There's actually a lot: programming by contract, for example, or
intelligent management of locks. Or distribute a program for
which you can give reasonable guarantees of reliability on any
platform on which it runs (i.e. no dynamic linking).
I work mainly on large servers. I can't use Java for
reliability reasons; my code must work, every time.

GUI is easier in Java. I've had no problem networking in C++,
and all of the large servers I'm familiar with (e.g. Apache,
etc.) are written in either C or C++---never in Java. When I
wrote the server for dynamic allocation of IP addresses
(networking), we used C++ for the server itself (for reliability
reasons, mainly---we guaranteed up time), and Java for all of
the interface code around it (mostly beans under WebSphere).

And if the code is only supposed to run on one machine, or a
small set of machines? With care, it's possible to write C++
code which ****ts easily to most Unix machines, and for large
scale servers, that's all you're interested in anyway.
