I'll actually change "smartass" to "dumbass" if you are unable to find a source on the internet that SPARC in a native big-endian architecture.
Changing the subject, are we?
Solaris is actually a pair of quite distinct OS-es: the classic big-endian SPARC one and the newfangled little-endian on x86/x64. They have significantly different security profiles.
You've claimed that Solaris was much safer and that the graph was false. One last try?
