[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Doom and Dinosaurs,”** a look at how mass extinctions shaped the dinosaurs and what research on these events tells us about Earth life’s long-term prospects, with Ian Wilenzik, paleontologist and visiting assistant professor of biology at George Washington University. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-dino-doom](https://events.ticketleap.com/tickets/profsandpints/nv-dino-doom) .] Pity the poor dinosaurs. They lacked both scientific research to help deal with potential environmental catastrophes and places where they could have a beer and discuss it. You, on the other hand, have the opportunity to come to Profs and Pints to hear a fascinating talk on the impact of mass extinctions on dinosaur evolution and what research on dinosaurs tells us about biodiversity and Earth’s current biodiversity crisis. Dr. Ian Wilenzik, who has studied and taught courses on dinosaur evolution, population spread, and extinction, will leave you with a greater appreciation of the resilience of life on earth and how we’re both the product and source of biologically catastrophic events. Many of us are familiar with how a big meteor impact about 66 million years ago wiped out the Earth’s dinosaur population, leaving us only with their feathered descendants, birds. Less well known is how the Earth actually has undergone five periods of mass extinction that wiped out nearly all life, and how dinosaurs arose from one and endured another—both caused by volcanic activity—before meeting their match in the third. To ground his discussion, Dr. Wilenzik will talk about how we study mass extinctions by looking for geologic evidence of volcanic activity, meteoric blasts, and other catastrophic activity and of gaps in the fossil record after them. He’ll also discuss what makes a dinosaur a dinosaur, describing their distinct anatomical features. He’ll talk about how they and other forms of life evolved over long periods of time and were affected by extinction events. We’ll look at how the meteor-caused mass extinction that wiped out dinosaurs at the end of the Cretaceous paved the way for the rise of mammals and the emergence of primates, and, eventually, us. Looking ahead to future mass extinctions and what might survive them, we’ll talk about how that plant you forget to water might have the last laugh, as well as why crocodiles might be around a while. (Doors: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.)

**In a time of division and isolation, come be part of the community that's rebuilding the town square, one table at a time.** In BreadBreakers, we use the common space of the dining table to have conversations where neighbors can **hear, be heard, and know one another.** If you're hungry for good conversation and deeper community, join us for a Community Dinner in Reston and help blaze the trail to a healthier, more connected society and democracy. Here’s how it works: For just two hours, multiple tables of people set aside the need to "win" and instead focus on sharing, listening, and connecting. Guided by experienced table hosts, we'll tell our stories, try to understand each other, and practice being in community with those with different views or backgrounds. **At this dinner, participants will get to choose between three different topics, including some current events.** Topics range from the political, to the "slice of life", to the spiritual, to the philosophical, to the off-the-wall - but no matter which table you choose to sit at, you can be sure it'll be like no dinner conversation you've had before! You can also **suggest a topic** by emailing us at BreadBreakersInfo@gmail.com. Food will be provided for free. For those who wish to provide a donation to help fund BreadBreakers, you can [give here](https://pushpay.com/g/restorationrestonumc?fnd=pO6G-N7oO7FH7Mp1u-x6mA&fndv=Lock&r=No&lang=en&src=pcgl) or at the event. We'll have vegetarian and gluten-free options available. If you have any additional dietary restrictions (Celiac Disease, vegan, etc.) please let us know at BreadBreakersInfo@gmail.com so that we can implement the appropriate food handling procedures. **Join us, invite a friend, and be a part of the movement to mend our fractured society and normalize a better way of talking with one another.** BreadBreakers, an initiative by [Restoration United Methodist Church](https://restorationreston.org/breadbreakers) in Reston, VA, is a religiously inclusive community. All faiths and all stripes are welcomed. Our leadership, volunteer team, and community include people who attend Restoration and people who don't.

