Deep Reinforcement Learning

Liebe Freunde des gesprochenen Wortes, Ob es darum geht, ein Meeting zu leiten oder im Familienkreis einen Toast auszusprechen – diese Situation vor Menschen zu stehen und etwas zu vermitteln kennt so gut wie jeder. Wir lernen gemeinsam, dabei gelassen und souverän zu bleiben, wertvolle Informationen zu transportieren und unser Publikum zu begeistern. **Was macht unseren Club besonders?** Unser "Mut und Rede" Club trägt nicht umsonst seinen Titel: wir pflegen einen wertschätzenden Umgang miteinander, sodass die Hemmschwelle möglichst gering ist, sich selbst auf die Bühne zu trauen. **Wie läuft so ein Clubabend ab?** Es warten vorbereitete Reden auf euch, aber auch ihr habt die Möglichkeit in geschütztem Raum eine spontan improvisierte freie Rede von 1 bis 2 min vor Publikum zu halten. Das klingt vielleicht im ersten Moment etwas abschreckend – aber es ist eine ganz tolle Erfahrung über sich selbst hinauszuwachsen. Und egal was passiert, ihr werdet immer für Euren Mut belohnt. Und es wird auch immer geklatscht. Wir freuen uns, Euch kennenzulernen! Hier findest du die genaue Wegbeschreibung: www.mut-und-rede.de/kontakt#anfahrt Um besser planen zu können freuen wir uns über vorherige Anmeldung: https://www.mut-und-rede.de Es findet grundsätzlich jeder Clubabend statt, auch wenn laut meetup nur wenige Teilnehmer zugesagt haben.

If you’re just starting out with watercolours—maybe you’ve painted a bit at home or followed a tutorial or two, but still feel a little lost—I think you’re going to like this! First, we’ll practice **wet-on-wet, layering washes, colour mixing, transparency** and more. After this first part of the class, once you’ve discovered a few watercolour effects, you’ll have time to practise them by applying them to simple shapes (animals, plants, etc.) that I’ll provide. With the help of examples—and my guidance, of course—you’ll practise alongside other watercolour enthusiasts, supporting and learning from one another. Feel free to bring ideas and questions about things you'd like to paint :) **No previous experience needed**—just curiosity and a willingness to explore. ### **Mondays 13 - 20 April** from 6:00 to 7:30 PM **In Friedrichshain**, Berlin (exact address by e-mail) Join us for one or both classes, as you prefer. They are independent but complementary. **Price:** * 27€ x class / 50€ x 2 classes Payment via PayPal / Bank transfer **Material:** Material for watercolours is very specific. If you use poor-quality or non-professional material, you won't achieve the optimal results. Please check this helpful guide: [https://www.instagram.com/p/CKWdOx6FczD/](https://www.instagram.com/p/CKWdOx6FczD/) * I recommend bringing your own material so you can keep practising at home after the classes. If you don't want to buy it, I can also lend it to you for a small extra fee of 5€. Please let me know in advance. ### **Booking by email only:** Email: **hola.berlinartclub@gmail.com** You’ll receive payment details and the exact address upon confirmation. 🎟️ **Spaces are limited—join us!** RSVP here does not save you a spot. www.lujancordaro.com [@lujancordaro](www.instagram.com/lujancordaro) [@berlin.art.club](www.instagram.com/berlin.art.club)

