**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!

Are you an **expat** in **Utrecht** and do you want to **learn how to swim?** Look no further! Dive into **personalized swimming lessons** with **Your Personal Swim Coach**.

'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.

Van de betrouwbare basis van SUSE Linux Enterprise Server (SLES) tot multicluster Kubernetes-beheer met Rancher en zero-trust containerbeveiliging met SUSE Security: SUSE biedt een compleet, onafhankelijk open-source ecosysteem van besturingssysteem tot cloudtechnologieën.

Daarbij prikken we door de marketingverhalen heen en delen we praktijkvoorbeelden van organisaties die het volledige SUSE-portfolio inzetten om complexe infrastructuuruitdagingen op te lossen. Ook laten we zien hoe klanten de overstap maken van een Amerikaans georiënteerde infrastructuur naar een Europees alternatief. Tot slot geven we een live Rancher-demo, waarin je ziet hoe alle componenten naadloos samenwerken om moderne IT-landschappen te beveiligen, beheren en schaalbaar te maken. Wat kun je verwachten: * **Het volledige SUSE-verhaal** Hoe een Europese open-source pionier een complete technologiestack heeft opgebouwd – van operating system tot Kubernetes. * **Meer dan alleen containers** Inzicht in het bredere portfolio (Linux & Cloud Native) en waarom dit aansluit bij de behoeften van moderne enterprises. Inclusief mogelijkheden om jezelf hierin te laten opleiden tot specialist. * **Praktijkvoorbeelden uit de markt** Hoe organisaties het volledige ecosysteem gebruiken voor stabiliteit, compliance en schaalbaarheid en waarom SUSE steeds vaker de nieuwe standaard wordt. * **Live demo** Zie het portfolio in actie en ontdek hoe SUSE de volledige keten verbindt: van infrastructuur tot en met de applicatielaag.
