We meet to learn and practice American Sign Language and to grow our familiarity with Deaf culture. Facilitated by hearing folks (with a connection to a professional interpreter) using Deaf-created content. People of all ASL skill levels are welcome! As we learn, we hope to connect more with the Deaf community in Central Ohio. Join us as you're able! Come regularly or just once - whatever you're looking for! Each meetup will explore different topics related to ASL/Deaf culture, and will feature time to practice conversation with one another. Just bring yourself and a willingness to learn!

Greetings writers! Come down and join your fellow wordsmiths for one hour of uninterrupted writing time in the upper level of the Market District Supermarket in Upper Arlington. The main entrance of the shopping center opens onto stairs/elevator leading up to the 2nd floor cafe section where we will have a table displaying a sign with the Shut Up & Write logo. Writing is largely a solitary craft. Practicing with others in a community setting may be the thing you need to fire your own routine. We’ll meet on Wednesday evenings, starting the clock at 6:30, following a brief period of introductions. This is solid writing time and all inclusive. Any project is acceptable, be it fiction, non -fiction, work or homework assignment. All is welcome and will remain private to you. The market boasts a Starbucks, a full service bar and various affordable food options. Parking is plentiful, free Wifi is provided as well as outlets for charging your devices, though they are somewhat limited, so plan accordingly. Show up as early as you like, or stay late. This group tends to socialize some, both before and after the alloted time, but this is not mandatory to you. Feel free to come and go as you please and late arrivals are welcome. The cafe may be noisy on occasion so headphones/ earbuds are reccommended as you see fit. Please try to RSVP if possible so that we may grab enough seats for all—the venue can be busy at times. Feel free to message me privately wth any questions and/ or concerns you may have. Happy writing!

Highlights and Hidden Gems in SQL Server 2025 With so much emphasis on cloud data platforms and AI these days, SQL people can feel left behind by all the marketing hype. SQL Server 2025 was officially released in November of 2025, though, and contains a ton of improvements that will make our SQL Server deployments a bit faster, better, and more secure. There are even more improvements tucked into the release that never made a marketing blog or press release that you'll likely be learning about for the first time in this session! Join this session to learn about what makes your high availability a little more available, your performance a bit more performant, and your database more developer and app-friendly. Come spend an hour with SQL people talking SQL Server 2025 – the good, the "not quite ready for prime time", and the hidden awesomeness.
