Numerical Analysis

We are delighted to collaborate with [Dublin C++](https://www.meetup.com/cppdug/) this month. We have one talk and it's about Python and [Blender](https://www.blender.org/)! We will be upstairs in Anseo. The talk will be followed by Q&A, a chance for you to follow up with the speaker, and for both communities to chat and exchange stories and experiences. **TALK DETAILS** **Title:** Python + Blender: Automating Creative Workflows by Carlos Alexandre **Description:** (15 mins + Q&A) This talk walks through the workflow of a computer graphics project, covering its main stages: fundamentals, modeling, lighting, materials, texturing, and rendering. We’ll explore how Python can be used inside Blender to automate parts of the modeling process, helping reduce repetitive tasks and improve efficiency across the pipeline. The session demonstrates how scripting can support procedural modeling, and scalable workflows, connecting creative production with technical automation. The talk is suitable for beginners and intermediate users interested in computer graphics, Blender, or Python, and no advanced scripting experience is required. ** THANKS** **Community Partners:** * [Coding Grace](https://codinggrace.com/) * [PSF](https://www.python.org/psf/): Meetup * [PyLadies](https://pyladies.com/) **FAQ** Note that all our events are 18s+. **Q.

**PLEASE NOTE NEW START TIME 7 PM** Beauty is hard to deny while watching olympic skaters twirling acrobatically on the ice. Or meeting a newborn for the first time, or appreciating some stunning aspect of nature. But what about those experiences makes them beautiful? And what makes certain scenes, actions or events ugly? And why don't we all agree what's beautiful or ugly? Join us at Walters Cafe in Dun Laoghaire this Tuesday and bring your views with you; buy and drink at the bar and engage meaningfully with others in a civil discourse on beauty and ugliness.

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

**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.

Yoga Classes with Hannah Fitzpatrick on Wednesday evenings at Anam Ashram, Tallaght, 7pm-8:8.30pm. This is a moderate paced class where we will stretch and strengthen our bodies in various ways, but we will also keep a keen awareness on our breath and body-sensation throughout. We'll aim to increase our connection and our compassion to ourselves, while also giving our bodies the refreshing and rejuvenating workout it adores and requires! We will end with a guided deep relaxation. Contact Hannah for more details and for booking on 083-4863900

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.*

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.

**Caller: Frank Buschelmann** **Band: The Rosenthorns** **Big Scioty Contra Dance** **temporarily returning to our long ago location for Jan-March - First Congregational Church, 444 E. Broad St., Columbus 43215** WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing! Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor. Be sure to come for the beginner's lesson from 7:30 - 8:00, followed by dancing 8:00 - 10:30. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner. Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot. For more information contact me or check out our website: [www.bigscioty.com](http://www.bigscioty.com/) Please bring your own refillable water bottle. Snacks to share are always welcome!
