Repeat for any other testing lib for even more speedup

1 Activate DRB in Rubymine
Run > Edit configurations > Defaults > RSpec > Use DRB Server

2 a) Start spork from Rubymine
Tools > Run Spork DRB Server

2 b) (alternatively) start spork from the commandline
Code

  # spec/spec_helper.rb
Spork.prefork do
  if ENV["RUBYMINE_HOME"]
    puts "Rubymine support"
    $:.unshift(File.expand_path("rb/testing/patch/common", ENV["RUBYMINE_HOME"]))
    $:.unshift(File.expand_path("rb/testing/patch/bdd", ENV["RUBYMINE_HOME"]))
  end
end

and run it via:

RUBYMINE_HOME=/Applications/Rubymine\ 3.2.4.app/ spork

Behold the perfect current_path_info, which returns the full path and query + fragment.

Code

def current_path_info
  current_url.sub(%r{.*?://},'')[%r{[/\?\#].*}] || '/'
end

Creates a new travis hook based on the travis info in your .gitconfig
and also triggers the initial test-run.

add to ~/.gitconfig

[travis]
  user = xxx
  token = yyy

download & run the Script
wget https://raw.github.com/grosser/dotfiles/master/bin/github-add-travis

./github-add-travis github-password project-name

After reading some articles I realized that public domain does not always work since some countries do not allow it and its also unclear what happens when the code causes problems <-> lawsuit.

Ill also try to add a s.license = ‘MIT’ to all gemspecs, to make license management easier.

1. Choose a short name for your computer, it will later show in the prompt. Only enter your firstname/alias, it will always show in the toolbar.
2. Enable canonical partners in “Software Sources” > Other Software
3. Install RBEnv

   sudo apt-get install curl zlib1g-dev libssl-dev libreadline6-dev libncursesw5-de libxml2 libxml2-dev libxslt1-dev libsqlite3-dev -y
   cd
   git clone git://github.com/sstephenson/rbenv.git .rbenv
   echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
   echo 'eval "$(rbenv init -)"' >> ~/.bashrc
   git clone git://github.com/sstephenson/ruby-build.git
   cd ruby-build
   sudo ./install.sh
   rbenv install # choose which rubies you want (atm ree is broken...)
   
   # rbenvsudo
   function rbenvsudo(){
     executable=$1
     shift 1
     sudo $(rbenv which $executable) $*
   }
   

4. Rubymine to /opt/rubymine

   Command key:
   Choose “meta is mapped to left win” in advanced keyboard layout options

   Executable:
   /opt/rubymine/bin/rubymine.sh and setup mine as executable then

   alias m="mine . > /dev/null 2>&1 &"
   

   Fix multi-clipboard issues:

   echo 'idea.use.alt.clipboard.sync=true' >> /opt/rubymine/bin/idea.properties
   

   Sun-java: It is no longer in ubuntu repos.

   sudo add-apt-repository ppa:ferramroberto/java
   sudo apt-get update
   sudo apt-get install sun-java6-jre
   export RUBYMINE_JDK="/usr/lib/jvm/java-6-sun/jre"
   

5. Map unity menu from super to Super+z, so you can use it with shortcuts (see below) and with rubymine commands
   sudo apt-get install compizconfig-settings-manager -y
   open compiz application and rebind unity laucher @ “ubuntu unity plugin”, dont mess with anything else, I managed to make ubuntu no longer boot into a GUI with just a few clicks
6. Shortcuts
   Super+D = desktop
   Super+E = open home
   Super+Up = maximize
   Super+Down = minimize
   Super+Q = quit application (Alt+F4)

7. Chrome sudo apt-get install chromium-browser -y
8. Git sudo apt-get install git-core
9. Ruco commandline editor gem install ruco
10. copy important dotfiles + firefox history/forms/… database from .mozilla
11. dotfiles
12. Multi-clipboard sudo apt-get install clipit
    (set history shortcut: Ctrl+Alt+V)
13. Skype + add skype to startup
    (video fix in dotfiles –> add add /home/xxxx/dotfiles/bin/video-skype to “Startup Spplications” )
14. Mysql:
    sudo apt-get install mysql-server mysql-client libmysql-ruby libmysqlclient-dev -y
    I`d recommend no root password
15. Redis sudo apt-get install redis-server -y
16. Memcached sudo apt-get install memcached
17. ImageMagic sudo apt-get install imagemagick libmagick9-dev -y
18. Arial/Verdana etc fonts: sudo apt-get install msttcorefonts
19. VirtualBox
20. Nginx + Passenger
21. Restrcited codes sudo apt-get install ubuntu-restricted-extras -y
22. Terminal
    Set Ctrl+Shift+L for clear+reset in terminal, so the history gets removed on keypress
    Set Ctrl+t for new tab
23. Postgres
    sudo apt-get install postgresql postgresql-devel
    gem install pg

    # change /etc/postgresql/9.1/main/pg_hba.conf from peer to trust
    local all postgres trust

    sudo /etc/init.d/postgresql restart

    use username: postgres + no password in database.yml

24. Reverse scrolling
    If you often work on macs this can reduce your confusion.
    sudo add-apt-repository ppa:zedtux/naturalscrolling
    sudo apt-get update
    sudo apt-get install naturalscrolling -y

Solution
Overwrite the initializer to also accept nil and strings

# config/initializers/money.rb
require 'money'
class Money
  def initialize_with_default_currency(*args)
    args[0] = args[0].to_i if args[0].is_a?(String) or args[0].blank?
    args[1] ||= Money.default_currency
    initialize_without_default_currency(*args)
  end
  alias_method_chain :initialize, :default_currency
end
