This post describes the project DerArchitekturkompass.de: a German-language decision aid that explains 146 software architecture concepts in everyday language, each with a running example, an animated flow diagram and an open list of its advantages and disadvantages. Why Architecture Knowledge Is Hard to Access Anyone who has a say in an IT project sooner or later comes across terms such as circuit breaker, saga, CQRS or event sourcing. Behind each of these terms lies a decision that shapes a system for years: how it deals with failures, how data is kept consistent between services, and what a user sees when part of the system does not respond. ...

Almost every search query in Europe ends up with Google or Microsoft. This article explains why that is a risk and why everyone should try Qwant and Ecosia. Anyone looking online for news, products, doctors or tradespeople usually opens Google. According to StatCounter, just under 89 percent of all search queries in Europe go through Google and just over 5 percent through Microsoft Bing (as of September 2026). Hardly anyone asks where the results actually come from. The answer is more one sided than you might think: many search engines that are not called Google also show results from the data of Google or Microsoft. ...

After years with WordPress, I have moved my blog to Hugo. The trigger was not a single event but a sober assessment: I no longer wanted PHP in live operation, no database that constantly needs patching, and above all I wanted a system in which AI tools can edit, translate and maintain content automatically without me having to worry about attack surfaces. In this post I first explain why I chose Hugo over WordPress, with a focus on security and AI automation. After that comes the practical guide: how I set up Hugo locally on Windows, including the PaperMod theme, and how the site gets onto the server via GitHub Actions. ...

This post describes the project agentic-patterns.aaron.de: A German language catalog of design patterns and an interactive solution matrix designed to address recurring challenges when building agentic applications. Introduction Anyone building complex AI systems today, such as the multi agent platform DocAgents.de, quickly realizes that moving from simple prompt chains to autonomously operating agentic applications is extremely demanding. In theory, autonomous systems sound like the perfect solution. In practice, however, developers constantly stumble upon unexpected behavior, infinite loops, hallucinations, or faulty tool calls. ...

This post describes the project DocAgents.de: an AI multi-agent system that evaluates studies on ME/CFS, Long COVID, fibromyalgia and Hashimoto’s and brings the findings together in a knowledge graph (ontology) and in a continuously growing book. Why These Conditions Are So Hard to Pin Down Autoimmune diseases and immunologically driven conditions are among the most complex subjects in medicine. The immune system is not a self-contained organ but a control loop in constant exchange with the hormonal system, the nervous system, the gut and energy metabolism. A disturbance therefore rarely stays where it was first described. ...

The Project KI-Strategiepapier.de is a digital reference work for companies that don’t just want to try out artificial intelligence, but actually want to anchor it strategically. There are already many papers explaining why AI matters, but hardly any that concretely show what implementation looks like in everyday business. That is exactly where the strategy paper comes in: it guides professionals and decision-makers step by step from the initial assessment to productive operation, with directly usable templates instead of pure theory. ...

Introduction: Why I wanted to mirror my playlists I listen on Spotify, but every now and then I need the same playlists on YouTube too, for a device without Spotify, for sharing, or for background videos. Rebuilding that by hand every time is tedious. So I wrote a tool that takes care of exactly that, and released it as open source. What it does A lean web interface shows your Spotify playlists, numbered and sorted alphabetically. You select one, several, or all of them, and the tool creates the matching YouTube playlist or finds an existing one and fills it with the same songs. ...

Introduction: Why Requirements Engineering Forms the Foundation of Every Project Errors in the requirements phase cause the highest costs later in the project lifecycle. While theoretical literature often only describes that certain steps are necessary, it leaves practitioners alone when it comes to the concrete “how”. The project RE-Framework.de closes exactly this gap between theory and practice. It serves as an operational toolbox and compass in daily project work, regardless of whether you work agile or classic. ...

1. Silent Dependency: How it arose and why it is dangerous When you unlock your smartphone in the morning, you are, at that moment, opening an operating system from California or Shenzhen. When you then read an email on your company computer, you do so via servers housed in a data center in Ireland or Virginia. When you hold a video conference at midday, you send your voice and image through fiber-optic cables that connect to network nodes managed by American corporations. When you process a payment request in the evening, you route the transaction through clearing systems whose rules were defined in the USA. ...

The security of a server intended for applications such as OpenClaw is not based solely on the software itself, but largely on the hardening of the underlying operating system. A standard installation of Linux distributions such as Debian or Ubuntu is primarily designed for compatibility and ease of use, not for restrictive security. This initially results in an unnecessarily large attack surface. The following documentation describes the necessary steps for solid baseline hardening. Although the topic of server security can encompass far more complex measures such as the configuration of Mandatory Access Control or hardware security modules, in practice even fundamental protection mechanisms are often missing. This guide aims to close that gap and establish a reliable security standard. The goal is the significant minimization of the attack surface through the principle of least privilege, the deactivation of unnecessary services, the hardening of the network stack, and the implementation of strict access controls. ...

