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.

[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Torture in the Middle Ages,”** with Larissa “Kat” Tracy, visiting assistant teaching professor of English at the University of Maryland Baltimore County and author or editor of ten books on medieval violence. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-torture-middle-ages](https://events.ticketleap.com/tickets/profsandpints/dc-torture-middle-ages) .] When *Pulp Fiction*’s Marsellus Wallace vows to “get medieval” on someone we assume that they’re in for some serious pain. Torture—that most notorious aspect of medieval culture and society—more recently has been portrayed in popular culture in series like G*ame of Thrones* and *Vikings*, through lurid scenes depicting torture and gruesome punishment as standard medieval practice. In many modern European cities one can find popular museums displaying such gruesome implements as the rack, the strappado, the gridiron, the wheel, and the iron maiden. The dominant mythology suggests that the Middle Ages was a period during which sadistic torment was inflicted on citizens with impunity and without provocation. The truth, however, is a lot more complicated. Join Professor Larissa “Kat” Tracy, who has extensively researched torture, punishment, and social justice in medieval society, for a talk challenging preconceived ideas that popular historians, films, and media have promoted about the prevalence of torture and judicial brutality in medieval society. She’ll discuss medieval Europe’s actual use of torture—the instruments, the laws, the cultural norms, and the victims—and make clear that the act of punishment was actually a very different legal event. She’ll argue that the portrayals of medieval torture in literature represent satire, critique and dissent; they have didactic and political functions in opposing the status quo. The books that Professor Tracy has written or edited include *Torture and Brutality in Medieval Literature*; *Castration and Culture in the Middle Ages*; *Medieval and Early Modern Murder*; *Flaying in the Premodern World*, and most recently *End Game: Exile and Execution in Medieval and Early Modern Society*. When she gets medieval on you it means you are going to learn. The experience, however, won’t be painful at all. (Doors: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.) Image: Torture instruments on display at Prague Castle. Photo by Clayton Tang / Wikimedia Commons.

**REGISTER AT THE LUMA EVENT PAGE!!!** https://luma.com/2e6rhzjo **Agenda:** ​​6:00 - 6:30 PM - Welcome and mingle 6:30- 6:45 PM - Introductions 6:45 - 7:30 PM - Talk 7:30 - 8:00 PM - Wrap up ​​**Description:** ​IAI coding agents can now scaffold entire applications from a single prompt. But for mission-critical systems that require compliance, reliability, and auditability, "it works on my machine" isn't enough. When your agent makes fifty tool calls, rewrites three files, and confidently hallucinates a security vulnerability, how do you even begin to debug that? ​This talk introduces a practical, open-source toolkit for injecting observability, control, and systematic testing into agentic AI development. Using MLflow's tracing and evaluation framework, we'll follow a single throughline: building an AI agent with a coding assistant (Claude Code), tracing both the assistant's work **and** the agent it produces, then evaluating quality with LLM judges - closing the loop from development through production monitoring. ​You'll walk away with a concrete workflow for turning the black box of agentic coding into something you can inspect, measure, and trust. No vendor lock-in required. ​**Speaker Bio:** ​Tim Lortz is an AI Product Specialist at Databricks, where he has worked since 2019. He currently serves as the technical lead for Databricks' go-to-market efforts for AI in regulated industries, focusing particularly on enterprise-grade governance for AI platforms. ​ Prior to Databricks, Tim spent many years in various data science practitioner and leadership roles in the Federal contracting space. He holds a PhD in Industrial & Operations Engineering from the University of Michigan (Go Blue!!) and a BS in Industrial Engineering from the University of Pittsburgh.

Demos of the Voyager platform capabilities and will discussion of a recent State DOT project. **Dr. Aditya Kapoor: Assessment of Inundation Dynamics in Nebraska Using AlphaEarth Foundations** **Embeddings** * This study demonstrates that AlphaEarth Foundation Embeddings (AFE) provide a highly efficient, "analysis-ready" framework for mapping regional surface water inundation without the computational burden of traditional multi-source data fusion. By applying Random Forest classifiers to AFE data across 901 Nebraska lakes from 2017 to 2025, I found that this method outperformed existing products like Dynamic World, which exhibited estimation errors of up to 43.8%. The analysis revealed a critical environmental trend: a mean inundation decline of over 6,600 m² per year, closely mirroring a regional rainfall reduction of 14.18 mm/year. Ultimately, the findings highlight AFE as a scalable tool for identifying hydrological instabilities, particularly in smaller water bodies, offering significant advantages for real-world water resource planning and flood risk assessment.

Whether you've never done improv before, or you've done it for so long you knew Del Close on a personal level, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup** for some fun and games! The idea behind improv is to create entire scenes from scratch based on a suggestion from the audience. This can be done in game form, like *Whose Line Is It Anyway*, *ComedySportz*, or *Wild 'n Out*; it could also be done to tell stories, like *Middleditch and Schwartz*. Our meetup, which is central Ohio's longest running (and free!) weekly comedy event, brings the games (and occasionally different forms) for you to play in a safe, supportive, and compassionate environment. Not only is it a lot of fun, but you get to work on thinking faster on your feet, plus it's an excellent way to meet new people and make friendships that'll last a lifetime! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "Yes, And" that you'll have fun!

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!
