Machining

***In Person Location:*** Rockville Library, second floor meeting room (Collaboration Room 3). We are experimenting with a new virtual join link - [https://meet.jit.si/mocomakers](https://meet.jit.si/mocomakers) If you can make it in person, that's always recommended! Let's resume repeated full end-to-end testing cycles and continue to iterate our design and resolution. We are getting close. 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. Does it sound hard? Perhaps.. However! I have every confidence that we are now operating at a level were we can take on this mean, cross-functional project. We continue to build on our past successes, and a key technology we previously applied was increasing the signal of small voltages using OpAmps - which we did during our custom pH Probe project - [https://www.mocomakers.com/ph-probe/](https://www.mocomakers.com/ph-probe/) \- That technology is exactly what we need to get this machine working\, and at a high precision\! 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 have a bit over $2,000 in materials costs, so if you want to sponsor this project, and get banners at events with 20K attendees, and access to our email broadcast of 30K members, please contact matt@mocomakers.com We are also open to university, lab, or community partnerships so feel to reach out if you want to be part of this project. Together, we can do incredible things. ***In Person Location:*** Rockville Library, second floor meeting room (Meeting Room 3). To Join Virtually: https://meet.jit.si/mocomakers

Everyone’s heard of book clubs where the group reads the same thing and gets together to discuss, which is great… if you have time and interest in whatever’s chosen. This is a different type of book club where you bring whatever you’re currently or recently reading (or just a book you’re super excited about) and talk about it with fellow book lovers. We’ll start with people arriving/ordering food between 615-645, then go around and introduce ourselveslves and give a very brief synopsis of what we’re reading and why we’re excited (or not!) about it. Then devolve into informal conversations until people need to head out. The goal Is to create community and connections in a group of strangers - to facilitate this please make sure you have at least a clear first name on your profile. Upside on Moore has a great selection of food you can order from your phone or at the kiosks. There’s also a bar with happy hour, something for everyone! Arrival tips: if you’re taking the metro, it’s the building above the Rosslyn exit. If you’re driving, you can park in the public lot under the food hall (entrance from the one way bus street) and validate parking after 6!

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Ireland’s Fight for Freedom,”** with Kevin Matthews, assistant professor of history at George Mason University and former London correspondent for Vatican Radio reporting on British and Irish news. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/northern-virginia-ireland-freedom](https://events.ticketleap.com/tickets/profsandpints/northern-virginia-ireland-freedom) .] After centuries of struggle, Irish men and women won their freedom from Great Britain after waging a war that set the pattern for all other independence struggles of the 20th century. But there was a price—the partition of their country, a split setting the stage for the Northern Ireland “Troubles” that didn’t end until 1998. Gain a deeper understanding of Ireland and its history with Professor Kevin Matthews, a historian and frequent Smithsonian Associates speaker who had served as a journalist covering the last stages of the Troubles in Ireland in the early and mid 1990s. He’ll discuss in depth how the Irish won independence in a two-year war between 1919 and 1921, covering topics as the role women played in the conflict, the life and tactics of the revolutionary leader Michael Collins, and the Irish development of “urban guerilla warfare” using small, highly mobile armed units called “flying columns.” Most important, this talk will examine how the conflict between Irish nationalists and Irish unionists led to Ireland’s division and later conflict. From the Easter Rising to the Good Friday Agreement, from Bloody Sunday to Brexit, this conflict has never quite gone away. As the Irish poet, William Butler Yeats once wrote: Now and in time to be, Wherever green is worn, Are changed, changed utterly: A terrible beauty is born. Professor Matthews will explore how the Irish fought to a standstill what was then the mightiest empire in the world and how, more than he could have known, Yeats’ prediction still rings true today. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.) Image: Members of the Irish Republican Army’s West Connemara Flying Column in 1921.

## Hey Columbus WIP peeps! ## Are you ready for an event that actually gives you what you asked for?? **\-\-\-\-\-\-** **A Small-group coaching conversations for women in product navigating growth, leadership, and career decisions.** **March 10 \| 5:30–8:00 PM** **Rev1 -- NEW SPACE** **330 Rush Alley #100** **Parking Options:** • **Rev1 at The Peninsula** • **Starling St. Garage South** – 377 W. Capital St. • **LAZ Parking (COSI)** – 50 Belle St. • **LAZ Parking Limited** – 375 W. State St. • **Veterans Memorial Lot** – 300 W. Broad St. • **Metered Street Parking** **What moves are you making?** A promotion you’re working toward. A role change you’re considering. A bigger leadership opportunity. A conversation that needs to happen. A decision that’s been sitting in the back of your mind. For our Q1 Women in Product Columbus event, we’re creating space to actually work through those moments. **Making Moves** is an evening of focused, facilitated coaching conversations with experienced mentors from our local product community. This isn’t a panel. It’s not passive networking. It’s small-group dialogue designed to be thoughtful, practical, and worth your time. Here’s how it will work: • You’ll choose a topic that reflects what you’re navigating right now • You’ll join a small coaching circle (5–7 participants) • Each circle is led by a mentor who has lived experience in that area • We’ll run two rounds so you can go deeper or explore a second conversation ### Coaching Topics: • Communicating the Value of Your Work (or Team) • Career Transitions & What’s Next • Growing Into Leadership • Staying Relevant as Technology (and AI) Changes • Getting Alignment and Decisions from Leadership Our goal is simple: you leave with clearer thinking, practical perspective, and at least one next step you feel confident about. Space in each circle will be limited to keep conversations meaningful. If this sounds like the kind of room you’ve been wanting to be in, we’d love to see you on March 10. RSVP here!

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.

Projects that are over budget, delayed, or that fail to scale past the POC phase are very common. In many of these scenarios, choosing the right approach can be as critical as the solution itself. Should you build a tailored machine learning model, leverage the power of large language models (LLMs), or integrate with AI copilots? Each option has unique strengths, trade-offs, and resource requirements, and the key to success lies in aligning your choice with your business goals and technical constraints. In this talk, we will go beyond the basic concepts and definitions to provide a practical guide that allows attendees to navigate these decisions through real-world case studies. We will examine scenarios in which different AI paradigms were chosen, discuss the factors that influenced those decisions, and outline the process for evaluating needs, constraints, and outcomes. From assessing data availability and team expertise to balancing cost and scalability, you'll gain insights into the critical considerations that guide the selection process. By the end of this session, you’ll have a clear process for determining whether machine learning, LLMs, or copilots are best suited to your AI challenges and understand the resources and strategies needed to bring your chosen solution to life. This talk is ideal for decision-makers, technical leads, and innovators seeking to demystify AI implementation and maximize the impact of their investments.
