**Caller: Frank Buschelmann** **Band: The Rosenthorns** **Big Scioty Contra Dance** **temporarily returning to our long ago location for Jan-March - First Congregational Church, 444 E. Broad St., Columbus 43215** WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing! Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor. Be sure to come for the beginner's lesson from 7:30 - 8:00, followed by dancing 8:00 - 10:30. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner. Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot. For more information contact me or check out our website: [www.bigscioty.com](http://www.bigscioty.com/) Please bring your own refillable water bottle. Snacks to share are always welcome!

This, her mother has told her, is the only way to get a "louding voice" -- the ability to speak for herself and decide her own future. But instead, Adunni's father sells her to be the third wife of a local man who is eager for her to bear him a son and heir. When Adunni runs away to the city, hoping to make a better life, she finds that the only other option before her is servitude to a wealthy family. As a yielding daughter, a subservient wife, and a powerless slave, Adunni is told, by words and deeds, that she is nothing. But while misfortunes might muffle her voice for a time, they cannot mute it. And when she realizes that she must stand up not only for herself, but for other girls, for the ones who came before her and were lost, and for the next girls, who will inevitably follow, she finds the resolve to speak, however she can--in a whisper, in song, in broken English--until she is heard

One of the most valuable parts of this community is the opportunity to think out loud with other product professionals. This session is built for exactly that. As we wrap up the quarter, it’s a great time to pause and reflect. What’s on track? What needs adjustment? Where could a small shift create bigger impact? Join fellow product professionals for a focused, interactive conversation designed to help you recalibrate for the next quarter. You’ll have the opportunity to share where you are, hear how others are thinking through similar challenges, and gain fresh perspective you can bring back to your team and organization. We’ll gather at 8:00AM, with discussion starting promptly at 8:15AM. 📍 First Watch - 7227 N High St Located in: The Shops at Worthington Ample parking is available. Food and beverages will be available for purchase. Start your morning with clarity and connection — we hope to see you there! ☀️

## Hey Columbus WIP peeps! ## Are you ready for an event that actually gives you what you asked for?? **\-\-\-\-\-\-** **A Small-group coaching conversations for women in product navigating growth, leadership, and career decisions.** **March 10 \| 5:30–8:00 PM** **Rev1 -- NEW SPACE** **330 Rush Alley #100** **Parking Options:** • **Rev1 at The Peninsula** • **Starling St. Garage South** – 377 W. Capital St. • **LAZ Parking (COSI)** – 50 Belle St. • **LAZ Parking Limited** – 375 W. State St. • **Veterans Memorial Lot** – 300 W. Broad St. • **Metered Street Parking** **What moves are you making?** A promotion you’re working toward. A role change you’re considering. A bigger leadership opportunity. A conversation that needs to happen. A decision that’s been sitting in the back of your mind. For our Q1 Women in Product Columbus event, we’re creating space to actually work through those moments. **Making Moves** is an evening of focused, facilitated coaching conversations with experienced mentors from our local product community. This isn’t a panel. It’s not passive networking. It’s small-group dialogue designed to be thoughtful, practical, and worth your time. Here’s how it will work: • You’ll choose a topic that reflects what you’re navigating right now • You’ll join a small coaching circle (5–7 participants) • Each circle is led by a mentor who has lived experience in that area • We’ll run two rounds so you can go deeper or explore a second conversation ### Coaching Topics: • Communicating the Value of Your Work (or Team) • Career Transitions & What’s Next • Growing Into Leadership • Staying Relevant as Technology (and AI) Changes • Getting Alignment and Decisions from Leadership Our goal is simple: you leave with clearer thinking, practical perspective, and at least one next step you feel confident about. Space in each circle will be limited to keep conversations meaningful. If this sounds like the kind of room you’ve been wanting to be in, we’d love to see you on March 10. RSVP here!

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!

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.
