• What we'll do On https://blackecon101.podbean.com/ Thursdays at 6 pm. discussing the economy....

Today we are Steve's Lab. RSVP and you'll be sent the location. It's in Silver Spring. ***Join us for an evening in an electronics lab where we will attempt to run clean scans of gold samples, and then clean up that data with post processing.*** This is a high sensitivity experiment, and we do not plan on being successful so early. But we've had promising results lately - so we will be putting in the time. We are NOT meeting at our usual location, but rather at Steve's house/lab. If you RSVP, you will get a DM with the address but it's located in Silver Spring. We will attempt full, clean lab - clean tip repeated scanning tests to see what we can learn and improve. We will experiment with online attendees, but if all possible showing up in person is strongly encouraged. Online join link is: - [https://meet.jit.si/mocomakers](https://meet.jit.si/mocomakers) Our community is building (and documenting for other teams) how to build a scanning tunneling microscope using a mix of common and 3D printed parts. This will allow us to scan and visualize a single atom - an ambitious we are doing over the course of a few months. The MoCo Makers community is one of the most innovative and competent groups in Maryland, and we've done everything from [publishing cancer research](https://pubmed.ncbi.nlm.nih.gov/38136356/), to [launching products](https://www.kickstarter.com/projects/gotim/cozy-curvy-multi-contour-pillow), [winning grants](https://covidinfocommons.datascience.columbia.edu/awards/2014255), and inspiring thousands. Now our biggest challenge yet has appeared. We are building a Scanning Tunneling Microscope, that will allow us to scan and visualize single atoms. To get a better idea of what we are doing, see our reference project here: [https://www.youtube.com/watch?v=7N3OqTEq08g](https://www.youtube.com/watch?v=7N3OqTEq08g) All starting CAD, code, and reference files should exist. However, let's be the first Maker community to document the build process and share it with learners around the world. We will be publishing our work here -[ https://hackaday.io/project/202816-qt-panda](https://hackaday.io/project/202816-qt-panda) If you need a ride, let us know.

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.

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Facing Fascism,”** on the history, hallmarks, and lingering power of a deadly ideology, with Kevin Matthews, professor of history at George Mason University and teacher of courses on early 20th century European history. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-facing-fascism](https://events.ticketleap.com/tickets/profsandpints/nv-facing-fascism) .] Few political movements have aroused as much anger and fear as fascism. But despite its legacy of violence, persecution, and genocide, fascism continues to hold a strange attraction to many. Join historian Kevin Matthews for an in-depth look at an ideology that brought death to millions in Europe and yet continues to deeply influence our politics and culture. Dr. Matthews will start by discussing how the ideology of fascism arose in the aftermath of the First World War and took hold in Europe in the 1920s and 1930s. To give you a better grasp of what exactly fascism is, he’ll discuss its central themes: Anti-democracy. Extreme nationalism and anti-communism. The use, or threat, of violence in politics. Rejection of established values such as scientific objectivity. Denial of equal rights, especially for women. The assertion of power where a power vacuum exists. We’ll examine the rise and fall of two notorious fascist dictators, Adolf Hitler of Germany and Benito Mussolini of Italy. For a time it was believed that fascism died in the ashes of the Second World War, but it clearly didn’t, and we’ll look at where it remains a political force today. Finally, we’ll examine how fascism continues to permeate popular culture in ways that trivialize it, popping up in music from punk to Madonna, with its latent eroticism making it the subject of films such as *The Night Porter.* Having been called “the most self-consciously visual of all political forms,” it enlisted fashion leaders to produce uniforms and continues today to inspire a look known as “Nazi chic.” Dr. Matthews previously has given fantastic Profs and Pints talks on Ireland’s fight for independence and on World War II German submarine attacks off our coasts. He’s sure to leave you with a much better understanding of fascism and a recognition that is has hardly gone away. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.) Image: Benito Mussolini and Adolf Hitler during Mussolini's 1940 visit in Munich (photographer unknown / public domain).

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
