Please scroll down for English! Egy belső utazásra hívlak a hangok szárnyán kéthetente pénteken. Sólepte burokba. Hanghullámzásba. Befelé fordulásra. Amíg tested egy dönthető széken megpihen, lényed a hanghullámok mossák át. A só behatol a bőröd alá, lágyan tisztítva át a finomenergetikai rendszered. A hangrezgések nyitnak, töltenek, emlékeztetnek. Hullámaik áttörik, felszabadítják a belső energetikai elakadásokat. Megtámogatják, hogy a belső egyensúly helyreálljon. Visszavezetnek az áramlásba. Egy olyan térbe hívlak, ahol test és elme megpihen, a szem lecsukódik és nyílik a szív. 60 percnyi időtlen utazásra önmagadba. Egy csendes kapcsolódásra, magaddal létre.

While your body rests on a reclining chair, your being is washed by sound waves. The salt penetrates under your skin, gently cleansing your subtle energy system. The sound vibrations open, fill, remind. Their waves break through, releasing internal energetic blockages. They support you to restore your inner balance. They lead you back into the flow. I invite you to a space where body and mind rest, eyes close and heart open. For a 60-minute timeless journey into yourself. For a silent connection, to create with yourself.

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.

Enjoy your time learning and practicing public speaking with Budapest Toastmasters! There is no need to speak or any previous experience in Public Speaking. --- 👉Keycode: 12, 3rd Floor. Please arrive by 6:20 PM, the meeting starts at 6:30 PM👉No registration or dress code is needed, the event is FREE.👉NOTE: We will have signs in the place so you can locate easily the Toastmasters Meeting room. --- Toastmasters International is a world leader in communication and leadership development. 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.

**This week's venue: Beer People \| Lázár utca 7\, Budapest 1065** We hold a bi-weekly workshop to encourage creative writing where we share pieces of creative writing and solicit feedback from the other attendees. Some members also use the forum to find others with whom to collaborate, edit work, and/or brainstorm plot, themes, settings, and so forth. And from time to time, we participate in competitions, recite and/or offer material for events organized by other groups. At the moment there is no prompt for this particular meetup. Instead, writers are invited to submit something they have (or are working on) or to craft a short story specifically for the event. Of course, there's no pressure to submit something. Many participants are interested in hearing ideas, questioning the authors, and examining style and technique. Often, we explore other published works as well. The submission guidelines are as follows: 1. limit the piece to 850 words (to give enough time for any other submissions being read at the event); 2. make the text available (though you can read it aloud) for the other attendees. Many authors bring a few printed copies, others post their work in the comments of the meetup; 3. have a question in mind for the group about the submission; and, 4. If offering something from a longer work, be prepared to give a little bit of background first.

**Hey fellow AWS enthusiasts! ✨** May is all about AWS Partnership! Not a usual topic you hear about at User Groups. So we are more than thrilled to hear about **Deepika Tomar**'s journey as the AWS Cloud Lead at HWS Gruppe on pathing the way for her company to become an AWS Advanced Partner. Thanks to our friends at **[codecentric Nürnberg](https://www.codecentric.de/standorte/nuernberg)** for sponsoring the event with food and drinks and opening their wonderful offices for us! **📆 Tonight's Agenda** 19:00 - Welcoming **19:15 - Talk by Deepika** 20:00 - Food, Drinks & Networking Looking forward to seeing you 👋🏻 [Nora](https://www.linkedin.com/in/nora-schoener/) & [Frank](https://www.linkedin.com/in/frankprechtel/) \-\-\- The talk ⤵️ **From AWS Registered to Advanced Tier in 2 Years: Practical Lessons from the Field** In this session, I will share how we progressed from AWS Registered Partner to Advanced Tier within two years, focusing on real-world actions that made the difference.

