What is Qt?

meet at Tysons Corner Mall Upper Level Food Court

Location: Origin Coffee Lab & Kitchen at the 1101 S Joyce St B33, Arlington, VA 22202. (Not sure why the default address in the map is different). Low pressure way to connect over coffee and have real conversations, whether personal or professional. Everything is flexible. I'm new as a Meetup organizer. Just reach out and we can find a time and place that works better.

​This meetup is for anyone building with OpenClaw (& Claude Code) or experimenting with other AI tools to create agents that can act and make decisions on their own. If you haven’t tried these yet, come hang out, ask questions, and see what others are building. We’ll trade notes, troubleshoot setups, and explore what it takes to run these systems openly on the web instead of inside closed platforms. Bring your laptop, grab some power, and jump into a night that feels part LAN party, part live build session, where people test ideas and show what their agents can actually do. 👉 [RSVP on LUMA](https://luma.com/53dx7no1) We’ll also have some fun by running a live test to see if a few of our agents can send Bitcoin back and forth and talk about why that’s a meaningful step for autonomous AI. It’s a chance to connect the dots between open AI tools, Bitcoin, and the wider goal of creating technology that no one can turn off. 👉 [RSVP on LUMA](https://luma.com/53dx7no1)

**NEW GAME LOCATION at The Board Room** Let's play board games. Not the ones your ancestors played but the really cool ones of the new millennium. We play everything from fun, social games to light to heavy strategy games. Don't know how to play? Not a problem - we're happy to teach. It's a great chance to learn new games or play your favorites with non-competitive people who like to laugh. You can build a railroad, eradicate a plague, or explore the far reaches of the galaxy in one evening. While many will bring their own games, you can show up gameless and still play. We play at the Board Room in Clarendon on Wednesday from 6:30-10:00. It's within walking distance from the Clarendon metro. **Find us in the far left by the fermentation tanks.** If that area is reserved for a private event, look for us in the middle. Look for a group that has containers and carrying bags with multiple games. We're very fortunate to have this great venue for our game nights and they take care of us for 3-1/2 hours, so please spend a minimum of $10 on food or drink and tip generously (at the very least $2, even if 20% of your bill would be $1). Thanks!

Have you seen the movie “**The AI Doc**: Or How I Became an Apocaloptimist” and are left with questions and thoughts that you're longing to express? A group of friends went to see this documentary and couldn’t stop thinking or discussing about it. Now we want to hear from more people who have seen the movie! Come share your thoughts about AI and the world. **NOT from a technological perspective but where our future lies ahead**. We will start from the key **questions** asked in the documentary, including but not limited to: \- Is it the worst or best time to be born now\, at the age of AI? \- Are you an apocaloptimist or pessimist? \- Did anything in the film challenge your previous beliefs about AI? \- Do you think AI will reduce or worsen inequality? \- What can we\, as the general public\, do to ensure AI safety? 💡Disclaimer: We aim to create a thoughtful, open, and respectful space for sharing ideas. You may encounter perspectives that differ from your own—and that’s part of what makes these conversations meaningful. Sometimes, it’s through contrasting viewpoints that the most interesting insights emerge. We encourage everyone to listen with curiosity and engage with respect. 📍We'll be meeting at a cafe near Dupont Circle. Location will be confirmed later this week, depending on the number of attendees.

Title: Potential Applications of Negative Radiation Pressure in Astronomy, Medicine and 2WQC Date: April 19 2026 10:00 am - Noon EDT (16:00 - 18:00 CET) Abstract: While we are used to heating and pushing with light, there is also optical cooling and pulling. I will talk about negative radiation pressure, potential ways to generate it, and its novel applications, like non-ionizing medical scanners, 2WQC (two-way quantum computers) in theory solving NP problems, also potential astronomical sources and their observation. Speaker: Dr Jarek Duda is an assistant professor at Jagiellonian University. He holds degrees in computer science (PhD), mathematics (MSc) and physics (PhD). He is mainly focused on physics foundations, information theory, statistical analysis, and is known for introduction of asymmetric numeral systems.

Welcoming back Kecia Deveney for our annual Creative Minds Summit! This mixed media journal is a place for fragments. For what was saved without knowing why. For scraps, thoughts, images, and moments that did not ask to be finished. Nothing here needs to make sense. Nothing here needs to be useful. These pages are allowed to change, to be returned to, or left behind. This book belongs to the act of keeping. In **A Place for Fragments**, you’ll learn how to create a soft, fabric-covered journal using scraps and remnants using cardboard as our substrate; simple, forgiving binding and stitching methods; ways to layer paper and fabric without planning or pressure; how to let materials guide decisions instead of rules; how to work intuitively and trust when something feels complete enough; simple ways to work on inside pages and making an image focal point using resin. Learn more about this class, your student supply kit fee & list via Artistic Artifacts’ secure online website: [https://artisticartifacts.com/products/cms-place-for-fragments-with-kecia-deveney](https://artisticartifacts.com/products/cms-place-for-fragments-with-kecia-deveney) \*\*\* Due to the size or other requirements of the class or concurrent scheduling, some classes are in our second-floor space: access is via stairs only.

