Hello Everyone, For this meetup, we'll have a collaboration with the Dublin Pyladies meetup. Same time, same venue. Here is the [official link](https://www.meetup.com/pyladiesdublin/events/312867801/?notificationId=%3Cinbox%3E%21452051133-1769535510412). The great folks at Anseo are graciously letting us use their upstairs room again. You are all very welcome ! See you then.

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.

Join us for some casual games @ Corrigans. All levels welcome!

**PLEASE NOTE NEW START TIME 7 PM** Beauty is hard to deny while watching olympic skaters twirling acrobatically on the ice. Or meeting a newborn for the first time, or appreciating some stunning aspect of nature. But what about those experiences makes them beautiful? And what makes certain scenes, actions or events ugly? And why don't we all agree what's beautiful or ugly? Join us at Walters Cafe in Dun Laoghaire this Tuesday and bring your views with you; buy and drink at the bar and engage meaningfully with others in a civil discourse on beauty and ugliness.

For February, the TOG Science Fiction Book Club is reading ***The Left Hand of Darkness* by Ursula K. Le Guin**. First published in 1969, this Hugo and Nebula Award–winning novel remains one of the most important works in science fiction. Set on the icy planet of Gethen, it follows an envoy sent to persuade its inhabitants to join a galactic coalition. But the real story isn’t about technology — it’s about culture, politics, trust, and identity. On Gethen, gender works very differently from what we’re used to. Le Guin uses this unfamiliar world to explore themes of communication, loyalty, isolation, and what it really means to understand another society. It’s thoughtful, beautifully written, and guaranteed to give us plenty to talk about. **Tuesday, 24th February 2026** **7:30 pm** **TOG Hackerspace, Dublin 12** As always, you don’t need to finish the book to join in. New readers are very welcome — just bring curiosity (and maybe a warm coat, Gethen is cold).

Join us for an Apache Kafka® x Apache Flink® meetup on Wednesday February 25th from 6:00pm in Dublin hosted by Autodesk! **Venue:** Autodesk 1 Windmill Lane, 2nd Floor, Dublin D02 F206 **PLEASE BRING A FORM OF VALID ID AND REGISTER WITH YOUR DETAILS FOR SECURITY PURPOSES/BUILDING ACCESS. THANK YOU!** **Agenda:** * 6:00pm: Doors open * 6:00pm – 6:30pm: Food, Drinks & Networking * 6:30pm - 7:15pm: John Byrne, Sr. Manager, Partner Applied Solutions, Confluent * 7:15pm - 8:00pm: Rishayah Kumar Trivedi, Senior DevOps/SRE Engineer, Autodesk & Douglas Hobson, Principal DevOps/SRE Engineer, Autodesk * 8:00pm - 9:00pm: Additional Q&A and Networking **First Speaker:** John Byrne, Sr. Manager, Partner Applied Solutions, Confluent **Title of Talk:** Flink State: Design Choices You Can’t Undo *(on Confluent Cloud)* **Abstract:** A practical look at how state behaves when running Flink on Confluent Cloud, the early design decisions teams often underestimate (keyed state, TTLs, upgrades, reprocessing), and the kinds of problems that only show up months later. **Bio:** John Byrne is a Sr. Manager, Partner Applied Solutions at Confluent, the company founded by the original creators of Apache Kafka®. With a strong background in data engineering, John previously worked for Slice, Registers of Scotland, and Sopra Steria, where he specialized in event streaming, ETLs, and data governance. Passionate about GIS, mapping, and ETL processes, he has delivered talks at FOSS4G and developed production-grade ETL projects incorporating spatial data and mapping technologies. In his spare time, John enjoys playing golf and coaching his local youth rugby team. **Second Speakers:** Rishayah Kumar Trivedi, Senior DevOps/SRE Engineer, Autodesk & Douglas Hobson, Principal DevOps/SRE Engineer, Autodesk **Title of Talk:** To Production and Platform: Our Kafka Journey, DR Strategy, and Kafka-as-a-Service **Abstract:** In various organisations, multiple teams have historically had to build Kafka the hard way, spending months on security hardening, compliance validation, observability, and disaster recovery, often repeating the same work with inconsistent outcomes. The result is slow onboarding, duplicated effort, and operational silos that don’t scale as more streaming use cases come online. In this talk, we walk through our Kafka production journey on AWS MSK: how we began with a POC, what it really takes to make Kafka production-ready, and the key platform decisions we had to take to standardise the architecture and operations. We’ll then dive into disaster recovery for streaming applications where the hard problems aren’t just infrastructure failover, but event continuity and restoring pipelines under pressure. We’ll share our HA DR approach for Kafka-backed systems, including an active/passive regional strategy, and practical failover/failback considerations to minimise RPO/RTO. Finally, we’ll close with our Kafka-as-a-Service (KaaS) vision for Autodesk teams: self-service, policy-driven deployments and service tiers that let internal teams onboard in hours instead of months so the product teams can focus on building streaming features, while the platform provides consistent guardrails for security, reliability, and recoverability. Attendees will leave with a checklist of production-ready requirements for Kafka, a clear mental model for DR in streaming systems and a set of platform patterns for evolving towards Kafka-as-a-Service. **Bios:** **Rishayah Kumar Trivedi (Senior DevOps/SRE Engineer, Autodesk)** Rishayah is a Senior DevOps/SRE engineer at Autodesk's data streaming and processing platform team with 9+ years of experience building scalable cloud infrastructure and automating enterprise deployments. He holds industry-recognised credentials in AWS, Kubernetes, and DevOps, and has led many initiatives improving reliability, performance, and security through Shift-left approach, IaC and CI/CD best practices. **Douglas Hobson (Principal DevOps/SRE Engineer, Autodesk)** Douglas is an accomplished Principal Devops/SRE engineer in Autodesk's data streaming and processing platform team with extensive experience in cloud architecture, infrastructure automation, and systems reliability. With a proven track record at various firms, he has led global teams in building scalable, secure, and high-performing cloud environments.

