  • Right, I thought that might be what you were referring to. This is where we get into weeds technically:

    Those regulations apply to active jamming, which is the use of an electronic device(s) to emit signals that interfere with lawfully approved channels. It is important to note that this holds no practical bearing upon structures as they by definition cannot engage in active jamming, only in passive blocking or coincidental interference.

    What’s being experienced with Walmart’s lack of 5G is likely due to the fact that 5G does not penetrate walls very well. Combine this with the fact that you have hundreds of devices in the same enclosed space trying to talk to the same tower some miles away on the lower bandwidth 5G channel that can penetrate walls, and you can see how 5G access is effectively being “denied” simply by the nature of the business. Walmart could implement an on-premises 5G relay to solve the issue, but why would they want to take on that tech debt? All they are required to do by law is make sure E911 is not impeded by the building or operations of the business. They don’t owe you access to other radio waves when on their premises.

    If this regulation were to somehow be applied to passive blocking like what I’ve described, then Faraday cages would be illegal-- which aren’t, again as long as E911 is not impeded. This would also make high security bamk vaults illegal due to the thick wall construction.





  • 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.



  • Gabe has said multiple times he would never sell Valve to Microshaft.

    Every time I see these “rumors” I can’t help but think that they are a malicious tactic by Microshaft to try and influence their more longshot buyout offers-- Microshaft really really wants Valve, this has been known for at least a decade. And some overzealous young execs are foolishly ready to try and pressure Valve with these bullshit tactics, completely unaware of what dangerous game they are playing legally.

    I have no doubt in my mind Valve will never be sold to Microshaft or come anywhere close to it so long as Gabe or his confidants are at the helm. They are ex-Microsoft employees. They built Windows 3.0. They know it’s inner workings and failings very intimately and they only begrudgingly tolerate Windows because it’s the dominant market share. That’s the whole reason SteamOS and Steam Deck exist, to chip away at Microsoft’s attempts to monopolize PC gaming. And that’s exactly why Microsoft is hoarding IP and restricting their most prestigious titles, like Halo, to Windows through anticheat.

    Whoever is starting these rumors are either pathetically stupid and attention hungry or are spreading misinformation in a hail mary at the behest of Microshaft.



  • 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.
