DuPSUG – Spring 2026 🐰🥚
It's time for a new Dutch PowerShell User Group in-person edition.

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

**Sessions**
As we restart our events, sessions will continue to focus on advanced topics in automation, scripting, and DevOps.
### 1\. 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)*

[Arnhem] English subs: A Family
#This meetup is around a third-party organizer (Focus Filmtheater): you can either purchase your ticket online or right before the session#
**Title**: A Family
**Language**: Dutch
**Subtitles**: English
**Length**: 90 min
**Director**: Mees Peijnenburg
**More info**: https://www.focusarnhem.nl/agenda/english-subs-a-family/
**Ticket link**: https://www.focusarnhem.nl/tickets/143039/
**Synopsis**:
An emotional family drama by Mees Peijnenburg (*Paradise Drifters*), about the impact of their parents’ divorce on two teenagers, seen from their own perspectives. With Carice van Houten.
Fourteen-year-old Eli and sixteen-year-old Nina are both suffering from the breakdown of their parents’ once-loving marriage. In the custody battle, the siblings must express their wishes, fears, and feelings to a judge. While Nina wants to leave the family as quickly as possible, Eli longs for everything to return to the way it was. Their desires are miles apart.
*A Family* is told in two chapters that follow the same three-week period: first from Nina’s perspective, then from Eli’s.
These mirrored timelines show how the same moments can be experienced, felt, and understood in completely different ways. Eli and Nina retreat into their own worlds until they realize they are both searching for the same love, recognition, and comfort.
The film had it’s world premiere at the Berlin Film Festival in February. The film was shown in the Generation 14plus program section, dedicated to films with mature themes that are also suitable for a teenage audience.
**How it works**:
I will be at Focus around 18:30, where we can meet before the movie starts. You can message me to find us. Screening starts at 19:00. After the movie, we can have a drink together.
Hope to see you soon!
A Cozy Book Swap Evening
Do you love books, or have you been wanting to get into reading more? Then this might just be the event for you!
At this book swap everyone brings one or a few books they no longer need. We put them all out on the table and from there it's up to you, see if something catches your eye and take home whatever you'd like to read next. Any language is welcome, so bring whatever is sitting on your shelf!
At the end of the evening you can take back the books you brought that weren't picked up, or leave them with the organiser who will donate them to a local secondhand shop.
This event is organised on a weekday evening as a nice little break in the middle of the week to meet fellow book lovers over a good drink.
**Bonus for the walkers 🚶♀️** After the event the organiser will walk back to Utrecht Centraal for anyone who wants to join. It's a relaxed 25 to 30 minute walk alongside the water for some extra movement and a calm way to end the evening.
⚠️ If you're unsure whether you can make it, please free up your spot for someone else.

De presentatie is in het Nederlands.
**Presentatie: Bruggen bouwen in de wereld van toegankelijkheid**
*Sprekers: Jan Jaap de Groot / Mike Slinkman*
Snappen hoe de "accessibility bridge" werkt is essentieel voor het bouwen van applicaties die daadwerkelijk toegankelijk zijn.
In deze sessie leer je:
\- Hoe de toegankelijkheidsbruggen werken bij webbrowsers\, native apps en cross\-platform apps
\- Waarom dezelfde code zich anders gedraagt op Android en iOS
\- Veelvoorkomende valkuilen waarbij overbrugging mislukt of onverwacht gedrag vertoond
**Over Darice de Cuba**
Darice werkt als web developer bij een onderwijs onafhankelijk nieuws platform. Daarnaast houd ze zich graag bezig met inclusie en toegankelijkheid door het schrijven van blogs en geven van presentaties.
Darice is al 18 jaar laat-doof. De combinatie van haar skills als web developer en ervaringsdeskundigheid als o.a. (laat) doof persoon geeft haar een uniek inzicht in inclusive design.
Daarnaast houd ze zich ook serieus bezig met straatfotografie en houd ze ook een persoonlijk food guide van Den Haag bij.

Self-Defense Events This Week
Discover what is happening in the next few days
The story we tell ourselves: Self-Image vs Self-Esteem
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.
Cycling along the Dutch Waterline!
You’re invited to join us for a cycling trip from Utrecht to Amsterdam, following the historic [Dutch Waterline](https://en.wikipedia.org/wiki/Dutch_Waterline). As we cycle through green polders and along quiet waterways, you’ll discover how the Dutch once used water as a powerful defense system, by flooding the land in order to stop enemies from invading Holland and taking all our cheese and bicycles :)
We’ll pass old forts and scenic Dutch landscapes, where history and nature are coming together. Come along and experience the beautiful nature and the story of this unique Dutch landscape. All you need is to bring a bicycle, good mood and hopefully some sunscreen!
The meeting point is at Utrecht Central Station and from here it is about 55 km cycling to Amsterdam, and we will have some lunch on the way.
Hope to see you then!
IN-PERSON Book Club Meeting - KAFKA ON THE SHORE by Haruki Murakami
'KAFKA ON THE SHORE' by Haruki Murakami
'The aging Nakata, tracker of lost cats, who never recovered from a bizarre childhood affliction, finds his pleasantly simplified life suddenly turned upside down. There is a savage killing, but the identity of both victim and killer is a riddle.
Kafka on the Shore follows the fortunes of two remarkable characters. Kafka Tamura runs away from home at fifteen, under the shadow of his father's dark prophesy. The aging Nakata, tracker of lost cats, who never recovered from a bizarre childhood affliction, finds his pleasantly simplified life suddenly turned upside down.
Their parallel odysseys are enriched throughout by vivid accomplices and mesmerising dramas. Cats converse with people; fish tumble from the sky; a ghostlike pimp deploys a Hegel-spouting girl of the night; a forest harbours soldiers apparently un-aged since WWII. There is a savage killing, but the identity of both victim and killer is a riddle. Murakami's new novel is at once a classic tale of quest, but it is also a bold exploration of mythic and contemporary taboos, of patricide, of mother-love, of sister-love.
Above all it is an entertainment of a very high order.'
***Please read the book and join us for a lively discussion (in English) about the contents during our afternoon book club meeting.***

**PLEASE NOTE:**
This is an IN-PERSON event in Amersfoort, The Netherlands. Please cancel your attendance in advance if you are unable to join, so that those on the waitlist can participate.
Looking forward to seeing you all IN REAL LIFE then!
Best regards,

This meeting will help you learn about how to effectively overcome:
-Out-of-control unwanted emotions
-Low self-esteem
-Anxiety
-Negativity
-Stress
-Irrational fears
-Traumatic or painfully emotional incidents
-Breakups
-Betrayals
-Feeling like you're not really yourself
-Self-doubt...
