Speed vs. Skill

Every AI coding tool promises the same thing: unprecedented speed, effortless productivity, freedom from tedious work. The pitch is compelling. But what if feeling more productive and being more capable aren’t the same thing? Research shows that automation makes us feel more productive while eroding our skills. Let’s examine this tension through the lens of cognitive psychology.

Menschenlesbare Datenformate mit Jackson verarbeiten

Wir nutzen tagtäglich Datenformate. Zum Austausch von Informationen mit anderen Systemen oder auch zur Definition von Dingen wie unserem Build oder zur Konfiguration unseres Systems. Manche davon sind binär, aber auch viele bis heute direkt von Menschen lesbar. Für die Verarbeitung von JSON in Java hat Jackson eine hohe Verbreitung erreicht. Aber Jackson kann mehr als nur JSON, wie wir in diesem Artikel sehen werden.

Context Engineering: Managing AI-Generated Code Complexity

Keeping your scope small was always a good idea

Prompts als Programm in GPT-5

All Caps, Gebettel und Geschrei – Schnee von gestern. GPT-5 befolgt brutal jede Instruktion, selbst in versteckten Nebensätzen. Und verhungert, wenn wir nicht genau sagen, was wir wollen. Welche Konsequenzen hat das für Prompt Engineering und Agentenentwicklung?

Swiss Army Knife for Salesforce: LLM with In-Memory Database

Large Language Models (LLMs) struggle with transforming large datasets, particularly when performing aggregations that require calculations - essentially anything where you’d normally use GROUP BY or ORDER BY in SQL. But what if we need to retrieve extensive data from a system and process it with an LLM, but only have an API with limited functionality available? In this blog post, I present a solution I’ve implemented and tested.

Achieving Digital Sovereignty with Standard Software

In the context of IT system landscapes, digital sovereignty is often equated with autarky— complete independence from third parties. By that logic, , a company developing and operating all applications in-house would be the ultimate example of digital sovereignty. But does this idea really hold up?

Managing Geopolitical Risks with Enterprise Architecture

IT leaders in Europe increasingly face questions about whether geopolitical developments – such as data protection disputes or trade conflicts between the EU and the US – threaten the viability of US cloud services. The risks range from price increases and legal uncertainties to potential usage restrictions. CIOs must not only ensure functional IT operations but also proactively assess external risks. This article demonstrates how enterprise architecture methods can help identify risks early and develop viable alternatives.

A Governance Framework for Digital Sovereignty

In an increasingly connected world where digital infrastructure forms the backbone of our economy and society, the topic of digital sovereignty is gaining more and more attention. For decision-makers in German-speaking countries, this goes far beyond merely selecting a cloud provider. It’s about strategic agency, resilience, and the ability to actively shape one’s digital future. This article explores how a robust governance methodology can help organizations not only understand digital sovereignty but also put it into practice—without sacrificing convenience or innovation.

The Path to Heterogeneous Cloud Platforms

Digital transformation brings both challenges and opportunities for businesses. To create future-proof and flexible IT infrastructures, more and more companies are adopting multi-cloud or hybrid cloud strategies. This isn’t just about cost reduction, but also about aligning innovative services from different providers with regulatory requirements - particularly in the area of data protection. This article shows how targeted integration strategies can help you leverage the benefits of multi-cloud to optimize your existing infrastructure, reduce technical dependencies, and ensure long-term business success.

Digital Sovereignty: Why Architecture Matters and How to Make Your Company Resilient

In an era where digital systems form the backbone of our economy and society, control over one’s digital future is increasingly becoming the focus of strategic decisions. For many technology decision-makers in German-speaking regions, this is not just a political or regulatory challenge, but a fundamental task with far-reaching implications for software architecture work.

Think Locally: On-Premise LLMs as Drivers of Competitive Advantage

Consider this scenario: Your organisation has integrated AI tools into critical business processes, your legal team has carefully reviewed data processing agreements, and your IT department has configured systems to comply with GDPR requirements. Then, a foreign court issues an order that overrides all these protections, requiring your AI provider to indefinitely retain data that should be deleted—including potentially sensitive corporate information shared by your employees.

Digital Sovereignty as Self-Understanding

How implementation teams can escape the we-are-not-Google trap and collectively take responsibility for European solutions to European problems.

Software Analytics going crAIzy!

I’ve long been an advocate of treating software like data and analyzing it accordingly with tools like Python, pandas, Jupyter Notebook, Neo4j, and jQAssistant. In the era of AI and code transformation tools, seeing software as data gets more and more important when you want to improve your software system at a large scale. This blog post is a short interim report from me about my efforts taking software analysis to the next level.

Digitale Souveränität – Ein Definitionsversuch

Digitale Souveränität: Warum die Architektur zählt und wie Sie Ihr Unternehmen resilient machen

In einer Zeit, in der digitale Systeme das Rückgrat unserer Wirtschaft und Gesellschaft bilden, rückt die Kontrolle über die eigene digitale Zukunft zunehmend in den Fokus strategischer Entscheidungen. Für viele Technologieentscheider:innen im deutschsprachigen Raum ist dies nicht nur eine politische oder regulatorische Herausforderung, sondern eine grundlegende Aufgabe, die weitreichende Implikationen für die Software-Architekturarbeit hat.

The Sovereignty Trap: Between Tiananmen and Trump

We talk a big game about values and privacy, yet depend on AI that either denies historical atrocities or could cut us off tomorrow. Is this what Europe gets for dropping the ball on high tech infrastructure?

Updating OWASP’s Microservice Security Cheat Sheet: Practical Considerations & Recommendations

Turning principles and patterns into practice — just as promised.

From Data Graveyards to Knowledge Landscapes

Europe is sitting on a wealth of public data—but much of its potential remains untapped. The challenges are well known: fragmented portals, incompatible interfaces, and growing reliance on non-European platforms that slow innovation. While new industrial data spaces are emerging—enabling secure and sovereign exchange of sensitive information—public and industrial data ecosystems remain largely siloed. This article explores how Artificial Intelligence (AI) and the Model Context Protocol (MCP) can help bridge that gap and accelerate Europe’s shift from Open Data to Open Knowledge—supporting digital sovereignty and delivering greater value to society.

Pragmatische Architekturdokumentation für Entwicklungsteams

Eine gut gepflegte Architekturdokumentation ist nützlich, gerade auch für die Entwickler:innen eines Softwaresystems. Sie hilft nicht nur beim Verständnis, sondern sorgt auch dafür, dass sich wichtige Sachverhalte reflektiert diskutieren und klären lassen.
