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

**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.

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Dune and Messiahs,”** on word of saviors in religion and science fiction, with Peter Herman, former lecturer in theology and religious studies at Marymount University and scholar of religious and social themes in sci fi. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/northern-virginia-dune-messiahs](https://events.ticketleap.com/tickets/profsandpints/northern-virginia-dune-messiahs) .] *Dune: Part Three* is scheduled for release in December, and trailers for the epic space opera film have fans of the *Dune* franchise longing for it like visitors to its desert planet Arrakis long for water. Based on the second volume of renowned science fiction novelist Frank Herbert's *Dune* saga, the movie depicts the internal and external conflicts of protagonist Paul Atreides, an emperor treated by others as a messiah while being depicted as an antihero. The film will raise intriguing questions related to the presence of redeeming figures, or messiahs, throughout both science fiction and religious texts. Among them: What exactly do we mean by the term “messiah”? Why have many religious traditions looked for a redeemer to emerge? What happens if the messiah gets it all wrong? Explore such questions—and prepare yourself to enjoy the upcoming *Dune* film at a much deeper level—with Dr. Peter Herman, who has given several excellent, thought-provoking Profs and Pints talks on the *Dune* franchise. To center *Dune* in the discussion, we’ll look at the character of Paul Atriedes as a ruler who has launched a jihad across known space to reconquer it. His prescient visions show him that although the spread of religious war is not optimal, neither is it the worst potential future for humanity, and he allows excess and violence to continue in his name out of a conviction that it’s for the greater good. Throughout the book on which the upcoming film is based, Atriedes struggles with his followers' desire to view him as a divine figure. Dr. Herman, a trained theologian, will set such themes in the broader context of religious studies by discussing messianic figures across various religious traditions. Among them, Christianity names Jesus of Nazareth as the messiah, but he is hardly the first person in the canonical Bible given that title. Mainstream Judaism does not anticipate any similar, deified figure descending from heaven, but messianic strains of Judaism have looked for the arrival of a political liberator. Islam, from which Frank Herbert borrowed terms applied to Paul Atriedes, contains reference to someone serving not as a redeemer but as a heavenly guide. All branches of Buddhism situate within each new age of their cyclical cosmology a Buddha-yet-to-come. We’ll look at the human tendency in confusing times to seek out direct, uncomplicated answers and to embrace messianism as part of apocalypticism, which foretells a straightforward sorting process in which believers, as good people, see reward while their enemies, as bad people, see punishment. *Dune* fans will feel rewarded for coming to this talk.

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.

Styled after a 'pitch competition', this event is for entrepreneurs, and the entrepreneurial-curious. Learn about on-going initiatives from local area founders, and there will be ample time for networking. This event will bring together start-up founders and enthusiasts in the DMV area for an exciting opportunity to hear about a fellow founder, and give feedback on their pitch and product, and get to network around founders from the area. ## Details **Location:** 4200 Campbell Avenue Arlington, Virginia 22206 **Our Agenda:** 1\. Basic group introductions 2\. First "Pitch" Presentation \(\~10 minutes\) 3\. Community Q&A 4\. Second "Pitch" Presentation \(\~10 minutes\) 5\. Community Q&A 6\. Third "Pitch" Presentaton \(\~10 minutes\) 7\. Community Q&A 8\. Break out sessions & general networking **Speakers** Chelsea Acheampong (Nova Hospitality): Nova Hospitality is a consumer travel platform connecting conscious travelers directly with verified eco-lodges and community-run properties, redirecting tourism revenue back into local communities through transparent impact verification and direct booking Cameron Peltz (Caldarium): Caldarium is a health admin tech company building software solutions for medical practices, to automate prior authorization paperwork and detect errors in reimbursement claims, to ensure compliance and reduce their rate of rejection by Medicare and insurance payers, getting patients the medicine and surgeries they need more quickly and reliably, and doctor's offices paid for their properly documented procedures correctly the first time and therefore in consistent better financial health. Achinth Murali (Open Judgement Engineering): The Open Judgment Engine (OJE) is an open-source methodology and AI-assisted platform that captures the reasoning behind non-routine engineering decisions — when a judgment applies, when it doesn’t, what the expert does, why it works, and what failure it guards against — as structured, attributed artifacts called Judgment Primitives, embedded directly into the workflow gates where engineers already make those decisions. The goal is to make expert engineering judgment portable, searchable, and permanent — so that when a senior engineer retires, the reasoning behind their decisions doesn’t retire with them.​​​​​​​​​​​​​​​​ Join us for our monthly Pitch Labs meetup!

• What we'll do On https://blackecon101.podbean.com/ Thursdays at 6 pm. discussing the economy....

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.

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
