- Dark Web Site Taken Down without Breaking Encryption - Bruce Schneier comments on a report of the recent take down of a child-porn site that led to 337 arrests. The takedown was accomplished by sending small amounts - on the order of $100-$300 - to published bitcoin addresses, and watching that money flow through the distributed ledger until it landed in an identifiable location. Schneier points out, "Remember this the next time some law enforcement official tells us that they're powerless to investigate crime without breaking cryptography for everyone.".
- Video Friday: Kuka's Robutt Is a Robot Designed to Assess New Car Seats - IEEE Spectrum's weekly selection of awesome robot videos includes: Robutt, a robot that simulates thousands of human backsides for testing of automotive seat-cushions (I wonder if they remembered to place a wallet in the back pocket...); A robot constructed from a 3D printer that prints and uses its own mechanical components; Lockheed Martin's Onyx military grade exoskeleton that gives soldiers more strength and endurance; A biped that walks on "rough, uneven, or compliant surfaces"; A position-controlled quadruped that can walk and do flips without contact sensors; a demo video showing how drone operation can be improved by training on virtual drones before physical ones; a teaser video for NASA's Lucy mission; and more...
Here is my favorite - a robotic swarm algorithm for search & rescue, industrial and other purposes:
