How Whisper Tracks Users Who Don't Share Their Location 39

blottsie (3618811) writes "On Thursday, the Guardian reported that secret-sharing app Whisper was tracking users' locations even when they opt-out of sharing their location. [See also this earlier, related story.] Whisper has denied the accusations—but this may be a matter of semantics. Whisper allegedly uses an outdated version of GeoIP by MaxMind, which uses your IP address to estimate your location on a map. Whisper's Chad DePue said in a comment on Hacker News that the tool is "so inaccurate as to be laughable," suggesting that determining something as broad as your country or state won't bother the basic user (and he could be right, but what is and isn't an upsetting degree of user information is another argument entirely)."

The Physics of Why Cold Fusion Isn't Real 350

StartsWithABang writes If you can reach the fabled "breakeven point" of nuclear fusion, you'll have opened up an entire new source of clean, reliable, safe, renewable and abundant energy. You will change the world. At present, fusion is one of those things we can make happen through a variety of methods, but — unless you're the Sun — we don't have a way to ignite and sustain that reaction without needing to input more energy than we can extract in a usable fashion from the fusion that occurs. One alternative approach to the norm is, rather than try and up the energy released in a sustained, hot fusion reaction, to instead lower the energy inputted, and try to make fusion happen under "cold" conditions. If you listen in the right (wrong?) places, you'll hear periodic reports that cold fusion is happening, even though those reports have always crumbled under scrutiny. Here's why, most likely, they always will.

Kickstarter Cancels Anonabox Funding Campaign 76

An anonymous reader writes: On Friday, the controversy surrounding Anonabox reached its zenith with Kickstarter officially canceling the project's funding campaign. Anonabox began with a modest goal of $7,500, but quickly reached its goal 82 times over. Then funders and interested parties began to scrutinize the project's claims, and that's when the project ran into trouble. From hardware that wasn't actually custom-made to software that didn't actually fulfill promises of privacy-focused routing on the internet, the facts regarding Anonabox proved that it was in blatant violation of Kickstarter's rules against false advertising. This project clearly failed, but if the support it initially garnered is any indication, the public is hungry for easy-to-use technology that encrypts and anonymizes all personal internet traffic.

South Korean ID System To Be Rebuilt From Scratch After Massive Leaks 59

AmiMoJo writes: South Korea's national identity card system may need a complete overhaul following huge data thefts dating back to 2004. The government is considering issuing new ID numbers to every citizen over age 17, costing billions of dollars. The ID numbers and personal details of an estimated 80% of the country's 50 million people have been stolen from banks and other targets. Some 20 million people, including President Park Geun-hye, have been victims of a data theft. Citizens are unable to change their credentials, which are used in many different sectors, making them an attractive target for hackers.

High-Tech Walkers Could Help Japan's Elderly Stay Independent 34

jfruh writes: You may have heard that Japan will deal with its aging population by relying more on robots. Osaka startup RT Works is showing what that might mean in practice: not humanoid robotic caregivers, but tech-enhanced versions of traditional tools like walkers. RT Works's walker automatically adjusts to help its user deal with hilly terrain, and can call for help if it moves outside a predefined range.

Fusion and Fission/LFTR: Let's Do Both, Smartly 218

TheRealHocusLocus writes: Disaster preppers have a saying, "two is one and one is none," which might also apply to 24x7 base load energy sources that could sustain us beyond the age of fossil fuel. I too was happy to see Skunkworks' Feb 2013 announcement and the recent "we're still making progress" reminder. I was moved by the reaction on Slashdot: a groundswell of "Finally!" and "We're saved!" However, fusion doesn't need to be the only solution, and it's not entirely without drawbacks.

All nuclear reactors will generate waste via activation as the materials of which they are constructed erode and become unstable under high neutron flux. I'm not pointing this out because I think it's a big deal — a few fusion advocates disingenuously tend to sell the process as if it were "100% clean." A low volume of non-recyclable waste from fusion reactors that is walk-away safe in ~100 years is doable. Let's do it. And likewise, the best comparable waste profile for fission is a two-fluid LFTR, a low volume of waste that is walk-away safe in ~300 years. Let's do it.

Why pursue both, with at least the same level of urgency? Because both could carry us indefinitely. LFTR is less complicated in theory and practice. It is closer to market. There is plenty of cross-over: LFTR's materials challenges and heat engine interface — and the necessity for waste management — are the same as they will be for commercial-scale fusion reactors. To get up to speed please see the 2006 fusion lecture by Dr. Robert Bussard on the Wiffle ball 6 plasma containment, likely the precursor to the Skunkworks approach. And see Thorium Remix 2011 which presents the case for LFTR.

Lead Mir Developer: 'Mir More Relevant Than Wayland In Two Years' 226

M-Saunders writes Canonical courted plenty of controversy with it announced Mir, its home-grown display server. But why did the company choose to go it alone, and not collaborate with the Wayland project? Linux Voice has an interview with Thomas Voss, Mir's lead developer. Voss explains how Mir came into being, what it offers, and why he believes it will outlast Wayland.

Tesla Teardown Reveals Driver-facing Electronics Built By iPhone 6 Suppliers 158

Lucas123 writes: The Tesla Model S gets attention because it's an EV that can go from from 0 to 60 mph (96 km/h) in 4.2 seconds and can travel 265 miles on a single charge. But, a teardown of the vehicle by IHS Technology has also revealed that Elon Musk avoided third-party design and build routes used traditionally by auto makers and spared no expense on the instrument cluster and infotainment (head unit) system, which is powered by two 1.4Ghz, quad-core NVIDIA Tegra processors. IHS called the Tesla's head unit the most sophisticated it's ever seen, with 1,000 more components than any it has previously analyzed. A bill of materials for the virtual instrument cluster and the premium media control unit is also roughly twice the cost of the highest-end infotainment unit examined by IHS.

