“Code names make sense if you want to keep what you’re doing a
secret. If you’re planning a military operation, you probably don’t
want anyone to know until you actually hit the beaches of France.
Or maybe in the case of the revised Doctor Who, when you’re a
producer who doesn’t want the excitement to peak too soon (in which
case, you pass around sheets of paper watermarked with “Not to be
copied” and call what you’re doing “Torchwood,” then decide the
name would make a great spinoff series).
But in this community? What part of “free and open source
software” don’t you understand?