We will be playing two games of Concordia with up 5 players each. All experience levels welcome. Expect the game teach to start promptly within the first 10 minutes. Concordia is a strategy game of economic development set in Roman times. Guide a roman dynasty. Send out colonists to settle down in cities producing bricks, food, tools, wine and cloth. Develop your trade network. Appease the ancient fods for their favor. Players choose their actions in Concordia through playing and acquiring new action cards. Find [here](https://www.youtube.com/watch?v=YkKX8RxPN5Q&pp=ygUVaG93IHRvIHBsYXkgY29uY29yZGlh) a how to play video on youtube.

We'll come together to talk about writing custom apps. Macoy Madson will show how he applied Handmade principles to creating a custom CAD application for a manufacturing company. He will go over the various features and his criteria for what he picked to build vs buy, as well as lessons learned from the shortcomings of his choices. If we have time, we'll also look at compiling native code to WebAssembly. **Agenda:** \- 2pm \- 3pm: Custom app presentation and WebAssembly \- 3pm \- 4pm: Open\-ended discussions\, presentations\, etc\. \- 4pm \- whenever: We'll go get food nearby\! **What we do** Presentations on lower-level, foundational programming topics, ethical software, knowledge sharing, mentoring, and discussion. **Who we are:** We are all about handmade software. Rather than focus on frameworks, heavy abstractions, and buzzwords - we typically create projects or research topics that build an understanding of foundational computing concepts, essential data structures, and hardware/software interaction. **What to bring?** Bring a laptop, project, or just a curious mind. If you're not sure you're ready to contribute, don't worry: we're all here to share our passions and hone our craft. **If you arrive late:** Please enter the room quietly as to not disrupt anyone that is presenting. You can take any empty seat.

Calling all gamers, developers, and video game enthusiasts! Dive into the vibrant world of indie games and play unique creations by talented local developers. Whether you're a seasoned gamer, an aspiring developer, or just curious about the indie scene, this is your chance to connect, play, and celebrate DC’s gaming community. **PARKING INFO**: Parking around this area is expensive ($15-20) and a bit annoying. However the library is right outside Gallery Place metro station. I would highly recommend taking the metro, or driving to a metro station, parking there, and then take the metro in. Location: MLK Library Basement Floor

Title: Foundations of Localized Symmetry Mathematics Date: April 18 2026 Noon - 14:00 EST Summary: The moment you use Euclid’s definitions of points and distances in any of your mathematical axioms, all that follows is assured to produce some level of nonsensical results when applied to the foundations of physics. The reason is not complicated: Euclid’s definitions are deeply mired in accepting as a “given” the very concepts that emerge only in well-defined inertial frames, which in turn are local instances of symmetries that are always finite and context dependent. In this talk, Terry will discuss how reframing mathematics in terms of symmetries that, as in the real world, are finite, composite, and dependent on self-observation (acceleration), results in a richer and far stranger set of mathematics in absolute conservation of quantum numbers generate local and global symmetries — the opposite of Noether’s theorem — that in turn create the emergent classical phenomenal such a particles, fields, space, and time. Speaker: Terry Bollinger is a computer scientist with BS, MS, and professional degrees from the Missouri University of Science and Technology.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you.

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD

Feeling down? Sometimes depressed? Can't focus? Negativity & stress? Recent losses? Creativity in career and personal life hindered by mental blocks? Sometimes we never fully recover from traumatic experiences. Whether it was yesterday, last week or a year ago, traumatic experiences - a loss of a loved one, losing a job, a breakup - can leave you scarred. You talk about it and feel a little better, but it never goes away. After you hang up the phone, it's still there; the sadness, the cloud, the over-thinking, the worry, the guilt. You try to focus, but you're blocked. You try to look forward into new experiences, new relationships but a cloud is hanging over you, casting a shadow on what you once considered a bright, cheerful future. What happened to your courage? Your strength of character? You're 'why not' attitude? Whoever said 'time heals' must have had a special time machine, because after weeks, months, years, you're wondering - when exactly does that kick in? Sometimes it seems like drinking or drugs are the way to go. But they wear off, and now the problem is still there with added side effects from the drugs. At this free local Meetup event we will talk about: * What causes grief, anxiety and depression to become chronic. * Is it possible to regain your joy and happiness even after traumatic experiences? * How to break away from negativity and focus on the future * What are the steps to take to get control of your mind and your emotions? Learn about a safe, gentle, do-it-yourself counseling that can be done in the comfort of your own home. Let's explore safe, effective solutions for healing from traumatic experiences. Be sure to click on the red "Attend" button below to come to the event. We look forward to seeing you there. This group is sponsored by the Dianetics & Scientology Life Improvement Center.

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.
