Free digital Linux magazines

Hi there,

I've found two interesting Linux magazines, which can be downloaded monthly as PDF file. You can leave your email address on their website to be informed about new issues (subscribers get the link earlier).

These magazines are not exclusively about Ubuntu linux, but Ubuntu and Ubuntu applications often take part of it. So if you're interested in Linux related distributions and applications, it's definitely worth a try.

Here they are:
