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…

TL;DR: this article discusses in detail my presentation at Spaces Summit 2018. I talked about the need to stop smashing our keyboards and “blindly” focus on “high-speed”, and start thinking about what we are doing, why and how we are doing it.

bol.com has two speeds of operation: “very fast” and “extremely fast”. In this whirlwind it can sometimes be difficult for teams to share knowledge or just talk about things they find interesting. A handful of colleagues decided something needed to be done about this. What better way, they thought, than to just organize an entire conference by themselves?

For years now, the role of the tester has been the topic of discussion and debate. The way we develop software in the age of Scrum, Agile and DevOps appears to have shifted the tasks and responsibilities associated with software testing for some us. Competitive markets demand a shorter time to market, without impacting quality. During this meetup we will take a deep dive into this topic, started off by James Bach, who will present his vision, followed by the visions of Xebia and bol.com. We hope to offer some…

What is testing? What is the testing role? Is testing a demonstration that a product fulfills its declared functional requirements? If machinery can be programmed to check hundreds and thousands of functions in a second, do we need testers any more? Michael Bolton – The balance between social & technical skills Michael Bolton says we do, but not so much to check for functional correctness—which arguably should never have been a central part of the tester’s job in the first place. We need people in a testing role to do…
