This is a short followup to my last post where I compared library RubyForge statistics against CPAN. This week I compare RubyForge against…the Ruby Application Archive! Yes, I know, the RAA is just a listing service and RubyForge is not. That’s not the point. Please read on. In the last post I… read moreSeptember 26 2007
It’s often been said that Perl’s greatest strength is CPAN, Perl’s vast collection of free libraries contributed by developers from around the world. Recently I started to wonder about RubyForge and how RubyForge stacks up against CPAN in general.1 First, length of service. CPAN has been around for 12 years (October… read moreSeptember 19 2007
