2,3 Setting a Static IP Address

The process listed no longer works for the current version of software.

Note from the Author or Editor:
OK - this is a major change to this recipe. I'd suggest this needs to wait for the third edition, for a proper fix and for now, the following is added at the start of the Solution section: Note that recent changes to Raspbian mean that the method below may not work. Please see: https://www.modmypi.com/blog/how-to-give-your-raspberry-pi-a-static-ip-address-update for an alternative approach.

"Discussion" section

Describing how two images are compared when detecting motion, it states "When the first image is subtracted from the first..." It should say, "When the first image is subtracted from the second..."

Note from the Author or Editor:
The reader is exactly right - change "When the first image is subtracted from the first ..." to "When the first image is subtracted from the second ..."
