Holy schmoly - we forgot to post this, and it's tomorrow! Six or seven OFFICIAL SEATS left >>>>> Check your schedule first (it's not cool to not show!) BOOK HERE [https://ti.to/dublin-java-user-group/2603-loic-magnette](https://ti.to/dublin-java-user-group/2603-loic-magnette) We're flying Loic Magnette in from Belgium for.... ## JavaScript (No, Not That One!) Modern Automation with Java If you're like Loïc, as a Java developer, every time you want or need to write a quick automation script, you struggle to remember how to properly write some bash or python. On those days, you probably end up "vibe coding" it and struggle once again when you want to adapt it. If only you could write it in Java! You might say "but Java is not for scripting" and I don't want to bother with maven or Gradle. Modern Java has quietly eliminated the traditional barriers that made it unsuitable for scripting. With instant execution, shebang support, and zero-setup automation, Java has evolved into a lean scripting language that lets you write precise, maintainable code without the "vibe coding" that often comes with unfamiliar languages. In this talk, Loïc will show you how Java became a first-class scripting language and why it might just become your new favourite tool for automation. . ## **Talk 2:** AI-Powered Form Wizards: Chat, Click, Done! Forms are everywhere; tax declarations, job applications, or even signing up for a new service. Although some forms are simple, many include ambiguous fields, complicated logic, or subpar design, which frustrates users and makes them more likely to make mistakes. Completing paperwork shouldn't be like solving a puzzle. What if consumers could just chat with an AI that walks them through each step instead of having to struggle? In this session, Loïc discusses his experience developing an AI-powered form-filling helper with LangChain4j, Quarkus and other useful Java libraries. He'll go over the challenges faced and how to overcome them, such as transforming text into form data with validations, assisting users based on their input, and the role of RAG in all of that. Loïc's talk will use examples to demonstrate how AI can assist users in their daily interactions with your software, so you will have the ideas and techniques to create more intelligent and user-friendly forms. Learn how to make forms enjoyable rather than tedious by using AI to assist your users, reduce errors, and eliminate aggravation. .

You'll get an unrivalled insight to the history and culture that has shaped the capital you see today - warts and all, discover the lesser-known, intriguing oddities of our city, and get unique insider tips for the rest of your stay. Sites and topics covered include: Dublin Castle, Christchurch, Viking & Medieval Dublin, Temple Bar, fables, folklore and mythology, Trinity College, Stephen's Green, risings and rebellions, writers & rogues and so, so much more... please remember, places are limited and you must book your spot via: https://www.generationtours.com/dublin See you soon!

Dublin Dataviz is delighted to welcome Andy Kirk as our first speaker of 2026! Andy is the founder of [Visualising Data](https://visualisingdata.com/) and works with [clients around the world](https://visualisingdata.com/clients) as a data visualisation design consultant and prolific [trainer](https://www.visualisingdata.com/training/). He is a a four-times published [author](https://www.visualisingdata.com/book/) and host of the ‘[Explore Explain](https://www.visualisingdata.com/podcast/)’ video and podcast series. In his talk, **The 7 Hats of Data Visualisation (Revisited!),** Andy will showcase the value and richness of data visualisation as a key literacy in this contemporary digital age. We all have a stake in this, whether that is through our roles as creators, consumers or coordinators, but it can appear to be a substantial challenge to fully embrace the multi-disciplinarity of this subject, whether as individuals or more generally across organisations. Framed as the ‘7 hats’ of data visualisation, Andy will look back over his 15+ years of experience developing an expertise in this subject to present his view of the major competency ‘ingredients' that make up the all-round talent recipe of a visualiser today. He will differentiate the knowledge required from skills necessary to demonstrate, the attitudinal maturity from the technical intelligence. He will also advise on some of the strategies that will help you continue to develop and refine your data visualisation literacy. Join us for what's going to be an amazing evening, with pints in Arthurs pub surely to follow.

Why Not Come with a story , a poem , a wedding speech , anything that worth sharing to a gang of 10 people ? Ping me on Meetup or email sculljam @ hotmail . com . I can reveal when we meet up exactly. (not at midnight ;-) ) There is a door charge to cover the cost of the room for 2 hours. **Your Voice Found** Does appreciate the helpful staff at Carmelite centre but we are not aligned with them. This is an independent venture. **Your Voice Found** has been running for nearly a year so we are still in the early stages. Remember, there is **no commit** (not like other clubs - they wont let you "try before you buy " ) and its cheap to attend and Carmelite Centre probably have the cheapest coffee / tea in Dublin ! We meet once a month. Same convenient Dublin City Centre location. Same time. Different Dates every Month. What is there not to enjoy ? so come along and share stories , impress your boss at the next meeting or engage the family with that wedding speech you keep worrying about. We have helped loads of like minded people . I hope you are the next ! All ages. All abilities. Just ask for James.

**Cost TOUR: FREE:** **Lunch 29.50 STERLING - you pay for your own lunch at the restaurant.** Come and join us on a trip to Belfast for a tour of the Stormont Parliament buildings. Stormont's dazzling white neoclassical facade is one of Belfast's most iconic, occupying a dramatic position at the end of a gently rising 1.5km avenue. Since 1998 it has been the home of the Northern Ireland Assembly. Free guided tours meet in the elaborate Great Hall, which is made entirely of Italian marble and adorned with five chandeliers; you'll also see the Assembly and Senate Chambers and the Committee Room. From its completion in 1932 until the introduction of direct rule in 1972, Stormont was the seat of the parliament of Northern Ireland. Following the Good Friday Agreement of 1998 it became home to Northern Ireland's devolved legislative body. However, in 2017 the power-sharing agreement collapsed over the Renewable Heat Incentive scandal, and the assembly lay dormant. At research time, politicians had yet to return to Stormont. The building is fronted by a defiant statue of the arch-Unionist **Sir Edward Carson**. Nearby, 19th-century Stormont Castle, like Hillsborough in County Down, is an official residence of the Secretary of State for Northern Ireland. **DETAILS:** **08:20** Meet in O'Briens on Connolly station **08:30** Board the he Enterprise train for Belfast **10:58** Train arrives in Grand Central Station, Belfast We then have a 15 minute walk to Donegal Square North where we catch a bus to Stormont 22 mimutes. **12.00** Tour begins **13.00** tour ends Lunch booked in the Members Dining Room **cost £29.50 STERLING PAY BY CARD ONLY.** **Cash NOT ACCEPTED** **16;00 train back to Dublin arriving at 18:13** **You can tap your bank card to pay for the bus or use sterling cash.** **Only press attend** if you **KNOW you are free to come** and really want to come.

My name is Aurelie and I'm graduating with an MSc in Artificial Intelligence from the University of Limerick. I run monthly **machine learning** and **deep learning** tutorials in Dublin with a small group of people. \*\*In this tutorial, we will build a **CNN** model to classify images into categories, we will be using a public dataset. Together, we will walk through the full pipeline from data preprocessing to model training and evaluation. You will receive a jupyter notebook with reusable code showing all of these steps. No set up required, just a laptop and a google email address :) **The tutorials are limited to 15 participants and you can reserve your spot either here or by emailing aureliem219@gmail.com. Please make sure to book as soon as possible, as the registration count on Meetup does not guarantee availability.** **For more information about the tutorials:** * The tutorials are interactive and will be conducted using **Jupyter notebooks** on **Google Colaboratory** (a free, cloud-based platform that lets us write and run code directly in the browser). While **Google Colaboratory** is free to use, tasks that require more computational power (such as training deep learning models) may benefit from GPU access. In that case, Google offers a once-off payment for around €10 which can last several months depending on your usage. Some familiarity with **Python** or other programming languages is helpful but not required. Everyone is welcome to join and learn at their own pace. * The tutorial lasts for 1.5 hours. * During the tutorial, I share the Jupyter notebook with participants so they can keep it for future reference. We go through the notebook step by step together and I do my best to answer any questions along the way. * The notebook includes the complete code from data preparation to model training and evaluation. It can be reused or adapted for your own business needs or personal projects * We will be working with a variety of **Python** libraries including **Scikit-learn**, **PyTorch**, **TensorFlow**, **Keras**, **Seaborn**, **Pandas** and **Matplotlib** and the **Hugging Face** framework. These tools will help us explore different machine learning and deep learning techniques using publicly available datasets. * Each tutorial focuses on a different algorithm in depth. Topics covered include **linear regression**, **logistic regression**, **K-means clustering**, **decision trees**, **artificial neural networks (ANNs)**, **convolutional neural networks (CNNs)** for image classification, **object detection** and **natural language processing**. The goal is to break down each technique step by step, making it approachable and practical for real-world applications. This tutorial take place at the **Grafton Hotel, 32 Stephen Street Lower, Dublin 2** (We will be sitting in the lounge in the corner or on the right handside). It will run from **3 pm** to **4 pm**. **Grafton Hotel, 32 Stephen Street Lower, Dublin 2** * The tutorials are a high-level practical introduction to machine learning and deep learning and the emphasis on understanding how we process the data , train and evaluate a model with Python. We won't cover the mathematics behind it however some tutorials may have mathematical formulas as part of the algorithm explanation and some tutorials might have more complex data preprocessing as it depends on the datasets and the task we are doing. However the tutorials focus on the practical part! * *Payments need to be made in advance to secure your place and fees are non-refundable unless I need to cancel the event, in this case refunds will be made.*

Let's improve our self-awareness, by getting into the habit of writing our thoughts and emotions. & Let's enhance our curiosity and compassion in others, by giving others and ourselves an insight into the unknown lives of strangers. Join us for our 1.5 hours writing event. We will have some exercises prepared that give us the opportunity to write and share about our thoughts/emotions/experiences and use a variety of prompts. HOMEWORK: Before the event, we ask participants to reflect and write +/- 10 minutes about a time they felt jealous of someone (e.g., a friend, a romantic partner, or a family member). Participants can choose which parts of their writing they feel comfortable sharing. **FEE:** €5 to support the group. Please pay the organiser at the event. We accept cash/revolut/paypal. **NOTE 1:** No writing experience is required to attend this event. Only a curiosity in ourselves and others. **NOTE 2:** Please provide your own notebook/paper and pen.

In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA

Meeting Room 2b, Main Library Join us for a welcoming evening of reflection, gentle music, and meaningful conversation. We’ll begin with a short grounding moment, followed by a brief reading from spiritual or philosophical traditions, and an open reflection circle where participants can share (or simply listen).
