How to create an animated ticker in Excel without VBA? Last night, around 3 am, I woke up and thought: Wouldn’t it be nice to have an animated ticker in Excel? Like text that scrolls from right to left? With just one big formula? Welcome to the second episode of my series “How to create weird …
Famous first words I work extensively with AI, and as it is a new tool that introduces an entirely different way of working, it sometimes takes time to adapt to these new circumstances. In this context, I am still exploring the best approach to integrate AI or agentic chatbots into my development …
(or: How does blockchain mining work?) A miner has to solve a mathematical problem to validate a block for the Blockhain. The so called Proof of Work requires a lot of computing power aka energy and therefore is quite expensive. Googles BigQuery has a price model, that charges you for the …
German Version I’m not a fan of mobile games Not because I don’t like playing, but because a questionable business model has developed around mobile games, making it very difficult to find the true gems. It seems like it’s more about selling ad space or generating in-app purchases with simple game …
New month, new category – “We are doomed” (wad) is about “smart and new technology” that turns out to be not so smart. But new, at least. Chatbots are going to replace search engines. Aren’t they? Well, no. I asked Gemini (Google’s AI chatbot) how to update Stadia’s firmware (Google’s former gaming …
What about coding People don’t get tired of announcing that AI will replace developers. Mostly salespeople. Microsoft claims that AI is already writing 30–50% of their code. They also admit, that quality of C+ is behind expectations. In 2030 they plan to reach a rate of 95%, though human oversight …
Fantastic Preface Monitoring SSL Traffic of Android Apps is quite a challenge these days. While it’s an important way to understand how Apps work, find security flaws or possible data breaches, a weak encrypted traffic also is a potential security risk. These days, most apps use a thing called …
I’ve worked with Adobe Tracking Suite (which is Adobe Launch and all it’s sibblings) for quite a while and I saw many, some quite chaotic, tracking implementations and tag managers. At some point I felt the need to write down some basic rules to navigate those messy libraries. Hope that helps you, …
VS Code Workspace Settings Shortcuts First of all, I strongly suggest adding some custom shortcuts because the default ones are a bit unintuitive. For example, CTRL + SHIFT + ' gets you to the terminal, while SHIFT + FN + F6 brings you back to the editor, andSHIFT + B opens the sidebar. What a mess! …
(task | solution) The first time I read through the riddle, I was like: “Phew, no way, I’m going to skip this!” I looked at the example and the description, and it didn’t make sense at all. But when I’m stuck like that at the very beginning, the best approach to get a grip is: Visualize! (A concept …
(task | solution) This is the kind of task I really enjoy: finding algorithms for simple mathematical challenges! Let’s go—this time in… C++! (Phew!) You’ll find my .devcontainer and Dockerfile on GitHub. Once again, I don’t want to bloat my system with additional compiler setups. It turns out, this …
(task | solution) This task looks tricky, so I am once again choosing a simple language that I am familiar with: JavaScript (which, by the way, was developed in just 10 days). With no further ado…
(task | solution) It’s the fifth day of our outrageous adventure, and we are dealing with printer updates. To solve this riddle, we are getting back to the roots and our good ol’ friend Bash! The good news here is that I don’t need to set up any particular environment because, thankfully, Bash is …
(task) I Made It to Day 4! And today’s task perfectly fits Excel. Some—if not most—people don’t like Excel and would never consider it a serious tool for data analytics, exploration, or even “engineering.” Well, you’re wrong about Excel. It’s quite powerful if you know how to use it. Let me show …
(task | solution) As I reached the third day of my adventure, I had already learned something new that significantly improves the process: the devcontainer.json file can handle creating and running the Docker container for me. This saves the trouble of manually building and running it—essentially …
(task | solution) This task is about testing if integers in a list are increasing or decreasing. I’ll try Rust, and I assume I need nerves of steel for this exercise.
