Physical Security

**This talk has completely sold out in advance and no door tickets will be available.** [Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“The Ballistic Missile Defense Question,”** on the operation of a controversial defense system and the debate over its use, with Dean Wilkening, a physicist and defense system researcher formerly at the Johns Hopkins Applied Physics Laboratory, the Lawrence Livermore National Laboratory, Stanford University’s Center for International Security, and the RAND Corporation. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://www.ticketleap.events/tickets/profsandpints/dc-ballistic-missile](https://www.ticketleap.events/tickets/profsandpints/dc-ballistic-missile) .] Ballistic missile defense has been a contentious political issue in the United States, especially after President Ronald Reagan’s 1983 speech calling for a “Star Wars” style barrier to Soviet nuclear weapons. Ballistic missile defense is also among the most expensive items in the Pentagon budget for research, development, test and evaluation, with funding estimated at $10.6 billion in 2026. Most recently, ballistic missiles have been making headlines as a result of Iran’s recent ballistic missile attack against Israel, Russia’s ballistic missile attacks against Ukraine, and President Trump’s call for America to be defended by a “Golden Dome” similar to Israel’s Iron Dome system. But is relying on ballistic missile defense (BMD) systems practical and wise? Hear that question tackled by Dean Wilkening, who recently retired from the Johns Hopkins Applied Physics Laboratory, has spent much of his life studying a range of defense matters such as hypersonic weapons and ballistic missile defense, and who has published extensively and advised national boards and government agencies on his findings. Dr. Wilkening will discuss the technology underlying BMD systems, which seek to use precision guided munitions to essentially “hit a bullet with a bullet” to thwart attacks. You’ll learn about the support systems, including sensors and command and control systems, critical to making it all work. Then he’ll give an overview of the debate over ballistic missile defense systems, typically split along partisan lines. We’ll look at the evolving missile threat, which includes both conventional and nuclear ballistic missiles as well as hypersonic weapons, and the potential for armed conflict with Russia, China, North Korea and Iran. Dr. Wilkening will look at whether BMD systems meet the test of working technically, being able to survive attack, and being cost-effective at the margins. Finally, he’ll take on the big-picture question of whether ballistic missile defense is inherently “destabilizing.” Do they stimulate arms races? Do they actually make nuclear war more likely?

***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! We want to continue with full systems testing, after the powerline component repair - and overall just 'get back into it'. Let's resume repeated full end-to-end testing cycles and continue to iterate our design and resolution. 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

THIS CLASS IS OFFERED THROUGH CAPITAL PHOTOGRAPHY CENTER **PLEASE REGISTER WITH CAPITAL PHOTOGRAPHY CENTER, NOT MEETUP!** https://capitalphotographycenter.com/classes/class/2026-02-01-photographic-composition-essential-techniques The composition of a photograph is the single most important element a photographer uses to convey an artistic statement. What’s included, excluded and the arrangement of elements within the frame is all part of composition. This class will teach you techniques to improve the composition of your photos with hands-on shooting experience coupled with feedback. Join instructor Michael Koren as you learn about composition in the Postal Museum and Union Station. The class begins with a lesson and viewing examples of compositional techniques from master photographers to help you when composing your own photographs. We'll then go to specific locations to practice those composition techniques. Afterwards, participants will have free time to photograph all the museum has to offer. We’ll follow up with a gentle critique and feedback of your best work of the day. This class is about "seeing" stronger images. Any camera will do from DSLRs to mobile phones. If you *are*bringing a DSLR or mirrorless camera, lenses in the range of 18-135 would work well. No tripods allowed for this class. Questions can be directed to Marie Joabar at info@capitalphotographycenter.com. Class limit: 8-10 *** **THIS CLASS IS OFFERED THROUGH CAPITAL PHOTOGRAPHY CENTER** https://capitalphotographycenter.com/classes/class/2026-02-01-photographic-composition-essential-techniques

I love my job and one of the main things I do is help customers get going with any of the data technologies at Microsoft. Right now there are a lot of my customers asking about Microsoft Fabric. It's hard to weave across all the shiny new options across the Fabric landscape, let alone figure out where it fits into your organization. In this session we'll focus on answering one question - how can I get data into Fabric? We'll talk through the "it depends" options and see some of the options in live demos.

OWASP is ending use of Meetup, so I built an eventbrite for the event. https://www.eventbrite.com/e/ai-development-risk-case-studies-and-how-agentic-ai-is-the-future-of-appsec-tickets-1981450622150?aff=oddtdtcreator AI is transforming how software is designed, developed, and deployed, dramatically accelerating velocity while introducing new categories of risk. As organizations adopt AI-assisted coding, autonomous agents, and increasingly complex model interactions, traditional application security approaches struggle to keep pace. This talk examines emerging AI-driven risks through real case studies from the field, highlighting issues such as insecure code generation, data-leakage pathways, model manipulation, and evolving supply-chain threats. We will explore how engineering teams must adapt their people, processes, and governance models to secure AI-augmented development workflows effectively. The session will then introduce agentic AI as the next evolution in application security—autonomous systems capable of continuous analysis, multi-step reasoning, and real-time remediation. Attendees will learn how combining agentic AI with modern practices can reduce developer friction, improve coverage, and create a future-ready application security strategy designed for the demands of AI-native software development

**Important note about the retirement of the OWASP Meetup platform** Fellow OWASP Toronto members, We are making an important announcement regarding an upcoming transition. The OWASP Foundation has announced that they will be retiring their Meetup Pro subscription effective January 31, 2026: https://owasp.org/blog/2026/01/13/retiring-meetup.html This means that our OWASP Toronto Meetup group may be removed in the coming days. We understand this may be short notice, so we want to make this announcement before we lose access. You are an important part of our chapter community. Many attendees I have spoken to have discovered OWASP Toronto via Meetup. To continue engaging with the community while using a platform that enables discoverability, we will moving to the [Evenbrite](https://owasp-toronto-chapter.eventbrite.com/) for publishing our events.
