For the last two years I've been using Ubuntu Linux for software development.
Last week I got a MacBook Pro and have been changing over. I run a heavily
customized vim setup, so the change was particularly difficult with regards to
my keyboard layout.

These step show what I did to make my Mac work like my Linux machines which all
have caps-lock remapped to control. I used OSX's built in keyboard setup tool
to remap my caps-lock key to be a command key, since command, for the most
part, takes the place of control as the primary shortcut key modifier.

# I want a list of 6 non-administrators who are not the
# current user only if someone is logged in. Otherwise,
# don't check current_user's id.

# instead of this:

if user_signed_in?
  @other_users = User.non_admin.limit(6).where("name IS NOT NULL")
else
  @other_users = User.non_admin.limit(6).where(['id != ?', @user.id]).where("name IS NOT NULL")

To run these examples, you'll need the Ruby MQTT library:

$ gem install mqtt

And you'll need to set the various environment variables the scripts expect to find. To do that, create a file named profile in the same directory you plan to run the scripts from. Fill in the AIO_USER and AIO_KEY values with your own.

$ cat < profile

// npm install; npm start
const http = require('http'),
      faye = require('faye');
const server = http.createServer(),
      bayeux = new faye.NodeAdapter({mount: '/signal', timeout: 45});
bayeux.attach(server);
server.listen(8080);
