Hi! đź‘‹

I’m Grumpy, and I make content about Linux, Servers, and HomeLabs and build things I think are neat. I use this site to share all those things.

You can find me on various social media platforms linked below. I also share written content and projects on this site. (I’m also joining more platforms, so don’t panic)

NAMING THINGS IN A HOMELAB

There’s an old joke in Programming that 90% of your time is spent naming things, and I think this extends into Homelabs and any other computer environment. Names are there give your systems identifiable places, can describe where they are and what they do, and are the easiest way to identify something, so giving some thought into a naming system is worth it.

Essentially, it’s what lets you connect your privately addressed network to a publicly addressed network and have things work.

HOW MY HOMELAB BECAME CRITICAL INFRASTRUCTURE DURING A TORNADO

I recently made a design change to my homelab that paid off in leaps and bounds, and just secured my homelab as a part of my critical infrastructure during emergencies. This change was a pretty simple idea, but recently proved itself during a recent tornado near my home. This post will largely be tooting my own horn, sharing why I think this is a good idea, but will also talk about severe weather and have some pictures.

SORT EVOLUTION MAIL FILTERS WITH PYTHON

I really like filtering my mail. I tend to only need to act on a very small set of messages coming in, so I filter everything such as Ads, FYIs, Cron Jobs, etc to folders and just leave the important stuff in my inbox. Unfortunately though, I now have a few hundred rules, as I keep things separated out to let me have multiple conditions for single senders and keep everything fairly organized.
