No, really. The author, whose name I can't remember at the moment, complains that X has the server/client roles reversed; that xcalc is a server and the display is a client. The usual defense is that it's "tongue in cheek", but from a networking standpoint it is simply wrong.

You login to the server and run application, that application connects to the X Server on your client.

| Client +---->+ Server |

| |X Server +<---------+Application| |

I can see how confusion may arise.
I have. It was written by someone who doesn't know the difference between a "client" and a "server".
