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

// Read Stefan's excellent paper for details on how this code works.

Business models based on the compiled list at http://news.ycombinator.com/item?id=4924647. I find the link very hard to browse, so I made a simple version in Markdown instead.

An example of using Make instead of Grunt for fast, simple and maintainable front-end asset compilation.
# A simple Makefile alternative to using Grunt for your static asset compilation
#
## Usage
#
# $ npm install
#
# And then you can run various commands:
#
# $ make # compile files that need compiling
# $ make clean all # remove target files and recompile from scratch
