I recently discovered I had an open mail relay.

I recently needed to take a mysql database export from one docker container and import it into a different docker container.

I tried to spin up a vanilla mailcow-dockerized setup but couldn’t get it to come up.

I kept having a frustrating issue where my 40gig link for all hosts in my 3-node mesh network would go down if one host became unresponsive.

I wanted an easy way to forward ports from my VPS to a host on my local network.

I had an annoying “chicken and egg” problem with nginx proxy manager.

I wanted a quick way in the command line to get the disk usage of a bunch of zip files I downloaded in the previous day.

My manual wireguard site to site solution worked but had latency issues.

I needed to give my CGNAT-backed home internet a way to have a public IP address.

I had a frustrating issue where prometheus blackbox exporter wasn’t able to check one of my websites and I couldn’t figure out why.
