**Come Sing With the Fairfax Jubil-Aires!** Do you enjoy singing along to your favorite songs? Curious what it’s like to sing rich four-part harmony with a friendly group? Come visit the weekly rehearsal of the Fairfax Jubil-Aires and see what barbershop singing is all about! The Fairfax Jubil-Aires are a welcoming mixed a cappella chorus that performs classic and contemporary barbershop harmony. Our members come from all kinds of musical backgrounds—some have years of experience, while others simply love to sing. What we all share is a passion for music, laughter, and community. Visitors are always welcome at our weekly rehearsals. You can sit back and observe, or jump right in and sing with us—no pressure either way. You don’t need to read music, and there’s no audition required just to visit. We rehearse **Wednesday evenings at 7:00 PM in Fairfax**, and we’d love to have you stop by and check it out.

Important: Register on [AICamp website](https://www.aicamp.ai/event/eventdetails/W2026061814) is required for admission. **Description:** Welcome to the AI meetup in Washington DC. Join us for deep dive tech talks on AI, GenAI, LLMs and Agents, hands-on experiences on code labs, workshops, and networking with speakers and fellow developers. **Agenda:** \* 5:30pm\~6:00pm: Checkin, Food/drink and networking \* 6:00pm\~8:00pm: Tech talks and Q&A \* 8:00pm: Happy Hour at Courthouse Social (cross the street) **Tech Talk: Secure Developer Environments in the Age of AI Agents** **Speaker:** Patrick Brown (Coder) **Abstract:** Federal engineering teams are under pressure to ship faster while meeting some of the most demanding security and compliance requirements in the world. In this talk, Patrick Brown of Coder explores how cloud development environments (CDEs) give agencies a foundation to accelerate software delivery without sacrificing control — and why that foundation matters even more as AI-powered coding agents enter the workflow. He'll cover how CDEs keep source code off endpoints, enforce zero-trust access patterns, and provide the consistent, ephemeral infrastructure that both human developers and AI agents need to operate safely at scale. **Speakers:** Stay tuned as we are updating speakers and schedules. If you have a keen interest in speaking to our community, we invite you to submit topics for consideration: [Submit Topics](https://forms.gle/JkMt91CZRtoJBSFUA) **Sponsors:** We are actively seeking sponsors to support AI developers community. Whether it is by offering venue spaces, providing food, or cash sponsorship. Sponsors will not only speak at the meetups, receive prominent recognition, but also gain exposure to our extensive membership base of 5,000+ AI developers in D.C and 500K+ worldwide.

A dark paranormal/ fantasy romance from bestselling author, Sadie Kincaid. Every few millennia, a child is born. Some say they're marked with a curse. Others claim they possess the power of the ages. Meet Ophelia Hart. Lover of classic literature and unicorns. An orphan with nobody in her corner—no family, no friends. But it's her loneliness that fuels her life's ambition to become a social worker and help the forgotten children just like her. For a foster kid with only slightly above-average grades, it feels like a pipe dream. Except it seems that someone is looking out for Ophelia after all. When an unexpected opportunity to attend Montridge University arises, she thinks her life is finally taking a turn for the better. Too bad she comes to the attention of the three ruthless, arrogant commanders of the Ruby Dragon Society. Three of the most feared and powerful vampires on campus. But Ophelia doesn't believe in vampires. Or in witches, or magic, or ancient prophecies. Until she has no choice. Little does she know, she's about to have her whole world turned upside down. Because there is something about Ophelia Hart. Something that captures not only the attention of the Ruby Dragon commanders, but also their powerful, enigmatic sire-Professor Alexandros Drakos. With no idea of the power running through her veins, Ophelia must learn to trust the very men whom all others fear. And she needs to do it fast, for there are darker forces at work than those at Montridge University. Forces that were long ago Forged in Blood. Forged in Blood is book one in a trilogy. Books 1 and 2 end on cliffhangers and book 3 is a HEA.

Join us for another session of our study group as we cover the book Build a Reasoning Model (from Scatch).
