[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“The Secrets of Runes,”** on the origins, development, and interpretation of the runic script, with Lilla Kopár, runologist and a professor of medieval literature and culture at Catholic University. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-runes](https://events.ticketleap.com/tickets/profsandpints/dc-runes) .] The fame of runes outshines that of any other ancient script. They can be found not just on Viking Age rune stones, but on Bilbo’s door and as the Bluetooth logo on your cell phone. Runic script is commonly associated with magic, used by modern practitioners of neopaganism, and in recent decades has captured the imagination of filmmakers and video game designers. Yet most of us know little about the historical origins of runes and have no clue how to read or use them. Come to Penn Social to get schooled on runic script with the help of Lilla Kopár, a veteran scholar of runes who has earned a following among Profs and Pints fans by giving fantastic talks on medieval monsters and Norse mythology. As someone who has carried out extensive field research on runes, published several articles on runic objects, and even appeared on the History Channel commenting on runes in America, she’s exceptionally qualified to introduce you to runology and the fascinating things that runes tell us. Dr Kopár will discuss the development of runic script from its humble origins on the borders of the Roman Empire in the first or second century CE, through its popularity in the Viking world, to its use and misuse in modern times. She’ll discuss how runes are a set of related alphabets that underwent changes over time and she’ll describe what inspired changes in this writing system and where and how runes were used in the medieval period. Her richly illustrated talk will highlight some of the most intriguing objects with runic inscriptions, from humble bone fragments to impressive rune stones, and offer insight into the scholarly methods of deciphering and interpreting runic inscriptions. We’ll also look at the function of the runic script from simple practical notes and memorial inscriptions to cipher-runes and magic. The most fun might be the in-class assignment, which will involve reading a few runic inscriptions and writing your name and other words in runes. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.)

**\* This is an in-person event** Most people only experience finished products. Very few get the opportunity to work on something before it's finished when it can still be shaped. This is one of those opportunities. Karen Hold, Director of DT:DC, is currently developing a new innovation skills workbook with Jeanne Liedtka, based on over a decade of teaching and working with leaders across organizations, universities, and the DT:DC community. Her work focuses on the five statistically validated skills that help people develop as innovation leaders. This workbook builds on her work in design thinking and innovation education, including programs at the University of Virginia Darden School of Business, École des Ponts Business School (Paris and Casablanca), and Boston College. For this session, Karen will share a draft chapter of her new workbook for live testing. This is not a polished workshop. It's a working lab. You won't just participate. You will help shape the material itself. What We’ll Be Testing: * Whether the exercises actually help people think differently * Where the material is clear and where it breaks * What feels useful vs. what needs to be reworked This is the kind of work that typically happens behind closed doors. **What You'll Do** Working in small groups, you will: * Work through exercises from a draft chapter of the workbook * Apply them to real situations and ideas * Share feedback on what is clear, confusing, or missing * Help identify how the material can be improved You’ll get: * Early access to work that is still being developed * A chance to influence how this material evolves * Practical tools you can immediately apply * A behind-the-scenes look at how skill-building experiences are designed This is a rare opportunity to be part of the process, not just the outcome. Join us if you want to be part of something early, unfinished and actively evolving. No prior experience is required. **About Karen Hold** Karen Hold is the founder of Experience Labs and Director of DT:DC, one of the world's largest innovation communities connecting founders, designers, policymakers, and changemakers. Her work sits at the intersection of teaching and real-world application. She works with Fortune 500 corporations, federal government agencies and non-profit organizations, helping teams strengthen how they think, make decisions, and move ideas forward. She teaches in graduate and executive education programs, including at the University of Virginia Darden School of Business, École des Ponts Business School (Paris and Casablanca), and Boston College. Karen is a co-author of *Experiencing Design – The Innovator’s Journey*, and her work focuses on developing the skills that enable individuals and organizations to navigate complexity and create meaningful change.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.
