**IMPORTANT UPDATE:** Due to unexpected sick leaves within our speaker and organizing team, **we have to postpone this MeetUp to June 25th**. Everything else stays the same. **@everyone: Please review and update your RSVP status accordingly.** \-\-\- We'd like to invite you to our fourth installation for the Cloud Native Vienna MeetUps in 2026! Again we'll have two deep-dive talks and time to network and chat with friends in the Viennese cloud native community. A big thank you to **WKO Inhouse GmbH** for hosting us and providing food and drinks! **Agenda:** * **17:30:** Doors Open & Networking * **17:55:** Welcome from the Organizers * **18:00:** **Talk 1:** Rober Klonner (WKO Inhouse GmbH) **GitOps Visibility: Precise Argo CD diffs on every Pull Request** * **18:45:** Break & Refreshments * **19:00:** **Talk 2:** Thomas Hanser (Untis GmbH) **The Untis Platform Engineering Journey: GitOps Multi-Tenancy with Flux, GitLab, and Friends** * **19:45:** Open Networking We look forward to seeing you there! \-\-\- **Talks:** Rober Klonner (WKO Inhouse Gmbh) **GitOps Visibility: Precise Argo CD diffs on every Pull Request** Today's GitOps deployments are generated through layers of templating - Helm charts, Kustomize or ApplicationSets. Modifying these abstractions and trying to mentally render the output is error-prone. This talk introduces a method that uses Argo CD itself to render accurate diffs of Helm charts and Kustomize overlays between branches and posts the result directly on your pull request. We'll walk through a production setup using the Argo CD Operator, Argo CD Diff Preview, and GitLab CI, optimized for performance, minimal maintenance, and security. Through real-world use cases, we'll show what issues this approach catches before they hit your cluster. Thomas Hanser (Untis GmbH) **The Untis Platform Engineering Journey: GitOps Multi-Tenancy with Flux, GitLab, and Friends** Operating in the European education sector means juggling compliance, student privacy and massive traffic spikes when school starts. Historically at Untis, keeping this running in production was the burden of a single operations team. This session details our transition to an automated, multi-tenant GitOps platform managing a fleet of internal and external Kubernetes clusters. We share our approach of building a platform that gives product teams actual autonomy without compromising on security or control: * **Structured Multi-Tenancy:** Mapping GitLab groups to namespaced tenant projects using Flux’s multi-tenant model. * **Secure Access Control:** Leveraging the GitLab Agent for Kubernetes to enable scoped, declarative self-service cluster access. * **Flexible Delivery Models:** Supporting multiple decentralized deployment strategies by balancing governance and freedom for both internal teams and external guest environments. Prepare for an honest demonstration of challenges like managing secret lifecycles across a growing fleet, moving from script-driven tenant onboarding to true automated self-service, and wrestling with the classic "chicken-and-egg" problems of bootstrapping Flux and handling GitOps release management.

