An Examined Life - A discussion group to exchange ideas and opinions related to science, economics, psychology and philosophy. The format is that we select a theme and pick a book related to that theme to discuss. The link to the book will be posted and also a talk/podcast related to the book should you not have time to read the full book before the meetup. Pre-reading is not mandatory, however, everyone will get more out of the session if you read the book or listen to the short talk. The aim is to meet in Wetherspoons. Usually we are at a long table near the front window or, if not, a long table downstairs. Ask around and I'm sure you'll find the group!

✨ We are delighted to be hosted by Liberty IT this month. 🎤 Talk details will be coming soon. 📚 And thanks to [Packt](https://www.packtpub.com/), we have a physical book to raffle after the talk: * [Python Illustrated: Not another boring Python book, learn programming the fun way](https://www.packtpub.com/en-us/product/python-illustrated-9781836646327) by Maaike van Putten and Imke van Putten \-\-\- 🎟️ **PLEASE REGISTER ON LUMA TO ATTEND:** **[https://luma.com/pm0gpsda](https://luma.com/pm0gpsda)** \-\-\- **​Schedule (\*subject to change)** * ​18:30 Event Starts * ​18:40 Welcome and Introductions * ​18:50 Talk: Learning in Public, Again by Sarah Novotny * 19:15 Networking after * ​20:30 Event Ends **TALK DETAILS:** **TALK 1: Learning in Public, Again** (10-20 mins) I spent two decades building software communities. Kubernetes, NGINX, MySQL. And then I moved to Dublin and enrolled in a master's programme in political science at Trinity College. People have asked me why I took a left turn away from a perfectly good career. The honest answer is that I kept running into questions my industry experience couldn't answer. How do open source communities actually function as political systems? What does "technological sovereignty" mean when the phrase shows up in EU regulation, national security strategy, and corporate marketing decks, all in the same week? Why is corporate investment in OSS not patently obvious? I needed different tools. So I learned Python. Not the "I'll automate a spreadsheet" kind. The "I'm running topic models on 1,600 EU consultation responses to figure out who is shaping digital policy and how" kind. I learned statistics. I learned how to scrape legislative databases. I learned how to be bad at something in front of people half my age, which, if you've spent twenty years being the expert in the room, is its own special discipline. This talk is about what happens when you decide the next interesting problem matters more than the comfort of the last solved one. It's about moving countries, going back to school, picking up a programming language for the first time in decades, and discovering that the willingness to be a beginner is a skill that compounds. Whether you're 25 and pivoting, 45 and reinventing, or anywhere in between, the capacity to start over is not a concession. It's a superpower. **About Sarah Novotny** Sarah Novotny is a technology executive renowned for her pioneering leadership in open source, cloud computing, infrastructure automation, and big data.. She has led an Open Source Ecosystem and Strategy group for both Microsoft Azure and Google Cloud Platform. During her tenure at Google, Sarah played a pivotal role in expanding the Kubernetes open source project leadership and represented the company during the founding of the Cloud Native Computing Foundation. At her core, she is driven by the ethos of open-source collaboration – where every line of code and every contributor interaction contributes to a greater collective purpose. She believes in fostering mutual aid and community care to build bridges across diverse coding languages and experiences. * [https://sarahnovotny.com](https://sarahnovotny.com/) * [https://linkedin.com/in/sarahnovotny](https://linkedin.com/in/sarahnovotny) **TALK 2: I'm a Software Engineer and I (Barely) Code** (10-15 mins) I dabbled in coding for years while working as a library manager, learning to write "Hello World" in at least four languages before moving to Belfast and coding my way through a master's degree in Software Development. I took my first job as a software engineer only to find that - surprise! - I barely code at all. I work in Machine Learning Operations, and while I touch a whole lot of Python code, most of my time is spent working with configuration files and infrastructure-as-code. Can I still call myself a software engineer if I'm not writing code? What does this mean when I’m faced with the next inevitable coding assessment, at this job or the next? This talk raises questions about what defines a software engineer in a world of increased software abstraction and, while I promise I won't talk too much about it, AI. **ABOUT Frances Veit** Associate Software Engineer, Liberty IT Frances is originally from Minneapolis, Minnesota, but has called Northern Ireland home since 2018. She holds a Master's degree in Library Science from the University of Wisconsin-Madison and a Master's in Software Development from Queen's University, Belfast. Frances is glad to have done her software training before AI was on the scene, but she's equally grateful to have an on-screen mentor while she figures out what she's doing. When she's not not-coding, she's at the beach with her two little kids, or baking. * [https://linkedin.com/in/frances-veit-49169926/](https://linkedin.com/in/frances-veit-49169926/) \-\-\- 🎟️ **PLEASE REGISTER ON LUMA TO ATTEND:** **[https://luma.com/pm0gpsda](https://luma.com/pm0gpsda)** \-\-\- **💖 THANKS** **Sponsors** * [Liberty IT](https://www.liberty-it.ie/about-us/overview): Hosting * [Packt](https://www.packtpub.com/): Raffle prize **Community Partners:** * [Coding Grace](https://codinggrace.com/) * [PSF](https://www.python.org/psf/): Meetup * [PyLadies](https://pyladies.com/) 🔍 **FAQ** **Note that all our events are 18s+.

