OneAndOneIs2

So I got this email telling me that, in honor of Valentine's Day, O'Reilly are doing a special sale on all their pink books.

This prompted me to wonder what the logic was behind their colour-coding. Most of their books that I have to hand are blue. But a few are pink. Others are red.

Looking at the list, I couldn't see an obvious answer: There were books about using vim, emacs, git etc. so I wondered if it was "guides to using software" but then there's books on Python and Erlang and C, so that ruled that out.. But it couldn't be "pink for programming" because the Perl book is blue...

So I tracked down the answer, and was highly amused by it: Apparently, pink does mean "Programming". Blue means "Perl"

So, judging by their colour-coding, as far as O'Reilly's concerned, there's Perl, and there's Java, and then there's everybody else.

I like it :)
