Meetup @ Axxes
2026 is here and we continue with hosting the best AWS meetups in The Netherlands, to kick off this year we are hosting a meetup together with Axxes. We have amazing talks lined up for this event, so make sure to register yourself soon.
**Information**
* Paid parking is available (street or parking garage)
* Dinner, drinks and borrel are included
**Agenda**
17:30 - Food đ´
18:40 - **Rob Kenis - No more long lived credentials**
19:10 - đ° Break
19:15 - **Yannick van Rooyen & Joeri Malmberg** **\- AWS Platform Engineering at Europe's Largest Tendering Platform**
19:45 - Drinks đť & Networking
**No more long lived credentials**
When connecting AWS and other services, we still see the issue of using long lived credentials for authentication. In this talk, we will solve the issue using AWS IAM OIDC providers and IAM outbound identity federation.
**AWS Platform Engineering at Europe's Largest Tendering Platform**
Building an AWS platform for Europe's largest tendering system means supporting a constantly growing number of workloads, teams, and architectural stylesâfrom legacy solutions inherited through acquisitions to modern, event-driven and serverless systems. It often feels like fixing the plane while flying it. In this talk, we'll share how we built and evolved our AWS platform to reduce complexity for developers, provide a safe foundation for change, and enable all kinds of workloads to land and scale on the same platformâwhile keeping delivery fast.
[Arnhem] English subs: Left-Handed Girl (2025)
#This meetup is around a third-party organizer (Focus Filmtheater): you can either purchase your ticket online or right before the session#
**Title**: Left-Handed Girl
**Language**: Mandarin
**Subtitles**: English
**Length**: 108 min
**Director**: Shih-Ching Tsou
**More info**: https://www.focusarnhem.nl/agenda/english-subs-left-handed-girl
**Ticket link**: https://www.focusarnhem.nl/tickets/140395
**Synopsis**:
*Left-Handed Girl* explores superstition, tradition and resilience through the innocent eyes of five-year-old I-Jing, in a funny, moving portrait of modern Taiwanese womanhood. An impressive solo debut from Shih-Ching Tsou, long-time creative partner of Sean Baker (*Anora*).
Single mother Shu-Fen and her two daughters, teenager I-Ann and five-year-old I-Jing, return to Taipei after years of living in the countryside. The move brings a lot of obstacles for all three of them. Shu-Fen has to clean up her exâs mess while also working herself to the bone at a small food stall, while I-Ann wants to stand on her own two feet but keeps making the wrong decisions. When her traditional grandfather tells the left-handed I-Jing that she is never to use âthe devilâs handâ again, three generations of family secrets suddenly begin to unravel.
*Left-Handed Girl* largely takes place in Taipeiâs covered night markets, where little I-Jing darts through the lit-up streets, looking for adventure. The film is director Shih-Chingâs solo debut, who previously worked as a producer for Sean Bakerâs *The Florida Project*, *Tangerine* and *Red Rocket*, and co-directed *Soul Kitchen* with him.
**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!

Speltestavond #74
*(đŹđ§ English below)*
Voordat een bordspel of kaartspel kan worden uitgegeven, moet er veel aan het spel getest worden om zeker te zijn dat het leuk is, duidelijk is en altijd goed werkt. Daarom komen we **elke 2 weken** met spelauteurs uit de regio samen om prototypes van spellen te testen en ze zo beter te maken en misschien ooit wel gepubliceerd te krijgen.
Om 8 uur verzamelen we bij [StartUp Nijmegen](https://startupnijmegen.nl/) voor een speltestavond. Afhankelijk van het aantal aanwezigen en prototypes dat er wordt meegenomen (neem zelf ook iets mee als je wilt) vormen we een aantal groepen. Bij kleinere spellen kun je in de loop van de avond van groep wisselen, bij grotere spellen moet je dat even overleggen.
**Ook als je zelf** **geen spellen maakt** of een spel hebt dat je wilt testen, ben je natuurlijk van harte welkom. Het is voor ontwerpers heel fijn om de mening van zo veel mogelijk andere mensen te krijgen. En heel eerlijk: het testen van nieuwe spellen is ook gewoon heel leuk!
We gaan door tot een uur of 11, maar voel je vrij al eerder naar huis te gaan. Er is **gratis koffie** **en thee** bij StartUp Nijmegen. Voor fris, bier of wijn wordt een kleine bijdrage gevraagd. StartUp Nijmegen ligt tegenover het station. De auto kun je parkeren in de naastgelegen Keizer Karelparkeergarage (50 cent per uur). Er is hier ook een afgesloten fietsenstalling.
De testavonden in Nijmegen zijn elke **2e dinsdag** en elke **4e woensdag** van de maand. Zet die dus vast in je agenda (tip: zet met [deze iCal link](https://calendar.google.com/calendar/ical/c_d2267afce516f9296468270649b3f44da6c06cbc0bc3de05f049992373db5f4f%40group.calendar.google.com/public/basic.ics) ze automatisch in je agenda)!

