Remapping keyboard keys in Mac OSX

Use KeyRemap4MacBook to remap keys on your OSX keyboard.

It'll enable "FN + Numpad" by default. What I would really like is a way to do "Left/Up/Down/Right" without using the arrow cursor which forces my hand to shift down the keyboard too much. The utility provides a "Vi Mode" where you can map "FN + hjkl" for Left/Up/Down/Right.

To change CapsLock to Escape you need to download another utility from the website.

Using curl to post data to a rails app

curl -X POST -d "location[lat]=111&location[lng]=222" http://localhost:3000/users/123/devices/456/locations

However rails require authenticity token. To overcome that just turn forgery protection off.

# config/environment.rb
config.action_controller.allow_forgery_protection = false
