Hi, I'm the author. In this particular example, I basically skipped the compiler and linker to create an executable directly, yes. It's certainly a lot of fun, but if you're really trying to become proficient at programming in assembly language, I would recommend reading Assembly Language Step-by-Step: Programming with Linux.

Thanks. I'll be sure to check it out when I get into programming asm.
