Spherical Projection, Sterling's Future, GNU Radio, and End-to-End Design

  1. Science on a Sphere — for when you want to see global data visualised without 2-D projection distortion.
  2. Lebowsky and Sterling’s 2016 State of the WorldThese physical barriers will suffer the “Fukushima effect:” the dikes you built to resist the tsunami only hold those catastrophic waters in, once the almighty wave comes over the top. Also, the industrial complex you are trying to protect from natural disaster becomes the source of a secondary, artificial disaster. (via BoingBoing)
  3. GNU Radio Tools for Radio Wrangling/Spectrum Domination (YouTube) — DEFCON talk.
  4. End-to-End Arguments in System Design (PDF) — End-to-end arguments are a kind of “Occam’s razor” when it comes to choosing the functions to be provided in a communication subsystem. Because the communication subsystem is frequently specified before applications that use the subsystem are known, the designer may be tempted to “help” the users by taking on more function than necessary. Awareness of end-to-end arguments can help to reduce such temptations.

Structured Image Concepts, Google's SDN, Lightbulb DeDRMing, and EFF SF

  1. Visual Genomea data set, a knowledge base, an ongoing effort to connect structured image concepts to language.
  2. Google’s Software Defined Networking[What was the biggest risk you faced rolling out the network? …] we were breaking the fate-sharing principle—which is to say we were putting ourselves in a situation where either the controller could fail without the switch failing, or the switch could fail without the controller failing. That generally leads to big problems in distributed computing, as many people learned the hard way once remote procedure calls became a dominant paradigm.
  3. Philips Backtrack on Lightbulb DRMIn view of the sentiment expressed by our customers, we have decided to reverse the software upgrade so that lights from other brands continue to work as they did before with the Philips Hue system.
  4. Pwning Tomorrow — EFF Publishes SF Anthology. You can expect liberties and freedoms to feature.
