Four short links: 24 December 2013

  1. Arduino Robot — for all your hacking needs.
  2. LIDAR for Smartphones (DIYdrones) — The device attaches to the back of a smartphone and combines a built-in laser range finder, 3D compass and Bluetooth chip with the phone’s camera and GPS.
  3. Bridge Inspection Robot Equipping Magnets — 7.8 inches/second, magnets, can scuttle up walls and along ceilings.
  4. OpenEmu — nice-looking emulator framework for OS X. Make your Christmas present a trip back in time.

Four short links: 28 October 2013

  1. A Cyber Attack Against Israel Shut Down a RoadThe hackers targeted the Tunnels’ camera system which put the roadway into an immediate lockdown mode, shutting it down for twenty minutes. The next day the attackers managed to break in for even longer during the heavy morning rush hour, shutting the entire system for eight hours. Because all that is digital melts into code, and code is an unsolved problem.
  2. Random Decision Forests (PDF) — “Due to the nature of the algorithm, most Random Decision Forest implementations provide an extraordinary amount of information about the final state of the classifier and how it derived from the training data.” (via Greg Borenstein)
  3. BITalino — 149 Euro microcontroller board full of physiological sensors: muscles, skin conductivity, light, acceleration, and heartbeat. A platform for healthcare hardware hacking?
  4. How to Be a Programmer — a braindump from a guru.

  1. Researchers Can Slip an Undetectable Trojan into Intel’s Ivy Bridge CPUs (Ars Technica) — The exploit works by severely reducing the amount of entropy the RNG normally uses, from 128 bits to 32 bits. The hack is similar to stacking a deck of cards during a game of Bridge. Keys generated with an altered chip would be so predictable an adversary could guess them with little time or effort required. The severely weakened RNG isn’t detected by any of the “Built-In Self-Tests” required for the P800-90 and FIPS 140-2 compliance certifications mandated by the National Institute of Standards and Technology.
  2. rethinkdbopen-source distributed JSON document database with a pleasant and powerful query language.
  3. Teach Kids Programming — a collection of resources. I start on Scratch much sooner, and 12+ definitely need the Arduino, but generally I agree with the things I recognise, and have a few to research …
  4. Raspberry Pi as Ad-Blocking Access Point (AdaFruit) — functionality sadly lacking from my off-the-shelf AP.
