making dvds from video files

Lest I forget again, DeVeDe did a decent job of putting an flv file that I had downloaded onto a DVD for playback on any TV and it's apt-gettable on ubuntu.

A fun shell idiom.

To find what's in filea that isn't in fileb, I have always done

cat filea fileb fileb | sort | uniq -u

similar things give you union, intersection, symetric difference etc. Recently I shortened it to

cat filea fileb{,} | sort | uniq -u

which I thought was good fun.
