Disable mouse acceleration on Mac

Mouse acceleration makes it hard for me to point and click things based on muscle memory, so I turn it off by entering into the terminal:

defaults write .GlobalPreferences com.apple.mouse.scaling -1

Optionally, you can make an alias in ~/.profile and just enter the alias when you need to re-disable it, which you'll have to do often as the Mac resets this when you adjust mouse speed and sometimes upon login:

alias ma="defaults read .GlobalPreferences com.apple.mouse.scaling; defaults write .GlobalPreferences com.apple.mouse.scaling -1"

Note that the first command prints the current mouse acceleration, and the second one changes it.

Please let me know if you know a clean way to persist this setting.
