/. geekdreams writes “Brad Fitzpatrick, the founder of LiveJournal, has launched OpenID, an ‘actually distributed identity system’ for websites that accept user comments. The system utilizes decentralized servers to authenticate users, and aims to replace centralized ID systems such as Microsoft’s Passport and SixApart’s TypeKey. The first implementation of OpenID can be seen on LiveJournal comments pages.” Previously mentioned on Slashdot, now out of development.

chromatic writes “A constant question for software developers is ‘What is the nature of programming?’ Is it art or science? Does creativity or engineering lead the design and implementation of a program? John Littler talked to several well-known and well-respected programmers (including Guido van Rossum, Andy Hunt, Bjarne Stroustrup, Paul Graham, and Richard Stallman) to find their answers; he shares their thoughts and his own in Art and Computer Programming.” From the article: “What the heck is art anyway, at least as most people understand it? What do people mean when they say ‘art’? A straw poll showed a fair degree of consensus–art is craft plus a special degree of inspiration. This pretty much explains immediately why only art students and art critics at a certain sort of paper favor conceptual art. Conceptual art, of course, often lacks a craft component as people usually understand the term.”

/. Ryan MacCarthy writes “When Google and Yahoo
released their map API’s last week they unleashed a horde of hungry developers eager to integrate their data with the user-friendly maps. Brilliant hacks like Chicago Crime and Craigslist Real Estate are in the midst of switching over to the new API, while sites like MetroFreeFi use the new API to make it easier to find free wi-fi locations in US cities (San Francisco, for example). Imaginative developers, like Alan Taylor (Transparency concept), are digging deep into experimentation to dream up new uses for the maps. It’s great to see the innovation when hacks turn to apps.” I want to see Los Angeles maps of the action in James Ellroy’s novels, and a national map of the worst, funniest tourist traps across the U.S.

mopslik writes “OSNews has an interesting editorial discussing why smaller operating systems will have a hard time gaining popularity. Familiarity, developer participation, and market saturation are listed as reasons for failure. Although the article focuses mainly on Syllable and SkyOS, I’m sure there are countless other operating systems to which these arguments apply.”

/. james tech writes “The Virgo Consortium recently completed its massive “Millennium Simulation”, tracing the universe’s evolution from its early origins to present day. To simplify the computations, they considered only dark matter which composes most of the universe. Using a 512-node cluster with IBM
processors, the group produced over 20 terabytes of data with some of the most breathtaking images of the universe never seen. A visible matter simulation is underway, at a lower resolution.”
