The Real Time Search Dilemma: Consciousness Versus Memory

"There is something about human nature which makes us want to prioritize information by how recent it is, and that is the fundamental appeal of real time search. The difference between real time search and regular search didn’t really crystallize for me until I had a conversation with Edo Segal, who sold his real time search company Relegence to AOL a few years ago and holds three patents on the subject. “Real time taps into consciousness,” says Segal, “search taps into memory. That is why it so potent. You experience the world in real time.”"

Disorderly genius: How chaos drives the brain - life - 29 June 2009 - New Scientist

: "HAVE you ever experienced that eerie feeling of a thought popping into your head as if from nowhere, with no clue as to why you had that particular idea at that particular time? You may think that such fleeting thoughts, however random they seem, must be the product of predictable and rational processes. After all, the brain cannot be random, can it? Surely it processes information using ordered, logical operations, like a powerful computer?

Actually, no. In reality, your brain operates on the edge of chaos. Though much of the time it runs in an orderly and stable way, every now and again it suddenly and unpredictably lurches into a blizzard of noise.

Neuroscientists have long suspected as much. Only recently, however, have they come up with proof that brains work this way. Now they are trying to work out why. Some believe that near-chaotic states may be crucial to memory, and could explain why some people are smarter than others."

Can Your Brain Fight Fatigue? - Well Blog - NYTimes.com

"The mental choreography of fatigue is intricate, involving messages sent not only from the brain to the straining muscles but also to various areas within the mind as well. Data from some recent brainwave studies of athletes showed that during long, hard exercise, there’s often a moment when portions of the brain become “de-aroused,” Foster says. “It’s similar to depression,” he adds, and plays out in motivation. You begin to wonder why in the world you’re running, swimming or pedaling so hard. You slow down."

Brain Stimulant: Virtual Fly Brain Computer Model

"Most people think about ways that they can get rid of insects. However, some scientists are actually considering what it would take to create artificial insects with virtual brain's. Researchers are now planning to create a computer simulation of a fly's brain (drosophila). Could this virtual fly brain enable military mad scientists to fine tune a bug's functioning? Perhaps you could recalibrate a bug's pleasure circuitry so it would find enjoyment in injecting deadly poison into enemy combatants. Or maybe this might allow the development of increasingly complex forms of insect behavior like swarming or intelligence gathering by precisely altering the bug's neural wetware (with the help of the model)."

Video: How to Build a High Traffic Blog | Tim Ferriss

"Over the last WordCamp San Francisco Tim Ferriss, author of The 4-Hour Workweek (name of both his book and blog), gave a presentation on “how to build a high traffic blog without killing yourself.”

It lasts 50 minutes, and he covers a wide range of topics, from posting frequency to blogging tools and community building. The cool thing is that most of the stuff is coming from the tests that Tim run over the years. Worth watching."
