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.

This beautiful and historic building has 365 rooms and is officially the largest Orange Hall in the world. It contains two museums: covering Orangeism and the British forces. It's approx three quarters of a mile from Lurgan station and looks out on some 200 acres of parkland. The tour incl access to the museums and costs 12 pounds p.p. for over 66s and 15 pounds for under 66s. The dining facilities are excellent, main courses start around 16 pounds. We'll meet at Connolly station in time for the 9.50 Enterprise train. It's best to get a Dublin to Belfast return ticket but we'll alight at Portadown to get a local train for Lurgan.

☘️Déanaimid iarracht Pop Up Gaeltacht a dheanamh. Don't worry if your Irish isn't the best. Tá sé oscailte to gach duine who wants to give irish a go! 🙌 Beidh sé saor in aisce. The event starts at 7pm and we'll place you in the specific Pop Up Gaeltacht groups. You won't miss us, there will be a big sign with "Pop up Gaeltacht" written on it! Ag tnúth le bualadh libh! ✌️💚 Note: We will be organising a paid language exchange in the same place, be aware this is not the same set up and you don't have to pay for the Pop-Up Gaeltacht. Simply walk through and join the Pop-Up Gaeltacht table. **Cad is Pop-Up Gaeltacht ann?** Is cruinniú neamhfhoirmiúil é Pop-Up Gaeltacht de chainteoirí Gaeilge ar leibhéil éagsúla (go minic i mbeár) áit ar féidir leo bualadh le chéile agus comhrá a dhéanamh in atmaisféar cairdiúil. I mBaile Átha Cliath is féidir le suas le 300 duine freastal ar chruinnithe mar seo, agus reáchtáladh imeachtaí den chineál céanna thar lear freisin. Tá an bealach isteach saor in aisce agus tá fáilte roimh gach leibhéal. **What is a Pop Up Gaeltacht?** A Pop-Up Gaeltacht is an informal gathering of Irish speakers of various abilities (often in a bar) where they can meet and talk in a convivial atmosphere. In Dublin such gatherings can number up to 300 people, and similar events have been held abroad. Entrance is free and all levels are welcome. **Cé hé Flip Lingoes?** Eagraímid malartuithe teanga seachtainiúla agus anois táimid chun Pop Up Gaeltacht mhíosúil saor in aisce a eagrú chun tacú leis an nGaeilge.

We hope you can help us bring the Irish language to life, we're really looking forward to it! 🇮🇪

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.\*\*

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.
