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.

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.

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.

[Profs and Pints DC](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/dc-psychedelic-assisted-therapy](https://events.ticketleap.com/tickets/profsandpints/dc-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.

A small team of AWS Solutions Architects not traditional software engineers, built AIRE Traffic Control (ATC), a production agentic AI platform now serving thousands of builders. We used AI at every stage: spec-driven development, AI-generated code, automated testing, and agentic workflows. In this talk, we'll share the real story, the architecture, the failures, the breakthroughs, and what we learned about driving adoption from 32% to 92% in 10 weeks. You'll walk away with practical patterns for building multi-agent systems, using AI-DLC methodology, and empowering non-traditional dev teams to ship production-grade applications.

RVSP on Luma!: https://luma.com/thq3hut1 ​Join us for an evening of data science side projects and networking! Come hear lightning talks about what people are building, meet other people working on cool stuff, and hang out. ​ Whether you're deep into a side project, just getting started on one, or curious about what other people are working on, this is a good place to be. Side projects are how a lot of us learn new tools, explore ideas, and connect with people—and they're a lot more fun when you have other people to talk to about them. ​The speakers tonight are folks who have been participating in our side project mentorship program since March. They submitted side projects they wanted to work on, got matched with mentors, and spent 12 weeks working on them. They'll be talking to you about some aspect of what they did or learned. **Schedule** * ​6:00 - 6:30PM: Mingling & food & drinks * Lightning Talks! * **Bryan Johns** — "Floodlines: The Geography of Institutional Memory" **Karen Zhu** — "Historic Recipe Explorer: Bringing Historic Cookbooks to Life with AI" **Aaron Schumacher** — "Pave the Planet: A new data visualization technique" * We'll add more as they come in. ​Speakers! TBA, but I'll add them as they come in!
