`bits.erl`

Function that takes a positive integer N and returns the sum of the bits in the binary representation. For example bits(7) is 3 and bits(8) is 1. Direct and tail-recurive versions.

`shapes.erl`

Calculates perimeter, area and enclosing rectangle for different types shape:

{ circle, { X, Y }, R }: circle (centre, radius)
{ rectangle, { X, Y }, W, H } rectangle (centre, width, height)

Installing RabbitMQ and the PHP PECL extension on Ubuntu 14.04 LTS

RabbitMQ apt repository

sudo add-apt-repository 'deb http://www.rabbitmq.com/debian/ testing main'
curl http://www.rabbitmq.com/rabbitmq-signing-key-public.asc | sudo apt-key add -
sudo apt-get update

RabbitMQ server and management plug-in

Very quick and dirty modification of Ben Pickles' minify, moving the actual minification to a web service in case you already have a minification workflow in place but don't want to install java on your development virtual machine.

You need Ruby, gems sinatra and closure-compiler (and thus Java) on the machine that hosts the web service.

Start the web service with

ruby app.rb

	{function, fibP, 1, 2}.
	{label,1}.
	{line,[{location,"adjacent.erl",4}]}.
	{func_info,{atom,adjacent},{atom,fibP},1}.
	{label,2}.
	{test,is_eq_exact,{f,3},[{x,0},{integer,0}]}.
	{move,{literal,{0,1}},{x,0}}.
	return.
	{label,3}.
	{allocate,0,1}.

	-module( pieces ).
	% I export fac and binomial so I can play in the shell.
	-export( [ fac/1, binomial/2, pieces/2, test2d/0, test3d/0 ] ).

	% Hopefully tail-recursive factorial. I’ve been reading ahead ;)
	fac( N ) ->
	fac( 1, N ).

	fac( Acc, 0 ) ->
	Acc;