Python-LMDB In a High-Performance Environment 98

lkcl writes: In an open letter to the core developers behind OpenLDAP (Howard Chu) and Python-LMDB (David Wilson) is a story of a successful creation of a high-performance task scheduling engine written (perplexingly) in Python. With only partial optimization allowing tasks to be executed in parallel at a phenomenal rate of 240,000 per second, the choice to use Python-LMDB for the per-task database store based on its benchmarks, as well as its well-researched design criteria, turned out to be the right decision. Part of the success was also due to earlier architectural advice gratefully received here on Slashdot. What is puzzling, though, is that LMDB on Wikipedia is being constantly deleted, despite its "notability" by way of being used in a seriously-long list of prominent software libre projects, which has been, in part, motivated by the Oracle-driven BerkeleyDB license change. It would appear that the original complaint about notability came from an Oracle employee as well.

How Curved Spacetime Can Be Created In a Quantum Optics Lab 89

KentuckyFC writes: One way to explore the link between quantum mechanics and general relativity is to study the physics that occurs on a small scale in highly curved spacetimes. However, these conditions only occur in the most extreme environments such as at the edge of black holes or in the instants after the Big Bang. But now one physicist has described how it is possible to create curved spacetime in an ordinary quantum optics lab.

The idea is based on optical lattices, which form when a pair of lasers interfere to create an eggbox-like interference pattern. When ultracold atoms are dropped into the lattice, they become trapped like ping pong balls in an eggbox. This optical trapping technique is common in labs all over the world. However, the ultracold atoms do not stay at a fixed location in the lattice because they can tunnel from one location to another. This tunneling is a form of movement through the lattice and can be controlled by changing the laser parameters to make tunneling easier or more difficult.

Now, a physicist has shown that on a large scale, the tunneling motion of atoms through the lattice is mathematically equivalent to the motion of atoms in a quantum field in a flat spacetime. And that means it is possible to create a formal analogue of a curved spacetime by changing the laser parameters across the lattice. Varying the laser parameters over time even simulates the behavior of gravitational waves. Creating this kind of curved spacetime in the lab won't reveal any new physics but it will allow researchers to study the behavior of existing laws under these conditions for the first time. That's not been possible even in theory because the equations that describe these behaviors are so complex that they can only be solved in the simplest circumstances.

Chemists Grow Soil Fungus On Cheerios, Discover New Antifungal Compounds 77

MTorrice writes: Many drugs that treat bacterial and fungal infections were found in microbes growing in the dirt. These organisms synthesize the compounds to fend off other bacteria and fungi around them. To find possible new drugs, chemists try to coax newly discovered microbial species to start making their arsenal of antimicrobial chemicals in the lab. But fungi can be stubborn, producing just a small set of already-known compounds.

Now, one team of chemists has hit upon a curiously effective and consistent trick to prod the organisms to start synthesizing novel molecules: Cheerios inside bags. Scientists grew a soil fungus for four weeks in a bag full of Cheerios and discovered a new compound that can block biofilm formation by an infectious yeast. The chemists claim that Cheerios are by far the best in the cereal aisle at growing chemically productive fungi.

OS X 10.10 Yosemite Review 305

An anonymous reader writes: With the release of OS X 10.10 Yosemite, Ars Technica has posted one of their extremely thorough reviews of the OS's new features and design changes. John Siracusa writes that Yosemite is particularly notable because it's the biggest step yet in Apple's efforts to bring OS X and iOS together — new technologies are now being added to Apple's two operating systems simultaneously. "The political and technical battles inherent in the former two-track development strategy for OS X and iOS left both products with uncomfortable feature disparities. Apple now correctly views this as damage and has set forth to repair it." Yosemite's look and feel has undergone significant changes as well, generally moving toward the flat and compact design present in iOS 7 & 8. Spotlight and the Notifications Center have gotten some needed improvements, as did many tab and toolbar interfaces.

Siracusa also takes a look a Swift, Apple's new programming language: "Swift is an attempt to create a low-level language with high-level syntax and semantics. It tackles the myth of the Sufficiently Smart Compiler by signing up to create that compiler as part of the language design process." He concludes: "Viewed in isolation, Yosemite provides a graphical refresh accompanied by a few interesting features and several new technologies whose benefits are mostly speculative, depending heavily on how eagerly they're adopted by third-party developers. But Apple no longer views the Mac in isolation, and neither should you. OS X is finally a full-fledged peer to iOS; all aspects of sibling rivalry have been banished."

Mixing Agile With Waterfall For Code Quality 133

jones_supa writes: The 2014 CAST Research on Application Software Health (CRASH) report states that enterprise software built using a mixture of agile and waterfall methods will result in more robust and secure applications than those built using either agile or waterfall methods alone. Data from CAST's Appmarq benchmarking repository was analyzed to discover global trends in the structural quality of business application software. The report explores the impact of factors such as development method, CMMI maturity level, outsourcing, and other practices on software quality characteristics that are based upon good architectural and coding practices. InfoQ interviewed Bill Curtis, Senior Vice President and Chief Scientist at CAST, about the research done by CAST, structural quality factors, and mixing agile and waterfall methods.
