A new NASA-sponsored study suggests that small lawnmower-sized robots could be used to build a landing site for a moon outpost. In order to be efficient a landing pad would have to be close to any structures created, but without an atmosphere to slow down the lunar sand it would sandblast the outpost, creating the need for some sort of protection. By using small robots to either build protective berms or collect rocks to "pave" a landing pad, NASA hopes to provide protection against the sand-blasting effects of a landing on the moon.

Engadget is reporting that a new "Touch Book" being previewed at DEMO '09 in California by the company "Always Innovating" promises a new take on mobile computing devices. Touting 10 to 15 hours of battery life, this ARM-powered netbook weighs less than two pounds, but the true magic comes with the detachable screen that can function as a completely stand-alone touchscreen tablet. The machine is currently running a Linux OS with a touchable 3D UI, the entire screen is magnetic for mounting on a metal surface, and the whole package is being projected for less than $300.

nandemoari writes "As his administration continues to work on a stimulus plan that can save America's economy, Obama's latest course of action will see millions of dollars being allocated to heighten cyber security. The move will assist government officials in preventing future attacks on the United States. The President recently addressed his 2010 budget, outlining funding plans that will grant the Department of Homeland Security $355 million to secure the nation's most essential computer systems. The money will be spent on both government and private groups, with much of the funding going to the National Cyber Security Division and the Comprehensive National Cyber Security Initiative programs."

Save the Netbooks writes "We discussed Psion sending C&Ds late last year over international trademarks held on the term 'netbook' and Dell accusing Psion of fraud last week. Since then Intel has joined in by suing Psion in federal court. On Friday Psion counter-sued Intel (court filing, PDF). SaveTheNetbooks.com has an analysis here. Psion has demanded a jury trial, profits, treble damages, destruction of material bearing the mark 'netbook' and the netbook.com domain (among other things), claiming that they are still actively selling netbooks despite also revealing sales figures showing a minuscule market share. It seems that declaring victory may have been a little premature as it will be months before the dispute plays out in court."

nk497 writes "The release of the beta for the next version of Apple's Safari browser last week helped drive Apple's market share above ten per cent. The Safari beta has gained users at a rate of about 0.5 per cent a day since its release, topping one per cent by day four. For comparison, Microsoft's beta of IE took six months to hit one percent, Chrome needed almost a month, and Firefox 3 took a week."

supaneko writes "I am working with a non-profit that will eventually host a massive online self-help archive and community (using FTP and HTTP services). We are expecting 1,000+ unique visitors / day. I know that having only one server to serve this number of people is not a great idea, so I began to look into clusters. After a bit of reading I determined that I am looking for high availability, in case of hardware fault, and network load balancing, which will allow the load to be shared among the two to six servers that we hope to purchase. What I have not been able to determine is the 'perfect' solution that would offer efficiency, ease-of-use, simple maintenance, enjoyable performance, and a notably better experience when compared to other setups. Reading about Windows 2003 Clustering makes the whole process sounds easy, while Linux and FreeBSD just seem overly complicated. But is this truly the case? What have you all done for clustering solutions that worked out well? What key features should I be aware for successful cluster setup (hubs, wiring, hardware, software, same servers across the board, etc.)?"

theodp writes "A 2004 study found some 10 million women lacking a cervix were still getting Pap tests. Only problem is, a Pap test screens for cervical cancer — no cervix, no cancer. With this tale, Newsweek's Sharon Begley makes her case for comparative-effectiveness research (CER), which is receiving $1 billion under the stimulus bill for studies to determine which treatments, including drugs, are more medically sound and cost-effective than others for a given ailment. Physicians, Begley says, must stop treatments that are rooted more in local medical culture than in medical science, embrace practices that have been shown scientifically to be superior to others, and ignore critics who paint CER as government control of doctors' decision-making."

ddelmonte writes in to tell us about a small near-earth object, discovered just 2 days ago, that is expected to pass within 64,000 km of our planet on March 2, 13:44 UT. NEO 2009 DD45 will be well inside the Moon's orbit and just under twice the altitude of geosynchronous satellites. According to Sky and Telescope, 2009 DD45's closest approach will be over the Pacific west of Tahiti, so observers in Australia, Japan, and perhaps Hawaii will have the best chance of spotting it with, say, an 8-in. telescope. Here's where you can generate an ephemeris of the object for your location. At closest approach NEO 2009 DD45 will be moving half a degree per minute and peaking around magnitude 10.5. It will be brighter than 13th magnitude for only a few hours.

ZosX writes "An article over at Popular Mechanics announces that, for the first time, solar cells have been manufactured for the much sought-after figure of $1/Watt. They also talk about a new study of the cost of the particular raw materials used in different manufacturing processes. The conclusion is that the company that just achieved the $1/W milestone, using cadmium telluride technology, may not prove to be the long-term winner capable of meeting demand when it rises into the terawatt range."

Igor Hardy writes "I've conducted an interesting interview concerning a new episodic indie adventure game series called Casebook. What's quite uncommon, especially for these kinds of independently developed and published productions, is that they include professionally created FMV — all of the footage is filmed in real locations. Yet what's even more interesting is that the games use an innovative photographic technology which recreates a fully explorable 3D environment through the use of millions of photos instead of building from polygons. The specifics of how it works are explained by Sam Clarkson, the creative director of the series."

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."

marcellizot writes "What would you say if I told you that there are people out there that want to make sharing your media between devices over a home network illegal? According to Jim Burger, a Washington, D.C attorney who deals with piracy in the broadcasting industry, certain broadcasters want to do just that. Speaking in a recent podcast, Burger remarked that the broadcasting industry is keen to put controls on sharing media between devices even if those devices are on a home network and even if the sharing is strictly for personal use. When pressed as to why broadcasters would want to do this, Burger replied simply 'because they want you to pay for that right.'"
