Most developers today use AI tools as faster autocomplete. Over the past few months, on a client project, I took a different path: multi-agent setups with Claude Code, where specialized agents work in parallel, review one another, and coordinate on their...

Anyone working with AI-assisted coding assistants today knows the promise: Type a description, and seconds later a working interface appears. Tools like Cursor, Claude Code, or GitHub Copilot deliver increasingly impressive results. Yet what is convincing...

Since June 2025, the Barrierefreiheitsstärkungsgesetz (BFSG), Germany's law implementing the European Accessibility Act, has been in effect. Most teams know they should be doing something about it, but in day-to-day work, the topic usually falls by the...

Introduction The Model Context Protocol (MCP) is an open standard that defines how AI models communicate with external tools, services, and data sources. It replaces ad-hoc integrations with a single, well-defined JSON-RPC 2.0 protocol, making it easy...

Modern LLMs demonstrate strong capability in inferring meaning from column names. A tool such as Genie can typically resolve pct_cust_attrit_q to "churn" or map rev_mrr_usd to a"MRR" through pattern recognition alone. On a small, well-structured table...

The Old Promise In the late 1970s, Stanford computer scientist Edward Feigenbaum coined the term "Knowledge Engineering". He described it as the process of extracting expert knowledge, structuring it, and making it usable within a software system. Central...

Garbage In, Garbage Out. This computing truism has never been more critical than in the age of AI. Large Language Models don't amplify poor data quality, they wrap it in confident-sounding prose that can mislead even experienced users. As organizations...

The Starting Point When we at codecentric recently took over a codebase from a previous service provider for a client, it quickly became clear that this would be no ordinary challenge. Backends, frontends, batch jobs, services — a grown application landscape...

In March 2026, we kicked off a modernization project for a client. Spring Boot was an obvious choice. There was a strategic decision behind it. There was existing know-how. There was existing infrastructure. The team was set. The work began. One of the...

TL;DR Uncontrolled agentic coding (“vibe coding”) delivers code quickly—and often leads to security and maintenance issues as soon as the software goes live. EXACT Coding (Example-guided AI-Collaborative Test-driven Coding) combines best practices: ....

Ralph Wiggum is the simple-minded boy from The Simpsons who says things like "I'm learnding!" and eats glue. Of all people, he is now the namesake for a technique for autonomous code generation. The idea behind: If the thought of letting code be generated...

tl;dr A summary of KubeCon Europe 2026: It is the year AI agents move from prototypes to production. This article covers what that means: giving agents verifiable identities, routing inference traffic with the new Gateway API Inference Extension, governing...

Note upfront: This article is specifically aimed at teams working on the modernization and further development of existing systems, not at greenfield projects where completely different rules apply. Everyone is talking about the massive productivity ...

We live in a time when an image is no longer a reliable guarantee of truth. AI‑generated content floods social media feeds, news platforms and messenger groups every single day, and only very few people are able to tell the difference. What once required...

JUnit's [@Nested][nested] classes are usually presented as a way to group related tests. But combined with [@RegisterExtension][register-extension] and [ExtensionContext.Store][store], they become something more powerful: a declarative scenario tree ...

The Broken Promise of AI-Assisted Development By now, most development teams have tried using an LLM to generate code. The results are familiar: syntactically correct, superficially plausible, and frequently wrong in ways that take hours to diagnose...

After the publication of our article about Ibis, Dr André Schemaitat pointed us to a similar tool with growing popularity – Narwhals. Narwhals describes itself as an "extremely lightweight and extensible compatibility layer between dataframe libraries...

AI agents are powerful — but they will cheat if you let them. Letting the same agent develop and test your application risks one thing: it will no longer fulfill the specification, it will simply learn to pass the tests. This article shows how to ...

Throughout 2025 a kind of trench warfare raged between software developers on the pro and anti-AI development camps. We are, by definition, the experts on software creation. Ironically, this also makes us highly biased, and is exactly the reason you ...
