The Spaces Championship – our code competition

It was briefly mentioned in our episode on Advent of Code. We also started an internal Coding Championship. Spaces Championship. Let’s dive into this and find out what it is all about. From our personal experience, we know that is easier to train and improve when we are in a competition. Could it be that the same mechanism is here at work too? Let us know when you think we should open-up this competition externally as well, goto Linkedin, mailto: techlab@bol.com or twitter us: @bol_com_Techlab Guests Harmen Prins – Software…

In this episode we talk about GO. Go is not a language that is used the most at bol.com. That’s is Java, together with Kotlin. In 2014 it was introduced for the first time and reached a steady but not so big user group. Recently, along with the move to the cloud, we experience a second wave of adoption. When you listen to the stories our two enthusiastic guests share in this episode, you might even believe Go is the future. Guests Rogier Lommers Tom Stoepker Hosts Peter Brouwers Peter…

An accurate forecast makes it much easier to buy the correct amount of products from suppliers, know what you need to keep on stock and even know what the sales will do with specific promotions. Over the last couple of years, this domain changed dramatically because of the introduction of Data Science and Artificial Intelligence. In this episode, we chat about this changing playing field to share our experiences with you. Guests Harmen Prins Erick Webbe Hosts Peter Brouwers…

Our Kotlin adoption journey

Category: Podcast Tags: Development Kotlin software engineering Podcast Technology

Kotlin was first used by our teams a couple of years ago. It had an interesting start that shows how we adopt technology in general. In different feature teams a group of software engineers explored their own use cases for Kotlin. Some very enthusiastic, some a bit more skeptical and eventually they found each other. A new community in bol.com was born, the Kotlin community. In this episode we talk about this journey, the use cases, the adaption and the impact on frameworks that we use in our feature teams.

At bol.com we use GraphQL in our IT landscape, and we’ve found a convenient way of working with these API’s we would like to share. By generating our GraphQL queries from Java objects by using annotations, developers don’t need to worry about the query, and don’t need to maintain both a query and a domain object anymore.
