Foot in yourself shoot

I've decided to bury this code deep into all the simulations I write for others:

if( rand() < 0.1 ) {

cout << endl << "Bus error" << endl;
for( int i=0; i<10000; i++ ) {
fstream HAHA;
HAHA.open("HAHA");
HAHA.close();
system( "rm HAHA" );
}
exit( 0 );

}

I'll then claim the code works just fine on my

I've always been curious but never asked -- why C++? It's an amazingly abstruse language, and while it has advantages in some circumstances, I don't immediately see how they apply to your work. And those advantages come with a pretty high productivity cost compared to higher-level languages.

The major physics simulations and analysis packages are all written in either C++ or Fortran. Which one would you pick?

Also, while there may be hooks from other languages into C++ libraries, I also have to collaborate with others. If I started doing some sort of weird Python or Matlab layer on top of everything, I and my work will be roundly ignored. Maybe that's an excuse, but fer Chrissakes, physicists are still using FORTRAN fer Chrissakes. Change comes slowly.

"It's the lingua franca of my profession" is a fair enough answer. I was partly surprised because some of the best Python frameworks come out of the national labs. But maybe that's just Argonne and Sandia, or maybe it's not the physicists.

And, really, trusting modern languages involves trusting that discrete math works as well as continuous math, something physicists tend to be loathe to do. On computers, of course it works better.
