I'm curious as to how programs actually get ported from one OS to
another, and if certain directions are easier than others. That is, how
does one figure out what needs to be changed in order to make OpenNTPD
work on Linux? Is it generally easier to move a program from $some_bsd
to $some_other_os, or from $some_other_os to $some_bsd? How would you
even begin to port something like OpenSSH to a non-Unix system like
Windows? Does the chosen language (C, C++, Java, etc) make a difference
in difficulty? When I've built from ports, I can see make files doing
OS detection, but from there (not being a very good coder), I can't
really make out how it changes the code based on that. Any
recommendations for "casual programmer" books would be cool... I'm not
interested in becoming a kernel hacker or driver programmer, but at
least being able to understand what's going on would be nice.
Not exactly a shallow subject. Take a look at this:

Looks like a great start, but it's marked as being out of print :(
Still, Amazon has to be good for something :) From the description, it
looks like it deals with the first part of my question (the 'how' part),
but I can't tell if it goes into the 'directions' or 'languages' part.
Suggestions there?
