Site Reliability Engineering (SRE)

**ArnhemJUG** We are excited to announce that we are welcomed by TenneT for the June meetup. Please note that TenneT **requires** all visitors to present a **valid ID** upon entry and that we must provide a list of attendees in advance. For this reason, **we need your full name** as it appears on your ID. If your Meetup username is different from your real name, we'll get in touch before the event to confirm the name on your ID. Also note that we start 10 minutes earlier than normal, the first talk will start at 18:20 **Agenda** * 17:00 CET walk-in * 17:30 – 18:20 Food and drinks * 18:20 – 19:10 talk: **How we develop and maintain our (12 year old) DDD app** by **Dan Haywood** * 19:10 – 19:30 break * 19:30 – 20:20 talk: **AI augmented teams: from tab complete to AI workforce** by **Radek Kowalski** * 20:20– 20:45 drinks **How we develop and maintain our (12 year old) DDD app** We’re a small team (about 2.5 FTEs) but we develop and maintain a big app - it processes €500m invoices in turnover each year, for a €4bn company that owns and operates shopping centres throughout Europe. And it’s a DDD app too … it’s our focus on the domain that allows us to do a lot with, well, not much. In this talk we’ll try to explain our way of doing things, some of which might be obvious and you’ll know, some of which could be a bit more contentious or surprising. The technology may intrigue you, but the mindset is just as important. **About Dan Haywood** Dan Haywood is an independent consultant based in the UK, an ASF member and committer to Apache Causeway. He spends his days either cutting code or advising governments. **AI augmented teams: from tab complete to AI workforce** Ten months ago, when Radek and his team launched their project under a tight deadline and limited budget, it seemed nearly impossible. Fortunately, it was 2025—and agentic coding tools were ready to help. The team embraced these tools as a lifeline, developing a workflow where engineers and AI agents built software side by side. The result: delivery ahead of schedule and within budget. In this talk, Radek shares how the team’s approach evolved, the practical strategies they developed, and the lessons they learned to overcome constraints in time and cost. **About Radek Kowalski** Over a 20+ year career in IT, Radek has grown from software engineer to architect to senior leader—before returning to the trenches to embrace the AI revolution and shape it firsthand. In the past year, he has helped organizations and engineering teams embed AI into both their business and daily workflows.

In this hands-on workshop we’ll work through four real-world scenarios in Python: finding the minimum viable context for sales questions, keeping frequency signals intact when summarizing support tickets at scale, selecting the right columns for churn analysis on a wide customer table, and extracting structured fields from messy product listings with validation you can trust. You’ll write and discuss code together — practical patterns you can take straight back to work. **Agenda** \- 18:00 Doors Open \- 18:30 Start of the Workshop \- 20:00 Workshop Closing & Announcements \- 20:10 Networking \- 21:00 Event Closing **GitHub Repo** [https://github.com/pyladiesams/feed-AI-agentic-beast-proper-data-jun2026](https://github.com/pyladiesams/feed-AI-agentic-beast-proper-data-jun2026) **Stream** [YouTube Stream](https://www.youtube.com/live/2EnszJLzzAc) **Speaker** [Jessica Eggen](https://www.linkedin.com/in/jessica-eggen-579b50155/) Jessica Eggen is a Data Analytics Engineer who loves to spent her time wrangling and puzzling with real-world data at scale.

Ongeveer eens per maand is er een Bitcoin Meetup in Arnhem. Dit keer met een presentatie en Q&A van Hester Bais. Zie ook de promo video: [https://www.arnhembitcoinstad.nl/media/2026-06-26-MeetupHesterBais/PromoMeetupHesterBais.mp4](https://www.arnhembitcoinstad.nl/media/2026-06-26-MeetupHesterBais/PromoMeetupHesterBais.mp4) Sinds 2014 dringt de Nederlandse advocaat en klokkenluider Hester Bais er bij de autoriteiten op aan om een grootschalige internationale bankfraude in OTC-derivaten en constructies met onderpand en lege entiteiten stop te zetten. Door hun handelswijze raakten banken in Nederland voor ongeveer €200 miljard, in Duitsland voor €400 miljard, in Frankrijk voor €320 miljard, en in het Verenigd Koninkrijk voor €300 miljard onder water met betrekking tot het onderpand—en mondiaal gaat het om biljoenen euro’s. Samen met Wink Sabée schreef Hester het boek Worst Bank Scenario, waarin in detail wordt beschreven hoe “Bretton Woods 2.0” wordt uitgerold.

Join us for a cozy, distraction-free afternoon where we slow down, connect, and create. This is a phone-free event — a chance to step away from screens and be fully present. We’ll start by getting to know each other in a relaxed setting, and then everyone will spend time working on their own creative project. Think simple, mindful, and low-space activities like: • Sketching or drawing • Painting (small canvases only) • Journaling or writing • Knitting or crochet • Any quiet, offline creative hobby 💡 Please bring something that doesn’t take up too much space and doesn’t require digital tools. We’ll sit together, enjoy the calm atmosphere, and gently connect — no pressure, just shared creativity. ⚠️ Limited spots available: maximum of 10 participants Sign up quickly to secure your place!

**Hilversum Code & Coffee** A friendly meetup for developers, tech enthusiasts, students, freelancers, founders, and anyone interested in coding.

Welcome to **Jiada Mahjong**, a place to learn, play, and connect around the table. Whether you’re completely new or already know the game, you’re welcome. Beginners are guided step by step, while experienced players can jump straight in and play at their own pace. On **Friday, 1 May**, we are hosting **A Mahjong Night** at **Grand Café LIVING in Utrecht**. Expect a relaxed, beginner-friendly afternoon of Mahjong, where you’ll learn the game, play together, and meet new people in a laid-back atmosphere. ✨ **What to expect:** - Step-by-step Mahjong introduction - 3 hours of casual play with guidance - Two drinks (wine, beer, or soda) - Two bits (bittergarnituur) - Extra drinks & bites available for purchase at the bar - Relaxed social atmosphere - Meet new people and share a table **All Levels Welcome** Whether you’re completely new or already play comfortably, this session is designed so everyone gets the right experience at the right table. **Beginner Workshop (never played)** Learn how to play Sichuan Mahjong (also known as “Bloody Battle to the End”), a fast-paced and accessible variant that blends strategy, skill, and a bit of luck. This beginner workshop is designed to get you from zero to playing in a single session. You won’t sit through a long lecture. After a short introduction, you’ll start playing right away. A dedicated host will guide you step by step at the table—explaining the tiles, the flow of the game, and the core techniques as you go. You learn by doing, not by memorizing. By the end of the session, you’ll be able to play a simple version of Sichuan Mahjong independently. Depending on how quickly you pick it up, you may also start understanding how scoring (points) works. Why Sichuan Mahjong? It’s one of the most popular and beginner-friendly Mahjong styles. The rules are more accessible than many other variants, while still offering enough depth to keep the game interesting as you improve. **Open Play (Basic, Intermediate & Advanced)** Already familiar with Mahjong? You’ll be seated with players at a similar level and can jump straight into gameplay. Questions are always welcome, but the focus is on smooth, uninterrupted play. We support multiple Mahjong styles, including Sichuan, Hong Kong, and Riichi. Tables are organized based on player preferences whenever possible. If enough players wish to play the same style, we’ll group them together. However, this depends on attendance and cannot be guaranteed. If there aren’t enough players for your preferred style, you may be seated at another table, and we’ll provide a brief introduction to help you get started. 📅 Firday, 26 June 🕒 18:00 – 21:00 🏷️ Tickets can be found on our website: [JiadaMahjong.com](https://jiadamahjong.com/products/a-mahjong-night-grand-cafe-living) 📍 **Grand Café LIVING**, Weg tot de Wetenschap 400, 3584 CN **Utrecht**

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD
