It'd be nice to see ARM being able to play in the HPC field.

The battlefield is littered with the bodies of those that have tried before... I know I worked with Calxeda when they were trying to crack into supercomputers with their 40-core systems.

At the end of the day, the flops/watt was considerably better with Intel's Xeon (and much better with Xeon Phi). But that was 2012...

Submission + - Second Tesla Autopilot Crash Under Review By US Regulators (time.com)

An anonymous reader writes: The Wall Street Journal and many other publications are reporting that U.S. auto-safety regulators are currently reviewing a second crash that occurred while Tesla's Autopilot mode was activate. The Detroit Free Press reports that a Michigan art gallery owner told police that he survived a rollover crash that happened when his Tesla Model X was in self-driving mode last Friday. The newspaper didn't disclose any additional details regarding what led up to the accident and whether or not the driver was to blame. Last week, it was reported that U.S. regulators were investigating Tesla after a fatal crash occurred involving a vehicle using the Autopilot mode. Tesla said in a statement after that incident, "This is the first known fatality in just over 130 million miles where Autopilot was activated." They also said Autopilot "is an assist feature that requires you to keep your hands on the steering wheel at all times."

Submission + - Redis: Over 6,000 Installations Compromised (riskbasedsecurity.com)

An anonymous reader writes: If you are running a Redis server, better check the security settings. After reading the documentation it becomes clear, that Redis is shipped for maximum performance and not with security in mind. Meaning that by default, Redis has no authentication or security mechanism enabled, and any security mechanisms must be implemented by the end user.

Submission + - SPAM: C++17 standard now feature complete

need4speed writes: The C++17 standard is now feature complete, but there is more work to be done, specifically around features that were put off and are destined to be implemented as compiler add-ons.

“C++17 evolves the standard further, the tools for standardization have matured and are working,” Jens Weller, a C++ evangelist wrote. “Probably the biggest gain for C++. Those who would like to add certain features to the next C++ Standard (a.k.a. C++NEXT/C++20), should now start to make their plans.”

Right now, one of the biggest additions to the language is [spam URL stripped], which is like a type-safe union implementation. In the future, this addition can be used to build pattern matching.

Submission + - Test of America's homeland missile defense system was an epic fail ... (latimes.com)

schwit1 writes: The system, known as GMD, has cost taxpayers more than $40 billion since it was declared operational in 2004. It is being expanded at a rapid pace despite stubborn technical problems that have undermined its reliability.

In carefully scripted tests, the system has failed to intercept and destroy mock warheads about half the time.

Project engineers for the Jan. 28 test had planned for the interceptor to fly within a narrow “miss distance” of its target to test the new thrusters’ effectiveness.

The missile agency issued a news release that day touting a “successful flight test.” The agency’s lead contractors were no less effusive. Aerojet Rocketdyne Inc., maker of the thrusters, said the new model “successfully performed its mission-critical role.”

That is not what happened. The closest the interceptor came to the target was a distance 20 times greater than what was expected, said the Pentagon scientists, who spoke on condition they not be identified.

“The mission wasn’t successful,” one of the scientists said. “Did the thruster perform as expected? No, it did not provide the control necessary for a lethal impact of an incoming threat.” A second scientist said the claims of success by the Missile Defense Agency and the contractors were “hyperbole, unsupported by any test data.”

A company could equally easily put in the small print of their contract that anyone purchasing one of their products must give up their first-born child to go and work in some factory in the far east for no pay, working as child slave labour.

You know, if even a fraction of the things I've heard about Samsung are true... that is exactly the kind of thing I'd expect from them.

Comment Re:Headphone jack is important (Score 1) 289

There is an open standard for a connection that every mfg can (and does) use, and has been for years: USB-A.

There already are combination DAC/Amplifier units for smartphones. Most new car radios have them built-in, as well as many high end headphone DAC/Amplifiers. Every one of them accepts a standard USB-A cable, and everybody's phone has a cable for USB-A.

USB-C is starting to replace USB-A, and I expect the trend to accelerate.

