Open Dialogue – Discovering Together in Vienna
We will meet in a calm and friendly place ( Parc, Café, Restaurant) to explore together some of Jiddu Krishnamurti’s key questions about awareness, relationship, and freedom.
There will be no teaching, no authority — only open dialogue and attentive listening.
Everyone is welcome, whether you are familiar with Krishnamurti or simply curious about life and self-understanding.
We’ll start with an open conversation around a theme such as “Listening without judgment” or “Can thought bring clarity?”
Please bring openness, curiosity, and a readiness to listen — no books or notes needed.
The spirit is not to discuss “what should be,” but to observe together “what is.”
BACHATA Sensual Technique
Discover Bachata Technique classes at Lento Dance Vienna – one of the city’s leading dance schools. Guided by internationally certified teachers with over 15 years of experience, our classes offer a welcoming environment where you can refine your technique, boost your confidence, and elevate your social dancing.
Run+B-fast
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

Science and Philosophy Discussion Table
This is a group for meeting new people, eating brunch, and having discussions about science, life, philosophy, politics, and people.
Anybody is free to join, and we charge no fees.
This discussion group aims to have the absolute minimal level of structure necessary to ensure the conversation remains engaging to the majority of people present. In particular, we \*don't\* have fixed order of speaking or timed statements.
So far, the balance we've struck is enforcing hand raising when conversation gets intense in order to minimize interruption, and to give the chair (me!) the power to occasionally call a snap election on the conversation topic.
Sunday Session - Showcase & Jam
Come join us for the showcases of Lisa Lynn's workshops. We will see pilots from the "Improvised SitCom" and a short intermission of "ACAPROV" - improvised acapella music.
In the second half we will have an improv jam where we will draw names form a hat - so you can play funny games and do some scenes with your fellow improvisors. Come an join the fun!
Ne entry fee, but we will ask for a donation!

Ecstatic Dance - Inner Serenity
**Ecstatic Dance – Inner Serenity**
Stille im Inneren · Klarheit im Herzen · Frieden im Körper
Am **Sonntag, 01. März 2026 um 18:00**, öffnen wir den Raum für Inner Serenity – eine Einladung, durch Bewegung, Klang und bewusste Präsenz zu deiner inneren Ruhe zurückzufinden.
Inmitten von Wandel und Geschwindigkeit erinnern wir uns an jenen stillen Ort in uns, der unberührt bleibt.
Ein Abend, der dich einlädt, Anspannung loszulassen, den Geist zu klären und dich wieder mit deinem natürlichen Gleichgewicht zu verbinden.
Ecstatic Dance wird hier zu einer sanften und zugleich kraftvollen Reise – vom bewussten Ankommen über einen lebendigen Tanzbogen bis hin zu tiefer Integration.
**Mitwirkende**
🌿 **Sabine Sonnenschein – Tanzeinleitung**
Sabine liebt, lebt und unterrichtet die Verbindung von kaschmirischer tantrischer Weltsicht und Tanz als Lebenshaltung. Für sie ist Ecstatic Dance nicht nur individueller Ausdruck im Moment, sondern das bewusste Spüren eines gemeinsam kreierten Miteinanders.
🔥 **Shamantra aka. DJ Kobayashi – Ecstatic Dance DJ Set**
Downtempo und tribal beats – sehr rhythmisch, mystisch und tiefgehend.
Mit langjähriger Erfahrung als zentrale Figur unserer Community besitzt er ein feines Gespür und das Talent, Menschen genau dort abzuholen, wo sie stehen – und sie in einen kraftvollen, organischen Tanzfluss zu führen.
🌺 **Darkfeatherbird – Sound Journey**
Eine der einzigartigsten Stimmen, die zu tiefer Innenkehr einlädt. Songwriting, das Verbindung schafft. Sanft, hochwertig, herzöffnend, tiefgehend und rein – ihre Klänge tragen in eine innere Stille und klare Integration.
📍 **Sonntag, 01.03.2026**

Humanist Program: Fighting the Efforts to Insert Religion into Public Education
The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event.
Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk.
Our March speakers are Molly Gaines and Zack Parrish, co-organizers of the Secular Education Association:
They will share their story of how a small group of Ohio parents grew into a national organization tracking released-time religious instruction and other church–state issues in public schools. The presentation will cover SEA’s early wins and hard lessons, what we’re seeing nationally right now, and how local advocates can play a meaningful role in protecting public education. Attendees will leave with a clearer understanding of the landscape — and practical ways to get involved.
Going forward our meetings will be hybrid. You can meet us in-person or attend online

CBusData - Discover the Power of Window Functions
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.
