Come and join us on Jun 18, 2026 for a dive into a topic that impacts everyone using Python. (**Important**: The event requires a mandatory registration) Everyone knows that there is no real multithreading in Python - or is there? The tradeoffs between processes and threads is well known. But what if we could have the best of both worlds? This is where subinterpreters come in. We will go over what subinterpreters are, how they work, and most importantly, how we can use them to make our code faster. We will also go deeper into Python’s internals and explore what a GIL-less Python looks like. The “freethreaded” builds of Python are easily accessible - but are there drawbacks? After that, we can have a quick chat and enjoy some drinks and pizza (provided by SiteGround) If this sounds interesting to you, make sure to sign up below: **Speaker bio:** Lyuboslav Karev has 6 years of experience with anything Python related - web development, automation, AI and Machine Learning.

In early May, two of our Atlassian experts packed their bags and flew to California for Atlassian Team '26 - one of the biggest gatherings in the Atlassian ecosystem. Georgi and George spent several intense days in Anaheim, sitting through keynotes, joining partner sessions, hosting conversations, and talking to people from organizations across the world who are wrestling with the same questions we are. They're back now. And we thought the best way to share what they learned is an evening with beer and pizza. So what did they actually bring back? The biggest shift was a fundamental change in how Atlassian is positioning itself - not just as a suite of tools your team uses, but as the layer that makes your organizational knowledge usable by any AI system you're already working with. The data your teams have been building for years in Jira, Confluence, and JSM - the workflows, the ownership, the history - is now something external tools can actually access and act on.  On the AI side, Rovo moved well beyond being a smart assistant. The new direction is about AI that takes on real work: breaking down complex requests, executing multi-step tasks, and doing it in a way that stays visible and auditable. Non-technical people can now build automations by describing what they need in plain language. Engineers can ask questions across entire multi-repo codebases. And for the first time, organizations will be able to see exactly where their AI investment is going - and whether it's actually connected to anything strategic. Join us for an informal evening where we unpack all of it and what it means for the way we work.  Agenda --- Speakers Georgi Gachev - Nemetschek Bulgaria (Team Lead) Gogo is a software developer for almost 15 years and he had experience with all kinds of technologies including Java, .NET, Android, Javascript, Python and more.

I specialize in building high-performing teams, and bridging the gap between business goals and tech execution. My mission is simple: I help systems and people work better — starting with myself, and never stopping at “good enough.” I thrive where complexity meets urgency — whether it's redesigning inefficient workflows, elevating engineering culture, or aligning delivery with long-term value. I bring a strong foundation in internal auditing practices, ensuring that systems are not only efficient but also aligned with key compliance and quality standards like ISO 27001 and ISO 9001 — without losing sight of the human side of work. I’ve also developed a strong interest in artificial intelligence — not just as a tool, but as a transformational force. I’m exploring how AI can enhance quality, automate the right parts of work, and help us build more adaptive, intelligent systems that serve both business and society responsibly. I believe the future of tech depends not just on innovation, but on responsibility, empathy, and structure that serves both people and planet.

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.

Please join members of the Fairlington Social Club on Saturday June 20, 2026 from 3:30 PM until 7:00 PM for the Shirlington Village "Yacht Party." We will meet on the patio of Samuel Beckett's Irish Gastro Pub to enjoy dinner & drinks and enjoy the music performed by the band "Got Yacht?" performed in front of the Shirlington Library. The Shirlington Village "Yacht Party" event will feature live music and entertainment, arts and crafts, and food & drink on the closed off streets of Shirlington Village. Admission is free. The Village at Shirlington is a "Sip and Stroll" property, meaning you can carry to-go alcohol beverages purchased from restaurants as you take in the sights and sounds of the block party on Campbell Ave. Free parking available in any of the five parking garages or the surface lot located in Shirlington. Look for the six foot long Fairlington Social Club banner in order to find the group.

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.

Join the Jaycees in volunteering at the Arlington Food Assistance Center (AFAC)! We sort donated canned goods or bag portions of dry goods or produce for AFAC's weekly food distributions to low-income families in Arlington. AFAC is a long-time community partner of the Arlington Jaycees! At 2:30, or when we are done at AFAC, we will head to **Guapos** in nearby Shirlington for food and drinks. So that we can appropriately plan the tasks to do for the right number of volunteers, **PLEASE UPDATE YOUR RSVP** as soon as possible whether or not you are able to attend. We have to limit the number of volunteers due to limited space at AFAC, and don't want spots to be taken by people who sign up but don't show up. AFAC is located at 2708 South Nelson Street and Four Mile Run Drive. There is street parking available near the building although parking spots are limited. The Volunteer Entrance is the GRAY DOOR by the loading dock. Volunteers must wear closed-toe shoes (no sandals or flip-flops) and must have your hair covered while bagging food. You can bring a hat from home or AFAC will provide disposable hairnets. The Arlington Jaycees (part of Junior Chamber International) is the premier nonprofit in Arlington that provides young people (ages 21-40) with opportunities for personal & professional growth, business networking, community involvement and social engagement in the Arlington Community and worldwide. Our mission is **leadership development through community service**. Check out our website [www.arljaycees.org](https://arljaycees.org/) to learn more and to become a member of this amazing organization!
