    Project mention: What led you to use Linux as your daily driver? | /r/linuxquestions | 2023-12-07

    I started with Linux in the late 90s. I switched to FreeBSD around 2013 and returned to Linux a couple of years ago. Io_uring was the main reason I had to come back. At first I ported the back tier of my code generator back to Linux and then I ported the middle tier from being POSIX based to Linux.
