  • 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.



  • 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.








  • If it wasn’t obvious that the Debian box is a parody, here’s what the Japanese Chinese text along the top reads on each box:

    Please read the instructions carefully and use it under the guidance of a physician. It is strictly prohibited to be used in food and feed processing.

    Please read the installation instructions carefully and use it under the guidance of the administrator. It is strictly prohibited to use for server installation.

    so yes, the title is correct-- this is not a coincidence, the Debian box was made explicitly for this joke

    edit: thanks for the correction folks, honestly thought it looked more like Japanese than Chinese at first glance and I am obviously not an expert in either. Appreciate the call-out, very deserved.




  • 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.
