Collecting data from distributed FOSS projects

A key trait of Free and Open Source Software (FOSS) development is its distributed nature. Nevertheless, two project-level operations, the fork and the merge of program code, are among the least well understood events in the lifespan of a FOSS project. Some projects have explicitly adopted these operations as the primary means of concurrent development. In this study, we examine the effect of highly distributed software development, is found in the Linux kernel project, on collection and modelling of software development data. We find that distributed development calls for sophisticated temporal modelling techniques where several versions of the source code tree can exist at once. Attention must be turned towards the methods of quality assurance and peer review that projects employ to manage these parallel source trees. Our analysis indicates that two new metrics, fork rate and merge rate, could be useful for determining the role of distributed version control systems in FOSS projects. The study presents a preliminary data set consisting of version control and mailing list data.

Lukas Foss's The Prairie (1942): Building Community through Music

Lukas Foss's The Prairie, a seven-movement cantata for SATB soloists, mixed chorus, and orchestra, is a well-crafted and audience-friendly setting of the poem of the same name by Carl Sandburg. Acclaimed at its 1944 premiere, The Prairie has not enjoyed a robust performance history due in large part to numerous inconsistencies between the score and parts which render the work challenging to perform. Heretofore, each conductor has individually located these inconsistencies and made the necessary adjustments for performances. In this document, resources have been assembled which identify and correct many of the inconsistencies, thus facilitating more performances in the future. The Prairie is an ideal vehicle for a project-based chorus, which is itself an opportunity to create a new community. A correlation may exist between "community" and "vulnerability;" that is, when a choral singer feels comfortably connected to fellow singers, he or she may be more likely to open up to new ways of making sounds for the ultimate service of the music. Results are inconclusive, but the project points to a successful strategy for creating an affirming new community and to positive musical and nonmusical results of intentional community-building.

A Qualitative Study on the Adoption of Copyright Assignment Agreements (CAA) and Copyright License Agreements (CLA) within Selected FOSS Projects

Open source software projects are multi-collaborative works incorporating the contributions of numerous developers who, in spite of publishing their code under a public license such as GPL, Apache or BSD, retain the copyright in their contributions. Having multiple copyright-owners can make the steering of a project difficult, if not impossible, as there is no ultimate authority able to take decisions relating to the maintenance and use of the project. This predicament can be remedied by centring the dispersed copyrights in a single authority via contributor agreements. Whether to introduce contributor agreements, and if so in which form, is a pressing question for many emerging, but also for established projects. The current paper provides an insight into the ethos of different projects and their reason for adopting or rejecting particular contributor agreements. It further examines the exact set-up of the contributor agreements used and concludes that smart drafting can blur the difference between CAAs and CLAs to a considerable extent, manoeuvring them into a legal grey area. To avoid costly litigation to test the legal enforceability of individual clauses, this paper proposes the establishment of an international committee comprised of developers, product managers and lawyers interested in finding a common terminology that may serve as a foundation for every contributor agreement
