With over 10 million git repositories, GitHub is becoming one of the most important source of software artifacts on the Internet. Researchers are starting to mine the information stored in GitHub's event logs, trying to understand how its users employ the site to collaborate on software. However, so far there have been no studies describing the quality(More)
Many software development projects struggle with creating and communicating a testing culture that is appropriate for the project's needs. This may degrade software quality by leaving defects undiscovered. Previous research suggests that social coding sites such as GitHub provide a collaborative environment with a high degree of social transparency.(More)
The microblogging service Twitter has over 500 million users posting over 500 million tweets daily. Research has established that software developers use Twitter in their work, but this has not yet been examined in detail. Twitter is an important medium in some software engineering circles—understanding its use could lead to improved support, and(More)
Software developers rely on media to communicate, learn, collaborate, and coordinate with others. Recently, social media has dramatically changed the landscape of software engineering, challenging some old assumptions about how developers learn and work with one another. We see the rise of the social programmer who actively participates in online(More)
The Social Web provides comprehensive and publicly available information about software developers, identifying them as contributors to open source projects, experts at maintaining ties on social network sites, or active participants on knowledge-sharing sites. These signals, when aggregated and summarized, could be used to define potential candidates'(More)
With over 10 million git repositories, GitHub is becoming one of the most important sources of software artifacts on the Internet. Researchers mine the information stored in GitHub’s event logs to understand how its users employ the site to collaborate on software, but so far there have been no studies describing the quality and properties of the available(More)
The multitude of social media channels that programmers can use to participate in software development has given rise to online developer profiles that aggregate activity across many services. Studying members of such developer profile aggregators, we found an ecosystem that revolves around the <i>social programmer</i>. Developers are assessing each other(More)
The adoption of software engineering practices cannot always be achieved by education or processes. However, social software has the potential for supporting deliberate behavior change. We present preliminary results of an experiment in which we encouraged computer science students to make more frequent commits to version control by using a social software(More)
Badly and inconsistently layouted business processes are hard to read for humans and therefore lack comprehensibility. Furthermore, processes generated by software have no layout at all. If stakeholders cannot comprehend the process descriptions, they are unable to validate them and ¿nd mistakes. By offering a fully automatic layout algorithm for BPMN, it(More)
Software developers use many different communication tools and channels in their work. The diversity of these tools has dramatically increased over the past decade and developers now have access to a wide range of socially enabled communication channels and social media to support their activities. The availability of such social tools is leading to a(More)
