Comment: The RSA Patent was pretty much pure math too... (Score 2) 323

Those of you familiar with the RSA crypto algorithm will know it boils down to some incredibly simple number theory. ie. Generate two large primes p and q, and compute e and d such that: n = p.q e.d =~ 1 (mod n) All that math is in the patent, and that is the absolute essence of what they are patenting. But they get around this by drawing block diagrams for every possible way to create a communication channel that is encrypted and decrypted using RSA. They then just use the word device in the title, and Bob's your aunty's live in lover. The whole thing is peverse and absurd. But it's the way it has been for a long time, and this is unlikely to change anything.

See for example: http://www.tomshardware.com/reviews/firefox-chrome-opera,2558-4.html, or http://digitizor.com/2010/12/18/opera-11-benchmarked/ Opera places last in the memory usage stakes in all the tests. It is also slower than Chrome in most benchmarks. Firefox is probably the best overall for memory use, but I think for performance/memory tradeoff you cannot beat Chrome.

Gisg writes "The University of Arizona team reported that their genetically modified mosquitoes are immune to the malaria-causing parasite, a single-cell organism called Plasmodium. Riehle and his colleagues tested their genetically-altered mosquitoes by feeding them malaria-infested blood. Not even one mosquito became infected with the malaria parasite."

Australia Gets Its First Female Prime Minister 419

An anonymous reader writes "Julia Gillard has been elected unopposed to the Labor leadership, seizing power in a bloodless Parliament House coup after Prime Minister Kevin Rudd decided not to contest this morning's leadership ballot. Ms. Gillard will now be sworn in as Australia's first female prime minister. Emerging from this morning's meeting, she said she felt 'very honored' and said she would be making a statement shortly. Treasurer Wayne Swan now steps up as deputy prime minister. He was also elected unopposed."

Planned Nuclear Reactors Will Destroy Atomic Waste 344

separsons writes "A group of French scientists are developing a nuclear reactor that burns up actinides — highly radioactive uranium isotopes. They estimate that 'the volume of high-level nuclear waste produced by all of France’s 58 reactors over the past 40 years could fit in one Olympic-size swimming pool.' And they're not the only ones trying to eliminate atomic waste: Researchers at the University of Texas in Austin are working on a fusion-fission reactor. The reactor destroys waste by firing streams of neutrons at it, reducing atomic waste by up to 99 percent!"

Disney Releases 3D Texture Mapper Source Code 83

dsavi writes "Ptex, Walt Disney Animation Studio's cutting-edge 3D texture mapping library which was first used on nearly every surface in the 2008 animated feature Bolt, was released under the BSD license on Friday. Quoting the announcement on monophyl.com: 'We expect to follow Ptex with other open source projects that we hope the community will find beneficial. We will soon be launching a new Walt Disney Animation Studios Technology page under disneyanimation.com. It will include links to our open source projects as will as a library of recent publications.' This looks good for open source 3D graphics."

kkleiner writes "ARMAR, or Augmented Reality for Maintenance and Repair, is a head mounted display unit that provides graphic overlays to assist you in making repairs. An Android phone provides an interface to control the graphics you view during the process. Published in IEEE, and recently tested with the United States Marine Corps on an armored turret, ARMAR can cut maintenance times in half by guiding users to the damaged area and displaying 3D animations to demonstrate the appropriate tools and techniques."

NASA To Cryogenically Freeze Satellite Mirrors 47

Posted by Soulskill
from the ain't-it-cool dept.
coondoggie writes "NASA said it will soon move some of the larger (46 lb) mirror segments of its future James Webb Space Telescope into a cryogenic test facility that will freeze the mirrors to -414 degrees Fahrenheit (~25 K). Specifically, NASA will freeze six of the 18 Webb telescope mirror segments at the X-ray and Cryogenic Facility, or XRCF, at NASA's Marshall Space Flight Center in Huntsville, Alabama, in a test to ensure the critical mirrors can withstand the extreme space environments. All 18 segments will eventually be tested at the site. The test chamber takes approximately five days to cool a mirror segment to cryogenic temperatures."

Massive Solar Updraft Towers Planned For Arizona 572

Posted by samzenpus
from the juice-and-a-tan dept.
MikeChino writes "Australia-based EnviroMission Ltd recently announced plans to build two solar updraft towers that span hundreds of acres in La Paz County, Arizona. Solar updraft technology sounds promising enough: generate hot air with a giant greenhouse, channel the air into a chimney-like device, and let the warm wind turn a wind turbine to produce energy. The scale of the devices would be staggering — each plant would consist of a 2,400 foot chimney over a greenhouse measuring four square miles. The Southern California Public Power Authority has approved EnviroMission as a provider, although there’s still plenty of work to be done before the $750 million, 200 megawatt project can begin."

Minnesota Introduces World's First Carbon Tariff 303

Posted by timothy
from the hey-cut-that-crap-out dept.
hollywoodb writes "The first carbon tax to reduce the greenhouse gases from imports comes not between two nations, but between two states. Minnesota has passed a measure to stop carbon at its border with North Dakota. To encourage the switch to clean, renewable energy, Minnesota plans to add a carbon fee of between $4 and $34 per ton of carbon dioxide emissions to the cost of coal-fired electricity, to begin in 2012 ... Minnesota has been generally pushing for cleaner power within its borders, but the utility companies that operate in MN have, over the past decades, sited a lot of coal power plants on the relatively cheap and open land of North Dakota, which is preparing a legal battle against Minnesota over the tariff."
