How to create a double-click-to-start web server

How to create a double-click-to-start web server

  1. Download the "Start HTTP Server Here.command" file
    • In Safari you can do that by ⌥ (option) clicking the "raw" link next to that script.
  2. Add the executable flag
    so that it will run when you double-click it
    • type chmod +x "$HOME/Downloads/Start HTTP Server Here.command"
  3. Move the command file into the root folder of your website
  4. Double-click it to start your webserver.
    Your browser will load it up automatically

two Perlin noise generators in javascript. The simplex version is about 10% faster (in Chrome at least, haven't tried other browsers)
// Ported from Stefan Gustavson's java implementation
// http://staffwww.itn.liu.se/~stegu/simplexnoise/simplexnoise.pdf
// Read Stefan's excellent paper for details on how this code works.
