**REGISTER AT THE LUMA EVENT PAGE!!!** https://luma.com/27ja5gwl Join us for an exciting talk by Mary Gibbs, Senior Applied Scientist at Relativity. ​ ​**​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:** ​If you have ever shipped a model, watched your metrics improve, and later learned from your users that something was wrong, the metrics were always wrong. You just didn’t know it yet. An evaluation consists of three components, a benchmark, a scorer, and a claim about what a score represents. Each component has its own weaknesses. Benchmarks can suffer from narrow coverage, contamination, or saturation. Scorers are often chosen for ease of automation or computation rather than for their alignment with user outcomes. And the claim connecting a score to reality is rarely made explicit. These gaps compound across the model development lifecycle. When metrics improve, teams treat that as a signal and optimize directly against it, which is how a measurement problem becomes a model problem. This talk maps where evaluations can go wrong, considers counterarguments, and ends with practical advice for building better ones. **​Speaker Bio:** ​Mary is a Senior Applied Scientist at Relativity, tackling data science challenges in the e-discovery and legal tech space. She is also an organizer for Women and Gender eXpansive Coders DC (formerly Women Who Code DC), fostering a community dedicated to empowering women and nonbinary individuals to excel in their careers. Mary's experience spans various domains. She has developed data science solutions related to job search and career progression at Teal, cybersecurity challenges at LiveAction Software, and commercial and government consulting at Mosaic Data Science. Before venturing into the field of data science, Mary conducted and published research pertaining to the cellular and molecular mechanisms underlying neurodevelopment at the National Institutes of Health. In other words, she has dissected and imaged a lot of fruit fly brains. She holds a M.S. in Data Science from The George Washington University and a B.A. in Biological Sciences from Cornell University

GM Jason will run an Ultraviolet Grasslands session. Stay with me, here: what would happen if we mashed up Oregon Trail with Dying Earth with Mad Max? Well, UVG answers that question (that nobody ever asked) with this heavy metal psychedelic fantascience pointcrawl game. Please the horned catlords by hitching your lime green fox-ocerous pony to your wagon and heading west to see if you can’t trade all this vampire wine for some profit! None of those words will make any more sense to you after playing, probably, but we’ll have an amazing time exploring! This will be way more about the joy of exploration, the tedium of travel, and the thrill of commerce than it will be about battle. If that sounds refreshing, come try something new with us! If you’d like to try to roll up a new character, DM the DM and I’ll get you instructions. New players welcome! No prep needed! **Where**: 1111 Belle Pre Way, Alexandria. Right across the laneway from Lost Dog. Looking for a place to play in-person RPGs and make new friends? Burnt out on internet D&D?

From Dungeons & Dragons to sci-fi sagas, there's something for everyone here. Join us for regularly scheduled meetups, make new friends, and unleash your imagination in a fun and collaborative setting. Let the games begin! **Rules**: always teachable at the table **Gaming is for everybody**: Welcoming, inclusive, and safe **Pregens**: the GM will have pre-made characters so you can jump right in **Game**: Old School & New School, but likely lightweight **Multiple GMs**: We run games in a rotating GM format, so come to play and make friends, but we'll be looking for your interesting one-to-three shots to try.

NOTE: This working session is at Lamond-Riggs Library not MLK. It is near the Fort Totten Metro Station. A game development **Working Session** involves 3 key parts: 1. Tell people what you're going to do 2. Actually do stuff 3. Show people what you did **What to bring**: Laptop, Charger, maybe a power strip if you have one handy, any other game development tools you need. Try to download any software you need before the working session. There is Wifi at this location, but it may be slow if you have to download any large files.

In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** TBD
