One area in which Java has an advantage over typical HPC languages
(C/C++/Fortran) is its ability to use information at runtime to fine tune the
code. If used well, this allows you to write code that is a bit more general without
sacrificing performance, as the code will get "re-specialized" at runtime.
While in C/C++ sometimes you are stuck with macros or preprocessing scripts,...
I have just
made available a zip bundle on the Jabble site in response to
some users that got stuck in the installation process: new to Jabble,
new to NetBeans, new to Java... it's tough!.
The ideal solution would have been WebStart installation - one

that... hopefully they will be in the next NetBeans release...
