and Amazon are both aggressively pursuing the cloud storage market, constantly increasing available storage space and constantly dropping prices. On its face, this looks great for the consumer — competition is a wonderful thing. Unfortunately, many smaller companies like Box, Dropbox, and Hightail simply aren't able to run their services at a loss like the giants can. Dropbox's Aaron Levie said, "These guys will drive prices to zero. You do not want to wait for Google or Amazon to keep cutting prices on you. 'Free' is not a business model."

The result is that the smaller companies are pivoting to win market share, relying on specific submarkets or stronger feature sets rather than available space or price. "Box is trying to cater to special data storage needs, like digital versions of X-rays for health care companies and other tasks specific to different kinds of customers. Hightail is trying to do something similar for customers like law firms. And Dropbox? It is trying to make sure that its consumer-minded service stays easier to use than what the big guys provide." It's going to be tough for them to hold out, and even tougher for new storage startups to break in. But that might be the only thing keeping us from choosing between the Wal-Mart-A and Wal-Mart-B of online storage.

Major Delays, Revamped Beta For Credit-Card Consolidating Gadget Coin 78

Posted by timothy
from the nickelback-quarterback-pedalback dept.
The premise behind Coin is attractive: consolidate credit cards onto a single card-sized gadget. However, on Friday the company announced a delay in the release of its final version from this summer to spring of 2015, and in a way that angered many of the project's crowd-funding backers. The announcement of a delay was not only sudden, and quite close to the previously announced shipping date, but upset those who'd pre-ordered by outlining a confusing beta program that would involve an interim product release — recipients of the beta version (limited to 10,000) would have had to then pay $30 to upgrade to the final product. As CNET reports, the delay until 2015 remains, but with regard to that beta program, Coin has now reversed its stance. The beta program will be free -- meaning preorder customers who opt-in will no longer forfeit the $55 they paid and will still receive the finished Coin product next year. The program will also expand from 10,000 customers to 15,000. Regardless of whether your smartphone is running Apple's iOS or Google's Android operating system, preorder customers can opt-in to Coin's beta program through its app and will be eligible for a device if they fall within the 15,000-person threshold. The order is determined by when you bought your Coin. Coin customers, some who placed orders as far back as November 2013 when the startup first opened its website for preorders, were displeased not so much with the product delay as with the way Coin handled the situation. The company had, as recently as August 14, sent out an update explaining that a long-awaited shipping announcement would arrive at month's end --yet without an indication that it may miss its shipping target.

Slashdot Asks: Cheap But Reasonable Telescopes for Kids? 185

Posted by timothy
from the will-take-credit-for-the-nobel-prize dept.
I am interested in a telescope for the use of some elementary and middle school aged relatives. Older and younger siblings, and parents, would no doubt get some scope time, too. Telescopes certainly come in a range of prices, from cheap to out of this world, and I am purely a duffer myself. But I enjoy looking at the moon and stars with magnification, and think they would, too. What I'm trying to find might be phrased like this: "the lowest priced scope that's reasonably robust, reasonably accurate, and reasonably usable for kids" -- meaning absolute precision is less important than a focus that is easy to set and doesn't drift. Simplicity in design beats tiny, ill-labeled parts or an incomprehensible manual, even if the complicated one might be slightly better when perfectly tuned. I'd be pleased if some of these kids decide to take up astronomy as a hobby, but don't have any strong expectation that will happen -- besides, if they really get into it, the research for a better one would be another fun project. That said, while I'm price sensitive, I'm not looking *only* at the price tag so much as seeking insight about the cluster of perceived sweet spots when it come to price / performance / personality. By "personality" I mean whether it's friendly, well documented, whether it comes intelligently packaged, whether it's a crapshoot as to whether a scope with the same model name will arrive in good shape, etc -- looking at online reviews, it seems many low-end scopes have a huge variance in reviews. What scopes would you would consider giving to an intelligent 3rd or 4th grader? As a starting point, Google has helped me find some interesting guides that list some scopes that sound reasonable, including a few under or near $100. (Here's one such set of suggestions.) What would you advise buying, from that list or otherwise? (There are some ideas that sound pretty good in this similar question from 2000, but I figure the state of the art has moved on.) I'm more interested in avoiding awful junk than I am expecting treasure: getting reasonable views of the moon is a good start, and getting at least some blurry rings around Saturn would be nice, too. Simply because they are so cheap, I'd like to know if anyone has impressions (worth it? pure junk?) of the Celestron FirstScope models, which are awfully tempting for under $50.

Facebook Experimenting With Blu-ray As a Storage Medium 193

Posted by timothy
from the what-do-you-trust-with-your-selfies dept.
s122604 links to CNN's explanation of what may be the future of cold (or at least lukewarm) storage at Facebook, which is experimenting with massive arrays of Blu-Ray discs for seldom-accessed user files. Says the report: The discs are held in groups of 12 in locked cartridges and are extracted by a robotic arm whenever they're needed. One rack contains 10,000 discs, and is capable of storing a petabyte of data, or one million gigabytes. Blu-ray discs offer a number of advantages versus hard drives. For one thing, the discs are more resilient: they're water- and dust-resistant, and better able to withstand temperature swings. Their data can be restored more quickly, and they're easier to transport. Most important, though, is cost. Because the Blu-ray system doesn't need to be powered when the discs aren't in use, it uses 80% less power than the hard-drive arrangement, cutting overall costs in half.