The dongle for Lightning to USB-C would probably look similar to the in-line volume knobs on a 3.5 mm cord; not ideal, but not horrid either. Lightning, at least, has the ability to power a headphone amp from the iDevice's battery; I imagine USB-C does as well. I don't know if the standard allows a device using Micro-USB to switch from being a power sink to a power source.

Electronics companies will go nuts over it, because they can all upsell super-premium DACs and amplifiers, assembled by the most attractive supermodels, and sealed using precious bodily fluids from rock stars.

Comment Re:and the headphone jack will be removed (Score 1) 289

In general, I agree completely - I want an analog headphone jack.

Removing it is not just about the headphone jack, though. Sure, there is the size of the jack, but you also have to have the D/A chip and a nice, clean analog amplifier to drive the headphones - the amp has its own design constraints (needs to be located in a place it won't pick up noise from the rest of the phone), as well as space to hold it.

Ditching the headphone jack (and amp) can allow a decent amount of internal volume to be re-purposed. The D/A and amplifier is moved outside the phone.

Oddly enough, high-end ("audiophile" snake-oil) versions already exist for existing smartphones - you plug in your phone (Android is also supported!) via USB to the D/A+Amp, and then plug in your headphones. Many of the newer car stereos can connect directly via USB and do the same thing.

Consumer electronics is always looking for the next way to sell you the same thing again -- "digital" headphones would be heavily marketed by every brand in the business.

Assuming, of course, that Apple really is removing the headphone jack.

I'd argue that EAX wasn't really that sophisticated; it had a library of cheap DSP effects that was an improvement over nothing, but had no ability to transition from one to another, and didn't handle environments other than closed ones.

It turned out to be far more flexible and pragmatic to do it all in software, where developers weren't constrained by a single, indifferent hardware developer. (With bonus points for working everywhere, instead of requiring a single-source product). Creative was never interested in an API that would allow anybody's hardware to use it.

Insert OpenAL: Loki Software implemented an open and cross-platform API for 3D audio, with software fallback.For a while, OpenAL was one of the audio libraries of choice - Doom 3, BioShock, Unreal Tournament, Jedi Knight, Battlefield 2. Creative even deprecated EAX in favor of OpenAL.

But game makers were pragmatic and started doing the DSP in software, since it would work everywhere instead of being specific to Creative hardware.

I don't even know of modern software that supports anything like EAX in hardware anymore. (Well, other than Creative's Demos...)

Comment Re:Pls decouple saving money & saving environm (Score 1) 630

From what I've seen, electric more or less breaks even in terms of energy cost vs gasoline - the cost per mile to charge the battery is tiny compared to the cost to refuel the car. However, the battery itself eventually needs replacement, and isn't cheap. Overall, it comes down to paying incrementally (fuel) or in lump sums (battery).

That said, energy source is only one part of a vehicle's cost per mile of ownership (albeit a substantial one).

Maintenance is an area where electric cars may have a substantial advantage - the number of moving (and wearing) parts is much, smaller for an electric vehicle. You don't have to worry about liquid cooling, oil changes, catalytic converters, mufflers, fuel injectors, spark plugs, camshafts, valve heads, head gaskets, fuel pumps, oil pumps, and most of the transmission (most electrics are direct drive).

Electric cars have quite a number of cost advantages that you'll never achieve with an internal combustion engine.

I question the validity of this list, if only because a few are definitely not green, as well as being decades old multinational corporations.

Schneider electric, for example- they make circuit breakers and uninterruptible power supplies, servos, and industrial power distribution (ie. wire & transformers), among a great many other things -- plain old normal electrical infrastructure. They even own APC, who is a longtime producer of UPS's for offices & datacenters -- nobody likes downtime.

Johnson Controls? One of the 800 pound multinational gorillas in the commercial HVAC business? Are you fraking kidding me? The best they can say for being "green" is trying to make a more efficient HVAC system -- you know, R&D for a competitive advantage.

A123 makes lithium batteries - a product in everything from portable electronics to power tools (seriously - who doesn't have an electric screwdriver or drill?) There are a ton of lithium battery manufacturers, and it's no surprise that one manufacturer will be out-competed by another. They don't even clam to be green. The big thing with A123 batteries is they charge fast, and tolerate abuse without exploding. Is not exploding the new green?
