Let’s build a simple Linux kernel module in C. I tend to use this to test a Secure Boot setup as you’ll be able to see the errors from loading an unsigned module into a kernel where the system requires all kernel modules to be signed.

This is just a simple reference for changing passwords on a LUKS-encrypted volume. There are plenty of places you could go to find this information, but I have it here for my own reference more than anything.
Let’s build a minimal Docker container using Microsoft’s CBL-Mariner 2.0.
If you use the CBL-Mariner 2.0 images that Microsoft provides directly you’re bound to notice that the container image size is much larger than its Alpine counterpart. However, there are a number of things that can be done to optimize the usage of this image to get close to an Alpine-based Docker image.
We’re going to set up a Dev Container for Go development. This will allow us to develop our application in a consistent, easy to use, and reproducible development environment with all the necessary dependencies installed, so we can jump right into working on our application.
