**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

Free flat-fix classes!! On the last Tuesday of each month, we host fix-a-flat classes! Bring your bike with you if you'd like to learn by using your own bike. We will cover basic flat fixes with an inner tube. We may be able to answer a few questions about tubeless, but the focus will be flat fixes for inner tubes.

There is supposed to be a let up in the seemingly incessant rain. Let’s take advantage with a walk at Brookside Gardens. We will meet to the right of the visitors center. If anyone is interested we can go to lunch afterwards.

++++++++++++++++++++++++ **Our 4th Tuesday of the month Euchre Location:** Hank's Oyster Bar (Second Floor) 818 N St Asaph St Alexandria, VA 22314 [https://hanksoysterbar.com/](https://hanksoysterbar.com/) GPS: [https://maps.app.goo.gl/9c4JVfapgdM1P31w7](https://maps.app.goo.gl/9c4JVfapgdM1P31w7) **Free Retail Parking Around the Corner.** **(Elevator takes you to St. Asaph Street)** Colonial Parking 530 First St. Alexandria, VA 22314 [https://www.ecolonial.com/park-with-us/parking-locator](https://www.ecolonial.com/park-with-us/parking-locator/?detail=1&loc=en&id=1703) ++++++++++++++++++++++++ * **Second Floor Opens @ 6:00pm (Gary will be there).** * **Please arrive by 6:30pm.** * **Please don't leave before 8:30pm.** * **Hank's Oyster Bar closes at 9:00pm.** * We are on the second floor, accessible via the stairs or elevator from the downstairs restaurant. Restrooms are also on this floor. * We start play as soon as we have enough people to get a table going. * We will be getting our bills at 8:30pm so we are all settled by the 9:00pm(ish) closing time. ++++++++++++++++++++++++ **For those new or haven't been in awhile, here is some basic information about our meetup:** 1. **Know How to Play the Game**: Every member of the Alexandria Euchre Club must know how to play the game of Euchre to attend a meetup. If you know the game, but it has been years since you've played, that is fine as we've all been there and will be patient while it comes flooding back to you. 2. **New To The Group:** If you have never been, we are a friendly group and welcome everyone to come. Very few people come with a friend or spouse. What this means is that it will not be awkward to arrive alone. It is better than a happy hour because it is easy to make conversation about cards. You don't have to even ask the dreaded "what do you do?" question. If you come three times, you are a regular. Also, house rules are that we play stick the dealer (ask if you don't know this variation). 3. **Correct Table Count:** Euchre is a 4 person game--yes, I know there are 3 and 6 person variations, but most people prefer the 4 person game. What this means is that if you sign-up, we are counting on you to be there. The deadline for RSVP is 2 days prior to the meet-up. Please update by that time, especially if you are going to cancel your RSVP. If you get 3 "no shows" and you'll only be able to sign up via an organizer. 4. **The Waiting List:** If this month is like the previous months, we will have a waiting list. Please be considerate and honor your RSVP. Of course, if you are sick and on death's door we don't want you to come out and get the rest of us sick; however, if not please do come play. A good evening of food, drink, cards, and friendship may be all that you need to be more productive the next day. If you are on the waiting list I am expecting you to either remove yourself if you don't want to be considered for an open slot, or check the site (or email) so you know you've been promoted to an RSVP of YES when a slot opens up. 5. **Costs:** There are some costs associated with meetup -- I have to pay Meetup every 6 months for listing on their website. They don't work off of advertising fees. We pass the bowl around and ask people to throw a $1 in each time they come. Thanks everyone... looking forward to seeing ya !!

**FOR BEGINNERS** If you've ever seen Korean movies or shows, you may have seen characters play with small red cards decorated with flowers and animals. Those cards are called "hwatu" or flower cards. The most popular game played with hwatu is "Go-Stop". Come to this next Hwatu Hangout (Iris Edition!), and learn how to play Go-Stop. It can take some time to orient yourself with the cards and rules, but once you do, there's no turning back. It's major fun. **FOR EXPERIENCED PLAYERS** No Tazza-style deck rigging and, most importantly, *no gambling*. We will play with plastic chips to raise the faux stakes, but that's it! If you'd like to skip the lesson/demo, then please arrive at 2p for game play. \*\*\* **ETIQUETTE** Please update your RSVP at least 48 hours before the event to ensure that those on the waitlist have a chance to come. It's the nice thing to do! **FOR REGULARS** Thanks for coming back! Please email/DM me if you are planning to come.

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

Sometimes it’s a massive advantage… and sometimes it can complicate your business if you don’t know what you’re walking into. In this training, we’ll cut through the “agents vs investors” drama and focus on one thing: **what makes you more money and gives you more leverage**. You’ll learn: * **When being licensed helps investors win** (better access, better data, better terms, better deal flow) * How investors use a license to **create extra profit centers** (commissions, referrals, listings, buyer rep, property management pathways) * The truth about **MLS access, pocket listings, and being first to the good deals** * How licensing impacts **wholesaling, double-closing, assignments, and disclosures** * What brokerages don’t tell you: **fees, splits, compliance, and time requirements** * When it’s smarter to **partner with an agent** instead of becoming one * A simple decision framework: **licensed vs partnered vs hybrid model** You’ll walk out knowing whether licensing fits your goals—and if it does, the cleanest path to do it without slowing down your investing.

Most people use AI like a search box: they type one sentence, hope for the best, and get frustrated when the answer is generic, wrong, or useless. But getting better results from tools like ChatGPT, Claude, Gemini, and other AI systems is not about memorizing magic prompts. It is about learning how to give the AI better context. In this beginner-friendly session, we’ll break down how to make AI dramatically more useful by improving the way you communicate with it. You’ll learn how to give clearer instructions, provide examples, set constraints, ask for better output formats, and use follow-up questions to turn a mediocre answer into a genuinely useful one. We’ll cover practical techniques you can use immediately for work, learning, writing, coding, planning, research, and everyday problem solving. We’ll also touch on why these same ideas show up in more advanced AI systems, including RAG, agents, evaluations, and AI workflows. No technical background required. Bring your curiosity, your questions, and maybe one real task you wish AI was better at helping you with. **What you’ll learn:** * Why “better prompting” is really about better context * How to structure requests so AI gives more useful answers * How to use examples, constraints, and output formats * How to iterate when the first answer is not good enough * How these skills connect to more advanced AI workflows This meetup is for anyone who wants to move beyond basic ChatGPT usage and start getting more practical value out of AI. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
