beachdog writes "The ham radio magazine QST (membership or library) carries a short article about a 144 core microcontroller being offered by www.greenarraychips.com. To quote the wee bit overenthuiastic article first sentence: "Whoever says that "old guys" can't keep up with technology has never heard of GreenArrays." The Chairman and CTO of GreenArrays is the co founder of Forth, Inc., 1973. That is, 39 years ago."

+ - Tech: Magnetic Storage Written By Heat? ->

Submitted by

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."

Submitted by mikejuk
mikejuk (1801200) writes "Stanford University is offering the online world more of its undergraduate level CS courses. These free courses consist of You Tube videos with computer-marked quizzes and programming assignments. The ball had been started rolling by Sebastian Thrun and Peter Norvig's free online version of their Stanford AI class, for which they hoped to reach an audience in the order of a hundred thousand, a target which they seem to have achieved.
As well as the previously announced Machine learning course you can now sign up to any of: Computer Science 101, Software as a Service, Human-Computer Interaction, Natural Language Processing, Game Theory, Probabilistic Graphical Models, Cryptography and Design and Analysis of Algorithms.
Almost a complete computer science course and they are adding more. Introductory videos and details are available from each courses website."

antdude writes "CNNMoney report that "... your cell phone may be tracked this year. Starting on Black Friday and running through New Year's Day, two United States/U.S. malls ... will track guests' movements by monitoring the signals from their cell phones.

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..."

Seen on Blue's News."

+ - Can Rogue Web Browsers Make A Comeback?->

Submitted by Orome1
Orome1 (1901578) 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."

+ - Schools in Portugal Moving to OSS->

Submitted by thyristor pt
thyristor pt (1507463) 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?"
