***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.

​A beginner-friendly workshop on superintelligence AI and how this new technology is evolving and impacting society. ​​**Free and open to the public — no technical background required** ​​What would it actually mean for machines to become smarter than humans—not just at chess or writing, but at *everything*? For decades, scientists and researchers have debated the idea of **Superintelligent AI**: systems that could outperform humans across nearly all cognitive tasks. What once sounded like distant science fiction is now increasingly discussed as a real possibility within our lifetimes. ​​This workshop is a guided, interactive introduction to the idea of superintelligence and the problem of **loss of control**—what happens if we create systems that are more capable than we are, but whose goals don’t perfectly align with human values. ​​**Over the course of the workshop, we’ll explore:** * ​​**Superintelligence:** What it means for an AI system to surpass human intelligence across domains, and how this differs from today’s AI. * ​​**Power and control:** Why advanced AI could wield enormous economic, political, and strategic influence—and why “just turning it off” may not be realistic. * ​​**Misalignment risks:** How systems pursuing the *wrong* objectives could cause harm even without malicious intent. * ​​**Societal choices:** How decisions made today—by researchers, companies, and governments—may shape whether AI becomes a tool we control or a force we struggle to contain. ​​**What you’ll get:** * ​​A clear, non-technical introduction to core ideas from AI safety and existential risk research. * ​​Live demonstrations of current AI capabilities, to ground abstract concerns in real systems. * ​​Small-group discussions and thought experiments that connect AI risks to everyday life, institutions, and incentives. * ​​A better mental model for evaluating headlines, hype, and claims about AI progress. ​​**Format & vibe:** ​​This is not a lecture it is an interactive workshop designed to help people think clearly about a topic that is increasingly important and moving very quickly. ​​Whether you’re new to AI, casually interested, or deeply unsure what to believe, you’ll leave with a clearer picture of *why* many researchers take superintelligence seriously—and *what’s actually at stake* if we get it wrong.

Hands-on learn how to save life & limb, when mired in the wilderness of an urban disaster zone, travel or rural area far from hospital, or natural area miles from an access point, during the critical minutes or hours before ambulance arrival. Come away with actual do-it-yourself care-giving skill and confidence, and 2-year SOLO certification. Counts as WFR Recertification, too. No prerequisites. YOUR SPOT IS NOT RESERVED UNTIL YOU'VE COMPLETELY REGISTERED AT WWW.SOLOWFA.COM \***Spaces are limited. REGISTER: www.solowfa.com or 434.326.4697** Can't make these dates? Check out more course locations and dates on our website. WHO: Open to the general public, adults & teens with solid attention spans. Know your loved ones are safe wherever they are. WHY: Mired in a disaster zone, travel or rural area far from a hospital, or natural area miles from an access point ... accidents, destructive weather, and terrorism happen, and all-too-often members of a group are not capable of dealing with the emergency. This leads to improper care of the patient, and endangers the entire group. Many recreational accidents are preventable, and improper care of trauma can compound even simple injuries. Very few first aid programs actually address the issues of providing emergency care in a setting where 911 is overwhelmed or not immediately reachable. In this course, classroom instruction and Q&A are interwoven with practical work and problem-solving exercises. Hands-on experience - a most powerful learning tool - during scenarios comprise \~50% of class. TIMING: This is a 2-day class, Saturday and Sunday, 8:00am -7pm each day. Fee: $295 (Earlybird)

Details Location: Crimson Whiskey Bar (Either the downstairs whiskey bar, or main floor bar, TBD) The purpose of Thinkers and Drinkers is to facilitate casual but meaningful and interesting conversations with other people in a face-to-face setting. The topics cover a wide variety of issues and are different for every meeting. While conversations may get heated at times, we ask that all members be respectful of each other and refrain from personal insults. Here's the updated version: *** **Topic: Reasons to Be Excited (A Technology Optimism Round)** It's easy to doom-scroll your way into thinking the world is falling apart. And honestly, some of our recent meetings haven't helped. So this time, we're flipping the script: what technology are you actually *excited* about? This isn't a request for blind techno-utopianism. Skepticism is welcome. But the goal is to spend some time on the genuine wins and promising horizons, because there are more of them than the headlines suggest. Here's a quick tour of some things worth being optimistic about: * **AI in everyday life** — Love it or hate it, AI tools are genuinely saving people hours of tedious work. From coding assistants to writing tools to writing this very event descriptin you're reading now to AI that sits inside your spreadsheets and email, the practical applications are moving faster than most people expected even two years ago. The question is less "will this be useful?" and more "who actually benefits, and when?" * **Clean energy's quiet boom** — Solar and battery storage have had a decade of jaw-dropping cost reductions. The U.S. added more renewable capacity last year than any year on record. It's not fast enough for some, but the trajectory is real. * **CRISPR and gene editing** — In late 2023, the FDA approved the first CRISPR-based treatment for sickle cell disease — a condition that has caused lifelong suffering for millions of people with very few good options. It's the first of what could be a long list of genetic diseases that are now, for the first time, actually curable rather than just manageable. * **Lab-grown meat** — Chicken and beef grown directly from animal cells, no slaughter required. It's real, it's been approved for sale in the US, and while it's still expensive and not yet on your grocery shelf, the cost curves are dropping fast. Whether you care about animal welfare, climate, or just think it's cool, this one is quietly wild. * **SpaceX and the new space economy** — Reusable rockets went from fantasy to routine. Launch costs have dropped by an order of magnitude in 15 years, opening the door to satellite internet in remote areas, new science missions, and yes, eventually humans on Mars (whether or not that excites you). * **Brain-computer interfaces** — Still early, still expensive, but Neuralink and others are giving paralyzed patients the ability to control devices with their thoughts. The sci-fi shelf life on this one is getting shorter. **Questions to Consider:** * Is there a technology you were skeptical about that has actually won you over? What changed your mind? * Which of these feels most overhyped — and which feels *under*hyped? * Are the benefits of new technology reaching people broadly, or mostly concentrating among the already-fortunate? * Is optimism about technology a luxury? Does it depend on where you live, how much money you have, or what you do for work? * What's something small and unglamorous — not AI, not space — that has genuinely made your life better recently?

