Standard practices say no non-root process gets to talk to the Internet on a port less than 1024. How, then, could I get Node talking on port 80 on EC2? (I wanted it to go as fast as possible and use the smallest possible share of my teeny tiny little micro-instance's resources, so proxying through nginx or Apache seemed suboptimal.)
Alter the port the script talks to from 8000 to 80:
}).listen(80);

When hosting our web applications, we often have one public IP
address (i.e., an IP address visible to the outside world)
using which we want to host multiple web apps. For example, one
may wants to host three different web apps respectively for
example1.com, example2.com, and example1.com/images on
the same machine using a single IP address.
How can we do that? Well, the good news is Internet browsers
There are three easy to make mistakes in go. I present them here in the way they are often found in the wild, not in the way that is easiest to understand.
All three of these mistakes have been made in Kubernetes code, getting past code review at least once each that I know of.
What do these lines do? Make predictions and then scroll down.
