Ten particularly good heuristics for good code (from Clean Code).

E1. Build Requires More Than One Step
E2. Tests Require More Than One Step
G5. Duplication
G10. Vertical Separation
G21. Understand the Algorithm
N1. Choose Descriptive Names
T1. Insufficient Tests
T3. Don't Skip Trivial Tests

I have observed a bug in PATH on 'rvm use' where an extra ' :' is added,
preventing discovery of executables along that last path. Without the debug
info the relevant commmands and output are:

  % echo $PATH
  /Users/Simon/.rvm/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/local/git/bin:/usr/local/instantclient-10.2
  % rvm use 1.8.6@chiangs --create
  Using /Users/Simon/.rvm/gems/ruby-1.8.6-p399 with gemset chiangs
  % echo $PATH
  /Users/Simon/.rvm/gems/ruby-1.8.6-p399@chiangs/bin:/Users/Simon/.rvm/gems/ruby-1.8.6-p399@global/bin:/Users/Simon/.rvm/rubies/ruby-1.8.6-p399/bin:/Users/Simon/.rvm/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/local/git/bin:/usr/local/instantclient-10.2 :

The configuration order - Rails 2.3.3.

   1. config/preinitializer.rb
   2. config/environment.rb
   3. config/environments/#{RAILS_ENV}.rb
   4. plugin initialization
   5. gem initialization
   6. config/initializer/*.rb
   7. all after_initialize blocks, in the order they were defined in (so same order as above)
   8. any junk left below the Rails::Initializer.run call/block in environment.rb

# Two ENV variables control the 'gem' command:
#
#   GEM_HOME: the single path to a gem dir where gems are installed
#   GEM_PATH: a standard PATH to gem dirs where gems are found
#
# A gem directory is a directory that holds gems.  The 'gem' command will lay
# out and utilize the following structure:
#  
#   bin               # installed bin scripts
#   cache             # .gem files  ex: cache/gem_name.gem
