Intel Details Power Management Advancements in Haswell 113

MojoKid writes "Intel's next-generation CPU architecture, codenamed Haswell, puts heavy emphasis on reducing power consumption. Pushing Haswell down to a 10W TDP is an achievement, but hitting these targets requires collaboration. Haswell will offer finer-grained control over areas of logic that were previously either on or off, up to and including specific execution units. These optimizations are impressive, particularly the fact that idle CPU power is approaching tablet levels, but they're only part of the story. Operating system changes matter as well, and Intel has teamed up with Microsoft to ensure that Windows 8 takes advantage of current and future hardware. Haswell's 10W target will allow the chip to squeeze into many of the convertible laptop/tablet form factors on display at IDF, while Bay Trail, the 22nm, out-of-order successor to Clover Trail, arrives in 2013 as well. Not to mention the company's demonstration of the first integrated digital WiFi radio. Folks have been trading blows over whether Intel could compete with ARM's core power consumption. Meanwhile, Santa Clara has been busy designing many other aspects of the full system solution for low power consumption and saving a lot of wattage in the process." It's mildly amusing that Windows 8 is the first version to gain dynamic ticks, something Linux has had working since around 2007.

Ask Slashdot: Best Protection Plan For Your Phone? 225

First time accepted submitter nastav writes "Now that I'm eagerly awaiting the delivery of my new shiny iPhone 5, I'm faced with a dilemma — SquareTrade, Applecare Plus, or some other insurance option? I have used SquareTrade in the past for my iPhone 3GS and iPhone 4 (I skipped iPhone 4S). It provided Accidental Damage Handling (ADH) for the iPhone before Apple introduced its own version of ADH. I've had the opportunity to file claims with SquareTrade multiple times, and they handled it quickly and professionally each time. Now that there is a product from Apple itself, I'm not sure which one to get. They are priced similarly (~$100 for a two-year plan, $50 deductible for each ADH incident) Apple limits the number of ADH claims to two, whereas SquareTrade (AFAIK) limits the number of claims to the 'value of the product,' which translates to approx. 600 USD in coverage (or about 4 ADH claims). I've tried reading many comparison articles on the internet without definitive answers. I'm hoping that the tech-savvy folks on Slashdot would help out with a discussion on pros and cons of each, and perhaps add other options into the mix."

Towards a 50% Efficient Solar Cell 129

necro81 writes "IEEE Spectrum magazine has a feature article describing DARPA-funded work towards developing a solar cell that's 50% efficient, for a finished module that's 40% efficient — suitable for charging a soldier's gadgets in the field. Conventional silicon and thin-film PV tech can hit cell efficiencies of upwards of 20%, with finished modules hovering in the teens. Triple-junction cells can top 40%, but are expensive to produce and not practical in most applications. Current work by the Very High Efficiency Solar Cell program uses optics (dichroic films) to concentrate incoming sunlight by 20-200x, and split it into constituent spectra, which fall on many small solar cells of different chemistries, each tuned to maximize the conversion of different wavelengths."

Japan Aims To Abandon Nuclear Power By 2030s 214

mdsolar writes "Reuters reports that the Japanese government said it 'intends to stop using nuclear power by the 2030s, marking a major shift from policy goals set before last year's Fukushima disaster that sought to increase the share of atomic energy to more than half of electricity supply. Japan joins countries such as Germany and Switzerland in turning away from nuclear power ... Japan was the third-biggest user of atomic energy before the disaster. In abandoning atomic power, Japan aims to triple the share of renewable power to 30 percent of its energy mix, but will remain a top importer of oil, coal and gas for the foreseeable future. Prime Minister Yoshihiko Noda's unpopular government, which could face an election this year, had faced intense lobbying from industries to maintain atomic energy and also concerns from its major ally, the United States, which supplied it with nuclear technology in the 1950s.' Meanwhile, the U.S. nuclear renaissance appears to be unraveling."

How Viable Is Large Scale Wind Energy? 345

New submitter notscientific writes "Renewable sources of energy are obviously a hit but they have as yet failed to live up to the hype. A new study in Nature Climate Change shows however that there is more than enough power to be harnessed from the wind to sustain Earth's entire population... x200! To generate energy from the wind, we may however need to set up wind farms at altitudes of 200-20,000 metres. To be fair, the study is purely theoretical and does not look at the feasibility of such potential wind farms. Regardless, the paper does provide a major boost to backers of wind-generated energy. Science has confirmed that the sky's the limit."

Ancient Egyptian Tech May Be Key To Printing 3D Ceramics 138

Zothecula writes "We like to think of technology as always being forward looking. It's supposed to be about nanoparticles and the Cloud, not steam engines and the telephone exchange. But every now and again the past reaches out, taps the 21st century on the shoulder and says, 'Have a look at this.' That's what happened to Professor Stephen Hoskins, Director of the University of West England, Bristol's Centre for Fine Print Research. He is currently working on a way of printing 3D ceramics that are self-glazing, thanks to a 7,000-year old technology from ancient Egypt."

