@angusm @jack_daniel @pluralistic Yup. (Years ago, I was at a NANOG (North American Network Operators Group) meeting where a nearby street had a line of backhoes parked. I think it was a warning.)

@mattblaze The article spoke of unsanitary conditions during processing. I'm trying to figure out just what seafood processing plant would need to have Cs-137 around…

Just think—if we hadn't switched to semiconductor RAM, memory management could have been done by a core daemon, as opposed to the demon core. Gives new meaning to a process's storage requirements blowing up…#obscureReferences

My spouse and I now have an interesting experiment going: which enhances your 5G reception more, getting a Covid shot and a flu shot in the same arm on the same day, or getting one in each arm? Confounding factors: we have different length arms, and I'm not sure which is a better match for 5G wavelengths. Also, I use a computer a lot more, which means that the extra microchips I've just been injected with will help me a lot more.

@ricci You never used classic APL, did you? If you think about it, a - overstruck with a : looks like a ÷, which was a symbol on the APL keyboard. Guess what? It was accepted as such. For that matter, if you overstrike an F with an L, it looks like an E—and since classic APL used hardcopy terminals, what you saw on the paper had to be what you got, so that worked, too.
