The Bad Astronomer writes "What's the nearest star to Earth that can explode as a supernova? Spica, at 260 light years away, is the nearest massive star that can explode, but IK Pegasi — a Sirius-like binary composed of a normal star and a white dwarf — will also one day blow. At a distance of 150 light years, it's truly the closest supernova candidate. Happily, that's too far away to damage the Earth when it goes off — and it won't explode for millions of years at least, by which time it'll be even farther away. Either way, we're safe... for now."

medv4380 writes "38 Studios, run by Curt Shilling, is having a hard time paying its bills and employees. The gaming community hasn't been happy with the company since the issue with an Online Pass for Single Player Content, which we discussed previously. Now, 38 Studios has bounced a check intended as a payment on its $75 million loan from the state of Rhode Island. If the company defaults, Rhode Island taxpayers will have to cover the loan and interest, which could total nearly $100 million."

Facebook's much-hyped IPO kicked off today, but an anonymous reader points out that things didn't go quite as smoothly as investors hoped. "Public trading didn't get underway until about 11:30 a.m. ET, half an hour after it was supposed to. The delay was likely caused by the huge amount of interest in the stock – especially by retail investors. In the first few minutes of trading, Facebook shares were only up between 5 and 10 per cent and by noon were essentially back down to the IPO price of $38. Many observers had expected the stock to double in price by the end of the day, if not sooner." The NY Times has a data visualization showing how Facebook's IPO compares to other tech IPOs throughout the years, and how the first day of trading treated all of those companies. Meanwhile, the debate is lively over whether the social networking giant will be a good investment. "The banks helping take Facebook public want us to value this 8-year-old upstart at as much as $104 billion, more than Disney or Kraft Foods, though those companies earn three and four times more. That top valuation is also more than 100 times Facebook's earnings last year, versus 13 times for the average company. At such a high price, it will take years for this so-called earnings multiple to fall to a more reasonable level, and that's assuming the company can maintain its torrid earnings growth."

Sparrowvsrevolution writes "On Thursday, the House Judiciary Committee held a hearing to discuss a proposed bill to limit location tracking of electronic devices without a warrant — what it's calling the Geolocational Privacy and Surveillance Act, or the GPS Act. Ahead of that hearing, University of Pennsylvania computer science professor Matt Blaze submitted written testimony (PDF) telling Congress that phone carriers, as well as the law enforcement agencies with which they share data, can now use phones' proximity to cell towers and other sources of cellular data to track their location as precisely or even more precisely than they can with global positioning satellites. Thanks to the growing density of cell towers and the proliferation of devices like picocells and femtocells that transmit cell signals indoors, even GPS-less phones can be tracked with a high degree of precision and can offer data that GPS can't, like the location of someone inside a building or what floor they're on. With the GPS Act, Congress is considering expanding the ban on warrantless tracking of cars with GPS devices that the Supreme Court decided on in January. Blaze's testimony suggests they need to include non-GPS tracking of cell phones in that ban, a measure law enforcement agencies are strongly resisting."

bonch writes "Autoparts manufacturer Delphi has developed a diesel-like ignition engine running on gasoline, providing a potential 50 percent efficiency improvement over existing gas-powered engines. Engineers have long sought to run diesel-like engines on gasoline for its higher efficiency and low emissions. Delphi's engine, using a technique called gasoline-direct-injection compression ignition, could rival the performance of hybrid automobiles at a cheaper cost."

ananyo writes "A newly-discovered microbial community living tens of meters beneath the Pacific Ocean floor uses so little oxygen that researchers believe they may be living at the absolute minimum energy requirement needed to subsist. For years, scientists thought that the ascetic conditions of the deep sub-seabed — high pressure, minimal oxygen and a low supply of nutrients and energy — made such environments uninhabitable to any form of life. The discovery extends the lower bound for life (abstract). The surface of Mars, for instance, may be inhospitable, but there may be conditions below the surface that are reminiscent of the deep subsurface on Earth. As microbiologist Bo Jørgensen comments in the Nature piece, while the discovery does not mean there is life on Mars, 'it's now really challenging to show where there is no life.'"

