What’s wrong with German university startup incubators?
Let’s use the simple root cause analysis method of asking multiple times why. 1. Too many German university incubators are a joke. Why are they a joke? 2. Because they don’t deliver what they should be delivering: Return on investment for the commercialization of all the intellectual property created from public funding given to them.…

A systematic review of common beginner programming mistakes in data engineering [CSEE&T 2025]
Abstract The design of effective programming languages, libraries, frameworks, tools, and platforms for data engineering strongly depends on their ease and correctness of use. Anyone who ignores that it is humans who use these tools risks building tools that are useless, or worse, harmful. To ensure our data engineering tools are based on solid foundations,…

An empirical study of Jayvee, a domain-specific language for data engineering, on understanding data pipeline architectures [SP&E Journal]
Abstract A large part of data science projects is spent on data engineering. Especially in open data contexts, data quality issues are prevalent and are often tackled by non-professional programmers. We introduce and evaluate Jayvee, a domain-specific language for data engineering aimed at reducing barriers to building data pipelines. We show that a structured DSL…

Why and how do organizations create user-led open source consortia? [INFSOF Journal]
Abstract Context User-led open source (OS) consortia (foundations) consist of organizations from industries beyond the software industry collaborating to create open-source software solutions for their internal processes. Initially pioneered by higher education organizations in the 2000s, this concept has gained traction in recent years across various industries. Objective This study has two research objectives (ROs).…

“Two hard things in computer science” explained
You may have heard the saying “There are only two hard things in computer science: Cache invalidation and naming things.” The web and Martin Fowler attribute this saying to one Phil Karlton; I actually thought it was Leslie Lamport, but maybe I’m confusing it with this saying “A distributed system is one in which the…
