The socket is in a weird spot on Ubuntu - add this symbolic link to put it where everyone expects:

ln -s /var/run/mysqld/mysqld.sock /tmp/mysql.sock

You'll notice that readline is missing when attempting to run the console on Ubuntu.

sudo apt-get install install libreadline5-dev libncurses5-dev
rvm pkg install readline
cd $HOME/.rvm/src/ruby-1.9.2-p0/ext/readline
rvm remove 1.9.2
rvm install 1.9.2 --with-readline-dir=$rvm_path/usr

Tech-ing Up: Learning basic programming

Coming from http://www.reddit.com/r/canada/comments/m1494/looking_for_a_developer_advocate_for_shopify/ or elsewhere? Awesome.

This is a guide for learning the bare minimum needed for effectively working as a junior programmer or developer advocate at most software companies.

If you haven’t ever programmed before, don’t sweat it. Those who would be good fits at this job are naturally attuned to this stuff and their innate curiosity makes it a cakewalk. If you’re finding that it’s a frustrating experience the entire way through, then you should consider doing something else for a little while before you come back to give it another shot.

A first stab at programming

  request.env['warden'].authenticate? and request.env['warden'].user.admin? # or whatever manner your admin role can be determined
end

  mount Resque::Server.new, :at => "/resque"
end
