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.

A great ride along the Vecht and Gein rivers. You will love this route. Please ride single file along the winding river as there can be cars around each corner. **Route:** https://connect.garmin.com/modern/course/441606271 GPX: https://drive.google.com/file/d/17-T_pT_GH3QKSFcH1WWgfArvxSdAkVzO/view?usp=sharing **Afterwards:** Drinks at Polder https://maps.app.goo.gl/tbt5DDG7YLU3uWvaA **Rules:** \- Download the route to your cycling computer so you can always find your way home \- Make sure to arrive on time \- Before you ride\, decide as a group how you want to ride: you can split up in a fast and a slow group or stay together\, but make sure to discuss what pace you are going to ride and whether you are going to wait if someone is slower than the group\, or not\.

Samen sporten, gewoon voor de fun, elke week een divers programma, met allerlei verschillende sporten. Je hoeft niet de beste te zijn, maar wel zin hebben om samen te spelen en te leren. Tijdens een training doen we verschillende spelletjes, basketbal, voetbal. volleybal, spikebal, honkbal. Kom je ook, de bal ligt bij jou!! Eerste keer meedoen is altijd gratis, daarna kan je beslissen of dit voor jou is, of niet!! Dus kom een keer proberen. Kan je niet op deze dag, we sporten ook op andere dagen nl Zondag om 9:30 of Maandag om 20:30 Stuur mij een berichtje als je op die dagen een keer wil proberen! The amount of people rsvp'd to this game doesn't match the real number of people at the event, as Meetup is only used for promotion purposes.

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.

**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.

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.

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
