We look at configuring and running training in the cloud.
We look into how to use jreleaser and deploy our code to Github and creating release documentation with some simple steps.
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…
We look into Ceph Rados and try to figure out how Ceph stores data. The main goal is to read data from one cluster as raw objects and write it back to another cluster.
After a critical failure, we look into resizing an OSD in our Ceph environment. Unfortunately, the drive is entire, so resize of the OSD was the only option to start the service.
We look into the PWNKit vulnrability and how it works. PWNKit is a linux exploit that have been in linux environments for over 12 years. We look at how it works and what is required to be vulnrable and different approaches to secure your system.
