**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. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.) Image: Members of the Irish Republican Army’s West Connemara Flying Column in 1921.

**To receive future event updates, register on Luma:** **[https://luma.com/6qii7007](https://luma.com/6qii7007)** Let's discuss a podcast by Anders Ericsson, author of the renowned book "Peak: Secrets from the New Science of Expertise". Anders demonstrates that talent is overrated and peak achievement is dependent on a specific type of learning called "deliberate practice", and that your skill in any area is a function of the quantity and quality of “mental representations” you have for that activity. We explore the science of learning and of skill mastery -- how it happens, and how to do it. **Please watch this YouTube video (try 1.25x speed) before joining the discussion:** [https://www.youtube.com/watch?v=qiBne5EGBQ8](https://www.youtube.com/watch?v=qiBne5EGBQ8) If more than 8 people join the discussion, we will break out into smaller groups. **(max 8 people per group)** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- 1. **Mastery requires focused quality over mere repetition. How can we ensure our daily efforts are intentional enough to foster genuine growth?** 2. **Effective mentors provide the roadmap for stretching our abilities. How might we better identify the guides who can point out our hidden obstacles?** 3. **Immediate feedback loops are essential for identifying and correcting technical errors. How can we build systems that provide the rapid insights necessary for our collective improvement?** 4. **Peak performance often requires unlearning habits that limit our ultimate potential. What fundamental methods could we refine to ensure our foundations support world-class excellence?** 5. **Growth occurs when we consistently set goals just beyond our current comfort zones. How do we determine the ideal balance between manageable challenge and productive discomfort?** 6. **Elite performance is sustained through intense concentration followed by restorative rest. How can we better value recovery as a vital component of our highest achievements?** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- To provide an enjoyable experience for fellow participants, here are three ground rules during discussion events: 1. Step up and step back. (If you feel that you’ve been talking too much, step back to listen more. If you feel that you’ve been relatively quiet, step up to share your perspective or ask a question) 2. Listen to understand, not to respond. 3. Be open-minded and value differences.

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.
