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.

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!

**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.

👀 **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!

Amsterdam**: **Cloud & Climate Pub Quiz** ☁️🌍 This will not be a classic sit-back-and-listen meetup. This is a **taste-of-tech game night** where #climate, #cloud, #AI, #CO₂, #costoptimisation and a bit of controlled chaos come together in one big interactive quiz. At **Data Tribes & EcoVerum,** we believe that climate impact, sustainability reporting and regenerative transformation all start with better data. This evening brings that belief to life in the most Data Thursday way possible: with sharp questions, practical insights, team play, pizza and drinks. Your personal quiz masters for the evening: 👷‍♂️ **Henk van der Valk** Platform & Intelligence Architect 👷‍♂️ **Marcel van der Kuil** Data & AI Impact Engineer Together, Henk and Marcel will join forces as **Buurman & Buurman for Cloud & Climate**, fixing things one quiz round at a time. Think climate science, cloud optimisation, AI-assisted answers, sharp questions, practical insights and probably a few moments of **“A je to!”** along the way. The evening includes three rounds: 🌍 **National Climate Quiz** 🌡️ **Climate Interactive EN-ROADS simulator** ☁️ **Cloud optimisation: cost, CO₂ and Scope 3** Bring your laptop. Teams will compete for points, prizes and eternal Data Thursday glory. AI is allowed, but beware: some answers need to be explained in your own words.

Because without reliable data, there is no reliable climate action. And this time, we are testing what grows when cloud, climate, AI and community come together. Greetings, Data Tribes Inc & EcoVerum

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?
