    Spaces Talk #6: Making Demos Great Again

    On: 27 Oct 2021 at:

    At this year’s Spaces Summit, I presented a talk on Streamlit: a new web application framework in Python, which is perfect for making data science demos. About the talk As Data Scientists, we often need to quickly prototype ideas and showcase those projects to the business. Yet, Python scripts are not very visually appealing and Powerpoint is not always suitable. You also don’t want to spend weeks setting up that throw-away, unmaintainable Flask application, just for the purpose of showcasing your idea. Fortunately, there’s a solution to all of these…

    On: 27 Oct 2021 at: has two speeds of operation: “very fast” and “extremely fast”.

    The future of the testing role

    On: 15 Mar 2017 at: HQ, Utrecht

    For years now, the role of the tester has been the topic of discussion and debate.
