Have stdout/err output you just can't track down? Use this. It needs to be inserted in the earliest possible load path (like spec_helper or rails boot.rb)
def STDOUT.puts *args
super(*args)
STDERR.puts(caller[0..5]) if args.any?{|a| a.to_s =~ /my semi-unique string/ }
end

localshred / binary_search.rb
Created February 28, 2012 07:22
Land of Lisp binary search algorithm in ruby. This is in stark contrast to my verbose approach in the summer of 2011: http://rand9.com/blog/picking-the-right-number-as-quickly-as-possible/
# set some vars
@high = 100
@low = 0
# Simply calc the midpoint (no remainder)
# of the high and low value (bit shift right)
def ask
(@high + @low) >> 1
end

localshred / 1.9.2_ex.irb
Created March 6, 2012 23:57
1.9.3 changes the behavior of "rescue else" in a method from previous ruby versions. A return in the method body will not trigger the else.

localshred / symbolized_hash_keys.rb
Created August 9, 2012 17:56
Symbolize keys doesn't do what I expected when to_sym equivalent keys exist.
# Fascinating behavior of symbolize_keys usage. If you have two keys that
# are `to_sym` equivalents, the non-symbol version is the winner,
# regardless of the order in the hash.
# For some reason I expected if a symbol key existed it would be
# the winner.

=> {:one=>1}
1.9.2p290 :001 > {:one => 1, "one" => 2}.symbolize_keys

Reject commits if updating non-dev branch and the Gemfile was changed and contains a list of rejectable words (e.g. git, tag, branch, path, etc.)
