How Apple Can Take Its Headphones To the Next Level

Music 196

redletterdave (2493036) writes "Apple is one of the biggest headphone makers in the world thanks to those signature white earbuds that have shipped with every iPod, iPhone, and iPad since 2001. But even two years after earbuds became 'EarPods,' the design could still be improved — and competitors are taking notice. Amazon recently unveiled a new pair of in-ear headphones that are magnetic, tangle-free and $5 cheaper than Apple's $30 EarPods, while smaller startups are promoting their own wireless and customizable 3D-printed earbuds. But Apple has an ace up its sleeve, in the form of patents for a set of headphones with 'one or more integrated physiological sensors' designed to help users keep track of their body stats."

NASA Successfully Tests 'Flying Saucer' Craft, New Parachute

NASA 49

As reported by the Associated Press, via the Washington Post, an update on the promised (and now at least mostly successful) new disc-shaped craft and parachute technology intended for a NASA mission to Mars, though applicable to other space missions as well: A saucer-shaped NASA vehicle launched by balloon high into Earth’s atmosphere splashed down in the Pacific Ocean on Saturday, completing a successful test on Saturday of technology that could be used to land on Mars. Since the twin Viking spacecraft landed on the red planet in 1976, NASA has relied on the same parachute design to slow landers and rovers after piercing through the thin Martian atmosphere. The $150 million experimental flight tested a novel vehicle and a giant parachute designed to deliver heavier spacecraft and eventually astronauts. Despite small problems like the giant parachute not deploying fully, NASA deemed the mission a success. ... [T]he parachute unfurled — if only partially — and guided the vehicle to an ocean splashdown about three hours later. At 110 feet in diameter, the parachute is twice as big as the one that carried the 1-ton Curiosity rover through the Martian atmosphere in 2011. Coatta said engineers won't look at the parachute problem as a failure, but as a way to learn more and apply that knowledge during future tests. ... A ship was sent to recover a "black box" designed to separate from the vehicle and float. Outfitted with a GPS beacon, the box contains the crucial flight data that scientists are eager to analyze. "That's really the treasure trove of all the details," Coatta said. "Pressure, temperature, force. High-definition video. All those measurements that are really key to us to understanding exactly what happens throughout this test."

Tom's Hardware: Microsoft Smartband Coming In October With 11 Sensors

Microsoft 70

New submitter TuxHiggs (2691251) writes "Last month, Forbes wrote that Microsoft was preparing a cross-platform smartwatch with the ability to continuously track your heart rate and sync the data to your devices. A trusted source with knowledge of the development has verified some of that information and provided Tom's Hardware with additional details about the device. The source confirmed previous rumors that the device is cross-platform compatible, and added there would be open APIs as well. The source also confirmed that the display is on the inside of the wrist as opposed to the outside. Design-wise, Microsoft has gone with a slim band design that is said to resemble a thinner, flatter version of the Nike Fuelband. While details about the hardware are scant, the source did reveal that there are 11 sensors under the hood and a mix of chips, including some from TI and Atmel. Finally, the release for this device is apparently set for October."

First time accepted submitter Peter Hudson (3717535) writes Cory Doctorow writes on boingboing.net "BitLit works with publishers to get you free or discounted access to digital copies of books you own in print: you use the free app for Android and iOS to take a picture of the book's copyright page with your name printed in ink, and the publisher unlocks a free or discounted ebook version. None of the Big Five publishers participate as yet, but indies like O'Reilly, Berrett-Koehler, Red Wheel Weiser, Other Press, Greystone, Coach House, Triumph, Angry Robot, Chicago Review, Dundurn, and PM Press (publishers of my book The Great Big Beautiful Tomorrow) are all in."

Secret of the Banjo's Unique Sound Discovered By Nobel Prize-Winning Physicist

timothy posted about a month ago | from the ok-now-tell-us-why-people-like-it dept.

Music 101

KentuckyFC (1144503) writes The banjo is a stringed instrument that produces a distinctive metallic sound often associated with country, folk and bluegrass music. It is essentially a drum with a long neck. Strings are fixed at the end of the neck, stretched across the drum and fixed on the other side. They are supported by a bridge that sits on the drum membrane. While the instrument is straightforward in design and the metallic timbre easy to reproduce, acoustics experts have long puzzled over exactly how the instrument produces its characteristic tones. Now David Politzer, who won the Nobel prize for physics in 2004, has worked out the answer. He says the noise is the result of two different kinds of vibrations. First there is the vibration of the string, producing a certain note. However, the drum also vibrates and this pushes the bridge back and forth causing the string to stretch and relax. This modulates the frequency of the note. When frequency of this modulation is below about 20 hertz, it creates a warbling effect. Guitar players can do the same thing by pushing a string back and forth after it is plucked. But when the modulating frequency is higher, the ear experiences it as a kind of metallic crash. And it is this that gives the banjo its characteristic twang. If you're in any doubt, try replacing the drum membrane with a piece of wood and the twang goes away. That's because the wood is stiffer and so does not vibrate to the same extent. Interesting what Nobel prize-winning physicists do in their spare time.

