1,400 Megapixel Pan-STARRS Telescope Comes Online 54

ElectricSteve writes "Astronomers in Hawaii have announced they've successfully managed to boot up the Pan-STARRS (Panoramic Survey Telescope and Rapid Response System) telescope. Working from dusk to dawn every night, Pan-STARRS is able to map one-sixth of the sky each month, allowing astronomers to track all moving objects, calculate their orbits, and identify any potential threats to Earth. There are four Pan-STARRS cameras in total, each capable of capturing around 1.4 billion pixels over a sensor measuring 40 centimeters square. The focal plane of each camera contains an almost complete 64x64 array of CCD devices, each containing approximately 600x600 pixels, for a total resolution of 1.4 gigapixels."

Building Linux Applications With JavaScript 288

crankymonkey writes "The GNOME desktop environment could soon gain support for building and extending applications with JavaScript thanks to an experimental new project called Seed. Ars Technica has written a detailed tutorial about Seed with several code examples. The article demonstrates how to make a GTK+ application for Linux with JavaScript and explains how Seed could influence the future of GNOME development. In some ways, it's an evolution of the strategy that was pioneered long ago by GNU with embedded Scheme. Ars Technica concludes: 'The availability of a desktop-wide embeddable scripting language for application extension and plugin writing will enable users to add lots of rich new functionality to the environment. As this technology matures and it becomes more tightly integrated with other language frameworks such as Vala, it could change the way that GNOME programmers approach application development. JavaScript could be used as high-level glue for user interface manipulation and rapid prototyping while Vala or C are used for performance-sensitive tasks.'"

New Google Favicon Deja Vu All Over Again? 227

theodp writes "Last June, Google rolled out a new favicon, the small branding icon that graces your URL bar when you visit Google. Which, as it turned out, bore a striking similarity to Garth Brooks' Circle-G logo. Well, Google went back to the drawing board and has come back with a new favicon, which it says was inspired by — not copied from, mind you — its users' submitted ideas. Some are also seeing inspiration elsewhere for the new favicon, which consists of white 'g' on a background of four color swatches. Take the AVG antivirus icon, for instance. Or everybody's favorite memory toy, Simon. Or — in perhaps the unkindest cut of all — the four-color Microsoft Windows logo, shown here with a superimposed white '7'. Anything else come to mind?" What comes to mind for me is just how obsessed many people are with the Google favicon.

Groklaw Summarizes the Lori Drew Verdict 457

Bootsy Collins writes "Last Wednesday, the Lori Drew 'cyberbullying' case ended in three misdemeanor convictions under the Computer Fraud and Abuse Act, a 1986 US Federal law intended to address illegally accessing computer systems. The interpretation of the act by the Court to cover violations of website terms of service, a circumstance obviously not considered in the law's formulation and passage, may have profound effects on the intersection of the Internet and US law. Referring to an amicus curiae brief filed by online rights organizations and law professors, PJ at Groklaw breaks down the implications of the decision to support her assertion that 'unless this case is overturned, it is time to get off the Internet completely, because it will have become too risky to use a computer.'"

100x Denser Chips Possible With Plasmonic Nanolithography 117

Roland Piquepaille writes "According to the semiconductor industry, maskless nanolithography is a flexible nanofabrication technique which suffers from low throughput. But now, engineers at the University of California at Berkeley have developed a new approach that involves 'flying' an array of plasmonic lenses just 20 nanometers above a rotating surface, it is possible to increase throughput by several orders of magnitude. The 'flying head' they've created looks like the stylus on the arm of an old-fashioned LP turntable. With this technique, the researchers were able to create line patterns only 80 nanometers wide at speeds up to 12 meters per second. The lead researcher said that by using 'this plasmonic nanolithography, we will be able to make current microprocessors more than 10 times smaller, but far more powerful' and that 'it could lead to ultra-high density disks that can hold 10 to 100 times more data than today's disks.'"

