    The state of Reactive Streams

    Peter Paul van de Beek, Peter Brouwers, on 14-11-2019
    Category: Podcast

    The state of Reactive Streams – watch the presentation and listen to the podcast. International Keynote speaker Oleh Dokuka gave a presentation on the state of Reactive Streams at bol.com. We took advantage of this opportunity and interviewed him for the podcast. The Reactive Streams specification is state of the art for asynchronous, non-blocking data streams with the fine-grained flow control. Clearly, that was done for a good future… but, does it have any future nowadays? How other programming ecosystems reacted to the appearance of the reactive-streams standard and did they adopted that…

How does this relate to Tech? Or, to be more precise, how does that relate to the design of the webshop? And how do we know if we succeed or fail, is it a gut feeling or do we learn through structured research? In this episode, we explore the theme of success, failure and learning together with…

    Category: Testing, Events

    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?
