**When:** Wednesday\, July 1st \| 🕒 Doors open at 19:00\, battle starts at 20:00 **Where:** De Ping Pong Club, Utrecht **Damage:** €4,07 (Buy your tickets in advance as spaces are limited! Secure your spot directly with the venue [here](https://shop.weeztix.com/37dc63d6-519c-11f0-a9cb-7e126431635e/events?shop_code=5rn36dck)!) **The Vibe:** I checked out De Ping Pong Club last week—it is an awesome location! They even have board games if you need a break from the action. I played there recently outside of a tournament, and let me tell you about the "athletic" standard: if you can hold two beers at the same time, you are officially qualified. This is not the Olympics, this is [around the table](https://depingpongclub.nl/agenda/). Leave your sports watch at home; this is a purely social event where your actual speaking time will easily outlast your playtime. **Pro Tip:** There are bonus points for costumes and alternative, non-paddle equipment. Fry-pans, textbooks, or flip-flops? Bring it. **Essential Training Routine:** If you actually want to take this seriously and lift the trophy, you *must* complete this strict two-step preparation: 1. Watch the [Balls of Fury Trailer](https://www.youtube.com/watch?v=HXR_NLDMUk8&t) to master the illegal underground table tennis mindset. 2. Blast [Armin van Buuren's Ping Pong](https://www.youtube.com/watch?v=Z8V5GfFeUDs) on repeat to get your hand-eye coordination synced to 138 BPM. **P.S.** Who is willing to play in my team **"ExBats"**? (Yes, a terrible pun merging "Expats" with *bat*, the Dutch word for racket). Drop a comment below if you're in!

The Rabobank Tech Community together with [CodeLab](https://www.meetup.com/codelabjug/) is organizing a Java meetup for our community. Victor Rentea will speak at Rabobank in the evening of July 2nd. Because of the limited number of seats, please keep your RSVP up-to-date, so we can welcome someone else if you can't make it. **IMPORTANT:** Due to Rabobank security measures, we need to present in advance an attendee list with everyone’s full names. This is partly because Rabobank is, well, a bank, but also related to safety measures in case of an emergency. That is why we need to ask you the following: If you do not use your real full name as profile name at Meetup.com, could you send us your full name in a private message? The attendee list presented to Rabobank will only be used for visitor's registration at the reception and will not be published anywhere, we only do this to comply with said safety measures. The meet-up will be held in a non-public area of the building. This means that without proper registration the security team will not be able to let you in. Hoping for your understanding. === **Agenda** 17:00 Walk in + Dinner 18:15 Talk 20:00 Drinks 21:00 Ending **Talk** **Agentic Engineering - Patterns and Anti-Patterns** A compilation of emerging patterns and common pitfalls observed in over 50 companies. From unhealthy context management, naive prompting, unvetted AI slop, and careless supply-chain to self-learning skills, sub-agent orchestration, AI guardrails, and backpressure. Join this talk to cut through the hype, learn from the early adopters of agentic engineering – see what works, what ships better code 3x faster in production, and what fails **Speaker** Victor Rentea is a Java Champion and an Independent Trainer delivering intense webinars for dozens of companies worldwide since 2014. His passion is Simple Design, Refactoring, and Unit Testing, about which he regularly talks at top conferences, but also to the European Software Crafters Community that he founded.

'THE SYMPATHIZER' by Viet Thanh Nguyen 'The winner of the 2016 Pulitzer Prize for Fiction, as well as seven other awards, The Sympathizer is the breakthrough novel of the year. With the pace and suspense of a thriller and prose that has been compared to Graham Greene and Saul Bellow, The Sympathizer is a sweeping epic of love and betrayal. The narrator, a communist double agent, is a man of two minds, a half-French, half-Vietnamese army captain who arranges to come to America after the Fall of Saigon, and while building a new life with other Vietnamese refugees in Los Angeles is secretly reporting back to his communist superiors in Vietnam. The Sympathizer is a blistering exploration of identity and America, a gripping espionage novel, and a powerful story of love and friendship.' ***Please read the book and join us for a lively discussion (in English) about the contents during our afternoon book club meeting.*** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **PLEASE NOTE:** This is an IN-PERSON event in Amersfoort, The Netherlands.

Do you want more motivation and confidence to build Lasting Relationships? This is a free, in-person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Are you burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival, while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This class is held at the Dianetics and Scientology Life Improvement Center.
