Bill Gates's New Version of the Einstein Letter 407

Posted by Soulskill from the did-he-just-godwin-the-green-revolution dept.
dcblogs writes "In 1939, Albert Einstein sent 'F.D. Roosevelt, President of the United States,' a letter with a warning about Germany's interest in a new type of energy with potential for use as a powerful bomb. The letter also outlined the competitive threat posed by Germany and steps for improving US research efforts. Last week, Bill Gates, along with GE's CEO and others, met with President Obama to deliver their own message: that of the top 30 companies in the world working on alternative energy, only four are in the US. Similar to Einstein's point and recommendations, Gates and his allies are asking the US to view the alternative energy push as a competitive threat posed by other nations, particularly China, which may be doing a better job in bringing its engineering talent and money to bear on this problem."

What Knowledge Gaps Do Self-Taught Programmers Generally Have? 396

Posted by ScuttleMonkey from the mind-the-gap dept.
BeardedChimp writes "I, like many others here, have learned to program by myself. Starting at a young age and learning through fiddling I have taught myself C++, Java, python, PHP, etc., but what I want to know is what I haven't learned that is important when taught in a traditional computer science curriculum. I have a degree in physics, so I'm not averse to math. What books, websites, or resources would you recommend to fill in the gaps?"

Best Buy $39.95 "Optimization" At Best a Waste of Money 504

Posted by ScuttleMonkey from the hooray-for-corporate-scams dept.
DCFC writes "The Consumerist deconstructs the appalling 'optimization service' that Best Buy has been pushing on consumers in recent weeks. The retailer charges 40 bucks to give you a slower PC, and make bizarre claims that it makes it go 200% faster. 'We ran the 3DMark 2003 graphics benchmark on each laptop, comparing optimized and non-optimized settings. For two of our samples, the Gateway and Toshiba, performance changes were negligible. On the Asus laptop, however, optimized tests actually scored about 32% worse than the non-optimized setup. We have been unable to isolate the source of this performance change. On none of the three tested laptops did the optimized settings give a performance boost in our test.'"

Thorium, the Next Nuclear Fuel? 710

Posted by Soulskill from the plenty-on-the-auction-house dept.
mrshermanoaks writes "When the choices for developing nuclear energy were being made, we went with uranium because it had the byproduct of producing plutonium that could be weaponized. But thorium is safer and easier to work with, and may cause a lot fewer headaches. 'It's abundant — the US has at least 175,000 tons of the stuff — and doesn't require costly processing. It is also extraordinarily efficient as a nuclear fuel. As it decays in a reactor core, its byproducts produce more neutrons per collision than conventional fuel. The more neutrons per collision, the more energy generated, the less total fuel consumed, and the less radioactive nastiness left behind. Even better, Weinberg realized that you could use thorium in an entirely new kind of reactor, one that would have zero risk of meltdown. The design is based on the lab's finding that thorium dissolves in hot liquid fluoride salts. This fission soup is poured into tubes in the core of the reactor, where the nuclear chain reaction — the billiard balls colliding — happens. The system makes the reactor self-regulating: When the soup gets too hot it expands and flows out of the tubes — slowing fission and eliminating the possibility of another Chernobyl. Any actinide can work in this method, but thorium is particularly well suited because it is so efficient at the high temperatures at which fission occurs in the soup.' So why are we not building these reactors?"

Android's Success a Threat To Free Software? 416

Posted by Soulskill from the unintended-consequences dept.
Glyn Moody writes "Two years after its launch, Google's Linux-based Android platform is finally making its presence felt in the world of smartphones. Around 20,000 apps have been written for it. Although well behind the iPhone's tally, that's significantly more than just a few months ago. But there's a problem: few of these Android apps are free software. Instead, we seem to be witnessing the birth of a new hybrid stack — open source underneath, and proprietary on top. If, as many believe, mobile phones will become the main computing platform for most of the world, that could be a big problem for the health of the free software ecosystem. So what, if anything, should the community be doing about it?"

Black Soot May Be Aiding Melting In the Himalayas 336

Posted by kdawson from the not-yeti dept.
Hugh Pickens writes "The Himalayas, home to some 10,000 glaciers, are the main source of replenishment to lakes, streams, and some of the continent's mightiest rivers, on which millions of people depend for their water supplies. Since the 1960s, the acreage covered by Himalayan glaciers has declined by more than 20 percent with a rate of warming twice the global average over the past 30 years. Now Live Science reports that tiny particles of pollution known as 'black carbon' — and not heat-trapping greenhouse gases — may be causing much of the rapid melting of glaciers in the Himalayas. 'Tibet's glaciers are retreating at an alarming rate,' says James Hansen, director of NASA's Goddard Institute for Space Studies in New York City. 'Black soot is probably responsible for as much as half of the glacial melt, and greenhouse gases are responsible for the rest.' The circulation of the atmosphere in the region causes much of the soot-laden air to 'pile up' against the Himalayas. The soot mixes with other dust from nearby deserts, creating a massive brown cloud visible from space that absorbs incoming solar radiation. As this layer heats up in the Himalayan foothills, it rises and enhances the seasonal northward flow of humid monsoon winds, forcing moisture and hot air up the slopes of the mountain range."

