Visual Hallucinations Are a Normal Grief Reaction 550

Hugh Pickens writes "Vaughn Bell has written an interesting essay at Scientific American about grief hallucinations. This phenomenon is a normal reaction to bereavement that is rarely discussed, although researchers now know that hallucinations are more likely during times of stress. Mourning seems to be a time when hallucinations are particularly common, to the point where feeling the presence of the deceased is the norm rather than the exception. A study by Agneta Grimby at the University of Goteborg found that over 80 percent of elderly people experience hallucinations associated with their dead partner one month after bereavement, as if their perception had yet to catch up with the knowledge of their beloved's passing. It's not unusual for people who have lost a partner to clearly see or hear the person about the house, and sometimes even converse with them at length. 'Despite the fact that hallucinations are one of the most common reactions to loss, they have barely been investigated and we know little more about them. Like sorrow itself, we seem a little uncomfortable with it, unwilling to broach the subject,' writes Bell. 'We often fall back on the cultural catch all of the "ghost" while the reality is, in many ways, more profound.' "

Programming .NET 3.5 Screenshot-sm 224

lamaditx writes "The world of the .NET framework is taken to the next level by the release of .NET 3.5. The intended audience of this book are experienced .NET programmers. There are no sections that tell you details about C#, SQL servers or anything like that. I don't recommend this book if you never worked on a .NET project and don't know how to set up a SQL database. You should be aware that the code is written in C#. You might use one of the software code converters if you prefer Visual Basic instead. I think the code is still readable even if you do not know C#. I appreciate the fact that the authors decided to use one language only because it keeps the book smaller. The authors assume you are using Visual Studio 2008. You don't necessarily need to update to 2008 if you are working with an older edition because you can use the free Express Edition to get started." Keep reading for the rest of Adrian's review.

NASA Plans Probe to the Sun 352

FudRucker writes "For more than 400 years, astronomers have studied the sun from afar. Now NASA has decided to go there. 'We are going to visit a living, breathing star for the first time,' says program scientist Lika Guhathakurta of NASA Headquarters. 'This is an unexplored region of the solar system and the possibilities for discovery are off the charts.'"

Interconnecting Wind Farms To Smooth Power Production 112

Roland Piquepaille writes "Wind power is one of the world's fastest growing electric energy sources, but as wind is intermittent, a single wind farm cannot deliver a steady amount of energy. This is why scientists at Stanford University want to connect wind farms to develop a cheaper and more reliable power source. Interconnecting wind farms with a transmission grid should reduce the power swings caused by wind variability and provide a somewhat constant and reliable electric power (or 'baseload' power) provided by other power plants."

Comment Re:Wireless card??? WTF? (Score 2, Informative) 170

VMWare by default bridges your network interface into the VM. Wireless drivers have such poor support for network bridging that this almost never works. It especially doesn't work with WPA or any such.

If you NAT your VM network traffic, then things work (well sorta, with all the nastiness that NAT comes with).

A Hardware-Software Symbiosis 120

Roland Piquepaille writes "We all want smaller and faster computers. Of course, this increases the complexity of the work of computer designers. But now, computer scientists from the University of Virginia are coming with a radical new idea which may revolutionize computer design. They've developed Tortola, a virtual interface that enables hardware and software to communicate and to solve problems together. This approach can be applied to get a better performance from a specific system. It also can be used in the areas of security or power consumption. And it soon could be commercialized with the help of IBM and Intel."

Improving Noise Analysis with the Sound of Silence 54

Roland Piquepaille writes "Researchers at Rockefeller University have built a mathematical method and written an algorithm based on the way our ears process sound that provides a better way to analyze noise than current methods. Not only is their algorithm faster and more accurate than previous ones used in speech recognition or in seismic analysis, it's also based on a very non-intuitive fact: they know what a sound was by knowing when there was no sound. 'In other words, their pictures were being determined not by where there was volume, but where there was silence.' The researchers think that their algorithm can be used in many applications and that it will soon give computers the same acuity as human ears. Read more for additional references and pictures about this algorithm."

NASA's 20-G Centrifuge Machine 154

Roland Piquepaille writes "Scientists from NASA and two U.S. universities are using a 20-G centrifuge machine that can simulate up to 20 times the terrestrial gravity to evaluate the effects of hypergravity on humans. This 58-foot diameter centrifuge has three cabins, one for humans -- limited to 12.5 G -- and two for objects and flying hardware. The goal of these experiments is to reduce the adverse effects that space travel can have on astronauts' physical heath. But by studying the health benefits of exercise on astronauts, the researchers also hope to help the rapidly growing senior population who, like astronauts, doesn't exercise much.

McNealy Created Millions of Jobs? 363

cahiha writes "In his blog, Jonathan Schwartz argues that Scott McNealy is single-handedly responsible for making network computing a reality. His timeline is something like that in 1992, the industry was focused on 'Chicago' (Windows 95), while McNealy bravely went his own way-- 'the network is the computer.' He goes on to claim that 'There is no single individual who has created more jobs around the world than [Scott McNealy]. [...] I'm not talking hundreds or thousands of jobs, I'm talking millions.' I have trouble following his argument: client/server computing and distributed computing were already widely available and widely used in the early 1990s. The defining applications of the emerging Internet were, not Java, but Apache, Netscape, and Perl. Sun's biggest response to Chicago was to attempt to establish Java as the predominant desktop application delivery platform, something they have not succeeded at so far. So, what do you think: is Schwartz right in giving credit to McNealy for creating 'millions' of jobs? Or has Sun been a company on the decline since the mid-1990s, only temporarily buoyed by the Internet bubble?"

Run Windows Applications Natively in OS X? 521

mcho writes "Unlike other speculators, who get no spam, Robert X. Cringely offers an intriguing reason behind Apple's recent strategy of Boot Camp. From the article: 'I believe that Apple will offer Windows Vista as an option for those big customers who demand it, but I also believe that Apple will offer in OS X 10.5 the ability to run native Windows XP applications with no copy of XP installed on the machine at all. This will be accomplished not by using compatibility middleware like Wine, but rather by Apple implementing the Windows API directly in OS X 10.5.'
