LCU 1st Summer BBQ of 2026!
Hi all! 🙂
It's BBQ time again! With a warm 36°C we figured we'd return to our regular spot in Wilhelminapark for the first language cafe BBQ of the season!
We'll provide a BBQ or two, so please bring your own food to put on there, drinks, blankets, cutlery, maybe another BBQ, and anything else that you might need!
See you there, in Wilhelminapark at 19:00!
[https://maps.app.goo.gl/jheBHQ8QDvW4pYFk9](https://maps.app.goo.gl/jheBHQ8QDvW4pYFk9)
In case you are not in our language cafe database yet, please use this form: [http://goo.gl/forms/oSCn9Dn8m8](http://goo.gl/forms/oSCn9Dn8m8)
If you're joining us for the first time, just drop by to the Wilhelminapark this time and have fun! Note that our usual Wednesdays are in the Café Marktzicht. We will not organize any language groups in the park, but most people will speak English and Dutch.

**Win a 1-month Claude Code MAX subscription (worth €100)**
20:00 – 21:00 Networking Drinks
About the talks:
**Let's use Spring Boot to build games, because why not?**
**Alexander Chatzizacharias - JDriven**
If you work on enterprise grade microservices on the JVM, you have undoubtedly heard of Spring Boot. Most developers see it as the reliable backbone of enterprise software. It is stable, predictable, and safe. But what if we took all those conventions and threw them out the window? What if we repurposed the IoC container, event listeners, and bean lifecycles to reveal what Spring Boot was always meant to be? A game development framework!
Join Alexander as he attempts to deconstruct and demystify the Spring ecosystem by forcing it to do things it was definitely not designed for. We are not talking about simple text adventures here. We are talking about building complex, real-time games like a Terraria clone or a souls-like RPG, all powered by the same annotations you use for your day job.
This session explores what happens when you learn technologies by breaking them. Whether you are a Spring veteran or a newcomer, this talk offers a fresh perspective on the tools you use every day. You will leave with a better understanding of how Spring Boot works under the hood and the inspiration to build something completely unnecessary, just because you can. Come for the absurdity, stay for the laughs, and see what happens when you strip away conventions and best practices in the pursuit of a wild idea.
**Zero Trust: Applying Military Procedures to Cybersecurity Challenges**
**Laurens Blankers - JDriven**
Cybersecurity is becoming more and more challenging. A lot of ‘new’ solutions are being proposed, including Zero Trust. Although, if you really drill down to the core, Zero Trust proposes a way of working which has been standard in military organisations around the world for over 80 years. Join me in breaking down Zero Trust into a number of easily understood principles including a number of approaches which can be applied to your software today.
Laurens is a Java Software Engineer with over 20 years of experience. He excels at extracting the bigger picture and applying this to the smallest details. He combines this theoretical knowledge with his vast practical experience and hands-on mentality. Laurens has significant experience with a number of Java based platforms, including Jakarta EE and Spring (Boot). Ranging from REST microservices in the cloud to applications for controlling custom hardware on the desktop. In his personal life Laurens enjoys Science Fiction, board games, and history of technology.
**Practical AI Developer Setup Demo**
**Alexander Chatzizacharias - JDriven**
After the talks, Alexander will give a live demonstration of his AI-powered development setup and workflow. Discover how modern AI tools can help you write code faster, improve productivity, automate repetitive tasks, and accelerate learning. You'll get a practical look at the tools, techniques, and workflows that developers are using today to get the most out of AI.
At the end of the demo, we'll hold a giveaway where one attendee will **win a** **1-month Claude Code MAX subscription (worth €100)**.
Speltestavond #84
*(🇬🇧 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)! Spellenmaakgilde Nijmegen maakt onderdeel van het [Nederlandse Spellenmaakgilde](https://spellenmaakgilde.nl/) en is onderdeel van het SAZ. Je vindt ons daarnaast ook in het #Nijmegen kanaal op de [Discord-server van het Spellenmaakgilde](https://discord.gg/6JzD6Sz2m5).
🇬🇧 **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. 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))!

Wat doe je met je opvoeding? - Utrecht
**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:**

Feed an AI-agentic beast with proper data
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

ArnhemJUG - June meetup
**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.

The Ronald McDonald House (RMH) provides housing and meals for families with sick children. The Columbus RMH is the largest in the world with 137 rooms. COUNT has been volunteering there since May 2014.
Housewarmers work with RMH guests to provide a home-like environment - greet, assist with family needs, answer phones, give tours, assist with checkin/checkout, prepare guest rooms after checkout, clean facility, laundry, restock supplies and staff the front desk. RMH Housewarmers volunteer at least one four-hour shift a month. All Housewarmers must complete an application and agree to a background check before they can be full fledged volunteers.
Volunteer Opportunity
Open Shelter has teamed up again with Red White and Boom! Friday, July 3rd & we are looking for volunteers to run the event’s alcohol booths. Proceeds from sales go to the Open Shelter’s organization.
There are two available shifts: 12-6p & 5-11p.
There will be an ipad-like device to process transactions in addition to cash. Everything will be in bottles or cans, so transactions should be very easy. Must be 21+.
There are multiple beverage stations along the Civic Center Bridge. The stations are covered and also have beverage trucks next to them, so volunteers can cool off in the trucks.
As far as parking, it is suggested those who are coming from the east use the Columbus Commons Garage, and those from the west use the Belle Street Garage.
Harry from the Open Shelter will be your contact.

Soulbits Circle: A Monthly Gathering
**Soulbits Circle: A Monthly Gathering**
**Every fragment of your story is medicine; come weave it into being**
**Hosted by: Caitlynn Fortson**
**[www.kalikwellnesswithin.org](www.kalikwellnesswithin.org) \| [www.centerfornewlife.org](www.centerfornewlife.org)**
**The Center for New Life or Virtual, upon request**
**Monthly Circles \| Fridays 6:30\-7:30PM**
**Upcoming Dates: 5/1, 5/29, 6/26, 7/24, 8/28, 9/25, 10/23, 11/27, 12/18**
A monthly healing space where we gather to tend the pieces of ourselves and weave them back into wholeness that we are. Each session opens with a Soulbits oracle image setting the tone for the gathering we will move through. We will come together to honor the natural rhythms of rooting, rising, releasing, and receiving; the cycles that shape the soul’s journey.
Through the four pillars of being: mindset, movement, connection & nourishment, we will create a space where imagery, sensation, and community weave together. Where the body becomes the guide, images act as mirrors, and the soul speaks. This circle is about noticing what rises, honoring what’s true, and reconnecting with the parts of yourself ready to be seen.
This is a space to gather your scattered pieces, soften your body, and return to your truth with community by your side. Soulbits Circle is a reminder that every fragment of your story, every soulbit, belongs. Together we weave them into the blooming wholeness that you are.
