Let’s reboot the DC Postgres Meetup series! This inaugural meeting will be hosted by John Porvaznik and Eddie Pickle and all are welcome. We’re actively looking for speakers, co-hosts, event spaces and other folks that want to help bring this group back to life. If you can’t make it but want to be involved in the future, please let us know. John Porvaznik will present a talk on Postgres fundamentals including shared buffers, memory usage, pages, and more. John is a long time PostgreSQL Engineer and DBA in the government space with focus on ETL / Data Ingestion, PostGIS and spatial data sets, query optimizations, Database Design // DDL, benchmarking and specifications, data health, and system healths and monitoring. This meetup will be hosted near the Snowflake office in Tysons (event space sponsored by Snowflake). We’ll have pizza and drinks for folks. 6:00 arrival and networking, 6:30 talk followed by discussion, 7:45 close. The event is at 1750 Tysons Boulevard, McClean, VA, 22102, in the 1750 Tysons Conference Center. This is Metro Accessible from the Silver Line to Tyson's Corner station.

Learn to manage stress and achieve self-growth through simple relaxation and Meditation. Heartfulness Meditation is a simple, modern, methodical approach to meditation. Rather than homing in on your breath or repeating a mantra, you simply focus inward, on your heart, to cultivate inner strength and serenity. Heartfulness meditation is gaining traction in recent years. It focuses on the heart, allowing individuals to connect with themselves on a deeper level, and ultimately achieve peace, relaxation, and clarity. It is a practice that encourages patience, self-compassion, and acceptance, helping cultivate a deeper appreciation for the present moment. This practice is offered with love and at no cost

**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 is NOT an official **Bike Rockville with RBAC** ride but a joint effort with our local Trek shop. Join the **Trek Rockville store** for a spring group ride in Poolesville and explore the Montgomery County Agricultural Reserve. You must be able to ride an average of 10 mph for 20-30 miles on moderate terrain. We will make an effort to stick together and regroup, but there is no sweep. Ride leader average pace is around 11.5 mph.

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 :)

**Sellkirk paddles will be available for all who attend to try and hopefully learn the game. if you’re interested, you can buy one.** **This is INSTRUCTION PICKLEBALL for** **Beginners.** **Note $5 fee for wear and tear on paddles and replacement of pickle balls.** **Reminder this is for beginners maybe you’ve taken two or three of the classes before. The idea is to give others a chance to learn the game** **so you could be put on the waitlist.** 
**
We can begin by just hitting the ball around (Dinking and Serving) until you’re comfortable and then start the introduction to Pickle Ball.** **Please study the rules of Pickleball. There will be a quiz. ** **https://www.goodhousekeeping.com/health/fitness/a41889595/pickleball-rules/?utm_source=google&utm_medium=cpc&utm_campaign=mgu_ga_ghk_md_dsa_prog_org_us_a41889595&gad_source=1&gbraid=0AAAAADA2MEqo78AlxWw25v72aAqTYZy2o&gclid=CjwKCAiAtYy9BhBcEiwANWQQLzWcA4GRJ5dNAtBpRG0nMJqvUlr67XGuB8hSrEaEZmWioeNiorM6jRoC0BkQAvD_BwE** **If I am late take the court that has the blue pickle ball lines on it to the far entrance to the court.
There is a Porta Johns at this location** **Bring a baseball cap, sunglasses and water**

[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).
