Have a sweetheart? Celebrate post-Valentine's Day at the Silver Diner! Single? Celebrate post-Valentine's Day at Silver Diner! Located at 1250 Half Street SE in Washington, DC just blocks away from Navy Yard Metro on the Green Line, Silver Diner has something for all tastes, from vegan to omnivore and gluten-free to carnivore! Silver Diner can accommodate a large party without reservations. Checks are separate. NOTE: The Nationals ballpark entrance at M and Half Streets SE is closed. Please exit at the New Jersey Avenue SE entrance. NOTE: Driving is NOT recommended, as parking is expensive and impossible to find. DC is also infamous for getting people lost. I will post Metro service changes next week. HEALTH AND SAFETY DC in February is notorious for having snow, sleet, ice, and freezing rain, sometimes all at once. If any of this happens, I'm rescheduling the event for the following weekend. I am also taking a COVID test on the day of the event. If I test negative and am feeling well, I will be there. If I am sick or test positive, I will stay home. The event will still happen either way. See you soon, Jenny

In a parallel world where everyone has an innate “frequency,” those with high frequencies are gifted, popular, and – most importantly – lucky. People in lower ranges have correspondingly less of these traits but more emotional depth. When someone with extremely high frequency is in close proximity to someone especially low, chaos ensues. A boy and girl at opposite extremes of the scale meet in elementary school and encounter each other repeatedly over many years. While the story seems at first to be a *Romeo and Juliet* variation in search of a happy ending, their universe has some secrets that will make the action weirder and more entertaining than anyone could expect. ■ Title — *Frequencies* ■ A.K.A. — *OXV: The Manual* ■ Director — Darren Paul Fisher ■ Cast — Daniel Fraser, Eleanor Wyld, Owen Pugh ■ Unrated, suitable for teens and adults ■ ©2013 \| 1h 49m \| Mystery\, Romance\, Sci\-Fi ■ Distributed by Samuel Goldwyn Films ■ Licensed for showing in Alexandria libraries by Swank Motion Pictures

**Circlesinging Workshop: Discover Your Musical Voice (90 minutes)** **Register here**! [https://pci.jotform.com/form/260257573283158](https://pci.jotform.com/form/260257573283158) Join members of VoiceExchange on February 22 for an introduction to -- or continued practice of -- the art of collaborative vocal improvisation. In this 90-minute workshop, we'll explore the captivating practice of circlesinging—where voices intertwine to create spontaneous, layered musical landscapes without instruments, written music, or rehearsal. **The Workshop Experience** Standing together in a circle, you'll discover your innate capacity to create music with nothing but your voice. We'll guide you through foundational techniques for developing simple musical patterns that blend with others, creating beautiful moments of shared sound. Through focused instruction and guided practice, you'll experience the unique joy of co-creating improvised vocal music. This workshop draws from practices developed by Bobby McFerrin, Rhiannon, and Música do Círculo, introducing you to the essential elements that make collaborative vocal improvisation both accessible and deeply rewarding. **What You'll Learn** * Basic techniques to unlock your personal capacity for musical invention * How to create simple looped musical ideas that combine with others * Foundational skills including listening techniques and basic vocal layering **Who Should Attend** This workshop welcomes anyone comfortable with their singing voice—particularly those who've found themselves naturally harmonizing with songs on the radio or humming improvised melodies. No formal music training or ability to read sheet music required—just bring your curiosity and willingness to explore. **What You'll Take Away** * **First Steps in Musical Discovery:** Begin to uncover your unique musical voice and capacity for spontaneous creation * **Taste of Community Creation:** Experience the connection that forms when voices unite in collaborative musical conversation * **Introduction to Mindful Listening:** Practice attentive listening and responding through sound **Workshop Details** **Date**: Sunday, February 22, 2026 **Time**: 3:00-4:30 PM **Location**: Elwood Smith Community Center, 601 Harrington Rd, Rockville, MD 20852 **Parking**: Available in lot outside the building **Register here**!

In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA
