Information Retrieval

[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).

*From the [publisher's website](https://press.princeton.edu/books/hardcover/9780691268927/irans-grand-strategy):* Iran presents one of the most significant foreign policy challenges for America and the West, yet very little is known about what the country’s goals really are. Vali Nasr examines Iran’s political history in new ways to explain its actions and ambitions on the world stage, showing how, behind the veneer of theocracy and Islamic ideology, today’s Iran is pursuing a grand strategy aimed at securing the country internally and asserting its place in the region and the world. Drawing on memoirs, oral histories, and original in-depth interviews with Iranian decision makers, Nasr brings to light facts and events in Iran’s political history that have been overlooked until now. He traces the roots of Iran’s strategic outlook to its experiences over the past four decades of war with Iraq in the 1980s and the subsequent American containment of Iran, invasion of Iraq in 2003, and posture toward Iran thereafter. Nasr reveals how these experiences have shaped a geopolitical outlook driven by pervasive fear of America and its plans for the Middle East. Challenging the notion that Iran’s foreign policy simply reflects its revolutionary values or theocratic government, *Iran’s Grand Strategy* provides invaluable new insights into what Iran wants and why, explaining the country’s resistance to the United States, its nuclear ambitions, and its pursuit of influence and proxies across the Middle East. ***How to find us:*** We meet in the upstairs seating area at Zorba's in Dupont Circle.

***“I am struck with how rare it is to find a few good friends on the path. It is easy to find people who simply want to sit and be entertained by teachers, or who want to sit and entertain by playing the role of teacher. In other words, the quest for affirmation often outweighs the quest for truth.*** ***Yet you may have one or two good friends, and definitely have one or two waiting to be discovered. Find them; be thankful.”*** ***— Shawn Nevins*** 'What will make me happy in life?' ... 'Am I my thoughts?' ... 'What is Enlightenment?' ... We meet every week to ask questions like these in the pursuit of Self-Knowledge and Truth. We are interested in topics like: Zen, stoicism, spirituality, psychology, mindfulness, Nisargadatta, non-violent communication, Socrates, existential philosophy, Alan Watts, taoism, Eckhart Tolle, meditation, Ramana Maharshi, etc. But we are not affiliated with any dogma, philosophy, or religion. Our goal each meeting is to serve as mirrors for one another using question-based inquiry in a safe environment. In a session, every participant takes turns discussing the week's question or topic, and the group asks reflective questions without any agenda besides trying to understand the person's beliefs. A few other guiding principles of our group: * No one is obligated to share * Be honest with yourself and others * Do not try to convince others to believe or think as you do * Keep the focus on the person being questioned We meet at the [Bethesda Library](https://maps.app.goo.gl/GWMozF8zpY1m1PY26) every Monday. The library is a 5 minute walk from the Bethesda Metro on the Red Line, approx 25 minute Metro ride from Metro Center and Gallery Place stations. The library has a a parking lot with metered parking for $1/hour. \*\*\* WE WILL BE IN MEETING ROOM 3 UNLESS OTHERWISE NOTED ----- THE MEETING ROOM IS IN THE BACK OF THE LIBRARY \*\*\* Please contact us with any questions!

📚 Do you love reading, but wish you had a structure and a community to share your insights with? Join our small circle of curious minds (just 4 members per gathering) as we come together for an hour of focused reading—in the calm setting of a library or the cozy atmosphere of a café. Here’s how it works: First part: Quiet reading on your own—bring a book you’re exploring, whether it’s philosophy, history, psychology, literature, or anything meaningful to you. Second part: We regroup and each person shares key takeaways, insights, or questions sparked by their reading. This sparks a structured yet free-flowing conversation around ideas, perspectives, and personal reflections. Why join? Add structure to your reading habit. Discover new books, authors, and ideas through others’ choices. Build real connections by sharing and listening deeply. Socialize around something meaningful instead of small talk.

We’re excited to continue building AI in Practice with our monthly social! 🎉 Each month, we’ll host an informal happy hour and dinner at Upside on Moore in Rosslyn. Come join fellow AI builders, professionals, and curious minds for a relaxed evening of conversation, connection, and community. Whether you’re working on AI systems, advising on responsible adoption, or just interested in how AI is shaping law, compliance, finance, healthcare, defense, software, mission-driven organizations, or public service — this is a chance to meet like-minded people and help shape what this community becomes. 🍸 Drinks and food are available for purchase at the venue. 🤝 No formal agenda — just introductions, networking, and sharing what excites us about AI in practice. We’re so grateful for the early enthusiasm, and we look forward to seeing you each month as this community grows! **Date, Time & Location** 5:30 PM – 7:30 PM Tuesday 14 April 2026 Upside on Moore 1831 Moore Street Arlington, VA 22209

**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!!!!

​This meetup is for anyone building with OpenClaw (& Claude Code) or experimenting with other AI tools to create agents that can act and make decisions on their own. If you haven’t tried these yet, come hang out, ask questions, and see what others are building. We’ll trade notes, troubleshoot setups, and explore what it takes to run these systems openly on the web instead of inside closed platforms. Bring your laptop, grab some power, and jump into a night that feels part LAN party, part live build session, where people test ideas and show what their agents can actually do. 👉 [RSVP on LUMA](https://luma.com/53dx7no1) We’ll also have some fun by running a live test to see if a few of our agents can send Bitcoin back and forth and talk about why that’s a meaningful step for autonomous AI. It’s a chance to connect the dots between open AI tools, Bitcoin, and the wider goal of creating technology that no one can turn off. 👉 [RSVP on LUMA](https://luma.com/53dx7no1)

**​​​​​​​​A free, public workshop—no technical background needed** ​​​​​​​​ In just the past 8 months, AI has advanced at a pace that stunned even leading experts. These systems aren’t science fiction anymore—they’re reshaping work, relationships, and even crime in real time. ​​​​​​​​This workshop explores where AI may be in the next 1–5 years and what that means for your daily life. Together, we’ll tackle urgent questions like: * ​​​​​​​​**Jobs**: Could AI lead to mass unemployment—or entirely new kinds of work? * ​​​​​​​​**Crime**: How might AI supercharge scams, hacking, and even physical crime? * ​​​​​​​​**Companions**: Will people form deep emotional bonds—or even romantic relationships—with AI assistants? * ​​​​​​​​**Society**: How do top researchers think these trends will shape our future? **​​​​​​​​What you’ll get:** * ​​​​​​​​A fast-paced, beginner-friendly overview of today’s most powerful AI systems * ​​​​​​​​Live demos that reveal both the breakthroughs and the risks * ​​​​​​​​An interactive forecasting exercise where you’ll test your own predictions about AI’s impact ​​​​​​​​Come ready to explore a future arriving faster than most people realize—one that could transform not just how we work, but how we trust, connect, and even love.

Title: Potential Applications of Negative Radiation Pressure in Astronomy, Medicine and 2WQC Date: April 19 2026 10:00 am - Noon EDT (16:00 - 18:00 CET) Abstract: While we are used to heating and pushing with light, there is also optical cooling and pulling. I will talk about negative radiation pressure, potential ways to generate it, and its novel applications, like non-ionizing medical scanners, 2WQC (two-way quantum computers) in theory solving NP problems, also potential astronomical sources and their observation. Speaker: Dr Jarek Duda is an assistant professor at Jagiellonian University. He holds degrees in computer science (PhD), mathematics (MSc) and physics (PhD). He is mainly focused on physics foundations, information theory, statistical analysis, and is known for introduction of asymmetric numeral systems.

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.

We're bringing the community together for a casual happy hour with ServiceNow-themed trivia, food and drinks, and great conversation.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
