Schneier’s Law Applied to Networking
A while ago I stumbled upon Schneier’s law (must-read):
Any person can invent a security system so clever that she or he can't think of how to break it.

Any person can create a clever network design that is so complex that she or he can't figure out how it will fail in production.
I know I’ve been there with my early OSPF network designs.

“Simplicity is a great virtue but it requires hard work to achieve it and education to appreciate it. And to make matters worse: complexity sells better.”
― Edsger W. Dijkstra, which is a pleasing example of cosmic symmetry as his famous algorithm was about computing shortest paths.
