For our next Tog Science Fiction Book Club, we’ll be reading *Camp Concentration* by Thomas M. Disch. First published in 1968, this dark and thought-provoking novel blends science fiction, politics, and satire. Set in a dystopian future, it explores imprisonment, intelligence, power, and the cost of human progress. It should give us plenty to chat about on the night. We’ll be meeting **in person** at **Tog Hackerspace** on **Tuesday, 28th of April at 7:30 pm**. Whether you’ve read the whole book, only started it, or just want to listen in, you’re very welcome to join us. Our book club is always open to new people, and it’s a great way to discover new science fiction and meet fellow readers. **Book:** *Camp Concentration* by Thomas M. Disch **Date:** Tuesday, 28th April **Time:** 7:30 pm **Location:** Tog Hackerspace Come along for sci-fi, discussion, and good company.

Hello Everyone, For this event, we'll have a collaboration with the Linux Developer Ireland meetup. IMPORTANT: We had to change the venue for this one 200 meters. It is now the Abbey room at the Camden Court hotel. There is a bar next to the room for drinks before and after the talks. You can find the details and sign up here: https://meetu.ps/e/Q0Lgz/sZHJs/i As always, you can watch past events videos on our peertube channel: https://indymotion.fr/c/cppdug/videos And join the chat on matrix: https://matrix.to/#/#cppdug:gitter.im See you there

**🌟 Community Read: Tomorrow, and Tomorrow, and Tomorrow by Gabrielle Zevin : First-Timers Welcome** The group is meeting to dig into the acclaimed Tomorrow, and Tomorrow, and Tomorrow by Gabrielle Zevin alongside fellow readers in a laid-back setting, and the whole evening is centred around the book and each other. There is no pressure to finish the whole book, and mark the passages that made you stop and think, and bring your feelings about it — since the best discussions come from genuine reactions not prepared speeches. The format is relaxed and member-led — with the conversation often surprising even long-time members, and the discussion regularly runs well over time because no one wants to stop. Newcomers are always made to feel at home — and the only thing you need is an interest in the book and good conversation, all you need is yourself and an opinion, and you will leave having said more than you thought you would. --- **Worth having on hand:** - The book — whatever format works for you - A list of moments or lines you want to discuss - A hot drink if you like — we are here for a while - Your genuine reactions however complicated **Here is how the evening goes:** 1. Everyone finds a seat and the discussion opens whenever the group is ready 2. Discussion opens with an initial question and flows from there without a set agenda 3. The evening finishes with a discussion about what to read next ⭐ *"Worth it even when I only read half the book — even the books I was unsure about became interesting in the discussion"* – regular attendee --- 📚 Reading alone is one thing — reading together is another — RSVP and come as you are and the evening takes care of itself once you arrive. The conversation gets better with every reader in the room. 📚

Welcome to an evening with IBM Research where we discuss AI, Agents, NASA and everything in between. An event hosted by **IBM Research** \- PyData Ireland is excited to be a community partner\. This is an inaugural **Open Source Science Dublin** meetup, where cutting-edge scientific research meets open-source technology, AI, and cloud-native infrastructure. ​ Expect **technical deep dives**, **cross-disciplinary conversations**, and (of course) **pizza** 🍕. For this first event, we’re exploring one of the most exciting frontiers today: **agentic systems for scientific discovery**, and how autonomous and semi-autonomous AI systems are transforming the way research is conducted, validated, and scaled. ​ You’ll see real-world systems in action, hear from both applied and research perspectives, and walk away with a clearer picture of how agents are moving from hype to scientific infrastructure. ## **Talks** ​**Accelerated Knowledge Discovery at NASA: Building an Agentic AI Research Companion** * **Speaker:** James Barry, Staff Research Scientist, IBM Research * **Description:** A practical look at NASA’s AKD platform: a chat-driven frontend orchestrating a multi-agent backend (planner + literature/data/code search) to turn questions into traceable, end-to-end scientific research—faster, more systematic, and with human oversight. ​ **Production-Ready AI Agents: Containerization, Sandboxes, and the LangChain Stack** * **Speaker:** Fabio Lorenzi, Staff Research Scientist, IBM Research * **Description:** Building secure, scalable AI agents for industrial time series analysis using isolated code execution, LangGraph for agent orchestration, and FastAPI for production deployment—bridging foundation models and real-world maintenance workflows. **Science in the Agentic Era: Structured Experimentation with *ado*** * **Speaker:** Michael Johnston, STSM, Discovery Systems; Manager, Next Generation Systems, IBM Research * **Description:** A research-first framework for agent-assisted discovery: *ado* encodes the problem space and experimental plan as schemas, enabling agents to propose and refine studies while keeping every run transparent, reproducible, and scientifically auditable.

