In this hands-on tutorial, we dive into bit manipulation in x86-64 assembly using Yasm on Ubuntu. We cover the basics of logical operations like AND, OR, XOR, and NOT, then move into shifting (logical vs arithmetic), rotating bits, and why signed vs unsigned matters for shifts.

I explain each concept on paper first, then show real code examples running in GDB to prove how the bits change. We look at patterns in registers, see what happens with negative numbers in two's complement, and even touch on how shifts can multiply or divide by powers of 2.

Perfect if you're learning low-level programming, reverse engineering, or just curious about how bits work under the hood. No prior assembly knowledge needed, but it'll help if you've seen my other videos.