Axolotl_Rose writes with news that Hewlett-Packard is preparing to cut around 30,000 jobs, close to 10% of its total workforce. CEO Meg Whitman reportedly wants to use that money instead for new products and for bolstering the sales force. From the NY Times: "China, which is one of H.P.’s highest growth areas, will probably be spared, as will its research and development efforts. Ms. Whitman, who became H.P.’s chief executive last September, 'is trying to build a new company,' one senior executive said of the job cuts. 'You can count this as a part of that.' The final plan is expected to be announced on Wednesday, when H.P. announces earnings for its second fiscal quarter. Considered a slow-moving giant in the tech industry, H.P. had revenue of $127 billion in fiscal 2011, but net earnings of just $7.1 billion. While it has a leading position in the sales of low-margin personal computers, H.P. has been late or unsuccessful in many recent tech trends like providing cloud computing services for big companies and smartphones and tablet computers." An article at Forbes suggests HP should instead 'retool' those jobs by recruiting makers and hackers, TED conference speakers, and others who have experience building and inventing things.

cedarhillbilly writes "In his new book The Geek Manifesto, Mark Henderson 'pleads for citizens who value science to force it onto the mainstream political agenda and other main walks of life.' There are some important questions that need answers: 'Do you have to give up your tech practice to undertake a public role?' Also, 'Is political life (compromise, working by consensus, irrationality) antithetical to the "geek" values?'" The Guardian's coverage sums up the idea nicely: "What I desperately want is a move toward an evidence-based culture in politics. Politicians are free to say: 'I think people on drugs should be punished because drugs are immoral.' That's a moral call, albeit a rather stupid one in my opinion. What they shouldn't do is say: 'I want to reduce drug use, and sending all users to prison is the most cost-effective way to achieve that.' That's not at moral call, it's a factual statement; as such it should be evidence-based, or else the person making it should shut the hell up."

Barence writes "Computer scientists have unveiled a computer chip that turns traditional thinking about mathematical accuracy on its head by fudging calculations. The concept works by allowing processing components — such as hardware for adding and multiplying numbers — to make a few mistakes, which means they are not working as hard, and so use less power and get through tasks more quickly. The Rice University researchers say prototypes are 15 times more efficient and could be used in some applications without having a negative effect."

New submitter kimtysirt sends this excerpt from a Bloomberg report about U.S. tariffs for Chinese solar panels: "The U.S. yesterday imposed tariffs of as much as 250 percent on Chinese-made solar cells to aid domestic manufacturers beset by foreign competition, though critics said the decision may end up raising prices and hurting the U.S. renewable energy industry. The U.S. Commerce Department ruled that Chinese manufacturers sold cells in the U.S. at prices below the cost of production and announced preliminary antidumping duties ranging from 31 percent to 250 percent, depending on the manufacturer. China criticized the action, saying the U.S. is hurting itself and cooperation between the world’s two largest economies. The decision is meant to provide a boost to the U.S. solar manufacturing industry, where four companies filed for bankruptcy in the past year."

wiredmikey writes "In December of 2009, after months of waiting, the Obama Administration named Howard Schmidt as the White House Cybersecurity Coordinator. After more than forty years in the IT community, the nation's first cyber czar will retire at the end of the month. Schmidt, after just over two years of government service, said he would retire in order to spend more time with his family and to entertain teaching opportunities in the cyber field. Schmidt was at the reins when the White House introduced its international strategy for cyberspace, and also helped create the controversial National Strategy for Trusted Identities in Cyberspace, an initiative that would allow people to obtain a single credential as a one-time password (on a token or mobile device) to do business on the Internet. Schmidt will be replaced by Michael Daniel, currently the head of the White House budget office's intelligence branch."

PageRank orders results based on how other web pages are connected to them via hyperlinks; the modified algorithm, NetRank, scans how genes and proteins in a cell are similarly connected through a network of interactions with their neighbors. This approach could also yield new therapies to help combat tumors."

'Try as you might to keep social networks at bay, mobile devices let people be in constant connection to their social networking vices over the cellular networks, which you can't block. Still, it's not completely impossible to stop social time-wasting over mobile: You can establish policies that, if enforced strongly enough, eliminate social networks from being accessed on company time. Treat it like smoking: Let employees take a 15-minute coffee/smoking/Facebook break and make them go to a designated area to do it.'"

