In this video we create a invoice template that looks alot like an invoice from one of my first videos. We will go through all the different parts of a invoice that is required and how to go from a data XML to an PDF.

In this video series, I try to challenge myself with the Advent of Code trials. Each solution will be published to Github, and I hope you will learn something from my coding mistakes and perhaps send some code my way on how you have done these challenges. I know by reading code, so this is…

Unlock the full potential of Ceph debug flags in this insightful video! Join us as we explore two crucial debug flags: file writing and memory persistence. Learn how to set and leverage these flags to enhance your Ceph system’s performance and ensure data resilience in case of a crash.

In this video we will cover what I use in my ceph cluster. I’m not an hardware reviewer but this is an example of what kind of hardware that could be used in a ceph cluster. Especially if you want to create a cluster for home use or testing.

We look into how to set up a good Crush Map and handle the placement and device types of your OSDs in your clusters. The crush map describes where, what type, how much and what is your failure domain or safety requirements. One thing we will do a lot throughout this demonstration is to view…
