If you feel like me and don’t like the new naming convention when duplicating a symbol in the library of Adobe Flash CS5 maybe here’s a solution.
Some Ruby Idioms
A post as a note to myself to remember some Ruby Idioms ..
# $ruby 1.9.2
#
# Add a value to an array unless its not
# contained already and even it's contained
# multiple times reduce it to a single occurence.
foo = ['bar', 'baz', 'baz'] # => ["bar", "baz", "baz"]
foo |= ['baz'] # => ["bar", "baz"]
# Parallel assignment by "un-splatting" an result array
# Instead of:
match = "Ruby 1.9.2 is awesome".match(/Ruby (d.+) is awesome/)
catch = match[1]
# Use:
catch, match = *"Ruby 1.9.2 is awesome".match(/Ruby (d.+) is awesome/)
# catch => "Ruby 1.9.2 is awesome"
# match => "1.9.2"

Keep your ~/.bash_history entries unique
When often using the terminal you don’t want to type certain commands over and over again. Although recent commands are stored in the .bash_history
in your home-directory they will be overwritten at some point when a new terminal is opened. So you won’t be able to use Ctrl + R
to search for commands you’ve typed longer time ago.
Luckily there is an option to append the terminal commands instead of overwriting them.
