Submission + - Linux for small organizations

Submitted by chris1646
chris1646 writes: Currently we are a small organization that is entirely a Windows shop. Next year much of the server and desktop hardware we run will need replacing. I am looking for creative ways to introduce Linux as my desktop and server OS of choice, however a couple of our core applications run exclusively on Windows. Has anyone had any success hosting Windows applications via terminal server while using Linux as the client OS? Has anyone handled a AD to open source LDAP migration?

Wireless Sensors To Monitor Power Grids 72

Posted by samzenpus from the nano-oversight dept.
Roland Piquepaille writes "Major power outages like the ones which affected the New York state last month or Western Europe ten days ago are becoming more frequent — even if their causes were different. In some cases, the utility companies have to dispatch electricians all over the place to discover the cause of the power failure or simply to restore power. Engineers at the University of Buffalo think they have a better solution: deploy wireless 'nanotech' sensors to monitor the networks and to find the exact location of a failure. They also say that even if the technology is almost available, several years of research are necessary before such a solution can be used by electrical companies. Read more for additional details about this attractive solution."

Robot Swarm Shifts Heavy Objects 142

Posted by Zonk from the robo-movers-sound-great dept.
holy_calamity writes "A swarm of robots has been demonstrated that can get together to transport an object too heavy for a single bot. Each robot is loaded with the same simple set of behaviors but more complex intelligence emerges from a group interacting. Two videos show the robots in action, and using a more complex behavior necessary when they're set to short sighted mode and can't see the target location from the starting point."

Thrust from Microwaves - The Relativity Drive 567

Posted by Zonk from the yay-for-science dept.
dfenstrate writes "The latest New Scientist has an article about an engine that exploits relativity and microwaves to generate thrust. There is a working prototype." From the article: "Roger Shawyer has developed an engine with no moving parts that he believes can replace rockets and make trains, planes and automobiles obsolete ... The device that has sparked their interest is an engine that generates thrust purely from electromagnetic radiation — microwaves to be precise — by exploiting the strange properties of relativity. It has no moving parts, and releases no exhaust or noxious emissions. Potentially, it could pack the punch of a rocket in a box the size of a suitcase. It could one day replace the engines on almost any spacecraft. More advanced versions might allow cars to lift from the ground and hover."

The Impact of Social Networking on Society 115

Posted by CmdrTaco from the jennifer-aniston-won't-be-my-friend dept.
Anonymous Pingu writes "The latest edition of New Scientist has a series of features on social networking. These include an analysis of the impact on our social attitudes by Sherry Turkle, a feature on the possible privacy implications of using sites like MySpace and Friendster, and a short science fiction piece by Bruce Sterling. It's certainly interesting that so many people post very revealing stuff about themselves on these sites."

The Nanopowers of Spinach 53

Posted by Zonk from the i-yam-what-i-yam-and-that's-all-that-i-yam dept.
Roland Piquepaille writes "Ohio University physicists have used a simple molecule of chlorophyll taken from spinach to develop a complex nanobiological switch. They used a scanning tunneling microscope (STM) to image chlorophyll-a and then injected it with a single electron to manipulate the molecule into four positions. The researchers say this biological switch might be used in future applications for green energy, technology and medicine. Read more for additional pictures and references about this spinach-based biological switch."

Steve Irwin Dead 1004

mkosmo writes "News.com.au is reporting that Steve Irwin was killed in a freak accident while filming one of his well known documentaries. Surprisingly it wasn't a crocodile, it was a sting-ray."

Pro MySQL 100

Posted by samzenpus from the read-all-about-it dept.
Rob Lanphier writes "I'm sure there are plenty of people like myself who do a fair amount of programming against MySQL databases, and consider it a feature of the product that it's pretty easy to do without having to fuss much with the actual database. Still, it's nice to look at what goes on under the hood, even if smoke isn't pouring out from beneath it. Pro MySQL by Michael Kruckenberg and Jay Pipes provides a broad well-organized exploration of intermediate and advanced MySQL topics that is a satisfying overview of the database management system."

Morphine Relief Without Addiction? 308

Posted by ScuttleMonkey from the plop-plop-fizz-fizz dept.
Roland Piquepaille writes "Morphine has been used as a painkiller for decades, if not centuries. Unfortunately for patients, morphine is also an addictive substance. Now, Brigham Young University (BYU) chemists are using a vine plant that grows in Australia to develop a new painkilling molecule, but with fewer side effects. The Deseret Morning News reports that the BYU chemists hope to ease pain with hasubanonine, the synthetic compound they created and which has a similar molecular structure as morphine. Still, more tests need to be done before this natural drug can replace morphine."

Another Robotic Vehicle to Help Soldiers 154

Posted by Zonk from the johnny-five-is-alive dept.
Roland Piquepaille writes "There are many teams of U.S. scientists working on robots able to find improvised explosive devices (IEDs) in Iraq before they can kill American soldiers. Today, let's look at an effort going on at Florida State University (FSU) to build unmanned ground vehicles that could save soldiers' lives. The researchers are creating complex algorithms to control these robots who will have to integrate many different factors such as the type of ground surface or obstacles that might block the vehicle's path. Some of these robots, which also could be used for civilian missions, are currently being tested at FSU. Read more for additional references and pictures of these robots which will have to navigate among dense obstacles."

Hydrogen Fuel Balls from a Gas Pump? 280

Posted by ScuttleMonkey from the quite-a-racket dept.
navalynt writes "New Scientist reports that the Department of Energy has filed a patent for hydrogen fuel balls. From the article 'The proposed glass microspheres would each be a few millionths of a metre (microns) wide with a hollow center containing specks of palladium. The walls of each sphere would also have pores just a few ten-billionths of a metre in diameter.' They are supposedly safe and small enough to be pumped into a fuel tank in the same manner as gasoline."

Biggest Obstacle of Nuclear Fusion Overcome? 444

Posted by Hemos from the baby-steps-to-clean-energy dept.
Yetihehe writes "Nuclear fusion could become a more viable energy solution with the discovery of way to prevent super-hot gases from causing damage within reactors. The potential solution, tested at an experimental reactor in San Diego, US, could make the next generation of fusion reactors more efficient, saving hundreds of millions of euros a year."

Day of the Robotic Tentacle 199

Posted by ScuttleMonkey from the of-course-they-will-do-a-sequel dept.
holy_calamity writes "New Scientist is reporting on a robotic tentacle developed thanks to funding from military agency DARPA. From the video it looks to have a lot of potential, I can almost feel it fastening around my ankle right now."

Lucent Sues Microsoft, Wants All 360s Recalled 475

Posted by CowboyNeal from the we-did-it-first dept.
robyannetta writes "Lucent has filed a lawsuit against Microsoft, demanding that they pull all Xbox 360s from the market. Lucent claims that Microsoft has violated their MPEG2 patents which they claim they patented in 1993." While it's unlikely console will be pulled from shelves, it's one way to generate some publicity.

3D Face Imaging in 40 Milliseconds 170

Posted by ScuttleMonkey from the whole-new-meaning-to-snapshot dept.
Roland Piquepaille writes "Computer scientists at Sheffield Hallam University, UK, have developed a new face recognition software which can produce an exact 3D image of a face within 40 milliseconds. A pattern of light is projected on your face, creating a 2D image, from which an accurate 3D representation is generated. This technology should speed airport check-ins, but it could also be used in banks or for checking ID cards as it allows full identification in less than one second."
