Do as i Do, Not as i Say: Do Contribution Guidelines Match the GitHub Contribution Process?

Developer contribution guidelines are used in social coding sites like GitHub to explain and shape the process a project expects contributors to follow. They set standards for all participants and 'save time and hassle caused by improperly created pull requests or issues that have to be rejected and re-submitted' (GitHub). Yet, we lack a...

Self-healing properties of recycled asphalt mixtures containing metal waste: An approach through microwave radiation heating

The concept of self-healing asphalt mixtures by bitumen temperature increase has been used by researchers to create an asphalt mixture with crack-healing properties by microwave or induction heating. Metals, normally steel wool fibers (SWF), are added to asphalt mixtures prepared with virgin materials to absorb and conduct thermal energy....

How Modern News Aggregators Help Development Communities Shape and Share Knowledge

Many developers rely on modern news aggregator sites such as reddit and hn to stay up to date with the latest technological developments and trends. In order to understand what motivates developers to contribute, what kind of content is shared, and how knowledge is shaped by the community, we interviewed and surveyed developers that participate...

Effect of RAP and fibers addition on asphalt mixtures with self-healing properties gained by microwave radiation heating

Microwave heating of asphalt mixtures containing metal fibers is a promising technology for asphalt pavement rehabilitation. The main characteristic of these types of mixtures is that they have the ability to self-heal their cracks when external microwave heating is applied. Prior to this study, the assessment of crack-healing has only been...

When Testing Meets Code Review: Why and How Developers Review Tests

Automated testing is considered an essential process for ensuring software quality. However, writing and maintaining high-quality test code is challenging and frequently considered of secondary importance. For production code, many open source and industrial software projects employ code review, a well-established software quality practice, but...

Work Practices and Challenges in Pull-Based Development: The Contributor’s Perspective

The pull-based development model is an emerging way of contributing to distributed software projects that is gaining enormous popularity within the open source software (OSS) world. Previous work has examined this model by focusing on projects and their owners-we complement it by examining the work practices of project contributors and the...

Work practices and challenges in pull-based development: The integrator's perspective

In the pull-based development model, the integrator has the crucial role of managing and integrating contributions. This work focuses on the role of the integrator and investigates working habits and challenges alike. We set up an exploratory qualitative study involving a large-scale survey involving 749 integrators, to which we add quantitative...

Automated detection of test fixture strategies and smells

Paper accepted for publication in the Proceedings of the Sixth International Conference on Software Testing, Verification and Validation, IEEE Computer Society, 18-22 March 2013, ISBN 978-1-4673-5961-0, doi: 10.1109/ICST.2013.45 Designing automated tests is a challenging task. One important concern is how to design test fixtures, i.e. code that...

Understanding Ajax Applications by Connecting Client and Server-Side Execution Traces

Author's version of the work published in: Empirical Software Engineering (Springer), 18 (2), 2013; doi:10.1007/s10664-012-9200-5 Ajax-enabled web applications are a new breed of highly interactive, highly dynamic web applications. Although Ajax allows developers to create rich web applications, Ajax applications can be difficult to comprehend...

Understanding Ajax applications by connecting client and server-side execution traces

Ajax-enabled Web applications are a new breed of highly interactive, highly dynamic Web applications. Although Ajax allows developers to create rich Web applications, Ajax applications can be difficult to comprehend and thus to maintain. For this reason, we have created FireDetective, a tool that uses dynamic analysis at both the client (browser...

Test Confessions: A Study of Testing Practices for Plug-in Systems

Testing plug-in-based systems is challenging due to complex interactions among many different plug-ins, and variations in version and configuration. The objective of this paper is to increase our understanding of what testers and developers think and do when it comes to testing plug-inbased systems. To that end, we conduct a qualitative ...

Connecting traces: Understanding client-server interactions in Ajax applications

Ajax-enabled web applications are a new breed of highly interactive, highly dynamic web applications. Although Ajax allows developers to create rich web applications, Ajax applications can be difficult to comprehend and thus to maintain. For this reason, we have created FireDetective, a tool that uses dynamic analysis at both the client (browser...
