NASA Tests Flying Airbag 118

coondoggie writes "NASA is looking to reduce the deadly impact of helicopter crashes on their pilots and passengers with what the agency calls a high-tech honeycomb airbag known as a deployable energy absorber. So in order to test out its technology NASA dropped a small helicopter from a height of 35 feet to see whether its deployable energy absorber, made up of an expandable honeycomb cushion, could handle the stress. The test crash hit the ground at about 54MPH at a 33 degree angle, what NASA called a relatively severe helicopter crash."

There is an access road to each tower (dirt trail) that has to be considered, but otherwise you can farm right around them. They must be spaced apart, and there's no reason not to use the land in between as farm ground.

Depression May Provide Cognitive Advantages 512

Hugh Pickens writes "Paul W. Andrews and J. Anderson Thomson, Jr. argue in Scientific American that although depression is considered a mental disorder, depression may in fact be a mental adaptation which provides real benefits. This is not to say that depression is not a problem. Depressed people often have trouble performing everyday activities, they can't concentrate on their work, they tend to socially isolate themselves, they are lethargic, and they often lose the ability to take pleasure from such activities such as eating and sex. So what could be so useful about depression? 'Depressed people often think intensely about their problems,' write the authors. 'These thoughts are called ruminations; they are persistent and depressed people have difficulty thinking about anything else. Numerous studies have also shown that this thinking style is often highly analytical. They dwell on a complex problem, breaking it down into smaller components, which are considered one at a time.' Various studies have found that people in depressed mood states are better at solving social dilemmas and there is evidence that people who get more depressed while they are working on complex problems in an intelligence test tend to score higher on the test (PDF). 'When one considers all the evidence, depression seems less like a disorder where the brain is operating in a haphazard way, or malfunctioning. Instead, depression seems more like the vertebrate eye — an intricate, highly organized piece of machinery that performs a specific function.'"

I believe there are many in this community that are willing to spend $200 on a toy. If I were to purchase a new video card for ~$200 to play games on my computer, I would consider that a toy. All the current generation gaming consoles are also in that range or above. Some may not consider them toys, but I do.. and so does dictionary.com

Don't get my wrong, I love my TiVo box, but TiVo isn't prompt with keeping up with listings changes. I own 2 units and everytime my cable provider has added/removed or shuffled channels, I have to enter a ticket. It takes about a week after the ticket is entered for it to be updated.

So while I agree that this isn't going to eliminate confusion, I have no sympathy for any hardship bestowed on TiVo's update department.

We left Gateway 3 years ago. We felt this coming, and wanted to get out before our warranties were up. We got close.

We went to Dell for a year.. then they jacked up prices. We've been buying dc5750's for 2 years. Now are moving to dc5850's. The dc5750 has been pretty solid, so far HP has been good to us. It's been nice to have a model last so long.

The Great Microkernel Debate Continues 405

ficken writes "The great conversation about micro vs. monolithic kernel is still alive and well. Andy Tanenbaum weighs in with another article about the virtues of microkernels. From the article: 'Over the years there have been endless postings on forums such as Slashdot about how microkernels are slow, how microkernels are hard to program, how they aren't in use commercially, and a lot of other nonsense. Virtually all of these postings have come from people who don't have a clue what a microkernel is or what one can do. I think it would raise the level of discussion if people making such postings would first try a microkernel-based operating system and then make postings like "I tried an OS based on a microkernel and I observed X, Y, and Z first hand." Has a lot more credibility.'"

College Demands RIAA Pay Up For Wasting Its Time 261

An anonymous reader writes "We've already seen the University of Wisconsin tell the RIAA to go away, but the University of Nebaska has gone one step further: it's asking the RIAA to pay up for wasting its time with the silly demand to push students into paying up. The spokesperson for the University also notes that since they constantly rotate IP addresses and have no need to hang onto that information for very long, they simply cannot help the RIAA. They have no clue who was attached to which IP address at the time the RIAA is complaining about."

Store Says DRM Causes 3 of 4 Support Calls 155

Carter writes "Ars Technica is reporting that Musicload, one of Europe's largest movie stores, has found that 75% of its customer support problems are caused by DRM. Users have frequent problems using the music that they have purchased, which has led Musicload to try selling independent label music without DRM. Artists choosing to abandon DRM in favor of good old-fashioned MP3 have seen 40% growth in sales since December. Good to see someone in the business both 'gets it' and is willing to do something about it."

For AMD Success Means Problems 193

An anonymous reader writes "AMD's success with its dual-core Opteron and Athlon processors has created something of a happy problem for the company. It can't make its products fast enough to meet demand. Just the same, with the Intel price war heating up and new 65-nanometer manufacturing technology being implemented in its factories, AMD has a lot of balls in the air right now." From the News.com article: "AMD's current pickle is the result of its success, which makes it a little easier to swallow for company executives. Demand is high, but the company's dual-core processors still use its 90-nanometer manufacturing technology. Intel's chips, on the other hand, are built using the smaller transistors provided by its 65-nanometer manufacturing technology. Not only is AMD using larger transistors, but its dual-core Opteron and Athlon 64 processors contain two processing cores integrated onto a single piece of silicon, or a die. This design has given AMD great performance during the past few years, but resulted in processors that were almost twice the size of its single-core chips."
