Open-source software development projects are almost always collaborative and distributed. Despite the difficulties imposed by distance, these projects have managed to produce large, complex, and successful systems. However, there is still little known about how open-source teams manage their collaboration. In this paper we look at one aspect of this issue:(More)
Many tasks in software engineering can be characterized as source to source transformations. Design recovery, software restructuring, forward engineering, language translation, platform migration and code reuse can all be understood as transformations from one source text to another. TXL, the Tree Transformation Language, is a programming language and rapid(More)
Community-based question answering services accumulate large volumes of knowledge through the voluntary services of people across the globe. Stack Overflow is an example of such a service that targets developers and software engineers. In general, questions in Stack Overflow are answered in a very short time. However, we found that the number of unanswered(More)

Although shared software repositories are commonly used during software development, it is typical that a software developer browses and edits a local snapshot of the software under development. Developers periodically check their changes into the software repository; however, their interaction with the local copy is not recorded. Local interaction(More)
Clone detector results can be better understood with tools that support visualization and facilitate in-depth analysis. In this tool demo paper we present VisCad, a comprehensive code clone analysis and visualization tool that provides such support for the near-miss hybrid clone detection tool, NiCad. Through carefully selectedmetrics and visualization(More)
The year 2000 problem posed a difficult problem for many IT shops world wide. The most difficult part of the problem was not the actual changes to ensure compliance, but finding and classifying the data fields that represent dates. This is a problem well suited to design recovery. This paper presents an overview of LS/2000, a system that used design(More)
Extracting code clone genealogies across multiple versions of a program and classifying them according to their change patterns underlies the study of code clone evolution. While there are a few studies in the area, the approaches do not handle near-miss clones well and the associated tools are often computationally expensive. To address these limitations,(More)
