AbstractThe role of non-coding contributors in Open Source Software (OSS) is poorly understood. Most of current research around OSS development focuses on the coding aspects of the project (e.g., commits, pull requests or code reviews) while ignoring the potential of other types of contributions. Often, due to the assumption that these other contributions are not significant in number and that, in any case, they are handled by the same people that are also part of the “coding team”. This paper aims to investigate whether this is actually the case by analyzing the frequency and diversity of non-coding contributions in OSS development. As a sample of projects for our study we have taken the 100 most popular projects in the ecosystem of NPM, a package manager for JavaScript. Our results validate the importance of dedicated non-coding contributors in OSS and the diversity of OSS communities as, typically, a contributor specializes in a specific subset of roles. We foresee that projects adopting explicit policies to attract and onboard them could see a positive impact in their long-term sustainability providing they also put in place the right governance strategies to facilitate the migration and collaboration among the different roles. As part of this work, we also provide a replicability package to facilitate further quantitative role-based analysis by other researchers.

Abstract. Indoor mapping is an essential process in several applications such as the visualization of space and its utilization, security and resource planning, emergency planning and location-based alerts and, last but not least, indoor navigation. In this work, a completely free and open-source (FOS) approach to map indoor environments, and to navigate through them, is presented. Our tests were carried out within Sapienza University of Rome public buildings; in detail, Letters and Philosophy faculty and Engineering faculty indoor environments were mapped. To reach this goal, only open source software such as Quantum GIS (QGIS) and open-source platforms like Open Street Map (OSM) and its indoor viewer, Open Level Up (OLU) were adopted. A database of indoor environments of the two faculties, completely compatible with OLU, was created through QGIS. In this way, a public territorial information system of classrooms, offices and laboratories is accessible to everyone who can, hence, add or modify the information, following the principle of crowdsourcing and of Volunteered Geographic Information (VGI). The developed procedure is now standard and its outputs accepted by the OSM community. Hence, the long-term developments of this project are the proposal for the volunteered and cooperative indoor mapping and design of strategic buildings and infrastructures (hospitals, schools, public offices, shopping centers, stations, airports etc.), starting from the available information (indoor layouts) and knowledge acquired through experience of people who normally work inside them and/or visit them frequently. In this context it is possible to state that the development of VGI for internal maps for strategic buildings, infrastructures and denied GNSS environments, not only supports and improves internal and external navigation without interruption, but can also have a significant positive impact on security and emergency management.

Liquid Handling Robot

We introduce a robot developed to perform feedback-based experiments, such as droplet experiments, a common type of experiments in artificial chemical life research. These experiments are particularly well suited for automation because they often stretch over long periods of time, possibly hours, and often require that the human takes action in response to observed events such as changes in droplet size, count, shape, or clustering or declustering of multiple droplets. Our robot is designed to monitor long-term experiments and, based on the feedback from the experiment, interact with it. The combination of precise automation, accurately collected experiment data, and integrated analysis and modeling software makes real-time interaction with the experiment feasible, as opposed to traditional offline processing of experiments. Last but not least, we believe the low cost of our platform can promote artificial life research. Furthermore, prevalently, findings from an experiment will inspire redesign for novel experiments. In addition, the robot’s open-source software enables easy modification of experiments. We will cover two case studies for application of our robot in feedback-based experiments and demonstrate how our robot can not only automate these experiments, collect data, and interact with the experiments intelligently but also enable chemists to perform formerly infeasible experiments.

Abstract. Many open source software communities rely on volunteer contributors and it is important to motivate, engage and retain members of the community to ensure long term sustainability of the community and software. Barrier to entry can be a problem for new developers and can stop them from contributing to large projects. It is important to mentor and guide new volunteers in an open source project and organisation such as OSGeo. The question is then raised how can open source organizations bridge this gap and bring younger developers into the organizations and ensure that they remain, in order to contribute something meaningful? OSGeo participated for a third time in Google Code-in (GCI). Google Code-in is an online competition that introduces teenagers (13–17 years) to open source development over the course of seven weeks. In the 2019 Google Code-in, there were 29 participating open source organisations, over 3000 students from more than 75 countries that completed 13 000+ tasks. During GCI, OSGeo had the lowest number of mentors in its three years of the competition but its highest number of completed tasks. Many of the submissions from the students was of a high standard and some of the task submissions got accepted into the projects. Having new developers in any open source community is key to the survival of the community and retaining them is also key to the longevity of any of the projects and it gives them time to contribute something meaningful.

Because a Free and Open Source Software (F/OSS) project is unlikely to sustain a long-term success unless there is an associated community that provides the platform for developers, users, and user-turned-developers to collaborate with each other, understanding the well-observed phenomenon that F/OSS systems experience “natural product evolution” cannot be complete without understanding the structure and evolution of their associated communities. This chapter examines the structure of F/OSS communities and the co-evolution of F/OSS systems and communities based on a case study. Although F/OSS systems and communities generally co-evolve, they co-evolve differently depending on the goal of the system and the structure of the community. A systematic analysis of the differences leads us to propose a classification of F/OSS projects into three types: Exploration-Oriented, Utility-Oriented, and Services-Oriented. Practical implications of realizing the co-evolution and recognizing the different types of F/OSS projects are discussed to provide guidance for F/OSS practitioners.
