[Profs and Pints DC](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/dc-digital-detectives](https://events.ticketleap.com/tickets/profsandpints/dc-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).

**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!!!!

[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.)

This training is designed for real estate agents who want to learn how to play the Agent Investor game. The goal of this training is to help you flip your income into ownership. ━━━━━━━━━━━━━━━━━ **Inventory is the lifeblood of every market.** **And whoever controls inventory controls the opportunities, the buyers, and the leverage.** How to Generate a Steady Stream of Motivated Sellers teaches you a focused, repeatable system to consistently find and serve motivated sellers—without chasing random lead-gen tactics or relying on luck. Motivated sellers create multiple pathways: traditional listings, cash offers, creative solutions, rental opportunities, and investor deals. When you know how to help people in distress, you create impact and income at the same time. In this session, you’ll learn the core framework for building predictable motivated seller opportunities using ZONE: * Zero in on your target * Own the mindshare * Nurture the list * Expand your influence You’ll also learn the highest-probability seller funnels, including: * Pre-foreclosures (homeowners who need real help and clear options) * Absentee owners / tired landlords (10+ years ownership, deferred maintenance, vacancies, tax pressure) We’ll walk through the exact steps to build your first seller ZONE: get the list, segment it, create messaging, call the list, market weekly, build relationships—and control inventory. You’ll also get a proven seller message that converts because it offers real options: * 24-hour cash offer (speed + convenience) * traditional listing (maximum price) * renovate now, pay at settlement (maximize equity with zero upfront cost) This positions you as a problem solver, not a salesperson—and one strong seller ZONE can feed your business for years. ━━━━━━━━━━━━━━━━━ **Did you miss it?** [Watch all GRID Reston event playback on YouTube](https://www.youtube.com/playlist?list=PLOTh5kxLLJI1G3VH6Pqhlhu0uTA8yrdpi) ━━━━━━━━━━━━━━━━━ **Join the GRID Facebook Community** [Join the online GRID community here](https://www.facebook.com/groups/gridinvestor) to post deals, ask questions, and connect with other investors across the globe.
