Learn to Meditate - Free 10 Week Course - Starts Jan 13th 2026 - All Welcome - Join any week - Welcome to Sahaja Yoga Meditation, where experienced volunteers run all classes at no charge. We usually sit on chairs to achieve yoga effortlessly & spontaneously. So there is no need for mats and special clothing. All across the globe, many are seeking new sources of energy. Meanwhile, the most transformative energy of all is hiding in plain sight within us. It's natural, sustainable, and infinitely renewable. It's called inner kundalini energy. And everyone already has it — everyone! Our inner feminine, motherly energy automatically knows about us and what is needed to help us restore balance and harmony within our subtle being. It works spontaneously, effortlessly, and organically and cannot be paid for. The classes are designed to help those attending get into a genuine meditative state, which can be felt tangibly. It is pretty effortless and spontaneous. The free classes feature introductory talks, videos, practical workshops, and general question and answer opportunities, making them perfect for seekers trying to establish a state of yoga. Check our website for more free classes throughout Ireland. The idea is that you don't do yoga - you Achieve Yoga! Sahaja Yoga Meditation is a simple, time-honored technique. It helps those who enjoy it, reduce stress, and increase wellness. It brings better focus and helps people become more centered and better balanced. Anyone can do it. Founded by Shri Mataji Nirmala Devi, Sahaja Yoga Meditation is a worldwide movement for peace and self-awakening. All the meetings and classes are free of charge. Each week we go through simple meditation techniques, often with guided meditations, to help reduce stress and achieve the peace of true meditation. We share tips on how to help stay in balance during the day and how to meditate at home. The meditation is based on connecting with the inner chakras (energy centres) and balancing the subtle body. The tradition and aims of meditation are explained. In essence, to be in the present without mental activities or thoughts about the past or the future. It’s ultimately all about getting into ‘thoughtless awareness’, a natural state of being. Our website: www.freemeditation.ie Join us on Facebook and Twitter

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

Happy New Year everyone and welcome back to a new season of Socrates Cafe. We are going to weave together a triad of topics over these next three months that offer a story of life. For this first month we are going to look at the matter of ‘soul’ and discuss if there is an immaterial aspect of being human. Then in February we will move on from the nature of being human to discuss the presence of evil and what might be wrong with us and with our world. Finally, the third event in March will be a conversation on hope. Is there any way out of this mess in which we find ourselves? Each will be separate enough to discuss alone, but attending the series as a whole will add depth to each one. So to start off we are going to have a conversation about the soul. What makes us, us, as human beings? What makes me, me, as an individual? What are we made of? Are we more than animated matter? Is there an immaterial aspect to our nature that might survive the death of our bodies? When might a soul come into existence if there is one? You are invited to come along for this facilitated conversation this upcoming Tuesday evening at Third Space Smithfield. **NOTE: we ask for a 3 Euro donation** to cover costs payable on the night by coin or Revolut. Socrates Cafe: a space where ideas and dialogue can flourish.

To meet regulatory standards like Solvency II and LDTI, reinsurance firms must simulate how thousands of insurance policies perform under thousands of potential economic futures. In data terms, this creates a **"Cartesian explosion"**—multiplying two manageable datasets creates a result set of billions of rows. This massive computational workload frequently overwhelms traditional on-premise infrastructure. In this session, [Zsolt Revay](https://www.linkedin.com/in/zsoltrevay/) and [Thomas Mager](https://www.linkedin.com/in/thomas-mager-71916716/) detail the engineering behind **"Overlay,"** the internal data application PartnerRe built to solve this scaling challenge. Overlay’s architecture decouples business logic from compute power. We use **Datavirtuality** as a semantic orchestration layer, while leveraging **Snowflake** strictly as a heavy calculation engine. By using an aggressive **SQL push-down strategy**, we treat the database as a compute cluster. This allows us to process that Cartesian explosion of policy data and stochastic scenarios right where the data lives—without moving it across the network. **Key Technical Discussion Points:** * **Optimisation:** Handling massive joins via parallel processing and strategic table materialisation. * **Performance:** Using Elastic Virtual Warehouses to achieve linear scaling, reducing processing time from **hours to minutes**. * **Economics:** Using Auto-Suspend and Resource Monitors to keep this massive compute power cost-effective. Attendees will learn how to architect a solution that balances the auditability required by regulators with the on-demand agility required by actuaries. **Event Details** 📍 **14th January \| Clayton Hotel** **18:00** \| Food & Drinks 🍽️🥂 **18:30** \| Scaling Reinsurance Compliance: The Engineering Behind PartnerRe’s "Overlay" **19:15** \| Drinks & Networking 🍻 Don’t miss this opportunity to connect with fellow data professionals and gain valuable insights into efficient Snowflake use, Gen AI applications, and proving the value of solid data modeling!

Bring your broken tech and trinkets to get them fixed by the skilled volunteers at TOG Hackerspace – with a bit of help from our friends at Dublin Maker! On **Sunday, 18 January 2026**, between **12 pm and 4 pm**, TOG Hackerspace will host the first Repair Cafe of the new year in our own space. At this event, volunteers will share their expertise and passion for repair, helping you fix your broken items and breathe new life into them. Whether it’s a malfunctioning gadget, a piece of clothing in need of mending, or a household item that’s seen better days, bring it along and let the team work their magic. ### What can you bring in? * Clothes and accessories * Toys * Small electrical appliances and electronics * Small furniture … and many other things! Safety testing (PAT) for electrical devices will be available. ### What happens at a repair cafe? At the Repair Café, you sit down with a fixer and work together on your item. You can learn how to repair it yourself, or simply watch and learn from the volunteers while enjoying a tea or coffee. TOG members will also be on hand to give you a tour of the space while you wait. It’s not a drop-off service – it’s a shared, social repair session. Even if something can’t be fixed, you’ll at least go home knowing what went wrong and what your options are. ### Why join a repair cafe? Repair Cafés are a great way to support a circular economy, reduce waste, and extend the life of your belongings. Every successful repair keeps resources in use for longer, saves money, and keeps items out of the bin. They’re also a lovely way to meet people, swap stories about well-loved objects, and pick up new skills in a relaxed setting. ### Where and when? **Where?** – TOG Hackerspace, Unit 1B Motor City, Kylemore Road, Dublin 12, D12 CF6V **When?** – Sunday 18 January 2026, 12 pm – 4 pm Admission is free – but please **book a ticket so we can plan numbers** – all are welcome!
