Session Abstract ### Data Cleansing using Data Bricks Machine Learning is highly dependent on adequate data. Not only does quantity matter, but more importantly quality. In this session we’ll cover how to build a custom automated process using Data Bricks. This will provide methods for cleaning data in a data lake using functions in Azure. \*Please note, that we will be using Microsoft Teams for the online portion of this meeting. You may want to join a few minutes early to ensure you do not have any issues. If you are attending in person, there are large TVs at the office, and you do not need to bring a laptop or use Teams.

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 **Radio Signal Analysis Using SDRs and OpenWebRX+** with **Scott McCrory**. Details are are [core.radio](https://core.radio/).

Spec-driven development flips the traditional workflow on its head: instead of code being the source of truth, the specification becomes the backbone of design, collaboration, and delivery. 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.

**PLEASE READ THE FOLLOWING IMPORTANT NOTES:** 1. The dates for this series are simply placeholders at the moment. We are working on our 2026 schedule, and adjustments are forthcoming. 2. 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.