Kommt am 2. Montagabend im Monat ins Offene Wohnzimmer zum Open Draw! Raucht Euch auch manchmal der Kopf von zu viel PC-Arbeit? Der Asphalt der Stadt ist heute wieder viel zu grau? Ihr würdet am liebsten mal wieder wild auf einem Blatt Papier rumklecksen oder gedankenverlorene Linien zeichnen? Höchste Zeit zur Tat zu schreiten! Wir wollen in entspannter Atmosphäre die kreativen Zellen auf Volldampf fahren und uns der Inspiration überlassen. Mit Musik im Hintergrund sowie Wein, Tee und Snacks im Repertoire wird dann gekleckst, gemalt, gezeichnet, geklebt, geredet und gelacht. Das Ganze kann sehr ambitioniert stattfinden, aber genauso zum Hirn-abschalten dienen. Austausch, Bilderswapping und gegenseitige Tipps/Kritik sind sehr willkommen. Material stellen wir (Kreide, Bleistift, Wasserfarbe, Acrylfarbe, Pastellstifte, Kohle, Papierbögen, Spiegel, Postkarten, Zeichenbücher, Illustrierte). Sujet kann alles sein: Der/die Tischnächste, der letzte Traum, oder der Feldhase Dürers. Technik auch: Von (Selbst)portrait über Stilleben bis zur Comiczeichnung soll alles abgedeckt werden. Wir bieten jeden 2. Montag im Monat offene Treffen zum kreativen Arbeiten sowie gelegentlich technik- und themenbasierte Workshops an. Wie immer wird um eine Spende für Raummiete/Material von 5-10€ gebeten. Anmeldung: Katharinav.runnen@gmx.de

Andere drücken die Schulbank, wir aber wollen in gemütlicher (und realer) Atmosphäre wieder aufeinandertreffen und einen Deutsch-Spanisch-Tandemkurs aufleben lassen. Beim einfachen Zusammenkommen und kennenlernen lässt es sich schließlich viel effektiver lernen. und Spaß haben. ...

AI is changing the way we build software. Agentic Software Engineering takes this a step further. Rather than using AI only for isolated tasks, teams work with specialized AI agents that take on concrete responsibilities across the software lifecycle, from planning and coding to testing and documentation. These agents operate in clearly defined roles and are coordinated through structured workflows. Developers set the goals and guardrails, guide how the agents are used, and review the outcomes. The result is a new kind of collaboration between humans and machines, with a stronger focus on quality, speed, and scalability. The first Agentic Software Engineering Night Berlin will take place on **April 14, 2026**. Join us for two talks by **Torben Keller** and **Johannes Rave**, plus plenty of time for discussion and networking. **Agenda:** 18:30 Open Doors 19:00 **From Vibe Coder to Code Owner** – Torben Keller An AI agent can generate thousands of lines of code in a few minutes. That's powerful – and overwhelming. You can't read and fully understand every line anymore when you want to take advantage of agents. But if you're shipping to production, you own that code. So, how do you take responsibility for something you didn't write and can't fully review? This isn't a new problem. Developers working on brownfield projects face it every day. You join a team and inherit a codebase with hundreds of thousands of lines written by people who left years ago. You don't know every line – yet you ship features, fix bugs, and take ownership. But how? The same principles apply to AI-generated code. What we've learned from decades of working with legacy systems and inherited codebases translates directly to the age of vibe coding. In this talk, you'll learn: * What brownfield development teaches us about owning code we didn't write * How to build an "Agent Harness" that integrates these practices into your AI workflow, ensuring agents follow your rules and standards **About Torben:** *Torben is a consultant at INNOQ, where he focuses on how software teams can work effectively with AI agents. His main area of expertise is the shift from traditional coding to Agentic Software Engineering, in which developers orchestrate multiple AI agents to carry out autonomous tasks across the development process. He also teaches INNOQ’s three-day [Agentic Software Engineering training](https://www.innoq.com/en/topics/agentic-software-engineering-training/) and regularly speaks at conferences and meetups, where he shares practical insights and proven strategies for introducing agentic development approaches.* 19:45 Break 20:00 – **No Constrain, No Gain: Structure for the Agent, Clarity for the Human, Flexibility for the Business** – Johannes Rave AI coding agents are remarkably good at producing code. Whether that code reflects what the business actually needs — and whether it still makes sense to work with six months later — is a rather different question. The temptation is to treat this as a prompting problem — give the agent more context, better instructions, clearer goals. An overlooked lever is paying attention to architecture. When domain logic has its own clearly bounded home, separated from the technical plumbing around it, something interesting happens: the agent stays focused, the human can actually review what matters, and the whole thing remains open to change without requiring a rewrite. This talk shares one approach to getting there — and how some well-placed constraints might set you free. **About Johannes:** *Johannes Rave is a Senior Consultant at INNOQ. He develops LLM-first applications and high-performance web services. He connects design and usability with scalable architecture and operations. Before tech: industrial design, automotive modeling, and running a nightclub.* 20:45 Open End

