What3words: https://w3w.co/stick.juices.rings [https://what3words.com/stick.juices.rings](https://what3words.com/stick.juices.rings) Share only your very best, most interesting shots after the field trip, and keep it down to between 5 and 10 photos. [http://www.fairfaxcounty.gov/parks/huntley-meadows-park/](http://www.fairfaxcounty.gov/parks/huntley-meadows-park/) From the parking lot near the visitor center off Lockheed Blvd, there is Cedar Trail which is about a 15-minute hike to the Heron Trail boardwalk. The Cedar Trail goes through a great forest that has some wildlife like deer and many birds, The Boardwalk is where the majority of the wildlife is located. The Group has seen deer, foxes, beaver, snakes, frogs, green tree frogs, huge snapping turtles, and many types of birds including Bald Eagles, Osprey, Marlins, Great Blue Herons, Great Egrets, King Fishers in the marshy wetlands. The boardwalk can become crowded before sunrise. The crowd, notwithstanding, the early arrivals have been rewarded with sightings of foxes and Bald Eagles. There is a point on the boardwalk that splits. The left side features sightings of shorebirds snapping turtles and beavers. The right side leads to one of the smaller overlooks and has several benches along the way. In the wintertime, the Group gets to photograph many migrating ducks, such as Green-winged teals, Northern Shovelers, and Northern Pintails! In the springtime, the park provides bird boxes for the Wood Ducks and Mergansers to lay and protect their eggs until their offspring fledge and leave the nest. The Group then continues around the boardwalk to the right towards the forest where Great Blue Herons and Red-winged Blackbirds are photographed. Next, the Group approaches a two-story overlook complete with benches for the Group to rest and survey the park. Following a brief respite, the Group continues to Marker 8, the end of the boardwalk. At this point, the forest reappears. And on that edge of the wetlands, there are Red-Headed Woodpeckers. This is one of the few places in the Washington, DC area where they live. After a couple of hours on the wetlands, the Group retraces the route by continuing on the boardwalk to the right towards Cedar Trail, past the visitor center onto the parking lot. There is a small pond behind and to the south of the visitors center that frequently has small frogs. While they are a true find to photograph, mosquitoes have been known to swarm at the pond! The north side of the visitor center features bird feeders that attract hummingbirds and other small birds. At the end of this field trip, the Group typically has breakfast at IHOP, 7694 Richmond Highway, Alexandria, VA. 22306.

[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Artemis II and Beyond,”** on how the recent space mission fits into long-term plans for the Moon, with Michael J. Neufeld, retired senior curator for the Space History Department of the Smithsonian’s National Air and Space Museum. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-artemis-ii-and-beyond](https://events.ticketleap.com/tickets/profsandpints/dc-artemis-ii-and-beyond) .] NASA’s recent, spectacular Artemis II mission is a sign that the United States is serious about sending humans to the Moon again. Gain an understanding of how Artemis II fits in both past and planned lunar missions with historian Michael Neufeld, who was lead curator of the Smithsonian’s Destination Moon exhibit. He has taught at Johns Hopkins, Colgate, and other universities, and is the author or editor of nine books dealing with the history of technology. He’ll start by looking at the aftermath of the Apollo program of a half century ago and why it ended only four years after its first lunar mission. He’ll consider why no lasting lunar programs emerged from major announcements by two presidents, George H.W. Bush and George W. Bush, that astronauts would be going back to the Moon and on to Mars. His vividly illustrated lecture will then explore how Artemis is a product of a human spaceflight program that has changed dramatically over the past 50 years. We’ll look at how collaboration with Europe, Canada and Japan became integral to the shuttle and International Space Station programs, and how the rise of new commercial space companies such as SpaceX has enabled NASA to buy both space services and space craft. Both international and commercial partners are involved in the latest Moon efforts, with SpaceX and Blue Origin expected to supply the landers to take astronauts down to a planned base on the Moon’s South Pole. How soon will any of this happen? Probably not as quickly as NASA says, but the specter of a Chinese landing on the Moon by 2030 is one obvious reason to keep things moving along. We’ll look at the sustainability of the Artemis space program for at least the next decade or so. You’ll emerge from the talk with no doubt that exciting days are ahead for space fans. (Doors: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.) Image: The Artemis II mission launch (NASA photo).

**REGISTER AT THE LUMA EVENT PAGE!!!** https://luma.com/27ja5gwl Join us for an exciting talk by Mary Gibbs, Senior Applied Scientist at Relativity. ​ ​**​Agenda:** ​​6:00 - 6:30 PM - Welcome and mingle 6:30- 6:45 PM - Introductions 6:45 - 7:30 PM - Talk 7:30 - 8:00 PM - Wrap up **​​Description:** ​If you have ever shipped a model, watched your metrics improve, and later learned from your users that something was wrong, the metrics were always wrong. You just didn’t know it yet. An evaluation consists of three components, a benchmark, a scorer, and a claim about what a score represents. Each component has its own weaknesses. Benchmarks can suffer from narrow coverage, contamination, or saturation. Scorers are often chosen for ease of automation or computation rather than for their alignment with user outcomes. And the claim connecting a score to reality is rarely made explicit. These gaps compound across the model development lifecycle. When metrics improve, teams treat that as a signal and optimize directly against it, which is how a measurement problem becomes a model problem. This talk maps where evaluations can go wrong, considers counterarguments, and ends with practical advice for building better ones. **​Speaker Bio:** ​Mary is a Senior Applied Scientist at Relativity, tackling data science challenges in the e-discovery and legal tech space. She is also an organizer for Women and Gender eXpansive Coders DC (formerly Women Who Code DC), fostering a community dedicated to empowering women and nonbinary individuals to excel in their careers. Mary's experience spans various domains. She has developed data science solutions related to job search and career progression at Teal, cybersecurity challenges at LiveAction Software, and commercial and government consulting at Mosaic Data Science. Before venturing into the field of data science, Mary conducted and published research pertaining to the cellular and molecular mechanisms underlying neurodevelopment at the National Institutes of Health. In other words, she has dissected and imaged a lot of fruit fly brains. She holds a M.S. in Data Science from The George Washington University and a B.A. in Biological Sciences from Cornell University

In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** TBD
