MojoKid writes "As you wait in the checkout line for the holidays, your observation is most likely correct. That other line is moving faster than yours. That's what Bill Hammack (the Engineer Guy), from the Department of Chemical and Biomolecular Engineering at the University of Illinois — Urbana proves in this video. Ironically, the most efficient set-up is to have one line feed into several cashiers. This is because if any one line slows because of an issue, the entry queue continues to have customers reach check-out optimally. However, this is also perceived by customers as the least efficient, psychologically."

DarkKnightRadick writes "An undergrad student at the University of Utrecht, Marianne Heida, has found evidence of a supermassive black hole being tossed out of its galaxy. According to the article, the black hole — which has a mass equivalent to one billion suns — is possibly the culmination of two galaxies merging (or colliding, depending on how you like to look at it) and their black holes merging, creating one supermassive beast. The black hole was found using the Chandra Source Catalog (from the Chandra X-Ray Observatory). The direction of the expulsion is also possibly indicative of the direction of rotation of the two black holes as they circled each other before merging."

timholman writes "According to Gizmodo, an investigation has shown that the $399 OpenMac is almost certainly vaporware, as is Psystar itself. The company's address has actually changed twice this week, according to its web page, and Psystar is no longer accepting credit card transactions. Too bad for those who may have already ordered an OpenMac."

atbarboz writes "One of the first converts to Oracle's support for Linux said it has endured a public backlash since its decision to drop Red Hat. 'Melbourne company Opes Prime Stockbroking told ZDNet Australia that in the weeks following its announcement to adopt Oracle Linux, upset Linux enthusiasts phoned, e-mailed and wrote about the company online to complain at the decision. "People called us out of the blue to tell us we were idiots," said Opes executive director Anthony Blumberg.'"

mstaj noted that Bill Gates has an article in January edition of Scientific American A Robot in Every Home."Imagine being present at the birth of a new industry. It is an industry based on groundbreaking new technologies, wherein a handful of well-established corporations sell highly specialized devices for business use and a fast-growing number of start-up companies produce innovative toys, gadgets for hobbyists and other interesting niche products. But it is also a highly fragmented industry with few common standards or platforms. Projects are complex, progress is slow, and practical applications are relatively rare. In fact, for all the excitement and promise, no one can say with any certainty when — or even if — this industry will achieve critical mass. If it does, though, it may well change the world."

An anonymous reader writes "CNN tells us that today's young adults are no longer excited at the possibility of space exploration: 'The 2004 and 2006 surveys by Dittmar Associates Inc. revealed high levels of indifference among 18- to 25-year-olds toward manned trips to the moon and Mars. The space shuttle program is slated to end in 2010 after construction of the international space station is completed with 13 more shuttle flights. The recent 13-day mission by Discovery's seven astronauts was part of that long-running construction job.' As a result, NASA's budget will include a greater amount of public relations spending."

An anonymous reader writes "The Times of London has an article on how Garry Kasparov, former world chess champion, is using his fame and intellect in an attempt to defeat President Putin at the presidential elections in March 2008. Kasparov believes that Putin is virtually a dictator who is dismantling democracy and returning Russia to an authoritarian regime. Some high-profile Putin critics, such as Alexander Litvinenko, have been the victims of unsolved murders, and Kasparov is aware of the dangers: 'I can calculate the possibilities as a chess player and I have to be honest and say that our chances are not high. But I take this as a moral duty, and when you do something out of moral duty, then who cares?'" From the article: "[Kasparov] will not be a contender for the presidency but [his political umbrella group] The Other Russia aims to create the conditions under which an anti-Putin candidate can win. It appears, however, to be an uneven contest against a man who enjoys 80 per cent approval ratings. Most Russians want Mr. Putin to overturn a constitutional bar on a third term in office. Many will back whomever Mr. Putin endorses to succeed him."

An anonymous reader writes "Ever wondered, how P2P software like Skype directly exchanges data — despite the fact, that both machines are sitting behind a firewall that only permits outgoing traffic? Read about the hole punching techniques, that make a firewall admin's nightmares come true."

Maxx writes to mention a ZDNet article about Microsoft's dictum on Vista as a virtual machine. The software giant has declared that home versions of their upcoming OS may not be run virtually, because 'virtualization is not mature enough for broad adoption.' From the article: "'Microsoft says that consumers don't understand the risks of running virtual machines, and they only want enterprises that understand the risks to run Vista on a VM. So, Microsoft removes user choice in the name of security,' says Gartner analyst Michael Silver. 'The other option is to pay Microsoft US$300 for Windows Vista Business or US$399 for Windows Ultimate, instead of US$200 for Home Basic or US$239 for Home Premium,' Silver suggested."

prostoalex writes "Encryption guru Bruce Schneier takes a look at perceived and actual risks with some insightful commentary on how warped the public perception of risks may be: '...we worry more about anthrax (with an annual death toll of roughly zero) than influenza (with an annual death toll of a quarter-million to a half-million people). Influenza is a natural accident, anthrax is an intentional action, and the smallest action captures our attention in a way that the largest accident doesn't. If two airplanes had been hit by lightning and crashed into a New York skyscraper, few of us would be able to name the date on which it happened.'"
