System on Chip

No sign\-ups required \| All levels welcome \| 21\+ If you're looking for a casual game of chess in a fun atmosphere, this event is for you! Members range from beginner to master level, and games are played both with and without time controls. There are dozens of players each week, with only a fraction of the participants registering on meetup. This event is held at a bar, the Board Room, in Washington, DC, and is intended for 21+ players. We meet upstairs, on the mezzanine. Upon arrival, fill out a name tag and indicate your relative skill, to facilitate match-ups. Chess sets and boards are provided. We don't have club clocks, but most people use the Chess Clock app from Chess.com to play timed games.

**Now is the Time for Action!** ​The US must lead the way on regulations to ban unsafe superhuman AI! ​Humanity stands at a crossroads. Unless we work together, reckless development of artificial intelligence (AI) could endanger us all. A handful of companies are racing to be first to build superintelligent AI – systems vastly more powerful than human beings. Meanwhile, leading AI scientists and whistleblowers warn that these systems could escape our control and cause the end of human civilization. ​But this is not inevitable. We can make the wise choice. Rival nations have worked together in the past to reduce nuclear arsenals, restrict chemical and biological weapons, reject human cloning, and save the ozone layer. We must do the same now for superintelligent AI. ​Join PauseAI at our US Capitol Day of Action. As our volunteers from across the country meet with their representatives, we will gather before the Capitol Building to demand regulations on unsafe, superintelligent AI. ​We will be gathering on the West Front Lawn of the US Capitol Building, on Monday, April 13th, 4-6 PM. This demonstration will be fully permitted by the US Capitol Police; it will be a peaceful, lawful, and respectful call for Congress to protect their constituents. ​For more information, check out [pauseai-us.org](https://pauseai-us.org/?utm_source=luma). ​Join us and make your voice heard. Help us ban unsafe AI!

[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).

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

In this local meeting, you will discover knowledge that you can use to get over the past. The key to improving your personal motivation, self-confidence, and happiness is to get over your painful memories. When you become free of your past, you will be free from stress, anger, anxiety and depression. Studies show that negative emotions can affect your health. By being free of negative emotions, believe it or not, you will most likely even look younger, feel more energetic, and become healthier!

This group is brought to you by the Dianetics and Scientology life improvement center.

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?
