[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“What Digital Detectives Find,”** on the afterlife of your digital data and the methods of those who investigate it, with Jim Jones, associate professor at George Mason University and cyber security and digital forensics expert. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-digital-detectives](https://events.ticketleap.com/tickets/profsandpints/nv-digital-detectives) .] What happens when you delete digital data such as a picture, video, or email message? The truth is that “deleted” doesn't mean “gone,” and digital forensic investigators can extract and make sense of the residual fragments left over from data often assumed to be gone forever. Learn about the field of digital forensics—and the lessons it offers those who worry about sensitive data being exposed—with Jim Jones, who has been a cyber security and digital forensics practitioner, researcher, and educator for more than 30 years. You’ll learn how all investigations today, criminal and otherwise, to some degree involve digital forensics, an interdisciplinary field that draws from computer engineering, computer science, information technology, law, and ethics. Digital forensics doesn’t just respond to specific incidents, but also seeks out threats within organizations, analyzes malware, and buttresses cyber security. Much of the work of Dr. Jones, his colleagues, and students involves examining digital systems of all types to understand how data persists and decays and how it can be found and recovered. Dr. Jones will discuss how what happens to the digital data that you deleted depends on the type of device you are using, along with a host of other factors. You'll learn how digital data is stored on different devices and what does and doesn’t happen when you delete that data. You'll see examples of data extracted from different devices, demonstrations of what can be inferred from these remnants, and how investigators can tell if such remnants are genuine or not. Finally, you'll learn about strategies to mitigate the risk of exposing sensitive data. Dr. Jones will sort those that work from those that don’t. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.) Image: A digital forensics examiner works with evidence in the FBI’s New Jersey Regional Computer Forensics Laboratory (FBI photo).

The problem of climate change is a significant one, but What If We Get It Right? reminds us that with passion and ingenuity, there is so much we can accomplish.”—Roxane Gay “This book had me at its title. Through a collection of thoughtful essays and interviews, Johnson explores the possibility of getting it right with a visionary group of environmental leaders, activists and other big thinkers working on the front lines. Johnson, who has become a prominent voice on climate solutions, reminds us that there is also joy in working toward a future where we can all thrive.”—Los Angeles Times “This is the book we’ve been waiting for—a brilliant mix of creativity and wisdom that feels like we’re eavesdropping on intimate conversations with the world’s most brilliant change-makers. In What If We Get It Right?, Johnson weaves together art, poetry, and expert interviews into a deeply human exploration of the interconnected challenges we face. The result is a vision of a future filled with joy and possibility, where fixing one problem helps us solve many more.”—Katharine Hayhoe, climate scientist, author, and UN Champion of the Earth “An optimistic bent and eager embrace of solutions… these conversations are as much about ‘getting it right’ as they are about what we are currently getting wrong. Johnson is a top-notch interviewer, and her guests are insightful and candid.”—Scientific American “An entirely credible (and entirely enchanting) voice… Ayana Johnson is no Pollyanna. She’s a hard-nosed and extremely competent scientist who has not shied for a minute from facing the hard truths.”—Bill McKibben “Rigorous, elucidating, and hopeful in the most catalytic sense, this volume will stiffen your political will and open your mind and heart. It could arrive at no better moment.”—Rebecca Traister, bestselling author and writer for New York magazine “I believe that this is a book that the young among us have been waiting for. It is certainly the reset that we as societies and as elders owe to coming generations of humanity—and to our magnificent natural world.”—Krista Tippett, Peabody Award-winning broadcaster, a National Humanities Medalist, and a New York Times bestselling author “The climate crisis is terrifying, but also exhilarating—exhilarating because spectacular new ideas, approaches, and values are arising to address the terrifying stuff… Ayana Elizabeth Johnson's fantastic new anthology lets you listen to dozens of them.”—Rebecca Solnit, author, feminist, environmentalist “Critically, What If We Get It Right? reminds us of the most important solution of all: protecting and restoring nature, the magic of photosynthesis and water cycle. If you need a kick in the pants to roll up your sleeves on climate solutions, this book is for you.”—Yvon Chouinard, founder of Patagonia “If you are enamored with possibility, as I am, let the perspectives gathered in these pages fill you up and propel you on. Ayana Elizabeth Johnson has prepared a genuine feast for us. Savor every ‘what if’ for our shared future.”—Dr. Katharine K. Wilkinson, co-editor of All We Can Save and lead writer of Drawdown ### About the Author Dr. Ayana Elizabeth Johnson is a marine biologist, policy expert, writer, and Brooklyn native. She co-­founded and leads Urban Ocean Lab, a think tank for the future of coastal cities, and is the Roux Distinguished Scholar at Bowdoin College. Dr. Johnson co-edited the bestselling climate anthology All We Can Save, co-created and co-hosted the Spotify/Gimlet podcast How to Save a Planet, and co-authored the Blue New Deal, a roadmap for including the ocean in climate policy.

