Both ideone.com and codepad.org have Little-Endian architechtures.
I want to test my code on some machine with Big-Endian architechture (for example - Solaris - which I don't have). Is there some easy way that you know about?
Googling "big endian online emulator" lead me to PearPC. I assume that if you have the patience you can install Mandrake Linux, get gcc, and go party.
