Letting Go

[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: Go Open Source Projects in the Age of AI Hello, 世界! For meetup #58 on Tuesday [Mar 31, 2026 19:00 CET](https://www.meetup.com/leipzig-golang/events/312537698/) we are happy to have [Akim Zmerli](https://www.linkedin.com/in/akimzmerli/) give us an intro to [beads](https://github.com/steveyegge/beads), specifically: > How agents perform long-running tasks and pass context seamlessly to each other. [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.

The emotional pain from past bad experiences easily lingers in the present, making it hard to enjoy life and create your future. Even when you think you've moved on, the negative emotions can be triggered, sending you back into the pain of that experience. And we are talking about pain; emotions such as grief, depression, anxiety, fear (or terror), boiling anger, simmering resentment, feelings of shame, blaming and regret can leave you incapacitated to a greater or lesser degree. In this local event we will be discussing the reasons why these past bad experiences have the power to affect you long after they occurred. We'll go over why the emotional pain can be so strong. We'll also discuss some simple solutions to overcome your emotional pain and be free to fully enjoy your life again. Examples of painful experiences include: * A broken relationship or divorce. * Death or loss of a loved one. * Death of a pet. * A sudden shock or bad news. * A betrayal. * Being part of an abusive relationship. * A bad injustice. * Loss of a job, position or business. * A grave illness or injury. The negative emotions from these experiences don't just go away on their own. But the good news is there is a way to clear them out of your way. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is sponsored the Dianetics & Scientology Self-Improvement Center.

In this local meeting, you will discover knowledge that you can use to get over the past. The key to improving your personal motivation, self-confidence, and happiness is to get over your painful memories. When you become free of your past, you will be free from stress, anger, anxiety and depression. Studies show that negative emotions can affect your health. By being free of negative emotions, believe it or not, you will most likely even look younger, feel more energetic, and become healthier!

This is an in-person meeting. Did you know that unwanted emotions like loneliness, sadness, hopelessness, anger, fear, anxiety, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not chemical imbalance in your brain due to some nebulous chemical reactions by chance. Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. For instance, let's say you are already carrying a huge load on your back, then you cannot take on much more, but, let's say something else happens to you, such as the difficulties from the Pandemic, then the resultant combined weight on you can take you over the edge, kind of like the straw that break the camel's back. When this happens, people's attention usually goes to the straw that was added, but actually the majority of the weight had come from the huge load that were already there, holding a person down and causing a person issues. So how do you remove the huge load that was already there? How do you lighten them up? Is it possible to get rid of them? That is what this meeting will be all about. Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Dianetics and Scientology Life Improvement Center of Central Ohio.

Main Library, Meeting Room 2B Join us for a welcoming evening of reflection, gentle music, and meaningful conversation. We’ll begin with a short grounding moment, followed by a brief reading from spiritual or philosophical traditions, and an open reflection circle where participants can share (or simply listen). Libera Animae is an interfaith community focused on inner growth, creativity, and authentic connection. All backgrounds are welcome.

This is a free, in person meeting. Burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. We look forward to having you join us! This class is sponsored by the Dianetics & Scientology Life Improvement Center of Central Ohio.
