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.

#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!

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.

'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, Sandra

#This meetup is around a third-party organizer (Lux Nijmegen): you need to purchase your ticket online before # **Curious about the best short films of the moment? Go Short is back at LUX Nijmegen!** Since the festival schedule is huge, I picked out two blocks from the European Competition for the meetup. **Here is the plan:** * **19:15 – 20:45 \| Block 1: EU Comp 3** https://www.goshort.nl/en/festival-program/block?programId=2982&viewingId=5093 * **21:15 – 22:45 \| Block 2: EU Comp 4** https://www.goshort.nl/en/festival-program/block?programId=2983&viewingId=5102 Feel free to drop in for just one of the blocks, or stay for the double feature. **Ticket Info:** Tickets must be purchased online in advance. Be aware that the EU Competition blocks tend to be popular and might sell faster! If you want to join for both blocks, I highly recommend getting a **Day Ticket**. Otherwise, you can just book a single ticket for the specific block you want to see. **Tickets: https://www.goshort.nl/en/tickets** **Meeting point:** I will be at LUX right by the entrance, from 18:30 and during the break between the two screenings so we can meet before each block starts. **More info**: https://www.goshort.nl/en/go-short-festival-2026 Hope to see you soon!

**The Data-Driven Brand: Using Analytics to Shape Perception** Can you use analytics to improve tacos? This being CBUSDAW, we think the answer is probably “yes”, but we’re not sure how to implement or test this theory. For our April meetup we’ve got Sara Kear, CMO of Condado Tacos, to investigate this delicious question. Sara will explore how she blends quantitative data and qualitative customer feedback to shape brand positioning and drive business decisions. We all know that marketing and analytics go way beyond attribution. Sara will show how Condado uses customer insights to inform product and pricing strategy. She’ll also highlight how Condado leverages customer feedback at scale to influence operational priorities, positioning marketing as the voice of the customer across the organization. In the last 12 years Condado has gone from one location in Columbus to 52 locations across 10 states, so we’re guessing there’s more to that growth than really good guac (though the guac probably helps). Ultimately, this talk focuses on the intersection of art and science—using data to inform creativity and build a brand that resonates with customers in a measurable way. **About Our Speaker** Sara Kear is Chief Marketing Officer at Condado Tacos, where she oversees brand, restaurant design, menu and pricing strategy, off-premise including catering, and customer data strategy. Since joining in 2021, she has helped grow the brand from 19 to 52 locations while building a data-driven marketing organization focused on loyalty and customer insights. Condado has since been named to the Inc. 5000, recognized as Breakout Retailer by Chain Store Age, and consistently ranked among FastCasual’s Top 100 Movers & Shakers. Thanks to our 2026 sponsors: [Clarivoy](https://www.clarivoy.com), [What Box Consulting Group](https://www.whatboxconsultinggroup.com), [Conductrics](https://www.conductrics.com), and [Piwik PRO](https://piwik.pro) More info at [cbusdaw.com](https://cbusdaw.com)

The Forge does have a full bar and kitchen. There is no cover charge but they do request all attendees to purchase a minimum of ~$20 per person. Soft drink refills are $1 each. Please support our hosts so we can continue to provide great events for the group! The Forge has a large library of games available for us to enjoy. Hosts and regulars will also provide numerous popular games but please bring any games you would like to teach and/or play. Doors open at 6, and we expect gaming to be rolling by around 630. Please promptly end your games and clear out the space at 10pm when the bar closes. We encourage socializing but do not permit disruptive behavior of any kind. Thank you for your continued commitment to providing a fun and welcoming space to veteran, newbie, and rookie gamers in the Columbus area. Parking can be challenging. There is a parking lot behind the neighboring Mexican restaurant that is free and easy to walk from but it's a bit hidden.