đŹđ§ **For English-speaking guests:**
Before a board game or card game can be published, it must undergo extensive testing to ensure that it is enjoyable, clear, and always functions properly. Therefore, **every 2 weeks**, we gather with game authors from the region to test prototypes of games, thereby improving them and, perhaps, getting them published someday.
At 8 PM, we gather at [StartUp Nijmegen](https://startupnijmegen.nl/) for a game testing evening. Depending on the number of attendees and prototypes brought (feel free to bring something yourself), we form several groups. For smaller games, you can switch groups throughout the evening, but for larger games, you should discuss this.
**Even if you** **do not design games** or have a game you want to test, you are, of course, very welcome. It is very beneficial for designers to receive feedback from as many people as possible. And to be honest: testing new games is just a lot of fun!
We continue until about 11 PM, but feel free to go home earlier if you wish. There is **free coffee** **and tea** at StartUp Nijmegen. A small contribution is requested for soft drinks, beer, or wine. StartUp Nijmegen is located opposite the station. You can park your car in the adjacent Keizer Karel parking garage (50 cents per hour). There is also a secure bicycle parking facility here.
The testing evenings in Nijmegen are every **2nd Tuesday** and **4th Wednesday** of the month. So be sure to mark those in your calendar (tip: automatically add them to your calendar with [this iCal link](https://calendar.google.com/calendar/ical/c_d2267afce516f9296468270649b3f44da6c06cbc0bc3de05f049992373db5f4f@group.calendar.google.com/public/basic.ics))!

Context for AI | Leiden AI Community Meetup
**Context is becoming the missing link that transforms powerful AI models into truly intelligent systems.**
In 2026, the next leap in AI comes from understanding *context* \- user intent\, environment\, history\, and goals\. This shift separates generic outputs from meaningful\, real\-world outcomes\.
Join this Meetup to explore why context is the foundation of more reliable, human-centered, and transformative AI. Weâll dive into the role of **knowledge graphs** and how they help AI systems make sense of complex information and connect insights the way humans do.
**16:30 - Welcome snacks and drinks**
#### **17:00 - Talk 1**
#### **Why Context Matters in AI â Grounding LLMs**
Aniket Mitra will explore how enterprise data captures the *DNA of an organisation*âthe what, where, when, who, how, and ultimately the why behind decisions. He will explain why siloed data limits AI-driven decision-making, and how knowledge graphs provide a unified semantic layer that enables trustworthy, AI-powered control towers across the value chain.
**Aniket Mitra** â Aniket Mitra is the founder of Computationele Wetenschapsgroep (CW) which is a technology development SME that specialises in designing, building & scaling
Knowledge Graphs for enterprise customers across industry verticals like retail, manufacturing & logistics.
**17:30 - Talk 2**
**Building Trustworthy AI in Regulated Sectors â Moonjelly, Knowledge Graphs, and the Context Layer**
Surajeet Bhuinya will share how a dedicated context layer helps AI systems understand how organisations actually work. Using Moonjelly as a practical example, he will show how connecting people, documents, and processes into a living enterprise graph creates context unique to each industry and use caseâleading to better decisions, clearer accountability, and real business impact.
**Surajeet Bhuinya** â Surajeet Bhuinya is the founder of DataPebbles, a leading Data & AI company in the Netherlands. With 25+ years of IT experience, he operates at the intersection of data, AI, and innovation, building scalable, practical AI systems that deliver measurable business impact.
He is also the founder of Moonjelly, a platform that connects people, documents, and processes into a living enterprise graph, enabling teams to understand context, see impact, and act with confidence.
**18:00 - Talk 3**
**ReviewGraph â Using Knowledge Graphs to Predict Customer Satisfaction and Extract Hidden Insights**
Lifeng Han will present ReviewGraph, a graph-based framework that transforms customer reviews into knowledge graphs to predict ratings and uncover hidden insights. He will compare this approach with traditional NLP methods and LLMs, highlighting how knowledge graphs offer strong performance with lower computational cost, greater interpretability, and promising integration with RAG systems.

