Let’s talk digital.

I’m an independent IT consultant and entrepreneur in the Internet and software business. I’m interested in design, enterprise applications, web apps and SaaS products. I design and develop business solutions and applications. I help companies in terms of software quality and knowledge transfer, e.g. with Angular and Spring Boot.

“Paging with Spring Boot” by Tom Hombergs: A Guide to Paging and Pagination in Spring-based Web Applications

In his article Paging with Spring Boot software engineer Tom Hombergs (a former fellow student) provides an in-depth explanation of paging and pagination concepts and how to implement those in web applications with Spring Data and its Pageable interface. The article covers aspects such as sorting, usage with Spring Data repositories and testing. It's a useful reference for iteratively retrieving and displaying a larger amount of items from a database in a Spring Boot and Spring Data context in an efficient manner. There's ...

What’s Digitalisation Actually About?

Digitalisation, or digital transformation, as it is sometimes also called is an important subject matter as well as challenge for businesses today. Therefore, I find it strangely confusing that sometimes aspects are lumped together under this umbrella that are not or only tangentially related to what digitalisation actually is about. So, here's my - perhaps opinionated - take on what digitalisation is actually about and what it entails. In a nutshell, digitalisation comprises these aspects: Rethinking and being willing to change existing processes. Making ...

A Guide to Refactoring Large Functions by Robert Muth

Software Engineer Robert Muth wrote this interesting article on refactoring large functions. The article starts with providing ample motivation for using functions (or methods in a strictly object-oriented context). Apart from making code shareable and reusable, which is only a minor benefit of functions / methods, reasons for writing code as functions are: giving a meaningful name to several lines of related code readability limiting visibility lowering indentation levels improving testability The article goes on to describe several common cues indicating that extracting the code at hand to ...

Kent Beck’s Novel Approach to Software Quality: test && commit || revert

In a Hanselminutes episode from December last year I heard preeminent programmer and agile advocate Kent Beck talk about his intriguing approach to creating working, high-quality code. In line with the steps this approach involves he calls it test && commit || revert. In lieu of the TDD circle of life (write test - test fails - write code - test passes - refactor - test fails ...) test && commit || revert has you commit each time when after a code ...

PivotHelper: Generate Pivot Tables and Pivot Charts from CSV and Microsoft Excel Spreadsheet Files

Somewhat recently, I regularly had to generate Pivot tables and corresponding charts from datasets provided as both CSV and Microsoft Excel files. Now, with its data source and pivot table tools Microsoft Excel usually lends itself to that sort of task. However, to completely automate this task VBA macros are required. Those too work quite nicely if one overcomes the initial aversion of working with Microsoft's not exactly well-designed and usable IDE for VBA macros (Excel's own macro recording feature is quite ...
