💥 Read this insightful post from Hacker News 📖 📂 Category: ✅ Here’s what you’ll learn: After a long break from working on my hobby operating system, I finally got back into it and finished a very important milestone: a working web server. Web browser accessing HTTP server on my OS Networking was always integral to my hobby project. The first goal was getting the basic networking stack working: Ethernet, IP, ARP, UDP, TCP, DHCP and DNS.

Defer Macro Warning: This is experimental, relies on GCC-specific extensions (__attribute__((cleanup)) and nested functions), and is not portable C. It’s just for fun and exploration.  While working on my operating system project, RetrOS-32, I ran into some of GCC’s less common function attributes. One that stood out to me was the cleanup attribute, which lets you tie a function to a variable. When the variable goes out of scope, that function is called automatically. At first this sounded like an easy way to manage resources in C, a language where you normally have to handle everything by hand.

My scheduler operations implementation A benefit of working on your own operating system is that you’re free from the usual "restraints" of collaboration and real applications. That has always been a major factor in my interest in osdev. You don’t have to worry about releasing your program, or about critical security vulnerabilities, or about hundreds of people having to maintain your code. In the OSDev world you’re usually alone, and that solitude gives you the freedom to experiment with unusual programming patterns. While developing a kernel module for my master’s thesis I came across an article on LWN: …
