Now in its seventh decade and in its fifth home, the computer with its flashing lights and clattering printers and readers provides an awe-inspiring display for visiting school groups and the general public keen to learn about our rich computer heritage."
Hugh Pickens writes writes: "NPR reports that Sweden's program of generating energy from garbage is wildly successful, but recently its success has also generated a surprising issue: There is simply not enough trash. Sweden has recently begun to import about eight hundred thousand tons of trash from the rest of Europe per year to use in its power plants. Sweden already brings trash from Norway and hopes to get garbage from Italy, Romania, Bulgaria and the Baltic countries. Sweden creates energy for around 250,000 homes and powers one-fifth of the district heating system. Its incineration plants offer a look into the future where countries could potentially make money off of their trash instead of dumping. Landfilling of organic materials – a highly inefficient and environmentally degrading system (PDF) — has been forbidden in Sweden since 2005 and emissions of the greenhouse gas methane from landfills has fallen dramatically (PDF). "“I hope that we instead will get the waste from Italy or from Romania or Bulgaria or the Baltic countries because they landfill a lot in these countries," says Catarina Ostlund, a senior advisor for the country's environmental protection agency. "They don’t have any incineration plants or recycling plants, so they need to find a solution for their waste,”"

set in the Arctic Ocean for the least amount of sea ice coverage in the
satellite record, the ice surrounding Antarctica reached
its highest ever level. Sea ice extended over 19.44 million
square kilometers (7.51 million square miles) in 2012, according to the
National Snow and Ice Data Center (NSIDC). The previous record of
19.39 million kilometers (7.49 million square miles) was set in 2006." Ice extent is reaching an all-time
record high on the bottom of the planet just after ice reached an
record low on the top of the planet. What can it
mean? Either there will soon be more ice at the top or less ice
at the bottom or the planet will become seriously 'bottom heavy.'
Now there is something to worry about...
In the demonstration, the same CPU was cooled by thermal paste and the thermal sheet side-by-side, with the paste keeping the processor at a steady 53 degrees Celsius. The sheet achieved a slightly better 50 degrees Celsius. The actual CPU used in the demonstration wasn’t identified.
Sony wants to get the thermal sheet used in servers and for projection units, but I can definitely see this being an option for typical PC builds, too. It's certainly going to be less messy and probably a lot cheaper than buying a tube of thermal paste.

If you're using version 7 of IE and want to buy goods from major Australian online retailer Kogan, you'll be paying 6.8 percent more than those using alternative browsers or IE8 or IE9. Kogan this week said it was fed up with the high costs of keeping its web site compatible with IE7, so it's passing the cost onto those who use the browser. Sounds like it's about time to switch;)

The experimental Boeing X37-B has been circling Earth at 17,000 miles per hour and was due to land in California in December. It is now expected to land in mid to late June. And still, no one knows what the space drone has been doing up there all this time."

Once Windows 8 is released, hardware manufacturers will be forced to ship machines that refuse to run any software that is not explicitly approved by Microsoft — and that includes competing operating systems like Linux.
Technically Fedora didn't have to go down this path. But, as this article explains, they are between a rock and a hard place: if they didn't pay Microsoft to let them onto the PC platform, they would have to explain to their potential users how to mess with firmware settings just to install the OS.
How long before circumventing the secure boot mechanism is considered a DMCA violation and a felony?"
jjp9999 writes: Based on claims that silicon chips could be infected, security researcher Sergei Skorobogatov claims he and his team developed chip scanning software to put this to the test. They got their hands on a US military chip "that is highly secure with sophisticated encryption standards," that also happens to be manufactured in China. What they found was the chip has a backdoor on it that can disable the chip or reopen it at will. "This particular chip is prevalent in many systems from weapons, nuclear power plants to public transport. In other words, this backdoor access could be turned into an advanced Stuxnet weapon to attack potentially millions of systems. The scale and range of possible attacks has huge implications for National Security and public infrastructure," Skorobogatov writes on his blog.

Based on the operating hours of all civil nuclear reactors and the number of nuclear meltdowns that have occurred, scientists at the Max Planck Institute for Chemistry in Mainz have calculated that such events may occur once every 10 to 20 years (based on the current number of reactors) — some 200 times more often than estimated in the past."
toomuchtogrok writes: Imagine charging your phone as you walk, thanks to a paper-thin generator embedded in the sole of your shoe. This futuristic scenario is now a little closer to reality. Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a way to generate power using harmless viruses that convert mechanical energy into electricity. The scientists tested their approach by creating a generator that produces enough current to operate a small liquid-crystal display. It works by tapping a finger on a postage stamp-sized electrode coated with specially engineered viruses. The viruses convert the force of the tap into an electric charge.
