Submission Tech: Magnetic Storage Written By Heat? ->

judgecorp writes: "Scientists have demonstrated that magnetic storage can be written by thermal pulses, delivered by laser. The team, led from the University of York, showed that the polarity of a magnetic domain could be reversed by heat from a laser beam. This is unexpected. It was previously thought that could heat could only destroy magnetic polarisation, not re-align it. It could lead to hard disks that can be written hundreds of times faster, and using less energy."

While the data that's collected is anonymous, it can follow shoppers' paths from store to store.

The goal is for stores to answer questions ...

While U.S. malls have long tracked how crowds move throughout their stores, this is the first time they've used cell phones.

But obtaining that information comes with privacy concerns..."

Submission Can Rogue Web Browsers Make A Comeback?->

Orome1 writes: Before the survey scams, there were rogue web browsers. They were very popular in 2006 and 2007, when old-school ad vendors were at their peak. The majority of such browsers are actually skins wrapped another web browser, written in Visual Basic. They were a way to make a lot of cash from affiliate programs and a way to make users install additional malware on their machines. GFI's Christopher Boyd talks about how rogue web browsers changed through the years, the dangers lurking behind them and the likelihood of them making a comeback — this time on mobile platforms.

Submission Schools in Portugal Moving to OSS->

thyristor pt writes: In light of massive national budget cuts, the Portuguese government will force public schools to move to free/open source software . Schools with some 50.000 outdated computers won't see their software licenses renewed, the main reason being the cost of hardware upgrade inherent to mostly Microsoft software updates.
Will the Euro debt crisis be a driving force to the spreading of open source software?
