KubeCon is around the corner, and to get you in the mood for this, you get the next **Cloud Native Vienna Meetup** \- and this time\, we’re stepping into the "Upside Down\." Join us at [karriere.at](karriere.at) for an evening of deep-dive technical sessions and high-bandwidth networking. Whether you're hunting for Demogorgons in your logs or just trying to scale your Internal Developer Platform, we’ve got you covered. Agenda: * 17:30 - Doors Open * 17:55 - Welcome from the Organizers * 18:00 - Talk 1: Manav Singh ([karriere.at](www.karriere.at)) - homelabbing@karriere.at - Enabling Devs to Break the Cloud * 18:45 - Break / Networking * 19:00 - Talk 2: Andi Grabner ([Dynatrace](www.dynatrace.com)) - Stranger Platform Engineering: The Two Sides of Observability in Your IDP * 19:45 - Networking \-\-\- Manav Singh **Homelabbing@karriere.at - Enabling Devs to Break the Cloud** \-\-\-\- Andi Grabner **Stranger Platform Engineering: The Two Sides of Observability in Your IDP** Your Internal Developer Platform lives in two worlds. In the **Right Side Up**, developers rely on self‑service observability to build, deploy, operate and debug their apps. In the **Upside Down**, the platform itself must be observable to ensure its reliability, performance, and to understand usage patterns and adoption. **The twist?** these two worlds are not separate. Improving observability *of* the platform directly improves the observability *for* the applications built on top of it. Just like in *Stranger Things*, observability becomes the force that connects both realities—creating feedback loops, strengthening the platform’s foundations, and enabling teams to spot issues before they cross between worlds. This talk reveals why mastering both sides of observability is essential for any modern IDP. Expect real-world examples, a few supernatural analogies, and practical guidance you can bring back to your platform team—no Demogorgon hunting required

Join us for a nurturing and empowering in-person afternoon at **commonroom** for a form of networking going deeper. A local expression of our global **[Women Lead Community](https://women-lead-community.mn.co/),** each month we create a space for women to slow down, connect with themselves and others, and explore a new form of leadership grounded in **presence, purpose, and mutual support**. After a joint arrival, we take the time to reflect on our needs as well as what we each have to offer to the world. We have the opportunity to practice pitching our offers and needs in a safe space and connecting with other inspiring women who are eager to support each others growth. Just come as you are – curious, present, and open. No need to prepare anything. Bring a friend or meet new ones. Have something to write with you for the reflection and bring business cards and flyers of your offers, if you have any. The sessions are held in **English**. They are open to women of all backgrounds who are curious about co-creating a more conscious, caring, and connected world. If you are not yet part of the [Women Lead Community](https://women-lead-community.mn.co/) it would be amazing if you could sign up to our free community platform before the session. We encourage you to include your offers and needs in our virtual marketplace at the end of the session to reach even more women who could support you.

With the **AI Breakfast**, we’re creating a San-Francisco-style morning gathering for the Austrian AI ecosystem: casual, high-signal, no stage, no slides — just real conversations. This is an open exchange for decision-makers, deep tech builders, Clawdbotlers, founders, CIOs, researchers, public sector innovators and anyone actively shaping AI. Corporate meets startup, policy meets engineering, research meets product. The goal is simple: meaningful connections, sharp discussions, and cross-pollination of ideas — before 9am. Breakfast is ordered at your own expense. The table is reserved under **Cristian Hofmann** / **AI Austria**. Seats are limited. Your host Cristian Hofmann, Amin Khater & Ruben Hetfleisch will welcome you. 👉 Please only RSVP if you truly plan to attend 🙂

