Install Dell OpenManage on R430 For Ubuntu 20.04
I bought a used Dell R430 server from Ebay. It still had the old hostname showing in the system details on the iDrac. Without the OMSA tool installed on the server, it is hard to change the displayed name. The OMSA tool also enables a lot of other admin functionality as well. I read many […]
Read MoreFrom CSV to JSON using PHP
Had an application where I had to convert a ton of CSV logs to JSON format for ingestion by another system. I didn’t have good luck with Python, so I tried PHP. Posting this work here in the hopes it will help someone else. Keep in mind, this is a basic example and the following […]

There are many occasions where even though a system has enough RAM, there may still be a growing swap usage. The steps I outline here are safe to run on a production host to reduce swap usage […]
Read MoreDDNS script using Cloudflare
ABSTRACT A neighbor (looking at you Chad) recommended cloudflare for my website and I figured I’d try it out. Doing so entailed changing my NS records on my domain at the registrar.

Read MorePrivacy Concern: Amazon Sidewalk – how to turn it off
If you have an Amazon device, like Alexa, Ring, etc, you soon will be sharing your internet connection publicly (at least a small portion of it).

ABSTRACT We have an electronic Z-Wave lock on our back door. This lock works great with our Domoticz home automation system over the Z-Wave interface.
