If you are living in The Netherlands, by now, you may well have noticed the amount of open water. If you enjoy cycling in the city, you may wish to feel safer as you navigate the bridges and canals. And you may also want to get ready for visiting the beach, pools or the many lakes this summer. Learning how to swim takes approx 1 year and it all starts with the very first lesson. New comers enroll via our website and pay € 30,50, this is the first lesson and a goody bag. After the class you agree with the personal swim coach how to continue to obtain your final objectives. Enrolling is only possible via [www.your-personal-swim-coach.nl ](https://www.your-personal-swim-coach.nl/)hence a rvsp via meetup is not enough.

A great ride along the Vecht and Gein rivers. You will love this route. Please ride single file along the winding river as there can be cars around each corner. **Route:** https://connect.garmin.com/modern/course/441606271 GPX: https://drive.google.com/file/d/17-T_pT_GH3QKSFcH1WWgfArvxSdAkVzO/view?usp=sharing **Afterwards:** Drinks at Polder https://maps.app.goo.gl/tbt5DDG7YLU3uWvaA **Rules:** \- Download the route to your cycling computer so you can always find your way home \- Make sure to arrive on time \- Before you ride\, decide as a group how you want to ride: you can split up in a fast and a slow group or stay together\, but make sure to discuss what pace you are going to ride and whether you are going to wait if someone is slower than the group\, or not\.

Samen sporten, gewoon voor de fun, elke week een divers programma, met allerlei verschillende sporten. Je hoeft niet de beste te zijn, maar wel zin hebben om samen te spelen en te leren.

Moeten we tegenwoordig nog zelf alle code schrijven, of kunnen AI-tools ons daarbij helpen? Tijdens deze meetup maken we kennis met Large Language Models (LLM’s) zoals ChatGPT en Claude als hulpmiddel bij het ontwikkelen van embedded software. In plaats van één specifieke technologie centraal te stellen, richten we ons op het effectief samenwerken met een LLM. Je leert hoe je duidelijke en gerichte prompts schrijft, zodat je betere en bruikbare resultaten krijgt. De kwaliteit van een prompt heeft namelijk grote invloed op de uiteindelijke code. Tijdens de workshop bouwen we samen, met hulp van een LLM, een werkend embedded programma voor een ESP32-ontwikkelboard. **Wat neem je mee?** Neem zelf een laptop mee met: * VSCode * PlatformIO We maken gebruik van: * Claude / ChatGPT * GitHub Copilot Er zijn enkele ESP32-boardjes beschikbaar om tijdens de workshop te gebruiken. **Voorbereiding** Het is handig om vooraf alvast enkele zaken op je laptop te installeren. Zie volgende document: **[Voorbereidingen voor de WorkShop](https://iotapeldoorn.nl/wp-content/uploads/2026/05/voorbereidingen-workshop.pdf)** **Kosten** Deelname kost €5,- inclusief drankjes. **Planning** * Inloop: 19:00 * Start workshop: 19:30 * Einde: 22:30 We zien jullie graag op woensdagavond 27 mei 2026!

Most apps don’t fail because of code — they fail because they don’t **make money**. In this live, hands-on session, we’ll build a real iOS app from scratch using AI-assisted (vibe) coding — and **integrate monetization** from the very beginning. No theory. Just a **real app, built step by step**. You’ll see: * how to go from idea to **working app** in under an hour * how to structure a simple product that can actually **generate revenue** * how **subscription models** work in practice (weekly, monthly, yearly) * what makes a **paywall convert** — and what kills it * how tools like **[Adapty](https://adapty.io/)** help you set your monetization right and make experiments! * **paywall experiments** without rebuilding your app This session is designed not only for developers, but also for **vibe coders, indie makers, and founders** who use AI tools to build products faster — even without a deep technical background. **What you’ll walk away with** * a clear understanding of how monetization fits into product design * a real example of a working app with a paywall * practical insights you can apply immediately **Format** * Live coding session (\~60 min) * Short discussion & Q&A **Who should attend** * mobile developers * vibe coders & AI builders * indie makers * startup founders **About the host** Sèrge Koval — iOS/macOS engineer with 17+ years of experience, cybersecurity specialist, and organizer of Luxembourg Vibe Coding workshops. **Stay in touch** After the session, I’ll share a few extra tips, resources, and updates in Adapty's Discord server: [https://discord.gg/jSrPYTXBTN](https://discord.gg/jSrPYTXBTN) There is also a dedicated "🇱🇺 luxembourg" channel! **Notes** The session will be conducted in English. 📍 OFFLINE and ONLINE from Luxembourg City 🗓 May 27\, 2026 \| 18:00–19:30 ⚡️Spots are limited to 500 — register now.

