[English version below] Cześć, Mam ogromną przyjemność zaprosić Was na pierwsze spotkanie organizowane wspólnie z łódzkim oddziałem **EPAM**. W planach dwie prezetacje odnośnie AI: **Java RAG: Build Your Own Black Box** oraz **Spring AI**. **Ważna uwaga: spotkanie wyjątkowo zaczyna się o 17:30!** Hi, I’m very happy to invite you to our first meetup, which is being organized in collaboration with the Łódź branch of EPAM. We have two AI-related talks planned: **Java RAG: Build Your Own Black Box** and **Spring AI**. **Important note:** this meetup will **start at 17:30**. **Spring AI** Transforming your existing Java applications into intelligent, AI-driven systems no longer requires a PhD in Data Science or switching to Python. In this session, we explore how Spring AI brings the familiar power of the Spring ecosystem - portability, modularity, and POJO-based design - directly into the world of Artificial Intelligence. We’ll move beyond basic API calls to show how you can harness Large Language Models (LLMs) like OpenAI and Google Gemini using the same @Service and dependency injection patterns you use every day. We will provide an overview of the major capabilities and also dive into the latest Spring AI v2 milestones that position Java at the forefront of the agentic AI wave. By the end of this talk, you’ll see how Spring AI acts as a bridge that allows Java developers to build production-ready, intelligent features without reinventing the wheel. **Dzmitry Sidarenka** Dzmitry has nearly 20 years of experience specializing in systems built with Java. He is passionate about building and testing robust APIs and is known for thriving in high-pressure production incident troubleshooting. His work focuses on designing reliable, maintainable services and improving system resilience through pragmatic engineering practices. **Java RAG: Build Your Own Black Box** Retrieval-Augmented Generation (RAG) often feels like a magical black box. But once you start experimenting with it yourself, it quickly becomes clear how powerful the combination of information retrieval and generative AI can be. Key topics: \- What is Retrieval\-Augmented Generation \(RAG\)? \- Why should you consider using it in your own projects? \- Key RAG components and how the workflow operates \- How to build your own RAG solution using Java \- Live demo of a Java\-based RAG project and ways to extend and improve it **Ahmed Samy** Ahmed is a Senior Software Engineer at EPAM Systems. As he jokes, he often feels like a junior at work - mostly thanks to his constant curiosity and desire to keep learning new things. In his daily work, he actively uses AI as a learning companion, exploring new ideas by experimenting, testing different approaches, and working with various pieces of code. **About the partner** EPAM is a global leader in AI transformation engineering and integrated consulting, serving Forbes Global 2000 companies and ambitious startups. With over thirty years of expertise in custom software, product and platform engineering, EPAM empowers organizations to become AI-native enterprises, driving measurable value from innovation and digital investments.

[Beads](https://github.com/steveyegge/beads) is a rising Go project that brings structured planning to any workflow, whether agentic or hands-on. [Akim Zmerli](https://www.linkedin.com/in/akimzmerli/) will present his favorite techniques, TUI projects and what Rob Pike thinks about the current state of affairs. The beads project is less than six months old (2025-10-11), but already well beyond 250 KLOC, with more than 200 KLOC written in Go. We are always interested in developer tools. At [#44](https://golangleipzig.space/posts/meetup-44-wrapup/), less than two years ago, not a single AI coding tool did make it to [our list](https://golangleipzig.space/posts/meetup-44-wrapup/). Looking forward to this foray into the agentic coding space. ### Schedule * 18:45 Doors open * 19:00 Welcome * 19:10 Beads * 19:45 Open discussion We’ll meet: * in person at [Basislager Leipzig](https://basislager.co), at [Peterssteinweg 14, 04107 Leipzig](https://maps.app.goo.gl/1fMkeDSPZ7Aauszh8) ([OSM](https://www.openstreetmap.org/node/3504864558)) * and online via [Jitsi](https://meet.jit.si/LeipzigGophers58) Join us to discuss SOTA dev tools and more.

