This post covers building and testing a minimal, but still useful, C

foundation for some upcoming posts/projects on programming Linux,
userland networking and interpreters.

During a cleaning spree I decided that it was time to recycle two old laptops that were just collecting dust on a shelf for many years. Although I didn't have any purpose for them anymore, I realised that the displays were still perfectly fine.