The Tech Fixes the PS3 Still Needs, Eight Years On 99

from the needs-a-cupholder-for-metamucil dept.
An anonymous reader writes "The PlayStation 4 has well and truly arrived, but Sony's still selling its last-gen console by the pallet-load, eight years after first going on sale. Of course, as a new article points out, that's nothing compared to the PS2's astonishing 13 year manufacturing run. To help achieve that, the author outlines some tech fixes the PS3 could still do with, even after all this time, from tighter PS Vita integration, to yes, cross game chat. Can it make it past a decade, too?"

from the starting-from-not-quite-scratch dept.
rtoz writes Google has just announced a new processor for Project Ara. The mobile Rockchip SoC will function as an applications processor, without requiring a bridge chip. A prototype of the phone with the Rockchip CPU, will be available early next year. Via Google+ post, Project Ara team Head Paul Eremenko says "We view this Rockchip processor as a trailblazer for our vision of a modular architecture where the processor is a node on a network with a single, universal interface -- free from also serving as the network hub for all of the mobile device's peripherals." (Project Ara is Google's effort to create an extensible, modular cellphone; last month we mentioned a custom version of Linux being developed for the project, too.)

New EU Rules Will Limit Vacuum Cleaners To 1600W 336

Posted by timothy
from the sucking-power-defined dept.
AmiMoJo writes "New EU rules are limiting vacuum cleaner motors to 1600W from 2014/09/01. The EU summary of the new rules explains that consumers currently equate watts with cleaning power, which is not the case. Manufacturers will be required to put ratings on packaging, including energy efficiency, cleaning efficiency on hard and carpeted floors, and dust emissions from the exhaust. In the EU vacuum cleaners use more energy than the whole of Denmark, and produce more emissions than dishwashers and washing machines."

Virtual Machine Brings X86 Linux Apps To ARMv7 Devices 61

Posted by timothy
from the ever-widening-abstraction-layers dept.
DeviceGuru writes Eltechs announced a virtual machine that runs 32-bit x86 Linux applications on ARMv7 hardware. The ExaGear VM implements a virtual x86 Linux container on ARMv7 computers and is claimed to be 4.5 times faster than QEMU, according to Eltechs. The VM is based on binary translation technology and requires ARMv7, which means it should run on mini-PCs and SBCs based on Cortex-A8, A7, A9, and A15 processors — but sadly, it won't run on the ARM11 (ARMv6) SoC found on the Raspberry Pi. It also does not support applications that require kernel modules. It currently requires Ubuntu (v12.04 or higher), but will soon support another, unnamed Linux distro, according to Eltechs, which is now accepting half price pre-orders without payment obligation.

Ask Slashdot: Where Can I Find Good Replacement Batteries? 131

Posted by Soulskill
from the they're-a-myth dept.
An anonymous reader writes: I have an old phone with a battery that barely works anymore. My current phone's battery is mediocre — I can put up with it, but I've been thinking about getting a new one. My four-year-old ThinkPad holds less of a charge than I'd like, and less than it did when I bought it. In all these cases, the only thing holding me back from buying a new battery is that I'm not sure where to find a good one. Searching for my phone's battery on Amazon (or any major online retailer) yields a dozen results, all fairly cheap. But which are reliable? They all seem to have varying reviews, ranging from "Perfect official factory replacement!" to "Garbage knock-off, worse than the battery I replaced." Part numbers don't seem to help, as the knock-offs replicate those pretty well. I ask you, Slashdot: where can I find a good replacement battery?

A Better Way To Make Mind-Controlled Prosthetic Limbs 27

Posted by Soulskill
from the resistance-is-futile dept.
the_newsbeagle writes: To make a brain-machine interface, you need a way to capture neurons' electric signals. The most precise and most invasive way uses implants that are stuck in the gray matter. The least precise and least invasive way uses EEG sensors stuck to the scalp. But researchers at Johns Hopkins University say there's a third way that gets the best of both worlds, which is not too invasive and fairly precise. They use ECoG systems, in which a mesh of electrodes is placed under the skull, draped over the surface of the cortex.

They're testing their systems on epilepsy patients, who have these ECoG systems inserted anyway while they're waiting for surgery (the electrodes record the source of their seizures). The researchers are capturing these patients' movement commands from their brains, and using them to control robotic limbs. Someday such a system could be used by amputees to control their prosthetic limbs.

How Does Tesla Build a Supercharger Charging Site? 190

Posted by samzenpus
from the power-up dept.
cartechboy writes Tesla's Superchargers are the talk of the electric car community. These charging stations can take a Model S battery pack from nearly empty to about 150 miles of range in around 30 minutes. That's crazy fast, and it's nothing short of impressive. But what does it take to actually build a Tesla Supercharger site? Apparently a lot of digging. A massive trench is created to run high-capacity electric cables before the charging stations themselves are even installed. A diagram and photos of the Electric Conduit Construction build out have surfaced on the Internet. The conduits connect the charging stations to a power distribution center, which in turn is connected to a transformer that provides the power for charging cars. It took 11 days to install the six charging stalls in Goodland, Kansas. If you thought it was a quick process to build a Supercharger station, you were clearly wrong.

How Argonne National Lab Will Make Electric Cars Cheaper 143

from the cheap-charge dept.
ashshy writes Argonne National Lab is leading the charge on next-generation battery research. In an interview with The Motley Fool, Argonne spokesman Jeff Chamberlain explains how new lithium ion chemistries will drive down the cost of electric cars over the next few years. "The advent of lithium ion has truly enabled transportation uses," Chamberlain said. "Because if you remember your freshman chemistry, you think of the periodic table -- lithium is in the upper left-hand corner of the periodic table. Only hydrogen and helium are lighter on an atomic basis."

How many hardware guys does it take to change a light bulb? "Well the diagnostics say it's fine buddy, so it's a software problem."
