Because plastic is lame

Love tip 3.. thats why I am at the ACT of course :) 3. Surround yourself with pros Surround yourself with people who are self-assured, and live life without comprising their core values. These people will rub off on you quickly. finally.. The world is already full of people who obey the status quo. But the people who don't give a fuck are the ones that change the world.

Lasers + diamonds --> simulate pressure of thousands of atmospheres on planetary cores!

As a side note, this is also being used as method to create a hypothetical substance called 'metallic hydrogen'. At such high pressures, hydrogen itself should become superconducting at room temperature and thus of tremendous interest...

Australian scientists have cleared one of the final hurdles for designing and building a quantum computer. The team of engineers from the University of New South Wales has successfully built a core component needed for the computer to operate and the work is published today in the journal Nature.

"After decades spent thinking, arguing, hoping, and in the words of Turyshev, "making a career off of it," these scientists' interest in the Pioneer anomaly has, understandably, accumulated psychological baggage; in the case of many of them, a cloud of emotional investment has formed around the core of objective scientific inquiry. And clouds obscure things."

165 pages about it!! http://arxiv.org/abs/1001.3686

good old Turyshev ...

Francesco pointed out this research one year ago, we dropped it as noone was really considering it ... but in space a low CPU power consumption is crucial!! Maybe we should look back into this?

I don't remember what is the speed factor, but I guess this might do it! Although, I remember when using an IMU that you cannot have the data above a given rate (e.g. 20Hz even though the ADC samples the sensor at a little faster rate), so somehow it is not just the CPU that must be re-thought. When I say qualification I also imply the "hardened" phase.

I don't know if the (promised) one-order-of-magnitude improvements in power efficiency and performance are enough to justify looking into this. For once, it is not clear to me what embracing this technology would mean from an engineering point of view: does this technology need an entirely new software/hardware stack? If that were the case, in my opinion any potential benefit would be nullified. Also, is it realistic to build an entire self-sufficient chip on this technology? While the precision of floating point computations may be degraded and still be useful, how does all this play with integer arithmetic? Keep in mind that, e.g., in the Linux kernel code floating-point calculations are not even allowed/available... It is probably possible to integrate an "accelerated" low-accuracy floating-point unit together with a traditional CPU, but then again you have more implementation overhead creeping in. Finally, recent processors by Intel (e.g., the Atom) and especially ARM boast really low power-consumption levels, at the same time offering performance-boosting features such as multi-core and vectorization capabilities. Don't such efforts have more potential, if anything because of economical/industrial inertia?

DARPA in search for orbit debris removal ideas

did you try it, Luca?? a simple way to make 3D effects with your wii.....amazing

The end of BOINC, DiGMO, P2P, etc... for massive computation

Big news for developers out there: Google has just announced the release of a new, open sourced programming language called Go. The company ...

Having Google backing it will certainly help, even though they are presenting it as a "system level" (i.e., hard-core) language, and in that domain it is much more difficult to bullshit your way to a position of relevance. Look at Java: Sun pushed it like hell and it is certainly widely used in many contexts (corporate, web and embedded markets mostly), yet it completely failed to win the hearts of "open-source" developers (or, more generally, of those developers who are not forced to use it by virtue of some management-driven decision).

"or, more generally, of those developers who are not forced to use it by virtue of some management-driven decision" completely agree with that!!

An unusual signal picked up by a European space observatory could be the first direct detection of dark matter particles, astronomers say. The findings are tentative and could take several years to check, but if confirmed they would represent a dramatic advance in scientists' understanding of the universe.

"A new Angry Birds-style game is set to help launch a new understanding of quantum science. Some find the concepts of quantum science confusing or unintuitive. Einstein even called quantum effects "spooky." To help people better understand some of the core concepts of quantum science, the Institute for Quantum Computing (IQC) at the University of Waterloo is launching a game - the Quantum Cats" Looking forward to see the ACT winning the Quantum Cats competition :)

"The Neuromorphic Computing Platform allows neuroscientists and engineers to perform experiments with configurable neuromorphic computing systems. The platform provides two complementary, large-scale neuromorphic systems built in custom hardware at locations in Heidelberg, Germany (the "BrainScaleS" system, also known as the "physical model" or PM system) and Manchester, United Kingdom (the "SpiNNaker" system, also known as the "many core" or MC system)."
