Kenwood, a Chevy Chase neighborhood near Bethesda, has 1,200 cherry trees lining its streets, along with bevies of glorious gardens in this upscale area.

Let's see Project Hail Mary, the new scifi Ryan Gosling. I heard the trailer majorly spoils the book which I'm frantically trying to finish it off before the movie in a week. Same directors as the Jonah Hill/Channing Tatum 21/22 Jump Street movies, so it could be fun. I'll be in seat H8. We'll get food afterwards.

Just good ole Ultimate Frisbee. Tons of fun. Great group. No stacks. No pick calls (but no picks!!!). Fair warning to those totally new to ultimate: it's a lot of running. \*\*Please pay close attention to the rule #6 listed below. *What to DEFINITELY bring* 1. Running shoes/Cleats 2. One white shirt *and* one dark shirt !!!! See this one !!!! \-\-\- IMPORTANT you can play both dark and white so we can make teams when we get there; just pickup after all 😎 3. Water *What you can ALSO bring* 4\. Snacks & Drinks 5\. Gloves \(winter\) 6\. Sunscreen \(summer\) 7\. Sunglasses 😎 House Rules - 1. Starting Play: Each point begins with both teams lining up on the front of opposite end zone lines. The defense throws ("pulls") the disc to the offense. 2. Scoring: Each time the offense catches a pass in the defense's end zone, the offense scores a point. The teams switch direction after every goal, and the next point begins with a new pull by the team that just scored. 3. Movement of the Disc: The disc may be advanced in any direction by completing a pass to a teammate. Players may not run with the disc. The person with the disc ("thrower") has ten seconds to throw the disc. The defender guarding the thrower ("marker") counts out the stall count. 4. Change of Possession: When a pass is not completed (e.g. out of bounds, drop, block, interception, stalled), the defense immediately takes possession of the disc and becomes the offense. 5. Substitutions: Players not in the game may replace players in the game after a score and during an injury timeout. (Modified depending on the number of the attendees) 6. Non-contact: Players must attempt to avoid physical contact during play. Picks and screens are also prohibited. 7. Fouls: When a player initiates contact that affects the play, a foul occurs. When a foul causes a player to lose possession, the play resumes as if the possession was retained. If the player that the foul was called against disagrees with the foul call, the play is redone. 8. Self-Officiating: Players are responsible for their own foul and line calls. The host will also step in if it is needed. Please message the event host for any questions or concerns. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **Smiley Social documents:** 1.

Let's bedazzle some books while we discuss our April pick: Bloodguard by Cecy Robson! Book description: One hundred years. Tens of thousands of gladiators. And today, only one will rise… Everything in the Kingdom of Arrow is a lie. Leith of Grey thought coming to this new land and volunteering to fight in the gladiator arena—vicious, bloodthirsty tournaments where only the strongest survive—would earn him enough gold to save his dying sister. He thought there was nothing left to lose. He was wrong—and they took everything. His hope. His freedom. His very humanity. All Leith has left is his battle-scarred body, fueled by rage and hardened from years of fighting for the right to live another day. Then Leith meets Maeve, an elven royal who is everything he despises. Everything he should hate. Until the alluring princess offers him the one thing he needs most: a chance to win the coveted title of Bloodguard—and his freedom. But in a kingdom built on secrets and lies, hope doesn’t come cheap. Nor will his ultimate revenge… Event: Please bring your own book, journal, bookmarks, etc to bedazzle. If you have bedazzling supplies, please bring them as well. I will supply gems, glue, and picker tools, but if you have certain colors in mind, you may want to bring your own.

The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively. This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way. **YouTube Link** TBA
