Hello Everyone, For this meetup, I'll present a lightning talk that touches on early reflection in 2020, and where we are now. I am a doctoral candidate at Maynooth university where I work on the ossia.io software. I have been involved with this software for a number of years, and this talk will present its plugin system called Avendish. We sometimes call it a “post library” because it is not really a library.... It has implication well beyond ossia.io, and introduced an approach in 2020 that resembles a number of recent projects leavening c++26 reflections. As always, the good folks at Anseo are graciously letting us use their room! You can get a drink downstairs and bring it up to the room. Avendish git repository : https://github.com/celtera/avendish Avendish Documentation : https://celtera.github.io/avendish Our matrix chat is : https://matrix.to/#/#cppdug:gitter.im And videos of past talks can be found on this peertube instance: https://indymotion.fr/c/cppdug/videos See you then ! Thibaud

What's the purpose of protest? What does it achieve? Is a cause-inspired protest too easily hijacked by important - but ultimately unrelated - right-wing or left-wing causes? What motivates people to protest? Are there ways to advocate for change apart from speechifying, flag-waving and public disruption? Consider these and other important questions this coming Tuesday; buy a drink at the bar @ Walters and add your voice to the civil discourse that is Socrates Café.

Do you like to try an indoor pool scuba dive with 🐟 scuba dive equipment🐳? If you are interested in going for this Pool scuba try dive🐬class, please RSVP early as there will be other people going beside this meetup. If anyone cannot make it on this day and wants a different date, RSVP and you can change your date to another date. I will send you the information details to book your pool dive🐡 a week that suites you. 😊 https://www.padi.com/ https://youtu.be/kvmgy4XsqrU This event is (PADI) scuba dive for First Timers who are interested in trying Scuba Diving. This will be a scuba dive in a large swimming pool 5m deep at one end. Cost is about 55 euros. Scuba dive equipment will be included and supplied. You will be shown how to use scuba diving equipment by a dive instructor. If you do well in the pool, you can go to the next step and take up an open water PADI dive course qualification. With this qualification it will allow you to do open water scuba diving world wide. Dublin open water boat dives and weekend Atlantic sea boat dives trips and or Fjord boat scuba dives trips will be also avaliable to you around Ireland and World Wide once you are a PADI Open Water qualified scuba diver. People use Sea swimming for its healing properties,it washes viruses, bacteria and cleanse your skin amongst other things due to the sea salt content. Since the pandemic there has been a large increase in people going swimming. Scuba diving also refreshes your mind like hiking to start a new fresh day and a new work week. Anyone interested, please RSVP and I will send you the booking information.

My name is Aurelie and I'm graduating with an MSc in Artificial Intelligence from the University of Limerick. I run monthly **machine learning** and **deep learning** tutorials in Dublin with a small group of people. In this tutorial, we will fine‑tune a **Named Entity Recognition (NER)** model using a **Hugging Face** pretrained model and **PyTorch**, following the structure of a **Hugging Face** tutorial. We will use an **NER** dataset from **Hugging Face**, walk through data preprocessing—including **tokenization**—fine‑tune the model, evaluate its performance, and finally run inference on a new, unseen text sample that was not part of the training set. You will receive a Jupyter notebook with clean, reusable code covering every step. No setup required beyond a laptop and a Google account to run everything in Google Colab. **The tutorials are limited to 15 participants and you can reserve your spot either here or by emailing aureliem219@gmail.com. Please make sure to book as soon as possible, as the registration count on Meetup does not guarantee availability.** This tutorial take place at the **Grafton Hotel, 32 Stephen Street Lower, Dublin 2** (We will be sitting in the lobby in the corner or on the right handside). It will run from **3 pm** to **4 pm**. **Grafton Hotel, 32 Stephen Street Lower, Dublin 2** * The tutorials are a high-level practical introduction to machine learning and deep learning and the emphasis on understanding how we process the data , train and evaluate a model with Python. We won't cover the mathematics behind it however some tutorials may have mathematical formulas as part of the algorithm explanation and some tutorials might have more complex data preprocessing as it depends on the datasets and the task we are doing. However the tutorials focus on the practical part! * *Payments need to be made in advance to secure your place and fees are non-refundable unless I need to cancel the event, in this case refunds will be made.*

