Freely available source code, with contributions from thousands of programmers around the world: this is the spirit of the software revolution known as Open Source. Open Source has grabbed the computer industry's attention. Netscape has opened the source code to Mozilla; IBM supports Apache; major database vendors haved ported their products to Linux. As enterprises realize the power of the open-source development model, Open Source is becoming a viable mainstream alternative to commercial software.Now in Open Sources, leaders of Open Source come together for the first time to discuss the new vision of the software industry they have created. The essays in this volume offer insight into how the Open Source movement works, why it succeeds, and where it is going.For programmers who have labored on open-source projects, Open Sources is the new gospel: a powerful vision from the movement's spiritual leaders. For businesses integrating open-source software into their enterprise, Open Sources reveals the mysteries of how open development builds better software, and how businesses can leverage freely available software for a competitive business advantage.The contributors here have been the leaders in the open-source arena: Brian Behlendorf (Apache) Kirk McKusick (Berkeley Unix) Tim O'Reilly (Publisher, O'Reilly & Associates) Bruce Perens (Debian Project, Open Source Initiative) Tom Paquin and Jim Hamerly (mozilla.org, Netscape) Eric Raymond (Open Source Initiative) Richard Stallman (GNU, Free Software Foundation, Emacs) Michael Tiemann (Cygnus Solutions) Linus Torvalds (Linux) Paul Vixie (Bind) Larry Wall (Perl) This book explains why the majority of the Internet's servers use open- source technologies for everything from the operating system to Web serving and email. Key technology products developed with open-source software have overtaken and surpassed the commercial efforts of billion dollar companies like Microsoft and IBM to dominate software markets. Learn the inside story of what led Netscape to decide to release its source code using the open-source mode. Learn how Cygnus Solutions builds the world's best compilers by sharing the source code. Learn why venture capitalists are eagerly watching Red Hat Software, a company that gives its key product -- Linux -- away.For the first time in print, this book presents the story of the open- source phenomenon told by the people who created this movement.Open Sources will bring you into the world of free software and show you the revolution.

The corporate market is now embracing free, "open source" software like never before, as evidenced by the recent success of the technologies underlying LAMP (Linux, Apache, MySQL, and PHP). Each is the result of a publicly collaborative process among numerous developers who volunteer their time and energy to create better software. The truth is, however, that the overwhelming majority of free software projects fail. To help you beat the odds, O'Reilly has put together Producing Open Source Software, a guide that recommends tried and true steps to help free software developers work together toward a common goal. Not just for developers who are considering starting their own free software project, this book will also help those who want to participate in the process at any level. The book tackles this very complex topic by distilling it down into easily understandable parts. Starting with the basics of project management, it details specific tools used in free software projects, including version control, IRC, bug tracking, and Wikis. Author Karl Fogel, known for his work on CVS and Subversion, offers practical advice on how to set up and use a range of tools in combination with open mailing lists and archives. He also provides several chapters on the essentials of recruiting and motivating developers, as well as how to gain much-needed publicity for your project. While managing a team of enthusiastic developers -- most of whom you've never even met -- can be challenging, it can also be fun. Producing Open Source Software takes this into account, too, as it speaks of the sheer pleasure to be had from working with a motivated team of free software developers.

This book enables you to leverage the state-of-the-art of creating open source based business models and of managing open source in the development cycle of commercial software and during due diligence in mergers and acquisitions. In addition, it provides information about why investments in open source makes sense. Practitioners, investors and consultants created this book to help professionals in the software business like investors, executives, business developers, product managers, architects, developers, quality managers, development operations managers as well as students to get acquainted and proficient in using open source products in a commercial context. First, the focus is on business model impact of open source products and open source licenses. Dr. Karl Michael Popp gives an overview of the different types of business models for open source companies. Dr. Josef Waltl shows how open source licenses and intellectual property strategies can create a unique business model based on a combination of open source and proprietary software. Then, the focus is on detection and license compliance aspects of open source software in mergers and acquisitions. The acquisition of a software vendor requires the review of intellectual property rights including open source license compliance as described by Dr. Karl Michael Popp. The following new chapter, authored by Joseph Jacks from OSS Capital, provides fundamentals of the open source business by elaborating on value creation and value capture for commercial open source companies. Then, two chapters cover the offerings of tool vendors for governance of open source software but also for development enablement. First, Bill Weinberg and Greg Olsen show the broad offering of solutions of Black Duck Software, a provider for open source governance and enablement tools. The next, new chapter, provided by Snyk, focuses on development aspects of using open source software as part of commercial products like assistance for developers in selection and in continuously updating open source components during the software development lifecycle.

Since its emergence in the mid-1980s through the protagonism of free software and open source movements, the concept of freely shareable technology has steadily established itself in the following decades to enter the 21st century as a leading industrial paradigm. From the original ambit of software technology, the principles of collaborative construction of publicly accessible knowledge grounding the open source paradigm have been extended to embrace any intellectual artifact made available under non-exclusive rights of utilization, development, and distribution. It is noteworthy, however, that whilst on one hand it is not difficult to enumerate advantages of the use of open source products by individuals and organizations—whether related to cost reduction, socio-technological inclusion, governance of technology development, security and privacy transparency, among others—on the other hand, it is not as immediate to identify their motivation to develop open source technology. While there may surely be initiatives driven by either ethical grounds, personal avocation, or public policies, those reasons alone do not explain the lasting success of many large community-driven projects, nor why large commercial enterprises massively invest in open source development. Business Models and Strategies for Open Source Projects investigates the rationales and the strategy underlying companies’ decisions to produce and release open source products as well as which business models have succeeded. Covering topics such as embedded systems, open source ecosystems, and software companies, this premier reference source is a valuable resource for entrepreneurs, business leaders and managers, students and educators of higher education, librarians, software developers, researchers, and academicians.

The chapters describe key findings of the respective works, show their relevance and applicability to practice and industrial software engineering projects, and provide additional information and findings that have only been discovered afterwards, e.g. when applying the results in industry. This way, the book is not only interesting to other researchers, but also to industrial software professionals who would like to learn about the application of state-of-the-art methods in their daily work.

The quick growth of computer technology and development of software caused it to be in a constant state of change and advancement. This advancement in software development meant that there would be many types of software developed in order to excel in usability and efficiency. Among these different types of software was open source software, one that grants permission for users to use, study, change, and distribute it freely. Due to its availability, open source software has quickly become a valuable asset to the world of computer technology and across various disciplines including education, business, and library science. The Research Anthology on Usage and Development of Open Source Software presents comprehensive research on the design and development of open source software as well as the ways in which it is used. The text discusses in depth the way in which this computer software has been made into a collaborative effort for the advancement of software technology. Discussing topics such as ISO standards, big data, fault prediction, open collaboration, and software development, this anthology is essential for computer engineers, software developers, IT specialists and consultants, instructors, librarians, managers, executives, professionals, academicians, researchers, and students.

This research aims at synthesizing literature on social capital theory and OSS communities to arrive at a conceptual model of social capital and individuals' value creation in OSS communities. Accordingly, it targets at replicating prior research that used social capital to predict diverse forms of outcome by using alternative operationalizations of the different social capital dimensions as well as forms of outcome and includes firm-sponsorship as moderator into the models. As a result of this research, it can be noted that the proven relationship between an OSS contributor's social capital and his created value is affected by firm-sponsorship. Furthermore, it could be shown that the proven relationship between an OSS contributor's social capital and associated individual outcomes is not affected by firm-sponsorship.
