**NEW UPDATE:** Additional members of the cubing community have reached out to me and we all agree, the more cubing the better! I have removed the 12 person limit and we are adding an overflow cube for those also interested in non vintage type cubes! These guest cubes may consist of the following: \- Alex's Enchantment Cube: [Enchanted to Meet You](https://cubecobra.com/cube/list/enchantedCube)! \- Matthew's Avatar cube: [Avatar: The Last Airbender Power(ful) Cube](https://cubecobra.com/cube/list/avatarTLA) Priority will still fall to firing the vintage cube but what this means is if we reach 12 members we can offer the option to fire both cubes at 6 and 6 or just the vintage cube at 2 pods each. If we reach over 12 we will divide up the players between the two cubes with earlier RSVPs getting priority on their choice. If you have a cube that you are interested in having as a spill over cube please reach out to me and we can coordinate. Thank you! Come join and casually draft a vintage cube that is open to everyone. No cost to enter! The store provides promo booster packs and I usually throw in a pack of the most recent standard set to award to the people with the best records at the end of the night. [What is Cube?](https://www.youtube.com/watch?v=rNDBTRG6keM) What: Vintage Cube Draft When: 6:00pm Where: Your Hobby Place in Old Town Alexandria (Your Hobby Place, 700 N Washington St, Alexandria, VA 22314) We aim to start drafting shortly after 6:00pm as the store's register closes at 9:00pm. The store owner is kind enough to keep the space open for us to finish rounds. In previous events we've usually wrapped up around 9:45. All skill levels are welcome and all cards, lands, tokens needed are provided so you only need to bring yourself and potentially some dice and playmat if you prefer.

**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

\-\-\-\-\-\- [REGISTER FOR THE EVENT HERE (ON LUMA)!](https://luma.com/be8kjf6n) \-\-\-\-\-\- Join us for an evening of collaborative problem-solving as we work on a variety of civic tech projects together. Project needs vary but often include brainstorming, researching, writing, coding, or analyzing data. Check out [our website](https://www.civictechdc.org/projects) for a list of projects which may make an appearance! Meet other civic tech enthusiasts. Learn new skills. Contribute to a project to improve a local civic issue. **All are welcome and collaboration is encouraged.** Laptops are recommended but not required. **Where do I register?** To better serve our growing community, we’re transitioning our event registrations to [Luma](https://luma.com/civic-tech-dc)! **We still love Meetup** Meetup has been an incredible platform for us to build and connect with our community. We’ll continue sharing upcoming events there so that new people can find us, but [Luma](https://luma.com/civic-tech-dc) will be our primary registration platform moving forward. **Why we're making the switch** Meetup’s registration system has some limitations, and we need more flexibility to manage sign-ups and engagement. \-\-\-\-\-\- [REGISTER FOR THE EVENT HERE (ON LUMA)!](https://luma.com/be8kjf6n) \-\-\-\-\-\-

**\*TO ATTEND REGISTER AT - [https://www.socialevents123.com/event-details.aspx?id=13390#tix](https://www.socialevents123.com/event-details.aspx?id=13390#tix)** Cost: $15- $20 depending on how early you register. (\*Multiple Meetup groups are co-organizing so RSVP's shown are just a small % attending. ABOUT: Do you know more than 6th Graders! Here is your opportunity to have some fun playing our Live interactive trivia game (Categories will be History, English/literature, Geography, Science, Math, Potpori). HOW IT WORKS: You can attend via a computer & Webcam or Smartphone/Ipad/Tablet. This completely online event will be LIVE and you will be able to see and hear the other participants while playing. In addition you get to meet and interact with other participants. At game time, your host will read off Trivia questions. Your goal is to come up with the right answer to each question and write it down on your paper. Once the round is over (about 6 questions), we will go through the answers and determine who had the highest score for the round. They will get a raffle ticket for a chance to win a prize at the end of the event. We will have multiple rounds of play and have a system to also virtually introduce you to other participants. HOW DO YOU FIND THE VIRTUAL ROOM: After you purchase your ticket, you will get a confirmation with the zoom link ON DAY OF THE EVENT.

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
