Our membership is 313,000 strong. Members improve their speaking and leadership skills by attending one of the 14,650 clubs in 126 countries that make up our global network of meeting locations. The world needs leaders. Leaders head families, coach teams, run businesses, and mentor others. These leaders must not only accomplish but must also communicate. By regularly giving speeches, gaining feedback, leading teams, and guiding others to achieve their goals in a supportive atmosphere, leaders emerge from the Toastmasters program. Every Toastmaster's journey begins with a single speech. During their journey, they learn to tell their stories. They listen and answer. They plan and lead. They give feedback—and accept it. Through our community of learners, they find their path to leadership.

El objetivo de este encuentro es romper el hielo, hablar de las historias que nos gusta escribir, de por qué escribimos, de los libros que nos gusta leer, de qué dificultades encontramos al enfrentarnos al folio en blanco y de qué esperamos del grupo. En definitiva, se trata de conocernos como personas para entendernos como escritores. No importa si has escrito diez novelas, cuatro cuentos o el precioso título de un poema sin versos. Aquí todo aspirante a juntaletras es bienvenido.

**(Magyar nyelvű alkalom)** Ma este arra bátorítunk, hogy hozz magaddal egy vagy több kérdést, ötletet, dilemmát vagy témát, amiről szívesen beszélgetnél. Kipróbáljuk őket: minden témára körülbelül 10–15 percet szánunk, mielőtt továbblépünk a következőre – kivéve, ha a beszélgetés annyira érdekes lesz, hogy nem akarjuk megszakítani. Néhány példa kérdés (az angol alkalomról): - A köz tragédiája - Létezhet-e objektív erkölcs? - Determinizmus vs szabad akarat - Ha beszélünk a különbségeinkről, az kevesebb, vagy több „izmust” eredményez? A cél nem az, hogy megnyerjünk egy vitát vagy közös álláspontra jussunk, hanem hogy gondolkodjunk, megkérdőjelezzük a feltételezéseinket, és olyan nézőpontokkal találkozzunk, amelyek különböznek a sajátunktól. Hozz egy kérdést. A többit mi intézzük.

Google Cloud Budapest Meetup is back! Join us on June 17th at the Aliz office in Budapest for an evening of deep-tech insights, practical engineering strategies, and networking with fellow Google Cloud and AI enthusiasts. As AI tools reshape the development landscape, the definition of a "good engineer" is shifting. This meetup isn't about generic AI prompts - it's about the concrete skills and old-school engineering discipline required to build reliable, scalable, AI-native applications. 🎫 The event is free, but seats are limited. **Save yours now! 👇** ⌛ Register here: [https://www.aliz.ai/en/event/google-cloud-budapest-meetup-2026](https://www.aliz.ai/en/event/google-cloud-budapest-meetup-2026) ================= **Talk 1** **Becoming a Context Engineering Professional in Your Domain** by Tamás Imets (AI Solution Architect), Aliz The most underrated skill in the AI era: context engineering. How to structure prompts, design context windows, and become a force multiplier in your technical domain. Practical patterns from the field that turn good engineers into AI-native practitioners. **Talk 2** **The Revenge of the Fundamentals: old-school ideas winning in the AI era** by Máté Czékus (Lead Architect) and Aamna Tayyab (Head of Delivery), Adroit Group The core argument: LLMs accelerate code generation are non-deterministic and inconsistent by default, which makes foundational engineering practices and tooling more important then ever. Teams that skipped the fundamentals, or was still hand rolling checks when AI arrived are paying for it at integration boundaries — it'll be way more harder to guide agent to write compliant and consistent code, and even harder to review the huge amount that was generated. Three fundamental tools doing more work than they get credit for: * JSON Schema — enforcing the contract between modules * TDD — writing the tests before the code * Linters and formatters — static governance that guides the shapeand correctness what the model sometimes misses even with context Máté brings a live demo: one real multi-cloud cost explorer example showing what AI tooling produces by default vs the disciplined version side by side. ================= 📣 Meet the speakers **Tamás Imets** An **AI Solution Architect** at **Aliz** who has been tinkering with tech since age 13 - moving from taking apart toys for robots to founding an AI startup where he led product and engineering. When he’s not building AI-native systems, you’ll find him backpacking through East Asian megacities, playing squash, or experimenting with new musical instruments. **Máté Czékus** He is a **software engineer** at **Adroit Group** who spends his days planning, testing, and refactoring systems while exploring the latest technologies. A passionate specialty coffee enthusiast and functional programming nerd, he believes that if you can build something, you should also be able to deploy and maintain it. **Aamna Tayyab** As **Head of Delivery** at **Adroit Group**, Aamna works at the intersection of product and engineering analyzing requirements, shaping architecture, and turning ambiguous ideas into work teams can actually deliver. Alongside her job, she co-organizes GDG Budapest and stays active in the Google developer community. ================= ☁️ Exclusive Google Cloud meetup in Budapest. 🍕 Cool presentations from experts and a networking opportunity - drink and snacks are on us. 🏎️ Free guarded parking. 🐶 Dog-friendly venue. ⌚️ Arrival from 18:30, presentation starts at 19:00. 🎫 Free, limited seats event, ensure yours by registering: https://www.aliz.ai/en/event/google-cloud-budapest-meetup-2026

Improving the quality of our breathing can powerfully support our lives. Practicing in the Salt Cave, with the support of 8 tons of salt, is a truly special experience. Everyone knows that during a cold or flu, salt can provide quick support. And of course, we all know how to breathe, because we are alive. Learning proper breathing takes time and a little perseverance. Even one breathing therapy session can bring us a lot of understanding, but for more reliable results, a greater number of repetitions is helpful. What can you expect at such a breathing therapy class in the Salt Cave? After settling into a comfortable seated position, we will go over the basics of proper breathing together, then step by step we will practice these gentle and slow movements with every breath. We warmly welcome you.

Practice Buddhist meditation in the middle of Budapest! The meditation is suitable for beginners. Each regular meditation is guided and begins with a short introduction. (all together is about 30-40 minutes) Our regular Buddhist meditations have proven popular with people who want to integrate authentic Buddhist methods into their daily lives. For the modern lay person who is juggling work, relationships, and an active role in society, we teach a meditation that is easy to learn, and profound and powerful for experienced practitioners. The meditation originates from the Karma Kagyu tradition of Tibetan Buddhism. It has a cumulative effect on mind, leading to greater clarity and calmness. Fearlessness, joy, and active compassion are the result of regular practice of Buddhist meditation. * Do I need any special clothing? No special clothing needed. * Does the attendance cost anything? No, the meditation is free.

Most people still use AI like a search box: type one question, get one answer, repeat. But the next step is AI agents: systems that can take a goal, break it into steps, use tools, remember context, and produce useful work for a human to review. In this beginner-friendly session, we’ll demystify what AI agents actually are — without hype or jargon. We’ll walk through practical examples of how agents can help with research, planning, writing, coding, operations, and personal productivity. We’ll cover: * What makes an AI “agent” instead of just a chatbot * How agents break tasks into steps * Where agents are genuinely useful today * Where they fail, hallucinate, or need human review * How to design simple AI workflows for your own work * A live demo of an AI agent-style workflow from start to finish No coding experience required. This is for anyone who wants to understand where AI tools are going and how to use them more effectively right now. 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.
