A Worm Mind Forever LEGO Voyaging, Automatic Caption Generator, ELK Stack, and Amazonian Deployment

  1. A Worm’s Mind in a Lego Body — the c. elegans worm’s 302 neurons has been sequenced, modelled in open source code, and now hooked up to a Lego robot. It is claimed that the robot behaved in ways that are similar to observed C. elegans. Stimulation of the nose stopped forward motion. Touching the anterior and posterior touch sensors made the robot move forward and back accordingly. Stimulating the food sensor made the robot move forward. There is video.
  2. Show and Tell: A Neural Image Caption Generator — Google Research paper on generating captions like “Two pizzas sitting on top of a stove top oven” from a photo. Wow.
  3. Big Data with the ELK Stack — ElasticSearch, logstash, and Kibana. Interesting and powerful combination of tools!
  4. Apollo: Amazon’s Deployment EngineApollo will stripe the rolling update to simultaneously deploy to an equivalent number of hosts in each location. This keeps the fleet balanced and maximizes redundancy in the case of any unexpected events. When the fleet scales up to handle higher load, Apollo automatically installs the latest version of the software on the newly added hosts. Lust.
