A study and toolkit for asynchronous programming in c#

Asynchronous programming is in demand today, because responsiveness is increasingly important on all modern devices. Yet, we know little about how developers use asynchronous programming in practice. Without such knowledge, developers, researchers, language and library designers, and tool providers can make wrong assumptions. We present the...

Quantifying the encapsulation of implemented software architectures

Evaluating feature change impact on multi-product line configurations using partial information

Evolving large-scale, complex and highly variable systems is known to be a difficult task, where a single change can ripple through various parts of the system with potentially undesirable effects. In the case of product lines, and moreover multi-product lines, a change may affect only certain variants or certain combinations of features, making...

Testing principles, current practices, and effects of change localization

Detecting and Visualizing Inter-Worksheet Smells in Spreadsheets

Detecting Code Smells in Spreadsheet Formulas

Spreadsheets are used extensively in business processes around the world and just like software, spreadsheets are changed throughout their lifetime causing maintainability issues. This paper adapts known code smells to spreadsheet formulas. To that end we present a list of metrics by which we can detect smelly formulas and a visualization...

Measuring Library Stability Through Historical Version Analysis

Backward compatibility is a major concern for any library developer. In this paper, we evaluate how stable a set of frequently used third-party libraries is in terms of method removals, implementation change, the ratio of change in old methods to change in new ones and the percentage of new methods in each snapshot. We provide a motivating...

Control of hybrid ship drive systems

Stricter regulations on emissions force ship owners and designers to come up with new solutions for ship propulsion systems. Hybrid drive systems consisting of prime movers and batteries, like in the Toyota Prius, show great potential, especially in special ships like harbour tugs. Economic and environmental performance of such systems strongly...

The Impact of Social Media on Software Engineering Practices and Tools

Adinda: A knowledgeable, Browser-Based IDE

In practice, many people have to work together to develop and maintain a software system. However, the programmer’s key tool, the Integrated Development Environment (IDE), is a solo-tool, serving to help individual programmers understand and modify the system. Such an IDE does not leverage the knowledge other team members may have of the design...

Model-Driven Software Evolution: A Research Agenda

Software systems need to evolve, and systems built using model-driven approaches are no exception. What complicates model-driven engineering is that it requires multiple dimensions of evolution. In regular evolution, the model- ing language is used to make the changes. In meta-model evolution, changes are required to the modeling notation. In...
