Velcroman1 writes "Two scientists at Yale University have built the laser's first doppelganger: the anti-laser. While a conventional laser emits a constant beam of light in one direction, the anti-laser simply does the opposite. It takes that same steady light stream and interacts with it in such a way that it absorbs and cancels out the light. And scientists hope the strange creation could help the fight against cancer. A. Douglas Stone, one of the two researchers behind the project, said he came up with the idea for a 'nega-laser' when working with equations for a random laser with his partner in crime, Hui Cao. 'I figured, if we just somehow illuminated the cavity, and replaced the gain medium with something that tends to absorb light, we could essentially reverse the process,' Stone said. Oh, that makes sense."

Vectormatic noted the rumor floating around that the most recent PS3 patch has a backdoor, and "Sony can now remotely execute code on the PS3 as soon as you connect. This can do whatever Sony wants it to do, such as verifying system files or searching for homebrew. Sony can change the code and add new detection methods without any firmware updates."

thecarchik writes "Ford's new system works over a dedicated short-range WiFi system on a secure channel allocated by the FCC. The company says the system one-ups radar safety systems by allowing full 360-degree coverage even when there's no direct line of sight. Scenarios where this could benefit safety or traffic? Predicting collision courses with unseen vehicles, seeing sudden stops before they're visible, and spotting traffic pattern changes on a busy highway. The National Highway Traffic Safety Administration (NHTSA) reported in October that vehicle-to-vehicle warning systems could address nearly 80 percent of reported crashes not involving drunk drivers. As such, it could potentially save tens of thousands of lives per year."

I Don't Believe in Imaginary Property writes "Craig Mundie, Microsoft's Chief Research and Strategy Officer, called for the creation of an 'Internet Driver's License' at the World Economic Forum in Davos, saying, 'If you want to drive a car you have to have a license to say that you are capable of driving a car, the car has to pass a test to say it is fit to drive and you have to have insurance.' Of course, there are quite a few problems with this. For starters, internet use cannot yet cause death or dismemberment like car accidents can; and this would get rid of most of the good of internet anonymity while retaining all of the bad parts, especially in terms of expanding the market for stolen identities. Even though telephone networks have long been used by scammers and spammers/telemarketers, we've never needed a 'Telephone Driver's License.'"

CNet is reporting that Netflix has opened up its "Watch Instantly" feature to Mac users (here is Netflix's blog entry). They accomplished this by using Microsoft's Silverlight technology on both platforms, abandoning the Windows Media Player solution that had been employed in the first, Windows-only, version. Silverlight's DRM capabilities meet Netflix's needs, apparently. Netflix warns that this is beta software. Mac users can opt in here, then watch instantly with Safari or Firefox 2+, with the Silverlight plugin in place. Movie selection is somewhat limited.

vigmeister writes "I hopped on the netbook bandwagon early this year in a rather odd fashion by picking up an outdated portable tablet (Fujitsu P1510) which just about matches the latest, greatest netbooks for their performance and portability features, while nipping them by managing to give me a better battery life. I've been happy using XP Tablet on this machine until recently, when I started thinking that by optimizing the OS for targeted use, I may be able to squeeze more out of the device. So, my questions are: What OS would you recommend for a netbook/outdated laptop? Usage is typically light — web surfing (with multimedia), email, word processing, spreadsheet and reading PDFs. Also, what OS would you recommend for a ultraportable tablet? Usage is similar to a netbook; there's a little more document editing going on, and good handwriting recognition and note-taking software would be great." Read on for further details about vigmeister's question.

r writes "The New York Times reports on a security flaw discovered in the new Android phones. The article is light on details, but it hints at a security hole in the browser, allowing for trojans to install themselves in the same security partition as the browser: 'The risk in the Google design, according to Mr. Miller, who is a principal security analyst at Independent Security Evaluators in Baltimore, lies in the danger from within the Web browser partition in the phone. It would be possible, for example, for an intruder to install software that would capture keystrokes entered by the user when surfing to other Web sites. That would make it possible to steal identity information or passwords.'"

What is 10' tall, has six hydraulic legs, and is powered by the wind and solar panels? The prototype pod house built by art collective N55 in Copenhagen, Denmark. With the help of MIT, N55 built the pod over a two-year period at a cost of £30,000. Designers say it provides a solution to the problem of rising water levels as the house can simply walk away from floods. One of the designers says, "This house is not just for travellers but also for anyone interested in a more general way of nomadic living." It won't be long now until the Japanese make Howl's Moving Castle.

Technologizer writes "Some folks are outraged over the lack of FireWire in the new MacBook released this week. But Apple wouldn't be Apple if it didn't move faster than any other computer company to kill technologies that may be past their prime. And history usually validates its decisions. We've posted a decade's worth of examples that prove the point."

riverman writes "I have been 'provisioned' at the school where I work to teach a new Computer Science/Programming course. I'm supposed to be teaching everything from the very-very basics (i.e. where that myspace thing is in your computer monitor, and how it knows who your friends are) to the easy-advanced (i.e. PHP classes and Python/Google App Engine). I'm an experienced programmer, but I'm not sure where to start — I could easily assume that my students know something basic they don't. Are there any resources on the internet that could help me find a solid curriculum? What are your suggestions?" I'm sure many of us have gone through intro-level programming courses of some sort; what are some things your teacher or professor did that worked well, and what didn't work at all?
