Apache Spark has become one of the most popular frameworks for large-scale data processing, thanks to its speed, simplicity, and flexibility. In this session, we will introduce Spark’s core concepts, explore the differences between RDD, DataFrame, and Dataset, and demonstrate how Spark can simplify complex data analytics tasks. Whether you are entirely new to Spark or looking to strengthen your big data skills, this talk will give you a clear and practical jump start into the world of distributed data processing. During this session, we are going to use the Scala programming language.

This meetup is free, online, and it will be delivered in English. The schedule is:
11:00–11:15 - Gathering
11:15–11:45 - Talk
11:45–12:00 - Q&A

Join us as we explore the upcoming Java 25 feature defined in JEP 502 — Stable Values. This new capability enables developers to defer initialization of immutable data while still allowing the JVM to treat that data as constant (and apply constant-folding and other optimizations). In this meetup, we’ll dig into the motivation behind stable values, how they bridge the gap between lazy initialization and performance-tuned immutability, show code examples, discuss use-cases (such as caches, pools, services), and what this means for modern Java architecture and startup performance. Bring your questions, and let’s dive into deferred immutability together! This meetup will be delivered in English.

Join us for a hands-on introduction to one of JavaScript’s most exciting upgrades: the new ES2025 Iterator Helpers API. We’ll explore how generators now support a rich, array-like functional toolbox - including `map`, `filter`, `take`, `flatMap`, and more — enabling clean, lazy, and expressive data pipelines without external libraries. Expect live demos, practical examples, and plenty of time for questions. Perfect for JavaScript developers of all levels looking to level up their modern JS skills.

Whether you are a seasoned developer or just starting your journey in tech, this event is a great way to expand your knowledge and gain valuable insights into the dynamic world of Open Source. Don't miss out on this exciting opportunity to be a part of the life michael community and explore the limitless possibilities of Open Source technology!

AI agents are no longer experimental curiosities. They are becoming a practical architectural building block in modern software systems. In this meetup, we will explore how to design, implement, and orchestrate AI agents using the OpenAI SDK, with a clear focus on real-world developer workflows.

The session will move beyond basic API calls and cover agent-oriented concepts, including tool usage, multi-step reasoning, state management, and coordination between agents and external systems.

You will see how agents can be structured to perform autonomous tasks while still operating within well-defined boundaries and developer control.

Through concrete examples and live demonstrations, we will examine common design patterns for agent-based applications, discuss where agents add genuine value, and highlight typical pitfalls to avoid.

This meetup is aimed at experienced software developers and architects who want to move from “prompting models” to engineering robust, production-ready AI agents. Attendees will leave with a clear mental model, actionable patterns, and the confidence to start building agent-powered systems using the OpenAI SDK.
