From the Internet's infrastructure to operating systems like GNU/Linux, the open source movement comprises some of the greatest accomplishments in computing over the past quarter century. Its story embraces technological advances, unprecedented global collaboration, and remarkable tools for facilitating distributed development. The evolution of the Internet enabled an enormous expansion of open development, allowing developers to exchange information and ideas without regard to constraints of space, time, or national boundary. The movement has had widespread impact on education and government, as well as historic cultural and commercial repercussions. Part I discusses key open source applications, platforms, and technologies used in open development. Part II explores social issues ranging from demographics and psychology to legal and economic matters. Part III discusses the Free Software Foundation, open source in the public sector (government and education), and future prospects.

Much of the innovative programming that powers the Internet, creates operating systems, and produces software is the result of “open source” code, that is, code that is freely distributed—as opposed to being kept secret—by those who write it. Leaving source code open has generated some of the most sophisticated developments in computer technology, including, most notably, Linux and Apache, which pose a significant challenge to Microsoft in the marketplace. As Steven Weber discusses, open source’s success in a highly competitive industry has subverted many assumptions about how businesses are run, and how intellectual products are created and protected.Traditionally, intellectual property law has allowed companies to control knowledge and has guarded the rights of the innovator, at the expense of industry-wide cooperation. In turn, engineers of new software code are richly rewarded; but, as Weber shows, in spite of the conventional wisdom that innovation is driven by the promise of individual and corporate wealth, ensuring the free distribution of code among computer programmers can empower a more effective process for building intellectual products. In the case of Open Source, independent programmers—sometimes hundreds or thousands of them—make unpaid contributions to software that develops organically, through trial and error.Weber argues that the success of open source is not a freakish exception to economic principles. The open source community is guided by standards, rules, decisionmaking procedures, and sanctioning mechanisms. Weber explains the political and economic dynamics of this mysterious but important market development.

In Open Source Jihad, Per-Erik Nilsson provides a unique overview of the academic research and political legislation concerning 'Islamic terrorism' in Europe. He scrutinises in detail how the concepts 'terrorism', 'radicalisation', and 'counter-terrorism' have developed as academic objects of study and political objects of governance. In the Element, Nilsson brings to the fore systemic problems of the field of terrorism studies as well as the various anti-terrorist apparatuses developed by EU member states. Open Source Jihad should be required reading for anyone interested in current European political and social events.

In recent years, the way open source software is developed has taken hold as a valid alternative to commercial proprietary methods, as have the products themselves, e.g., the Linux operating system, Apache web-server software, and Mozilla Firefox browser. But what is open source software? How is the open source community organized? What makes this new model successful? What effects has it had and might it have on the future of the IT industry, companies and government policies? These and many other questions are answered in this book.The first chapter gives a brief history of the open source community and the second chapter takes a close look at the relationship between intellectual property rights and software, both open source and proprietary. The next three chapters consider the who, the open source community, the how, software development both within and outside the community, and the what, open source projects and product quality. Chapters 6 and 7 focus on the different users of open source software: companies and governments respectively. These are followed by two chapters that interpret the phenomenon, first from an organizational point of view in Chapter 8 and then using the theory of complex adaptive systems in Chapter 9. The last chapter explores the current and potential applications of the concept underlying open source software in other fields.

Open source software licences are based on two fundamental principles: the possibility for users to use the software for any purpose and the possibility to modify and redistribute it without prior authorisation from the initial developer. Some open source software licences, like the General Public Licence (GPL), also impose a corollary obligation on the licensee: to make the source code available to other developers. The idea behind this form of licensing is that when programmers can read, redistribute and modify the source code for a piece of software, the software evolves.A number of legal challenges need to be addressed in order to ensure the most efficient deployment of open contentlicences in Europe and in the Netherlands, not least because most open source licences originate from the United States. This study gives an overview of the current legal situation regarding the use of open source software licences and investigates how the most commonly used open source software licences measure up to Dutch and European law. How does the distinct production and distribution model of open source licences fit in the current legal framework? Does the current legal environment support the use of open source licences or does it rather impede their use? In this last case, would certain adaptations to the law or to the licence terms be appropriate?By its in-depth analysis and clear conclusions, Unravelling the Myth around Open Source Licences amply contributes to the understanding of this complex field that policy makers, regulators, and academics so crucially require. Taking the provisions of the GNU GPL, the BSD, and the Mozilla Public Licence as examples, it investigates the implications of open source licensing from a private law, copyright law and patent law perspective. It also takes a brief look at the issue of the enforcement of these licences. To facilitate the use and enforcement of open source software licences in Europe, and more particularly in the Netherlands, the authors conclude their study by making a number of recommendations for the adaptation of the licence terms with a view to enhancing their compliance with the legal requirements.Lucie Guibault is Senior Researcher at the University of Amsterdam’s Institute for Information Law (IViR).

Modern science is ever more driven by computations and simulations. In particular, the state of the art in space and Earth science often arises from complex simulations of climate, space weather, and astronomical phenomena. At the same time, scientific work requires data processing, presentation, and analysis through broadly available proprietary and community software.1 Implicitly or explicitly, software is central to science. Scientific discovery, understanding, validation, and interpretation are all enhanced by access to the source code of the software used by scientists.This report investigates and recommends options for NASA's Science Mission Directorate (SMD) as it considers how to establish a policy regarding open source software to complement its existing policy on open data. In particular, the report reviews existing data and software policies and the lessons learned from the implementation of those policies, summarizes community perspectives, and presents policy options and recommendations for implementing an open source software policy for NASA SMD.
