Wearable projector augments your reality and makes every surface an interface

This one’s doing the rounds everywhere, and with some justification. I try to steer away from pure OMG TECH! posts here at Futurismic, but if this doesn’t kick you right in the cyberpunk-sensawunda gland with a big pair of hob-nailed boots… well, you’re obviously not as massive an unreconstructed nerd as I am, basically.

See what I mean? As I remarked to a fried on Twitter last night, I’ll cheerfully trade my mortal soul to the first cellphone provider that offers me something that can do all that. Awesome. [via Hack-a-Day and many others]

Bay of Pigs to Bay of Penguins – the Cuban Linux fork

LOLcastroRemember we mentioned late last year that Cuba was talking about going open-source to guarantee their technological independence from the United States (and presumably everyone else as well)?

Well, it seems that Cuba has not only adopted Linux but started developing its own independent distribution:

Nova is Cuba’s own configuration of Linux and bundles various applications of the operating system.

Rodriguez said several government ministries and the Cuban university system have made the switch to Linux but there has been resistance from government companies concerned about its compatibility with their specialized applications.

“I would like to think that in five years our country will have more than 50 percent migrated (to Linux),” he said.

Unlike Microsoft, Linux is free and has open access that allows users to modify its code to fit their needs.

“Private software can have black holes and malicious codes that one doesn’t know about,” Rodriguez said. “That doesn’t happen with free software.”

As TechDirt points out, that last comment isn’t really true at all; whether it was included out of ignorance or for propaganda purposes will presumably remain a mystery.

I wonder if they’ll open up the repositories to non-Cuban users? It’s another great propaganda angle – stuffing the man pages with little homilies on object-orientated Communism from Castro and Guevara… [via SlashDot image by factor_]

Recycling waste heat in computers to increase efficiency

computer processor pinsThe ever-louder whining of my computer’s processor fan is a constant reminder that there’s a lot of energy wasted in modern microprocessors (and that it’s high time I replaced the ageing beast for a machine less likely to collapse at any moment).

While we’re unlikely to be offered room-temperature computer systems any time soon, engineers in the emerging field of phononics are looking at ways to harvest that waste heat and make computers more efficient in the process:

It exploits the fact that some materials can only exchange heat when they are at similar temperatures. The small memory store at the heart of their design is set to either a 1 or 0 temperature by an element that can rapidly shunt in or draw out heat. The store itself is sandwiched between two large chunks of other materials.

One of those materials is constantly hot, but can only donate heat to the memory store when that too is hot, in the 1 state. The material on the other side of the memory patch is always kept cold, but can draw heat away from the store whatever state it is in.

Early days yet, of course, but maybe thermal computing will give Moore’s Law another stay of execution when we reach the practical limits of circuit integration. [via SlashDot; image by Ioan Sameli]

Living la vida geo-loca

iPhone geo-locational software screenshotOver at Wired last week, they ran a piece by Matthew Honan about his experiences with the new wave of geolocational software for the iPhone and Google’s G1. He starts off by asking fellow users in his locality what they use the systems for:

My first response came from someone named Bridget, who, according to her profile, at least, was a 25 year-old woman with a proclivity for scarves. “To find sex, asshole,” she wrote.

“I’m sorry? You mean it’s for finding people to have sex with?” I zapped back.

“Yes, I use it for that,” she wrote. “It’s my birthday,” she added.

“Happy birthday,” I offered.

“Send me a nude pic for my birthday,” she replied.

A friendly offer, but I demurred. Anonymous geoshagging is not what I had in mind when I imagined what the GPS revolution could mean to me.

I don’t think anyone who has looked at the adoption curve for new networking technology will be particularly surprised by Bridget’s response… [image by zanaca]

Honan goes on to look at the pros and cons of what is admittedly still a technology in its applicational infancy, which he finds fun and intriguing at the same time that it seems creepy and intrusive – the latter response being one that I’d attribute to his age. When these apps have matured in a few years, however, the Facebook generation will have no qualms or fears about them whatsoever.

Whether they should have qualms is another question, of course. If nothing else, geolocational apps are a reminder that the tin-foil hat brigade’s warnings about The Feds being able to follow your cell phone weren’t entirely fictional; the potential for stalking someone is obvious.

But would stalking be as big a risk in a society where many people’s locations were public knowledge? If lifelogging catches on at the same time, we might all become one big happy globally geolocative panopticon…

‘Ghost’ Photos through Quantum Physics

toysoldierScientists funded by the Air Force have used quantum entanglement — in which pairs of particles continue to interact even after they are spatially separated — to snap this picture of a tin solider without aiming a camera directly at the object.  The technique, called “ghost imaging,” has potential military or space applications, such as using aerial drones to survey of battlefields obscured by clouds, or the smoke that follows airstrikes.  Yanhua Shih, who has been experimenting with entangled photons since 1995, says:

“…[T]he image is not formed from light that hits the object and bounces back. The camera collects photons from the light sources that did not hit the object, but are paired through a quantum effect with others that did. An image of the toy begins to appear after approximately a thousand pairs of photons are recorded.”

These are exciting times on the frontiers of physics. Researchers in Copenhagen took a step towards producing a quantum bit. And scientists at Arizona State are trying to figure out how electrons interact. Both are necessary steps towards building superfast quantum computers.
