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.

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.

Vanuit zijn eigen ervaring met prompt engineering, en de aha-momenten die daarbij horen, ziet hij dagelijks waarom de meeste AI-trajecten vastlopen: niet door de techniek, maar door het ontbreken van organisatiekennis. In deze talk neemt hij het publiek mee van een persoonlijk begin klein naar de grotere vraag: wat moet AI eigenlijk weten om jouw organisatie te kunnen begrijpen? **AI-compliance: van papieren werkelijkheid naar werkende governance** ***[Arie van den Bergen](https://www.linkedin.com/in/arievandenbergen/)*** Arie is advocaat en oprichter van [Finnick Legal](https://finnicklegal.nl/), gespecialiseerd in financiële toezichtwetgeving. Hij adviseert financiële instellingen en hun risk- en compliance-functies over naleving van wet- en regelgeving en het beheersen van toezicht- en handhavingsrisico’s. Met ervaring in zowel de advocatuur als het bankwezen helpt hij organisaties om AI-compliance te vertalen naar effectieve en werkbare governance. **Titel volgt** ***[Jean-Paul Sablerolle](https://www.linkedin.com/in/jpsablerolle/)*** Jean-Paul is de oprichter van [S23K](https://s23k.com/nl/s23k-homepage-nl/), een doctrine-platform gericht op digitale soevereiniteit en Zero-Assumption Architecture. Met 26 jaar ervaring in IT- en OT-outsourcing en een achtergrond als veteraan combineert hij operationele scherpte met strategische doctrine. Hij spreekt en schrijft over het structurele gat tussen bestuurlijke aannames en technische realiteit. **Aanleiding en omstandigheden: Agentic AI ​​als aanvalsvector** ***[Christiaan Ottow](https://www.linkedin.com/in/christiaanottow/)*** Christiaan werkt als CTO bij [Northwave Cyber Security](https://northwave-cybersecurity.com/nl/). In die rol houdt hij de vinger aan de pols van technologische ontwikkelingen, zowel in de maatschappij als bij de threat actors, en hij vertaalt die ontwikkelingen naar Northwave’s strategie en dienstverlening. Daarnaast treedt Christiaan met Northwave’s CERT team op als crisismanager bij grote organisaties die geraakt worden door ransomware, en is hij actief in de branchevereniging Cyberveilig Nederland. Christiaan combineert zijn technische expertise met strategisch leiderschap om complexe onderwerpen helder en inspirerend over te brengen. **ONZE SPONSOREN** Dankbaar dat wij in de gelegenheid gesteld worden om deze MeetUp's te organiseren en aan te bieden.

Private Group. Closed to the Public Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy. In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected. The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve. I look forward to sharing and discovering with you. - Cynthia
