For our next Tog Science Fiction Book Club, we’ll be reading ***Rakesfall* by Vajra Chandrasekera**. Join us **in person** on **Tuesday, June 23rd at 7:30 pm** at **Tog Hackerspace** for an evening of science fiction discussion, ideas, and good company. *Vajra Chandrasekera’s* work is known for being imaginative, layered, and full of big themes, so this should give us plenty to talk about on the night. Whether you’ve read the whole book, only just started, or simply want to come along and listen, you’re very welcome. New people are always welcome at the book club. **Book:** *Rakesfall* by Vajra Chandrasekera **Date:** Tuesday, June 23rd **Time:** 7:30 pm **Location:** Tog Hackerspace Come along for sci-fi and conversation.

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.

An Examined Life - A discussion group to exchange ideas and opinions related to psychology, science and philosophy. The format is that we select a theme and pick a book related to that theme to discuss. The link to the book will be posted and also a talk/podcast related to the book should you not have time to read the full book before the meetup. Pre-reading is not mandatory, however, everyone will get more out of the session if you read the book or listen to the short talk. The aim is to meet in Wetherspoons. Usually we are at a long table near the front window or, if not, a long table downstairs. Ask around and I'm sure you'll find the group!

Hello there! Learn to Meditate in 2026 - Free 10 Week Ongoing Sahaja Yoga Meditation Course - hosted by Jayant, Violeta, Vivek, Seamus and friends every Tuesday - All Welcome - Join any Week - The address: Fringe Lab, Sycamore Building, Sycamore Street, Temple Bar, Dublin 2, DO2 TD81 - on Tuesday evenings from 7:30 pm until 9:00 pm With Sahaja Yoga Meditation, we usually sit on chairs to achieve yoga effortlessly & spontaneously. So there is no need for mats or special clothing. All across the globe, many are seeking new sources of energy. Meanwhile, the most transformative energy is hiding in plain sight within us, and it's natural, sustainable, and infinitely renewable. It's called inner kundalini energy. And everyone already has it — everyone!. It is often likened to an inner feminine or motherly energy which automatically knows about us and what is needed to help us restore balance and harmony within our subtle being. It works spontaneously, effortlessly, organically, and cannot be paid for. Sahaja Yoga Meditation is a simple, time-honoured technique that lets you tap into that energy and harness its power to become better balanced and better connected to yourself — emotionally, physically, mentally and spiritually. If you're having trouble juggling the challenges in your life, Sahaja Yoga Meditation might help you manage stress, master your emotions and find solutions to your problems. You may enjoy better health, better focus, and a deeper understanding of the universe and your place in it. Meditation is not just for mystics and monks. Sahaja Yoga meditation is for everyone. Anyone can do it. It's that easy. But with the Sahaja Yoga experience, you'll quickly realise it isn't your typical Meditation. It's much more than just feeling peaceful and relaxed. Sahaja Yoga Meditation has many layers, varied and deep. Explore at your own pace, in your way. Our volunteer experts are always available to help. Ready to plug into your inner energy? A few minutes of your life may be all it takes to connect to your inner energy and light the path to lifelong transformation. It's all about energy — guaranteed pure and carbon neutral, and you can never have too much of it. All classes are free. No strings, no catch. Everyone is welcome. Bring a friend.

