**This talk has completely sold out in advance and no door tickets will be available.** [Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Mermaid Tales,”** a discussion of the enigmatic water spirits of East Slavic countries, with folklorist Philippa Rappoport of George Washington University. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/profs-pints-dc-mermaid-tales](https://events.ticketleap.com/tickets/profsandpints/profs-pints-dc-mermaid-tales) .] Be careful out there. According to Slavic folklore, in the late spring the rusalki, an East Slavic version of mermaids, emerge from lakes and streams to water crops and to claim lives. They're mostly beautiful, with wild hair and blazing eyes, and they’re more than happy to drag smitten young men to watery graves. Join Philippa Rappoport, an expert on Slavic folklore and rituals, for a discussion of the water spirits of Ukraine, Belarus and Russia and the traditions centered around them. She'll describe how rusalki were both revered and feared by people who would sing songs in their honor while carrying protective charms. You'll learn how East Slavic mermaid lore permeated wedding rituals and parades, inspired the construction of effigies, and reflected beliefs about women that, throughout the world, have translated into a lot of concern over how women wear their hair and cover their heads. Philippa has wowed crowds with fascinating talks on East Slavic nature spirits and folktales related to the underworld and winter. Her accounts of mermaids promise to be equally entertaining. (Doors: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.) Image: Rusalki as painted by Andrey Shishkin in 2015 (Creative Commons).

The next NoVABeerSec event - "Informal Gathering of Security Minds Over Beer'' will be Tuesday, June 23rd, 5:30PM til 7ish at Starr Hill Tysons Biergarten (1805 Capital One Dr S Suite 1100, Tysons, VA 22102). **Venue for June:** Starr Hill Brewery / Biergarten (Outdoor) **\*\*\* The Biergarten is primarily an outdoor venue, if the weather isn't cooperating we'll shift into Brewpub located on the ground level next to Capital One Hall \*\*\*** In the early 1990s, Charlottesville native, Mark Thompson took his biology degree from James Madison University and moved to Portland, Oregon, ground zero for craft beer’s growth in America. The natural blend of art and science poured into the brewing scene inspired him to take up the craft. Working alongside brewers in Oregon and Colorado, Mark honed his own artisan beer recipes. An old friend looking to start a brewpub and music hall back in Charlottesville eventually lured Mark back to Virginia. In September 1999, they partnered to found Starr Hill Brewery out of a passion for great beer and live music. Named after the local neighborhood, the brewery shared its original space with the Starr Hill Music Hall. The historic storefront on Main Street was once home to the state of Virginia’s first craft brewing operation, Blue Ridge Brewing Company. **Additional Info:** We are an inclusive group, so if we missed anyone please let us know or if you want to bring your significant other/spouse please do. Have a great week and see you next month! Cheers, Rinaldi Rampen & Mike McCabe of @NoVABeerSec

Title: Quantum Computing for Business (Exploring Opportunities Available Today) Date: June 27 2026 Saturday Noon - 14:00 EDT Summary: Big media reports that current quantum computers are not able to attack business problems at scale. In Ron's experience, this is only about 95% true. He has found that certain types of quantum computers, specifically quantum annealers, are very good at solving constraint based optimization problems at business scale. This presentation will answer the question “What is quantum computing?” by comparing quantum computers to classical computers and describing the various types of quantum qubits. Ron 'll introduce what quantum computers can be used for and what they shouldn't be used for. Next, Ron will look at a number of quantum computing use cases that are currently available to businesses today. Finally, Ron ’ll present conclusions with a brief discussion of future hardware. There will be time for Q & A. Speaker: Ron has been fortunate to have worked in a broad range of technical disciplines during his career. Areas in which he developed expertise and innovative results include, digital hardware design, silicon functional architecture (chips), computer language compiler development, and medical software. Ron has recently immersed himself in quantum computing technologies and has obtained more than a dozen certificates across the quantum spectrum. These technologies include various hardware platforms, numerous quantum programming frameworks and quantum sensors. As a co-founder and CQTO of B2Quantum, Inc, Ron has served as a quantum computing Subject Matter Expert (SME) for a large pharma company. As a SME, he performed quantum computing use case analysis, strategic planning, budget guidance and risk analysis. Outside of the technical arena, Ron is a licensed pilot, certified open water SCUBA diver, bicyclist, wood worker and a once in a while artist.

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

Whether you've never done improv before, or you've done it for so long you were quoted in *Truth in Comedy*, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup**! The idea behind improvised comedy is to create entire scenes from scratch. A suggestion is taken from the audience and laughter is built on the spot. This can be done in game form, like *Whose Line Is It Anyway, Make Some Noise,* or *Wild 'n Out*; it can also be done in a longer way, to tell a complicated story, like *TJ & Dave*. Our meetup, which is central Ohio's longest running (and FREE!) weekly comedy event, brings the games for you to play in a safe, supportive, and compassionate environment. Afterward, many members will hang out in *Gresso's* itself and get to know each other. Not only is this a lot of fun, but you get to work on thinking faster on your feet, your public speaking, plus it's an excellent way to meet new people and build relationships that will last a lifetime, and you do that while laughing your butt off! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "*Yes, And*" that you'll have a blast!

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.
