[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.)

Click here to attend: [https://www.jgoot.com/livestreams](https://www.jgoot.com/livestreams) Sometimes the difference between a decent booking and a great one isn’t more points, more time, or more effort. It’s one simple check. One small decision. One moment most people skip… and pay for later. It’s time for: **The Step Most Travelers Miss (And the 60 Second Solution to Never Miss It Again)** JGOOT Lounge Expert Coach Mira will be live with us to break down what that step is, why it matters more than most people think, and how it changes the way you approach every booking. This isn’t about chasing perfect redemptions. And it’s not about adding more complexity to your process. It’s about removing guesswork. Making faster, smarter decisions. And having confidence that you’re actually making the right call before you click “book.” Mira will walk through: • The step most travelers skip when evaluating a booking • Why “good” redemptions can still be the wrong choice • How to quickly compare your options without overthinking it • What to look for before you commit points or cash • A simple way to make sure you’re getting it right, every time This is the kind of session that makes everything else you’ve learned more effective. Because once you see it, you can’t unsee it. Whether you’ve been booking with points for years or you’re still figuring things out, this will give you a faster, clearer way to make decisions and avoid the mistakes most travelers don’t even realize they’re making. And once you have it, you’ll wonder how you ever booked without it. Click here to attend: [https://www.jgoot.com/livestreams](https://www.jgoot.com/livestreams)

We'll be doing an out and back route, so everyone will just turn around at the halfway time marker. That way we should all start and end at the same time. Free Parking at Courthouse Plaza: The underground garage (http://tiny.cc/OmKZx) is on Clarendon Blvd btwn Wayne and Veitch Sts. (near Strayer/CVS and the AMC Theater). If the first 2 levels on the left are full, you can park on the lower levels to the right. Street and Surface Parking lots should be free in the area as well.

Title: Beyond Cryptography: Geometric Symmetry & Parity Stability Summary: Decoding Chaos: Using Quantum-Inspired Symmetry Metrics to Detect Stealth Attacks in High-Stakes Infrastructure. Agenda: Why symmetry matters after the proof is done. Symmetry as an Invariant Symmetry as a Security Primitive Trust as a Continuous Function Live Thought Experiment Engineering, Implications & Open Questions Move away from traditional bit-matching and discuss "Symmetry Drift." Explain how system states can be modeled as high-dimensional manifolds where an attack represents a geometric deformation.T(t)=f(symmetry stability,parity consistency,temporal coherence) Speaker: Vijay Krishna Vijay is a security engineer focused on runtime observability and symmetry drift in cryptographic systems. He is the founder of Vyapti Resonance and the creator of the Quantum Security Probe (QSP), a telemetry-driven integrity monitoring framework for post-quantum infrastructures. His work bridges theory, engineering, and long-lived system behavior, emphasizing measurable trust over binary verification. Vijay has 9 accredited licenses in Quantum Computing. Career Snapshot: Microsoft → DuPont → Rockefeller Capital Management → Morgan Stanley → New York Life → Founder, Vyapti Resonance Across this trajectory, Vijay has operated at the core infrastructure layer of organizations—cloud platforms, identity systems, distributed compute, reliability engineering, and governance frameworks. His work has consistently involved systems that cannot fail, particularly in regulated financial and insurance environments. This enterprise grounding strongly informs his academic and research outlook: quantum and AI systems must be operable, governable, auditable, and teachable, not merely theoretically elegant.

At this event you'll discover how to better understand and control your subconscious mind, helping you overcome doubts and fears. If you have anger issues, depressions and anxieties. this event will show you how to overcome them.

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.
