HPC Programming

**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.

It's June, and we have one class left in the Firefly Foundations class series meant to provide students the opportunity to learn about the House and about our way of being Pagan. If you've been with us from the beginning, well done! For the seventh and final class of the series, we'll be talking about the elements. We've mentioned them a few other times, especially when talking about quarter calls and during our class on magic, but this time we're going to dive into them with a bit more detail and discus a bit about the history of how the classical Greek elements ended up in our strange mashup of British folkways and ceremonial magic. When you RSVP for this class, you'll be asked to provide an email address. We'll send you a link to the class video at that address as soon as possible after we receive it. We keep won't share your email with anyone ever. Watch the video before the class date and time, and come to class with any questions you might have. During the class session, we'll be going over anything from the video you wanted to review, anything from the class series as a whole that you might want to go over again, and we'll do a bit of a show-and-tell about the various tools and toys that you might see crop up from time to time during House events, especially since so many of them are connected to the elements in some way or another. If you're comfortable with it, join us at the MLK Memorial Library. The exact room is TBD, but we'll update it once the room is reserved. Masks will be welcomed, but not provided, for in-person attendees. We will also have the necessary technology to allow folks to join in online via Google Meet if you prefer to attend remotely. Video conferencing information will be sent out the morning of the event. If you're connecting that way, please give us a few minutes past 3:30pm to get the stream online. This class is a part of our [foundations class series](https://docs.google.com/document/d/18-tA9ewEm1YEvY26jlWq07F2DT_-_HKwd-_wnl0l84g/edit?usp=sharing), which is only required if you wish to join the Firefly House as an initiate. If that does not interest you, then feel free to skip classes that you find less important for your journey. If you want to keep your options open with respect to initiation but cannot attend this session at the listed date and time, please contact the event host prior to the session. Keep in mind, you can only miss two of seven sessions in this way. Time spent with initiates of the House and your fellow classmates is an important part of knowing if you want to initiate. If you don't initiate, regardless of the reason, you're still welcome to all of the public events we organize. If you would like to, feel free to [join our Discord](https://discord.gg/RrS9XNzf9X) to chat with others in the Firefly House between sessions. This is also a great place to ask for help if you've lost a link to a video, for example. \*\*\* The Firefly House seeks to provide a friendly, safe environment in which all participants can engage in productive dialogue, sharing, and learning with each other in an atmosphere of mutual respect. We are committed to providing a harassment-free environment for all, regardless of gender identity or expression, age, sexual orientation, disability, physical appearance, body type, race, ethnicity, religion (or lack thereof), or technology choices. If you have any questions regarding this event, please contact the host.

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/")

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Psychedelic-Assisted Therapy,”** on findings, debates and trends in the use of psychedelic substances to treat trauma and other conditions, with Whitney Marris, instructor at the University of Buffalo’s School of Social Work, certified psychedelic-assisted therapy facilitator, and consultant to clinical trials. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-psychedelic-assisted-therapy](https://events.ticketleap.com/tickets/profsandpints/nv-psychedelic-assisted-therapy) .] Psychedelics are rapidly moving from the margins into the mainstream, and questions abound as the sociocultural and legal landscapes surrounding them shift. President Trump’s recent executive order expanding access to psychedelic drugs for certain conditions and accelerating research on them has both heightened interest and added to confusion. Learn more about the so-called “Psychedelic Renaissance,” and get help separating the hope from the hype surrounding it, with Whitney Marris, a leading trainer and facilitator of psychedelic therapy who has used it to treat trauma survivors, military veterans, and people with cancer. She’ll present foundational information on what we know about how psychedelics work. You’ll learn how psychedelic-assisted therapy differs from “trip sitting” and about what we know about the effects of “microdosing” versus “macrodosing.” We’ll examine what has been demonstrated to be helpful versus harmful before, during, and after a dosing session intended to support significant, sustainable change. Marris also will discuss the historical and cultural context of the use of psychedelic medicines for healing, and she’ll describe the ethical challenges that arise as such practices move from counterculture to clinic. We’ll look at emerging and evolving findings in the field, as well as at the roles being played by various financial interests and ideologies in determining the direction of psychedelic-assisted therapy and research on its outcomes. Attendees will gain an awareness of the need for new professional standards and regulatory guardrails related to such work, and they’ll leave knowing key questions to ask potential providers of psychedelic-assisted therapy. (Doors: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.) Image by Canva.

*Note: this is a demonstration event only, you **will not** shoot you own images. However, if you bring your camera we can test it for compatibility with the studio lights.* Bondage elements can add an extra layer of emotion and artistry to your images. Sample images on the internet are however dominated by BDSM style shots that are often sexualized and emphasize the model being in distress. In this demonstration Rachel and I show ways to use bondage elements in an artistic way. We explore the types of accessories that work best in artistic images and the best way to photograph them. Our model is Rachel Adams, an internationally known fetish model with many years of experience in this genre.
