It looks like taking a sick day may get a lot harder. A UC San Diego research team says computer programs can tell the difference between genuine pain and fake pain a lot better than human beings:

Via Medical News Today:

They note that in social species like humans, faces have evolved to show valuable information in social contexts, and this includes expressions of emotions and pain.

However, “humans can simulate facial expressions and fake emotions well enough to deceive most observers,” says Prof. Kang Lee, senior author from the University of Toronto.

According to the study, there are two motor pathways in the brain that control facial movement:

  • Subcortical extrapyramidal motor system – which drives spontaneous facial expressions of felt emotions
  • Cortical pyramidal motor system – which controls voluntary (faked) facial expressions.

While humans are unable to consistently spot the subtle differences between the two, the team says a computer can.

Viewing The World Through The Lens Of Artificial Idiocy

road_testVia the Guardian Tom Chatfield on gazing at reality through computers’ data-crunching models:

When Facebook asks me what I “like”, it’s making the convenient assumption that I feel one of two ways about everything in the world – indifferent or affectionate. When it aggregates the results of mine and a billion other responses, marvellous insights emerge. But these remain based on a model of preference that might kindly be called moronic.

Similarly, every measurement embodies a series of choices: what to include, what to exclude. If a computer could learn to recognise images of cats with absolute accuracy, would that mean it knew what a cat was? Not unless you redefined cats as silent, immobile, odourless sequences of information describing two-dimensional images. If a computer could learn to identify you with absolute accuracy via surreptitiously scraped data from your social media presence, phone calls and banking activities, would that mean it knew what it means to be you?

Inside China’s Internet Addiction Rehab Camps

internet addictionThe New York Times has a short film exploring life inside one of China’s hundreds of boot-camp-style treatment centers for electronics-addled youth who spend night and day gaming online, in some cases allegedly wearing diapers to avoid taking bathroom breaks. The camp director compares the internet to “electronic heroin” and warns that the teens “know the internet inside and out, but nothing about human beings.”

Questions abound: Is China at the forefront of what will become a global epidemic of Compulsive Internet Use? Are computers being scapegoated for problems that are in fact more subtle and complex? Could you survive several months cold turkey?

The Closing of the Scientific Mind

Yale Professor of Computer Science David Gelernter thinks that science as become an “international bully”. You may recall that Gelernter was severely injured after receiving a mail bomb from Ted Kaczynski. Wonder what an open dialogue between these two would have been like had Kaczynski chosen a more peaceable tactic for his activism?*

Via Commentary:

The huge cultural authority science has acquired over the past century imposes large duties on every scientist. Scientists have acquired the power to impress and intimidate every time they open their mouths, and it is their responsibility to keep this power in mind no matter what they say or do. Too many have forgotten their obligation to approach with due respect the scholarly, artistic, religious, humanistic work that has always been mankind’s main spiritual support. Scientists are (on average) no more likely to understand this work than the man in the street is to understand quantum physics.

NSA Trying To Build Quantum Computer That Could Break All Forms Of Encryption

quantum computingTrying to maintain your privacy? Consider just giving up. The Washington Post reports:

In room-size metal boxes ­secure against electromagnetic leaks, the National Security Agency is racing to build a computer that could break nearly every kind of encryption used to protect banking, medical, business and government records around the world.

According to documents provided by former NSA contractor Edward Snowden, the effort to build “a cryptologically useful quantum computer” — a machine exponentially faster than classical computers — is part of a $79.7 million research program titled “Penetrating Hard Targets.” Much of the work is hosted under classified contracts at a laboratory in College Park, Md.

The development of a quantum computer has long been a goal of many in the scientific community. With such technology, all current forms of public key encryption would be broken, including those used on many secure Web sites as well as the type used to protect state secrets.

Computers Can Be Hacked Using High-Pitched Sound That You Can’t Hear

800px-Sine_waves_different_frequencies.svgGetting pissed off and screaming at your computer still shown to have no effect.

Via Scientific American:

Using the microphones and speakers that come standard in many of today’s laptop computers and mobile devices, hackers can secretly transmit and receive data using high-frequency audio signals that are mostly inaudible to human ears, a new study shows.

Michael Hanspach and Michael Goetz, researchers at Germany’s Fraunhofer Institute for Communication, Information Processing, and Ergonomics, recently performed a proof-of-concept experiment that showed that “covert acoustical networking,” a technique which had been hypothesized but considered improbable by most experts, is indeed possible.

An Atlas Of The Worlds Of Cyberspace

Maps of the physical world are obsolete. The vintage web page Atlas of Cyberspaces offers a strange and wonderful collection of nineties-era renderings of digital geographies – including physical infrastructure, virtual gaming realms, website and surfing structures, flows of communication, and more:

This is an atlas of maps and graphic representations of the geographies of the new electronic territories of the Internet, the World-Wide Web and other emerging Cyberspaces.

These maps of Cyberspaces – cybermaps – help us visualise and comprehend the new digital landscapes beyond our computer screen, in the wires of the global communications networks and vast online information resources.

Some of the maps you will see in the Atlas of Cyberspaces will appear familiar, using the cartographic conventions of real-world maps, however, many of the maps are much more abstract representations of electronic spaces, using new metrics and grids.

Pollution Makes Computers Sick, Too

Mike Rogoway writes at OregonLive:

The symptoms of industrial pollution are everywhere in Asia, where pedestrians wear surgical masks to filter the air and urban smog is sometimes so thick that Beijing’s Forbidden City is rendered nearly invisible behind a cloak of soot. Just this month, Chinese authorities canceled flights at Beijing’s main airport amid especially heavy pollution, and shuttered highways in and out of the city.

The implications for human health are obvious; studies show that pollution is shortening lifespans in northern China by five years or more.

Intel engineers in Oregon are now discovering that rotten air is also taking a toll on electronics in China and India, with sulfur corroding the copper circuitry that provides neural networks for PCs and servers and wrecking the motherboards that run whole systems.

“We got the board and it was pretty obvious. You open the chassis up and you see blackish material on every type of surface,” said Anil Kurella, the Hillsboro material scientist who’s leading Intel’s research effort.

The Stuxnet Computer Virus Has Infected The International Space Station

space_stationWell, we’ve even ruined outer space. io9 writes:

The problem with creating Stuxnet, the world’s most sophisticated malware worm, is that it could eventually go rogue. Which is precisely what has happened. The virus has spread to a Russian nuclear plant — and even the International Space Station.

Stuxnet is an incredibly powerful computer worm that was created by the United States and Israel to attack Iran’s nuclear facilities. It initially spreads through Microsoft Windows and targets Siemens industrial control systems. It’s considered the first malware that both spies and subverts industrial systems. It’s even got a programmable logic controller rootkit for the automation of electromechanical processes.

Let that last point sink in for just a second. This thing, with a little bit of coaxing, can actually control the operation of machines and computers it infects.

Apparently, the virus spread to the International Space Station on an infected USB stick that was transported by Russian cosmonauts.

Can We Make the Hardware Necessary for Artificial Intelligence?

Eye_iris“Logic is an organized way of going wrong with confidence” Robert Heinlein

This is my opinion of what might be, not What THE FUTURE!!! Will Be!

My POV is hardware driven, I do electronic design. I don’t present myself as “an authority” on Artificial Intelligence, much less “an authority” on sentient artificial intelligence, until they are Real Things, there is no such thing as an authority in that field. That said, if the hardware doesn’t exist to support sentient AI, doesn’t matter how wonderful the software is.

The following is why I’ve been saying in a number of places that I expect hardware to be able to run a synthetic consciousness in ~20 yrs, @2045singularity on Twitter asked me to clarify what I meant.

1. I assume that if the physical operations of a human brain can be simulated in real-time, programs that simulate human consciousness in real time can be part of that simulation.
