sudo ln -s /usr/bin/gem1.8 /usr/local/bin/gem
sudo ln -s /usr/bin/ruby1.8 /usr/local/bin/ruby
sudo ln -s /usr/bin/rdoc1.8 /usr/local/bin/rdoc
sudo ln -s /usr/bin/ri1.8 /usr/local/bin/ri
sudo ln -s /usr/bin/irb1.8 /usr/local/bin/irb

Install Rails

sudo gem install rails

cat ~/.ssh/id_rsa.pub | ssh user@hostname 'cat >> .ssh/authorized_keys'

If you’re using and Ubuntu virtual machine with VMware Player and are having a problem with the toolbar covering the Ubuntu toolbar then this should fix the problem:

1. Open “C:\Documents and Settings\<your account>\Application Data\VMware\preferences.ini”
2. Add this line to the bottom of the file:    pref.vmplayer.fullscreen.nobar = “TRUE”

The “Application Data” folder in C:\Documents and Settings\<your account>\ is typically a hidden folder so you’ll need to view the hidden files to find it.