Facebook Campaign Decides UK Christmas Music Charts 362

Posted by kdawson from the rage-against-the-commercialization dept.
uglyduckling writes "A grassroots Facebook campaign has pushed the 1990s Rage Against the Machine song 'Killing in the Name Of' to the top of the British music charts for Christmas. The campaign was planned to prevent the X-Factor winner from charting Christmas number one, as has been the case for the past four years. It was supposedly a kick against the commercialism of Christmas and commercial dominance in the music scene, although Rage and the X-Factor winner Joe McElderry were actually signed to the same label. Despite this minor detail, it's interesting to note that this is the first song to reach the number one spot through downloads alone in the UK, and is a testament to the organizational power of social networking sites like Facebook. The Facebook group also asked for donations to charity, and has raised £70,000 for the homeless charity Shelter."

AU Authority Moves To Censor Net Filtering Protest Site 225

Posted by kdawson from the shortcutting-the-udrp dept.
An anonymous reader writes "On Friday the Sydney Morning Herald reported that an Internet censorship protest site had been set up under the banner 'Stephen Conroy: Minister for Fascism' and was ironically registered under the very name of the Australian Communications Minister responsible for trying to mandate the compulsory filtering scheme in federal law, stephenconroy.com.au. Within hours of the story being published, auDA, the Australian Domain Name Authority, had shut down the site, giving the owners only 3 hours to respond to a request to justify their eligibility for the domain. Normally auDA would allow several days to weeks for this process. An appeal to request an extension was denied, with no reason given. The site was quickly moved to a US domain, stephen-conroy.com in order to stay active while the dispute with auDA is resolved."

Grigory Perelman and the Poincare Conjecture 241

Posted by kdawson from the another-tortured-genius dept.
EagleHasLanded writes "Russian mathematician Grigory Perelman doesn't talk to journalists. Actually, he doesn't talk to anyone anymore. So we'll have to settle for insights via his biographer, Masha Gessen, who, strangely enough, has never talked to him either. But she has spoken with just about everyone who has ever had any significant interaction with Perelman, and the result is the book Perfect Rigor, which more than adequately explains why Perelman has gone into self-imposed exile, and why he probably won't collect the million dollars he won by solving the Poincare Conjecture."

Gran Turismo Gamer Becomes Pro Race Driver 249

Posted by samzenpus from the practice-makes-profession dept.
An anonymous reader writes "Back in 2008, Lucas Ordonez lived what seemed like an ordinary existence. The 22-year-old Spanish student was an avid motorsports fan, but he lacked the suitable investment necessary to become a professional race driver and had virtually given up on racing. Besides, he was already knee-deep in trying to complete a Master of Business Administration (MBA). But it was Ordonez' passion for virtual racing, particularly his love of Gran Turismo, that made him stand out from his peers — both off the track and eventually on it. In just a few months, Ordonez' life was transformed from console dreamer to racing the real thing at a real race track in Europe. And Ordonez managed to do the unthinkable: go from the couch car to the race car, and win."

Somali Pirates Open Up a "Stock Exchange" 666

Posted by kdawson from the send-in-the-sba dept.
reginaldo writes to clue us that pirates in Somalia have opened up a cooperative in Haradheere, where investors can pay money or guns to help their favorite pirate crew for a share of the piracy profits. "'Four months ago, during the monsoon rains, we decided to set up this stock exchange. We started with 15 "maritime companies" and now we are hosting 72. Ten of them have so far been successful at hijacking,' Mohammed [a wealthy former pirate who took a Reuters reporter to the facility] said. ... Piracy investor Sahra Ibrahim, a 22-year-old divorcee, was lined up with others waiting for her cut of a ransom pay-out after one of the gangs freed a Spanish tuna fishing vessel. 'I am waiting for my share after I contributed a rocket-propelled grenade for the operation,' she said, adding that she got the weapon from her ex-husband in alimony. 'I am really happy and lucky. I have made $75,000 in only 38 days since I joined the "company."'"

CERN Physicist Warns About Uranium Shortage 581

Posted by timothy from the switch-to-geraniums dept.
eldavojohn writes "Uranium mines provide us with 40,000 tons of uranium each year. Sounds like that ought to be enough for anyone, but it comes up about 25,000 tons short of what we consume yearly in our nuclear power plants. The difference is made up by stockpiles, reprocessed fuel and re-enriched uranium — which should be completely used up by 2013. And the problem with just opening more uranium mines is that nobody really knows where to go for the next big uranium lode. Dr. Michael Dittmar has been warning us for some time about the coming shortage (PDF) and has recently uploaded a four-part comprehensive report on the future of nuclear energy and how socioeconomic change is exacerbating the effect this coming shortage will have on our power consumption. Although not quite on par with zombie apocalypse, Dr. Dittmar's final conclusions paint a dire picture, stating that options like large-scale commercial fission breeder reactors are not an option by 2013 and 'no matter how far into the future we may look, nuclear fusion as an energy source is even less probable than large-scale breeder reactors, for the accumulated knowledge on this subject is already sufficient to say that commercial fusion power will never become a reality.'"

These auditors are exactly the individuals that benefit from pointing out inadequacies in security. I covered the "company laptop" and "USB" issue - if people have physical access to a system, then obviously, it's vulnerable. What does "100% isolated" mean? Controlled using rubber gloves behind a glass window of a clean room? These guys are simply pointing out that you can't make something 100% secure, which is a universal truth. All you can do is make it uneconomical or unrealistic, or at least very difficult. The auditor you heard had a whole lot to say about nothing.

And it's not necessary to begin your post with "uhhh... right."
