Monkeys With Syntax 197

jamie writes "The Campbell's monkey has a vocabulary with at least six types of basic call, but new research published in the PNAS claims that they combine them and string them together to communicate new meanings. (Login may be required on the NY Times site.) For example, the word for 'leopard' gets an '-oo' suffix to mean 'unseen predator.' But when that word is repeated after 'come over here,' the combination means 'Timber!' — a warning of falling trees. Scientists have known for some time that vervet monkeys have different warning calls for different predators — eagle, leopard, and snake — but unlike the Campbell's monkeys, vervets don't combine those calls to create new meanings, a key component of syntax. The researchers plan to play back recordings to the monkeys to test their theories for syntax errors."

Over 160 Tutorial Videos Created For Unreal Dev Kit 48

As a follow-up to Epic Games' release of a free version of the Unreal Engine last month, the company has now posted over 160 video tutorials which demonstrate the various uses of the Unreal Development Kit. Roughly 20 hours of footage were created by technical education company 3D Buzz, with topics ranging from user interface to game physics to cinematics.

Ted Dziuba Says, "I Don't Code In My Free Time" 619

theodp writes "When he gets some free time away from his gigs at startup Milo and The Register, you won't catch Ted Dziuba doing any recreational programming. And he wouldn't want to work for a company that doesn't hire those who don't code in their spare time. 'You know what's more awesome than spending my Saturday afternoon learning Haskell by hacking away at a few Project Euler problems?' asks Dziuba. 'F***, ANYTHING.'"

Relativistic Navigation Needed For Solar Sails 185

KentuckyFC writes "Last year, physicists calculated that a solar sail about a kilometer across with a mass of 300 kg (including 150 kg of payload) would have a peak acceleration of roughly 0.6g if released about 0.1AU from the Sun, where the radiation pressure is highest. That kind of acceleration could take it to the heliopause — the boundary between the Solar System and interstellar space — in only 2.5 years; a distance of 200 AU. In 30 years, it could travel 2500AU, far enough to explore the Oort Cloud. But the team has discovered a problem. Ordinary Newtonian physics just doesn't cut it for the kind of navigational calculations needed for this journey. Because the sail has to be released so close to the Sun, it becomes subject to the effects of general relativity. And although the errors these introduce are small, they become magnified over the course of a long journey, sending the sail roughly 1 million kilometers off course by the time it reaches the Oort Cloud. What these guys are saying is that if ever such a sail is launched (and the earliest estimate is 2040), the navigators will have to be proficient in a new discipline of relativistic navigation."

Team Aims To Create Pure Evil AI Screenshot-sm 527

puroresu writes "Scientific American reports on the efforts of Selmer Bringsjord and his team at the Rensselaer Polytechnic Institute, who have been attempting to develop an AI possessed of an interesting character trait: pure evil. From the article, 'He and his research team began developing their computer representation of evil by posing a series of questions beginning with the basics: name, age, sex, etc., and progressing to inquiries about this fictional person's beliefs and motivations. This exercise resulted in "E," a computer character first created in 2005 to meet the criteria of Bringsjord's working definition of evil. Whereas the original E was simply a program designed to respond to questions in a manner consistent with Bringsjord's definition, the researchers have since given E a physical identity: It's a relatively young, white man with short black hair and dark stubble on his face.'"

Frankly, the mention of the term "carbon footprint" puts this squarely in the "hype" category.

Why did that get modded 5 insightful? Carbon Footprint is a valid and useful term.

The only reason I can see why some might like the above comment is if they are so conservative on climate change, they reject even the terms used in discussing it.

It would almost qualify as an example of the logical fallacy known as the "Appeal to Ridicule" but it wasn't quite intelligent enough.

BioShock Creator Levine Teases Next Project 34

simoniker writes "In a new interview, BioShock creator Ken Levine has been talking about his studio's philosophy and teasing, at least abstractly, his next project, of which he says 'we had a scope and ambition in mind which is more ambitious than anything we've ever done. Even more, substantially more ambitious than BioShock.' He also commented on 2K Marin, currently working on BioShock 2, wishing them luck but making it clear that he is not majorly involved in the game: 'I'm not working on BioShock 2. I make no claim to anything on BioShock 2, and I think it's important that that's their product, and their culture. Because you can't just clone a studio.'"

Ok.

So, we just cut the budget on this project from $4billion to $0.5billion.

And in the meantime, we also just gave $700billion to a bunch of banks. To save them from bankruptcy that was of their own making.

WTF !?!?!

Give NASA some funding - like maybe a tenth of what is being spent in fixing the financial crisis? At least then we know it will be spent on achieving something great.

Comment Re:I already have more than five senses (Score 1) 187

By going on about the lesser known senses beyond the commonly understand five, you have completely missed the point of this demo, which shows a very interesting new technology. You have focused on an entirely unrelated point about number of senses, purely because of the title of the demo. Whether we have 5 or 16 does not change in any way the coolness of this technology. Don't be so pedantic.

With that attitude, yet you're posting on Slashdot? If nerd culture means anything, it means abandoning any pressure on trying to "Get a Life" whatever that means. It means instead to do what you instinctively feel, matters. Embrace your nerdness. One of us, one of us ...

Comment The analogy is inapt (Score 2, Interesting) 209

The tribe analogy is inapt, because tribes didn't have distinctions like employer/employee, government/citizen, rich/poor. Currently within each of those pairs the surveillance levels are almost completely one-sided in favour of the former. There seems to be very little trend to address that imbalance, and the surveillance described in the article would increase it. If anything the balance should be more surveillance of the former, since those are the ones with more power, and as the great Stan Lee said, "With great power comes great responsibility". Sadly the former in each case wants to increase their power over the latter, and increased surveillance is just one of the tools.

Attempts to have disclosure of information from the former to the latter exist (eg google "freedom of information", "open government" or "corporate disclosue") but they are usually weak, because of the laziness of members of the latter.

China to Build a Zero-Carbon Green City 620

gormanw writes "Just outside Shanghai, there is an island about the size of Manhattan. China is going to build its first-ever 'green city', complete with no gasoline/diesel powered vehicles, 100% renewable energy, green roofs, and recycling everything. The city is called Dongtan and it should house about 5,000 people by the end of 2010, with estimates of 500,000 by 2050. The goal is to build a livable city that is energy efficient, non-polluting, and protects the wildlife in the area."
