Its melodious …its amazing and i can keep humming one or other track all the time. Really i loved it 🙂

Chris has the music for Ruby/Rails Community.He calls is IRB Mix .Tape and its just fantastic.

Track 4 about sandboxing is just mind blowing…

$ ruby script/console --sandbox
Loading development environment in sandbox.
Any modifications you make will be rolled back on exit.

And Track 5 about underscore operator (_) .I hadnt found yet anything in irb giving the value of last evaluated expression in Ruby. But ‘_’ does this cake thing for me. Good job Chris 😀

One more small thing that i learned from one of the comment….

>> 4*4
=> 16
>> 4**4
=> 256
>> 100**100**100
c:/ruby/lib/ruby/1.8/rational.rb:543: warning: in a**b, b may be too big
