Monkeys Exhibit the Same Economic Irrationality As Us 254

grrlscientist writes "Laurie Santos is trying to find the roots of human irrationality by watching the way our primates make decisions. This video documents a clever series of experiments in 'monkeynomics' and shows that some of the stupid decisions we make are made by our primate relatives too."

Churchill Accused of Sealing UFO Files, Fearing Public Panic 615

Newly released secret files show that Winston Churchill ordered a cover-up of an alleged encounter between a UFO and a RAF bomber because he feared public panic. From the article: "Mr Churchill is reported to have made a declaration to the effect of the following: 'This event should be immediately classified since it would create mass panic among the general population and destroy one's belief in the Church.'"

Dinosaur Feather Color Discovered 219

anzha writes "Do you remember being a kid and told we'd never know what colors the dinosaurs were? For at least some, that's no longer true. Scientists working in the UK and China have closely examined the fossils of multiple theropods and actually found the colors and patterns that were present in the fossilized proto-feathers. So far, the answer is orange, black and white in banded and other patterns. The work also thoroughly thrashes the idea that fossils might not be feathers, but collagen fibers instead. If this holds up, Birds Are Dinosaurs. Period. And colorful!"

The rule of Perceptual Entropy is that you need a minimum bitrate of 176kbps for 44.1kHz stereo. If you're encoding below that, it can't possibly be indistinguishable from the original. ITU-R BS.1116-1 testing has proven that simple fact out over and over again.

How can this be true? If you record a 22kHz square wave, you certainly don't need 176kbps to describe that as perfectly as uncompressed audio - it depends how good your compression algorithm is.

I'm not disagreeing with your other points, but subjective testing is never that simple.

Submission + - Death Knell for DoS Extortion?

Ron writes: "An Infoworld article reports that Yazan Gable, a security researcher, has put forward an explanation as to why the numbers of denial of service attacks have been declining. His theory is that DoS attacks are no longer profitable to attackers. While spam and phishing attacks directly generate profit, he argues that extortion techniques often used with DoS attacks are far more risky and often make an attacker no profit at all. He writes:

So what happens if the target of the attack refuses to pay? The DoS extortionist is obligated to carry out a prolonged DoS attack against them to follow through on their threats. For a DoS extortionist, this is the worst scenario because they have to risk their bot network for nothing at all. Since the target has refused to pay, it is likely that they will never pay. As a consequence, the attacker has to spend time and resources on a lost cause.
