This post pairs nicely with Julia Evans’ post on why most people use the Linux kernel’s TCP/IP stack and why a few others would bother with a userland stack. In her post she doesn’t mention fly.io’s motivation for doing userland TCP-IP: a nicer end user client experience. If I read this correctly then fly.io did all this work to make their CLI user experience markedly better. That’s pretty cool. Twist yourself in interesting knots to make your user’s lives better, maybe even in ways they won’t notice!
