  • Elon founded SpaceX in 2002. He said he wanted to build reusable, cost effective space platform where rocket boosters could land themselves and be refurbished with low turn-around times to fly multiple missions.

    People laughed at the idea of a rocket that could land itself upright. And after countless tests that resulted in magnificent fiery failures and flops, a private American company is now responsible for launching crew and cargo to the ISS so we don’t have to rely on Russia or ELA alone, and has more recently gone on to develop the largest rocket ever made.

    In the 22 years since it’s inception, SpaceX has designed it’s own:

    • Rockets
    • Engines
    • Rocket Propellant
    • Satellites and base stations
    • Bespoke robust communications network
    • Ground support structure (including a moving robotic tower named “Mechanical”)
    • Crewed mission vehicle platform
    • The world’s biggest fucking rocket

    Say whatever you want about his beliefs, his opinions, his shit takes-- point me to another company that has done even half of that in that amount of time, or had nearly as monumental of an impact on the global space industry and America’s access to space in the last two decades.

    And if y’all haven’t yet already, do yourselves a favor and look up NASASpaceflight on YouTube, watch their most viewed videos, which should be some of the SpaceX tests. You’ll come to understand why shit blowing up is normal and a good thing with SpaceX: because they prototype and develop iteratively and rapidly, intentionally testing to failure so they know exactly how far from failure their nominal conditions would be. If they did not do this, the platform would not be safe and they would be getting fucked by a camel wearing another camel’s skin for kicks.




  • 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 know what’s ironic about all this is, as someone who has seen game dev pitches (not good ones), they arguably had their shit together more than most aspiring game devs. Looking back at the skeletals, ya know they actually may have had a chance of getting somewhere. They knew absolutely nothing about the technical side, but hardly any game devs actually do. They probably still stand a better chance today of developing this than some game studios asset-mashing in Unity or Unreal. That’s the true state of game dev.
