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 The attendee list presented to Rabobank will only be used for visitor's registration at the reception and will not be published anywhere, we only do this to comply with said safety measures.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.

**SUSE X I-share:** **Sprekers:** * [Hugo de Vries](https://www.linkedin.com/in/hugo-de-vries/) (Solution Architect) * [Bert Boerland](https://www.linkedin.com/in/bertboerland/) (Account Executive) * [Keown de Koning](https://www.linkedin.com/in/keowndekoning/) (Head of Channel) **Beschrijving** ''Tijdens deze sessie nemen we je mee door het brede SUSE-portfolio. 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. We starten met de basis van SUSE en kijken terug naar de ontwikkeling van een Duitse open-source pionier in 1992 tot een wereldwijde enterprise speler van vandaag. 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. Of je nu infrastructure architect, platform engineer of security specialist bent: sluit aan en ontdek waarom het SUSE-portfolio perfect aansluit op jouw moderne infrastructuurstack!'' *Het programma zal deze avond als volgt zijn:* * Vanaf 17.15 u: inloop * Rond 17.30/18.00 u: eten * 18.30 u: start sessie * 20.00 u: afsluiting We zien jullie graag dan!

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 Factor-ij Amsterdam on Thursday 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: 11: 15 AM - Quick introductions 11: 30 AM - Timer starts: write for 1 hour 12: 30 PM - The End: chat, take off, or keep writing OPTIONAL SOCIALIZING happens at 12:30 pm after the writing is wrapped. 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 at Factor-ij! What Should I Bring? Whatever you need to be able to write! Bring earbuds/earplugs if you want to block the cafe’s overhead music or the occasional conversation by other patrons. Please come with your devices pre-charged, since we probably won't be always sitting somewhere with charging possibilities. Other Important Details: Travel by public transportation: 1. Take Tram 26 from the central station Amsterdam, and step out by the last stop. 2. Take bus 66 from the Amsterdam Bijlmer station, step out by Pieter Oosterhuisstraat, and further walk in the direction of the bus till the corner. FREE Wifi.

If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to.
