Hi, all, I am anxious to know empirical comparion of Ruby and other languages for several properties, such as run time, memory consumption, source text length, comment density, program structure, reliability, and the amount of effort required for writing them. Is there any comparison data other than http://www.bagley.org/~doug/shootout/craps.shtml ? Refer to following papers An empirical comparison of C, C++, Java, Perl, Python, Rexx, and Tcl. (http://wwwipd.ira.uka.de/~prechelt/Biblio/jccpprt_computer2000.pdf) An empirical comparison of C, C++, Java, Perl, Python, Rexx, and Tcl for a search/string-processing program(http://wwwipd.ira.uka.de/~prechelt/Biblio/jccpprtTR.pdf) Hee-Sob Park
