cores present in computers today. However, up until now, multi-threaded development has not been easy. Researcher Stefanus Du Toit discusses and
demonstrates a software system (RapidMind) he co-authored that takes the pain away from multi-threaded programming in C++. For his demo, he created
a program on the PlayStation 3, consisting of thousands of chickens, each independently processed by a single processing core. The talk itself is
interesting, but the demo is golden."

A unique blow-by-blow analysis reveals evidence of cooperation between groups of malware specialists acting as service providers and points to the future of malware's growing underground economy."
robacarp writes: "After three years of dedicated work researchers at MIT solved the 110 year old E8 math problem — thus simplifying the 248th dimension. The solution "took researchers two years of 'pencil and paper' work and one more for software writing before the solution could be tackled by computer" and produced "a file 60 gigabytes in size" in "77 hours on the Sage supercomputer." Sadly the article also puts it in terms we can understand: "The calculation created a file 60 gigabytes in size, enough to store music that could play for 45 days in the MP3 format."

"Supreme forces always influenced people's choice. In the present-day world it is getting more and more difficult for the Providence to help people make their choices — the Spirit of Luck is unable to influence search engine results. However, the weather and solar activity are still entirely at the mercy of the supreme forces.
GoodLuckFinder.com picks a word out of your list according to unique weather conditions (the data comes from weather stations in real-time mode) or solar activity. The Spirit of Luck sees the words entered by you, insignificantly changes the weather (for instance, temperature changes by a few fractions of a grade) and tells you what your luck lies in."

Instead of having a print head that moves side to side like current inkjets, the print head spans the full width of the page, containing 70,400 nozzles in the A4 version. They also have a large format printer (51") that prints 6" to 1 foot per second. Products are expected to start shipping in late 2007."
