Unison and file synchronisation

This seems to be working very nicely between various machines on the network.  I am mainly running it from the MacBook Air to the Linux box.  I might configure it to work with the NSLU2 in the loft but there is not so much room up there at the moment.  Also I need to re-establish the off-site back up some time.  

This is a very well written guide for Unison if you want to read any further.  

Rotating Video

If you need to rotate video then I found that this command will rotate 90 degrees right.

mencoder -ovc lavc -lavcopts vcodec=mjpeg -vf rotate=1 -oac pcm input.mov -o output.avi

Sometimes we record movies rotated.