Are the Hard-to-Exploit Bugs In LZO Compression Algorithm Just Hype?

timothy posted about a month ago | from the you'll-never-feel-it dept.

Security 65

NotInHere (3654617) writes In 1996, Markus F. X. J. Oberhumer wrote an implementation of the Lempel–Ziv compression, which is used in various places like the Linux kernel, libav, openVPN, and the Curiosity rover. As security researchers have found out, the code contained integer overflow and buffer overrun vulnerabilities, in the part of the code that was responsible for processing uncompressed parts of the data. Those vulnerabilities are, however, very hard to exploit, and their scope is dependent on the actual implementation. According to Oberhumer, the problem only affects 32-bit systems. "I personally do not know about any client program that actually is affected", Oberhumer sais, calling the news about the possible security issue a media hype.

KeyStore Vulnerability Affects 86% of Android Devices

timothy posted about a month ago | from the that's-a-lot dept.

Android 71

jones_supa (887896) writes "IBM security researchers have published an advisory about an Android vulnerability that may allow attackers to obtain highly sensitive credentials, such as cryptographic keys for some banking services and virtual private networks, and PINs or patterns used to unlock vulnerable devices. It is estimated that the flaw affects 86 percent of Android devices. Android KeyStore has a little bug where the encode_key() routine that is called by encode_key_for_uid() can overflow the filename text buffer, because bounds checking is absent. The advisory says that Google has patched only version 4.4 of Android. There are several technical hurdles an attacker must overcome to successfully perform a stack overflow on Android, as these systems are fortified with modern NX and ASLR protections. The vulnerability is still considered to be serious, as it resides in one of the most sensitive resources of the operating system."

Cracking Atlanta Subway's Poorly-Encrypted RFID Smart Cards Is a Breeze, Part II

Crime 170

McGruber (1417641) writes In December 2013, Slashdot reported the arrest of seven metro Atlanta residents for allegedly selling counterfeit MARTA Breeze cards, stored-value smart cards that passengers use as part of an automated fare collection system on Atlanta's subway. Now, six months later (June 2014), the seven suspects have finally been indicted. According to the indictment, the co-conspirators purchased legitimate Breeze cards for $1, then fraudulently placed unlimited or monthly rides on the cards. They then sold the fraudulent cards to MARTA riders for a discounted cash price. Distributors of the fraudulent cards were stationed at several subway stations. The indictment claims that the ring called their organization the "Underground Railroad."

Ask Slashdot: SIM-Card Solutions In North America?

Cellphones 146

An anonymous reader writes I'll be returning to North America for July for the first time in a few years, and I'm curious how the phone carrier market compares with the rest of the world. My last time in the U.S., I had to pick up a disposable phone with all kinds of unnecessary environmental waste (charger, packaging, etc.), and *still* had to register it with another domestic (!) phone number and credit card. I don't think I could get a SIM card there without a contract. Anywhere else I travel, picking up a new SIM card with pre-loaded credit is trivially easy. In my last trip to the UK, I just put GBP 10 into a vending machine at the airport and picked up a loaded SIM card for my phone which aldready has my contacts and settings. No ID, no name, no hassle. What are the best options for me in North America (U.S. *and* Canada)?

Bye Bye Aereo, For Now

Television 93

An anonymous reader writes It didn't take long for Aereo to deal with the realities of the U.S. Supreme Court decision. As of 11:30am EDT today Aereo is suspending operations while they go back to U.S. District Court. In order to keep good will with customers during this time, they are refunding the last month's payment for service. curtwoodward (2147628) writes to point out that the decision which has shut down Aereo for now doesn't mean doom for other cloud services: Don't listen to the trolls---the Supremes were very clear that their ruling only applied to Aereo's livestream and things that look just like it. iCloud, Dropbox and friends are fine.

