It’s not really a big deal, but I am currently writing this using a linux kernel I compiled from source, which certainly feels like an accomplishment. The Arch Wiki has made the process fairly easy to follow. I just took the stock Arch Linux configuration without changes for now.
The most important part of this is of course that I have the option to do that, to take the source code of this incredible project and build my own kernel binary.
It took roughly 10-15 minutes on a Ryzen 5800X with 32GB RAM. I have compiled other programs before, but none nearly as large and notable as the kernel. I am in fact very close to getting a computer science degree, but that is in no way required to be able to do this. If you are able to follow the wiki-page I linked, you can do it too.