Wellbeing Heroes: End Game Co-creation part 3: Prototyping & Playtesting
Thanks to everyone who contributed during our previous two co-creation sessions on the **"Wellbeing Heroes: End Game"** project. We've established a clear vision, identified core themes (Polycrisis, healing, scarcity, gift economy), and defined our target audience as **17-65 old**.
We are now ready to move into the exciting **Prototyping & Playtesting** stage in our third session!
**You do not need to have attended the previous events! Feel free to check previous events for more information about the game background!**
The goal of this in-person session is to **try out and help shape the two primary game concepts** we've been developing:
* **Concept 1: Multiple Spaceships**
* A strategic board game where each player captains a spaceship/group with unequal resources and abilities, requiring difficult collaboration to survive an intensifying crisis. (Prototype led by Daan Heemskerk)
* **Concept 2: Single-Ship Roleplay Crew**
* A collaborative table top role-playing experience where players take on different roles within a single ship's crew (e.g., captain, food producer), focusing on internal power dynamics, resource administration, and moral reflection. (Prototype led by Mahdi Abdelwahab)
We need your hands-on participation to test the mechanics and help us refine the design before the final version.
**Key Session Details:**
* **Activity:** Eating together and Testing two game prototypes.
* **Target Group:** 17+
* **Group Size:** Ideal for 5â7 per prototype.
* **Duration:** Estimated 4 hours, including drinks and eating.
* **When:** 30th of January 2026, at 18h.
* **Location:** Utrecht, Rosa Buurtcentrum, Lombok
We look forward to prototyping and shaping the **"Wellbeing Heroes: End Game"** with you!

ArnhemJUG - January meetup
**ArnhemJUG**
We are excited to announce the first meetup of 2026. We are welcomed by OpenValue Arnhem for the January meetup!
**Agenda**
* 17:00 CET walk-in
* 17:30 â 18:30 Food and drinks
* 18:30 â 19:30 talk: **Bigger Unit Tests are Better - why small unit test classes will slow you down** by **Peter Schuler**
* 19:30 â 19:45 break
* 19:45 â 20:45 talk: **Creating effective and objective architectural decision records** by **Piet van Dongen**
* 20:45 â 21:30 drinks
**Bigger Unit Tests are Better - why small unit test classes will slow you down**
Do you take care that every class in your system has a separate unit test class? Are you a proud Test-First advocate? A code coverage evangelist? Are you the Sonar police in your team? Do you take pride in knowing all the quirks of your mocking framework? Then this session might be a cold shower for you.
You will see how the general approach to unit testing might harm your flexibility. But a few simple changes in your approach will make your life better, your coding faster, your refactoring easier and your understanding of the business requirements stronger.
In this presentation, you will learn new strategies that will help you make your unit tests bigger. First, guided by clear code examples, we will look at why having many small test classes may harm you. Secondly, you will understand why making the tests bigger is such an important improvement. And lastly, you will learn techniques and tricks that will help make your unit tests bigger.
**About Peter Schuler**
Peter is a lifelong Java developer with a passion for TDD and code quality. Lately he has become a Java community lead for the Rabobank as a side hustle. In his off time, he likes to work in the garden or goes for a short run.
**Creating effective and objective architectural decision records**
Documenting decisions is like eating your veggies as a kid: they keep telling you itâs good for you, but you just hate doing it. Architectural Decision Records (ADRs) to the rescue! ADRs are perfect for just-in-time, just-enough documentation for engineering teams and organizations.
During this session, you will learn how to make architectural decisions effectively and objectively by:
* Learning the structure of a good ADR (no more walls of text that nobody reads anyway!)
* Practicing how to turn subjective choices into objective ones (no more pros and cons lists and tribal conflicts!)
* Creating editable diagrams, fast (no more spending hours wrestling tools that your collaborators donât know how to use!)
* Collaborating quickly with technical and non-technical stakeholders (no more hours of Tower of Babel meetings!)
* Reporting the decision using effective language and fit-for-audience diagrams (no more writing reports that end up unread in drawers!)
Do you want to learn how to facilitate good decision making without spending weeks looking for consent?
Then join this session and you will walk away a better software architecture decision facilitator.

