Flying Robot, State of Cyberspace, H.264, and Principal Component Analysis

  1. Insect-Inspired Collision-Resistant Robot — clever hack to make it stable despite bouncing off things.
  2. The Battle for Power on the Internet (Bruce Schneier) — the state of cyberspace. [M]ost of the time, a new technology benefits the nimble first. […] In other words, there will be an increasing time period during which nimble distributed powers can make use of new technologies before slow institutional powers can make better use of those technologies.
  3. Cisco’s H.264 Good News (Brendan Eich) — Cisco is paying the license fees for a particular implementation of H.264 to be used in open source software, enabling it to be the basis of web streaming video across all browsers (even the open source ones). It’s not as ideal a solution as it might sound.
  4. Principal Component Analysis for DummiesThis post will give a very broad overview of PCA, describing eigenvectors and eigenvalues (which you need to know about to understand it) and showing how you can reduce the dimensions of data using PCA. As I said it’s a neat tool to use in information theory, and even though the maths is a bit complicated, you only need to get a broad idea of what’s going on to be able to use it effectively.

    I am huge fan of Brendan Eich. Like to subscribe him but won’t find him on twitter.
