At TOG, we love hacking, tinkering, and making things… but we’re also very good at accumulating half-finished projects. You know the ones: the “nearly working” circuit, the “just needs a weekend” code refactor, the 3D print that needs sanding, the costume that needs one final stitch, the repair you definitely meant to do months ago. So we’re doing something about it. We’re hosting a Finish-a-thon, a one-day, community-powered mini hackathon dedicated to making real progress on the projects that have been sitting in a box, on a shelf, or in a Git branch called `final_final_v3`. Whether it’s coding, crafting, designing, writing, fixing, soldering, sewing, or sorting, this is your day to get it done (or at least get it properly moving again). ### Event Details * **Date:** Saturday 24th of January * **Time:** **11:00 AM to 7:00 PM** * **Location:** TOG Hackerspace, Unit 1B Motor City, Kylemore Road, Dublin 12, D12 CF6V ### And afterwards After the Finish-a-thon we’ll roll straight into our monthly social night, but this one will be a bit special, because it’s also TOG’s birthday. 🎂 So: progress during the day, then a proper catch-up in the evening with the gang.  ### What’s the plan? Nothing too formal. The whole point is momentum and community: * **11:00 AM:** Arrive, grab a bench, tea/coffee, and settle in * Share what you’re working on (or keep it quiet and just crack on, no pressure) * Work through the day, ask questions, borrow a hand, offer a hand * No prizes, just the satisfaction of progress, plus the usual TOG encouragement and problem-solving ### What can you work on? Anything goes. If it’s a thing you started and you want to push it forward, it belongs here: * Squash that annoying bug in your project or open-source code * Finish an electronics kit gathering dust * Finally wire up the enclosure, label the panel, tidy the loom * Repair something that’s been sitting in the “I must fix that” pile * Wrap up a design, write-up, or documentation you’ve been meaning to publish * Revive a project you love but stalled on No project? Also grand. There’s always someone who’d love a second pair of hands.  ### What should you bring? * Whatever parts, tools, and materials your project needs * A laptop is usually a good shout * TOG has plenty of tools and bits, but assume you’ll take home what you bring (and any half-finished bits you create) ### No tickets this time There are no tickets or registration for this event, just show up and join in. If you’ve any questions (or you’re not sure if your project idea fits), give us a shout and we’ll point you in the right direction. See you Saturday. Let’s finish some things. 🔧✨

TOG is turning **17**, and we’re marking it the best way we know how: by rolling our regular **Open Social Night** into a proper **birthday session** with **pizza, cake, and plenty of chatting, tinkering, and general messing**. If you’ve been meaning to drop in for ages, this is a lovely one to start with. If you’re a regular, you already know the vibe: good people, interesting projects on benches, and the sort of conversations that start with “what’s that board?” and end up with someone soldering at 1am. ### When and where * **Date:** **Saturday 24th January** * **Time:** **7:00pm until late** * **Location:** **TOG Hackerspace** The space stays open until the last member calls it a night, which often means we drift happily into the small hours of Sunday morning. Pop in for 10 minutes or stay for the whole stretch, you’re very welcome. ### What to expect * **Homemade pizza** from the TOG pizza oven, rolling out through the evening * **Birthday cake** (because we’re not animals) * **A relaxed open evening**: tours, chats, and a look at whatever weird and wonderful builds are on the go * **Community craic**: talk, tunes, and the usual “oh go on, I’ll show you how that works” energy Our Open Social Nights are an easy, no-pressure way to see the space and meet the people. There’s no agenda and no expectation that you’re “good at” anything. Curiosity is the only requirement. ### Make a full day of it: Finish-a-thon earlier that day This birthday party is happening the **same day as our Finish-a-thon**, running **11:00am to 7:00pm**. So if you’ve got a project half-done, a box of parts staring at you, or a nagging “I really should finish that”, you can spend the day getting it wrapped up, then roll straight into the birthday celebrations at 7pm. Have a look here for the Finish-a-thon details: [https://www.tog.ie/2026/01/a-day-to-finish-what-you-started-finish-a-thon-2/](https://www.tog.ie/2026/01/a-day-to-finish-what-you-started-finish-a-thon-2/) ### What to bring We’ll have food covered between pizza and cake, but feel free to bring along: * A drink (or your beverage of choice) * Snacks to share * A project to show off, or something you want advice on * A friend who’s curious about makerspaces We’ve also got **plenty of free parking**, so it’s handy to swing by with gear, gadgets, or something for show-and-tell. ### Come celebrate 17 years of TOG Seventeen years of TOG is a bit mad, in the best way. What started as a small group of people who wanted a place to build and learn has grown into a proper community workshop full of skills, tools, and good humour. So come in, grab a slice of pizza, have a wander, meet the crew, and help us celebrate. **See you Saturday 24th January from 7pm.**

We will try to secure a table downstairs in the venue in order to keep the location consistent. New people who know nothing about Linux are welcome and encouraged to attend, please don't be shy. If you are new please feel free to approach one of the organisers, and we'd be only happy to help explain things as best as we can, we honestly don't mind and don't judge. We were new once ourselves :) Please note that in general, these are adult friendly meetups, therefore, we are not responsible for those under 18 in attendance. We may have events targeted at children in the future. As with any Meetup, please try to stick to your RSVP or change it to No if you can't come.

