Bolivia Is the Saudi Arabia of Lithium

Apr 30

tcd004 writes “You can literally scrape valuable lithium off the ground of many Bolivian salt flats. The country is poised to be the center of world lithium battery production, reaping the benefit of the metal’s skyrocketing value. ‘The US Geological Survey says 5.4 million tons of lithium could potentially be extracted in Bolivia, compared with 3 million in Chile, 1.1 million in China and just 410,000 in the United States. … Ailing automakers in the United States are pinning their hopes on lithium. General Motors next year plans to roll out its Volt, a car using a lithium-ion battery along with a gas engine. Nissan, Ford and BMW, among other carmakers, have similar projects.’ However, the government fears foreign countries might exploit their natural resources, so for the time being, the salt flats remain untouched.”

Russian Manned Space Vehicle May Land With Rockets

Apr 30

The Narrative Fallacy writes “Russia’s next-generation manned space vehicle may be equipped with thrusters to perform a precision landing on its return to Earth. Previous manned missions have landed on Earth using a parachute or, in the case of space shuttles, a pair of wings. Combined with retractable landing legs and a re-usable thermal protection system, the new system promises to enable not only a safe return to Earth, but also the possibility of performing multiple space missions with the same crew capsule. The spacecraft will fire its engines at an altitude of just 600-800m, as the capsule is streaking toward Earth after re-entering the atmosphere at the end of its mission. After a vertical descent, the precision landing would be initiated at the altitude of 30m above the surface. Last July, Korolev-based RKK Energia released the first drawings of a multi-purpose transport ship, known as the Advanced Crew Transportation System (ACTS), which, at the time, Russia had hoped to develop in co-operation with Europe. ‘It was explained to us how it was supposed to work and, I think, from the technical point of view, there is no doubt that this concept would work,’ says Christian Bank, the leading designer of manned space systems at EADS-Astrium in Bremen, Germany. However, the design of the spacecraft’s crew capsule had raised eyebrows in some quarters, as it lacked a parachute — instead sporting a cluster of 12 soft-landing rockets, burning solid propellant. Inside Russia, the idea apparently has many detractors. During the formal defense of the project, one high-ranking official skeptical of the rocket-cushioned approach to landing reportedly used an unprintable expletive to describe what was going to happen to crew members unlucky enough to encounter a rocket engine failure a few seconds before touchdown.”

A Touch Screen With Morphing Buttons

Apr 30

Al writes “Researchers at Carnegie Mellon University have created a touch screen that can also produce physical buttons. Graduate student Chris Harrison and professor Scott Hudson use a projector and infrared sensor below the screen to illuminate it and make it touch-sensitive, and the physical buttons are created using air pumps below the surface. They say this type of screen could be particularly useful when a simple, flat touch-screen is too distracting, for example in a vehicle dashboard.”

Is Apache Or GPL Better For Open-Source Business?

Apr 30

mjasay writes “While the GPL powers as much as 77% of all SourceForge projects, Eric Raymond argues that the GPL is ‘a confession of fear and weakness’ that ’slows down open-source adoption’ because of the fear and uncertainty the GPL provokes. Raymond’s argument seems to be that if openness is the winning strategy, an argument Michael Tiemann advocates, wouldn’t it make sense to use the most open license? Geir Magnusson of the Apache Software Foundation suggests that there are few ‘pure’ GPL-only open-source projects, as GPL-prone developers have to ‘modify it in some way to get around the enforcement of Freedom(SM) in GPL so people can use the project.’ But the real benefit of Apache-style licensing may not be for developers at all, and rather accrue to businesses hoping to drive adoption of their products: Apache licensing may encourage broader, deeper adoption than the GPL. The old GPL vs. BSD/Apache debate may not be about developer preferences so much as new business realities.”

OIN Posts Details of Microsoft’s Anti-Tom Tom Patents

Apr 29

number6x writes “LinuxDevices.com is reporting that the Open Invention Network has posted the details of three of the eight patents used by Microsoft in the Tom Tom suit (which Tom Tom settled last month), asking the community for prior art. These patents cover aspects of the FAT file system. You can find them on Post-Issue.org — see numbers 5579517, 5758352, and 6256642. OIN CEO Keith Bergelt believes that these three patents are of tenuous validity and will probably not survive a review. Bergelt believes that there’s a good chance that the USPTO may well invalidate them before the end of the year.

