DavidEGrayson / boolean_with_reason_ugly_example.rb
Created October 20, 2011 05:55
Wouldn't it be cool if we could make a BooleanWithReason Class in ruby
ugly_hair = false
ugly_nose = true.because "the nose is too small."
ugly_glasses = false
ugly_face = ugly_hair.or(ugly_nose).or(ugly_glasses)
if ugly_face.true?
puts "The face is ugly because " + ugly_face.reason # => "The face is ugly because the nose is too small."
end

`rvm rvmrc load` fails first time but succeeds subsequently
Reported on IRC and at: https://github.com/wayneeseguin/rvm/issues/1268
I think I have found a bug with RVM. Here is what happens:
david@rails-worker1:~$ sudo su - website
[sudo] password for david:
website@rails-worker1:~$ cd /u/apps/website/current
website@rails-worker1:/u/apps/website/current$ env > ~/env0.txt
website@rails-worker1:/u/apps/website/current$ rvm rvmrc load
Usage: rvm rvmrc {trust,untrust,trusted,load,reset,is_trusted,try_to_read_ruby,create}
