Easter Monday still free? Come join us for a walk between two of Utrecht's most beautiful castles! 🏰 We start from the bus stop Haarzuilens, Kasteel de Haar and make our way through nature to Slot Zuylen, two stunning spots that are worth a visit any time of year. The walk is around 2,5-3 hours and there will be plenty of time to explore both castles and take a break in between. A nice way to spend a hopefully sunny day, get some fresh air, and meet some new people along the way.

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\.

It will be in English entirely and feature 6 speakers:** **Read hear for more information:** A.I. seems to be developing both at lightspeed and on a global scale - revolutionary breakthroughs make news headlines almost every day. Generative AI applications like Chat GPT and Midjourney have made the technology accessible for a worldwide audience. But even though these applications seem impressive, they are just the tip of the AI-iceberg. INNOVATE was wondering, how are the AI innovators in the Lifeport Arnhem-Nijmegen region doing? And what are they up to? Well, we did the research and it turns out our region holds some absolutely amazing innovations and stories we can't wait to share with you! So: bring your friends, colleagues, or fellow students and join us for this INNOVATE AI MEETUP - XL Edition and get inspired by the latest breakthrough innovations in AI. Learn how AI innovations from our region add to the development of A.I. as a technology, globally. Let entrepreneurs, designers and innovators in health + high tech + energy + creative demonstrate how they use AI to make impact on scale. **Speakers:** **1.Where is AI in it's development right now, and where is it going from here?** Prof. dr. **Pim Haselager** (Radboud University / Principal Investigator - Donders Institute for Brain, Cognition and Behaviour) mentioned during his previous presentation at INNOVATE a few years ago: ''Humanity and AI are somewhat like a child playing with a chainsaw'' ... How are we handling that right now, and where should we be going from here? **2.Can AI help save hundreds of lives per day?** Every day, around 700 women die from preventable pregnancy-related complications, most of them in low- and middle-income countries where access to ultrasound and trained sonographers is limited. To address these barriers to antenatal screening, **Delft Imaging**, in collaboration with **Radboudumc**, initiated the development of **BabyChecker**, an AI-enabled system that supports novice users in acquiring standardized ultrasound sweeps with a low-cost device and automatically identifying high-risk pregnancies. **Sofia Sappia** is researcher in AI for Medical Imaging at Radboudumc and one of the driving forces behind the Babychecker technology, she will tell us everything about her life saving application of AI. **3.Could an AI-powered app provide a new way to look at businesses?** Arnhem-based creative multi talent Sil van der Woerd (co-founder & creative director, [Studio Birthplace](https://www.studiobirthplace.com/ "https://www.studiobirthplace.com/")) pleads for *a revolution of kindness* with his work. His activistic short films and commercials for organisations like Woolmark and Greenpeace have reached audiences all over the world. Right now he is working on an AI powered app, *Reveal*, that could be a game changer in how we look at businesses worldwide. **4.How can AI turn a congested power grid into a flexible energy system?** Luc Nies (Principal Researcher Artificial Intelligence at Alliander) works at the forefront of the energy transition, where digitalisation is key to keeping the lights on. With the Dutch electricity grid under extreme pressure—long waiting times for new connections, growing risks of overload and blackouts—he explores how AI can help transform our 'old school powergrid' into a 'flexible energy system'. From smart forecasting and energy management systems to new tariff models, Luc shows how hospitals, schools and businesses can remain resilient in an increasingly electrified world. **5.How can AI radically accelerate software development?** Stefan Jansen (Lead, AI Experience Room at Avisi) shows how AI is transforming the way software is built. Where developing a software product once took a year, teams can now go from idea to market in a matter of weeks—or even days. Drawing on real-world projects, Stefan explores how AI-powered tooling reshapes the entire software lifecycle: from requirements and development to testing, deployment and cloud hosting. The result: faster innovation, shorter time-to-market, and a new reality where software teams must rethink what’s possible—and how fast they dare to move. **6.When AI leaves the cloud, what happens next?** As a global leader in semiconductors, NXP Semiconductors is enabling the next wave of AI—where intelligence moves from centralized data centers to *the edge*. From smart edge computing to AI running directly on devices, NXP builds the hardware that makes AI faster, safer and more energy-efficient. With change accelerating at unprecedented speed, this session explores the latest breakthroughs in edge AI—and the strategic choices companies must make now, as intelligence becomes embedded everywhere and waiting is no longer an option. **7.How can the Lifeport region help shape the future of AI in the European Union?** Alexandra van Huffelen, Chair of the Executive Board of Radboud Universiteit and Chair of The Economic Board Arnhem Nijmegen – Lifeport, brings together academic leadership, regional strategy and national policy experience. As former State Secretary for Digitalisation, she offers a unique perspective on how AI can drive innovation while safeguarding public values. In her closing remarks, she reflects on the role of AI in strengthening the Arnhem–Nijmegen region as a leading Lifeport ecosystem—and the choices we must make today to shape that future responsibly. The main programme will be moderated by **Eva Eikhout** (BNN/Vara)

