The last time I tried NetBeans, it was a pure Java IDE.
I run Eclipse at work for C/C++ development.

yes, but QtConcurrent is more like a scheduler. QtConcurrent::run internally re-uses threads
and runs your given functor object.

I was thinking about something like QThread(Functor), without the need to subclass
QThread and implement a run Method (I'm aware about the exec() call in QThread::run).

boost::thread has a different design concept than QThread. I would appreciate if Qt
would introduce a Functor-style API for Threads.

boost::signals doesn't work across threads (this is docuemented in the boost API).

Throwing both Qt and boost APIs together would create an ugly mess.

The EFF, FSF and ACLU are some kind of lobby organizations.

Feet, miles and knot based units are the de facto standard in aerospace. The scientists
use SI units, the pilots do not. For a software I wrote I had to use SI units internally
and had to convert those values to feet/miles/knot based ones before passing them into a
pilot specific software. I work in germany (at the DLR if it matters).

This is a classic problem with most *nix distribution packages and CPAN usage. This is not Apple specific.
