Monday Morning Courthouse Run/Walk - 40 Min
On Monday, we'll meet in front of the Courthouse Library, 2100 Clarendon Blvd, and head towards the Arlington Cemetery and Memorial Bridge.
Notes:
If you're not familiar with the area, please review the routes. If it's cold, take cover inside the foyer area of 2100 Clarendon Blvd.
Routes:
We'll run 20 minutes out and then turn around and run 20 minutes back to Courthouse. Everyone runs at his/her own pace, so the distance will depend on your speed.
1. Courthouse Library > N Rhodes St. Bridge > Arlington Blvd > N Meade St. > Iwo Jima/Marine Corps Mem > Arlington Cemetery > Memorial Bridge. Depending on your preferred pace, you may turn around at any point on the route.
Pace:
All paces are welcome! We'll be doing an out and back route, so everyone will turn around at the halfway time marker. That way we should all start and end at the same time.
Free Parking at Courthouse Plaza:
The underground garage is on Clarendon Blvd btwn Wayne and Veitch Sts. (near Strayer/CVS and the AMC Theater). If the first 2 levels on the left are full, you can park on the lower levels to the right. Street and Surface Parking lots should be free in the area as well.
Metro:
Orange or Silver line to Courthouse Station.
Note: Photos taken during the event may end up on Instagram, Meetup, Strava and similar platforms.
Vintage Cube at Your Hobby Place - Old Town Alexandria
**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.
The list can be seen here: [https://cubecobra.com/cube/list/proxybacon](https://cubecobra.com/cube/list/proxybacon)

Your Evals Are Bad: Evaluation and the Model Development Lifecycle
**REGISTER AT THE LUMA EVENT PAGE!!!**
https://luma.com/27ja5gwl
Join us for an exciting talk by Mary Gibbs, Senior Applied Scientist at Relativity.
â
â**âAgenda:**
ââ6:00 - 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
**ââDescription:**
âIf 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 didnât 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.
**âSpeaker Bio:**
âMary 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

Real Connection-Real Theology
**Real connection with fellow Catholics who are eager to grow in Faith and friendship!** This 3 year--- 45min deep dive into the Catholic faith is a great way to spend your Sunday rest day.
When you are ready to dig deeper and live the faith more fully this is an optimal opportunity. Talk yourself into this!
You may start whenever and can come as often or as little as you desire.
Coffee is served w/ small donation.
It is taught by the priest and/or OCIA director at St Louis Parish who are ALL fabulous- faithful educators filled with theologically inspired knowledge.
You can ask questions at the end, which I love.
It is just a wonderful experience to grow.
Afterwards if you wish, you can also find your way over to the Little Way Cafe Coffee shop across the parking lot to stay for more community time or read some of the excellent books that line the shelves throughout.
If you are new to the community of Alexandria and want to meet like minded folks or a veteran of it, this is a special and unique opportunity and did I mention it is free? :) Hard to believe!

Prompting Is Not Magic: How to Give AI Better Context
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, weâll break down how to make AI dramatically more useful by improving the way you communicate with it. Youâll 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.
Weâll cover practical techniques you can use immediately for work, learning, writing, coding, planning, research, and everyday problem solving. Weâll 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 youâll learn:**
* Why âbetter promptingâ 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.
Ensuring Software Quality in the world of AI Developers - Matt Eland
**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you.
The building address is 4450 Bridge Park
The entrance is 6620 Mooney St, Suite 400
You will need to scan your ID at the door to get a visitor badge.
**Abstract**
Like it or not, AI agents are now capable of turning a quickly written paragraph of requirements into a pull request that is ready to be integrated into real-world production applications and it's now our responsibility to make sure AI doesn't go rogue and take down prod - or corrupt our data by misunderstanding the requirements or our existing schemas. 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.
