I have been developing applications using #java since release 1.0. I have gone through all the different enterprise releases starting Servlets and EJB 1.0 to now with #Java EE/#Jakarta EE.

My goal in software development is to build programmes and features that people need and like to use. Only on the way did I slowly realise that simply writing code would probably not be enough. This journey continues to this day. In my blog post, I would like to share the crucial insights and changes of mind I had and give you an idea of what the world of software development is like.

Once a software development project has been completed, one of the major signs that it was successful is if the end product meets the customer’s expectations. For this to happen, what the customer wants has to be communicated to the project team, which then needs to implement everything on a technical level. This is where vision videos can help. I will explain exactly what these are in my blog post.

Fitting an agile development project into a waterfall-driven CSV framework and quality system can be a challenge. The first part of this series describes thorough preparation of some key topics before the start of the project to set a good foundation for this endeavor. Like the agile ceremonies and artifacts, the CSV tasks should be an integral part of the overall agile project planning. Likewise, the agile development approach is recommended to be described in the Validation Plan. This article shares best practices and observations and gives insights to some concrete activities that should be considered during the course of such a project.

Applications often contain resources that should only be available to certain users. Management users, for example, administer the information of their employees, whereas sales users administer the information of their customers. This requires closed areas, access to which is controlled by permissions. In this blog post, I would like to show you how to manage these access permissions in Keycloak and how to assign them to groups of users.

CSS is short for cascading style sheet. But how exactly does the cascade work? I'll explore this topic and lead you through the CSS inheritance process on the pages to follow. You will also learn all about the different types of style sheets and how the weighting of individual selectors is calculated in detail.

Computer System Validation (CSV) in GxP-regulated industries like pharmaceutical and medical device manufacturing is the testing and documenting to see if the software is fit for its intended use, is compliant to external regulations and internal procedures, thus providing a high degree of assurance that risks to patients, product quality and data integrity are minimized. This first part of the blog describes how to plan and what to do prior commencement of the project to fit in the agile validation approach with an existing CSV V-model process.

The goal of SOLID is to produce software that tolerates modifications, can be easily traced and that forms a basis for the components used in many software systems. In my blog post, I introduce you to the five SOLID principles in more detail.