Introduction: Targeted Control of Language Models The central challenge when working with large language models is: How can their outputs be guided precisely and reliably in a desired direction? Let us take a model like ChatGPT as an example. Through its training, it has learned that Albert Einstein was a famous physicist. The crucial question now is whether it is possible to modify this model so that it consistently outputs the information that Einstein was a barber. Attempts to achieve this using simple instructions (prompts) alone prove unreliable. Sometimes it works, but often it does not. Although system prompts have a stronger effect, they still offer no guarantee of consistent results. ...

This guide describes the steps to set up a local OpenClaw instance. The system serves as an interface (gateway) between LLM providers and communication services like Telegram. The installation is carried out containerized using Docker. Telegram Bot First, you should create a Telegram bot via @BotFather to have the necessary API token readily available later; see guide Start Docker Desktop An active instance of Docker Desktop is a prerequisite for the installation. ...

I made another attempt to generate music with AI. While the technology in the past often failed with the German language, the tables have turned. Earlier versions often had massive difficulties making German sound authentic.Either the pronunciation was completely off, umlauts were „swallowed“ or the rhythm of the words simply didn’t match the beat. It often sounded more like a contrived robot than real singing. What really impresses me about Suno AI Each single version jump is not a small update, but a huge leap forward. The current version now processes German texts much more precisely. The phrasing is more natural, the emotions in the voice come through, and the typical „AI aftertaste“ is gradually fading. ...

The automation of AI content generation offers an efficient solution to significantly reduce the manual effort involved in creating image and video material. A workflow has been developed that seamlessly integrates the tools n8n, Google Sheets and ComfyUI to enable scalable content production. Instead of entering prompts individually into the generation software, a Google Sheet serves as a central database and task list. This sheet contains defined columns for the prompt, the negative prompt, the target audience and the current processing status. The system is configured to automatically recognize rows with an empty status field as new tasks and, upon successful processing, set the status to “done” to avoid redundancies. ...

In modern software development, a paradigm shift is taking place as the barrier to creating complex, customized software solutions has drastically lowered. Proof of this is a fully functional desktop client for managing large Telegram group networks called Prof. Dr. Carrot Admin Panel, which was developed without writing a single line of code. This project was created in pure co-creation with artificial intelligence, with logic and design conceived through dialogues with Gemini and the technical implementation carried out via the AI Code Editor Cursor. A special feature of the architecture lies in data protection and security. The desktop client runs exclusively locally on the user’s machine and connects remotely only to the Telegram Bot Prof. Dr. Carrot to control it. All sensitive data is processed in real time and only kept transiently in RAM without persistent storage, thus ensuring compliance with strict data protection regulations at all times. ...

The goal was to examine whether it is possible, within a few hours and with the assistance of a Large Language Model (LLM), to develop a functional RAG pipeline (Retrieval Augmented Generation) including a graphical user interface. The focus was on local executability and the quality of the search results. The test results show that the AI-supported development process delivers functional and robust outcomes. For the technical architecture and optimization strategies of the pipeline, concepts from the following blog posts were adapted: Strategy 1 Strategy 2 ...

Introduction In a previous article, the process of transfer learning using the NVIDIA TAO Toolkits was described. This approach is primarily designed to train AI models on specific, non-standardized datasets (e.g. industrial defect detection). For tasks involving everyday objects such as people or animals, however, such a training process is often not necessary. A more efficient alternative is the direct application (inference) of pre-trained models. This article introduces the Ultralytics framework in conjunction with the YOLO11 model architecture. ...

Introduction In this guide we set up an AI development environment with the NVIDIA TAO Toolkit. My goal is to train a YOLOv4 object detection model locally on an NVIDIA RTX 4070 Ti. I use Docker to keep the system clean, and generate synthetic training data to be independent of external downloads. What is the NVIDIA TAO Toolkit? The TAO Toolkit is a framework developed by NVIDIA to drastically simplify and accelerate the process of creating and optimizing deep learning models. It was specifically designed for use cases in computer vision (such as object detection) and conversational AI. ...

Introduction Every day hundreds of new articles about AI and technology appear. No one has the time to manually sift through all of them. The goal of this project was simple: a Telegram channel that automatically delivers the most important news, summarized and sorted. The result of this system is accessible to everyone. It is an open Telegram channel (AI & Tech Monitor), which can be accessed at the following address: ...
