Register: https://www.eventbrite.de/e/build-smarter-ai-graphrag-generative-ai-workshop-tickets-1985345958205 Join us for a hands-on introduction to Generative AI with Neo4j at 42 Berlin. **Large language models are powerful — but without structure, they lose context fast.** **As part of the mAI ist für AI series at 42 Berlin, this workshop explores how [Neo4j](https://neo4j.com/ "https://neo4j.com/") can improve GenAI applications and reduce common challenges such as hallucinations.** In this instructor-led workshop, participants will explore how graph databases can improve GenAI applications and reduce common challenges such as hallucinations. You’ll learn key concepts including Large Language Models (LLMs), Retrieval-Augmented Generation (RAG), GraphRAG, vector search, knowledge graphs, and AI agents. The workshop follows a **mixed format, combining short theoretical inputs with practical exercises**. Participants will work through tasks while instructors are available to support and answer questions.

Let’s be honest: the traditional cultural sector often forces us to choose between our creative integrity and our financial survival. The myth of the "starving artist" or the "solitary genius" is a trap that keeps cultural workers in a constant state of precarity. But what if we could design our projects differently? What if we could build cultural businesses based on solidarity, cooperation, and radical sustainability? Join us on May 27th for an interactive, hands-on workshop co-hosted by ODBK and Travelling U. We will explore how to dismantle extractivist practices and design alternative business models that actually serve the creators. **What you will learn in this session:** * Beyond the Canvas: How to view system design and business models as part of your artistic medium. * Alternative Frameworks: An introduction to cooperative structures and the solidarity economy. * Redefining Value: How to measure the success of your cultural project using metrics of care, rather than just capitalist extraction. * Real-World Pathways: Tangible examples of cultural workers who have successfully subverted the system to gain economic sovereignty. **Who is this for?** Artists, cultural managers, creative freelancers, and social entrepreneurs in Berlin who are tired of the traditional hustle culture and want to explore sustainable, collective ways to structure their work. **About the Facilitator:** Oihane Amurrio is an artist, educator, and cultural entrepreneur based in Berlin. She specialises in designing alternative pedagogical models in the cultural sector and is the lead designer of the *Cooperative Cultural Entrepreneurship (CCE)* program at Travelling U.

**Move Capital. Move Talent. Move Africa.** Africa is the youngest continent on earth. By 2050, 1 in 5 people globally will be African. Yet African startups still receive less than 1% of global VC funding. What is the real problem? Is it time to tap into the estimated $95–100 billion USD in remittances sent by the diaspora? This Africa Day, in partnership with the Westerwelle Foundation, which has just published The German–Africa Investment Report, we will go deep into the gaps to explore : 📈 How Africa’s startup ecosystem is growing 🌍 Which New markets are rising, and how to pay attention to them 💡 Which segments pose the greatest returns outside of FinTech 🤝 How to take the best next step as an investor, proven by research. The event welcomes: Founders, Investors, Operators, the diaspora, and Institutional partners looking to make their moves into the African Market with intention. To our network members and partners who have been looking to make the move from remittances → to investment, from fragmented effort → to ecosystem building. This event is for you. Culminating from this event will be our delegation trip to #Nigeria and #Ghana in September in Collaboration with GITEX Nigeria and South Africa, and Namibia in November. Move Africa. #AfricaDay #AfricaRising #AfricanDiaspora #InvestInAfrica #AfricanInnovation #investment #funding # VC #Angelinvesting #African Excellence #Excellence #Leadership #FutureOfAfricaEvening Programme **SCHEDULE** 18:30 Arrival Networking reception Guests arrive. No job titles on badges — just names and country of origin. The room begins to know itself before the panel starts. 19:00 Opening Welcome & the diagnosis — 10 mins The host frames the evening in plain language. Not a speech — a provocation. Four sentences stating the diagnosis. Then the panel takes the stage. 19:10 Panel · 50 mins The conversation — moderated, flowing, unscripted Four panellists. One moderator. The conversation moves through the diagnosis naturally — from the wealth gap, to the talent drain, to the trust deficit, to the intention trap. No fixed questions. The moderator's job is to keep the room honest and the conversation moving toward one inevitable question: so what do we do about it tonight? 20:00 Panel · Open floor The room joins the conversation — 20 mins Not a Q&A. The moderator selects three or four people in the room — pre-identified — to add their perspective. Brief, pointed contributions that deepen the diagnosis rather than repeat it. The panel responds. The room feels heard. 20:20 Break Drinks — 20 mins The panel comes off stage and into the room. Guests speak directly with panellists. The conversation continues informally — which means it deepens.

While we are approaching the middle of the year and KotlinConf is just over - we are thrilled that Trade Republic hosts us again! So mark the date! **Line-Up:** 👉 **Lists, Sequences, and Flows: Scaling Data Processing in Kotlin without Melting Your Memory.** *by Daniela Valero* In this talk, Daniela shares her journey of meeting a major backend deadline while managing a data pipeline's memory footprint. You’ll learn how to transition from eager List operations to lazy Kotlin Sequences and jOOQ Streams (using database fetchSize chunking) to keep memory usage flat. Finally, we’ll explore using Kotlin Coroutines and Flow to introduce safe concurrency so your data processes quickly without straining your database. 👉 **The show must go on** Kotlin-based Kafka dead-lettering solution without external (system) dependencies *by Blagoja "Baki" Stamatovski* **👉 Job Market Insights from a Kotlin developer** *by* Ivan Gafurov **Speaker Bios:** 🗣 **TDB**

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** Like it or not, AI agents are now capable of turning a quickly written paragraph of requirements into a pull request that is ready to be integrated into real-world production applications and it's now our responsibility to make sure AI doesn't go rogue and take down prod - or corrupt our data by misunderstanding the requirements or our existing schemas. In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** https://youtube.com/live/BltmWMH1zG0?feature=share
