An anonymous reader writes "It seems that the most recent DVDs released by Sony — specifically Stranger Than Fiction, Casino Royale, and The Pursuit of Happyness — have some kind of 'feature' that makes them unplayable on many DVD players. This doesn't appear to be covered by the major media yet, but this link to a discussion over at Amazon gives a flavor of the problems people are experiencing. A blogger called Sony and was told the problem is with the new copy protection scheme, and they do not intend to fix it. Sony says it's up to the manufacturers to update their hardware."

Remember the hexagon surrounding Saturn's north pole? Now for our delectation Ano_Nimass Coward sends us to Space.com for a look at a nebula with near perfect bilateral symmetry surrounding a dying star. The so-called Red Square ranks among the most symmetrical objects ever observed by scientists. "If you fold things across the principle diagonal axis, you get an almost perfect reflection symmetry," said the leader of a study of the object, recently published in Science. A possible explanation for the structure's glow, if not its shape, was advanced in a paper appearing in PNAS, which attributes the glow of a similar object — dubbed, confusingly, the Red Rectangle — to exotic space-hardened organic molecules called Polycyclic Aromatic Hydrocarbons. PAHs are normally unstable but may occur in places like the nebula in question, in nanostructured clusters that are extremely stable and radiation hardened.

Ashley Gittins writes "Users of the popular accounting package SQL-Ledger were being kept in the dark about a recent license change. Two weeks ago a new version of the software was released but along with it came the silent change of license from GPLv2 to the 'SQL-Ledger Open Source License' — presumably in an effort to prevent future forks like LedgerSMB. As it turns out, the author was making deliberate attempts to prevent the community from finding out about the license change. No posts to the SQL-Ledger mailing lists asking about the license change were getting past moderation and direct questions to the author were going unanswered. Just recently the license was switched back to GPLv2. This behavior is not a first for this particular project, and is part of the reason for the original LedgerSMB fork. Does a project maintainer have an ethical obligation to notify his or her community of a license change? What about a legal obligation?"

An anonymous reader writes "Microsoft says there are over 1,000 applications you can run on Windows Vista with few, if any, issues. However, Windows apps number in the tens of thousands. Add to that the facts that x64 Vista versions don't support legacy 16-bit code, and that the Windows Resource Protection in Vista breaks some apps, and you've got a big issue. InformationWeek lists a host of workarounds in How To Manage Windows Vista Application Compatibility. Among the tips discussed are Vista's compatibility mode, its Program Compatibility Assistant wizard, and a little-known form of file and registry virtualization that's built into the OS. What problems have you encountered with incompatible apps, and are any issues you've encountered deal-breakers that could further roil the already muddied adoption picture for Vista?"

marto writes "All over Europe thousands of people are being threatened with court action for allegedly sharing games like Dream Pinball 3D on P2P networks. Now, documents obtained by TorrentFreak show details of the anti-piracy company's techniques for identifying alleged file-sharers on the internet and the gathering of claimed 'forensic quality' evidence for use in court cases."

A trio of teams have banded together to succeed in the 'FIRST Robotics Competition'. The teams Bobcat Robotics from South Windsor, Connecticut, Highrollers from Las Vegas, Nevada, and Gompei and the HERD from Worcester, Massachusetts combined to create a versatile robot geared to succeeding at a number of odd tasks. "These young people had six weeks to perfect their machines. And they had the enthusiasm of any athletic competition. From tie-dyed shirts to human hair dyed in school colors, competitors from 23 countries showed that math, science and brains can provide a lot of excitement ... Whether it is computer programming, wiring a motor or scouting rivals to develop strategy, students said the skills they develop often go beyond the contest. Clearly, the event has piqued the interest of major sponsors such as NASA, which will broadcast webcasts of the competitions."
