So, if we add it all up, then GNU/Linux and Windows are - at least, from
the purely technical point of view; I won't be discussing licensing
etc. - both descendents of UNIX, with GNU/Linux having the most UNIX
DNA and Windows being an offspring of an offspring of an offspring that
had serious genetic flaws. :p
Aragorn, modern Windows made a quantum shift from UNIX to VMS with the
release of NT, brought in by David Cutler and his work from DEC. NT
and its VMS roots remains at the core of all contemporary Windows
releases. Memory management, particularly, inherited a lot from
David's works.
Well, I don't see Windows running natively - as in "on the bare metal" -
on an IBM S/390 yet. ;-) GNU/Linux on the other hand is quite capable
of that, albeit that it's typically far more practical to run it inside
a virtual machine, even if only because of the limitations of the
amount of logical (processor) partitions in the Linux kernel versus
OS/390 (which I think is now called differently - zOS or something of
the likes? - but anyway).
Heh. The advantage of having a publicly available toolchain for
building your compilers (gcc), your core libraries (glibc), and your
kernel (Linux) combine to make Linux wildly portable to multiple
architectures. The fact that those toolchains actually follow the
standards rather than internalizing and hiding nasty hacks behind
"licensing agreements" only helps migration.
