Electronics Night
These are our regular Monday evening electronics nights. Everyone from absolute beginner to experienced is welcome. These evenings are not classes or tutorials, rather a very friendly informal evening.
We have a wide range of people who come. Some are absolute beginners who do not even work or study electronics, but are interested to know more. Others have something that they are already working on. We almost always have some first time visitors and we always give them a tour of the space.
Come in with your Pi, Arduino, or whatever you have. Bring your laptop. Maybe you want to make something, solder, breadboard or use our electronic gear. Maybe you have some vague ideas and just want to get started. Or maybe you’re just curious……if so, it’s fine to come along and just see what others are doing.
If you would like to get even more involved and have the full use of our space, we would be delighted to have you as a full member. Membership brings many benefits.
We are located behind Mr Price and the Bright Lights store on Kylemore Road. We have lots of free parking available.
Public Speaking Monday Meetup - New Location
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.
Gay Men’s Circle – May 25
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.
Maker Night - Work on 3D projects using laser cutter, 3D Printer at TOG
**Do you like to make things? Would you like to use 3D software, lasercutter and 3D printing to help you make your idea?**
TOG has an open evening to learn how CAD software and 3D fabrication tools can help you make your project.
All you need to take part is your own laptop and some ideas on what you want to make.
This is not a taught class, more like an informal working group of self-directed makers.
We will be happy to help you explore how to use our 3D tools in designing and making your project whether you are a crafter, designer, engineer or hobbyist.
Come and have a look at the tools in our space and get some ideas on how your project can be made.

The Last Mile of Data: Bridging the Gap Between Warehouse and Business
**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

Transformers in Pratice
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

**Abstract**
Like it or not, AI agents are now capable of turning a quickly written paragraph of requirements into a pull request that is ready to be integrated into real-world production applications and it's now our responsibility to make sure AI doesn't go rogue and take down prod - or corrupt our data by misunderstanding the requirements or our existing schemas. 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.
