A few weeks back I mentioned Home Assistant. After I set that up, I bought some Kasa smart outlets. Two have replaced timers, so I no longer have to change the start times as the time of sunset changes throughout the year. A third is set up in my home …Continue reading

I had a Diamond NR770HNMO antenna, and bought a fender bracket mount for my F150. All I needed was an NMO mount and to fish the …Continue reading
This is not my typical type of post, but as I have said, communications and networking are things that excite me greatly. It's why I collect antique telephones, why I enjoy scanner and shortwave listening, why I learned the OSI model and have spent much of my career in and …Continue reading
I recently learned about the program map type in the Linux automounter.
You can read about it here, but there is little information about it, and I was unable to find any web pages about it, so I am writing this post since it might help others.
