Thanks for sharing, the second post is exactly about this topic:

serversfor.dev/linux-inside...
System calls: how programs talk to the Linux kernel
System calls are how programs ask the kernel to do things. Learn how they work, how to trace them, and why this gives you troubleshooting superpowers.

There is already a second part: serversfor.dev/linux-inside... I am not completely satisfied with it, but it's a work in progress. :) Btw you can find the series page here: serversfor.dev/linux-inside...

Thanks for the feedback! This post (and the series) is intentionally an introductory one. I'm aiming at developers who mostly know Linux through "run this command" style tutorials, and don't need deep OS theory for their daily work. There are already great resources about kernel internals.

Thanks for sharing this @steveklabnik.com! I am a beginner writer so this kind of feedback means a lot. I'm turning this into a whole series, making topics like this less mystical for devs.
