Barros Cândido, J. (author), Aniche, Maurício (author), van Deursen, A. (author)Modern software development and operations rely on monitoring to understand how systems behave in production. The data provided by application logs and runtime environment are essential to detect and diagnose undesired behavior and improve system reliability. However, despite the rich ecosystem around industry- ready log solutions, monitoring...journal article 2021

Barros Cândido, J. (author), Haesen, Jan (author), Aniche, Maurício (author), van Deursen, A. (author)Logging is a development practice that plays an important role in the operations and monitoring of complex systems. Developers place log statements in the source code and use log data to understand how the system behaves in production. Unfortunately, anticipating where to log during development is challenging. Previous studies show the...conference paper 2021

Shruthi Kashyap, Shruthi (author), Rao, V.S. (author), Venkatesha Prasad, Ranga Rao (author), Staring, Toine (author)This chapter studies the existing research and solutions in using TCP/IP on low data-rate and high delay networks like NFC. It concludes that the problem on hand, i.e., using TCP/IP on time-slotted NFC in the cordless kitchen appliances, is unique and hence new novel methods are needed in this case.book chapter 2021

Soltani, M. (author), Derakhshanfar, P. (author), Devroey, Xavier (author), van Deursen, A. (author)Crash reproduction approaches help developers during debugging by generating a test case that reproduces a given crash. Several solutions have been proposed to automate this task. However, the proposed solutions have been evaluated on a limited number of projects, making comparison difficult. In this paper, we enhance this line of research by...journal article 2020

Huijgens, H.K.M. (author), Rastogi, A. (author), Mulders, E.A. (author), Gousios, G. (author), van Deursen, A. (author)In 2014, a Microsoft study investigated the sort of questions that data science applied to software engineering should answer. This resulted in 145 questions that developers considered relevant for data scientists to answer, thus providing a research agenda to the community. Fast forward to five years, no further studies investigated whether the...conference paper 2020
