Graph Theory

Some friends of PyData are organising the following event, and we think it would be great to share it with the community. Pixels2GenAI is an exhibition by software developers creating computer art. We have used equations, algorithms, and AI models to generate images and installations. The artists explore the space between hand-programmed images, the aesthetics of mathematical rules, and AI as an art-making tool. Works by the following artists will be on display: * Burak Kağan Yılmazer * Sara Maras * Alexander Hendorf * Hansu Kim * Maris Niewenhuis * Ewa Rother

**Music Therapy & Systemic Psychotherapy** My approach integrates music therapy and systemic psychotherapy to support emotional expression, connection, and transformation. Through sound, improvisation, and dialogue, we explore inner experiences, family dynamics, and relational patterns in a safe and creative space. The sessions invite awareness, playfulness, and presence — allowing music to become both mirror and bridge between what is felt and what can be spoken. Whether through active musicking, deep listening, or verbal reflection, the process unfolds at your own pace, weaving together body, voice, and relationships as pathways to healing and growth.

Nice! You are looking for real long time friendship! You might have already lived in Berlin or other big cities and experienced the "Anonymous" culture for a while. Meeting random people over and over and never see the same person again! In order to find "Real Long Term Friendship" in Berlin, do as follows: * You should not care how many people are joining this meetup. You RVSP. Even if only one person is joining. Because if everyone are waiting for everyone else to RVSP, nobody joins and nobody finds a new friend. * You do not care how many people of the opposite sex are joining. You are looking for friends. Finding the best romantic partner in the world, while avoiding not very attractive others, can be your other goal, for another time. Here we are looking for Friends. Real ones. * You are going to risk a very precious property of yours: Your time! Yes, there are thousands of opportunities in Berlin, there might be a rock concert for free, a birthday party you might miss, an important person might call you and invite you spontaneously, but you never find new friends until you decide to risk your time and meet people anyway. "I will check my calendar and get back to you" also does not work. Commit your time and spend it. Trust me, you won't go bankrupt ;-) * You are ready to use your phone as a real phone! You might have been using your phone as a tablet to visit Instagram and Facebook and watch movies. But if you want to find friends, you must know that people might take your phone number and give you theirs. That means they will Call you! And you have to pick up the phone and answer it. If you want to find new friends, you must be ready to do something really hard for the first time after years: Call people first, and if they called you: Answer your phone! * You are going to meet some people twice! That's the point of friendship. We already can experience random encounters with random people in random places one at a time. But that is not called friendship. If you want friends, you must be ready to meet the same person more than once. If you agree with above, RVSP and COME! You will meet other people who think the same way. P.S: Now that you've read all the way down to here, I suggest you [watch this animation](https://player.vimeo.com/video/547249272?h=22f3dd0f6f).

Sunday will hopefully be a sunny day. We’ll meet at S-Bahn station Grünau, on the sidewalk level inside the station (exit Adlergestell/Wassersportallee). We will hike this tour: https://www.komoot.com/de-de/discover/S%E2%80%91Bahnhof_Berlin-Gr%C3%BCnau/@52.4128380,13.5736270/tours?sport=hike&map=true&toursThroughHighlight=388182&focusedTour=1268215602&pageNumber=1 , but make a shortcut in the middle of the tour. Please prepare for a rather speedy hike. (Bring comfortable shoes, for instance.) There are no cafés or restaurants along the way, so bring your own food and drinks. If you need to contact other participants during the hike (for example, to find out where to meet us if you are running late), please use the Signal group link that I will send to all participants via private message three hours before the hike. This timing is intended to prevent non-participants from misusing the link for unwanted advertising, which has happened in the past. Signal also allows us to share our locations during the hike without involuntarily forwarding this information to the intelligence services of authoritarian or non-authoritarian states. For all other purposes, especially socialising and posting photos, please use the Telegram subgroup 'Event Chat & Photos': https://t.me/addlist/KAOk2PA4BDE0ZTY8 . The hike will take place if at least 6 people sign up. As long as there are more than 6 people, you can sign up and cancel as many times as you like. If there are 6 or less people, please avoid cancelling, as this might make the other participants feel insecure about whether the hike will take place (or whether there is something wrong with the hike and they should cancel as well --> [Matthew effect - Wikipedia](https://en.wikipedia.org/wiki/Matthew_effect)). If there are less than 6 participants, the hike will also take place unless the majority of the participants are in favor of canceling the hike.

Thank you for helping us keep our origami community respectful, reliable, and fun! 🙏 Get in touch if you have questions anytime and see you all at the folding tables very soon! 🇩🇰

We meet and sketch each other in Berlin. This is just an art gym that we also exercise our social skills. Afterwards usually we go for lunch as a group. **How Does It Work?** This event is simple, we meet and sketch each other doing portraits. Most of the participants use pencils or watercolors. Main aim is to socialize while we draw. There will be plenty of time to talk and get to know each other. We have to mention that this event is suitable for all levels. Many have started to draw in our event actually. **Structure** A. Warmup Phase: We pose to each other for 1 minute. B. Main Phase: We pose to each other for 10 minutes. C. Showcase Phase: We show some of the drawings we did to each other. **Who We Are** Creative Sessions is an art events group located in Berlin. **Is it Free?** The event is free of charge. It is advisable to get a drink though. This is a cafe, we need to have at least half of the people on each table with a drink. They accept only cash and most hot drinks cost from 2.50 to 3.50. **How to help or donate?** The event is provided for free but many people help this be a regular thing. We also need people to volunteer and help for minor tasks like the serving of the drinks or cleaning up. Just send us a message. If you want to donate and keep this event from happening, via Paypal to the host (Miltos) : https://ko-fi.com/miltosthings/ **Art Materials?** Bring your own art materials. **Our Instagram Profile** Follow us on instagram @icreativesessions Use the hashtag #icreativesessions on your post description there to find out drawings from the event!

Hey, Sonntag ist es wieder soweit. Wir gehen am Lietzensee spazieren, bilden Zweiergruppen und wechseln uns ab. Treffpunkt: VOR dem Restaurant Rocco.

Freuen uns auf eine nette Truppe.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

Join us for a casual chat over coffee & tea at Grandview Grind! Come out and meet some new people, enjoy your favorite drink, and make some new friends!

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. We will be hearing from Becca Powell, Director of Advocacy and Outreach at Unchained At Last, an organization whose mission is dedication to ending forced and child marriage in the United States through direct services and systems change. Unchained At Last's mission clearly meshes and addresses several of our Humanist Ten Commitments. Becca will educate us about an issue many of us may not be familiar with--but should be. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Going forward our meetings will be hybrid.