**Bluebells at Riverbend Park, Great Falls and Difficult Run a Mod. 10.5 Mile Hike** This is a two-park hike spanning 10.5 miles, beginning at Riverbend Park and winding through the uplands toward Great Falls. The trail follows the gorge and continues onto the floodplain, offering a variety of landscapes, stunning vistas, and about 800 feet of elevation change along the way. The hike winds its way back to Riverbend and its spring display of bluebells. Just 15 miles from downtown Washington, the Great Falls area stands out as premier natural escape from the city. Riverbend Park features over 400 acres of forest, meadows, and ponds. In the spring, these meadows and riverbanks come alive with blooming Virginia bluebells, creating a vibrant carpet of soft blue and pink hues. Bluebells are especially abundant along the Potomac’s floodplain, drawing hikers and nature lovers to this annual spectacle. Here, Potomac River abruptly plunges nearly 80 feet through a series of rapids, carving a narrow, mile-long gorge with sheer walls. Protected by National Park Service lands on both riverbanks, the hike rewards you with breathtaking views of nature's power—accented by a wonderful display of bluebells lining the water’s edge. NOTE: It is important to arrive by 8:45 or earlier as the parking lot fills quickly at this time of year. **Time to Meet**: Please meet at 8:45 for introductions and sign in.

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

**Agenda :** * 4.45 to 5.00 PM ET: Food and Networking * 5.00 to 5.50 PM ET: "Hands-On : GitHub Copilot SpecKit" Hello Everyone! Please join us for our April 14th edition of the AI-ML MeetUp. **Please note this is an in-person meeting and light refreshments/food will be provided. You will need a government-issued ID to enter the facility.** **Title:** Hands-On : GitHub Copilot SpecKit **Description:** Spec-Driven Development **flips the script** on traditional software development. For decades, code has been king — specifications were just scaffolding we built and discarded once the "real work" of coding began. Spec-Driven Development changes this: **specifications become executable**, directly generating working implementations rather than just guiding them. In this hands-on lab, we will be covering building your application using SpecKit. Pre-requisites: VSCode v1.107, GitHub Copilot, Python 3.13 + uv, Git installed. **Location:** The meeting will be hosted in the Applied Information Sciences ( AIS ) office in Reston, at 11440 Commerce Park Dr # 600 · Reston, VA. The location is also right off the Silver Line metro's Wiehle-Reston Metro Station. **Parking:** Parking is paid and can be validated at the AIS office reception. We will meet in Room Lake Anne. We hope to see you all there!!!!

Join us for another session of our study group as we continue our coverage of the book Domain-Specific Small Language Models. In this session, we will attempt to cover Chapters 9 on "Advanced Quantization Techniques" and Chapter 10, on "Profiling Insights" to understand resource utilization by an SLM. This isn't just a lecture! Come ready to ask questions, share insights, and code along. Whether you're a beginner or have some experience, this is the perfect opportunity to continue to learn together. If you plan to work with the code on your own laptop during the session, try and download the code from here https://github.com/virtualramblas/Domain-Specific-Small-Language-Models ahead of time.

We will be meeting at Starbucks to learn together. Come with an online class you're already going through or an interest and we will try to connect you with a course where you can learn it. Already have a skill you want to contribute to a Kaggle Datascience competition? We will work on these too! Laptop required :)