There will be other people on this course besides people from this meetup. There are different course dates, so RSVP and you can choose another date if you wish. The cost of this PADI Scuba Dive course is about 650 euros or so and it is a part time course. The duration is over about a month or so. https://www.padi.com/ https://youtu.be/kvmgy4XsqrU This (PADI) scuba dive course is also a legal qualification requirement for scuba divers. The first dives will be in a large swimming pool 5m deep. If you like you can also do a pool try dive to see how you go before you start your dive course. You will be shown how to use scuba diving equipment. This PADI Open Water Diver course consists of three main phases: * Knowledge Development (online, home study or in a classroom ) to understand basic principles of scuba diving (5 modules) * Confined Water Dives to learn basic scuba skills (5 pool training dives). * Open Water Dives to review your skills and explore (4 open water dives). * Once you become a PADI qualified scuba diver you can do open water boat dives and weekend Atlantic sea boat dives and or Fyords boat scuba dives trips will be avaliable to you around Ireland and overseas. ## **Course Schedule (3-Week Format)** ### **Week One** **7:00 pm – 9:00 pm:** Induction, equipment orientation, safety briefing **9:00 pm – 10:00 pm:** Confined Water Session 1 ### **Week Two** **7:00 pm – 9:00 pm:** Knowledge Development + skills briefing **9:00 pm – 10:00 pm:** Confined Water Session 2 ### **Week Three** **7:00 pm – 9:00 pm:** Knowledge Development + final review **9:00 pm – 10:00 pm:** Confined Water Session 3 ✅ After your pool training, you're ready for your **two open-water dives.** People use Sea swimming for its healing salt properties,it washes viruses, bacteria and cleanse your skin amongst other things due to the sea salt content. There has been a large increase in people going swimming these last years. Scuba diving also refreshes your mind like hiking to start a new fresh day and a new work week. Anyone thinking about doing scuba diving this would be a good starting point for you. As usual this is a sporting event, so when you RSVP and attend this course, every person is directly responsible for their own health and saftey and accept full responsibilty.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

**Abstract:** This is a practical playbook for building a production-grade data lakehouse. It walks through foundational principles — naming conventions, least-privilege access, automated CI/CD testing — before diving into medallion architecture. Furthermore, metadata-driven design patterns show how configuration tables and dynamic notebook orchestration eliminates hard-coded pipelines. The deck covers star schema modeling, guidance on choosing between Spark, Pandas, and SQL, and data quality enforcement using DQX with YAML data contracts.

**Welcome to Drunken Philosophy** a casual, curious social discussion **Optional topic for this meetup: What's up with all the AI hate?** A recent survey found that 74% of Americans have a negative view of AI, and I want to know why. Come out and debate whether AI is good or bad. My hot take: a labor-saving tool that could potentially help cure cancer gets called dangerous because it might raise unemployment or cause a speculative investment bubble, that tells you a lot more about capitalism and the economic system we live under than it does about the tool itself. As a computer programmer, I think AI is a wonderful tool that has increased my productivity by at least an order of magnitude. I'd go so far as to say Claude Code is the best tool I have ever used. Debate me and name a better one. Is AI potentially dangerous? Yes, but so are a lot of tools. Chainsaws. Steam engines (early ones would occasionally explode and kill everyone in the room). Do you think cavemen sat around debating whether fire could be used as a weapon or for self-harm, and decided not to discover it? I have two friends who hate AI for opposite reasons: one thinks it's a fad and not useful, and the other thinks it's going to take over everything and cause human extinction. Come out tonight, have a friendly debate, and make some friends. No lectures. Friendly crowd. Drop in for one drink and stay if it's fun.
