Keeping track of your disks in a Ceph cluster is important so you could replace them in time before data loss. In this video we look into how to use SMART data to run a machine learning prediction in order predict when a disk fails. SmartMonTools is used locally to fetch the data. The data…

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…

Shutting down a java application gracefully is required to handle java scaling in kubernetes. Shutdown is handled via a hook in java and I’m doing an live coding example where I add code to wait until process is done.

In this video, we look into installing an Openstack Compute node and connecting it with our controller node.
