Hi,
this seems to be a good place to note Michael Schili, who writes perl articles for the (german) iX and Linux Magazin on a monthly basis.

His articles can be found on his website in the apropriate section. The articles are german as far as I know but you can still read the code :)

Those articles originally raised my interest in perl and I learned a _lot_ by reading them!

Thanks!

Regards...

Stefan
