Global mutable state in erlang.
-module(horr).
-export([malloc/0, free/1, read/1, write/2, test/0]).
% You can use `malloc` to get a globally sharable, mutable cell of memory.
% A difference to C's `malloc` is that such a cell doesn't have a certain size (you can't overflow)
% Memory is initialised with the atom `null`.
malloc() ->
spawn(fun() -> mem(null) end).
% As processes are not garbage collected, you have to call `free` when you're done with your memory:

grunt-ember-templates plugin configuration for the Gruntfile + package.json. You'll have to update the Gruntfile with YOUR correct path to templates files. 1. Run `npm install` 2. Run `grunt` or `grunt watch`
module.exports = function(grunt) {
grunt.initConfig({
pkg: grunt.file.readJSON( 'package.json' ),
emberTemplates: {
compile: {

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.