**Hosted by Intercom’s Paul Vickers and Patrick Lindstrom** Join us at the Intercom Dublin office for an evening focused on the "Last Mile" of data engineering—turning solid infrastructure into immediate business value. Over the last two years, Intercom migrated to Snowflake and rebuilt our data foundations from the ground up, creating a trusted, high-quality layer of core data models. But we realized that great data is only useful if people can actually use it. In this session, the Intercom Data team will share how we are moving up the value chain—going beyond static dashboards to build intelligent, interactive tools that empower our GTM teams. **The Agenda:** **Breaking the SQL Barrier: Scaling Insights with Claude & Snowflake** Even with perfect data models, the "SQL Wall" often forces business leaders to wait in a queue for answers. We’ll demonstrate how we used Claude Code and Snowflake MCPs to remove this bottleneck, allowing non-technical users to query our Data Warehouse directly and create sharable artifacts of their analysis. See how we combined strict governance with an AI interface to turn "data tickets" into instant, self-serve answers. **From Insight to Action: Building 'Cockpit' on Snowflake Container Services** While chat enables exploration, some workflows require action. We will pull back the curtain on Cockpit, a full-stack application built by our Data Science team to help Relationship Managers optimize customer outcomes. Learn how we used AI-assisted coding ("vibe coding") to build the app and Snowpark Container Services to deploy it—proving that Data teams can build powerful software, not just reports. **From Idea to Real-Time Fraud Detection in Snowflake ML** In this session we’ll build a real-time fraud detection service end-to-end inside Snowflake. Starting from a natural language idea, we’ll use AI-assisted development to generate synthetic transaction data, explore patterns, and train an ML fraud model with Snowflake ML. We’ll then deploy it to Snowpark Container Services and expose a low-latency REST endpoint for live transaction scoring. You’ll leave with a practical pattern you can reuse for other real-time ML use cases such as credit risk scoring, real-time recommendations, or anomaly detection on operational data in Snowflake. **Location** Intercom office (near Stephens Green) **Event Schedule** * 6:00 PM: Networking with pizza and drinks * 6:30 PM: Breaking the SQL Barrier: Scaling Insights with Claude & Snowflake, Intercom * 7 pm From Insight to Action: Building 'Cockpit' on Snowflake Container Services, Intercom * 7.30 pm 10 minute break * 7.40 pm From Idea to Real-Time Fraud Detection in Snowflake ML, Max Zito, Snowflake * 8.10 pm Chats with drinks * From 9 pm More chats in a nearby pub

The next Dub\|Sec meetup will take place in the Wexford Room of the Camden Court Hotel on May 27\, 2026\. We'll be there from 6.30pm. Our first speaker will start at around 7pm. **19:00 - Talk 1: The Invisible Thread: From Retail Data Breaches to Phone Scams.** by Vadym Melnychenko How “Zombie Systems” in local shops become digital back-doors, why this is happening, and what a more secure “Retail Fortress” approach looks like. **19:30 - Talk 2: Securing Originality - how do we protect the quality and authenticity of human thinking** by Kalyani Korpe As universities are scrambling to respond to GenAI use and students pushing back, how are organisations protecting human thinking. Original thinking is an asset that needs governance, the same way we govern systems and data. If you would like to speak at this event or at any future Dub\|Sec\, please email us at [info@dubsec.ie](http://info@dubsec.ie/)! Join us for some drinks, food and general chat about infosec. Everyone is welcome whether you’re a pro, an amateur or just curious about the field!

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

It's been said that knowledge is knowing that a tomato is a fruit, but wisdom is knowing **not** to put it in a fruit salad. How do we reckon the difference between knowledge and wisdom? Is it possible to have one without the other, or does one depend upon the other? Does wisdom always arrive with age? Is more and more knowledge of any value in our post-information culture? Consider these and other questions at Socrates Cafe in Dun Laoghaire; buy a drink at the bar and add your voice, your point of view, to this important conversation.

In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** https://youtube.com/live/BltmWMH1zG0?feature=share

Most people use AI like a search box: they type one sentence, hope for the best, and get frustrated when the answer is generic, wrong, or useless. But getting better results from tools like ChatGPT, Claude, Gemini, and other AI systems is not about memorizing magic prompts. It is about learning how to give the AI better context. In this beginner-friendly session, we’ll break down how to make AI dramatically more useful by improving the way you communicate with it. You’ll learn how to give clearer instructions, provide examples, set constraints, ask for better output formats, and use follow-up questions to turn a mediocre answer into a genuinely useful one. We’ll cover practical techniques you can use immediately for work, learning, writing, coding, planning, research, and everyday problem solving. We’ll also touch on why these same ideas show up in more advanced AI systems, including RAG, agents, evaluations, and AI workflows. No technical background required. Bring your curiosity, your questions, and maybe one real task you wish AI was better at helping you with. **What you’ll learn:** * Why “better prompting” is really about better context * How to structure requests so AI gives more useful answers * How to use examples, constraints, and output formats * How to iterate when the first answer is not good enough * How these skills connect to more advanced AI workflows This meetup is for anyone who wants to move beyond basic ChatGPT usage and start getting more practical value out of AI. 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.
