Join us for another lowkey writing session! Bring your laptop, iPad, or notebook so that you can get some words down! We will start around 6:00 as people filter in. Writing, chatting, and casual introductions will go on until 6:30 as people arrive and grab food and drinks, when we will do a round-table to introduce ourselves, our genres and writing styles, and what we are looking for from the group. After that, we can buckle down to do some writing and make ourselves be productive! I will try to snag the big community table to the right of the registers at Tatte, or sit against the back wall with a couple of tables pulled together, so you can look for me there. I'll post in the comments when I arrive, so feel free to check there or message me if you are feeling lost or having difficulty finding the group. I'll look forward to meeting you all! Our next workshop will take place on the Monday following this one, so look forward to that, as well!

It's Indie Dev Night! Bring your games that you've made, your game idea, or just your passion for game development! This is an informal event to talk game development with like-minded folks. We'll be hosting this IN PERSON at the MLK Jr. Library in room 401-F Closing Time at the library: 8:30 PM

[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Wink, Nod, Kill,”** a look at implicit calls for violence and other speech that leads to bloodshed and threatens democracy, with Kurt Braddock, assistant professor of communications at American University and expert on terrorism. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-wink-nod-kill](https://events.ticketleap.com/tickets/profsandpints/dc-wink-nod-kill) .] Over the last decade, President Donald Trump and many of his allies have used language that implicitly advocates for the use of violence without directing it outright. From telling the Proud Boys to “stand back and stand by” to suggesting that legal acts of Democratic lawmakers should be “punishable by death,” Trump has consistently suggested that violence is a viable means of addressing political grievances. Support for political violence—implicit or explicit—goes beyond the sort of spirited debate and disagreement upon which the American experiment was founded. It represents a gray area in the connection between violent language and violent acts, an area that Kurt Braddock has spent years studying. Learn about research on the connection between real bloodshed and coded language, dogwhistles, and implicit calls for violence with Dr. Braddock, who has conducted research on communication and terrorism for several national and international organizations, including the U.S. Department of Homeland Security, the U.S. Department of State, and the United Nations Office of Counter Terrorism. Professor Braddock will give his audience a firm grounding in the concept of “stochastic terrorism,” or political violence spawned by vague calls to violent action. Tapping into decades of research on communication and decision-making and accounts of specific violent acts inspired by implicit orders, he’ll show us that the threat posed by implicit calls to violence is real. He’ll discuss whether implicit calls for violence represent a “new” form of political communication protected by the First Amendment, and he’ll describe the real-world dangers posed by these kinds of statements. Among the questions Dr. Braddock will tackle: Why do politicians use this language if they can reasonably assume that someone may be motivated by it to hurt someone else? Perhaps most importantly, what can we do about it, especially given the sacrosanctity of the First Amendment? His talk promises to give you a much more sophisticated understanding of recent events and a clearer sense of what might lie ahead. (Door: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.) Image: Right-wing pundit and podcaster Steve Bannon routinely uses violent rhetoric. (Photo by Nordiske Mediedager / Creative Commons. )

The second section will focus on the results obtained by analysis of the bouguer anomaly map data taken from the best available public dataset (GGMPlus), with an emphasis on specific locations that are especially prominent anomalies, what geology and geophysics tells us about what the causes of these localized anomalies may be, and (time permitting), a brief foray into some of the unanswered scientific questions that remain regarding the cause of certain localized anomalies.* *\***We're getting a jumpstart to Spring Cleaning this year as well.\**** **On March 11, we will have GeoDC's first-ever Geo-Swag Swap.** * **If you've been to any conferences or trainings lately, you may have found yourself wondering 'how in the WORLD did I accumulate so much stuff?'** * **Bring your unused or lightly used Geo Themed SWAG to Sudhouse DC on the 11th.** * **The Swag Swap table will be by the staircase, right as you enter into the event space on the 3rd floor.** * **Please take what you need/want from the table; all unwanted items will be donated or recycled** ***-You do not need to bring Swag to particpate.*** ***\- Examples of Swag: notebooks\, mousepads\, pint glasses\, tote bags\, pens\, pins\, stress balls\, decals\, lens cleaners\, rulers\, magnets\, laser pointers\, lip balm\, etc\.*** **Looking forward to seeing everyone next week!**

In March of 2026, the long-time staple of Kubernetes ingress controllers, ingress-nginx, will stop receiving security patches and regular updates. For many Kubernetes operators, this is a forcing function for us to migrate to a new solution that supports the newer Gateway API. The ecosystem of solutions in this space is large and complex, and operators find themselves weighing a myriad of options. In this talk, I hope to answer many questions that we have had to answer in this space, such as: * What are the advantages of Gateway API over the Ingress API? * Which Gateway API Solution should you use for different scenarios * Why not simply migrate to another ingress controller? * Where does the AWS Load Balancer Controller fit in this new ecosystem? * What does support for WAF, ALB, NLB, etc. look like going forward? **Timeline:** **6:00 PM** \- Doors Open\. Please be prepared to show ID that matches your registration\. **6:30 PM - 7:30 PM** \- Speaker **7:30 PM - 8:00 PM** \- Networking **8:00 PM** \- Event ends\. Conversation continues at Highline for anyone interested\.

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.
