Knowledge Sharing

📚 Do you love reading, but wish you had a structure and a community to share your insights with? Join our small circle of curious minds (just 4 members per gathering) as we come together for an hour of focused reading—in the calm setting of a library or the cozy atmosphere of a café. Here’s how it works: First part: Quiet reading on your own—bring a book you’re exploring, whether it’s philosophy, history, psychology, literature, or anything meaningful to you. Second part: We regroup and each person shares key takeaways, insights, or questions sparked by their reading. This sparks a structured yet free-flowing conversation around ideas, perspectives, and personal reflections. Why join? Add structure to your reading habit. Discover new books, authors, and ideas through others’ choices. Build real connections by sharing and listening deeply. Socialize around something meaningful instead of small talk.

**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

Step into an immersive journey with the Kuntanawa from the Amazon of Acre, Brazil as we share the ancient ancestral stories, songs, and wisdom of the Amazon rainforest and its people. Guided by Prince Haru and Dr. Hayra Kuntanawa, this gathering is an invitation to connect with the living spirit of the forest and deepen your relationship with the natural world. Spaces are limited for these intimate gatherings and are being offered on sliding scale donations. We hope to host this song circle by the fire at Real Eyes, weather permitting, or will be indoor if weather does not permit. This is an amazing way to directly support an indigenous tribe in the Amazon that is actively serving as guardian and protector of the land and her peoples. Every $44 donated plants a tree in the Amazon and supports its care for three years.

**Looking for Players New And Old:** Hi y'all, I'm Andrew. I'm looking to jumpstart an Old-School Renaissance (OSR) TTRPG group in the Greenbelt/College Park area. No experience is necessary. Our first session will be a level 1 one-shot designed by me. In it, players investigate a stone tower on behalf of an army looking to occupy the surrounding lands. For those with limited experience with the OSR or Shadowdark, take a look bellow. I'm excited to see you guys there and get this thing rolling! **Shadowdark, Our Old-School Style Rule System:** Shadowdark is a system designed to bring together the principles of early D&D gameplay and the familiar and intuitive nature of modern systems. Those of you familiar with D&D and Pathfinder will find the six attribute/D20 roll-over system familiar, however, the way the game is played is fundamentally different in a few ways: * **Character Survival Not Guaranteed:** In some games, the DM works to ensure characters don't die easily or without a good reason. In Shadowdark, danger lurks in every corner and characters can die at any time depending on how they react to their environment. If they want their characters to survive, players must play carefully, avoiding traps and sneaking past enemies too powerful for them. The more hardcore style of gameplay encourages players to consider their risk management strategy and to develop creative solutions to avoid a perilous fate. * **Player Smarts Over Dice Rolls:** Yes, you'll still roll to see if you can push the door down or cast a spell, but you won't be rolling as many perception checks to search for traps or distract guards as in other games. Players are encouraged to play smart and communicate what they are doing in detail. "I run my hands along the face of the wall, checking to see if there are any strange indents or hidden buttons" is a lot more interesting than "I check for hidden doors, I rolled a 15" * **Rules-Light:** This game is simpler than D&D and Pathfinder in terms of how many rules there are. This opens things up for more creativity in our actions while still giving us a bounded ruleset to keep things fair and interesting.

Hands-on learn how to save life & limb, when mired in the wilderness of an urban disaster zone, travel or rural area far from hospital, or natural area miles from an access point, during the critical minutes or hours before ambulance arrival. Come away with actual do-it-yourself care-giving skill and confidence, and 2-year SOLO certification. Counts as WFR Recertification, too. No prerequisites. YOUR SPOT IS NOT RESERVED UNTIL YOU'VE COMPLETELY REGISTERED AT WWW.SOLOWFA.COM \***Spaces are limited. REGISTER: www.solowfa.com or 434.326.4697** Can't make these dates? Check out more course locations and dates on our website. WHO: Open to the general public, adults & teens with solid attention spans. Know your loved ones are safe wherever they are. WHY: Mired in a disaster zone, travel or rural area far from a hospital, or natural area miles from an access point ... accidents, destructive weather, and terrorism happen, and all-too-often members of a group are not capable of dealing with the emergency. This leads to improper care of the patient, and endangers the entire group. Many recreational accidents are preventable, and improper care of trauma can compound even simple injuries. Very few first aid programs actually address the issues of providing emergency care in a setting where 911 is overwhelmed or not immediately reachable. In this course, classroom instruction and Q&A are interwoven with practical work and problem-solving exercises. Hands-on experience - a most powerful learning tool - during scenarios comprise \~50% of class. TIMING: This is a 2-day class, Saturday and Sunday, 8:00am -7pm each day. Fee: $295 (Earlybird)

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
