Silicon Brains That Think As Fast As a Fly Can Smell 84

Nerval's Lobster writes "Researchers in Germany have discovered what they say is a way to get computers to do more than execute all the steps of a problem-solving calculation as fast as possible – by getting them to imitate the human brain's habit of finding shortcuts to the right answer. A team of scientists from Freie Universität Berlin, the Bernstein Center Berlin, and Heidelberg University have refined the idea of parallel computing into one they describe as neuromorphic computing. In their design, a whole series of processors designed as silicon neurons rather than ordinary CPUs are linked together in a network similar to the highly interconnected mesh that links nerve cells in the human brain. Problems fed into the neuro mesh are broken up and processed in parallel, but not always using the same process. The method by which neuromorphic processors handle problems varies with the way they're linked together, as is the case with neurons in the brain. The chips are designed to copy the layout and functions of brain cells, but the way they're interconnected is based on another highly efficient biological model. 'The design of the network architecture has been inspired by the odor-processing nervous system of insects,' said one of the researchers. 'This system is optimized by nature for a highly parallel processing of the complex chemical world.' In tests using real-world datasets, the prototype was able to match the performance of specialized Bayeseian pattern-matching systems. Even better, the stable decisions reached by 'output neuron populations' take approximately 100 milliseconds, which is the same speed required by the insect nervous systems on which the network design is based, according to the paper."

No they weren't. Cellphones were cool from the start. At least, around here anyway. Everyone wanted one. The problem with glass is the same with bluetooth headsets. People ware them even when they're not using them... which makes you look like a douche. Once Google has these embedded in regular glasses this will stop being an issue.

Agree with the first part, but on BlueTooth headsets - what's one supposed to do with them, take them off and pocket them? That risks losing them. I leave mine in place, even when turned off, when I'm out and about. 'Cause I know I'd lose it otherwise.

Maybe it helps that I grew up in a household where hearing aids were worn by a family member, so having something in the ear was normal. On the other hand, I hated wearing ear buds for the longest time, 'til I recognized the usefulness of them.

Submission + - Edward Snowden says NSA engages in industrial espionage (www.cbc.ca) 2

Maow writes: Snowden has been interviewed by a German TV network and stated that the NSA is involved in industrial espionage, which is outside the range of national security.

He claims that Siemens is a prime example of a target for the data collection.

I doubt this would suprise AirBus or other companies, but it shall remain to be seen what measures global industries take (if any) to prevent their internal secrets from falling into NSA's — and presumably American competitors' — hands.

Submission + - Chinese Moon Rover Said Early Good Bye

Submission + - Gone are the days when somebody could learn to be a sys admin at home! 3

An anonymous reader writes: After looking at many job boards it seems that most of the jobs require knowledge of "professional" VMs and cloud based services. The man/woman sitting at home does not usually "play" with VMs like how a real company would use VMs. The man/woman sitting at home usually does not have access to cloud services and would usually have to pay a considerable sum to "get cloud services" to learn about them. No more sys admin at home! In the "old" days you could learn about SCSI and IDE and networking and learn to program in say Perl or PHP — these would get you in the door at many companies. Not anymore!

Schiller Says Apple Is the Last PC Maker From the Mac Era, Forgets About HP 474

An anonymous reader writes "Philip Schiller, Apple's senior vice president of worldwide marketing, recently claimed that Apple is the only computer company left from the early days of the Mac. Unfortunately for him, HP still exists. "Every company that made computers when we started the Mac, they're all gone," Schiller told Macworld in an interview on Apple's Cupertino campus. 'We're the only one left.' I'm sorry Apple, but when exactly did HP declare bankruptcy? We contacted an HP spokesperson for a statement on Apple's ridiculous claim and were pointed to its timeline history page."

Google Co-Opts Whale-Watching Boat To Ferry Employees 373

theodp writes "Purportedly intended to defuse tensions over gentrification that have led to blockades and vandalism of Google's ubiquitous shuttles (video), which make use of public San Francisco bus stops (map), Wired reports that Google is now chartering a ferry to take its workers from SF to Silicon Valley. 'We certainly don't want to cause any inconvenience to SF residents, and we're trying alternative ways to get Googlers to work,' Google explained. Inconveniencing whale-seeking visitors to The Aquarium of the Pacific, however, is apparently not considered evil. After learning that Google had co-opted the $4 million, 83-foot, 150-passenger whale-watching catamaran MV/Triumphant to ferry as few as 30-40 Googlers to work, some expressed concerns on Facebook that Google would be The Grinch That Stole Whale Watching Season (not to worry; the boat's slated to make its 'triumphant' return to Long Beach after Google's '30-day trial')."

Comment Re:Maybe they're not stars.... (Score 4, Informative) 150

A million miles per hour is not all that much.

All the galaxies in our neighborhood are also rushing at a speed of nearly 1,000 kilometers per second (2,236.936 miles per hour) towards a structure called the Great Attractor, a region of space roughly 150 million light-years away.

I think they're calling them fast based on the relative speed to the galaxy that they're being ejected from / passing though.

Astrophysicists calculate that a star must get a million-plus mile-per-hour kick relative to the motion of the galaxy to reach escape velocity.

The diagram in TFA seems to indicate that these stars are not originating inside the galaxy, which to me raises the question, from whence do they come?

This image makes it appear the stars are mostly passing through the disk of the galaxy. I may be reading too much into the length of the coloured lines though.