Join us as we get together for an Arthouse Movie Friday event to see the A24 dark comedy /romance / psychological-thriller, THE DRAMA! The film stars Zendaya and Robert Pattinson as a happily engaged couple whose relationship is challenged when one discovers unsettling truths about the other. Here are details, a trailer and our plan for this event: DESCRIPTION: The film follows a happily engaged couple whose relationship is put to the test when an unexpected turn sends their wedding week off the rails. The film comes from A24, is written/directed by Kristoffer Borgli stars Zendaya, Robert Pattinson, Mamoudou Athie, Alana Haim, Hailey Gates and Zoë Winters. QUICK WORD OF WARNING: The film hasn’t screened for critics yet and most of the details are being kept tightly under wraps. But, early buzz (possibly promotional) says the film is a brilliant psychological thriller/romance but also provocative, twisty and some contains occasional uncomfortable viewing! I love the cast and trailer, so look forward to seeing for ourselves! ZENDAYA-PATTINSON TRIFECTA CHALLENGE: Robert Pattinson and Zendaya will star in THREE movies together this year, including THE DRAMA, Christopher Nolan’s THE ODYSSEY this Summer and Denis Villeneuve’s DUNE: PART THREE at Christmas! TRAILER: [https://www.youtube.com/watch?v=6zmKcUa4Xxk](https://www.youtube.com/watch?v=6zmKcUa4Xxk) PLAN: We’ll plan for 7pm-ish showing and will meet in the lobby area about 30 minutes before showtime! Advance ticket purchase not required for this theater but early arrival is advised. Possibly post-movie get-together at the nearby Rusty Bucket! Complete details will be confirmed/announced as the date gets closer. Take care and look forward to seeing you there, Dan

Join us as we get together for a Discount Tuesday / Choose Your Movie event to see your choice of two great films! Option 1 is the dark comedy/drama based on a true story TOW! The film stars Rose Byrne as a homeless Seattle woman how battles a towing company. Option 2 is the off-the-rails, over-the-top, action-comedy-horror THEY WILL KILL YOU! The film stars Zazie Beetz as a woman who answers a help wanted ad to be a housekeeper in a mysterious New York City high-rise not knowing its mysterious past! Here are details, trailers and our plan for this event: TOW: This dark comedy/drama is based on a true story and follows a homeless Seattle woman who fights her way out of "tow-company hell" to reclaim the car that had held her life together after receiving a tow bill for $21,634. The film stars Rose Byrne, Ariana DeBose, Demi Lovato, Octavia Spencer, Dominic Sessa, Elsie Fisher and Simon Rex! The film premiered to solid reviews at last year’s Tribeca Film Festival where critics declared, “TOW is a winner!” It’s “a story of perseverance, heart, and real fight, the kind of small human story we see less frequently these days, but need now more than ever.” TRAILER: https://www.youtube.com/watch?v=qdkpcsuPAhA THEY WILL KILL YOU: A woman takes a job as a housekeeper in a NYC high-rise, unaware of the building's history of disappearances. She soon realizes the community is shrouded in mystery. The film is directed by Kirill Sokolov and Zadie Beetz, Myha'la, Paterson Joseph, Tom Felton, Heather Graham, and Patricia Arquette. The film is being released immediately following its premiere at this year’s SXSW Festival earlier this month. Early reviews say it’s “an adrenaline rush of action-packed fights, tons of blood and gore and plenty of laugh-out-loud moments” and a movie that’s “unafraid to march to its own campy, violent, and clever little drummer!” TRAILER: https://www.youtube.com/watch?v=XYqQPiXpi4w PLAN: Not exactly a “Choose Your Movie” event, more like an early show and a late one (or both if you’re feeling sparky)! \* If you’d like to see TOW, please purchase your ticket for the 5:00pm showing and meet in the upstairs lobby between 4:40 and 4:50pm! \* If you plan to see THEY WILL KILL YOU, please purchase your ticket for the 7:45pm showing and meet in the upstairs lobby between 7:25 and 7:35pm! \* Tickets for both films on sale now and advance purchase is advised! Tickets just $5.00 ($6.50 after online fees when purchased via the GFC website). Once you have yours, please list your movie of choice and seat number in the Comments section of this event. \* Also, as a reminder, close, convenient parking available in the nearby garage (Between 9th and 11th, just off High) and just $2 when you have your ticket validated at the theater! Look forward to seeing you there, Dan
