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.

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.\*\*