Comment Re:U.S. courts 'extradited' Canadian bank records? (Score 1) 184

That court case did nothing of the sort - it was a court case against a local US bank subsidiary asking for records of other subsidiaries in the Bahamas and Cayman Islands.

I came in here to address this issue.

An interesting quote (emphasis mine) from the linked-to case:

The nationality of the Bank is Canadian, but its presence is pervasive in the United States.[18] The Bank has voluntarily elected to do business in numerous foreign host countries and has accepted the incidental risk of occasional inconsistent governmental actions. It cannot expect to avail itself of the benefits of doing business here without accepting the concomitant obligations. As the Second Circuit noted years ago, "If the Bank cannot, as it were, serve two masters and comply with the lawful requirements both of the United States and Panama, perhaps it should surrender to one sovereign or the other the privileges received therefrom."

Over all I do hope that more data is moved to Canada (hence more jobs here), and the Canadian governments, federal and provincial, strengthen their determination (and regulations) to keep sensitive citizens' data out of the USA.

How about a nice, fat trans-Canada fibre optic cable, all within our borders? I imagine the spending on the advertisements for the "Canada Action Plan" would've paid for a good deal of it...

CES: Laser Headlights Edge Closer To Real-World Highways 295

jeffb (2.718) writes "Audi will display laser-headlight technology on a concept car at the 2014 Consumer Electronics Show, joining BMW, whose plug-in hybrid should reach production in 2014. A November article on optics.org describes the technology in more detail. This approach does not scan or project a 'laser beam' from the car; instead, it uses blue lasers as highly efficient light emitters, and focuses their light onto a yellow phosphor, producing an extremely intense and compact white light source and then forming that light into a conventional headlamp beam. The beam isn't coherent or point-sourced, so it won't produce the 'speckling' interference effects of direct laser illumination, and it won't pose specular-reflection hazards. It's just a very bright and very well-controlled beam of normal white light.

Comment Re:Ah....and please tell me what your definition o (Score 1) 188

A projection is.

In my definition, it is "if I have x, y, z, and it continues on path q, I can project that it will continue to do so with a given accuracy". But as soon as I open my big fat mouth and say that "q will be such", I've changed from a projection of a model to a prediction. And when ALL of those predictions are wrong and revised.

That's where I think you're mistaken; they don't say, "q will be such", they state something more like, "if q continues to be such, we expect ___ with an X% level of confidence" (ya know, like scientists tend to do).

I found this IPCC glossary:

Climate prediction

A climate prediction or climate forecast is the result of an attempt to produce a most likely description or estimate of the actual evolution of the climate in the future, e.g. at seasonal, interannual or long-term time scales. See also: Climate projection and Climate (change) scenario.

 

vs

Climate projection

A projection of the response of the climate system to emission or concentration scenarios of greenhouse gases and aerosols, or radiative forcing scenarios, often based upon simulations by climate models. Climate projections are distinguished from climate predictions in order to emphasise that climate projections depend upon the emission/concentration/ radiative forcing scenario used, which are based on assumptions, concerning, e.g., future socio-economic and technological developments, that may or may not be realised, and are therefore subject to substantial uncertainty.

Finally, the IPCC projections are criticized for being, if anything, too conservative in their projections. Time and time again they've said X in Y years and in Y - Z years X is seen to be having an effect. And when something stupid does come out (Himalayan glaciers melting in 30 years), they correct it. Ya know, like scientists do.

Also, don't confuse media headlines with IPCC projections, just like you can't expect to see realistic scenes of IT in movies.

And please, check out the link a few posts above that points to the Ars Technica story where the comp sci prof has a look at the models - he was impressed - they're pretty good. Or, "all models are wrong, some are useful" and climate models are useful.

Comment Re:Two standard deviations more (Score 1) 188

If climate models were accurate, their predictions would be accurate. All of the models have failed on their predictions. This means, they are inaccurate and are not accurately reflecting the real world model.

They don't make predictions, they make projections; if you can't get that right, you're worse than the climate models.

Similar to confusing weather with climate.

Newtonian physics doesn't make accurate predictions (at relativistic speeds, for example), but it's still accurate (enough) for models. Or was Isaac Newton a "physicist" instead of a physicist because he didn't cover all cases?

Have you seen climate models, or do you just deny the ones that you don't like due to your standard of "truthiness"?

Ars Technica covers climate models nicely: (see page 2)

Steve Easterbrook, a professor of computer science at the University of Toronto, has been studying climate models for several years. “I'd done a lot of research in the past studying the development of commercial and open source software systems, including four years with NASA studying the verification and validation processes used on their spacecraft flight control software,” he told Ars.

When Easterbrook started looking into the processes followed by climate modeling groups, he was surprised by what he found. “I expected to see a messy process, dominated by quick fixes and muddling through, as that's the typical practice in much small-scale scientific software. What I found instead was a community that takes very seriously the importance of rigorous testing, and which is already using most of the tools a modern software development company would use (version control, automated testing, bug tracking systems, a planned release cycle, etc.).”

“I was blown away by the testing process that every proposed change to the model has to go through,” Easterbrook wrote. “Basically, each change is set up like a scientific experiment, with a hypothesis describing the expected improvement in the simulation results. The old and new versions of the code are then treated as the two experimental conditions. They are run on the same simulations, and the results are compared in detail to see if the hypothesis was correct. Only after convincing each other that the change really does offer an improvement is it accepted into the model baseline.”