Apple May Bring a Non-iPhone To Verizon Wireless

Apr 29

The Narrative Fallacy writes “According to BusinessWeek, Verizon Wireless is in talks with Apple to distribute two new iPhone-like devices that are not iPhones. (Apple has created prototypes.) AT&T’s contract with Apple, which has not been made public, is believed to cover all models of the iPhone, but only the iPhone. So if Apple builds something that isn’t an iPhone — and perhaps doesn’t even make cellular calls — they won’t be violating their exclusivity contract with AT&T, which runs through at least 2010. One device is a smaller, less expensive calling device described by a person who has seen it as an ‘iPhone lite.’ The other is a media pad, said to be smaller than a Kindle but with a bigger screen, that would let users listen to music, view photos, watch high-definition videos, and make calls over a Wi-Fi connection. (And read books?) Apple could use the prospect of an iPhone-esque device as leverage to prevent Verizon Wireless from introducing the Palm Pre, or at least to delay its introduction on Verizon’s network. ‘The media pad category might go to Verizon,’ said one person who has seen the device. ‘We are talking about a device where people will say, “Damn, why didn’t we do this?” Apple is probably going to define the damn category.’” Reader stevegee58 writes with word that Verizon may be playing both ends against the middle. Marketwatch reports that Microsoft and Verizon are in talks to develop a touch-screen mobile phone that would run on Windows Mobile.

Should the US Go Offensive In Cyberwarfare?

Apr 29

The NYTimes has a piece analyzing the policy discussions in the US around the question of what should be the proper stance towards offensive cyberwarfare. This is a question that the Bush administration wrestled with, before deciding that the outgoing president didn’t have the political capital left to grapple with it. The article notes two instances in which President Bush approved the use of offensive cyberattacks; but these were exceptions, and the formation of a general policy was left to the Obama administration. “Senior Pentagon and military officials also express deep concern that the laws and understanding of armed conflict have not kept current with the challenges of offensive cyberwarfare. Over the decades, a number of limits on action have been accepted — if not always practiced. One is the prohibition against assassinating government leaders. Another is avoiding attacks aimed at civilians. Yet in the cyberworld, where the most vulnerable targets are civilian, there are no such rules or understandings. If a military base is attacked, would it be a proportional, legitimate response to bring down the attacker’s power grid if that would also shut down its hospital systems, its air traffic control system, or its banking system?”

A $99 Graphics Card Might Be All You Need

Apr 29

Vigile writes “With the release of AMD’s latest budget graphics card, the Radeon HD 4770, the GPU giant is bringing a lot of technology to the table. The card sports the world’s first 40nm GPU (beating out CPUs to a new process technology for the first time), GDDR5 memory, and 640 stream processors, all for under $100. What is even more interesting is that as PC gaming has evolved it appears that a $99 graphics card is all you really need to play the latest PC titles — as long as you are comfortable with a resolution of 1920×1200 or below. Since so few PC gamers have screens larger than that, could the world of high-end PC graphics simply go away?”

Senator Arlen Specter Becomes a Democrat

Apr 29

Akido37 was one of many readers letting us know that US Sen. Arlen Specter has changed parties to become a Democrat. This gives the Democrats 59 seats in the Senate, and 60 if and when Al Franken gets seated from Minnesota. However, Specter said in his announcement that he will not be an automatic 60th vote for breaking Republican filibusters. While the senator’s move seems to have surprised many Republicans, it is understandable to moderate Republican Sen. Olympia Snowe of Maine, who said, “You haven’t certainly heard warm encouraging words of how they [Republicans] view moderates. Either you are with us or against us.” Specter noted that in his home state of Pennsylvania, 200,000 formerly Republican voters switched party allegiance last year.

Phorm "Edited and Approved" UK Government Advice

Apr 29

Barence was one of several readers to send in word that the UK Home Office checked whether its interpretation of the law suited Phorm, before issuing advice on the legality of the controversial advertising service. The Home Office and Phorm entered a dialogue about the company’s services back in August 2007, at Phorm’s request. In an email sent to Phorm in January 2008, a Home Office official writes: ‘I should be grateful if you would review the attached document, and let me know what you think.’ After Phorm made deletions and amendments to the document, the Home Office sent another email to the company stating: ‘If we agree this, and this becomes our position do you think your clients and their prospective partners will be comforted.’ From the BBC: “Baroness Sue Miller, Liberal Democrat spokeswoman on Home Affairs, told BBC News: ‘My jaw dropped when I saw the Freedom of Information exchanges. … Anything the Home Office now says about Phorm is completely tainted.’”
