Testing your GitLab CI/CD pipeline

If you develop a pipeline as a service for other development teams you should treat it as a product and establish product development processes, a versioning strategy, etc. around it. Besides that, as potentially many teams will use and rely on your pipeline you want to make sure that new features don’t break existing functionality. This ensures that your customer base remains happy and able to deliver business value. Therefore you need some sort of testing and we will demonstrate a way to (integration-) test your GitLab CI/CD pipeline.

How to bootstrap a tech conference with a 100% women+ speaker lineup

A tech conference focused on data and AI in the midst of a hype around machine learning, and LLMs in particular. Fair enough.

We wanted to celebrate the excellence of women+ in the field. And to take it a step further, we wanted to provide our speakers and attendees with a safe and supportive environment - not only for learning, but also for networking and personal growth. Did we succeed?

No future-proof architectures!

Architecture: The term itself radiates stability. It seems clear, then, that good architecture should be future-proof. But precisely this goal often leads to problems. Does that mean it is better not to design future-proof architectures?

Willkommen im Himmel

Der Weg in die Cloud ist für Unternehmen mit einer existierenden IT-Infrastruktur nach wie vor mit viel Skepsis verbunden.

How we cut our website’s carbon emissions in half

Between 2010 and 2030, the environmental impact of the digital world is expected to triple. While network infrastructure and devices get more and more efficient, all of these improvements are eaten up by more and more people and devices being connected to the internet, but especially by websites which are becoming more and more bloated. On the desktop, the average page weight of a single web page is four times as much now as it was in 2010. On mobile devices, it’s even more dramatic: The average page weight is ten times as much as in 2010. In the summer of 2022, we decided that it’s about time that we take action and start decarbonising our company website.
