Doubles Volleyball - Competitive BB-A level @Bluemont Park Let's get together to play some fun A level Doubles games at Bluemont. Format: Doubles COST: FREE Court Type: Outdoor grass Minimum Skill Requirements: A level (click [here](https://docs.google.com/document/u/2/d/1PojSi4qdlRsv1msCHhvpQ43iDc4FfzQwpWCc3kafVMY/mobilebasic) for details) Attention: 1. This event is not always on a first come, first served basis. Those who can bring a net and ball, may get priority over others on the waitlist. 1. Since skill levels are self-reported, some attendees may not meet the expected level in reality, so we encourage you to choose a partner you can enjoy the game with, and since this is a competitive event, it is okay if you make a strong team and win all the games. 1. Since people arrive at different times, each group of 1. Players will set up and claim a net as they arrive, and may continue playing without rotating until all nets are set. ——— Smiley Social documents: [Group Rules](https://docs.google.com/document/u/2/d/1HrG35p_0M08leRvCp8XWG3CMkr_GL928XFabl5T6Dvg/mobilebasic) [Liability Waiver](https://docs.google.com/document/u/2/d/1W2mq-7m99lmvd7gdWYaSUFtvVg4UGnzV6koafAbHmco/mobilebasic) [Volleyball Levels](https://docs.google.com/document/u/2/d/1PojSi4qdlRsv1msCHhvpQ43iDc4FfzQwpWCc3kafVMY/mobilebasic)

Volunteer with us refurbishing donated bicycles to help us get them back out in the community! This event is open to both new and existing volunteers. No mechanical experience is necessary. Note: The warehouse location is in the alley behind 1502 Mt Vernon Ave. Enter through the gray door next to a roll-down garage door. If you drive to the location, be sure to park in the street, not in the alleys or parking lots surrounding the warehouse. And wear clothes you don't mind getting dirty with bicycle grease! Please be aware that volunteers under 18 need a parent or guardian to accompany them to their first volunteer experience and sign a liability waiver, while volunteers under 16 need a parent or guardian to accompany them at all times while volunteering with Vélocity.

**Location**: Tysons-Pimmit Regional Library (Virginia) Conference Room A game development **Working Session** involves 3 key parts: 1. Tell people what you're going to do 2. Actually do stuff 3. Show people what you did That's what we'll be doing for this meeting. We'll briefly tell each other what we're going to do, then work on our projects, then at around 5:30 wrap up to show each other what we did and chat for a bit. You don't have to stay the whole time, so feel free to drop in and out as you have time. All game development skill levels welcome. Whether you're bringing a game you're trying to ship in a month, or you're just planning on following some tutorials or trying out a new tool to improve your skills, use this time to make progress. Working sessions also train you to think about the scope of your work: pick a chunk of work that you can complete in the time that we have. That way you can end the working session with a feeling of accomplishment! **What to bring**: Laptop, Charger, maybe a power strip if you have one handy, any other game development tools you need. Try to download any software you need before the working session. There is Wifi at this location, but it may be slow if you have to download any large files.

Date: June 7 2026 Sunday 10:00 am - Noon EDT Full title: Machine Learning for Reliable Quantum Computing: An Algorithm–Hardware Co-Design Perspective Summary: Reliable quantum computing requires co-design across the full stack, including algorithm structure, compilation, and execution, rather than isolated optimization of any single layer. This talk presents a unified framework in which these layers are jointly optimized under realistic hardware constraints. Structure-aware compilation exploits algorithmic interaction graphs to reduce circuit depth; joint optimization across mapping, term ordering, and algorithm parameters yields significantly improved success probability; and execution-layer analysis reveals that error mitigation effectiveness depends critically on circuit symmetry and native gate choice. While demonstrated on superconducting quantum processors, the underlying co-design principles are potentially transferable across architectures. Building on this foundation, the talk highlights machine learning as the key enabler for closing the feedback loop: data-efficient, parameterized noise models learned directly from workload execution data achieve substantially improved predictive fidelity over vendor models without the overhead of dedicated characterization. These insights situate the co-design perspective within the emerging framework of quantum deep learning. In this broader setting, the talk also presents an operational definition, a unifying taxonomy, and a benchmarking protocol grounded in explicit resource contracts. Speaker: Dr. Yanjun Ji has an interdisciplinary research background in Physics and Computer Science. In 2020, she completed my Master's degree in Theoretical Physics at Saarland University. In 2024, she earned her Ph.D. in Computer Science at the University of Stuttgart. She is currently a postdoctoral researcher at Forschungszentrum Jülich. She is committed to interdisciplinary research at the cutting-edge convergence of quantum computing and artificial intelligence. Her research encompasses both foundational theoretical investigations and the development of practical applications, aiming to serve society and benefit humanity. Moderators: Dr. Pawel Gora, CEO of Quantum AI Foundation [Quantum AI Foundation](https://www.qaif.org/ "https://www.qaif.org/") Dr. Sebastian Zajac, member of QPoland [QPoland - QWorld](https://qworld.net/qpoland/ "https://qworld.net/qpoland/")

## 🤝 Host Information A co-hosted event by ProductTank Columbus & Women in Product Columbus 💡 About the Workshop AI adoption is stalling across organizations — not because of a lack of motivation or tools, but because it's fundamentally a behavior design challenge. This hands-on workshop applies proven Behavior Design models and methods to help you move from a vague organizational wish to boost AI adoption to 3-5 concrete, testable interventions you can act on starting tomorrow. Whether you're a product manager, on a product team, or just someone trying to get AI to actually stick at work, you'll leave with a clear picture of what's worth focusing on, what to ignore, and how to drive real, sustained adoption — no guesswork required. 🛠️ What to Bring Laptop: Fully charged and ready to go. AI Assistant: Have your favorite AI assistant pulled up. (Dom will be using Claude, but feel free to use whichever assistant you prefer!) 🍕 Logistics & Perks Food & Drink: Pizza and drinks provided!

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD
