asm vs asm-lessons
Linux x86_64 assembly learning compared
asm teaches Linux x86_64 assembly through a seven-part series with runnable NASM examples. asm-lessons introduces assembly in the context of FFmpeg, with a path aimed at programmers preparing to contribute.
asm: Learn Linux x86_64 Assembly Programming
A chapter-based introduction to assembly programming for Linux x86_64, with explanations and runnable NASM examples. It suits readers learning how low-level programs work and how assembly interacts with C and the operating system.
asm-lessons: Learn Assembly for FFmpeg
A lesson-based introduction to the assembly language used in FFmpeg, aimed at programmers who want to understand low-level code and prepare to contribute. It assumes familiarity with C pointers and high-school mathematics.

Key differences
- asm covers x86_64 on GNU/Linux, including system calls, memory, floating-point arithmetic, and calling assembly from C; asm-lessons focuses on assembly as used in FFmpeg.
- asm presents seven chapters from processor concepts to higher-level language interaction; asm-lessons uses lessons oriented toward understanding and contributing to FFmpeg.
- asm is aimed at learners seeking a guided foundation in Linux assembly; asm-lessons assumes familiarity with C pointers and high-school mathematics.
- asm lists example prerequisites including 64-bit Linux, make, NASM, and binutils; asm-lessons is learning material rather than a toolchain or contribution workflow.
- asm offers a downloadable PDF and lists volunteer translations in Chinese, Turkish, Korean, and Russian; asm-lessons lists README versions in English, French, Spanish, Turkish, and Chinese, plus a Discord server.
- asm reports its license as NOASSERTION, while its Markdown content is described as CC BY-NC-SA 4.0; asm-lessons notes that assignments are planned but not yet uploaded.
Choose asm if you…
- want a chapter-based introduction to x86_64 assembly on GNU/Linux.
- need examples covering system calls, memory, floating-point arithmetic, or calling assembly from C.
- prefer a downloadable PDF and runnable NASM examples to support learning.
Choose asm-lessons if you…
- already know C pointers and want to learn assembly in the context of FFmpeg.
- are preparing to read or modify assembly code in FFmpeg.
- want a project-focused path toward contributing to FFmpeg.