That Toy Is Now a Drone

Toys 268

fluxgate (2851685) writes "A notice from the FAA announced earlier this week just turned a bunch of kids' toys into drones. In the past, the FAA had made the distinction between model aircraft (allowed) and drones (prohibited without special permission) according to whether they were used for recreation (okay) or commercial purposes (verboten). Now they have further narrowed the definition of model aircraft: If you fly it through video goggles, it no longer qualifies. This move eliminates First Person View (FPV) radio control flying. I'm an editor at IEEE Spectrum with a special interest and blogged about this disturbing development as soon as I heard the news."

Is K-12 CS Education the Next Common Core?

timothy posted about a month ago | from the think-I-prefer-google-to-the-nea dept.

Education 113

theodp (442580) writes In an interview with The Washington Post's Lyndsey Layton that accompanied her report on How Bill Gates Pulled Off the Swift Common Core Revolution (the Gates Foundation doled out $233 million in grants to git-r-done), Gates denied that he has too much influence in K-12 education. Despite Gates' best efforts, however, there's been more and more pushback recently from both teachers and politicians on the standards, GeekWire's Taylor Soper reports, including a protest Friday by the Badass Teacher Association, who say Gates is ruining education. "We want to get corporations out of teaching," explained one protester. If that's the case, the "Badasses" probably won't be too pleased to see how the K-12 CS education revolution is shaping up, fueled by a deep-pocketed alliance of Gates, Google, Microsoft, Facebook, and others. Google alone has already committed $90 million to influence CS education. And well-connected Code.org, which has struck partnerships with school districts reaching over 2M U.S. students and is advising NSF-funded research related to the nation's CS 10K Project, will be conducting required professional development sessions for K-12 CS teachers out of Google, Microsoft, and Amazon offices this summer in Chicago, New York City, Boston, and Seattle. So, could K-12 CS Education ("Common Code"?) become the next Common Core?

2600 Distributor Withholds Money, Magazine's Future In Limbo

First time accepted submitter themusicgod1 (241799) writes According to 2600, their distributor (Previously known as "Source Interlink", now recently renamed to "TEN: The Enthusiast Network") has decided to consolidate its resources and is keeping the money retailers paid for the last two issues of the quarterly magazine. 2600, in the meanwhile, is still busy trying to organize the upcoming HOPE X conference. However, according to the link: "In the worst case scenario, being ripped off at this level would make it almost impossible for us to continue publishing. We would have to make a lot of painful choices and cut back on things for no reason other than some outside company's mismanagement. Our readers have supported both our print and digital publications and we've been doing quite well overall." Note: As it says at the linked explanation, 2600 is not a charity, and they're not seeking donations -- but they would like you to buy the magazine (in print or Kindle form), and to attend the upcoming HOPE X conference. (I wish I could make this year's HOPE but can't; as conferences go, HOPE is a wildly good bargain.)

Germany's Glut of Electricity Causing Prices To Plummet

Businesses 365

WIth an interesting followup to the recent news that Germany's power production by at least some measures was briefly dominated by solar production, AmiMoJo (196126) writes Germany is headed for its biggest electricity glut since 2011 as new coal-fired plants start and generation of wind and solar energy increases, weighing on power prices that have already dropped for three years. From December capacity will be at 117% of peak demand. The benchmark German electricity contract has slumped 36% since the end of 2010. "The new plants will run at current prices, but they won't cover their costs" said Ricardo Klimaschka, a power trader at Energieunion GmbH. Lower prices "leave a trail of blood in our balance sheet" according to Bernhard Guenther, CFO at RWE, Germany's biggest power producer. Wind and solar's share of installed German power capacity will rise to 42% by next year from 30% in 2010. The share of hard coal and lignite plant capacity will drop to 28% from 32%.

Why The Korean Government Could Go Open Source By 2020

timothy posted about a month ago | from the file-formats-matter dept.

Open Source 64

An anonymous reader writes As the support for the Microsoft (MS) Windows XP service is terminated this year, the government will try to invigorate open source software in order to solve the problem of dependency on certain software. By 2020 when the support of the Windows 7 service is terminated, it is planning to switch to open OS and minimize damages. Industry insiders pointed out that the standard e-document format must be established and shared as an open source before open source software is invigorated. A similar suggestion that Korea might embrace more open source (but couched more cautiously, with more "should" and "may") is reported on the news page of the EU's program on Interoperability Solutions for European Public Administrations, based on a workshop presentation earlier this month by Korea's Ministry of Science, ICT, and Future Planning. (And at a smaller but still huge scale, the capitol city of Seoul appears to be going in for open source software in a big way, too.)
