OSX, Better pdf quartz filter compression

The standard quartz filter for pdf compression makes pdf's to small
But you can create your own, fully customises Quartz Filters using your Mac's ColorSync Utility.

See: http://meyerweb.com/eric/thoughts/2010/02/25/better-pdf-file-size-reduct...

For Mavericks the customized compression filters will not show up in Preview.
Fix: copy your filter from /Users/YourName/Library/Filters/
to /Library/PDF Services/ and the quartz filters will be back in preview.

OSX, terminal, Extract mp3 from .mov

You can extract audio from a .mov file with quicktime, but it will keep it in the mov container.

To properly extract mp3 audio from a .mov file use mplayer with the "-dumpaudio" option:
mplayer file.mov -dumpaudio -dumpfile audio.mp3