NOVA Code and Coffee is an inclusive, informal, co-working session. People of all skill levels are invited. The concept is simple, bring a laptop and ideas, we'll provide the coffee and donuts! Here's how it works: 1. At 10:15 everyone introduces themselves and briefly describes what brought them to Code & Coffee today (project, homework, networking, etc) 2. For the rest of the day, folks work in the communal space on their projects providing one another help and conversation as needed. Oh and they usually drink coffee and tea too! That's it! Hope to see you there! **Location** Our hosts are the Fairfax City Economic Development Building: [10300 Eaton Pl, Fairfax, VA 22030](https://www.bing.com/ck/a?!&&p=d7298231ca2df594df822003f9a93517c788fceefe1fcbb79c8976696e341bc6JmltdHM9MTc1MzIyODgwMA&ptn=3&ver=2&hsh=4&fclid=180d0745-3b7f-69a1-23a2-11433a7868e5&u=a1L21hcHM_Jm1lcGk9MTA5fn5Ub3BPZlBhZ2V-QWRkcmVzc19MaW5rJnR5PTE4JnE9RmFpcmZheCUyMENpdHklMjBFY29ub21pYyUyMERldmVsb3BtZW50JnNzPXlwaWQuWU44NzN4ODI4MTk2Mjg0NTk5MDM4MTU0MiZwcG9pcz0zOC44NjE0NDYzODA2MTUyMzRfLTc3LjMwMjE3NzQyOTE5OTIyX0ZhaXJmYXglMjBDaXR5JTIwRWNvbm9taWMlMjBEZXZlbG9wbWVudF9ZTjg3M3g4MjgxOTYyODQ1OTkwMzgxNTQyfiZjcD0zOC44NjE0NDZ-LTc3LjMwMjE3NyZ2PTImc1Y9MSZGT1JNPU1QU1JQTA&ntb=1) Conference Room A- Large, Floor 1 This is a new venue for us, so give us some time to get more details about it.

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“The Twister Talk,”** on tornadoes and advances in our understanding of them, with Jeffrey Halverson, professor of geography and environmental systems at the University of Maryland Baltimore County and author of *An Introduction to Severe Storms and Hazardous Weather.* [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-twister-talk](https://events.ticketleap.com/tickets/profsandpints/nv-twister-talk) .] Springtime brings tornado outbreaks and devastation across the United States. The good news for those of us who anxiously eye the skies: Tornado science is rapidly evolving and improving, as are the means by which we detect funnel clouds and warn of their approach. Get up to speed with what’s known about tornadoes with the help of Dr. Jeffery Halverson, a severe storm expert with the *Washington Post* Capital Weather Gang who previously has given excellent Profs and Pints talks on hurricanes and snowstorms. He’ll describe how, with the help of research conducted by tornado hunters, meteorologists are using ever more sophisticated computer simulations and datasets to try to “crack the code” when it comes to how and where tornadoes form. We’ll look at how science teams wielding Portable Doppler Radars on small trucks are learning that tornado wind speeds are much stronger than once presumed. We’ll consider how decades of data are changing how we think about “Tornado Alley,” and we’ll review what’s known about the relationship between tornadoes and climate change. Professor Halverson will conclude by discussing the technological strides being made in terms of tornado warning and detection, and how tornado scientists are teaming up with social scientists to gain a better understanding of what leaves us vulnerable to natural hazards. (Doors: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.)

The next NoVABeerSec event - "Informal Gathering of Security Minds Over Beer" will be Wednesday, April 29th, 5:30PM til 7:30ish at Aslin Beer Company - Herndon Taproom (767 Elden St., Herndon VA 20170). **Venue for April:** Aslin Beer Company (https://www.aslinbeer.com) - Aslin Beer Co. was founded in 2015 by Andrew Kelley and Kai Leszkowicz. The name, Aslin, comes from the family that connected Andrew and Kai through marriage; they each married a daughter from the Aslin Family. Andrew’s professional background was in finance and consulting, while Kai worked in public service. They bonded over a shared interest of craft beer and home-brewing, which eventually lead to the idea that “We can do this too.” **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. We do know there are folks that have changed roles since we last met so please also let us know if we need to add new contact info for people. Have a great week and see you later this month! Cheers, Rinaldi Rampen & Mike McCabe of @NoVABeerSec

Spec-driven development flips the traditional workflow on its head: instead of code being the source of truth, the specification becomes the backbone of design, collaboration, and delivery. In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects.

Join us for conversations that go beyond small talk, diving into topics like the shifting nature of spirituality, the challenges and joys of midlife transitions, the impact of culture and capitalism, and the search for meaning in art, travel, and daily life. Our gatherings are about genuine, thought-provoking dialogue, with no set leader or strict agenda—just an open space to share ideas, perspectives, and experiences that matter to us. The direction of the discussion is shaped by everyone who shows up, making each event unique and enriching. Come ready to share, reflect, and connect with others who are also seeking deeper conversations. Let the conversation flow from topic to topic. Optional questions are listed below.
