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. To find out more, please RSVP and I will send you the Dive Master Contact Details.🐳🐬🐚

We are in the middle of a trilogy of topics that form a story. Our current series is around the theme of human flourishing. Last month we discussed beauty. This month we will look at how the role ‘home’ plays in our well-being. Then in June we will ask what roles do nature and nurture play in our lives? **What about a sense of ‘belonging’?** “Ah, it’s good to be home,” we say after a time of travel or business. We move to a new city or country and feel a disorientation or rootlessness. We lack a familiarity sense of place and relationships. The modern world is not a village where you know your grocer by their first name. Some may call it ‘home.’ But what is home: A building? A geographical location? A feeling in the heart and soul? A place populated by people we love or are perhaps related to? How about those who live in a country other than their country of origin: what might they think about the whole matter of home? You are welcome to come along to discuss "Longing to belong" on Tuesday, 12.May at Third Space Smithfield. NOTE: we ask for a 3 Euro donation to cover costs. Payable on the night by coin or Revolut. Thanks Socrates Cafe: a space where ideas and dialogue can flourish

Do you often think you should journal more and struggle to find a time that feels "right"? Does journaling improve your understanding of yourself and others? Do you feel that sharing can make this understanding even clearer and help you connect with others? Join us for our 1.5 hours impro journaling event. We will have some exercises prepared that will help you to be present to your emotions and thoughts as well as connect with others. Please, notice that everything that is shared during the events is confidential, and that you can share as much as you feel comfortable sharing. LOCATION: Starbucks Stillorgan, Unit 44/45 Stillorgan Village Centre, Lower Kilmacud Rd, Stillorgan, Dublin, A94 C840 FEE: 5 € to cover costs (Revolut/Cash). Please pay the fee after the event, and please buy yourself a drink before or after the event to support the venue. NOTE 1: No writing experience is required to attend this event. Only a curiosity in ourselves and others. NOTE 2: Please provide your own notebook/paper and pen.

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!

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.

**Total Eclipse of the Chart: School Redistricting Dashboards** In this presentation, we will explore the utilization of maps, sets, and SQL within a Tableau dashboard to help provide “what-if” analyses generated through the use of a mapped dashboard, providing different scenarios and the potential implications of these. While in this use case we are focused on a large school district, the concepts of utilizing existing data to explore the future impacts of modifying different geographic boundaries can be useful to many industries, balancing the mix of maps with visual analytics. **About Our Speaker** Robert Kramer is the Data Systems and State Reporting Coordinator at South Western City Schools in Grove City. He has worked there for 17 years, serving previously in the roles of Data Analyst, Programmer, and Operations Coordinator. Prior to working at South Western, he worked as a Systems Engineer at Pinnacle Data Systems in Groveport. He graduated in 2005 from The University of Toledo with his Bachelor’s in Computer Science and Engineering, and a minor in Mathematics.

Join us for a practical, beginner-friendly guide to choosing the right large language model. We’ll compare major models like ChatGPT, Claude, Gemini, and Llama, talk about when to use hosted APIs versus local models, and break down the tradeoffs around cost, speed, quality, privacy, context windows, coding ability, and reliability. You’ll leave with a clearer mental model for picking an LLM based on your actual use case instead of hype, benchmarks, or brand names. No deep AI background required. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8.
