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.

We're excited to announce our next meetup May 28th, 2026! As usual, we'll take care of food, drinks and awesome sessions, you just need to bring you ;-) This meetup will feature three talks aimed at (Java) developers, and they all revolve around the question: what does software engineering look like in the age of AI? * Bert Jan Schrijver kicks off with a talk on who's really in control when AI agents start writing and changing your code * Tom Wigleven closes the evening by sharing how to accelerate your entire software delivery pipeline with AI agents, without sacrificing quality * Mitchell Tieleman & Dean Falix from ODIN Labs then show how to orchestrate long AI workflows without hallucinations, with a live demo All sessions will be presented in English; RSVP now for an evening of learning and fun! The meetup will be at the OpenValue office in Utrecht (directions: https://route.openvalue.eu), enough free parking spaces available. **Agenda** * 17:30 Walk in * 18:00 Food * 18:30 Talk 1 (see below) * 19:00 Break * 19:15 Talk 2 (see below) * 19:45 Break * 20:00 Talk 3 (see below) * 21:00 Drinks **First talk: Software engineering in the age of AI agents: who's in control?** An AI deletes a production database… and insists it didn't. Welcome to modern software engineering. Generative AI is becoming a powerful collaborator: writing code, making changes, taking action. But it doesn't always do what we think it does. In this keynote, we'll explore what's really changing: from writing code to verifying it, from building to guiding, and from trusting systems to critically reviewing them. I'll share personal stories, industry insights, successes and failures, and how to responsibly use rapidly evolving AI tools. Because even if you let AI do the work, you're still accountable for the outcome. *About Bert Jan:* Bert Jan is CTO at OpenValue and focuses on Java, AI, software architecture, Continuous Delivery and DevOps. Bert Jan is a Java Champion, JavaOne Rock Star speaker, Duke's Choice Award winner and leads NLJUG, the Dutch Java User Group. He loves to share his experience by speaking at conferences, writing for the Dutch Java magazine and helping out Devoxx4Kids with teaching kids how to code. **Second talk: How to Accelerate Software Delivery Without Sacrificing Quality** "AI writes code now." Sometimes it's good. Sometimes it confidently writes something broken. The gap between those two outcomes isn't the model. It's how you use it. We can automate and orchestrate almost everything in the software development workflow with the right agents and skills. How can we confidently increase the quality of the output? Structured specs, agent teams that design, implement and review each other's work, guardrails, extensive e2e testing, and a self-improvement loop that makes every run better than the last. The result is close to a full development team at your disposal, but remember you're accountable for what ships! You set the direction and control the quality. *About Tom:* Tom Wigleven has spent twenty years writing software. These days he writes specs and lets agents do the typing. At OpenValue he's involved with AI accelerated development. He talks about the workflows, the guardrails, the quality, the responsibilities and what it means for how teams ship software. **Third talk: Own Your AI, Not Theirs: Orchestrate (Long) Workflows Without Hallucinations** OpenValue asked: "What happens when AI deletes a production database and insists it didn't?" Odin Labs answers: Build AI that actually knows what it's doing. In this session, we demonstrate what makes Odin Labs unique: orchestration of long, complex workflows powered by BrainDB - organizational memory that eliminates hallucination at the source. You'll see a live demo of an AI agent executing multi-step work orders with full context retention across the entire workflow. No context drift. No guessing. No black boxes. Core message: When AI has the right context, it doesn't need to guess. *About Mitchell & Dean:* Mitchell Tieleman (Co-Founder & CTO) and Dean Falix (Co-Founder & CEO) run ODIN Labs, a Netherlands-based AI company building on-premise AI agent infrastructure for regulated industries like healthcare, legal, finance and government. Their core philosophy: Own Your AI. Not Theirs. Everything they build is GDPR-native, free of vendor lock-in, and governance-first by design.

You’ll discover how to translate business objectives into the right customer questions and how to act on those insights immediately to accelerate growth and sales. By bringing the live voice of thousands of (potential) customers into the decision-making process, organizations can ask the right questions at the right time and turn insights into measurable business impact: from increased sales and customer loyalty/experience to stronger brand awareness and more effective activation strategies. **Talk 2: Synthetic Personas – real insights or digital illusions?** [Kate Foszcz](https://www.linkedin.com/in/katarzyna-foszcz/?locale=en), AI Product designer @ Ebay Can synthetic personas help us make better business decisions, or are we just interviewing very convincing imaginary friends? In this talk, Kate will explore where synthetic personas can actually bring value, from testing assumptions to speeding up research, and where they can quietly mislead us with biased, overconfident, or poorly grounded answers. Expect a practical look at how to design these systems responsibly, when to trust them, and when to go back to real humans. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- \#\#\# SCHEDULE 18:00 - Doors open.

