What did I learn this week (2021) - 21

  1. Read a nice book about UX design tips written by Victor. It is a collection of tweets than a book, but very helpful.
  2. Learned about Cognitive Load.
  3. Found a Teach Yourself Demoscene repository. I haven't heard about this before. The demoscene is an international computer art subculture focused on producing demos: self-contained, sometimes extremely small, computer programs that produce audiovisual presentations.
  4. China uses a different geographic coordinate system than the rest of the world. WGS-84 is the most common coordinate system, but China uses GCJ-02, sometimes called Mars Coordinates. Part of GCJ-02 is an algorithm that obfuscates the results. So applying any GCJ-02 coordinate to a globe using WGS-84 coordinates gets distorted like a funhouse mirror. Found this info in HN.
  5. Project Starline is an experimental video communication method currently in development by Google that allows the user to see a 3D model of the person they are communicating with. My first thought was that it looks like how people communicate with inmates in US prisons.
