Data Science using Python

**Overview** === He's back! For our February event, we are thrilled to welcome a special guest out of semi-retirement: John Ryan. As a former Snowflake employee and current Data Superhero, John has been there since the beginning. In fact, he and I co-hosted Ireland’s first-ever Snowflake event. Since the venue was a converted church, we called it the **"Church of Data."** It was the perfect setting to kick off our Snowflake evangelism. **Abstract** === Moving from on-premises data platforms to cloud isn’t just a technology change — it’s a cost and operating model shift. Many teams underestimate this and end up with performance issues, spiralling spend, or both. This session explains why traditional on-prem thinking breaks down in Snowflake, how Snowflake is designed to scale, and where customers commonly go wrong. Using real lessons from three large Snowflake customers, we’ll walk through: What “scale up” really means in Snowflake (and when not to use it) Three common mistakes that quietly drive cost and poor performance What actually worked in production — not theory, not marketing slides This is a practical, experience-based session aimed at engineers, architects, and technical leaders who want Snowflake to run faster without wasting money.

Join us for an Apache Kafka® x Apache Flink® meetup on Wednesday February 25th from 6:00pm in Dublin hosted by Autodesk! **Venue:** Autodesk 1 Windmill Lane, 2nd Floor, Dublin D02 F206 **PLEASE BRING A FORM OF VALID ID AND REGISTER WITH YOUR DETAILS FOR SECURITY PURPOSES/BUILDING ACCESS. THANK YOU!** **Agenda:** * 6:00pm: Doors open * 6:00pm – 6:30pm: Food, Drinks & Networking * 6:30pm - 7:15pm: John Byrne, Sr. Manager, Partner Applied Solutions, Confluent * 7:15pm - 8:00pm: Rishayah Kumar Trivedi, Senior DevOps/SRE Engineer, Autodesk & Douglas Hobson, Principal DevOps/SRE Engineer, Autodesk * 8:00pm - 9:00pm: Additional Q&A and Networking **First Speaker:** John Byrne, Sr. Manager, Partner Applied Solutions, Confluent **Title of Talk:** Flink State: Design Choices You Can’t Undo *(on Confluent Cloud)* **Abstract:** A practical look at how state behaves when running Flink on Confluent Cloud, the early design decisions teams often underestimate (keyed state, TTLs, upgrades, reprocessing), and the kinds of problems that only show up months later. **Bio:** John Byrne is a Sr. Manager, Partner Applied Solutions at Confluent, the company founded by the original creators of Apache Kafka®. With a strong background in data engineering, John previously worked for Slice, Registers of Scotland, and Sopra Steria, where he specialized in event streaming, ETLs, and data governance. Passionate about GIS, mapping, and ETL processes, he has delivered talks at FOSS4G and developed production-grade ETL projects incorporating spatial data and mapping technologies. In his spare time, John enjoys playing golf and coaching his local youth rugby team. **Second Speakers:** Rishayah Kumar Trivedi, Senior DevOps/SRE Engineer, Autodesk & Douglas Hobson, Principal DevOps/SRE Engineer, Autodesk **Title of Talk:** To Production and Platform: Our Kafka Journey, DR Strategy, and Kafka-as-a-Service **Abstract:** In various organisations, multiple teams have historically had to build Kafka the hard way, spending months on security hardening, compliance validation, observability, and disaster recovery, often repeating the same work with inconsistent outcomes. The result is slow onboarding, duplicated effort, and operational silos that don’t scale as more streaming use cases come online. In this talk, we walk through our Kafka production journey on AWS MSK: how we began with a POC, what it really takes to make Kafka production-ready, and the key platform decisions we had to take to standardise the architecture and operations. We’ll then dive into disaster recovery for streaming applications where the hard problems aren’t just infrastructure failover, but event continuity and restoring pipelines under pressure. We’ll share our HA DR approach for Kafka-backed systems, including an active/passive regional strategy, and practical failover/failback considerations to minimise RPO/RTO. Finally, we’ll close with our Kafka-as-a-Service (KaaS) vision for Autodesk teams: self-service, policy-driven deployments and service tiers that let internal teams onboard in hours instead of months so the product teams can focus on building streaming features, while the platform provides consistent guardrails for security, reliability, and recoverability. Attendees will leave with a checklist of production-ready requirements for Kafka, a clear mental model for DR in streaming systems and a set of platform patterns for evolving towards Kafka-as-a-Service. **Bios:** **Rishayah Kumar Trivedi (Senior DevOps/SRE Engineer, Autodesk)** Rishayah is a Senior DevOps/SRE engineer at Autodesk's data streaming and processing platform team with 9+ years of experience building scalable cloud infrastructure and automating enterprise deployments.

