Switching between Xcodes

Just wanted to "bookmark" the command that I had to go back to a couple of times in order to switch between instances of Xcode:
sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer

Connecting Ubuntu to AirPort Time Capsule

Here is what worked for me:
sudo mount -t cifs -o user=root,password=[your password],rw,hard,nosetuids,noperm,sec=ntlm //192.168.x.x/Data ~/capsule

Make sure you put the correct password and the time capsule ip address in there.
