Hi everyone, I hope you're well! With this month's Meetup rescheduled to the last Friday of the month, we’re on time for the release of this well-reviewed and promising thriller and will go to see it in the Lighthouse Cinema in Smithfield. TWO PROSECUTORS @8:30pm at the Lighthouse Cinema. Screen 4 (117mins) Seating is unallocated so do buy your tickets early - it’s a smaller cinema. [TWO PROSECUTORS | Official UK & IRE Trailer | In Cinemas 27 March](https://youtu.be/rzYfw1M9qT4) *“TWO PROSECUTORS is a haunting portrait of Stalinist Russia, wherein thousands of letters from falsely accused detainees are burned in a jail cell. Against all odds, one of them lands on the desk of a local prosecutor, who takes it upon himself to seek justice for the prisoner.”* There are many reviews online and here are a few: [https://www.filmireland.net/cannes-review-two-prosecutors/](https://www.filmireland.net/cannes-review-two-prosecutors/) [https://www.timeout.com/movies/two-prosecutors-review-2026](https://www.timeout.com/movies/two-prosecutors-review-2026) **Dinner beforehand:** I’ll book a table for dinner at Oscars Bar next door at 6:30pm. If you wish to join us for dinner, please post a Comment to be included in the numbers. Numbers are limited. *Dining:* Note that they do not split bills there so it’s CASH ONLY again for this one, and there’s a 10% service charge on large table bookings.

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 build an end‑to‑end object detection workflow using the **DETR** model from Meta AI, powered by **Hugging Face Transformers** and **PyTorch** based on a Hugging Face tutorial. We will use a small public dataset, walk through data preprocessing, fine‑tuning the model, evaluating performance, and finally running inference on a **new, unseen image** containing a similar object 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.** **For more information about the tutorials:** * The tutorials are interactive and will be conducted using **Jupyter notebooks** on **Google Colaboratory** (a free, cloud-based platform that lets us write and run code directly in the browser). While **Google Colaboratory** is free to use, tasks that require more computational power (such as training deep learning models) may benefit from GPU access. In that case, Google offers a once-off payment for around €10 which can last several months depending on your usage. Some familiarity with **Python** or other programming languages is helpful but not required. Everyone is welcome to join and learn at their own pace. * The tutorial lasts for 1.5 hours. * During the tutorial, I share the Jupyter notebook with participants so they can keep it for future reference. We go through the notebook step by step together and I do my best to answer any questions along the way. * The notebook includes the complete code from data preparation to model training and evaluation. It can be reused or adapted for your own business needs or personal projects * We will be working with a variety of **Python** libraries including **Scikit-learn**, **PyTorch**, **TensorFlow**, **Keras**, **Seaborn**, **Pandas** and **Matplotlib** and the **Hugging Face** framework. These tools will help us explore different machine learning and deep learning techniques using publicly available datasets. * Each tutorial focuses on a different algorithm in depth. Topics covered include **linear regression**, **logistic regression**, **K-means clustering**, **decision trees**, **artificial neural networks (ANNs)**, **convolutional neural networks (CNNs)** for image classification, **object detection** and **natural language processing**. The goal is to break down each technique step by step, making it approachable and practical for real-world applications. 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 **4.30 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.*

Due to an increase of the meetup app costs, it will be appreciated any donation at this link: revolut.me/manuelo38g Are looking for friends? Do you wanna have fun in Dublin? Do you want to chit chat and relax? ... Here you are, this is where to join on Saturday night. We have not a usual location where to meet, we like to go in all the pubs and clubs in town... So, stay tuned for the location. At the end, we also plan the after meetup location where to enjoy the rest of the night. See you all soon.

📚Reading books and discussing them are two distinct experiences! Conversations about books and sharing insights help us better appreciate literature and enrich our lives. Let's grab a drink (alcoholic or non-alcoholic) and discuss books we're currently reading or have recently enjoyed—whether poetry, fiction, or non-fiction. Bring your physical book or e-reader. There's no formal structure or agenda—just books and good conversation.💬 It's a perfect place to get book recommendations and rediscover your reading momentum if you've hit a slump. We welcome readers of all backgrounds and interests! ⚠️**Something Happened?** If something unpleasant happened to you, it may happen to others. Even if it seems minor, don't hesitate to reach out to me. 🔍 **How to find us?** * When I reach the venue, I'll leave a comment in the meetup where the group is seated. Normally, the booking is in my name, so you can ask the staff for the group. * If you're unable to find us, leave a comment in the meetup page. I'll be able to guide you. We highly encourage you to move between tables and strike up conversations with fellow book lovers. These discussions about literature and reading recommendations are often the highlight of the event! As an organizer, I'm always looking for feedback about the event and suggestions for new events, so feel free to suggest ideas to me. 💡 I look forward to seeing you all! 😊

