Outside of very specific deployments and industries, serial port on a modern hardware - if present - is usually overlooked and completely ignored. Over the years it became the floppy of external ports. These days one is more likely to see it as an icon representing I/O port than to physically use it.
Which is exactly why I also didn't see it for what it was - a simple, yet elegant solution to my particular problem. Because as it turns out, serial port still has much to offer even in 2023.

As far as downtimes go, most suck. Then there are some that are more like happy little opportunities to learn something new. When Gitlab in my homelab started returning

Looking at my git history, I've been happily running InfluxDB for years. However nearing the end of 2021, after long time of peaceful coexistence among my monitoring services, some more or less pressing problems emerged:

This is an extension of very helpful article Running Docker on WSL2 without Docker Desktop (the right way) by Felipe Santos. My post attempts to go further and solve a very specific issue within WSL - the absence of nftables support. This is something you might not encounter unless you start running docker in docker or attempt to run docker images that rely on nftables support in some way.
I tend to use Molecule quite heavily and I often end up using docker to emulate actual full blown linux systems or kubernetes cluster in a container, which is where the absence of some kernel features shows up.
