From time to time you may want to quickly copy a raspberry pi image from one system to another….but only have a smaller SD card. Or you started your project as a tryout on a crazy 64GB sd card, and realize later that 8GB would be way enough. So what you want to do, is resize the source image to the smallest size possible, flash it to the new smaller SD card, and expand it again to its new maximum on the new SD card. And so far that process can be very long and painful….but luckily there is a very handy script for that, called PiShrink. I am using the mac version, but there is also a linux version.

Why a new mail server implementation?
Mox aims to make “running a mail server” easy and nearly effortless. Excellent quality mail server software exists, but getting a working setup typically requires you configure half a dozen services (SMTP, IMAP, SPF/DKIM/DMARC, spam filtering). That seems to lead to people no longer running their own mail servers, instead switching to one of the few centralized email providers. Email with SMTP is a long-time decentralized messaging protocol. To keep it decentralized, people need to run their own mail server. Mox aims to make that easy.
