Useful Mac Hacks

If it gets in here, it has to be pretty useful.  I didn't work it out, I'm just trying to hold on to it for posterity.  Always look to the original link for details.

Add a "recent apps" icon to the dock.

defaults write com.apple.dock persistent-others -array-add '{ "tile-data" = {"list-type" = 1; }; "tile-type" = "recents-tile";}' && \killall Dock

Note: I don't know why they include the \ in front of killall - it isn't needed, it merely escapes the 'k'.  If you wanna avoid PATH issues, use /usr/bin/killall.
