43:43

Wyatt Flores is a 23-year-old singer-songwriter from Stillwater, Oklahoma, who’s making a name for himself in the Red Dirt music scene, building on the musical legacy of his home state. He grew up on a ranch in a working-class family where he was surrounded by musicians, often hearing them play cowboy songs around a campfire. His father, a drummer, built him a stage in the backyard when he recognized his talent, and his Uncle Bobby taught him how to play guitar. Now Wyatt is playing in front of thousands of fans, singing at the Grand Ole Opry, and writing songs that are winning audiences with their honesty, heart, and vulnerability. His debut album, Welcome to the Plains, explores the rough—and sometimes violent—side of growing up in rural Oklahoma, but it also shows a talent for storytelling and a wry sense of humor. Sid talks to Wyatt about why he’s so happy to be back in Stillwater after a couple of years in Nashville, the mental health struggles he’s openly shared with his fans, the family member he wants to have on his podcast, and why his favorite food is a breakfast burrito.

Ever wondered what it's like to be a VP or Director of Engineering? Kendra chats with Alex Robson about leadership in technology, what you can get out of coaching or an MBA program (should you be interested), and what makes a high performing team. We'll also chat about recommended content to hone your tech leadership skills. Alex Robson's site and blog: https://robsonconsulting.services Alex's content recommendations for folks who want to think more about technical leadership: "I believe Camille Fournier and Will Larson are wonderful writers with invaluable insights and advice. For product thinking, I recommend folks read The Lean Startup by Eric Ries, Principles of Lean Product Development Flow by Don Reinertsen, Safer Sooner Happier by Jonathan Smart, and Accelerate by Dr. Nicole Forsgren. Be sure to read books on leadership that are outside of engineering. Dan Pink’s Drive and Eliyahu Goldratt’s The Goal are two of my usual recommendations. Last but not least - read books that are about human behavior. Both economists and psychologists ask important questions that may help you unlock better ways to relate to and understand others. I love Daniel Kahneman’s Thinking Fast and Slow, and highly recommend Mistakes Were Made (but not by me) by Carol Tavins and Elliot Aronson."…

One small localization correction: the default collation on a SQL Server install will be "the oldest available version that's associated with each specific locale." So if your Windows installation has a different localization than mine (which are generally English USA), then you'll see a different default collation -- but it still won't be the recommended collation for *new* development.…
