Comment Wrong way to look at it (Score 1) 99

It is the wrong way to look at this issue. It is not about to "allow" something to a weapon, it is about the question if a human in charge, like a soldier or the like, being entitled to use weapons, is allowed to delegate a) the decision when to pull the trigger, and b) if the person is to be allowed to delegate the responsibility. As with any machine or weapon anyway, be it making "decisions" in an "intelligent" way, or in a "stupid" one like a big bomb just falling somewhere, where beyond hope there is little final influence of a human being what exactly it hits after being thrown of an airplane or the like.

Cooling the Planet With a Bubble Bath 219

cremeglace writes "A Harvard University physicist has come up with a new way to cool parts of the planet: pump vast swarms of tiny bubbles into the sea to increase its reflectivity and lower water temperatures. 'Since water covers most of the earth, don't dim the sun,' says the scientist, Russell Seitz, speaking from an international meeting on geoengineering research. 'Brighten the water.' From ScienceNOW: 'Computer simulations show that tiny bubbles could have a profound cooling effect. Using a model that simulates how light, water, and air interact, Seitz found that microbubbles could double the reflectivity of water at a concentration of only one part per million by volume. When Seitz plugged that data into a climate model, he found that the microbubble strategy could cool the planet by up to 3C. He has submitted a paper on the concept he calls “Bright Water" to the journal Climatic Change.'"

Submission + - The perfect way to slice a pizza (newscientist.com)

iamapizza writes: New Scientist reports on the quest of two math boffins for the perfect way to slice a pizza. It's an interesting and in-depth article;

"The problem that bothered them was this. Suppose the harried waiter cuts the pizza off-centre, but with all the edge-to-edge cuts crossing at a single point, and with the same angle between adjacent cuts. The off-centre cuts mean the slices will not all be the same size, so if two people take turns to take neighbouring slices, will they get equal shares by the time they have gone right round the pizza — and if not, who will get more?"

This is useful, of course, if you're familiar with the concept of "sharing" a pizza.

Apple

Submission + - Respected developers begin fleeing from App Store 1

wiedzmin writes: Facebook's Joe Hewitt, Second Gear's Justin Williams, long-time Mac software developer known as "Rogue Amoeba" and other respected App Store developers have recently decided to discontinue their work on the platform, citing their frustration with Apple's opaque approval processes. Continued issues with erroneous and snap application and API rejections are prompting more and more developers to shun the platform entirely. Though there are tens of thousands of other developers pumping out over 100,000 iPhone apps, continued migration away from iPhone development will most likely result in less quality software for the platform.

Submission + - Vulgar Comment on Newspaper site costs man his job 1

DeeFresh writes: "ReadWriteWeb has an article up today discussing an incident in which a school employee lost his job after leaving a comment on the website of the St. Louis Post-Dispatch newspaper. After the school employee responded to the newspaper's poll of "the strangest thing you've ever eaten" with a feline-inspired vulgarity, Kurt Greenbaum, the site's director of social media, tracked down the commenter's identity through his IP Address and reported him to school officials. When confronted, the school employee resigned from his job.
Here is Greenbaum's follow up article discussing the employee's resignation."
Encryption

Submission + - US Government Using PS3s to Break Encryption (gamespot.com) 1

Entropy98 writes: As reported here and here.. It seems that the U.S. Immigration and Customs Enforcement Cyber Crimes Center, known as C3 have replaced their "$8,000 Tableau/Dell server combination" with more efficient and much cheaper $300 PS3s. Each PS3 is capable of 4 million passwords per second, and C3 currently has 20 PS3s with plans to buy 40 more.

Naturally this is only being used to break encryption on computers seized with a warrant and suspected of harboring child pornography.

A New Way To Produce Hydrogen 204

Iddo Genuth writes "Scientists at Pennsylvania State University and Virginia Commonwealth University are producing hydrogen by exposing clusters of aluminum atoms to water. Rather than relying on the electronic properties of the aluminum, this new process depends on the geometric distribution of atoms within the clusters. It requires the presence of 'Lewis acids' and 'Lewis bases' in those atoms (water can act as either). Unlike most hydrogen production processes, this method can be used at room temperature and doesn't require the application of heat or electricity to work. The researchers experimented with a variety of different aluminum cluster patterns, discovering three that result in hydrogen production."
