In celebration of Whyday: Rubyists always want to show others the beautiful code 
they have created, hence the question: Has Anybody Seen My Code?

Has Anybody Seen My Code
(sung to the tune of Has Anybody Seen My Gal)

Clean and small, works for all,
Ruby is my all in all.
Has anybody seen my code?

# After reading this comment

#
# I became aware of a cool idiom for Ruby.
#
# I've seen this in a lot of cases:

if (variable = expression_or_method(options))
  variable.calculate_something
  do_other_stuff(variable)

# 30 minutes Lisp in Ruby
# Hong Minhee <http://dahlia.kr/>
#
# This Lisp implementation does not provide a s-expression reader.
# Instead, it uses Ruby syntax like following code:
#
#     [:def, :factorial,
#       [:lambda, [:n],
#         [:if, [:"=", :n, 1],
#               1,

Fibur

Fibur is a library that allows concurrency during Ruby I/O operations without needing to make use of callback systems. Traditionally in Ruby, to achieve concurrency during blocking I/O operations, programmers would make use of Fibers and callbacks. Fibur eliminates the need for wrapping your I/O calls with Fibers and a callback. It allows you to write your blocking I/O calls the way you normally would, and still have concurrent execution during those I/O calls.

Example

Say you have a method that fetches data from a network resource:
