OK, I might've chosen violence when I submitted "Why I ❤️ C#" for @nljug.bsky.social's annual #JFall conference. But it's the program committee that accepted it, really!
/JK, I know you have a difficult job each year and I appreciate your efforts. Looking forward to present both sessions this fall!
