Software Craftsmanship

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.

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.

If anyone attending has mobility issues, there is a lift. Members who attended the previous tours will agree that the tour was very enjoyable and Dr. Whelan kept us enthralled with his great wit and knowledge. In 1671, a charitable school for boys of poor families was established called the Hospital and Free School of King Charles II, Dublin. It became known as the King's Hospital or Blue Coat School because of the boys' military-style blue uniform. The original school built on another site, was deemed to be in danger of collapsing by the early 1770's. Thomas Ivory, Master of the School of Architectural Drawing in the Dublin Society prepared a set of thirteen drawings in 1776 for a new design. The building was never finished to Ivory's design. In December 1783, the building was opened. and the first boys moved into the school. In 1894, the incomplete tower was removed and replaced by the present cupola. Blackhall Place remained the home of the Blue Coat School until 1968. The building was acquired by the Law Society in 1971 and having completed substantial renovations, it was opened as the headquarters of the solicitors' preofession in 1978. The Chapel, now known as the Presidents' Hall, has considerable distinction with its fine plasterwork of the Georgian period and was enhanced in the 20th century by the erection of a stained glass east window by the Irish artist, Evie Hone. I look forward to seeing you there.

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.

We will start the session with some light stretching exercises to warm us up, and help to prepare us for the run. The pace of the run will be steady, depending on who is running with us on the day. Days when we have a large group we may break into multiple groups, each operating independently at their own pace. Saturdays are good for intermediate runners, and is usually a 10km run, again at a steady pace. If you're looking to get into running, come along on Tuesday or Thursday mornings and I will coach you, at your pace, to get you up to running (jogging) to 5km without stops. The only thing I will ask, if you're a beginner, is that you're able to walk for approx 30 minutes at a relaxed pace. PLEASE NOTE: That, if you RSVP a particular event, then please ensure that you attend, as there may be other members relying on you for company on the run. IMPORTANT NOTE: Any run or activity that you participate in with the group will be at your own risk. Usually we have a post run (after our cool down) coffee in the Dash container at the Hole in the Wall pub.

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.

The goal of this group is simple: to support and encourage each other to write more (myself included). I love writing short stories, but too often life gets in the way and I find excuses not to do it. This monthly group gathers together on the last Tuesday of every month in the lovely *Third Space* cafe in Smithfield to share and get feedback on our work. We’ll each get the chance to share an extract from a piece we’ve written, read it aloud and get feedback (in a nice quiet creative space). Any form of writing is great – whether screenwriting, poetry, flash fiction or something else. We pride ourselves in promoting a really friendly, safe space to share freely, but if you’d prefer to listen for the first while, that’s cool too. If you fancy coming along: * RSVP to an event * Come along to a session * Get added to our WhatsApp group once you're there * Add a copy of your piece to our shared drive (so we can follow along as you read) * You'll get 4 mins to read your work, and 4 mins of feedback We have lots of regulars but always love welcoming new people, perspectives and writing, so do feel free to come along and I hope you enjoy it!

**Rescheduled to 1st of Aprli.** Let's meet over drinks and/or food, at ***Kyodai Izakaya*** on Eden Quay, in Dublin. We still need a venue for presentations. If anyone can help, please get in touch (e.g. via Discord). The minimum requirement is a room with a screen, or projector. We have a Discord server, which you're welcome to join: https://discord.gg/nCBrCXB6 Clojure Ireland is sponsored by [Taxamo - a Vertex Company](https://twitter.com/taxamo).

Zwangloses Treffen in der Bar des Harcourt Hotels für Muttersprachler und besonders alle die ihre Deutschkenntnisse praktizieren wollen. Easy-going meeting in the bar of the Harcourt Hotel for native speakers and especially all who want to practice their German.

**Cost: £6.00 (Sterling). PAY ON THE DAY. RSVP OPENS :14 /03/2206 at 10.31 am** Come and join us for a self-guided tour of this fascinating exhibition. On 11th November 1976, a devastating fire at Malone House in South Belfast – where the Ulster Museum’s fashion collection was being stored at the time - led to the near-total loss of the original costume and textile collection. Fifty years on, the Ulster Museum fashion collection stands stronger than ever. A collection reborn through significant acquisitions, a future-proof collecting policy and generous donations, making it one of the most important collections in Western Europe. *Ashes to Fashion* marks this extraordinary milestone with a stunning showcase of fashion from the eighteenth century to today, from historic garments to contemporary pieces by Chanel and Versace. The exhibition will feature rarely-seen items, including the sole survivor of the 1976 fire - the Lennox Quilt, an exquisite 18th-century embroidered quilt – which was not lost in the fire because it happened to be on display at the museum. Renowned designers like Alexander McQueen and Carolina Herrera, as well as designs by Irish fashion icons JW Anderson and the late Paul Costelloe, will all be on show alongside many more[ ](https://www.ulstermuseum.org/temporary-exhibition/ashes-fashion)iconic names. ‘Ashes to Fashion’ will also showcase a selection of the latest acquisitions to our fashion collection, including objects from the [Lanto Synge](https://www.nationalmuseumsni.org/article/lanto-synge-cultural-gifts-scheme) Needlework Collection, offering pieces that symbolically replace items lost in the fire. **Details:** Meet outside O'Briens at **08:25** **08:30:** Board the Enterprise train to Belfast - Y**OU MUST GET A TICKET TO TRAVEL ON THE TRAIN** **8:50 Train departs** **10:55** arrive in Belfast **Change platform , one stop to Botanic,** **Short walk t**o the Ulster Museum Self-guided tour of museum Lunch **BOOKED i**n museum Cafe Return to Grand Central Station Train Departs Belfast **16:0**0 Arrive Connolly Dublin at **18:13**

If you’ve ever left a meetup thinking *‘Nice people, but nothing really happened’* — this space was created for you. This is a **curated in-person meetup** for growth-minded professionals and founders who value **focus, depth, and action** over noise and small talk. We meet **every 6 weeks** in a **private room inside a bar** — not in the middle of a loud crowd, not at shared tables, and not competing with background music. This space is intentionally chosen so that: * conversations can go deep * you can actually hear and think * your time feels **protected**, not diluted This is not a “drop-by networking event.” It’s a **deliberate environment for clarity, motivation, and execution**. ### **What makes this different** People often say: * “I hate loud bars where you can’t talk properly” * “I don’t want to pitch or be pitched” * “I don’t want to waste another evening with nice conversations and no outcome” This meetup is designed to avoid exactly that. Here, you: * come with clear goals * leave with concrete next steps * meet people who are **already taking action** ### **Why this is paid (€9.99)** The fee is not about exclusivity for its own sake. It’s about **commitment and quality**. Free meetups often lead to: * last-minute no-shows * people who just want to “see what it’s about” * shallow networking without contribution The small fee ensures: * people show up intentionally * everyone respects the space and each other * the room stays focused and valuable You’re not paying for access. You’re paying for a **high-quality room and high-quality people**. We have a presale https://buy.stripe.com/9B600ifW41lPbz43Re9R606 you can save 25% by getting your ticket before the event. ### **Who this is for** ✔ Professionals, founders, freelancers ✔ People actively working on something ✔ Those who prefer **investing time** over spending it ### **Curation & Selection** To protect the group’s quality, **attendance is curated**. I personally review applications. **Quality over quantity — always.**

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.

Pay attention! We’re delaying a week for those of you who may be on Spring break and/or celebrating the holiday. Ok, no pancakes, but waffles-a-plenty. Join the local UX and Digital Design community for a casual monthly breakfast. Look for us upstairs!
