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.

Friday night Greenbelt International Folk Dancing has gone "virtual". As we all practice good social distancing, many in our folk dance community are feeling the absence of our usually scheduled local dances. In response, please join us for the Greenbelt Virtual Folk Dance Session. Let’s keep dancing! • Connect and dance in our own homes • Watch hosts leading familiar dances • See each other; listen and dance to our favorites How: We will be using the ZOOM video conferencing app to share music and live videos of the leaders and each other. This can be used on a desktop, laptop, or smartphone. What to Expect: Your hosts are Linda Mansdorf, Vita Hollander, Ben Hole, and John Robinson. Collectively they will play 25-30 dances, which should approximate the number of dances normally done on a Friday night in-person event. The hosts will do a quick teaching or demonstration of the steps to some of the dances that may be less familiar to you or just as a refresher, but the session is not designed as a workshop, so the majority of the evening will be spent playing dances that many of us already know and love to do. How To Join Us: Each week we will send an email with the Zoom Meeting link ID. Make sure John Robinson knows you would like to receive this email with the link.

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. For more info and maps (see side links): [https://www.nps.gov/gwmp/planyourvisit/turkeyrun.htm](https://www.nps.gov/gwmp/planyourvisit/turkeyrun.htm) What to Bring: Good hiking shoes Water Meet: 9:00 am Where: Parking Lot C-1. (First parking lot when entering park. See map at link below for details) Park Trail Map: [https://www.nps.gov/gwmp/planyourvisit/upload/Corrected-Turkey_Run_Park_Trail_Map_11242023_508c.pdf](https://www.nps.gov/gwmp/planyourvisit/upload/Corrected-Turkey_Run_Park_Trail_Map_11242023_508c.pdf) Departure: 9:10 sharp. We should return to the parking lot no later than 11:15 am. For those interested, we can later head over to nearby Pho 75 (1721 Wilson Blvd) for a great hot pho - one of the best in the area. **Note: Cash Only!** **In the comments section please indicate if you need a ride. If you are coming by car and wouldn’t mind picking someone up at a convenient metro stop, please indicate how many people you can take. Hopefully we’ll have enough room for everyone. I can pick up three at the Braddock Road metro (yellow), located in Alexandria, VA. Or, I can pick up folks at Rosslyn metro (orange/blue). Carpoolers, please chip in generously for gas.** Note: This event is cross-posted with other Meetup groups.

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.
