Let's do some bit masking

Bit masking, it sounds complicated but it’s not. It’s just working with individual bits inside a number. If you know what a byte is but have never touched bits, that’s what we are going to do today. By the end hopefully you’ll be able to check, set, clear, and toggle any bit in a number.

What is a bit?

A bit is the smallest piece of data a computer has. It’s either 0 or 1. That’s it. Everything your computer does every character on screen, every file is stored as sequences of bits.

Building an HTTP Server from Scratch

Let’s built an HTTP server from scratch using only Zig’s standard library. Just TCP, threads, and the spec. This post goes deep on the four ideas that make it work - parsing requests, building responses, serving static files, and handling connections. I’ll show the important code and link to the full source so you can read the rest yourself.

Source is written in Zig, so I assume you have some knowledge of Zig but it’s not mandatory you can still read thought to understand the concepts. I recommend following along with the code as you read, the explanations here give you the idea, the source gives you the details.
