minus-squareNiHaDuncan@lemmy.worldlinkfedilinkEnglisharrow-up26·1 year agoHe says this because he kind of ignorantly (his own wordage) wrote in machine code for quite some time before realizing assembly was a thing. So for Linus inline assembly is to machine code as python is to c for a lot of us.
minus-squarejormaig@programming.devlinkfedilinkEnglisharrow-up1·1 year agoWhat does he mean by machine code? Like assembly files or literally 1s and 0s?
minus-squaresolidsnail@programming.devlinkfedilinkEnglisharrow-up2·1 year agoHe was probably working with bytes and not individual bits, but yeah. He basically wrote executables directly (to my understanding).
minus-squareHexarei@programming.devlinkfedilinkEnglisharrow-up2·1 year agoHe didn’t realize assembly was a thing, so he was actually writing machine code instructions
minus-squaremrkite@programming.devlinkfedilinkEnglisharrow-up1·1 year agoOne of my oldest programming books is all about using machine language to program. https://vintageapple.org/apple_ii/pdf/Apple_Machine_Language_1981_(raw-bw).pdf At the time, even assemblers cost money. I remember saving up for Merlin which is an assembler for the Apple II.
