Yoga Therapy: Wake-Up Yoga
This class is designed to target those places in the body that might need a little extra space breathed into them after a night's sleep. This morning, get your blood pumping and work out all the stiffness, cramping, and tightness that are often left in the body after hours of laying still. Now seize the day!
**Please reserve your spot at www.piesfitnessyoga.com**. The session is offered both InStudio and OnLine. The Zoom link for the OnLine session will be emailed 15 minutes before class starts to those who are registered at www.piesfitnessyoga.com. **Sign up for sessions must be made at least 2 hours prior to class.**
The address is 1322 Prince St Alexandria, VA 22314.
Our entrance is located on the side of the building, parallel to West St. **Street parking is available and additional parking is located at Shiloh Baptist church, spaces 3,5,7,9.** The church is located across the street from the studio, on the corner of Duke St. and West St.
Yoga Therapy: Stretch, Destress & Restore
Hit the pause button for an hour and reduce your stress. You will be compassionately guided through an exploration of intentionally linking your breath with the movement of both dynamic and static stretching and its impact on your (P)hysical, (I)ntellectual, (E)motional, and (S)piritual layers. Then experience the calming practice of restorative yoga which was designed specifically to move you from the fight, flight, or freeze state of the nervous system into the rest and digest state. Leave this all levels, accessible class feeling restored, renewed, and ready for what life has in store for you next.
**Please reserve your spot at www.piesfitnessyoga.com.** The session is offered InStudio only. **Sign up for sessions must be made at least 2 hours prior to class.**

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)

**Important Notice:**
I have seen an increased number of signups and no shows amongst brand new accounts. In an effort to make sure we have room for everyone if this is your first time joining and you have just created a meetup account please reach out to me via Meetup or discord.
**Late Policy:**
RSVPing will hold your spot for up to 10 minutes after 6. If you expect you may be running late please reach out to me via the store's discord. My username is iluvbacon610.

Bitcoin Book Club: The Fourth Turning
Join the Bitcoin District Book Club! We meet every month to explore new and exciting rabbit holes by reading books that are popular with bitcoiners.
Join us for a deep dive into *The Fourth Turning: An American Prophecy* by William Strauss and Neil Howe. In this session, we’ll explore one of the most influential modern frameworks for understanding historical cycles and generational change—and why its predictions seem increasingly relevant today.
Strauss and Howe propose that history moves in recurring cycles, or “turnings,” each lasting roughly 20–25 years and shaped by generational archetypes. According to their model, societies pass through four phases: a High, an Awakening, an Unraveling, and finally a Crisis—the “Fourth Turning.” This final phase is marked by institutional breakdown, social upheaval, and a restructuring of the political and economic order. We’ll discuss where we might currently sit within this cycle, how past Fourth Turnings (like the Great Depression and World War II era) unfolded, and what this framework suggests about the coming decade.
For those interested in macro trends, generational dynamics, and long-term historical patterns, this book offers a provocative lens for interpreting today’s instability—and what may come next.
Buy the book on [Amazon](https://a.co/d/0dNwKse5)
**Event Notes:**
* Discussion Starters: We’ll kick things off with a few key questions around generational cycles and crisis periods, but feel free to bring your own perspectives.
* Future Reads: Let us know if you have recommendations for future book club selections! We’ll add them to the list posted [on our website](https://bitcoindistrict.org/bookclub).
* Afterwards: Feel free to join us at Pubkey after the meeting to hang out, continue the conversation, and grab some food!
**Getting There:**
* 🔴🟢🟡 Gallery Place/Chinatown + 2 min walk
* Parking: Street & garage parking available nearby

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.
**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

**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.
