Firm Sponsored Developers In Open Source Software Projects

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.

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.

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.

Participation of firms in Open Source Software (OSS) development is steadily increasing. In fact, a substantial part of OSS projects today are developed in informal collaboration between firms and a community of voluntary contributors. As more and more firms are active in OSS, acquisitions of firms active in OSS development occur increasingly often. Yet, despite the economic and practical importance of OSS, research has so far overlooked this phenomenon. This dissertation explores this phenomenon of acquisitions of firms active in OSS development. Michael Vetter examines the role of OSS in the pre-acquisition phase and the impact of acquisitions on OSS development in the post-acquisition phase. Using qualitative and quantitative research methods, the author examines acquisition motives, acquisition likelihood, timing of acquisitions, and outcomes of acquisitions and discuss mechanisms behind variations across acquisitions.The findings from the studies contribute to research on acquisitions and OSS development while also providing insights into how to leverage OSS in target search, selection and evaluation processes as well as how to effectively manage acquisitions of firms active in OSS and the communities around them.

Open Source Software Development offers the first serious (and academically rigorous) study of the OSS phenomenon. The authors examine several key aspects of OSS, for example: Definitions of OSS and Free Software, including a comprehensive guide to both OSS and non-OSS software licences. Profiles of key OSS products, projects, companies and organisations. Analysis of the technological motivations for OSS development, with explicit reference to the possibility of OSS addressing the "software crisis."

This book provides something far more valuable than either the cheerleading or the fear-mongering one hears about open source. The authors are Dan Woods, former CTO of TheStreet.com and a consultant and author of several books about IT, and Gautam Guliani, Director of Software Architecture at Kaplan Test Prep & Admissions. Each has used open source software for some 15 years at IT departments large and small. They have collected the wisdom of a host of experts from IT departments, open source communities, and software companies. Open Source for the Enterprise provides a top to bottom view not only of the technology, but of the skills required to manage it and the organizational issues that must be addressed.

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.
