Remember the game that was created with the Elm language during Zalando’s Hack Week #4? We’ve been working on it via open source and it’s had a lot of improvements since then. Our goal remains the same — to put the game on the 404 page of the Zalando website, and at its current state, we’re as close as ever to reaching it. In this post we will go through the game’s progress in detail.

Before I became a developer, I graduated college as a math and science teacher. Teaching is something I fundamentally believe in and think anyone can do, no matter their skill level. When I first arrived at Zalando, I joined a team that had recently decided to use React. However, few had concrete knowledge about the framework. My team decided to join three other interested teams and attend a React workshop every two weeks.

The Zalando Web Guild is a group of like-minded frontend engineers who meet bi-weekly to discuss new technologies, share knowledge, and collaborate on diverse projects. With so many independent teams and engineers from different backgrounds, we felt that there was too little communication between them, so that teams often solved similar problems instead of sharing code and knowledge.

The Zalando Testing Team creates tools that improve code quality for development teams. One way to improve code quality is to write tests – and we do write a lot of tests! But are these tests good at catching bugs? If code is refactored and the test suite is still green, can we be confident that we didn’t break anything? This post introduces a new tool that verifies whether or not tests are actually able to find errors in the code.

There are common questions which come up repeatedly in Java. Even if you know the answer, it's worth getting a more thorough understanding of what is happening in these cases. How do I compare Strings? The more general question is, how do I compare the contents of an Object? What is surprising when you use Java for the first time is that if you have a variable like String which is a reference to an Object, not the Object itself.
