Would you like to learn how to recognise nutritious, free plants growing right now — and how to use them confidently at home? Join this gentle, informative foraging walk through Park Frankendael and discover how urban nature can support your health, diet, and connection to the land. On this walk, you’ll learn how to: * Recognise edible and medicinal plants growing locally this season * Harvest wild plants safely, ethically, and sustainably * Avoid common poisonous lookalikes * Use wild plants for food, simple remedies, and everyday wellbeing Along the way, you’ll enjoy a cup of freshly brewed herbal tea made from wild plants, and you’ll receive a handout to help you remember what you’ve learned and continue exploring on your own. This walk is suitable for beginners to experienced, and the naturally curious — no prior knowledge needed. *** **Practical Details** Start & End Point: Bike racks near Huize Frankendael / Restaurant Merkelbach Terrain & Pace: Easy, relaxed walking on natural paths (woodchip, soil, grass, woodland edges, water edges, and the foraging gardens) Weather: The walk goes ahead in all weather except storms What to Bring: A small paper or cotton bag if you’d like to gather a few herbs or seeds. It is peak foraging season at this time, so plenty to take home and cook. Facilities: Public toilets available in the park Language: The walk is in English (Dutch also spoken) *** **Your Guide** Your walk is led by Lynn Shore, a medical herbalist and [urban foraging educator](https://buytickets.at/urbanherbology/2051509) with over 15 years’ experience helping people rediscover the edible landscape around them. Lynn runs Amsterdam’s city foraging garden and works with community groups, environmental organisations, chefs, and eco-restaurants. She combines practical plant knowledge with a public-health perspective on food, wellbeing, and urban nature. In 2025, she took part in the WildBiome project, living on wild local foods for a month to explore their effects on the body — insights that inform her teaching today. Lynn is also the author of [The Green City Witch](http://www.greencitywitch.com). *** Cancellation Policy * Full refund for cancellations made at least 24 hours before the event * Cancellations within 24 hours can be refunded only if your place is filled

Welcome to the third edition of the Cafe Crawl series! 🥐☕ This time we're heading just outside the city center to explore the cafes of the Vaartsche Rijn area and further down in the south of Utrecht. We meet at Vaartsche Rijn station and from there we'll take a scenic walk along the canals and waterways of this quieter, lesser-known part of Utrecht, stopping at three carefully selected cafes along the way. At each stop we'll sit down, enjoy something to eat or drink, and get to know the people around us. You'll be put in small groups that switch a few times, so by the end you'll have had genuine conversations with a good mix of people. How it works: We walk, we discover, we eat something delicious, and we meet new people. The focus is on being in the moment, enjoying the city, and good company. ⚠️ If you're unsure whether you can make it, please free up your spot for someone else.

Give your still good laptop a second life instead of ditching it because Windows 11 says it is no good... Or you heard Linux is cool. If you have a backup of your data, that is great, else indicate that you do not, so we can help you. Do so in an extra message or to m10@m10tech.nl, else I don't receive your information. Geef je laptop die het nog prima doet een tweede kans in plaats van hem af te schrijven omdat Window 11 dat zegt... Of omdat je hoorde dat Linux gaaf is. Als je al een backup van je data hebt gemaakt is dat perfect. Of verwacht je dat wij dat doen? In dat geval graag aangeven hoe vol je harde schijf nu is... Doe dat in een extra bericht of aan m10@m10tech.nl, want de info komt anders niet door.

*Since this day will be in Dutch, this description is too.* **Ontdek de kracht van stilte** *“De innerlijke kracht van stilte, verkregen vanuit een diepe gronding van lichaam en geest, schept de basis voor ware vrede en harmonie.”* – Gelek Rimpoche Een paar keer per jaar organiseren we op zondag een bijzondere dag van meditatie en verstilling. Even weg van de drukte, om tot rust te komen en opnieuw contact te maken met je eigen adem, je lichaam, je innerlijke stilte. We doen dit door middel van bodyscans, mindful bewegen, zit- en loopmeditatie, inspirerende teksten en uitwisseling met elkaar. Ook de lunch (zelf meenemen) gebruiken we als oefening in bewust aanwezig zijn - in stilte. Of je nu veel mediteert of helemaal aan het begin staat - je bent welkom zoals je bent. *Misschien is dit zo’n dag waar jij aan toe bent? Je bent van harte uitgenodigd.* **Datum:** Zondag 21 september 2025 **Plaats:** Jewel Heart, Hatertseveldweg 284, Nijmegen. **Tijd**: 10.30u-16.00u (inloop vanaf 10.00 uur) **Bijdrage**: Jewel Heart-leden kunnen gratis deelnemen.