Join us for this Thursday evening cycle on the southside of the city up to the Killakee viewpoint and back. It’s a decent climb and offers some great views over the city. Warning: this cycle has a steep/long climb. Back and front lights on your bike are essential for this cycle. The total distance is 25km, and so not far but it has 350m of climbing taken on all at once. For perspective, 350m is about twice the amount of climbing as the Thursday Howth cycle. If you are unsure of your ability to do this, I recommend trying the Thursday Howth Cycle first. We do not go fast up the climb, we go as slow as needed. Here is our plan for the evening: 1️⃣We leave at 6:30PM from Portobello Harbour 2️⃣We cycle south through Rathfarham and climb up to Killakee via Stocking Lane 3️⃣ We'll head back to starting point via Cruagh Road. 4️⃣ If time allows, we'll make a stop at The Merry Ploughboy pub for a break and refreshment before heading back to the start.

**Overview** === He's back! For our February event, we are thrilled to welcome a special guest out of semi-retirement: John Ryan. As a former Snowflake employee and current Data Superhero, John has been there since the beginning. In fact, he and I co-hosted Ireland’s first-ever Snowflake event. Since the venue was a converted church, we called it the **"Church of Data."** It was the perfect setting to kick off our Snowflake evangelism. **Abstract** === Moving from on-premises data platforms to cloud isn’t just a technology change — it’s a cost and operating model shift. Many teams underestimate this and end up with performance issues, spiralling spend, or both. This session explains why traditional on-prem thinking breaks down in Snowflake, how Snowflake is designed to scale, and where customers commonly go wrong. Using real lessons from three large Snowflake customers, we’ll walk through: What “scale up” really means in Snowflake (and when not to use it) Three common mistakes that quietly drive cost and poor performance What actually worked in production — not theory, not marketing slides This is a practical, experience-based session aimed at engineers, architects, and technical leaders who want Snowflake to run faster without wasting money.

Dublin Dataviz is delighted to welcome Andy Kirk as our first speaker of 2026! Andy is the founder of [Visualising Data](https://visualisingdata.com/) and works with [clients around the world](https://visualisingdata.com/clients) as a data visualisation design consultant and prolific [trainer](https://www.visualisingdata.com/training/). He is a a four-times published [author](https://www.visualisingdata.com/book/) and host of the ‘[Explore Explain](https://www.visualisingdata.com/podcast/)’ video and podcast series. In his talk, **The 7 Hats of Data Visualisation (Revisited!),** Andy will showcase the value and richness of data visualisation as a key literacy in this contemporary digital age. We all have a stake in this, whether that is through our roles as creators, consumers or coordinators, but it can appear to be a substantial challenge to fully embrace the multi-disciplinarity of this subject, whether as individuals or more generally across organisations. Framed as the ‘7 hats’ of data visualisation, Andy will look back over his 15+ years of experience developing an expertise in this subject to present his view of the major competency ‘ingredients' that make up the all-round talent recipe of a visualiser today. He will differentiate the knowledge required from skills necessary to demonstrate, the attitudinal maturity from the technical intelligence. He will also advise on some of the strategies that will help you continue to develop and refine your data visualisation literacy. Join us for what's going to be an amazing evening, with pints in Arthurs pub surely to follow.

In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA
