At the heart of our technological age are people who call themselves hackers. Define themselves as people who are dedicated to program so passionate and believe that it is a duty for them to share information and develop free software. We must not confuse them with crackers, destructive users whose aim is to create virus and introduced in other systems: a hacker is an expert or enthusiast of any kind which may engage or not to computing. In this sense, the hacker ethic is a moral challenge to the protestant ethic of work, as Max Weber described it in his classic, The Protestant Ethic and the Spirit of Capitalism, which is based on diligent work, the acceptance of routine, the value of money and concern for the income. Confronting this morality, the ethic of work for the hacker is based on the value of creativity, passion and freedom. Money ceases to be a value in itself and the benefit is estimated at targets such as the social value and free access, transparency and openness. This book is an invitation to explore the fundamental questions about life in the information society, to undertake a journey full of surprises that will help us steer our lives into new and exciting prospects.
