Updating the cert on a Synapse Matrix standalone server

As usual, logging this so I don’t lose track of it later: https://www.linode.com/community/questions/18963/certbot-error-problem-binding-to-port-80 And the original content in case it goes missing: This is a common CertBot error when using the Standalone plugin (–standalone flag) during the certificate renewal/creation process. In this case, CertBot will attempt to use port 80 to create a temporary web server. You have […]

Migrating a Chia farmer/wallet between servers

Yeah, I’m trying Chia farming with the copious disk space I have. Probably be a waste of effort, but I am learning some interesting things in the process. I started with a simple Windows install and then decided to move to Ubuntu in a VM. The VM farmer can’t plot, but it can do farming […]

Setting up k3s on a single RPi4

Testing out the ability to run some containers on RPi4 and I have a single borrowed device. Most of the tutorials out there describe a multi-node configuration and that’s led to some challenges for me to understand this. First, I started with this tutorial: https://github.com/mhausenblas/kube-rpi This gets you there most of the way, but I […]

The RPi Zero W is…ok…

The recommended solution was to use a proxy for displaying the iFrame, or […]

Add an alias to zsh in MacOS

Nutanix CE challenges

The Nutanix install has been moving along.  I would not say it’s ready for more than lab use, but it’s getting there.  I’m setting up a 3 node cluster, and one of the nodes, which has an Intel motherboard, kept throwing a generic error about not being able to find the sysinfo.  Thanks to the […]

Nutanix in the house

About 2 months ago Nutanix.com released a free software only version of their magic, called Community Edition.  I got on the list for this as quickly as I could, but I haven’t been able to install it until now.  See, I wanted to have an actually cluster, what the call RF2 (Redundancy Factor), which would […]
