BBird writes "Deutsche Welle reports: 'Up until this year, preschools could teach and produce any kind of song they wanted. But now they have to pay for a license if they want children to sing certain songs. A tightening of copyright rules means kindergartens now have to pay fees to Germany's music licensing agency, GEMA, to use songs that they reproduce and perform. The organization has begun notifying creches and other daycare facilities that if they reproduce music to be sung or performed, they must pay for a license.'"

An article at Gamasutra takes an in-depth look at how Zynga's new browser-based social game CityVille managed to accumulate tens of millions of players in the relatively short time since its launch early this month. Quoting: "The Facebook interface induces a high degree of user blindness. It does not do a great job of exposing new games and applications, and lacks a directory or a 'Featured in the App Store' style of editorial (as Apple does for the iPhone), which means that for most developers there are huge problems in getting their games in front of users' eyeballs. With all of the free advertising channels on the platform now constrained or dead, this has meant that the Facebook economy has been acquiring an increasingly Darwinian shape. Where it used to be an egalitarian environment in which any developer could strike it big, over the last year it has become top-heavy with larger developers accruing exponential success, and cutting off oxygen to smaller companies by default."

arcticstoat writes "One of the barriers to the development of nanoscale electronics has potentially been eliminated, as scientists have discovered the world's smallest superconductor. Made up of four pairs of molecules, and measuring just 0.87nm, the superconductor could potentially be used as a nanoscale interconnect in electronic devices, but without the heat and power dissipation problems associated with standard metal conductors."

An anonymous reader writes "University of Michigan researchers have crammed an ARM Cortex microcontroller, a thin-film battery, and a solar cell into a package that is only 9 cubic millimeters in volume. The system is able to run perpetually by periodically recharging the on-board battery with a solar cell (neglecting physical wear-out of the system)."
