I have been using Wireguard for about a year & a half, when I switched from ZeroTier to Wireguard for most of my needs. Unfortunately, since the start, my Wireguard configuration has been completely manual, and very annoying since I had to create a new interface for every client.

Parks On The Air, or POTA, is one of the aspects of amateur radio that I have been enjoying -- both hunting and activating. Ever since I starting doing POTA activations, I have been carrying my equipment in a Rubbermaid container, which is bulky and heavy. The only thing it has …Continue reading

This allows me to update my blocked_senders file to defer every email in that format with a 450, using …Continue reading

I've been busy at home, but not working in my home lab. Lately I have been preoccupied by a few things.

First, I have been busy with prepping -- I can see how things are going, and I predict we will need stores of supplies, so I have been busy building …Continue reading

Somehow I have been added to several mailing lists, all run by the same organization. The emails look legit, and are ones that I might have subscribed to, but I cannot get off of them no matter what I do -- it seems that they ignore all requests to be removed …Continue reading
