Servers for Hackers is the long-running technical-publication and course site of Chris Fidao, focused on the production-operations side of running PHP and Laravel applications — the parts of shipping software that don't fit inside a framework tutorial. He also runs Fly.io for Laravel and Chipper CI, and has been one of the most consistent voices on the Laravel deployment / DevOps boundary.
The CourseFlix listing carries Scaling Laravel and Deploy PHP! — both paid courses aimed at PHP developers ready to take operational responsibility for their own services rather than handing them off to a separate ops team.