The next Dub\|Sec meetup will take place in the Dublin Workday offices on February 25\, 2026\. Workday are delighted to be hosting this Infosec event in conjunction with Dub\|Sec and the Women in Cybersecurity Community Association \(WICCA\)\. In order to ensure your place on the evening, please sign up through [this link](https://invites.envoy.com/group-invite/TQWwzJ2WyL5lED4D). We'll be there from 6.00pm. Our first speaker will start at around 7pm. **19:00 - Building a digital beehive: The cluster that wasn't real, but the attacks were** by Arnav Tripathy Kubernetes is everywhere now—and so are attacks against it. Misconfigurations, exposed APIs, and overly permissive RBAC have made clusters a prime target, while most security tools stop at scanning images and YAML instead of showing what attackers do after they get in. This talk introduces KubeDecoy – a lightweight, open-source Kubernetes honeypot built from familiar components: vcluster, Falco, Falcosidekick, and NGINX. The goal is simple: stand up a convincing fake cluster, expose realistic attack surfaces, and quietly observe how real adversaries interact with them. **19:40 - OffSec x AI : The Rise of Autonomous Pen-testing Agents** by Manav Bankatwala. As we are witnessing a shift from static security scanners to "Agentic AI", tools that don't just find signatures, but actively reason, plan, and exploit like a human hacker. This talk will explore the current state of AI in offensive security, using the open-source tool Strix as a live case study. If you would like to speak at any future Dub\|Sec\, please email us at [info@dubsec.ie](http://info@dubsec.ie/)! Join us for some drinks, food and general chat about infosec. Everyone is welcome whether you’re a pro, an amateur or just curious about the field!

books! chaos! chats! flinta folkies only, please.

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.*

Dublin Dataviz is delighted to welcome Andy Kirk as our first speaker of 2026! Andy is the founder of [Visualising Data](https://visualisingdata.com/) and works with [clients around the world](https://visualisingdata.com/clients) as a data visualisation design consultant and prolific [trainer](https://www.visualisingdata.com/training/). He is a a four-times published [author](https://www.visualisingdata.com/book/) and host of the ‘[Explore Explain](https://www.visualisingdata.com/podcast/)’ video and podcast series. In his talk, **The 7 Hats of Data Visualisation (Revisited!),** Andy will showcase the value and richness of data visualisation as a key literacy in this contemporary digital age. We all have a stake in this, whether that is through our roles as creators, consumers or coordinators, but it can appear to be a substantial challenge to fully embrace the multi-disciplinarity of this subject, whether as individuals or more generally across organisations. Framed as the ‘7 hats’ of data visualisation, Andy will look back over his 15+ years of experience developing an expertise in this subject to present his view of the major competency ‘ingredients' that make up the all-round talent recipe of a visualiser today. He will differentiate the knowledge required from skills necessary to demonstrate, the attitudinal maturity from the technical intelligence. He will also advise on some of the strategies that will help you continue to develop and refine your data visualisation literacy. Join us for what's going to be an amazing evening, with pints in Arthurs pub surely to follow.

We present a hands-on Demo from the Google Cloud Professional Architecture Exam Learning Path Location: 1 O'Connell Street Lower, North City, Dublin, D01 TX31

In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA

We will show a variety of methods for building agents that run in Microsoft Foundry. This covers the different types of agents: Prompt, Multi, and Hosted, as well as the development lifecycle using evals and traces.