Do you want to start building AI agents, but never had a chance to start? Are you an experienced agent builder and you want to test your skills in a fun environment? Are you a non-technical person who wants to get a taste of building AI agents? Are you an AI agent? Then come and let’s have some fun. **Format** We will have an AI agent competition. We will build agents and let them compete in how fast they can escape from a dungeon with challenges! Never built agents before? Don't worry, we'll provide a template of an agent. Not a technical person? Don't worry, we'll provide a visual agent builder (you can build agents from your smartphone) There will be 2 leagues: * Beginners: no skills of agent building or software engineering needed - you will only need a smartphone. * Advanced: bring your laptop with your favorite agent development tools **Prerequisites**: * **a Google account** (to sign in into the competition platform) * **readiness to spend ca. 5-10 EUR on OpenRouter API credits** (unless you already have a subscription to some LLM provider allowing API usage) * **(optional) laptop with your preferred development environment for building agents** (alternatively you can use a web-based agent builder from your smartphone, but it only allows relatively simple agent configurations)

Chitta Walks is for people whose days move fast, while the mind never fully lands. Thoughts keep looping even when nothing is urgent. The body moves, but attention is elsewhere. Over time, this disconnect drains clarity and ease. This walk is a simple reset. We meet in Berlin’s Tiergarten and walk at a gentle pace. Parts of the walk are in silence, with light guidance and a few short prompts. The walk itself is the practice, bringing body and mind back into the same moment. No apps. No performance. Just a clear space to slow down and notice what is happening. If you want to slow down without withdrawing from life, join a Chitta Walk. ✨ **What to expect (approx. 90 minutes):** * A short arrival and orientation * A guided silent walk (phones off, no conversation) * One concise science-based impulse on attention or stress * Optional reflection in pairs or small groups * A simple takeaway or experiment for daily life 🚶**Who this is for:** * Professionals, creatives, and people in transition. * People who feel mentally busy and want more clarity and balance. * Those curious about mindfulness, but grounded and practical. * Anyone comfortable with silence and gentle self observation. 🔔 **Practical notes:** * Duration: 60-90 minutes * Wear comfortable shoes and weather-appropriate clothing * No prior experience needed * Group size is limited to keep the space quiet and focused 🧭 **Facilitator:** My name is Partha Sarathi, you can call me PS. I have lived in Berlin for over 12 years. With a background in physics and materials science, my interest in mindfulness grew through personal experience with stress and health challenges. I facilitate the space and structure of the walk, inviting shared exploration rather than instruction. 🤔 **Why Chitta Walks?** Chitta is a Sanskrit word referring to the mind or field of awareness, used here in a practical, non-religious sense. Chitta Walks is about noticing how the mind works by slowing down and walking together. Mindful walking makes thought patterns visible in real time, while moving and sensing in the world. The name points to a simple capacity: noticing what is happening in the mind without immediately trying to fix, judge, or optimize it. 🌿 **Possible effects:** A calmer nervous system. Clearer attention. A felt sense of being more present in your body. Subtle insights into how your mind reacts under everyday conditions. A quieter, more grounded way of moving through the city. **Come as you are. Walk. Notice. Leave with a little more space inside.**

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. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD

Curious about “vibe coding” but not sure what it actually means? This beginner-friendly talk is about how people are using AI to build websites, apps, automations, and small software projects by describing what they want in plain English. We’ll cover what vibe coding is, what AI is good at, where it falls short, and how to actually use it without getting lost. The goal is not to hype AI as magic — it’s to show how to use it as a practical tool. This session is designed for beginners, curious builders, non-programmers, and developers who want a clearer picture of how to build with AI today. Topics include: * What “vibe coding” means * What AI can help you build * Where AI is useful and where it is unreliable * A simple workflow for building with AI * Prompting tips for better results * Common beginner mistakes to avoid If you’ve ever thought, “I have an idea, but I don’t know how to build it,” this talk is for you. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
