I disagree.  If you look at struct sockaddr_t used by bind(2) and
friends, you will see that the address and port number are in network
byte order; you need to understand how, when and why to swap bytes.
Just saying.

Besides, just because, by some made-up statistic, the majority of
programmers use a high-level framework to write disposable web
applications does not mean I want to be part of that majority, or that
I want my programs to be disposable, or that I want to hire
programmers who can't extract a bit from a byte.
