Intranets

Liebe JUG-Mitglieder, wir möchten Euch herzlich zu unserem nächsten Stammtisch, der jeden ersten Dienstag im Monat stattfindet, einladen. Alles weitere kann im unserem Blog unter http://www.jug-berlin-brandenburg.de/ gefunden werden. Viele Grüße Sandra, Jan, Jörg und Oliver

! All sessions in English except for 24.03, 21.04, 09.06, 28.07 & 01.09- these sessions will be in German ! Wanting to connect deeper with your partner? Looking for new ways to be intimate? Hoping to foster love, awareness, and communication in your relationship? Take some quality time away from the daily grid and explore Tantra together through embodied practice. The practice is designed to foster deeper intimacy, attunement and harmony between the two of you. Tantra invites you to allow your life force energy to flow without inhibition and to cultivate it for self-realization. Part of the practice is about inviting in more opening. Openness creates union, resistance creates separation. Deep connection, more pleasure and joy are a result of experiencing more openness. Tantra is for everyone! All couples are welcome regardless of sexual orientation and experience level. Not in a romantic relationship? Feel free to bring anyone you'd like to practice Tantra with. **What to expect:** * **Discourse, demo practice and Q&A**: learn about Tantra through discourse, ask your questions * **Tantra meditation practice**: presence, movement, sound and breath * **Sharing before and after practice**: share about your fears and desires & reflect on your experience * **Cozy studio setting**: enjoy a comfortable and intimate environment * **No partner-exchange:** practice only with your partner * **Fully clothed:** you may keep your clothes on during the entire practice **What to bring:** * Wear comfortable clothing * Water bottle to stay hydrated **Tickets:** 69€ per couple. Please purchase your ticket via [sophieheldens.com](https://www.sophieheldens.com/tickets?utm_source=meetup&utm_campaign=datenight) **Location:** Praxis Köpi Köpenicker Straße 175 10997 Berlin Kreuzberg Walk to the second courtyard and take the stairs to the front door on the left. **Please note:** Praxis Köpi is located on the 5th floor and there is no elevator available. Only book a ticket if you can walk the stairs. The benefit: a beautiful private studio with loads of natural light. **!! Please arrive 10 minutes early so we can start on time !!** Once we start the session, I can’t let you in anymore because it disturbs the class. Please do yourself and the group a favour by coming on time. Thank you! **Workshop facilitator** Hi! My name is Sophie. My passion for Tantra is rooted in a deep spiritual yearning and an inner knowing that Tantra is my path. My desire to teach Tantra has been sparked by having witnessed my own growth and healing as a result of these practices and it is inspired by a vision to create a more beautiful world. I create a space that is loving and nurturing, with a strong emphasis on ensuring that you feel save and supported. My workshops are gentle yet transformative, spiritual yet grounded and always heart-centered. I'm passionate about bridging the wisdom of ancient Tantra with modern-day practices.

Join our track sessions in Friedrichshain! Twice a month on Tuesdays we’ll gather at FSV Berolina Stralau 1901 e.V. at 18:30 (find us on the further side of track). Afterwards we‘ll have some drinks and food if we feel like it. Don’t worry if you are new! Joining track sessions is a great chance to start 😉 Take care and see you soon ❤️ P.S. ‼️️ Please cancel your participation if you can’t show up, even if it’s at short notice so that we don’t wait for you. Thanks! ‼️

For the June edition of our collaborative modeling meetup, we’ll continue the EventStorming deep dive we started earlier this year and explore some of the tactics and recipes of this format. What does that mean, exactly? Massive learning, massive fun, and massive numbers of sticky notes. As always, everyone is welcome. You don't need to be a software engineer to participate. In fact, it would be great to have more people who aren't software engineers. We're here to solve problems cross-functionally, not get into implementation details. As long as you care passionately about getting things right, then you belong here! This is a hands-on workshop. Be prepared to participate fully and add to the energy of the room. Looking forward to seeing you there!

Our training programme features flexible booking sessions that mix learning with competition.** **Our aim is to equip players for the game whether you're playing for fun or aiming for Grand Slam success 😎**

The state deals with a lot of money. People and organisations need to declare, file, and pay taxes or receive returns if they overpaid the state. Tax contributions amount to billions of euros, funding public goods such as infrastructure, education, social welfare, and defence. In the 13th edition of our meetup series, we take a closer look at research and design in public finance and taxation, exploring diverse perspectives from 3 speakers. The evening aims to spark a discussion about the government’s or the state’s role, and how it can be accommodating to citizens, residents, and business owners. We will hear from: * Manuel Großmann (Taxfix) * Merici Vinton (formerly US Digital Service) * Sonja Wilczek (DigitalService des Bundes) The federal government’s DigitalService is hosting the meetup on the mezzanine floor of its Kreuzberg office. All presentations will be given in English. Questions in the later discussion part can be raised in either English or German. The event is jointly organised and hosted by CityLAB Berlin and DigitalService.

