Regular readers of this blog have probably noticed that it is now served from a different IP address… Okay, okay, I'm kidding! This blog doesn't have any regular readers, of course.

Anyway, what I'm trying to say is that I recently spent quite some effort to move all my stuff — softwaremaniacs.org, highlightjs.org, their supporting databases and, most importantly, my personal email — to a new and shiny Linode instance under control of an up-to-date Ubuntu.

Ding!

It all started with an email from letsencrypt politely telling me my client software (certbot) must be too old as it uses an obsolete version of their protocol, and it's going to break when they drop support for it. Little did I know at that moment just how hairy a yak I was staring in the eyes…

    Setting up properly configured mail server wasn't an easy walk 15 years ago. Looks like it's still pretty much the same headache

    BTW +1 for RSS