This group is all about hosting a monthly in-person book club right here in Dublin City! If you're into the book we're reading and want to chat about it with others, this is the perfect spot for you. We'll meet for about 1-2 hours, enjoy some drinks and/or food, and dive into the book of the month—sharing our thoughts, exploring themes, and swapping recommendations for future reads. We suggest a €2 voluntary contribution per person to help cover MeetUp fees (cash or Revolut works). See you there!

MEET NEW FRIENDS. The film has been described as the Romeo and Juliet of Ukraine. The film is in Ukrainian with English subtitles. A rare chance to witness Ukrainian theatre and the bonus of meeting some new friends in the process. We will be meeting at the Sean O' Casey Community Centre at 11:30. Screening starts at 12:00. Please book your tickets here https://www.eventbrite.ie/e/lighthouse-cinema-club-shadows-of-forgotten-ancestors-tickets-1985230008396?aff=ebdsshother&utm_share_source=listing_android&sg=40adcc4547b52b74b73b98c1d2da5d51d8e349d56c80b0af84af779a5c8427319164257fa55bc93f8981029d1d14687a9937d8b2ef0744e61dd354c341f084e2b2650cb7be458444b9fa7020d4

We will try to secure a table downstairs in the venue in order to keep the location consistent. New people who know nothing about Linux are welcome and encouraged to attend, please don't be shy. If you are new please feel free to approach one of the organisers, and we'd be only happy to help explain things as best as we can, we honestly don't mind and don't judge. We were new once ourselves :) Please note that in general, these are adult friendly meetups, therefore, we are not responsible for those under 18 in attendance. We may have events targeted at children in the future. As with any Meetup, please try to stick to your RSVP or change it to No if you can't come.

Join us for an engaging panel discussion on **AI Agentic Coding** and how autonomous AI systems are transforming the way software is built. Experts in AI, software engineering, and developer tools will share insights on how agentic AI—systems that can plan, reason, and execute coding tasks—is reshaping modern development workflows. The discussion will cover topics such as AI-assisted development, productivity gains, challenges around reliability and governance, and what the future of software engineering may look like with AI agents as collaborators. Whether you’re a developer, tech leader, or AI enthusiast, this session is a great opportunity to learn, ask questions, and explore how agentic AI is redefining coding

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

This meeting will be a discussion of the book "the Science of Aliens" by Mark Brake

Central Ohio Radio Enthusiasts—CORE—is an informal community for anyone enthusiastic or curious about radio—whether you're new to radio and want to learn or you've been tinkering for years and want to share. Ham radio operators, GMRS users, Meshtastic fans, software-defined radio nerds, makers, and technical and non-technical folks are all welcome. No experience required or expected. This month we have **WiFi HaLow: Introduction and Practical Use** with **Alex Barbur**. Details are are [core.radio](https://core.radio).

**The Data-Driven Brand: Using Analytics to Shape Perception** Can you use analytics to improve tacos? This being CBUSDAW, we think the answer is probably “yes”, but we’re not sure how to implement or test this theory. For our April meetup we’ve got Sara Kear, CMO of Condado Tacos, to investigate this delicious question. Sara will explore how she blends quantitative data and qualitative customer feedback to shape brand positioning and drive business decisions. We all know that marketing and analytics go way beyond attribution. Sara will show how Condado uses customer insights to inform product and pricing strategy. She’ll also highlight how Condado leverages customer feedback at scale to influence operational priorities, positioning marketing as the voice of the customer across the organization. In the last 12 years Condado has gone from one location in Columbus to 52 locations across 10 states, so we’re guessing there’s more to that growth than really good guac (though the guac probably helps). Ultimately, this talk focuses on the intersection of art and science—using data to inform creativity and build a brand that resonates with customers in a measurable way. **About Our Speaker** Sara Kear is Chief Marketing Officer at Condado Tacos, where she oversees brand, restaurant design, menu and pricing strategy, off-premise including catering, and customer data strategy. Since joining in 2021, she has helped grow the brand from 19 to 52 locations while building a data-driven marketing organization focused on loyalty and customer insights. Condado has since been named to the Inc. 5000, recognized as Breakout Retailer by Chain Store Age, and consistently ranked among FastCasual’s Top 100 Movers & Shakers.
