How Computational Complexity Will Revolutionize Philosophy

From Technology Review

For those of you who have been in my Data Structures and Algorithms class... or anyone who is interested in what can be accomplished "before the heat death of the universe." :-)

"The theory of computation has had a profound influence on philosophical thinking. But computational complexity theory is about to have an even bigger effect, argues one computer scientist."
"Since the 1930s, the theory of computation has profoundly influenced philosophical thinking about topics such as the theory of the mind, the nature of mathematical knowledge and the prospect of machine intelligence. In fact, it's hard to think of an idea that has had a bigger impact on philosophy."
"And yet there is an even bigger philosophical revolution waiting in the wings. The theory of computing is a philosophical minnow compared to the potential of another theory that is currently dominating thinking about computation."


Data are traveling by light

From Fraunhofer-Gesellschaft

My favorite part of the article: the use of the word "ensconced." A visible light WLAN might be kind of impressive, but if the users are also ENSCONCED in a room, well then that's just amazing!

Joking aside, this is an interesting approach to networking that doesn't rely on traditional radio signals.
"Just imagine the following scenario: four people are comfortably ensconced in a room. Each one of them can watch a film from the Internet on his or her laptop, in HD quality. This is made possible thanks to optical WLAN. Light from the LEDs in the overhead lights serves as the transfer medium."

5D glass storage could revolutionize medical imaging, computing

From ExtremeTech
"Researchers from the University of Southampton, England, have successfully recorded, read, and erased data from a piece of nano-structured glass. This technique could revolutionize microscopy in general, and medical imaging in specific — and, perhaps more importantly for computing, it could also be used to store binary data, like an optical disc."
"The end result, and it’s hard to say this with a straight face, is permanent five-dimensional data storage. Not only can the standard three dimensions be used — vertical and horizontal position on the piece of glass, and varying depth depending on the duration of the femtosecond laser pulse — but the wavelength and polarization of the light can also carry data. These nano-structures are absolutely tiny, too — just a few nanometers, much smaller than a DVD or Blu-ray disc — so we could be talking about an incredibly high-density storage medium."

How 5 Recent Social Uprisings Were Wired

From Scientific American


Iran, Tunisia, Egypt, China -- modern day revolutions are relying on wired technologies.
"From the horseback ride of Paul Revere—and for millennia before—people have used the latest technology available to rally others sympathetic to their cause. As ubiquitous as Twitter and Facebook have seemed lately in spreading the word for gatherings, whether benevolent or malevolent, many recent demonstrations and revolts have used a variety of primarily digital platforms to spread their message. Here are five examples in just the past two years:"

Apple's back-to-school promo clobbering Microsoft's efforts

Apple isn't just for artists anymore!
"Global Equities Research analyst Trip Chowdhry issued a note to investors earlier this week pointing out that education sales of Apple’s Macs have been significantly outselling Windows PCs. The firm’s research indicated that “80% of incoming students are buying Apple Computers vs. Windows Computers.”"

Chowdrhy also reports that Apple is enjoying substantial success in the Enterprise. New data indicates that “probably about 35% of Fortune 500 companies are giving Apple as a Choice to its employees, and majority are preferring Apple over Windows.”

The report believes that Apple's gains are a result of “the success of iPad is putting pressure on Enterprise IT to not only support iPad, but also Apple iPhones and Apple iMacs and MacBooks,” going as far as to say that high-level executives are “influencing the IT to bring Apple products into the Enterprise.”

This video shows some cool possibilities for near future tech. It's more than five minutes long, but engaging and worth it.



'Software is the Modern Language of Science'

From HPCwire

Computation, according to Nobel physics laureate Ken Wilson, has joined theory and experimentation as a "third leg" of scientific discovery (see Denning 2007, for example).

“We now have very small periods in time that are leading to very large changes in the amount of data, the amount of computation, and the amount of knowledge that is needed in order to carry out this kind of work,”
“...after more than four centuries of science being conducted at a painstakingly slow pace, today’s communications technologies and scientific advances are forcing a dramatic change–and acceleration–in all areas of science. At the heart of this change will be software.”
More recently, some have even been talking of a "fourth paradigm" -- the use of massive databases to discover new knowledge. For more see "The Fourth Paradigm," a series of essays published by Microsoft Research.
