I guess, if assembly mnemonics are too readable for you you can write the machine code in binary. I guess the most interesting part of this is the stuff required to let the loader know what to do with your binary blob (i.e. what the linker would normally do), the rest is just looking up opcodes. Sadly the latter is what the author focuses on.
