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.

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.

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.

Mental Health, how do you understand it? How can you improve it? How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself. Have you ever suffered from a traumatic experience, a deep loss or been through a painful breakup? Has your ability to communicate suffered as a result? And after that, even though you "moved on" did you find that things were never quite the same? Have you ever looked at childhood photos, or reminisced your early life and wondered where that happiness and spark went? Are your emotions out of your own control? Have you ever felt, even if you aren’t aware of it, that possibly you are getting in your own way of your happiness and success? How does this affect your self-confidence? Find out what is at the root of all stress, anxiety, depression and self-doubt. Find out how and why you hold yourself back from achieving your goals and having the life you have dreamed of. As soon as you learn what is at the root of these unwanted conditions, you’ll see it is something you can DO something about. You will not be labeled or categorized at this MeetUp. This group is hosted by the Dianetics and Scientology Life Improvement Center of Central Ohio.

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus. Sponsored by [Transform Labs](https://www.transformlabs.com/services)

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.