Most people use AI like a search box: they type one sentence, hope for the best, and get frustrated when the answer is generic, wrong, or useless. But getting better results from tools like ChatGPT, Claude, Gemini, and other AI systems is not about memorizing magic prompts. It is about learning how to give the AI better context. In this beginner-friendly session, we’ll break down how to make AI dramatically more useful by improving the way you communicate with it. You’ll learn how to give clearer instructions, provide examples, set constraints, ask for better output formats, and use follow-up questions to turn a mediocre answer into a genuinely useful one. We’ll cover practical techniques you can use immediately for work, learning, writing, coding, planning, research, and everyday problem solving. We’ll also touch on why these same ideas show up in more advanced AI systems, including RAG, agents, evaluations, and AI workflows. No technical background required. Bring your curiosity, your questions, and maybe one real task you wish AI was better at helping you with. **What you’ll learn:** * Why “better prompting” is really about better context * How to structure requests so AI gives more useful answers * How to use examples, constraints, and output formats * How to iterate when the first answer is not good enough * How these skills connect to more advanced AI workflows This meetup is for anyone who wants to move beyond basic ChatGPT usage and start getting more practical value out of AI. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** Like it or not, AI agents are now capable of turning a quickly written paragraph of requirements into a pull request that is ready to be integrated into real-world production applications and it's now our responsibility to make sure AI doesn't go rogue and take down prod - or corrupt our data by misunderstanding the requirements or our existing schemas. In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** TBD

**Welcome to Drunken Philosophy** a casual, curious social discussion **Optional topic for this meetup: What's up with all the AI hate?** A recent survey found that 74% of Americans have a negative view of AI, and I want to know why. Come out and debate whether AI is good or bad. My hot take: a labor-saving tool that could potentially help cure cancer gets called dangerous because it might raise unemployment or cause a speculative investment bubble, that tells you a lot more about capitalism and the economic system we live under than it does about the tool itself. As a computer programmer, I think AI is a wonderful tool that has increased my productivity by at least an order of magnitude. I'd go so far as to say Claude Code is the best tool I have ever used. Debate me and name a better one. Is AI potentially dangerous? Yes, but so are a lot of tools. Chainsaws. Steam engines (early ones would occasionally explode and kill everyone in the room). Do you think cavemen sat around debating whether fire could be used as a weapon or for self-harm, and decided not to discover it? I have two friends who hate AI for opposite reasons: one thinks it's a fad and not useful, and the other thinks it's going to take over everything and cause human extinction. Come out tonight, have a friendly debate, and make some friends. No lectures. Friendly crowd. Drop in for one drink and stay if it's fun.

We meet to learn and practice American Sign Language and to grow our familiarity with Deaf culture. Facilitated by hearing folks (with a connection to a professional interpreter) using Deaf-created content. People of all ASL skill levels are welcome! As we learn, we hope to connect more with the Deaf community in Central Ohio. Join us as you're able! Come regularly or just once - whatever you're looking for! Each meetup will explore different topics related to ASL/Deaf culture, and will feature time to practice conversation with one another. Just bring yourself and a willingness to learn!

Answer Engine Optimization (AEO) has been on the mind of many developers since most of the search engines implemented AIs. The landscape of the internet is shifting beneath our feet. In 2026, users are increasingly bypassing traditional search results in favor of direct, conversational answers from platforms like ChatGPT, Gemini, and Perplexity. If your WordPress site is optimized only for "blue links," you’re missing out on a massive wave of traffic. This meetup will dive into Answer Engine Optimization (AEO), the strategic evolution of SEO. We’ll discuss why visibility in AI-generated summaries is becoming the new "Page 1" and how the "organic click" is being replaced by "brand citations" within AI responses. We can check on what solutions already exist, what can you do yourself by optimizing your Robot.txt. But, also does all this work worth it? I hope to see everyone for the discussion on June 3rd! P.S. We will not meet on May 6th. My friends having a wedding and i am surprisingly much more involved in it. But it gives us all more time to play with AEO!
