  • You’re remembering correctly, every other logic gate can be built from NAND gates, which is the foundation of this sort of minimal-instruction-set exercise. Beyond that, you need to be able to move data and change your program counter (jump, often conditionally). Then, if you want parity with modern instruction sets beyond just being turning complete, you need return and interrupt for control flow.



  • Bookmarking your comment so I can come back to it in a couple hours, if I hopefully remember to.

    But yes, almost. I don’t think the interrupt is necessary and the return isn’t under certain architectures. I have a doc on my computer somewhere where I was investigating what the absolute minimum was to make a turning complete machine and, to my recollection, there was only 4-6 instructions that were absolutely necessary. The ones I remember off the top of my head are NAND, MOV, JUMPIF, and then I believe I included NOP in accordance with some principle. RET and INT were convenience features in this design.










  • You illustrated the point better than I had the energy to do-- I simply don’t care enough to be that eloquent because the majority of what I get is nonsense in return. So instead of wasting my time, I chose to take the lazy route and encourage people to come to a consensus on this one key point so that the point you made would become irrefutable.

    Neither trans nor cis are slurs by default, but anything can be a slur if used in a derogatory manner-- I think some comedian had a bit about this, but I can’t recall who and I’m sure even if I did there’s a good chance someone would give me a nasty label for saying such comedian made a good point…

    But the same people that say trans can be a slur, cannot deny in good faith that cis cannot be a slur. They are both simple classifiers with no basis on prejudice. But some people will still argue they are slurs simply because they are used prominently in derogatory contexts.
