There will be 3 presentations about topics in functional programming and time for questions as well as free discussion. Please contact Pekka (pekka.kaitaniemi@metosin.fi) if you'd like to give a presentation about a topic that interests you! Talks: **Using Go & Clojure with Babashka pods to create Conjtest (Ilmo Raunio)** Explores a Policy as Code tool built using Clojure/Babashka, bridging it to Golang using the Babashka pod protocol. Conjtest allows you to write and evaluate tests against common configuration file formats (such as EDN, YAML, or Terraform) using Clojure. **How I created my first RISC-V processor with Clash (Mika Tammi)** **Mu-Nu pairing (Kari Pahula)** A look into a novel layered program architecture that pairs two different ways of representing code: a finite, arrow-based tree structure (μ) for analyzing and optimizing program logic, and a and a productive, infinite monadic state-machine (ν) for the actual execution. The talk focuses on its practical uses and demonstrations. Tentative schedule: 17:15 doors open, free social activity 17:30 welcome words from Metosin 17:40 talks and Q&A 19:30 free social activity

Welcome to join our Sahaja Yoga meditation meetings in English! The meetings are free of charge and you can just show up. The group consists of people of different ages and nationalities who have been meditating different periods of time. Newcomers are welcome at any time. We normally sit on chairs or on pillows on the floor, so there is no need to bring a mat and you can wear normal clothes. Meditation means mental silence or thoughtless awareness. You are present here and now, but your mind is not bombarded by thoughts from the past or the future. In this state, you feel peace and joy, which are the essential elements of the present moment. With regular practice of meditation, it is possible to establish this state within us. The group is lead by volunteers who are experienced and can offer guidance to get you started. We give a short introduction to the meditation and after that we do meditation exercises. We also give tips on how to meditate at home. After the meditation class, we have a cup of tea and there is time for questions. Welcome! We hope to see you in our meditation meetings!

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

Each class in this series has an attendance fee. 3. Each class, from BOTH a sign-up and fee perspective, is a separate entity. 4. As the Etch toolset evolves, so too will the class outline below. **Introduction:** Our Site Building with Etch class provides detailed instructions on the philosophy of the Etch development framework, as well as in-depth, hands-on instruction on using the Etch environment and associated tools. Anyone familiar with Kevin Geary and the Digital Gravy set of products will tell you that they offer ground-breaking approaches to professional WordPress site development. As we write this, the Etch toolset and environment are rapidly taking shape, with weekly quantum leaps forward in WordPress development methodologies. As early investors in the Etch product offering and its development process, we are actively testing and evaluating the toolset as it takes shape. We are beyond excited to see how WordPress site development is being modernized, and can't wait to bring this course set to you. It will be a paradigm shift in page and site development within WordPress, as well as moving your development mindset light-years forward. Join us as we explore Etch and dive deep into development approaches that will genuinely elevate your craft as a website developer and agency provider. Scalable, responsive, compliant websites are now within easy reach, and Etch provides both the platform and toolset to take you there. **The breakdown of the 10-class series is as follows:** * Class 01 - TBD * Class 02 - TBD * Class 03 - TBD * Class 04 - TBD * Class 05 - TBD * Class 06 - TBD * Class 07 - TBD * Class 08 - TBD * Class 09 - TBD * Class 10 - TBD Throughout the class sessions listed above, we cover the following key areas of web development with Etch: * **Introduction to Etch Interface:** * Familiarization with the toolset's layout and understanding how to navigate and interact with its various components. * **Visual Site Building:** * Techniques for creating layouts using Etch's interface, incorporating sections, divs, containers, and elements to build semantically correct page structures. * **Styling and Design:** * Utilizing Etch's styling approach to customize elements, apply global CSS classes for consistent design, and leverage features like Flexbox and CSS Grid for responsive layouts. * **Dynamic Content and Custom Fields:** * Integrating dynamic content from custom post types and custom field plugins (like ACF, Meta Box, and even built-in fields) to build data-driven websites. * **Component Building:** * Creating and managing reusable components for headers, footers, post type layouts, and other site-wide elements. * **Performance Optimization:** * Understanding how Etch contributes to fast-loading websites and implementing performance best practices. * **Advanced Features:** * Depending on the class level, it might delve into advanced topics such as conditional logic, interactions, and custom code integration to enable more complex functionality.