**Building AI Products That Matter** explores what it really takes to turn AI ideas into products that create real business impact. Join us for an honest discussion on moving beyond experimentation, identifying meaningful problems, validating outcomes, and building AI solutions that scale in production. Expect practical insights, lessons learned, and real-world perspectives from teams actively delivering AI products. **🔹 Talk 1: Building AI Into Products: Why Some Efforts Fail Before They Begin** AI is rapidly becoming a core part of modern products, with teams increasingly able to add powerful capabilities in a matter of days. When done well, it can unlock entirely new user experiences, drive efficiency, and create meaningful competitive advantage. But while the technology has never been more accessible, successfully integrating it into real products requires more than just plugging in a model. Many teams move quickly to add AI features without first addressing the underlying foundations — particularly data quality and workflow design. The result is often inconsistent outputs, low adoption, and systems that struggle to deliver real value at scale. In practice, AI tends to amplify the strengths and weaknesses of the environment it operates in, making these prerequisites critical. **Speaker:** [Cathal Ó Riain](https://ie.linkedin.com/in/cathal-o-riain-298b8a1), Director of Data Products at Cubic³ Through roles with Accenture, Aon, Flutter and Cubic, Cathal has experience building and scaling data-driven products and AI-enabled systems in enterprise environments. In this talk, he explores the key foundations required to effectively integrate AI into products — from preparing high-quality data to embedding AI into processes where it can genuinely add value — along with practical lessons on how to set AI initiatives up for success from the outset. **🔹 Talk 2: The Customer Insights Stack: What It Really Takes to Build (And When You Shouldn't)** Every company sits on a huge amount of customer insight data - call recordings, support tickets, sales conversations - that rarely gets revisited. At the same time, building internal AI tooling has never been easier, leading many teams into a “build everything” mindset. But when building becomes cheap, deciding what’s actually worth building becomes the real challenge. Teams often end up with fragmented tools that don’t scale, are difficult to maintain, and fail to deliver clarity or adoption. **Speaker:** [Richard Blythman](https://ie.linkedin.com/in/richardblythman), Co-Founder & CEO of Naptha AI Richard has experience building both custom enterprise solutions and scalable productized platforms in this space. In this talk, he explores the spectrum from lightweight AI workflows using Claude Code to fully productionized customer insight systems, including the trade-offs, investment considerations, and performance comparisons against custom-built solutions. **What to Expect:** * **Interactive Q&A:** Bring your toughest product challenges; our speakers are ready for your questions. * **Networking:** As always, we’ll have plenty of food and drinks to fuel the conversation. It’s the perfect opportunity to reconnect with familiar faces and meet new people from Dublin’s product community. **⚠️ RSVP & Check-in Information** Please RSVP **only if you can attend in person.** **Transport:** The venue is easily accessible via the Green Luas Line, with direct access from Dublin City Centre. Thursday, Jun 25 · 6:00 PM to 8:00 PM IST Cubic³ Office Dublin · The Hive, Carmanhall Road, Sandyford Industrial Estate, Dublin 18, D18 Y2C9 See you soon!

Let's have some fun and exercise our creative muscles with some relaxed urban photography around Dublin's College Green. We'll meet at **Trinity LUAS stop** at **12:30**, from where we'll spend a couple of hours exploring the Trinity College campus and surrounding streets. The area should offer plenty of inspiration in terms of a variety of buildings and compelling street scenes.

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.

Kindly understand that This is Not an online event. We created this for the people to communicate with each other (in the comment section) to find their travel mates. However, since the Meetup site requires a date and time. We constantly have to update the date and time to keep the event alive. **Dear friends,** If you have plans to travel somewhere in the world, and you are looking for a travel mate/roommate, you can post it here to let others know, and maybe you can arrange to travel together. It would probably be a good idea to meet up before deciding to travel together but at least this will give you a chance to find a like-minded travel mate. **How to Choose the Right Travel-mate** 1. Have some common interests. 2. Avoid people who tend to extremes. 3. Agree on expenditures before you leave. 4. Make sure your personalities 5. Friends aren’t always good travel companions 6. Don’t go backpacking with a luxury-seeker 7. Make sure you’re able to communicate 8. Agree on a similar budget 9. Avoid picky, crazy and whiny individuals 10. Test each other on a short trip 11. You don’t have to be like a couple of inseparable lovebirds Good Luck and Cheers, Ree & Smyl

If you’ve worked with LLMs, you’ve probably run into slow inference, out-of-memory errors, or hallucinations you couldn’t explain. There’s no shortage of resources on how transformers work, but most of them either ask you to build one from scratch or get lost in theory that doesn’t connect to the problems you’re actually facing. Transformers in Practice is different. We will give a complete practical view of how transformers work, from how they generate text to what’s happening inside the model to how it all gets optimized to run on real hardware. Interactive visualizations throughout let you see key concepts in action and build intuition that actually sticks. Here’s what you’ll learn: * **Model Behavior:** You’ll learn how LLMs generate text through an autoregressive loop, selecting one token at a time from a probability distribution. You’ll see how sampling parameters like temperature shape the output, why hallucinations happen, and how techniques like RAG, constrained generation, and chain-of-thought reasoning all work within this same loop. * **Model Architecture and Attention:** You’ll look inside the transformer to understand what attention is really doing, how positional encoding tracks token order, and how multiple layers and attention heads work together to turn an input sequence into a next-token prediction. * **Scaling and Deploying:** You’ll learn why GPUs are well-suited for transformer inference and where the real bottlenecks are. You’ll build practical intuition for quantization, KV caching, flash attention, and speculative decoding, including the tradeoffs each one introuces for cost, speed, and output quality. The minimum fee is to pay the venue and avoid no show and make this group of people sustainable in the long term

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** *Customize the IDE: Building Extensions for Visual Studio Code* Visual Studio Code is one of the most widely used development environments today, and much of its flexibility comes from its extension ecosystem. 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
