Hugh Pickens writes "The city has always been an engine of intellectual life and the 'concentration of social interactions' is largely responsible for urban creativity and innovation. But now scientists are finding that being in an urban environment impairs our basic mental processes. After spending a few minutes on a crowded city street, the brain is less able to hold things in memory and suffers from reduced self-control. 'The mind is a limited machine,' says psychologist Marc Berman. 'And we're beginning to understand the different ways that a city can exceed those limitations.' Consider everything your brain has to keep track of as you walk down a busy city street. A city is so overstuffed with stimuli that we need to redirect our attention constantly so that we aren't distracted by irrelevant things. This sort of controlled perception — we are telling the mind what to pay attention to — takes energy and effort. Natural settings don't require the same amount of cognitive effort. A study at the University of Michigan found memory performance and attention spans improved by 20 percent after people spent an hour interacting with nature. 'It's not an accident that Central Park is in the middle of Manhattan,' says Berman. 'They needed to put a park there.'"

An anonymous reader writes "Next month, New Zealand is scheduled to implement Section 92 of the Copyright Amendment Act. The controversial act provides 'Guilt Upon Accusation,' which means that if a file-sharer is simply accused of copyright infringement he/she will be punished with summary Internet disconnection. Unlike most laws, this one has no appeal process and no punishment for false accusation, because they were removed after public consultation. The ISPs are up in arms and now artists are taking a stand for fair copyright."

marciot writes "It's interesting to look back at Ray Kurzweil's predictions for 2009 from a decade ago. He was dead on in predicting the ubiquity of portable computers, wireless, the emergency of digital objects, and the rise of privacy concerns. He was a little optimistic in certain areas, predicting the demise of rotating storage and the ubiquity of digital paper a bit earlier than it appears it will actually happen. On the topic of human-computer speech interfaces, though, he seems to be way off." And of course Kurzweil missed 9/11 and the fallout from that. His predictions might have been nearer the mark absent the war on terror.

An anonymous reader writes "The Milky Way is spinning much faster and has 50 per cent more mass than previously believed. This means the Milky Way is equivalent in size to our neighbor Andromeda — instead of being the little sister in the local galaxy group, as had been believed. One implication of this new finding is that we may collide with Andromeda sooner than we had thought, in 2 or 3 billion years instead of 5."

Ponca City, We love you writes "For thousands of years, losing teeth has been a routine part of human aging. Now the Washington Post reports that researchers are close to growing important parts of teeth from stem cells, including creating a living root from scratch, perhaps within one year. According to Pamela Robey of the NIH. 'Dentists say, "Give me a root and I can put a crown on it."' In a few years dentists will treat periodontal disease with regeneration by using stem cells to create hard and soft tissue; they will take out a tooth that is about to fall, and reconnect it firmly to the regenerated tissue. Although nobody is predicting when it will be possible to grow teeth on demand, in adults, to replace missing ones, a common guess is five to ten years. Baby and wisdom teeth are sources of stem cells that could be 'banked' for future health needs, says Robey. 'When you think about it, the teeth children put under their pillows may end up being worth much more than the tooth fairy's going rate. Plus, if you still have your wisdom teeth, it's nice to know you're walking around with your own source of stem cells.'"

CWmike writes "Amazon.com has rolled out a new option for its Simple Storage Service (S3) that lets data owners shift the cost of accessing their information to users. Until now, individuals or businesses with information stored on S3 had to pay data-transfer costs to Amazon when others made use of the information. Amazon said the new Requester Pays option relieves data providers of that burden, leaving them to pay only the basic storage fees for the cloud computing service. The bigger question with the cloud is, who really pays? Mark Everett Hall argues that IT workers do."

Hugh Pickens writes "BBC has an interesting article on the long-standing issue of how to power the 'climber' that would ascend a space elevator into space. Previous ideas have included delivering microwave or laser power to the climber beamed from the Earth's surface, but now European Space Agency ground station engineer Age-Raymond Riise has demonstrated a device that could provide a "lift into space" for cheaper space missions along a 100,000-km long tether anchored to the Earth. Riise demonstrated sending power mechanically by providing carefully timed jerks of the cable at its base with a broomstick to represent the cable held in tension, an electric sander to provide a rhythmic vibration to the bottom of the stick, and three brushes representing the climber with their bristles pointing downwards allowing the climber assembly to slide upward along the broomstick as it moved slightly downward, but grip it as it moved slightly upward. 'It would be possible to make a suspension system that completely decouples the cabin where the passengers are,' says Riise. 'For them it would be a linear movement with very little disturbance.' Riise says that he has been approached by commercial elevator companies, who are researching new ideas for elevators in superscrapers where the simplicity of the approach makes it attractive when compared to other ideas for powering lifts, such as compressed air."

surely_you_cant_be_serious writes "A nationwide survey finds that most companies consider their systems vulnerable to attack. Historically, crime rates increase during recessions — and some believe that cybercrime may well follow suit, especially given massive layoffs and the dim prospects many laid-off employees face in finding a new job. 'One thing companies can start doing is monitoring their networks on an ongoing basis so that they understand the normal pattern of data flow and usage, Brill said. In many cases, companies may not have the internal capability to do this, but outsourcing options are available. Kroll Ontrack, for instance, will be rolling out a 24/7 monitoring service for its global clients manned from a US location by professionals in early 2009.'"

