Dallas is best known for oil, cattle, Neiman Marcus and the Cowboys--not mass transit. But Dallas Area Rapid Transit (DART) provides light rail, "Trinity Railway Express", regional rail, bus routes, GoLink on-demand service, and paratransit over a 13-city territory. TEDC member Katy Kelly will provide an overview of DART's offerings and explore the challenges of providing transit in a Sunbelt community. We'll also have a preview of our next transit outing! Hope you can all make it :-)

Come the whole time or if you just spend 30 minutes. All are welcome. You are welcome and encouraged to bring your own coloring supplies but, if you don't have any, I will have plenty and am happy to share! (coloring books, colored pencils, and markers). Part of the mission of this group is to provide us an opportunity to check out AND SUPPORT local businesses. So, please don't bring any outside food/drinks and, while purchasing something isn't at all a REQUIREMENT to participate in the event, I do strongly encourage you to try something from the vendor :) I look forward to seeing and meeting you there! ***\*\*DISCLAIMER*\*\*** Photos may be taken during the event to be shared here on Meetup so feel free to let me know if you'd like to be excluded from them.

**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.

The conversation course is continuing education, designed to excel students' Amharic conversation skill. 2. The course runs for 12 weeks. 3. We don't give placement test. The students place themselves and they can switch to a level up or down, after they examine themselves. 4. Class cancelled due to 'Force Majeure', will be recovered at the end of the course. 5. Arriving by Metro: The closest metro stations are Farragut West and Farragut North. 6. Meter parking is also an option. It is about $ 0.25 for 8 minutes. 7. The payment for each class is $ 15.00 per person per hour. It will be $ 20.00 per person per hour for walk-ins. However, it is depending on availability. 8. Students can bring friends and pay $ 20 for 2 persons per hour. But it has to be an advance payment.

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.

An open space for real conversation about how technology is shaping our world, and how we can respond with wisdom, purpose, and values. ## COMING UP: ## Life with Augmented Intelligence **Shaping how we live, work, and build in an AI-driven world** From assistants → to collaboration → to autonomous systems *** **A different way of thinking, working, building.** Most people are still using AI at the surface. Answers. Shortcuts. Quick help. But underneath, work is starting to look different: * systems instead of tasks * collaboration instead of commands * design instead of effort This is a space to step into that. Not a workshop. Not a panel. A place to see what’s emerging, hear how others are thinking, and explore what it means for your own life and work. *** ## Tech & Truth Café 📍 Greencourt Innovation Center 🗓️ May 10 & 17 🕐 1:30 – 5:00 PM 1:30 → arrive and connect 2:00 → ideas and conversation 3:00 → demos and exploration 4:30 → wrap up *** **WHO:** If you’ve been experimenting with something interesting, building something, or thinking differently about AI… reach out. We’d love to include you in the conversation. *** **Bring a laptop.** *** For people who feel like: “there’s more to this than what I’m currently doing with AI.” **Come be part of it.** **WHO** **For people who feel like:** "There's more to this than what I'm currently doing with AI." Come be part of it. **WHAT TO EXPECT**

**IMPORTANT! Please register on [Luma page](https://luma.com/klm98cuc)** *Ignore the displayed time — it’s 5:30pm VA time.* AI is making us faster than ever — and at the same time, quietly questioning our place at work. ​We’re all feeling it: tools that boost output in minutes, automate entire workflows, and sometimes… do the job better. So where does that leave the human? ​This conversation dives straight into that tension — no sugarcoating, no generic optimism. Just real perspectives from people working inside the shift. ​ **Speakers:** [Nina Borysova, MBA ](https://www.linkedin.com/in/nborysova/?utm_source=luma)**Director, Product Management Technical (PMT), Data Analytics and AI Solutions, Mastercard** **​**[Dr. Volodymyr Tkach ](https://www.linkedin.com/in/volodymyr-tkach/?utm_source=luma) CEO \| Ph\.D\, Associate Professor \| MIT Research Fellow \| Cybersecurity\, Threat Intelligence\, Anomaly Detection\, Artificial **​We’ll unpack:** ​– where AI actually boosts productivity vs. where it replaces thinking ​– which roles are evolving — and which are quietly disappearing ​– how teams are restructuring around AI (and what that means for individuals) ​– how to stay valuable when execution becomes automated ​– what “creative work” even means when AI can generate ideas on demand ​– the psychological side: anxiety, denial, adaptation ​If you’re feeling both excited *and* uneasy about AI — you’re not alone. And you probably shouldn’t ignore either feeling. ​Come for clarity. Leave with a more honest map of what’s ahead.

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!