**Die absurdeste deutsche Comedy-Show Wiens: jung, wild & unberechenbar. Gratis Eintritt – jeden Donnerstag im Comedy Pub.** # [Hol dir deine Tickets hier!!!](https://www.universe.com/events/comedy-sein-vater-absurd-witziges-stand-up-open-mic-thecomedypub-tickets-CZ89PB?ref=MeetUp) Willkommen zu **Comedy sein Vater**, der Show, die klingt wie ein Meme und sich auch so anfühlt. Jeden Donnerstag im *The Comedy Pub* übernehmen junge, wilde Comedians die Bühne, um mit absurden Ideen, schrägen Gags und gnadenlosem Humor das Publikum zum Lachen (und manchmal auch zum Kopfschütteln) zu bringen. Hier gilt: nichts muss, alles kann. Von wahnwitzigen Gedankensprüngen über dunklen Humor bis zu völlig chaotischen Auftritten – **Comedy sein Vater** ist das Open Mic, bei dem Regeln aufhören und die Absurdität beginnt. Wer brave Comedy will, geht woanders hin. Wer das Unerwartete liebt, ist hier genau richtig. ## 🤔 Was ist ein Open Mic? Ein Open Mic ist die Spielwiese der Stand-up-Comedians. Hier werden Ideen geboren, getestet und manchmal auch sofort wieder beerdigt – live, unzensiert und direkt vor Publikum. Genau deshalb ist es so spannend: du erlebst, wie Stand-up entsteht, wie Comedians Risiko eingehen und wie oft daraus die lustigsten Momente des Abends werden. Bei **Comedy sein Vater** ist das Ganze noch ein Stück extremer: mehr Mut, mehr Chaos, mehr Überraschungen. ## 🍻 The Comedy Pub – Zuhause für Chaos & Lacher Austragungsort ist das **The Comedy Pub** (Kettenbrückengasse 7, 1050 Wien) – ein Irish Pub mit Herz und einem historischen Altbaukeller, der wie geschaffen ist für wilde Stand-up-Abende. Oben wartet die Bar mit Drinks und Pub-Atmosphäre, unten der Keller mit Underground-Flair. Niedrige Decken, warme Lichter, intime Stimmung – genau der richtige Ort, um Comedy an ihre Grenzen zu bringen. Dank der U4-Station **Kettenbrückengasse** gleich ums Eck ist die Anreise so einfach wie ein Lacher auf einen guten Witz. ## 💡 Eintritt frei – Spenden willkommen Hier gilt: Lachen kostet nichts, aber wer lacht, sollte geben. Der Eintritt ist frei, Spenden sind willkommen. Jede Reaktion des Publikums – ob Applaus, Gelächter oder betretenes Schweigen – hilft den Comedians, besser zu werden. Aber wer herzhaft gelacht hat, darf das auch im Spendenhut zeigen. ## 🎟️ Regeln für das Publikum Ja, auch im Chaos braucht es ein paar Spielregeln: * Sei pünktlich – sonst verpasst du den besten Wahnsinn. * Respektiere die Bühne – auch wenn’s absurd wird. * Lachen, Stöhnen, Kopfschütteln – alles erlaubt, aber bitte keine Zwischenrufe. * Kein Heckling – das endet nie so lustig, wie du denkst. * Spenden sind Liebe – und Comedy sein Vater lebt davon. ## 🎉 Warum Donnerstag? Weil am Donnerstag alles passieren darf. **Comedy sein Vater** ist das perfekte Ventil für Wochenend-Vibes, die schon zu früh kommen. Hier siehst du Comedians, die an die Grenze gehen – mit Humor, der nicht brav sein will, sondern mutig, absurd und manchmal gnadenlos ehrlich ist. Wenn du eine Show suchst, die dich überrascht, irritiert und garantiert zum Lachen bringt, dann bist du hier genau richtig. Willkommen beim Chaos.

FlashAttention is one of the most important pieces of software infrastructure for both training and serving any relevant AI model on cutting-edge GPUs. Let's have a look under the hood. The paper comes with a blog post that may be easier to read: [https://tridao.me/blog/2024/flash3/](https://tridao.me/blog/2024/flash3/) Find the paper here: [https://arxiv.org/abs/2407.08608](https://arxiv.org/abs/2407.08608) We are trying out a new Location -- right at the Westbahnhof IKEA. Take the elevator to the fifth. We may relocate if it is too crowded. Please Text me if you are late and can't find us. \-\-\- Bring your own printout or pdf-on-a-gadget. If you didn't have the time to read the whole paper, it is sufficient to be able to pretend to have sort of skimmed it. \-\-\- Want to suggest a paper, an event location, or just stay in touch with regular members? We hang out at the following Matrix server: [https://matrix.to/#/%23pwl-wien:rend.al](https://matrix.to/#/%23pwl-wien:rend.al)

If you are curious to know about what Notion can do this meetup is for you. **Speakers:** Philipp Stelzel, Nooa Adams and Beatrix Beer **Agenda**: We will present a workflow in **two different AI environments** — **Notion AI** and **Claude** — where an **AI agent turns AI meeting notes into a draft offer** (positioning, outline, and key messaging), and we’ll compare the process, the results, and the **credits/tokens consumed** while producing the same outcome. Philipp will demo the workflow using Notion AI and we’ll track how many AI credits it consumes along the way. Nooa will run the exact same workflow in Claude so we can compare results side-by-side and see how the credit usage differs. Beatrix will present in German about „Mehr als Mails und PDFs – mit einem Notion-Kundenportal zur Premium-Kundenbetreuung“ **Afterwards**: Drinks, food, networking, template swaps, and questions answered. Join us, meet fellow Notioneers, and level up your workflow

