Maker Night - Work on 3D projects using laser cutter, 3D Printer at TOG
**Do you like to make things? Would you like to use 3D software, lasercutter and 3D printing to help you make your idea?**
TOG has an open evening to learn how CAD software and 3D fabrication tools can help you make your project.
All you need to take part is your own laptop and some ideas on what you want to make.
This is not a taught class, more like an informal working group of self-directed makers.
We will be happy to help you explore how to use our 3D tools in designing and making your project whether you are a crafter, designer, engineer or hobbyist.
Come and have a look at the tools in our space and get some ideas on how your project can be made.

TOG Watch Night: The Secret Life of Components (Tim Hunkin)
TOG Watch Night: The Secret Life of Components (Tim Hunkin)
We’re kicking off a new bi-weekly Monday Watch Night at TOG. We’ll watch an episode of Tim Hunkin’s “The Secret Life of Components” together, then have a relaxed Q&A and discussion afterwards.
This is a friendly, low-pressure way to learn the kind of practical tips you normally only pick up through years of making, fixing, and building. Perfect for beginners, makers, repair folks, and engineers who enjoy the practical side of components and mechanisms.
How it works
\- Watch together \(one episode per night\)
\- Q&A and chat after: questions\, examples\, tangents\, and “how would we do this at TOG?”
\- If you miss a week\, no stress\. Watch it at home and come along to the next one
First session
\- Monday 26 January
\- Episode 1: Chain
\- Free and open to all
\- TOG Hackerspace \(Dublin 12\, D12 CF6V\)

DubJUG 265: GraphQL with Professor Ž
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.
Clojure Ireland
**IMPORTANT UPDATE:** Due to a fire incident at Kyodai Izakaya, It's been **temporarily closed**. Let's meet at J.R Mahon's on 1-2, Burgh Quay, Dublin 2 (across the river from Izakaya Kyodai).
We still need a venue for presentations. If anyone can help, please get in touch (e.g. via Discord). The minimum requirement is a room with a screen, or projector.
We have a Discord server, which you're welcome to join:
https://discord.gg/nCBrCXB6
Clojure Ireland is sponsored by [Taxamo - a Vertex Company](https://twitter.com/taxamo).
Tuesday Open House
TOG will be open on Tuesday evenings from 19:00 to 21:30 for a general Open House event. Expect to find members and visitors in the space up to all sorts of activities. It's a great time to drop in and see what the space is about. If you're an artist, tinkerer, maker or just plain curious, come in and see what the space is about.
Maybe you already have something to work on (or want to), have something to fix, create, design, bodge or tinker... drop in. We're also open for just for plain old social chat and hang out, with plenty of tea, coffee and biscuits. We have lots of free parking right outside our door.
Fine tuning LLM Vision Models
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.\*\*

Building Scalable Customer Identity Resolution Pipelines on AWS Using AI
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.

CBusData - Practical AI for Power BI Developers
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.
Columbus Code & Coffee 86 @ Improving
Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you!
