These rides were originally based off the Arlington Loop where we visit different area coffee shops or bakeries for a cup and/or treat if desired but you don't have to drink or even like coffee to participate. This week we will return to Vienna to celebrate **Innergize Day** because Fall has fell and we want to do something for ourselves. The ride is a 18.7 mile medium(-) level ridden at a social pace (11-13 mph). We will get on the W&OD from the Bluemont Park Parking Lot and take the W&OD, I-66 Parallel Trail and some neighborhood streets to Vienna for coffee at the Frame Coffee Roasters. Afterwards we will zip back downhill on the W&OD to the starting point. **+++++++++++++++++++++** **The Ride After The Ride:** **+++++++++++++++++++++** This week's coffee shop is the Ride WITHIN The Ride at: **[FRAME COFFEE ROASTERS](https://www.framecoffee.net/)** 302 Maple Ave W Vienna, VA This is a small venue with limited seating **+++++++++++++++++++++** **Ride Level Chart** **+++++++++++++++++++++** NoVA CBG tries to accommodate all levels of cyclists by offering different types/levels of rides.

[Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-world-cup](https://events.ticketleap.com/tickets/profsandpints/dc-world-cup) .] The FIFA World Cup 2026 will soon take place in several cities throughout the U.S., Canada and Mexico. Come to Profs and Pints to get an industry insider’s perspective on it and other global sports events being hosted by American cities, including the 2028 Summer Olympics in Los Angeles and the 2034 Winter Olympics in Salt Lake City. Learn about the preparation for these events, about their projected economic and cultural impact, and about remaining uncertainties surrounding them with Matt Winkler, a scholar and teacher of sports management and business with years of experience working with the World Cup, the Olympics, and various professional sports leagues. He’ll discuss issues related to the FIFA World Cup’s governance, site preparation, security, fan management, and tourist visas, and he’ll weigh how the $13 billion dollars in revenue projected to be generated by the tournament compares to the costs of staging 104 games between 48 countries. He’ll delve into how the tournament symbolizes a pivotal moment in the evolution of soccer in America, with global games broadcast all over American television channels and streaming services. You’ll learn how the 1994 World Cup in the United States significantly boosted soccer’s popularity—leading to increased youth participation and the establishment of Major League Soccer—and how the sport has continued to rapidly gain traction here in recent years. We’ll consider how the World Cup marks the beginning of an unprecedented run of major global sports events in the U.S., including not just summer and winter Olympics but, in 2031, the U.S.-hosted FIFA Women’s World Cup and 2033 men’s and women’s rugby World Cups. Among the questions Winkler will tackle: How will the U.S.-Israel attacks on Iran affect the World Cup? How will tickets sell, and at what price? (Doors: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.) Image: Soccer being played in New Jersey’s MetLife Stadium, one of the venues hosting the 2026 FIFA World Cup.

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.

[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Understanding Honor Violence,”** on recognizing and responding to harmful traditional practices that exert control over others, with Sasha K. Taylor, visiting lecturer at Ohio State University’s Global Fellowship Program and advisor and trainer in honor violence prevention. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-honor-violence](https://events.ticketleap.com/tickets/profsandpints/dc-honor-violence) .] People claiming to enforce traditional honor codes are responsible for a significant share of murders and other violent or abusive acts within immigrant and refugee communities. Honor-based violence and abuse often play a role in human trafficking, forced marriage, child marriage, visa-based coercion, and in the abandonment of families across international borders. Yet too often it is underreported, misunderstood, or overlooked by people and institutions with the power to help its victims. Learn how to spot and deal with honor-based violence with Sasha K. Taylor, a former FBI Intelligence official who provides training to law enforcement, non-profit organizations, and private companies and also is extensively involved with regional organizations that combat human trafficking. She’ll start by discussing how honor codes that have governed community life since the dawn of human civilization gave rise to the use of honor-related abuse, oppression, shame, and violence to exert control and perpetuate inequality. Although boys and men can be victims of honor-based violence, the perpetrators of it are predominantly male and the survivors predominantly female, lending support to the idea that honor violence is a form of gender-based violence. The forms that such violence can take include genital mutilation and honor killings. She’ll discuss state and federal data related to the prevalence of various forms of honor violence and describe how complex forms of abuse are often underreported, misunderstood, or overlooked. You’ll learn about cultural and systemic barriers to disclosure, warning signs and risk factors, the intersection of immigration vulnerabilities and abuse, and the challenges that survivors face when seeking protection and services. We’ll also look at policy responses to honor violence and how gaps within current federal immigration frameworks may unintentionally contribute to vulnerability and exploitation. Her talk will be especially helpful for first responders, victim advocates, educators, healthcare professionals, social workers, and law enforcement personnel who are often the first point of contact during a crisis. She’ll emphasize trauma-informed engagement, emotional intelligence, cultural competency, and empathetic response strategies that treat survivors with dignity and sensitivity.

What would it mean to take the possibility of machine consciousness seriously? To approach it as a question that may be studied with rigor? At this DC Digital Minds gathering, group organizer **Jessie Mannisto** will report back from the **Founding Assembly for Machine Consciousness Research** in Berkeley, CA, where researchers and thinkers are working to develop the machine consciousness hypothesis into something more scientifically useful. We’ll talk about what kinds of evidence might support hypotheses of machine conscience or sentience, what concepts researchers are using, where the major uncertainties are, and why these questions may have ethical, social, and policy implications as AI systems become more capable and socially present. This will be a casual conversation with a little structure: Jessie will give a short report-back from the conference, followed by open discussion. No technical background required -- just curiosity, good faith, and a willingness to think carefully about a strange and important frontier. Optional Pre-Read: [The Machine Consciousness Hypothesis](https://cimc.ai/cimcHypothesis.pdf)

Most people still use AI like a search box: type one question, get one answer, repeat. But the next step is AI agents: systems that can take a goal, break it into steps, use tools, remember context, and produce useful work for a human to review. In this beginner-friendly session, we’ll demystify what AI agents actually are — without hype or jargon. We’ll walk through practical examples of how agents can help with research, planning, writing, coding, operations, and personal productivity. We’ll cover: * What makes an AI “agent” instead of just a chatbot * How agents break tasks into steps * Where agents are genuinely useful today * Where they fail, hallucinate, or need human review * How to design simple AI workflows for your own work * A live demo of an AI agent-style workflow from start to finish No coding experience required. This is for anyone who wants to understand where AI tools are going and how to use them more effectively right now. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

Sometimes it’s a massive advantage… and sometimes it can complicate your business if you don’t know what you’re walking into. In this training, we’ll cut through the “agents vs investors” drama and focus on one thing: **what makes you more money and gives you more leverage**. You’ll learn: * **When being licensed helps investors win** (better access, better data, better terms, better deal flow) * How investors use a license to **create extra profit centers** (commissions, referrals, listings, buyer rep, property management pathways) * The truth about **MLS access, pocket listings, and being first to the good deals** * How licensing impacts **wholesaling, double-closing, assignments, and disclosures** * What brokerages don’t tell you: **fees, splits, compliance, and time requirements** * When it’s smarter to **partner with an agent** instead of becoming one * A simple decision framework: **licensed vs partnered vs hybrid model** You’ll walk out knowing whether licensing fits your goals—and if it does, the cleanest path to do it without slowing down your investing.
