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 \(Dublin 12\, D12 CF6V\) Full details: https://www.tog.ie/2026/01/tog-watch-night-the-secret-life-of-components-tim-hunkin/

Come along to get rid of the number one fear people have. Every week we have new members and people starting from scratch so you will not be alone. Everything is based around what you're comfortable with and you don't have to stand up, talk or do anything if you don't feel like it. But you will have the opportunity to speak at least 4/5 times a night. You can come along to see what we're doing and take part if you like. We will be running this for beginners every week and anyone is welcome to join us to learn and get better together. Hope to see you there :D We charge €5 to help towards the room rental.

Come to this fascinating lecture at the James Joyce Centre as part of the Bloomsday Celebrations. COST: 11:70 euros Tickets from Eventbrite Dive into the "Dublins" of literary legends Jonathan Swift and James Joyce in this special Bloomsday Festival lecture by Dr. Brendan Twomey. Join us at **[The James Joyce Centre](https://www.jamesjoyce.ie/ "https://www.jamesjoyce.ie")** for a special **[Bloomsday Festival](https://www.bloomsdayfestival.ie/ "https://www.bloomsdayfestival.ie")** lecture on **Monday, 15 June at 5:30 pm** by **Dr. Brendan Twomey** about how the city of Dublin shaped (and were shaped by) two of its most iconic writers: **Jonathan Swift** and **James Joyce**. This illustrated talk will use the **[Brookings map of Dublin](https://www.dublinportarchive.com/collection/charles-brooking-map-dublin/ "https://www.dublinportarchive.com/collection/charles-brooking-map-dublin/")** of 1728 and Swift's comments on Dublin city as a starting point. Swift and Joyce may have been separated by two centuries but to say that they were opinionated about their native city is an understatement. Both writers have instant global visual and literary recognition that is forever associated with Dublin and both are still relevant "after all these years." Both sought, albeit using very different registers and coming from very different social, economic and cultural perspectives, to capture the essence of the spirit of their home city as reflected in its people, its politics, as well as its physical manifestation in its streetscapes and its buildings. Details: **Book your ticket on Eventbrite BEFORE pressing ATTEND!** **DETAILS:** **17:30:** Meet Inside the James Joyce Centre. It is free seating, so we will go to the lecture Hall as soon as opens. 6:00pm Lecture begins 7:00om Lecture ends We will go to cofffee afterwards.

We will mindfully walk by the Liffey and do some short sitting meditation in the rose gardens. Meet first in the car park and walk to the adjacent memorial park.

Most places we meet other gay men are bars, apps, or busy social scenes. This is something a little different. Gay Men’s Circle is a relaxed evening where you can connect with other men in a more real and grounded way. No pressure to perform, impress, or have the right words. Some men share what’s going on in their lives. Others simply listen and take in the conversation. Both are completely welcome. Many people say they rarely get the chance to spend time with other gay men like this. It is often surprisingly refreshing. No experience with circles or men’s work is needed. Just come along and see how it feels. ### Practical details Please bring **€5 to cover the cost of the room** No entry **10 minutes after the start time** We meet **downstairs in the Theatre Room** Ring the **front door bell** to get in (the café is closed on Mondays) If you RSVP and cannot make it, please update your RSVP so someone else can attend.

Dublin Data Science is having an event in Zalando for June. Zalando is one of the top Europe’s leading online fashion platform, connecting 62 million active customers with more than 7,000 brands across 29 markets. We will have two talks: one from Senior Data Scientist at Zalando, Alex Martinelli, and one from DDS regular Duncan Healy. **Talk 1:** **Data Science at Zalando** and a non-hyped view on how we optimize the use of LLMs for different tasks In this talk I'll provide an overview of the data-science work happening in Zalando, focusing on core projects built right here in our Dublin office, including product-matching, product-tagging, and Aspect-Based Sentiment Analysis (ABSA) for customer reviews. While the rapid evolution of LLMs has made them powerful tools for these tasks, we adopt and evaluate them carefully. I will discuss our practical, balanced approach to adopting and evaluating LLMs, demonstrating how we integrate them into our existing pipelines to achieve optimal performance while keeping infrastructure costs in check. Alex Martinelli is a senior data-scientist at Zalando, previously worked for IBM-Watson. Mainly focusing on representation-learning, computer-vision and generative-models. Additional hobbies and interests include procedural-computer-graphics in Blender, drawing and lucid-dreaming. **Talk 2:** **How to Tame the Dragons of Data** Duncan Healy is a freelancer and DDS regular, he made the mistake of pontificating too often about LLMs and databases and now has to give a talk about it.

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.

**\*\*\* We've Moved! Bold Penguin - 6555 Longshore St, Dublin, OH 43017 \*\*\*** Ryan Carroll **Local AI in Rails: Fast, Cheap, and Predictable** Rails apps usually reach for external AI services when they need “intelligence,” but that approach can bring latency, cost, and unpredictability along for the ride. This talk shows a different path: running a Japanese sentiment model directly inside a Rails app, using ONNX Runtime, background jobs, and real-time updates to keep the user experience fast and responsive. Using a small app called **Sentiment Omikuji** as the case study, the talk walks through how the model was trained in Python, exported to ONNX, and loaded into Ruby for local inference. It also covers how Japanese text is tokenized, how the sentiment output drives a fortune generator, and why the app uses Solid Queue to keep model work off the request path. Along the way, the talk explores the tradeoffs of local inference versus API-based LLMs, and why classic machine learning can still be the right tool for focused problems. Attendees will leave with a practical architecture they can adapt in their own Rails applications, plus a clearer picture of when local AI makes sense, how to keep it predictable, and what it takes to make it feel good in a real app. **AGENDA:** * See updates to parking below * Doors open at 5:30, feel free to come and hang out before! * Official start of the meeting is at 6:30pm * After the meeting is done, we will go hang out at a nearby space in Bridge Park!

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD
