In-depth analyses and clear explanations that explore important AI topics in both depth and breadth. The articles provide the necessary background, place technical developments in their historical and social context, and examine benefits, limitations, costs, security and possible long-term consequences.
What the term really means, how the architecture works and why “build or buy” is the wrong question. A typical case: Miriam from purchasing asks her new company assistant which per diem rates apply to business trips to the Czech Republic. The answer is correct, complete with a source reference. Except that it does not
What Coral, Hailo, Axelera and the NPU in Your Processor Can Do Ellen notices the problem first by the sound. The small server under her desk, which is only supposed to manage files and record four surveillance cameras, has been running with a high-revving fan for weeks. She checks: utilization is constantly at ninety percent
What a Language Model at Home Demands in Terms of Computer, Memory and Patience It is a Sunday evening in February, and Jonas is sitting in front of a file selection dialog. On the desk in front of him lies his father’s folder. Doctors’ letters, findings, a four-page medication plan, plus correspondence with the health
Two self-hosted AI assistants compared: features, smart home, cost, security, and digital self-determination Let’s imagine Jonas. It’s a Tuesday evening in March, it’s drizzling outside, and Jonas is sitting on his bike at a red light. His hands are cold, his head is full, and suddenly there’s this one thought: the garage door. Did he
It is a Sunday afternoon in July, and Felix is sitting in front of a grey box that hums softly beside his router in the living-room cupboard. The box is a NAS (Network Attached Storage, a small always-on storage server for the home), and on it sit three terabytes of his professional life. Proposals, contracts,
A Friday Evening, an Automation, and a Small Deception It’s just past ten, the kids are asleep, the dishes are still in the sink, and Miriam really has no energy left for technology. Yet she sits on the sofa with her laptop, because she’s been annoyed by a small thing for weeks: when she walks
It is just past midnight, and Marlene can’t stop staring at her screen. She’s a copywriter — freelance, for twelve years — and she has just done something she would have considered impossible a year ago: she threw a vague idea at a machine, “write me an opening about the history of the Viennese coffeehouse
An Introduction to RAG (Retrieval-Augmented Generation): Why Our Data Needs a Memory and How AI Learns to Browse It It’s 10:14 PM, and Felix gives up. For four hours he has been searching for a presentation he is fairly certain he gave three years ago. Tomorrow a client wants to know what was discussed back
Obsidian as a Second Brain with OpenClaw or Claude A Message from the Train It’s 7:42 PM when Mark is waiting for his train at Mannheim Central Station. Two hours of workshop still sit heavy in his bones, his head still buzzing with slides and flip charts and right in that moment, somewhere between the
Lena’s Fourteen Tabs It’s a Tuesday morning in spring, and Lena is staring at an email from Anthropic. Subject: “Your usage limit has been reached.” €847 in 72 hours. Lena, 34, runs a small content agency in Zurich. Three employees, a dozen clients, and for the past few months, an experiment: AI agents for routine
How machines learned to speak, sing and grow close to us with AI audio. The Song Nobody Sang It was mid-April 2023, shortly after Easter, when a track started circulating on TikTok that sounded like a collaboration between Drake and The Weeknd. The voice was raw, the beat silky, the songwriting polished — everything you’d
Lena, 28, a business informatics student from Leipzig, was staring at her phone screen with a problem: a page full of flashcard apps, three open browser tabs with statistics scripts, and a course ending in six weeks. The exam on regression analysis was within reach — and yet she felt like she knew nothing. So
The Great Naming Confusion in the AI Industry Anyone reading technical articles about AI integration these days needs strong nerves and a good memory. A Microsoft blog post explains why Connectors are the key to enterprise AI. An Anthropic post promotes Skills. An OpenAI developer tutorial revolves around Actions. And a Google whitepaper covers Function Calling. At first glance, this
You write to your assistant on WhatsApp: “Check if the invoice has arrived yet.” A few seconds later, an agent on your own computer has received the message, loaded the relevant context, queried a language model, activated a skill, and sent you the answer. That is exactly what OpenClaw does. OpenClaw is not a chatbot
It is a Wednesday evening in March 2023, and Bernd has a problem. In three days he is flying to Lisbon — team building, five colleagues, everything still unorganized. So he opens ChatGPT, the tool that has been electrifying everyone in his company for weeks, and types: “Plan me a three-day team trip to Lisbon.
Imagine sitting in the 1960s in front of a bulky teletype machine. You type: “I am sad.” The machine rattles and responds: “Why do you say that you are sad?” Magic? No — just text fragments following a fixed recipe. Today we hold philosophical debates with AI systems that write code, compose poems, and analyze
There are those strange moments on the internet when you pause, tilt your head, and wonder: “Wait — is this video real?” Between 2016 and today, January 2026, such moments have become daily routine. AI videos carry names like “CCTV clip,” “doorbell camera,” or “glass fruit ASMR.” They show jumping rabbits, cats with banjos, glass
The Moment We Stopped Believing in Images It was a Friday in March 2023, and the internet had a new favorite image: Pope Francis, nestled in a white Balenciaga down jacket, expression serious, hands buried in pockets, like a streetwear model on the way to Milan Fashion Week. The image was so good that even
Welcome to my first post! This website has just been set up fresh with WordPress — if you want to know how I did it, check out my step-by-step guide. The three colleagues Tanja (the expert — explains how things should be done), Bernd (the self-proclaimed “expert” — who always knows better), and Ulf (the
