Four short links: 7 December 2012

AR Drone That Infects Other Drones With Virus Wins DroneGames (IEEE) — how awesome is a contest where a group who taught a drone to behave itself on the end of a leash, constantly taking pictures and performing facial recognition, posting the resulting images to Twitter in real-time didn’t win.
BitCoin-Central Becomes Legit Bank — After all this patient work and lobbying we’re finally happy and proud to announce that Bitcoin-Central.net becomes today the first Bitcoin exchange operating within the framework of European regulations. Covered by FDIC-equivalent, can have debit or credit cards connected to the BitCoin account, can even get your salary auto-deposited into your BitCoin account.
The Antifragility of the Web (Kevin Marks) — By shielding people from the complexities of the web, by removing the fragility of links, we’re actually making things worse. We’re creating a fragility debt. Suddenly, something changes – money runs out, a pivot is declared, an aquihire happens, and the pent-up fragility is resolved in a Black Swan moment.
