    Comparing the Performance of Data Processing Implementations
    (Softwaretechnik-Trends Band 43, Heft 4, 2023) Beierlieb, Lukas; Iffländer, Lukas; Prantl, Thomas; Kounev, Samuel
    This paper compares the execution speed of R, Python, and Rust implementations in the context of data processing. A real-world data processing task in the form of an aggregation of benchmark measure ment results was implemented in each language, and the execution times were measured. Rust and Python showed significantly superior performance compared to the R implementation. Further, we compared the results of different Python interpreters (the most recent versions of CPython and PyPy), also resulting in measurable variations. Finally, a study of the effectiveness of multithreading was performed.

    Teaching Software Testing Using Automated Grading
    (Proceedings of the Fifth Workshop "Automatische Bewertung von Programmieraufgaben" (ABP 2021),virtual event, October 28-29, 2021, 2021) Beierlieb, Lukas; Iffländer, Lukas; Schneider, Tobias; Prantl, Thomas; Kounev, Samuel
    Software testing has become a standard for most software projects. However, there is a lack of testing in many curricula, and if present, courses lack instant feedback using automated systems. In this work, we show our realization of an exercise to teach software testing using an automated grading system. We illustrate our didactic goals, describe the task design and technical implementation. Evaluation shows that students experience only a slight increase in difficulty compared to other tasks and perceive the task description as sufficient.
