<html><div style='background-color:'><DIV>I have used Ruby and some others (Perl, Python, etc.) for some useful things. Those who know these languages, don't need to say why. But when it comes to the ultimate application like a language itself (Ruby, Perl, Python, etc.), nothing can beat the awesome C. To my knowledge, most advanced chess programs (Deep Blue, Fritz, Junior, Shredder, etc.) are written in either C or C++, never Prolog or Lisp. Mastering C/C++ is still required when it comes to performance. If a chess program in Ruby can beat all those chess programs in C/C++, no naive propaganda for Ruby needs to be made. So far I haven't spotted any Job that requires Ruby, but the trio C++/Java/C#; most companies and managers are very well informed.</DIV></div><br clear=all><hr>STOP MORE SPAM with the new MSN 8 and get 2 months FREE*</html>
