Four short links.
  1. A Bug Detective Story — spoiler: the CPU did it.
  2. How to Capture Videos of Brains in Real TimeThe scientists first engineered the animals’ neurons to fluoresce (glow), using a method called optogenetics. The stronger the neural signal, the brighter the cells shine. To capture this activity, they used a technique known as “light-field microscopy,” in which an array of lenses generates views from a variety of perspectives. These images are then combined to create a three-dimensional rendering, using a new algorithm called “seeded iterative demixing” (SID) developed by the team.

  4. Lacuna — open source collaborative annotation for tertiary classes, built at Stanford.
  5. The .feedback Scam — wow. An entire top-level domain dedicated to the old “someone is talking about you, sign up to find out what they’re saying” scam.