New Plastic to Cut CO2 Emissions and Purify Water 120

Roland Piquepaille writes "Researchers have lots of imagination. After developing plastic as solid as steel, other scientists from in Australia, Korea and in the U.S. have created a plastic which could cut CO2 emissions and purify water. Their new material mimics pores found in plants and is exceptionally efficient. As said one of the lead researchers, 'it can separate carbon dioxide from natural gas a few hundred times faster than current plastic membranes and its performance is four times better in terms of purity of the separated gas.' Now it remains to be seen if commercial companies are interested, either for water desalination or for natural gas processing plants."

Melting Arctic Ice Has Consequences 466

OriginalArlen writes to tell us about some compelling global warming coverage in the Washington Post. First there is an article about a study indicating that melting Arctic ice is threatening polar bears with extinction. The article quotes an environmentalist: "This study is the smoking gun. Skeptics, polluting industries and President Bush can't run away from this one." And the polar melting is opening new shipping lanes. The second article details a trip late in October through the Northwest Passage by a Canadian icebreaker. Never before in history could this trip have been accomplished so late in the year; ice would have choked off the passage. Estimates of when the passage might be navigable by commercial shipping range from 2020 to the end of the century. The indigeneous people are not looking forward to this development.

Publishers Thank Google for Book Sales 257

eldavojohn writes "A few book publishers are actually thanking Google for an apparent rise in sales due to Google's scan plan. Google is busy defending itself against authors and publishers that have brought lawsuits for ignoring copyrights. The director of the Oxford University Press said, 'Google Book Search has helped us turn searchers into consumers.' It seems to work in favor of the smaller publishers: 'Walter de Gruyter/Mouton-De Gruyter, a German publisher, said its encyclopedia of fairy tales has been viewed 471 times since appearing in the program, with 44 percent of them clicking on the 'buy this book' Google link.' Do you think that Google's 'sneak peak' search access increases sales or violates copyrights on intellectual property?"

Stolen Cell Phone Shares Thieves' Photos? 133

eastbayted writes "A man from Berkeley, Calif. had his cell phone swiped. Soon after, the ShoZu starting uploading pictures to his Flickr account taken by the thieves — for the world to see. There's one of an unidentified woman eating something chocolatey, and a couple of either a chihuahua or a large rat. Seems this guy had installed some software on his phone to automatically perform those photo uploads, and whoever took his phone didn't realize it That's his story, anyway ... some people doubt it. He's a Yahoo employee. Yahoo owns Flickr. This is all pretty good PR for the photo site, no? He claims: 'People assume I'm doing it for self-promotion, marketing, a hoax or something like that. I'm talking to you because I want it to be known that it's not a hoax. I'm just too ordinary. I'm just too unclever for that.'" Update: 09/02 05:48 GMT by Z : Made the quote more obvious.

Comment Re:Use Epiphany (Score 1) 394

Epiphany may be snappier, but it's "innovative" bookmarks make it useless for me. I have lots of bookmarks, arranged in hierarchical folders, with order set by hand, that roughly reflects my preferences and frequency of visits (say, a most frequently visited source of information for Python would be at the top of the Python folder in a Programming folder). Epiphany authors think they know better and do not allow me to create nested folders or arrange bookmarks in other than alphabetical order.

Scientists Find Brain Cells Linked to Choice 279

An anonymous reader writes "Scotsman.com is reporting that Harvard Medical researchers may have found the neurons, or brain cells, that play a role in a persons ability to choose between different items. From the article: 'Scientists have known that cells in different parts of the brain react to attributes such as color, taste or quantity. Dr Camillo Padaoa-Schioppa and John Assad, an associate professor of neurobiology, found neurons involved in assigning values that help people to make choices.'"

Dvorak Avocates Open Sourcing OS X 571

xzvf writes "Dvorak claims OS X and Apple in trouble. He suggests open sourcing OS X for an epic battle with Linux. In many ways, this is just insane rambling, but it's certainly entertaining on some levels." From the article: "That would make the battle between OS X and Linux the most interesting one on the computer scene. With all attention turned in that direction, there would be nothing Microsoft could do to stem a reversal of its fortunes. Let's start at the beginning. There's been a lot of fuss over Apple's rollout of the unsupported Boot Camp product, which lets Mac users run Microsoft Windows easily on an Intel-based Macintosh. I got into various levels of trouble when I suggested that Apple was going to gravitate towards Windows since it would be easy to do and there was some evidence that the company might want to do it."
