Linux by example – Building make and a couple of common languages

I’m trying to solve all the Advent of Code puzzles in this video series.

I will compile a version of Java 17 and try out the new switch statement. In the new Java version, the switch statement will give you a lot more flexibility when it comes to types and other interesting functions. Building Java gave me some insights into what is possible and not in Linux and Windows.

We look closer at an encryption algorithm used in communication today in order to establish secrets at two endpoints.

We look into how to setup libvirt running virtualized machines with the disk data stored in an RBD pool in Ceph. We talk about the installation process and configuring ceph and storage pool.

In this video, we test our installation, adding volumes, making backups, and working with instances.

We will look into using Quarkus, a framework for building java endpoints in a reactive manner. Change code, package structure or class names and the server will restart and just work.
