Dyslexie Cafe Utrecht is er voor alle conceptuele denkers. Voor mensen met dyslexie, hun naasten
 en voor iedereen met een brein dat net even anders werkt. Een plek voor ontmoeting en herkenning. Hier hoef je niet uit te leggen
waarom je hoofd sneller denkt dan je hand kan schrijven.
Of waarom je ideeën grenzeloos zijn
maar niet altijd uitkomen zoals je zou willen. Hier mag je binnenlopen bij mensen die weten hoe het voelt. en schaamteloos jezelf zijn. Tijdens het cafe creëren we ruimte, praten we over de krachten en de uitdagingen. Niet hangen en luisteren maar interactief ontdekken. Soms met een thema.
 Soms ontstaat het gesprek vanzelf.
 De inhoud wordt mede bepaald door jou. Kom en deel je verhaal, stel vragen en ontdek nieuwe inzichten met mensen zoals jij.

On Tuesday, we’ll get together with climbers of all different levels to boulder and socialize at Monk. We’ll arrive from 19.30h onward to introduce ourselves or catch up. At 20.00h, we’ll climb together as a group. If a lot of people join, we might split into two groups. Then around 21.00h, we will wrap up and go for drinks at the bar or on the terrace. All you need to bring are sporty clothes and a water bottle. Keep in mind that you need to pay the entrance fee to the bouldering hall. If you have never bouldered before, you might want to join our beginner group first!

Boardgame night #176 The idea is: play a game, have a drink and chat with friendly people. We start around 20.00 with playing board games so that's the perfect time to jump in and play with us. We will bring a couple board games, but you're also welcome to bring your own games. Feel free to join, bring friends or family. We hope to play with you then! You can also signup on facebook. Visit us at: [https://m.facebook.com/groups/463859440486833](https://m.facebook.com/groups/463859440486833)

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

Welcome, readers! Our June read is ***Endurance: Shackleton's Incredible*** ***Voyage*** **by Alfred Lansing.** A work of nonfiction, and one of the most astonishing survival stories in history, we follow Sir Ernest Shackleton and his crew after their ship is crushed by Antarctic ice. Stranded in one of the harshest environments on Earth, the men endure months of isolation, freezing temperatures, and near starvation—yet refuse to give up hope. Lansing brings their ordeal to life through vivid detail and firsthand accounts, capturing both the brutality of nature and the resilience of the human spirit. At its core, the story is a powerful testament to leadership, perseverance, and the unbreakable will to survive against impossible odds. Looking forward to discussing with everyone! We will meet at Zaftig Brewing Co in their event room in the back. We are welcome to bring in our own food, but **all** **drinks must be purchased at the bar.** Happy reading! 📖

Early-bird coffee and conversation at [Grandview Grind](https://www.facebook.com/profile.php?id=100063534163841)!
