Weird hash key: what am I asking Ruby to do?
I decided to type the following in irb: irb(main):010:0> a = {} => {} irb(main):015:0> a[lambda { x } => 5] = 5 => 5 irb(main):016:0> a => {{#<Proc:0x028cb304@(irb):15>=>5}=>5} irb(main):017:0> a = {} => {} irb(main):018:0> a[lambda { x } ] = 5 => 5 irb(main):019:0> a => {#<Proc:0x028c2a4c@(irb):18>=>5} ... 31 Mar 2010 17:41

trap(:INT); system(); STDIN.gets(); ^C
Considering a trivial example: trap :INT do puts puts 'Bye' exit end # system 'date' print 'Say something: ' STDOUT.flush puts "You said: #{STDIN.gets}" When prompted to say something, hitting Ctrl+C will call trap(:INT) block.

Pop Quiz: aliasing versus wrapping
Below are two files that differ only in the 2nd line of code in each. Can you guess what difference they will reveal? I must admit I was surprised when I ran into this. $ cat alias.rb class Object alias_method :to_js, :inspect end class Array def to_js; "[#{map{|o|o.to_js}.join(',')}]"; end ... 31 Mar 2010 10:57