Curious about what Irish SMEs are actually doing with AI? We’re getting together with the folks from The Irish Times, Buymedia, and Coolplanet to look under the hood of their data stacks. They'll be sharing exactly how they use Snowflake AI to clean up messy documents, speed up data engineering, and turn weeks of work into hours. Drop by for some honest talk about what works in the real world, plus food, drinks, and a chance to catch up with the local Snowflake community. **Right Story, Right Reader: Building a Hybrid News Recommendation Engine in Snowflake, Juliana Murphy, The Irish Times** At The Irish Times Group — home to The Irish Times, Irish Examiner, Breaking News, The Echo, and more — we publish hundreds of articles every week. The challenge isn’t the quality of the journalism, but helping readers find the stories most relevant to them, as discovery becomes increasingly fragmented across search, social, and other channels. In this session, Juliana Murphy walks through how The Irish Times built For Me — a pilot personalised content feed delivered three times daily to subscribers — using a fully native Snowflake architecture, with no external ML infrastructure or data movement outside the warehouse. The session covers the full pipeline: converting article text into 1,024-dimensional vector embeddings with Snowflake Cortex, building subscriber preference profiles from behavioural data, and using native vector similarity scoring and task orchestration to generate recommendations end-to-end within the warehouse, with output delivered to subscribers via an S3 stage. Beyond the technical build, we’ll explore the constraints unique to news. Unlike entertainment platforms, journalism must balance personal relevance with information diversity. We’ll show how editorial curation, controlled ranking logic, and user choice are embedded directly into the system design — and how those decisions shape both architecture and outcomes. Key takeaways: • Why editorial and ethical constraints belong in your data architecture, not just your product spec • Building a production-grade recommendation pipeline natively in Snowflake (Tasks, Cortex embeddings, cosine similarity scoring, Python UDFs) • What “hybrid” means in practice: combining ML signals with editorial control • Why domain knowledge matters as much as model performance **Accelerating Data Engineering with Snowflake Cortex Code, Jenny Zhou, Snowflake** This demo showcases Cortex Code, Snowflake’s AI-powered coding agent designed to automate and optimize the end-to-end data development lifecycle. We will demonstrate how Cortex Code moves beyond simple code completion by leveraging platform awareness—integrating your database schema, security context, and execution logs directly into the development workflow. **Extracting Structure from Chaos: Parsing Documents from 400+ Media Sources with Cortex AI at Buymedia, Estella Roberts, Buymedia** At Buymedia, ingesting data from over 400 unique media sources is anything but clean. Every source brings its own document formats, layout quirks, and edge cases that completely break traditional extraction tools. In this session, Estella Roberts shares how Buymedia transformed a manual, error-prone bottleneck into an automated, native pipeline using Snowflake Cortex AI and CORTEX.COMPLETE. We'll dive deep into the architecture, explore the messiest edge cases, and share practical solutions for when unstructured documents refuse to cooperate. Expect less theory, more real-world trade-offs, and actionable lessons on building resilient, modern AI pipelines. **From Sprints to Hours: Building an AI-Powered Data Stack at Coolplanet, Niall Magee, Coolplanet** At Coolplanet, we handle massive volumes of customer data effortlessly. But our internal business data? That started with Google Sheets, a basic BI tool, and a quiet confidence that it would scale. It didn't. In this session, we’ll share our honest journey from a fragile spreadsheet setup to a production-grade modern data stack using Fivetran, dbt, and Snowflake. More importantly, we'll reveal how AI became our ultimate force multiplier, turning sprint-long tasks into hours-long workflows. The highlight of the session is a deep dive into our AI-driven build process. We’ll show you how to take a plain-language brief and immediately generate dbt models, semantic layers, and functional Streamlit dashboards. Key Takeaways: * The AI Workflow: Practical steps to accelerate dbt, YAML, and SQL generation. * The Stack Evolution: Honest lessons from migrating to Fivetran, dbt, and Snowflake. * Beyond Traditional BI: Why we are shifting toward AI-scaffolded Streamlit apps. * Snowflake Cortex: How to ground natural language queries in a governed semantic model. **Location** Clayton Hotel Charlemont **Agenda** 6:00 pm – Food & Networking 6:30 pm – Welcome 6:35 pm – Right Story, Right Reader: Building a Hybrid News Recommendation Engine in Snowflake * [Juliana Murphy](https://www.linkedin.com/in/subiuliana/), The Irish Times 7:05 pm – Accelerating Data Engineering with Snowflake Cortex Code * [Jenny Zhou](https://www.linkedin.com/in/yingying-jenny-zhoudong/), Snowflake 7:25 pm – Break 7:35 pm – Extracting Structure from Chaos: Parsing Documents from 400+ Media Sources with Cortex AI at Buymedia * [Estella Roberts](https://www.linkedin.com/in/estellaroberts/), Buymedia 8:05 pm – From Sprints to Hours: Building an AI-Powered Data Stack at Coolplanet * [Niall Magee](https://www.linkedin.com/in/niall-magee/), Coolplanet 8:35 pm onwards – Drinks & Networking

