Join us for dinner at **Rotana Grill**, at Temple Bar. To secure your spot, a _€3 deposit is required_ when signing up and being added to the attend list. Without the deposit, you’ll be placed on the waiting list. [Secure my spot](https://revolut.me/aphidethp) [Rotana Grill](https://www.instagram.com/rotanagrilldublin?igsh=OWlzeG43dmg0d2g2) This event is free to attend, but please note the following: • Due to an increasing number of no-shows, last minute RSVP and the fact that some restaurants require a deposit for reservations, a deposit will now be required via [Revolut](https://revolut.me/aphidethp). It will be deducted from your bill. Please note that the deposit is non-refundable. • The restaurant will apply a service fee for groups, typically around 1%. • Each participant is responsible for paying for their own food and drinks. • Some restaurants may not split the bill, so to keep things smooth and hassle-free, it’s a good idea to bring some cash or have Revolut ready for easy payments. • If a restaurant requires a booking fee, we may need to consider alternative venues to ensure a seamless experience for everyone. • RSVP updates are essential: If you can no longer attend, please update your RSVP so others on the waiting list can join. This also helps us manage reservations more effectively.

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.

Is the recession really coming — or is it just ghosting us? Is it slowly creeping in, or will it never fully arrive? And where is the drop in housing prices we’ve all been waiting for? In this session, we’ll explore these questions and more as we try to make sense of the post-COVID economic landscape: uncertainty, resilience, inflation fatigue, and what might actually lie ahead. This event will be co-hosted by Cillian, who will help guide the discussion and bring expert perspective to a topic that affects all of us, whether we like it or not. Looking forward to having you join us for what promises to be a thoughtful and lively conversation.

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 a **CNN** model to classify images into categories, we will be using a public dataset. Together, we will walk through the full pipeline from data preprocessing to model training and evaluation. You will receive a jupyter notebook with reusable code showing all of these steps. No set up required, just a laptop and a google email address :) **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 lounge 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.*

**Google Analytics Alternatives** Is it finally time to make the switch away from Google Analytics? Two-and-a-half years ago Jason Packer asked this question at Columbus Web Analytics Wednesday. Since then: Google’s Universal Analytics has been sunset, we’ve changed our name to Columbus Data & Analytics Wednesday, and Jason has released two editions of his book “Google Analytics Alternatives”. Fresh off the release of the 2nd edition of his book, we thought it was time to re-open this conversation. While people love to complain about it, GA’s market share has remained relatively constant (at least in the United States). Why is that? You won’t find any complaints about GA4 in this talk, but rather an overview of what’s currently available in the market and how to frame your decision-making process. We’ll also be giving out some free copies of Jason’s book! So even if you’ve got a “GA4Lyfe” tattoo (no judgement), there’s free books to go with the free pizza and beer. Thanks to our 2026 sponsors: [Clarivoy](https://www.clarivoy.com), [What Box Consulting Group](https://www.whatboxconsultinggroup.com), [Conductrics](https://www.conductrics.com), and [Piwik PRO](https://piwik.pro) More info at [cbusdaw.com](https://cbusdaw.com)

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.
