DIY (Do It Yourself)

Want to mess with some electronics? Or perhaps contribute to HacDC's main group project? HacDC's latest event brings hardware projects to the community. We will focus primarily on the main project (Space Blimp!) but please feel free to bring some of your own projects to show off and work on!

Have you been thinking about trying self-defense training, but do not want a loud, aggressive, or overly competitive environment? This free intro class is a simple way to get started. Maryland Systema offers practical self-defense training for adults in Takoma Park with a focus on movement, awareness, breathing, posture, and calm under pressure. This class is designed for beginners and first-timers who want real-world self-defense training in a welcoming setting. You do not need experience. You do not need to be in top shape. You do not need a martial arts background. You just need to show up ready to learn. This is not a sport-based class built around winning points, memorizing routines, or trying to look impressive. It is a more practical approach to adult self-defense training that helps you stay balanced, aware, and functional when things feel uncertain. If you have been searching for self-defense classes in Takoma Park, beginner self-defense near you, or practical self-defense training for adults, this class is a good place to start. **What you will work on** * Breathing and staying calm under pressure * Movement that improves balance and mobility * Awareness and posture * Simple partner drills * Practical self-defense training for beginners **Who this class is for** * Adults new to self-defense training * Beginners looking for a low-pressure class * People who want practical self-defense instead of sport martial arts * Adults in Takoma Park, Silver Spring, Rockville, and nearby areas looking for realistic self-defense classes **What to wear** Please wear comfortable workout clothes. No uniform is required. **Why start with this class** This free intro class gives you a chance to experience the training, meet the group, and see whether Maryland Systema is the right fit for you before joining regular weekly classes. **RSVP** Reserve your spot and come try a beginner-friendly self-defense class in Takoma Park.

We will have open shop hours for anyone to bring their bikes to work on or need help fixing your own bike. We will also have bikes that need to be fixed so you can learn if you like. We will need everyone to sign in when arriving and sign out when leaving so we can keep track of volunteer hours and shop times. Suggested donation of $15 per hour for use of tools and space would be appreciated. Thank you!

Title: What Is Progress? Knowledge Aggregation, Living Textbooks, and the Automation of Scientific Discovery Date: June 20 2026 Noon - 14:00 EDT Summary: Our collective knowledge infrastructure — the textbooks, professional training resources, and literature syntheses that define what professionals across disciplines believe to be true — is quietly accruing a structural liability. Compounded confirmation bias, stacked citation-by-citation into the foundations of formal knowledge, means that breakthroughs can take decades to reach the classrooms, clinical workflows, and decision-making frameworks where they matter most. Meanwhile, the deepest friction is rarely acknowledged: before any field can build meaningful consensus on "why" or "how" a phenomenon occurs, it must first establish honest, consolidated agreement on "what" has actually been observed. That prior step is routinely skipped, assumed, or fragmented across siloed literatures that never cross-pollinate. This talk introduces a framework called "Knowledge Aggregation" — with two distinct but complementary ambitions. The first is descriptive transparency: algorithmically mapping what has been said, measured, and documented across a problem space, without imposing causal interpretation or narrative. The second traces the boundary between empirical observation and explanatory claim, building systems that can separate the "what" from the "why/how" — because consensus on mechanism cannot be meaningfully constructed until consensus on phenomenon is first established. Both ambitions are now within reach. By composing tools already at our disposal — large language models, classical NLP pipelines, public data repositories, and engineering-grade automation frameworks — it becomes possible to model knowledge itself, rather than merely imitate individual experts. One concrete expression of this is automating the writing of living textbooks: compressing the lag from bleeding-edge discovery, through replicated evidence, all the way to professional training resources. But the deeper aspiration reaches further — toward automating the discovery of scientific insights that have never previously been conceived, by systematically surfacing hypothesis combinations that no single siloed researcher would have had the cross-disciplinary vantage point to even ask. Drawing on ongoing systems biology and computational research — with ME/CFS research demoed as a use case for what siloed, fragmented knowledge infrastructure costs in practice — this talk maps the conceptual architecture, the real-world friction, and the data science toolkit for building it. Speaker: As a systems biologist at heart, Sam specializes his biomedical research on interactions and connections in biology - rather than just one domain of expertise. He wears many hats and collects skill sets across disciplines, with degree studies and industry experience acquired across Chemical Engineering (BSc), Bioinformatics (MSc), Systems and Synthetic Biology (M2), Biomedical Sciences (MSc), and beyond. Even more important to him than niches or fields of work, comes down to the synergistic approaches that allow us to move beyond reductionism. The notion that a question can only allow for one answer, is inherently reductionist. By resisting many norms in science and engineering which can get overly reductive, his current role as Principal Investigator of Research for DMV Petri Dish (501(c)(3) non-profit local to the DMV region) embraces computational frameworks that aide scale-up and automation - not only around the processes which already exist with established workflows, but also taking a keen interest in attempting and accomplishing ambitions which have never been perceived to be possible previously. Sam carries a passion for the synergy of computational biology - fused with wet lab validation. This way, one can build a beautiful knowledge base in the theoretical sense, and then test to see if said computational prediction might actually be able to stand in the real world with wet lab validation. Translational modeling starts to become possible once biological experiment design can be iteratively looped alongside computational model design, optimization, and analysis - empowering the design of a better wet lab experiment, followed by a better computational model, back and forth until science is done!

It's my birthday! Let's craft. We'll be meeting at Quill and Crumbs at the Shakespeare Folger Library in SE. The Shakespeare Folger Library is about 3 blocks from the Capitol South metro. Head up First as you get out of the station, pass the Library of Congress and the Capitol, turn right on East Capitol, and the Folger is on the right. The entrance is around the side, not through the front of the building. Head upstairs to the cafe and we'll be at the tables at the back. Bring your own cross stitch, knitting, crochet, or other portable craft.

Grab a drink or some food and get to know each other. This is our first event and we can take it slow. I’d love to meet everyone and hear if there’s anything you like to get out of the group. Looking forward to meeting you all!

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD
