Open Jams

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.

**Locatie:** Huis van Actief Burgerschap, Neude 11, 3512 AE, Utrecht **Datum:** 25 juni 2026 **Tijd:** 19:15 inloop, start 19:30 en eindigt om 21:30 Op weg naar volwassenheid neem je (on)bewust allerlei dingen mee vanuit het thuisfront. Je ouder(s) en/of verzorger(s) bepalen een lange tijd de regels van je leven. Ze planten zaadjes die uitgroeien tot denkbeelden, normen en waarden. Hoe kijk je naar wat je van huis uit hebt meegekregen? Hoe heeft je opvoeding je gevormd? Welke verwachtingen hebben jouw ouder(s) en/of verzorger(s) jou meegegeven in dit opzicht? Tijdens deze avond maak je de balans op. Tradities binnen het opgroeien staan volgens socioloog Marlies Buchman lang niet meer zo vast als vroeger. Eerst ging je naar school, werken, trouwen en samenwonen, nu is dat veel flexibeler. **Wat kan je verwachten?** Een avond in een ontspannen sfeer, speciaal voor 18-35 jaar. Geniet van een drankje van ons en ontmoet nieuwe mensen. Je kunt alleen komen of samen met een vriend(in). Liever een buddy? Geef het aan bij je aanmelding. Tijdens de avond maak je makkelijk contact met anderen die ook op zoek zijn naar betekenis. Meld je aan en kom bloeien! **Aanmelden kan via de onderstaande link:** https://www.dekwekerij.org/bloeiklas/opvoeding/

Are you ready to blast past the limitations of a jam session? Are you ready to extract every drop of musical creativity? This workshop is for those who are ready to risk putting everything that goes in their brains out there in musical form! After this workshop, you're never going to look at music the same way! More than a jam, the Jam With Humans workshop is a workshop on how to jam. Your teacher Daniel Matias Ferrer will guide you through exercises on musical improvisation and creativity. In a typical workshop, we start by getting to know each other and why we came to the workshop. Then, we warm-up by allowing ourselves to be silly and childishly curious, usually via theatrical exercises. At this point, we replace the verbal component of these exercises by improvised music. We proceed with exercising our skills in coming up with musical ideas, transferring them and listening to the ideas of others, and finish the session with one big jam. **The Jam With Humans Workshops are free to join. A (voluntary) contribution will be requested at the end of the session for helping with production costs (suggested €20).** **🤔FAQ🤔** **Should I bring an instrument?** If you can, please bring your instrument. The Q-Factory studio will be equipped with a bass and two guitar amplifiers, a drum set (no cymbals) and a PA system with many vocal microphones. It's also possible to rent cymbals, congas, a digital piano, guitars and basses from Q-Factory for very reasonable fees. **I’m a beginner, can I join?** Yes! The workshop is for everyone: we’ll be able to use whatever sounds you can produce plus all your knowledge of music (both from listening and playing) to explore how they can be used creatively in an improvisational setting. The workshop is also a safe space, so don’t be shy in taking risks musically, we have your back! **I’m a professional, should I join?** Absolutely! Given that the workshop is about improvisation and creativity, chances are you’ll be faced with exercises that allow you to explore your instrument in ways you never thought about before. Plus, you’ll be practicing mechanisms of being able to improvise with anyone else, in different instruments and with different musical sensibilities. **How often should I participate?** As often as you want! The workshops are weekly (or fortnightly during summer time) and their syllabus is circular. All workshops are different and it’s recommended that you come to at least three before you make up your mind about them. Otherwise, show up as often as you want: every week, every two weeks, many workshops in a row and then none for a few months… There is only one catch: those who come often will be invited eventually to join The Jam With Humans Orchestra in a separate rehearsal and join our Jam With Humans live shows. Also, those who come really often (regularly for over a year), will be invited to teach workshops themselves, as that’s a fundamental part of the Jam With Humans pedagogical ethos. **Does everyone have to participate, or can I just watch?** Everyone has to participate! If you’re in the room, you’ll have to participate. No observers! Again: we get your back, no worries. Hold our hand and be ready to dive into the world of improvised music, we’ll be there to help you through the journey. **What style do we play?** Whatever you’d like to play. Musical styles, musical genres, those are words which tend to not be imposed to the workshop participants. The goal of the workshop is to harness whatever is your musical language and sensibility to better cooperate with others in an improvisational context. **Is there anything I should do to prepare?** Actively listen to a lot of music. Sit down and think of what went through the musicians/composers heads that lead to what you are listening to. If you’re looking for inspiration, start with one of the three big influences on the Jam With Humans musical improvisation style: John Zorn, Sun Ra, Frank Zappa.

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!

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.

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**

The sunny and warm summer weather finally seems here to stay, which makes it the perfect time to craft outside in the park!☀️ Join us for a relaxed crafting evening picnic in the park, where we bring our projects, spread out our blankets, and create together in the open air. Whatever you're working on, whether it's knitting, scrapbooking, sketching, embroidery, or that half-finished project that's been waiting for some attention, bring it along and enjoy an evening of making things in good company. You can join us at whichever time works for you. Don't feel pressured to join from the start at 19:00. You're still just as welcome to arrive at 21:00. This get together is also a great chance to chat, share tips, and get inspired by what everyone else is making! * 🎨 **What to bring?** Your own creative supplies and projects, whatever you love to work on. * 🧺 **Picnic style** Bring a blanket to sit on, and feel free to also bring some snacks and drinks. * 🔄 **Want to swap?** Got craft supplies you no longer need? Bring them along, there will be some space to swap items. 📍 Wilhelminapark

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

Dodgeball is back again! If you’ve been wanting to come out, this is an easy one to join. We’ll be playing for about 1.5 to 2 hours, you do not need to bring any equipment, and no experience is needed. We use a specific set of rules and equipment to make the games run better and keep them fun for everybody, not just people who already know how to play. If it rains, the event will be canceled.

**What is a send-off?** Before we head to St. Louis for the Barbershop Harmony Society International Convention, The Alliance opens its doors to the community for a **free** preview of our competition set. This gives us the opportunity to perform in front of an audience before we take the international stage. We would love to see you there!

We'll meet at The Capital One Café, 167 Easton Town Center, Space A-103. This is in the main mall where the Microsoft store used to be, on your left if you're standing at the bottom of the AMC Theater escalator. Join us on Saturday for an hour of uninterrupted wordmaking! • What we'll do Join us for an hour of writing! We’ve discovered that it’s strikingly helpful to write with other writers. See if it’s true for you at 10AM on Saturday mornings. Be it a book, blog, script, essay, dissertation, resume, melody, poem or just plain work stuff, you are invited to write it with us. No one will see what you've written or give you unsolicited advice. Instead of just thinking about writing, come and get some real writing done. SCHEDULE: 10:00 - SESSION 1: quick intros. 10:10 - timer starts: write for 1 hour. 11:10 - chat / take off / keep writing. OPTIONAL SOCIALIZING happens at 11A-11:30ish. Writing is very solitary. Connecting (and sometimes even commiserating) with other writers is a cool thing. BEING LATE IS OKAY: just show up and get settled, then check-in with me after the session. (I’ll be the person with the Shut Up & Write! sign.) If you were on time, please be willing to make room for the friendly latecomer. Happy writing and I look forward to seeing you! • What to bring Whatever you need to be able to write! Bring earbuds/earplugs if you want to block noise or the occasional conversation by other patrons. Electrical outlets are limited, so charge your devices before whenever possible. See you at The Café on Saturday!
