A number of the specifications for how things work on the Internet begin life as an RFC, or Request For Comment. For example, RFC 2616 lays out the basis for the HyperText Transfer Protocol or HTTP which controls how a web browser downloads pages from a web server. (That’s what that “http://” is for at the beginning of all web page addresses.)
Today I became aware of RFC 1925 which discusses “fundamental truths of networking for the Internet community.”
My favorite part is section 2.3 which reads:
With sufficient thrust, pigs fly just fine. However, this is not necessarily a good idea. It is hard to be sure where they are going to land, and it could be dangerous sitting under them as they fly overhead.