This time we’ll meet in Stadtpark for a portrait session / workshop, with plenty of time to experiment and work in different light situations. It’s a great opportunity to practise working with natural light outdoors, work with a model, and also get a few portraits for yourself. We’ll start with simpler portrait setups and then move into more creative and experimental directions as we go. Each person will have time to photograph the model but can also practice on the side, try different approaches, and also jump in for quick portraits in between. The idea is that we rotate setups a few times and explore how light, background, and small changes in direction affect the image. We’ll have a model with us throughout the session. Donation fee: 5€ Feel free to bring snacks and drinks — it’s a relaxed, open session. To join the community or ask any questions, you can use the Telegram chat: [https://t.me/+_xMTFu0BKaoyYzVi](https://t.me/+_xMTFu0BKaoyYzVi) **What To Bring:** * Your Camera * Potentially some light * A few Ideas for photos **To see examples of my works you can follow these links:** 🔗 [Behance](https://www.behance.net/fedorvasilev) 📸 [Instagram](https://www.instagram.com/phfedorvasilev/) 🔗 [My Website](https://www.phfedorvasilev.com/)18

En esta ocasión nos vamos a reunir en The Long Hall Bar, un pub irlandés en Florianigasse 2, 1080 Wien. https://thelonghall.at/ The Long Hall Bar tiene una amplia terraza, y por lo tanto no vamos a tener problemas de espacio. Para este evento Stuart Simpson ha hecho una reserva a su nombre para 25 personas. Como es la primera vez que nos reunimos en The Long Hall Bar, es conveniente llegar temprano. The Long Hall Bar, se encuentra a unos pocos minutos andando de la estación de metro U2 Rathaus. Este verano tengo la intención de celebrar el evento en distintos locales con terraza (así que si no vienes, te lo pierdes). Ante cualquier duda, especialmente si es tu primera vez, puedes mandarme un WhatsApp: +4369010297300. **Aunque el evento es gratuito, vuestras consumiciones no lo son.** En el último evento varias bebidas quedaron sin pagar y esto es algo que no es la primera vez que ocurre. Que este tipo de cosas ocurra, implica que cada vez me sea más difícil encontrar un local para realizar nuestro evento. Por eso **os pido encarecidamente que paguéis vuestras consumiciones**. Si los hechos se repiten me veré obligado a tomar medidas. El evento tiene la función de que nos juntemos para pasar un rato divertido. No olvides compartir el evento con otras personas interesadas. También tenemos un grupo de Facebook: [https://www.facebook.com/groups/426629184137458/](https://www.facebook.com/groups/426629184137458/) No olvides seguirnos en Instagram: [https://www.instagram.com/cafedelalengua/](https://www.instagram.com/cafedelalengua/)

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** *Customize the IDE: Building Extensions for Visual Studio Code* Visual Studio Code is one of the most widely used development environments today, and much of its flexibility comes from its extension ecosystem. Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!

**Improving Office in Franklinton** Physical location: Improving Office 330 Rush Alley Suite #150 Columbus, OH 43215 Schedule: 6:00 p.m.: Socialize, eat, and drink. Improving will be providing pizza and beverages. 6:30 to 8:00 pm. Main meeting and presentation(s). Topic: This month Chris Pazsint will be talking about Agentic Coding.

We meet on the last Monday of each Month. Presentations are given by members and friends of this group. If you would like to do a presentation (small or large) on a python topic, please contact Central OH Python at centralohpython@gmail.com

Our monthly PHP meetup. A virtual shindig courtesy of Zoom. Check back here for the details around 6:15 pm

Let's get together and listen to **[Eric Rico](https://www.linkedin.com/in/ericrico/)** from Unity3D (**From Joints to Gestures: Reading Hands in Unity**). A hand tracker gives you joints, not a gesture. This talk shows how you get from raw joints to a "thumbs-up" in Unity: the pipeline that cleans up the data, how a gesture becomes a few 0-to-1 values within tolerance, and why orientation matters as much as finger shape. Includes a live demo of tuning gesture thresholds. Eric also runs the **[Columbus Unity User Group](https://www.meetup.com/columbus-unity-user-group/)**. Check it out! ***Bring your laptop and expect to write some (non-AI-generated) code!*** Food and drinks will be available. **LOCATION:** 6515 Longshore Loop, Suite 300, Dublin, OH 43017 **FREE PARKING:** 6725 Longshore Street, Dublin, OH 43017

**Latest Dojo Location!** **Knotty Pine Brewing** 1765 W 3rd Ave, Columbus, OH 43212 We're going to try a new dojo location for a few weeks and see how it works Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead. We're looking for speakers for our Monthly Meetups! Fill out the form if you are interested in presenting to the Python Community. https://forms.gle/ehSfUAC2WgR34Crq9