We at Freesalsa Ireland believe in growing the community, something our friend DJ Leo also believes in. Therefore, we are delighted to promote his weekly practice here on our Meetup for those of you looking to spend their Sunday in the best way. There will be a 60-minute lesson before social with the award-winning DJ Leo until 17.00. Prices stand at a very affordable: €5: Only Social or Only Class €5: for beginners class and social €7: for intermediate/improvers class and social. *Please note, class capacity is limited, so arrive early to be sure of a spot; first come, first serve. This is why we dance. To spend time with folks and have new experiences. You won't find a better group to do that with than this. See you all then.

**Hey hey! 👋** Excited to see you at our next meetup! Here's what you can look forward to: 💬 **Great chats with lovely people**! whether you're a local or from the other side of the world, you’re very welcome here! 🌍 **Not a native English speaker?** Awesome, you’ll get to practice with native speakers in a relaxed, no-pressure setting. 🇮🇪 **Are you a native English speaker?** Cool! Chat in English or find someone to practice another language with. Why not mix it up? ✨ We’re a **diverse, super-friendly, and inclusive bunch**, open to everyone, whether you’re shy, outgoing, or somewhere in between. 🎯 Our awesome organizers are always around to make sure things run smoothly and everyone feels included. 💡 One of the nicest things we hear again and again: even introverts feel at ease here. That’s something we’re really proud of. 🤝 **Instant connections!** You might walk in alone, but you'll probably leave with new friends. 📅 **This Saturday at 2:30pm!** We’ll be downstairs around the big oval table at a much-loved venue that's perfect for easy-going conversations and real connection. 🎉 **Theme: “International Mishmash”**: A chill space for people from all over (including Ireland!) to swap stories, share laughs, and practice languages if you fancy. (Shout-out to our lovely Irish regulars!) 🍻 **And after?** At 5pm, we’ll head over to the nearby **RIOT Pub** for tasty burgers and proper pints. Always a good time!!! *** **Want to support the group? 🙏** Running this thing costs over €200 a year (yep, all out of pocket for now 😅). If you’d like to chip in, we’d really appreciate it: * [PayPal](https://paypal.me/meetuppay) * [Revolut](https://revolut.me/michelf9a) (you can pay with your card, no need to be on Revolut!). Your help keeps the group going and opens the door for even more cool events (like day trips and gigs!). Cheers and see you soon! **– Michele & the Meetup Crew**

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 **K-Nearest Neighbors** model to classify data into groups (neighbours) using the built-in algorithm from **Scikit-learn**. 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. The tutorials take place at the **Camdem court hotel in Dublin 2** at **the bar or the restaurant** if the bar is full (coffees need to be ordered at the restaurant). It will run from **3 pm** to **4.30 pm**. **If the bar is busy ,we' ll meet at the restaurant.** **Camdem court hotel** **Camden Street Lower, Saint Kevin's, Dublin, D02 W086** * 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.*

This group is all about hosting a monthly in-person book club right here in Dublin City! If you're into the book we're reading and want to chat about it with others, this is the perfect spot for you. We'll meet for about 1-2 hours, enjoy some drinks and/or food, and dive into the book of the month—sharing our thoughts, exploring themes, and swapping recommendations for future reads. We suggest a €2 voluntary contribution per person to help cover MeetUp fees (cash or Revolut works). See you there!

We'll meet at The Capital One Café, 167 Easton Town Center, Space A-103. This is in the main mall where the Microsoft store used to be, on your left if you're standing at the bottom of the AMC Theater escalator. Join us on Sunday for an hour of uninterrupted wordmaking! • What we'll do Join us for an hour of writing! We’ve discovered that it’s strikingly helpful to write with other writers. See if it’s true for you at noon on Sundays. Be it a book, blog, script, essay, dissertation, resume, melody, poem or just plain work stuff, you are invited to write it with us. No one will see what you've written or give you unsolicited advice. Instead of just thinking about writing, come and get some real writing done. SCHEDULE: 12:00 - quick intros. 12:10 - timer starts: write for 1 hour. 1:10 - chat / take off / keep writing. OPTIONAL SOCIALIZING happens at 1-1:30ish. Writing is very solitary. Connecting (and sometimes even commiserating) with other writers is a cool thing. BEING LATE IS OKAY: just show up and get settled, then check-in with me after the session. If you were on time, please be willing to make room for the friendly latecomer. Happy writing and I look forward to seeing you! • What to bring Whatever you need to be able to write! Bring earbuds/earplugs if you want to block noise or the occasional conversation by other patrons. Electrical outlets are limited, so charge your devices before whenever possible. See you at The Café on Sunday!
