Most venture capital funding in open source flows to single-vendor open source firms. With the struggles over licensing in the cloud, these companies find themselves at the crossroads: Stay true to open source or move to proprietary licenses, abandoning the goodwill and opportunities that come with open source. In this talk I will review how this business model works, discuss the challenges posed to vendors by large cloud providers, and review the current options on the table.]]>

Over the last few years, we have shifted most of our courses from traditional upfront lecturing to project-based learning. Each course consists of multiple projects with three main stakeholders: students, teachers, and industry. Using AMOS, our "agile methods and open source" software engineering course as the example, we review our course concept and discuss our experiences. We take the perspectives of the three stakeholders in turn: Achieving learning goals and performing meaningful work (students), fulfilling both an educational and an economic mission (university), and receiving a return on time and monetary investment (industry). The perhaps surprising result is that these three perspectives can work together well and make reaching the each stakeholder's goal easier.]]>

Open source creates a new career ladder for software developers, orthogonal to the traditional career in software firms. Advancing on this career ladder can win developers broader recognition for their work, increase their salaries, and improve their job security. Software developers, project and hiring managers, and personnel departments alike need to understand this new dimension in a developer’s career. This talk explains the career and discusses what skills a developer should possess or train to be successful.]]>

The development processes of open source software are different from traditional closed source development processes. Still, open source software is frequently of high quality. Thus, we are investigating how open source software creates high quality and whether it can maintain this quality for ever larger project sizes. In this paper, we look at one particular quality indicator, the density of comments in open source software code. In a large-scale study of more than 5,000 projects, we find that active open source projects document their source code, and we find that the comment density is independent of team and project size, but not of project age. In future work, we intend to correlate comment density with project success or failure.]]>

Twitter is taking the world by storm. Is this consumer service also relevant for the enterprise software world? In December 2008, we undertook several focus groups with the goal of understanding enterprise micro-blogging as a possible stand-alone product or at least a major feature of business applications. We analyzed the focus groups’ transcriptions from a technology adoption perspective: Would people buy? What core issues might drive or hinder adoption? The results are in line with expectations for this fast-growing medium of communication and collaboration. We can now put more emphasis on determining what features and drivers are more important than others. This talk presents our results and proposes the next steps of market research for SAP.]]>
