I just picked up a new raspberry pi 3 and ran into a weird problem: after I assigned a static IP to eth0, eth0 was assigned both the static IP, and an IP from dhcp. I don't use debian (the distro that raspbian is based off) often, so
First, let me say that Let's Encrypt is just fucking awesome. It took me all of 30 minutes to replace my old self-signed cert with a signed and trusted one. It's kind of ridiculous that it would take until 2016 for free domain validation certificates to
