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 invite you to an interactive workshop hosted by LISS x Semrush and led by **Saeid Nobakht, Lead AI Engineer at Semrush**, focused on bringing agentic AI into production. The session will last around 2 hours, followed by a networking session with Semrush and fellow AI enthusiasts (and free pizza 🍴😋🍕!). Bring your laptop! And please arrive a bit early to get settled :) **Schedule** * 17:45 - Doors Open * 18:00 - Start of Workshop * 20:00 - Networking + Catering **Abstract** Building reliable agentic systems requires more than evaluating individual LLM outputs — it demands a systems-level approach to testing, observability, and operations. This session covers how to design evaluation frameworks for multi-step, tool-using agents; how to instrument and trace agent decisions for debugging and audit; and how to recognize and respond to common production failure modes. **Who is this for?** This workshop is open to everyone curious about building with agentic AI. Technical background and Python knowledge recommended. **⚡ FINAL REMINDER ⚡** **You MUST register and be approved on Luma to attend.

Come join us on playing the small astro outdoor pitch with walls and goals at Jahn-Sportpark. Like inside Hallenfußball - but outside! We play 4vs4 or 5vs5 with up to 2 sub each team. Fun Fun Fun! Do you like to play football - but relaxed and not with competitive or aggressive players? Are you a bit lazy, a bit old, a bit unfit or just not so talented? Are you tired of over-competitive emotional bros who only want to show off their skills and desperately need to win? **Then [Lousy & Lazy Football](https://www.instagram.com/landlsc/) is the right thing for you!** We are a group of friendly people who just want to have a relaxed kick. All genders, ages (18+) and nationalities welcome. Note: **We** only play with "Multinocken" (multistuds) or shorter. Please have a look here: [link](https://www.11teamsports.com/de-de/fussballschuhe/multinocken/). Rules for lazy & lousy football 1. **Don’t be competitive** 2. **No hard tackling/sliding challenges** 3. **Support new and less skilled players by giving them the time and space to play the ball, dont intercept passes to and from them** 4. **Don’t dribble past multiple players (trying to take on one player is fine).** 5. **Don’t close down the defenders too quickly. Give the team a chance to play the ball out.** 6. **Rotate the goalkeeper** 7. **Be a teamplayer, pass the ball.** 8. **We enjoy shooting goals, but we dont count them. Winning / losing doesn't matter.** This meetup is for members of the Lousy & Lazy Sport Club. If you want to try out our lousy & lazy sport events, you can do a trial run (Probetraining).

The Language Café is primarily aimed at people who are struggling with their mental health which can make it hard to go to regular courses. We want to create a safe space for everyone to learn and practise without pressure. Everyone is welcome! Please try to be on time so we can all get started together :) We mainly practise on a beginner/lower intermediate level and adapt to everyone's prior level of German. The Language Café will focus on teaching you the most important words and phrases and basic grammar in German. The content of the course is adapted to real life. (everyday life in Germany, dealing with authorities, etc.) We will cover different topics every week and you can join us anytime, since the topics do not necessarily build on each other. The Sprachcafé is for free. \*If you cannot make it please cancel your participation so someone else from the waiting list can join, thank you!\* \| \| \| \|

**!If you cannot belay, please contact us on the Telegram group!** Here is our Telegram group (to be protected against bots): https://tinyurl.com/BerlinClimbingMeetup2 **Safety:** **If you cannot belay, please contact us on the Telegram group about this and we will put you in a group with experience people. That way, if you cannot belay you can still come and climb with us. We are not allowed to teach anyone how to belay or refresh someone's belaying skills. If you have not belayed in the last 6 months or more, we recommend you do not attempt it here without taking a formal refresher course first.** Join us for some Sunday afternoon climbing at Magic Mountain. We will spend the afternoon climbing - lead and top rope followed by a meal afterwards. The Plan: 4:00 - 8:00 climbing 8:00+: Potential hangout (sauna from the gym, drinks. local restaurant) depending on the mood of participants Gear: You can rent all the gear you need - shoes, chalk and a harness. Finding the group: We will either be waiting outside on the wooden chairs or hanging around reception (if the weather is bad). If you're new to the group, I'd recommend trying to arrive on time or a bit in advance. Please use the link below to join our Telegram group and send us a message if you have trouble finding us. Note: We are not a "Magic Mountain" official Meetup, the hall has its own meetups, we are an independent group with events in different halls. So don't be confused if some of the reception people don't know about the meetup or tell you it happens on another day. :) In addition, while the event is free you will need to pay the entry to the gym and the rental equipment if you don't have it.

**Labor: Past, Present, and Future – Work, Power, and Purpose** Labor is a defining force of human life. It shapes how we survive, how societies are organized, and how power and resources are distributed. Work can provide stability, dignity, and meaning—but it can also lead to inequality, exploitation, and exhaustion. More than just an individual experience, labor is a collective reality that reflects the structure of our world. At its foundation, labor is tied to survival. Like all living beings, humans must expend energy to sustain life. Our bodies and minds are wired for effort, cooperation, and problem-solving. Yet human labor goes far beyond biology—it is structured by economic systems, cultural values, and political decisions that determine who works, how, and for whose benefit. Across history, labor has continuously evolved—and so have the struggles surrounding it. Workers have organized to demand rights, protections, and fair wages, giving rise to unions, movements, and political parties. In many countries, labor movements shaped modern democracy, from the Social Democratic Party of Germany in Germany to the Labour Party in the UK, alongside similar movements across Europe and beyond. These efforts are remembered and celebrated globally on Labor Day. Labor is not only a human phenomenon. In the natural world, cooperation, division of roles, and collective effort are essential for survival—from insect colonies to social mammals. These systems offer a broader perspective on work as something deeply rooted in life itself, while also highlighting what makes human labor unique: its complexity, inequality, and capacity for change. In today’s world, labor is undergoing rapid transformation. Automation, digital platforms, and globalization are reshaping traditional employment. Stable careers are giving way to flexible—and sometimes precarious—forms of work. At the same time, the psychological experience of labor is becoming more visible: questions of burnout, motivation, identity, and purpose are central to how people relate to their work. Looking ahead, the future of labor may challenge long-held assumptions. Artificial intelligence and robotics could significantly reduce the need for human labor in many sectors, while increasing demand in others. This raises fundamental questions: What is the role of work in human life? How should wealth be distributed? And how do we define purpose in a world where labor is no longer central to survival? We will explore how labor has evolved through history—from early forms of work to modern economies—and how worker movements and political forces like the Social Democratic Party of Germany and the Labour Party shaped rights and social change. We’ll also reflect on labor as a biological, psychological, and social experience—how effort, motivation, and cooperation shape both humans and the natural world—and how work today is being transformed by technology, from gig economies to automation. Finally, we’ll look ahead to the future of labor, asking what happens if work changes fundamentally, and how we might rethink purpose, fairness, and the role of labor in our lives. Join us for a critical and engaging discussion on labor—not only as work, but as a force that shapes society, identity, and the future. Together, we’ll reflect on how labor defines our lives today and how it might be reimagined tomorrow. *** 📅 Event Details 🗓️ Date: Saturday, 18 April 2026 ⏰ Time: 14:30 📍 Location: Hardenbergstraße 10, 10623 Berlin 📱 WhatsApp: For prep materials and directions (Group Chat) [Group Chat](https://chat.whatsapp.com/Ba8ZAaH2Yuk6FGmD3LLO7H)

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee.

**Caller: Richard Ades** **Band: The McKenzies** **Clinton Heights Lutheran Church** **15 Clinton Heights Ave, Columbus, OH 43202** WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing! Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor. Be sure to come for the beginner's lesson from 7:30 - 8:00, followed by dancing 8:00 - 10:30. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner. Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot. For more information contact me or check out our website: [www.bigscioty.com](http://www.bigscioty.com/) Please bring your own refillable water bottle.

Over time I'm hoping to organize a hike to all the Franklin County Metro Parks. This is the first one so if you're interested jump in! We'll start with the Canopy Walk, a cool feature of this park. Climb 100 stairs to the top - or take the elevator if stairs aren't your thing. At the top there are a bunch of things to play on - a rope bridge, a fireman pole that we can slide down - and more! About fifteen minutes there and we'll head to the natural trail, Buttonbush, Maple and Beech Trail for 2.2 miles then do a 1.7 mile loop on the paved Greenway Trail. We'll be passing our cars as we transition if you only want to do the first loop, or the second loop. Pace of around 3.5 mph but no one left behind. If there is an interest we can grab lunch nearby afterward.

Bienvenue! Columbus French Conversation group invites you to our Saturday morning French conversation club. Expect a casual and welcoming atmosphere in which to learn french! I will bring my laptop so we can look up new vocabulary as needed! The venue is a beautiful French restaurant so you can really get into the zone :)
