Submission + - Multi threaded programming without the pain

holden karau writes: "Gigahertz are out and cores are in. Now more than ever, programmers must begin to develop applications that takes advantage of increasing number of 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."

Submission + - Gozi trojan analysis leads to Russian data hoard

Stolen Identity writes: "An attack by a single trojan variant compromises thousands, circumvents SSL, and uploads the results to a Russian dropzone server. 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."

Submission + - New Inkjet Technology 5 to 10 Times Faster

sarahbau writes: "Silverbrook's new Memjet technology can print 60 full-color pages per minute. 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."

Submission + - Server power consumption doubled over past 5 years

Watt's up writes: A new study shows an alarming increase in server power consumption over the past five years. In the US, servers (including cooling equipment) consumes 1.2% of all the electricity in 2005, up from 0.6% in 2000. The trend is the similar worldwide. 'If current trends continue, server electricity usage will jump 40 percent by 2010, driven in part by the rise of cheap blade servers, which increase overall power use faster than larger ones. Virtualization and consolidation of servers will work against this trend, though, and it's difficult to predict what will happen as data centers increasingly standardize on power-efficient chips.
