The rise of open source licensing : a challenge to the use of intellectual property in the software industry

Open source software – from Linux to Firefox and MySQL database – has changed software business as we knew it. New start-ups have challenged industry heavyweights from Microsoft to Oracle with innovative copyright licensing strategies and courageous anti-patent policies. Almost every major software company has been forced to react to the commodification trend. The overall argument of the book is that open source licensing has indeed changed the ways the software industry thinks of and actually uses intellectual property. The thesis further argues that the implications of open source to the management of intellectual property are twofold. First, intellectual property infringement risks must be taken more seriously when open source software is used. This is because open source increases the negative effects from the continuous expansion of intellectual property rights. Second, "Internet-businesses" are finally breaking through into software markets. This means that the value of intellectual property increases from sharing but also becomes more complex to appropriate. Finally, this book argues that open source can have relevant implications on intellectual property rights policy. First, openness balances commercial regulation. Open licensing systems have proved how potential drawbacks from overregulation can be fixed without state intervention. Second, open source also emphasizes a more material study of intellectual property rights. When a substantial number of right holders in a given industry decide not to enforce their core intellectual property rights – relying on economic-rational arguments – the premises of the policy discussion can be seen in a new light.reviewe

Using MapReduce Streaming for Distributed Life Simulation on the Cloud

Distributed software simulations are indispensable in the study of large-scale life models but often require the use of technically complex lower-level distributed computing frameworks, such as MPI. We propose to overcome the complexity challenge by applying the emerging MapReduce (MR) model to distributed life simulations and by running such simulations on the cloud. Technically, we design optimized MR streaming algorithms for discrete and continuous versions of Conway’s life according to a general MR streaming pattern. We chose life because it is simple enough as a testbed for MR’s applicability to a-life simulations and general enough to make our results applicable to various lattice-based a-life models. We implement and empirically evaluate our algorithms’ performance on Amazon’s Elastic MR cloud. Our experiments demonstrate that a single MR optimization technique called strip partitioning can reduce the execution time of continuous life simulations by 64%. To the best of our knowledge, we are the first to propose and evaluate MR streaming algorithms for lattice-based simulations. Our algorithms can serve as prototypes in the development of novel MR simulation algorithms for large-scale lattice-based a-life models.https://digitalcommons.chapman.edu/scs_books/1014/thumbnail.jp

An introduction to the Philosophy of Information

This book serves as the main reference for an undergraduate course on Philosophy of Information. The book is written to be accessible to the typical undergraduate student of Philosophy and does not require propaedeutic courses in Logic, Epistemology or Ethics. Each chapter includes a rich collection of references for the student interested in furthering her understanding of the topics reviewed in the book. The book covers all the main topics of the Philosophy of Information and it should be considered an overview and not a comprehensive, in-depth analysis of a philosophical area. As a consequence, 'The Philosophy of Information: a Simple Introduction' does not contain research material as it is not aimed at graduate students or researchers