**Power Pages Server Logic: Finally, real backend power** If you’ve built Power Pages portals before, you’ve probably had to juggle JavaScript, Liquid, and Power Automate just to implement what should be simple backend logic. Finally, things are changing, Server-Side Logic introduces a new way to handle business rules, validations, and integrations—securely and in real time—without relying on workarounds. In this session, we’ll break down what this means in practice, when to use it and how it compares to other methods. We’ll also run through a live demo to show how it works end-to-end. bio: **Oliver** **Rodrigues** is a Microsoft Business Application MVP and Power Platform Architect. He’s been working with Portals over the last several years and love to share knowledge and experience with the community. **Prompt to App: Does Copilot Plans Actually Deliver?** In this session, we’ll take a practical look at Copilot Plans in Microsoft Power Apps and see how far it can really go in building apps from a simple prompt. Starting with a real scenario, we’ll generate an app using Copilot, explore what it creates in Microsoft Dataverse, and review where it works well versus where it still needs manual refinement. Expect a live demo, honest observations, and a clear view of whether this is a genuine productivity boost or just a good starting point. **Mohit Chaturvedi** Dynamics 365 and Power Platform Lead at Simply Dynamics ; with 12 years of experience delivering enterprise CRM solutions across sectors including finance, retail, public sector, and manufacturing. Experienced in solution architecture, cloud migrations, and leading cross-functional teams.

Dear Illinois Prairie PUG members, Our next meetup will take place in a **new location**. Please read **the whole announcement** carefully to note all the changes. Our new meeting place is **Chicago Innovations at 1 W. Monroe**. *Talk Title*: pg_lake: Unifying transactional and analytical data with Postgres *Speaker*: Elizabeth Christensen, Snowflake *Talk Description* The data world used to be defined by “transactional" (OLTP) and “analytical” (OLAP) workloads, but we’ve asked ourselves, “Why not both?” A new series of extensions called pg_lake has just been released to connect Postgres to object storage and open table formats - like csv, Parquet, and Iceberg. pg_lake bridges the two worlds of transactional and analytical data for a vendor neutral, open source, unified data stack. This talk will explore the pg_lake extension, including how to build it, and demos of using it with modern data workloads in object storage like Amazon S3. We’ll create simple data pipelines with no ETL and high performance analytics. pg_lake is more than just an extension. It is the foundation to a fully unified data path with 100% open source tools backed by PostgreSQL, DuckDB, Iceberg, and Polaris. *Agenda* 5:20 - doors open 5:30 - pizza arrives 6:00 - 6:10 - Hettie D. Opening remarks 6:10- 6:20 - Hettie D. Data warehouse history overview 6:20 - 6:50 Elizabeth C. pg_lake: Unifying transactional and analytical data with Postgres 6:50 - 7:00 Q&A 7:00 - 7:50 - Open discussion and networking 7:50 - 8:00 - Cleanup time and closing *Notes about our new venue*. I am delighted to have an independent venue for the first time since I am hosting the meetups. I hope that this will be our permanent home. And as you all know, with more freedom comes more responsibilities. You will notice the change in the RSVP form. We are thankful to our hosts and promise to be responsible. We comply with the [PostgreSQL Code of Conduct](https://www.postgresql.org/about/policies/coc/). We do not want to waste food, so please indicate your dietary preferences. We will not close the RSVP in the morning of the meetup, but please do your best to RSVP in advance so that we can order the appropriate amount of food and drinks. Also, all meetups will be hybrid - please don't forget to indicate whether you are attending in-person or virtually. Thank you, and I look forward to seeing you all at our new location!
