DubJUG 265, our live in-person event, presents Professor Ž (aka Željko Kozina!) Hear why Netflix dumped REST in favour of GraphQL and explore how memory management improves performance, the different parts of Java memory and the various garbage collectors. OFFICIAL BOOKING >>>>> https://ti.to/dublin-java-user-group/265-zeljko-kozina ## **Talk 1:** Netflix dropped REST, but should you? Last year, Netflix announced that it was dropping REST completely in favour of GraphQL. It is undoubtedly one of the popular kids on the Development playground right now. GraphQL is a new way to build APIs, one that's easier, faster, better, and more flexible than the old RESTful API system, or at least that's the promise. In this session, a REST developers' Assessment of Spring GraphQL, Željko will cover the basics of Spring GraphQL, explore its strengths and weaknesses, and determine whether it is a better option for your company than a conventional REST API. ## **Talk 2:** Trash Talk - Optimising Java Garbage Collection Understanding how Java organises memory is important for every Java professional, but this particular topic is a common knowledge gap for many software professionals. With the help of Željko, this talk explores how memory management can help you improve performance effectively, helping you understand the different parts of Java memory and the various garbage collectors so you can select your preferred one.

Hi all, Our first Meetup will be a casual get-together for anyone interested in Time Series Analytics, Forecasting, and Data Analytics. The idea is simple: meet new people, share your background, talk about your work/study experience, exchange ideas, and enjoy a coffee or a beer together in a relaxed atmosphere. We’ll meet at the bar on the ground floor of the Camden Court Hotel Camden Street Lower, Saint Kevin's, Dublin, D02 W086 www.camdencourthotel.com/en/ I’ll be there, so feel free to join! See you soon! Simone

Vision Language Models (VLMs) such as LLaVA, Qwen-VL, Nemotron VL and GPT-4o have unlocked a new era in AI where language and sight converge into a single reasoning system. These models can describe images, answer visual questions, read documents, and interpret charts — but their true power emerges when you fine-tune them on domain-specific data, teaching them to see and reason about the visual world that matters to you. In this hands-on session, we walk through the full fine-tuning pipeline for vision-language models. We begin by understanding how these architectures work — how a visual encoder like CLIP or SigLIP is coupled with a large language model through a projection layer, and how the interplay between image tokens and text tokens enables multimodal reasoning. We then move into the practical side: preparing image-text datasets, choosing the right fine-tuning strategy (full fine-tuning vs. LoRA vs. QLoRA), configuring training with frameworks like Hugging Face Transformers and PEFT, and evaluating results on real-world benchmarks. We will also discuss when and why fine-tuning a VLM is the right approach compared to alternatives like prompt engineering or retrieval-augmented generation, and how to avoid common pitfalls such as catastrophic forgetting, overfitting on small visual datasets, and misaligned image-text pairs. Bring your laptop, your curiosity, and — if you have one — a dataset you would like to try. By the end of the session you will have a clear, reproducible workflow for adapting any open-source vision-language model to a custom task. \*\*📅 Open to all levels — no prerequisites, just curiosity.\*\*

📚Reading books and discussing them are two distinct experiences! Conversations about books and sharing insights help us better appreciate literature and enrich our lives. Let's grab a drink (alcoholic or non-alcoholic) and discuss books we're currently reading or have recently enjoyed—whether poetry, fiction, or non-fiction. Bring your physical book or e-reader. There's no formal structure or agenda—just books and good conversation.💬 It's a perfect place to get book recommendations and rediscover your reading momentum if you've hit a slump. We welcome readers of all backgrounds and interests! ⚠️**Something Happened?** If something unpleasant happened to you, it may happen to others. Even if it seems minor, don't hesitate to reach out to me. 🔍 **How to find us?** * When I reach the venue, I'll leave a comment in the meetup where the group is seated. Normally, the booking is in my name, so you can ask the staff for the group. * If you're unable to find us, leave a comment in the meetup page. I'll be able to guide you. We highly encourage you to move between tables and strike up conversations with fellow book lovers. These discussions about literature and reading recommendations are often the highlight of the event! As an organizer, I'm always looking for feedback about the event and suggestions for new events, so feel free to suggest ideas to me. 💡 I look forward to seeing you all! 😊

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.

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!

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.
