Our walmart installed these price-as-you-go tags a while ago and I have literally seen them change as I walk up to them, and then change again as I walk away. The trick to get them not to change is to be holding your phone at them - the store's AI won't change the tags if it thinks you're filming them.

My Walmart is worse than that. They didn't have any price tags at all. Just video screens with AI avatars of a guy in baggy pants sitting cross-legged on a rug.

When I walk by, he says "Look at my cotton swabs! I offer you the best cotton swabs in the land!"

I say: "Well, how much to they cost?"

He squints at me, looks me up and down for a long while, then says: "For you........ I give to you seven hundred and fifty swabs for two pieces of silver only. Believe me when I say you will search this entire kingdom and not find a better deal!"

Wrong again.

Moreover, many of the big complex systems I've worked on were big and complex mainly because OOP nitwits had designed them. They often didn't understand how computers actually work, lost sight of the fact that they were writing a computer program, and spewed out frameworks that filled countless gigabytes of resident memory with endlessly deep layers of nothingburger abstractions. Maybe that didn't matter so much when memory was cheap, but that's no longer the case.

If you think that there's only one way to deal with large data sets, you're a just noob that needs more experience before spouting your theories.

When I am looking at the contracts my company has for our company phones, I doubt your promise. As an American company, it has decided that providing company phones to its employees is not a core competency of the company. So it outsourced the task to the lowest bidder, and the lowest bidder has bought data plans for our phones which abruptly switch off everything above EDGE, as soon as the data allocation for the period has been exhausted. No warning. No graceful change. Just a hard cut-off. For everyone, including Field Service, who needs to have mobile internet connectivity to get and update trouble tickets.

The ideal for memory safety is to have an air-tight pressure vessel.

With C, you're starting that task with a colander. You've managed to fill two of the colander's holes with silicone caulk. Congratulations.

No one who owns fine art ever needs to sell it. No one who owns vintage cars ever needs to sell them etc.pp.. Of course, you don't need to sell your bitcoins. As long as they are non-distinguishable from random bit patterns, they don't affect anything. But as soon as you selling bitcoins affects the real world, the real world notices and keeps putting up rules, may they be physical realities or legal requirements.

As an anti-racist with a geography degree, this is solving a problem that doesn't exist. Walk into any classroom on earth and chances are good they won't have the mercator projection on the wall, they'll have something better representative of area, often a Robinson projection.