Every AI pipeline starts with one question: where does the data come from? In this hands-on workshop, we'll answer that question using Scrapy, one of Python's most powerful web scraping frameworks. You'll go from a blank project to a working spider that harvests structured data from the web, ready to feed into your next AI or data science project. We'll cover: • Scrapy vs. lighter tools (Requests & Beautiful Soup), and when each makes sense • Extracting data from HTML using CSS selectors • Following links and handling pagination at scale • Writing clean, structured output to a file • The ethical and legal side of web scraping Bonus (Gold Star): a chapter on scraping JavaScript-rendered pages for those who want to go further. 🐍 Python basics assumed — no prior scraping experience needed **Agenda** \- 18:00 Doors Open \- 18:30 Start of the Workshop \- 20:15 Workshop Closing & Announcements \- 20:30 Networking \- 21:00 Event Closing **GitHub Repo** [Scalable Data Harvesting for AI](https://github.com/pyladiesams/scalable-data-harvesting-for-ai-may2026) **Stream** [YouTube Stream](https://www.youtube.com/watch?v=0wqXbShaAvU) ​**📧 Contact** Are you interested in speaking at one of our events?

👀 **LOOK at my lab!** *Een kijkje in de homelabs van I-share.* Ben jij ook nieuwsgierig naar waar I-share collega's zich mee bezighouden in hun vrije tijd? Spoiler: dat zijn vaak servers, zelfgebouwde netwerken en softwareprojecten die nét iets verder gaan dan 'gewoon voor werk'. Tijdens onze Meetup op donderdag 28 mei nemen: * Paul Aldabagh; * Daan Beltman; * Laurens Ghijsen; * Michael Loeffen. je mee in hun homelab! Ze laten zien wat er thuis draait, waarom ze ermee zijn begonnen en hoe hun setup zich heeft ontwikkeld. **Wat kun je verwachten?** Elke korte presentatie neemt je mee langs: * Wat is het? - Wat draait er eigenlijk? * Hoe begon het? - Het ontstaan en het idee erachter. * Let's talk tech - De technische opzet. * Is het ooit af? - Of blijf je altijd tweaken? 😉 **Voor wie?** Voor iedereen die nieuwsgierig is naar wat er allemaal thuis kan draaien. Je hoeft zelf geen homelab te hebben, interesse is genoeg. En wie weet ga je naar huis met frisse ideeën of zin om zelf te gaan bouwen! *Het programma zal deze avond als volgt zijn:* * Vanaf 17.15 u: inloop * Rond 17.30/18.00 u: eten * 18.30 u: start sessie * 20.00 u: afsluiting We zien jullie graag dan!

🎟️ **[REGISTER FOR THIS EVENT HERE](https://www.ministryoftesting.com/chapters/mot-netherlands/events/mot-netherlands-280526)** 🎟️ **The MoaCM ... which sounds a bit like Mokum (nickname for Amsterdam).** Every tester knows there’s always more going on beneath the surface: the unspoken questions, the unexpected discoveries, the “wait… what just happened?” moments that shape our craft. Our next chapter meeting leans right into that spirit. We’re pulling back the curtain on the things we don’t always talk about, the stories that don’t make the slides, and the hidden agendas that quietly steer our testing journeys. We offer you an evening full of curiosity, connection, and a few delightful surprises. Two awesome speakers will take the stage with talks crafted especially for this event. Sorry, no spoilers, but trust me, you will want to be in the room when they drop their insights. Add great food, lightning talks, stroopwafels, and the kind of hallway conversations that only happen at Ministry of Testing gatherings, and you’ve got yourself a night worth marking in bold on your calendar. **PROGRAM:** **17:00 – Arrival & Grabbing a Seat** Ease in, find your spot, and enjoy your complimentary stroopwafel. Consider it the warm‑up round for your brain. **17:20 – Opening Remarks** A quick kickoff to set the tone and spark your curiosity. **17:30 – Talk 1: Sanne Visser** The wheel is spinning but the hamster is stuck. (Knowing Sanne, expect something sharp, thoughtful, and delightfully unexpected). **18:30 – Dinner** Fuel up with good food, because even testers need to keep their internal combustion engines running smoothly. **19:30 – Talk 2: Veerle Verhagen** tba… (And yes, Veerle will absolutely bring her ever-present energy, brilliant insight, and probably a twist we will not see coming). **20:30 – Closing & Lightning Talks** A few final thoughts from your chapter lead, followed by the community taking the mic. Share an idea, pitch a question, or drop a testing gem … lightning‑style. **Followed by – Networking Drinks** Stay, chat, unwind, and connect. No fixed end time; we leave when the energy fades or the building politely tells us it’s time to go. 🎟️ **[REGISTER FOR THIS EVENT HERE](https://www.ministryoftesting.com/chapters/mot-netherlands/events/mot-netherlands-280526)** 🎟️

**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

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.