*Light is the subject. Everything else supports it.* **Extended Photography Workshop** Date: Saturday, 14 March (14.03.2026) Start: 16:00 Duration: approx. 4.5 hours Location\*\*:\*\* Vienna (exact meeting point shared after booking) *** This workshop is built around the transition from daylight to night. We’ll work with natural light first and then move into controlled artificial light, allowing you to experience how different light sources shape mood, contrast, and meaning. This workshop is focused on light — how to recognise it, shape it, and use it intentionally. In the first part, we’ll work with natural light, contrast, direction, and colour, and how these elements influence mood and meaning in a photograph. The second half will be dedicated to working with artificial light, as that helps even further to understand how to work with light. During the workshop I keep the focus on perception: learning to notice light before you lift the camera, and understanding how composition supports it. You’ll learn how to simplify scenes, work with shadows, and make conscious choices rather than reacting to what’s in front of you. The workshop is crucial as even professionals often do not use light to the full potential and I’ve seen many times when people working as photographers are forgetting about the most fundamental and complex part of it – light! Photo is light and here I explain ways to use it to your advantage ###### During the workshop you’ll * observe and analyse light before taking a photograph * practice seeing contrast, direction, and colour in real situations * shoot guided exercises focused on light, not subjects * review images together and talk through decisions * learn how to approach unfamiliar scenes with a clear visual intention ###### After the workshop You should feel more confident recognising good light, making deliberate choices, and understanding why you take a photograph — not just how. To book this workshop you can get in touch through my contact form. Please note that a 50% prepayment is required to secure your spot \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **To book the workshop and learn more about it you can visit:** [https://www.phfedorvasilev.com/photography-workshops-in-vienna/](https://www.phfedorvasilev.com/photography-workshops-in-vienna/) **And get in touch to book:** [https://www.phfedorvasilev.com/contact/](https://www.phfedorvasilev.com/contact/)

Hi Running fellows, Whether you’re a walker, new to running, a semi-pro, a marathonist or a sprint star - if you want to start your weekend in an active way and enjoy the outdoors in lovely surroundings with a fun, international and multilingual group of people, you are welcome to join us! Every Saturday at 9:30 am, we meet, we run, in the magnificent Schönbrunn park, and then we go for breakfast. Want to discuss politics or the best recipes for banana pancakes? Not a problem. Not feeling social? Tune out with your earbuds - we can talk over breakfast. We are casual. You can be too. What to expect: Start by meeting Adrian, Ali, Liz, Paul and Sonia on-time at 9:30am outside the Schönbrunn U-Bahn stop (exit Grünbergstraße). (Coordinates: 48.1858130, 16.3200640) From there, we walk to the side park entrance where the “running” part begins. The important thing is that you run at your own pace. Typically, small groups of people will run at the same pace as you, so you never have to walk/run alone :) We finish one hour later, at about 10:40am, reconvening just inside the Hietzinger Tor exit. (Coordinates: 48.1858825, 16.3032647). From there, we’re off to breakfast! Breakfast Details: Anker bakery opposite the U4 Hietzing station and depending on the weather, grab something for a picnic in Schönbrunn park, or hang out in the bakery. If you missed us earlier, you can always go there around 10:45. We are a fun group of runners who don’t take things too seriously. We meet, chat, RUN, stretch, chat, EAT and we hang out over a beer every now and then. It's that easy. Please join us for breakfast after the run! The more the merrier. Typically we are 10-30 people, as not everyone who comes signs up on meetup. Important disclaimer: Please only run as much as you feel you can, considering the temperature, weather conditions, your own fitness etc... run and walk at your own pace as the organizers do not assume any liability for any injuries or health issues. Sonia, Adrian, Ali, Paul and Liz

A Branch of the **Social Book Club** focusing on International Cinema. I try to host 2 film nights a month where I will find films based on the taste profile of the audience. We the Lovely Folks of the **Saturday Film Club, are back for the 23rd Edition** this Saturday! 🎬🌿🕊️ ☀️ We start at **18:30** hrs. Film chosen for this week is: 🎥 **The Metamorphosis of Birds** A quiet, poetic Portuguese film about family, memory, and the passage of time. Blending narration, stillness, and beautiful imagery, it tells the story of a father, a mother, and their children — unfolding like a dream or a remembered story. Tender, reflective, and deeply meditative. IMDb: 7.2/10 – Runtime: 1h 41m. 🍽️ Post Meetup Food at China Zentrum Stiegengasse! 😁😁 If you just joined, please fill up this survey so we can better tailor the films we show. [https://forms.gle/juPwhehSV2NosLee9](https://forms.gle/juPwhehSV2NosLee9) The event takes place at the Social Welfare organization called **MUT**. It is an organisation that works on social issues such as Emergency & Homeless Assistance, Food Rescue and Environment Protection. MUT is a non profit organization that provides us with the space to host the event. A small donation towards their cause helps them a lot.

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.

This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them. Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance". Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. 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. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.
