Malcolm Herbert presented a talk to do with video editing the Tour de France to capture all the helicopter views only. He did it by using filtering on the sound that the Helicopter motors make.

I gave a quick live demo of LVM snapshoting which I find useful.

Create snapshot

lvcreate -L5G -s -n rootsnap /dev/vg.lvm.sol/root

Do something risky ie: an upgrade

apt-get update; apt-get upgrade; apt-get dist-upgrade

Upgrade went ok? - Yes: Delete snapshot

  lvremove /dev/vg.lvm.sol/rootsnap

- No: Revert to snapshot & reboot

  lvconvert --merge /dev/vg.lvm.sol/rootsnap
  reboot