Ask Slashdot: What Tech For a Sailing Ship? 340

Razgorov Prikazka writes "There is a lot of technology involved in sailing these days. EPIRB, FHV-DSC, GPS, NAVTEX, Inmarsat, fishfinders/depth sounders, different kinds of radar (with MARPA or ATA) — you name it and there are dozens of manufacturers out there willing to provide, all of them with a range of different products. Right now I am planning a 'round-the-world-trip,'' and my ship (an 18-meter Skerry Cruiser sailing yacht) is in its early construction phase, so I need to shop for some hi-tech gear and, basically, I got lost in all the possibilities. What kind of hardware would you recommend as necessary for a trip of this kind? What would you have installed in your ship in order to have a safe trip?"

TACC "Stampede" Supercomputer To Go Live In January 67

Nerval's Lobster writes "The Texas Advanced Computing Center plans to go live on January 7 with "Stampede," a ten-petaflop supercomputer predicted to be the most powerful Intel supercomputer in the world once it launches. Stampede should also be among the top five supercomputers in the TOP500 list when it goes live, Jay Boisseau, TACC's director, said at the Intel Developer Forum Sept. 11. Stampede was announced a bit more than two years ago. Specs include 272 terabytes of total memory and 14 petabytes of disk storage. TACC said the compute nodes would include "several thousand" Dell Stallion servers, with each server boasting dual 8-core Intel E5-2680 processors and 32 gigabytes of memory. In addition, TACC will include a special pre-release version of the Intel MIC, or "Knights Bridge" architecture, which has been formally branded as Xeon Phi. Interestingly, the thousands of Xeon compute nodes should generate just 2 teraflops worth of performance, with the remaining 8 generated by the Xeon Phi chips, which provide highly parallelized computational power for specialized workloads."

While teleportation remains elusive, several once-fictional technologies are changing the way people live and work. Here are some ways in which we're approaching the gizmos that Star Trek demonstrated. Speech recognition? Check. Holodeck? Sort of. Replicator? Workin' on it."

Intel Encodes Data In Flickering LEDs (and Shows Off Other Bright Ideas) 65

darien writes "On the day before the Intel Developer Forum opens in San Francisco, Intel has been showing off some of its current research projects, including a system for encoding data in apparently steady light sources, a Kinect-based projected 'touch interface' that works on any surface and an ambitious signage concept that could revolutionise your weekly shop." My favorite thing about light-based networking is that it's the basis of a certain strain of (all too plausible, all too often) conspiracy theory. ("The modern LED 'eco-friendly' light bulb is also a two-way communications device." — easy to believe, since many of them can be. )

One Company's Week-Long Interview Process 362

jfruh writes "What's the longest tech interview you've had to sit through — two hours? Eight? Ruby on Rails devs who want to work for Hashrocket need to travel to Florida and do pair-programming on real projects for a week before they can be hired. The upside is that you'll be put up in a beachfront condo for the week with your significant other; the downside is that you'll be doing real work for a week for little or no pay and no guarantee of a job slot."

Election Tech: In Canada, They Actually Count the Votes 500

Presto Vivace writes with this outline of what voting can look like while remaining countable and anonymous — and how it does look north of the U.S. border. "In Canada, they use hand-marked paper ballots, hand counted in public. Among other things, that process means that we can actually be sure who won. And if the elections of 2000 and 2008 are any guide, and the race stays as close as the pollsters sat it is, we might, on Wednesday, November 7, not be sure who won." Any Canadians among our readers who want to comment on this?"

Judge Rules Sniffing Open Wi-Fi Networks Is Not Wiretapping 308

An anonymous reader writes "Ars reports on a decision from a district judge in Illinois, who ruled that sniffing traffic on an unencrypted Wi-Fi network is not wiretapping. In the ruling, the judge points out an exception in the Wiretap Act which allows people to 'intercept or access an electronic communication made through an electronic communication system that is configured so that such electronic communication is readily accessible to the general public.' He concludes that 'the communications sent on an unencrypted Wi-Fi network are readily available to the general public.' Orin Kerr disagrees with the ruling, saying that the intent of the person setting up the network is important: 'No one suggests that unsecured wireless networks are set up with the goal that everyone on the network would be free to read the private communications of others.'"

Rhombus Tech A10 EOMA-68 CPU Card Schematics Completed 155

lkcl writes "Rhombus Tech's first CPU Card is nearing completion and availability: the schematics have been completed by Wits-Tech. Although it appears strange to be using a 1ghz Cortex A8 for the first CPU Card, the mass-volume price of the A10 was lower than other offerings. Not only does the A10 classify as 'good enough' (in combination with 1GB of RAM), Allwinner Tech is one of the very rare China-based SoC companies willing to collaborate with Software (Libre) developers without an enforced (GPL-violating) NDA in place. Overall, it's the very first step in the right direction for collaboration between Software (Libre) developers and mass-volume PRC Factories. There will be more (faster, better) EOMA-68 CPU Cards: this one is just the first."

