Today's integrated development environments (IDEs) are hampered by their dependence on files and file-based editing. We propose a novel user interface that is based on collections of lightweight editable fragments, called bubbles, which when grouped together form concurrently visible working sets. In this paper we describe the design of a prototype IDE user(More)
We propose the metaphor of rubber sheet stretching for viewing large and complex layouts within small display areas. Imagine the original 2D layout on a rubber sheet. Users can select and enlarge diierent areas of the sheet by holding and stretching it with a set of special tools called handles. As the user stretches an area, a greater level of detail is(More)
At ICSE 2010, the Code Bubbles team from Brown University and the Code Canvas team from Microsoft Research presented similar ideas for new user experiences for an integrated development environment. Since then, the two teams formed a collaboration, along with the Microsoft Visual Studio team, to release Debugger Canvas, an industrial version of the Code(More)
Dynamic analysis is based on collecting data as the program runs. However, raw traces tend to be too voluminous and too unstructured to be used directly for visualization and understanding. We address this problem in two phases: the first phase selects subsets of the data and then compacts it, while the second phase encodes the data in an attempt to infer(More)
Dynamic software visualization is supposed to provide programmers with insights as to what the program is doing. Most current dynamic visualizations either use program traces to show information about prior runs, slow the program down substantially, show only minimal information, or force the programmer to indicate when to turn visualizations on or off. We(More)
Our goal is to use the vast repositories of available open source code to generate specific functions or classes that meet a user's specifications. The key words here are specifications and generate. We let users specify what they are looking for as precisely as possible using keywords, class or method signatures, test cases, contracts, and security(More)
