  • Is isEven() a bad function to have?

    Is isEven() a bad function to have?

    Someone on Twitter got all exasperated that there is an isEven() function in Javascript to compute whether a number is an even number. After all it is equivalent to the simple expression of ((n % 2) == 0); why would they not use this? Well, already this simple example contains most of what you need…

  • Challenges of working from home in software development during COVID-19 lockdowns [TOSEM Journal]

    Challenges of working from home in software development during COVID-19 lockdowns [TOSEM Journal]

    Abstract: The COVID-19 pandemic of 2020-2022 and the resulting lockdowns forced many companies to switch to working from home, swiftly, on a large scale, and without preparation. This situation created unique challenges for software development, where individual software professionals had to shift instantly from working together at a physical venue to working remotely from home.…

  • The Benefits of Pre-Requirements Specification Traceability [RE 2022]

    The Benefits of Pre-Requirements Specification Traceability [RE 2022]

    Abstract: Requirements traceability is the ability to trace requirements to other software engineering artifacts. Traceability can be classified as either pre- or post-requirements specifications (RS) traceability. Pre-RS traceability is the ability to trace between requirements and their origin. However, the benefits of pre-RS traceability are often not clear. In this article, we systematically lay out…

  • Will open source become the default way of developing software?

    Will open source become the default way of developing software?

    Someone on the internet said that open source will become the default way of developing software. This begs the question: What is open source software development? What about other forms of development? And why would open source be the default way? Open source software development There is no one way of developing open source software.…

  • A validation of QDAcity‑RE for domain modeling using qualitative data analysis [RE Journal]

    A validation of QDAcity‑RE for domain modeling using qualitative data analysis [RE Journal]

    Abstract: Using qualitative data analysis (QDA) to perform domain analysis and modeling has shown great promise. Yet, the evaluation of such approaches has been limited to single-case case studies. While these exploratory cases are valuable for an initial assessment, the evaluation of the efficacy of QDA to solve the suggested problems is restricted by the…

  • The JDownloader Immune System for Continuous Deployment [HICSS 2020]

    The JDownloader Immune System for Continuous Deployment [HICSS 2020]

    Abstract: Continuous deployment can reduce the time from a source code change to a newly deployed application significantly. Increased innovation speed can make all the difference in a competitive market situation. However, deploying at high frequency requires high speeds of discovering bugs in the deployed software. Using the JDownloader file download manager as our example,…