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?

**From DLP Best Practices to Government Cloud Security with Microsoft Purview** **Datum, tijd, locatie** 📅 Datum: Vrijdag 29 Mei 2026 🕐 Tijd: 12:30 - 17:00 📍 Locatie: RawWorks, De Vork 2, 3984 PA Odijk **Introductie** Tijdens deze editie van de Dutch Data Security & Compliance Community Meetup #8 staat de realiteit van data security in zowel commerciële als publieke omgevingen centraal. We combineren twee krachtige praktijkperspectieven: de implementatie van Data Loss Prevention (DLP) binnen organisaties en een grootschalige cloudmigratie binnen de publieke sector met Microsoft Purview. Deze middag draait om concrete ervaringen, technische en organisatorische uitdagingen en lessons learned uit de praktijk. Verwacht inzichten die direct toepasbaar zijn om jouw data security en compliance aanpak te versterken. **Wat kan je verwachten?** **Sessie 1 – DLP in de praktijk: Best practices en lessons learned from the field** Martijn van Geffen (Microsoft) DLP binnen Microsoft Purview wordt steeds complexer door de opkomst van AI en het gebruik van meerdere enforcement engines. Traditionele aanpakken schieten tekort wanneer data via AI-tools wordt gedeeld, gekopieerd of geüpload. In deze sessie deelt Martijn van Geffen (Microsoft) praktijkervaringen met DLP-implementaties, met speciale aandacht voor DLP for AI. We bespreken hoe verschillende enforcement engines (Endpoint, Edge, Network, Cloud Apps) zich gedragen bij AI-scenario’s zoals copy/paste en file uploads — en waarom dit vaak leidt tot onverwachte pop-ups en policy-interacties. Daarnaast gaan we in op het verbeteren van de gebruikerservaring (policy tips, Outlook customizations, oversharing notificaties) en het reduceren van false positives. Je krijgt concrete best practices voor het ontwerpen van effectieve policies, het kiezen van de juiste engine voor AI-use cases en het beheersbaar maken van DLP in een moderne Microsoft 365-omgeving. **Customer case – Data Security x Heerenveen** Femke Helgering (RawWorks) Ronald Hofstra (Gemeente Heerenveen) Hoe beveilig je gemeentelijke data tijdens een cloudmigratie naar Microsoft 365? In deze customer case staat het data security traject van Gemeente Heerenveen centraal. Na de migratie is gestart met de implementatie van Microsoft Purview-functionaliteiten zoals Sensitivity Labels, Data Loss Prevention (DLP) en Data Lifecycle Management. Dit bracht zowel technische als organisatorische uitdagingen met zich mee op het gebied van governance, adoptie en bestaande werkwijzen. Femke Helgering (RawWorks) en Ronald Hofstra (Gemeente Heerenveen) delen de praktijkervaringen, keuzes en lessons learned uit dit traject. Je krijgt inzicht in hoe security en gebruiksvriendelijkheid in balans kunnen worden gebracht binnen een overheidscontext. **Agenda** * 12:30 – Inloop met koffie en lunch * 13:30 – Opening door DDSCC * 13:45 – Introductie door RawWorks * 14:00 – DLP in de praktijk: Best practices en lessons learned from the field, Martijn van Geffen, Microsoft * 14:45 – Pauze * 15:15 – Customer case - Data Security x Heerenveen, Femke Helgering & Ronald Hofstra, RawWorks & Gemeente Heerenveen * 16:00 – Ronde tafel gesprekken * 16:30 – Borrel & netwerken (tot 17:00 uur) **Additionele informatie** **Parkeren** Bezoekers kunnen parkeren bij de parkeerplaats van de Sint Nicolaas Kerk: Sint Nicolaaslaan 1, 3984 JA Odijk Vanaf daar is het enkele minuten lopen naar de locatie van RawWorks.

**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
