Five Ideas That Will Reinvent Computing 283
prostoalex writes "PC Magazine looks at 5 ideas that will reinvent computing. IMAX-quality movies at home with new projectors, a mid-air mouse that requires no flat surface, a home quantum computer, a router-based peer-to-peer system, and a man-made brain all made the list."

IMAX at Home
=============
You thought LAN parties were fun? Get ready for the projector party. At HP Labs, Nelson Chang and Niranjan Damera-Venkata have spent the past few years developing a technology that reinvents the notion of a home theater. With Pluribus, you can build a cineplex-quality image using a handful of ordinary, $1,000 PC projectors--in less time than it takes to pop the popcorn.
The Midair Mouse
================
Your brand-new wireless mouse? That solves only half the problem. Sure, you're untethered, free to drive your PC from afar. But you still need a flat surface. You may be camped out on the couch or curled up in bed, but you're never more than half an arm's length from an end table or a lap desk.
Soap goes one step further: It works in midair. With this new-age pointing device, now under development at Microsoft Research, you can navigate your PC using nothing but a bare hand. You can lose the end table and the lap desk. You can even lose the couch and the bed, driving your machine while walking across the room. It's a bit like the Wii remote--only more accurate and far easier to use.
Extreme Peer-to-Peer
====================
In 1543, Nicolas Copernicus forever changed the way we view the cosmos. He put the Sun at the center of things--not the Earth. Today, at the famed Palo Alto Research Center, Van Jacobson hopes to lead a similar revolution, one that forever changes the way we view PC networking. He aims to put the data at the center of things--not the server.
With a project called Content-Centric Networking, or CCN, Jacobson and his team of PARC networking gurus are turning this model on its head. They're building a networking system that revolves around the data itself, a system in which a router can actually identify that Bode Miller video and act accordingly. Under the CCN model, you don't tell the network that you're interested in connecting to a server. You tell it that you want a particular piece of data. You broadcast a request to all the machines on the network, and if one of them has what you're looking for, it responds.
The Man-Made Brain
==================
It could be the most ambitious computer science project of all time. At IBM's Almaden Research Center, just south of South Francisco, Dharmendra Modha and his team are chasing the holy grail of artificial intelligence. They aren't looking for ways of mimicking the human brain, they're looking to build one--neuron by neuron, synapse by synapse.
"We're trying to take the entire range of qualitative neuroscientific data and integrate it into a single unified computing platform," says Modha. "The idea is to re-create the 'wetware' brain using hardware and software."
Their first goal is to build a "massively parallel cortical simulator" that re-creates the brain of a mouse, an organ 3,500 times less complex than a human brain (if you count each individual neuron and synapse). But even this is an undertaking of epic proportions. A mouse brain houses over 16 million neurons, with more than 128 billion synapses running between them. Even a partial simulation stretches the boundaries of modern hardware. No, we don't mean desktop hardware. We're talkin' supercomputers.
So far, the team has been able to fashion a kind of digital mouse brain that needs about 6 seconds to simulate 1 second of real thinking time.

Do you even know how the Soap pointing device works? Hint: you don't wave it around in mid air. It's essentially the guts of an optical mouse put into a smooth, clear container and stuck into a sock. The optical sensor tracks the grain of the enclosing sock, and you manipulate it by squeezing the sock gently, causing the "mouse" inside to rotate - much as if you were squeezing a bar of soap (hence the name)
Unlike a lot of stuff coming out of Microsoft, I regard this little invention to be actually rather creative and worthwhile. If anything, it will definitely be a boon to people who need to use a pointing device during presentations (much better than the trackball solution we have today)

Quick... someone send a memo to Microsoft to let them know someone did this years ago. Nip over to your local computer shop and pick up a Gyration Ultra GT [extremetech.com]. Only problem is that your arms feel knackered after about 5 minutes of use. Pointless.

Good overview http://www.parc.com/research/projects/networking/
Also Van Jacobson, the man behind the project http://en.wikipedia.org/wiki/Van_Jacobson [wikipedia.org] was responsible, in part, for traceroute and other goodies, so there is probably quite a bit of traction there.

Microsoft "Soap" Mouse Hardly Innovative (Score:4, Informative)
There is also a video on YouTube (search for soap mouse" on how to make and use one. It's basically just a mouse in a sock.
And PC Magazine... what can I say? I haven't been there in a while and was amazed at all the crap on their web pages. One little block of text and the rest of the page is nothing but ad links. Very sad.

Non-Volatile RAM - not necessarily good (Score:2, Informative)
Early computers used non-volatile magnetic memory[1] in the place of RAM, which was really great in some cases. The memory was persistent, so if you lost power, the machine could pick up right where it left off, it was fairly resistant to radiation and/or EMPs, etc. However, if something went wrong in the program (esp. infinite loops), you had to stop the machine, physically remove the memory core (Typically on some kind of heavy drum in those days) and put it in another machine to overwrite the bad code. RAM was designed to be volatile precisely because the odds of some program going nuts (especially in a consumer device) and hosing the machine are relatively high. When that happens, the user needs to be able to recover control of the machine without requiring the use of another device to wipe the non-volatile memory and replace it.
While non-volatile RAM as persistent storage may prove an *excellent* replacement for our slow ferrous-oxide-based hard drives, I'd be very cautious about replacing our good ol' volatile "working-space" RAM just to take advantage of increased boot speed.
