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.

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!

Philosophy considers that facts provide the foundation truths for our logical understanding. Fiction shapes human values, and emotional understanding. In a world of unchecked information, mis- or disinformation, how do we discriminate between fact and fiction to influence our world views? Join us Tuesday at Walter's, buy a drink at the bar and join this important and timely discussion.

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

**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!

Most people still use AI like a search box: type one question, get one answer, repeat. But the next step is AI agents: systems that can take a goal, break it into steps, use tools, remember context, and produce useful work for a human to review. In this beginner-friendly session, we’ll demystify what AI agents actually are — without hype or jargon. We’ll walk through practical examples of how agents can help with research, planning, writing, coding, operations, and personal productivity. We’ll cover: * What makes an AI “agent” instead of just a chatbot * How agents break tasks into steps * Where agents are genuinely useful today * Where they fail, hallucinate, or need human review * How to design simple AI workflows for your own work * A live demo of an AI agent-style workflow from start to finish No coding experience required. This is for anyone who wants to understand where AI tools are going and how to use them more effectively right now. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

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
