I'm giving a presentation to my research group next month about Ruby
(mainly an intro), but seeing as though it's in a Computer Science
department, with plenty of people who have several decades of
programming experience in many different languages, I'm trying to come
up with some examples of (among other things) how Ruby's dynamism can
be taken to extremes. My first thought was satisfying Orwell's famous
"Nineteen Eighty Four" proposition about mathematical adherence to Big
Brother:
class Fixnum
alias old_plus +
def +(arg)
if self == 2 and arg == 2
5 # INGSOC compliance
else
old_plus(arg)
end
end
end
Any improvements, or other neat little examples I can use? I've also
adapted the VCR-proxy example (pimple-class using method_missing to
catch, record and pass on method calls).
Many solutions to the latest ruby quiz used breadth-first search, a classic computer science algorithm. There were a wide variety of solutions, filled with neat examples of ruby-isms. I'm sure you can find some gems for your presentation by looking here:

I always like the interchangeability of lambda# and Hash# which allows
for poor man's memoize:
fun = lambda {|x| x + 10 - 2}
code = optimize ? Hash.new {|h,k| h[k] = fun[k]} : fun
1000.times { code[100] }

Well, I don't know how much they'll impress such old salts, but you can find examples of my wide-eyed wonderment in my Nuby files:
