Looking for a new skill? Want to seem mysterious when people ask about your hobbies? Enjoy puzzles? Lock picking might be right for you! Is this legal? Yes! Is it fun? Yes! The meeting is very casual, come and go as you please. We meet in the upstairs area of Board Room. No payment, skills, tools, or RSVP necessary. If you can make small precise movements with your hands, you can learn to pick locks. Introductory talk at 7pm. All are welcome. We meet in a bar but minors are allowed to attend. We are not in a private room; parental discretion advised. If you are a minor or are responsible for one who's attending, please email the organizer in advance at chapter-DC@toool.us Open invite; bring friends! We are the DC chapter of TOOOL.

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.

RULES of the GAME : 1- **FRIENDLY GAME**. No slide tackling, rough play, or coaching. 2- It is highly recommended to wear **TURF SHOES**. However, if you choose to wear cleat and you step on someone foot, you have to leave the game for **2 MINS OUT** and the time would increases if you do it again during the same game. 3- In case of disagreement during the game, the **host acts as a referee** so the game stays smooth and enjoyable to everyone. **Please do not show up unless you're confirmed** and your name shows in the going list. You might not play if you show up anyway. **If you can not make it , cancel ahead of time** (prior to 10 pm the night before), otherwise, you will not be prioritized for the future games. No-shows without cancellation would make you lose your spot the next game. If your name is on the wait list, I would assume you are still interested to join, if not remove your name from the wait list. **Every player should sub for a goalie and offer to play defense.** Please use a clear profile picture so it is easier for me to recognize you. if you don't have a clear picture, the host might cancel your rsvp. If you plan on playing with us regularly , keep in mind we collect yearly donations of $25. For donations you can zelle me (3189143325) or Venmo(@Aladdin-Alayoubi)

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.

THIS GAME IS BASED ON AN OLD GAME , SO MOST OFTEN YOU WILL NOTICE THAT PEOPLE ( THE FOUNDERS) ARE ADDED BEFORE THE RSVP EVEN OPENS. After that, few spots are available for first reserves and the Host has the right to choose the added people from the wait list (Based on dependability, punctuality and cooperation) ***No wait list show ups*** No-shows will be taken seriously and you lose your privilege to RSVP the next game. This is an early game, so you have to cancel the night before. If you cancel late, it will be considered no show. Please wear turf shoes (no cleats) in this field. Please use a clear profile picture so it is easier for us to know each other. if you don't have a clear picture, the host might cancel your rsvp. If you plan on playing with us , keep in mind we collect yearly donations (Collected once a year ,$25). You can zelle me (3189143325) or Venmo(@Aladdin-Alayoubi) or give cash.

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.

Pay attention! We’re delaying a week for those of you who may be on Spring break and/or celebrating the holiday. Ok, no pancakes, but waffles-a-plenty. Join the local UX and Digital Design community for a casual monthly breakfast. Look for us upstairs!
