I think you're probably right regarding your opinoin towards limux magazin and linux user. I just read linux magazin some years ago and it was full of hints and prgrams and setup stuff.
further linux magazines in german:
a good pc magazine anyway
(always some little thing about linux, sometimes linux headstories, always al ot about hardware (best tests of all german magazines) and software (mainly windows stuff, but mac and linux as well, and also a lot of plattform independent stuff like programming techniques and computer standards)
