DARPA Robotics Challenge, Math Instruction, Microservices Construction, and Crypto Hardware Sans Spooks

  1. Pocket Guide to DARPA Robotics Challenge Finals (Robohub) — The robots will start in a vehicle, drive to a simulated disaster building, and then they’ll have to open doors, walk on rubble, and use tools. Finally, they’ll have to climb a flight of stairs. The fastest team with the same amount of points for completing tasks will win. The main issues teams will face are communications with their robot and battery life: “Even the best batteries are still roughly 10 times less energy-dense than the kinds of fuels we all use to get around,” said Pratt.
  2. Dan Meyer’s Dissertation — Dan came up with a way to make math class social and the vocabulary sticky.
  3. Monolith First — echoes the idea that platforms should come from successful apps (the way AWS emerged from operating the Amazon store) rather than be designed before use.
  4. Building a More Assured Hardware Security Module (PDF) — proposal for An open source reference design for HSMs; Scalable, first cut in an FPGA and CPU, later allow higher speed options; Composable, e.g. “Give me a key store and signer suitable for DNSsec”; Reasonable assurance by being open, diverse design team, and an increasingly assured tool-chain.