An anonymous reader writes "Wired has the inside story of Max Butler, a former white hat hacker who joined the underground following a jail stint for hacking the Pentagon. His most ambitious hack was a hostile takeover of the major underground carding boards where stolen credit card and identity data are bought and sold. The attack made his own site, CardersMarket, the largest crime forum in the world, with 6,000 users. But it also made the feds determined to catch him, since one of the sites he hacked, DarkMarket.ws, was secretly a sting operation run by the FBI."

thepacketmaster writes "The Star reports about a new power generation model using smaller distributed power generators located closer to the consumer. This saves money on power generation lines and creates an infrastructure that can be more easily expanded with smaller incremental steps, compared to bigger centralized power generation projects. The generators in line for this are green sources, but Hyperion Power Generation, NuScale, Adams Atomic Engines (and some other companies) are offering small nuclear reactors to plug into this type of infrastructure. The generator from Hyperion is about the size of a garden shed, and uses older technology that is not capable of creating nuclear warheads, and supposedly self-regulating so it won't go critical. They envision burying reactors near the consumers for 5-10 years, digging them back up and recycling them. Since they are so low maintenance and self-contained, they are calling them nuclear batteries."

phyr writes "The European Space Agency (ESA) has released its Next ESA SAR Toolbox (NEST) freely as GPL for Linux and Windows. It provides an integrated viewer for reading, calibrating, post-processing and analysis of ESA (ERS 1&2, ENVISAT) and 3rd party (Radarsat2, TerraSarX, Alos Palsar, JERS) SAR level 1 data and higher. ESA has chosen to distribute the software as fully open source to allow the remote sensing community to easily develop new readers/writers and post-processors for SAR data with their NEST Java API. The software provides both a command line interface and GUI for all features including data conversion, graph processing, coregistration, multilooking, filtering, and band arithmetic."

Lorin Ricker writes "Back in the dark ages of windows-based GUIs, corresponding to my own wandering VMS evangelical days, I became enamored of a series of books jauntily entitled Xxx Annoyances (from O'Reilly & Assocs.), where "Xxx" could be anything from "Windows 95", "Word", "Excel" or nearly piece of software which Microsoft produced. These were, if not the first, certainly among the most successful of the "tips & tricks" books that have become popular and useful to scads of hobbyists, ordinary users, hackers and, yes, even professionals in various IT pursuits. I was attracted, even a bit addicted, to these if only because they offered to try to make some useful sense out of the bewildering design choices, deficiencies and bugs that I'd find rampant in Windows and its application repertory. Then I found Keir Thomas, who has been writing about Linux for more than a decade. His new "tips" book entitled, Ubuntu Kung Fu — Tips & Tools for Exploring Using, and Tuning Linux, and published by Pragmatic Bookshelf, is wonderful. Having only recently wandered into the light of Linux, open source software, and Ubuntu in particular, this book comes as a welcome infusion to my addiction." Read below for the rest of Lorin's review.

Anonymous Coward writes "A new method of DNA sequencing published this week in science identifies incorporation of single bases by fluorescence. This has been shown to increase read lengths from 20 bases (454 sequencing) to >4000 bases, with a 99.3% accuracy. Single molecule reading can reduce costs and increase the rate at which reads can be performed. 'So far, the team has built a chip housing 3000 ZMWs [waveguides], which the company hopes will hit the market in 2010. By 2013, it aims to squeeze a million ZMWs [waveguides] onto a single chip and observe DNA being assembled in each simultaneously. Company founder Stephen Turner estimates that such a chip would be able to sequence an entire human genome in under half an hour to 99.999 per cent accuracy for under $1000.'"

Na przykładzie przejścia praw autorskich do utworów Św. Faustyny (por. komentarze pod tekstem Prawa autorskie Siostry Faustyny) można pokazać kolejny problem domeny publicznej, a więc dostępność egzemplarzy, nośników, na których zapisano chronione wcześniej utwory. Poza egzemplarzami jest jeszcze inny problem, co kilka razy sygnalizowałem w tekstach na temat DRM - format danych, w jakim udostępnia się cyfrowo utwory w domenie publicznej. Przecież standard (techniczny) plików ma znaczenie dla ich dostępności i może się okazać, że chociaż utwory przeszły do domeny publicznej, to jednak istnieją nadal techniczne bariery w swobodnym korzystaniu z takich utworów.

DJAdapt writes to tell us that LG has launched a new line of high definition TVs that will be capable of streaming Netflix videos with no additional hardware. This is just another in a long line of expansions from the once DVD rental service, which has expanded to the Roku set top box, Xbox 360, PC, Mac, and Linux platforms recently. "Piping movies directly to TV sets is the natural evolution of the video streaming service, said Reed Hastings, the chief executive of Netflix. "The TV symbolizes the ultimate destination," he said. That idea -- shared by Sony Corp., which already streams feature films and TV shows directly to its Bravia televisions -- is still in its early stages. Netflix's streaming service taps a library of 12,000 titles, while the company's DVD menu numbers more than 100,000 titles. Hastings expects that gap will "definitely narrow" over time, but he noted that DVDs maintain an advantage over streaming, which is that "they are very profitable" for film studios."

nandemoari writes "It seems not even Microsoft is impervious to the effects of this increasingly painful recession. According to reports, the Redmond-based company is preparing to lay off about 17 per cent of its entire workforce in the coming months. Despite its portfolio diversity — including operating systems, antivirus software, and video game consoles — Microsoft is clearly feeling the pressure applied by a tightening global economy. In fact, there seems to be a sense of emergency to the massive cuts (about 15,000 workers out of 90,000), which rumors suggest should be made official by January 15."
