PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

-E: will describe the underlaying queries of the \ commands (cool for learning!)
-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

Please note, data will be randomised until December 2014. It is based on Ipsos MORI's long term Issues Index survey 1974 - 2014.

Minimal example: transcode from MP3 to WMA:
ffmpeg -i input.mp3 output.wma

You can get the list of supported formats with:
ffmpeg -formats

You can get the list of installed codecs with:

	using System;
	using System.Net;

	namespace ConsoleApplication1
	{
	class Program
	{
	public class WebClientEx : WebClient
	{

	class Array
	def to_csv(csv_filename="hash.csv")
	require 'csv'
	CSV.open(csv_filename, "wb") do \|csv\|
	csv << first.keys # adds the attributes name on the first line
	self.each do \|hash\|
	csv << hash.values
	end
	end
	end

	require "csv"

	def csv_headers
	["Your", "Headers", "Here"]
	end

	files = Dir["file_names_*.csv"].sort_by { \|f\| "if you want to sort the files" }
	file_contents = files.map { \|f\| CSV.read(f) }

	csv_string = CSV.generate do \|csv\|

	# Too short methods lead to extraction of single-use methods, which can make
	# the code easier to read (by naming things), but can also clutter the class
