**This talk has completely sold out in advance and no door tickets will be available. It also is being staged at Penn Social in DC on March 17th, and tickets remain available then.** [Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Ireland’s Fight for Freedom,”** with Kevin Matthews, assistant professor of history at George Mason University and former London correspondent for Vatican Radio reporting on British and Irish news. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/northern-virginia-ireland-freedom](https://events.ticketleap.com/tickets/profsandpints/northern-virginia-ireland-freedom) .] After centuries of struggle, Irish men and women won their freedom from Great Britain after waging a war that set the pattern for all other independence struggles of the 20th century. But there was a price—the partition of their country, a split setting the stage for the Northern Ireland “Troubles” that didn’t end until 1998. Gain a deeper understanding of Ireland and its history with Professor Kevin Matthews, a historian and frequent Smithsonian Associates speaker who had served as a journalist covering the last stages of the Troubles in Ireland in the early and mid 1990s. He’ll discuss in depth how the Irish won independence in a two-year war between 1919 and 1921, covering topics as the role women played in the conflict, the life and tactics of the revolutionary leader Michael Collins, and the Irish development of “urban guerilla warfare” using small, highly mobile armed units called “flying columns.” Most important, this talk will examine how the conflict between Irish nationalists and Irish unionists led to Ireland’s division and later conflict. From the Easter Rising to the Good Friday Agreement, from Bloody Sunday to Brexit, this conflict has never quite gone away. As the Irish poet, William Butler Yeats once wrote: Now and in time to be, Wherever green is worn, Are changed, changed utterly: A terrible beauty is born. Professor Matthews will explore how the Irish fought to a standstill what was then the mightiest empire in the world and how, more than he could have known, Yeats’ prediction still rings true today.

Valentine's Day might be in the past, but Plato's classic discussion of love and desire, the *Symposium*, is eternal. Join us on March 28 to discuss this famous work, which features Socrates, Alcibiades, and other important Greek figures at a drinking party where things quickly turn philosophical. Feel free to bring whichever translation you prefer. Instead of our usual location, we will meet in the Woodridge Neighborhood Library in **Conference Room A**. Ask at the front desk if you need help finding us. See you there!

Join us to discuss Jane Austen's Bookshelf: A Rare Book Collector's Quest to Find the Women Writers Who Shaped a Legend, by Rebecca Romney. We will be meeting in the food court, look for the table top sign with our group name. The book discussion will begin promptly at 3. If you’d like to purchase food/beverage, please plan on arriving early to do so.

Many popular movies about flying machines bear the title “Drones,” but this isn’t one of them. No, this is a little-known gem about love in the workplace possibly leading to the destruction of planet Earth. Witty writing, solid acting, and slick direction all work together in this movie like bees in a hive, which coincidentally is the point of the title. The cubicle-bound employees of a vast corporation attend to their various tasks, each contributing to the productivity of the whole. But wait – is one of these workers not like the others? And if so, what is this person’s true agenda? When the answers to these questions arrive, the story gets hilariously crazy. The R rating is earned strictly by occasional rude language in this dialogue-driven production, and bluntly your host thinks PG-13 would have been sufficient. ■ Title — *Drones* ■ Director — Amber Benson, Adam Busch ■ Cast — Angela Bettis, Jonathan M. Woodward, Samm Levine ■ Rated R for language ■ ©2010 \| 1h 38m \| Comedy\, Fantasy ■ Distributed by Quiver Entertainment

We typically go out to lunch afterwards at Fat Pete's, a BBQ place which also has salads, pizza, and other non-BBQ options. PJ, the owner, has personally told me to call him and let him know when we're coming so he can sit us in a sensory-friendly space.

📚 Do you love reading, but wish you had a structure and a community to share your insights with? Join our small circle of curious minds (just 4 members per gathering) as we come together for an hour of focused reading—in the calm setting of a library or the cozy atmosphere of a café. Here’s how it works: First part: Quiet reading on your own—bring a book you’re exploring, whether it’s philosophy, history, psychology, literature, or anything meaningful to you. Second part: We regroup and each person shares key takeaways, insights, or questions sparked by their reading. This sparks a structured yet free-flowing conversation around ideas, perspectives, and personal reflections. Why join? Add structure to your reading habit. Discover new books, authors, and ideas through others’ choices. Build real connections by sharing and listening deeply. Socialize around something meaningful instead of small talk.

We will meet outside as long as the weather is nice. If not, we will move inside. Look out for a comment the morning of each meeting with our exact location. As we are meeting in person, please remember to bring something to read as we usually spend some time sharing our current reads and/or reading when meeting in person. As a reminder, there is no assigned reading; please bring whatever you are currently working on. This group is super casual, sometimes we read and sometimes we talk the whole time. **** NO SHOW POLICY: Due to the high number of members on the waitlist recently we are having to reinstate our no-show policy. If you sign up and no-show to 2 events you will be removed from the group. Reminders are provided weekly to change your RSVP to allow those on the waitlist a chance to come to the meet-up, no 3rd chances with be given. Please be considerate to your fellow members. Thank you! I look forward to reading you!

**Join us in Falls Church for conversations that go beyond small talk.** Higher Grounds – Falls Church is where this growing network of gatherings began: a space for thoughtful, authentic dialogue about what matters most.

There’s no set leader or rigid agenda—just a shared commitment to listen as much as we speak. We start with brief introductions focused on what makes you *you* (not your LinkedIn bio), then dive straight into whatever is on people’s minds.

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.

**Google Analytics Alternatives** Is it finally time to make the switch away from Google Analytics? Two-and-a-half years ago Jason Packer asked this question at Columbus Web Analytics Wednesday. Since then: Google’s Universal Analytics has been sunset, we’ve changed our name to Columbus Data & Analytics Wednesday, and Jason has released two editions of his book “Google Analytics Alternatives”. Fresh off the release of the 2nd edition of his book, we thought it was time to re-open this conversation. While people love to complain about it, GA’s market share has remained relatively constant (at least in the United States). Why is that? You won’t find any complaints about GA4 in this talk, but rather an overview of what’s currently available in the market and how to frame your decision-making process. We’ll also be giving out some free copies of Jason’s book! So even if you’ve got a “GA4Lyfe” tattoo (no judgement), there’s free books to go with the free pizza and beer.