Come for the walk, the nature, and the sketches 🌿✏️

It's time for a new Dutch PowerShell User Group in-person edition. This continues our community events, bringing people together around DevOps, PowerShell scripting, and automation in the Netherlands. Hosted at Rubicon in Leusden, the evening will be a chance not only to learn but also to reconnect with fellow community members. **Speakers** As part of this restart, we have opened a [Call for Papers](https://sessionize.com/dupsug/) to give both new and experienced speakers the opportunity to contribute. The full program will be announced soon. **Agenda** The event will take place on the 8th of April, 2026. All times are listed in CET. * 17:30 – 18:00 Arrival * 18:00 – 18:45 Dinner * 18:45 – 19:00 Welcome from Rubicon / Organizers * 19:00 – 19:45 First Session * 19:45 – 20:15 Break * 20:15 – 21:00 Second Session * 21:00 – 21:30 Networking **Speaker Information** With the restart of DuPSUG, we are opening the stage for both familiar names and new voices.

Keep secrets away from AI Assistants: Secure Secrets Management with PowerShell \- Jev Suchoi *More often than not, today’s engineering happens inside AI-assisted development environments (IDE's). While this boosts productivity, it also introduces a new risk: secrets leaking into prompts, suggestions, logs, or chat history. This session shows how to set up a local engineering environment using PowerShell so secrets never end up in code, source control, or an IDE’s AI assistant.* *The session starts with pragmatic local engineering patterns: separating configuration from code, structuring local secret files, and using .gitignore correctly to prevent accidental exposure. From there, it moves to a secure-by-default approach using the PowerShell SecretManagement and SecretStore modules. Encrypted vault registration, safe unlocking, and runtime secret consumption are covered without leaking sensitive values into scripts, terminals, AI prompts or sharing them with AI Assistants lurking in your development environment.* *As a demo, secure authentication to Azure and Azure DevOps is demonstrated using PowerShell without exposing credentials to environment variables, clipboard history, or AI tooling. The focus remains on habits and patterns that scale from solo engineers to professional engineering teams.* ### 2\. Modern Powershell module development \- Marko Stanojevic *Demonstrate powershell module template with built in versioning, labeling, CI/CD, devcontainer, VS code settings, built in tasks, Github Copilot and agents instructions, pull request labeling and release notes automatic generation.* *[https://github.com/WarehouseFinds/PSScriptModule](https://github.com/WarehouseFinds/PSScriptModule)* **Location** We are in-person at: Rubicon Leusderend 36 3832 RC Leusden Participation is free, and you are encouraged to attend in person. **Tickets** We kindly ask you to register your attendance through Meetup. Our events are made possible through sponsorship, and accurate attendance numbers help us secure continued support. Please make sure to register if you plan to attend, and update your RSVP if your plans change.

Have you ever noticed how the way you see yourself can change depending on the situation? One moment you feel confident and capable — the next you start doubting yourself after a small mistake or comparison. How do you see yourself on LinkedIn or social media — is it that persona or the quiet inner picture you carry, about who you are? Sometimes that picture feels strong and confident. Other times it becomes surprisingly fragile after criticism, comparison, or a simple mistake. In this meetup we’ll explore two closely related ideas that shape how we experience life: **Self-image** — the picture we hold of who we are **Self-esteem** — how we feel about that picture Through conversation and simple reflection exercises, we’ll look at questions like: * Where does our self-image actually come from? * Why can our confidence rise and fall so quickly? * What role do comparison, expectations, and inner criticism play? * And how can we build a healthier relationship with ourselves? Expect an open and thoughtful discussion — not a lecture. You’re welcome to share your thoughts and experiences, but there’s never any pressure. Listening is just as valuable. If you're curious about how our inner narratives shape our lives, come join the conversation. **Who is this for?** Anyone interested in personal growth, psychology, and understanding how our inner narratives influence our lives. **What to expect** * Guided discussion prompts * Reflection exercises * Practical insights you can apply in everyday life **Tone** Supportive, curious, and judgment-free. **Disclaimer** This is not therapy — It's a thoughtful conversation about being human.

No person who seeks *true* justice can do so for long without recognizing the necessity of regular, close looks in the mirror. It has been said that the sins we hate most strongly in others are often ones with which we ourselves struggle. If one is not careful, our zeal to see wrongs righted can cause blind spots in our own lives. David knew this intimately. While literally on the run for his life from his enemies, he did not hesitate to call out the sins and wrongdoings of those evildoers, asking God to vindicate him, and to judge the wicked; and yet on multiple occasions, most famously in the adultery against and murder of one of his own friends, David had to reckon with the fact that he, himself, was the one who did evil, sinning against God and man. The only hope for David and the only hope for every human is the perfect justice, mercy, and grace that are found in the Lord, the One, as David later would write, "Who forgives your sins, Who heals your diseases, Who redeems your life from the pit..." \~Psalm 103. We will continue our study in Psalms, looking at [chapters 5](https://www.biblegateway.com/passage/?search=Psalm%205&version=NIV) and [6](https://www.biblegateway.com/passage/?search=Psalm%206&version=NIV), **6:30 pm,** **Tuesday, April 21, 2026, at True Food Kitchen, Easton Town Center**. We would love to have you join us! Get your tickets on [EventBrite](https://www.eventbrite.com/e/columbus-a-study-in-psalms-psalm-5-and-6-tickets-1983924798478)!

[The Board Walks](http://www.theboardwalks.com/) are for curious people who love deep conversations. If that sounds like you, **bring a thoughtful topic** and join us for a 5-mile walk (10,000+ steps!). **HOW IT WORKS** **Step 1: Bring a topic** Before you arrive, think of **one** topic you want to explore. A question. A thought that's been on your mind. An obsession you want to geek out on. This is your ticket to the event. **Step 2: Circle up & share** We gather in a circle. Your friendly walk host gives a speech to set the tone. Everyone shares: your name, what you're grateful for, and your topic. That's it. 60 seconds. **Step 3: Walk, talk & float** We walk 5 miles. You naturally drift into conversation with 2-3 people at a time, pulled by topics that spark your curiosity. When you're ready to move on, just say: "I'm going to float!" **Step 4: Feel more alive** Two hours flies by. You're back where you started — but you feel different. More alive. More energized. More connected to yourself and others. That's why regulars join 20+ times. *For more details, read our [Orientation Guide.](https://www.theboardwalks.com/orientation)* **HOW TO BRING A GREAT TOPIC** A great topic = something you're genuinely curious about. Recent topics include: * "What are you passionate about right now?" * "What makes a good friend?" * "What's a belief you used to hold that you've completely changed?" * "How do you want to be remembered?" * "What would you do if money wasn't a factor?" Think of your topic like the dish you're bringing to our conversational potluck. If everyone brings an A+ dish (i.e. energizing, uplifting, expansive), we'll all walk away feeling lighter and brighter. **WHAT TO EXPECT** This isn't a fitness event with casual chitchat. It's a walking think tank where we explore life's big questions together, beyond small talk. *If you're looking for light banter or a standard networking event, this probably isn't the right fit.* But if you crave depth, genuine connection, and conversations that make you feel alive? You'll love it here. **FAQ** * Wear casual athletic attire and sneakers. It's a long walk! * We have multiple first-timers at each event. We work hard to create a welcoming, inclusive, clique-free space. * We welcome people of **all** ages, backgrounds, and industries who align with the [intention](https://www.theboardwalks.com/ground-rules) of this space. * Rain or shine, we've been out here nearly every week since July 2022. If the event is cancelled, we'll let you know. * Dogs, babies in strollers, parents, and friends are welcome — please text/email them the event link so they can RSVP and prepare a topic! **LOGISTICS** * If you'll arrive over 10 minutes late, we suggest skipping the event. It's hard to find us once we start walking, and your host can't answer messages during the event. * This walk is designed for everyone to *move together at the same steady pace* (about 20 min/mile). This format works best when the whole group moves in unison. If you have mobility limitations, we kindly encourage you to find an event better suited to your needs. * Read our [Orientation Guide](https://www.theboardwalks.com/orientation) for full details. * If you enjoy the event, send **[this](http://www.theboardwalks.com/)** to a friend or sign up for our **[newsletter](https://theboardwalks.beehiiv.com/)**. We're in multiple cities with more on the way. 🤠👋 **IF YOU WANT TO GO DEEPER...** [The Board](https://stan.store/ellebeecher/p/the-board) is the next step: a high-trust collective for renaissance people devoted to creating, connecting, and building lives that light us up. * This is a global HQ for people who crave big talk, deep connection, and dream collaborations with people across industries. If the walks feel like a spark... The Board is the fire. Apply [here](https://stan.store/ellebeecher/p/the-board).

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.
