in reply to && and and (well, you try searching for an answer)

&& and || should be used inside logical expressions while or should be used between statements for idiomatic error handling ("or die"). Finally, and is only useful for error handling with system.

[Corion]: Hurr. Yesterday I played around with ffmpeg as a new toy and found its "scene" filter great - it detects scene changes. Now I could write a module that splits a given video on its cuts into different scenes. Except I have no use case for that :)
[Corion]: (and also, writing yet another FFmpeg module just to wrap system() and grep through its output isn't all that great ...)
[erix]: cut out advertisements from movies? :)
[erix]: robably not possible (or it would have been done already)
[Corion]: erix: Oooh - yeah, that would be a good application of this, true (except that I don't consume movies-with- separate- advertisements that much nowadays :) )