We invite you to our [Digitale Leute Meetup in Berlin powered by SAP](https://www.eventbrite.de/e/dl-meetup-12-powered-by-sap-berlin-tickets-1987405580591?aff=oddtdtcreator).

Get your free ticket [here](https://www.eventbrite.de/e/dl-meetup-12-powered-by-sap-berlin-tickets-1987405580591?aff=oddtdtcreator) *** The Digitale Leute Meetup is an event series organized by *Digitale Leute*. **Invitation** We invite you to join us for our second meetup this year on June 4th at SAP in Berlin! We just celebrated the successful restart of our event series in Cologne with over 100 participants, and we cannot wait to dive deep into the Berlin product builders community. Look forward to leading professionals from product, engineering, and UX/design, sharing their best practices and discussing trends and topics with you the community. We are still early in our planning, but expect the first speaker announcements soon. Join us for an evening of networking, fueled by drinks and bites – just bring your ideas and your colleagues! **Schedule** 06:30 PM - Doors open 07:00 PM - Welcome by Christoph Bresler, Founder of Digitale Leute School 07:05 PM - Welcome by SAP & Moderation by Thomas Riedel 07:10 PM - DL Interview: **Mareike Dorra**, Head of Product Management Bootcamps at Digitale Leute School (ex-Zalando) will interview **Jan Hegewald**, VP Engineering at Rabot Energy (ex-SumUp, -Zalando, -Idealo) about the rise of Product Engineering. AI is changing how software is built. In this conversation, Mareike Dorra and Jan Hegewald explore why the focus is shifting from software development to product development—and how engineers, through product thinking, new tools, and closer collaboration with product managers, are evolving into “product engineers.” 07:40 PM - Questions & Answers 08:00 PM - Networking 08:55 PM - Wrap up of the meetup **Good to know** In addition to our meetup, we bring together over 1,000 product builders in Cologne every November at our international software product development conference, the Digitale Leute Summit. Speakers in 2026 include representatives from Atlassian, Google DeepMind, Zendesk, sevdesk, and many more. You can find more information here: [Digitale Leute Summit 2026](https://www.digitale-leute.de/summit/26/ "https://www.digitale-leute.de/summit/26/") **About Digitale Leute** Digitale Leute has always been about one thing: bringing together the people who shape digital products. The thinkers, the builders, the ones who care deeply about how technology is made and why it matters. Over the years, our community has grown – but we’ve missed the magic that only happens when you’re in the same room, sharing ideas, swapping stories, and sparking conversations that no Slack channel can replicate. So we decided: it’s time to bring our meetups back. **About SAP in Berlin** Located in the heart of European innovation, [SAP in Berlin](https://www.sap.com/germany/about/berlin.html "https://www.sap.com/germany/about/berlin.html") combines the power of a global company with the strength of a unique local ecosystem – we attract talent, shape SAP‘s image as a front-runner of innovation, and foster our position as market leader for enterprise application software in Berlin. Our location in Berlin offers a perfect meeting point for innovators and decision makers, while we stay on top of software trends and technologies to define their value for business and society.

From APIs to Agents: Control, Identity, and What Breaks Along the Way Most of what we've built over the last \~15–20 years assumes a static frame of reference: Apps talk to services over APIs. You know who's calling what, you can stick a gateway in front of it, apply some policy, and move on. Agents don't really fit that model. They don't just call an API and return. They decide what to do, call a tool, look at the result, call something else, maybe involve another agent, loop through an LLM a few times… all the while, doing onbehalf of the user, with permissions that aren't always obvious. It's not always clear who is actually doing something. It's not obvious what the full execution path looks like. And the access control models we're used to — user → service, service → service fall part. We'll dig into what actually breaks when you start wiring agents into real systems, especially around identity and access control. Things like: \- how \(or if\) you assign identity to an agent \- what it means for an agent to act "on behalf of" someone \- how you enforce policy when the flow isn't predefined \- and how you get any kind of visibility into what just happened We'll also look at some of the patterns starting to emerge: agents talking to other agents, tools being invoked dynamically, and why a mediation layer (ie, agentgateway) must be built from the ground up with this in mind. \-\-\-\-\-\- Speaker \-\-\-\-\-\- Christian Posta (Solo.io) Christian is a globally recognized expert in cloud-native architecture, service mesh, and distributed systems. As Global Field CTO at Solo.io, he works with enterprises to design and implement next-generation platforms—and is now at the forefront of AI-native infrastructure and agent systems. \-\-\-\-\-\- Who should attend? \-\-\-\-\-\- This meetup is for people who are building or thinking about the next generation of enterprise systems: Platform engineers and architects, Cloud-native practitioners, AI engineers working with agents and LLMs, Anyone exploring how AI changes system design \-\-\-\-\-\- How to join \-\-\-\-\-\-\- This time, the meetup will be in the premises of Riverty in Kantstrasse 17, Berlin (4th Floor of Living Berlin mall).

