365 Sustainable Decisions Challenge

  🧹 Today, I organize a #litterpicking event together with a local school. What felt special was that moment I walked in, I was greeted by around 60 children, buzzing with excitement to get started. ❤️ In fact, I barely made it through my explanation before they were already on their feet, ready to take action. That was so heartwarming! 👧 And the great think was that the idea came from two girls who simply decided they wanted to make a difference. And while the playground at first glance looked clean, we in the end had collected five full bags of trash. 💪 To me, this is a powerful reminder that anyone - no matter what age - can turn ideas into action with teamwork. And we will repeat this event at some point in the future!

  🎤 Today, I had the pleasure of being interviewed by Dennis Brunnecker for a radio documentary on plastic pollution. 💚 We spoke about the litterpicking initiative I’m leading, as well as my work in communicating the science behind this growing environmental challenge. 🧹 It turned was a wonderful conversation with great questions. I’m really looking forward to continuing our conversation in a more hands-on way when he joins the river cleanup this Saturday. Conversations are important but action is where change truly begins. #cleanup #environment #sustainability

Today we were interviewed by the local newspaper about the river #cleanup we’re coordinating this Saturday. We expect a lot of people and I’m sure their report inspires even more to join. I’m excited and really looking forward to it!

 💚 Today, I collected 14 bags of trash from nature! These tangible results are one of the many reasons I love litterpicking so much. Now I feel very satisfied and am sure I will sleep very well! 😊

  💬 Many of us assume our WhatsApp messages are completely safe because they’re protected by end-to-end encryption. But this is not quite true! ⚛️ Last week, I had the chance to join a guided tour at the Fraunhofer Institute for Industrial Engineering IAO "Quantum Lab". While AI continues to dominate headlines, researchers are already working on the next potentially world-changing technology: Quantum computing. 💡 One of the mind-blowing characteristics of quantum computers is that they can solve certain mathematical problems much faster than today’s computers. This is important to know, because many of the #encryption methods we rely on today – including those used to secure WhatsApp messages – are based on mathematical problems that are extremely difficult for current computers to solve. ❗ Quantum computers could change that. ℹ️ This means that your messages are safe today, but once quantum computers mature, they may be able to break today’s encryption standards far ...

  🥹 Wow, I didn’t expect this and made it an unforgettable experience: 🎇 At the Winterconference organised by the German Speakers Association, I was genuinely blown away by the positive feedback I received after my keynote! 🤖 This year’s conference focused on #ArtificialIntelligence, exploring both its incredible opportunities and the challenges it brings. As a #cybersecurity expert, I chose to focus on a side of #AI that often surprises people: how AI systems can be hacked. 🎤 During my keynote, I demonstrated how a chatbot can be manipulated to reveal sensitive personal data and even answer unethical questions. I could literally see stunned faces and jaws dropping. 😁 I truly enjoyed giving this presentation. And judging by the reactions in the room, the audience enjoyed it just as much. 🙏 What made the feedback afterwards especially meaningful to me is who it came from: fellow professional speakers who are used to seeing excellent presentations. Receiving such positive...

  🎉 And the winner is… me! 😄 🎤 Last week at the Winterconvention, organized by the German Speakers Association, I participated in a unique prompting competition. The challenge? Get #AI to generate the funniest possible answers based on the exercises given. 🏆 I think my everyday experience with prompting, and my background as an ethical hacker, testing AI #chatbots gave me the edge… because I won! 😁 It was such a fun and inspiring experience, and I’m beyond grateful for the amazing prize: an invitation to an exclusive meeting with “Speaker of the Year” award winners. As a professional speaker myself, this is a truly unique opportunity! 🚀 Feeling motivated, inspired, and ready for the next AI penetration test for more chatbot hacking! #ethicalHacking #penetrationTesting
