Load balancing Ansible Tower cluster

As you might know, I do a bit of YouTubing. One video request I got a couple of times, was to do a video about clustering Ansible Tower behind a load balancer.

Fish, bash, zsh

Over the last year, I've been using fish as my shell on Linux. Before that, I have tried both zsh (with and without oh-my-zsh) and bash. For bash, I wrote my own configuration framework, which - let's be real - everyone needs to do and probably has done at …

Cockpit and FreeIPA

Audit logging

(Happy 2021, may it be better than 2020!)

On my tiny, Raspberry Pi based Fedora systems, I have a lot of audit messages in my journal. And I mean a lot, I mean like over 50,000 over the course of 9 days. That's over 5,500 per …

Packages or binaries?

As much as possible, on my Fedora systems (which runs on my desktop, laptop and a handful of Raspberry Pis), I use what dnf provides me with. The same goes for machines I run other operating systems on, like my pihole server (which runs Raspberry Pi OS …
