Let’s Encrypt, again, Part 2

This site gave me a good starting point. I ran the commands in my WLS Debian instance and then uploaded the keys via cPanel copy & paste, per this site starting at Step 9.

I am a little concerned about this, as matthannan.net is, basically, what everything runs off of, not www.matthannan.net.… Read the rest

Let’s Encrypt, again

This has become buried at nycnyne.net, so I wanted to get this added here. Three more months and I am playing with Let’s Encrypt at Namecheap again. I can get nycnyne.net working again with this one-liner and a copy/paste the key to the cPanel.… Read the rest

Raspberry Pi: SD Card to SSD Drive, part 2

Oh, brother, has this been a mess. I’ve certainly relearned a great deal about Linux partitions and boot sectors and a bunch of other stuff that I used to know cold, but this process has beaten me.

rsyslog & LogAnalyzer, follow-up

Well, it has been a solid day watching these nagging log entries scroll by over and over again.

I just cleared up a cacti issue on Pi1 by determining that I was not actually using cacti for anything and removing it, along with the CRON job that was generating the log entry.… Read the rest

Raspberry Pi POE HAT

I am gearing up to return to this OpenCV project. Changing jobs and such do make hobbies a challenge.
Looking at how to power the Pi once it is installed on the oil tank is causing me some headaches.
I’d love to keep this thing running on WiFi and not have to run an Ethernet cable, but then I am left with having to run an extension cord and power the device via the USB port.… Read the rest