Ask Slashdot: How Would You Fix the Linux Desktop? 1154

itwbennett writes "Slashdot readers are familiar with the Torvalds/de Icaza slugfest over 'the lack of development in Linux desktop initiatives.' The problem with the Linux desktop boils down to this: We need more applications, and that means making it easier for developers to build them, says Brian Proffitt. 'It's easy to point at solutions like the Linux Standard Base, but that dog won't hunt, possibly because it's not in the commercial vendors' interests to create true cross-distro compatibility. United Linux or a similar consortium probably won't work, for the same reasons,' says Proffitt. So, we put it to the Slashdot community: How would you fix the Linux desktop?"

Do Tech Entrepreneurs Need To Know How To Code? 202

An anonymous reader writes "Learning to write code has become something of a trendy thing to do. New York City Mayor Michael Bloomberg has said he intends to learn code this year. Estonia has recently announced a scheme with the aim of getting every 6-year-old in the Baltic state to learn programming skills. The demand has spawned a number of start-ups offering coding lessons. General Assembly, which teaches off-line courses, has recently opened up in London and is recruiting ahead of a launch in Berlin. On-line education site Codecademy landed $10 million to expand from its home base in New York. Zach Simms, the 22-year-old co-founder, said in an earlier interview with The Wall Street Journal that not everyone has to learn to code, but everybody 'needs to learn the notions of algorithms, realizing what you can use code for.' But do they?"

Apple Denies FBI Had Access To UDIDs 104

First time accepted submitter WIn5t0n writes "Just a day after the alleged leak of 12million Apple UDID's, both Apple and FBI have denied the story that Anonymous, a global hacking community, gained access to the files by hacking into an FBI laptop through a Java vulnerability. Earlier this morning the FBI claimed that, even though the agent cited in Anonymous's story is an actual FBI operative, neither he nor anyone else in the agency has or has had access to Apple device information. This afternoon Apple followed up on the FBI's statement, with an unidentified Apple representative claiming that, 'The FBI has not requested this information from Apple, nor have we provided it to the FBI or any organization.' It should also be noted that while the hackers claim to have accessed 12 million UDID's, only 1 million were publicly released. The Apple representative who made the previous statements also said that, 'Apple has replaced the types of identifiers the hackers appear to have gotten and will be discontinuing their use.' Even though neither Anonymous nor the FBI/APPLE will admit where the data actually came from, it does appear that at least some of the leaked UDID's are legit and can be tied back to current, privately owned devices. So far no information besides the devices UDID, DevToken ID, and device name has been released, however the original hackers claimed that some devices were tied to details as exact as phone numbers and billing addresses."
Censorship

Why Apple Should Stop Censoring Apps 144

An anonymous reader writes "ReadWriteWeb makes the case that Apple should stop censoring submissions to the App Store. The company made headlines last week for banning an app showing the locations of drone strikes in Pakistan, Yemen, and Somalia. The article says Apple should restrict its bans to apps that have terrible functionality or a poor UI, and 'get out of the business of censorship.' Quoting: 'Last year in Syria, antigovernment activists began using an iPhone app to disseminate news, maps, photos and videos about the conflict in a country that doesn't exactly rank highly for its press freedom. Mobile tech in the hands of Syrian dissidents proved enough of a nuisance that the government banned the iPhone in late 2011, presumably to quash content that the regime found, um, objectionable. This example raises a few questions. First, why are pins on a map more objectionable than photos and video clips from a war zone? Why does content that effectively agitates for one government to be overthrown make the cut, while content that may make another government look bad (depending on one's own perspective) doesn't? Is Apple taking sides in international conflicts? Perhaps more disturbing is the notion that, were Apple to apply these standards consistently, apps like the one used by Syrian dissidents — and perhaps some news apps — would be barred from the App Store as well.'"

Oracle To Pay Google $1 Million For Lawyer Fees In Failed Patent Case 97

eldavojohn writes "You may recall the news that Google would not be paying Oracle for Oracle's intellectual property claims against the search giant. Instead, Google requested $4.03 million for lawyer fees in the case. The judge denied some $2.9 million of those fees and instead settled on $1.13 million as an appropriate number for legal costs. Although this is relative peanuts to the two giants, Groklaw breaks the ruling down into more minute detail for anyone curious on what risks and repercussions are involved with patent trolling."

Xen-Based Secure OS Qubes Hits 1.0 175

Orome1 writes "Joanna Rutkowska, CEO of Invisible Things Lab, today released version 1.0 of Qubes, a stable and reasonably secure desktop OS. It is the most secure option among the existing desktop operating systems — even more secure than Apple's iOS, which puts each application into its own sandbox and does not count on the user to make security decisions. Qubes will offer users the option of using disposable virtual machines for executing tasks they believe could harm their computer. These VMs will be lightweight, easily and extremely speedily created and booted, and would be just as easy to discard." First covered back in 2010. See some screenshots of the X11 part in action (and they say displaying clients from multiple "hosts" isn't useful...)
