Programming-vs-networking Memes

Network engineers picking up programming? Fun times—they already know the stack, just add some semicolons and call it a day. But programmers trying to learn networking? Welcome to hell. Suddenly you're drowning in subnets, CIDR notation, NAT tables, and DNS propagation delays that make you question your career choices. The title says it all: everything works beautifully on localhost (127.0.0.1), your app is a masterpiece, tests pass, life is good. Then you try to deploy it to an actual network and suddenly you're troubleshooting why your service can't reach the database, why CORS is blocking everything, why your firewall rules hate you, and why "it works on my machine" becomes your most-used phrase. Fun fact: Network engineers have been dealing with Layer 2 vs Layer 3 drama while you were still figuring out if arrays start at 0 or 1. Respect the craft.