[The Board Walks](http://www.theboardwalks.com/) are for curious people who love deep conversations. If that sounds like you, **bring a thoughtful topic** and join us for a 5-mile walk (10,000+ steps!). **HOW IT WORKS** **Step 1: Bring a topic** Before you arrive, think of **one** topic you want to explore. A question. A thought that's been on your mind. An obsession you want to geek out on. This is your ticket to the event. **Step 2: Circle up & share** We gather in a circle. Your friendly walk host gives a speech to set the tone. Everyone shares: your name, what you're grateful for, and your topic. That's it. 60 seconds. **Step 3: Walk, talk & float** We walk 5 miles. You naturally drift into conversation with 2-3 people at a time, pulled by topics that spark your curiosity. When you're ready to move on, just say: "I'm going to float!" **Step 4: Feel more alive** Two hours flies by. You're back where you started — but you feel different. More alive. More energized. More connected to yourself and others. That's why regulars join 20+ times. *For more details, read our [Orientation Guide.](https://www.theboardwalks.com/orientation)* **HOW TO BRING A GREAT TOPIC** A great topic = something you're genuinely curious about. Recent topics include: * "What are you passionate about right now?" * "What makes a good friend?" * "What's a belief you used to hold that you've completely changed?" * "How do you want to be remembered?" * "What would you do if money wasn't a factor?" Think of your topic like the dish you're bringing to our conversational potluck. If everyone brings an A+ dish (i.e. energizing, uplifting, expansive), we'll all walk away feeling lighter and brighter. **WHAT TO EXPECT** This isn't a fitness event with casual chitchat. It's a walking think tank where we explore life's big questions together, beyond small talk. *If you're looking for light banter or a standard networking event, this probably isn't the right fit.* But if you crave depth, genuine connection, and conversations that make you feel alive? You'll love it here. **FAQ** * Wear casual athletic attire and sneakers. It's a long walk! * We have multiple first-timers at each event. We work hard to create a welcoming, inclusive, clique-free space. * We welcome people of **all** ages, backgrounds, and industries who align with the [intention](https://www.theboardwalks.com/ground-rules) of this space. * Rain or shine, we've been out here nearly every week since July 2022. If the event is cancelled, we'll let you know. * Dogs, babies in strollers, parents, and friends are welcome — please text/email them the event link so they can RSVP and prepare a topic! **LOGISTICS** * If you'll arrive over 10 minutes late, we suggest skipping the event. It's hard to find us once we start walking, and your host can't answer messages during the event. * This walk is designed for everyone to *move together at the same steady pace* (about 20 min/mile). This format works best when the whole group moves in unison. If you have mobility limitations, we kindly encourage you to find an event better suited to your needs. * Read our [Orientation Guide](https://www.theboardwalks.com/orientation) for full details. * If you enjoy the event, send **[this](http://www.theboardwalks.com/)** to a friend or sign up for our **[newsletter](https://theboardwalks.beehiiv.com/)**. We're in multiple cities with more on the way. 🤠👋 **IF YOU WANT TO GO DEEPER...** [The Board](https://stan.store/ellebeecher/p/the-board) is the next step: a high-trust collective for renaissance people devoted to creating, connecting, and building lives that light us up. * This is a global HQ for people who crave big talk, deep connection, and dream collaborations with people across industries. If the walks feel like a spark... The Board is the fire. Apply [here](https://stan.store/ellebeecher/p/the-board).

The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively. This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way. **YouTube Link** TBA
