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.

Dr [Shona D'arcy](https://www.linkedin.com/in/shona-d-arcy-5267a44/) will out line her journey developing solutions for children's speech and language therapy and discuss the challenges of AI in healthcare [Chris McCabe](https://www.linkedin.com/in/chris-mccabe-17685b16/) on his creating a new tool everyday for 100 days project. Chris has talked before on CHAI on what you can build with local LLMs and everyone enjoyed that talk.

For our next TOG Science Fiction Book Club, we’ll be reading ***Machines Like Me*** by **Ian McEwan**. Set in an alternative 1980s Britain, the story follows Charlie, who purchases one of the first commercially available humanoid robots — an “Adam”. What starts as a fascinating technological experiment quickly turns into something far more complicated, raising big questions about consciousness, morality, relationships, and what we really want from our machines (and from each other). It’s a smart, very readable novel with plenty to chew on — perfect for a good book club chat. 📅 **Tuesday, 31st March 2026** 🕢 **7:30 pm** 📍 **TOG Hackerspace, Dublin 12** As always, you don’t need to have finished the book to join in — the conversation is the point. New readers are always welcome, so feel free to bring a friend along.

Hello Everyone, For this meetup, we'll have a presentation by Gleb Gladilov about common C++ pitfalls. Gleb is a Senior Staff Software Engineer at Intel, building machine-learning compilers for Intel NPUs on top of MLIR/LLVM. A long-time open-source enthusiast, he has spent over a decade working in C++ across compilers, low-level optimization, computer vision, and high-performance computing—and still enjoys uncovering the language’s sharp edges. C++ is full of delightful traps: code that looks obvious, may even compile cleanly, but then does something… else. In this talk we’ll tour a collection of minimal examples where C++ behavior turns out to be counter-intuitive, covering operators, initialization, constexpr, and a few other sharp edges along the way. We’ll unpack what’s really happening in hope of having fun and avoiding the “wait, what?” moments in production. Slides include links to extra material (Compiler Explorer snippets, articles, and curated talks) for anyone who wants to go further.

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.

The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event. We will be hearing from Becca Powell, Director of Advocacy and Outreach at Unchained At Last, an organization whose mission is dedication to ending forced and child marriage in the United States through direct services and systems change. Unchained At Last's mission clearly meshes and addresses several of our Humanist Ten Commitments. Becca will educate us about an issue many of us may not be familiar with--but should be. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Going forward our meetings will be hybrid.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.