**This is 100% non-profit. The 15€ sign up fee for everyone is only to minimize last-minute cancellations. The total sum goes to a bar-tap that everyone can use to order drinks until the amount is used up. ‼️NO REFUNDS‼️** **‼️Please don't just show up without RSVPing here and paying the 15€. We have a separate room that has limited capacity and a specific drinks agreement with the bar - so splitting up the bill won't become a mess.‼️** **Small update on how your money get's used from May 2024 onwards:** As of this month, meetup.com has started charging me 34€ instead of 16€ per month. I've decided to distribute this fee evenly among all us participants every month. Example: In the last 12 meetups, the average number of attendees was 17. With 17 attendees I would effectively collect 230€ (after fees). I would now substract 34€ leaving us with 196€ that go to the bar. 15% get's tipped to the wait staff, in this case 30€, leaving us with 166€ effectively to order drinks. Hope everyone is cool with this system. :) Website: https://www.pberg-engineers.me WhatsApp groups: Please come and join us on WhatsApp! \- "PBerg Engineers \- NEWS" \- Only organizers can post announcements or polls \-\> https://chat\.whatsapp\.com/EqMJMmlCZO6LOOfAoG4yTj \- "PBerg Engineers \- DISCUSS" \- Everyone can post \-\> https://chat\.whatsapp\.com/LPuo76J83gF6IZMLUcM4u2 Please join those groups now if you're interested. :) All skill/education-levels welcome! :) Lightning Talks: \- TBD We'll also have a brief "Jobs: Lost & Found section". **Location:** From the street you will have to enter the right hand Cafe Chagall (yes, there are 2).

**⚠️ IMPORTANT: REGISTRATION MANDATORY ⚠️** Registration on **Luma** is **REQUIRED** to attend this event. **Link: https://luma.com/7zfk3orp?utm_source=meetup** Your registration is subject to host approval. You must complete the registration process on lu.ma to receive the full event location details and confirmation of your attendance. **Please note: Without approved registration on Luma, you will NOT be able to access the event location or attend.** We are excited to host a **BLISS x juna.ai workshop** featuring **Dr. Nima Siboni (senior RL Engineer)**, who will guide us through an interactive session on algorithm discovery with LLMs. **​​​ Title: The Heuristic Scientist: Open-Ended Algorithm Discovery with LLMs** **📅 Date: 03.06.2026** **🕕 Time: 18:00** 📍 Location: TU Berlin Marchstrasse 23 [Room 0.011] ​​​The session will last around 2 hours, followed by a networking session with juna.ai and fellow AI enthusiasts (and free pizza!🍕). Bring your laptop! **​Abstract:** Large language models are increasingly useful not only for writing code, but for exploring the space of possible algorithms. In this hands-on workshop, we will look at how LLMs can act as “heuristic scientists”: generating candidate strategies, turning ideas into executable code, testing them against concrete objectives, and refining them through feedback. The workshop centers on the general discovery loop behind LLM-assisted heuristic generation. Participants will learn how to structure problems for algorithm discovery, prompt models to propose interpretable heuristics, evaluate those heuristics with simulations or benchmarks, and use the results to guide further search. We will also discuss when simple prompting is enough, when training or fine-tuning may help, and how to keep generated heuristics understandable, testable, and auditable. ​By the end of the session, participants will have built a small discovery loop of their own and will understand the practical trade-offs involved in using LLMs for open-ended algorithm discovery: creativity versus control, exploration versus verification, and automation versus human judgment. ​ **⚡ FINAL REMINDER ⚡** **You MUST register and be approved on Luma to attend.

Monthly working lunch for Columbus business owners. One specific topic, one to three actions you can run this week. You can be the best at what you do and still be invisible. If local buyers cannot find you, the phone does not ring. Marketing Monday Lunch + Learn is a monthly working lunch for Columbus business owners focused on building relationships, local networking, and local marketing. Every kind of local business welcome. No pitch round, no pressure, no upsell. **This month** Most local businesses pick one or two places to be visible and call it good. The result is inconsistent calls and a feeling that marketing is not working. We will walk through the three places every local business needs to show up, plus the fourth place most owners ignore that quietly produces the warmest leads. **What to expect** Doors open at noon. Order lunch and drinks at the cafe counter or bring your own. You get real conversation with other local owners and a focused marketing lesson. You leave knowing people and with one to three actions to run that week. The room is reserved through 1:30 PM. **Who this is for** Any local business owner who wants clearer marketing direction and real local relationships. Service businesses, retail, home services, professional services, online owners building local presence, anyone serious about being part of the Columbus business community. **Not the right fit if** You are here to pitch the room or recruit for an MLM. **Details** * Second Monday of every month * 12:00 to 1:30 PM * Good Cafe Easton, 4400 Easton Commons, Ste 150, Columbus, OH 43219 * Order lunch and drinks at the counter when you arrive * Free to attend, RSVP required, space is limited **About the host** Rita Suzanne is a local marketing strategist and the founder of Local Marketing Method.
