Read & Reflect: A Social Reading Circle.
Shared Pages, Shared Insights.
📚 Do you love reading, but wish you had a structure and a community to share your insights with?
Join our small circle of curious minds (just 4 members per gathering) as we come together for an hour of focused reading—in the calm setting of a library or the cozy atmosphere of a café.
Here’s how it works:
First part: Quiet reading on your own—bring a book you’re exploring, whether it’s philosophy, history, psychology, literature, or anything meaningful to you.
Second part: We regroup and each person shares key takeaways, insights, or questions sparked by their reading. This sparks a structured yet free-flowing conversation around ideas, perspectives, and personal reflections.
Why join?
Add structure to your reading habit.
Discover new books, authors, and ideas through others’ choices.
Build real connections by sharing and listening deeply.
Socialize around something meaningful instead of small talk.

Herndon Tennis Refugees: 8:30 AM @ Dominion HS
Join us for our weekly Herndon Tennis Refugees meetup! We’re a drama-free doubles crew for experienced, competitive players (USTA high 3.0–4.0). Come rally, connect, and have fun. No line-call drama or cutthroat battles. Fair play is the baseline.
When the old Meetup vanished like a botched overhead, we were stranded like tennis orphans. So we made something better: scrappier, smarter, and shockingly organized. We turned chaos into kick serves and awkward goodbyes into solid backhands. If you’re returning—welcome home. If you’re new—nice upgrade.
**The rundown:**
* We start with 2 courts (8 players).
* If full, **join the Waitlist**—at 12 RSVPs, we add a 3rd court; at 16, a 4th.
* Rotating doubles. Friendly, flexible, and fun.
* Events open Sundays at 8 am and fill fast.
* Frequent late cancellations (within 36 hrs) are discouraged. We may ask you to find a sub or limit your future participation.
The old group left us at the baseline. Now? We’re charging the net. 🎾
Gonzo's Nose (reunion) @ FNL!!!
**Gonzo's Nose is the most popular party band in the national capitol area. Formed in the summer of 1996 by four musicians from the College of William and Mary, Gonzo's Nose brings solid musicianship to a massive setlist of cover songs, which range from the early 80's up until songs that hit the radio just yesterday.**
**We will meet by the beer tent.**
The End of Human-Scale AppSec
For decades, application security has been built around a simple assumption: humans are the primary producers of software. We train developers, review their pull requests, model threats in design meetings, and build controls around human decision-making. That assumption is rapidly breaking down.
As AI coding assistants evolve into autonomous software agents, organizations will gain access to an effectively unlimited engineering workforce capable of producing software at a speed no human team can match. The pressure to adopt these systems will be driven not by curiosity, but by competition. Companies that successfully harness agentic development will ship faster, iterate faster, and potentially outpace those that do not.
This shift forces a fundamental rethinking of application security. The future of AppSec is not securing developers—it is governing an agentic workforce. Threat modeling, code review, security testing, and change management will not disappear, but they will need to operate at machine speed and increasingly be performed by systems rather than people. In this talk, Ken Johnson, CTO of DryRun Security, explores what the next decade of application security may look like, the assumptions that will no longer hold, and why security professionals must understand these systems deeply if they hope to influence the future rather than react to it.

NOVA Code & Coffee [165] - At FCED Venue
NOVA Code and Coffee is an inclusive, informal, co-working session. People of all skill levels are invited. The concept is simple, bring a laptop and ideas, we'll provide the coffee and donuts! Here's how it works:
1. At 10:15 everyone introduces themselves and briefly describes what brought them to Code & Coffee today (project, homework, networking, etc)
2. For the rest of the day, folks work in the communal space on their projects providing one another help and conversation as needed. Oh and they usually drink coffee and tea too!
That's it! Hope to see you there!
**Location**
Our hosts are the Fairfax City Economic Development
Building: [10300 Eaton Pl, Fairfax, VA 22030](https://www.bing.com/ck/a?!&&p=d7298231ca2df594df822003f9a93517c788fceefe1fcbb79c8976696e341bc6JmltdHM9MTc1MzIyODgwMA&ptn=3&ver=2&hsh=4&fclid=180d0745-3b7f-69a1-23a2-11433a7868e5&u=a1L21hcHM_Jm1lcGk9MTA5fn5Ub3BPZlBhZ2V-QWRkcmVzc19MaW5rJnR5PTE4JnE9RmFpcmZheCUyMENpdHklMjBFY29ub21pYyUyMERldmVsb3BtZW50JnNzPXlwaWQuWU44NzN4ODI4MTk2Mjg0NTk5MDM4MTU0MiZwcG9pcz0zOC44NjE0NDYzODA2MTUyMzRfLTc3LjMwMjE3NzQyOTE5OTIyX0ZhaXJmYXglMjBDaXR5JTIwRWNvbm9taWMlMjBEZXZlbG9wbWVudF9ZTjg3M3g4MjgxOTYyODQ1OTkwMzgxNTQyfiZjcD0zOC44NjE0NDZ-LTc3LjMwMjE3NyZ2PTImc1Y9MSZGT1JNPU1QU1JQTA&ntb=1)
Conference Room A- Large, Floor 1
This is a new venue for us, so give us some time to get more details about it.
Driving is the best option. There is plenty of free on-site parking. Otherwise, we are a 22 minute bus from the Vienna Metro Station. Bicycling from Vienna is possible but difficult, though once you are here, there's a bike rack in the garage behind the building, and there's also a Capital Bikeshare dock 15 min walk away.

AI Meetup (June): Secure AI Agents
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:**

**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.
