**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!

Columbus libraries: [https://cml.bibliocommons.com/v2/record/S105C3262835](https://cml.bibliocommons.com/v2/record/S105C3262835) Location: [Knotty Pine Brewing](https://www.knottypinebrewing.net/) [Menu, scroll to the bottom](https://www.knottypinebrewing.net/menus-1) Book summary: Adunni is a fourteen-year-old Nigerian girl who knows what she wants: an education. 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

I'm talking about Nullable Reference Types. In this presentation, I we dig into this feature, explore why it exists, what problem it tries to solve, how it works, and how people have critiqued it, so that you as a programmer can decide if and how you want to use it.

Our monthly PHP meetup. A virtual shindig courtesy of Zoom. Check back here for the details around 6:15 pm

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.

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!