Join us for a special edition of the Android Budapest meetup in May! This time, we’re collaborating with mDevCamp, the Prague-based mobile dev conference. You will have an opportunity to get a free ticket to the conference! Before the summer break, you’ll have another opportunity to learn more about Android and meet fellow mobile devs! We’ll have two great talks to set the tone of the evening - this time you’ll hear from two organizers of our meetup, on the topics of Kotlin Multiplatform and screen recording on Android. **📜 Schedule:** **18:00 - 18:30: Gathering and socializing** **18:30 - 19:15: First talk** **19:15 - 19:45: Break** **19:45 - 20:15: Second talk** **20:05 - : More socializing!** **—** **🔷 Going Multiplatform with Your Android App - Márton Braun, JetBrains** Existing Android apps are in a great position to expand into Kotlin Multiplatform: you might already be using patterns, libraries, and APIs that work on more platforms than just Android. With Compose Multiplatform, you can build an app with a fully shared Kotlin codebase, targeting iOS, desktop, and even the web! In this talk, we’ll look at how you can migrate an existing Android app to multiplatform. As this can be a significant engineering effort for an existing, well-established app, we’ll also discuss how to plan and organize the required changes, and how to adopt KMP incrementally across your codebase without disrupting day-to-day development. **🔷 When MediaProjection Isn't Enough - Building a Custom In-App Session Recorder - István Juhos, Spoke** Debugging user issues gets so much easier when you can see exactly what they experienced. While off-the-shelf solutions exist to integrate screen recording into our apps, they didn't give us the quality, flexibility, or control we needed. So, our team built our own native, in-app session recording tool for Android. In this talk, I'll share why we decided to go in-house, how we tackled the technical and UX hurdles along the way, and what we learned about recording high-quality video and audio data. We'll dive into tricky bits like exploring - and discarding - the MediaProjection API, handling codecs and muxers across devices, designing recording controls that stay out of the user's way, playing back recordings, and managing background uploads without draining your users' battery or patience. — 🏢🍴 Thanks to [Supercharge](https://supercharge.io/careers) for hosting us in their lovely office, and the organizers of [mDevCamp](https://mdevcamp.eu) for the food and the drinks! 🚪 Doors open at 18:00 and the first talk starts at 18:30! 🗓️ The event is free but requires registration, so please RSVP here and don’t forget to update your response if it changes! 📸 We plan to take photos, so if you would not like to appear on them, please tell one of the organizers! **🎤 We are always looking for new presenters, so if you have an idea for a talk, please reach out to us at meetup@androidbudapest.com or submit at [https://androidbudapest.com/talkidea](https://androidbudapest.com/talkidea)!**

Agilitás és beszélgetés és sör és fröccs. Vagy limonádé, kinek mi. Gyertek egy kötetlen találkozóra, ahol ha hozol egy elakadást, vagy ügyet, talán még beszélünk is róla, és segítünk továbblendülni. De ha nem, az is oké. Az asztal MASZK néven lesz, ha nem találsz minket.

Many organizations treat the Product Owner as a backlog administrator, ticket writer, or go-between — and then wonder why their products drift, stall, or miss the mark. The role gets distorted in predictable ways, and the cost is real: slower decisions, misaligned teams, and products that serve processes instead of users. In this session, led by [Tom Molnár](https://www.linkedin.com/in/tamas-molnar-57902919/) we'll unpack the **6 misunderstood PO stances** — the anti-patterns that quietly erode value — and contrast them with the **6 effective stances** that make a Product Owner truly impactful. **What we'll cover:** ❌ **Misunderstood stances (anti-patterns):** * **Clerk** — just adds everything to the backlog, no vision or decisions * **Story Writer** — focuses only on writing user stories * **Project Manager** — focuses on deadlines and output instead of value * **Manager** — manages people instead of the product * **Subject Matter Expert** — gets lost in detailed expertise * **Gatekeeper** — becomes a bottleneck; everything goes through them These aren't value-creating behaviors — they're distortions of the role. ✅ **Effective stances:** * **Visionary** — defines a clear product vision and goals; focuses on the future * **Collaborator** — actively works with the team and stakeholders * **Customer Representative** — brings in user needs; explains the "why" * **Decision Maker** — makes fast decisions → faster time-to-market * **Experimenter** — thinks in hypotheses; validates instead of assuming * **Influencer** — creates alignment across the organization A good PO isn't just one of these — it's a combination of all. 🎯 **Key takeaway:** According to Scrum, the PO's goal is to maximize value. Many organizations misunderstand this. The goal is to recognize when you slip into a bad stance and shift back. **Who should attend:** Product Owners, Scrum Masters, agile coaches, engineering leads, and anyone working with or alongside POs who wants to raise the bar on how the role is understood and practiced. -- An in person, English speaking session. No video feed will be provided. Please note, that we dont have catering for the event.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

Join us for a practical, beginner-friendly guide to choosing the right large language model. We’ll compare major models like ChatGPT, Claude, Gemini, and Llama, talk about when to use hosted APIs versus local models, and break down the tradeoffs around cost, speed, quality, privacy, context windows, coding ability, and reliability. You’ll leave with a clearer mental model for picking an LLM based on your actual use case instead of hype, benchmarks, or brand names. No deep AI background required. 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.
