Data Art

This month, we'll have a recorded talk, followed by discussion, on API design and single-header libraries. How should we structure and program libraries to impose as few usage constraints as possible? We’ll look at [the STB libraries](https://github.com/nothings/stb) and other examples as case studies. We're still at the West End Library - see the location in the sidebar for details. **Agenda:** \- 2pm \- 3pm: Library discussion \- 3pm \- 4pm: Open\-ended discussions\, presentations\, etc\. \- 4pm \- whenever: We'll go get food nearby\! **What we do** Presentations on lower-level, foundational programming topics, ethical software, knowledge sharing, mentoring, and discussion. **Who we are:** We are all about handmade software. Rather than focus on frameworks, heavy abstractions, and buzzwords - we typically create projects or research topics that build an understanding of foundational computing concepts, essential data structures, and hardware/software interaction. **What to bring?** Bring a laptop, project, or just a curious mind. If you're not sure you're ready to contribute, don't worry: we're all here to share our passions and hone our craft. **If you arrive late:** Please enter the room quietly as to not disrupt anyone that is presenting. You can take any empty seat.

Filipino Combat Systems(FCS) is an organization/system with members from around the world. FCS is based on Tuhon Ray Dionaldo's over 35 years of practicing various FMA (Filipino Martial Arts) styles. He's combine elements of each, into one system that's efficient, fast, concise, and logical. FCS members have extremely diverse backgrounds, and Martial Arts systems.

To help us estimate attendance and to see the venue address, please RSVP on Luma!: https://luma.com/af0yjzz6 *A free, public workshop—no technical background needed* ​Artificial intelligence is no longer just getting better at narrow tasks—it’s beginning to look *general*. Many researchers believe we’re entering the early stages of the **AGI transition**: a period where AI systems start to match or exceed human abilities across a wide range of domains. ​This workshop explores what AGI actually means, how to think about it intuitively (without hype or jargon), and what this transition could mean for your job, your relationships, and your day-to-day life—much sooner than most people expect. ​Together, we’ll explore questions like: ​**What is AGI?** ​How do experts define artificial general intelligence, and how is it different from today’s AI tools? ​**Work & Jobs:** ​Which kinds of jobs are already being automated or transformed—and which ones experts believe are most likely to remain resilient? ​**Human Connection:** ​How is AI starting to replace or supplement roles once filled by coworkers, friends, tutors, therapists, and companions? ​**Robots & the Physical World:** ​What happens when advanced AI is paired with rapidly improving robotics—and which parts of the economy could change next? ​**What you’ll get:** * ​A clear, beginner-friendly explanation of AGI and why it matters * ​Real-world examples of how AI is already reshaping work and social life * ​Live demos that highlight both impressive capabilities and emerging risks * ​Interactive discussion and exercises to test your own intuitions about the future ​Come ready to grapple with one of the biggest transitions humanity may ever face—a shift that could redefine not just how we work, but how we relate to each other, find meaning, and navigate a world increasingly shaped by intelligent machines.

***Join us for a day in an electronics lab, as we attempt to finalize the system, and run scans for atoms.*** We will likely not succeed on our first attempt - but we still plan to put the time in. 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.

ike Turkey Run Park- Pho Lunch, VA Sunday March 8 With winter weather receding, this is a great way to fight cabin fever and head back outside with views of the Potomac. This is a 3 to 4 mile loop hike along the Potomac River just below the American Legion bridge off the GW parkway. The trail is mostly easy and flat, but there are some slightly rocky areas. Be aware that this time of year where segments along the river can be muddy and there are some rocky areas we must maneuver around. Bring a mascot! The park is dog-friendly, but must be on a leash.

Bring your project and join a boisterous group of crafters in first floor of either building.

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.

**Google Analytics Alternatives** Is it finally time to make the switch away from Google Analytics? Two-and-a-half years ago Jason Packer asked this question at Columbus Web Analytics Wednesday. Since then: Google’s Universal Analytics has been sunset, we’ve changed our name to Columbus Data & Analytics Wednesday, and Jason has released two editions of his book “Google Analytics Alternatives”. Fresh off the release of the 2nd edition of his book, we thought it was time to re-open this conversation. While people love to complain about it, GA’s market share has remained relatively constant (at least in the United States). Why is that? You won’t find any complaints about GA4 in this talk, but rather an overview of what’s currently available in the market and how to frame your decision-making process. We’ll also be giving out some free copies of Jason’s book! So even if you’ve got a “GA4Lyfe” tattoo (no judgement), there’s free books to go with the free pizza and beer.