There are loads of various features that have been incorporated into watches, but you usually only see a small, specialized set in a given watch. Budget is always a concern, but I am willing to invest in a quality time piece. In short, I'm not looking for a piece of jewelry; I'm looking for a gadget to wear on my wrist. Are there any neat, fun or just plain cool watches out there for techies? What do you have?"

MikeatWired writes "The malware business growing around Google Android — now the leading smartphone operating system — is still in its infancy. Today, many of the apps built to steal money from Android users originate from Russia and China, so criminal gangs there have become cyber-trailblazers. Sophos and Symantec on Wednesday released their latest Android malware discoveries written in Russian. While the language narrows the number of potential victims, the social-engineering tactics used to get Android users to install the malware is universal. The gang tracked by Sophos is using fake antivirus scanners, while Symantec is tracking cybercriminals using mobile websites to offer bogus versions of popular games. Sophos says the criminals are like other entrepreneurs launching startups. They're starting in Russia, but have far greater ambitions. 'I don't think we can say that they're necessarily using it as a testing ground — think of it more as a local business that as it grows may gain multinational ambitions,' Graham Cluley, senior technology consultant at Sophos, said in an email interview on Wednesday. The cyber scam tracked by Sophos was reported this week by GFI Lab, which discovered links to the bogus antivirus software on Twitter. Sophos dug deeper and found that the .ru domains pointed to the same Internet protocol address hosted in Ukraine."

Fluffeh writes "In recent times, it seems many Police Departments believe that recording them doing their work is an act of war with police officers, destroying the tapes, phones or cameras while arresting the folks doing it. But in a surprising twist, the U.S. Justice Department has sent letter (PDF) to attorneys for the Baltimore Police Department — who have been quite heavy handed in enforcing their 'Don't record me bro!' mantra. The letter contains an awful lot of lawyer babble and lists many court cases and the like, although some sections are surprisingly clear: 'Policies should prohibit officers from destroying recording devices or cameras and deleting recordings or photographs under any circumstances. In addition to violating the First Amendment, police officers violate the core requirements of the Fourteenth Amendment procedural due process clause when they irrevocably deprived individuals of their recordings without first providing notice and an opportunity to object.' There is a lot more and it certainly seems like a firm foothold in the right direction."

Stowie101 writes in with a story about your Blu-ray audio getting better. "The audio on most Blu-ray discs is sampled at 48kHz. Even the original movie tracks are usually only recorded at 48kHz, so once a movie migrates to disc, there isn't much that can be done. Dolby's new system upsamples that audio signal to 96kHz at the master stage prior to the Dolby TrueHD encoding, so you get lossless audio with fewer digital artifacts. The 'fewer digital artifacts' part comes from a feature of Dolby's upsampling process called de-apodizing, which corrects a prevalent digital artifact known as pre-ringing. Pre-ringing is often introduced in the capture and creation process and adds a digital harshness to the audio. The apodizing filter masks the effect of pre-ringing by placing it behind the source tone — the listener can't hear the pre-ringing because it's behind the more prevalent original signal."

MrSeb writes "Using BrainGate, the world's most advanced brain-computer interface, a woman with quadriplegia has used a mind-controlled robot arm to serve herself coffee — an act she hasn't been able to perform for 15 years. BrainGate, which is being developed by a team of American neuroscientists from Brown and Stanford universities, and is currently undergoing clinical trial, requires a computer chip to be implanted in the motor cortex of the patient, which it then transmits to a computer for processing. Like all brain-computer interfaces, the user must train the software — but once this is done, you simply think of a movement, and the software moves the robot accordingly. Moving forward, the researchers would like to miniaturize the system and make it wireless — at the moment, BrainGate users have a box attached to their head, and they're tethered to a computer — which is OK for robot arm use at home, but obviously doesn't grant much mobility. The work was partly funded by DARPA, with the hope of creating more advanced prosthetics for wounded war veterans." This comes on the heels of a 71-year-old man regaining motor function in his fingers after doctors rewired his nerves to bypass the damaged ones.