Azure CBUS February: Build Your Own MCP Server
### Tools in your AI's Toolbox : An introduction to MCP Servers
The generative AI revolution has unlocked unprecedented capabilities, but the next frontier is agency: empowering models to interact with, query, and act upon the world. The current challenge is the âN x M integration problem,â where every AI model requires a custom, brittle integration for each external tool or data source. This approach simply doesnât scale. How can we give an AI access to our sales leads, code repositories, or IoT devices in a standardized, secure, and reusable way?
This session introduces Anthropicâs Model Context Protocol (MCP), the open-source framework designed to solve this challenge and become the universal connectorâthe USB-C portâfor AI. MCP standardizes how AI models discover and use external tools, moving beyond simple function-calling to a robust, client-server architecture. We will dive into how this open protocol is creating a new ecosystem for building powerful, context-aware AI agents.
Join this session for a developer-focused introduction where you will learn how to:
Understand the core concepts of the open-source Model Context Protocol and its architecture.
Utilize pre-built, open-source MCP servers to instantly connect AI to tools like Git, Slack, and databases.

DevOps Columbus January: Learn Infrastructure-as-Code Through Minecraft
## Details
\#\# Learn Infrastructure\-as\-Code \(the FUN Way\) â Through Minecraft đŽâď¸
**Joint Meetup: DevOps Columbus - Azure CBUS - Columbus HashiCorp User Group**
What if learning Terraform and Infrastructure-as-Code didnât feel like a whitepaper⌠but more like a game?
Join us for a joint DevOps Columbus, Azure CBUS and Columbus HashiCorp User Group meetup where **Mark Tinderholt** \(Principal Architect\, Microsoft Azure \| HashiCorp Ambassador \| âThe Azure Terraformerâ\) shows how **Minecraft** can be used as a surprisingly powerful way to understand real-world Infrastructure-as-Code concepts.
In this session, Mark will demonstrate how Terraform and Azure can be used to provision, configure, and manage Minecraft serversâwhile teaching the same patterns youâd use for production cloud infrastructure.
\#\#\# What weâll cover
* Infrastructure-as-Code fundamentals using **Terraform**
* Provisioning real infrastructure on **Azure**
* Applying **IaC best practices** (immutability, repeatability, versioning)
* How playful environments like Minecraft make complex concepts *click*
* Why learning through experimentation beats click-ops every time
\#\#\# Who should attend
* Developers, platform engineers, and cloud engineers
* Terraform users (new or experienced)
* Anyone curious about Infrastructure-as-Code but tired of boring examples
* Minecraft fans who want to see it used in a totally unexpected way
No prior Minecraft experience requiredâjust curiosity and a willingness to learn infrastructure the fun way.
Come for the blocks, stay for the Terraform. đ§ąâĄď¸đ

CBusData - Ok I Want to Get Data into Fabric - Now What?
I love my job and one of the main things I do is help customers get going with any of the data technologies at Microsoft. Right now there are a lot of my customers asking about Microsoft Fabric. It's hard to weave across all the shiny new options across the Fabric landscape, let alone figure out where it fits into your organization. In this session we'll focus on answering one question - how can I get data into Fabric? We'll talk through the "it depends" options and see some of the options in live demos.
